PART I

Item 1. Business.

Overview

Leucadia National Corporation ("Leucadia" or the "Company") is a diversified holding company focused on long-term value creation to maximize shareholder value. Our financial services businesses and investments include Jefferies (investment banking and capital markets), Leucadia Asset Management (asset management), Berkadia (commercial mortgage banking, investment sales and servicing), HomeFed (real estate company), FXCM (provider of online foreign exchange trading services) and Foursight Capital (vehicle finance). We also own and have investments in a diverse array of other businesses, including National Beef (beef processing), HRG Group (consumer products), Garcadia (automobile dealerships), Linkem (fixed wireless broadband services in Italy), Vitesse Energy and JETX Energy (oil and gas production and development), Idaho Timber (manufacturing) and Golden Queen (gold and silver mining project). The structure of each of our investments was tailored to the unique opportunity each transaction presented. Our investments may be reflected in our consolidated results as consolidated subsidiaries, equity investments, securities or in other ways, depending on the structure of our specific holdings.

We continuously review acquisitions of businesses, securities and assets that have the potential for significant long-term value creation, invest in a broad array of businesses, and periodically evaluate the retention and disposition of one or more of our existing businesses and investments. Changes in the mix of our businesses and investments should be expected.

At December 31, 2017, we and our investee companies had approximately 36,700 full-time employees, of which approximately 12,700 were full-time employees of Leucadia and our consolidated subsidiaries.

Our executive offices are located at 520 Madison Avenue, New York, NY 10022, as is the global headquarters of Jefferies, our largest subsidiary in terms of invested capital. Our primary telephone number is (212) 460-1900 and our website address is www.leucadia.com.

The following discussion should be read in conjunction with the Risk Factors presented in Item 1A of Part I and the Cautionary Statement for Forward-Looking Information and Management's Discussion and Analysis of Financial Condition and Results of Operations set forth in Item 7 of Part II.

Recent Events

In January 2017, we sold 100% of Conwed Plastics (“Conwed”) to Schweitzer-Mauduit International, Inc., (NYSE:SWM) for $295 million in cash plus potential earn-out payments in 2019, 2020 and 2021 totaling up to $40 million in cash to the extent the results of Conwed’s subsidiary, Filtrexx International, exceed certain performance thresholds. We recognized a pre-tax gain of $178 million (net of working capital adjustments) on the sale of Conwed during 2017.

Also in January 2017, we participated in a preferred equity financing for Linkem. Existing shareholders, along with funds managed by BlackRock, invested €100 million in cash in exchange for shares of Linkem to fund future expansion plans, of which Leucadia's share was €30 million. The financing was based on a pre-money valuation of €700 million (post-money valuation of €800 million) and our fully-diluted ownership post-transaction is 53%.

Jefferies

Jefferies is the largest independent U.S. headquartered global full-service, integrated securities and investment banking firm. Jefferies largest subsidiary, Jefferies LLC, was founded in the U.S. in 1962 and its first international operating subsidiary, Jefferies International Limited, was established in the U.K. in 1986. On March 1, 2013, Jefferies Group, Inc. converted into a limited liability company (renamed Jefferies Group LLC) and became an indirect wholly owned subsidiary of Leucadia. Following the merger, Jefferies Group LLC retains a credit rating separate from Leucadia and remains an SEC reporting company, filing annual, quarterly and periodic financial reports. As of November 30, 2017, Jefferies had 3,450 employees in the Americas, Europe, the Middle East and Asia. The net book value (assets less liabilities and noncontrolling interests) of our investment in Jefferies was $5.6 billion at December 31, 2017.

Investment Banking

Jefferies industry coverage groups include Consumer and Retail; Energy; Financial Institutions; Healthcare; Industrials; Real Estate; Gaming and Lodging; Technology; Media and Telecommunications; Financial Sponsors; and Public Finance.

Equity Capital Markets

Debt Capital Markets

Jefferies provides a wide range of debt and acquisition financing capabilities for companies, financial sponsors and government entities. Jefferies focuses on structuring, underwriting and distributing public and private debt, including investment grade debt, high yield bonds, leveraged loans, municipal debt, mortgage- and other asset-backed securities, and liability management solutions.

In the restructuring and recapitalization area, Jefferies provides to companies, bondholders and lenders a full range of restructuring advisory capabilities as well as expertise in the structuring, valuation and placement of securities issued in recapitalizations.

Equities

Equities Research, Sales and Trading

Jefferies provides its clients full-service equities research, sales and trading capabilities across global securities markets. Jefferies earns commissions or spread revenue by executing, settling and clearing transactions for clients across these markets in equity and equity-related products, including common stock, American depository receipts, global depository receipts, exchange-traded funds, exchange-traded and over-the-counter (“OTC”) equity derivatives, convertible and other equity-linked products and closed-end funds. Jefferies equity research, sales and trading efforts are organized across three geographical regions: the Americas; Europe and the Middle East and Africa (“EMEA”); and Asia Pacific. Jefferies clients are primarily institutional market participants such as mutual funds, hedge funds, investment advisors, pension and profit sharing plans, and insurance companies. Through its global research team and sales force, Jefferies maintains relationships with its clients, distributes investment research and strategy, trading ideas, market information and analyses across a range of industries and receives and executes client orders. Jefferies equity research

3

covers over 2,000 companies around the world and more than 800 additional companies are covered by nine leading local firms in Asia Pacific with whom Jefferies maintains alliances.

Equity Finance

Jefferies Equity Finance business provides financing, securities lending and other prime brokerage services. Jefferies offers prime brokerage services in the U.S. that provide hedge funds, money managers and registered investment advisors with execution, financing, clearing, reporting and administrative services. Jefferies finances its clients’ securities positions through margin loans that are collateralized by securities, cash or other acceptable liquid collateral. Jefferies earns an interest spread equal to the difference between the amount Jefferies pays for funds and the amount Jefferies receives from its clients. Jefferies also operates a matched book in equity and corporate bond securities, whereby Jefferies borrows and lends securities versus cash or liquid collateral and earns a net interest spread. Jefferies offers selected prime brokerage clients the option of custodying their assets at an unaffiliated U.S. broker-dealer that is a subsidiary of a bank holding company. Under this arrangement, Jefferies directly provides its clients with all customary prime brokerage services.

Wealth Management

Jefferies provides tailored wealth management services designed to meet the needs of high net worth individuals, their families and their businesses, private equity and venture funds and small institutions. Jefferies advisors provide access to all of its institutional execution capabilities and delivers other financial services. Jefferies open architecture platform affords clients access to products and services from both its firm and from a variety of other major financial services institutions.

Fixed Income

Fixed Income Sales and Trading

Jefferies provides its clients with sales and trading of investment grade corporate bonds, U.S. and European government and agency securities, municipal bonds, mortgage- and asset-backed securities, leveraged loans, consumer loans, high yield and distressed securities, emerging markets debt, interest rate derivative products, as well as foreign exchange trade execution and securitization capabilities. Jefferies is designated as a Primary Dealer by the Federal Reserve Bank of New York and Jefferies International Limited is designated in similar capacities for several countries in Europe. Additionally, through the use of repurchase agreements, Jefferies acts as an intermediary between borrowers and lenders of short-term funds and obtains funding for various of its inventory positions. Jefferies trades and makes markets globally in cleared and uncleared swaps and forwards referencing, among other things, interest rates, investment grade and non-investment grade corporate credits, credit indexes and asset-backed security indexes.

Jefferies strategists and economists provide ongoing commentary and analysis of the global fixed income markets. In addition, Jefferies fixed income desk strategists provide ideas and analysis to clients across a variety of fixed income products.

Asset Management

Jefferies manages and provides services to a diverse group of alternative asset management platforms across a spectrum of investment strategies and asset classes. Jefferies is supporting and developing focused strategies managed by distinct management teams. These services are often provided in conjunction with the Leucadia Asset Management ("LAM") platform. Products currently offered to pension funds, insurance companies, sovereign wealth funds, and other institutional investors through these platforms include systematic quantitative and global equity event-driven strategies. Jefferies also provides back office, accounting, legal, risk and compliance via service level agreements for certain LAM entities. LAM provides general oversight and marketing services to Jefferies asset management entities.

Competition

All aspects of Jefferies business are intensely competitive. Jefferies competes primarily with large global bank holding companies that engage in capital markets activities, but also with other broker-dealers, asset managers and investment banking firms. The large global bank holding companies have substantially greater capital and resources than Jefferies does. Jefferies believes that the principal factors affecting its competitive standing include the quality, experience and skills of its professionals, the depth of its relationships, the breadth of its service offerings, its ability to deliver consistently its integrated capabilities, and its culture, tenacity and commitment to serve its clients.

Regulation

Regulation in the United States. The financial services industry in which Jefferies operates is subject to extensive regulation. In the U.S., the Securities and Exchange Commission (“SEC”) is the federal agency responsible for the administration of federal securities laws, and the Commodity Futures Trading Commission (“CFTC”) is the federal agency responsible for the administration of laws relating to commodity interests (including futures and swaps). In addition, the Financial Industry Regulatory Authority (“FINRA”) and the National Futures Association (“NFA”) are self-regulatory organizations that are actively involved in the regulation of financial services businesses. The SEC, CFTC, FINRA and the NFA conduct periodic examinations of broker-dealers, investment advisors, futures commission merchants (“FCMs”) and swap dealers. The designated examining authority for Jefferies activities as a broker-dealer is FINRA, and the designated self-regulatory organization for Jefferies FCM activities is the NFA. Financial services businesses are also subject to regulation by state securities commissions and attorneys general in those states in which they do business.

Broker-dealers are subject to SEC and FINRA regulations that cover all aspects of the securities business, including sales and trading methods, trade practices among broker-dealers, use and safekeeping of customers’ funds and securities, capital structure of securities firms, anti-money laundering efforts, recordkeeping and the conduct of directors, officers and employees. Registered advisors are subject to, among other requirements, SEC regulations concerning marketing, transactions with affiliates, disclosure to clients, and recordkeeping; and advisors that are also registered as commodity trading advisors or commodity pool operators are also subject to regulation by the CFTC and the NFA. FCMs, introducing brokers and swap dealers that engage in commodities, futures or swap transactions are subject to regulation by the CFTC and the NFA. Additional legislation, changes in rules promulgated by the SEC, CFTC, FINRA or NFA, or changes in the interpretation or enforcement of existing laws or rules may directly affect the operations and profitability of broker-dealers, investment advisors, FCMs and swap dealers. The SEC, CFTC, FINRA, NFA, state securities commissions and state attorneys general may conduct administrative proceedings or initiate civil litigation that can result in adverse consequences for Jefferies and its officers and employees (including, without limitation, injunctions, censures, fines, suspensions, membership expulsions, or revocations of licenses and registrations). In addition, broker-dealers, investment advisors, FCMs and swap dealers must also comply with the rules and regulation of clearing houses, exchanges and trading platforms of which they are a member.

Regulatory Capital Requirements. Several Jefferies entities are subject to financial capital requirements that are set by regulation. Jefferies is a dually-registered broker-dealer and FCM and is required to maintain net capital in excess of the greater of the SEC or CFTC minimum financial requirements. As a broker-dealer, Jefferies is subject to the SEC's Uniform Net Capital Rule (the "Net Capital Rule"). Jefferies has elected to compute its minimum net capital requirement in accordance with the “Alternative Net Capital Requirement” as permitted by the Net Capital Rule, which provides that a broker-dealer shall not permit its net capital, as defined, to be less than the greater of 2% of its aggregate debit balances (primarily customer-related receivables) or $250,000 ($1.5 million for prime brokers). Compliance with the Net Capital Rule could limit Jefferies operations, such as underwriting and trading activities, that could require the use of significant amounts of capital, and may also restrict its ability to make loans, advances, dividends and other payments.

As a non-clearing FCM, Jefferies is required to maintain minimum adjusted net capital of $1.0 million.

Jefferies subsidiaries that are provisionally registered swap dealers will become subject to capital requirements under the Dodd-Frank Act once the relevant rules become final. For additional information see Item 1A. Risk Factors.

Jefferies Group LLC is not subject to any regulatory capital rules.

See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, and Note 25 to our consolidated financial statements for additional discussion of net capital calculations.

Regulation outside the United States. Jefferies is an active participant in the international capital markets and provides investment banking services internationally, primarily in Europe and Asia. As is true in the U.S., Jefferies international subsidiaries are subject to extensive regulations proposed, promulgated and enforced by, among other regulatory bodies, the European Commission and European Supervisory Authorities (including the European Banking Authority and European Securities and Market Authority), U.K. Financial Conduct Authority, Hong Kong Securities and Futures Commission, the Japan Financial Services Agency and the Monetary Authority of Singapore. Every country in which Jefferies does business imposes upon it laws, rules and regulations similar to those in the U.S., including with respect to some form of capital adequacy rules, customer protection rules, data protection regulations, anti-money laundering and anti-bribery rules, compliance with other applicable trading and investment banking regulations and similar regulatory reform. For additional information see Item 1A. Risk Factors.

Leucadia Asset Management

During 2013, we formed LAM, a registered investment advisor, through which we are developing and investing in focused alternative asset management businesses. As the advisor and/or general partner to various private investment funds or other types of investment vehicles, LAM provides advisory, portfolio management and operational services to accredited investors and/or qualified purchasers. Once an investment platform is formed, it is typical that LAM or Jefferies will be an initial or major investor.  LAM's revenues derive from management fees and/or performance fees based on investment returns generated for the investors, as well as the return on our invested capital. Our strategy is to grow third party assets under management, while earning management fees and a reasonable return on our capital until the capital is returned to us. Our LAM and other asset management strategies primarily include Folger Hill Asset Management LLC ("Folger Hill"), a multi-manager discretionary long/short equity hedge fund platform; Topwater Capital ("Topwater"), a first-loss product; CoreCommodity Management LLC, an asset manager that focuses on commodities strategies; Tenacis Capital, a systematic macro investment platform; Lake Hill, an electronic trader in listed options and futures across asset classes; as well as several other smaller businesses. In addition, several investment management businesses, including Jefferies Strategic Investments Division, operate under Jefferies and are included under the marketing umbrella of the LAM platform.

Berkadia

Berkadia Commercial Mortgage LLC, and its associated entities, is a joint venture formed in 2009 with Berkshire Hathaway that provides capital solutions, investment sales advisory and mortgage servicing for multifamily and commercial properties. We and Berkshire Hathaway each have a 50% equity interest in Berkadia.

Berkadia originates commercial real estate loans, primarily in respect of multifamily housing units, for Fannie Mae, Freddie Mac and the FHA using their underwriting guidelines, and will typically sell the loan to such entities shortly after it is funded. Provided Berkadia adheres to their guidelines, these government-related entities must purchase the loan at the face amount plus accrued interest with Berkadia retaining the mortgage servicing rights. In addition, as a condition to Fannie Mae’s delegation of responsibility for underwriting, originating and servicing of loans, Berkadia assumes a shared loss position throughout the term of each loan sold to Fannie Mae, with a maximum loss percentage of approximately one-third of the original principal balance. During 2017, Berkadia originated $16.7 billion in Fannie Mae, Freddie Mac and FHA loans. Berkadia also originates and brokers commercial/multifamily mortgage loans which are not part of the government agency programs. During 2017, Berkadia closed $7.2 billion of loans in this capacity for life companies, conduits and other third-parties.

In addition, Berkadia originates loans for its own balance sheet. These loans provide interim financing to borrowers who intend to refinance the loan with longer-term loans from an eligible government agency or other third party (“Bridge loans”). Bridge loans are typically floating rate loans with 1 to 3 year maturities. During 2017, Berkadia originated $587.3 million of such loans. Berkadia held $672.0 million of Bridge loans on its balance sheet at December 31, 2017.

Berkadia also provides services related to the acquisition and disposition of multifamily real estate projects, including brokerage services, asset review, market research, financial analysis and due diligence support. During 2017, Berkadia closed over $7.8 billion in sales transactions.

Berkadia is a servicer of U.S. commercial real estate loans, performing primary, master and special servicing functions for U.S. government agency programs, commercial mortgage-backed securities transactions, banks, insurance companies and other financial institutions. Berkadia is an approved servicer of loans for Fannie Mae, Freddie Mac and the FHA. As of December 31, 2017, Berkadia serviced approximately 17,000 loans with an unpaid principal balance of $205.9 billion.

As a servicer, Berkadia is frequently responsible for managing, on behalf of its investors and borrowers, the balances that are maintained in custodial accounts for the purposes of collecting and distributing principal and interest, and for managing and disbursing various reserve accounts related to the mortgaged properties among other things. Berkadia derives certain economic benefits from administering these custodial accounts. Such balances totaled in excess of $4.5 billion as of December 31, 2017.

Our only capital contribution to Berkadia, in the amount of $217.2 million, was made at the time Berkadia was formed in 2009. Through December 31, 2017 we have received cumulative cash distributions of $562.0 million. At December 31, 2017, the net book value of our investment in Berkadia was $210.6 million, and we report Berkadia as an equity investment in our financial statements. Berkadia's strategic priorities include continued value creation by growing origination and sales advisory volumes, expanding servicing engagements with third parties, and leveraging data and technology to deliver proprietary solutions to clients.

Berkadia is required under its servicing agreements to maintain certain minimum servicer ratings or qualifications from the rating agencies. A downgrade below a certain level may give rise to the right of a customer or trustee of a securitized transaction to

6

terminate Berkadia as servicer. Berkadia currently maintains approvals or ratings from Moody’s Investors Service, Fitch Ratings, Standard & Poor’s, Morningstar Credit Ratings and Dominion Bond Rating Services. These ratings currently exceed the minimum ratings required by the related servicing agreements. Ratings issued by the rating agencies can be withdrawn or lowered at any time. In addition, Fannie Mae and Freddie Mac retain broad discretion to terminate Berkadia as a seller/servicer without cause.

HomeFed Corporation

HomeFed is a developer and owner of residential and mixed-use real estate properties in California, New York, Florida, Virginia, South Carolina and Maine. After many years in the entitlement process, the majority of HomeFed's assets are now either operating real estate or entitled land ready for sale. HomeFed is a public company traded on the NASD OTC Bulletin Board (Symbol: HOFD). We own 70% of HomeFed’s common stock; however, our voting rights are limited such that we are not able to vote more than 45% of HomeFed’s total voting securities voting on any matter. Resulting from a 1998 distribution to all of our shareholders, about 4.8% of HomeFed is beneficially owned by our Chairman at December 31, 2017. Three of our executives serve on the board of directors of HomeFed, including our Chairman who serves as HomeFed’s Chairman, and our President.

At December 31, 2017, our investment had a net book value of $310.3 million and we report HomeFed as an equity investment in our financial statements. HomeFed’s strategic priorities vary by project, ranging from pursuing further planning, entitlement and approval, to beginning construction, commencing sales, oversight and management of operating assets, and taking other steps to maximize profits. HomeFed also continues to look for new opportunities both within, and outside of, the areas where it currently has projects under development.

FXCM

FXCM Group, LLC ("FXCM") is a provider of online foreign exchange trading, contract for difference trading, spread betting and related services. Its mission is to provide global traders with access to the world's largest and most liquid market by offering innovative trading tools, hiring excellent trading educators, meeting strict financial standards and striving for the best online trading experience in the market.

During 2015, we invested $279.0 million in FXCM through a combination of a term loan and rights to certain future distributions. Amendments during 2016 and 2017 extended the repayment date of the remaining loan balance to January 2019 and exchanged our rights for a 50% voting interest in FXCM and up to 75% of all distributions. Through these amendments, we also gained the right to appoint three of the six board members of FXCM and, with these board seats, now have significant influence over the operating and financial policies of FXCM. We have the right, as does Global Brokerage Holdings, LLC (“Global Brokerage Holdings”), the owner of the remaining 50% voting interest of FXCM that is not held by Leucadia, to require a sale of FXCM beginning in January 2018. Distributions to Leucadia under the amended agreements are currently: 100% until amounts due under the loan are repaid; 50% of the next $350 million; then 90% of the next $600 million; and 60% of all amounts thereafter.

During February 2017, Global Brokerage Holdings and FXCM's U.S. subsidiary, Forex Capital Markets LLC ("FXCM U.S.") settled complaints filed by the NFA and the CFTC against FXCM U.S. and certain of its principals relating to matters that occurred between 2010 and 2014. As part of the settlements, FXCM U.S. withdrew from business and sold FXCM U.S.'s customer accounts. FXCM also implemented a restructuring plan that included the termination of approximately 22% of its global workforce. The proceeds from the sale of the U.S. accounts, net of closure and severance costs, as well as regulatory capital released after the sale, has been used to pay down the Leucadia term loan.

Through December 31, 2017, we have received cumulatively $331.6 million of principal, interest and fees from our initial $279.0 million investment in FXCM. At December 31, 2017, the remaining principal due under the term loan was $69.9 million and the interest rate is 20.5%. We include this loan receivable in our Consolidated Statements of Financial Condition in Trading assets at its fair value of $72.8 million. Our 50% voting interest and share of distributions are reflected as an equity method investment and classified as Loans to and investments in associated companies, utilizing a one month lag. At December 31, 2017, our equity method investment is recorded at $158.9 million, and the total amount of both our term loan and equity method investment is $231.7 million.

Foursight Capital

In 2012, we partnered with an experienced management team in the indirect auto finance market to start Foursight Capital, of which we own 100%. Foursight Capital purchases automobile installment contracts originated by franchised and independent dealerships in conjunction with the sale of new and used automobiles and services these loans throughout the life cycle. In 2017, Foursight originated $286.5 million in auto loans, up from $250.0 million in 2016. Additionally, Foursight Capital is managing

7

the wind down of the Chrome Capital portfolio. The net book value of our investment in Foursight Capital was $81.8 million at December 31, 2017.

Merchant Banking

The following provides more information about certain of our other subsidiaries and investments and our ownership percentages, including:

• National Beef, 79% (beef processing);

• HRG, 23% (consumer products);

• Garcadia, about 75% (50% voting) (automobile dealerships);

• Linkem, 53% fully-diluted (48% voting) (fixed wireless broadband services);

• JETX Energy, 98% (oil and gas production and development);

• Idaho Timber, 100% (manufacturing); and

• Golden Queen, 35% (a gold and silver mining project).

National Beef

National Beef is one of the largest beef processing companies in the U.S., accounting for approximately 12.5% of the fed cattle slaughter market. National Beef processes and markets fresh and chilled boxed beef, ground beef, beef by-products, consumer-ready beef and pork, and wet blue leather for domestic and international markets. Based in Kansas City, Missouri, National Beef had approximately 8,200 employees at December 31, 2017 and generated total revenues of $7.4 billion in 2017. We purchased National Beef in 2011 and own 78.9%.

The largest share of National Beef’s revenue, about 92.7%, is generated from the sale of boxed beef and beef by-products. National Beef also generates revenues through value-added production with its consumer-ready products. In addition, National Beef operates one of the largest wet blue tanning facilities in the world (wet blue tanning refers to the first step in processing raw and brine-cured hides into tanned leather), selling processed hides to tanners that produce finished leather for the automotive, luxury goods, apparel and furniture industries. Other streams of revenue include sales through its subsidiary, Kansas City Steak Company, LLC, which sells portioned beef and other products directly to consumers through internet, direct mail and direct response television, and service revenues generated by National Carriers, Inc., a wholly owned transportation and logistics company that is one of the largest refrigerated and livestock carrier operations in the U.S. and transports products for National Beef and a variety of other customers. National Beef’s profitability typically fluctuates seasonally as well as cyclically, based on the availability of fed cattle.

The net book value of our investment in National Beef was $517.1 million at December 31, 2017.

Sales and Marketing

National Beef markets its products to national and regional retailers, including supermarket chains, independent grocers, club stores, wholesalers and distributors, food service providers and further processors. In addition, National Beef sells beef by-products to the medical, feed processing, fertilizer and pet food industries. National Beef exports products to more than 20 countries; in 2017, export sales represented approximately 11.2% of revenues. The demand for beef is generally strongest in the spring and summer months and generally decreases during the winter months.

National Beef emphasizes the sale of higher-margin, value-added products, which include branded boxed beef, consumer-ready beef and pork, portion control beef and wet blue hides. National Beef believes its value-added products can command higher prices than commodity products because of National Beef’s ability to consistently meet product specifications, based on quality, trim, weight, size, breed or other factors, tailored to the needs of its customers. In addition to the value-added brands that National Beef owns, National Beef licenses the use of Certified Angus Beef^®, a registered trademark of Certified Angus Beef LLC, and Certified Hereford Beef^®, a registered trademark of Certified Hereford Beef LLC.

Raw Materials and Procurement

The primary raw material for the beef processing plants is live cattle. Live cattle prices change daily based on supply and demand for beef and other proteins, cattle inventory levels, weather and other factors.

National Beef has entered into a cattle supply agreement with U.S. Premium Beef, LLC (“USPB”), the current owner of a 15.1% interest in National Beef, which sold a substantial portion of its ownership interest to us. USPB has agreed to supply, and National

Beef has agreed to purchase through USPB from the members of USPB, 735,385 head of cattle per year (subject to adjustment), based on pricing grids furnished by National Beef to USPB. National Beef believes the pricing grids are based on terms that could be obtained from an unaffiliated party. During 2017, National Beef purchased approximately 24.2% of the total cattle it processed from USPB members pursuant to the cattle supply agreement. National Beef also purchased additional cattle from certain USPB members outside of the cattle supply agreement as well as from hundreds of other cattle suppliers. 

Processing Facilities

National Beef owns two beef processing facilities located in Liberal and Dodge City, Kansas, which can each process approximately 6,000 cattle per day. National Beef’s three consumer-ready processing facilities are in Hummels Wharf, Pennsylvania, Moultrie, Georgia and Kansas City, Kansas. National Beef’s wet blue tanning facility is in St. Joseph, Missouri.

Competition

Competitive conditions exist both in the purchase of live cattle, as well as in the sale of beef products. Beef products compete with other protein sources, including pork and poultry, but National Beef’s principal competition comes from other beef processors.  National Beef believes the principal competitive factors in the beef processing industry are price, quality, food safety, customer service, product distribution, technological innovations (such as food safety interventions and packaging technologies) and brand loyalty. Some of National Beef’s competitors have substantially larger beef operations, greater financial and other resources and wider brand recognition for their products.

Regulation and Environmental

National Beef’s operations are subject to extensive regulation by the U.S. Department of Agriculture ("USDA") including its Food Safety and Inspection Service ("FSIS"), its Animal and Plant Health Inspection Service ("APHIS") and its Grain Inspection, Packers and Stockyards Administration ("GIPSA"), the Food and Drug Administration ("FDA"), the U.S. Environmental Protection Agency ("EPA") and other federal, state, local and foreign authorities regarding the processing, packaging, storage, safety, distribution, advertising and labeling of its products.

National Beef is subject to the Packers and Stockyards Act of 1921 ("PSA"). Among other things, this statute generally requires National Beef to make full payment for livestock purchases not later than the close of business the day after the purchase and transfer of possession or determination of the purchase price. Under the PSA, National Beef must hold in trust for the benefit of unpaid cash livestock suppliers all receivables, inventory and proceeds derived from National Beef's sale of such cattle until the sellers have received full payment. In addition, pursuant to PSA rules, at December 31, 2017, National Beef has obtained from an insurance company a surety bond in the amount of $50.4 million as a measure of protection for livestock sellers.

The Dodge City and Liberal facilities are subject to Title V permitting pursuant to the Federal Clean Air Act and the Kansas Air Quality Act. The St. Joseph facility is subject to a secondary air permit which is in place. The Dodge City, Liberal, Hummels Wharf and Moultrie facilities are subject to Clean Air Act Risk Management Plan requirements relating to the use of ammonia as a refrigerant.

All of National Beef’s plants are indirect dischargers of wastewater to publicly owned treatment works and are subject to requirements under the federal Clean Water Act, state and municipal laws, as well as agreements or permits with municipal or county authorities. Upon renewal of these agreements and permits, National Beef is from time to time required to make capital expenditures to upgrade or expand wastewater treatment facilities to address new and more stringent discharge requirements imposed at the time of renewal. Storm water discharges from National Beef’s plants are also regulated by state and local authorities.

All of National Beef’s facilities generate solid waste streams including small quantities of hazardous wastes. National Beef is subject to laws that provide for strict, and in certain circumstances, joint and several liability for remediation of hazardous substances at contaminated sites; however, National Beef has not received any demands that it has any liability at sites under the Comprehensive Environmental Response, Compensation and Liability Act (“Superfund”) or state counterparts. All plants are subject to community right to know reporting requirements under the Superfund Amendments and Reauthorization Act of 1986, which requires yearly filings as to the substances used on facility premises.

Employees

Of National Beef’s 8,200 employees, approximately 5,200 are represented by collective bargaining agreements. Approximately 2,500 employees at the Liberal plant are represented by the United Food and Commercial Workers International Union under a collective bargaining agreement scheduled to expire in December 2022, approximately 2,500 employees at the Dodge City plant are represented by the United Food and Commercial Workers International Union under a collective bargaining agreement scheduled to expire in December 2021, and another approximately 200 employees at the St. Joseph plant are represented by the United Cereal Workers (R.W.D.S.U./U.F.C.W.) under a collective bargaining agreement scheduled to expire in June 2019.

HRG Group

HRG Group, Inc. ("HRG") is a publicly traded (NYSE: HRG) holding company that primarily owns approximately 59% of Spectrum Brands, a publicly traded (NYSE: SPB) global consumer products company. HRG sold its approximate 80% interest in Fidelity & Guaranty Life, a life insurance and annuity products company and 100% interest in Front Street, a long-term reinsurance company, to CF Corporation in the fourth quarter of 2017. HRG continues to streamline its business and simplify its holding company structure and has announced that they are exploring strategic alternatives to maximize shareholder value. These strategic alternatives may include a merger, sale or business combination involving HRG and Spectrum Brands.

As of December 31, 2017, we own 46.6 million common shares of HRG, representing about 23% of its outstanding common shares, which we reflect in our financial results at fair value. In addition, we currently have two directors on HRG’s board, including our Chairman who serves as HRG's Chairman and CEO. At December 31, 2017, the book value of our holdings in HRG is $789.9 million and our cost was $475.6 million.

Garcadia

Garcadia is a joint venture between us and Garff Enterprises, Inc. ("Garff"), which is owned by members of a family that has operated car dealerships for over 85 years. Garcadia owns and operates 28 domestic and foreign automobile dealerships in California, Iowa, Texas and Michigan. We and Garff have equal board representation and equal votes on all matters affecting Garcadia, and all operating cash flows from Garcadia are allocated 65% to us and 35% to Garff, with the exception of one dealership from which we receive 83% of all operating cash flows and four other dealerships from which we receive 71% of all operating cash flows. Garcadia’s strategy is to own and operate automobile dealerships in primary or secondary market locations meeting its specified return criteria. During 2017, we received cash distributions from Garcadia's dealerships of $45.3 million.

In addition, we own parcels of land that are leased to certain dealerships. During 2017, we received rent payments related to these leases of $9.5 million. At December 31, 2017, the net book value of our investment in Garcadia was $179.1 million and our net investment in the parcels of land leased to the dealerships was $20.4 million, net of $53.4 million in mortgage debt.

Linkem

Linkem S.p.A. is a fixed wireless broadband service provider in Italy. Unlike the U.S. and most of Western Europe, Italy does not have a national cable television system; as a result, Italy’s broadband penetration rate is among the lowest in Europe. Linkem offers residential broadband services using LTE technologies deployed over the 3.5 GHz spectrum band. 

Our initial investment in Linkem was made in July 2011. Since that time, we have funded much of Linkem’s growth and become its largest shareholder. We own approximately 42% of the common shares of Linkem, as well as convertible preferred shares which, if converted, would increase our ownership to approximately 53% of Linkem's common equity at December 31, 2017. We have approximately 48% of the total voting securities of Linkem.

Linkem owns or has exclusive rights to spectrum holdings of 84MHz covering over 80% of the population of Italy and at least 42MHz covering all of Italy. At December 31, 2017, Linkem’s network includes base stations deployed on 2,339 wireless towers that can reach 65% of Italian households. Linkem has over 500,000 subscribers for its services. Linkem's base stations are now all LTE-enabled. LTE provides subscribers with faster download speeds and improved service compared to DSL, the most popular broadband alternative. Linkem plans to increase its network coverage across Italy over the coming years as it adds subscribers and it is exploring wholesale arrangements with existing operators who would white label Linkem's services. Expansion and customer acquisition costs are expected to result in operating losses over the next couple of years. 

Through December 31, 2017, we had invested $323.9 million in Linkem and the net book value of our investment was $192.1 million at December 31, 2017.

Oil and Gas

Vitesse Energy, LLC ("Vitesse") is a non-operating owner of oil and gas properties in the core of the Bakken Shale oil field in North Dakota and Montana and the Denver-Julesburg Basin in Wyoming. We own 96% of Vitesse, which acquires producing and undeveloped leasehold properties. Vitesse participates with its operating partners in the drilling and completion of lower risk new horizontal wells on our leaseholds acreage, which converts our leasehold into cash flow producing assets. Vitesse has acquired approximately 20,600 net acres of Bakken leasehold and has an interest in 1,572 producing wells (42 net wells) and 467 gross wells (13 net wells) that are currently drilling, completing or permitted for drilling. In 2016, Vitesse acquired interests in 31 wellbores, which were drilled but not yet completed, in the Denver-Julesburg Basin. As of December 31, 2017, 26 of those wellbores have been completed. Our strategic priorities for Vitesse are to selectively add to our core acreage, participate in future profitable horizontal wells, increase aggregate cash flow, and profitably sell selective assets when appropriate.

We also own 98% of JETX Energy, LLC ("JETX"), formerly Juneau Energy, LLC, which currently has acreage and producing wells primarily in Brazos and Grimes counties in East Texas. During 2016, the management of JETX was transferred to the Vitesse team and the company is now pursuing a non-operating strategy, whereby JETX has partnered with Lonestar Resources US Inc. (NASDAQ: LONE) ("Lonestar"), an accomplished Eagle Ford operator. In August 2016, JETX sold 50% of its interest in its two East Eagle Ford wells that JETX drilled and completed in late 2015 to Lonestar for equity and interests in Lonestar's nearby oil and gas properties. Lonestar also agreed to pool some of its nearby acreage with JETX's and will pursue development of the pooled acreage. In addition, JETX invested $25 million in Lonestar in exchange for $25 million principal amount of secured second lien notes and warrants. In December 2016, Lonestar repurchased $21 million principal amount of these secured second lien notes and in January 2017, JETX sold the remaining $4 million to a third party. Lonestar successfully drilled and completed one of the better wells in the Eastern Eagle Ford when the Wildcat B1H well was brought on line in May 2017. JETX has a 50% interest in the well and the undeveloped drilling locations within the unit. JETX's strategic priorities include the further development of our acreage in the East Eagle Ford, partnering with additional proven operators in JETX's leasehold and selectively selling assets.

At December 31, 2017, we have made cumulative net cash investments of $564.5 million in Vitesse and JETX and the net book value of our oil and gas investments is $416.6 million. 

Idaho Timber

Idaho Timber manufactures and distributes an extensive range of quality wood products to markets across North America. Its activities include remanufacturing dimension lumber; remanufacturing, bundling and bar coding of home center boards for large retailers; and production of pine dimension lumber and 5/4” radius-edge, pine decking. In addition to its headquarters in Meridian, Idaho, Idaho Timber has plants in Idaho, Arkansas, Florida, Louisiana, New Mexico, North Carolina and Texas.

The net book value of our investment was $81.5 million at December 31, 2017.

Golden Queen Mining Company

Golden Queen is a joint venture between Golden Queen Mining Co., Ltd. (“GQM”) and Gauss LLC ("Gauss"). We own 70% of Gauss, which in turn owns 50% of the joint venture, giving us an effective 35% interest in Golden Queen.

Item 1A. Risk Factors.

Our business is subject to a number of risks. You should carefully consider the following risk factors, together with all of the other information included or incorporated by reference in this report, before you decide whether to purchase our securities. The risks set out below are not the only risks we face. In addition to the specific risks mentioned in this report, we may also be affected by other factors that affect businesses generally such as global or regional changes in economic, business or political conditions, acts of war, terrorism or natural disasters. If any of such risks occur, our business, financial condition and results of operations could be materially adversely affected. In such case, the trading price of our securities could decline, and you may lose all or part of your investment.

Future acquisitions and dispositions of our businesses and investments are possible, changing the components of our assets and liabilities, and if unsuccessful or unfavorable, could reduce the value of our securities. Any future acquisitions or dispositions may result in significant changes in the composition of our assets and liabilities, as well as our business mix and prospects. Consequently, our financial condition, results of operations and the trading price of our securities may be affected by factors different from those affecting our financial condition, results of operations and trading price at the present time.

We face numerous risks and uncertainties as we expand our business. We expect the growth and development of our business to come primarily from internal expansion and through acquisitions, investments, and strategic partnering. As we expand our business, there can be no assurance that financial controls, the level and knowledge of personnel, operational abilities, legal and compliance controls and other corporate support systems will be adequate to manage our business and growth. The ineffectiveness of any of these controls or systems could adversely affect our business and prospects. In addition, if we acquire new businesses and introduce new products, we face numerous risks and uncertainties integrating their controls and systems, including financial controls, accounting and data processing systems, management controls and other operations. A failure to integrate these systems and controls, and even an inefficient integration of these systems and controls, could adversely affect our business and prospects.

Certain business initiatives, including expansions of existing businesses, may bring us into contact directly or indirectly, with individuals and entities that are not within our traditional client and counterparty base and may expose us to new asset classes and new markets. These business activities expose us to new and enhanced risks, greater regulatory scrutiny of these activities, increased credit-related, sovereign and operational risks, and reputational concerns regarding the manner in which these assets are being operated or held.

Our business, financial condition and results of operations are dependent upon those of our individual businesses, and our aggregate investment in particular industries. We are a holding company with investments in businesses and assets in a number of industries. Jefferies is our largest investment and we have significant additional investments in the financial services industry.  Our business, financial condition and results of operations are dependent upon our various businesses and investments. Any material

12

adverse change in one of our businesses or investments, or in a particular industry in which we operate or invest, may cause material adverse changes to our business, financial condition and results of operations. The more capital we devote to a particular investment or industry may increase the risk that such investment could significantly impact our financial condition and results of operations, possibly in a material adverse way.

Conditions in the financial markets and the economy may adversely impact our businesses and investments. These include economic conditions that may be specific to the industries in which our businesses and investments operate, as well as a general economic slowdown, prolonged recession or other market downturn or disruption. Adverse impacts may include the following:

• A market downturn could lead to a decline in client and customer activity levels, and therefore a decline in services provided, causing reduced revenues from fees, commissions, spreads and other forms of revenue.

• Adverse changes in the market could lead to decreases in the value of our holdings, both realized and unrealized.

• Adverse changes in the market could also lead to a reduction in revenues from asset management fees and investment income from managed funds. The build out of our asset management business could also be impacted as adverse conditions could lead to a decrease in new capital raised and may cause investors to withdraw their investments and commitments. Even in the absence of a market downturn, below-market investment performance by funds and portfolio managers could reduce asset management revenues and assets under management and result in reputational damage that might make it more difficult to attract new investors.

• Limitations on the availability of credit, such as occurred during 2008, can affect the ability of our businesses and investments to borrow on a secured or unsecured basis, which may adversely affect liquidity and results of operations. Global market and economic conditions have been particularly disrupted and volatile in the last several years and may be in the future. Cost and availability of funding could be affected by illiquid credit markets and wider credit spreads.

• Changes in tax law could impact our ability to utilize our deferred tax assets, decrease current and anticipated cash flows, or prompt revisions to compensation arrangements.

• Should one or more of the competitors of our businesses or investments fail, business prospects and revenue could be negatively impacted due to negative market sentiment causing customers to cease doing business with, and lenders to cease extending credit to, our businesses and investments, which could adversely affect our operations, funding and liquidity.

• Unfavorable economic conditions could have an adverse effect on the demand for new loans and the servicing of loans originated by third parties, which would have an adverse impact on the operations and profitability of some of our financial services businesses and investments.

The United Kingdom's exit from the European Union could adversely affect our businesses and investments. The referendum held in the U.K. on June 23, 2016 resulted in a determination that the U.K. should exit the European Union. In March 2017, the U.K. government initiated the exit process under Article 50 of the Treaty of the EU, commencing a period of up to two years for the United Kingdom and the other EU member states to negotiate the terms of the withdrawal. The uncertainty surrounding the timing, terms and consequences of the U.K.’s exit could adversely impact customer and investor confidence, result in additional market volatility, and adversely affect Jefferies, FXCM, as well as certain of HRG's subsidiaries, particularly those with operations or customers in Europe.

Jefferies operates substantial parts of its EU businesses from entities based in the U.K. Upon the U.K. leaving the EU, the regulatory and legal environment that would then exist, and to which its U.K. operations would then be subject, will depend on, in certain respects, the nature of the arrangements the U.K. agreed with the EU and other trading partners. It is highly likely that changes to its legal entity structure and operations in Europe will be required as a result of these arrangements, which might result in a less efficient operating model across its European legal entities. Jefferies is in the process of finalizing plans to ensure its continued ability to operate in the U.K. and the EU beyond the expected exit date.

Damage to our reputation could damage our business. Maintaining our reputation is critical to our attracting and maintaining customers, investors and employees. If we fail to deal with, or appear to fail to deal with, various issues that may give rise to reputational risk, we could significantly harm our business prospects. These issues include, but are not limited to, any of the risks discussed in this Item 1A, appropriately dealing with potential conflicts of interest, legal and regulatory requirements, ethical issues, money-laundering, cybersecurity and privacy, record keeping, sales and trading practices, failure to sell securities we have underwritten at the anticipated price levels, and the proper identification of the legal, reputational, credit, liquidity and market risks inherent in our products. A failure to deliver appropriate standards of service and quality, or a failure or perceived failure to treat customers and clients fairly, can result in customer dissatisfaction, litigation and heightened regulatory scrutiny, all of which can lead to lost revenue, higher operating costs and harm to our reputation. Further, negative publicity regarding us, whether or not true, may also result in harm to our prospects. Our operations in the past have been impacted as some clients either ceased doing business or temporarily slowed down the level of business they do, thereby decreasing our revenue. There is no assurance

13

that we will be able to successfully reverse the negative impact of allegations and rumors in the future and our potential failure to do so could have a material adverse effect on our business, financial condition and liquidity.

Jefferies and LAM may incur losses if their risk management is not effective. Jefferies and LAM seek to monitor and control their risk exposure. Their risk management processes and procedures are designed to limit their exposure to acceptable levels as they conduct their businesses. Jefferies applies a comprehensive framework of limits on a variety of key metrics to constrain the risk profile of its business activities. The size of the limit reflects Jefferies’ risk tolerance for a certain activity. The framework includes inventory position and exposure limits on a gross and net basis, scenario analysis and stress tests, value-at-risk, sensitivities, exposure concentrations, aged inventory, amount of Level 3 assets, counterparty exposure, leverage, cash capital, and performance analysis. While Jefferies and LAM employ various risk monitoring and risk mitigation techniques, those techniques and the judgments that accompany their application, including risk tolerance determinations, cannot anticipate every economic and financial outcome or the specifics and timing of such outcomes. As a result, Jefferies and LAM may incur losses notwithstanding their risk management processes and procedures.

Recent legislation and new and pending regulation may significantly affect Jefferies or our other businesses and investments.  In recent years, there has been significant legislation and increased regulation affecting the financial services industry. In addition, there has also been recent discussions of proposed legislative and regulatory changes that would also affect the financial services industry. These legislative and regulatory initiatives affect not only Jefferies, LAM, FXCM, and Berkadia, but also their competitors and certain of their clients and customers. These changes could have an effect on our revenue and profitability, limit our ability to pursue certain business opportunities, impact the value of assets that we hold, require us to change certain business practices, impose additional costs on us and otherwise adversely affect our business. Accordingly, we cannot provide assurance that legislation and regulation will not eventually have an adverse effect on our business, results of operations, cash flows and financial condition.

Extensive regulation of Jefferies and LAM business limits their activities, and, if Jefferies or LAM violates these regulations, they may be subject to significant penalties. The financial services industry is subject to extensive laws, rules and regulations in every country in which Jefferies and LAM operates. Firms that engage in securities and derivatives trading, wealth and asset management and investment banking must comply with the laws, rules and regulations imposed by national and state governments and regulatory and self-regulatory bodies with jurisdiction over such activities. Such laws, rules and regulations cover all aspects of the financial services business, including, but not limited to, sales and trading methods, trade practices, use and safekeeping of customers’ funds and securities, capital structure, anti-money laundering and anti-bribery and corruption efforts, recordkeeping and the conduct of directors, officers and employees.

Each of Jefferies and LAM regulators supervises their business activities to monitor compliance with such laws, rules and regulations in the relevant jurisdiction. In addition, if there are instances in which Jefferies or LAM regulators question their compliance with laws, rules, and regulations, they may investigate the facts and circumstances to determine whether Jefferies or LAM have complied. At any moment in time, Jefferies or LAM may be subject to one or more such investigation or similar reviews. At this time, all such investigations and similar reviews are insignificant in scope and immaterial to Jefferies and LAM. However, there can be no assurance that, in the future, the operations of Jefferies or LAM businesses will not violate such laws, rules, or regulations and such investigations and similar reviews will not result in adverse regulatory requirements, regulatory enforcement actions and/or fines.

Any violation of these laws, rules and regulations could subject Jefferies or LAM to one or more of the following events: civil and criminal liability; sanctions, which could include the revocation of its subsidiaries' registrations as registered investment advisors or broker-dealers; the revocation of the licenses of its financial advisors; censures; fines; or a temporary suspension or permanent bar from conducting business. The occurrence of any of these events could have a material adverse effect on Jefferies or LAM business, financial condition and prospects.

Certain of Jefferies' subsidiaries are subject to regulatory financial capital holding requirements, such as the Net Capital Rule, that could impact various capital allocation decisions or limit the operations of its broker-dealers. In particular, compliance with the Net Capital Rule may restrict its broker-dealers' ability to engage in capital-intensive activities such as underwriting and trading, and may also limit their ability to make loans, advances, dividends and other payments.

Additional legislation, changes in rules, changes in the interpretation or enforcement of existing laws and rules, conflicts and inconsistencies among rules and regulations, or the entering into businesses that subject Jefferies or LAM to new rules and regulations may directly affect their business, results of operations and financial condition. Jefferies and LAM continue to monitor the impact of new U.S. and international regulation on their businesses.

A credit rating agency downgrade could significantly impact our businesses. We and Jefferieshave credit ratings issued by various credit rating agencies. Maintaining our credit ratings is important to our and Jefferies business and financial condition. 

14

We advised certain credit rating agencies that we would target specific concentration, leverage and liquidity principles, expressed in the form of certain ratios and percentages. A failure to meet these ratios and percentages could trigger a ratings downgrade. We and Jefferies intend to access capital markets and issue debt securities from time to time, and a ratings downgrade may decrease demand for such offered security. A decrease in demand would not only make a successful financing more difficult, but also increase our respective capital costs. Similarly, our and Jefferies access to other forms of credit may be limited and our respective borrowing costs may increase if our or Jefferies credit ratings are downgraded. A downgrade could also negatively impact our and Jefferies outstanding debt prices and our stock price. In addition, in connection with certain over-the-counter derivative contract arrangements and certain other trading arrangements, a ratings downgrade could cause us or Jefferies to provide additional collateral to counterparties, exchanges and clearing organizations which would negatively impact our and Jefferies liquidity and financial condition. There can be no assurance that our or Jefferies credit ratings will not be downgraded.

In addition, if Berkadia does not maintain specified servicer ratings from the credit rating agencies, customers would have the right to terminate their mortgage servicing agreements. If mortgage servicing agreements were terminated as a result of a servicer ratings downgrade, we could lose a significant portion of the value of our equity investment.

Jefferies principal trading and investments expose us to risk of loss. A considerable portion of Jefferies revenues is derived from trading in which Jefferies acts as principal. Jefferies may incur trading losses relating to the purchase, sale or short sale of fixed income, high yield, international, convertible, and equity securities, loans and futures and commodities for its own account. In any period, Jefferies may experience losses on its inventory positions as a result of price fluctuations, lack of trading volume, and illiquidity.  From time to time, Jefferies may engage in a large block trade in a single security or maintain large position concentrations in a single security, securities of a single issuer, securities of issuers engaged in a specific industry, or securities from issuers located in a particular country or region. In general, because Jefferies inventory is marked to market on a daily basis, any adverse price movement in these securities could result in a reduction of Jefferies revenues and profits. In addition, Jefferies may engage in hedging transactions that if not successful, could result in losses.

We are exposed to market risk. We are, directly and indirectly, affected by changes in market conditions. Market risk generally represents the risk that values of assets and liabilities or revenues will be adversely affected by changes in market conditions. For example, changes in interest rates could adversely affect our net interest spread, the difference between the yield we earn on our assets and the interest rate we pay for sources of funding, which, in turn, impacts our net interest revenue and earnings. Changes in interest rates could affect the interest earned on assets differently than interest paid on liabilities. In our brokerage operations, a rising interest rate environment generally results in our earning a larger net interest spread. Conversely, in those operations, a falling interest rate environment generally results in our earning a smaller net interest spread. If we are unable to effectively manage our interest rate risk, changes in interest rates could have a material adverse effect on our profitability.

Market risk is inherent in the financial instruments associated with our operations and activities, including trading account assets and liabilities, loans, securities, short-term borrowings, corporate debt, and derivatives. Market conditions that change from time to time, thereby exposing us to market risk, include fluctuations in interest rates, equity prices, relative exchange rates, and price deterioration or changes in value due to changes in market perception or actual credit quality of an issuer.

In addition, disruptions in the liquidity or transparency of the financial markets may result in our inability to sell, syndicate, or realize the value of security positions, thereby leading to increased concentrations. The inability to reduce our positions in specific securities may not only increase the market and credit risks associated with such positions, but also increase the level of risk-weighted assets on our balance sheet, thereby increasing capital requirements, which could have an adverse effect on our business, results of operations, financial condition and liquidity.

Increased competition may adversely affect Jefferies revenues and profitability. All aspects of Jefferies business are intensely competitive. Jefferies competes directly with a number of bank holding companies and commercial banks, other brokers and dealers, investment banking firms and other financial institutions. In addition to competition from firms currently in the securities business, there has been increasing competition from others offering financial services, including automated trading and other services based on technological innovations. Jefferies believes that the principal factors affecting competition involve market focus, reputation, the abilities of professional personnel, the ability to execute the transaction, relative price of the service and products being offered, bundling of products and services and the quality of products and service. Increased competition or an adverse change in Jefferies competitive position could lead to a reduction of business and therefore a reduction of revenues and profits.

The ability to attract, develop and retain highly skilled and productive employees is critical to the success of our business. Our ability to develop and retain our clients depends on the reputation, judgment, business generation capabilities and skills of our professionals. To compete effectively, we must attract, retain and motivate qualified professionals, including successful financial advisors, investment bankers, trading professionals, portfolio managers and other revenue producing or specialized personnel.

15

Competitive pressures we experience with respect to employees could have an adverse effect on our business, results of operations, financial condition and liquidity.

Turnover in the financial services industry is high. The cost of retaining skilled professionals in the financial services industry has escalated considerably. Financial industry employers are increasingly offering guaranteed contracts, upfront payments, and increased compensation. These can be important factors in a current employee's decision to leave us as well as in a prospective employee's decision to join us. As competition for skilled professionals in the industry remains intense, we may have to devote significant resources to attracting and retaining qualified personnel.

If we were to lose the services of certain of our professionals, we may not be able to retain valuable relationships and some of our clients could choose to use the services of a competitor instead of our services. If we are unable to retain our professionals or recruit additional professionals, our reputation, business, results of operations and financial condition will be adversely affected. Further, new business initiatives and efforts to expand existing businesses frequently require that we incur compensation and benefits expense before generating additional revenues.

Moreover, companies in our industries whose employees accept positions with competitors often claim that those competitors have engaged in unfair hiring practices. We may be subject to such claims in the future as we seek to hire qualified personnel who have worked for our competitors. Some of these claims may result in material litigation. We could incur substantial costs in defending against these claims, regardless of their merits. Such claims could also discourage potential employees who work for our competitors from joining us.

Operational risks may disrupt Jefferies business, result in regulatory action against Jefferies or limit Jefferies growth. Jefferies businesses are highly dependent on its ability to process, on a daily basis, a large number of transactions across numerous and diverse markets in many currencies, and the transactions Jefferies processes have become increasingly complex. If any of Jefferies financial, accounting or other data processing systems do not operate properly or are disabled or if there are other shortcomings or failures in Jefferies internal processes, people or systems, Jefferies could suffer an impairment to its liquidity, financial loss, a disruption of its businesses, liability to clients, regulatory intervention or reputational damage. These systems may fail to operate properly or become disabled as a result of events that are wholly or partially beyond Jefferies control, including a disruption of electrical or communications services or Jefferies inability to occupy one or more of its buildings. The inability of Jefferies systems to accommodate an increasing volume of transactions could also constrain its ability to expand its businesses.

Certain of Jefferies financial and other data processing systems rely on access to and the functionality of operating systems maintained by third parties. If the accounting, trading or other data processing systems on which Jefferies is dependent are unable to meet increasingly demanding standards for processing and security or, if they fail or have other significant shortcomings, Jefferies could be adversely affected. Such consequences may include Jefferies inability to effect transactions and manage Jefferies exposure to risk.

In addition, despite the contingency plans Jefferies has in place, Jefferies ability to conduct business may be adversely impacted by a disruption in the infrastructure that supports its businesses and the communities in which they are located. This may include a disruption involving electrical, communications, transportation or other services used by Jefferies or third parties with which Jefferies conducts business.

Jefferies information and technology systems are critical components of its business and operations, and a failure of those systems or other aspects of its operations infrastructure may disrupt its business, cause financial loss, increase its legal liability and constrain its growth. Jefferies operations rely extensively on the secure processing, storage and transmission of confidential and other information in Jefferies computer systems and networks. Although Jefferies takes protective measures and devotes significant resources to maintaining and upgrading its systems and networks with measures such as intrusion and detection prevention systems, monitoring firewall to safeguard critical business applications and supervising third party providers that have access to its systems, Jefferies computer systems, software and networks may be vulnerable to unauthorized access, computer viruses or other malicious code, and other events that could have a security impact. Additionally, if a client’s computer system, network or other technology is compromised by unauthorized access, Jefferies may face losses or other adverse consequences by unknowingly entering into unauthorized transactions. If one or more of such events occur, this potentially could jeopardize Jefferies or its clients’ or counterparties’ confidential and other information processed and stored in and transmitted through our computer systems and networks. Furthermore, such events may cause interruptions or malfunctions in Jefferies, its clients’, its counterparties’ or third parties’ operations, including the transmission and execution of unauthorized transactions. Jefferies may be required to expend significant additional resources to modify its protective measures or to investigate and remediate vulnerabilities or other exposures, and Jefferies may be subject to litigation and financial losses that are either not covered or not fully covered through any insurance maintained by Jefferies. The increased use of smartphones, tablets and other mobile devices as well as cloud computing may also heighten these and other operational risks. Similar to other firms, Jefferies and its third party providers continue

16

to be the subject of attempted unauthorized access, computer viruses and malware, and cyber attacks designed to disrupt or degrade service or cause other damage and denial of service. Additional challenges are posed by external parties, including foreign state actors. There can be no assurance that such unauthorized access or cyber incidents will not occur in the future, and they could occur more frequently and on a larger scale.

Jefferies is also subject to laws and regulations relating to the privacy of the information of its clients, employees or others, and any failure to comply with these regulations could expose Jefferies to liability and/or reputational damage. In addition, Jefferies' businesses are increasingly subject to laws and regulations relating to surveillance, encryption and data on-shoring in the jurisdictions in which it operates. Compliance with these laws and regulations may require Jefferies to change its policies, procedures and technology for information security, which could, among other things, make Jefferies more vulnerable to cyber attacks and misappropriation, corruption or loss of information or technology.

Jefferies business is subject to significant credit risk. In the normal course of Jefferies businesses, Jefferies is involved in the execution, settlement and financing of various customer and principal securities and derivative transactions. These activities are transacted on a cash, margin or delivery-versus-payment basis and are subject to the risk of counterparty or customer nonperformance. Although transactions are generally collateralized by the underlying security or other securities, Jefferies still faces the risks associated with changes in the market value of the collateral through settlement date or during the time when margin is extended and collateral has not been secured or the counterparty defaults before collateral or margin can be adjusted. Jefferies may also incur credit risk in its derivative transactions to the extent such transactions result in uncollateralized credit exposure to counterparties.

Jefferies seeks to control the risk associated with these transactions by establishing and monitoring credit limits and by monitoring collateral and transaction levels daily. Jefferies may require counterparties to deposit additional collateral or return collateral pledged. In certain circumstances, Jefferies may, under industry regulations, purchase the underlying securities in the market and seek reimbursement for any losses from the counterparty. However, there can be no assurances that Jefferies risk controls will be successful.

The prices and availability of key raw materials affects the profitability of our beef processing and manufacturing operations.  The supply and market price of cattle purchased by National Beef are dependent upon a variety of factors over which National Beef has no control, including fluctuations in the size of herds maintained by producers, the relative cost of feed and energy, weather and livestock diseases. The cost of raw materials used by our manufacturing businesses have fluctuated over time as a result of a variety of factors. Although our manufacturing businesses are not currently experiencing any shortage of raw materials, if such shortages occur, revenues and profitability could decline.

Outbreaks of disease affecting livestock can adversely affect the supply of cattle and the demand for National Beef’s products.  National Beef is subject to risks relating to animal health and disease control. An outbreak of disease affecting livestock (such as foot-and-mouth disease or bovine spongiform encephalopathy (“BSE”), commonly referred to as mad cow disease) could result in restrictions on sales of products, restrictions on purchases of livestock from suppliers or widespread destruction of cattle. The discovery of BSE in the past caused certain countries to restrict or prohibit the importation of beef products. Outbreaks of diseases, or the perception by the public that an outbreak has occurred, or other concerns regarding diseases, can lead to inadequate supply, cancellation of orders by customers and create adverse publicity, any of which can have a significant negative impact on consumer demand and, as a result, on our consolidated financial position, cash flows and results of operations.

If National Beef’s products or products made by others using its products become contaminated or are alleged to be contaminated, National Beef may be subject to product liability claims that could adversely affect its business. National Beef may be subject to significant liability in excess of insurance policy limits if its products or products made by others using its products cause injury, illness or death. In addition, National Beef could recall or be required to recall products that are, or are alleged to be, contaminated, spoiled or inappropriately labeled. Organisms producing food borne illnesses (such as E. coli) could be present in National Beef’s products and result in illness or death if they are not eliminated through further processing or cooking.  Contamination of National Beef’s or its competitors’ products may create adverse publicity or cause consumers to lose confidence in the safety and quality of beef products. Allegations of product contamination may also be harmful even if they are untrue or result from third-party tampering. Any of these events may increase costs or decrease demand for beef products, any of which could have a significant adverse effect on our consolidated financial condition, cash flows and results of operations.

National Beef generally does not enter into long-term contracts with customers; as a result, the volumes and prices at which beef products are sold are subject to market forces. National Beef’s customers generally place orders for products on an as-needed basis and, as a result, their order levels have varied from period to period in the past and may vary significantly in the future. The loss of one or more significant customers, a significant decline in the volume of orders from customers or a significant decrease in beef product prices for a sustained period of time could negatively impact cash flows and results of operations.

17

National Beef’s exports expose it to political and economic risks in the U.S. and foreign countries, as well as to risks related to currency fluctuations. Approximately 11.2% of National Beef’s annual sales are export sales, primarily to Japan, Mexico, South Korea, Hong Kong, China, Taiwan, Italy and Canada, and on average these sales have a higher margin than domestic sales of similar products. A reduction in international sales could adversely affect revenues and margins. Risks associated with international activities include inflation or deflation and changes in foreign currency exchange rates, including changes in currency exchange rates of other countries that may export beef products in competition with National Beef; the closing of borders by foreign countries to product imports due to disease or other perceived health or food safety issues; exchange controls; changes in tariffs; changes in political or economic conditions; trade restrictions and changes in regulatory requirements. The occurrence of any of these events could increase costs, lower demand for products or limit operations, which could have a significant adverse effect on cash flows, results of operations and future prospects. 

National Beef incurs substantial costs to comply with environmental regulations and could incur additional costs as a result of new regulations or compliance failures that result in civil or criminal penalties, liability for damages and negative publicity.  National Beef’s operations are subject to extensive and stringent environmental regulations administered by the EPA and state, local and other authorities with regards to water usage, wastewater and storm water discharge, air emissions and odor, and waste management and disposal. Failure to comply with these laws and regulations could have serious consequences, including criminal, civil and administrative penalties and negative publicity. In addition, National Beef incurs and will continue to incur significant capital and operating expenditures to comply with existing and new or more stringent regulations and requirements. All of National Beef’s processing facilities procure wastewater treatment services from municipal or other regional governmental agencies that are in turn subject to environmental laws and permit limits regarding their water discharges. As permit limits are becoming more stringent, upgrades and capital improvements to these municipal treatment facilities are likely. In locations where National Beef is a significant volume discharger, it could be asked to contribute toward the costs of such upgrades or to pay significantly increased water or sewer charges to recoup such upgrade costs.  National Beef may also be required to undertake upgrades and make capital improvements to its own wastewater pretreatment facilities, the cost of which could be significant. Compliance with environmental regulations has had and will continue to have a significant impact on National Beef’s cash flows and profitability. In addition, under most environmental laws, most notably the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) and analogous state laws, National Beef could be held liable for the cost to investigate or remediate any contamination at properties it owns or operates, or as to which it arranges for the disposal or treatment of hazardous substances, as such liability is imposed without regard to fault.

National Beef is subject to extensive governmental regulation and noncompliance with or changes in applicable requirements could adversely affect its business, financial condition, cash flows and results of operations. National Beef’s operations are subject to extensive regulation and oversight by the USDA, including its FSIS, APHIS and GIPSA agencies, the FDA, and other federal, state, local and foreign authorities regarding the procurement of cattle and the processing, packaging, storage, safety, distribution, advertising and labeling of its products. Recently, food safety practices and procedures in the meat processing industry have been subject to more intense scrutiny and oversight by the USDA. National Beef is also subject to a variety of immigration, labor and worker safety laws and regulations, including those relating to the hiring and retention of employees. Failure to comply with existing or new laws and regulations could result in administrative penalties and injunctive relief, civil remedies, fines, interruption of operations, recalls of products or seizures of properties, potential criminal sanctions and personal injury or other damage claims.  These remedies, changes in the applicable laws and regulations or discovery of currently unknown conditions could increase costs, limit business operations and reduce profitability.

National Beef’s performance depends on favorable labor relations with its employees, in particular employees represented by collective bargaining agreements. A substantial number of National Beef’s employees are covered by collective bargaining agreements. A labor-related work stoppage by unionized employees, or employees who become unionized in the future, could limit National Beef’s ability to process and ship products or could increase costs. Any significant increase in labor costs, deterioration of employee relations, slowdowns or work stoppages at any of National Beef’s locations, whether due to union activities, employee turnover or otherwise, could have a material adverse effect on our financial condition, cash flows and results of operations.

Uncertainties inherent in HRG’s business and operations could impact the realizability of the full value of our investment. As a holding company, HRG is subject to risks and uncertainties across the industries in which it invests. It is also subject to risks associated with its holding company structure, which include potential difficulties or limitations in receiving distributions from its subsidiaries, and the risk that acquisitions, dispositions or integrations of subsidiaries may not be successful. The overall profitability of HRG is directly contingent on the profitability of its subsidiaries, which are subject to a number of specific risks, including substantial indebtedness and restrictive covenants within Spectrum Brands. We hold about 23% of the common shares of HRG and we record our investment at fair value. As we do not control HRG, its management may make decisions that are not in our best interest. HRG could decide to issue additional common shares, which would dilute our current ownership. Additionally,

18

changes in the market price of HRG shares may lead to volatility in our results of operations. For additional risk factors concerning HRG, see its SEC filings.

Uncertainties relating to the results of FXCM could impact the value of our investment in FXCM. FXCM’s revenue and operating results may vary significantly from period to period due to movements and trends in the world’s currency markets and to fluctuations in trading levels. In addition, attrition of customer accounts, which are primarily comprised of individual retail customers, and failure to attract new accounts could impact revenue and profitability. FXCM is also subject to regulatory risks, as well as risks such as those relating to government actions like the unexpected actions of the Swiss National Bank on January 15, 2015, which resulted in the historic movement in the Swiss Franc.

The performance of our oil and gas production and development investments, JETX and Vitesse, is impacted by uncertainties specific to the oil and gas industry which we cannot control. The oil and gas industry, by its nature, involves a high degree of risk. The value of these investments may be impacted by changes in the prices of oil, gas and natural gas liquids, which are affected by local, regional and global events or conditions that affect supply and demand and which have a history of significant price volatility. These investments are also exposed to changes in regulations affecting the industry, which could increase our cost of compliance, increase taxes or reduce or delay business opportunities. In addition, there are numerous uncertainties inherent in the estimation of future oil and gas production and future income streams associated with production. As a result, actual results could materially differ from those we currently anticipate and our ability to profitably grow these investments could be adversely affected.

Declines in the U.S. housing market may reduce revenues of Idaho Timber. Idaho Timber generates significant revenues when the U.S. housing market is strong. If the U.S. housing market were to decline, Idaho Timber's revenues and profitability would be adversely impacted.

We may not be able to insure certain risks economically. We cannot be certain that we will be able to insure all risks that we desire to insure economically or that all of our insurers or reinsurers will be financially viable if we make a claim. If an uninsured loss or a loss in excess of insured limits should occur, or if we are required to pay a deductible for an insured loss, results of operations could be adversely affected.

When Berkadia originates loans for Fannie Mae, it is normally required to share in the losses on such loans, which could be in excess of reserved amounts. Berkadia carries a reserve on its balance sheet for contingent losses on loans originated for Fannie Mae that have loss sharing requirements. If actual losses exceed amounts reserved, Berkadia’s profitability and cash flows will be reduced.

The loss of or changes in Berkadia’s relationships with U.S. Government-Sponsored Enterprises and federal agencies would have an adverse effect on Berkadia’s business. Berkadia’s failure to comply with U.S. Government-Sponsored Enterprise or federal agency requirements may result in its termination as an approved seller/servicer, mortgagee or issuer. The loss of any such status could have a significant adverse impact on Berkadia’s results of operations, could result in a loss of similar approvals from other U.S. Government-Sponsored Enterprises or federal agencies and could have other adverse consequences to the business. Fannie Mae and Freddie Mac retain broad discretion to terminate Berkadia as a seller/servicer without cause upon notice.

Changes in existing government-sponsored and federal mortgage programs could negatively affect Berkadia’s business.  Berkadia’s ability to generate income through mortgage sales to institutional investors depends in part on programs sponsored by Fannie Mae, Freddie Mac and the FHA, which purchase such loans from Berkadia and/or facilitate the issuance of mortgage-backed securities in the secondary market. Any discontinuation of, or significant reduction or change in, the operation of those programs would have an adverse effect on Berkadia’s loan origination and servicing business and results of operations.

Berkadia’s fee-for-service businesses may be terminated on short notice. Some of Berkadia's fee-for-service customers are permitted to terminate Berkadia on short notice, usually 30 days. If Berkadia loses fee-for-service customers, it would negatively impact Berkadia’s results of operations and cash flows.

Certain loan programs expose Berkadia to credit and interest rate risk that it is not subject to with its U.S. Government-Sponsored Enterprise and federal agency lending programs. Unlike its U.S. Government-Sponsored Enterprise and federal agency lending programs, Berkadia makes certain floating rate bridge loans which are held on Berkadia's balance sheet and not intended for sale. If for any reason a borrower is unable to pay off or refinance a bridge loan, Berkadia may be forced to foreclose on defaulted loans and suffer a loss, or to sell loans to a third party at a discount, either of which would reduce Berkadia’s profitability and cash flows. As of December 31, 2017, the aggregate amount of bridge loans on Berkadia's balance sheet was $672.0 million.

If Berkadia suffered significant losses and was unable torepay its commercial paper borrowings, we would be exposed to loss pursuant to a reimbursement obligation to Berkshire Hathaway. Berkadia obtains funds generated by commercial paper sales

19

of an affiliate of Berkadia. All of the proceeds from the commercial paper sales are used by Berkadia to fund new mortgage loans, servicer advances, investments and other working capital requirements. Repayment of the commercial paper is supported by a $1.5 billion surety policy issued by a Berkshire Hathaway insurance subsidiary and a Berkshire Hathaway corporate guaranty, and we have agreed to reimburse Berkshire Hathaway for one-half of any losses incurred thereunder. If Berkadia suffers significant losses and is unable to repay its commercial paper borrowings, we would suffer losses to the extent of our reimbursement obligation to Berkshire Hathaway. As of December 31, 2017, the aggregate amount of commercial paper outstanding was $1.47 billion.

Garcadia’s business is dependent, in part, upon revenue from new and used car sales at its dealerships, and declines in revenues due to industry or other factors could result in reduced profitability, reduced cash flows and/or impairment charges. Garcadia has recorded impairment charges in the past, principally for goodwill and other intangible assets, and if the automobile industry experiences a downturn in the future, additional impairment charges are likely, reducing our profitability.

From time to time we may invest in illiquid securities that are subject to standstill agreements or are otherwise restricted. From time to time we may invest in securities that are subject to restrictions which prohibit us from selling the subject securities for a period of time. Such agreements may limit our ability to generate liquidity quickly through the disposition of the underlying investment while the agreement is effective.

We could experience significant increases in operating costs and reduced profitability due to competition for skilled management and staff employees in our operating businesses. We compete with many other entities for skilled management and staff employees, including entities that operate in different market sectors than us. Costs to recruit and retain adequate personnel could adversely affect results of operations.

Extreme weather, loss of electrical power or other forces beyond our control could negatively impact our business. Natural disasters, fire, terrorism, pandemic or extreme weather, including droughts, floods, excessive cold or heat, hurricanes or other storms, could interfere with our operating businesses due to power outages, fuel shortages, water shortages, damage to facilities or disruption of transportation channels, among other things. Any of these factors, as well as disruptions to information systems, could have an adverse effect on financial results.

We rely on the security of our information technology systems and those of our third party providers to protect our proprietary information and information of our customers. Some of our businesses involve the storage and transmission of customers’ personal information, consumer preferences and credit card information. While we believe that we have implemented protective measures to effectively secure information and prevent security breaches, and we continue to assess and improve these measures, our information technology systems have been and may continue to be vulnerable to unauthorized access, computer hacking, computer viruses or other unauthorized attempts by third parties to access the proprietary information of our customers. Information technology breaches and failures could disrupt our ability to function in the normal course of business resulting in lost revenue, the disclosure or modification of sensitive or confidential information and the incurrence of remediation and notification costs, resulting in legal and financial exposure. Moreover, loss of confidential customer identification information could harm our reputation and subject us to liability under laws that protect confidential personal data, resulting in increased costs or loss of revenues.

Legal liability may harm our business. Many aspects of our businesses involve substantial risks of liability, and in the normal course of business, we have been named as a defendant or codefendant in lawsuits involving primarily claims for damages. The risks associated with potential legal liabilities often may be difficult to assess or quantify and their existence and magnitude often remain unknown for substantial periods of time. The expansion of our businesses, including expansions into new products or markets, impose greater risks of liability. In addition, unauthorized or illegal acts of our employees could result in substantial liability. Substantial legal liability could have a material adverse financial effect or cause us significant reputational harm, which in turn could seriously harm our businesses and our prospects. Although our current assessment is that, other than as disclosed in this report, there is no pending litigation that could have a significant adverse impact, if our assessment proves to be in error, then the outcome of litigation could have a significant impact on our financial statements.

Recent U.S. tax legislation may have a material adverse effect on our financial condition, results of operations and cash flows. Recently enacted U.S. tax legislation has made significant changes to the U.S. Internal Revenue Code, including the taxation of U.S. corporations by, among other things, limiting interest deductions, limiting deductibility of certain executive compensation, reducing the U.S. corporate income tax rate, disallowing certain deductions that had previously been allowed, altering the expensing of capital expenditures, adopting elements of a territorial tax system, assessing a repatriation tax or "transition tax" on undistributed earnings and profits of U.S. owned foreign corporations, and introducing certain anti-base erosion provisions. The legislation is highly complex and unclear in certain respects and will require interpretations and implementing regulations by the Internal Revenue Service and state tax authorities. Additionally, the legislation could be subject to potential amendments and technical corrections, any of which could lessen or increase certain adverse impacts of the legislation. Thus, the impact of certain aspects

20

of the legislation on us is currently unclear and could have an adverse impact on our financial condition, results of operations and cash flows.

We may not be able to generate sufficient taxable income to fully realize our deferred tax asset. At December 31, 2017, we have recognized net deferred tax assets of $743.8 million.  If we are unable to generate sufficient taxable income, we will not be able to fully realize the recorded amount of the net deferred tax asset. If we are unable to generate sufficient taxable income prior to the expiration of our federal income tax net operating loss carryforwards (“NOLs”), all or a portion of the NOLs would expire unused. Our projections of future taxable income required to fully realize the recorded amount of the net deferred tax asset reflect numerous assumptions about our operating businesses and investments, and are subject to change as conditions change specific to our business units, investments or general economic conditions. Changes that are adverse to us could result in the need to increase the deferred tax asset valuation allowance resulting in a charge to results of operations and a decrease to total stockholders’ equity.

If our tax filing positions were to be challenged by federal, state and local or foreign tax jurisdictions, we may not be wholly successful in defending our tax filing positions. We record reserves for unrecognized tax benefits based on our assessment of the probability of successfully sustaining tax filing positions. Management exercises significant judgment when assessing the probability of successfully sustaining tax filing positions, and in determining whether a contingent tax liability should be recorded and, if so, estimating the amount. If our tax filing positions are successfully challenged, payments could be required that are in excess of reserved amounts or we may be required to reduce the carrying amount of our net deferred tax asset, either of which result could be significant to our financial condition or results of operations.

We have indicated our intention to pay quarterly dividends at the annual rate of $0.40 per common share. The payment of dividends in the future is subject to the discretion of the Board of Directors and will depend upon general business conditions, legal and contractual restrictions on the payment of dividends and other factors that the Board of Directors may deem to be relevant.

Our common shares are subject to transfer restrictions. We and certain of our subsidiaries have significant NOLs and other tax attributes, the amount and availability of which are subject to certain qualifications, limitations and uncertainties.  In order to reduce the possibility that certain changes in ownership could result in limitations on the use of the tax attributes, our certificate of incorporation contains provisions that generally restrict the ability of a person or entity from acquiring ownership (including through attribution under the tax law) of 5% or more of our common shares and the ability of persons or entities now owning 5% or more of our common shares from acquiring additional common shares.  The restriction will remain until the earliest of (a) December 31, 2024, (b) the repeal of Section 382 of the Internal Revenue Code (or any comparable successor provision) and (c) the beginning of a taxable year to which these tax benefits may no longer be carried forward. The restriction may be waived by our Board of Directors on a case by case basis. Shareholders are advised to carefully monitor their ownership of our common shares and consult their own legal advisors and/or us to determine whether their ownership of our common shares approaches the proscribed level.

As of February 15, 2018, there were approximately1,544 record holders of the common shares.

We paid quarterly cash dividends of $0.10 per share for the each of the last two quarters of 2017 and $0.0625 per share for each of the first two quarters of 2017 and each quarter of 2016 and 2015. We have indicated our intention to pay quarterly dividends currently at the annual rate of $0.40 per common share. The payment of dividends in the future is subject to the discretion of the Board of Directors and will depend upon general business conditions, legal and contractual restrictions on the payment of dividends and other factors that the Board of Directors may deem to be relevant.

Certain of our subsidiaries have significant NOLs and other tax attributes, the amount and availability of which are subject to certain qualifications, limitations and uncertainties. In order to reduce the possibility that certain changes in ownership could result in limitations on the use of our tax attributes, our certificate of incorporation contains provisions which generally restrict the ability of a person or entity from acquiring ownership (including through attribution under the tax law) of 5% or more of the common shares and the ability of persons or entities now owning 5% or more of the common shares from acquiring additional common shares.  The restrictions will remain in effect until the earliest of (a) December 31, 2024, (b) the repeal of Section 382 of the Internal Revenue Code (or any comparable successor provision) or (c) the beginning of a taxable year to which these tax benefits may no longer be carried forward.

In November 2012, our Board of Directors authorized a share repurchase program pursuant to which we may, from time to time, purchase up to an aggregate of 25,000,000 of our common shares, inclusive of prior authorizations. During 2017, we repurchased a total of 3,661,588 shares in the open market pursuant to this program. Separately, during the year ended December 31, 2017, we repurchased an aggregate of 362,138 shares in connection with our share compensation plans which allow participants to use shares to satisfy certain tax liabilities arising from the vesting of restricted shares and the distribution of restricted share units. The total number of shares purchased does not include unvested shares forfeited back to us pursuant to the terms of our share compensation plans.

There were no unregistered sales of equity securities during the period covered by this report.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The purpose of this section is to discuss and analyze our consolidated financial condition, liquidity and capital resources and results of operations. This analysis should be read in conjunction with the consolidated financial statements and related footnote disclosures contained in this report and the following “Cautionary Statement for Forward-Looking Information.”

Cautionary Statement for Forward-Looking Information

Statements included in this report may contain forward-looking statements. Such statements may relate, but are not limited, to projections of revenues, income or loss, development expenditures, plans for growth and future operations, competition and regulation, as well as assumptions relating to the foregoing. Such forward-looking statements are made pursuant to the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995.

Forward-looking statements are inherently subject to risks and uncertainties, many of which cannot be predicted or quantified. When used in this report, the words “will,” “could,” “estimates,” “expects,” “anticipates,” “believes,” “plans,” “intends” and variations of such words and similar expressions are intended to identify forward-looking statements that involve risks and uncertainties.  Future events and actual results could differ materially from those set forth in, contemplated by or underlying the forward-looking statements.

Factors that could cause actual results to differ materially from any results projected, forecasted, estimated or budgeted or may materially and adversely affect our actual results include, but are not limited to, those set forth in Item 1A. Risk Factors and elsewhere in this report and in our other public filings with the SEC.

Undue reliance should not be placed on these forward-looking statements, which are applicable only as of the date hereof. Except as may be required by law, we undertake no obligation to revise or update these forward-looking statements to reflect events or circumstances that arise after the date of this report or to reflect the occurrence of unanticipated events.

Results of Operations

We focus on long-term value creation and invest in a broad variety of businesses. The mix of our business and investments change from time to time. Our investments may be reflected in our consolidated results as consolidated subsidiaries, equity investments, securities or in other ways, depending on the structure of our specific holdings. Further, as our investments span a number of industries, each may be impacted by different factors. For these reasons, our pre-tax income is not predictable or necessarily comparable from period to period.

Income from continuing operations before income taxes was $1,013.8 million for the year ended December 31, 2017. This compares to $316.4 million for the year ended December 31, 2016. The increase of $697.4 million reflects improved performance across many of Leucadia’s businesses. Jefferies pre-tax income increased $484.3 million due to record investment banking and equities revenues. National Beef’s pre-tax income grew by $78.3 million, as increased cattle availability and strong demand for beef continued to support strong margins.  Other Financial Services Businesses and Investments pre-tax income increased by $39.2 million, as Berkadia continued its strong performance and Leucadia Asset Management made a positive contribution, offset by an impairment charge of $130.2 million early in the year to revalue our equity method investment in FXCM.  Other Merchant Banking Businesses and Investments pre-tax income was higher than the previous year by $193.0 million, primarily related to the gain on the sale of Conwed.  Pre-tax income of our Corporate and Other segment was lower by $97.3 million due primarily to an increase in the fair value of a trading asset during 2016.

Jefferies

Jefferies was acquired on March 1, 2013 and is reflected in our consolidated financial statements utilizing a one month lag; Jefferies fiscal year ends on November 30^th and its fiscal quarters end one month prior to our reporting periods. A summary of results of operations for Jefferies included in the years ended December 31, 2017, 2016 and 2015 is as follows (in thousands):

Jefferies comprises many business units, with many interactions and much integration among them. Business activities include the sales, trading, origination and advisory effort for various equity, fixed income, commodities, foreign exchange and advisory services.  Jefferies business, by its nature, does not produce predictable or necessarily recurring revenues or earnings. Jefferies results in any given period can be materially affected by conditions in global financial markets, economic conditions generally, and its own activities and positions.

28

On April 9, 2015, Jefferies entered into an agreement to transfer certain of the client activities of its Jefferies Bache business to Société Générale S.A. During the second quarter of 2016, Jefferies completed the exit of the Futures business. Net revenues globally from this business activity, which are included within Jefferies fixed income results, and expenses directly related to the Bache business, which are included within non-interest expenses, were $80.2 million and $214.8 million, respectively, in 2015. There were no meaningful revenues or expenses from the Bache business for 2016. Total expenses for 2015 include costs of $73.1 million, on a pre-tax basis, related to the exit of the Bache business. These costs consist primarily of severance, retention and benefit payments for employees, incremental amortization of outstanding restricted stock and cash awards, contract termination costs and incremental amortization expense of capitalized software expected to no longer be used subsequent to the wind-down of the business. For further information, refer to Note 30 in our consolidated financial statements.

The discussion below is presented on a detailed product and expense basis. Net revenues presented for equity and fixed income businesses include allocations of interest income and interest expense as Jefferies assesses the profitability of these businesses inclusive of the net interest revenue or expense associated with the respective sales and trading activities, which is a function of the mix of each business’s associated assets and liabilities and the related funding costs.

The following provides a summary of net revenues by source included in the years ended December 31, 2017, 2016 and 2015 (in thousands):

Net Revenues

Net revenues for 2017 were an annual record and reflect record investment banking revenues and record equities net revenues, partially offset by lower fixed income net revenues. The record investment banking revenues reflect record debt capital markets revenues, record advisory revenues and significantly higher equity capital markets revenues, as a result of higher transaction volumes and values throughout 2017, driven in part by Jefferies effort to continue to expand its investment banking team through promotions and new hires. The increase in equities revenues was primarily attributable to a net gain of $117.3 million recognized during 2017 from Jefferies investment in two equity positions, including KCG Holdings, Inc. ("KCG"), compared with a net loss of $17.9 million during 2016 from these two equity positions. KCG was sold for $20.00 per share in cash on July 20, 2017. The increase in equities net revenues was also due to net revenues of $90.8 million from Jefferies share of its Jefferies Finance, LLC ("Jefferies Finance") joint venture during 2017, compared with a net loss of $9.3 million during 2016. The decrease in fixed income net revenues is primarily due to lower volumes and volatility, which negatively impacted Jefferies client flow oriented fixed income businesses in the last nine months of 2017. Net revenues for 2017 included investment losses from managed funds of $4.0 million, compared with investment income from managed funds of $4.7 million during 2016.

Net revenues for 2016 were impacted by an extremely volatile bear market environment during the first three months of the year, with meaningful improvement over the rest of the year. Net revenues for the first quarter of 2016 declined $292.7 million or 49.5% in comparison to the first quarter of 2015. The decrease in total net revenues for 2016 primarily reflects lower net revenues in investment banking and equities, partially offset by increased revenues in fixed income. Net revenues for 2016 included investment income from managed funds of $4.7 million, compared with investment losses from managed funds of $23.8 million in 2015, primarily due to lower valuations in the energy and shipping sectors in 2015.

Net revenues for 2015 reflect the impact of challenging market conditions throughout the year on Jefferies fixed income business, partially offset by increased revenues in Jefferies equities business. Almost all of Jefferies fixed income credit businesses were

29

impacted by lower levels of liquidity due to the expectations of interest rate increases by the Federal Reserve and deterioration in the global energy and distressed markets.

Equities Net Revenues

Equities net revenues include equity commissions, equity security principal trading and investments (including Jefferies investments in KCG and from time to time, other blocks of equity securities) and net interest revenue generated by its equities sales and trading, prime services and wealth management business relating to cash equities, electronic trading, equity derivatives, convertible securities, prime brokerage, securities finance and alternative investment strategies. KCG was sold on July 20, 2017. Jefferies recognized a $93.4 million gain from its holdings of KCG in 2017 and an aggregate gain of $347.7 million over the five year life of this investment. Equities net revenues also include Jefferies share of the net earnings of its joint venture investments in Jefferies Finance and Jefferies LoanCore, LLC ("Jefferies LoanCore"), which are accounted for under the equity method. On October 31, 2017, Jefferies sold all of its membership interests in Jefferies LoanCore for approximately $173.1 million, the estimated book value at October 31, 2017. In addition, Jefferies may be entitled to additional cash consideration over the next five years in the event Jefferies LoanCore’s yearly return on equity exceeds certain thresholds.

Equities net revenues were $804.6 million for 2017 compared with $553.2 million in 2016. Equities revenue for 2017 include a net gain of $117.3 million from Jefferies investment in two equity positions, including KCG, compared with a net loss of $17.9 million in 2016 from these two equity positions.

Equities net revenues related to the core equities businesses during 2017 increased with higher revenues in Jefferies electronic trading, prime services, and Asia Pacific cash equities businesses primarily due to increased customer activity and increased trading volumes. The increase was partially offset by lower revenues in its equity options and Europe cash equities businesses, primarily due to reduced market making activities and lower equity volatility. In addition, 2016 included certain strategic investment gains from exposures to energy, volatility, financial and currency markets.

Equities commission revenues declined in Jefferies equity derivative and U.S. cash equities businesses due to reduced trading volumes and lower levels of volatility, partially offset by higher revenues in its electronic trading and Asia Pacific cash equities businesses due to increased trading volumes.

Equities net revenues during 2017 include net revenues of $90.8 million from Jefferies share of Jefferies Finance, primarily due to an increase in loan syndication activity, compared with a net loss of $9.3 million in the prior year, primarily due to the mark down of certain loans held for sale. Net revenues from Jefferies share of Jefferies LoanCore increased slightly during 2017 as compared to 2016 due to an increase in loan closings and syndications. On October 31, 2017, Jefferies sold all of its membership interests in Jefferies LoanCore for approximately $173.1 million, the estimated book value at October 31, 2017.

Total equities net revenues were $553.2 million for 2016 compared with $757.8 million in 2015. Results for 2016 includes a net loss of $17.9 million from Jefferies investment in two equity positions, including KCG, as compared to gains of $49.1 million in 2015 from these two equity positions. In addition, equities net revenues for 2015 included significant gains on additional securities positions, which were not repeated during 2016. Equities commission revenues gained slightly with improved market share across various product and client segments. Commissions in Jefferies U.S. cash equities and equity derivatives businesses held firm, while global electronic trading commissions gained from increased volumes and client market share. In Jefferies global electronic trading business, Jefferies has market leading customized algorithms in over 40 countries. European equities commissions increased due to improved market share, while commissions in Jefferies Asia Pacific cash equities business declined because of a challenging market environment. Jefferies global cash businesses were among the highest market share gainers compared with Jefferies peers and, in the U.S. and U.K., Jefferies platform remains in the top 10.

Equities trading revenues were solid across most of Jefferies equities sales and trading businesses in 2016. Trading revenues from client market making improved in Jefferies U.S. and European cash equities businesses. Equity derivatives trading revenues declined due to a difficult volatility trading climate and convertibles trading revenues declined driven by weakness in the energy sector during 2016. In addition, certain strategic investments gained from exposures to energy, volatility, financial and currency markets.

Equities net revenues during 2016 included a net loss of $9.3 million from Jefferies share of Jefferies Finance, primarily due to the mark down of certain loans held for sale during the first part of 2016, compared with net revenues of $41.4 million in 2015. Net revenues from Jefferies share of Jefferies LoanCore also decreased during 2016 as compared to 2015 due to a decrease in loan closings and syndications.

Fixed Income Net Revenues

Fixed income net revenues include commissions, principal transactions and net interest revenue generated by Jefferies fixed income sales and trading businesses from investment grade corporate bonds, mortgage- and asset-backed securities, government and agency securities, high yield and distressed securities, bank loans, municipal bonds, emerging markets debt, foreign exchange and interest rate derivatives,

Fixed income net revenues for 2017 decreased $21.2 million as compared to 2016, primarily due to a more challenging trading environment across most products, including most credit and rates businesses. In 2017, volatility was dampened as quantitative easing continued across most markets Jefferies transacts in. This was partially offset by better risk management, addition of staff in certain businesses, and refreshed strategies in some businesses.

Net revenues in Jefferies leveraged credit business in 2017 were higher due to increased trading activities in high yield and distressed products as a result of additions to staff and repositioned risk. This was compared to relatively significant mark-to-market losses recognized in the early part of 2016. Higher revenues in its European credit and international securitized markets group businesses were due to repositioned strategies taking advantage of trading opportunities in certain industry sectors. This is compared to volatile oil prices and uncertainty as to bank liquidity in 2016, which negatively impacted revenues in this business in the prior year.

Jefferies municipal securities business performed extremely well for the greater part of the year, driven by increased client activity as new team members were added and market share expanded. Performance for the municipal securities business was partially dampened at the end of the 2017 fiscal year as the municipal bond market dislocated over concerns around the potential impacts of pending U.S. tax reform on both municipal bond issuers and investors.

Revenues in Jefferies corporates and emerging markets business declined in a maturing credit cycle as volatility and transaction spreads decreased from prior year levels, while demand for new issuances and higher yielding investments and higher levels of volatility were prevalent in 2016. Lower revenues in its global rates and U.S. securitized markets group business were due to lower levels of volatility resulting in lower transaction based revenues. In the U.S. securitized markets businesses this was partially offset by increased activity in origination businesses including collateralized loan obligations (“CLOs”).

Jefferies recorded higher revenues in 2016 as compared with 2015 due to improved trading conditions across most core businesses, partially offset by lower revenues in its international rates business due to lower trading volumes. 2015 included $80.2 million of net revenues globally from the Bache business activity. There were no meaningful revenues from the Bache business during 2016, as Jefferies completed the exit of the Bache business during the second quarter of 2016. Excluding revenues from the Bache business activity, revenues increased $451.2 million.

Revenues in Jefferies leveraged credit business were strong on increased trading volumes within high yield and distressed products, as a result of an improved credit environment, as well as strategic growth in the business, compared with mark-to-market write-downs in 2015. Results in Jefferies emerging markets business during 2016 were higher as compared to 2015 due to an upgraded sales and trading team and increased levels of volatility and improved market conditions. Revenues in 2016 from Jefferies corporates businesses increased as compared to 2015 due to increased client activity and higher demand for new issuances and higher yielding investments. Jefferies securitized markets businesses were positively impacted by increased demand for spread products compared with the negative impact of market volatility as credit spreads tightened for these asset classes and expectations of future rate increases in 2015. The municipal securities business performed well during 2016 as improved trading activity was driven by market technicals compared with net outflows in 2015. Volatility during 2016 due to fluctuating expectations as to future Federal Reserve interest rate increases contributed to increased revenues in Jefferies U.S. rates business as compared to the prior year.

Investment Banking Revenues

Jefferies provides a full range of capital markets and financial advisory services to its clients across most industry sectors in the Americas, Europe and Asia. Capital markets revenues include underwriting and placement revenues related to corporate debt, municipal bonds, mortgage- and asset-backed securities and equity and equity-linked securities. Advisory revenues consist primarily of advisory and transaction fees generated in connection with merger, acquisition and restructuring transactions.

Total investment banking revenues were $1,764.3 million for 2017, 47.8% higher than 2016. This increase was due to strong performance across Jefferies debt capital markets, equity capital markets and advisory businesses, supported by a strong overall capital raising and merger and acquisition environment. In 2016, new issue equity and leveraged finance capital markets were virtually closed throughout January and February and remained slow throughout 2016. Capital markets revenues for 2017 increased 84.2% from 2016. Advisory revenues for 2017 increased 17.7% compared to the prior year.

31

From equity and debt capital raising activities, Jefferies generated $345.0 million and $649.2 million in revenues, respectively, for the year ended December 31, 2017. During 2017, Jefferies completed 1,121 public and private debt financings that raised $292.1 billion in aggregate and Jefferies completed 173 public and private equity and convertible offerings that raised $59.7 billion (164 of which Jefferies acted as sole or joint bookrunner). Financial advisory revenues totaled $770.1 million, including revenues from 171 merger and acquisition transactions and 10 restructuring and recapitalization transactions with an aggregate transaction value of $180.6 billion.

Total investment banking revenues were $1,194.0 million for 2016, 17.0% lower than 2015. Lower investment banking results were attributable to lower new issue equity and leveraged finance capital markets revenues. This was primarily as a result of the capital markets slowdown, which began in the second half of 2015 and continued for much of 2016. From equity and debt capital raising activities, Jefferies generated $235.2 million and $304.6 million in revenues, respectively, for 2016, a decrease of 42.4% and 23.5%, respectively, from 2015.

Jefferies reduced capital markets activity for 2016 was partially offset by increased advisory revenues. Specifically, Jefferies advisory revenues for 2016 increased 3.5% compared to 2015, primarily through an increase in the number of merger, acquisition and restructuring transactions, including closing a record number of merger and acquisition transactions in excess of $1 billion. Jefferies investment banking results benefited both from a record fourth quarter of advisory fees in 2016, with Jefferies merger, acquisition and restructuring and recapitalization businesses showing continued momentum, and from improvement in capital markets activity, which began in the late summer of 2016, leading to an increase in new issue transaction volume.

During 2016, Jefferies completed 892 public and private debt financings that raised $188.6 billion in aggregate and Jefferies completed 129 public and private equity and convertible offerings that raised $24.4 billion (125 of which Jefferies acted as sole or joint bookrunner). Financial advisory revenues totaled $654.2 million, including revenues from 161 merger and acquisition transactions and 18 restructuring and recapitalization transactions with an aggregate transaction value of $135.2 billion.

During 2015, Jefferies generated $1,438.8 million in investment banking revenues. From equity and debt capital raising activities, Jefferies generated $408.5 million and $398.0 million in revenues, respectively, in 2015. Advisory revenues of $632.4 million for 2015 were primarily due to higher transaction volume. During 2015, Jefferies completed 1,003 public and private debt financings that raised $199.8 billion in aggregate and Jefferies completed 203 public and private equity and convertible offerings that raised $56.6 billion (183 of which Jefferies acted as sole or joint bookrunner). Financial advisory revenues totaled $632.4 million, including revenues from 158 merger and acquisition transactions and 13 restructuring and recapitalization transactions with an aggregate transaction value of $141.1 billion.

Compensation and Benefits

Compensation and benefits expense consists of salaries, benefits, cash bonuses, commissions, annual cash compensation awards, and the amortization of certain non-annual share-based and cash compensation awards to employees. Cash and historical share-based awards and a portion of cash awards granted to employees as part of year end compensation generally contain provisions such that employees who terminate their employment or are terminated without cause may continue to vest in their awards, so long as those awards are not forfeited as a result of other forfeiture provisions (primarily non-compete clauses) of those awards.  Accordingly, the compensation expense for a portion of awards granted at year end as part of annual compensation is recorded in the year of the award.

Included in Compensation and benefits expense is share-based amortization expense for senior executive awards granted in September 2012, February 2016 and January 2017, non-annual share-based and cash-based awards to other employees and certain year end awards that contain future service requirements for vesting, all of which are being amortized over their respective future service periods. In addition, the senior executive awards contain market and performance conditions. Compensation expense related to the amortization of share-based and cash-based awards amounted to $278.2 million, $287.3 million and $307.7 million for 2017, 2016 and 2015, respectively.Compensation and benefits as a percentage of Net revenues was 57.1%, 64.8% and 59.3% for 2017, 2016 and 2015, respectively.

Compensation and benefits expense directly related to Jefferies Bache business was $87.7 million for 2015 and was not meaningful for 2016. Included within Compensation and benefits expense for the Bache business for 2015 are severance, retention and related benefits costs of $38.2 million, incurred as part of decisions surrounding the exit of this business.

32

Non-Compensation Expenses

Non-compensation expenses include floor brokerage and clearing fees, technology and communications expense, occupancy and equipment rental expense, business development, professional services, bad debt provision, impairment charges, depreciation and amortization expense and other costs. All of these expenses, other than floor brokerage and clearing fees and depreciation and amortization expense, are included in Selling, general and other expenses in the Consolidated Statements of Operations.

In 2017, non-compensation expenses increased 5.0% compared to 2016. The increase in non-compensation expenses during 2017 was consistent with the increased activity associated with higher net revenues, as well as increased spending on technology. At the same time, non-compensation expenses as a percentage of Net revenues declined from 33.4% to 26.5% again demonstrating strategically the operating leverage inherent in Jefferies business. The increase in non-compensation expenses was primarily due to an increase in Floor brokerage and clearing expenses due to the mix of costs across certain equities and fixed income businesses, technology and communications expenses due to costs associated with the development of the various trading systems and projects associated with corporate support and core business infrastructures, and an increase in certain other expenses.

In 2016, non-compensation expenses decreased 9.1% compared to 2015. The decrease in 2016 was due to the exiting of the Bache business, which in 2015 generated $127.2 million of non-compensation expenses, including accelerated amortization expense of $19.7 million related to capitalized software, $11.2 million in contract termination costs and professional services costs of approximately $2.5 million in connection with Jefferies actions in exiting the Bache business. There were no meaningful non-compensation expenses related to the Bache business in 2016. This reduction in 2016 was partially offset by higher technology and communications expenses, excluding the Bache business, and higher professional services expenses, excluding the Bache business. Technology and communications expenses, excluding the Bache business, increased due to higher costs associated with the development of the various trading systems and projects associated with corporate support infrastructure. In both years, Jefferies continued to incur legal and consulting fees as part of implementing various regulatory requirements. During 2015, Jefferies also released $4.4 million in reserves related to the resolution of bankruptcy claims against Lehman Brothers Holdings, Inc.

Income (loss) before income taxes	$	407,312	$	329,022	$	(123,915	)

National Beef’s profitability is dependent, in large part, on the spread between its cost for live cattle, the primary raw material for its business, and the value received from selling boxed beef and other products coupled with its overall volume. National Beef operates in a large and liquid commodity market and it does not have much influence over the price it pays for cattle or the selling price it receives for the products it produces. National Beef’s profitability typically fluctuates seasonally with relatively higher margins in the spring and summer months and during times of ample cattle availability. National Beef's fiscal year consists of 52 or 53 weeks, ending on the last Saturday in December. National Beef's fiscal years 2017 and 2015 consisted of 52 weeks each and its fiscal 2016 consisted of 53 weeks.

Revenues in 2017 increased 5% in comparison to 2016, primarily due to an increase in the number of cattle processed. Cost of sales increased by 4% in 2017 as compared to 2016. The increase is also due to an increase in the number of cattle processed. The combined effects of increased margin per head and an increase in volume led to higher profitability in 2017 as compared to 2016.

33

Revenues in 2016 decreased about 5% in comparison to 2015, due to lower average selling prices for beef and beef by-products, partially offset by an increase in the number of cattle processed. Additionally, during 2015, decreases to revenues of $52.9 million were recorded as a result of National Beef's use of derivatives in its hedging activity. For 2016, cost of sales declined 11% as compared to 2015, due to a decrease in the price of fed cattle, partially offset by an increase in volume. For 2016, the combined effects of increased margin per head and an increase in volume led to higher profitability as compared to 2015.

Lower average debt balances in 2017 and 2016 led to a 49% decline in interest expense in 2017 as compared to 2016 and a 22% decline in interest expense in 2016 as compared to 2015.

Net revenues of corporate and other primarily include realized and unrealized securities gains and interest income for investments held at the holding company. Net revenues for 2017 and 2016, respectively, include a $6.1 million and $65.6 million increase in a trading asset which is held at fair value. Net revenues for 2017 also include a $19.7 million realized security gain from an investment in a non-public security. Net revenues for 2015 include a realized security gain related to a recovery of $35.0 million of an investment in a non-public security that was sold and had been written off in prior years.

For the years ended December 31, 2017, 2016 and 2015, corporate compensation and benefits includes incentive bonus expense of $10.1 million, $7.6 million and $17.4 million, respectively. Share-based compensation expense was $20.9 million, $9.7 million and $14.6 million in 2017, 2016 and 2015, respectively. Compensation and benefits also increased in 2017 compared to 2016 as a result of the growth of our other investments.

Pursuant to the agreement to sell one of our former subsidiaries, WilTel Communications Group, LLC, the responsibility for WilTel’s defined benefit pension plan was retained by us. WilTel pension expense in 2015 includes a non-cash pension settlement charge of $40.7 million related to a voluntary lump sum offer to participants of the legacy plan. See Note 19 to our consolidated financial statements for further information.

Selling, general and other expenses for 2017 reflects the write-down of a note receivable of $20.0 million related to the prior sale of a subsidiary. Selling, general and other expenses also increased in 2017 compared to 2016 as a result of the growth of our other investments. Selling, general and other expenses for 2015 reflects the recovery of $20.1 million in insurance payments in respect of previously expensed legal fees.

Our other financial services businesses and investments include the consolidated results of Leucadia Asset Management fund managers, the returns on our investments in these funds, the consolidated results of Foursight Capital and Chrome Capital (vehicle finance), our share of the income of Berkadia, the results of our investment in FXCM and our share of the income of HomeFed.

Excluding the FXCM revenues discussed below, the net revenues in other financial services businesses and investments reflect revenues of $168.7 million, $8.6 million and $32.7 million for the years ended December 31, 2017, 2016 and 2015, respectively. The year-over-year increase in 2017 revenues as compared to 2016 primarily reflects greater returns on investments related to the Leucadia Asset Management businesses and at our 54 Madison real estate fund. The year-over-year decrease in 2016 compared to 2015 primarily reflects losses on investments recorded at market value related to the Leucadia Asset Management businesses partially offset by growth in our vehicle finance businesses and at our 54 Madison real estate fund.

All expense categories were impacted by the growth of our Leucadia Asset Management businesses and vehicle finance businesses in 2017 and 2016 as compared to the prior years. Selling, general and other expenses for 2015 also include $21.0 million of investment banking and advisory fees paid to Jefferies in connection with our entering into the agreement with FXCM, and which Jefferies recognized in net revenues.  These intercompany fees have been eliminated in our consolidated results. Income (losses) from continuing operations before income taxes related to our Leucadia Asset Management businesses totaled $27.0 million, $(109.9) million and $(32.6) million for 2017, 2016 and 2015, respectively. Income (losses) from continuing operations before income taxes at our Leucadia Asset Management businesses primarily reflect the continued build out of the businesses, as well as returns on investments recorded at market value.

For the years ended December 31, 2017, 2016 and 2015, income related to associated companies attributable to Berkadia was $93.8 million, $94.2 million and $78.1 million, respectively. Berkadia's results were impacted by reversals of mortgage service rights impairments of $35.9 million in 2016, and investment gains of $15.4 million in 2015, of which we then recorded our applicable share. As our share of profits from Berkadia are primarily taxed at the Leucadia level, the income discussed above is pre-tax. Income related to associated companies attributable to HomeFed was $7.7 million, $23.9 million and $3.6 million for the years ended December 31, 2017, 2016 and 2015, respectively. The increase in 2016 primarily reflects a reversal of HomeFed's deferred tax valuation allowance in 2016 as HomeFed concluded that it was more likely than not that they would have future taxable income sufficient to realize their net deferred tax asset.

As more fully discussed in Note 4 to our consolidated financial statements, on September 1, 2016, we amended the terms of our loan and associated rights.Among other changes, the amendments gave Leucadia a 50% voting interest in FXCM and we gained the ability to significantly influence FXCM through our seats on the board. As a result of the amendment, we have accounted for our equity interest in FXCM under the equity method of accounting since September 1, 2016. Net revenues include gains (losses) of $23.2 million during 2017 from our FXCM term loan and $(54.6) million and $491.3 million, respectively, during 2016 and 2015 from our FXCM term loan and related rights. This includes the component related to interest income, which is recorded within Principal transactions revenues. We also recorded income (losses), before impairment charges, related to our equity method investment in FXCM of $(47.4) million and $1.9 million during 2017 and 2016, respectively.

35

During February 2017, Global Brokerage Holdings and FXCM's U.S. subsidiary, FXCM U.S. settled complaints filed by the NFA and the CFTC against FXCM U.S. and certain of its principals relating to matters that occurred between 2010 and 2014. As part of the settlements, FXCM U.S. withdrew from business and sold FXCM U.S.'s customer accounts. FXCM also implemented a restructuring plan that included the termination of approximately 22% of its global workforce.

Based on the above February 2017 actions, we evaluated in the first quarter of 2017 whether our equity method investment was fully recoverable. We engaged an independent valuation firm to assist management in estimating the fair value of FXCM. Our estimate of fair value was based on a discounted cash flow and comparable public company analysis. The result of our analysis indicated that the estimated fair value of our equity interest in FXCM was lower than our carrying value by $130.2 million. We concluded based on the above regulatory actions, FXCM's restructuring plan, investor perception and declines in the trading price of Global Brokerage, Inc.'s ("Global Brokerage") common shares and convertible debt, that the decline in fair value of our equity interest was other than temporary. As such, we impaired our equity investment in FXCM in the first quarter of 2017 by $130.2 million.

Other Merchant Banking Businesses and Investments

Our other merchant banking operations include our ownership of HRG shares, which is accounted for at fair value and impacts our results through its mark-to-market adjustments reflected in net revenues, and the consolidated results of Vitesse and JETX (oil and gas production and development) and Conwed and Idaho Timber (manufacturing companies). It also includes our equity investments in Garcadia (automobile dealerships), Linkem (fixed wireless broadband services in Italy) and Golden Queen (a gold and silver mining project). 

Net revenues include principal transactions related to unrealized gains (losses) of $64.8 million, $93.2 million and $(28.0) million for the years ended December 31, 2017, 2016 and 2015, respectively, from the change in value of our investment in HRG. We classify HRG as a trading asset for which the fair value option was elected and we reflect mark-to-market adjustments through Principal transactions revenues.

For the years ended December 31, 2017, 2016 and 2015, net revenues for manufacturing were $504.5 million (including the gain on the sale of Conwed of $178.2 million, net of working capital adjustments), $415.8 million and $392.1 million, respectively. 

Net revenues for the years ended December 31, 2017, 2016 and 2015 for our oil and gas production and development businesses were $45.2 million, $53.5 million and $54.1 million, respectively. As discussed further in Note 4 to our consolidated financial statements, Vitesse uses swaps and call and put options in order to reduce exposure to future oil price fluctuations. Net unrealized gains (losses) of $1.8 million, $(11.8) million and $7.4 million were recorded related to these derivatives in 2017, 2016 and 2015, respectively. JETX revenues during 2017 and 2016 were impacted by $(20.1) million and $9.6 million, respectively, of unrealized gains (losses) on a trading asset which is held at fair value.

36

The decrease in cost of sales for 2017 as compared to 2016 is primarily due to the sale of Conwed in the first quarter of 2017.

For the years ended December 31, 2017, 2016 and 2015, Selling, general and other expenses for manufacturing were $2.8 million, $9.2 million and $8.6 million, respectively. Selling, general and other expenses for our oil and gas production and development businesses were $35.3 million, $109.1 million and $49.8 million in 2017, 2016 and 2015, respectively. Total selling, general and other expenses decreased $91.7 million in 2017 as compared to 2016, primarily reflecting lower costs for our oil and gas production and development businesses and the sale of Conwed in early 2017. Selling, general and other expenses for our oil and gas production and development businesses include impairment charges of $10.1 million, $63.8 million and $20.3 million recorded by JETX in 2017, 2016 and 2015, respectively. The 2017 impairment charge related to the write-off of the remaining Houston County acreage due to the decision made in 2017 to focus on JETX's other higher returning acreage. The 2016 impairment charge primarily related to decisions made by JETX in the third quarter to curtail development of both its southern acreage in the East Eagle Ford and its Houston County acreage. A $55.0 million impairment charge was then recorded for the difference between the carrying value of that acreage and the estimated net realizable value. The 2016 impairment also included the write-down of certain JETX leases that would not benefit its business going forward. The 2015 impairment charge related to the write-down of JETX oil field assets in Houston County to fair value.

Depreciation and amortization for the oil and gas production and development businesses were $29.9 million, $30.4 million and $25.1 million in 2017, 2016 and 2015, respectively. The significant increase in 2017 and 2016 is due to increased production and additional wells compared to 2015.

Income related to associated companies primarily relates to our investments in Garcadia and Linkem. For the years ended December 31, 2017, 2016 and 2015, income related to Garcadia was $48.2 million, $52.3 million and $53.2 million, respectively, and losses related to Linkem were $32.6 million, $22.9 million and $15.6 million, respectively.

Pre-tax income for 2017 includes $208.0 million from manufacturing, including the gain on the sale of Conwed of $178.2 million (including working capital adjustments), $7.9 million of income related to associated companies and $64.8 million related to our investment in HRG, offset partially by pre-tax losses from the oil and gas production and development businesses of $26.0 million. Pre-tax income for 2016 includes $93.2 million related to our investment in HRG, $39.8 million from manufacturing and $26.4 million of income related to associated companies, offset by pre-tax losses for the oil and gas production and development businesses of $90.8 million. Pre-tax losses for 2015 includes losses of $28.0 million related to our investment in HRG and pre-tax losses for the oil and gas production and development businesses of $31.9 million, partially offset by $31.1 million of income from manufacturing and $28.0 million of income related to associated companies.

Parent Company Interest

Parent company interest totaled $58.9 million, $58.9 million and $87.2 million for 2017, 2016 and 2015, respectively. The decline in interest expense in 2016 as compared to 2015 is primarily due to the repayment of our 8.125% Senior Notes in September 2015.

Income Taxes

On December 22, 2017, the Tax Cuts and Jobs Act (the "Tax Act") was enacted. The Tax Act is one of the most comprehensive changes in the U.S. corporate income tax since 1986 and certain provisions are complex in their application. The Tax Act revises the U.S. corporate income tax by, among other things, lowering the corporate income tax rate from 35% to 21%, adopting a territorial income tax system, and imposing a transition tax on unremitted earnings of foreign subsidiaries. In connection with our initial analysis, we have recorded a discrete tax expense of $450.5 million as a provisional estimate of the impact of the Tax Act during 2017. This provisional estimate primarily consists of a $415.0 million expense related to the revaluation of our deferred tax asset and a $35.5 million expense related to the deemed repatriation of foreign earnings.

For the year ended December 31, 2017, our provision for income taxes was $761.0 million, representing an effective tax rate of about 75%. Our 2017 provision was impacted by a non-cash $450.5 million charge related to the impact of tax reform. This charge increased our effective rate by 44%. Additionally, our 2017 provision was reduced by a $31.9 million benefit resulting from the repatriation of Jefferies earnings from certain of its foreign subsidiaries, along with their associated foreign tax credits. This benefit reduced our effective tax rate for 2017 by approximately 3%.

For the year ended December 31, 2016, our provision for income taxes was $122.1 million, representing an effective tax rate of about 39%. Our 2016 provision was increased by a $24.9 million charge related to previously issued stock awards, which increased our effective rate by 8%. The majority of the awards expired unexercised during the first quarter of 2016. The tax deductions associated with the remainder of the awards was less than the compensation cost recognized for financial reporting purposes.

37

For the year ended December 31, 2015, our provision for income taxes was $109.9 million, representing an effective tax rate of about 31%. Our 2015 provision was reduced by $10.7 million, lowering our effective rate by 3%, related to benefits recorded for certain state and local net operating loss carryforwards, which are more likely than not to be realized in the future.

Discontinued Operations

Our gain on disposal from discontinued operations, net of tax totaled $5.1 million in 2015. This gain primarily relates to additional consideration received related to the 2012 sale of our small Caribbean-based telecommunications provider and a reversal of a legal reserve.

Selected Balance Sheet Data

In addition to preparing our Consolidated Statements of Financial Condition in accordance with accounting principles generally accepted in the United States of America (“GAAP”), we also review the tangible capital associated with each of our businesses and investments, which is a non-GAAP presentation and may not be comparable to similar non-GAAP presentations used by other companies. We believe that this information is useful to investors as it allows them to view our businesses and investments through the eyes of management while facilitating a comparison across historical periods. We define tangible capital as Total Leucadia National Corporation shareholders' equity less Intangible assets, net and goodwill.

Liquidity and Capital Resources

Corporate Liquidity

We are a holding company whose assets principally consist of the stock or membership interests of our subsidiary businesses, cash and cash equivalents and other noncontrolling investments in debt and equity securities. We continuously evaluate the retention and disposition of our existing operations and investments and investigate possible acquisitions of new businesses in order to maximize shareholder value. Accordingly, further acquisitions, divestitures, investments and changes in capital structure are possible.

Our principal sources of funds are distributions from subsidiaries, proceeds from divestitures of existing businesses and investments, repayment of subsidiary advances, available cash resources, liquid investments, funds distributed from subsidiaries as tax sharing payments, public and private capital market transactions, and management and other fees.

During the year ended December 31, 2017, we received $553.0 million of distributions from our existing subsidiary businesses, including $337.7 million from National Beef. We also received $463.7 million from divestitures and repayments of advances, including $289.8 million from the sale of 100% of Conwed and $92.8 million of principal repayments from FXCM.

41

Our available cash resources and investments that are easily convertible into cash within a relatively short period of time total $1,325.4 million at December 31, 2017, and are primarily comprised of cash, short-term bonds and notes of the U.S. Government and its agencies, and other publicly traded debt and equity securities. These are classified on our balance sheet as cash and cash equivalents, trading assets, available for sale securities, receivables and investments in managed funds.

Our short-term recurring cash requirements, which are principally the payment of interest on our debt, dividends and corporate cash overhead expenses, totaled $247.6 million for the year ended December 31, 2017. Dividends paid during 2017 of $117.4 million include quarterly dividends of $0.0625 per share for each of the first two quarters and $0.10 per share for each of the last two quarters. The payment of dividends is subject to the discretion of the Board of Directors and depends upon general business conditions, legal and contractual restrictions on the payment of dividends and other factors that the Board of Directors may deem to be relevant. Our recurring cash requirements typically do not include significant amounts for tax payments, as we have federal income tax net operating loss carryforwards (“NOLs”) and other tax attributes which offset federal tax liabilities. During 2017, we used about $700 million of our NOLs to offset taxable income, and we have about $2.3 billion remaining NOLs as of December 31, 2017.

Our primary long-term cash requirement is to make principal payments on the parent company’s long-term debt ($1.0 billion principal outstanding as of December 31, 2017), of which $750.0 million is due in 2023 and $250.0 million in 2043.

We continue to use our available liquidity to make acquisitions of new businesses and other investments, additional contributions to existing businesses, and from time to time, repurchases of our outstanding common shares. The timing of these events is influenced by many factors and therefore cannot be predicted.

During 2017, we bought 797,897 additional common shares of HomeFed for $31.9 million in privately-negotiated transactions, and participated in a preferred equity financing for Linkem, of which Leucadia’s share was $32.0 million.

During the year ended December 31, 2017, we purchased a total of 4,023,726 of our common shares for $100.5 million at an average price per share of $24.97. The Board of Directors has authorized the purchase of up to 25,000,000 common shares, which may be made from time to time in the open market, through block trades or otherwise. As of December 31, 2017, 12,500,000 common shares remain authorized for repurchase.

In February 2009, the Board of Directors authorized, from time to time, the purchase of our outstanding debt securities through cash purchases in open market transactions, privately negotiated transactions or otherwise. Such repurchases, if any, depend upon prevailing market conditions, our liquidity requirements and other factors; such purchases may be commenced or suspended at any time without notice.

Looking forward to 2018, we anticipate an increase in our parent company liquidity. On January 11, 2018, the Board of Directors of Jefferies approved both a distribution of $200 million to Leucadia, which was received on January 31, 2018, and a policy authorizing Jefferies to pay a quarterly distribution to Leucadia equal to 50% of its net earnings. In addition to these distributions, we anticipate receiving payments under the tax sharing agreement between Jefferies and Leucadia. Because of the inherent difficulty in estimating future earnings and future taxable income, it is difficult to project the amounts we will ultimately receive.

Concentration, Liquidity and Leverage Targets

From time to time in the past, we have accessed public and private credit markets and raised capital in underwritten bond financings. The funds raised have been used by us for general corporate purposes, including for our existing businesses and new investment opportunities. In addition, the ratings of Leucadia are a factor considered by rating agencies that rate the debt of our subsidiary companies, including Jefferies, whose access to external financing is important to its day to day operations. Ratings issued by bond rating agencies, subject to change at any time, are as follows:

	Rating	Outlook
Moody’s Investors Service	Ba1	Rating Under Review
Standard and Poor’s	BBB-	Stable
Fitch Ratings	BBB	Stable

We target specific concentration, leverage and liquidity principles, expressed in the form of certain ratios and percentages, although there is no legal requirement to do so.

Concentration Target: As a diversification measure, we limit cash investments such that our single largest investment does not exceed 20% of equity excluding Jefferies, and that our next largest investment does not exceed 10% of equity excluding Jefferies, in each case measured at the time the investment was made. National Beef is our largest investment and HRG is our next largest investment. There were no investments made during the year that approached 10% of equity excluding Jefferies.

42

Liquidity Target: We hold a liquidity reserve calculated as a minimum of twenty-four months of holding company expenses (excluding non-cash components), parent company interest and dividends. Maturities of parent company debt within the upcoming year are also included in the target; however, our next maturity is during 2023 so there is no current inclusion.

Liquidity reserve (in thousands):
Minimum reserve under liquidity target	$	544,600
Actual liquidity	$	1,325,384

Leverage Target: We target a maximum parent debt to stressed equity ratio of .50, with stressed equity defined as equity (excluding Jefferies) assuming the loss of our two largest investments.

Consolidated Statements of Cash Flows

As discussed above, we have historically relied on our available liquidity to meet short-term and long-term needs, and to make acquisitions of new businesses and investments.  Except as otherwise disclosed herein, our operating businesses do not generally require significant funds to support their operating activities, and we do not depend on positive cash flow from our operating segments to meet our liquidity needs.  The mix of our operating businesses and investments can change frequently as a result of acquisitions or divestitures, the timing of which is impossible to predict but which often have a significant impact on our Consolidated Statements of Cash Flows in any one period.  Further, the timing and amounts of distributions from investments in associated companies may be outside our control.  As a result, reported cash flows from operating, investing and financing activities do not generally follow any particular pattern or trend, and reported results in the most recent period should not be expected to recur in any subsequent period.

Net cash of $1,072.8 million and $608.8 million, respectively, was provided by operating activities in 2017 and 2016 and net cash of $761.8 million was used for operating activities in 2015. 

• Jefferies generated funds of $762.5 million during 2017 and used funds of $132.1 million and $294.5 million during 2016 and 2015, respectively. Included in these amounts are distributions received from associated companies of $21.0 million during 2017, $38.2 million during 2016 and $76.7 million during 2015.

• National Beef generated funds of $553.8 million, $484.8 million and $76.5 million during 2017, 2016 and 2015, respectively.

• Within our Other Financial Services Businesses and Investments, cash of $124.6 million, $50.0 million and $325.0 million was used during 2017, 2016 and 2015, respectively, to make additional investments in the Leucadia Asset Management

43

platform. During 2016, cash of $257.0 million was generated from our trading portfolio and $170.0 million from our investments in managed funds related to our Leucadia Asset Management platform. We received distributions from Berkadia, an associated company, of $66.7 million during 2017, $99.9 million during 2016 and $89.4 million during 2015. Cash used for operating activities also includes net cash used of $131.3 million in 2017, $119.8 million in 2016 and $140.2 million in 2015 relating to automobile installment contracts, which is reflected in the net change in other receivables.

• Within our Other Merchant Banking Businesses and Investments, manufacturing generated funds of $15.7 million in 2017, $35.4 million in 2016 and $31.2 million in 2015. We received distributions from Garcadia, an associated company, of $46.9 million during 2017, $51.4 million during 2016 and $57.3 million during 2015. Net losses related to real estate, property and equipment, and other assets include impairment charges of $10.1 million in 2017, $65.7 million in 2016 and $27.7 million in 2015, primarily related to JETX.

• Within our Corporate and Other Businesses and Investments, cash of $47.6 million was used to make additional investments in our trading portfolio and $50.0 million was used to make an additional investment in a managed fund during 2017. Net losses related to real estate, property and equipment, and other assets include the write down of a note receivable of $20.0 million related to the sale of a subsidiary in 2012.

• Our cash used for operating activities also reflects the use of $7.3 million during 2015 by our discontinued operations. Additionally, during 2015, we paid $80.4 million in connection with legal settlements. The change in operating cash flows also reflects greater interest payments during 2017 as compared to 2016 and lower interest payments in 2016 as compared to 2015.

Net cash of $47.3 million and $639.7 million, respectively, was used for investing activities in 2017 and 2016 and net cash of $781.2 million was provided by investing activities in 2015. 

• Acquisitions of property, equipment and leasehold improvements, and other assets related to Jefferies include $72.7 million in 2017, $103.3 million in 2016 and $68.8 million in 2015. Jefferies made loans to and investments in associated companies of $3,161.6 million during 2017, $538.2 million during 2016 and $1,438.7 million during 2015. Jefferies received capital distributions and loan repayments from its associated companies of $3,069.0 million during 2017, $689.2 million during 2016 and $1,384.9 million during 2015. Additionally, Jefferies received proceeds of $173.1 million during 2017 from the sale of its investment in Jefferies LoanCore.

• Acquisitions of property, equipment and leasehold improvements, and other assets related to National Beef include $70.4 million in 2017, $62.0 million in 2016 and $48.6 million in 2015.

• Within our Other Financial Services Businesses and Investments, acquisitions of property, equipment and leasehold improvements, and other assets were $1.2 million in 2017, $48.6 million in 2016 and $53.0 million in 2015. Advances on notes, loans and other receivables during 2017 and 2016 primarily relate to real estate projects in 54 Madison and during 2015 include the investment in FXCM ($279.0 million). Collections on notes, loans and other receivables during 2017 and 2016 include $139.1 million and $24.6 million, respectively, related to real estate projects in 54 Madison and $114.9 million and $72.1 million, respectively, related to FXCM.

Amounts related to our U.S. pension obligations ($60.5 million) are not included in the above table as the timing of payments is uncertain; however, we do expect to make $8.9 million of contributions to these plans in 2018. For further information, see Note 19 in our consolidated financial statements. In addition, the above amounts do not include liabilities for unrecognized tax benefits as the timing of payments, if any, is uncertain. Such amounts aggregated $226.4 million at December 31, 2017; for more information, see Note 20 in our consolidated financial statements.

Our U.S. pension obligations relate to frozen defined benefit pension plans, principally the defined benefit plan of WilTel Communications Group, LLC, our former telecommunications subsidiary. When we sold WilTel in 2005, its defined benefit pension plan was not transferred in connection with the sale. At December 31, 2017, we had recorded a liability of $52.8 million in our Consolidated Statement of Financial Condition for WilTel’s unfunded defined benefit pension plan obligation. This amount represents the difference between the present value of amounts owed to former employees of WilTel (referred to as the projected benefit obligation) and the market value of plan assets set aside in segregated trust accounts. Since the benefits in this plan have been frozen, future changes to the unfunded benefit obligation are expected to principally result from benefit payments, changes in the market value of plan assets, differences between actuarial assumptions and actual experience and interest rates.

Calculations of pension expense and projected benefit obligations are prepared by actuaries based on assumptions provided by management. These assumptions are reviewed on an annual basis, including assumptions about discount rates, interest credit rates

45

and expected long-term rates of return on plan assets. The timing of expected future benefit payments was used in conjunction with the Citigroup Pension Discount Curve to develop a discount rate for the WilTel plan that is representative of the high quality corporate bond market. Holding all other assumptions constant, a 0.25% change in the discount rate would affect pension expense in 2018 by $0.2 million and the benefit obligation by $6.0 million, of which $4.4 million relates to the WilTel plan.

The deferred losses in accumulated other comprehensive income (loss) have not yet been recognized as components of net periodic pension cost in the Consolidated Statements of Operations ($51.3 million at December 31, 2017). These deferred amounts primarily result from differences between the actual and assumed return on plan assets and changes in actuarial assumptions, including changes in discount rates and changes in interest credit rates. They are amortized to expense if they exceed 10% of the greater of the projected benefit obligation or the market value of plan assets as of the beginning of the year. The estimated net loss that will be amortized from accumulated other comprehensive income (loss) into pension expense in 2018 is $2.5 million.

The assumed long-term rates of return on plan assets are based on the investment objectives of the plans, which are more fully discussed in Note 19 in our consolidated financial statements.

Jefferies Liquidity

General

The Chief Financial Officer and Global Treasurer of Jefferies are responsible for developing and implementing liquidity, funding and capital management strategies for the Jefferies businesses. These policies are determined by the nature and needs of day to day business operations, business opportunities, regulatory obligations, and liquidity requirements.

The actual levels of capital, total assets, and financial leverage are a function of a number of factors, including asset composition, business initiatives and opportunities, regulatory requirements and cost and availability of both long-term and short-term funding.  Jefferies has historically maintained a balance sheet consisting of a large portion of total assets in cash and liquid marketable securities, arising principally from traditional securities brokerage and trading activity. The liquid nature of these assets provides flexibility in financing and managing Jefferies business.

A business unit level balance sheet and cash capital analysis is prepared and reviewed with senior management on a weekly basis.  As a part of this balance sheet review process, capital is allocated to all assets and gross balance sheet limits are adjusted, as necessary. This process ensures that the allocation of capital and costs of capital are incorporated into business decisions. The goals of this process are to protect the Jefferies platform, enable the businesses to remain competitive, maintain the ability to manage capital proactively and hold businesses accountable for both balance sheet and capital usage.

Jefferies actively monitors and evaluates its financial condition and the composition of its assets and liabilities. The overall securities inventory is continually monitored by Jefferies, including the inventory turnover rate, which confirms the liquidity of overall assets. Substantially all of Jefferies trading assets and trading liabilities are valued on a daily basis and Jefferies monitors and employs balance sheet limits for its various businesses. In connection with the government and agency fixed income business and Jefferies role as a primary dealer in these markets, a sizable portion of its securities inventory is comprised of U.S. government and agency securities and other G-7 government securities. For further detail on Jefferies outstanding sovereign exposure, refer to Quantitative and Qualitative Disclosures about Market Risk below.

At December 31, 2017, our Consolidated Statement of Financial Condition includes Jefferies Level 3 trading assets that are approximately 2.1% of total trading assets.

Securities financing assets and liabilities include both financing for financial instruments trading activity, matched book transactions and mortgage finance transactions. Matched book transactions accommodate customers, as well as obtain securities for the settlement and financing of inventory positions.

The following table presents Jefferies period end balance, average balance and maximum balance at any month end within the periods presented for Securities purchased under agreements to resell and Securities sold under agreements to repurchase (in millions):

	Year Ended December 31, 2017		Year Ended December 31, 2016
Securities purchased under agreements to resell:
Period end	$	3,690	$	3,862
Month end average	6,195		5,265
Maximum month end	7,814		7,001
Securities sold under agreements to repurchase:
Period end	$	8,661	$	6,792
Month end average	11,273		11,410
Maximum month end	13,679		16,620

Fluctuations in the balance of Jefferies repurchase agreements from period to period and intraperiod are dependent on business activity in those periods. Additionally, the fluctuations in the balances of Jefferies securities purchased under agreements to resell over the periods presented are influenced in any given period by its clients’ balances and its clients' desires to execute collateralized financing arrangements via the repurchase market or via other financing products. Average balances and period end balances will fluctuate based on market and liquidity conditions and Jefferies considers the fluctuations intraperiod to be typical for the repurchase market.

Liquidity Management

The key objectives of Jefferies liquidity management framework are to support the successful execution of its business strategies while ensuring sufficient liquidity through the business cycle and during periods of financial distress. The liquidity management policies are designed to mitigate the potential risk that adequate financing may not be accessible to service financial obligations without material franchise or business impact.

The principal elements of Jefferies liquidity management framework are the Contingency Funding Plan, the Cash Capital Policy and the assessment of Maximum Liquidity Outflow.

Contingency Funding Plan. The Jefferies Contingency Funding Plan is based on a model of a potential liquidity contraction over a one year time period. This incorporates potential cash outflows during a liquidity stress event, including, but not limited to, the following:

• Repayment of all unsecured debt maturing within one year and no incremental unsecured debt issuance;

• Maturity rolloff of outstanding letters of credit with no further issuance and replacement with cash collateral;

• Higher margin requirements than currently exist on assets on securities financing activity, including repurchase agreements;

• Liquidity outflows related to possible credit downgrade;

• Lower availability of secured funding;

• Client cash withdrawals;

• The anticipated funding of outstanding investment and loan commitments; and

• Certain accrued expenses and other liabilities and fixed costs.

Cash Capital Policy. A cash capital model is maintained that measures long-term funding sources against requirements. Sources of cash capital include equity and the noncurrent portion of long-term borrowings. Uses of cash capital include the following:

• Illiquid assets such as equipment, goodwill, net intangible assets, exchange memberships, deferred tax assets and certain investments;

• A portion of securities inventory that is not expected to be financed on a secured basis in a credit stressed environment (i.e., margin requirements); and

• Drawdowns of unfunded commitments. 

47

To ensure that Jefferies does not need to liquidate inventory in the event of a funding crisis, Jefferies seeks to maintain surplus cash capital, which is reflected in the leverage ratios Jefferies maintains. Jefferies total long-term capital of $11.2 billion at December 31, 2017 exceeded its cash capital requirements.

Maximum Liquidity Outflow. Jefferies businesses are diverse, and liquidity needs are determined by many factors, including market movements, collateral requirements and client commitments, all of which can change dramatically in a difficult funding environment. During a liquidity crisis, credit-sensitive funding, including unsecured debt and some types of secured financing agreements, may be unavailable, and the terms (e.g., interest rates, collateral provisions and tenor) or availability of other types of secured financing may change. As a result of Jefferies policy to ensure it has sufficient funds to cover estimates of what may be needed in a liquidity crisis, Jefferies holds more cash and unencumbered securities and has greater long-term debt balances than the businesses would otherwise require. As part of this estimation process, Jefferies calculates a Maximum Liquidity Outflow that could be experienced in a liquidity crisis. Maximum Liquidity Outflow is based on a scenario that includes both market-wide stress and firm-specific stress.

Based on the sources and uses of liquidity calculated under the Maximum Liquidity Outflow scenarios Jefferies determines, based on its calculated surplus or deficit, additional long-term funding that may be needed versus funding through the repurchase financing market and considers any adjustments that may be necessary to Jefferies inventory balances and cash holdings. Jefferies has sufficient excess liquidity to meet all contingent cash outflows detailed in the Maximum Liquidity Outflow. Jefferies regularly refines its model to reflect changes in market or economic conditions and the firm’s business mix.

Sources of Liquidity

Within Jefferies, the following are financial instruments that are cash and cash equivalents or are deemed by Jefferies management to be generally readily convertible into cash, marginable or accessible for liquidity purposes within a relatively short period of time, as reflected in our Consolidated Statements of Financial Condition (in thousands):

	December 31, 2017		Average Balance  Fourth Quarter 2017 (1)		December 31, 2016
Cash and cash equivalents:

Total cash and cash equivalents and other liquidity sources	$	6,709,037	$	5,544,181	$	5,303,501

(1) Average balances are calculated based on weekly balances.

(2) Consists of high quality sovereign government securities and reverse repurchase agreements collateralized by U.S. government securities and other high quality sovereign government securities; deposits with a central bank within the European Economic Area, Canada, Australia, Japan, Switzerland or the U.S.; and securities issued by a designated multilateral development bank and reverse repurchase agreements with underlying collateral comprised of these securities.

(3) Other includes unencumbered inventory representing an estimate of the amount of additional secured financing that could be reasonably expected to be obtained from financial instruments owned that are currently not pledged after considering reasonable financing haircuts.

In addition to the cash balances and liquidity pool presented above, the majority of trading assets and liabilities are actively traded and readily marketable. Repurchase financing can be readily obtained for approximately 72.8% of Jefferies inventory at haircuts

48

of 10% or less, which reflects the liquidity of the inventory. In addition, as a matter of Jefferies policy, all of these assets have internal capital assessed, which is in addition to the funding haircuts provided in the securities finance markets. Additionally, certain of Jefferies trading assets primarily consisting of bank loans, consumer loans and investments are predominantly funded by Jefferies long-term capital. Under Jefferies cash capital policy, capital allocation levels are modeled that are more stringent than the haircuts used in the market for secured funding; and surplus capital is maintained at these more stringent levels. Jefferies continually assesses the liquidity of its inventory based on the level at which Jefferies could obtain financing in the marketplace for a given asset. Assets are considered to be liquid if financing can be obtained in the repurchase market or the securities lending market at collateral haircut levels of 10% or less. The following summarizes Jefferies trading assets by asset class that are considered to be of a liquid nature and the amount of such assets that have not been pledged as collateral as reflected in the Consolidated Statements of Financial Condition (in thousands):

	December 31, 2017				December 31, 2016
	Liquid Financial  Instruments		Unencumbered Liquid Financial  Instruments (2)		Liquid Financial  Instruments		Unencumbered Liquid Financial  Instruments (2)
Corporate equity securities	$	1,718,617	$	272,380	$	1,815,819	$	280,733
Corporate debt securities	2,475,291		57,290		1,818,150		—
U.S. Government, agency and municipal securities	1,954,697		185,481		3,157,737		600,456

Agency mortgage-backed securities (1)	1,742,977		—		1,090,391		—
Loans and other receivables	243,664		—		274,842		—
	$	10,186,188	$	1,511,572	$	10,414,974	$	1,736,131

(1) Consists solely of agency mortgage-backed securities issued by Freddie Mac, Fannie Mae and Ginnie Mae. These securities include pass-through securities, securities backed by adjustable rate mortgages (“ARMs”), collateralized mortgage obligations, commercial mortgage-backed securities and interest- and principal-only securities.

(2) Unencumbered liquid balances represent assets that can be sold or used as collateral for a loan, but have not been.

In addition to being able to be readily financed at modest haircut levels, it is estimated that each of the individual securities within each asset class above could be sold into the market and converted into cash within three business days under normal market conditions, assuming that the entire portfolio of a given asset class was not simultaneously liquidated. There are no restrictions on the unencumbered liquid securities, nor have they been pledged as collateral.

Sources of Funding

Secured Financing

Readily available secured funding is used to finance Jefferies financial instruments inventory. The ability of Jefferies to support increases in total assets is largely a function of the ability to obtain short and intermediate term secured funding, primarily through securities financing transactions. Repurchase or reverse repurchase agreements (collectively "repos"), respectively, are used to finance a portion of long inventory and cover a portion of short inventory through pledging and borrowing securities. Approximately 74.4% of Jefferies cash and non-cash repurchase financing activities use collateral that is considered eligible collateral by central clearing corporations. Central clearing corporations are situated between participating members who borrow cash and lend securities (or vice versa); accordingly, repo participants contract with the central clearing corporation and not one another individually. Therefore, counterparty credit risk is borne by the central clearing corporation which mitigates the risk through initial margin demands and variation margin calls from repo participants. The comparatively large proportion of Jefferies total repo activity that is eligible for central clearing reflects the high quality and liquid composition of its trading inventory. For those asset classes not eligible for central clearinghouse financing, bi-lateral financings are sought on an extended term basis and the tenor of Jefferies repurchase and reverse repurchase agreements generally exceeds the expected holding period of the assets Jefferies is financing. The weighted average maturity of cash and non-cash repurchase agreements for non-clearing corporation eligible funded inventory is approximately three months. 

Jefferies ability to finance inventory via central clearinghouses and bi-lateral arrangements is augmented by Jefferies ability to draw bank loans on an uncommitted basis under various banking arrangements. As of December 31, 2017, short-term borrowings

49

which must be repaid within one year or less and include bank loans and overdrafts, borrowings under revolving credit facilities and structured notes, totaled $436.2 million. Interest under the bank lines is generally at a spread over the federal funds rate. Letters of credit are used in the normal course of business mostly to satisfy various collateral requirements in favor of exchanges in lieu of depositing cash or securities. Average daily short-term borrowings for Jefferies for 2017 and 2016 were $482.4 million and $399.6 million, respectively.

Jefferies short-term borrowings include an Intraday Credit Facility, whereby the Bank of New York Mellon agrees to make revolving intraday credit advances for an aggregate committed amount of $150.0 million. The Intraday Credit Facility contains a financial covenant, which includes a minimum regulatory net capital requirement for its U.S. broker-dealer. Interest is based on the higher of the Federal funds effective rate plus 0.5% or the prime rate. At December 31, 2017, Jefferies was in compliance with all debt covenants under the Intraday Credit Facility.

In addition to the above financing arrangements, Jefferies issues notes backed by eligible collateral under a master repurchase agreement, which provides an additional financing source for its inventory (“repurchase agreement financing program”). The outstanding amount of the notes issued under the program was $722.1 million in aggregate, which is presented within Other secured financings in the Consolidated Statement of Financial Condition at December 31, 2017. All of the notes bear interest at a spread over one month LIBOR. Of the $722.1 million aggregate notes, $164.0 million matures in May 2018, but is currently redeemable at the option of the noteholders; $97.4 million matures in February 2018; $101.3 million matures in July 2018, but is currently redeemable at Jefferies option or the option of the noteholders; $74.4 million matures in July 2018; $125.0 million matures in August 2018, but is currently redeemable at Jefferies option or the option of the noteholders; and $160.0 million matures in November 2018, but is currently redeemable at Jefferies option. 

Long-Term Debt

Jefferies long-term debt reflected in the Consolidated Statement of Financial Condition at December 31, 2017 is $6.4 billion.  Jefferies long-term debt has a weighted average maturity of approximately seven years. Jefferies next scheduled maturity is the $678.3 million principal amount of 5.125% Senior Notes that mature in April 2018.

Jefferies long-term debt ratings are as follows:

	Rating	Outlook
Moody’s Investors Service	Baa3	Stable
Standard and Poor’s	BBB-	Stable
Fitch Ratings	BBB	Stable

Jefferies access to external financing to finance its day to day operations, as well as the cost of that financing, is dependent upon various factors, including its debt ratings. Jefferies current debt ratings are dependent upon many factors, including industry dynamics, operating and economic environment, operating results, operating margins, earnings trend and volatility, balance sheet composition, liquidity and liquidity management, capital structure, overall risk management, business diversification and market share and competitive position in the markets in which it operates. Deteriorations in any of these factors could impact Jefferies credit ratings. While certain aspects of a credit rating downgrade are quantifiable pursuant to contractual provisions, the impact on its business and trading results in future periods is inherently uncertain and depends on a number of factors, including the magnitude of the downgrade, the behavior of individual clients and future mitigating action taken by Jefferies.

In connection with certain OTC derivative contract arrangements and certain other trading arrangements, Jefferies may be required to provide additional collateral to counterparties, exchanges and clearing organizations in the event of a credit rating downgrade. The amount of additional collateral that could be called by counterparties, exchanges and clearing organizations under the terms of such agreements in the event of a downgrade of Jefferies long-term credit rating below investment grade was $48.5 million. For certain foreign clearing organizations, credit rating is only one of several factors employed in determining collateral that could be called. The above represents management’s best estimate for additional collateral to be called in the event of credit rating downgrade. The impact of additional collateral requirements is considered in Jefferies Contingency Funding Plan and calculation of Maximum Liquidity Outflow, as described above.

Ratings issued by credit rating agencies are subject to change at any time.

Net Capital

Jefferies operates a broker-dealer registered with the SEC and member firms of FINRA. Jefferies LLC is subject to the Securities and Exchange Commission Uniform Net Capital Rule ("Rule 15c3-1"), which requires the maintenance of minimum net capital and has elected to calculate minimum capital requirements using the alternative method permitted by Rule 15c3-1 in calculating net capital. Jefferies, as a dually-registered U.S. broker-dealer and FCM, is also subject to Rule 1.17 of the CFTC which sets forth minimum financial requirements. The minimum net capital requirement in determining excess net capital for a dually-registered U.S. broker-dealer and FCM is equal to the greater of the requirement under Rule 15c3-1 or CFTC Rule 1.17. In November 2017, Jefferies Execution Services, Inc. merged with and into Jefferies LLC, with Jefferies LLC as the surviving entity.

Jefferies LLC’s net capital and excess net capital as of December 31, 2017 were $1,418.9 million and $1,330.2 million, respectively.

FINRA is the designated examining authority for Jefferies U.S. broker-dealer and the NFA is the designated self-regulatory organization for Jefferies as an FCM.

Certain other U.S. and non-U.S. subsidiaries of Jefferies are subject to capital adequacy requirements as prescribed by the regulatory authorities in their respective jurisdictions, including Jefferies International Limited which is subject to the regulatory supervision and requirements of the Financial Conduct Authority in the United Kingdom. The Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") was signed into law on July 21, 2010. The Dodd-Frank Act contains provisions that require the registration of all swap dealers, major swap participants, security-based swap dealers, and/or major security-based swap participants. While entities that register under these provisions will be subject to regulatory capital requirements, these regulatory capital requirements have not yet been finalized. Jefferies expects that these provisions will result in modifications to the regulatory capital requirements of some of its entities, and will result in some of its other entities becoming subject to regulatory capital requirements for the first time, including Jefferies Financial Services, Inc., which registered as a swap dealer with the CFTC during January 2013 and Jefferies Financial Products LLC, which registered during August 2014.

The regulatory capital requirements referred to above may restrict Jefferies ability to withdraw capital from its regulated subsidiaries. Some of our other consolidated subsidiaries also have credit agreements which may restrict the payment of cash dividends, or the ability to make loans or advances to the parent company.

We have agreed to reimburse Berkshire Hathaway for up to one-half of any losses incurred under a $1.5 billion surety policy securing outstanding commercial paper issued by an affiliate of Berkadia. As of December 31, 2017, the aggregate amount of commercial paper outstanding was $1.47 billion. This commitment is not included in the table above as the timing of payments, if any, is uncertain.

In the normal course of business Jefferies and certain other subsidiaries engage in other off-balance sheet arrangements, including derivative contracts. Neither derivatives’ notional amounts nor underlying instrument values are reflected as assets or liabilities in the Consolidated Statements of Financial Condition. Rather, the fair values of derivative contracts are reported in the Consolidated Statements of Financial Condition as Trading assets – Derivative contracts or Trading liabilities – Derivative contracts as applicable.  Derivative contracts are reflected net of cash paid or received pursuant to credit support agreements and are reported on a net by counterparty basis when a legal right of offset exists under an enforceable master netting agreement. For additional information about our accounting policies and our derivative activities see Notes 2, 4 and 5 in our consolidated financial statements.

We are routinely involved with variable interest entities (“VIEs”) in the normal course of business. At December 31, 2017, we did not have any commitments to purchase assets from our VIEs. For additional information regarding VIEs, see Notes 7 and 9 in our consolidated financial statements.

Critical Accounting Estimates

The preparation of financial statements in accordance with GAAP requires us to make estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Actual results could significantly differ from those estimates. We believe that the following discussion addresses our most critical accounting estimates, which are those that are important to the presentation of our financial condition and results of operations and require our most difficult, subjective and complex judgments.

Income Taxes – We record a valuation allowance to reduce our net deferred tax asset to the amount that is more likely than not to be realized. If in the future we determine that it is more likely than not that we will be able to realize our net deferred tax asset in excess of our recorded amount, an adjustment to increase the net deferred tax asset would increase income in such period. If in the future we were to determine that we would not be able to realize all or part of its recorded net deferred tax asset, an adjustment to decrease the net deferred tax asset would be charged to income in such period. We are required to consider all available evidence, both positive and negative, and to weigh the evidence when determining whether a valuation allowance is required and the amount of such valuation allowance. Generally, greater weight is required to be placed on objectively verifiable evidence when making this assessment, in particular on recent historical operating results.

Our estimate of future taxable income considers all available evidence, both positive and negative, about our operating businesses and investments, includes an aggregation of individual projections for each significant operating business and investment, estimated apportionment factors for state and local taxing jurisdictions and includes all future years that we estimate we will have available NOLs. As discussed further in Note 20, Federal NOLs begin to expire in 2023, with a substantial amount expiring between 2023 and 2025. We believe that our estimate of future taxable income is reasonable but inherently uncertain, and if our current or future operations and investments generate taxable income different than the projected amounts, further adjustments to the valuation allowance are possible. The current balance of the deferred tax valuation allowance principally reserves for NOLs of certain subsidiaries that are not available to offset income generated by other members of the consolidated tax return group.

We also record reserves for unrecognized tax benefits based on our assessment of the probability of successfully sustaining tax filing positions. Management exercises significant judgment when assessing the probability of successfully sustaining tax filing positions, and in determining whether a contingent tax liability should be recorded and if so estimating the amount. If our tax filing positions are successfully challenged, payments could be required that are in excess of reserved amounts or we may be required to reduce the carrying amount of our net deferred tax asset, either of which could be significant to our Consolidated Statement of Financial Condition or results of operations.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Act. The Tax Act makes broad and complex changes to the U.S. tax code that will impact many areas of taxation, including, but not limited to, (1) reduction of the U.S. federal corporate tax rate from 35% to 21%; (2) elimination of the corporate alternative minimum tax; (3) the introduction of the base erosion anti-abuse tax, a new minimum tax; (4) a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries; (5) a new provision designed to tax global intangible low-taxed income; (6) a new limitation on deductible interest expense; (7) the repeal of the domestic production activity deduction; (8) limitations on the deductibility of certain executive compensation; (9) limitations on the use of foreign tax credits to reduce U.S. income tax liability; (10) limitations on NOLs generated after December 31, 2017, to 80% of taxable income; (11) requiring a one-time transition tax

52

on certain unrepatriated earnings of foreign subsidiaries that is payable over eight years; and (12) bonus depreciation that will allow for full expensing of qualified property.

On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740, Income Taxes. SAB 118 provides a three-step process to be applied at each reporting period to account for and qualitatively disclose: (1) the effects of the change in tax law for which accounting is complete; (2) provisional amounts (or adjustments to provisional amounts) for the effects of the tax law where accounting is not complete, but that a reasonable estimate has been determined: and (3) where a reasonable estimate cannot yet be made and therefore taxes are reflected in accordance with the law prior to the enactment of the Tax Cuts and Jobs Act.

Due to the complex nature of the Tax Act, we have not completed our accounting for the income tax effects of certain elements of the Tax Act. If we were able to make reasonable estimates of the effects of certain elements for which our analysis is not yet complete, we recorded a provisional estimate in the financial statements. If we were not yet able to make reasonable estimates of the impact of certain elements, we have not recorded any adjustments related to those elements and have continued accounting for them in accordance with ASC 740 on the basis of the tax laws in effect before the Tax Act. The ultimate impact of the Tax Act may differ from this estimate, possibly materially, due to changes in interpretations and assumptions, and guidance that may be issued and actions we may take in response to the Tax Act. We note that the Tax Act is complex and we continue to assess the impact that various provisions will have on our business.

Since the Tax Act was passed late in the fourth quarter of 2017, and ongoing guidance and accounting interpretation are expected over the next 12 months, we consider the accounting for the deferred tax asset remeasurements, the transition tax, and other items to be incomplete due to the forthcoming guidance and our ongoing analysis of final year-end data and tax positions. In connection with our initial analysis, we have recorded a discrete tax expense of $450.5 million as a provisional estimate of the impact of the Tax Act during 2017 increasing our effective tax rate by 44.4% to 75.1%. This provisional estimate primarily consists of a $415.0 million expense related to the revaluation of our deferred tax asset and a $35.5 million expense related to the deemed repatriation of foreign earnings.

Fair Value of Financial Instruments – Trading assets and trading liabilities are recorded at fair value, either as required by accounting pronouncements or through the fair value option election. Trading assets and trading liabilities include Jefferies trading activities and financial instruments of other consolidated entities that are accounted for through the fair value option election. Gains and losses on trading assets and trading liabilities are recognized in our Consolidated Statements of Operations. Available for sale securities are reflected at fair value, with unrealized gains and losses reflected as a separate component of equity, net of taxes.  When sold, realized gains and losses on available for sale securities are reflected in the caption Net realized securities gains. Fair value is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price).

In determining fair value, we maximize the use of observable inputs and minimize the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from independent sources. Unobservable inputs reflect our assumptions that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. We apply a hierarchy to categorize our fair value measurements broken down into three levels based on the transparency of inputs as follows:

Level 1:Quoted prices are available in active markets for identical assets or liabilities as of the reported date.

Level 2:Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these financial instruments includes cash instruments for which quoted prices are available but traded less frequently, derivative instruments fair values for which have been derived using model inputs that are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed.

Level 3:Instruments that have little to no pricing observability as of the reported date. These financial instruments are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation.

53

Fair value is a market based measure; therefore, when market observable inputs are not available, our judgment is applied to reflect those judgments that a market participant would use in valuing the same asset or liability. The availability of observable inputs can vary for different products. We use prices and inputs that are current as of the measurement date even in periods of market disruption or illiquidity. The valuation of financial instruments classified in Level 3 of the fair value hierarchy involves the greatest amount of management judgment.

Jefferies Independent Price Verification Group, independent of its trading function, plays an important role in determining that financial instruments are appropriately valued and that fair value measurements are reliable. This is particularly important where prices or valuations that require inputs are less observable. In the event that observable inputs are not available, the control processes are designed to assure that the valuation approach utilized is appropriate and consistently applied and that the assumptions are reasonable. Where a pricing model is used to determine fair value, these control processes include reviews of the pricing model’s theoretical soundness and appropriateness by risk management personnel with relevant expertise who are independent from the trading desks. In addition, recently executed comparable transactions and other observable market data are considered for purposes of validating assumptions underlying the model.

We estimate the fair value of our term loan to FXCM by using valuation models with inputs including management's assumptions concerning the amount and timing of expected cash flows, the loan's implied credit rating and effective yield. We also engaged an independent valuation firm to assist management in estimating the fair value of our equity interest in FXCM in the first quarter of 2017. Our estimate of fair value was based on a discounted cash flow and comparable public company analysis.

For further information on the fair value definition, Level 1, Level 2, Level 3 and related valuation techniques, see Notes 2 and 4 in our consolidated financial statements.

Impairment of Long-Lived Assets – We evaluate our long-lived assets for impairment whenever events or changes in circumstances indicate, in management’s judgment, that the carrying value of such assets may not be recoverable. When testing for impairment, we group our long-lived assets with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities (or asset group). The determination of whether an asset group is recoverable is based on management’s estimate of undiscounted future cash flows directly attributable to the asset group as compared to its carrying value. If the carrying amount of the asset group is greater than the undiscounted cash flows, an impairment loss would be recognized for the amount by which the carrying amount of the asset group exceeds its estimated fair value.

We recorded impairment charges related to long-lived assets of $10.1 million in 2017, $71.1 million in 2016 and $27.7 million in 2015. The 2017 charge related to the write-downs of JETX's unproved oil and gas properties. In the third quarter of 2017, JETX decided to focus on its other higher returning acreage and as a result JETX wrote off the remaining carrying value of $10.1 million for its Houston County acreage. $56.3 million of the 2016 charge related to write-downs of JETX's unproved oil and gas properties and $7.5 million related to the write-down of JETX assets held for sale to fair value. In the third quarter of 2016, JETX curtailed development of its southern acreage in the East Eagle Ford and its Houston County acreage. As a result, an impairment was recorded for the difference between the carrying value and the estimated net realizable value of the acreage. $20.3 million of the 2015 charge related to JETX's oil and gas properties which were impacted by the decline in oil prices.

Impairment of Equity Method Investments – We evaluate equity method investments for impairment when operating losses or other factors may indicate a decrease in value which is other than temporary. We consider a variety of factors including economic conditions nationally and in their geographic areas of operation, adverse changes in the industry in which they operate, declines in business prospects, deterioration in earnings, increasing costs of operations and other relevant factors specific to the investee.  Whenever we believe conditions or events indicate that one of these investments might be significantly impaired, we obtain from such investee updated cash flow projections and impairment analyses of the investee assets. We use this information and, together with discussions with the investee’s management, evaluate if the book value of its investment exceeds its fair value, and if so and the situation is deemed other than temporary, record an impairment charge.

During 2017, we recorded an impairment charge of $130.2 million related to the write-down to fair value of our equity investment in FXCM. As discussed above, we engaged an independent valuation firm to assist management in estimating the fair value of our equity interest in FXCM in the first quarter of 2017. Our estimate of fair value was based on a discounted cash flow and comparable public company analysis. We concluded based on the regulatory actions, FXCM's restructuring plan described further in Note 4, investor perception and declines in the trading price of Global Brokerage's common shares and convertible debt, that the decline in fair value of our equity interest was other than temporary. As such, we impaired our equity investment in FXCM.

Goodwill – We allocate the acquisition cost of consolidated businesses to the specific tangible and intangible assets acquired and liabilities assumed based upon their fair values. Significant judgments and estimates are often made by management to determine these values, and may include the use of appraisals, consideration of market quotes for similar transactions, use of discounted cash

54

flow techniques or consideration of other information we believe to be relevant. Any excess acquisition cost over the fair values of the net assets acquired is recorded as goodwill, which is not amortized to expense. Substantially all of our goodwill was recognized in connection with the Jefferies acquisition.

At least annually, and more frequently if warranted, we assess whether goodwill has been impaired at the reporting unit level. In testing for goodwill impairment, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances lead to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events and circumstances, we conclude that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is not necessary. If we conclude otherwise, we are required to perform the two-step quantitative impairment test. In the first step, the fair value of each reporting unit is compared with its carrying value, including goodwill and allocated intangible assets. If the fair value is in excess of the carrying value, the goodwill for the reporting unit is considered not to be impaired. If the fair value is less than the carrying value then a second step is performed in order to measure the amount of the impairment loss, if any, which is based on comparing the implied fair value of the reporting unit's goodwill to the carrying value.

The fair values are based on valuation techniques that we believe market participants would use, although the valuation process requires significant judgment and often involves the use of significant estimates and assumptions. The methodologies we utilize in estimating fair value include price-to-earnings and price-to-book multiples of comparable public companies and/or projected cash flows. In addition, as the fair values determined under a market approach represent a noncontrolling interest, we applied a control premium to arrive at the estimated fair value of our reporting units on a controlling basis. The estimates and assumptions used in determining fair value could have a significant effect on whether or not an impairment charge is recorded and the magnitude of such a charge. Adverse market or economic events could result in impairment charges in future periods.

An independent valuation specialist was engaged to assist with the valuation process relating to Jefferies for our annual goodwill impairment test as of August 1, 2017. The results of this test indicated the fair value of Jefferies was in excess of the carrying value. However, the valuation methodology is sensitive to comparable company multiples and management's forecasts of future profitability, which comes with a level of uncertainty regarding U.S. and global economic conditions, trading volumes and equity and debt capital market transaction levels. The fair value of our reporting units, including Jefferies, is also impacted by our overall market capitalization. If the future were to differ adversely from these assumptions or there was a sustained decline in our market capitalization, the estimated fair value of Jefferies may decline and result in an impairment. 

Intangible Assets – Intangible assets deemed to have finite lives are generally amortized on a straight-line basis over their estimated useful lives, where the useful life is the period over which the asset is expected to contribute directly, or indirectly, to our future cash flows. Intangible assets are reviewed for impairment on an interim basis when certain events or circumstances exist. If future undiscounted cash flows are estimated to be less than the carrying amounts of the asset groups used to generate those cash flows in subsequent reporting periods, particularly for those with large investments in amortizable intangible assets, impairment charges would have to be recorded.

An intangible asset with an indefinite useful life is not amortized but assessed for impairment annually, or more frequently, when certain events or circumstances exist indicating an assessment for impairment is necessary. Impairment exists when the carrying amount exceeds its fair value. Fair value is determined using valuation techniques consistent with what a market participant would use. All of our indefinite-lived intangible assets were recognized in connection with the Jefferies acquisition, which consists of exchange and clearing organization membership interests and registrations. Our annual impairment testing date is as of August 1, 2017.

Compensation and Benefits – A portion of Jefferies compensation and benefits represents discretionary bonuses, which are finalized at year end. In addition to the level of net revenues, Jefferies overall compensation expense in any given year is influenced by prevailing labor markets, revenue mix, profitability, individual and business performance metrics, and use of share-based compensation programs. We believe the most appropriate way to allocate Jefferies estimated annual total compensation among interim periods is in proportion to projected net revenues earned. Consequently, during the year we accrue Jefferies compensation and benefits based on annual targeted compensation ratios, taking into account the mix of its revenues and the timing of expense recognition.

Contingencies– In the normal course of business, we have been named, from time to time, as a defendant in legal and regulatory proceedings. We are also involved, from time to time, in other exams, investigations and similar reviews (both formal and informal) by governmental and self-regulatory agencies regarding our businesses, certain of which may result in judgments, settlements, fines, penalties or other injunctions.

55

We recognize a liability for a contingency when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. If the reasonable estimate of a probable loss is a range, we accrue the most likely amount of such loss, and if such amount is not determinable, then we accrue the minimum in the range as the loss accrual. The determination of the outcome and loss estimates requires significant judgment on the part of management, can be highly subjective and is subject to significant change with the passage of time as more information becomes available. Estimating the ultimate impact of litigation matters is inherently uncertain, in particular because the ultimate outcome will rest on events and decisions of others that may not be within our power to control. We do not believe that any of our current litigation will have a significant adverse effect on our consolidated financial position, results of operations or liquidity; however, if amounts paid at the resolution of litigation are in excess of recorded reserve amounts, the excess could be significant in relation to results of operations for that period. For further information, see Note 24 in our consolidated financial statements.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

The following includes “forward-looking statements” that involve risk and uncertainties. Actual results could differ materially from those projected in the forward-looking statements. The discussion of risk is presented separately for Jefferies and the balance of our company.  Exclusive of Jefferies, our market risk arises principally from interest rate risk related to our financial instruments owned and equity price risk.

As more fully discussed in Note 4 to our consolidated financial statements, we own approximately 46.6 million common shares of HRG, representing approximately 23% of HRG’s outstanding common shares, which are accounted for under the fair value option and included within Trading assets at fair value of $789.9 million at December 31, 2017. Assuming a decline of 10% in market prices, the value of our investment in HRG could decrease by approximately $79.0 million. Excluding Jefferies and HRG, Financial instruments owned include corporate equity securities with an aggregate fair value of $659.6 million at December 31, 2017. Assuming a decline of 10% in market prices, the value of these investments would decrease by approximately $66.0 million.

Jefferies

The potential for changes in the value of financial instruments is referred to as market risk. Jefferies market risk generally represents the risk of loss that may result from a change in the value of a financial instrument as a result of fluctuations in interest rates, credit spreads, equity prices, commodity prices and foreign exchange rates, along with the level of volatility. Interest rate risks result primarily from exposure to changes in the yield curve, the volatility of interest rates, and credit spreads. Equity price risks result from exposure to changes in prices and volatilities of individual equities, equity baskets and equity indices. Commodity price risks result from exposure to the changes in prices and volatilities of individual commodities, commodity baskets and commodity indices. 

Market risk arises from market making, proprietary trading, underwriting, specialist and investing activities. Jefferies seeks to manage its exposure to market risk by diversifying exposures, controlling position sizes, and establishing economic hedges in related securities or derivatives. Due to imperfections in correlations, gains and losses can occur even for positions that are hedged.  Position limits in trading and inventory accounts are established and monitored on an ongoing basis. Each day, consolidated position and exposure reports are prepared and distributed to various levels of management, which enable management to monitor inventory levels and results of the trading groups.

Value-at-Risk

Within Jefferies, Value-at-Risk ("VaR") is used as a measurement of market risk using a model that simulates revenue and loss distributions on its trading portfolios by applying historical market changes to the current portfolio. Using the results of this simulation, VaR measures the potential loss in value of its financial instruments due to adverse market movements over a specified time horizon at a given confidence level. Jefferies calculates a one-day VaR using a one year look-back period measured at a 95% confidence level.

As with all measures of VaR, the estimate has inherent limitations due to the assumption that historical changes in market conditions are representative of the future. Furthermore, the VaR model measures the risk of a current static position over a one-day horizon and might not capture the market risk of positions that cannot be liquidated or offset with hedges in a one-day period. Published VaR results reflect past trading positions while future risk depends on future positions.

While Jefferies believes the assumptions and inputs in its risk model are reasonable, Jefferies could incur losses greater than the reported VaR because the historical market prices and rates changes may not be an accurate measure of future market events and conditions. Consequently, this VaR estimate is only one of a number of tools Jefferies uses in its daily risk management activities.

56

When comparing the VaR numbers to those of other firms, it is important to remember that different methodologies and assumptions could produce significantly different results.

The following table illustrates each separate component of VaR for each component of market risk by interest rate, equity, currency and commodity products, as well as for Jefferies overall trading positions using the past 365 days of historical data. The aggregated VaR presented here is less than the sum of the individual components (i.e., interest rate risk, foreign exchange rate risk, equity risk and commodity price risk) due to the benefit of diversification among the four risk categories. Diversification benefit equals the difference between aggregated VaR and the sum of VaRs for the four risk categories and arises because the market risk categories are not perfectly correlated. Since we consolidate Jefferies on a one month lag, all amounts reported are for Jefferies annual fiscal periods.

(1) For the VaR numbers reported above, a one-day time horizon, with a one year look-back period, and a 95% confidence level were used.

(2) The diversification effect is not applicable for the maximum and minimum VaR values as the Jefferies VaR and VaR values for the four risk categories might have occurred on different days during the year.

Average daily VaR slightly declined to $7.79 million for the year ended December 31, 2017 from $7.91 million for the year ended December 31, 2016. The slight decline was due to lower equity, currency rate and commodity price risk, partially offset by an increase in interest rate risk and a lower diversification benefit.

The primary method used to test the efficacy of the VaR model is to compare actual daily net revenue for those positions included in the VaR calculation with the daily VaR estimate. This evaluation is performed at various levels of the trading portfolio, from the holding company level down to specific business lines. For the VaR model, trading related revenue is defined as principal transaction revenue, trading related commissions, revenue from securitization activities and net interest income. For a 95% confidence one day VaR model (i.e., no intra-day trading), assuming current changes in market value are consistent with the historical changes used in the calculation, net trading losses would not be expected to exceed the VaR estimates more than twelve times on an annual basis (i.e., once in every 20 days).  During 2017, results of the evaluation at the aggregate level demonstrated no days when the net trading loss exceeded the 95% one day VaR.

Certain positions within financial instruments are not included in the VaR model because VaR is not the most appropriate measure of risk. Accordingly, Jefferies Risk Management has additional procedures in place to assure that the level of potential loss that would arise from market movements are within acceptable levels. Such procedures include performing stress tests, monitoring concentration risk and tracking price target/stop loss levels. The table below presents the potential reduction in net income associated with a 10% stress of the fair value of the positions that are not included in the VaR model at December 31, 2017 (in thousands):

	10% Sensitivity
Private investments	$	15,464
Corporate debt securities in default	13,755
Trade claims	3,141

VaR also excludes the impact of changes in Jefferies own credit spreads on its structured notes for which the fair value option was elected. The estimated credit spread risk sensitivity for each one basis point widening in Jefferies own credit spreads on financial

57

liabilities for which the fair value option was elected was an increase in value of approximately $0.7 million at December 31, 2017.

There were 14 days with trading losses out of a total of 252 trading days in 2017.

Scenario Analysis and Stress Tests

While VaR measures potential losses due to adverse changes in historical market prices and rates, Jefferies uses stress testing to analyze the potential impact of specific events or moderate or extreme market moves on its current portfolio both firm wide and within business segments. Stress scenarios comprise both historical market price and rate changes and hypothetical market environments, and generally involve simultaneous changes of many risk factors. Indicative market changes in Jefferies scenarios include, but are not limited to, a large widening of credit spreads, a substantial decline in equities markets, significant moves in selected emerging markets, large moves in interest rates, changes in the shape of the yield curve and large moves in European markets. In addition, Jefferies also performs ad hoc stress tests and adds new scenarios as market conditions dictate. Because Jefferies stress scenarios are meant to reflect market moves that occur over a period of time, its estimates of potential loss assume some level of position reduction for liquid positions. Unlike Jefferies VaR, which measures potential losses within a given confidence interval, stress scenarios do not have an associated implied probability; rather, stress testing is used to estimate the potential loss from market moves that tend to be larger than those embedded in the VaR calculation.

Stress testing is performed and reported regularly as part of the risk management process. Stress testing is used to assess Jefferies aggregate risk position as well as for limit setting and risk/reward analysis.

Counterparty Credit Risk and Issuer Country Exposure

Counterparty Credit Risk

Credit risk is the risk of loss due to adverse changes in a counterparty’s credit worthiness or its ability or willingness to meet its financial obligations in accordance with the terms and conditions of a financial contract.Jefferies is exposed to credit risk as trading counterparty to other broker-dealers and customers, as a direct lender and through extending loan commitments, as a holder of securities and as a member of exchanges and clearing organizations.

It is critical to Jefferies financial soundness and profitability that Jefferies properly and effectively identify, assess, monitor and manage the various credit and counterparty risks inherent in its businesses. Credit is extended to counterparties in a controlled manner in order to generate acceptable returns, whether such credit is granted directly or is incidental to a transaction. All extensions of credit are monitored and managed on a Jefferies enterprise level in order to limit exposure to loss related to credit risk.

Jefferies employs a Credit Risk Framework, which is responsible for identifying credit risks throughout its operating businesses, establishing counterparty limits and managing and monitoring those credit limits. Jefferies framework includes:

• defining credit limit guidelines and credit limit approval processes;

• providing a consistent and integrated credit risk framework across the enterprise;

• approving counterparties and counterparty limits with parameters set by its Risk Management Committee;

• negotiating, approving and monitoring credit terms in legal and master documentation;

• delivering credit limits to all relevant sales and trading desks;

• maintaining credit reviews for all active and new counterparties;

• operating a control function for exposure analytics and exception management and reporting;

• determining the analytical standards and risk parameters for on-going management and monitoring of global credit risk books;

• actively managing daily exposure, exceptions, and breaches;

• monitoring daily margin call activity and counterparty performance (in concert with the Margin Department); and

• setting the minimum global requirements for systems, reports, and technology.

Jefferies Credit Exposures

Credit exposure exists across a wide-range of products, which includes the following:

• Loans and lending, arising in connection with Jefferies capital markets activities and forward settling traded loans;

• Securities and margin finance, which represents securities financing transactions (reverse repurchase agreements, repurchase agreements and securities lending agreements);

58

• OTC derivatives, which are reported net by counterparty when a legal right of setoff exists under an enforceable master netting agreement, and includes forward settling trades; and

• Cash and cash equivalents, which include both interest-bearing and non-interest bearing deposits at banks.

Current counterparty credit exposures are summarized in the table below and provided by credit quality, region and industry. Credit exposures presented take netting and collateral into consideration by counterparty and master agreement. Collateral taken into consideration includes both collateral received as cash as well as collateral received in the form of securities or other arrangements.  Current exposure is the loss that would be incurred on a particular set of positions in the event of default by the counterparty, assuming no recovery. Current exposure equals the fair value of the positions less collateral. Issuer risk is the credit risk arising from inventory positions (for example, corporate debt securities and secondary bank loans). Issuer risk is included in Jefferies country risk exposure tables below. Of Jefferies counterparty credit exposure at December 31, 2017, excluding cash and cash equivalents, the percentage of exposure from investment grade counterparties increased to 92% from 82% at December 31, 2016, with a majority concentrated in North America.

When comparing Jefferies credit exposure at December 31, 2017 with credit exposure at December 31, 2016, excluding cash and cash equivalents, current exposure increased to approximately $1,353 million from $1,247 million. Counterparty credit exposure increased over the year by 24% from OTC derivatives, primarily driven by investment grade North American banks and broker-

dealers, and by 22% from securities and margin finance, primarily driven by investment grade European banks and broker-dealers. Counterparty credit exposure from Jefferies loans and lending portfolio decreased by 46%, primarily attributed to North American

loans.

The amounts in the tables below are for amounts included in our Consolidated Statements of Financial Condition at December 31, 2017 and 2016 (in millions).

Jefferies Country Risk Exposure

Country risk is the risk that events or developments that occur in the general environment of a country or countries due to economic, political, social, regulatory, legal or other factors, will affect the ability of obligors of the country to honor their obligations.  Jefferies defines the country of risk as the country of jurisdiction or domicile of the obligor.

The following tables reflect Jefferies top exposures to the sovereign governments, corporations and financial institutions in those non-U.S. countries in which there is net long issuer and counterparty exposure, as reflected in our Consolidated Statements of Financial Condition at December 31, 2017 and 2016 (in millions):

Jefferies' net issuer and counterparty risk exposure to Puerto Rico was $29.7 million, as reflected in our Consolidated Statement of Financial Condition at December 31, 2017, is in connection with its municipal securities market-making activities. The government of Puerto Rico is seeking to restructure much of its $73.8 billion in debt on a voluntary basis. At December 31, 2017, Jefferies had no other material exposure to countries where either sovereign or non-sovereign sectors potentially pose potential default risk as the result of liquidity concerns.

Other than our trading portfolio, our financial instrument portfolio is primarily classified as available for sale, and consequently, is recorded at fair value with unrealized gains and losses reflected in equity. Included in our available for sale portfolio are fixed income securities, which comprised approximately 88% of the total available for sale portfolio at December 31, 2017. These fixed income securities are primarily rated “investment grade” or are U.S. governmental agency issued or U.S. Government-Sponsored Enterprises. The estimated weighted average remaining life of these fixed income securities was approximately 0.5 years at December 31, 2017. Our fixed income securities, like all fixed income instruments, are subject to interest rate risk and will fall in value if market interest rates increase. At December 31, 2016, fixed income securities comprised approximately 74% of the total portfolio and had an estimated weighted average remaining life of approximately 0.9 years.

Also included in the available for sale portfolio are equity securities, which are recorded at an aggregate fair value of $88.5 million (aggregate cost of $52.6 million) and which comprised approximately 12% of our total available for sale portfolio at December 31, 2017. We evaluate our portfolio for impairment on a quarterly basis.

We are also subject to interest rate risk on our long-term fixed interest rate debt. Generally, the fair market value of debt securities with a fixed interest rate will increase as interest rates fall, and the fair market value will decrease as interest rates rise. The following table represents principal cash flows by expected maturity dates for our consolidated long-term debt obligations. For the variable rate borrowings, the weighted-average interest rates are based on implied forward rates in the yield curve at the reporting date.  Our market risk with respect to foreign currency exposure on our long-term debt is also shown below.

Item 9A. Controls and Procedures.

Evaluation of disclosure controls and procedures

The Company’s management evaluated, with the participation of the Company’s principal executive and principal financial officers, the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), as of December 31, 2017. Based on their evaluation, the Company’s principal executive and principal financial officers concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2017.

Changes in internal control over financial reporting

There has been no change in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the Company’s fiscal quarter ended December 31, 2017, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

• Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and disposition of the assets of the Company;

• Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

• Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017. In making this assessment, the Company’s management used the criteria set forth in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in 2013.

Based on our assessment and those criteria, management concluded that, as of December 31, 2017, the Company’s internal control over financial reporting was effective.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2017 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which appears herein in Item 8.

Item 9B. Other Information.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Leucadia National Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated statement of financial condition of Leucadia National Corporation and subsidiaries (the "Company") as of December 31, 2017, and the related consolidated statements of operations, comprehensive income (loss), cash flows and changes in equity for the year ended December 31, 2017, and the related notes and schedules listed in the Index at Item 15(a)(2) (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial condition of the Company as of December 31, 2017, and the results of its operations and its cash flows for the year ended December 31, 2017, in conformity with the accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 26, 2018 expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Leucadia National Corporation

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Leucadia National Corporation and subsidiaries (the “Company”) as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements and financial statement schedules as of and for the year ended December 31, 2017, of the Company and our report dated February 26, 2018, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

LEUCADIA NATIONAL CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements

Note 1.  Nature of Operations

Leucadia National Corporation (“Leucadia” or the “Company”) is a diversified holding company focused on long-term value creation to maximize shareholder value. We continuously review acquisitions of businesses, securities and assets that have the potential for significant long-term value creation, invest in a broad array of businesses, and evaluate the retention and disposition of our existing operations and holdings. Changes in the mix of our businesses and investments should be expected.

Our financial services businesses and investments include Jefferies (investment banking and capital markets), Leucadia Asset Management (asset management), Berkadia (commercial mortgage banking, investment sales and servicing), HomeFed (real estate company), FXCM (provider of online foreign exchange trading services) and Foursight Capital (vehicle finance). We also own and have investments in a diverse array of other businesses, including National Beef (beef processing), HRG Group ("HRG") (consumer products), Garcadia (automobile dealerships), Linkem (fixed wireless broadband services in Italy), Vitesse Energy and JETX Energy (oil and gas production and development), Idaho Timber (manufacturing) and Golden Queen (gold and silver mining). The structure of each of our investments was tailored to the unique opportunity each transaction presented. Our investments may be reflected in our consolidated results as consolidated subsidiaries, equity investments, securities or in other ways, depending on the structure of our specific holdings.

Jefferies is the largest independent U.S. headquartered global full-service, integrated securities and investment banking firm. In March 2013, Jefferies became an indirect wholly-owned subsidiary of Leucadia, yet retains a separate credit rating and continues to be a separate SEC reporting company.  Through Jefferies, we own 50% of Jefferies Finance LLC ("Jefferies Finance"), our joint venture with Massachusetts Mutual Life Insurance Company.  Jefferies Finance is a commercial finance company whose primary focus is the origination and syndication of senior secured debt of middle market and growth companies in the form of term and revolving loans. Through Jefferies, we also owned a 48.5% voting interest in Jefferies LoanCore, LLC ("Jefferies LoanCore"), a joint venture with the Government of Singapore Investment Corporation, the Canadian Pension Plan Investment Board and LoanCore, LLC. Jefferies LoanCore originates, purchases and securitizes commercial real estate loans throughout the U.S. On October 31, 2017, Jefferies sold all of its membership interests in Jefferies LoanCore for approximately $173.1 million, the estimated book value as of October 31, 2017. In addition, Jefferies may be entitled to additional cash consideration over the next five years in the event Jefferies LoanCore's yearly return on equity exceeds certain thresholds.

Jefferies has a November 30^th year-end, which it retains for standalone reporting purposes. We reflect Jefferies in our consolidated financial statements utilizing a one month lag. We have reviewed Jefferies business and internal operating results for the month of December 2017 for the purpose of evaluating whether financial statement disclosures or adjustments are required in this Annual Report on Form 10-K, and we have concluded that, other than the effects of the Tax Cuts and Jobs Act of 2017 (the "Tax Act"), no additional disclosures or adjustments are warranted. See Note 20 to our consolidated financial statements for additional information.

Leucadia Asset Management ("LAM") supports and develops focused alternative asset management businesses led by distinct management teams. These include Folger Hill Asset Management LLC ("Folger Hill"), a multi-manager discretionary long/short equity hedge fund platform; Topwater Capital, a first-loss product; CoreCommodity Management LLC, an asset manager that focuses on commodities strategies; Tenacis Capital, a systematic macro investment platform; Lake Hill, an electronic trader in listed options and futures across asset classes; as well as several other smaller businesses. In addition, several investment management businesses, including Jefferies Strategic Investments Division, operate under Jefferies and are included under our marketing of the LAM platform.

Berkadia Commercial Mortgage LLC ("Berkadia"), our 50-50 equity method joint venture with Berkshire Hathaway Inc., provides capital solutions, investment sales advisory and mortgage servicing for multifamily and commercial properties.

We own an approximate 70% equity method interest of HomeFed, which owns and develops residential and mixed use real estate properties. We have contractually agreed to limit our voting rights to 45% of HomeFed's total voting securities voting on any matter. HomeFed is a public company traded on the NASD OTC Bulletin Board.

Our investment in FXCM Group, LLC ("FXCM") and associated companies consist of a senior secured term loan due January 2019, ($69.9 million principal outstanding at December 31, 2017); a 50% voting interest in FXCM and up to 75% of all distributions. FXCM's six-member board is comprised of three directors appointed by Leucadia and three directors appointed by Global Brokerage

F-11

Holdings, LLC ("Global Brokerage Holdings"). See Notes 4 and 10 to our consolidated financial statements for additional information.

We own 100% of Foursight Capital, an auto loan originator and servicer, and 85% of Chrome Capital, which owns and manages a portfolio of leases on used Harley-Davidson motorcycles and is in the process of winding down.

We own 78.9% of National Beef Packing Company. National Beef processes and markets fresh and chilled boxed beef, ground beef, beef by-products, consumer-ready beef and pork, and wet blue leather for domestic and international markets. National Beef operates two beef processing facilities, three consumer-ready processing facilities and a wet blue tanning facility, all located in the U.S. National Beef operates one of the largest wet blue tanning facilities in the world that sells processed hides to tanners that produce finished leather for the automotive, luxury goods, apparel and furniture industries. National Beef owns Kansas City Steak Company, LLC, which sells portioned beef and other products directly to customers through the internet, direct mail and direct response television. National Beef also owns a refrigerated and livestock transportation and logistics company that provides transportation services for National Beef and third parties.

We own approximately 23% of HRG Group, Inc. ("HRG"), a publicly traded company (NYSE: HRG), and we reflect this investment at fair value based on quoted market prices. HRG primarily owns approximately 59% of Spectrum Brands, a publicly traded (NYSE: SPB) global consumer products company. HRG sold its approximate 80% interest in Fidelity & Guaranty Life, a life insurance and annuity products company and 100% interest in Front Street, a long-term reinsurance company to CF Corporation in the fourth quarter of 2017.

Garcadia is an equity method joint venture that owns and operates 28 automobile dealerships in California, Texas, Iowa and Michigan. We own approximately 75% of Garcadia and have board representation and votes equal to the other member of the joint venture.

We own approximately 42% of the common shares of Linkem, as well as convertible preferred shares which, if converted, would increase our ownership to approximately 53% of Linkem's common equity at December 31, 2017. Linkem provides residential broadband services using LTE technologies deployed over the 3.5 GHz spectrum band. Linkem operates in Italy, which has few cable television systems and poor broadband alternatives. Linkem is accounted for under the equity method.

Vitesse Energy, LLC ("Vitesse") is our 96% owned consolidated subsidiary that acquires and develops non-operated working and royalty oil and gas interests in the Bakken Shale oil field in North Dakota and Montana as well as the Denver-Julesburg Basin in Wyoming. JETX Energy, LLC ("JETX"), formerly Juneau Energy, LLC, is our 98% owned consolidated subsidiary that engages in the development and production of oil and gas from onshore, unconventional resource areas. JETX currently has non-operated working interests and acreage in east Texas.

Idaho Timber is our consolidated subsidiary engaged in the manufacture and distribution of various wood products, including the following principal activities:  remanufacturing dimension lumber; remanufacturing, bundling and bar coding of home center boards for large retailers; and production of pine dimension lumber and 5/4” radius-edge, pine decking. 

Golden Queen Mining Company, LLC ("Golden Queen") owns the Soledad Mountain project, an open pit, heap leach gold and silver mining project in Kern County, California, which commenced gold and silver production in March 2016. We and the Clay family have formed and made contributions to a limited liability company, controlled by us, through which we invested in Golden Queen for the development and operation of the project. Our effective ownership of Golden Queen is approximately 35% and is accounted for under the equity method.

Conwed Plastics ("Conwed") was our consolidated subsidiary that manufactured and marketed lightweight plastic netting used for building and construction, erosion and sediment control, packaging, agricultural purposes, carpet padding, filtration, consumer products and other purposes. In January 2017, we sold 100% of Conwed to Schweitzer-Mauduit International, Inc., (NYSE:SWM) for $295 million in cash plus potential earn-out payments in 2019, 2020 and 2021 totaling up to $40 million in cash to the extent the results of Conwed’s subsidiary, Filtrexx International, exceed certain performance thresholds. We recognized a $178.2 million pre-tax gain (net of working capital adjustments) on the sale of Conwed in Other revenues during the year ended December 31, 2017.

Note 2.  Significant Accounting Policies

The preparation of these financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) requires us to make estimates and assumptions that affect the reported amounts in the financial statements and disclosures of contingent assets and liabilities. On an on-going basis, we evaluate all of these estimates and assumptions. The most important of these estimates and assumptions relate to fair value measurements, compensation and benefits, asset impairment, the ability to realize deferred tax assets, the recognition and measurement of uncertain tax positions and contingencies. Although these and other estimates and assumptions are based on the best available information, actual results could be different from these estimates.

Consolidation

Our policy is to consolidate all entities in which we can vote a majority of the outstanding voting stock. In addition, we consolidate entities which meet the definition of a variable interest entity for which we are the primary beneficiary. The primary beneficiary is the party who has the power to direct the activities of a variable interest entity that most significantly impact the entity’s economic performance and who has an obligation to absorb losses of the entity or a right to receive benefits from the entity that could potentially be significant to the entity. We consider special allocations of cash flows and preferences, if any, to determine amounts allocable to noncontrolling interests. All intercompany transactions and balances are eliminated in consolidation.

In situations where we have significant influence, but not control, of an entity that does not qualify as a variable interest entity, we apply either the equity method of accounting or fair value accounting pursuant to the fair value option election under GAAP.  We have also formed nonconsolidated investment vehicles with third-party investors that are typically organized as partnerships or limited liability companies. Our subsidiaries may act as general partner or managing member for these investment vehicles and have generally provided the third-party investors with termination or “kick-out” rights.

Revenue Recognition Policies

Beef Processing and Other Operations

Revenues are recognized when the following conditions are met: (1) collectibility is reasonably assured; (2) title to the product has passed or the service has been rendered and earned; (3) persuasive evidence of an arrangement exists; and (4) there is a fixed or determinable price. National Beef’s revenues are recognized based on the terms of the sale, which for beef processing operations is typically upon delivery to customers. Manufacturing revenues are recognized when title passes.

Investment Banking Activities

Commissions and Other Fees. All customer securities transactions are reported in the Consolidated Statements of Financial Condition on a settlement date basis with related income reported on a trade date basis. We permit institutional customers to allocate a portion of their gross commissions to pay for research products and other services provided by third parties. The amounts allocated for those purposes are commonly referred to as soft dollar arrangements. These arrangements are accounted for on an accrual basis and, as we are not the primary obligor for these arrangements, netted against commission revenues in the Consolidated Statements of Operations. In addition, we earn asset-based fees associated with the management and supervision of assets, account services and administration related to customer accounts.

Principal Transactions. Trading assets and trading liabilities (all of which are recorded on a trade-date basis) are carried at fair value with gains and losses reflected in Principal transaction revenues in the Consolidated Statements of Operations, except for derivatives accounted for as hedges (see Hedge Accounting section, herein and Note 5). Fees received on loans carried at fair value are also recorded within Principal transaction revenues.

Investment Banking.  Underwriting revenues and fees from mergers and acquisitions, restructuring and other investment banking advisory assignments or engagements are recorded when the services related to the underlying transactions are completed under the terms of the assignment or engagement. Expenses associated with such assignments are deferred until reimbursed by the client, the related revenue is recognized or the engagement is otherwise concluded. Expenses are recorded net of client reimbursements and netted against revenues. Unreimbursed expenses with no related revenues are included in Selling, general and administrative expenses in the Consolidated Statements of Operations.

Interest Revenue and Expense.  Interest expense that is deducted from Revenues to arrive at Net revenues is related to Jefferies operations. Contractual interest on Trading assets and Trading liabilities is recognized on an accrual basis as a component of Interest income and Interest expense. Interest flows on derivative trading transactions and dividends are included as part of the

F-13

fair valuation of these contracts and recognized in Principal transactions in the Consolidated Statements of Operations rather than as a component of interest income or expense. Interest on short- and long-term borrowings is recorded on an accrual basis, except for those for which we have elected the fair value option, as Interest expense. Discounts/premiums arising on long-term debt are accreted/amortized to Interest expense using the effective yield method over the remaining lives of the underlying debt obligations. Interest revenue related to Securities borrowed and Securities purchased under agreements to resell activities and interest expense related to Securities loaned and Securities sold under agreements to repurchase activities are recognized on an accrual basis.

Hedge Accounting

Jefferies applies hedge accounting using interest rate swaps designated as fair value hedges of changes in the benchmark interest rate of fixed rate senior long-term debt. Jefferies interest rate swaps are included as derivative contracts in Trading assets and Trading liabilities in the Consolidated Statements of Financial Condition. Jefferies uses regression analysis to perform ongoing prospective and retrospective assessments of the effectiveness of these hedging relationships. A hedging relationship is deemed effective if the change in fair value of the interest rate swap and the change in the fair value of the long-term debt due to changes in the benchmark interest rate offset within a range of 80% to 125%. The impact of valuation adjustments related to Jefferies own credit spreads and counterparty credit spreads are included in the assessment of effectiveness.

For qualifying fair value hedges of benchmark interest rates, the change in the fair value of the derivative and the change in fair value of the long-term debt provide offset of one another, and together with any resulting ineffectiveness, are recorded in Interest expense. See Note 5 for further information.

Cash Equivalents

Cash equivalents include highly liquid investments, including money market funds and certificates of deposit, not held for resale with original maturities of three months or less.

Cash and Securities Segregated and on Deposit for Regulatory Purposes or Deposited With Clearing and Depository Organizations

In accordance with Rule 15c3-3 of the Securities Exchange Act of 1934, Jefferies LLC, as a broker-dealer carrying client accounts, is subject to requirements related to maintaining cash or qualified securities in a segregated reserve account for the exclusive benefit of its clients. Certain other entities are also obligated by rules mandated by their primary regulators to segregate or set aside cash or equivalent securities to satisfy regulations, promulgated to protect customer assets. In addition, certain exchange and/or clearing organizations require cash and/or securities to be deposited by us to conduct day to day activities.

Financial Instruments and Fair Value

Trading assets and Trading liabilities are recorded at fair value, either as required by accounting pronouncements or through the fair value option election. Gains and losses on trading assets and trading liabilities are recognized in our Consolidated Statements of Operations in Principal transactions. Available for sale securities are reflected at fair value, with unrealized gains and losses reflected as a separate component of equity, net of taxes. When sold, realized gains and losses on available for sale securities are reflected in the caption Net realized securities gains. The cost of securities sold is based on average cost. Fair value is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price).

Fair Value Hierarchy

In determining fair value, we maximize the use of observable inputs and minimize the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from independent sources. Unobservable inputs reflect our assumptions that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. We apply a hierarchy to categorize our fair value measurements broken down into three levels based on the transparency of inputs as follows:

Level 1: Quoted prices are available in active markets for identical assets or liabilities as of the reported date. Valuation adjustments and block discounts are not applied to Level 1 instruments.

Level 2: Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these financial instruments includes cash instruments for which quoted prices are available but traded less frequently, derivative instruments fair values for which have been derived using model inputs that are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed.

Level 3: Instruments that have little to no pricing observability as of the reported date. These financial instruments are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation.

Financial instruments are valued at quoted market prices, if available. Certain financial instruments have bid and ask prices that can be observed in the marketplace. For financial instruments whose inputs are based on bid-ask prices, the financial instrument is valued at the point within the bid-ask range that meets our best estimate of fair value. We use prices and inputs that are current as of the measurement date. For financial instruments that do not have readily determinable fair values using quoted market prices, the determination of fair value is based upon consideration of available information, including types of financial instruments, current financial information, restrictions on dispositions, fair values of underlying financial instruments and quotations for similar instruments.

The valuation of financial instruments may include the use of valuation models and other techniques. Adjustments to valuations derived from valuation models may be made when, in management’s judgment, features of the financial instrument such as its complexity, the market in which the financial instrument is traded and risk uncertainties about market conditions require that an adjustment be made to the value derived from the models. Adjustments from the price derived from a valuation model reflect management’s judgment that other participants in the market for the financial instrument being measured at fair value would also consider in valuing that same financial instrument. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment.

The availability of observable inputs can vary and is affected by a wide variety of factors, including, for example, the type of financial instrument and market conditions. As the observability of prices and inputs may change for a financial instrument from period to period, this condition may cause a transfer of an instrument among the fair value hierarchy levels. Transfers among the levels are recognized at the beginning of each period. The degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.

Valuation Process for Financial Instruments

The Jefferies Independent Price Verification ("IPV") Group, which is part of the Jefferies finance department, in partnership with Jefferies Risk Management, is responsible for establishing Jefferies valuation policies and procedures. The IPV Group and Risk Management, which are independent of business functions, play an important role and serve as a control function in determining that Jefferies financial instruments are appropriately reflected at fair value. This is particularly important where prices or valuations that require inputs are less observable. In the event that observable inputs are not available, the control processes are designed to assure that the valuation approach utilized is appropriate and consistently applied and that the assumptions are reasonable. The IPV Group reports to the Jefferies Global Controller and is subject to the oversight of the IPV Committee, which includes senior members of Jefferies finance department and other personnel. Jefferies independent price verification policies and procedures are reviewed, at a minimum, annually and changes to the policies require the approval of the IPV Committee.

Price Testing Process.  Jefferies business units are responsible for determining the fair value of Jefferies financial instruments using approved valuation models and methodologies. In order to ensure that the business unit valuations represent a fair value exit price, the IPV Group tests and validates the fair value of the financial instruments inventory. In the testing process, the IPV Group obtains prices and valuation inputs from sources independent of Jefferies, consistently adheres to established procedures set forth in the valuation policies for sourcing prices and valuation inputs and utilizing valuation methodologies. Sources used to validate fair value prices and inputs include, but are not limited to, exchange data, recently executed transactions, pricing data obtained from third party vendors, pricing and valuation services, broker quotes and observed comparable transactions.

To the extent discrepancies between the business unit valuations and the pricing or valuations resulting from the price testing process are identified, such discrepancies are investigated by the IPV Group and fair values are adjusted, as appropriate. The IPV Group maintains documentation of its testing, results, rationale and recommendations and prepares a monthly summary of its valuation results. This process also forms the basis for the classification of fair values within the fair value hierarchy (i.e., Level 1, Level 2 or Level 3). The IPV Group utilizes the additional expertise of Risk Management personnel in valuing more complex financial instruments and financial instruments with less or limited pricing observability. The results of the valuation testing are

F-15

reported to the IPV Committee on a monthly basis, which discusses the results and determines the financial instrument fair values in the consolidated financial statements. At each quarter end, the overall valuation results, as determined by the IPV Committee, are presented to the Jefferies Audit Committee.

Judgment exercised in determining Level 3 fair value measurements is supplemented by daily analysis of profit and loss performed by the Product Control functions. Gains and losses, which result from changes in fair value, are evaluated and corroborated daily based on an understanding of each trading desk's overall risk positions and developments in a particular market on the given day.  Valuation techniques generally rely on recent transactions of suitably comparable financial instruments and use the observable inputs from those comparable transactions as a validation basis for Level 3 inputs. Level 3 fair value measurements are further validated through subsequent sales testing and market comparable sales, if such information is available. Level 3 fair value measurements require documentation of the valuation rationale applied, which is reviewed for consistency in application from period to period.

Third Party Pricing Information.  Pricing information obtained from external data providers (including independent pricing services and brokers) may incorporate a range of market quotes from dealers, recent market transactions and benchmarking model derived prices to quoted market prices and trade data for comparable securities. External pricing data is subject to evaluation for reasonableness by the IPV Group using a variety of means including comparisons of prices to those of similar product types, quality and maturities, consideration of the narrowness or wideness of the range of prices obtained, knowledge of recent market transactions and an assessment of the similarity in prices to comparable dealer offerings in a recent time period. Jefferies processes challenges the appropriateness of pricing information obtained from external data providers (including independent pricing services and brokers) to validate the data for consistency with the definition of a fair value exit price. Jefferies process includes understanding and evaluating the external data providers’ valuation methodologies. For corporate, U.S. government and agency, municipal debt securities, and loans, to the extent independent pricing services or broker quotes are utilized in Jefferies valuation process, the vendor service providers are collecting and aggregating observable market information as to recent trade activity and active bid-ask submissions. The composite pricing information received from the independent pricing service is thus not based on unobservable inputs or proprietary models. For mortgage- and other asset-backed securities, collateralized debt obligations ("CDOs") and collateralized loan obligations ("CLOs"), the independent pricing services use a matrix evaluation approach incorporating both observable yield curves and market yields on comparable securities as well as implied inputs from observed trades for comparable securities in order to determine prepayment speeds, cumulative default rates and loss severity. Further, Jefferies considers pricing data from multiple service providers as available as well as compares pricing data to prices observed for recent transactions, if any, in order to corroborate valuation inputs.

Model Review Process.  If a pricing model is used to determine fair value, the pricing model is reviewed for theoretical soundness and appropriateness by Risk Management, independent from the trading desks, and then approved by Risk Management to be used in the valuation process. Review and approval of a model for use may include benchmarking the model against relevant third party valuations, testing sample trades in the model, backtesting the results of the model against actual trades and stress-testing the sensitivity of the pricing model using varying inputs and assumptions.  In addition, recently executed comparable transactions and other observable market data are considered for purposes of validating assumptions underlying the model. Models are independently reviewed and validated by Risk Management annually or more frequently if market conditions or use of the valuation model changes.

Investments in Managed Funds

Investments in managed funds include our investments in funds managed by us and our investments in related party managed funds. Investments in nonconsolidated managed funds are accounted for at fair value based on the net asset value (“NAV”) of the funds provided by the fund managers with gains or losses included in the Consolidated Statements of Operations.

Asset management fees and investment income from managed funds include revenues we earn from management, administrative and performance fees from funds and accounts managed by us, revenues from management and performance fees we earn from related-party managed funds and investment income from our investments in these funds. We earn fees in connection with management and investment advisory services performed for various funds and managed accounts. These fees are based on assets under management or an agreed upon notional amount and may include performance fees based upon the performance of the funds. Management and administrative fees are generally recognized over the period that the related service is provided. Generally, performance fees are earned when the return on assets under management exceeds certain benchmark returns, “high-water marks” or other performance targets. Performance fees are accrued (or reversed) on a monthly basis based on measuring performance to date versus any relevant benchmark return hurdles stated in the investment management agreement. Performance fees are not subject to adjustment once the measurement period ends (generally annual periods) and the performance fees have been realized.

F-16

Loans to and Investments in Associated Companies

Loans to and investments in associated companies include investments in private equity and other operating entities in which we exercise significant influence over operating and capital decisions and loans issued in connection with such investments. Loans to and investments in associated companies are accounted for using the equity method. See Note 10 for additional information regarding certain of these investments.

Under the equity method of accounting, our share of the investee’s underlying net income or loss is recorded as Income (loss) related to associated companies, or as part of Other revenues if such investees are considered to be an extension of our business.  Income (loss) for investees for which the fair value option was elected is reported as Principal transactions revenues.

Receivables

At December 31, 2017 and 2016, Receivables include receivables from brokers, dealers and clearing organizations of $2,635.2 million and $2,062.9 million, respectively, and receivables from customers of securities operations of $1,563.8 million and $843.1 million, respectively.

Securities Borrowed and Securities Loaned

Securities borrowed and securities loaned are carried at the amounts of cash collateral advanced and received in connection with the transactions and accounted for as collateralized financing transactions. In connection with both trading and brokerage activities, Jefferies borrows securities to cover short sales and to complete transactions in which customers have failed to deliver securities by the required settlement date, and lend securities to other brokers and dealers for similar purposes. Jefferies has an active securities borrowed and lending matched book business in which it borrows securities from one party and lends them to another party. When Jefferies borrows securities, it generally provides cash to the lender as collateral, which is reflected in the Consolidated Statements of Financial Condition as Securities borrowed. Jefferies earns interest revenues on this cash collateral. Similarly, when Jefferies lends securities to another party, that party provides cash to Jefferies as collateral, which is reflected in the Consolidated Statements of Financial Condition as Securities loaned. Jefferies pays interest expense on the cash collateral received from the party borrowing the securities. The initial collateral advanced or received approximates or is greater than the fair value of the securities borrowed or loaned. Jefferies monitors the fair value of the securities borrowed and loaned on a daily basis and requests additional collateral or returns excess collateral, as appropriate.

Securities Purchased Under Agreements to Resell and Securities Sold Under Agreements to Repurchase

Securities purchased under agreements to resell and Securities sold under agreements to repurchase (collectively "repos") are accounted for as collateralized financing transactions and are recorded at their contracted resale or repurchase amount plus accrued interest. Jefferies earns and incurs interest over the term of the repo, which is reflected in Interest revenue and Interest expense in the Consolidated Statements of Operations on an accrual basis. Repos are presented in the Consolidated Statements of Financial Condition on a net-basis-by counterparty, where permitted by GAAP. The fair value of the underlying securities is monitored daily versus the related receivable or payable balances. Should the fair value of the underlying securities decline or increase, additional collateral is requested or excess collateral is returned, as appropriate.

Property, Equipment and Leasehold Improvements

Property, equipment and leasehold improvements are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization are provided principally on the straight-line method over the estimated useful lives of the assets or, if less, the term of the underlying lease.

Impairment of Long-Lived Assets

We evaluate our long-lived assets for impairment whenever events or changes in circumstances indicate, in management’s judgment, that the carrying value of such assets may not be recoverable. When testing for impairment, we group our long-lived assets with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities (or asset group). The determination of whether an asset group is recoverable is based on management’s estimate of undiscounted future cash flows directly attributable to the asset group as compared to its carrying value. If the carrying amount of the asset group is greater than the undiscounted cash flows, an impairment loss would be recognized for the amount by which the carrying amount of the asset group exceeds its estimated fair value.

F-17

In 2015, we recorded impairment charges in Selling, general and other expenses of $27.7 million, primarily related to a $20.3 million impairment at JETX and an impairment charge related to National Beef's Brawley plant of $4.7 million. For the oil and gas impairment test related to proved properties, we compare expected undiscounted future net cash flows to the unamortized capitalized cost of the asset. If the future undiscounted net cash flows are lower than the unamortized capital cost, we reduce the capitalized cost to fair market value. We used a third party reserve report in which the cash flows were calculated using West Texas Intermediate (oil) and Henry Hub (gas) NYMEX futures prices as of December 31, 2015. For one of our oil fields, the future undiscounted net cash flows were lower than the unamortized capital cost and as a result, we wrote off the total capital cost.

In 2016, JETX recorded impairment charges in Selling, general and other expenses of $56.3 million related to write-downs of unproved oil and gas properties. JETX assesses its unproved oil and gas properties for impairment based on remaining lease terms, drilling results or future plans to develop acreage and they record impairment expense for any decline in value. In the third quarter of 2016, JETX curtailed development of both its southern acreage in the East Eagle Ford and its Houston County acreage. As a result, an impairment was recorded for the difference between the carrying value and the estimated net realizable value of the acreage.

In 2017, JETX decided to focus on its other higher returning acreage and as a result wrote off the remaining carrying value for its Houston County acreage. JETX recorded an impairment charge of $10.1 million in Selling, general and other expenses in the third quarter of 2017 related to the write-down of unproved oil and gas properties.

Substantially all of our operating businesses sell products or services that are impacted by general economic conditions in the U.S. and to a lesser extent internationally. In recent years, general economic conditions reduced the demand for products or services sold by our operating subsidiaries and/or resulted in reduced pricing for products or services. A worsening of current economic conditions could cause a decline in estimated future cash flows expected to be generated by our operations and investments. If future undiscounted cash flows are estimated to be less than the carrying amounts of the asset groups used to generate those cash flows in subsequent reporting periods, particularly for those with large investments in intangible assets, property and equipment and other long-lived assets (for example, Jefferies, National Beef, manufacturing, oil and gas production and development and certain associated company investments), impairment charges would have to be recorded.

Intangible Assets, Net and Goodwill

Intangible Assets.  Intangible assets deemed to have finite lives are generally amortized on a straight-line basis over their estimated useful lives, where the useful life is the period over which the asset is expected to contribute directly, or indirectly, to our future cash flows. Intangible assets are reviewed for impairment on an interim basis when certain events or circumstances exist. If future undiscounted cash flows are estimated to be less than the carrying amounts of the asset groups used to generate those cash flows in subsequent reporting periods, particularly for those with large investments in amortizable intangible assets, impairment charges would have to be recorded.

An intangible asset with an indefinite useful life is not amortized but assessed for impairment annually, or more frequently, when certain events or circumstances exist indicating an assessment for impairment is necessary. Impairment exists when the carrying amount exceeds its fair value. Fair value will be determined using valuation techniques consistent with what a market participant would use. All of our indefinite-lived intangible assets were recognized in connection with the Jefferies acquisition, and our annual impairment testing date for Jefferies is as of August 1.

Goodwill.  At acquisition, we allocate the cost of a business acquisition to the specific tangible and intangible assets acquired and liabilities assumed based upon their fair values. Significant judgments and estimates are often made by management to determine these values, and may include the use of appraisals, consideration of market quotes for similar transactions, use of discounted cash flow techniques or consideration of other information we believe to be relevant. Any excess of the cost of a business acquisition over the fair values of the net assets and liabilities acquired is recorded as goodwill, which is not amortized to expense. Substantially all of our goodwill was recognized in connection with the Jefferies acquisition.

At least annually, and more frequently if warranted, we will assess whether goodwill has been impaired. If the estimated fair value exceeds the carrying value, goodwill at the reporting unit level is not impaired. If the estimated fair value is less than carrying value, further analysis is necessary to determine the amount of impairment, if any, by comparing the implied fair value of the reporting unit’s goodwill to the carrying value of the reporting unit’s goodwill. The fair values will be based on widely accepted valuation techniques that we believe market participants would use, although the valuation process requires significant judgment and often involves the use of significant estimates and assumptions. The methodologies we utilize in estimating fair value include market capitalization, price-to-book multiples of comparable exchange traded companies, multiples of merger and acquisitions of similar businesses and/or projected cash flows. The estimates and assumptions used in determining fair value could have a significant effect on whether or not an impairment charge is recorded and the magnitude of such a charge. Adverse market or

F-18

economic events could result in impairment charges in future periods. Our annual goodwill impairment testing date related to Jefferies is as of August 1 and National Beef as of December 31.

Inventories and Cost of Sales

National Beef’s inventories consist primarily of beef products, beef by-products and supplies, and are stated at the lower of cost or net realizable value, with cost principally determined under the first-in-first-out method for beef products and average cost for supplies.

Manufacturing inventories are stated at the lower of cost or net realizable value, with cost principally determined under the first-in-first-out method. Manufacturing cost of sales principally includes product and manufacturing costs, inbound and outbound shipping costs and handling costs.

National Beef and manufacturing inventories are classified as Other assets in the Consolidated Statements of Financial Condition.

Payables, expense accruals and other liabilities

At December 31, 2017 and 2016, Payables, expense accruals and other liabilities include payables to brokers, dealers and clearing organizations of $2,228.9 million and $3,290.4 million, respectively, and payables to customers of securities operations of $2,664.0 million and $2,297.3 million, respectively.

Income Taxes

We record a valuation allowance to reduce our net deferred tax asset to the net amount that is more likely than not to be realized.  If in the future we determine that it is more likely than not that we will be able to realize our net deferred tax asset in excess of our net recorded amount, an adjustment to increase the net deferred tax asset would increase income in such period. If in the future we were to determine that we would not be able to realize all or part of our recorded net deferred tax asset, an adjustment to decrease the net deferred tax asset would be charged to income in such period. We are required to consider all available evidence, both positive and negative, and to weigh the evidence when determining whether a valuation allowance is required and the amount of such valuation allowance. Generally, greater weight is required to be placed on objectively verifiable evidence when making this assessment, in particular on recent historical operating results.

Our estimate of future taxable income considers all available evidence, both positive and negative, about our operating businesses and investments, includes an aggregation of individual projections for each significant operating business and investment, estimated apportionment factors for state and local taxing jurisdictions and includes all future years that we estimate we will have available net operating loss carryforwards (“NOLs”) (until 2035). We believe that our estimate of future taxable income is reasonable but inherently uncertain, and if our current or future operations and investments generate taxable income different than the projected amounts, further adjustments to the valuation allowance are possible. The current balance of the deferred tax valuation allowance principally reserves for NOLs of certain subsidiaries that are not available to offset income generated by other members of the consolidated tax return group.

We also record reserves for unrecognized tax benefits based on our assessment of the probability of successfully sustaining tax filing positions.  Interest and penalties, if any, are recorded as components of income tax expense. Management exercises significant judgment when assessing the probability of successfully sustaining tax filing positions, and in determining whether a contingent tax liability should be recorded and if so estimating the amount. If our tax filing positions are successfully challenged, payments could be required that are in excess of reserved amounts or we may be required to reduce the carrying amount of our net deferred tax asset, either of which could be significant to our Consolidated Statement of Financial Condition or results of operations.

Share-based Compensation

Share-based awards are measured based on the fair value of the award as determined in accordance with GAAP and recognized over the required service or vesting period. Certain executive share-based awards contain market, performance and service conditions. Market conditions are incorporated into the grant-date fair value using a Monte Carlo valuation model. Compensation expense for awards with market conditions is recognized over the service period and is not reversed if the market condition is not met. Awards with performance conditions are amortized over the service period if it is determined that it is probable that the performance condition will be achieved. The fair value of options and warrants are estimated at the date of grant using the Black-Scholes option pricing model. Expected forfeitures are included in determining share-based compensation expense.

F-19

Foreign Currency Translation

Assets and liabilities of foreign subsidiaries are translated to U.S. dollars using the currency exchange rates at the end of the relevant period. Revenues and expenses are translated at average exchange rates during the period. The effects of exchange rate changes on the translation of the balance sheets, net of hedging gains or losses and taxes, if any, are included in other comprehensive income (loss) in the Consolidated Statements of Comprehensive Income (Loss) and classified as Accumulated other comprehensive income in the Consolidated Statements of Financial Condition and Consolidated Statements of Changes in Equity. Gains or losses resulting from Jefferies foreign currency transactions are included in Principal transactions in the Consolidated Statements of Operations.

Earnings per Common Share

Basic earnings per share ("EPS") is computed by dividing net earnings available to common shareholders by the weighted average number of common shares outstanding and certain other shares committed to be, but not yet issued. Net earnings available to common shareholders represent net earnings to common shareholders reduced by the allocation of earnings to participating securities. Losses are not allocated to participating securities. Common shares outstanding and certain other shares committed to be, but not yet issued, include restricted stock and restricted stock units ("RSUs") for which no future service is required. Diluted EPS is computed by dividing net earnings available to common shareholders plus dividends on dilutive mandatorily redeemable convertible preferred shares and interest on convertible notes by the weighted average number of common shares outstanding and certain other shares committed to be, but not yet issued, plus all dilutive common stock equivalents outstanding during the period.

Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and, therefore, are included in the earnings allocation in computing earnings per share under the two-class method of earnings per share. Restricted stock and RSUs granted as part of share-based compensation contain nonforfeitable rights to dividends and dividend equivalents, respectively, and therefore, prior to the requisite service being rendered for the right to retain the award, restricted stock and RSUs meet the definition of a participating security. As such, we calculate basic and diluted earnings per share under the two-class method. RSUs granted under the senior executive compensation plan are not considered participating securities as the rights to dividend equivalents are forfeitable. See Note 17 for more information regarding the senior executive compensation plan.

Securitization Activities

Jefferies engages in securitization activities related to corporate loans, consumer loans, commercial mortgage loans and mortgage-backed and other asset-backed securities. Such transfers of financial assets are accounted for as sales when Jefferies has relinquished control over the transferred assets. The gain or loss on sale of such financial assets depends, in part, on the previous carrying amount of the assets involved in the transfer allocated between the assets sold and the retained interests, if any, based upon their respective fair values at the date of sale. Jefferies may retain interests in the securitized financial assets as one or more tranches of the securitization. These retained interests are included within Trading assets in the Consolidated Statements of Financial Condition at fair value. Any changes in the fair value of such retained interests are recognized within Principal transactions in the Consolidated Statements of Operations.

When a transfer of assets does not meet the criteria of a sale, the transfer is accounted for as a secured borrowing and Jefferies continues to recognize the assets of a secured borrowing, and recognize the associated financing in Other secured financings in the Consolidated Statements of Financial Condition.

Beginning in 2014, another of our subsidiaries utilized a special purpose entity to securitize automobile loans receivable. This special purpose entity is a variable interest entity and our subsidiary is the primary beneficiary; the related assets and the secured borrowings are recognized in the Consolidated Statement of Financial Condition. These secured borrowings do not have recourse to our subsidiary’s general credit.

Contingencies

In the normal course of business, we have been named, from time to time, as a defendant in legal and regulatory proceedings. We are also involved, from time to time, in other exams, investigations and similar reviews (both formal and informal) by governmental and self-regulatory agencies regarding our businesses, certain of which may result in judgments, settlements, fines, penalties or other injunctions.

We recognize a liability for a contingency when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. If the reasonable estimate of a probable loss is a range, we accrue the most likely amount of such loss, and

F-20

if such amount is not determinable, then we accrue the minimum in the range as the loss accrual. The determination of the outcome and loss estimates requires significant judgment on the part of management, can be highly subjective and is subject to significant change with the passage of time as more information becomes available. Estimating the ultimate impact of litigation matters is inherently uncertain, in particular because the ultimate outcome will rest on events and decisions of others that may not be within our power to control. We do not believe that any of our current litigation will have a significant adverse effect on our consolidated financial position, results of operations or liquidity; however, if amounts paid at the resolution of litigation are in excess of recorded reserve amounts, the excess could be significant in relation to results of operations for that period. For further information, see Note 24.

Note 3.  Accounting Developments

Accounting Developments - Adopted Accounting Standards

Share-Based Payments to Employees. In January 2017, we adopted the Financial Accounting Standards Board's ("FASB") new guidance that simplifies and improves accounting for share-based payments. The amendments include the recognition of all excess tax benefits and tax deficiencies as income tax expense or benefit in the statement of operations and changes to the timing of recognition of excess tax benefits, the accounting for forfeitures, classification of awards as either equity or liabilities and classification on the statement of cash flows. The adoption of this guidance did not have a significant impact on our consolidated financial statements. We elected to account for forfeitures as they occur, which results in dividends and dividend equivalents originally charged against retained earnings for forfeited shares to be reclassified to compensation expense in the period in which the forfeiture occurs.

Income Statement - Reporting Comprehensive Income. In February 2018, the FASB issued new guidance that allows companies the option to reclassify from accumulated other comprehensive income to retained earnings stranded tax effects resulting from the newly enacted federal corporate income tax rate. The amount of the reclassification would be the difference between the historical corporate income tax rate and the newly enacted corporate income tax rate. This will eliminate the stranded tax effects associated with the change in the federal corporate income tax rate in the Tax Act and would improve the usefulness of information reported to financial statement users. The Company uses the portfolio approach relating to the release of stranded tax effects. Under the portfolio approach, the net unrealized gains or losses recorded in accumulated other comprehensive income would be eliminated only on the date the entire portfolio of available for sale securities is sold or otherwise disposed of. The guidance is effective for annual and interim periods beginning after December 15, 2018 and early adoption is permitted. We adopted this guidance as of December 31, 2017 and elected to make the reclassification, resulting in a reclassification adjustment of $9.2 million.

F-21

Accounting Developments - Accounting Standards to be Adopted in Future Periods

Revenue Recognition.  In May 2014, the FASB issued new guidance that defines how companies report revenues from contracts with customers, and also requires enhanced disclosures. The core principle of this new guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. This guidance is effective for interim and annual periods beginning after December 15, 2017. We have adopted the new guidance as of January 1, 2018 using the modified retrospective approach with a cumulative-effect adjustment to opening retained earnings of approximately $8 million. Our implementation efforts included the identification of revenue streams within the scope of the guidance, the evaluation of certain revenue contracts and education and discussion with our consolidated subsidiaries. Based on our assessment, the impact of the adoption of the new guidance does not have a material impact on our consolidated financial statements. The below focuses on our two largest consolidated subsidiaries, whose combined revenues comprise more than 92% of our Net revenues in the Consolidated Statements of Operations for the year ended December 31, 2017.

For Jefferies, as the new revenue recognition guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, and as a result, did not have an impact on the elements of its revenues most closely associated with financial instruments, including Principal transaction revenues, Interest income and Interest expense. The new revenue standard primarily impacts the following of Jefferies revenue recognition and presentation accounting policies:

• Investment Banking Revenues. Advisory fees from mergers and acquisitions engagements are recognized at a point in time when the related transaction is completed, as the performance obligation is to successfully broker a specific transaction.

• Certain Capital Markets Revenues. Revenues associated with price stabilization activities as part of a securities underwriting were historically recognized as part of Investment banking revenues. Under the new revenue standard, revenue from these activities is recognized within Principal transaction revenues, as these revenues are not considered to be within the scope of the new standard.

• Investment Banking Advisory Expenses. Historically, expenses associated with investment banking advisory assignments were deferred until reimbursed by the client, the related fee revenue is recognized or the engagement is otherwise concluded. Under the new revenue standard, expenses are deferred only to the extent they are explicitly reimbursable by the client and the related revenue is recognized at a point in time. All other investment banking advisory related expenses, including expenses incurred related to restructuring assignments, are expensed as incurred.

• Investment Banking Underwriting and Advisory Expenses. Expenses have historically been recorded net of client reimbursements and/or netted against revenues. Under the new revenue standard, all investment banking expenses will be recognized within their respective expense category on the consolidated statements of operations and any expense reimbursements will be recognized as Investment banking revenues (i.e., expenses are no longer recorded net of client reimbursements and are not netted against revenues).

• Asset Management Fees. In certain asset management fee arrangements, Jefferies and LAM receive performance-based fees, which vary with performance or, in certain cases, are earned when the return on assets under management exceed certain benchmark returns or other performance targets. Historically, performance fees have been accrued (or reversed) quarterly based on measuring performance to date versus any relevant benchmark return hurdles stated in the investment management agreement. Under the new revenue standard, performance fees are considered variable as they are subject to fluctuation (e.g., based on market performance) and/or are contingent on a future event during the measurement period (e.g., meeting a specified benchmark rate) and are recognized only to the extent it is not probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty is resolved. Accordingly, performance fee revenue will generally be recognized only at the end of the performance period to the extent that the benchmark return has been met.

National Beef earns over 95% of its revenues through the sale of beef, pork and beef by-products. Agreements with customers for these sales typically consist of the type and quantity of products to be delivered, the unit price of each product, the estimated delivery date and credit and payment terms. The transaction price is generally fixed at this time and revenue is recognized when the customer takes control of the product. The impact of the new guidance does not materially impact how revenue is recognized for this revenue stream.

F-22

Financial Instruments. In January 2016, the FASB issued new guidance that affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. The guidance is effective for annual and interim periods beginning after December 15, 2017. We do not believe the new guidance related to equity investments and the presentation and disclosure requirements of financial instruments will have a material impact on our consolidated financial statements. We have adopted the new guidance as of January 1, 2018 with a cumulative-effect increase to opening retained earnings of approximately $28 million and a corresponding decrease to Accumulated other comprehensive income. Early adoption was permitted for the accounting guidance on financial liabilities under the fair value option and we adopted this guidance in the first quarter of 2016. The adoption of the guidance on financial liabilities under the fair value option did not have a material impact on our consolidated financial statements.

Leases. In February 2016, the FASB issued new guidance that affects the accounting and disclosure requirements for leases. The FASB requires the recognition of lease assets and lease liabilities on the statement of financial condition. The guidance is effective for annual and interim periods beginning after December 15, 2018. We are currently evaluating the impact this new guidance will have on our consolidated financial statements.

Financial Instruments - Credit Losses. In June 2016, the FASB issued new guidance for estimating credit losses on certain types of financial instruments by introducing an approach based on expected losses. The guidance is effective for annual and interim periods beginning after December 15, 2019. We are currently evaluating the impact this new guidance will have on our consolidated financial statements.

Cash Flow Classifications. In August 2016, the FASB issued new guidance to reduce the diversity in practice in how certain transactions are classified in the statement of cash flows. The guidance adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The guidance is effective for annual and interim periods beginning after December 15, 2017. In November 2016, the FASB issued new guidance on restricted cash. The guidance requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. The guidance is effective for annual and interim periods beginning after December 15, 2017. We do not believe the new guidance will have a material impact on our consolidated financial statements.

Goodwill. In January 2017, the FASB issued new guidance for simplifying goodwill impairment testing. The guidance is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted. We do not believe the new guidance will have a material impact on our consolidated financial statements.

Retirement Benefits. In March 2017, the FASB issued new guidance for improving the presentation of net periodic pension costs in the statement of operations. The update also allows the service cost to be eligible for capitalization, when applicable. The guidance is effective for annual and interim periods beginning after December 15, 2017 and early adoption is permitted. We do not believe the new guidance will have a material impact on our consolidated financial statements.

Compensation. In May 2017, the FASB issued new guidance providing clarity and reducing diversity in practice and cost and complexity when accounting for a change to the terms or conditions of a share-based payment award. The guidance is effective for annual and interim periods beginning after December 15, 2017 and early adoption is permitted. We do not believe the new guidance will have a material impact on our consolidated financial statements.

Derivatives and hedging. In August 2017, the FASB issued new guidance to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. The guidance is effective for annual and interim periods beginning after December 15, 2018 and early adoption is permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements.

F-25

The following is a description of the valuation basis, including valuation techniques and inputs, used in measuring our financial assets and liabilities that are accounted for at fair value on a recurring basis:

Corporate Equity Securities

• Exchange Traded Equity Securities:  Exchange traded equity securities are measured based on quoted closing exchange prices, which are generally obtained from external pricing services, and are categorized within Level 1 of the fair value hierarchy, otherwise they are categorized within Level 2 of the fair value hierarchy. To the extent these securities are actively traded, valuation adjustments are not applied.

• Non-Exchange Traded Equity Securities:  Non-exchange traded equity securities are measured primarily using broker quotations, pricing data from external pricing services and prices observed from recently executed market transactions and are categorized within Level 2 of the fair value hierarchy. Where such information is not available, non-exchange traded equity securities are categorized within Level 3 of the fair value hierarchy and measured using valuation techniques involving quoted prices of or market data for comparable companies, similar company ratios and multiples (e.g., price/Earnings before interest, taxes, depreciation and amortization ("EBITDA"), price/book value), discounted cash flow analyses and transaction prices observed from subsequent financing or capital issuance by Jefferies. When using pricing data of comparable companies, judgment must be applied to adjust the pricing data to account for differences between the measured security and the comparable security (e.g., issuer market capitalization, yield, dividend rate, geographical concentration).

• Equity Warrants:  Non-exchange traded equity warrants are measured primarily using pricing data from external pricing services, prices observed from recently executed market transactions and broker quotations and are categorized within Level 2 of the fair value hierarchy. Where such information is not available, non-exchange traded equity warrants are generally categorized within Level 3 of the fair value hierarchy and are measured using the Black-Scholes model with key inputs impacting the valuation including the underlying security price, implied volatility, dividend yield, interest rate curve, strike price and maturity date.

Corporate Debt Securities

• Corporate Bonds:  Corporate bonds are measured primarily using pricing data from external pricing services and broker quotations, where available, prices observed from recently executed market transactions and bond spreads or credit default swap spreads of the issuer adjusted for basis differences between the swap curve and the bond curve. Corporate bonds measured using these valuation methods are categorized within Level 2 of the fair value hierarchy. If broker quotes, pricing data or spread data is not available, alternative valuation techniques are used including cash flow models incorporating interest rate curves, single name or index credit default swap curves for comparable issuers and recovery rate assumptions. Corporate bonds measured using alternative valuation techniques are categorized within Level 3 of the fair value hierarchy and are a limited portion of our corporate bonds.

• High Yield Corporate and Convertible Bonds:  A significant portion of our high yield corporate and convertible bonds are categorized within Level 2 of the fair value hierarchy and are measured primarily using broker quotations and pricing data from external pricing services, where available, and prices observed from recently executed market transactions of Institutional size. Where pricing data is less observable, valuations are categorized within Level 3 and are based on pending transactions involving the issuer or comparable issuers, prices implied from an issuer’s subsequent financing or recapitalization, models incorporating financial ratios and projected cash flows of the issuer and market prices for comparable issuers.

Collateralized Debt Obligations and Collateralized Loan Obligations

CDOs and CLOs are measured based on prices observed from recently executed market transactions of the same or similar security or based on valuations received from third party brokers or data providers and are categorized within Level 2 or Level 3 of the fair value hierarchy depending on the observability and significance of the pricing inputs. Valuation that is based on recently executed market transactions of similar securities incorporates additional review and analysis of pricing inputs and comparability criteria, including, but not limited to, collateral type, tranche type, rating, origination year, prepayment rates, default rates, and loss severity.

U.S. Government and Federal Agency Securities

• U.S. Treasury Securities:  U.S. Treasury securities are measured based on quoted market prices and categorized within Level 1 of the fair value hierarchy.

• U.S. Agency Debt Securities:  Callable and non-callable U.S. agency debt securities are measured primarily based on quoted market prices obtained from external pricing services and are generally categorized within Level 1 or Level 2 of the fair value hierarchy.

F-26

Municipal Securities

Municipal securities are measured based on quoted prices obtained from external pricing services and are generally categorized within Level 2 of the fair value hierarchy.

Sovereign Obligations

Sovereign government obligations are measured based on quoted market prices obtained from external pricing services, where available, or recently executed independent transactions of comparable size. To the extent external price quotations are not available or recent transactions have not been observed, valuation techniques incorporating interest rate yield curves and country spreads for bonds of similar issuers, seniority and maturity are used to determine fair value of sovereign bonds or obligations. Sovereign government obligations are classified in Level 1 or Level 2 of the fair value hierarchy, primarily based on the country of issuance.

Residential Mortgage-Backed Securities

• Agency Residential Mortgage-Backed Securities:  Agency residential mortgage-backed securities include mortgage pass-through securities (fixed and adjustable rate), collateralized mortgage obligations and principal-only securities and are generally measured using market price quotations from external pricing services and categorized within Level 2 of the fair value hierarchy.

• Agency Residential Interest-Only and Inverse Interest-Only Securities ("agency Inverse IOs"):  The fair value of agency Inverse IOs is estimated using expected future cash flow techniques that incorporate prepayment models and other prepayment assumptions to amortize the underlying mortgage loan collateral. We use prices observed from recently executed transactions to develop market-clearing spread and yield curve assumptions. Valuation inputs with regard to the underlying collateral incorporate weighted average coupon, loan-to-value, credit scores, geographic location, maximum and average loan size, originator, servicer, and weighted average loan age. Agency Inverse IOs are categorized within Level 2 of the fair value hierarchy. We also use vendor data in developing our assumptions, as appropriate.

• Non-Agency Residential Mortgage-Backed Securities:  The fair value of non-agency residential mortgage-backed securities is determined primarily using discounted cash flow methodologies and securities are categorized within Level 2 or Level 3 of the fair value hierarchy based on the observability and significance of the pricing inputs used. Performance attributes of the underlying mortgage loans are evaluated to estimate pricing inputs, such as prepayment rates, default rates and the severity of credit losses. Attributes of the underlying mortgage loans that affect the pricing inputs include, but are not limited to, weighted average coupon; average and maximum loan size; loan-to-value; credit scores; documentation type; geographic location; weighted average loan age; originator; servicer; historical prepayment, default and loss severity experience of the mortgage loan pool; and delinquency rate. Yield curves used in the discounted cash flow models are based on observed market prices for comparable securities and published interest rate data to estimate market yields. In addition, broker quotes, where available, are also referenced to compare prices primarily on interest-only securities.

Commercial Mortgage-Backed Securities

• Agency Commercial Mortgage-Backed Securities:  Government National Mortgage Association (“GNMA”) project loan bonds are measured based on inputs corroborated from and benchmarked to observed prices of recent securitization transactions of similar securities with adjustments incorporating an evaluation of various factors, including prepayment speeds, default rates, and cash flow structures as well as the likelihood of pricing levels in the current market environment. Federal National Mortgage Association (“FNMA”) Delegated Underwriting and Servicing (“DUS”) mortgage-backed securities are generally measured by using prices observed for recently executed market transactions to estimate market-clearing spread levels for purposes of estimating fair value. GNMA project loan bonds and FNMA DUS mortgage-backed securities are categorized within Level 2 of the fair value hierarchy.

• Non-Agency Commercial Mortgage-Backed Securities:  Non-agency commercial mortgage-backed securities are measured using pricing data obtained from external pricing services and prices observed from recently executed market transactions and are categorized within Level 2 and Level 3 of the fair value hierarchy.

Other Asset-Backed Securities

Other asset-backed securities include, but are not limited to, securities backed by auto loans, credit card receivables, student loans and other consumer loans and are categorized within Level 2 and Level 3 of the fair value hierarchy. Valuations are primarily determined using pricing data obtained from external pricing services and broker quotes and prices observed from recently executed market transactions.

F-27

Loans and Other Receivables

• Corporate Loans:  Corporate loans categorized within Level 2 of the fair value hierarchy are measured based on market price quotations where market price quotations from external pricing services are supported by transaction data. Corporate loans categorized within Level 3 of the fair value hierarchy are measured based on price quotations that are considered to be less transparent, market prices for debt securities of the same creditor and estimates of future cash flow incorporating assumptions regarding creditor default and recovery rates and consideration of the issuer’s capital structure.

• Participation Certificates in Agency Residential Loans: Valuations of participation certificates in agency residential loans are based on observed market prices of recently executed purchases and sales of similar loans. The loan participation certificates are categorized within Level 2 of the fair value hierarchy given the observability and volume of recently executed transactions and availability of data provider pricing.

• Project Loans and Participation Certificates in GNMA Project and Construction Loans:  Valuations of participation certificates in GNMA project and construction loans are based on inputs corroborated from and benchmarked to observed prices of recent securitizations with similar underlying loan collateral to derive an implied spread. Securitization prices are adjusted to estimate the fair value of the loans incorporating an evaluation for various factors, including prepayment speeds, default rates and cash flow structures as well as the likelihood of pricing levels in the current market environment. The measurements are categorized within Level 2 of the fair value hierarchy given the observability and volume of recently executed transactions.

• Consumer Loans and Funding Facilities:  Consumer and small business whole loans and related funding facilities are valued based on observed market transactions and incorporating valuation inputs including, but not limited to, delinquency and default rates, prepayment rates, borrower characteristics, loan risk grades and loan age. These assets are categorized within Level 2 or Level 3 of the fair value hierarchy.

• Escrow and Trade Claim Receivables:  Escrow and trade claim receivables are categorized within Level 3 of the fair value hierarchy where fair value is estimated based on reference to market prices and implied yields of debt securities of the same or similar issuers. Escrow and trade claim receivables are categorized within Level 2 of the fair value hierarchy where fair value is based on recent trade activity in the same receivable.

Derivatives

• Listed Derivative Contracts:  Listed derivative contracts that are actively traded are measured based on quoted exchange prices, broker quotes or vanilla option valuations models, such as Black-Scholes, using observable valuation inputs from the principal market. Exchange quotes and/or valuation inputs are generally obtained from external vendors and pricing services. Brokers quotes are validated directly through observable and tradeable quotes. Listed derivative contracts that use unadjusted exchange close prices are generally classified within Level 1 of the fair value hierarchy. All other listed derivative contracts are generally categorized within Level 2 of the fair value hierarchy.

• Over-the-counter ("OTC") Derivative Contracts:  OTC derivative contracts are generally valued using models, whose inputs reflect assumptions that we believe market participants would use in valuing the derivative in a current transaction. Inputs to valuation models are appropriately calibrated to market data. For many OTC derivative contracts, the valuation models do not involve material subjectivity as the methodologies do not entail significant judgment and the inputs to valuation models do not involve a high degree of subjectivity as the valuation model inputs are readily observable or can be derived from actively quoted markets. OTC derivative contracts are primarily categorized within Level 2 of the fair value hierarchy given the observability and significance of the inputs to the valuation models. Where significant inputs to the valuation are unobservable, derivative instruments are categorized within Level 3 of the fair value hierarchy.

OTC options include OTC equity, foreign exchange, interest rate and commodity options measured using various valuation models, such as the Black-Scholes, with key inputs including the underlying security price, foreign exchange spot rate, commodity price, implied volatility, dividend yield, interest rate curve, strike price and maturity date. Discounted cash flow models are utilized to measure certain OTC derivative contracts including the valuations of our interest rate swaps, which incorporate observable inputs related to interest rate curves, valuations of our foreign exchange forwards and swaps, which incorporate observable inputs related to foreign currency spot rates and forward curves and valuations of our commodity swaps and forwards, which incorporate observable inputs related to commodity spot prices and forward curves. Discounted cash flow models are also utilized to measure certain variable funding note swaps, which are backed by CLOs and incorporate constant prepayment rate, constant default rate and loss severity assumptions. Credit default swaps include both index and single-name credit default swaps. External prices are available as inputs in measuring index credit default swaps and single-name credit default swaps. For commodity and equity total return swaps, market prices are generally observable for the underlying asset and used as the basis for measuring the fair value of the derivative contracts. Total return swaps executed on other underlyings are measured based on valuations received from external pricing services.

• National Beef Derivatives: National Beef uses futures contracts in order to reduce its exposure associated with entering into firm commitments to purchase live cattle at prices determined prior to the delivery of the cattle as well as firm commitments

F-28

to sell certain beef products at sales prices determined prior to shipment. The futures contracts and their related firm purchase commitments are accounted for at fair value, which are classified as Level 1 or Level 2 within the fair value hierarchy. Certain firm commitments for live cattle purchases and all firm commitments for sales are treated as normal purchases and sales and therefore not marked to market. Fair values classified as Level 1 are calculated based on the quoted market prices of identical assets or liabilities compared to National Beef's cost of those same assets or liabilities. Fair values classified as Level 2 are calculated based on the difference between the contracted price for live cattle and the relevant quoted market price for live cattle futures.

• Oil Futures Derivatives: Vitesse uses swaps and call and put options in order to reduce exposure to future oil price fluctuations. Vitesse accounts for the derivative instruments at fair value, which are classified as Level 2 within the fair value hierarchy. Fair values classified as Level 2 are determined under the income valuation technique using an option-pricing model that is based on directly or indirectly observable inputs.

Investments at Fair Value

Investments at fair value included in Trading assets on the Consolidated Statements of Financial Condition include direct equity investments in private companies, which are measured at fair value using valuation techniques involving quoted prices of or market data for comparable companies, similar company ratios and multiples (e.g., price/EBITDA, price/book value), discounted cash flow analysis and transaction prices observed for subsequent financing or capital issuance by the company. Direct equity investments in private companies are categorized within Level 2 or Level 3 of the fair value hierarchy.  Additionally, investments at fair value include investments in insurance contracts relating to Jefferies defined benefit plan in Germany. Fair value for the insurance contracts are determined using a third party and is categorized within Level 3 of the fair value hierarchy. 

Investment in FXCM

FXCM is a provider of online foreign exchange trading services. In January 2015, we entered into a credit agreement with FXCM, and provided FXCM a $300 million senior secured term loan due January 2017 (the term of which was subsequently extended to January 2019), with rights to a variable proportion of certain future distributions in connection with an FXCM sale of assets or certain other events, and to require a sale of FXCM beginning in January 2018. The loan had an initial interest rate of 10% per annum, increasing by 1.5% per annum each quarter, not to exceed 20.5% per annum. During the year ended December 31, 2017, interest accrued at 20.5% per annum. During the year ended December 31, 2017, we received $114.9 million of principal and interest from FXCM and $69.9 million of principal remained outstanding under the term loan as of December 31, 2017. Through December 31, 2017, we have received cumulatively $331.6 million of principal, interest and fees from our initial $279.0 million investment in FXCM.

Through September 1, 2016, the total amount of our investment in FXCM was reported within Trading assets, at fair value in our Consolidated Statements of Financial Condition, and unrealized and realized changes in value, including the component related to interest income on the loan, were included within Principal transactions in the Consolidated Statements of Operations. We recorded gains (losses) in Principal transactions of $23.2 million during the year ended December 31, 2017 from our term loan and $(54.6) million and $491.3 million during the years ended December 31, 2016 and 2015, respectively, from our term loan and related rights.

On September 1, 2016, we, Global Brokerage Inc. ("Global Brokerage") and Global Brokerage Holdings entered into an agreement that amended the terms of our loan and associated rights. On November 10, 2017, the terms of our loan and associated rights were amended further. Among other changes, the amendments during 2016 and 2017 extended the repayment date of the remaining loan balance to January 2019; and exchanged our rights for a 50% voting interest in FXCM and up to 75% of all distributions. Through these amendments, we also gained the right to appoint three of six board members for FXCM. We have the right, as does Global Brokerage Holdings, the owner of the remaining 50% of FXCM voting interest that is not held by Leucadia, to require a sale of FXCM beginning in January 2018. Distributions to Leucadia under the amended agreements are now: 100% until amounts due under the loan are repaid; 50% of the next $350 million; then 90% of the next $600 million; and 60% of all amounts thereafter.

Through the amendment on September 1, 2016 we gained the ability to significantly influence FXCM through our seats on the board of directors. As a result, we classify our equity investment in FXCM in our December 31, 2017 and 2016 Consolidated Statements of Financial Condition as Loans to and investments in associated companies. We account for our equity interest on a one month lag. As the amendments only extended the maturity of the term loan, we continue to use the fair value option and classify our term loan within Trading assets, at fair value.

During February 2017, Global Brokerage Holdings and FXCM's U.S. subsidiary, Forex Capital Markets LLC ("FXCM U.S.") settled complaints filed by the National Futures Association ("NFA") and the Commodity Futures Trading Commission ("CFTC")

F-29

against FXCM U.S. and certain of its principals relating to matters that occurred between 2010 and 2014. As part of the settlements, FXCM U.S. withdrew from business and sold FXCM U.S.'s customer accounts. FXCM also implemented a restructuring plan that included the termination of approximately 22% of its global workforce. The proceeds from the sale of the U.S. accounts, net of closure and severance costs, as well as regulatory capital released after the sale, has been used to pay down the Leucadia term loan.

FXCM is considered a variable interest entity ("VIE") and our term loan and equity ownership are variable interests.  We have determined that we are not the primary beneficiary of FXCM because we do not have the power to direct the activities that most significantly impact FXCM’s performance. Therefore, we do not consolidate FXCM and we account for our equity interest under the equity method as an investment in an associated company.

Our maximum exposure to loss as a result of our involvement with FXCM is limited to the carrying value of the term loan ($72.8 million) and the investment in associated company ($158.9 million), which totaled $231.7 million at December 31, 2017.

We estimate the fair value of our term loan by using a valuation model with inputs including management’s assumptions concerning the amount and timing of expected cash flows, the loan’s implied credit rating and effective yield. Because of these inputs and the degree of judgment involved, we have categorized our term loan within Level 3 of the fair value hierarchy.

Nonrecurring Fair Value Measurements

As described further in Note 10, in the first quarter of 2017 we engaged an independent valuation firm to assist management in estimating the fair value of our equity investment in FXCM. Our first quarter estimate of fair value was based on a discounted cash flow and comparable public company analysis and is categorized within Level 3 of the fair value hierarchy. The discounted cash flow valuation model used inputs including management's projections of future FXCM cash flows and a discount rate of approximately 15%. The comparable public company model used market data for comparable companies including a price to EBITDA multiple of 5.4 and a price to revenue multiple of 1.5. The estimated fair value of our equity investment in FXCM was $186.7 million, which was $130.2 million lower than the carrying value at the end of the first quarter 2017. As a result, an impairment charge of $130.2 million was recorded in Income (loss) related to associated companies in the first quarter of 2017.

In 2015, we recorded impairment charges in Selling, general and other expenses of $27.7 million, primarily related to a $20.3 million impairment at JETX and an impairment charge related to National Beef's Brawley plant (which was closed in 2014) of $4.7 million. JETX owns both proved and unproved oil and gas properties that are included in Other assets in our Consolidated Statements of Financial Condition. For the oil and gas impairment test related to proved properties, we compare expected undiscounted future net cash flows to the unamortized capitalized cost of the asset. If the future undiscounted net cash flows are lower than the unamortized capital cost, we reduce the capitalized cost to fair market value. We used a third party reserve report in which the cash flows were calculated using West Texas Intermediate (oil) and Henry Hub (gas) NYMEX futures prices as of December 31, 2015. For one of our oil fields, the undiscounted net cash flows were lower than the unamortized capital cost and as a result, we wrote off the total capital cost.

In the third quarter of 2016, JETX curtailed development of both its southern acreage in the East Eagle Ford and its Houston County acreage and performed an impairment analysis of these unproved oil and gas properties. To measure the estimated fair value of the unproved properties, we used unobservable Level 3 inputs, which took into account the following factors: remaining lease terms, drilling results and/or future plans to develop the acreage. The estimated fair value of JETX's southern acreage in the East Eagle Ford and its Houston County acreage totaled $51.6 million, which was $55.0 million lower than the carrying value as of the end of third quarter of 2016. As a result, an impairment charge of $55.0 million was recorded in Selling, general and other expenses in the third quarter of 2016.

In the third quarter of 2017, JETX decided to focus on its other higher returning acreage and as a result JETX wrote off the remaining carrying value for its Houston County acreage. JETX recorded an impairment charge of $10.1 million in Selling, general and other expenses in the third quarter of 2017 related to the write-down of unproved oil and gas properties.

Investments at Fair Value Based on NAV and Investments in Managed Funds

Investments at fair value based on NAV and Investments in managed funds include investments in hedge funds, fund of funds, private equity funds and other funds, which are measured at the NAV of the funds provided by the fund managers and are excluded from the fair value hierarchy.

(1) Where fair value is calculated based on NAV, fair value has been derived from each of the funds' capital statements.

(2) This category includes investments in hedge funds that invest, long and short, in primarily equity securities in domestic and international markets in both the public and private sectors. At December 31, 2017 and 2016, 73% and 83%, respectively, of these investments are redeemable with 10 business days or less prior written notice, and 15% and 17%, respectively, are redeemable with 30 to 60 days prior written notice.

(3) This category includes investments in funds that invest in loans secured by a first trust deed on property, domestic and international public high yield debt, private high yield investments, senior bank loans, public leveraged equities, distressed debt and private equity investments. There are no redemption provisions. 

(4) This category includes investments in fund of funds that invest in various private equity funds. The investments in this category are managed by us and have no redemption provisions. These investments are gradually being liquidated or we have requested redemption, however, we are unable to estimate when these funds will be received.

(5) The investments in this category include investments in equity funds that invest in the equity of various U.S. and foreign private companies in the energy, technology, internet service and telecommunication service industries. These investments cannot be redeemed; instead distributions are received through the liquidation of the underlying assets of the funds, which are expected to liquidate in one to six years. 

(6) This category includes investments in hedge funds that invest, long and short, primarily in multi-asset securities in domestic and international markets in both the public and private sectors. At both December 31, 2017 and 2016, investments representing approximately 12% of the fair value of investments in this category are redeemable with 30 days prior written notice.

Other Secured Financings

Other secured financings that are accounted for at fair value include notes issued by consolidated VIEs, which are classified as Level 2 or Level 3 within the fair value hierarchy.  Fair value is based on recent transaction prices for similar assets. 

Short-term Borrowings and Long-term Debt

Short-term borrowings that are accounted for at fair value include equity-linked notes, which are generally categorized as Level 2 within the fair value hierarchy, as the fair value is based on the price of the underlying equity security. Long-term debt includes variable rate, fixed-to-floating rate, CMS (constant maturity swap) and Bermudan structured notes. These are valued using various valuation models that incorporate Jefferies own credit spread, market price quotations from external pricing sources referencing the appropriate interest rate curves, volatilities and other inputs and are generally categorized within Level 2 of the fair value hierarchy. In addition, pricing transparency has been evidenced based on transaction data from recently issued notes.

Analysis of Level 3 Assets and Liabilities for the year ended December 31, 2017

During the year ended December 31, 2017, transfers of assets of $38.2 million from Level 2 to Level 3 of the fair value hierarchy are attributed to:

• Residential mortgage-backed securities of $19.6 million and corporate debt securities of $8.3 million due to a lack of observable market transactions.

During the year ended December 31, 2017, transfers of assets of $54.9 million from Level 3 to Level 2 are attributed to:

• Loans and other receivables of $40.9 million due to greater pricing transparency supporting classification into Level 2;

Net gains on Level 3 assets were $5.9 million and net gains on Level 3 liabilities were $1.7 million for the year ended December 31, 2017. Net gains on Level 3 assets were primarily due to increased valuations of our investment in FXCM, investments at fair value and certain loans and other receivables partially offset by decreased valuations of CDOs and CLOs, other asset-backed securities and residential mortgage-backed securities. Net gains on Level 3 liabilities were primarily due to increased valuations of certain net derivatives.

During the year ended December 31, 2015, there were transfers of other secured financings of $51.6 million from Level 3 to Level 2 due to an increase in observable inputs in the valuation.

Net gains on Level 3 assets were $455.5 million and net gains on Level 3 liabilities were $7.6 million for the year ended December 31, 2015. Net gains on Level 3 assets were primarily due to increased valuations of our investment in FXCM and increase in valuation of certain investments at fair value and corporate equity securities partially offset by decreased valuations of CDOs and CLOs, certain loans and other receivables and residential and commercial mortgage-backed securities. Net gains on Level 3 liabilities were primarily due to increased valuations of certain net derivatives.

Quantitative Information about Significant Unobservable Inputs used in Level 3 Fair Value Measurements

The tables below present information on the valuation techniques, significant unobservable inputs and their ranges for our financial assets and liabilities, subject to threshold levels related to the market value of the positions held, measured at fair value on a recurring basis with a significant Level 3 balance. The range of unobservable inputs could differ significantly across different firms given the range of products across different firms in the financial services sector. The inputs are not representative of the inputs that could have been used in the valuation of any one financial instrument (i.e., the input used for valuing one financial instrument within a particular class of financial instruments may not be appropriate for valuing other financial instruments within that given class). Additionally, the ranges of inputs presented below should not be construed to represent uncertainty regarding the fair values of our financial instruments; rather the range of inputs is reflective of the differences in the underlying characteristics of the financial instruments in each category.

For certain categories, we have provided a weighted average of the inputs allocated based on the fair values of the financial instruments comprising the category. We do not believe that the range or weighted average of the inputs is indicative of the reasonableness of uncertainty of our Level 3 fair values. The range and weighted average are driven by the individual financial instruments within each category and their relative distribution in the population. The disclosed inputs when compared with the inputs as disclosed in other periods should not be expected to necessarily be indicative of changes in our estimates of unobservable inputs for a particular financial instrument as the population of financial instruments comprising the category will vary from period to period based on purchases and sales of financial instruments during the period as well as transfers into and out of Level 3 each period.

The fair values of certain Level 3 assets and liabilities that were determined based on third-party pricing information, unadjusted past transaction prices, reported net asset value or a percentage of the reported enterprise fair value are excluded from the above tables. At December 31, 2017 and 2016, asset exclusions consisted of $228.6 million and $325.0 million, respectively, primarily comprised of investments at fair value, private equity securities, CDOs and CLOs, municipal securities, non-exchange traded securities and loans and other receivables. At December 31, 2017 and 2016, liability exclusions consisted of $4.2 million and $1.6 million, respectively, of other secured financings, commercial mortgage-backed securities, loans and corporate debt and equity securities.

Sensitivity of Fair Values to Changes in Significant Unobservable Inputs

For recurring fair value measurements categorized within Level 3 of the fair value hierarchy, the sensitivity of the fair value measurement to changes in significant unobservable inputs and interrelationships between those unobservable inputs (if any) are described below:

• Non-exchange traded securities and equity swaps using comparable pricing valuation techniques. A significant increase (decrease) in the comparable asset and underlying stock price in isolation would result in a significantly higher (lower) fair value measurement.

• Corporate debt securities using a convertible bond model. A significant increase (decrease) in the bond discount rate/yield would result in a significantly lower (higher) fair value measurement. A significant increase (decrease) in volatility would result in a significantly higher (lower) fair value measurement.

• Non-exchange traded securities, corporate debt securities, loans and other receivables, unfunded commitments, credit default swaps, interest rate swaps, total return swaps, other asset-backed securities and private equity securities using a market approach valuation technique. A significant increase (decrease) in the EBITDA or other multiples in isolation would result in a significantly higher (lower) fair value measurement. A significant increase (decrease) in the discount rate/yield of a loan and other receivable or certain derivatives would result in a significantly lower (higher) fair value measurement. A significant increase (decrease) in the transaction level of a private equity security, corporate debt security or loan and other receivable would result in a significantly higher (lower) fair value measurement. A significant increase (decrease) in the underlying stock price of the non-exchange traded securities would result in a significantly higher (lower) fair value measurement. A significant increase (decrease) in the credit spread of certain derivatives would result in a significantly lower (higher) fair value measurement. A significant increase (decrease) in the price of the private equity securities, non-exchange traded securities, corporate debt securities, unfunded commitments, total return swaps, other asset-backed securities or loans and other receivables would result in a significantly higher (lower) fair value measurement. A significant increase (decrease) in the estimated recovery rates of the cash flow outcomes underlying the corporate debt securities and loans and other receivables would result in a significantly higher (lower) fair value measurement.

• Loans and other receivables, CDOs and CLOs, commercial mortgage-backed securities and other asset-backed securities using scenario analysis. A significant increase (decrease) in the possible recovery rates of the cash flow outcomes underlying the investment would result in a significantly higher (lower) fair value measurement for the financial instrument. A significant increase (decrease) in the price of the commercial mortgage-backed securities would result in a significantly higher (lower) fair value measurement.

• CDOs and CLOs, residential and commercial mortgage-backed securities, other asset-backed securities and variable funding notes using a discounted cash flow valuation technique. A significant increase (decrease) in isolation in the constant default rate, loss severity or cumulative loss rate would result in a significantly lower (higher) fair value measurement. The impact of changes in the constant prepayment rate and duration would have differing impacts depending on the capital structure and type of security. A significant increase (decrease) in the discount rate/security yield would result in a significantly lower (higher) fair value measurement.

• Derivative equity options using an option model. A significant increase (decrease) in volatility would result in a significantly higher (lower) fair value measurement.

• Derivative equity options using a default rate model. A significant increase (decrease) in default probability would result in a significantly lower (higher) fair value measurement.

• Non-exchange traded securities and loans and other receivables using a present value model. A significant increase (decrease) in average silver production would result in a significantly higher (lower) fair value measurement.

• FXCM term loan using a discounted cash flow valuation technique. A significant increase (decrease) in term based on the time to pay off the loan would result in a higher (lower) fair value measurement. 

Fair Value Option Election

We have elected the fair value option for all loans and loan commitments made by Jefferies capital markets businesses. These loans and loan commitments include loans entered into by Jefferies Investment Banking division in connection with client bridge financing and loan syndications, loans purchased by Jefferies leveraged credit trading desk as part of its bank loan trading activities

F-38

and mortgage and consumer loan commitments, purchases and fundings in connection with mortgage-and other asset-backed securitization activities. Loans and loan commitments originated or purchased by Jefferies leveraged credit and mortgage-backed businesses are managed on a fair value basis. Loans are included in Trading assets and loan commitments are included in Trading liabilities. The fair value option election is not applied to loans made to affiliate entities as such loans are entered into as part of ongoing, strategic business ventures. Loans to affiliate entities are included in Loans to and investments in associated companies in the Consolidated Statements of Financial Condition and are accounted for on an amortized cost basis. Jefferies has also elected the fair value option for certain of its structured notes which are managed by Jefferies capital markets business and are included in Long-term debt and Short-term borrowings in the Consolidated Statements of Financial Condition. Jefferies has elected the fair value option for certain financial instruments held by its subsidiaries as the investments are risk managed on a fair value basis. The fair value option has also been elected for certain secured financings that arise in connection with Jefferies securitization activities and other structured financings. Other secured financings, receivables from brokers, dealers and clearing organizations, receivables from customers of securities operations, payables to brokers, dealers and clearing organizations and payables to customers of securities operations, are accounted for at cost plus accrued interest rather than at fair value; however, the recorded amounts approximate fair value due to their liquid or short-term nature.

The following is a summary of Jefferies gains (losses) due to changes in instrument specific credit risk on loans, other receivables and debt instruments and gains (losses) due to other changes in fair value on long-term debt and short-term borrowings measured at fair value under the fair value option for the years ended December 31, 2017, 2016 and 2015 (in thousands):

The following is a summary of the amount by which contractual principal exceeds fair value for loans and other receivables and long-term debt measured at fair value under the fair value option (in thousands):

	December 31, 2017		December 31, 2016
Financial instruments owned:
Loans and other receivables (1)	$	752,076	$	1,325,938
Loans and other receivables on nonaccrual status and/or greater than 90 days past due (1) (2)	$	159,462	$	205,746
Long-term debt	$	32,839	$	20,202

(1) Interest income is recognized separately from other changes in fair value and is included within Interest income in the Consolidated Statements of Operations.

(2) Amounts include all loans and other receivables greater than 90 or more days past due by which contractual principal exceeds fair value of $38.7 million and $64.6 million at December 31, 2017 and 2016, respectively.

F-39

The aggregate fair value of Jefferies loans and other receivables on nonaccrual status and/or greater than 90 days or more past due, was $55.1 million and $29.8 million at December 31, 2017 and 2016, respectively, which includes loans and other receivables greater than 90 days past due of $37.4 million and $18.9 million at December 31, 2017 and 2016, respectively.

Jefferies had elected the fair value option for its investment in KCG Holdings, Inc. ("KCG"). The change in the fair value of this investment was $93.4 million, $19.6 million and $49.1 million for 2017, 2016 and 2015, respectively. Jefferies investment in KCG was sold in July 2017. Additionally, in connection with a KCG shares and warrants exchange transaction, Jefferies earned advisory fees of $2.9 million during the year ended December 31, 2016. Jefferies has also separately entered into securities lending transactions with KCG in the normal course of its capital markets activities. The balances of Securities borrowed and Securities loaned were $9.2 million and $9.2 million, respectively, December 31, 2016.

As of December 31, 2017 and 2016, we owned approximately 46.6 million common shares of HRG, representing approximately 23% of HRG’s outstanding common shares, which are accounted for under the fair value option. The shares are included in our Consolidated Statements of Financial Condition at fair value of $789.9 million and $725.1 million at December 31, 2017 and 2016, respectively.  The shares were acquired at an aggregate cost of $475.6 million. The change in the fair value of our investment in HRG was $64.8 million, $93.2 million and $(28.0) millionduring the years ended December 31, 2017, 2016 and 2015, respectively. As reported in its Form 10-K for its fiscal years ended September 30, 2017, 2016 and 2015, HRG's revenues were $5,008.5 million, $5,048.6 million and $4,753.8 million, respectively; net income (loss) from continuing operations was $102.9 million, $144.2 million and $(219.7) million, respectively; net income (loss) was $273.2 million, $(33.9) million and $(512.4) million, respectively; and net income (loss) attributable to HRG was $106.0 million, $(198.8) million and $(556.8) million, respectively. We currently have two directors on HRG’s board, including our Chairman who serves as HRG's Chairman and CEO. 

We believe accounting for these investments at fair value better reflects the economics of these investments, and quoted market prices for these investments provides an objectively determined fair value at each balance sheet date. Our investment in HomeFed, which is a publicly traded company, is accounted for under the equity method of accounting rather than the fair value option method. HomeFed’s common stock is not listed on any stock exchange, and price information for the common stock is not regularly quoted on any automated quotation system. It is traded in the over-the-counter market with high and low bid prices published by the NASD OTC Bulletin Board Service; however, trading volume is minimal. For these reasons, we did not elect the fair value option for HomeFed.

Financial Instruments Not Measured at Fair Value

Certain of our financial instruments are not carried at fair value but are recorded at amounts that approximate fair value due to their liquid or short-term nature and generally negligible credit risk. These financial assets include Cash and cash equivalents and Cash and securities segregated and on deposit for regulatory purposes or deposited with clearing and depository organizations and would generally be presented in Level 1 of the fair value hierarchy. Cash and securities segregated and on deposit for regulatory purposes or deposited with clearing and depository organizations includes U.S. Treasury securities with a fair value of $99.7 million and $99.9 million at December 31, 2017 and 2016, respectively. See Note 26 for additional information related to financial instruments not measured at fair value.

Note 5.  Derivative Financial Instruments

Off-Balance Sheet Risk

Jefferies has contractual commitments arising in the ordinary course of business for securities loaned or purchased under agreements to resell, repurchase agreements, future purchases and sales of foreign currencies, securities transactions on a when-issued basis and underwriting. Each of these financial instruments and activities contains varying degrees of off-balance sheet risk whereby the fair values of the securities underlying the financial instruments may be in excess of, or less than, the contract amount. The settlement of these transactions is not expected to have a material effect upon our consolidated financial statements.

Derivative Financial Instruments

Derivative activities are recorded at fair value in the Consolidated Statements of Financial Condition in Trading assets and Trading liabilities, net of cash paid or received under credit support agreements and on a net counterparty basis when a legally enforceable right to offset exists under a master netting agreement. Predominantly, Jefferies and our Leucadia Asset Management businesses may enter into derivative transactions to satisfy the needs of its clients and to manage its own exposure to market and credit risks resulting from trading activities. In addition, Jefferies applies hedge accounting to an interest rate swap that has been designated

F-40

as a fair value hedge of the changes in fair value due to the benchmark interest rate for certain fixed rate senior long-term debt. See Notes 4 and 24 for additional disclosures about derivative financial instruments.

Derivatives are subject to various risks similar to other financial instruments, including market, credit and operational risk. The risks of derivatives should not be viewed in isolation, but rather should be considered on an aggregate basis along with our other trading-related activities. Jefferies manages the risks associated with derivatives on an aggregate basis along with the risks associated with proprietary trading as part of its firm wide risk management policies.

In connection with Jefferies derivative activities, Jefferies may enter into International Swaps and Derivative Association, Inc. (“ISDA”) master netting agreements or similar agreements with counterparties. See Note 11 for additional information with respect to financial statement offsetting.

The following tables present the fair value and related number of derivative contracts categorized by type of derivative contract as reflected in the Consolidated Statements of Financial Condition at December 31, 2017 and 2016. The fair value of assets/liabilities represents our receivable/payable for derivative financial instruments, gross of counterparty netting and cash collateral received and pledged. The following tables also provide information regarding: 1) the extent to which, under enforceable master netting arrangements, such balances are presented net in our Consolidated Statements of Financial Condition as appropriate under GAAP and 2) the extent to which other rights of setoff associated with these arrangements exist and could have an effect on our financial position (in thousands, except contract amounts):

Credit Related Derivative Contracts

The external credit ratings of the underlyings or referenced assets for our written credit related derivative contracts (in millions):

	External Credit Rating
	Investment Grade		Non-investment Grade		Total Notional

Single name credit default swaps	122.4		261.2		$	383.6

Contingent Features

Certain of Jefferies derivative instruments contain provisions that require their debt to maintain an investment grade credit rating from each of the major credit rating agencies. If Jefferies debt were to fall below investment grade, it would be in violation of these provisions and the counterparties to the derivative instruments could request immediate payment or demand immediate and ongoing full overnight collateralization on Jefferies derivative instruments in liability positions. The aggregate fair value of all derivative instruments with such credit-risk-related contingent features that are in a liability position at December 31, 2017 and 2016 is $95.1 million and $70.6 million, respectively, for which Jefferies has posted collateral of $80.8 million and $44.4 million, respectively, in the normal course of business. If the credit-risk-related contingent features underlying these agreements were triggered on December 31, 2017 and 2016, Jefferies would have been required to post an additional $14.3 million and $26.1 million, respectively, of collateral to its counterparties.

Other Derivatives

National Beef uses futures contracts in order to reduce its exposure associated with entering into firm commitments to purchase live cattle at prices determined prior to the delivery of the cattle as well as firm commitments to sell certain beef products at sales prices determined prior to shipment. National Beef accounts for the futures contracts at fair value. Firm commitments for sales are treated as normal sales and therefore not marked to market. Certain firm commitments to purchase cattle, are marked to market when a price has been agreed upon, otherwise they are treated as normal purchases and, therefore, not marked to market. The gains and losses associated with the change in fair value of the futures contracts and offsetting gains and losses associated with changes in the market value of certain of the firm purchase commitments are recorded to Beef processing services revenue and Cost of sales in the period of change.

Vitesse uses swaps and call and put options in order to reduce exposure to future oil price fluctuations. Vitesse accounts for the derivative instruments at fair value. The gains and losses associated with the change in fair value of the derivatives are recorded in Other revenues.

Note 6.  Collateralized Transactions

Jefferies enters into secured borrowing and lending arrangements to obtain collateral necessary to effect settlement, finance inventory positions, meet customer needs or re-lend as part of dealer operations. Jefferies monitors the fair value of the securities loaned and borrowed on a daily basis as compared with the related payable or receivable, and requests additional collateral or returns excess collateral, as appropriate. Jefferies pledges financial instruments as collateral under repurchase agreements, securities lending agreements and other secured arrangements, including clearing arrangements. Jefferies agreements with counterparties generally contain contractual provisions allowing the counterparty the right to sell or repledge the collateral. Pledged securities owned that can be sold or repledged by the counterparty are included in Financial instruments owned and noted parenthetically as Securities pledged on our Consolidated Statements of Financial Condition.

Jefferies receives securities as collateral under resale agreements, securities borrowing transactions and customer margin loans.  Jefferies also receives securities as collateral in connection with securities-for-securities transactions in which it is the lender of securities. In many instances, Jefferies is permitted by contract to rehypothecate the securities received as collateral. These securities may be used to secure repurchase agreements, enter into securities lending transactions, satisfy margin requirements on derivative transactions or cover short positions. At December 31, 2017 and 2016, the approximate fair value of securities received as collateral by Jefferies that may be sold or repledged was $27.1 billion and $25.5 billion, respectively. A substantial portion of these securities have been sold or repledged.

F-45

Note 7.  Securitization Activities

Jefferies engages in securitization activities related to corporate loans, commercial mortgage loans, consumer loans and mortgage-backed and other asset-backed securities. In securitization transactions, Jefferies transfers assets to special purpose entities ("SPEs") and acts as the placement or structuring agent for the beneficial interests sold to investors by the SPE. A significant portion of the securitization transactions are securitization of assets issued or guaranteed by U.S. government agencies. These SPEs generally meet the criteria of VIEs; however, the SPEs are generally not consolidated as Jefferies is not considered the primary beneficiary for these SPEs. 

Jefferies accounts for securitization transactions as sales provided it has relinquished control over the transferred assets. Transferred assets are carried at fair value with unrealized gains and losses reflected in Principal transactions revenues in the Consolidated Statements of Operations prior to the identification and isolation for securitization. Subsequently, revenues recognized upon securitization are reflected as net underwriting revenues. Jefferies generally receives cash proceeds in connection with the transfer of assets to an SPE. Jefferies may, however, have continuing involvement with the transferred assets, which is limited to retaining one or more tranches of the securitization (primarily senior and subordinated debt securities in the form of mortgage- and other asset-backed securities or CLOs), which are included in Trading assets and are generally initially categorized as Level 2 within the fair value hierarchy. Jefferies applies fair value accounting to the securities. 

The following table presents activity related to Jefferies securitizations that were accounted for as sales in which it had continuing involvement during the years ended December 31, 2017, 2016 and 2015 (in millions):

	2017		2016		2015
Transferred assets	$	4,552.9	$	5,786.0	$	5,770.5
Proceeds on new securitizations	4,594.5		5,809.0		5,811.3
Cash flows received on retained interests	28.7		28.2		31.2

Jefferies has no explicit or implicit arrangements to provide additional financial support to these SPEs, has no liabilities related to these SPEs and has no outstanding derivative contracts executed in connection with these securitizations at December 31, 2017 and 2016.

The following table summarizes Jefferies retained interests in SPEs where it transferred assets and has continuing involvement and received sale accounting treatment (in millions):

	December 31, 2017				December 31, 2016
Securitization Type	Total Assets		Retained Interests		Total Assets		Retained Interests
U.S. government agency residential mortgage-backed securities	$	6,383.5	$	28.2	$	7,584.9	$	31.0
U.S. government agency commercial mortgage-backed securities	2,075.7		81.4		1,806.3		29.6
CLOs	3,957.8		20.3		4,102.2		37.0
Consumer and other loans	247.6		47.8		395.7		25.3

Total assets represent the unpaid principal amount of assets in the SPEs in which Jefferies has continuing involvement and are presented solely to provide information regarding the size of the transactions and the size of the underlying assets supporting its retained interests, and are not considered representative of the risk of potential loss. Assets retained in connection with a securitization transaction represent the fair value of the securities of one or more tranches issued by an SPE, including senior and subordinated tranches. Jefferies risk of loss is limited to this fair value amount which is included in total Trading assets in our Consolidated Statements of Financial Condition.

Although not obligated, in connection with secondary market-making activities Jefferies may make a market in the securities issued by these SPEs. In these market-making transactions, Jefferies buys these securities from and sells these securities to investors.  Securities purchased through these market-making activities are not considered to be continuing involvement in these SPEs. To the extent Jefferies purchased securities through these market-making activities and Jefferies is not deemed to be the primary beneficiary of the VIE, these securities are included in agency and non-agency mortgage- and asset-backed securitizations in the nonconsolidated VIEs section presented in Note 9.

F-46

Foursight Capital also utilized SPEs to securitize automobile loans receivable. These SPEs are VIEs and our subsidiary is the primary beneficiary; the related assets and the secured borrowings are recognized in the Consolidated Statements of Financial Condition. These secured borrowings do not have recourse to our subsidiary’s general credit. See Note 9 for further information on securitization activities and VIEs.

Note 9.  Variable Interest Entities

VIEs are entities in which equity investors lack the characteristics of a controlling financial interest. VIEs are consolidated by the primary beneficiary. The primary beneficiary is the party who has both the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and an obligation to absorb losses of the entity or a right to receive benefits from the entity that could potentially be significant to the entity.

Our variable interests in VIEs include debt and equity interests, equity interests in associated companies, commitments, guarantees and certain fees. Our involvement with VIEs arises primarily from the following activities, but also includes other activities discussed below:

• Purchases of securities in connection with our trading and secondary market-making activities;

• Retained interests held as a result of securitization activities, including the resecuritization of mortgage- and other asset-backed securities and the securitization of commercial mortgage, corporate and consumer loans;

• Acting as placement agent and/or underwriter in connection with client-sponsored securitizations;

• Financing of agency and non-agency mortgage- and other asset-backed securities;

• Real estate investments;

• Warehouse funding arrangements for client-sponsored consumer loan vehicles and CLOs through participation certificates and revolving loan and note commitments; and

• Loans to, investments in and fees from various investment vehicles.

We determine whether we are the primary beneficiary of a VIE upon our initial involvement with the VIE and we reassess whether we are the primary beneficiary of a VIE on an ongoing basis. Our determination of whether we are the primary beneficiary of a VIE is based upon the facts and circumstances for each VIE and requires significant judgment. Our considerations in determining the VIE’s most significant activities and whether we have power to direct those activities include, but are not limited to, the VIE’s purpose and design and the risks passed through to investors, the voting interests of the VIE, management, service and/or other agreements of the VIE, involvement in the VIE’s initial design and the existence of explicit or implicit financial guarantees. In situations where we have determined that the power over the VIE’s significant activities is shared, we assess whether we are the party with the power over the most significant activities. If we are the party with the power over the most significant activities, we meet the "power" criteria of the primary beneficiary. If we do not have the power over the most significant activities or we determine that decisions require consent of each sharing party, we do not meet the "power" criteria of the primary beneficiary.

We assess our variable interests in a VIE both individually and in aggregate to determine whether we have an obligation to absorb losses of or a right to receive benefits from the VIE that could potentially be significant to the VIE. The determination of whether our variable interest is significant to the VIE requires significant judgment. In determining the significance of our variable interest, we consider the terms, characteristics and size of the variable interests, the design and characteristics of the VIE, our involvement in the VIE and our market-making activities related to the variable interests.

Consolidated VIEs

The following table presents information about the assets and liabilities of our consolidated VIEs, which are presented in our Consolidated Statements of Financial Condition in the respective asset and liability categories (in millions). The assets and liabilities in the table below are presented prior to consolidation and thus a portion of these assets and liabilities are eliminated in consolidation.

	December 31, 2017		December 31, 2016
	Securitization Vehicles		Securitization Vehicles		Real Estate Investment Vehicles
Cash	$	11.7	$	18.4	$	2.2

(1) Securities purchased under agreements to resell represent an amount due under a collateralized transaction on a related consolidated entity, which is eliminated in consolidation.

(2) Approximately $44.1 million and $57.6 million of the secured financing represents an amount held by Jefferies in inventory and eliminated in consolidation at December 31, 2017 and 2016, respectively.

(3) Includes $32.0 million and $20.0 million at December 31, 2017 and 2016, respectively, of intercompany payables that are eliminated in consolidation.

Securitization Vehicles.  Jefferies is the primary beneficiary of mortgage-backed financing vehicles to which Jefferies sells agency and non-agency residential and commercial mortgage loans and mortgage-backed securities pursuant to the terms of a master repurchase agreement. Jefferies manages the assets within these vehicles. Jefferies variable interests in these vehicles consist of its collateral margin maintenance obligations under the master repurchase agreement and retained interests in securities issued. The assets of these VIEs consist of reverse repurchase agreements, which are available for the benefit of the vehicle’s debt holders. The creditors of these VIEs do not have recourse to Jefferies general credit and each such VIE’s assets are not available to satisfy any other debt.

Jefferies is also the primary beneficiary of securitization vehicles associated with their financing of consumer and small business loans. In the creation of the securitization vehicles, Jefferies was involved in the decisions made during the establishment and design of the entities and holds variable interests consisting of the securities retained that could potentially be significant. The assets of the VIEs consist of the small business loans and term loans backed by consumer installment receivables, which are available for the benefit of the vehicles' beneficial interest holders. The creditors of the VIEs do not have recourse to Jefferies general credit and the assets of the VIEs are not available to satisfy any other debt.

At December 31, 2017 and 2016, Foursight Capital is the primary beneficiary of SPEs it utilized to securitize automobile loans receivable. Foursight Capital acts as the servicer for which it receives a fee, and owns an equity interest in the SPEs. The notes issued by the SPEs are secured solely by the assets of the SPEs and do not have recourse to Foursight Capital’s general credit and the assets of the VIEs are not available to satisfy any other debt. During the year ended December 31, 2017, a pool of automobile loan receivables aggregating $186.5 million was securitized by Foursight Capital in connection with a secured borrowing offering. The majority of the proceeds from issuance of the secured borrowing were used to pay down Foursight Capital’s two credit facilities.

F-49

Real Estate Investment Vehicles. At December 31, 2016, 54 Madison, which we consolidated as a result of our control of the 54 Madison investment committee, had real estate investments in which it is the primary beneficiary. 54 Madison was involved in the decisions made during the establishment and design of the investment entities. 54 Madison's variable interests consisted of its investment in and management of the assets within these entities. The assets of these VIEs consisted primarily of financing note receivables and investments in associated companies, which were available for the benefit of the VIEs' debt holders. The debt holders of these VIEs had recourse to 54 Madison's general credit and the assets of the VIEs were not available to satisfy any other debt. As a result of the sale of our interest in the general partnership during 2017, 54 Madison has been deconsolidated and is reflected in Loans to and investments in associated companies at December 31, 2017.

Nonconsolidated VIEs

The following tables present information about our variable interests in nonconsolidated VIEs (in millions):

	Financial Statement Carrying Amount				Maximum Exposure to Loss		VIE Assets
	Assets		Liabilities
December 31, 2017
CLOs	$	168.1	$	8.9	$	1,030.4	$	5,364.3
Consumer loan vehicles	254.8		—		759.8		2,322.7
Related party private equity vehicles	23.7		—		45.4		75.0
Other private investment vehicles	133.0		—		142.0		4,624.9
Total	$	579.6	$	8.9	$	1,977.6	$	12,386.9
December 31, 2016
CLOs	$	264.7	$	4.8	$	930.0	$	4,472.9
Consumer loan vehicles	90.3		—		219.6		985.5
Related party private equity vehicles	37.6		—		63.6		155.6
Real estate investment vehicles	90.3		—		101.8		85.6
Other private investment vehicles	84.0		—		95.8		4,529.7
Total	$	566.9	$	4.8	$	1,410.8	$	10,229.3

Our maximum exposure to loss often differs from the carrying value of the variable interests. The maximum exposure to loss is dependent on the nature of the variable interests in the VIEs and is limited to the notional amounts of certain loan and equity commitments and guarantees. Our maximum exposure to loss does not include the offsetting benefit of any financial instruments that may be utilized to hedge the risks associated with its variable interests and is not reduced by the amount of collateral held as part of a transaction with a VIE.

Collateralized Loan Obligations.  Assets collateralizing the CLOs include bank loans, participation interests and sub-investment grade and senior secured U.S. loans. Jefferies underwrites securities issued in CLO transactions on behalf of sponsors and provides advisory services to the sponsors. Jefferies may also sell corporate loans to the CLOs. Jefferies variable interests in connection with CLOs where it has been involved in providing underwriting and/or advisory services consist of the following:

• Forward sale agreements whereby Jefferies commits to sell, at a fixed price, corporate loans and ownership interests in an entity holding such corporate loans to CLOs;

• Warehouse funding arrangements in the form of participation interests in corporate loans held by CLOs and commitments to fund such participation interests;

• Trading positions in securities issued in a CLO transaction;

• Investments in variable funding notes issued by CLOs; and

• A guarantee to a CLO managed by Jefferies Finance, whereby Jefferies guarantees certain of the obligations of Jefferies Finance to the CLO.

Consumer Loan Vehicles. Jefferies provides financing and lending related services to certain client-sponsored VIEs in the form of revolving funding note agreements, revolving credit facilities and forward purchase agreements. The underlying assets, which are collateralizing the vehicles, are primarily composed of unsecured consumer and small business loans. In addition, Jefferies may provide structuring and advisory services and act as an underwriter or placement agent for securities issued by the vehicles.  Jefferies does not control the activities of these entities.

F-50

Related Party Private Equity Vehicles. Jefferies committed to invest equity in private equity funds (the "JCP Funds") managed by Jefferies Capital Partners, LLC (the "JCP Manager"). Additionally, Jefferies committed to invest equity in the general partners of the JCP Funds (the "JCP General Partners") and the JCP Manager. Jefferies variable interests in the JCP Funds, JCP General Partners and JCP Manager (collectively, the "JCP Entities") consist of equity interests that, in total, provide Jefferies with limited and general partner investment returns of the JCP Funds, a portion of the carried interest earned by the JCP General Partners and a portion of the management fees earned by the JCP Manager. Jefferies total equity commitment in the JCP Entities was $148.1 million, of which $126.3 million and $125.1 million has been funded as of December 31, 2017 and 2016, respectively. The carrying value of Jefferies equity investments in the JCP Entities was $23.7 million and $37.6 million at December 31, 2017 and 2016, respectively. Jefferies exposure to loss is limited to the total of its carrying value and unfunded equity commitment. The assets of the JCP Entities primarily consist of private equity and equity related investments.

Jefferies has also provided a guarantee of a portion of Energy Partners I, LP's obligations under a credit agreement (“Energy Partners Credit Agreement”). Energy Partners I, LP is a private equity fund owned and managed by certain of our employees. The maximum exposure to loss of the guarantee was $3.0 million as of December 31, 2016.  Energy Partners I, LP has assets consisting primarily of debt and equity investments. The Energy Partners Credit Agreement was terminated in April 2017.

Real Estate Investment Vehicles. 54 Madison has committed to invest $98.0 million in real estate investment vehicles, of which $86.5 million was funded as of December 31, 2016. 54 Madison's maximum exposure to loss was limited to its carrying value and unfunded equity commitment. 54 Madison was not the primary beneficiary of the investment vehicles as it did not have the power to control the most important activities of the VIEs. The assets of the VIEs consisted primarily of investments in real estate projects. As a result of the sale of our interest in the general partner during 2017, the 54 Madison fund has been deconsolidated and is reflected in Loans to and investments in associated companies at December 31, 2017.

Other Private Investment Vehicles.  The carrying amount of our equity investment was $133.0 million and $84.0 million at December 31, 2017 and 2016, respectively. Our unfunded equity commitment related to these investments totaled $9.1 million and $11.8 million at December 31, 2017 and 2016, respectively. Our exposure to loss is limited to the total of our carrying value and unfunded equity commitment. These private investment vehicles have assets primarily consisting of private and public equity investments, debt instruments and various oil and gas assets.

Mortgage- and Other Asset-Backed Securitization Vehicles.  In connection with Jefferies secondary trading and market-making activities, Jefferies buys and sells agency and non-agency mortgage-backed securities and other asset-backed securities, which are issued by third party securitization SPEs and are generally considered variable interests in VIEs. Securities issued by securitization SPEs are backed by residential mortgage loans, U.S. agency collateralized mortgage obligations, commercial mortgage loans, CDOs and CLOs and other consumer loans, such as installment receivables, auto loans and student loans. These securities are accounted for at fair value and included in Trading assets in our Consolidated Statements of Financial Condition. Jefferies has no other involvement with the related SPEs and therefore does not consolidate these entities.

Jefferies also engages in underwriting, placement and structuring activities for third-party-sponsored securitization trusts generally through agency (FNMA ("Fannie Mae"), Federal Home Loan Mortgage Corporation ("Freddie Mac") or GNMA ("Ginnie Mae")) or non-agency-sponsored SPEs and may purchase loans or mortgage-backed securities from third parties that are subsequently transferred into the securitization trusts. The securitizations are backed by residential and commercial mortgage, home equity and auto loans. Jefferies does not consolidate agency-sponsored securitizations as it does not have the power to direct the activities of the SPEs that most significantly impact their economic performance. Further, Jefferies is not the servicer of non-agency-sponsored securitizations and therefore does not have power to direct the most significant activities of the SPEs and accordingly, does not consolidate these entities. Jefferies may retain unsold senior and/or subordinated interests at the time of securitization in the form of securities issued by the SPEs.

Jefferies transfers existing securities, typically mortgage-backed securities, into resecuritization vehicles. These transactions in which debt securities are transferred to a VIE in exchange for new beneficial interests occur in connection with both agency and non-agency-sponsored VIEs. The consolidation analysis is largely dependent on Jefferies role and interest in the resecuritization trusts. Most resecuritizations in which Jefferies is involved are in connection with investors seeking securities with specific risk and return characteristics. As such, Jefferies has concluded that the decision-making power is shared between Jefferies and the investor(s), considering the joint efforts involved in structuring the trust and selecting the underlying assets as well as the level of security interests the investor(s) hold in the SPE; therefore, Jefferies does not consolidate the resecuritization VIEs.

At December 31, 2017 and 2016, Jefferies held $1,829.6 million and $1,002.2 million of agency mortgage-backed securities, respectively, and $253.2 million and $439.4 million of non-agency mortgage- and other asset-backed securities, respectively, as a result of its secondary trading and market-making activities, underwriting, placement and structuring activities and resecuritization activities. Jefferies maximum exposure to loss on these securities is limited to the carrying value of its investments in these

F-51

securities. Mortgage- and other asset-backed securitization vehicles discussed within this section are not included in the above table containing information about Jefferies variable interests in nonconsolidated VIEs.

We also have a variable interest in a nonconsolidated VIE consisting of our equity interest in an associated company, Golden Queen. In addition, we have a variable interest in a nonconsolidated VIE consisting of our senior secured term loan receivable and equity interest in FXCM.  See Notes 4 and 10 for further discussion.

(1) Primarily classified in Investment banking revenues and Other revenues.

(2) On October 31, 2017, Jefferies sold all of its membership interests in Jefferies LoanCore for approximately $173.1 million.

(3) At December 31, 2017, 2016 and 2015, the balance reflects $30.5 million, $32.8 million and $33.7 million, respectively, related to a noncontrolling interest.

(4) At December 31, 2016, the balance reflects $95.3 million related to noncontrolling interests.

(5) As discussed further below, on November 30, 2017, we sold our interest in the general partner of the 54 Madison fund and as a result no longer control the 54 Madison investment committee. We retained two of the four seats on the investment committee and continue to have significant influence over the fund. We therefore deconsolidated the 54 Madison fund and account for our interest under the equity method of accounting.

(6) As discussed more fully in Note 4, in 2016, we amended the terms of our loan and associated rights with FXCM. Through the amendments, we converted our participation rights for a 50% voting interest in FXCM. Our term loan remains classified within Trading assets, at fair value.

Jefferies Finance

Jefferies Finance, a joint venture entity pursuant to an agreement with Massachusetts Mutual Life Insurance Company ("MassMutual"), is a commercial finance company whose primary focus is the origination and syndication of senior secured debt to middle market and growth companies in the form of term and revolving loans. Loans are originated primarily through the investment banking efforts of Jefferies. Jefferies Finance may also originate other debt products such as second lien term, bridge and mezzanine loans, as well as related equity co-investments. Jefferies Finance also purchases syndicated loans in the secondary market and acts as an investment advisor for various loan funds.

At December 31, 2017, Jefferies and MassMutual each had equity commitments to Jefferies Finance of $750.0 million. At December 31, 2017, approximately $636.2 million of Jefferies commitment was funded. The investment commitment is scheduled to expire on March 1, 2018 with automatic one year extensions absent a 60-day termination notice by either party.

In addition, Jefferies and MassMutual have entered into a Secured Revolving Credit Facility, to be funded equally, to support loan underwritings by Jefferies Finance, which bears interest based on the interest rates of the related Jefferies Finance underwritten loans and is secured by the underlying loans funded by the proceeds of the facility. The total Secured Revolving Credit Facility is for a total committed amount of $500.0 million at December 31, 2017 and 2016. Advances are shared equally between Jefferies and MassMutual. The facility is scheduled to mature on March 1, 2018 with automatic one year extensions absent a 60-day termination notice by either party. At December 31, 2017, none of Jefferies $250.0 million commitment was funded. Jefferies recognized interest income and unfunded commitment fees related to the facility of $3.9 million, $1.3 million and $2.5 million during 2017, 2016 and 2015, respectively.

Jefferies engages in debt capital markets transactions with Jefferies Finance related to the originations and syndications of loans by Jefferies Finance. In connection with such services, Jefferies earned fees of $327.9 million, $112.6 million and $122.7 million during 2017, 2016 and 2015, respectively, which are recognized in Investment banking revenues in the Consolidated Statements of Operations. In addition, Jefferies paid fees to Jefferies Finance in respect of certain loans originated by Jefferies Finance of

F-53

$2.4 million, $0.5 million and $5.9 million during 2017, 2016 and 2015, respectively, which are recognized within Selling, general and other expenses in the Consolidated Statements of Operations.

During the years ended December 31, 2017, 2016 and 2015, Jefferies acted as a placement agent for CLOs managed by Jefferies Finance, for which Jefferies recognized fees of $6.1 million, $2.6 million and $6.2 million, respectively, which are included in Investment banking revenues in the Consolidated Statements of Operations. At December 31, 2017 and 2016, Jefferies held securities issued by CLOs managed by Jefferies Finance, which are included in Trading assets. At December 31, 2016, Jefferies provided a guarantee, whereby Jefferies is required to make certain payments to a CLO in the event Jefferies Finance was unable to meet its obligations to the CLO. The CLO was terminated in October 2017. Additionally, Jefferies has entered into participation agreements and derivative contracts with Jefferies Finance based upon certain securities issued by the CLO. Gains (losses) related to the derivative contracts were not material.

Jefferies acted as underwriter in connection with senior notes issued by Jefferies Finance, for which Jefferies recognized underwriting fees of $1.3 million during the year ended December 31, 2015, which are included in Investment banking revenues in the Consolidated Statements of Operations.

Under a service agreement, Jefferies charged Jefferies Finance $50.7 million, $46.1 million and $51.7 million for services provided during 2017, 2016 and 2015, respectively. At December 31, 2017, Jefferies had a receivable from Jefferies Finance, included within Other assets in the Consolidated Statement of Financial Condition of $34.6 million and a payable to Jefferies Finance, included in Payables, expense accruals and other liabilities in the Consolidated Statement of Financial Condition of $14.1 million. At December 31, 2016, Jefferies had a payable to Jefferies Finance, included in Payables, expense accruals and other liabilities in the Consolidated Statement of Financial Condition of $5.8 million.

Jefferies enters into OTC foreign exchange contracts with Jefferies Finance as to which, at December 31, 2017, we had $1.5 million included in Trading assets in our Consolidated Statements of Financial Condition.

Jefferies LoanCore

Jefferies LoanCore, a commercial real estate finance company and a joint venture with the Government of Singapore Investment Corporation, the Canada Pension Plan Investment Board and LoanCore, LLC, originates and purchases commercial real estate loans throughout the U.S. and Europe. On October 31, 2017, Jefferies sold all of its membership interests (which constituted a 48.5% voting interest) in Jefferies LoanCore for approximately $173.1 million, the estimated book value as of October 31, 2017. In addition, Jefferies may be entitled to additional cash consideration over the next five years in the event Jefferies LoanCore's yearly return on equity exceeds certain thresholds.

Jefferies LoanCore had entered into master repurchase agreements with Jefferies. During 2017, 2016 and 2015, Jefferies recognized interest income and fees related to these agreements of $0.6 million, $8.4 million and $10.7 million, respectively. In connection with such master repurchase agreements, at December 31, 2016, Jefferies had securities purchased with agreements to resell from Jefferies LoanCore of $68.1 million. Jefferies also enters into OTC foreign exchange contracts with Jefferies LoanCore. In connection with these contracts, Jefferies had $8.3 million at December 31, 2016 recorded in Payables, expense accruals and other liabilities in the Consolidated Statement of Financial Condition.

Berkadia

Berkadia is a commercial mortgage banking and servicing joint venture formed in 2009 with Berkshire Hathaway Inc. We and Berkshire Hathaway each contributed $217.2 million of equity capital to the joint venture and each have a 50% equity interest in Berkadia. Through December 31, 2017, cumulative cash distributions received by Leucadia from this investment aggregated $562.0 million. Berkadia originates commercial/multifamily real estate loans that are sold to U.S. government agencies, and originates and brokers commercial/multifamily mortgage loans which are not part of government agency programs. Berkadia is an investment sales advisor focused on the multifamily industry. Berkadia is a servicer of commercial real estate loans in the U.S., performing primary, master and special servicing functions for U.S. government agency programs, commercial mortgage-backed securities transactions, banks, insurance companies and other financial institutions.

Berkadia uses all of the proceeds from the commercial paper sales of an affiliate of Berkadia to fund new mortgage loans, servicer advances, investments and other working capital requirements. Repayment of the commercial paper is supported by a $1.5 billion surety policy issued by a Berkshire Hathaway insurance subsidiary and corporate guaranty, and we have agreed to reimburse Berkshire Hathaway for one-half of any losses incurred thereunder. As of December 31, 2017, the aggregate amount of commercial paper outstanding was $1.47 billion.

FXCM

As discussed more fully in Note 4, at December 31, 2017, Leucadia has a 50% voting interest in FXCM and a senior secured term loan to FXCM due January 2018. On September 1, 2016, we gained the ability to significantly influence FXCM through our seats on the board of directors. As a result, we classify our equity investment in FXCM in our Consolidated Statements of Financial Condition as Loans to and investments in associated companies. Our term loan remains classified within Trading assets, at fair value. We account for our equity interest in FXCM on a one month lag. We are amortizing our basis difference between the estimated fair value and the underlying book value of FXCM customer relationships, technology, trade name, leases and long-term debt over their respective useful lives.

Based on the February 2017 actions described further in Note 4, we evaluated in the first quarter of 2017 whether our equity method investment was fully recoverable. We engaged an independent valuation firm to assist management in estimating the fair value of FXCM. Our estimate of fair value was based on a discounted cash flow and comparable public company analysis. The result of our analysis indicated that the estimated fair value of our equity interest in FXCM was lower than our carrying value by $130.2 million. We concluded based on the regulatory actions, FXCM's restructuring plan described further in Note 4, investor perception and declines in the trading price of Global Brokerage's common shares and convertible debt, that the decline in fair value of our equity interest was other than temporary. As such, we impaired our equity investment in FXCM in the first quarter of 2017 by $130.2 million.

FXCM is considered a VIE and our term loan and equity interest are variable interests. We have determined that we are not the primary beneficiary of FXCM because we do not have the power to direct the activities that most significantly impact FXCM's performance. Therefore, we do not consolidate FXCM.

Garcadia

Garcadia is a joint venture between us and Garff Enterprises, Inc. ("Garff") that owns and operates 28 automobile dealerships comprised of domestic and foreign automobile makers. The Garcadia joint venture agreement specifies that we and Garff shall have equal board representation and equal votes on all matters affecting Garcadia, and that all operating cash flows from Garcadia will be allocated 65% to us and 35% to Garff, with the exception of one dealership from which we receive 83% of all operating cash flows and four other dealerships from which we receive 71% of all operating cash flows. Garcadia’s strategy is to acquire automobile dealerships in primary or secondary market locations meeting its specified return criteria. 

Linkem

We own approximately 42% of the common shares of Linkem, a fixed wireless broadband services provider in Italy. In addition, we own 5% convertible preferred stock, which is automatically convertible to common shares in 2020. If all of our convertible preferred stock was converted, it would increase our ownership to approximately 53% of Linkem’s common equity at December 31, 2017. We have approximately 48% of the total voting securities of Linkem. The excess of our investment in Linkem’s common shares over our share of underlying book value is being amortized to expense over 12 years.

HomeFed

At December 31, 2017, we own 10,852,123 shares of HomeFed’s common stock, representing approximately 70% of HomeFed’s outstanding common shares; however, we have contractually agreed to limit our voting rights such that we will not be able to vote more than 45% of HomeFed’s total voting securities voting on any matter, assuming all HomeFed shares not owned by us are voted. HomeFed develops and owns residential and mixed-use real estate properties. HomeFed is a public company traded on the NASD OTC Bulletin Board (Symbol: HOFD). As a result of a 1998 distribution to all of our shareholders, approximately 4.8% of HomeFed is beneficially owned by our Chairman at December 31, 2017. Three of our executives serve on the board of directors of HomeFed, including our Chairman who serves as HomeFed’s Chairman, and our President. Since we do not control HomeFed, our investment in HomeFed is accounted for under the equity method as an investment in an associated company.

Golden Queen Mining Company

During 2014 and 2015, we invested $83.0 million, net in cash in a limited liability company (Gauss LLC) to partner with the Clay family and Golden Queen Mining Co. Ltd., to jointly fund, develop and operate the Soledad Mountain gold and silver mine project. Previously 100% owned by Golden Queen Mining Co. Ltd., the project is a fully-permitted, open pit, heap leach gold and silver project located in Kern County, California, which commenced gold and silver production in March 2016. In exchange for a noncontrolling ownership interest in Gauss LLC, the Clay family contributed $34.5 million, net in cash. Gauss LLC invested both our and the Clay family’s net contributions totaling $117.5 million to the joint venture, Golden Queen, in exchange for a 50%

F-55

ownership interest. Golden Queen Mining Co. Ltd. contributed the Soledad Mountain project to the joint venture in exchange for the other 50% interest.

As a result of our consolidating Gauss LLC, our Loans to and investments in associated companies reflects Gauss LLC’s net investment of $117.5 million in the joint venture, which includes both the amount we contributed and the amount contributed by the Clay family. The joint venture, Golden Queen, is considered a VIE as the voting rights of the investors are not proportional to their obligations to absorb the expected losses and their rights to receive the expected residual returns, given the provision of services to the joint venture by Golden Queen Mining Co. Ltd. Golden Queen Mining Co. Ltd. has entered into an agreement with the joint venture for the provision of executive officers, financial, managerial, administrative and other services, and office space and equipment. We have determined that we are not the primary beneficiary of the joint venture and are therefore not consolidating its results.

Our maximum exposure to loss as a result of our involvement with the joint venture is limited to our investment. The excess of Gauss LLC's investment in Golden Queen's underlying book value is being amortized to expense over the estimated life of mine gold and silver sales.

54 Madison

We own approximately 48.1% of 54 Madison, a fund that seeks long-term capital appreciation through investment in real estate development and similar projects. Prior to November 30, 2017, we consolidated 54 Madison as a result of our control of the 54 Madison investment committee. 54 Madison invests both in projects which they consolidate and projects where they have significant influence and utilize the equity method of accounting. Based on total committed capital of the 54 Madison fund, all projects of this fund have already been identified and launched. On November 30, 2017, we sold our interest in the general partner of the 54 Madison fund and as a result no longer control the 54 Madison investment committee. We retained two of the four seats on the 54 Madison investment committee and continue to have significant influence over the fund, including a number of protective rights such as the right to block material investments, divestitures and changes outside of agreed upon parameters. We therefore deconsolidated the 54 Madison fund on November 30, 2017 and account for our interest under the equity method of accounting. We account for our equity interest in the 54 Madison fund on a one quarter lag.

Note 11.  Financial Statement Offsetting

In connection with Jefferies derivative activities and securities financing activities, Jefferies may enter into master netting agreements and collateral arrangements with counterparties. Generally, transactions are executed under standard industry agreements, including, but not limited to: derivative transactions – ISDA master netting agreements; securities lending transactions – master securities lending agreements; and repurchase transactions – master repurchase agreements. A master agreement creates a single contract under which all transactions between two counterparties are executed allowing for trade aggregation and a single net payment obligation. Master agreements provide protection in bankruptcy in certain circumstances and, where legally enforceable, enable receivables and payables with the same counterparty to be settled or otherwise eliminated by applying amounts due to a counterparty against all or a portion of an amount due from the counterparty or a third party. 

Under Jefferies derivative ISDA master netting agreements, Jefferies typically will also execute credit support annexes, which provide for collateral, either in the form of cash or securities, to be posted by or paid to a counterparty based on the fair value of the derivative receivable or payable based on the rates and parameters established in the credit support annex. In the event of the counterparty’s default, provisions of the master agreement permit acceleration and termination of all outstanding transactions covered by the agreement such that a single amount is owed by, or to, the non-defaulting party. In addition, any collateral posted can be applied to the net obligations, with any excess returned; and the collateralized party has a right to liquidate the collateral. Any residual claim after netting is treated along with other unsecured claims in bankruptcy court.

The conditions supporting the legal right of offset may vary from one legal jurisdiction to another and the enforceability of master netting agreements and bankruptcy laws in certain countries or in certain industries is not free from doubt. The right of offset is dependent both on contract law under the governing arrangement and consistency with the bankruptcy laws of the jurisdiction where the counterparty is located. Industry legal opinions with respect to the enforceability of certain standard provisions in respective jurisdictions are relied upon as a part of managing credit risk. In cases where Jefferies has not determined an agreement to be enforceable, the related amounts are not offset. Master netting agreements are a critical component of Jefferies risk management processes as part of reducing counterparty credit risk and managing liquidity risk.

Jefferies is also a party to clearing agreements with various central clearing parties. Under these arrangements, the central clearing counterparty facilitates settlement between counterparties based on the net payable owed or receivable due and, with respect to daily settlement, cash is generally only required to be deposited to the extent of the net amount. In the event of default, a net termination amount is determined based on the market values of all outstanding positions and the clearing organization or clearing member provides for the liquidation and settlement of the net termination amount among all counterparties to the open contracts or transactions.

(1) Under master netting agreements with our counterparties, we have the legal right of offset with a counterparty, which incorporates all of the counterparty’s outstanding rights and obligations under the arrangement. These balances reflect additional credit risk mitigation that is available by a counterparty in the event of a counterparty’s default, but which are not netted in the balance sheet because other provisions of GAAP are not met. Further, for derivative assets and liabilities, amounts netted include cash collateral paid or received.

Goodwill Impairment Testing

The quantitative goodwill impairment test is performed at our reporting unit level and consists of two steps. In the first step, the fair value of the reporting unit is compared with its carrying value, including goodwill and allocated intangible assets. If the fair value is in excess of the carrying value, the goodwill for the reporting unit is considered not to be impaired. If the fair value is less than the carrying value, then a second step is performed in order to measure the amount of the impairment loss, if any, which is based on comparing the implied fair value of the reporting unit’s goodwill to the carrying value of the reporting unit's goodwill. 

The estimated fair values are based on valuation techniques that we believe market participants would use, although the valuation process requires significant judgment and often involves the use of significant estimates and assumptions. The methodologies we utilize in estimating fair value include price-to-earnings and price-to-book multiples of comparable public companies, multiples of mergers and acquisitions of similar businesses, projected cash flows and/or market capitalization. In addition, as the fair values determined under the market approach represent a noncontrolling interest, we applied a control premium to arrive at the estimated fair value of our reporting units on a controlling basis. An independent valuation specialist was engaged to assist with the valuation process for Jefferies at August 1, 2017. The results of our annual impairment test related to Jefferies, National Beef and other operations indicated goodwill was not impaired.

(1) Bank loans include loans entered into, pursuant to a Master Loan Agreement, between the Bank of New York and Jefferies.

At December 31, 2017 and 2016, the weighted average interest rate on short-term borrowings outstanding was 2.51% and 1.77% per annum, respectively.

During the year ended December 31, 2017, Jefferies issued equity-linked notes with a principal amount of $30.6 million which matured in July 2017 and $4.2 million, which matured in September 2017. The remaining equity-linked notes will mature in the first quarter of 2018. See Note 4 for further information. During 2016, Jefferies issued floating rate puttable notes with an aggregate principal amount of €91.0 million.

The Bank of New York Mellon agrees to make revolving intraday credit advances (“Intraday Credit Facility”) for an aggregate committed amount of $150.0 million. The Intraday Credit Facility contains a financial covenant, which includes a minimum regulatory net capital requirement. Interest is based on the higher of the Federal funds effective rate plus 0.5% or the prime rate. At December 31, 2017, Jefferies was in compliance with debt covenants under the Intraday Credit Facility.

In December 2015, Jefferies entered into a secured revolving loan facility (“Secured Revolving Loan Facility”) whereby the lender agreed to make available a revolving loan facility in a maximum principal amount of $50.0 million to purchase eligible receivables that met certain requirements as defined in the Secured Revolving Loan Facility agreement. Interest was based on an annual rate equal to the lesser of the LIBOR rate plus 4.25% or the maximum rate as defined in the Secured Revolving Loan Facility agreement. The Secured Revolving Loan Facility was terminated effective January 24, 2017.

Parent Company Debt

Our senior note indentures contain covenants that restrict our ability to incur more Indebtedness or issue Preferred Stock of Subsidiaries unless, at the time of such incurrence or issuance, the Company meets a specified ratio of Consolidated Debt to Consolidated Tangible Net Worth, limit the ability of the Company and Material Subsidiaries to incur, in certain circumstances, Liens, limit the ability of Material Subsidiaries to incur Funded Debt in certain circumstances, and contain other terms and restrictions all as defined in the senior note indentures. We have the ability to incur substantial additional indebtedness or make distributions to our shareholders and still remain in compliance with these restrictions. If we are unable to meet the specified ratio, we would not be able to issue additional Indebtedness or Preferred Stock, but our inability to meet the applicable ratio would not result in a default under our senior note indentures. The senior note indentures do not restrict the payment of dividends.

Subsidiary Debt

During 2017, $20.2 million of Jefferies 3.875% Convertible Senior Debentures due 2029 (original principal amount of $345.0 million) were called. In November 2017, all of the remaining 3.875% Convertible Senior Debentures were called for optional redemption, with a redemption date of January 5, 2018, at a redemption price equal to 100% of the principal amount of the convertible debentures redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. All of these remaining convertible debentures were redeemed in January 2018.

During the year ended December 31, 2017, Jefferies issued structured notes with a total principal amount of approximately $329.9 million, net of retirements. Structured notes of $607.0 million and $248.9 million at December 31, 2017 and 2016, respectively, contain various interest rate payment terms and are accounted for at fair value, with changes in fair value resulting from a change in the instrument-specific credit risk presented in Accumulated other comprehensive income and changes in fair value resulting from non-credit components recognized in Principal transaction revenues.

In January 2018, Jefferies issued 4.15% senior notes with a principal amount of $1.0 billion, due 2030. In January 2017, Jefferies issued 4.85% senior notes with a principal amount of $750.0 million, due 2027.

In June 2017, National Beef entered into a Third Amended and Restated Credit Agreement (the "Debt Agreement"). The Debt Agreement matures in June 2022 and includes a $275.0 million reducing revolver loan and a $275.0 million revolving credit facility. The reducing revolver loan commitment decreases by $13.8 million on each annual anniversary of the Debt Agreement. The Debt Agreement is secured by a first priority lien on substantially all of the assets of National Beef and its subsidiaries and includes customary covenants including a single financial covenant that requires National Beef to maintain a minimum tangible net worth as defined in the Debt Agreement; at December 31, 2017, National Beef was in compliance with the covenants.

At December 31, 2017, National Beef’s outstanding debt under the Debt Agreement consisted of a reducing revolver loan with an outstanding balance of $120.0 million and $80.0 million drawn on the revolving credit facility. The reducing revolver loan and the revolving credit facility bear interest at the Base Rate or the LIBOR Rate (as defined in the Debt Agreement), plus a margin ranging from .75% to 2.75% depending upon certain financial ratios and the rate selected. At December 31, 2017, the interest rate on the outstanding reducing revolver loan was 3.3% and the interest rate on the outstanding revolving credit facility was 3.3%. 

Borrowings under the reducing revolver loan and the revolving credit facility are available for National Beef’s working capital requirements, capital expenditures and other general corporate purposes. Unused capacity under the revolving credit facility can also be used to issue letters of credit; letters of credit aggregating $13.9 million were outstanding at December 31, 2017. Amounts available under the revolving credit facility are subject to a borrowing base calculation primarily comprised of receivable and inventory balances; amounts available under the reducing revolver facility are constrained only by the annual reduction in the commitment amount. At December 31, 2017, after deducting outstanding amounts and issued letters of credit, $87.1 million of the unused revolving credit facility and $155.0 million of the reducing revolver commitment was available to National Beef.

54 Madison seeks long-term capital appreciation through real estate development and similar projects. Many of these development projects are funded through long-term debt at the project level. The debt holders do not have recourse to the Leucadia parent company. As discussed further in Note 10, due to the sale of our interest in the general partner of the 54 Madison fund, the 54 Madison fund and its long-term debt was deconsolidated during 2017.

At December 31, 2017, Foursight Capital’s credit facilities consisted of two warehouse credit commitments aggregating $225.0 million, which mature in March 2019 and July 2020. The 2019 credit facility bears interest based on the three-month LIBOR plus a credit spread fixed through its maturity and the 2020 credit facility bears interest based on the one-month LIBOR plus a credit spread fixed through its maturity. As a condition of the 2019 credit facility, Foursight Capital is obligated to maintain cash reserves in an amount equal to the quoted price of an interest rate cap sufficient to meet the hedging requirements of the credit commitment.

F-62

The credit facilities are secured by first priority liens on auto loan receivables owed to Foursight Capital of approximately $200.5 million at December 31, 2017.

Note 16.  Mezzanine Equity

Redeemable Noncontrolling Interests

Redeemable noncontrolling interests primarily relate to National Beef and are held by its minority owners, USPB, NBPCo Holdings and the chief executive officer of National Beef. The holders of these interests share in the profits and losses of National Beef on a pro rata basis with us. However, the minority owners have the right to require us to purchase their interests under certain specified circumstances at fair value (put rights), and we also have the right to purchase their interests under certain specified circumstances at fair value (call rights). Holders of the put rights had from December 30, 2016 through January 29, 2017 to make an election that would require us to purchase up to one-third of their interests. The holders of the put rights did not make such election. The holders will again have the right to make an election that requires us to purchase up to one-third on December 30, 2018, and the remainder on December 30, 2021. In addition, USPB may elect to exercise their put rights following the termination of the cattle supply agreement, and the chief executive officer following the termination of his employment.

Our call rights with respect to USPB may be exercised following the termination of the cattle supply agreement or after USPB’s ownership interest is less than 20% of their interest held at the time we acquired National Beef. Our call rights with respect to other members may be exercised after the ten year anniversary of our acquisition of National Beef if such member’s ownership interest is less than 50% of the interest held at the time we acquired National Beef. Additionally, we may acquire the chief executive officer’s interest following the termination of his employment.

Redeemable noncontrolling interests in National Beef are reflected in the Consolidated Statements of Financial Condition at fair value. The following table rolls forward National Beef’s redeemable noncontrolling interests activity during the years ended December 31, 2017 and 2016 (in thousands):

	2017			2016
As of January 1,	$	321,962		$	189,358
Income allocated to redeemable noncontrolling interests	85,277			68,811
Distributions to redeemable noncontrolling interests	(90,048		)	(53,701		)
Increase in fair value of redeemable noncontrolling interests charged to additional paid-in capital	94,937			117,494
Balance, December 31,	$	412,128		$	321,962

At acquisition, we prepared a projection of future cash flows of National Beef, which was used along with other information to allocate the purchase price to National Beef’s individual assets and liabilities. At December 31, 2017, we calculated the fair value of the redeemable noncontrolling interests by updating our estimate of future cash flows. The projected future cash flows consider estimated revenue growth, cost of sales changes, capital expenditures and other unobservable inputs. However, the most significant unobservable inputs affecting the estimate of fair value are the discount rate (12.20%) and the terminal growth rate (2.00%) used to calculate the capitalization rate of the terminal value.

The table below is a sensitivity analysis which shows the fair value of the redeemable noncontrolling interests using the assumed discount and the terminal growth rates and fair values under different rate assumptions as of December 31, 2017 (dollars in millions):

		Discount Rates
Terminal Growth Rates		11.95%		12.20%		12.45%
1.75	%	$	417.6	$	407.6	$	398.1
2.00	%	$	422.4	$	412.1	$	402.3
2.25	%	$	427.5	$	416.9	$	406.8

The projection of future cash flows is updated with input from National Beef personnel. The estimate is reviewed by personnel at our corporate office as part of the normal process for the preparation of our quarterly and annual financial statements.

F-63

At December 31, 2017 and 2016, redeemable noncontrolling interests also includes other redeemable noncontrolling interests of $14.5 million and $14.8 million, respectively, primarily related to our oil and gas production and development businesses.

Mandatorily Redeemable Convertible Preferred Shares

In connection with our acquisition of Jefferies in March 2013, we issued a new series of 3.25% Cumulative Convertible Preferred Shares (“Preferred Shares”) ($125.0 million at mandatory redemption value) in exchange for Jefferies outstanding 3.25% Series A-1 Cumulative Convertible Preferred Stock. The Preferred Shares have a 3.25% annual, cumulative cash dividend and are currently convertible into 4,162,200 common shares, an effective conversion price of $30.03 per share. The holders of the Preferred Shares are also entitled to an additional quarterly payment in the event we declare and pay a dividend on our common stock in an amount greater than $0.0625 per common share per quarter. The additional quarterly payment would be paid to the holders of Preferred Shares on an as converted basis and on a per share basis would equal the quarterly dividend declared and paid to a holder of a share of common stock in excess of $0.0625 per share. In the third quarter of 2017, we increased our quarterly dividend from $0.0625 to $0.10 per common share. This increased the preferred stock dividend from $4.1 million for the year ended December 31, 2016 to $4.4 million for the year ended December 31, 2017. The Preferred Shares are callable beginning in 2023 at a price of $1,000 per share plus accrued interest and are mandatorily redeemable in 2038.

Note 17.  Compensation Plans

Incentive Plan

Upon completion of our combination with Jefferies, we assumed its 2003 Incentive Compensation Plan, as Amended and Restated July 25, 2013 (the "Incentive Plan"). The Incentive Plan allows awards in the form of incentive stock options (within the meaning of Section 422 of the Internal Revenue Code), nonqualified stock options, stock appreciation rights, restricted stock, unrestricted stock, performance awards, restricted stock units ("RSUs"), dividend equivalents or other share-based awards.

RSUs give a participant the right to receive fully vested shares at the end of a specified deferral period allowing a participant to hold an interest tied to common stock on a tax deferred basis. Prior to settlement, RSUs carry no voting or dividend rights associated with the stock ownership, but dividend equivalents are accrued to the extent there are dividends declared on the underlying common shares as cash amounts or as deemed reinvestments in additional RSUs.

Restricted stock and RSUs may be granted to new employees as "sign-on" awards, to existing employees as "retention" awards and to certain executive officers as awards for multiple years. Sign-on and retention awards are generally subject to annual ratable vesting over a four-year service period and are amortized as compensation expense on a straight-line basis over the related four years. Restricted stock and RSUs are granted to certain senior executives with market, performance and service conditions. Market conditions are incorporated into the grant-date fair value of senior executive awards using a Monte Carlo valuation model. Compensation expense for awards with market conditions is recognized over the service period and is not reversed if the market condition is not met. Awards with performance conditions are amortized over the service period if it is determined that it is probable that the performance condition will be achieved. Awards granted to senior executives related to the 2015 fiscal year did not meet performance targets, and as a result, compensation expense has been adjusted to reflect the reduced number of shares that have vested.

The Deferred Compensation Plan (the “DCP”) has been implemented under the Incentive Plan. The DCP permits eligible executive officers and other employees to defer cash compensation, some or all of which may be deemed invested in stock units. A portion of the deferrals may also be directed to notional investments in a money market fund or certain of the employee investment opportunities. Stock units generally have been acquired at a discounted price, which encourages employee participation in the DCP and enhances long-term retention of equity interests by participants and aligns executive interests with those of shareholders.  Amounts recognized as compensation cost under the DCP have not been significant. The shares to be delivered in connection with DCP stock units and options are drawn from the Incentive Plan.

The Incentive Plan’s “evergreen” share reservation was terminated on March 21, 2014; the number of equity awards available under the Incentive Plan was set at 20,000,000. At December 31, 2017, 11,883,293 common shares remained available for new grants under the Incentive Plan. Shares issued pursuant to the DCP reduce the shares available under the Incentive Plan.

Senior Executive Compensation Plan

In February 2016, the Compensation Committee of our Board of Directors approved an executive compensation plan for our CEO and our President (together, our "Senior Executives") in respect of 2016 (the "2016 Plan") that is based on performance metrics achieved over a three-year period from 2016 through 2018. The Compensation Committee eliminated cash incentive bonuses for 2016 and 100% of each of our CEO and President's compensation beyond their base salaries is composed entirely of performance based RSUs that vest at the end of 2018 if certain performance criteria are met. Any vested RSUs will be subject to a post-vesting, three-year holding period such that no vested RSUs can be sold or transferred until the first quarter of 2022.

Performance-vesting of the award is based equally on the compound annual growth rates of Leucadia's Total Shareholder Return ("TSR"), which is measured from the December 31, 2015 stock price of $17.39, and Leucadia's Return on Tangible Deployable Equity ("ROTDE"), the annual, two- and three-year results of which is used to determine vesting. TSR is based on annualized rate of return reflecting price appreciation plus reinvestment of dividends and distributions to shareholders. ROTDE is net income adjusted for amortization of intangible assets divided by tangible book value at the beginning of year adjusted for intangible assets and deferred tax assets.

In January 2017, the Compensation Committee of our Board of Directors approved an executive compensation plan for our Senior Executives in respect of 2017 (the "2017 Plan") that is based on performance metrics achieved over a three-year period from 2017 through 2019. This executive compensation plan is identical to the 2016 Plan, described above, where cash incentive bonuses were eliminated. 100% of each of our CEO and President's compensation beyond their base salaries is composed entirely of performance based RSUs that will vest at the end of 2019 if certain performance criteria are met. Any vested RSUs are subject to a post-vesting, three-year holding period such that no vested RSUs can be sold or transferred until the first quarter of 2023. Performance-vesting of the award is based equally on the compound annual growth rates of Leucadia's TSR, which is measured from the December 30, 2016 stock price of $23.25, and Leucadia's ROTDE, the annual, two- and three-year results of which are used to determine vesting.

If Leucadia's TSR and ROTDE annual compound growth rates are less than 4%, our Senior Executives will not receive any incentive compensation. If Leucadia's TSR and ROTDE grow between 4% and 8% on a compounded basis over the three-year measurement period, each of our Senior Executives will be eligible to receive between 846,882 and 1,693,766 RSUs related to the 2016 Plan and 537,634 and 1,075,268 RSUs related to the 2017 Plan. If TSR and ROTDE growth rates are greater than 8%, our Senior Executives are eligible to receive up to 50% additional incentive compensation on a pro rata basis up to 12% growth rates. When determining whether RSUs will vest, the calculation will be weighted equally between TSR and ROTDE. If TSR growth was below minimum thresholds, but ROTDE growth was above minimum thresholds, our Senior Executives would still be eligible to receive some number of vested RSUs based on ROTDE growth. The TSR award contains a market condition and compensation expense is recognized over the service period and will not be reversed if the market condition is not met. The ROTDE award contains a performance condition and compensation expense is recognized over the service period if it is determined that it is probable that the performance condition will be achieved.

The following table details the activity in RSUs related to the senior executive compensation plan during the years ended December 31, 2017 and 2016 (in thousands, except per share amounts):

	Target Number of Shares	Weighted- Average Grant Date Fair Value
Balance at December 31, 2015	—	$	—

The Compensation Committee of the Leucadia Board of Directors approved an executive compensation plan effective January 1, 2018 that extends Leucadia’s current compensation plans for our Senior Executives for compensation years 2018, 2019 and 2020. For each Senior Executive, the Compensation Committee has targeted long-term compensation of $25.0 million per year under the plan with a target of $16.0 million in long-term equity in the form of RSUs and a target of $9.0 million long-term cash, subject to performance targets over the three-year measurement period for each compensation year. To receive targeted long-term equity, our Senior Executives will have to achieve 8% growth on an annual and multi-year compounded basis in Leucadia’s TSR and to receive targeted long-term cash, our Senior Executives will have to achieve 8% growth on an annual and multi-year compounded basis in Leucadia’s ROTDE. If TSR and ROTDE are less than 5%, our Senior Executives will receive no long-term compensation. If TSR and ROTDE growth rates are greater than 8%, our Senior Executives are eligible to receive up to 50% additional incentive compensation on a pro rata basis up to 12% growth rates.

Directors’ Plan

Upon completion of our combination with Jefferies, we also assumed the 1999 Directors' Stock Compensation Plan, as Amended and Restated July 25, 2013 (the "Directors' Plan"). Under the Directors’ Plan, we issue each nonemployee director of Leucadia $120,000 of restricted stock or RSUs each year. These grants are made on the date directors are elected or reelected at our annual shareholders’ meeting. These shares vest over three years from the date of grant and are expensed over the requisite service period.  At December 31, 2017, 321,026 common shares were issuable upon settlement of outstanding RSUs and 297,926 shares are available for future grants.

Other Compensation Plans

Other Stock-Based Plans. Historically, Jefferies also sponsored an Employee Stock Purchase Plan and an Employee Stock Ownership Plan, both of which were assumed by us in connection with the Jefferies acquisition. Amounts related to these plans have not been significant.

Prior to the acquisition of Jefferies, we had two share-based compensation plans: a fixed stock option plan and a senior executive warrant plan.

• 1999 Stock Option Plan. This plan provided for the issuance of stock options and stock appreciation rights to non-employee directors and certain employees at not less than the fair market value of the underlying stock at the date of grant. Options granted to employees under this plan were intended to qualify as incentive stock options to the extent permitted under the Internal Revenue Code and became exercisable in five equal annual installments starting one year from date of grant. Options granted to non-employee directors became exercisable in four equal annual installments starting one year from date of grant. No stock appreciation rights have been granted. In March 2014, we ceased issuing options and rights under our option plan. No shares remain available for future grants under this plan.

• Senior Executive Warrant Plan.  The warrants to purchase 2,000,000 common shares that were granted in 2011 to each of our then Chairman and then President expired unexercised during the first quarter of 2016. We had recorded share-based compensation expense related to this grant of warrants of $1.0 million for the year ended December 31, 2015. No shares remain available for future grants under this warrant plan.

At December 31, 2017 and 2016, 331,312 and 641,478, respectively, of our common shares were reserved for stock options.

Restricted Cash Awards. Jefferies provides compensation to new and existing employees in the form of loans and/or other cash awards which are subject to ratable vesting terms with service requirements. These awards are amortized to compensation expense over the relevant service period. At December 31, 2017, the remaining unamortized amount of these awards was $481.6 million and is included within Other assets in the Consolidated Statement of Financial Condition.

Stock-Based Compensation Expense

Compensation and benefits expense included $48.4 million, $33.6 million and $74.1 millionfor the years ended December 31, 2017, 2016 and 2015, respectively, for share-based compensation expense relating to grants made under our share-based compensation plans. Total compensation cost includes the amortization of sign-on, retention and senior executive awards, less forfeitures and clawbacks. The total tax benefit recognized in results of operations related to share-based compensation expenses was $17.3 million, $12.4 million and $27.3 millionfor the years ended December 31, 2017, 2016 and 2015, respectively. As of December 31, 2017, total unrecognized compensation cost related to nonvested share-based compensation plans was $68.0 million; this cost is expected to be recognized over a weighted-average period of 1.7 years.

The net tax detriment related to share-based compensation plans recognized in additional paid-in capital was $4.2 million and $5.9 millionduring the years ended December 31, 2016 and 2015, respectively.

At December 31, 2017, there were 1,142,000 shares of restricted stock outstanding with future service required, 5,687,000 RSUs outstanding with future service required (including target RSUs issuable under the senior executive compensation plan), 10,313,000 RSUs outstanding with no future service required and 887,000 shares issuable under other plans. Excluding shares issuable pursuant to outstanding stock options, the maximum potential increase to common shares outstanding resulting from these outstanding awards is 16,887,000.

Note 19.  Pension Plans and Postretirement Benefits

U.S. Pension Plans

Pursuant to the agreement to sell one of our former subsidiaries, WilTel Communications Group, LLC, the responsibility for WilTel’s defined benefit pension plan was retained by us. All benefits under this plan were frozen as of October 30, 2005. Prior to the acquisition of Jefferies, Jefferies sponsored a defined benefit pension plan covering certain employees; benefits under that plan were frozen as of December 31, 2005.

Late in 2015, we launched a limited time voluntary lump sum offer to approximately 4,000 of the deferred vested participants of the WilTel plan. Approximately 2,400 participants accepted the lump sum offer and benefit payments totaling $110.7 million were paid out of plan assets. We also recorded a $40.7 million settlement charge in 2015 related to the participant acceptances.

As of December 31, 2017 and 2016, $51.3 million and $58.9 million, respectively, of the net amount recognized in the Consolidated Statements of Financial Condition was reflected as a charge to Accumulated other comprehensive income (substantially all of which were cumulative losses) and $60.5 million and $77.9 million, respectively, was reflected as accrued pension cost.

The following table summarizes the components of net periodic pension cost and other amounts recognized in other comprehensive income (loss) excluding taxes (in thousands):

	2017			2016			2015
Components of net periodic pension cost:

Net amount recognized in net periodic benefit cost and other comprehensive income (loss)	$	(5,023	)	$	7,686		$	(21,809	)

The amounts in Accumulated other comprehensive income at the end of each year have not yet been recognized as components of net periodic pension cost in the Consolidated Statements of Operations. The estimated net loss that will be amortized from accumulated other comprehensive income (loss) into net periodic benefit cost in 2018 is $2.5 million.

We expect to pay $8.9 million of employer contributions in 2018.

U.S. Plan Assets

The information below on the plan assets for the WilTel plan and the Jefferies plan is presented separately for the plans as the investments are managed independently. Cash equivalents are valued at cost, which approximates fair value and are categorized in Level 1 of the fair value hierarchy. The estimated fair values for securities measured using Level 1 inputs are determined using publicly quoted market prices in active markets for identical assets. Certain fixed income securities are measured using Level 2 inputs. Although these securities trade in brokered markets, the market for certain securities is sometimes inactive. Valuation inputs include benchmark yields, reported trades, broker dealer quotes, issuer spreads, two sided markets, benchmark securities, bids, offers, reference data, and industry and economic events. Neither plan had any assets classified within Level 3 of the fair value hierarchy.

WilTel Plan Assets.  At December 31, 2017 and 2016, the WilTel plan assets at fair value consisted of the following (in thousands):

			Fair Value Measurements Using
	Total		Level 1		Level 2

The current investment objectives are designed to close the funding gap while mitigating funded status volatility through a combination of liability hedging and investment returns. As plan funded status improves, the asset allocation will move along a predetermined, de-risking glide path that reallocates capital from growth assets to liability-hedging assets in order to reduce funded status volatility and lock in funded status gains. Plan assets are split into two separate portfolios, each with different asset mixes and objectives:

• The Growth Portfolio consists of global equities and high yield investments.

• The Liability-Driven Investing ("LDI") Portfolio consists of long duration credit bonds and a suite of long duration, Treasury-based instruments designed to provide capital-efficient interest rate exposure as well as target specific maturities. The objective of the LDI Portfolio is to seek to achieve performance similar to the WilTel plan's liability by seeking to match the interest rate sensitivity and credit sensitivity. The LDI Portfolio is managed to mitigate volatility in funded status deriving from changes in the discounted value of benefit obligations from market movements in the interest rate and credit components of the underlying discount curve.

To develop the assumption for the expected long-term rate of return on plan assets, we considered the following underlying assumptions: 2.25% current expected inflation, 1.0% to 1.5% real rate of return for long duration risk free investments and an additional 1.0% to 1.5% return premium for corporate credit risk. For U.S. and international equity, we assume an equity risk premium over cash equals to 4.0%. We then weighted these assumptions based on invested assets and assumed that investment expenses were offset by expected returns in excess of benchmarks, which resulted in the selection of the 7.0% expected long-term rate of return assumption for 2017.

Jefferies Plan Assets.  At December 31, 2017 and 2016, the Jefferies plan assets at fair value consisted of the following (in thousands):

Investment Policies and Strategies - Assets in the plan are invested under guidelines adopted by Jefferies Administrative Committee of the U.S. Pension Plan. Because the U.S. Pension Plan exists to provide a vehicle for funding future benefit obligations, the investment objectives of the portfolio take into account the nature and timing of future plan liabilities. The policy recognizes that the portfolio’s long-term investment performance and its ability to meet the plan’s overall objectives are dependent on the strategic asset allocation, which includes adequate diversification among assets classes.

In May 2017, Jefferies entered into an agreement with an external investment manager to invest and manage the plan’s assets under a strategy using a combination of two portfolios. The investment manager allocates the plan’s assets between a growth portfolio and a liability-driven portfolio according to certain target allocations and tolerance bands that are agreed to by Jefferies

F-72

Administrative Committee of the U.S. Pension Plan. Such target allocations will take into consideration the plan’s funded ratio. The manager will also monitor the strategy and, as the plan’s funded ratio changes over time, will rebalance the strategy, if necessary, to be within the agreed tolerance bands and target allocations. The portfolios are comprised of certain common collective investment trusts that are established and maintained by the investment manager.

German Pension Plan

In connection with the acquisition of Jefferies Bache from Prudential in 2011, Jefferies acquired a defined benefit pension plan located in Germany for the benefit of eligible employees of Jefferies Bache in that territory. The German pension plan has no plan assets and is therefore unfunded; however, Jefferies has purchased insurance contracts from multi-national insurers held in the name of Jefferies Bache Limited to provide for the plan’s future obligations. The investment in these insurance contracts is included in Financial instruments owned - Trading assets in the Consolidated Statements of Financial Condition and has a fair value of $16.0 million and $15.2 million at December 31, 2017 and 2016, respectively. All costs relating to the plan (including insurance premiums and other costs as computed by the insurers) are paid by Jefferies. In connection with the acquisition, Prudential agreed that any insurance premiums and funding obligations related to pre-acquisition date service will be reimbursed to Jefferies by Prudential.

On December 28, 2017, a Liquidation Insurance Contract was entered into between Jefferies Bache Limited and Generali Lebensversicherung AG ("Generali") to transfer the defined benefit pension obligations and insurance contracts to Generali, for approximately €6.5 million, which was paid in January 2018 and which will release Jefferies from any and all obligations under the German Pension Plan. Subject to certain precedent conditions being fulfilled, this transaction is expected to be completed in the first quarter of 2018. In addition, on December 28, 2017, Jefferies entered into an agreement with Prudential under which it received $3.25 million as consideration for the release of Prudential by Jefferies from their indemnity relating to the German Pension Plan defined benefit pension obligations.

The provisions and assumptions used in the German pension plan are based on local conditions in Germany. Jefferies did not contribute to the plan during the year ended December 31, 2017.

The following tables summarize the changes in the projected benefit obligation and the components of net periodic pension cost for the years ended December 31, 2017, 2016 and 2015 (in thousands):

to, (1) reduction of the U.S. federal corporate tax rate from 35% to 21%; (2) elimination of the corporate alternative minimum tax; (3) the introduction of the base erosion anti-abuse tax, a new minimum tax; (4) a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries; (5) a new provision designed to tax global intangible low-taxed income; (6) a new limitation on deductible interest expense; (7) the repeal of the domestic production activity deduction; (8) limitations on the deductibility of certain executive compensation; (9) limitations on the use of foreign tax credits to reduce U.S. income tax liability; (10) limitations on NOLs generated after December 31, 2017, to 80% of taxable income; (11) requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over 8 years; and (12) bonus depreciation that will allow for full expensing of qualified property.

On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740, Income Taxes. SAB 118 provides a three-step process to be applied at each reporting period to account for and qualitatively disclose: (1) the effects of the change in tax law for which accounting is complete; (2) provisional amounts (or adjustments to provisional amounts) for the effects of the tax law where accounting is not complete, but that a reasonable estimate has been determined: and (3) where a reasonable estimate cannot yet be made and therefore taxes are reflected in accordance with the law prior to the enactment of the Tax Act.

Due to the complex nature of the Tax Act, we have not completed our accounting for the income tax effects of certain elements of the Tax Act. If we were able to make reasonable estimates of the effects of certain elements for which our analysis is not yet complete, we recorded a provisional estimate in the financial statements. If we were not yet able to make reasonable estimates of the impact of certain elements, we have not recorded any adjustments related to those elements and have continued accounting for them in accordance with ASC 740 on the basis of the tax laws in effect before the Tax Act. The ultimate impact of the Tax Act may differ from this estimate, possibly materially, due to changes in interpretations and assumptions, and guidance that may be issued and actions we may take in response to the Tax Act. We note that the Tax Act is complex and we continue to assess the impact that various provisions will have on our business.

Since the Tax Act was passed late in the fourth quarter of 2017, and ongoing guidance and accounting interpretation are expected over the next 12 months, we consider the accounting for the deferred tax asset remeasurements, the transition tax, and other items to be incomplete due to the forthcoming guidance and our ongoing analysis of final year-end data and tax positions. In connection with our initial analysis, we have recorded a discrete tax expense of $450.5 million as a provisional estimate of the impact of the Tax Act, including the portion related to Jefferies, during 2017 increasing our effective tax rate by 44.4% to 75.1%. This provisional estimate primarily consists of a $415.0 million expense related to the revaluation of our deferred tax asset and a $35.5 million expense related to the deemed repatriation of foreign earnings. Additionally, for the year ended December 31, 2017, our provision for income taxes was reduced by a $31.9 million benefit resulting from the repatriation of Jefferies earnings from certain of its foreign subsidiaries, along with their associated foreign tax credits.

For the year ended December 31, 2016, our provision for income taxes included a $24.9 million charge related to previously issued stock awards. The majority of the awards expired during the first quarter of 2016. The tax deductions associated with the remainder of the awards was less than the compensation cost recognized for financial reporting purposes. For the year ended December 31, 2015, we recorded a benefit related to certain state and local net operating loss carryforwards which we believe are more likely than not to be realized in the future, a significant portion of which resulted from enacted state and local tax law changes.

The following table presents the U.S. and non-U.S. components of income from continuing operations before income taxes for each of the three years in the period ended December 31, 2017 (in thousands):

	2017		2016			2015
U.S.	$	944,014	$	337,374		$	336,856

Income from continuing operations before income taxes	$	1,013,814	$	316,430		$	356,536

(1) For purposes of this table, non-U.S. income is defined as income generated from operations located outside the U.S.

F-75

For each of the three years in the period ended December 31, 2017, income tax expense differed from the amounts computed by applying the U.S. Federal statutory income tax rate of 35% to income from continuing operations before income taxes as a result of the following (dollars in thousands):

	2017					2016					2015
	Amount			Percent		Amount			Percent		Amount			Percent
Computed expected federal income tax	$	354,835		35.0	%	$	110,751		35.0	%	$	124,788		35.0	%

The following table presents a reconciliation of gross unrecognized tax benefits for each of the three years in the period ended December 31, 2017 (in thousands):

	2017			2016			2015
Balance at beginning of period	$	148,848		$	150,867		$	148,590
Increases based on tax positions related to the current period	18,619			5,045			3,475
Increases based on tax positions related to prior periods	10,358			3,697			22,030
Decreases based on tax positions related to prior periods	(8,805		)	(9,414		)	(15,349		)
Decreases related to settlements with taxing authorities	—			(1,347		)	(7,879		)
Balance at end of period	$	169,020		$	148,848		$	150,867

Net interest expense related to unrecognized tax benefits was $9.7 million, $8.6 million and $4.2 millionfor the years ended December 31, 2017, 2016 and 2015, respectively. At December 31, 2017 and 2016, we had interest accrued of approximately $57.4 million and $47.7 million, respectively, included in Payables, expense accruals and other liabilities in the Consolidated Statements of Financial Condition. No material penalties were accrued for the years ended December 31, 2017 and 2016.

The statute of limitations with respect to our federal income tax returns has expired for all years through 2012. Our 2013 federal tax return is currently under examination by the Internal Revenue Service. Our New York State and New York City income tax returns are currently being audited for the 2012 to 2014 period and 2011 to 2012 period, respectively. Prior to becoming a wholly-owned subsidiary, Jefferies filed a consolidated U.S. federal income tax return with its qualifying subsidiaries and was subject to income tax in various states, municipalities and foreign jurisdictions. Jefferies is currently under examination by the Internal Revenue Service and other major tax jurisdictions. The statute of limitations with respect to Jefferies federal income tax returns has expired for all years through 2012.

F-76

We do not expect that resolution of these examinations will have a significant effect on our consolidated financial position, but could have a significant impact on the consolidated results of operations for the period in which resolution occurs. Over the next twelve months, we believe it is reasonably possible that various tax examinations will be concluded and statutes of limitation will expire which would have the effect of reducing the balance of unrecognized tax benefits by $14.0 million. If recognized, the total amount of unrecognized tax benefits reflected in the table above would lower our effective income tax rate.

The principal components of deferred taxes at December 31, 2017 and 2016 are as follows (in thousands):

	2017			2016

As of December 31, 2017, we have consolidated U.S. federal NOLs of $1.2 billion that may be used to offset the taxable income of any member of our consolidated tax group. In addition, we have $1.2 billion of U.S. federal NOLs that are only available to offset the taxable income of certain subsidiaries. Federal NOLs begin to expire in 2023, with a substantial amount expiring between 2023 and 2025. We have various state NOLs that expire at different times, which are reflected in the above table to the extent our estimate of future taxable income will be apportioned to those states. We have gross foreign net operating loss carryforwards of approximately $68.6 million. There is a valuation allowance with respect to $10.0 million of these foreign net operating loss carryforwards. Uncertainties that may affect the utilization of our tax attributes include future operating results, tax law changes, rulings by taxing authorities regarding whether certain transactions are taxable or deductible and expiration of carryforward periods.

Under certain circumstances, the ability to use the NOLs and future deductions could be substantially reduced if certain changes in ownership were to occur. In order to reduce this possibility, our certificate of incorporation includes a charter restriction that prohibits transfers of our common stock under certain circumstances.

We are currently evaluating the impact of the Tax Act on our indefinite reinvestment assertion. At December 31, 2016, we had approximately $157.0 million of earnings attributable to foreign subsidiaries that were indefinitely reinvested abroad and for which no U.S. federal income tax provision had been recorded. Accordingly, deferred tax liabilities of approximately $55.0 million had not been recorded with respect to these earnings at December 31, 2016.

(1) Represents dividends declared during the period on participating securities plus an allocation of undistributed earnings to participating securities. Net losses are not allocated to participating securities. Participating securities represent restricted stock and RSUs for which requisite service has not yet been rendered and amounted to weighted-average shares of 1,401,000, 1,986,800 and 6,500,000for the years ended December 31, 2017, 2016 and 2015, respectively. Dividends declared on participating securities during the years ended December 31, 2017, 2016 and 2015 were $0.4 million, $0.4 million and $1.5 million, respectively. Undistributed earnings are allocated to participating securities based upon their right to share in earnings if all earnings for the period had been distributed.

Options to purchase 656,894 and 1,000,137 weighted-average shares of common stock were outstanding during the years ended December 31, 2016 and 2015, respectively, but were not included in the computation of diluted per share amounts as the effect was antidilutive. Amounts for 2017 were not material.

For the years ended December 31, 2016 and 2015, weighted-average common shares of 923,077 and 4,000,000, respectively, related to outstanding warrants to purchase common shares at $33.33 per share, were not included in the computation of diluted per share amounts as the effect was antidilutive. The warrants expired in the first quarter of 2016.

For the years ended December 31, 2017, 2016 and 2015, shares related to the 3.875% Convertible Senior Debentures were not included in the computation of diluted per share amounts as the conversion price exceeded the average market price. For the years ended December 31, 2017, 2016 and 2015, 4,162,200 shares related to the mandatorily redeemable convertible preferred shares were not included in the computation of diluted per share amounts as the effect was antidilutive.

(2) At December 31, 2017, $3,207.4 million within forward starting securities purchased under agreements to resell and $2,982.8 million within securities sold under agreements to repurchase settled within three business days.

Equity Commitments.  Equity commitments include commitments to invest in Jefferies joint venture, Jefferies Finance, and commitments to invest in private equity funds and in Jefferies Capital Partners, LLC, the manager of the private equity funds, which are managed by a team led by Brian P. Friedman, our President and a Director. As of December 31, 2017, Jefferies outstanding commitments relating to Jefferies Capital Partners, LLC and its private equity funds was $22.0 million.

See Note 10 for additional information regarding Jefferies investment in Jefferies Finance.

F-80

Our equity commitments also include our commitment to invest in 54 Madison, a fund which targets real estate projects. We plan to invest a cumulative total of $202.5 million to this fund, of which we have already contributed $144.8 million. Capital commitments are contingent upon approval of the related investment by the investment committee, of which we have two of the four seats. Through December 31, 2017, approved unfunded commitments totaled $28.0 million.

Additionally, as of December 31, 2017, we have other equity commitments to invest up to $14.4 million in various other investments.

Loan Commitments. From time to time Jefferies makes commitments to extend credit to investment banking and other clients in loan syndication, acquisition finance and securities transactions and to SPE sponsors in connection with the funding of CLO and other asset-backed transactions. These commitments and any related drawdowns of these facilities typically have fixed maturity dates and are contingent on certain representations, warranties and contractual conditions applicable to the borrower. As of December 31, 2017, Jefferies has $68.3 million of outstanding loan commitments to clients.

Loan commitments outstanding as of December 31, 2017, also include Jefferies portion of the outstanding secured revolving credit facility provided to Jefferies Finance to support loan underwritings by Jefferies Finance. At December 31, 2017, none of Jefferies $250.0 million commitment was funded.

In August 2014, we and Solomon Kumin established Folger Hill; we committed to provide Folger Hill with a three-year, $20.0 million revolving credit facility to fund its start-up and initial operating expenses. During the third quarter of 2017, the facility was amended to extend the maturity date until December 31, 2018 and to provide for an optional termination right for the Company with ten days prior written notice. As of December 31, 2017, $10.2 million has been provided to Folger Hill under the revolving credit facility.

Mortgage-Related and Other Purchase Commitments.  Jefferies enters into forward contracts to purchase mortgage participation certificates, mortgage-backed securities and consumer loans. The mortgage participation certificates evidence interests in mortgage loans insured by the Federal Housing Administration and the mortgage-backed securities are insured or guaranteed by Fannie Mae, Freddie Mac or Ginnie Mae. Jefferies frequently securitizes the mortgage participation certificates and mortgage-backed securities. The fair value of mortgage-related and other purchase commitments recorded in the Consolidated Statement of Financial Condition at December 31, 2017 was $37.6 million.

Underwriting Commitments. In connection with investment banking activities, Jefferies may from time to time provide underwriting commitments to its clients in connection with capital raising transactions.

Forward Starting Reverse Repos and Repos.  Jefferies enters into commitments to take possession of securities with agreements to resell on a forward starting basis and to sell securities with agreements to repurchase on a forward starting basis that are primarily secured by U.S. government and agency securities.

Other Unfunded Commitments.  Other unfunded commitments include obligations in the form of revolving notes to provide financing to asset-backed and CLO vehicles. Upon advancing funds, drawn amounts are collateralized by the assets of an entity.

Contingencies

We and our subsidiaries are parties to legal and regulatory proceedings that are considered to be either ordinary, routine litigation incidental to their business or not significant to our consolidated financial position. We and our subsidiaries are also involved, from time to time, in other exams, investigations and similar reviews (both formal and informal) by governmental and self-regulatory agencies regarding our businesses, certain of which may result in judgments, settlements, fines, penalties or other injunctions. We do not believe that any of these actions will have a significant adverse effect on our consolidated financial position or liquidity, but any amounts paid could be significant to results of operations for the period.

Guarantees

Derivative Contracts.  Jefferies dealer activities cause it to make markets and trade in a variety of derivative instruments. Certain derivative contracts that Jefferies has entered into meet the accounting definition of a guarantee under GAAP, including credit default swaps, written foreign currency options and written equity put options. On certain of these contracts, such as written interest rate caps and foreign currency options, the maximum payout cannot be quantified since the increase in interest or foreign exchange rates are not contractually limited by the terms of the contract. As such, we have disclosed notional values as a measure of Jefferies maximum potential payout under these contracts.

F-81

The following table summarizes the notional amounts associated with our derivative contracts meeting the definition of a guarantee under GAAP as of December 31, 2017 (in millions):

	Expected Maturity Date
Guarantee Type	2018		2019		2020 and 2021		2022 and 2023		2024 and Later		Notional/ Maximum Payout
Derivative contracts – non-credit related	$	24,454.8	$	2,420.2	$	150.5	$	45.9	$	466.3	$	27,537.7
Written derivative contracts – credit related	—		42.0		20.5		155.7		—		218.2
Total derivative contracts	$	24,454.8	$	2,462.2	$	171.0	$	201.6	$	466.3	$	27,755.9

The derivative contracts deemed to meet the definition of a guarantee under GAAP are before consideration of hedging transactions and only reflect a partial or "one-sided" component of any risk exposure. Written equity options and written credit default swaps are often executed in a strategy that is in tandem with long cash instruments (e.g., equity and debt securities). Jefferies substantially mitigates its exposure to market risk on these contracts through hedges, such as other derivative contracts and/or cash instruments and Jefferies manages the risk associated with these contracts in the context of its overall risk management framework. Jefferies believes notional amounts overstate its expected payout and that fair value of these contracts is a more relevant measure of its obligations. The fair value of derivative contracts meeting the definition of a guarantee is approximately $243.6 million as of December 31, 2017.

Berkadia.  We have agreed to reimburse Berkshire Hathaway for up to one-half of any losses incurred under a $1.5 billion surety policy securing outstanding commercial paper issued by an affiliate of Berkadia. As of December 31, 2017, the aggregate amount of commercial paper outstanding was $1.47 billion.

Other Guarantees.  Jefferies is a member of various exchanges and clearing houses. In the normal course of business Jefferies provides guarantees to securities clearinghouses and exchanges. These guarantees generally are required under the standard membership agreements, such that members are required to guarantee the performance of other members. Additionally, if a member becomes unable to satisfy its obligations to the clearinghouse, other members would be required to meet these shortfalls. To mitigate these performance risks, the exchanges and clearinghouses often require members to post collateral. Jefferies obligations under such guarantees could exceed the collateral amounts posted. Jefferies maximum potential liability under these arrangements cannot be quantified; however, the potential for Jefferies to be required to make payments under such guarantees is deemed remote.  Accordingly, no liability has been recognized for these arrangements.

Indemnification.  In connection with the 2013 sale of Empire Insurance Company, we agreed to indemnify the buyer for certain of Empire’s lease obligations that were assumed by another subsidiary of ours as part of the sale of Empire. Our subsidiary was subsequently sold in 2014 to HomeFed as part of the real estate transaction with HomeFed. Although HomeFed has agreed to indemnify us for these lease obligations, our indemnification obligation under the Empire transaction remains. The primary lease expires in 2018 and the aggregate amount of lease obligation as of December 31, 2017 was approximately $9.8 million. Substantially all of the space under the primary lease has been sublet to various third-party tenants for the full length of the lease term in amounts in excess of the obligations under the primary lease.

Standby Letters of Credit.  At December 31, 2017, Jefferies provided guarantees to certain counterparties in the form of standby letters of credit in the amount of $51.8 million. Standby letters of credit commit Jefferies to make payment to the beneficiary if the guaranteed party fails to fulfill its obligation under a contractual arrangement with that beneficiary. Since commitments associated with these collateral instruments may expire unused, the amount shown does not necessarily reflect the actual future cash funding requirement. Other subsidiaries of ours have outstanding letters of credit aggregating $15.0 million at December 31, 2017. Primarily all letters of credit expire within one year.

Note 25.  Net Capital Requirements

Jefferies operates as a broker-dealer registered with the SEC and member firms of the Financial Industry Regulatory Authority ("FINRA"). Jefferies LLC is subject to the Securities and Exchange Commission Uniform Net Capital Rule ("Rule 15c3-1"), which requires the maintenance of minimum net capital and has elected to calculate minimum capital requirements using the alternative method permitted by Rule 15c3-1 in calculating net capital. Jefferies LLC, as a dully-registered U.S. broker-dealer and futures commission merchant ("FCM"), is also subject to Rule 1.17 of the CFTC which sets forth minimum financial requirements. The minimum net capital requirement in determining excess net capital for a dually-registered U.S. broker-dealer and FCM is equal to the greater of the requirement under Rule 15c3-1 or CFTC Rule 1.17. In November 2017, Jefferies Execution Services, Inc. merged with and into Jefferies LLC, with Jefferies LLC as the surviving entity.

Jefferies LLC’s net capital and excess net capital as of December 31, 2017 were $1,418.9 million and $1,330.2 million, respectively.

FINRA is the designated examining authority for Jefferies U.S. broker-dealer and the NFA is the designated self-regulatory organization for Jefferies LLC as an FCM.

Certain other U.S. and non-U.S. subsidiaries of Jefferies are subject to capital adequacy requirements as prescribed by the regulatory authorities in their respective jurisdictions, including Jefferies International Limited which is authorized and regulated by the Financial Conduct Authority in the United Kingdom.

The regulatory capital requirements referred to above may restrict our ability to withdraw capital from Jefferies regulated subsidiaries. Some of our other consolidated subsidiaries also have credit agreements which may restrict the payment of cash dividends, or the ability to make loans or advances to the parent company.

Note 26.  Other Fair Value Information

The carrying amounts and estimated fair values of our principal financial instruments that are not recognized at fair value on a recurring basis are as follows (in thousands):

(1) Notes and loans receivable:  The fair values are estimated principally based on a discounted future cash flows model using market interest rates for similar instruments. If measured at fair value in the financial statements, these financial instruments would be classified as Level 3 in the fair value hierarchy.

(2) Short-term borrowings:  The fair values of short-term borrowings are estimated to be the carrying amount due to their short maturities. If measured at fair value in the financial statements, these financial instruments would be classified as Level 3 in the fair value hierarchy.

(3) Long-term debt: The fair values are estimated using quoted prices, pricing information obtained from external data providers and, for certain variable rate debt, is estimated to be the carrying amount. If measured at fair value in the financial statements, these financial instruments would be classified as Level 2 and Level 3 in the fair value hierarchy.

LEUCADIA NATIONAL CORPORATION

(PARENT COMPANY ONLY)

Notes to Condensed Financial Statements

1. Introduction and Basis of Presentation

The notes to the consolidated financial statements of Leucadia National Corporation and Subsidiaries (the "Company") are incorporated by reference into this schedule. For purposes of these condensed non-consolidated financial statements, the Company's wholly-owned and majority owned subsidiaries are accounted for using the equity method of accounting ("equity method subsidiaries").

The Parent Company Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (" GAAP"). The significant accounting policies of the Parent Company Financial Statements are those used by the Company on a consolidated basis, to the extent applicable. For further information regarding the significant accounting policies refer to Note 2, Significant Accounting Policies, in the Company's consolidated financial statements included in the 2017 10-K.

The Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these financial statements in conformity with GAAP. The most important of these estimates and assumptions relate to fair value measurements, goodwill and intangible assets, the ability to realize deferred tax assets and the recognition and measurement of uncertain tax positions. Although these and other estimates and assumptions are based on the best available information, actual results could be materially different from these estimates.

2. Cash Flows

Supplemental cash flow information related to the Parent Company for the years ended December 31, 2017, 2016 and 2015 is as follows (in thousands):

	2017		2016			2015
Cash paid during the year for:
Interest	$	57,813	$	57,813		$	95,074
Income tax payments (refunds), net	$	1,440	$	(10,199	)	$	(2,332	)
Non-cash investing activities:
Investments contributed to subsidiary	$	25,328	$	423,009		$	—
Investments transferred from subsidiary	$	—	$	2,022		$	—
Dividends received from subsidiaries	$	32,792	$	—		$	—

3. Transactions with Subsidiaries

The Parent Company has transactions with its equity method subsidiaries, many of which are structured as interest bearing advances to/from its subsidiaries. Intercompany interest expense primarily reflects the interest on funding advances incurred by the Parent to its wholly-owned subsidiary which holds assets related to its treasury function. Interest is incurred on funding advances based on the prime rate plus .125%. Although there is frequent cash movement between these subsidiaries and the Parent, they do not represent cash dividends. As such, the Parent Company received no cash dividends from its subsidiaries during the three years ended December 31, 2017.

Historically, excess cash was provided to the Parent Company by its subsidiaries in the form of loans rather than as distributions. Through a series of steps, the Parent Company is reducing these intercompany loans to zero. From January 1, 2018 through February 15, 2018, the Parent Company received non-cash dividends totaling $7.9 billion from its subsidiaries. Of this amount, $7.9 billion will be reflected as a decrease in our Investment in subsidiaries, $0.2 billion will be reflected as a decrease to Advances to subsidiaries and $8.1 billion will be reflected as a decrease to Advances from subsidiaries.

4. Commitments, Contingencies and Guarantees

In the normal course of its business, the Parent Company has various commitments, contingencies and guarantees as described in Note 24, Commitments, Contingencies and Guarantees, and Note 16, Mezzanine Equity, in the Company's consolidated financial statements.

S-5

5. Restricted Net Assets

For a discussion of the Company's regulatory requirements, see Note 25, Net Capital Requirements, in the Company's consolidated financial statements. Some of the Company's consolidated subsidiaries also have credit agreements which may restrict the payment of cash dividends, or the ability to make loans or advances to the Parent Company.

At December 31, 2017 and 2016, $6.1 billion and $6.0 billion, respectively, of net assets of the Parent Company's consolidated subsidiaries are restricted as to the payment of cash dividends, or the ability to make loans or advances to the Parent Company. At December 31, 2017 and 2016, $5.1 billion and $4.8 billion, respectively, of these net assets are restricted as they reflect regulatory capital requirements or require regulatory approval prior to the payment of cash dividends and advances to the Parent Company.

Included in retained earnings of the Parent Company at December 31, 2017 are $202.9 million of undistributed earnings of unconsolidated associated companies. For further information, see Note 10, Loans to and Investments in Associated Companies, in the Company's consolidated financial statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Nature of Operations

Nature of Operations

Leucadia National Corporation (“Leucadia” or the “Company”) is a diversified holding company focused on long-term value creation to maximize shareholder value. We continuously review acquisitions of businesses, securities and assets that have the potential for significant long-term value creation, invest in a broad array of businesses, and evaluate the retention and disposition of our existing operations and holdings. Changes in the mix of our businesses and investments should be expected.

Our financial services businesses and investments include Jefferies (investment banking and capital markets), Leucadia Asset Management (asset management), Berkadia (commercial mortgage banking, investment sales and servicing), HomeFed (real estate company), FXCM (provider of online foreign exchange trading services) and Foursight Capital (vehicle finance). We also own and have investments in a diverse array of other businesses, including National Beef (beef processing), HRG Group ("HRG") (consumer products), Garcadia (automobile dealerships), Linkem (fixed wireless broadband services in Italy), Vitesse Energy and JETX Energy (oil and gas production and development), Idaho Timber (manufacturing) and Golden Queen (gold and silver mining). The structure of each of our investments was tailored to the unique opportunity each transaction presented. Our investments may be reflected in our consolidated results as consolidated subsidiaries, equity investments, securities or in other ways, depending on the structure of our specific holdings.

Jefferies is the largest independent U.S. headquartered global full-service, integrated securities and investment banking firm. In March 2013, Jefferies became an indirect wholly-owned subsidiary of Leucadia, yet retains a separate credit rating and continues to be a separate SEC reporting company.  Through Jefferies, we own 50% of Jefferies Finance LLC ("Jefferies Finance"), our joint venture with Massachusetts Mutual Life Insurance Company.  Jefferies Finance is a commercial finance company whose primary focus is the origination and syndication of senior secured debt of middle market and growth companies in the form of term and revolving loans. Through Jefferies, we also owned a 48.5% voting interest in Jefferies LoanCore, LLC ("Jefferies LoanCore"), a joint venture with the Government of Singapore Investment Corporation, the Canadian Pension Plan Investment Board and LoanCore, LLC. Jefferies LoanCore originates, purchases and securitizes commercial real estate loans throughout the U.S. On October 31, 2017, Jefferies sold all of its membership interests in Jefferies LoanCore for approximately $173.1 million, the estimated book value as of October 31, 2017. In addition, Jefferies may be entitled to additional cash consideration over the next five years in the event Jefferies LoanCore's yearly return on equity exceeds certain thresholds.

Jefferies has a November 30^th year-end, which it retains for standalone reporting purposes. We reflect Jefferies in our consolidated financial statements utilizing a one month lag. We have reviewed Jefferies business and internal operating results for the month of December 2017 for the purpose of evaluating whether financial statement disclosures or adjustments are required in this Annual Report on Form 10-K, and we have concluded that, other than the effects of the Tax Cuts and Jobs Act of 2017 (the "Tax Act"), no additional disclosures or adjustments are warranted. See Note 20 to our consolidated financial statements for additional information.

Leucadia Asset Management ("LAM") supports and develops focused alternative asset management businesses led by distinct management teams. These include Folger Hill Asset Management LLC ("Folger Hill"), a multi-manager discretionary long/short equity hedge fund platform; Topwater Capital, a first-loss product; CoreCommodity Management LLC, an asset manager that focuses on commodities strategies; Tenacis Capital, a systematic macro investment platform; Lake Hill, an electronic trader in listed options and futures across asset classes; as well as several other smaller businesses. In addition, several investment management businesses, including Jefferies Strategic Investments Division, operate under Jefferies and are included under our marketing of the LAM platform.

Berkadia Commercial Mortgage LLC ("Berkadia"), our 50-50 equity method joint venture with Berkshire Hathaway Inc., provides capital solutions, investment sales advisory and mortgage servicing for multifamily and commercial properties.

We own an approximate 70% equity method interest of HomeFed, which owns and develops residential and mixed use real estate properties. We have contractually agreed to limit our voting rights to 45% of HomeFed's total voting securities voting on any matter. HomeFed is a public company traded on the NASD OTC Bulletin Board.

Our investment in FXCM Group, LLC ("FXCM") and associated companies consist of a senior secured term loan due January 2019, ($69.9 million principal outstanding at December 31, 2017); a 50% voting interest in FXCM and up to 75% of all distributions. FXCM's six-member board is comprised of three directors appointed by Leucadia and three directors appointed by Global Brokerage Holdings, LLC ("Global Brokerage Holdings"). See Notes 4 and 10 to our consolidated financial statements for additional information.

We own 100% of Foursight Capital, an auto loan originator and servicer, and 85% of Chrome Capital, which owns and manages a portfolio of leases on used Harley-Davidson motorcycles and is in the process of winding down.

We own 78.9% of National Beef Packing Company. National Beef processes and markets fresh and chilled boxed beef, ground beef, beef by-products, consumer-ready beef and pork, and wet blue leather for domestic and international markets. National Beef operates two beef processing facilities, three consumer-ready processing facilities and a wet blue tanning facility, all located in the U.S. National Beef operates one of the largest wet blue tanning facilities in the world that sells processed hides to tanners that produce finished leather for the automotive, luxury goods, apparel and furniture industries. National Beef owns Kansas City Steak Company, LLC, which sells portioned beef and other products directly to customers through the internet, direct mail and direct response television. National Beef also owns a refrigerated and livestock transportation and logistics company that provides transportation services for National Beef and third parties.

We own approximately 23% of HRG Group, Inc. ("HRG"), a publicly traded company (NYSE: HRG), and we reflect this investment at fair value based on quoted market prices. HRG primarily owns approximately 59% of Spectrum Brands, a publicly traded (NYSE: SPB) global consumer products company. HRG sold its approximate 80% interest in Fidelity & Guaranty Life, a life insurance and annuity products company and 100% interest in Front Street, a long-term reinsurance company to CF Corporation in the fourth quarter of 2017.

Garcadia is an equity method joint venture that owns and operates 28 automobile dealerships in California, Texas, Iowa and Michigan. We own approximately 75% of Garcadia and have board representation and votes equal to the other member of the joint venture.

We own approximately 42% of the common shares of Linkem, as well as convertible preferred shares which, if converted, would increase our ownership to approximately 53% of Linkem's common equity at December 31, 2017. Linkem provides residential broadband services using LTE technologies deployed over the 3.5 GHz spectrum band. Linkem operates in Italy, which has few cable television systems and poor broadband alternatives. Linkem is accounted for under the equity method.

Vitesse Energy, LLC ("Vitesse") is our 96% owned consolidated subsidiary that acquires and develops non-operated working and royalty oil and gas interests in the Bakken Shale oil field in North Dakota and Montana as well as the Denver-Julesburg Basin in Wyoming.

Significant Accounting Policies

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

The preparation of these financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) requires us to make estimates and assumptions that affect the reported amounts in the financial statements and disclosures of contingent assets and liabilities. On an on-going basis, we evaluate all of these estimates and assumptions. The most important of these estimates and assumptions relate to fair value measurements, compensation and benefits, asset impairment, the ability to realize deferred tax assets, the recognition and measurement of uncertain tax positions and contingencies. Although these and other estimates and assumptions are based on the best available information, actual results could be different from these estimates.

Consolidation

Our policy is to consolidate all entities in which we can vote a majority of the outstanding voting stock. In addition, we consolidate entities which meet the definition of a variable interest entity for which we are the primary beneficiary. The primary beneficiary is the party who has the power to direct the activities of a variable interest entity that most significantly impact the entity’s economic performance and who has an obligation to absorb losses of the entity or a right to receive benefits from the entity that could potentially be significant to the entity. We consider special allocations of cash flows and preferences, if any, to determine amounts allocable to noncontrolling interests. All intercompany transactions and balances are eliminated in consolidation.

In situations where we have significant influence, but not control, of an entity that does not qualify as a variable interest entity, we apply either the equity method of accounting or fair value accounting pursuant to the fair value option election under GAAP.  We have also formed nonconsolidated investment vehicles with third-party investors that are typically organized as partnerships or limited liability companies. Our subsidiaries may act as general partner or managing member for these investment vehicles and have generally provided the third-party investors with termination or “kick-out” rights.

Revenue Recognition Policies

Beef Processing and Other Operations

Revenues are recognized when the following conditions are met: (1) collectibility is reasonably assured; (2) title to the product has passed or the service has been rendered and earned; (3) persuasive evidence of an arrangement exists; and (4) there is a fixed or determinable price. National Beef’s revenues are recognized based on the terms of the sale, which for beef processing operations is typically upon delivery to customers. Manufacturing revenues are recognized when title passes.

Investment Banking Activities

Commissions and Other Fees. All customer securities transactions are reported in the Consolidated Statements of Financial Condition on a settlement date basis with related income reported on a trade date basis. We permit institutional customers to allocate a portion of their gross commissions to pay for research products and other services provided by third parties. The amounts allocated for those purposes are commonly referred to as soft dollar arrangements. These arrangements are accounted for on an accrual basis and, as we are not the primary obligor for these arrangements, netted against commission revenues in the Consolidated Statements of Operations. In addition, we earn asset-based fees associated with the management and supervision of assets, account services and administration related to customer accounts.

Principal Transactions. Trading assets and trading liabilities (all of which are recorded on a trade-date basis) are carried at fair value with gains and losses reflected in Principal transaction revenues in the Consolidated Statements of Operations, except for derivatives accounted for as hedges (see Hedge Accounting section, herein and Note 5). Fees received on loans carried at fair value are also recorded within Principal transaction revenues.

Investment Banking.  Underwriting revenues and fees from mergers and acquisitions, restructuring and other investment banking advisory assignments or engagements are recorded when the services related to the underlying transactions are completed under the terms of the assignment or engagement. Expenses associated with such assignments are deferred until reimbursed by the client, the related revenue is recognized or the engagement is otherwise concluded. Expenses are recorded net of client reimbursements and netted against revenues. Unreimbursed expenses with no related revenues are included in Selling, general and administrative expenses in the Consolidated Statements of Operations.

Interest Revenue and Expense.  Interest expense that is deducted from Revenues to arrive at Net revenues is related to Jefferies operations. Contractual interest on Trading assets and Trading liabilities is recognized on an accrual basis as a component of Interest income and Interest expense. Interest flows on derivative trading transactions and dividends are included as part of the fair valuation of these contracts and recognized in Principal transactions in the Consolidated Statements of Operations rather than as a component of interest income or expense. Interest on short- and long-term borrowings is recorded on an accrual basis, except for those for which we have elected the fair value option, as Interest expense. Discounts/premiums arising on long-term debt are accreted/amortized to Interest expense using the effective yield method over the remaining lives of the underlying debt obligations. Interest revenue related to Securities borrowed and Securities purchased under agreements to resell activities and interest expense related to Securities loaned and Securities sold under agreements to repurchase activities are recognized on an accrual basis.

Hedge Accounting

Jefferies applies hedge accounting using interest rate swaps designated as fair value hedges of changes in the benchmark interest rate of fixed rate senior long-term debt. Jefferies interest rate swaps are included as derivative contracts in Trading assets and Trading liabilities in the Consolidated Statements of Financial Condition. Jefferies uses regression analysis to perform ongoing prospective and retrospective assessments of the effectiveness of these hedging relationships. A hedging relationship is deemed effective if the change in fair value of the interest rate swap and the change in the fair value of the long-term debt due to changes in the benchmark interest rate offset within a range of 80% to 125%. The impact of valuation adjustments related to Jefferies own credit spreads and counterparty credit spreads are included in the assessment of effectiveness.

For qualifying fair value hedges of benchmark interest rates, the change in the fair value of the derivative and the change in fair value of the long-term debt provide offset of one another, and together with any resulting ineffectiveness, are recorded in Interest expense. See Note 5 for further information.

Cash Equivalents

Cash equivalents include highly liquid investments, including money market funds and certificates of deposit, not held for resale with original maturities of three months or less.

Cash and Securities Segregated and on Deposit for Regulatory Purposes or Deposited With Clearing and Depository Organizations

In accordance with Rule 15c3-3 of the Securities Exchange Act of 1934, Jefferies LLC, as a broker-dealer carrying client accounts, is subject to requirements related to maintaining cash or qualified securities in a segregated reserve account for the exclusive benefit of its clients. Certain other entities are also obligated by rules mandated by their primary regulators to segregate or set aside cash or equivalent securities to satisfy regulations, promulgated to protect customer assets. In addition, certain exchange and/or clearing organizations require cash and/or securities to be deposited by us to conduct day to day activities.

Financial Instruments and Fair Value

Trading assets and Trading liabilities are recorded at fair value, either as required by accounting pronouncements or through the fair value option election. Gains and losses on trading assets and trading liabilities are recognized in our Consolidated Statements of Operations in Principal transactions. Available for sale securities are reflected at fair value, with unrealized gains and losses reflected as a separate component of equity, net of taxes. When sold, realized gains and losses on available for sale securities are reflected in the caption Net realized securities gains. The cost of securities sold is based on average cost. Fair value is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price).

Fair Value Hierarchy

In determining fair value, we maximize the use of observable inputs and minimize the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from independent sources. Unobservable inputs reflect our assumptions that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. We apply a hierarchy to categorize our fair value measurements broken down into three levels based on the transparency of inputs as follows:

Level 1: Quoted prices are available in active markets for identical assets or liabilities as of the reported date. Valuation adjustments and block discounts are not applied to Level 1 instruments.

Level 2: Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these financial instruments includes cash instruments for which quoted prices are available but traded less frequently, derivative instruments fair values for which have been derived using model inputs that are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed.

Level 3: Instruments that have little to no pricing observability as of the reported date. These financial instruments are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation.

Financial instruments are valued at quoted market prices, if available. Certain financial instruments have bid and ask prices that can be observed in the marketplace. For financial instruments whose inputs are based on bid-ask prices, the financial instrument is valued at the point within the bid-ask range that meets our best estimate of fair value. We use prices and inputs that are current as of the measurement date. For financial instruments that do not have readily determinable fair values using quoted market prices, the determination of fair value is based upon consideration of available information, including types of financial instruments, current financial information, restrictions on dispositions, fair values of underlying financial instruments and quotations for similar instruments.

The valuation of financial instruments may include the use of valuation models and other techniques. Adjustments to valuations derived from valuation models may be made when, in management’s judgment, features of the financial instrument such as its complexity, the market in which the financial instrument is traded and risk uncertainties about market conditions require that an adjustment be made to the value derived from the models. Adjustments from the price derived from a valuation model reflect management’s judgment that other participants in the market for the financial instrument being measured at fair value would also consider in valuing that same financial instrument. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment.

The availability of observable inputs can vary and is affected by a wide variety of factors, including, for example, the type of financial instrument and market conditions. As the observability of prices and inputs may change for a financial instrument from period to period, this condition may cause a transfer of an instrument among the fair value hierarchy levels. Transfers among the levels are recognized at the beginning of each period. The degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.

Valuation Process for Financial Instruments

The Jefferies Independent Price Verification ("IPV") Group, which is part of the Jefferies finance department, in partnership with Jefferies Risk Management, is responsible for establishing Jefferies valuation policies and procedures. The IPV Group and Risk Management, which are independent of business functions, play an important role and serve as a control function in determining that Jefferies financial instruments are appropriately reflected at fair value. This is particularly important where prices or valuations that require inputs are less observable. In the event that observable inputs are not available, the control processes are designed to assure that the valuation approach utilized is appropriate and consistently applied and that the assumptions are reasonable. The IPV Group reports to the Jefferies Global Controller and is subject to the oversight of the IPV Committee, which includes senior members of Jefferies finance department and other personnel. Jefferies independent price verification policies and procedures are reviewed, at a minimum, annually and changes to the policies require the approval of the IPV Committee.

Price Testing Process.  Jefferies business units are responsible for determining the fair value of Jefferies financial instruments using approved valuation models and methodologies. In order to ensure that the business unit valuations represent a fair value exit price, the IPV Group tests and validates the fair value of the financial instruments inventory. In the testing process, the IPV Group obtains prices and valuation inputs from sources independent of Jefferies, consistently adheres to established procedures set forth in the valuation policies for sourcing prices and valuation inputs and utilizing valuation methodologies. Sources used to validate fair value prices and inputs include, but are not limited to, exchange data, recently executed transactions, pricing data obtained from third party vendors, pricing and valuation services, broker quotes and observed comparable transactions.

To the extent discrepancies between the business unit valuations and the pricing or valuations resulting from the price testing process are identified, such discrepancies are investigated by the IPV Group and fair values are adjusted, as appropriate. The IPV Group maintains documentation of its testing, results, rationale and recommendations and prepares a monthly summary of its valuation results. This process also forms the basis for the classification of fair values within the fair value hierarchy (i.e., Level 1, Level 2 or Level 3). The IPV Group utilizes the additional expertise of Risk Management personnel in valuing more complex financial instruments and financial instruments with less or limited pricing observability. The results of the valuation testing are reported to the IPV Committee on a monthly basis, which discusses the results and determines the financial instrument fair values in the consolidated financial statements. At each quarter end, the overall valuation results, as determined by the IPV Committee, are presented to the Jefferies Audit Committee.

Judgment exercised in determining Level 3 fair value measurements is supplemented by daily analysis of profit and loss performed by the Product Control functions. Gains and losses, which result from changes in fair value, are evaluated and corroborated daily based on an understanding of each trading desk's overall risk positions and developments in a particular market on the given day.  Valuation techniques generally rely on recent transactions of suitably comparable financial instruments and use the observable inputs from those comparable transactions as a validation basis for Level 3 inputs. Level 3 fair value measurements are further validated through subsequent sales testing and market comparable sales, if such information is available. Level 3 fair value measurements require documentation of the valuation rationale applied, which is reviewed for consistency in application from period to period.

Third Party Pricing Information.  Pricing information obtained from external data providers (including independent pricing services and brokers) may incorporate a range of market quotes from dealers, recent market transactions and benchmarking model derived prices to quoted market prices and trade data for comparable securities. External pricing data is subject to evaluation for reasonableness by the IPV Group using a variety of means including comparisons of prices to those of similar product types, quality and maturities, consideration of the narrowness or wideness of the range of prices obtained, knowledge of recent market transactions and an assessment of the similarity in prices to comparable dealer offerings in a recent time period. Jefferies processes challenges the appropriateness of pricing information obtained from external data providers (including independent pricing services and brokers) to validate the data for consistency with the definition of a fair value exit price. Jefferies process includes understanding and evaluating the external data providers’ valuation methodologies. For corporate, U.S. government and agency, municipal debt securities, and loans, to the extent independent pricing services or broker quotes are utilized in Jefferies valuation process, the vendor service providers are collecting and aggregating observable market information as to recent trade activity and active bid-ask submissions. The composite pricing information received from the independent pricing service is thus not based on unobservable inputs or proprietary models. For mortgage- and other asset-backed securities, collateralized debt obligations ("CDOs") and collateralized loan obligations ("CLOs"), the independent pricing services use a matrix evaluation approach incorporating both observable yield curves and market yields on comparable securities as well as implied inputs from observed trades for comparable securities in order to determine prepayment speeds, cumulative default rates and loss severity. Further, Jefferies considers pricing data from multiple service providers as available as well as compares pricing data to prices observed for recent transactions, if any, in order to corroborate valuation inputs.

Model Review Process.  If a pricing model is used to determine fair value, the pricing model is reviewed for theoretical soundness and appropriateness by Risk Management, independent from the trading desks, and then approved by Risk Management to be used in the valuation process. Review and approval of a model for use may include benchmarking the model against relevant third party valuations, testing sample trades in the model, backtesting the results of the model against actual trades and stress-testing the sensitivity of the pricing model using varying inputs and assumptions.  In addition, recently executed comparable transactions and other observable market data are considered for purposes of validating assumptions underlying the model. Models are independently reviewed and validated by Risk Management annually or more frequently if market conditions or use of the valuation model changes.

Investments in Managed Funds

Investments in managed funds include our investments in funds managed by us and our investments in related party managed funds. Investments in nonconsolidated managed funds are accounted for at fair value based on the net asset value (“NAV”) of the funds provided by the fund managers with gains or losses included in the Consolidated Statements of Operations.

Asset management fees and investment income from managed funds include revenues we earn from management, administrative and performance fees from funds and accounts managed by us, revenues from management and performance fees we earn from related-party managed funds and investment income from our investments in these funds. We earn fees in connection with management and investment advisory services performed for various funds and managed accounts. These fees are based on assets under management or an agreed upon notional amount and may include performance fees based upon the performance of the funds. Management and administrative fees are generally recognized over the period that the related service is provided. Generally, performance fees are earned when the return on assets under management exceeds certain benchmark returns, “high-water marks” or other performance targets. Performance fees are accrued (or reversed) on a monthly basis based on measuring performance to date versus any relevant benchmark return hurdles stated in the investment management agreement. Performance fees are not subject to adjustment once the measurement period ends (generally annual periods) and the performance fees have been realized.

Loans to and Investments in Associated Companies

Loans to and investments in associated companies include investments in private equity and other operating entities in which we exercise significant influence over operating and capital decisions and loans issued in connection with such investments. Loans to and investments in associated companies are accounted for using the equity method. See Note 10 for additional information regarding certain of these investments.

Under the equity method of accounting, our share of the investee’s underlying net income or loss is recorded as Income (loss) related to associated companies, or as part of Other revenues if such investees are considered to be an extension of our business.  Income (loss) for investees for which the fair value option was elected is reported as Principal transactions revenues.

Receivables

At December 31, 2017 and 2016, Receivables include receivables from brokers, dealers and clearing organizations of $2,635.2 million and $2,062.9 million, respectively, and receivables from customers of securities operations of $1,563.8 million and $843.1 million, respectively.

Securities Borrowed and Securities Loaned

Securities borrowed and securities loaned are carried at the amounts of cash collateral advanced and received in connection with the transactions and accounted for as collateralized financing transactions. In connection with both trading and brokerage activities, Jefferies borrows securities to cover short sales and to complete transactions in which customers have failed to deliver securities by the required settlement date, and lend securities to other brokers and dealers for similar purposes. Jefferies has an active securities borrowed and lending matched book business in which it borrows securities from one party and lends them to another party. When Jefferies borrows securities, it generally provides cash to the lender as collateral, which is reflected in the Consolidated Statements of Financial Condition as Securities borrowed. Jefferies earns interest revenues on this cash collateral. Similarly, when Jefferies lends securities to another party, that party provides cash to Jefferies as collateral, which is reflected in the Consolidated Statements of Financial Condition as Securities loaned. Jefferies pays interest expense on the cash collateral received from the party borrowing the securities. The initial collateral advanced or received approximates or is greater than the fair value of the securities borrowed or loaned. Jefferies monitors the fair value of the securities borrowed and loaned on a daily basis and requests additional collateral or returns excess collateral, as appropriate.

Securities Purchased Under Agreements to Resell and Securities Sold Under Agreements to Repurchase

Securities purchased under agreements to resell and Securities sold under agreements to repurchase (collectively "repos") are accounted for as collateralized financing transactions and are recorded at their contracted resale or repurchase amount plus accrued interest. Jefferies earns and incurs interest over the term of the repo, which is reflected in Interest revenue and Interest expense in the Consolidated Statements of Operations on an accrual basis. Repos are presented in the Consolidated Statements of Financial Condition on a net-basis-by counterparty, where permitted by GAAP. The fair value of the underlying securities is monitored daily versus the related receivable or payable balances. Should the fair value of the underlying securities decline or increase, additional collateral is requested or excess collateral is returned, as appropriate.

Property, Equipment and Leasehold Improvements

Property, equipment and leasehold improvements are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization are provided principally on the straight-line method over the estimated useful lives of the assets or, if less, the term of the underlying lease.

Impairment of Long-Lived Assets

We evaluate our long-lived assets for impairment whenever events or changes in circumstances indicate, in management’s judgment, that the carrying value of such assets may not be recoverable. When testing for impairment, we group our long-lived assets with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities (or asset group). The determination of whether an asset group is recoverable is based on management’s estimate of undiscounted future cash flows directly attributable to the asset group as compared to its carrying value. If the carrying amount of the asset group is greater than the undiscounted cash flows, an impairment loss would be recognized for the amount by which the carrying amount of the asset group exceeds its estimated fair value.

In 2015, we recorded impairment charges in Selling, general and other expenses of $27.7 million, primarily related to a $20.3 million impairment at JETX and an impairment charge related to National Beef's Brawley plant of $4.7 million. For the oil and gas impairment test related to proved properties, we compare expected undiscounted future net cash flows to the unamortized capitalized cost of the asset. If the future undiscounted net cash flows are lower than the unamortized capital cost, we reduce the capitalized cost to fair market value. We used a third party reserve report in which the cash flows were calculated using West Texas Intermediate (oil) and Henry Hub (gas) NYMEX futures prices as of December 31, 2015. For one of our oil fields, the future undiscounted net cash flows were lower than the unamortized capital cost and as a result, we wrote off the total capital cost.

In 2016, JETX recorded impairment charges in Selling, general and other expenses of $56.3 million related to write-downs of unproved oil and gas properties. JETX assesses its unproved oil and gas properties for impairment based on remaining lease terms, drilling results or future plans to develop acreage and they record impairment expense for any decline in value. In the third quarter of 2016, JETX curtailed development of both its southern acreage in the East Eagle Ford and its Houston County acreage. As a result, an impairment was recorded for the difference between the carrying value and the estimated net realizable value of the acreage.

In 2017, JETX decided to focus on its other higher returning acreage and as a result wrote off the remaining carrying value for its Houston County acreage. JETX recorded an impairment charge of $10.1 million in Selling, general and other expenses in the third quarter of 2017 related to the write-down of unproved oil and gas properties.

Substantially all of our operating businesses sell products or services that are impacted by general economic conditions in the U.S. and to a lesser extent internationally. In recent years, general economic conditions reduced the demand for products or services sold by our operating subsidiaries and/or resulted in reduced pricing for products or services. A worsening of current economic conditions could cause a decline in estimated future cash flows expected to be generated by our operations and investments. If future undiscounted cash flows are estimated to be less than the carrying amounts of the asset groups used to generate those cash flows in subsequent reporting periods, particularly for those with large investments in intangible assets, property and equipment and other long-lived assets (for example, Jefferies, National Beef, manufacturing, oil and gas production and development and certain associated company investments), impairment charges would have to be recorded.

Intangible Assets, Net and Goodwill

Intangible Assets.  Intangible assets deemed to have finite lives are generally amortized on a straight-line basis over their estimated useful lives, where the useful life is the period over which the asset is expected to contribute directly, or indirectly, to our future cash flows. Intangible assets are reviewed for impairment on an interim basis when certain events or circumstances exist. If future undiscounted cash flows are estimated to be less than the carrying amounts of the asset groups used to generate those cash flows in subsequent reporting periods, particularly for those with large investments in amortizable intangible assets, impairment charges would have to be recorded.

An intangible asset with an indefinite useful life is not amortized but assessed for impairment annually, or more frequently, when certain events or circumstances exist indicating an assessment for impairment is necessary. Impairment exists when the carrying amount exceeds its fair value. Fair value will be determined using valuation techniques consistent with what a market participant would use. All of our indefinite-lived intangible assets were recognized in connection with the Jefferies acquisition, and our annual impairment testing date for Jefferies is as of August 1.

Goodwill.  At acquisition, we allocate the cost of a business acquisition to the specific tangible and intangible assets acquired and liabilities assumed based upon their fair values. Significant judgments and estimates are often made by management to determine these values, and may include the use of appraisals, consideration of market quotes for similar transactions, use of discounted cash flow techniques or consideration of other information we believe to be relevant. Any excess of the cost of a business acquisition over the fair values of the net assets and liabilities acquired is recorded as goodwill, which is not amortized to expense. Substantially all of our goodwill was recognized in connection with the Jefferies acquisition.

At least annually, and more frequently if warranted, we will assess whether goodwill has been impaired. If the estimated fair value exceeds the carrying value, goodwill at the reporting unit level is not impaired. If the estimated fair value is less than carrying value, further analysis is necessary to determine the amount of impairment, if any, by comparing the implied fair value of the reporting unit’s goodwill to the carrying value of the reporting unit’s goodwill. The fair values will be based on widely accepted valuation techniques that we believe market participants would use, although the valuation process requires significant judgment and often involves the use of significant estimates and assumptions. The methodologies we utilize in estimating fair value include market capitalization, price-to-book multiples of comparable exchange traded companies, multiples of merger and acquisitions of similar businesses and/or projected cash flows. The estimates and assumptions used in determining fair value could have a significant effect on whether or not an impairment charge is recorded and the magnitude of such a charge. Adverse market or economic events could result in impairment charges in future periods. Our annual goodwill impairment testing date related to Jefferies is as of August 1 and National Beef as of December 31.

Inventories and Cost of Sales

National Beef’s inventories consist primarily of beef products, beef by-products and supplies, and are stated at the lower of cost or net realizable value, with cost principally determined under the first-in-first-out method for beef products and average cost for supplies.

Manufacturing inventories are stated at the lower of cost or net realizable value, with cost principally determined under the first-in-first-out method. Manufacturing cost of sales principally includes product and manufacturing costs, inbound and outbound shipping costs and handling costs.

National Beef and manufacturing inventories are classified as Other assets in the Consolidated Statements of Financial Condition.

Payables, expense accruals and other liabilities

At December 31, 2017 and 2016, Payables, expense accruals and other liabilities include payables to brokers, dealers and clearing organizations of $2,228.9 million and $3,290.4 million, respectively, and payables to customers of securities operations of $2,664.0 million and $2,297.3 million, respectively.

Income Taxes

We record a valuation allowance to reduce our net deferred tax asset to the net amount that is more likely than not to be realized.  If in the future we determine that it is more likely than not that we will be able to realize our net deferred tax asset in excess of our net recorded amount, an adjustment to increase the net deferred tax asset would increase income in such period. If in the future we were to determine that we would not be able to realize all or part of our recorded net deferred tax asset, an adjustment to decrease the net deferred tax asset would be charged to income in such period. We are required to consider all available evidence, both positive and negative, and to weigh the evidence when determining whether a valuation allowance is required and the amount of such valuation allowance. Generally, greater weight is required to be placed on objectively verifiable evidence when making this assessment, in particular on recent historical operating results.

Our estimate of future taxable income considers all available evidence, both positive and negative, about our operating businesses and investments, includes an aggregation of individual projections for each significant operating business and investment, estimated apportionment factors for state and local taxing jurisdictions and includes all future years that we estimate we will have available net operating loss carryforwards (“NOLs”) (until 2035). We believe that our estimate of future taxable income is reasonable but inherently uncertain, and if our current or future operations and investments generate taxable income different than the projected amounts, further adjustments to the valuation allowance are possible. The current balance of the deferred tax valuation allowance principally reserves for NOLs of certain subsidiaries that are not available to offset income generated by other members of the consolidated tax return group.

We also record reserves for unrecognized tax benefits based on our assessment of the probability of successfully sustaining tax filing positions.  Interest and penalties, if any, are recorded as components of income tax expense. Management exercises significant judgment when assessing the probability of successfully sustaining tax filing positions, and in determining whether a contingent tax liability should be recorded and if so estimating the amount. If our tax filing positions are successfully challenged, payments could be required that are in excess of reserved amounts or we may be required to reduce the carrying amount of our net deferred tax asset, either of which could be significant to our Consolidated Statement of Financial Condition or results of operations.

Share-based Compensation

Share-based awards are measured based on the fair value of the award as determined in accordance with GAAP and recognized over the required service or vesting period. Certain executive share-based awards contain market, performance and service conditions. Market conditions are incorporated into the grant-date fair value using a Monte Carlo valuation model. Compensation expense for awards with market conditions is recognized over the service period and is not reversed if the market condition is not met. Awards with performance conditions are amortized over the service period if it is determined that it is probable that the performance condition will be achieved. The fair value of options and warrants are estimated at the date of grant using the Black-Scholes option pricing model. Expected forfeitures are included in determining share-based compensation expense.

Foreign Currency Translation

Assets and liabilities of foreign subsidiaries are translated to U.S. dollars using the currency exchange rates at the end of the relevant period. Revenues and expenses are translated at average exchange rates during the period. The effects of exchange rate changes on the translation of the balance sheets, net of hedging gains or losses and taxes, if any, are included in other comprehensive income (loss) in the Consolidated Statements of Comprehensive Income (Loss) and classified as Accumulated other comprehensive income in the Consolidated Statements of Financial Condition and Consolidated Statements of Changes in Equity. Gains or losses resulting from Jefferies foreign currency transactions are included in Principal transactions in the Consolidated Statements of Operations.

Earnings per Common Share

Basic earnings per share ("EPS") is computed by dividing net earnings available to common shareholders by the weighted average number of common shares outstanding and certain other shares committed to be, but not yet issued. Net earnings available to common shareholders represent net earnings to common shareholders reduced by the allocation of earnings to participating securities. Losses are not allocated to participating securities. Common shares outstanding and certain other shares committed to be, but not yet issued, include restricted stock and restricted stock units ("RSUs") for which no future service is required. Diluted EPS is computed by dividing net earnings available to common shareholders plus dividends on dilutive mandatorily redeemable convertible preferred shares and interest on convertible notes by the weighted average number of common shares outstanding and certain other shares committed to be, but not yet issued, plus all dilutive common stock equivalents outstanding during the period.

Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and, therefore, are included in the earnings allocation in computing earnings per share under the two-class method of earnings per share. Restricted stock and RSUs granted as part of share-based compensation contain nonforfeitable rights to dividends and dividend equivalents, respectively, and therefore, prior to the requisite service being rendered for the right to retain the award, restricted stock and RSUs meet the definition of a participating security. As such, we calculate basic and diluted earnings per share under the two-class method. RSUs granted under the senior executive compensation plan are not considered participating securities as the rights to dividend equivalents are forfeitable. See Note 17 for more information regarding the senior executive compensation plan.

Securitization Activities

Jefferies engages in securitization activities related to corporate loans, consumer loans, commercial mortgage loans and mortgage-backed and other asset-backed securities. Such transfers of financial assets are accounted for as sales when Jefferies has relinquished control over the transferred assets. The gain or loss on sale of such financial assets depends, in part, on the previous carrying amount of the assets involved in the transfer allocated between the assets sold and the retained interests, if any, based upon their respective fair values at the date of sale. Jefferies may retain interests in the securitized financial assets as one or more tranches of the securitization. These retained interests are included within Trading assets in the Consolidated Statements of Financial Condition at fair value. Any changes in the fair value of such retained interests are recognized within Principal transactions in the Consolidated Statements of Operations.

When a transfer of assets does not meet the criteria of a sale, the transfer is accounted for as a secured borrowing and Jefferies continues to recognize the assets of a secured borrowing, and recognize the associated financing in Other secured financings in the Consolidated Statements of Financial Condition.

Beginning in 2014, another of our subsidiaries utilized a special purpose entity to securitize automobile loans receivable. This special purpose entity is a variable interest entity and our subsidiary is the primary beneficiary; the related assets and the secured borrowings are recognized in the Consolidated Statement of Financial Condition. These secured borrowings do not have recourse to our subsidiary’s general credit.

Contingencies

In the normal course of business, we have been named, from time to time, as a defendant in legal and regulatory proceedings. We are also involved, from time to time, in other exams, investigations and similar reviews (both formal and informal) by governmental and self-regulatory agencies regarding our businesses, certain of which may result in judgments, settlements, fines, penalties or other injunctions.

We recognize a liability for a contingency when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. If the reasonable estimate of a probable loss is a range, we accrue the most likely amount of such loss, and if such amount is not determinable, then we accrue the minimum in the range as the loss accrual. The determination of the outcome and loss estimates requires significant judgment on the part of management, can be highly subjective and is subject to significant change with the passage of time as more information becomes available. Estimating the ultimate impact of litigation matters is inherently uncertain, in particular because the ultimate outcome will rest on events and decisions of others that may not be within our power to control. We do not believe that any of our current litigation will have a significant adverse effect on our consolidated financial position, results of operations or liquidity; however, if amounts paid at the resolution of litigation are in excess of recorded reserve amounts, the excess could be significant in relation to results of operations for that period. For further information, see Note 24.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Accounting Developments

Accounting Developments

Accounting Developments - Adopted Accounting Standards

Share-Based Payments to Employees. In January 2017, we adopted the Financial Accounting Standards Board's ("FASB") new guidance that simplifies and improves accounting for share-based payments. The amendments include the recognition of all excess tax benefits and tax deficiencies as income tax expense or benefit in the statement of operations and changes to the timing of recognition of excess tax benefits, the accounting for forfeitures, classification of awards as either equity or liabilities and classification on the statement of cash flows. The adoption of this guidance did not have a significant impact on our consolidated financial statements. We elected to account for forfeitures as they occur, which results in dividends and dividend equivalents originally charged against retained earnings for forfeited shares to be reclassified to compensation expense in the period in which the forfeiture occurs.

Income Statement - Reporting Comprehensive Income. In February 2018, the FASB issued new guidance that allows companies the option to reclassify from accumulated other comprehensive income to retained earnings stranded tax effects resulting from the newly enacted federal corporate income tax rate. The amount of the reclassification would be the difference between the historical corporate income tax rate and the newly enacted corporate income tax rate. This will eliminate the stranded tax effects associated with the change in the federal corporate income tax rate in the Tax Act and would improve the usefulness of information reported to financial statement users. The Company uses the portfolio approach relating to the release of stranded tax effects. Under the portfolio approach, the net unrealized gains or losses recorded in accumulated other comprehensive income would be eliminated only on the date the entire portfolio of available for sale securities is sold or otherwise disposed of. The guidance is effective for annual and interim periods beginning after December 15, 2018 and early adoption is permitted. We adopted this guidance as of December 31, 2017 and elected to make the reclassification, resulting in a reclassification adjustment of $9.2 million.

Accounting Developments - Accounting Standards to be Adopted in Future Periods

Revenue Recognition.  In May 2014, the FASB issued new guidance that defines how companies report revenues from contracts with customers, and also requires enhanced disclosures. The core principle of this new guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. This guidance is effective for interim and annual periods beginning after December 15, 2017. We have adopted the new guidance as of January 1, 2018 using the modified retrospective approach with a cumulative-effect adjustment to opening retained earnings of approximately $8 million. Our implementation efforts included the identification of revenue streams within the scope of the guidance, the evaluation of certain revenue contracts and education and discussion with our consolidated subsidiaries. Based on our assessment, the impact of the adoption of the new guidance does not have a material impact on our consolidated financial statements. The below focuses on our two largest consolidated subsidiaries, whose combined revenues comprise more than 92% of our Net revenues in the Consolidated Statements of Operations for the year ended December 31, 2017.

For Jefferies, as the new revenue recognition guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, and as a result, did not have an impact on the elements of its revenues most closely associated with financial instruments, including Principal transaction revenues, Interest income and Interest expense. The new revenue standard primarily impacts the following of Jefferies revenue recognition and presentation accounting policies:

• Investment Banking Revenues. Advisory fees from mergers and acquisitions engagements are recognized at a point in time when the related transaction is completed, as the performance obligation is to successfully broker a specific transaction.

• Certain Capital Markets Revenues. Revenues associated with price stabilization activities as part of a securities underwriting were historically recognized as part of Investment banking revenues. Under the new revenue standard, revenue from these activities is recognized within Principal transaction revenues, as these revenues are not considered to be within the scope of the new standard.

• Investment Banking Advisory Expenses. Historically, expenses associated with investment banking advisory assignments were deferred until reimbursed by the client, the related fee revenue is recognized or the engagement is otherwise concluded. Under the new revenue standard, expenses are deferred only to the extent they are explicitly reimbursable by the client and the related revenue is recognized at a point in time. All other investment banking advisory related expenses, including expenses incurred related to restructuring assignments, are expensed as incurred.

• Investment Banking Underwriting and Advisory Expenses. Expenses have historically been recorded net of client reimbursements and/or netted against revenues. Under the new revenue standard, all investment banking expenses will be recognized within their respective expense category on the consolidated statements of operations and any expense reimbursements will be recognized as Investment banking revenues (i.e., expenses are no longer recorded net of client reimbursements and are not netted against revenues).

• Asset Management Fees. In certain asset management fee arrangements, Jefferies and LAM receive performance-based fees, which vary with performance or, in certain cases, are earned when the return on assets under management exceed certain benchmark returns or other performance targets. Historically, performance fees have been accrued (or reversed) quarterly based on measuring performance to date versus any relevant benchmark return hurdles stated in the investment management agreement. Under the new revenue standard, performance fees are considered variable as they are subject to fluctuation (e.g., based on market performance) and/or are contingent on a future event during the measurement period (e.g., meeting a specified benchmark rate) and are recognized only to the extent it is not probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty is resolved. Accordingly, performance fee revenue will generally be recognized only at the end of the performance period to the extent that the benchmark return has been met.

National Beef earns over 95% of its revenues through the sale of beef, pork and beef by-products. Agreements with customers for these sales typically consist of the type and quantity of products to be delivered, the unit price of each product, the estimated delivery date and credit and payment terms. The transaction price is generally fixed at this time and revenue is recognized when the customer takes control of the product. The impact of the new guidance does not materially impact how revenue is recognized for this revenue stream.

Financial Instruments. In January 2016, the FASB issued new guidance that affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. The guidance is effective for annual and interim periods beginning after December 15, 2017. We do not believe the new guidance related to equity investments and the presentation and disclosure requirements of financial instruments will have a material impact on our consolidated financial statements. We have adopted the new guidance as of January 1, 2018 with a cumulative-effect increase to opening retained earnings of approximately $28 million and a corresponding decrease to Accumulated other comprehensive income. Early adoption was permitted for the accounting guidance on financial liabilities under the fair value option and we adopted this guidance in the first quarter of 2016. The adoption of the guidance on financial liabilities under the fair value option did not have a material impact on our consolidated financial statements.

Leases. In February 2016, the FASB issued new guidance that affects the accounting and disclosure requirements for leases. The FASB requires the recognition of lease assets and lease liabilities on the statement of financial condition. The guidance is effective for annual and interim periods beginning after December 15, 2018. We are currently evaluating the impact this new guidance will have on our consolidated financial statements.

Financial Instruments - Credit Losses. In June 2016, the FASB issued new guidance for estimating credit losses on certain types of financial instruments by introducing an approach based on expected losses. The guidance is effective for annual and interim periods beginning after December 15, 2019. We are currently evaluating the impact this new guidance will have on our consolidated financial statements.

Cash Flow Classifications. In August 2016, the FASB issued new guidance to reduce the diversity in practice in how certain transactions are classified in the statement of cash flows. The guidance adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The guidance is effective for annual and interim periods beginning after December 15, 2017. In November 2016, the FASB issued new guidance on restricted cash. The guidance requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. The guidance is effective for annual and interim periods beginning after December 15, 2017. We do not believe the new guidance will have a material impact on our consolidated financial statements.

Goodwill. In January 2017, the FASB issued new guidance for simplifying goodwill impairment testing. The guidance is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted. We do not believe the new guidance will have a material impact on our consolidated financial statements.

Retirement Benefits. In March 2017, the FASB issued new guidance for improving the presentation of net periodic pension costs in the statement of operations. The update also allows the service cost to be eligible for capitalization, when applicable. The guidance is effective for annual and interim periods beginning after December 15, 2017 and early adoption is permitted. We do not believe the new guidance will have a material impact on our consolidated financial statements.

Compensation. In May 2017, the FASB issued new guidance providing clarity and reducing diversity in practice and cost and complexity when accounting for a change to the terms or conditions of a share-based payment award. The guidance is effective for annual and interim periods beginning after December 15, 2017 and early adoption is permitted. We do not believe the new guidance will have a material impact on our consolidated financial statements.

Derivatives and hedging. In August 2017, the FASB issued new guidance to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. The guidance is effective for annual and interim periods beginning after December 15, 2018 and early adoption is permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements.

The following is a description of the valuation basis, including valuation techniques and inputs, used in measuring our financial assets and liabilities that are accounted for at fair value on a recurring basis:

Corporate Equity Securities

• Exchange Traded Equity Securities:  Exchange traded equity securities are measured based on quoted closing exchange prices, which are generally obtained from external pricing services, and are categorized within Level 1 of the fair value hierarchy, otherwise they are categorized within Level 2 of the fair value hierarchy. To the extent these securities are actively traded, valuation adjustments are not applied.

• Non-Exchange Traded Equity Securities:  Non-exchange traded equity securities are measured primarily using broker quotations, pricing data from external pricing services and prices observed from recently executed market transactions and are categorized within Level 2 of the fair value hierarchy. Where such information is not available, non-exchange traded equity securities are categorized within Level 3 of the fair value hierarchy and measured using valuation techniques involving quoted prices of or market data for comparable companies, similar company ratios and multiples (e.g., price/Earnings before interest, taxes, depreciation and amortization ("EBITDA"), price/book value), discounted cash flow analyses and transaction prices observed from subsequent financing or capital issuance by Jefferies. When using pricing data of comparable companies, judgment must be applied to adjust the pricing data to account for differences between the measured security and the comparable security (e.g., issuer market capitalization, yield, dividend rate, geographical concentration).

• Equity Warrants:  Non-exchange traded equity warrants are measured primarily using pricing data from external pricing services, prices observed from recently executed market transactions and broker quotations and are categorized within Level 2 of the fair value hierarchy. Where such information is not available, non-exchange traded equity warrants are generally categorized within Level 3 of the fair value hierarchy and are measured using the Black-Scholes model with key inputs impacting the valuation including the underlying security price, implied volatility, dividend yield, interest rate curve, strike price and maturity date.

Corporate Debt Securities

• Corporate Bonds:  Corporate bonds are measured primarily using pricing data from external pricing services and broker quotations, where available, prices observed from recently executed market transactions and bond spreads or credit default swap spreads of the issuer adjusted for basis differences between the swap curve and the bond curve. Corporate bonds measured using these valuation methods are categorized within Level 2 of the fair value hierarchy. If broker quotes, pricing data or spread data is not available, alternative valuation techniques are used including cash flow models incorporating interest rate curves, single name or index credit default swap curves for comparable issuers and recovery rate assumptions. Corporate bonds measured using alternative valuation techniques are categorized within Level 3 of the fair value hierarchy and are a limited portion of our corporate bonds.

• High Yield Corporate and Convertible Bonds:  A significant portion of our high yield corporate and convertible bonds are categorized within Level 2 of the fair value hierarchy and are measured primarily using broker quotations and pricing data from external pricing services, where available, and prices observed from recently executed market transactions of Institutional size. Where pricing data is less observable, valuations are categorized within Level 3 and are based on pending transactions involving the issuer or comparable issuers, prices implied from an issuer’s subsequent financing or recapitalization, models incorporating financial ratios and projected cash flows of the issuer and market prices for comparable issuers.

Collateralized Debt Obligations and Collateralized Loan Obligations

CDOs and CLOs are measured based on prices observed from recently executed market transactions of the same or similar security or based on valuations received from third party brokers or data providers and are categorized within Level 2 or Level 3 of the fair value hierarchy depending on the observability and significance of the pricing inputs. Valuation that is based on recently executed market transactions of similar securities incorporates additional review and analysis of pricing inputs and comparability criteria, including, but not limited to, collateral type, tranche type, rating, origination year, prepayment rates, default rates, and loss severity.

U.S. Government and Federal Agency Securities

• U.S. Treasury Securities:  U.S. Treasury securities are measured based on quoted market prices and categorized within Level 1 of the fair value hierarchy.

• U.S. Agency Debt Securities:  Callable and non-callable U.S. agency debt securities are measured primarily based on quoted market prices obtained from external pricing services and are generally categorized within Level 1 or Level 2 of the fair value hierarchy.

Municipal Securities

Municipal securities are measured based on quoted prices obtained from external pricing services and are generally categorized within Level 2 of the fair value hierarchy.

Sovereign Obligations

Sovereign government obligations are measured based on quoted market prices obtained from external pricing services, where available, or recently executed independent transactions of comparable size. To the extent external price quotations are not available or recent transactions have not been observed, valuation techniques incorporating interest rate yield curves and country spreads for bonds of similar issuers, seniority and maturity are used to determine fair value of sovereign bonds or obligations. Sovereign government obligations are classified in Level 1 or Level 2 of the fair value hierarchy, primarily based on the country of issuance.

Residential Mortgage-Backed Securities

• Agency Residential Mortgage-Backed Securities:  Agency residential mortgage-backed securities include mortgage pass-through securities (fixed and adjustable rate), collateralized mortgage obligations and principal-only securities and are generally measured using market price quotations from external pricing services and categorized within Level 2 of the fair value hierarchy.

• Agency Residential Interest-Only and Inverse Interest-Only Securities ("agency Inverse IOs"):  The fair value of agency Inverse IOs is estimated using expected future cash flow techniques that incorporate prepayment models and other prepayment assumptions to amortize the underlying mortgage loan collateral. We use prices observed from recently executed transactions to develop market-clearing spread and yield curve assumptions. Valuation inputs with regard to the underlying collateral incorporate weighted average coupon, loan-to-value, credit scores, geographic location, maximum and average loan size, originator, servicer, and weighted average loan age. Agency Inverse IOs are categorized within Level 2 of the fair value hierarchy. We also use vendor data in developing our assumptions, as appropriate.

• Non-Agency Residential Mortgage-Backed Securities:  The fair value of non-agency residential mortgage-backed securities is determined primarily using discounted cash flow methodologies and securities are categorized within Level 2 or Level 3 of the fair value hierarchy based on the observability and significance of the pricing inputs used. Performance attributes of the underlying mortgage loans are evaluated to estimate pricing inputs, such as prepayment rates, default rates and the severity of credit losses. Attributes of the underlying mortgage loans that affect the pricing inputs include, but are not limited to, weighted average coupon; average and maximum loan size; loan-to-value; credit scores; documentation type; geographic location; weighted average loan age; originator; servicer; historical prepayment, default and loss severity experience of the mortgage loan pool; and delinquency rate. Yield curves used in the discounted cash flow models are based on observed market prices for comparable securities and published interest rate data to estimate market yields. In addition, broker quotes, where available, are also referenced to compare prices primarily on interest-only securities.

Commercial Mortgage-Backed Securities

• Agency Commercial Mortgage-Backed Securities:  Government National Mortgage Association (“GNMA”) project loan bonds are measured based on inputs corroborated from and benchmarked to observed prices of recent securitization transactions of similar securities with adjustments incorporating an evaluation of various factors, including prepayment speeds, default rates, and cash flow structures as well as the likelihood of pricing levels in the current market environment. Federal National Mortgage Association (“FNMA”) Delegated Underwriting and Servicing (“DUS”) mortgage-backed securities are generally measured by using prices observed for recently executed market transactions to estimate market-clearing spread levels for purposes of estimating fair value. GNMA project loan bonds and FNMA DUS mortgage-backed securities are categorized within Level 2 of the fair value hierarchy.

• Non-Agency Commercial Mortgage-Backed Securities:  Non-agency commercial mortgage-backed securities are measured using pricing data obtained from external pricing services and prices observed from recently executed market transactions and are categorized within Level 2 and Level 3 of the fair value hierarchy.

Other Asset-Backed Securities

Other asset-backed securities include, but are not limited to, securities backed by auto loans, credit card receivables, student loans and other consumer loans and are categorized within Level 2 and Level 3 of the fair value hierarchy. Valuations are primarily determined using pricing data obtained from external pricing services and broker quotes and prices observed from recently executed market transactions.

Loans and Other Receivables

• Corporate Loans:  Corporate loans categorized within Level 2 of the fair value hierarchy are measured based on market price quotations where market price quotations from external pricing services are supported by transaction data. Corporate loans categorized within Level 3 of the fair value hierarchy are measured based on price quotations that are considered to be less transparent, market prices for debt securities of the same creditor and estimates of future cash flow incorporating assumptions regarding creditor default and recovery rates and consideration of the issuer’s capital structure.

• Participation Certificates in Agency Residential Loans: Valuations of participation certificates in agency residential loans are based on observed market prices of recently executed purchases and sales of similar loans. The loan participation certificates are categorized within Level 2 of the fair value hierarchy given the observability and volume of recently executed transactions and availability of data provider pricing.

• Project Loans and Participation Certificates in GNMA Project and Construction Loans:  Valuations of participation certificates in GNMA project and construction loans are based on inputs corroborated from and benchmarked to observed prices of recent securitizations with similar underlying loan collateral to derive an implied spread. Securitization prices are adjusted to estimate the fair value of the loans incorporating an evaluation for various factors, including prepayment speeds, default rates and cash flow structures as well as the likelihood of pricing levels in the current market environment. The measurements are categorized within Level 2 of the fair value hierarchy given the observability and volume of recently executed transactions.

• Consumer Loans and Funding Facilities:  Consumer and small business whole loans and related funding facilities are valued based on observed market transactions and incorporating valuation inputs including, but not limited to, delinquency and default rates, prepayment rates, borrower characteristics, loan risk grades and loan age. These assets are categorized within Level 2 or Level 3 of the fair value hierarchy.

• Escrow and Trade Claim Receivables:  Escrow and trade claim receivables are categorized within Level 3 of the fair value hierarchy where fair value is estimated based on reference to market prices and implied yields of debt securities of the same or similar issuers. Escrow and trade claim receivables are categorized within Level 2 of the fair value hierarchy where fair value is based on recent trade activity in the same receivable.

Derivatives

• Listed Derivative Contracts:  Listed derivative contracts that are actively traded are measured based on quoted exchange prices, broker quotes or vanilla option valuations models, such as Black-Scholes, using observable valuation inputs from the principal market. Exchange quotes and/or valuation inputs are generally obtained from external vendors and pricing services. Brokers quotes are validated directly through observable and tradeable quotes. Listed derivative contracts that use unadjusted exchange close prices are generally classified within Level 1 of the fair value hierarchy. All other listed derivative contracts are generally categorized within Level 2 of the fair value hierarchy.

• Over-the-counter ("OTC") Derivative Contracts:  OTC derivative contracts are generally valued using models, whose inputs reflect assumptions that we believe market participants would use in valuing the derivative in a current transaction. Inputs to valuation models are appropriately calibrated to market data. For many OTC derivative contracts, the valuation models do not involve material subjectivity as the methodologies do not entail significant judgment and the inputs to valuation models do not involve a high degree of subjectivity as the valuation model inputs are readily observable or can be derived from actively quoted markets. OTC derivative contracts are primarily categorized within Level 2 of the fair value hierarchy given the observability and significance of the inputs to the valuation models. Where significant inputs to the valuation are unobservable, derivative instruments are categorized within Level 3 of the fair value hierarchy.

OTC options include OTC equity, foreign exchange, interest rate and commodity options measured using various valuation models, such as the Black-Scholes, with key inputs including the underlying security price, foreign exchange spot rate, commodity price, implied volatility, dividend yield, interest rate curve, strike price and maturity date. Discounted cash flow models are utilized to measure certain OTC derivative contracts including the valuations of our interest rate swaps, which incorporate observable inputs related to interest rate curves, valuations of our foreign exchange forwards and swaps, which incorporate observable inputs related to foreign currency spot rates and forward curves and valuations of our commodity swaps and forwards, which incorporate observable inputs related to commodity spot prices and forward curves. Discounted cash flow models are also utilized to measure certain variable funding note swaps, which are backed by CLOs and incorporate constant prepayment rate, constant default rate and loss severity assumptions. Credit default swaps include both index and single-name credit default swaps. External prices are available as inputs in measuring index credit default swaps and single-name credit default swaps. For commodity and equity total return swaps, market prices are generally observable for the underlying asset and used as the basis for measuring the fair value of the derivative contracts. Total return swaps executed on other underlyings are measured based on valuations received from external pricing services.

• National Beef Derivatives: National Beef uses futures contracts in order to reduce its exposure associated with entering into firm commitments to purchase live cattle at prices determined prior to the delivery of the cattle as well as firm commitments to sell certain beef products at sales prices determined prior to shipment. The futures contracts and their related firm purchase commitments are accounted for at fair value, which are classified as Level 1 or Level 2 within the fair value hierarchy. Certain firm commitments for live cattle purchases and all firm commitments for sales are treated as normal purchases and sales and therefore not marked to market. Fair values classified as Level 1 are calculated based on the quoted market prices of identical assets or liabilities compared to National Beef's cost of those same assets or liabilities. Fair values classified as Level 2 are calculated based on the difference between the contracted price for live cattle and the relevant quoted market price for live cattle futures.

• Oil Futures Derivatives: Vitesse uses swaps and call and put options in order to reduce exposure to future oil price fluctuations. Vitesse accounts for the derivative instruments at fair value, which are classified as Level 2 within the fair value hierarchy. Fair values classified as Level 2 are determined under the income valuation technique using an option-pricing model that is based on directly or indirectly observable inputs.

Investments at Fair Value

Investments at fair value included in Trading assets on the Consolidated Statements of Financial Condition include direct equity investments in private companies, which are measured at fair value using valuation techniques involving quoted prices of or market data for comparable companies, similar company ratios and multiples (e.g., price/EBITDA, price/book value), discounted cash flow analysis and transaction prices observed for subsequent financing or capital issuance by the company. Direct equity investments in private companies are categorized within Level 2 or Level 3 of the fair value hierarchy.  Additionally, investments at fair value include investments in insurance contracts relating to Jefferies defined benefit plan in Germany. Fair value for the insurance contracts are determined using a third party and is categorized within Level 3 of the fair value hierarchy. 

Investment in FXCM

FXCM is a provider of online foreign exchange trading services. In January 2015, we entered into a credit agreement with FXCM, and provided FXCM a $300 million senior secured term loan due January 2017 (the term of which was subsequently extended to January 2019), with rights to a variable proportion of certain future distributions in connection with an FXCM sale of assets or certain other events, and to require a sale of FXCM beginning in January 2018. The loan had an initial interest rate of 10% per annum, increasing by 1.5% per annum each quarter, not to exceed 20.5% per annum. During the year ended December 31, 2017, interest accrued at 20.5% per annum. During the year ended December 31, 2017, we received $114.9 million of principal and interest from FXCM and $69.9 million of principal remained outstanding under the term loan as of December 31, 2017. Through December 31, 2017, we have received cumulatively $331.6 million of principal, interest and fees from our initial $279.0 million investment in FXCM.

Through September 1, 2016, the total amount of our investment in FXCM was reported within Trading assets, at fair value in our Consolidated Statements of Financial Condition, and unrealized and realized changes in value, including the component related to interest income on the loan, were included within Principal transactions in the Consolidated Statements of Operations. We recorded gains (losses) in Principal transactions of $23.2 million during the year ended December 31, 2017 from our term loan and $(54.6) million and $491.3 million during the years ended December 31, 2016 and 2015, respectively, from our term loan and related rights.

On September 1, 2016, we, Global Brokerage Inc. ("Global Brokerage") and Global Brokerage Holdings entered into an agreement that amended the terms of our loan and associated rights. On November 10, 2017, the terms of our loan and associated rights were amended further. Among other changes, the amendments during 2016 and 2017 extended the repayment date of the remaining loan balance to January 2019; and exchanged our rights for a 50% voting interest in FXCM and up to 75% of all distributions. Through these amendments, we also gained the right to appoint three of six board members for FXCM. We have the right, as does Global Brokerage Holdings, the owner of the remaining 50% of FXCM voting interest that is not held by Leucadia, to require a sale of FXCM beginning in January 2018. Distributions to Leucadia under the amended agreements are now: 100% until amounts due under the loan are repaid; 50% of the next $350 million; then 90% of the next $600 million; and 60% of all amounts thereafter.

Through the amendment on September 1, 2016 we gained the ability to significantly influence FXCM through our seats on the board of directors. As a result, we classify our equity investment in FXCM in our December 31, 2017 and 2016 Consolidated Statements of Financial Condition as Loans to and investments in associated companies. We account for our equity interest on a one month lag. As the amendments only extended the maturity of the term loan, we continue to use the fair value option and classify our term loan within Trading assets, at fair value.

During February 2017, Global Brokerage Holdings and FXCM's U.S. subsidiary, Forex Capital Markets LLC ("FXCM U.S.") settled complaints filed by the National Futures Association ("NFA") and the Commodity Futures Trading Commission ("CFTC") against FXCM U.S. and certain of its principals relating to matters that occurred between 2010 and 2014. As part of the settlements, FXCM U.S. withdrew from business and sold FXCM U.S.'s customer accounts. FXCM also implemented a restructuring plan that included the termination of approximately 22% of its global workforce. The proceeds from the sale of the U.S. accounts, net of closure and severance costs, as well as regulatory capital released after the sale, has been used to pay down the Leucadia term loan.

FXCM is considered a variable interest entity ("VIE") and our term loan and equity ownership are variable interests.  We have determined that we are not the primary beneficiary of FXCM because we do not have the power to direct the activities that most significantly impact FXCM’s performance. Therefore, we do not consolidate FXCM and we account for our equity interest under the equity method as an investment in an associated company.

Our maximum exposure to loss as a result of our involvement with FXCM is limited to the carrying value of the term loan ($72.8 million) and the investment in associated company ($158.9 million), which totaled $231.7 million at December 31, 2017.

We estimate the fair value of our term loan by using a valuation model with inputs including management’s assumptions concerning the amount and timing of expected cash flows, the loan’s implied credit rating and effective yield. Because of these inputs and the degree of judgment involved, we have categorized our term loan within Level 3 of the fair value hierarchy.

Nonrecurring Fair Value Measurements

As described further in Note 10, in the first quarter of 2017 we engaged an independent valuation firm to assist management in estimating the fair value of our equity investment in FXCM. Our first quarter estimate of fair value was based on a discounted cash flow and comparable public company analysis and is categorized within Level 3 of the fair value hierarchy. The discounted cash flow valuation model used inputs including management's projections of future FXCM cash flows and a discount rate of approximately 15%. The comparable public company model used market data for comparable companies including a price to EBITDA multiple of 5.4 and a price to revenue multiple of 1.5. The estimated fair value of our equity investment in FXCM was $186.7 million, which was $130.2 million lower than the carrying value at the end of the first quarter 2017. As a result, an impairment charge of $130.2 million was recorded in Income (loss) related to associated companies in the first quarter of 2017.

In 2015, we recorded impairment charges in Selling, general and other expenses of $27.7 million, primarily related to a $20.3 million impairment at JETX and an impairment charge related to National Beef's Brawley plant (which was closed in 2014) of $4.7 million. JETX owns both proved and unproved oil and gas properties that are included in Other assets in our Consolidated Statements of Financial Condition. For the oil and gas impairment test related to proved properties, we compare expected undiscounted future net cash flows to the unamortized capitalized cost of the asset. If the future undiscounted net cash flows are lower than the unamortized capital cost, we reduce the capitalized cost to fair market value. We used a third party reserve report in which the cash flows were calculated using West Texas Intermediate (oil) and Henry Hub (gas) NYMEX futures prices as of December 31, 2015. For one of our oil fields, the undiscounted net cash flows were lower than the unamortized capital cost and as a result, we wrote off the total capital cost.

In the third quarter of 2016, JETX curtailed development of both its southern acreage in the East Eagle Ford and its Houston County acreage and performed an impairment analysis of these unproved oil and gas properties. To measure the estimated fair value of the unproved properties, we used unobservable Level 3 inputs, which took into account the following factors: remaining lease terms, drilling results and/or future plans to develop the acreage. The estimated fair value of JETX's southern acreage in the East Eagle Ford and its Houston County acreage totaled $51.6 million, which was $55.0 million lower than the carrying value as of the end of third quarter of 2016. As a result, an impairment charge of $55.0 million was recorded in Selling, general and other expenses in the third quarter of 2016.

In the third quarter of 2017, JETX decided to focus on its other higher returning acreage and as a result JETX wrote off the remaining carrying value for its Houston County acreage. JETX recorded an impairment charge of $10.1 million in Selling, general and other expenses in the third quarter of 2017 related to the write-down of unproved oil and gas properties.

Other Secured Financings

Other secured financings that are accounted for at fair value include notes issued by consolidated VIEs, which are classified as Level 2 or Level 3 within the fair value hierarchy.  Fair value is based on recent transaction prices for similar assets. 

Short-term Borrowings and Long-term Debt

Short-term borrowings that are accounted for at fair value include equity-linked notes, which are generally categorized as Level 2 within the fair value hierarchy, as the fair value is based on the price of the underlying equity security. Long-term debt includes variable rate, fixed-to-floating rate, CMS (constant maturity swap) and Bermudan structured notes. These are valued using various valuation models that incorporate Jefferies own credit spread, market price quotations from external pricing sources referencing the appropriate interest rate curves, volatilities and other inputs and are generally categorized within Level 2 of the fair value hierarchy. In addition, pricing transparency has been evidenced based on transaction data from recently issued notes.

Analysis of Level 3 Assets and Liabilities for the year ended December 31, 2017

During the year ended December 31, 2017, transfers of assets of $38.2 million from Level 2 to Level 3 of the fair value hierarchy are attributed to:

• Residential mortgage-backed securities of $19.6 million and corporate debt securities of $8.3 million due to a lack of observable market transactions.

During the year ended December 31, 2017, transfers of assets of $54.9 million from Level 3 to Level 2 are attributed to:

• Loans and other receivables of $40.9 million due to greater pricing transparency supporting classification into Level 2;

Net gains on Level 3 assets were $5.9 million and net gains on Level 3 liabilities were $1.7 million for the year ended December 31, 2017. Net gains on Level 3 assets were primarily due to increased valuations of our investment in FXCM, investments at fair value and certain loans and other receivables partially offset by decreased valuations of CDOs and CLOs, other asset-backed securities and residential mortgage-backed securities. Net gains on Level 3 liabilities were primarily due to increased valuations of certain net derivatives.

Analysis of Level 3 Assets and Liabilities for the year ended December 31, 2016

During the year ended December 31, 2016, transfers of assets of $179.6 million from Level 2 to Level 3 of the fair value hierarchy are attributed to:

• CDOs and CLOs of $19.4 million, residential mortgage-backed securities of $17.5 million, commercial mortgage-backed securities of $17.4 million and other asset-backed securities of $16.9 million, for which no recent trade activity was observed for purposes of determining observable inputs;

• Loans and other receivables of $13.8 million due to a lower number of contributors for certain vendor quotes supporting classification within Level 2; and

• Corporate debt securities of $28.1 million, investments at fair value of $31.9 million and municipal securities of $28.7 million due to a lack of observable market transactions.

During the year ended December 31, 2016, transfers of assets of $133.2 million from Level 3 to Level 2 are attributed to:

• Residential mortgage-backed securities of $26.8 million, other asset-backed securities of $26.8 million and CDOs and CLOs of $15.4 million for which market trades were observed in the year for either identical or similar securities;

• Loans and other receivables of $37.8 million due to a greater number of contributors for certain vendor quotes supporting classification into Level 2; and

• Corporate equity securities of $19.2 million due to an increase in observable market transactions.

During the year ended December 31, 2016, there were transfers of loan liabilities of $10.5 million from Level 3 to Level 2 due to an increase in observable inputs in the valuation.

Net losses on Level 3 assets were $115.3 million and net gains on Level 3 liabilities were $1.9 million for the year ended December 31, 2016. Net losses on Level 3 assets were primarily due to decreased valuations of our investment in FXCM, loans and other receivables, corporate debt securities, CDOs and CLOs, other asset-backed securities, residential and commercial mortgage-backed securities and corporate equity securities partially offset by increased valuations of certain investments at fair value. Net gains on Level 3 liabilities were primarily due to increased valuations of certain net derivatives.

The following is a summary of changes in fair value of our financial assets and liabilities that have been categorized within Level 3 of the fair value hierarchy for the year ended December 31, 2015 (in thousands).

Analysis of Level 3 Assets and Liabilities for the year ended December 31, 2015

During the year ended December 31, 2015, transfers of assets of $236.7 million from Level 2 to Level 3 of the fair value hierarchy are attributed to:

• CDOs and CLOs of $69.8 million, non-agency residential mortgage-backed securities of $30.4 million and commercial mortgage-backed securities of $11.3 million for which no recent trade activity was observed for purposes of determining observable inputs;

• Municipal securities of $21.5 million and loans and other receivables of $20.1 million due to a lower number of contributors for certain vendor quotes supporting classification within Level 2; and

• Corporate debt securities of $7.4 million and investments at fair value of $74.7 million due to a lack of observable market transactions.

During the year ended December 31, 2015, transfers of assets of $85.8 million from Level 3 to Level 2 are attributed to:

• Non-agency residential mortgage-backed securities of $16.3 million and commercial mortgage-backed securities of $6.3 million for which market trades were observed in the year for either identical or similar securities;

• CDOs and CLOs of $34.9 million and loans and other receivables of $4.7 million due to a greater number of contributors for certain vendor quotes supporting classification into Level 2; and

• Investments at fair value of $15.8 million and corporate equity securities of $7.7 million due to an increase in observable market transactions.

During the year ended December 31, 2015, there were transfers of other secured financings of $51.6 million from Level 3 to Level 2 due to an increase in observable inputs in the valuation.

Net gains on Level 3 assets were $455.5 million and net gains on Level 3 liabilities were $7.6 million for the year ended December 31, 2015. Net gains on Level 3 assets were primarily due to increased valuations of our investment in FXCM and increase in valuation of certain investments at fair value and corporate equity securities partially offset by decreased valuations of CDOs and CLOs, certain loans and other receivables and residential and commercial mortgage-backed securities. Net gains on Level 3 liabilities were primarily due to increased valuations of certain net derivatives.

Quantitative Information about Significant Unobservable Inputs used in Level 3 Fair Value Measurements

The tables below present information on the valuation techniques, significant unobservable inputs and their ranges for our financial assets and liabilities, subject to threshold levels related to the market value of the positions held, measured at fair value on a recurring basis with a significant Level 3 balance. The range of unobservable inputs could differ significantly across different firms given the range of products across different firms in the financial services sector. The inputs are not representative of the inputs that could have been used in the valuation of any one financial instrument (i.e., the input used for valuing one financial instrument within a particular class of financial instruments may not be appropriate for valuing other financial instruments within that given class). Additionally, the ranges of inputs presented below should not be construed to represent uncertainty regarding the fair values of our financial instruments; rather the range of inputs is reflective of the differences in the underlying characteristics of the financial instruments in each category.

For certain categories, we have provided a weighted average of the inputs allocated based on the fair values of the financial instruments comprising the category. We do not believe that the range or weighted average of the inputs is indicative of the reasonableness of uncertainty of our Level 3 fair values. The range and weighted average are driven by the individual financial instruments within each category and their relative distribution in the population. The disclosed inputs when compared with the inputs as disclosed in other periods should not be expected to necessarily be indicative of changes in our estimates of unobservable inputs for a particular financial instrument as the population of financial instruments comprising the category will vary from period to period based on purchases and sales of financial instruments during the period as well as transfers into and out of Level 3 each period.

(a) Earnings before interest, taxes, depreciation and amortization (“EBITDA”).

The fair values of certain Level 3 assets and liabilities that were determined based on third-party pricing information, unadjusted past transaction prices, reported net asset value or a percentage of the reported enterprise fair value are excluded from the above tables. At December 31, 2017 and 2016, asset exclusions consisted of $228.6 million and $325.0 million, respectively, primarily comprised of investments at fair value, private equity securities, CDOs and CLOs, municipal securities, non-exchange traded securities and loans and other receivables. At December 31, 2017 and 2016, liability exclusions consisted of $4.2 million and $1.6 million, respectively, of other secured financings, commercial mortgage-backed securities, loans and corporate debt and equity securities.

Sensitivity of Fair Values to Changes in Significant Unobservable Inputs

For recurring fair value measurements categorized within Level 3 of the fair value hierarchy, the sensitivity of the fair value measurement to changes in significant unobservable inputs and interrelationships between those unobservable inputs (if any) are described below:

• Non-exchange traded securities and equity swaps using comparable pricing valuation techniques. A significant increase (decrease) in the comparable asset and underlying stock price in isolation would result in a significantly higher (lower) fair value measurement.

• Corporate debt securities using a convertible bond model. A significant increase (decrease) in the bond discount rate/yield would result in a significantly lower (higher) fair value measurement. A significant increase (decrease) in volatility would result in a significantly higher (lower) fair value measurement.

• Non-exchange traded securities, corporate debt securities, loans and other receivables, unfunded commitments, credit default swaps, interest rate swaps, total return swaps, other asset-backed securities and private equity securities using a market approach valuation technique. A significant increase (decrease) in the EBITDA or other multiples in isolation would result in a significantly higher (lower) fair value measurement. A significant increase (decrease) in the discount rate/yield of a loan and other receivable or certain derivatives would result in a significantly lower (higher) fair value measurement. A significant increase (decrease) in the transaction level of a private equity security, corporate debt security or loan and other receivable would result in a significantly higher (lower) fair value measurement. A significant increase (decrease) in the underlying stock price of the non-exchange traded securities would result in a significantly higher (lower) fair value measurement. A significant increase (decrease) in the credit spread of certain derivatives would result in a significantly lower (higher) fair value measurement. A significant increase (decrease) in the price of the private equity securities, non-exchange traded securities, corporate debt securities, unfunded commitments, total return swaps, other asset-backed securities or loans and other receivables would result in a significantly higher (lower) fair value measurement. A significant increase (decrease) in the estimated recovery rates of the cash flow outcomes underlying the corporate debt securities and loans and other receivables would result in a significantly higher (lower) fair value measurement.

• Loans and other receivables, CDOs and CLOs, commercial mortgage-backed securities and other asset-backed securities using scenario analysis. A significant increase (decrease) in the possible recovery rates of the cash flow outcomes underlying the investment would result in a significantly higher (lower) fair value measurement for the financial instrument. A significant increase (decrease) in the price of the commercial mortgage-backed securities would result in a significantly higher (lower) fair value measurement.

• CDOs and CLOs, residential and commercial mortgage-backed securities, other asset-backed securities and variable funding notes using a discounted cash flow valuation technique. A significant increase (decrease) in isolation in the constant default rate, loss severity or cumulative loss rate would result in a significantly lower (higher) fair value measurement. The impact of changes in the constant prepayment rate and duration would have differing impacts depending on the capital structure and type of security. A significant increase (decrease) in the discount rate/security yield would result in a significantly lower (higher) fair value measurement.

• Derivative equity options using an option model. A significant increase (decrease) in volatility would result in a significantly higher (lower) fair value measurement.

• Derivative equity options using a default rate model. A significant increase (decrease) in default probability would result in a significantly lower (higher) fair value measurement.

• Non-exchange traded securities and loans and other receivables using a present value model. A significant increase (decrease) in average silver production would result in a significantly higher (lower) fair value measurement.

• FXCM term loan using a discounted cash flow valuation technique. A significant increase (decrease) in term based on the time to pay off the loan would result in a higher (lower) fair value measurement. 

Fair Value Option Election

We have elected the fair value option for all loans and loan commitments made by Jefferies capital markets businesses. These loans and loan commitments include loans entered into by Jefferies Investment Banking division in connection with client bridge financing and loan syndications, loans purchased by Jefferies leveraged credit trading desk as part of its bank loan trading activities and mortgage and consumer loan commitments, purchases and fundings in connection with mortgage-and other asset-backed securitization activities. Loans and loan commitments originated or purchased by Jefferies leveraged credit and mortgage-backed businesses are managed on a fair value basis. Loans are included in Trading assets and loan commitments are included in Trading liabilities. The fair value option election is not applied to loans made to affiliate entities as such loans are entered into as part of ongoing, strategic business ventures. Loans to affiliate entities are included in Loans to and investments in associated companies in the Consolidated Statements of Financial Condition and are accounted for on an amortized cost basis. Jefferies has also elected the fair value option for certain of its structured notes which are managed by Jefferies capital markets business and are included in Long-term debt and Short-term borrowings in the Consolidated Statements of Financial Condition. Jefferies has elected the fair value option for certain financial instruments held by its subsidiaries as the investments are risk managed on a fair value basis. The fair value option has also been elected for certain secured financings that arise in connection with Jefferies securitization activities and other structured financings. Other secured financings, receivables from brokers, dealers and clearing organizations, receivables from customers of securities operations, payables to brokers, dealers and clearing organizations and payables to customers of securities operations, are accounted for at cost plus accrued interest rather than at fair value; however, the recorded amounts approximate fair value due to their liquid or short-term nature.

The following is a summary of Jefferies gains (losses) due to changes in instrument specific credit risk on loans, other receivables and debt instruments and gains (losses) due to other changes in fair value on long-term debt and short-term borrowings measured at fair value under the fair value option for the years ended December 31, 2017, 2016 and 2015 (in thousands):

The following is a summary of the amount by which contractual principal exceeds fair value for loans and other receivables and long-term debt measured at fair value under the fair value option (in thousands):

	December 31, 2017		December 31, 2016
Financial instruments owned:
Loans and other receivables (1)	$	752,076	$	1,325,938
Loans and other receivables on nonaccrual status and/or greater than 90 days past due (1) (2)	$	159,462	$	205,746
Long-term debt	$	32,839	$	20,202

(1) Interest income is recognized separately from other changes in fair value and is included within Interest income in the Consolidated Statements of Operations.

(2) Amounts include all loans and other receivables greater than 90 or more days past due by which contractual principal exceeds fair value of $38.7 million and $64.6 million at December 31, 2017 and 2016, respectively.

The aggregate fair value of Jefferies loans and other receivables on nonaccrual status and/or greater than 90 days or more past due, was $55.1 million and $29.8 million at December 31, 2017 and 2016, respectively, which includes loans and other receivables greater than 90 days past due of $37.4 million and $18.9 million at December 31, 2017 and 2016, respectively.

Jefferies had elected the fair value option for its investment in KCG Holdings, Inc. ("KCG"). The change in the fair value of this investment was $93.4 million, $19.6 million and $49.1 million for 2017, 2016 and 2015, respectively. Jefferies investment in KCG was sold in July 2017. Additionally, in connection with a KCG shares and warrants exchange transaction, Jefferies earned advisory fees of $2.9 million during the year ended December 31, 2016. Jefferies has also separately entered into securities lending transactions with KCG in the normal course of its capital markets activities. The balances of Securities borrowed and Securities loaned were $9.2 million and $9.2 million, respectively, December 31, 2016.

As of December 31, 2017 and 2016, we owned approximately 46.6 million common shares of HRG, representing approximately 23% of HRG’s outstanding common shares, which are accounted for under the fair value option. The shares are included in our Consolidated Statements of Financial Condition at fair value of $789.9 million and $725.1 million at December 31, 2017 and 2016, respectively.  The shares were acquired at an aggregate cost of $475.6 million. The change in the fair value of our investment in HRG was $64.8 million, $93.2 million and $(28.0) millionduring the years ended December 31, 2017, 2016 and 2015, respectively. As reported in its Form 10-K for its fiscal years ended September 30, 2017, 2016 and 2015, HRG's revenues were $5,008.5 million, $5,048.6 million and $4,753.8 million, respectively; net income (loss) from continuing operations was $102.9 million, $144.2 million and $(219.7) million, respectively; net income (loss) was $273.2 million, $(33.9) million and $(512.4) million, respectively; and net income (loss) attributable to HRG was $106.0 million, $(198.8) million and $(556.8) million, respectively. We currently have two directors on HRG’s board, including our Chairman who serves as HRG's Chairman and CEO. 

We believe accounting for these investments at fair value better reflects the economics of these investments, and quoted market prices for these investments provides an objectively determined fair value at each balance sheet date. Our investment in HomeFed, which is a publicly traded company, is accounted for under the equity method of accounting rather than the fair value option method. HomeFed’s common stock is not listed on any stock exchange, and price information for the common stock is not regularly quoted on any automated quotation system. It is traded in the over-the-counter market with high and low bid prices published by the NASD OTC Bulletin Board Service; however, trading volume is minimal. For these reasons, we did not elect the fair value option for HomeFed.

Financial Instruments Not Measured at Fair Value

Certain of our financial instruments are not carried at fair value but are recorded at amounts that approximate fair value due to their liquid or short-term nature and generally negligible credit risk. These financial assets include Cash and cash equivalents and Cash and securities segregated and on deposit for regulatory purposes or deposited with clearing and depository organizations and would generally be presented in Level 1 of the fair value hierarchy. Cash and securities segregated and on deposit for regulatory purposes or deposited with clearing and depository organizations includes U.S. Treasury securities with a fair value of $99.7 million and $99.9 million at December 31, 2017 and 2016, respectively. See Note 26 for additional information related to financial instruments not measured at fair value.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

Off-Balance Sheet Risk

Jefferies has contractual commitments arising in the ordinary course of business for securities loaned or purchased under agreements to resell, repurchase agreements, future purchases and sales of foreign currencies, securities transactions on a when-issued basis and underwriting. Each of these financial instruments and activities contains varying degrees of off-balance sheet risk whereby the fair values of the securities underlying the financial instruments may be in excess of, or less than, the contract amount. The settlement of these transactions is not expected to have a material effect upon our consolidated financial statements.

Derivative Financial Instruments

Derivative activities are recorded at fair value in the Consolidated Statements of Financial Condition in Trading assets and Trading liabilities, net of cash paid or received under credit support agreements and on a net counterparty basis when a legally enforceable right to offset exists under a master netting agreement. Predominantly, Jefferies and our Leucadia Asset Management businesses may enter into derivative transactions to satisfy the needs of its clients and to manage its own exposure to market and credit risks resulting from trading activities. In addition, Jefferies applies hedge accounting to an interest rate swap that has been designated as a fair value hedge of the changes in fair value due to the benchmark interest rate for certain fixed rate senior long-term debt. See Notes 4 and 24 for additional disclosures about derivative financial instruments.

Derivatives are subject to various risks similar to other financial instruments, including market, credit and operational risk. The risks of derivatives should not be viewed in isolation, but rather should be considered on an aggregate basis along with our other trading-related activities. Jefferies manages the risks associated with derivatives on an aggregate basis along with the risks associated with proprietary trading as part of its firm wide risk management policies.

In connection with Jefferies derivative activities, Jefferies may enter into International Swaps and Derivative Association, Inc. (“ISDA”) master netting agreements or similar agreements with counterparties. See Note 11 for additional information with respect to financial statement offsetting.

The following tables present the fair value and related number of derivative contracts categorized by type of derivative contract as reflected in the Consolidated Statements of Financial Condition at December 31, 2017 and 2016. The fair value of assets/liabilities represents our receivable/payable for derivative financial instruments, gross of counterparty netting and cash collateral received and pledged. The following tables also provide information regarding: 1) the extent to which, under enforceable master netting arrangements, such balances are presented net in our Consolidated Statements of Financial Condition as appropriate under GAAP and 2) the extent to which other rights of setoff associated with these arrangements exist and could have an effect on our financial position (in thousands, except contract amounts):

The net gains (losses) on derivative contracts in the table above are one of a number of activities comprising Jefferies business activities and are before consideration of economic hedging transactions, which generally offset the net gains (losses) included above. Jefferies substantially mitigates its exposure to market risk on its cash instruments through derivative contracts, which generally provide offsetting revenues, and Jefferies manages the risk associated with these contracts in the context of its overall risk management framework.

Single name credit default swaps	122.4		261.2		$	383.6

Contingent Features

Certain of Jefferies derivative instruments contain provisions that require their debt to maintain an investment grade credit rating from each of the major credit rating agencies. If Jefferies debt were to fall below investment grade, it would be in violation of these provisions and the counterparties to the derivative instruments could request immediate payment or demand immediate and ongoing full overnight collateralization on Jefferies derivative instruments in liability positions. The aggregate fair value of all derivative instruments with such credit-risk-related contingent features that are in a liability position at December 31, 2017 and 2016 is $95.1 million and $70.6 million, respectively, for which Jefferies has posted collateral of $80.8 million and $44.4 million, respectively, in the normal course of business. If the credit-risk-related contingent features underlying these agreements were triggered on December 31, 2017 and 2016, Jefferies would have been required to post an additional $14.3 million and $26.1 million, respectively, of collateral to its counterparties.

Other Derivatives

National Beef uses futures contracts in order to reduce its exposure associated with entering into firm commitments to purchase live cattle at prices determined prior to the delivery of the cattle as well as firm commitments to sell certain beef products at sales prices determined prior to shipment. National Beef accounts for the futures contracts at fair value. Firm commitments for sales are treated as normal sales and therefore not marked to market. Certain firm commitments to purchase cattle, are marked to market when a price has been agreed upon, otherwise they are treated as normal purchases and, therefore, not marked to market. The gains and losses associated with the change in fair value of the futures contracts and offsetting gains and losses associated with changes in the market value of certain of the firm purchase commitments are recorded to Beef processing services revenue and Cost of sales in the period of change.

Vitesse uses swaps and call and put options in order to reduce exposure to future oil price fluctuations. Vitesse accounts for the derivative instruments at fair value. The gains and losses associated with the change in fair value of the derivatives are recorded in Other revenues.

Collateralized Transactions [Abstract]

Collateralized Transactions

Collateralized Transactions

Jefferies enters into secured borrowing and lending arrangements to obtain collateral necessary to effect settlement, finance inventory positions, meet customer needs or re-lend as part of dealer operations. Jefferies monitors the fair value of the securities loaned and borrowed on a daily basis as compared with the related payable or receivable, and requests additional collateral or returns excess collateral, as appropriate. Jefferies pledges financial instruments as collateral under repurchase agreements, securities lending agreements and other secured arrangements, including clearing arrangements. Jefferies agreements with counterparties generally contain contractual provisions allowing the counterparty the right to sell or repledge the collateral. Pledged securities owned that can be sold or repledged by the counterparty are included in Financial instruments owned and noted parenthetically as Securities pledged on our Consolidated Statements of Financial Condition.

The following tables set forth the carrying value of securities lending arrangements and repurchase agreements by class of collateral pledged and remaining contractual maturity (in thousands):

Jefferies receives securities as collateral under resale agreements, securities borrowing transactions and customer margin loans.  Jefferies also receives securities as collateral in connection with securities-for-securities transactions in which it is the lender of securities. In many instances, Jefferies is permitted by contract to rehypothecate the securities received as collateral. These securities may be used to secure repurchase agreements, enter into securities lending transactions, satisfy margin requirements on derivative transactions or cover short positions. At December 31, 2017 and 2016, the approximate fair value of securities received as collateral by Jefferies that may be sold or repledged was $27.1 billion and $25.5 billion, respectively. A substantial portion of these securities have been sold or repledged.

Securitization Activities

Securitization Activities [Abstract]

Securitization Activities

Securitization Activities

Jefferies engages in securitization activities related to corporate loans, commercial mortgage loans, consumer loans and mortgage-backed and other asset-backed securities. In securitization transactions, Jefferies transfers assets to special purpose entities ("SPEs") and acts as the placement or structuring agent for the beneficial interests sold to investors by the SPE. A significant portion of the securitization transactions are securitization of assets issued or guaranteed by U.S. government agencies. These SPEs generally meet the criteria of VIEs; however, the SPEs are generally not consolidated as Jefferies is not considered the primary beneficiary for these SPEs. 

Jefferies accounts for securitization transactions as sales provided it has relinquished control over the transferred assets. Transferred assets are carried at fair value with unrealized gains and losses reflected in Principal transactions revenues in the Consolidated Statements of Operations prior to the identification and isolation for securitization. Subsequently, revenues recognized upon securitization are reflected as net underwriting revenues. Jefferies generally receives cash proceeds in connection with the transfer of assets to an SPE. Jefferies may, however, have continuing involvement with the transferred assets, which is limited to retaining one or more tranches of the securitization (primarily senior and subordinated debt securities in the form of mortgage- and other asset-backed securities or CLOs), which are included in Trading assets and are generally initially categorized as Level 2 within the fair value hierarchy. Jefferies applies fair value accounting to the securities. 

The following table presents activity related to Jefferies securitizations that were accounted for as sales in which it had continuing involvement during the years ended December 31, 2017, 2016 and 2015 (in millions):

	2017		2016		2015
Transferred assets	$	4,552.9	$	5,786.0	$	5,770.5
Proceeds on new securitizations	4,594.5		5,809.0		5,811.3
Cash flows received on retained interests	28.7		28.2		31.2

Jefferies has no explicit or implicit arrangements to provide additional financial support to these SPEs, has no liabilities related to these SPEs and has no outstanding derivative contracts executed in connection with these securitizations at December 31, 2017 and 2016.

The following table summarizes Jefferies retained interests in SPEs where it transferred assets and has continuing involvement and received sale accounting treatment (in millions):

	December 31, 2017				December 31, 2016
Securitization Type	Total Assets		Retained Interests		Total Assets		Retained Interests
U.S. government agency residential mortgage-backed securities	$	6,383.5	$	28.2	$	7,584.9	$	31.0
U.S. government agency commercial mortgage-backed securities	2,075.7		81.4		1,806.3		29.6
CLOs	3,957.8		20.3		4,102.2		37.0
Consumer and other loans	247.6		47.8		395.7		25.3

Total assets represent the unpaid principal amount of assets in the SPEs in which Jefferies has continuing involvement and are presented solely to provide information regarding the size of the transactions and the size of the underlying assets supporting its retained interests, and are not considered representative of the risk of potential loss. Assets retained in connection with a securitization transaction represent the fair value of the securities of one or more tranches issued by an SPE, including senior and subordinated tranches. Jefferies risk of loss is limited to this fair value amount which is included in total Trading assets in our Consolidated Statements of Financial Condition.

Although not obligated, in connection with secondary market-making activities Jefferies may make a market in the securities issued by these SPEs. In these market-making transactions, Jefferies buys these securities from and sells these securities to investors.  Securities purchased through these market-making activities are not considered to be continuing involvement in these SPEs. To the extent Jefferies purchased securities through these market-making activities and Jefferies is not deemed to be the primary beneficiary of the VIE, these securities are included in agency and non-agency mortgage- and asset-backed securitizations in the nonconsolidated VIEs section presented in Note 9.

Foursight Capital also utilized SPEs to securitize automobile loans receivable. These SPEs are VIEs and our subsidiary is the primary beneficiary; the related assets and the secured borrowings are recognized in the Consolidated Statements of Financial Condition. These secured borrowings do not have recourse to our subsidiary’s general credit. See Note 9 for further information on securitization activities and VIEs.

Variable Interest Entities

Variable Interest Entity, Measure of Activity [Abstract]

Variable Interest Entities

Variable Interest Entities

VIEs are entities in which equity investors lack the characteristics of a controlling financial interest. VIEs are consolidated by the primary beneficiary. The primary beneficiary is the party who has both the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and an obligation to absorb losses of the entity or a right to receive benefits from the entity that could potentially be significant to the entity.

Our variable interests in VIEs include debt and equity interests, equity interests in associated companies, commitments, guarantees and certain fees. Our involvement with VIEs arises primarily from the following activities, but also includes other activities discussed below:

• Purchases of securities in connection with our trading and secondary market-making activities;

• Retained interests held as a result of securitization activities, including the resecuritization of mortgage- and other asset-backed securities and the securitization of commercial mortgage, corporate and consumer loans;

• Acting as placement agent and/or underwriter in connection with client-sponsored securitizations;

• Financing of agency and non-agency mortgage- and other asset-backed securities;

• Real estate investments;

• Warehouse funding arrangements for client-sponsored consumer loan vehicles and CLOs through participation certificates and revolving loan and note commitments; and

• Loans to, investments in and fees from various investment vehicles.

We determine whether we are the primary beneficiary of a VIE upon our initial involvement with the VIE and we reassess whether we are the primary beneficiary of a VIE on an ongoing basis. Our determination of whether we are the primary beneficiary of a VIE is based upon the facts and circumstances for each VIE and requires significant judgment. Our considerations in determining the VIE’s most significant activities and whether we have power to direct those activities include, but are not limited to, the VIE’s purpose and design and the risks passed through to investors, the voting interests of the VIE, management, service and/or other agreements of the VIE, involvement in the VIE’s initial design and the existence of explicit or implicit financial guarantees. In situations where we have determined that the power over the VIE’s significant activities is shared, we assess whether we are the party with the power over the most significant activities. If we are the party with the power over the most significant activities, we meet the "power" criteria of the primary beneficiary. If we do not have the power over the most significant activities or we determine that decisions require consent of each sharing party, we do not meet the "power" criteria of the primary beneficiary.

We assess our variable interests in a VIE both individually and in aggregate to determine whether we have an obligation to absorb losses of or a right to receive benefits from the VIE that could potentially be significant to the VIE. The determination of whether our variable interest is significant to the VIE requires significant judgment. In determining the significance of our variable interest, we consider the terms, characteristics and size of the variable interests, the design and characteristics of the VIE, our involvement in the VIE and our market-making activities related to the variable interests.

Consolidated VIEs

The following table presents information about the assets and liabilities of our consolidated VIEs, which are presented in our Consolidated Statements of Financial Condition in the respective asset and liability categories (in millions). The assets and liabilities in the table below are presented prior to consolidation and thus a portion of these assets and liabilities are eliminated in consolidation.

(1) Securities purchased under agreements to resell represent an amount due under a collateralized transaction on a related consolidated entity, which is eliminated in consolidation.

(2) Approximately $44.1 million and $57.6 million of the secured financing represents an amount held by Jefferies in inventory and eliminated in consolidation at December 31, 2017 and 2016, respectively.

(3) Includes $32.0 million and $20.0 million at December 31, 2017 and 2016, respectively, of intercompany payables that are eliminated in consolidation.

Securitization Vehicles.  Jefferies is the primary beneficiary of mortgage-backed financing vehicles to which Jefferies sells agency and non-agency residential and commercial mortgage loans and mortgage-backed securities pursuant to the terms of a master repurchase agreement. Jefferies manages the assets within these vehicles. Jefferies variable interests in these vehicles consist of its collateral margin maintenance obligations under the master repurchase agreement and retained interests in securities issued. The assets of these VIEs consist of reverse repurchase agreements, which are available for the benefit of the vehicle’s debt holders. The creditors of these VIEs do not have recourse to Jefferies general credit and each such VIE’s assets are not available to satisfy any other debt.

Jefferies is also the primary beneficiary of securitization vehicles associated with their financing of consumer and small business loans. In the creation of the securitization vehicles, Jefferies was involved in the decisions made during the establishment and design of the entities and holds variable interests consisting of the securities retained that could potentially be significant. The assets of the VIEs consist of the small business loans and term loans backed by consumer installment receivables, which are available for the benefit of the vehicles' beneficial interest holders. The creditors of the VIEs do not have recourse to Jefferies general credit and the assets of the VIEs are not available to satisfy any other debt.

At December 31, 2017 and 2016, Foursight Capital is the primary beneficiary of SPEs it utilized to securitize automobile loans receivable. Foursight Capital acts as the servicer for which it receives a fee, and owns an equity interest in the SPEs. The notes issued by the SPEs are secured solely by the assets of the SPEs and do not have recourse to Foursight Capital’s general credit and the assets of the VIEs are not available to satisfy any other debt. During the year ended December 31, 2017, a pool of automobile loan receivables aggregating $186.5 million was securitized by Foursight Capital in connection with a secured borrowing offering. The majority of the proceeds from issuance of the secured borrowing were used to pay down Foursight Capital’s two credit facilities.

Real Estate Investment Vehicles. At December 31, 2016, 54 Madison, which we consolidated as a result of our control of the 54 Madison investment committee, had real estate investments in which it is the primary beneficiary. 54 Madison was involved in the decisions made during the establishment and design of the investment entities. 54 Madison's variable interests consisted of its investment in and management of the assets within these entities. The assets of these VIEs consisted primarily of financing note receivables and investments in associated companies, which were available for the benefit of the VIEs' debt holders. The debt holders of these VIEs had recourse to 54 Madison's general credit and the assets of the VIEs were not available to satisfy any other debt. As a result of the sale of our interest in the general partnership during 2017, 54 Madison has been deconsolidated and is reflected in Loans to and investments in associated companies at December 31, 2017.

Nonconsolidated VIEs

The following tables present information about our variable interests in nonconsolidated VIEs (in millions):

	Financial Statement Carrying Amount				Maximum Exposure to Loss		VIE Assets
	Assets		Liabilities
December 31, 2017
CLOs	$	168.1	$	8.9	$	1,030.4	$	5,364.3
Consumer loan vehicles	254.8		—		759.8		2,322.7
Related party private equity vehicles	23.7		—		45.4		75.0
Other private investment vehicles	133.0		—		142.0		4,624.9
Total	$	579.6	$	8.9	$	1,977.6	$	12,386.9
December 31, 2016
CLOs	$	264.7	$	4.8	$	930.0	$	4,472.9
Consumer loan vehicles	90.3		—		219.6		985.5
Related party private equity vehicles	37.6		—		63.6		155.6
Real estate investment vehicles	90.3		—		101.8		85.6
Other private investment vehicles	84.0		—		95.8		4,529.7
Total	$	566.9	$	4.8	$	1,410.8	$	10,229.3

Our maximum exposure to loss often differs from the carrying value of the variable interests. The maximum exposure to loss is dependent on the nature of the variable interests in the VIEs and is limited to the notional amounts of certain loan and equity commitments and guarantees. Our maximum exposure to loss does not include the offsetting benefit of any financial instruments that may be utilized to hedge the risks associated with its variable interests and is not reduced by the amount of collateral held as part of a transaction with a VIE.

Collateralized Loan Obligations.  Assets collateralizing the CLOs include bank loans, participation interests and sub-investment grade and senior secured U.S. loans. Jefferies underwrites securities issued in CLO transactions on behalf of sponsors and provides advisory services to the sponsors. Jefferies may also sell corporate loans to the CLOs. Jefferies variable interests in connection with CLOs where it has been involved in providing underwriting and/or advisory services consist of the following:

• Forward sale agreements whereby Jefferies commits to sell, at a fixed price, corporate loans and ownership interests in an entity holding such corporate loans to CLOs;

• Warehouse funding arrangements in the form of participation interests in corporate loans held by CLOs and commitments to fund such participation interests;

• Trading positions in securities issued in a CLO transaction;

• Investments in variable funding notes issued by CLOs; and

• A guarantee to a CLO managed by Jefferies Finance, whereby Jefferies guarantees certain of the obligations of Jefferies Finance to the CLO.

Consumer Loan Vehicles. Jefferies provides financing and lending related services to certain client-sponsored VIEs in the form of revolving funding note agreements, revolving credit facilities and forward purchase agreements. The underlying assets, which are collateralizing the vehicles, are primarily composed of unsecured consumer and small business loans. In addition, Jefferies may provide structuring and advisory services and act as an underwriter or placement agent for securities issued by the vehicles.  Jefferies does not control the activities of these entities.

Related Party Private Equity Vehicles. Jefferies committed to invest equity in private equity funds (the "JCP Funds") managed by Jefferies Capital Partners, LLC (the "JCP Manager"). Additionally, Jefferies committed to invest equity in the general partners of the JCP Funds (the "JCP General Partners") and the JCP Manager. Jefferies variable interests in the JCP Funds, JCP General Partners and JCP Manager (collectively, the "JCP Entities") consist of equity interests that, in total, provide Jefferies with limited and general partner investment returns of the JCP Funds, a portion of the carried interest earned by the JCP General Partners and a portion of the management fees earned by the JCP Manager. Jefferies total equity commitment in the JCP Entities was $148.1 million, of which $126.3 million and $125.1 million has been funded as of December 31, 2017 and 2016, respectively. The carrying value of Jefferies equity investments in the JCP Entities was $23.7 million and $37.6 million at December 31, 2017 and 2016, respectively. Jefferies exposure to loss is limited to the total of its carrying value and unfunded equity commitment. The assets of the JCP Entities primarily consist of private equity and equity related investments.

Jefferies has also provided a guarantee of a portion of Energy Partners I, LP's obligations under a credit agreement (“Energy Partners Credit Agreement”). Energy Partners I, LP is a private equity fund owned and managed by certain of our employees. The maximum exposure to loss of the guarantee was $3.0 million as of December 31, 2016.  Energy Partners I, LP has assets consisting primarily of debt and equity investments. The Energy Partners Credit Agreement was terminated in April 2017.

Real Estate Investment Vehicles. 54 Madison has committed to invest $98.0 million in real estate investment vehicles, of which $86.5 million was funded as of December 31, 2016. 54 Madison's maximum exposure to loss was limited to its carrying value and unfunded equity commitment. 54 Madison was not the primary beneficiary of the investment vehicles as it did not have the power to control the most important activities of the VIEs. The assets of the VIEs consisted primarily of investments in real estate projects. As a result of the sale of our interest in the general partner during 2017, the 54 Madison fund has been deconsolidated and is reflected in Loans to and investments in associated companies at December 31, 2017.

Other Private Investment Vehicles.  The carrying amount of our equity investment was $133.0 million and $84.0 million at December 31, 2017 and 2016, respectively. Our unfunded equity commitment related to these investments totaled $9.1 million and $11.8 million at December 31, 2017 and 2016, respectively. Our exposure to loss is limited to the total of our carrying value and unfunded equity commitment. These private investment vehicles have assets primarily consisting of private and public equity investments, debt instruments and various oil and gas assets.

Mortgage- and Other Asset-Backed Securitization Vehicles.  In connection with Jefferies secondary trading and market-making activities, Jefferies buys and sells agency and non-agency mortgage-backed securities and other asset-backed securities, which are issued by third party securitization SPEs and are generally considered variable interests in VIEs. Securities issued by securitization SPEs are backed by residential mortgage loans, U.S. agency collateralized mortgage obligations, commercial mortgage loans, CDOs and CLOs and other consumer loans, such as installment receivables, auto loans and student loans. These securities are accounted for at fair value and included in Trading assets in our Consolidated Statements of Financial Condition. Jefferies has no other involvement with the related SPEs and therefore does not consolidate these entities.

Jefferies also engages in underwriting, placement and structuring activities for third-party-sponsored securitization trusts generally through agency (FNMA ("Fannie Mae"), Federal Home Loan Mortgage Corporation ("Freddie Mac") or GNMA ("Ginnie Mae")) or non-agency-sponsored SPEs and may purchase loans or mortgage-backed securities from third parties that are subsequently transferred into the securitization trusts. The securitizations are backed by residential and commercial mortgage, home equity and auto loans. Jefferies does not consolidate agency-sponsored securitizations as it does not have the power to direct the activities of the SPEs that most significantly impact their economic performance. Further, Jefferies is not the servicer of non-agency-sponsored securitizations and therefore does not have power to direct the most significant activities of the SPEs and accordingly, does not consolidate these entities. Jefferies may retain unsold senior and/or subordinated interests at the time of securitization in the form of securities issued by the SPEs.

Jefferies transfers existing securities, typically mortgage-backed securities, into resecuritization vehicles. These transactions in which debt securities are transferred to a VIE in exchange for new beneficial interests occur in connection with both agency and non-agency-sponsored VIEs. The consolidation analysis is largely dependent on Jefferies role and interest in the resecuritization trusts. Most resecuritizations in which Jefferies is involved are in connection with investors seeking securities with specific risk and return characteristics. As such, Jefferies has concluded that the decision-making power is shared between Jefferies and the investor(s), considering the joint efforts involved in structuring the trust and selecting the underlying assets as well as the level of security interests the investor(s) hold in the SPE; therefore, Jefferies does not consolidate the resecuritization VIEs.

At December 31, 2017 and 2016, Jefferies held $1,829.6 million and $1,002.2 million of agency mortgage-backed securities, respectively, and $253.2 million and $439.4 million of non-agency mortgage- and other asset-backed securities, respectively, as a result of its secondary trading and market-making activities, underwriting, placement and structuring activities and resecuritization activities. Jefferies maximum exposure to loss on these securities is limited to the carrying value of its investments in these securities. Mortgage- and other asset-backed securitization vehicles discussed within this section are not included in the above table containing information about Jefferies variable interests in nonconsolidated VIEs.

We also have a variable interest in a nonconsolidated VIE consisting of our equity interest in an associated company, Golden Queen. In addition, we have a variable interest in a nonconsolidated VIE consisting of our senior secured term loan receivable and equity interest in FXCM.  See Notes 4 and 10 for further discussion.

(1) Primarily classified in Investment banking revenues and Other revenues.

(2) On October 31, 2017, Jefferies sold all of its membership interests in Jefferies LoanCore for approximately $173.1 million.

(3) At December 31, 2017, 2016 and 2015, the balance reflects $30.5 million, $32.8 million and $33.7 million, respectively, related to a noncontrolling interest.

(4) At December 31, 2016, the balance reflects $95.3 million related to noncontrolling interests.

(5) As discussed further below, on November 30, 2017, we sold our interest in the general partner of the 54 Madison fund and as a result no longer control the 54 Madison investment committee. We retained two of the four seats on the investment committee and continue to have significant influence over the fund. We therefore deconsolidated the 54 Madison fund and account for our interest under the equity method of accounting.

(6) As discussed more fully in Note 4, in 2016, we amended the terms of our loan and associated rights with FXCM. Through the amendments, we converted our participation rights for a 50% voting interest in FXCM. Our term loan remains classified within Trading assets, at fair value.

Jefferies Finance

Jefferies Finance, a joint venture entity pursuant to an agreement with Massachusetts Mutual Life Insurance Company ("MassMutual"), is a commercial finance company whose primary focus is the origination and syndication of senior secured debt to middle market and growth companies in the form of term and revolving loans. Loans are originated primarily through the investment banking efforts of Jefferies. Jefferies Finance may also originate other debt products such as second lien term, bridge and mezzanine loans, as well as related equity co-investments. Jefferies Finance also purchases syndicated loans in the secondary market and acts as an investment advisor for various loan funds.

At December 31, 2017, Jefferies and MassMutual each had equity commitments to Jefferies Finance of $750.0 million. At December 31, 2017, approximately $636.2 million of Jefferies commitment was funded. The investment commitment is scheduled to expire on March 1, 2018 with automatic one year extensions absent a 60-day termination notice by either party.

In addition, Jefferies and MassMutual have entered into a Secured Revolving Credit Facility, to be funded equally, to support loan underwritings by Jefferies Finance, which bears interest based on the interest rates of the related Jefferies Finance underwritten loans and is secured by the underlying loans funded by the proceeds of the facility. The total Secured Revolving Credit Facility is for a total committed amount of $500.0 million at December 31, 2017 and 2016. Advances are shared equally between Jefferies and MassMutual. The facility is scheduled to mature on March 1, 2018 with automatic one year extensions absent a 60-day termination notice by either party. At December 31, 2017, none of Jefferies $250.0 million commitment was funded. Jefferies recognized interest income and unfunded commitment fees related to the facility of $3.9 million, $1.3 million and $2.5 million during 2017, 2016 and 2015, respectively.

Jefferies engages in debt capital markets transactions with Jefferies Finance related to the originations and syndications of loans by Jefferies Finance. In connection with such services, Jefferies earned fees of $327.9 million, $112.6 million and $122.7 million during 2017, 2016 and 2015, respectively, which are recognized in Investment banking revenues in the Consolidated Statements of Operations. In addition, Jefferies paid fees to Jefferies Finance in respect of certain loans originated by Jefferies Finance of $2.4 million, $0.5 million and $5.9 million during 2017, 2016 and 2015, respectively, which are recognized within Selling, general and other expenses in the Consolidated Statements of Operations.

During the years ended December 31, 2017, 2016 and 2015, Jefferies acted as a placement agent for CLOs managed by Jefferies Finance, for which Jefferies recognized fees of $6.1 million, $2.6 million and $6.2 million, respectively, which are included in Investment banking revenues in the Consolidated Statements of Operations. At December 31, 2017 and 2016, Jefferies held securities issued by CLOs managed by Jefferies Finance, which are included in Trading assets. At December 31, 2016, Jefferies provided a guarantee, whereby Jefferies is required to make certain payments to a CLO in the event Jefferies Finance was unable to meet its obligations to the CLO. The CLO was terminated in October 2017. Additionally, Jefferies has entered into participation agreements and derivative contracts with Jefferies Finance based upon certain securities issued by the CLO. Gains (losses) related to the derivative contracts were not material.

Jefferies acted as underwriter in connection with senior notes issued by Jefferies Finance, for which Jefferies recognized underwriting fees of $1.3 million during the year ended December 31, 2015, which are included in Investment banking revenues in the Consolidated Statements of Operations.

Under a service agreement, Jefferies charged Jefferies Finance $50.7 million, $46.1 million and $51.7 million for services provided during 2017, 2016 and 2015, respectively. At December 31, 2017, Jefferies had a receivable from Jefferies Finance, included within Other assets in the Consolidated Statement of Financial Condition of $34.6 million and a payable to Jefferies Finance, included in Payables, expense accruals and other liabilities in the Consolidated Statement of Financial Condition of $14.1 million. At December 31, 2016, Jefferies had a payable to Jefferies Finance, included in Payables, expense accruals and other liabilities in the Consolidated Statement of Financial Condition of $5.8 million.

Jefferies enters into OTC foreign exchange contracts with Jefferies Finance as to which, at December 31, 2017, we had $1.5 million included in Trading assets in our Consolidated Statements of Financial Condition.

Jefferies LoanCore

Jefferies LoanCore, a commercial real estate finance company and a joint venture with the Government of Singapore Investment Corporation, the Canada Pension Plan Investment Board and LoanCore, LLC, originates and purchases commercial real estate loans throughout the U.S. and Europe. On October 31, 2017, Jefferies sold all of its membership interests (which constituted a 48.5% voting interest) in Jefferies LoanCore for approximately $173.1 million, the estimated book value as of October 31, 2017. In addition, Jefferies may be entitled to additional cash consideration over the next five years in the event Jefferies LoanCore's yearly return on equity exceeds certain thresholds.

Jefferies LoanCore had entered into master repurchase agreements with Jefferies. During 2017, 2016 and 2015, Jefferies recognized interest income and fees related to these agreements of $0.6 million, $8.4 million and $10.7 million, respectively. In connection with such master repurchase agreements, at December 31, 2016, Jefferies had securities purchased with agreements to resell from Jefferies LoanCore of $68.1 million. Jefferies also enters into OTC foreign exchange contracts with Jefferies LoanCore. In connection with these contracts, Jefferies had $8.3 million at December 31, 2016 recorded in Payables, expense accruals and other liabilities in the Consolidated Statement of Financial Condition.

Berkadia

Berkadia is a commercial mortgage banking and servicing joint venture formed in 2009 with Berkshire Hathaway Inc. We and Berkshire Hathaway each contributed $217.2 million of equity capital to the joint venture and each have a 50% equity interest in Berkadia. Through December 31, 2017, cumulative cash distributions received by Leucadia from this investment aggregated $562.0 million. Berkadia originates commercial/multifamily real estate loans that are sold to U.S. government agencies, and originates and brokers commercial/multifamily mortgage loans which are not part of government agency programs. Berkadia is an investment sales advisor focused on the multifamily industry. Berkadia is a servicer of commercial real estate loans in the U.S., performing primary, master and special servicing functions for U.S. government agency programs, commercial mortgage-backed securities transactions, banks, insurance companies and other financial institutions.

Berkadia uses all of the proceeds from the commercial paper sales of an affiliate of Berkadia to fund new mortgage loans, servicer advances, investments and other working capital requirements. Repayment of the commercial paper is supported by a $1.5 billion surety policy issued by a Berkshire Hathaway insurance subsidiary and corporate guaranty, and we have agreed to reimburse Berkshire Hathaway for one-half of any losses incurred thereunder. As of December 31, 2017, the aggregate amount of commercial paper outstanding was $1.47 billion.

FXCM

As discussed more fully in Note 4, at December 31, 2017, Leucadia has a 50% voting interest in FXCM and a senior secured term loan to FXCM due January 2018. On September 1, 2016, we gained the ability to significantly influence FXCM through our seats on the board of directors. As a result, we classify our equity investment in FXCM in our Consolidated Statements of Financial Condition as Loans to and investments in associated companies. Our term loan remains classified within Trading assets, at fair value. We account for our equity interest in FXCM on a one month lag. We are amortizing our basis difference between the estimated fair value and the underlying book value of FXCM customer relationships, technology, trade name, leases and long-term debt over their respective useful lives.

Based on the February 2017 actions described further in Note 4, we evaluated in the first quarter of 2017 whether our equity method investment was fully recoverable. We engaged an independent valuation firm to assist management in estimating the fair value of FXCM. Our estimate of fair value was based on a discounted cash flow and comparable public company analysis. The result of our analysis indicated that the estimated fair value of our equity interest in FXCM was lower than our carrying value by $130.2 million. We concluded based on the regulatory actions, FXCM's restructuring plan described further in Note 4, investor perception and declines in the trading price of Global Brokerage's common shares and convertible debt, that the decline in fair value of our equity interest was other than temporary. As such, we impaired our equity investment in FXCM in the first quarter of 2017 by $130.2 million.

FXCM is considered a VIE and our term loan and equity interest are variable interests. We have determined that we are not the primary beneficiary of FXCM because we do not have the power to direct the activities that most significantly impact FXCM's performance. Therefore, we do not consolidate FXCM.

Garcadia

Garcadia is a joint venture between us and Garff Enterprises, Inc. ("Garff") that owns and operates 28 automobile dealerships comprised of domestic and foreign automobile makers. The Garcadia joint venture agreement specifies that we and Garff shall have equal board representation and equal votes on all matters affecting Garcadia, and that all operating cash flows from Garcadia will be allocated 65% to us and 35% to Garff, with the exception of one dealership from which we receive 83% of all operating cash flows and four other dealerships from which we receive 71% of all operating cash flows. Garcadia’s strategy is to acquire automobile dealerships in primary or secondary market locations meeting its specified return criteria. 

Linkem

We own approximately 42% of the common shares of Linkem, a fixed wireless broadband services provider in Italy. In addition, we own 5% convertible preferred stock, which is automatically convertible to common shares in 2020. If all of our convertible preferred stock was converted, it would increase our ownership to approximately 53% of Linkem’s common equity at December 31, 2017. We have approximately 48% of the total voting securities of Linkem. The excess of our investment in Linkem’s common shares over our share of underlying book value is being amortized to expense over 12 years.

HomeFed

At December 31, 2017, we own 10,852,123 shares of HomeFed’s common stock, representing approximately 70% of HomeFed’s outstanding common shares; however, we have contractually agreed to limit our voting rights such that we will not be able to vote more than 45% of HomeFed’s total voting securities voting on any matter, assuming all HomeFed shares not owned by us are voted. HomeFed develops and owns residential and mixed-use real estate properties. HomeFed is a public company traded on the NASD OTC Bulletin Board (Symbol: HOFD). As a result of a 1998 distribution to all of our shareholders, approximately 4.8% of HomeFed is beneficially owned by our Chairman at December 31, 2017. Three of our executives serve on the board of directors of HomeFed, including our Chairman who serves as HomeFed’s Chairman, and our President. Since we do not control HomeFed, our investment in HomeFed is accounted for under the equity method as an investment in an associated company.

Golden Queen Mining Company

During 2014 and 2015, we invested $83.0 million, net in cash in a limited liability company (Gauss LLC) to partner with the Clay family and Golden Queen Mining Co. Ltd., to jointly fund, develop and operate the Soledad Mountain gold and silver mine project. Previously 100% owned by Golden Queen Mining Co. Ltd., the project is a fully-permitted, open pit, heap leach gold and silver project located in Kern County, California, which commenced gold and silver production in March 2016. In exchange for a noncontrolling ownership interest in Gauss LLC, the Clay family contributed $34.5 million, net in cash. Gauss LLC invested both our and the Clay family’s net contributions totaling $117.5 million to the joint venture, Golden Queen, in exchange for a 50% ownership interest. Golden Queen Mining Co. Ltd. contributed the Soledad Mountain project to the joint venture in exchange for the other 50% interest.

As a result of our consolidating Gauss LLC, our Loans to and investments in associated companies reflects Gauss LLC’s net investment of $117.5 million in the joint venture, which includes both the amount we contributed and the amount contributed by the Clay family. The joint venture, Golden Queen, is considered a VIE as the voting rights of the investors are not proportional to their obligations to absorb the expected losses and their rights to receive the expected residual returns, given the provision of services to the joint venture by Golden Queen Mining Co. Ltd. Golden Queen Mining Co. Ltd. has entered into an agreement with the joint venture for the provision of executive officers, financial, managerial, administrative and other services, and office space and equipment. We have determined that we are not the primary beneficiary of the joint venture and are therefore not consolidating its results.

Our maximum exposure to loss as a result of our involvement with the joint venture is limited to our investment. The excess of Gauss LLC's investment in Golden Queen's underlying book value is being amortized to expense over the estimated life of mine gold and silver sales.

54 Madison

We own approximately 48.1% of 54 Madison, a fund that seeks long-term capital appreciation through investment in real estate development and similar projects. Prior to November 30, 2017, we consolidated 54 Madison as a result of our control of the 54 Madison investment committee. 54 Madison invests both in projects which they consolidate and projects where they have significant influence and utilize the equity method of accounting. Based on total committed capital of the 54 Madison fund, all projects of this fund have already been identified and launched. On November 30, 2017, we sold our interest in the general partner of the 54 Madison fund and as a result no longer control the 54 Madison investment committee. We retained two of the four seats on the 54 Madison investment committee and continue to have significant influence over the fund, including a number of protective rights such as the right to block material investments, divestitures and changes outside of agreed upon parameters. We therefore deconsolidated the 54 Madison fund on November 30, 2017 and account for our interest under the equity method of accounting. We account for our equity interest in the 54 Madison fund on a one quarter lag.

Offsetting [Abstract]

Financial Statement Offsetting

Financial Statement Offsetting

In connection with Jefferies derivative activities and securities financing activities, Jefferies may enter into master netting agreements and collateral arrangements with counterparties. Generally, transactions are executed under standard industry agreements, including, but not limited to: derivative transactions – ISDA master netting agreements; securities lending transactions – master securities lending agreements; and repurchase transactions – master repurchase agreements. A master agreement creates a single contract under which all transactions between two counterparties are executed allowing for trade aggregation and a single net payment obligation. Master agreements provide protection in bankruptcy in certain circumstances and, where legally enforceable, enable receivables and payables with the same counterparty to be settled or otherwise eliminated by applying amounts due to a counterparty against all or a portion of an amount due from the counterparty or a third party. 

Under Jefferies derivative ISDA master netting agreements, Jefferies typically will also execute credit support annexes, which provide for collateral, either in the form of cash or securities, to be posted by or paid to a counterparty based on the fair value of the derivative receivable or payable based on the rates and parameters established in the credit support annex. In the event of the counterparty’s default, provisions of the master agreement permit acceleration and termination of all outstanding transactions covered by the agreement such that a single amount is owed by, or to, the non-defaulting party. In addition, any collateral posted can be applied to the net obligations, with any excess returned; and the collateralized party has a right to liquidate the collateral. Any residual claim after netting is treated along with other unsecured claims in bankruptcy court.

The conditions supporting the legal right of offset may vary from one legal jurisdiction to another and the enforceability of master netting agreements and bankruptcy laws in certain countries or in certain industries is not free from doubt. The right of offset is dependent both on contract law under the governing arrangement and consistency with the bankruptcy laws of the jurisdiction where the counterparty is located. Industry legal opinions with respect to the enforceability of certain standard provisions in respective jurisdictions are relied upon as a part of managing credit risk. In cases where Jefferies has not determined an agreement to be enforceable, the related amounts are not offset. Master netting agreements are a critical component of Jefferies risk management processes as part of reducing counterparty credit risk and managing liquidity risk.

Jefferies is also a party to clearing agreements with various central clearing parties. Under these arrangements, the central clearing counterparty facilitates settlement between counterparties based on the net payable owed or receivable due and, with respect to daily settlement, cash is generally only required to be deposited to the extent of the net amount. In the event of default, a net termination amount is determined based on the market values of all outstanding positions and the clearing organization or clearing member provides for the liquidation and settlement of the net termination amount among all counterparties to the open contracts or transactions.

The following table provides information regarding derivative contracts, repurchase agreements and securities borrowing and lending arrangements that are recognized in the Consolidated Statements of Financial Condition and 1) the extent to which, under enforceable master netting arrangements, such balances are presented net in the Consolidated Statements of Financial Condition as appropriate under GAAP and 2) the extent to which other rights of setoff associated with these arrangements exist and could have an effect on our consolidated financial position.

(1) Under master netting agreements with our counterparties, we have the legal right of offset with a counterparty, which incorporates all of the counterparty’s outstanding rights and obligations under the arrangement. These balances reflect additional credit risk mitigation that is available by a counterparty in the event of a counterparty’s default, but which are not netted in the balance sheet because other provisions of GAAP are not met. Further, for derivative assets and liabilities, amounts netted include cash collateral paid or received.

(2) Includes securities received or paid under collateral arrangements with counterparties that could be liquidated in the event of a counterparty default and thus offset against a counterparty’s rights and obligations under the respective repurchase agreements or securities borrowing or lending arrangements.

(3) At December 31, 2017, amounts include $5,678.6 million of securities borrowing arrangements, for which we have received securities collateral of $5,516.7 million, and $1,084.4 million of repurchase agreements, for which we have pledged securities collateral of $1,115.9 million, which are subject to master netting agreements but we have not determined the agreements to be legally enforceable. At December 31, 2016, amounts include $6,337.5 million of securities borrowing arrangements, for which we have received securities collateral of $6,146.0 million, and $810.4 million of repurchase agreements, for which we have pledged securities collateral of $834.2 million, which are subject to master netting agreements but we have not determined the agreements to be legally enforceable.

Goodwill Impairment Testing

The quantitative goodwill impairment test is performed at our reporting unit level and consists of two steps. In the first step, the fair value of the reporting unit is compared with its carrying value, including goodwill and allocated intangible assets. If the fair value is in excess of the carrying value, the goodwill for the reporting unit is considered not to be impaired. If the fair value is less than the carrying value, then a second step is performed in order to measure the amount of the impairment loss, if any, which is based on comparing the implied fair value of the reporting unit’s goodwill to the carrying value of the reporting unit's goodwill. 

The estimated fair values are based on valuation techniques that we believe market participants would use, although the valuation process requires significant judgment and often involves the use of significant estimates and assumptions. The methodologies we utilize in estimating fair value include price-to-earnings and price-to-book multiples of comparable public companies, multiples of mergers and acquisitions of similar businesses, projected cash flows and/or market capitalization. In addition, as the fair values determined under the market approach represent a noncontrolling interest, we applied a control premium to arrive at the estimated fair value of our reporting units on a controlling basis. An independent valuation specialist was engaged to assist with the valuation process for Jefferies at August 1, 2017. The results of our annual impairment test related to Jefferies, National Beef and other operations indicated goodwill was not impaired.

Our senior note indentures contain covenants that restrict our ability to incur more Indebtedness or issue Preferred Stock of Subsidiaries unless, at the time of such incurrence or issuance, the Company meets a specified ratio of Consolidated Debt to Consolidated Tangible Net Worth, limit the ability of the Company and Material Subsidiaries to incur, in certain circumstances, Liens, limit the ability of Material Subsidiaries to incur Funded Debt in certain circumstances, and contain other terms and restrictions all as defined in the senior note indentures. We have the ability to incur substantial additional indebtedness or make distributions to our shareholders and still remain in compliance with these restrictions. If we are unable to meet the specified ratio, we would not be able to issue additional Indebtedness or Preferred Stock, but our inability to meet the applicable ratio would not result in a default under our senior note indentures. The senior note indentures do not restrict the payment of dividends.

Subsidiary Debt

During 2017, $20.2 million of Jefferies 3.875% Convertible Senior Debentures due 2029 (original principal amount of $345.0 million) were called. In November 2017, all of the remaining 3.875% Convertible Senior Debentures were called for optional redemption, with a redemption date of January 5, 2018, at a redemption price equal to 100% of the principal amount of the convertible debentures redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. All of these remaining convertible debentures were redeemed in January 2018.

During the year ended December 31, 2017, Jefferies issued structured notes with a total principal amount of approximately $329.9 million, net of retirements. Structured notes of $607.0 million and $248.9 million at December 31, 2017 and 2016, respectively, contain various interest rate payment terms and are accounted for at fair value, with changes in fair value resulting from a change in the instrument-specific credit risk presented in Accumulated other comprehensive income and changes in fair value resulting from non-credit components recognized in Principal transaction revenues.

In January 2018, Jefferies issued 4.15% senior notes with a principal amount of $1.0 billion, due 2030. In January 2017, Jefferies issued 4.85% senior notes with a principal amount of $750.0 million, due 2027.

In June 2017, National Beef entered into a Third Amended and Restated Credit Agreement (the "Debt Agreement"). The Debt Agreement matures in June 2022 and includes a $275.0 million reducing revolver loan and a $275.0 million revolving credit facility. The reducing revolver loan commitment decreases by $13.8 million on each annual anniversary of the Debt Agreement. The Debt Agreement is secured by a first priority lien on substantially all of the assets of National Beef and its subsidiaries and includes customary covenants including a single financial covenant that requires National Beef to maintain a minimum tangible net worth as defined in the Debt Agreement; at December 31, 2017, National Beef was in compliance with the covenants.

At December 31, 2017, National Beef’s outstanding debt under the Debt Agreement consisted of a reducing revolver loan with an outstanding balance of $120.0 million and $80.0 million drawn on the revolving credit facility. The reducing revolver loan and the revolving credit facility bear interest at the Base Rate or the LIBOR Rate (as defined in the Debt Agreement), plus a margin ranging from .75% to 2.75% depending upon certain financial ratios and the rate selected. At December 31, 2017, the interest rate on the outstanding reducing revolver loan was 3.3% and the interest rate on the outstanding revolving credit facility was 3.3%. 

Borrowings under the reducing revolver loan and the revolving credit facility are available for National Beef’s working capital requirements, capital expenditures and other general corporate purposes. Unused capacity under the revolving credit facility can also be used to issue letters of credit; letters of credit aggregating $13.9 million were outstanding at December 31, 2017. Amounts available under the revolving credit facility are subject to a borrowing base calculation primarily comprised of receivable and inventory balances; amounts available under the reducing revolver facility are constrained only by the annual reduction in the commitment amount. At December 31, 2017, after deducting outstanding amounts and issued letters of credit, $87.1 million of the unused revolving credit facility and $155.0 million of the reducing revolver commitment was available to National Beef.

54 Madison seeks long-term capital appreciation through real estate development and similar projects. Many of these development projects are funded through long-term debt at the project level. The debt holders do not have recourse to the Leucadia parent company. As discussed further in Note 10, due to the sale of our interest in the general partner of the 54 Madison fund, the 54 Madison fund and its long-term debt was deconsolidated during 2017.

At December 31, 2017, Foursight Capital’s credit facilities consisted of two warehouse credit commitments aggregating $225.0 million, which mature in March 2019 and July 2020. The 2019 credit facility bears interest based on the three-month LIBOR plus a credit spread fixed through its maturity and the 2020 credit facility bears interest based on the one-month LIBOR plus a credit spread fixed through its maturity. As a condition of the 2019 credit facility, Foursight Capital is obligated to maintain cash reserves in an amount equal to the quoted price of an interest rate cap sufficient to meet the hedging requirements of the credit commitment. The credit facilities are secured by first priority liens on auto loan receivables owed to Foursight Capital of approximately $200.5 million at December 31, 2017.

Mezzanine Equity

Redeemable Noncontrolling Interests

Redeemable noncontrolling interests primarily relate to National Beef and are held by its minority owners, USPB, NBPCo Holdings and the chief executive officer of National Beef. The holders of these interests share in the profits and losses of National Beef on a pro rata basis with us. However, the minority owners have the right to require us to purchase their interests under certain specified circumstances at fair value (put rights), and we also have the right to purchase their interests under certain specified circumstances at fair value (call rights). Holders of the put rights had from December 30, 2016 through January 29, 2017 to make an election that would require us to purchase up to one-third of their interests. The holders of the put rights did not make such election. The holders will again have the right to make an election that requires us to purchase up to one-third on December 30, 2018, and the remainder on December 30, 2021. In addition, USPB may elect to exercise their put rights following the termination of the cattle supply agreement, and the chief executive officer following the termination of his employment.

Our call rights with respect to USPB may be exercised following the termination of the cattle supply agreement or after USPB’s ownership interest is less than 20% of their interest held at the time we acquired National Beef. Our call rights with respect to other members may be exercised after the ten year anniversary of our acquisition of National Beef if such member’s ownership interest is less than 50% of the interest held at the time we acquired National Beef. Additionally, we may acquire the chief executive officer’s interest following the termination of his employment.

Redeemable noncontrolling interests in National Beef are reflected in the Consolidated Statements of Financial Condition at fair value. The following table rolls forward National Beef’s redeemable noncontrolling interests activity during the years ended December 31, 2017 and 2016 (in thousands):

	2017			2016
As of January 1,	$	321,962		$	189,358
Income allocated to redeemable noncontrolling interests	85,277			68,811
Distributions to redeemable noncontrolling interests	(90,048		)	(53,701		)
Increase in fair value of redeemable noncontrolling interests charged to additional paid-in capital	94,937			117,494
Balance, December 31,	$	412,128		$	321,962

At acquisition, we prepared a projection of future cash flows of National Beef, which was used along with other information to allocate the purchase price to National Beef’s individual assets and liabilities. At December 31, 2017, we calculated the fair value of the redeemable noncontrolling interests by updating our estimate of future cash flows. The projected future cash flows consider estimated revenue growth, cost of sales changes, capital expenditures and other unobservable inputs. However, the most significant unobservable inputs affecting the estimate of fair value are the discount rate (12.20%) and the terminal growth rate (2.00%) used to calculate the capitalization rate of the terminal value.

The table below is a sensitivity analysis which shows the fair value of the redeemable noncontrolling interests using the assumed discount and the terminal growth rates and fair values under different rate assumptions as of December 31, 2017 (dollars in millions):

		Discount Rates
Terminal Growth Rates		11.95%		12.20%		12.45%
1.75	%	$	417.6	$	407.6	$	398.1
2.00	%	$	422.4	$	412.1	$	402.3
2.25	%	$	427.5	$	416.9	$	406.8

The projection of future cash flows is updated with input from National Beef personnel. The estimate is reviewed by personnel at our corporate office as part of the normal process for the preparation of our quarterly and annual financial statements.

At December 31, 2017 and 2016, redeemable noncontrolling interests also includes other redeemable noncontrolling interests of $14.5 million and $14.8 million, respectively, primarily related to our oil and gas production and development businesses.

Mandatorily Redeemable Convertible Preferred Shares

In connection with our acquisition of Jefferies in March 2013, we issued a new series of 3.25% Cumulative Convertible Preferred Shares (“Preferred Shares”) ($125.0 million at mandatory redemption value) in exchange for Jefferies outstanding 3.25% Series A-1 Cumulative Convertible Preferred Stock. The Preferred Shares have a 3.25% annual, cumulative cash dividend and are currently convertible into 4,162,200 common shares, an effective conversion price of $30.03 per share. The holders of the Preferred Shares are also entitled to an additional quarterly payment in the event we declare and pay a dividend on our common stock in an amount greater than $0.0625 per common share per quarter. The additional quarterly payment would be paid to the holders of Preferred Shares on an as converted basis and on a per share basis would equal the quarterly dividend declared and paid to a holder of a share of common stock in excess of $0.0625 per share. In the third quarter of 2017, we increased our quarterly dividend from $0.0625 to $0.10 per common share. This increased the preferred stock dividend from $4.1 million for the year ended December 31, 2016 to $4.4 million for the year ended December 31, 2017. The Preferred Shares are callable beginning in 2023 at a price of $1,000 per share plus accrued interest and are mandatorily redeemable in 2038.

Share-based Compensation [Abstract]

Compensation Plans

Compensation Plans

Incentive Plan

Upon completion of our combination with Jefferies, we assumed its 2003 Incentive Compensation Plan, as Amended and Restated July 25, 2013 (the "Incentive Plan"). The Incentive Plan allows awards in the form of incentive stock options (within the meaning of Section 422 of the Internal Revenue Code), nonqualified stock options, stock appreciation rights, restricted stock, unrestricted stock, performance awards, restricted stock units ("RSUs"), dividend equivalents or other share-based awards.

RSUs give a participant the right to receive fully vested shares at the end of a specified deferral period allowing a participant to hold an interest tied to common stock on a tax deferred basis. Prior to settlement, RSUs carry no voting or dividend rights associated with the stock ownership, but dividend equivalents are accrued to the extent there are dividends declared on the underlying common shares as cash amounts or as deemed reinvestments in additional RSUs.

Restricted stock and RSUs may be granted to new employees as "sign-on" awards, to existing employees as "retention" awards and to certain executive officers as awards for multiple years. Sign-on and retention awards are generally subject to annual ratable vesting over a four-year service period and are amortized as compensation expense on a straight-line basis over the related four years. Restricted stock and RSUs are granted to certain senior executives with market, performance and service conditions. Market conditions are incorporated into the grant-date fair value of senior executive awards using a Monte Carlo valuation model. Compensation expense for awards with market conditions is recognized over the service period and is not reversed if the market condition is not met. Awards with performance conditions are amortized over the service period if it is determined that it is probable that the performance condition will be achieved. Awards granted to senior executives related to the 2015 fiscal year did not meet performance targets, and as a result, compensation expense has been adjusted to reflect the reduced number of shares that have vested.

The Deferred Compensation Plan (the “DCP”) has been implemented under the Incentive Plan. The DCP permits eligible executive officers and other employees to defer cash compensation, some or all of which may be deemed invested in stock units. A portion of the deferrals may also be directed to notional investments in a money market fund or certain of the employee investment opportunities. Stock units generally have been acquired at a discounted price, which encourages employee participation in the DCP and enhances long-term retention of equity interests by participants and aligns executive interests with those of shareholders.  Amounts recognized as compensation cost under the DCP have not been significant. The shares to be delivered in connection with DCP stock units and options are drawn from the Incentive Plan.

The Incentive Plan’s “evergreen” share reservation was terminated on March 21, 2014; the number of equity awards available under the Incentive Plan was set at 20,000,000. At December 31, 2017, 11,883,293 common shares remained available for new grants under the Incentive Plan. Shares issued pursuant to the DCP reduce the shares available under the Incentive Plan.

During 2017 and 2016, grants include approximately 89,000 and 108,000, respectively, of dividend equivalents declared on RSUs; the weighted-average grant date fair values of the dividend equivalents were approximately $21.03 and $13.53, respectively.

Senior Executive Compensation Plan

In February 2016, the Compensation Committee of our Board of Directors approved an executive compensation plan for our CEO and our President (together, our "Senior Executives") in respect of 2016 (the "2016 Plan") that is based on performance metrics achieved over a three-year period from 2016 through 2018. The Compensation Committee eliminated cash incentive bonuses for 2016 and 100% of each of our CEO and President's compensation beyond their base salaries is composed entirely of performance based RSUs that vest at the end of 2018 if certain performance criteria are met. Any vested RSUs will be subject to a post-vesting, three-year holding period such that no vested RSUs can be sold or transferred until the first quarter of 2022.

Performance-vesting of the award is based equally on the compound annual growth rates of Leucadia's Total Shareholder Return ("TSR"), which is measured from the December 31, 2015 stock price of $17.39, and Leucadia's Return on Tangible Deployable Equity ("ROTDE"), the annual, two- and three-year results of which is used to determine vesting. TSR is based on annualized rate of return reflecting price appreciation plus reinvestment of dividends and distributions to shareholders. ROTDE is net income adjusted for amortization of intangible assets divided by tangible book value at the beginning of year adjusted for intangible assets and deferred tax assets.

In January 2017, the Compensation Committee of our Board of Directors approved an executive compensation plan for our Senior Executives in respect of 2017 (the "2017 Plan") that is based on performance metrics achieved over a three-year period from 2017 through 2019. This executive compensation plan is identical to the 2016 Plan, described above, where cash incentive bonuses were eliminated. 100% of each of our CEO and President's compensation beyond their base salaries is composed entirely of performance based RSUs that will vest at the end of 2019 if certain performance criteria are met. Any vested RSUs are subject to a post-vesting, three-year holding period such that no vested RSUs can be sold or transferred until the first quarter of 2023. Performance-vesting of the award is based equally on the compound annual growth rates of Leucadia's TSR, which is measured from the December 30, 2016 stock price of $23.25, and Leucadia's ROTDE, the annual, two- and three-year results of which are used to determine vesting.

If Leucadia's TSR and ROTDE annual compound growth rates are less than 4%, our Senior Executives will not receive any incentive compensation. If Leucadia's TSR and ROTDE grow between 4% and 8% on a compounded basis over the three-year measurement period, each of our Senior Executives will be eligible to receive between 846,882 and 1,693,766 RSUs related to the 2016 Plan and 537,634 and 1,075,268 RSUs related to the 2017 Plan. If TSR and ROTDE growth rates are greater than 8%, our Senior Executives are eligible to receive up to 50% additional incentive compensation on a pro rata basis up to 12% growth rates. When determining whether RSUs will vest, the calculation will be weighted equally between TSR and ROTDE. If TSR growth was below minimum thresholds, but ROTDE growth was above minimum thresholds, our Senior Executives would still be eligible to receive some number of vested RSUs based on ROTDE growth. The TSR award contains a market condition and compensation expense is recognized over the service period and will not be reversed if the market condition is not met. The ROTDE award contains a performance condition and compensation expense is recognized over the service period if it is determined that it is probable that the performance condition will be achieved.

The following table details the activity in RSUs related to the senior executive compensation plan during the years ended December 31, 2017 and 2016 (in thousands, except per share amounts):

	Target Number of Shares	Weighted- Average Grant Date Fair Value
Balance at December 31, 2015	—	$	—
Grants	3,434	$	9.68
Forfeited	—	$	—
Balance at December 31, 2016	3,434	$	9.68
Grants	2,221	$	19.06
Forfeited	—	$	—
Balance at December 31, 2017	5,655	$	13.37

During 2017 and 2016, grants include approximately 70,000 and 47,000, respectively, of dividend equivalents declared on RSUs; the weighted-average grant date fair values of the dividend equivalents were approximately $21.04 and $13.63, respectively.

The Compensation Committee of the Leucadia Board of Directors approved an executive compensation plan effective January 1, 2018 that extends Leucadia’s current compensation plans for our Senior Executives for compensation years 2018, 2019 and 2020. For each Senior Executive, the Compensation Committee has targeted long-term compensation of $25.0 million per year under the plan with a target of $16.0 million in long-term equity in the form of RSUs and a target of $9.0 million long-term cash, subject to performance targets over the three-year measurement period for each compensation year. To receive targeted long-term equity, our Senior Executives will have to achieve 8% growth on an annual and multi-year compounded basis in Leucadia’s TSR and to receive targeted long-term cash, our Senior Executives will have to achieve 8% growth on an annual and multi-year compounded basis in Leucadia’s ROTDE. If TSR and ROTDE are less than 5%, our Senior Executives will receive no long-term compensation. If TSR and ROTDE growth rates are greater than 8%, our Senior Executives are eligible to receive up to 50% additional incentive compensation on a pro rata basis up to 12% growth rates.

Directors’ Plan

Upon completion of our combination with Jefferies, we also assumed the 1999 Directors' Stock Compensation Plan, as Amended and Restated July 25, 2013 (the "Directors' Plan"). Under the Directors’ Plan, we issue each nonemployee director of Leucadia $120,000 of restricted stock or RSUs each year. These grants are made on the date directors are elected or reelected at our annual shareholders’ meeting. These shares vest over three years from the date of grant and are expensed over the requisite service period.  At December 31, 2017, 321,026 common shares were issuable upon settlement of outstanding RSUs and 297,926 shares are available for future grants.

Other Compensation Plans

Other Stock-Based Plans. Historically, Jefferies also sponsored an Employee Stock Purchase Plan and an Employee Stock Ownership Plan, both of which were assumed by us in connection with the Jefferies acquisition. Amounts related to these plans have not been significant.

Prior to the acquisition of Jefferies, we had two share-based compensation plans: a fixed stock option plan and a senior executive warrant plan.

• 1999 Stock Option Plan. This plan provided for the issuance of stock options and stock appreciation rights to non-employee directors and certain employees at not less than the fair market value of the underlying stock at the date of grant. Options granted to employees under this plan were intended to qualify as incentive stock options to the extent permitted under the Internal Revenue Code and became exercisable in five equal annual installments starting one year from date of grant. Options granted to non-employee directors became exercisable in four equal annual installments starting one year from date of grant. No stock appreciation rights have been granted. In March 2014, we ceased issuing options and rights under our option plan. No shares remain available for future grants under this plan.

• Senior Executive Warrant Plan.  The warrants to purchase 2,000,000 common shares that were granted in 2011 to each of our then Chairman and then President expired unexercised during the first quarter of 2016. We had recorded share-based compensation expense related to this grant of warrants of $1.0 million for the year ended December 31, 2015. No shares remain available for future grants under this warrant plan.

At December 31, 2017 and 2016, 331,312 and 641,478, respectively, of our common shares were reserved for stock options.

A summary of activity with respect to our stock options during the years ended December 31, 2017, 2016 and 2015 is as follows (in thousands, except per share amounts):

	Common Shares Subject to Option		Weighted- Average Exercise Prices		Weighted- Average Remaining Contractual Term	Aggregate Intrinsic Value

Restricted Cash Awards. Jefferies provides compensation to new and existing employees in the form of loans and/or other cash awards which are subject to ratable vesting terms with service requirements. These awards are amortized to compensation expense over the relevant service period. At December 31, 2017, the remaining unamortized amount of these awards was $481.6 million and is included within Other assets in the Consolidated Statement of Financial Condition.

Stock-Based Compensation Expense

Compensation and benefits expense included $48.4 million, $33.6 million and $74.1 millionfor the years ended December 31, 2017, 2016 and 2015, respectively, for share-based compensation expense relating to grants made under our share-based compensation plans. Total compensation cost includes the amortization of sign-on, retention and senior executive awards, less forfeitures and clawbacks. The total tax benefit recognized in results of operations related to share-based compensation expenses was $17.3 million, $12.4 million and $27.3 millionfor the years ended December 31, 2017, 2016 and 2015, respectively. As of December 31, 2017, total unrecognized compensation cost related to nonvested share-based compensation plans was $68.0 million; this cost is expected to be recognized over a weighted-average period of 1.7 years.

The net tax detriment related to share-based compensation plans recognized in additional paid-in capital was $4.2 million and $5.9 millionduring the years ended December 31, 2016 and 2015, respectively.

At December 31, 2017, there were 1,142,000 shares of restricted stock outstanding with future service required, 5,687,000 RSUs outstanding with future service required (including target RSUs issuable under the senior executive compensation plan), 10,313,000 RSUs outstanding with no future service required and 887,000 shares issuable under other plans. Excluding shares issuable pursuant to outstanding stock options, the maximum potential increase to common shares outstanding resulting from these outstanding awards is 16,887,000.

Pension Plans and Postretirement Benefits

Pension Plans and Postretirement Benefits

U.S. Pension Plans

Pursuant to the agreement to sell one of our former subsidiaries, WilTel Communications Group, LLC, the responsibility for WilTel’s defined benefit pension plan was retained by us. All benefits under this plan were frozen as of October 30, 2005. Prior to the acquisition of Jefferies, Jefferies sponsored a defined benefit pension plan covering certain employees; benefits under that plan were frozen as of December 31, 2005.

Late in 2015, we launched a limited time voluntary lump sum offer to approximately 4,000 of the deferred vested participants of the WilTel plan. Approximately 2,400 participants accepted the lump sum offer and benefit payments totaling $110.7 million were paid out of plan assets. We also recorded a $40.7 million settlement charge in 2015 related to the participant acceptances.

A summary of activity with respect to both plans is as follows (in thousands):

	2017			2016
Change in projected benefit obligation:
Projected benefit obligation, beginning of year	$	205,405		$	207,025
Interest cost	8,119			8,464
Actuarial (gains) losses	6,644			(544		)
Benefits paid	(8,911		)	(9,540		)
Projected benefit obligation, end of year	$	211,257		$	205,405
Change in plan assets:
Fair value of plan assets, beginning of year	$	127,514		$	117,719
Actual return on plan assets	22,192			2,947
Employer contributions	12,417			19,100
Benefits paid	(8,911		)	(9,540		)
Administrative expenses	(2,406		)	(2,712		)
Fair value of plan assets, end of year	$	150,806		$	127,514
Funded status at end of year	$	(60,451	)	$	(77,891	)

As of December 31, 2017 and 2016, $51.3 million and $58.9 million, respectively, of the net amount recognized in the Consolidated Statements of Financial Condition was reflected as a charge to Accumulated other comprehensive income (substantially all of which were cumulative losses) and $60.5 million and $77.9 million, respectively, was reflected as accrued pension cost.

The following table summarizes the components of net periodic pension cost and other amounts recognized in other comprehensive income (loss) excluding taxes (in thousands):

	2017			2016			2015
Components of net periodic pension cost:
Interest cost	$	8,119		$	8,464		$	12,958
Expected return on plan assets	(7,689		)	(7,589		)	(10,581		)
Settlement charge	—			—			40,973
Actuarial losses	2,207			1,908			6,963
Net periodic pension cost	$	2,637		$	2,783		$	50,313
Amounts recognized in other comprehensive income (loss):
Net (gain) loss arising during the period	$	(5,453	)	$	6,811		$	(24,186	)
Settlement charge	—			—			(40,973		)
Amortization of net loss	(2,207		)	(1,908		)	(6,963		)
Total recognized in other comprehensive income (loss)	$	(7,660	)	$	4,903		$	(72,122	)
Net amount recognized in net periodic benefit cost and other comprehensive income (loss)	$	(5,023	)	$	7,686		$	(21,809	)

The amounts in Accumulated other comprehensive income at the end of each year have not yet been recognized as components of net periodic pension cost in the Consolidated Statements of Operations. The estimated net loss that will be amortized from accumulated other comprehensive income (loss) into net periodic benefit cost in 2018 is $2.5 million.

We expect to pay $8.9 million of employer contributions in 2018.

We use a December 31 measurement date for the WilTel plan and a November 30 date for the Jefferies plan. The assumptions used are as follows:

	2017		2016
WilTel Plan
Discount rate used to determine benefit obligation	3.51	%	3.85	%
Weighted-average assumptions used to determine net pension cost:
Discount rate	3.85	%	4.00	%
Expected long-term return on plan assets	7.00	%	7.00	%
Jefferies Plan
Discount rate used to determine benefit obligation	3.60	%	3.90	%
Weighted-average assumptions used to determine net pension cost:
Discount rate	3.90	%	4.10	%
Expected long-term return on plan assets	6.25	%	6.25	%

The following pension benefit payments are expected to be paid (in thousands):

2018	$	9,943
2019	9,915
2020	9,666
2021	9,577
2022	10,233
2023 – 2027	67,493

U.S. Plan Assets

The information below on the plan assets for the WilTel plan and the Jefferies plan is presented separately for the plans as the investments are managed independently. Cash equivalents are valued at cost, which approximates fair value and are categorized in Level 1 of the fair value hierarchy. The estimated fair values for securities measured using Level 1 inputs are determined using publicly quoted market prices in active markets for identical assets. Certain fixed income securities are measured using Level 2 inputs. Although these securities trade in brokered markets, the market for certain securities is sometimes inactive. Valuation inputs include benchmark yields, reported trades, broker dealer quotes, issuer spreads, two sided markets, benchmark securities, bids, offers, reference data, and industry and economic events. Neither plan had any assets classified within Level 3 of the fair value hierarchy.

WilTel Plan Assets.  At December 31, 2017 and 2016, the WilTel plan assets at fair value consisted of the following (in thousands):

			Fair Value Measurements Using
	Total		Level 1		Level 2
2017
Cash and cash equivalents	$	539	$	539	$	—
Growth Portfolio	65,625		—		65,625
Liability-Driven Investing Portfolio	31,693		—		31,693
Total	$	97,857	$	539	$	97,318
2016
Cash and cash equivalents	$	919	$	919	$	—
Growth Portfolio	51,852		—		51,852
Liability-Driven Investing Portfolio	24,751		—		24,751
Total	$	77,522	$	919	$	76,603

The current investment objectives are designed to close the funding gap while mitigating funded status volatility through a combination of liability hedging and investment returns. As plan funded status improves, the asset allocation will move along a predetermined, de-risking glide path that reallocates capital from growth assets to liability-hedging assets in order to reduce funded status volatility and lock in funded status gains. Plan assets are split into two separate portfolios, each with different asset mixes and objectives:

• The Growth Portfolio consists of global equities and high yield investments.

• The Liability-Driven Investing ("LDI") Portfolio consists of long duration credit bonds and a suite of long duration, Treasury-based instruments designed to provide capital-efficient interest rate exposure as well as target specific maturities. The objective of the LDI Portfolio is to seek to achieve performance similar to the WilTel plan's liability by seeking to match the interest rate sensitivity and credit sensitivity. The LDI Portfolio is managed to mitigate volatility in funded status deriving from changes in the discounted value of benefit obligations from market movements in the interest rate and credit components of the underlying discount curve.

To develop the assumption for the expected long-term rate of return on plan assets, we considered the following underlying assumptions: 2.25% current expected inflation, 1.0% to 1.5% real rate of return for long duration risk free investments and an additional 1.0% to 1.5% return premium for corporate credit risk. For U.S. and international equity, we assume an equity risk premium over cash equals to 4.0%. We then weighted these assumptions based on invested assets and assumed that investment expenses were offset by expected returns in excess of benchmarks, which resulted in the selection of the 7.0% expected long-term rate of return assumption for 2017.

Jefferies Plan Assets.  At December 31, 2017 and 2016, the Jefferies plan assets at fair value consisted of the following (in thousands):

(1) There are no plan assets classified within Level 3 of the fair value hierarchy.

(2) Listed equity securities are diversified across a spectrum of primarily U.S. large-cap companies.

Investment Policies and Strategies - Assets in the plan are invested under guidelines adopted by Jefferies Administrative Committee of the U.S. Pension Plan. Because the U.S. Pension Plan exists to provide a vehicle for funding future benefit obligations, the investment objectives of the portfolio take into account the nature and timing of future plan liabilities. The policy recognizes that the portfolio’s long-term investment performance and its ability to meet the plan’s overall objectives are dependent on the strategic asset allocation, which includes adequate diversification among assets classes.

In May 2017, Jefferies entered into an agreement with an external investment manager to invest and manage the plan’s assets under a strategy using a combination of two portfolios. The investment manager allocates the plan’s assets between a growth portfolio and a liability-driven portfolio according to certain target allocations and tolerance bands that are agreed to by Jefferies Administrative Committee of the U.S. Pension Plan. Such target allocations will take into consideration the plan’s funded ratio. The manager will also monitor the strategy and, as the plan’s funded ratio changes over time, will rebalance the strategy, if necessary, to be within the agreed tolerance bands and target allocations. The portfolios are comprised of certain common collective investment trusts that are established and maintained by the investment manager.

German Pension Plan

In connection with the acquisition of Jefferies Bache from Prudential in 2011, Jefferies acquired a defined benefit pension plan located in Germany for the benefit of eligible employees of Jefferies Bache in that territory. The German pension plan has no plan assets and is therefore unfunded; however, Jefferies has purchased insurance contracts from multi-national insurers held in the name of Jefferies Bache Limited to provide for the plan’s future obligations. The investment in these insurance contracts is included in Financial instruments owned - Trading assets in the Consolidated Statements of Financial Condition and has a fair value of $16.0 million and $15.2 million at December 31, 2017 and 2016, respectively. All costs relating to the plan (including insurance premiums and other costs as computed by the insurers) are paid by Jefferies. In connection with the acquisition, Prudential agreed that any insurance premiums and funding obligations related to pre-acquisition date service will be reimbursed to Jefferies by Prudential.

On December 28, 2017, a Liquidation Insurance Contract was entered into between Jefferies Bache Limited and Generali Lebensversicherung AG ("Generali") to transfer the defined benefit pension obligations and insurance contracts to Generali, for approximately €6.5 million, which was paid in January 2018 and which will release Jefferies from any and all obligations under the German Pension Plan. Subject to certain precedent conditions being fulfilled, this transaction is expected to be completed in the first quarter of 2018. In addition, on December 28, 2017, Jefferies entered into an agreement with Prudential under which it received $3.25 million as consideration for the release of Prudential by Jefferies from their indemnity relating to the German Pension Plan defined benefit pension obligations.

The provisions and assumptions used in the German pension plan are based on local conditions in Germany. Jefferies did not contribute to the plan during the year ended December 31, 2017.

The following tables summarize the changes in the projected benefit obligation and the components of net periodic pension cost for the years ended December 31, 2017, 2016 and 2015 (in thousands):

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Act. The Tax Act makes broad and complex changes to the U.S. tax code that will impact many areas of taxation, including, but not limited to, (1) reduction of the U.S. federal corporate tax rate from 35% to 21%; (2) elimination of the corporate alternative minimum tax; (3) the introduction of the base erosion anti-abuse tax, a new minimum tax; (4) a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries; (5) a new provision designed to tax global intangible low-taxed income; (6) a new limitation on deductible interest expense; (7) the repeal of the domestic production activity deduction; (8) limitations on the deductibility of certain executive compensation; (9) limitations on the use of foreign tax credits to reduce U.S. income tax liability; (10) limitations on NOLs generated after December 31, 2017, to 80% of taxable income; (11) requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over 8 years; and (12) bonus depreciation that will allow for full expensing of qualified property.

On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740, Income Taxes. SAB 118 provides a three-step process to be applied at each reporting period to account for and qualitatively disclose: (1) the effects of the change in tax law for which accounting is complete; (2) provisional amounts (or adjustments to provisional amounts) for the effects of the tax law where accounting is not complete, but that a reasonable estimate has been determined: and (3) where a reasonable estimate cannot yet be made and therefore taxes are reflected in accordance with the law prior to the enactment of the Tax Act.

Due to the complex nature of the Tax Act, we have not completed our accounting for the income tax effects of certain elements of the Tax Act. If we were able to make reasonable estimates of the effects of certain elements for which our analysis is not yet complete, we recorded a provisional estimate in the financial statements. If we were not yet able to make reasonable estimates of the impact of certain elements, we have not recorded any adjustments related to those elements and have continued accounting for them in accordance with ASC 740 on the basis of the tax laws in effect before the Tax Act. The ultimate impact of the Tax Act may differ from this estimate, possibly materially, due to changes in interpretations and assumptions, and guidance that may be issued and actions we may take in response to the Tax Act. We note that the Tax Act is complex and we continue to assess the impact that various provisions will have on our business.

Since the Tax Act was passed late in the fourth quarter of 2017, and ongoing guidance and accounting interpretation are expected over the next 12 months, we consider the accounting for the deferred tax asset remeasurements, the transition tax, and other items to be incomplete due to the forthcoming guidance and our ongoing analysis of final year-end data and tax positions. In connection with our initial analysis, we have recorded a discrete tax expense of $450.5 million as a provisional estimate of the impact of the Tax Act, including the portion related to Jefferies, during 2017 increasing our effective tax rate by 44.4% to 75.1%. This provisional estimate primarily consists of a $415.0 million expense related to the revaluation of our deferred tax asset and a $35.5 million expense related to the deemed repatriation of foreign earnings. Additionally, for the year ended December 31, 2017, our provision for income taxes was reduced by a $31.9 million benefit resulting from the repatriation of Jefferies earnings from certain of its foreign subsidiaries, along with their associated foreign tax credits.

For the year ended December 31, 2016, our provision for income taxes included a $24.9 million charge related to previously issued stock awards. The majority of the awards expired during the first quarter of 2016. The tax deductions associated with the remainder of the awards was less than the compensation cost recognized for financial reporting purposes. For the year ended December 31, 2015, we recorded a benefit related to certain state and local net operating loss carryforwards which we believe are more likely than not to be realized in the future, a significant portion of which resulted from enacted state and local tax law changes.

The following table presents the U.S. and non-U.S. components of income from continuing operations before income taxes for each of the three years in the period ended December 31, 2017 (in thousands):

	2017		2016			2015

(1) For purposes of this table, non-U.S. income is defined as income generated from operations located outside the U.S.

For each of the three years in the period ended December 31, 2017, income tax expense differed from the amounts computed by applying the U.S. Federal statutory income tax rate of 35% to income from continuing operations before income taxes as a result of the following (dollars in thousands):

	2017					2016					2015

The following table presents a reconciliation of gross unrecognized tax benefits for each of the three years in the period ended December 31, 2017 (in thousands):

	2017			2016			2015
Balance at beginning of period	$	148,848		$	150,867		$	148,590

Balance at end of period	$	169,020		$	148,848		$	150,867

Net interest expense related to unrecognized tax benefits was $9.7 million, $8.6 million and $4.2 millionfor the years ended December 31, 2017, 2016 and 2015, respectively. At December 31, 2017 and 2016, we had interest accrued of approximately $57.4 million and $47.7 million, respectively, included in Payables, expense accruals and other liabilities in the Consolidated Statements of Financial Condition. No material penalties were accrued for the years ended December 31, 2017 and 2016.

The statute of limitations with respect to our federal income tax returns has expired for all years through 2012. Our 2013 federal tax return is currently under examination by the Internal Revenue Service. Our New York State and New York City income tax returns are currently being audited for the 2012 to 2014 period and 2011 to 2012 period, respectively. Prior to becoming a wholly-owned subsidiary, Jefferies filed a consolidated U.S. federal income tax return with its qualifying subsidiaries and was subject to income tax in various states, municipalities and foreign jurisdictions. Jefferies is currently under examination by the Internal Revenue Service and other major tax jurisdictions. The statute of limitations with respect to Jefferies federal income tax returns has expired for all years through 2012.

We do not expect that resolution of these examinations will have a significant effect on our consolidated financial position, but could have a significant impact on the consolidated results of operations for the period in which resolution occurs. Over the next twelve months, we believe it is reasonably possible that various tax examinations will be concluded and statutes of limitation will expire which would have the effect of reducing the balance of unrecognized tax benefits by $14.0 million. If recognized, the total amount of unrecognized tax benefits reflected in the table above would lower our effective income tax rate.

The principal components of deferred taxes at December 31, 2017 and 2016 are as follows (in thousands):

	2017			2016
Deferred tax asset:
Net operating loss carryover	$	599,839		$	1,262,584

Net deferred tax asset	$	743,811		$	1,461,815

As of December 31, 2017, we have consolidated U.S. federal NOLs of $1.2 billion that may be used to offset the taxable income of any member of our consolidated tax group. In addition, we have $1.2 billion of U.S. federal NOLs that are only available to offset the taxable income of certain subsidiaries. Federal NOLs begin to expire in 2023, with a substantial amount expiring between 2023 and 2025. We have various state NOLs that expire at different times, which are reflected in the above table to the extent our estimate of future taxable income will be apportioned to those states. We have gross foreign net operating loss carryforwards of approximately $68.6 million. There is a valuation allowance with respect to $10.0 million of these foreign net operating loss carryforwards. Uncertainties that may affect the utilization of our tax attributes include future operating results, tax law changes, rulings by taxing authorities regarding whether certain transactions are taxable or deductible and expiration of carryforward periods.

Under certain circumstances, the ability to use the NOLs and future deductions could be substantially reduced if certain changes in ownership were to occur. In order to reduce this possibility, our certificate of incorporation includes a charter restriction that prohibits transfers of our common stock under certain circumstances.

We are currently evaluating the impact of the Tax Act on our indefinite reinvestment assertion. At December 31, 2016, we had approximately $157.0 million of earnings attributable to foreign subsidiaries that were indefinitely reinvested abroad and for which no U.S. federal income tax provision had been recorded. Accordingly, deferred tax liabilities of approximately $55.0 million had not been recorded with respect to these earnings at December 31, 2016.

(1) Represents dividends declared during the period on participating securities plus an allocation of undistributed earnings to participating securities. Net losses are not allocated to participating securities. Participating securities represent restricted stock and RSUs for which requisite service has not yet been rendered and amounted to weighted-average shares of 1,401,000, 1,986,800 and 6,500,000for the years ended December 31, 2017, 2016 and 2015, respectively. Dividends declared on participating securities during the years ended December 31, 2017, 2016 and 2015 were $0.4 million, $0.4 million and $1.5 million, respectively. Undistributed earnings are allocated to participating securities based upon their right to share in earnings if all earnings for the period had been distributed.

Options to purchase 656,894 and 1,000,137 weighted-average shares of common stock were outstanding during the years ended December 31, 2016 and 2015, respectively, but were not included in the computation of diluted per share amounts as the effect was antidilutive. Amounts for 2017 were not material.

(2) At December 31, 2017, $3,207.4 million within forward starting securities purchased under agreements to resell and $2,982.8 million within securities sold under agreements to repurchase settled within three business days.

Equity Commitments.  Equity commitments include commitments to invest in Jefferies joint venture, Jefferies Finance, and commitments to invest in private equity funds and in Jefferies Capital Partners, LLC, the manager of the private equity funds, which are managed by a team led by Brian P. Friedman, our President and a Director. As of December 31, 2017, Jefferies outstanding commitments relating to Jefferies Capital Partners, LLC and its private equity funds was $22.0 million.

See Note 10 for additional information regarding Jefferies investment in Jefferies Finance.

Our equity commitments also include our commitment to invest in 54 Madison, a fund which targets real estate projects. We plan to invest a cumulative total of $202.5 million to this fund, of which we have already contributed $144.8 million. Capital commitments are contingent upon approval of the related investment by the investment committee, of which we have two of the four seats. Through December 31, 2017, approved unfunded commitments totaled $28.0 million.

Additionally, as of December 31, 2017, we have other equity commitments to invest up to $14.4 million in various other investments.

Loan Commitments. From time to time Jefferies makes commitments to extend credit to investment banking and other clients in loan syndication, acquisition finance and securities transactions and to SPE sponsors in connection with the funding of CLO and other asset-backed transactions. These commitments and any related drawdowns of these facilities typically have fixed maturity dates and are contingent on certain representations, warranties and contractual conditions applicable to the borrower. As of December 31, 2017, Jefferies has $68.3 million of outstanding loan commitments to clients.

Loan commitments outstanding as of December 31, 2017, also include Jefferies portion of the outstanding secured revolving credit facility provided to Jefferies Finance to support loan underwritings by Jefferies Finance. At December 31, 2017, none of Jefferies $250.0 million commitment was funded.

In August 2014, we and Solomon Kumin established Folger Hill; we committed to provide Folger Hill with a three-year, $20.0 million revolving credit facility to fund its start-up and initial operating expenses. During the third quarter of 2017, the facility was amended to extend the maturity date until December 31, 2018 and to provide for an optional termination right for the Company with ten days prior written notice. As of December 31, 2017, $10.2 million has been provided to Folger Hill under the revolving credit facility.

Mortgage-Related and Other Purchase Commitments.  Jefferies enters into forward contracts to purchase mortgage participation certificates, mortgage-backed securities and consumer loans. The mortgage participation certificates evidence interests in mortgage loans insured by the Federal Housing Administration and the mortgage-backed securities are insured or guaranteed by Fannie Mae, Freddie Mac or Ginnie Mae. Jefferies frequently securitizes the mortgage participation certificates and mortgage-backed securities. The fair value of mortgage-related and other purchase commitments recorded in the Consolidated Statement of Financial Condition at December 31, 2017 was $37.6 million.

Underwriting Commitments. In connection with investment banking activities, Jefferies may from time to time provide underwriting commitments to its clients in connection with capital raising transactions.

Forward Starting Reverse Repos and Repos.  Jefferies enters into commitments to take possession of securities with agreements to resell on a forward starting basis and to sell securities with agreements to repurchase on a forward starting basis that are primarily secured by U.S. government and agency securities.

Other Unfunded Commitments.  Other unfunded commitments include obligations in the form of revolving notes to provide financing to asset-backed and CLO vehicles. Upon advancing funds, drawn amounts are collateralized by the assets of an entity.

Contingencies

We and our subsidiaries are parties to legal and regulatory proceedings that are considered to be either ordinary, routine litigation incidental to their business or not significant to our consolidated financial position. We and our subsidiaries are also involved, from time to time, in other exams, investigations and similar reviews (both formal and informal) by governmental and self-regulatory agencies regarding our businesses, certain of which may result in judgments, settlements, fines, penalties or other injunctions. We do not believe that any of these actions will have a significant adverse effect on our consolidated financial position or liquidity, but any amounts paid could be significant to results of operations for the period.

Guarantees

Derivative Contracts.  Jefferies dealer activities cause it to make markets and trade in a variety of derivative instruments. Certain derivative contracts that Jefferies has entered into meet the accounting definition of a guarantee under GAAP, including credit default swaps, written foreign currency options and written equity put options. On certain of these contracts, such as written interest rate caps and foreign currency options, the maximum payout cannot be quantified since the increase in interest or foreign exchange rates are not contractually limited by the terms of the contract. As such, we have disclosed notional values as a measure of Jefferies maximum potential payout under these contracts.

The following table summarizes the notional amounts associated with our derivative contracts meeting the definition of a guarantee under GAAP as of December 31, 2017 (in millions):

	Expected Maturity Date
Guarantee Type	2018		2019		2020 and 2021		2022 and 2023		2024 and Later		Notional/ Maximum Payout
Derivative contracts – non-credit related	$	24,454.8	$	2,420.2	$	150.5	$	45.9	$	466.3	$	27,537.7
Written derivative contracts – credit related	—		42.0		20.5		155.7		—		218.2
Total derivative contracts	$	24,454.8	$	2,462.2	$	171.0	$	201.6	$	466.3	$	27,755.9

The derivative contracts deemed to meet the definition of a guarantee under GAAP are before consideration of hedging transactions and only reflect a partial or "one-sided" component of any risk exposure. Written equity options and written credit default swaps are often executed in a strategy that is in tandem with long cash instruments (e.g., equity and debt securities). Jefferies substantially mitigates its exposure to market risk on these contracts through hedges, such as other derivative contracts and/or cash instruments and Jefferies manages the risk associated with these contracts in the context of its overall risk management framework. Jefferies believes notional amounts overstate its expected payout and that fair value of these contracts is a more relevant measure of its obligations. The fair value of derivative contracts meeting the definition of a guarantee is approximately $243.6 million as of December 31, 2017.

Berkadia.  We have agreed to reimburse Berkshire Hathaway for up to one-half of any losses incurred under a $1.5 billion surety policy securing outstanding commercial paper issued by an affiliate of Berkadia. As of December 31, 2017, the aggregate amount of commercial paper outstanding was $1.47 billion.

Other Guarantees.  Jefferies is a member of various exchanges and clearing houses. In the normal course of business Jefferies provides guarantees to securities clearinghouses and exchanges. These guarantees generally are required under the standard membership agreements, such that members are required to guarantee the performance of other members. Additionally, if a member becomes unable to satisfy its obligations to the clearinghouse, other members would be required to meet these shortfalls. To mitigate these performance risks, the exchanges and clearinghouses often require members to post collateral. Jefferies obligations under such guarantees could exceed the collateral amounts posted. Jefferies maximum potential liability under these arrangements cannot be quantified; however, the potential for Jefferies to be required to make payments under such guarantees is deemed remote.  Accordingly, no liability has been recognized for these arrangements.

Indemnification.  In connection with the 2013 sale of Empire Insurance Company, we agreed to indemnify the buyer for certain of Empire’s lease obligations that were assumed by another subsidiary of ours as part of the sale of Empire. Our subsidiary was subsequently sold in 2014 to HomeFed as part of the real estate transaction with HomeFed. Although HomeFed has agreed to indemnify us for these lease obligations, our indemnification obligation under the Empire transaction remains. The primary lease expires in 2018 and the aggregate amount of lease obligation as of December 31, 2017 was approximately $9.8 million. Substantially all of the space under the primary lease has been sublet to various third-party tenants for the full length of the lease term in amounts in excess of the obligations under the primary lease.

Standby Letters of Credit.  At December 31, 2017, Jefferies provided guarantees to certain counterparties in the form of standby letters of credit in the amount of $51.8 million. Standby letters of credit commit Jefferies to make payment to the beneficiary if the guaranteed party fails to fulfill its obligation under a contractual arrangement with that beneficiary. Since commitments associated with these collateral instruments may expire unused, the amount shown does not necessarily reflect the actual future cash funding requirement. Other subsidiaries of ours have outstanding letters of credit aggregating $15.0 million at December 31, 2017. Primarily all letters of credit expire within one year.

Net Capital Requirements

Net Capital Requirements

Jefferies operates as a broker-dealer registered with the SEC and member firms of the Financial Industry Regulatory Authority ("FINRA"). Jefferies LLC is subject to the Securities and Exchange Commission Uniform Net Capital Rule ("Rule 15c3-1"), which requires the maintenance of minimum net capital and has elected to calculate minimum capital requirements using the alternative method permitted by Rule 15c3-1 in calculating net capital. Jefferies LLC, as a dully-registered U.S. broker-dealer and futures commission merchant ("FCM"), is also subject to Rule 1.17 of the CFTC which sets forth minimum financial requirements. The minimum net capital requirement in determining excess net capital for a dually-registered U.S. broker-dealer and FCM is equal to the greater of the requirement under Rule 15c3-1 or CFTC Rule 1.17. In November 2017, Jefferies Execution Services, Inc. merged with and into Jefferies LLC, with Jefferies LLC as the surviving entity.

Jefferies LLC’s net capital and excess net capital as of December 31, 2017 were $1,418.9 million and $1,330.2 million, respectively.

FINRA is the designated examining authority for Jefferies U.S. broker-dealer and the NFA is the designated self-regulatory organization for Jefferies LLC as an FCM.

Certain other U.S. and non-U.S. subsidiaries of Jefferies are subject to capital adequacy requirements as prescribed by the regulatory authorities in their respective jurisdictions, including Jefferies International Limited which is authorized and regulated by the Financial Conduct Authority in the United Kingdom.

The regulatory capital requirements referred to above may restrict our ability to withdraw capital from Jefferies regulated subsidiaries. Some of our other consolidated subsidiaries also have credit agreements which may restrict the payment of cash dividends, or the ability to make loans or advances to the parent company.

(1) The first quarter of 2017 includes a pre-tax gain of $179.9 million related to the sale of Conwed Plastics, revenue of $175.2 million related to the increase in fair value of our investment in HRG and a pre-tax charge of $130.2 million related to an impairment of our equity investment in FXCM.

Net revenues for the first quarter of 2016 were impacted by a volatile and turbulent period in the capital markets, which primarily impacted Jefferies and our other market sensitive businesses. Net revenues in the first quarter of 2016 include losses of $82.2 million from Jefferies investment in two equity block positions, including KCG, and a loss of $53.2 million from a decline in fair value of our FXCM investment. The first quarter of 2016 also includes revenue of $65.6 million related to the increase in a corporate trading asset held at fair value.

(2) The second quarter of 2017 includes losses of $75.0 million from a decrease in fair value of our investment in HRG and revenue of $95.8 million from an increase in fair value of Jefferies investment in KCG.

Net revenues in the second quarter of 2016 includes revenue of $55.8 million from an increase in fair value of Jefferies investment in KCG and a loss of $47.9 million from a decline in fair value of our FXCM investment.

(3) The third quarter of 2017 includes losses of $97.9 million from a decrease in fair value of our investment in HRG.

The third quarter of 2016 includes revenue of $91.8 million from an increase in fair value of our investment in HRG and revenue of $42.7 million from an increase in fair value of our FXCM investment. The third quarter of 2016 also includes a pre-tax charge of $55.0 million related to an impairment of JETX's unproved oil and gas properties in the East Eagle Ford and Houston County.

(4) As discussed further in Note 20, the fourth quarter of 2017 includes a discrete tax charge of $450.5 million as a provisional estimate of the impact of the Tax Act. This provisional estimate primarily consists of a $415.0 million expense related to the revaluation of our deferred tax assets and a $35.5 million expense related to the deemed repatriation of foreign earnings.

In 2017 and 2016, the totals of quarterly per share amounts may not equal annual per share amounts because of changes in outstanding shares during the year.

LEUCADIA NATIONAL CORPORATION

(PARENT COMPANY ONLY)

Notes to Condensed Financial Statements

1. Introduction and Basis of Presentation

The notes to the consolidated financial statements of Leucadia National Corporation and Subsidiaries (the "Company") are incorporated by reference into this schedule. For purposes of these condensed non-consolidated financial statements, the Company's wholly-owned and majority owned subsidiaries are accounted for using the equity method of accounting ("equity method subsidiaries").

The Parent Company Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (" GAAP"). The significant accounting policies of the Parent Company Financial Statements are those used by the Company on a consolidated basis, to the extent applicable. For further information regarding the significant accounting policies refer to Note 2, Significant Accounting Policies, in the Company's consolidated financial statements included in the 2017 10-K.

The Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these financial statements in conformity with GAAP. The most important of these estimates and assumptions relate to fair value measurements, goodwill and intangible assets, the ability to realize deferred tax assets and the recognition and measurement of uncertain tax positions. Although these and other estimates and assumptions are based on the best available information, actual results could be materially different from these estimates.

2. Cash Flows

Supplemental cash flow information related to the Parent Company for the years ended December 31, 2017, 2016 and 2015 is as follows (in thousands):

	2017		2016			2015
Cash paid during the year for:
Interest	$	57,813	$	57,813		$	95,074
Income tax payments (refunds), net	$	1,440	$	(10,199	)	$	(2,332	)
Non-cash investing activities:
Investments contributed to subsidiary	$	25,328	$	423,009		$	—
Investments transferred from subsidiary	$	—	$	2,022		$	—
Dividends received from subsidiaries	$	32,792	$	—		$	—

3. Transactions with Subsidiaries

The Parent Company has transactions with its equity method subsidiaries, many of which are structured as interest bearing advances to/from its subsidiaries. Intercompany interest expense primarily reflects the interest on funding advances incurred by the Parent to its wholly-owned subsidiary which holds assets related to its treasury function. Interest is incurred on funding advances based on the prime rate plus .125%. Although there is frequent cash movement between these subsidiaries and the Parent, they do not represent cash dividends. As such, the Parent Company received no cash dividends from its subsidiaries during the three years ended December 31, 2017.

Historically, excess cash was provided to the Parent Company by its subsidiaries in the form of loans rather than as distributions. Through a series of steps, the Parent Company is reducing these intercompany loans to zero. From January 1, 2018 through February 15, 2018, the Parent Company received non-cash dividends totaling $7.9 billion from its subsidiaries. Of this amount, $7.9 billion will be reflected as a decrease in our Investment in subsidiaries, $0.2 billion will be reflected as a decrease to Advances to subsidiaries and $8.1 billion will be reflected as a decrease to Advances from subsidiaries.

4. Commitments, Contingencies and Guarantees

In the normal course of its business, the Parent Company has various commitments, contingencies and guarantees as described in Note 24, Commitments, Contingencies and Guarantees, and Note 16, Mezzanine Equity, in the Company's consolidated financial statements.

5. Restricted Net Assets

For a discussion of the Company's regulatory requirements, see Note 25, Net Capital Requirements, in the Company's consolidated financial statements. Some of the Company's consolidated subsidiaries also have credit agreements which may restrict the payment of cash dividends, or the ability to make loans or advances to the Parent Company.

At December 31, 2017 and 2016, $6.1 billion and $6.0 billion, respectively, of net assets of the Parent Company's consolidated subsidiaries are restricted as to the payment of cash dividends, or the ability to make loans or advances to the Parent Company. At December 31, 2017 and 2016, $5.1 billion and $4.8 billion, respectively, of these net assets are restricted as they reflect regulatory capital requirements or require regulatory approval prior to the payment of cash dividends and advances to the Parent Company.

Included in retained earnings of the Parent Company at December 31, 2017 are $202.9 million of undistributed earnings of unconsolidated associated companies. For further information, see Note 10, Loans to and Investments in Associated Companies, in the Company's consolidated financial statements.

Significant Accounting Policies (Policy)

12 Months Ended

Dec. 31, 2017

Accounting Policies [Abstract]

Consolidation

Consolidation

Our policy is to consolidate all entities in which we can vote a majority of the outstanding voting stock. In addition, we consolidate entities which meet the definition of a variable interest entity for which we are the primary beneficiary. The primary beneficiary is the party who has the power to direct the activities of a variable interest entity that most significantly impact the entity’s economic performance and who has an obligation to absorb losses of the entity or a right to receive benefits from the entity that could potentially be significant to the entity. We consider special allocations of cash flows and preferences, if any, to determine amounts allocable to noncontrolling interests. All intercompany transactions and balances are eliminated in consolidation.

In situations where we have significant influence, but not control, of an entity that does not qualify as a variable interest entity, we apply either the equity method of accounting or fair value accounting pursuant to the fair value option election under GAAP.  We have also formed nonconsolidated investment vehicles with third-party investors that are typically organized as partnerships or limited liability companies. Our subsidiaries may act as general partner or managing member for these investment vehicles and have generally provided the third-party investors with termination or “kick-out” rights.

Revenue Recognition Policies

Revenue Recognition Policies

Beef Processing and Other Operations

Revenues are recognized when the following conditions are met: (1) collectibility is reasonably assured; (2) title to the product has passed or the service has been rendered and earned; (3) persuasive evidence of an arrangement exists; and (4) there is a fixed or determinable price. National Beef’s revenues are recognized based on the terms of the sale, which for beef processing operations is typically upon delivery to customers. Manufacturing revenues are recognized when title passes.

Investment Banking Activities

Commissions and Other Fees. All customer securities transactions are reported in the Consolidated Statements of Financial Condition on a settlement date basis with related income reported on a trade date basis. We permit institutional customers to allocate a portion of their gross commissions to pay for research products and other services provided by third parties. The amounts allocated for those purposes are commonly referred to as soft dollar arrangements. These arrangements are accounted for on an accrual basis and, as we are not the primary obligor for these arrangements, netted against commission revenues in the Consolidated Statements of Operations. In addition, we earn asset-based fees associated with the management and supervision of assets, account services and administration related to customer accounts.

Principal Transactions. Trading assets and trading liabilities (all of which are recorded on a trade-date basis) are carried at fair value with gains and losses reflected in Principal transaction revenues in the Consolidated Statements of Operations, except for derivatives accounted for as hedges (see Hedge Accounting section, herein and Note 5). Fees received on loans carried at fair value are also recorded within Principal transaction revenues.

Investment Banking.  Underwriting revenues and fees from mergers and acquisitions, restructuring and other investment banking advisory assignments or engagements are recorded when the services related to the underlying transactions are completed under the terms of the assignment or engagement. Expenses associated with such assignments are deferred until reimbursed by the client, the related revenue is recognized or the engagement is otherwise concluded. Expenses are recorded net of client reimbursements and netted against revenues. Unreimbursed expenses with no related revenues are included in Selling, general and administrative expenses in the Consolidated Statements of Operations.

Interest Revenue and Expense.  Interest expense that is deducted from Revenues to arrive at Net revenues is related to Jefferies operations. Contractual interest on Trading assets and Trading liabilities is recognized on an accrual basis as a component of Interest income and Interest expense. Interest flows on derivative trading transactions and dividends are included as part of the fair valuation of these contracts and recognized in Principal transactions in the Consolidated Statements of Operations rather than as a component of interest income or expense. Interest on short- and long-term borrowings is recorded on an accrual basis, except for those for which we have elected the fair value option, as Interest expense. Discounts/premiums arising on long-term debt are accreted/amortized to Interest expense using the effective yield method over the remaining lives of the underlying debt obligations. Interest revenue related to Securities borrowed and Securities purchased under agreements to resell activities and interest expense related to Securities loaned and Securities sold under agreements to repurchase activities are recognized on an accrual basis.

Hedge Accounting

Hedge Accounting

Jefferies applies hedge accounting using interest rate swaps designated as fair value hedges of changes in the benchmark interest rate of fixed rate senior long-term debt. Jefferies interest rate swaps are included as derivative contracts in Trading assets and Trading liabilities in the Consolidated Statements of Financial Condition. Jefferies uses regression analysis to perform ongoing prospective and retrospective assessments of the effectiveness of these hedging relationships. A hedging relationship is deemed effective if the change in fair value of the interest rate swap and the change in the fair value of the long-term debt due to changes in the benchmark interest rate offset within a range of 80% to 125%. The impact of valuation adjustments related to Jefferies own credit spreads and counterparty credit spreads are included in the assessment of effectiveness.

For qualifying fair value hedges of benchmark interest rates, the change in the fair value of the derivative and the change in fair value of the long-term debt provide offset of one another, and together with any resulting ineffectiveness, are recorded in Interest expense. See Note 5 for further information.

Cash Equivalents

Cash Equivalents

Cash equivalents include highly liquid investments, including money market funds and certificates of deposit, not held for resale with original maturities of three months or less.

Cash and Securities Segregated and on Deposit for Regulatory Purposes or Deposited With Clearing and Depository Organizations

Cash and Securities Segregated and on Deposit for Regulatory Purposes or Deposited With Clearing and Depository Organizations

In accordance with Rule 15c3-3 of the Securities Exchange Act of 1934, Jefferies LLC, as a broker-dealer carrying client accounts, is subject to requirements related to maintaining cash or qualified securities in a segregated reserve account for the exclusive benefit of its clients. Certain other entities are also obligated by rules mandated by their primary regulators to segregate or set aside cash or equivalent securities to satisfy regulations, promulgated to protect customer assets. In addition, certain exchange and/or clearing organizations require cash and/or securities to be deposited by us to conduct day to day activities.

Financial Instruments and Fair Value

Financial Instruments and Fair Value

Trading assets and Trading liabilities are recorded at fair value, either as required by accounting pronouncements or through the fair value option election. Gains and losses on trading assets and trading liabilities are recognized in our Consolidated Statements of Operations in Principal transactions. Available for sale securities are reflected at fair value, with unrealized gains and losses reflected as a separate component of equity, net of taxes. When sold, realized gains and losses on available for sale securities are reflected in the caption Net realized securities gains. The cost of securities sold is based on average cost. Fair value is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price).

Fair Value Hierarchy

Fair Value Hierarchy

In determining fair value, we maximize the use of observable inputs and minimize the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from independent sources. Unobservable inputs reflect our assumptions that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. We apply a hierarchy to categorize our fair value measurements broken down into three levels based on the transparency of inputs as follows:

Level 1: Quoted prices are available in active markets for identical assets or liabilities as of the reported date. Valuation adjustments and block discounts are not applied to Level 1 instruments.

Level 2: Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these financial instruments includes cash instruments for which quoted prices are available but traded less frequently, derivative instruments fair values for which have been derived using model inputs that are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed.

Level 3: Instruments that have little to no pricing observability as of the reported date. These financial instruments are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation.

Financial instruments are valued at quoted market prices, if available. Certain financial instruments have bid and ask prices that can be observed in the marketplace. For financial instruments whose inputs are based on bid-ask prices, the financial instrument is valued at the point within the bid-ask range that meets our best estimate of fair value. We use prices and inputs that are current as of the measurement date. For financial instruments that do not have readily determinable fair values using quoted market prices, the determination of fair value is based upon consideration of available information, including types of financial instruments, current financial information, restrictions on dispositions, fair values of underlying financial instruments and quotations for similar instruments.

The valuation of financial instruments may include the use of valuation models and other techniques. Adjustments to valuations derived from valuation models may be made when, in management’s judgment, features of the financial instrument such as its complexity, the market in which the financial instrument is traded and risk uncertainties about market conditions require that an adjustment be made to the value derived from the models. Adjustments from the price derived from a valuation model reflect management’s judgment that other participants in the market for the financial instrument being measured at fair value would also consider in valuing that same financial instrument. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment.

The availability of observable inputs can vary and is affected by a wide variety of factors, including, for example, the type of financial instrument and market conditions. As the observability of prices and inputs may change for a financial instrument from period to period, this condition may cause a transfer of an instrument among the fair value hierarchy levels. Transfers among the levels are recognized at the beginning of each period. The degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.

Valuation Process for Financial Instruments

Valuation Process for Financial Instruments

The Jefferies Independent Price Verification ("IPV") Group, which is part of the Jefferies finance department, in partnership with Jefferies Risk Management, is responsible for establishing Jefferies valuation policies and procedures. The IPV Group and Risk Management, which are independent of business functions, play an important role and serve as a control function in determining that Jefferies financial instruments are appropriately reflected at fair value. This is particularly important where prices or valuations that require inputs are less observable. In the event that observable inputs are not available, the control processes are designed to assure that the valuation approach utilized is appropriate and consistently applied and that the assumptions are reasonable. The IPV Group reports to the Jefferies Global Controller and is subject to the oversight of the IPV Committee, which includes senior members of Jefferies finance department and other personnel. Jefferies independent price verification policies and procedures are reviewed, at a minimum, annually and changes to the policies require the approval of the IPV Committee.

Price Testing Process.  Jefferies business units are responsible for determining the fair value of Jefferies financial instruments using approved valuation models and methodologies. In order to ensure that the business unit valuations represent a fair value exit price, the IPV Group tests and validates the fair value of the financial instruments inventory. In the testing process, the IPV Group obtains prices and valuation inputs from sources independent of Jefferies, consistently adheres to established procedures set forth in the valuation policies for sourcing prices and valuation inputs and utilizing valuation methodologies. Sources used to validate fair value prices and inputs include, but are not limited to, exchange data, recently executed transactions, pricing data obtained from third party vendors, pricing and valuation services, broker quotes and observed comparable transactions.

To the extent discrepancies between the business unit valuations and the pricing or valuations resulting from the price testing process are identified, such discrepancies are investigated by the IPV Group and fair values are adjusted, as appropriate. The IPV Group maintains documentation of its testing, results, rationale and recommendations and prepares a monthly summary of its valuation results. This process also forms the basis for the classification of fair values within the fair value hierarchy (i.e., Level 1, Level 2 or Level 3). The IPV Group utilizes the additional expertise of Risk Management personnel in valuing more complex financial instruments and financial instruments with less or limited pricing observability. The results of the valuation testing are reported to the IPV Committee on a monthly basis, which discusses the results and determines the financial instrument fair values in the consolidated financial statements. At each quarter end, the overall valuation results, as determined by the IPV Committee, are presented to the Jefferies Audit Committee.

Judgment exercised in determining Level 3 fair value measurements is supplemented by daily analysis of profit and loss performed by the Product Control functions. Gains and losses, which result from changes in fair value, are evaluated and corroborated daily based on an understanding of each trading desk's overall risk positions and developments in a particular market on the given day.  Valuation techniques generally rely on recent transactions of suitably comparable financial instruments and use the observable inputs from those comparable transactions as a validation basis for Level 3 inputs. Level 3 fair value measurements are further validated through subsequent sales testing and market comparable sales, if such information is available. Level 3 fair value measurements require documentation of the valuation rationale applied, which is reviewed for consistency in application from period to period.

Third Party Pricing Information.  Pricing information obtained from external data providers (including independent pricing services and brokers) may incorporate a range of market quotes from dealers, recent market transactions and benchmarking model derived prices to quoted market prices and trade data for comparable securities. External pricing data is subject to evaluation for reasonableness by the IPV Group using a variety of means including comparisons of prices to those of similar product types, quality and maturities, consideration of the narrowness or wideness of the range of prices obtained, knowledge of recent market transactions and an assessment of the similarity in prices to comparable dealer offerings in a recent time period. Jefferies processes challenges the appropriateness of pricing information obtained from external data providers (including independent pricing services and brokers) to validate the data for consistency with the definition of a fair value exit price. Jefferies process includes understanding and evaluating the external data providers’ valuation methodologies. For corporate, U.S. government and agency, municipal debt securities, and loans, to the extent independent pricing services or broker quotes are utilized in Jefferies valuation process, the vendor service providers are collecting and aggregating observable market information as to recent trade activity and active bid-ask submissions. The composite pricing information received from the independent pricing service is thus not based on unobservable inputs or proprietary models. For mortgage- and other asset-backed securities, collateralized debt obligations ("CDOs") and collateralized loan obligations ("CLOs"), the independent pricing services use a matrix evaluation approach incorporating both observable yield curves and market yields on comparable securities as well as implied inputs from observed trades for comparable securities in order to determine prepayment speeds, cumulative default rates and loss severity. Further, Jefferies considers pricing data from multiple service providers as available as well as compares pricing data to prices observed for recent transactions, if any, in order to corroborate valuation inputs.

Model Review Process.  If a pricing model is used to determine fair value, the pricing model is reviewed for theoretical soundness and appropriateness by Risk Management, independent from the trading desks, and then approved by Risk Management to be used in the valuation process. Review and approval of a model for use may include benchmarking the model against relevant third party valuations, testing sample trades in the model, backtesting the results of the model against actual trades and stress-testing the sensitivity of the pricing model using varying inputs and assumptions.  In addition, recently executed comparable transactions and other observable market data are considered for purposes of validating assumptions underlying the model. Models are independently reviewed and validated by Risk Management annually or more frequently if market conditions or use of the valuation model changes.

Investments in Managed Funds

Investments in Managed Funds

Investments in managed funds include our investments in funds managed by us and our investments in related party managed funds. Investments in nonconsolidated managed funds are accounted for at fair value based on the net asset value (“NAV”) of the funds provided by the fund managers with gains or losses included in the Consolidated Statements of Operations.

Asset management fees and investment income from managed funds include revenues we earn from management, administrative and performance fees from funds and accounts managed by us, revenues from management and performance fees we earn from related-party managed funds and investment income from our investments in these funds. We earn fees in connection with management and investment advisory services performed for various funds and managed accounts. These fees are based on assets under management or an agreed upon notional amount and may include performance fees based upon the performance of the funds. Management and administrative fees are generally recognized over the period that the related service is provided. Generally, performance fees are earned when the return on assets under management exceeds certain benchmark returns, “high-water marks” or other performance targets. Performance fees are accrued (or reversed) on a monthly basis based on measuring performance to date versus any relevant benchmark return hurdles stated in the investment management agreement. Performance fees are not subject to adjustment once the measurement period ends (generally annual periods) and the performance fees have been realized.

Loans to and Investments in Associated Companies

Loans to and Investments in Associated Companies

Loans to and investments in associated companies include investments in private equity and other operating entities in which we exercise significant influence over operating and capital decisions and loans issued in connection with such investments. Loans to and investments in associated companies are accounted for using the equity method. See Note 10 for additional information regarding certain of these investments.

Under the equity method of accounting, our share of the investee’s underlying net income or loss is recorded as Income (loss) related to associated companies, or as part of Other revenues if such investees are considered to be an extension of our business.  Income (loss) for investees for which the fair value option was elected is reported as Principal transactions revenues.

Receivables

Receivables

At December 31, 2017 and 2016, Receivables include receivables from brokers, dealers and clearing organizations of $2,635.2 million and $2,062.9 million, respectively, and receivables from customers of securities operations of $1,563.8 million and $843.1 million, respectively.

Securities Borrowed And Securities Loaned

Securities Borrowed and Securities Loaned

Securities borrowed and securities loaned are carried at the amounts of cash collateral advanced and received in connection with the transactions and accounted for as collateralized financing transactions. In connection with both trading and brokerage activities, Jefferies borrows securities to cover short sales and to complete transactions in which customers have failed to deliver securities by the required settlement date, and lend securities to other brokers and dealers for similar purposes. Jefferies has an active securities borrowed and lending matched book business in which it borrows securities from one party and lends them to another party. When Jefferies borrows securities, it generally provides cash to the lender as collateral, which is reflected in the Consolidated Statements of Financial Condition as Securities borrowed. Jefferies earns interest revenues on this cash collateral. Similarly, when Jefferies lends securities to another party, that party provides cash to Jefferies as collateral, which is reflected in the Consolidated Statements of Financial Condition as Securities loaned. Jefferies pays interest expense on the cash collateral received from the party borrowing the securities. The initial collateral advanced or received approximates or is greater than the fair value of the securities borrowed or loaned. Jefferies monitors the fair value of the securities borrowed and loaned on a daily basis and requests additional collateral or returns excess collateral, as appropriate.

Securities Purchased Under Agreements to Resell and Securities Sold Under Agreements to Repurchase

Securities Purchased Under Agreements to Resell and Securities Sold Under Agreements to Repurchase

Securities purchased under agreements to resell and Securities sold under agreements to repurchase (collectively "repos") are accounted for as collateralized financing transactions and are recorded at their contracted resale or repurchase amount plus accrued interest. Jefferies earns and incurs interest over the term of the repo, which is reflected in Interest revenue and Interest expense in the Consolidated Statements of Operations on an accrual basis. Repos are presented in the Consolidated Statements of Financial Condition on a net-basis-by counterparty, where permitted by GAAP. The fair value of the underlying securities is monitored daily versus the related receivable or payable balances. Should the fair value of the underlying securities decline or increase, additional collateral is requested or excess collateral is returned, as appropriate.

Property, Equipment and Leasehold Improvements

Property, Equipment and Leasehold Improvements

Property, equipment and leasehold improvements are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization are provided principally on the straight-line method over the estimated useful lives of the assets or, if less, the term of the underlying lease.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets

We evaluate our long-lived assets for impairment whenever events or changes in circumstances indicate, in management’s judgment, that the carrying value of such assets may not be recoverable. When testing for impairment, we group our long-lived assets with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities (or asset group). The determination of whether an asset group is recoverable is based on management’s estimate of undiscounted future cash flows directly attributable to the asset group as compared to its carrying value. If the carrying amount of the asset group is greater than the undiscounted cash flows, an impairment loss would be recognized for the amount by which the carrying amount of the asset group exceeds its estimated fair value.

In 2015, we recorded impairment charges in Selling, general and other expenses of $27.7 million, primarily related to a $20.3 million impairment at JETX and an impairment charge related to National Beef's Brawley plant of $4.7 million. For the oil and gas impairment test related to proved properties, we compare expected undiscounted future net cash flows to the unamortized capitalized cost of the asset. If the future undiscounted net cash flows are lower than the unamortized capital cost, we reduce the capitalized cost to fair market value. We used a third party reserve report in which the cash flows were calculated using West Texas Intermediate (oil) and Henry Hub (gas) NYMEX futures prices as of December 31, 2015. For one of our oil fields, the future undiscounted net cash flows were lower than the unamortized capital cost and as a result, we wrote off the total capital cost.

In 2016, JETX recorded impairment charges in Selling, general and other expenses of $56.3 million related to write-downs of unproved oil and gas properties. JETX assesses its unproved oil and gas properties for impairment based on remaining lease terms, drilling results or future plans to develop acreage and they record impairment expense for any decline in value. In the third quarter of 2016, JETX curtailed development of both its southern acreage in the East Eagle Ford and its Houston County acreage. As a result, an impairment was recorded for the difference between the carrying value and the estimated net realizable value of the acreage.

In 2017, JETX decided to focus on its other higher returning acreage and as a result wrote off the remaining carrying value for its Houston County acreage. JETX recorded an impairment charge of $10.1 million in Selling, general and other expenses in the third quarter of 2017 related to the write-down of unproved oil and gas properties.

Substantially all of our operating businesses sell products or services that are impacted by general economic conditions in the U.S. and to a lesser extent internationally. In recent years, general economic conditions reduced the demand for products or services sold by our operating subsidiaries and/or resulted in reduced pricing for products or services. A worsening of current economic conditions could cause a decline in estimated future cash flows expected to be generated by our operations and investments. If future undiscounted cash flows are estimated to be less than the carrying amounts of the asset groups used to generate those cash flows in subsequent reporting periods, particularly for those with large investments in intangible assets, property and equipment and other long-lived assets (for example, Jefferies, National Beef, manufacturing, oil and gas production and development and certain associated company investments), impairment charges would have to be recorded.

Intangible Assets, Net and Goodwill

Intangible Assets, Net and Goodwill

Intangible Assets.  Intangible assets deemed to have finite lives are generally amortized on a straight-line basis over their estimated useful lives, where the useful life is the period over which the asset is expected to contribute directly, or indirectly, to our future cash flows. Intangible assets are reviewed for impairment on an interim basis when certain events or circumstances exist. If future undiscounted cash flows are estimated to be less than the carrying amounts of the asset groups used to generate those cash flows in subsequent reporting periods, particularly for those with large investments in amortizable intangible assets, impairment charges would have to be recorded.

An intangible asset with an indefinite useful life is not amortized but assessed for impairment annually, or more frequently, when certain events or circumstances exist indicating an assessment for impairment is necessary. Impairment exists when the carrying amount exceeds its fair value. Fair value will be determined using valuation techniques consistent with what a market participant would use. All of our indefinite-lived intangible assets were recognized in connection with the Jefferies acquisition, and our annual impairment testing date for Jefferies is as of August 1.

Goodwill.  At acquisition, we allocate the cost of a business acquisition to the specific tangible and intangible assets acquired and liabilities assumed based upon their fair values. Significant judgments and estimates are often made by management to determine these values, and may include the use of appraisals, consideration of market quotes for similar transactions, use of discounted cash flow techniques or consideration of other information we believe to be relevant. Any excess of the cost of a business acquisition over the fair values of the net assets and liabilities acquired is recorded as goodwill, which is not amortized to expense. Substantially all of our goodwill was recognized in connection with the Jefferies acquisition.

At least annually, and more frequently if warranted, we will assess whether goodwill has been impaired. If the estimated fair value exceeds the carrying value, goodwill at the reporting unit level is not impaired. If the estimated fair value is less than carrying value, further analysis is necessary to determine the amount of impairment, if any, by comparing the implied fair value of the reporting unit’s goodwill to the carrying value of the reporting unit’s goodwill. The fair values will be based on widely accepted valuation techniques that we believe market participants would use, although the valuation process requires significant judgment and often involves the use of significant estimates and assumptions. The methodologies we utilize in estimating fair value include market capitalization, price-to-book multiples of comparable exchange traded companies, multiples of merger and acquisitions of similar businesses and/or projected cash flows. The estimates and assumptions used in determining fair value could have a significant effect on whether or not an impairment charge is recorded and the magnitude of such a charge. Adverse market or economic events could result in impairment charges in future periods. Our annual goodwill impairment testing date related to Jefferies is as of August 1 and National Beef as of December 31.

Inventories and Cost of Sales

Inventories and Cost of Sales

National Beef’s inventories consist primarily of beef products, beef by-products and supplies, and are stated at the lower of cost or net realizable value, with cost principally determined under the first-in-first-out method for beef products and average cost for supplies.

Manufacturing inventories are stated at the lower of cost or net realizable value, with cost principally determined under the first-in-first-out method. Manufacturing cost of sales principally includes product and manufacturing costs, inbound and outbound shipping costs and handling costs.

National Beef and manufacturing inventories are classified as Other assets in the Consolidated Statements of Financial Condition.

Payables, Expense Accruals and other Liabilities

Payables, expense accruals and other liabilities

At December 31, 2017 and 2016, Payables, expense accruals and other liabilities include payables to brokers, dealers and clearing organizations of $2,228.9 million and $3,290.4 million, respectively, and payables to customers of securities operations of $2,664.0 million and $2,297.3 million, respectively.

Income Taxes

Income Taxes

We record a valuation allowance to reduce our net deferred tax asset to the net amount that is more likely than not to be realized.  If in the future we determine that it is more likely than not that we will be able to realize our net deferred tax asset in excess of our net recorded amount, an adjustment to increase the net deferred tax asset would increase income in such period. If in the future we were to determine that we would not be able to realize all or part of our recorded net deferred tax asset, an adjustment to decrease the net deferred tax asset would be charged to income in such period. We are required to consider all available evidence, both positive and negative, and to weigh the evidence when determining whether a valuation allowance is required and the amount of such valuation allowance. Generally, greater weight is required to be placed on objectively verifiable evidence when making this assessment, in particular on recent historical operating results.

Our estimate of future taxable income considers all available evidence, both positive and negative, about our operating businesses and investments, includes an aggregation of individual projections for each significant operating business and investment, estimated apportionment factors for state and local taxing jurisdictions and includes all future years that we estimate we will have available net operating loss carryforwards (“NOLs”) (until 2035). We believe that our estimate of future taxable income is reasonable but inherently uncertain, and if our current or future operations and investments generate taxable income different than the projected amounts, further adjustments to the valuation allowance are possible. The current balance of the deferred tax valuation allowance principally reserves for NOLs of certain subsidiaries that are not available to offset income generated by other members of the consolidated tax return group.

We also record reserves for unrecognized tax benefits based on our assessment of the probability of successfully sustaining tax filing positions.  Interest and penalties, if any, are recorded as components of income tax expense. Management exercises significant judgment when assessing the probability of successfully sustaining tax filing positions, and in determining whether a contingent tax liability should be recorded and if so estimating the amount. If our tax filing positions are successfully challenged, payments could be required that are in excess of reserved amounts or we may be required to reduce the carrying amount of our net deferred tax asset, either of which could be significant to our Consolidated Statement of Financial Condition or results of operations.

Share-based Compensation

Share-based Compensation

Share-based awards are measured based on the fair value of the award as determined in accordance with GAAP and recognized over the required service or vesting period. Certain executive share-based awards contain market, performance and service conditions. Market conditions are incorporated into the grant-date fair value using a Monte Carlo valuation model. Compensation expense for awards with market conditions is recognized over the service period and is not reversed if the market condition is not met. Awards with performance conditions are amortized over the service period if it is determined that it is probable that the performance condition will be achieved. The fair value of options and warrants are estimated at the date of grant using the Black-Scholes option pricing model. Expected forfeitures are included in determining share-based compensation expense.

Foreign Currency Translation

Foreign Currency Translation

Assets and liabilities of foreign subsidiaries are translated to U.S. dollars using the currency exchange rates at the end of the relevant period. Revenues and expenses are translated at average exchange rates during the period. The effects of exchange rate changes on the translation of the balance sheets, net of hedging gains or losses and taxes, if any, are included in other comprehensive income (loss) in the Consolidated Statements of Comprehensive Income (Loss) and classified as Accumulated other comprehensive income in the Consolidated Statements of Financial Condition and Consolidated Statements of Changes in Equity. Gains or losses resulting from Jefferies foreign currency transactions are included in Principal transactions in the Consolidated Statements of Operations.

Earnings per Common Share

Earnings per Common Share

Basic earnings per share ("EPS") is computed by dividing net earnings available to common shareholders by the weighted average number of common shares outstanding and certain other shares committed to be, but not yet issued. Net earnings available to common shareholders represent net earnings to common shareholders reduced by the allocation of earnings to participating securities. Losses are not allocated to participating securities. Common shares outstanding and certain other shares committed to be, but not yet issued, include restricted stock and restricted stock units ("RSUs") for which no future service is required. Diluted EPS is computed by dividing net earnings available to common shareholders plus dividends on dilutive mandatorily redeemable convertible preferred shares and interest on convertible notes by the weighted average number of common shares outstanding and certain other shares committed to be, but not yet issued, plus all dilutive common stock equivalents outstanding during the period.

Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and, therefore, are included in the earnings allocation in computing earnings per share under the two-class method of earnings per share. Restricted stock and RSUs granted as part of share-based compensation contain nonforfeitable rights to dividends and dividend equivalents, respectively, and therefore, prior to the requisite service being rendered for the right to retain the award, restricted stock and RSUs meet the definition of a participating security. As such, we calculate basic and diluted earnings per share under the two-class method. RSUs granted under the senior executive compensation plan are not considered participating securities as the rights to dividend equivalents are forfeitable.

Securitization Activities

Securitization Activities

Jefferies engages in securitization activities related to corporate loans, consumer loans, commercial mortgage loans and mortgage-backed and other asset-backed securities. Such transfers of financial assets are accounted for as sales when Jefferies has relinquished control over the transferred assets. The gain or loss on sale of such financial assets depends, in part, on the previous carrying amount of the assets involved in the transfer allocated between the assets sold and the retained interests, if any, based upon their respective fair values at the date of sale. Jefferies may retain interests in the securitized financial assets as one or more tranches of the securitization. These retained interests are included within Trading assets in the Consolidated Statements of Financial Condition at fair value. Any changes in the fair value of such retained interests are recognized within Principal transactions in the Consolidated Statements of Operations.

When a transfer of assets does not meet the criteria of a sale, the transfer is accounted for as a secured borrowing and Jefferies continues to recognize the assets of a secured borrowing, and recognize the associated financing in Other secured financings in the Consolidated Statements of Financial Condition.

Beginning in 2014, another of our subsidiaries utilized a special purpose entity to securitize automobile loans receivable. This special purpose entity is a variable interest entity and our subsidiary is the primary beneficiary; the related assets and the secured borrowings are recognized in the Consolidated Statement of Financial Condition. These secured borrowings do not have recourse to our subsidiary’s general credit.

Contingencies

Contingencies

In the normal course of business, we have been named, from time to time, as a defendant in legal and regulatory proceedings. We are also involved, from time to time, in other exams, investigations and similar reviews (both formal and informal) by governmental and self-regulatory agencies regarding our businesses, certain of which may result in judgments, settlements, fines, penalties or other injunctions.

We recognize a liability for a contingency when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. If the reasonable estimate of a probable loss is a range, we accrue the most likely amount of such loss, and if such amount is not determinable, then we accrue the minimum in the range as the loss accrual. The determination of the outcome and loss estimates requires significant judgment on the part of management, can be highly subjective and is subject to significant change with the passage of time as more information becomes available. Estimating the ultimate impact of litigation matters is inherently uncertain, in particular because the ultimate outcome will rest on events and decisions of others that may not be within our power to control. We do not believe that any of our current litigation will have a significant adverse effect on our consolidated financial position, results of operations or liquidity; however, if amounts paid at the resolution of litigation are in excess of recorded reserve amounts, the excess could be significant in relation to results of operations for that period. For further information, see Note 24.

Accounting Developments

Accounting Developments - Accounting Standards to be Adopted in Future Periods

Revenue Recognition.  In May 2014, the FASB issued new guidance that defines how companies report revenues from contracts with customers, and also requires enhanced disclosures. The core principle of this new guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. This guidance is effective for interim and annual periods beginning after December 15, 2017. We have adopted the new guidance as of January 1, 2018 using the modified retrospective approach with a cumulative-effect adjustment to opening retained earnings of approximately $8 million. Our implementation efforts included the identification of revenue streams within the scope of the guidance, the evaluation of certain revenue contracts and education and discussion with our consolidated subsidiaries. Based on our assessment, the impact of the adoption of the new guidance does not have a material impact on our consolidated financial statements. The below focuses on our two largest consolidated subsidiaries, whose combined revenues comprise more than 92% of our Net revenues in the Consolidated Statements of Operations for the year ended December 31, 2017.

For Jefferies, as the new revenue recognition guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, and as a result, did not have an impact on the elements of its revenues most closely associated with financial instruments, including Principal transaction revenues, Interest income and Interest expense. The new revenue standard primarily impacts the following of Jefferies revenue recognition and presentation accounting policies:

• Investment Banking Revenues. Advisory fees from mergers and acquisitions engagements are recognized at a point in time when the related transaction is completed, as the performance obligation is to successfully broker a specific transaction.

• Certain Capital Markets Revenues. Revenues associated with price stabilization activities as part of a securities underwriting were historically recognized as part of Investment banking revenues. Under the new revenue standard, revenue from these activities is recognized within Principal transaction revenues, as these revenues are not considered to be within the scope of the new standard.

• Investment Banking Advisory Expenses. Historically, expenses associated with investment banking advisory assignments were deferred until reimbursed by the client, the related fee revenue is recognized or the engagement is otherwise concluded. Under the new revenue standard, expenses are deferred only to the extent they are explicitly reimbursable by the client and the related revenue is recognized at a point in time. All other investment banking advisory related expenses, including expenses incurred related to restructuring assignments, are expensed as incurred.

• Investment Banking Underwriting and Advisory Expenses. Expenses have historically been recorded net of client reimbursements and/or netted against revenues. Under the new revenue standard, all investment banking expenses will be recognized within their respective expense category on the consolidated statements of operations and any expense reimbursements will be recognized as Investment banking revenues (i.e., expenses are no longer recorded net of client reimbursements and are not netted against revenues).

• Asset Management Fees. In certain asset management fee arrangements, Jefferies and LAM receive performance-based fees, which vary with performance or, in certain cases, are earned when the return on assets under management exceed certain benchmark returns or other performance targets. Historically, performance fees have been accrued (or reversed) quarterly based on measuring performance to date versus any relevant benchmark return hurdles stated in the investment management agreement. Under the new revenue standard, performance fees are considered variable as they are subject to fluctuation (e.g., based on market performance) and/or are contingent on a future event during the measurement period (e.g., meeting a specified benchmark rate) and are recognized only to the extent it is not probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty is resolved. Accordingly, performance fee revenue will generally be recognized only at the end of the performance period to the extent that the benchmark return has been met.

National Beef earns over 95% of its revenues through the sale of beef, pork and beef by-products. Agreements with customers for these sales typically consist of the type and quantity of products to be delivered, the unit price of each product, the estimated delivery date and credit and payment terms. The transaction price is generally fixed at this time and revenue is recognized when the customer takes control of the product. The impact of the new guidance does not materially impact how revenue is recognized for this revenue stream.

Financial Instruments. In January 2016, the FASB issued new guidance that affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. The guidance is effective for annual and interim periods beginning after December 15, 2017. We do not believe the new guidance related to equity investments and the presentation and disclosure requirements of financial instruments will have a material impact on our consolidated financial statements. We have adopted the new guidance as of January 1, 2018 with a cumulative-effect increase to opening retained earnings of approximately $28 million and a corresponding decrease to Accumulated other comprehensive income. Early adoption was permitted for the accounting guidance on financial liabilities under the fair value option and we adopted this guidance in the first quarter of 2016. The adoption of the guidance on financial liabilities under the fair value option did not have a material impact on our consolidated financial statements.

Leases. In February 2016, the FASB issued new guidance that affects the accounting and disclosure requirements for leases. The FASB requires the recognition of lease assets and lease liabilities on the statement of financial condition. The guidance is effective for annual and interim periods beginning after December 15, 2018. We are currently evaluating the impact this new guidance will have on our consolidated financial statements.

Financial Instruments - Credit Losses. In June 2016, the FASB issued new guidance for estimating credit losses on certain types of financial instruments by introducing an approach based on expected losses. The guidance is effective for annual and interim periods beginning after December 15, 2019. We are currently evaluating the impact this new guidance will have on our consolidated financial statements.

Cash Flow Classifications. In August 2016, the FASB issued new guidance to reduce the diversity in practice in how certain transactions are classified in the statement of cash flows. The guidance adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The guidance is effective for annual and interim periods beginning after December 15, 2017. In November 2016, the FASB issued new guidance on restricted cash. The guidance requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. The guidance is effective for annual and interim periods beginning after December 15, 2017. We do not believe the new guidance will have a material impact on our consolidated financial statements.

Goodwill. In January 2017, the FASB issued new guidance for simplifying goodwill impairment testing. The guidance is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted. We do not believe the new guidance will have a material impact on our consolidated financial statements.

Retirement Benefits. In March 2017, the FASB issued new guidance for improving the presentation of net periodic pension costs in the statement of operations. The update also allows the service cost to be eligible for capitalization, when applicable. The guidance is effective for annual and interim periods beginning after December 15, 2017 and early adoption is permitted. We do not believe the new guidance will have a material impact on our consolidated financial statements.

Compensation. In May 2017, the FASB issued new guidance providing clarity and reducing diversity in practice and cost and complexity when accounting for a change to the terms or conditions of a share-based payment award. The guidance is effective for annual and interim periods beginning after December 15, 2017 and early adoption is permitted. We do not believe the new guidance will have a material impact on our consolidated financial statements.

Derivatives and hedging. In August 2017, the FASB issued new guidance to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. The guidance is effective for annual and interim periods beginning after December 15, 2018 and early adoption is permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements.

(1) Where fair value is calculated based on NAV, fair value has been derived from each of the funds' capital statements.

(2) This category includes investments in hedge funds that invest, long and short, in primarily equity securities in domestic and international markets in both the public and private sectors. At December 31, 2017 and 2016, 73% and 83%, respectively, of these investments are redeemable with 10 business days or less prior written notice, and 15% and 17%, respectively, are redeemable with 30 to 60 days prior written notice.

(3) This category includes investments in funds that invest in loans secured by a first trust deed on property, domestic and international public high yield debt, private high yield investments, senior bank loans, public leveraged equities, distressed debt and private equity investments. There are no redemption provisions. 

(4) This category includes investments in fund of funds that invest in various private equity funds. The investments in this category are managed by us and have no redemption provisions. These investments are gradually being liquidated or we have requested redemption, however, we are unable to estimate when these funds will be received.

(5) The investments in this category include investments in equity funds that invest in the equity of various U.S. and foreign private companies in the energy, technology, internet service and telecommunication service industries. These investments cannot be redeemed; instead distributions are received through the liquidation of the underlying assets of the funds, which are expected to liquidate in one to six years. 

(6) This category includes investments in hedge funds that invest, long and short, primarily in multi-asset securities in domestic and international markets in both the public and private sectors. At both December 31, 2017 and 2016, investments representing approximately 12% of the fair value of investments in this category are redeemable with 30 days prior written notice.

(1) Primarily classified in Investment banking revenues and Other revenues.

(2) On October 31, 2017, Jefferies sold all of its membership interests in Jefferies LoanCore for approximately $173.1 million.

(3) At December 31, 2017, 2016 and 2015, the balance reflects $30.5 million, $32.8 million and $33.7 million, respectively, related to a noncontrolling interest.

(4) At December 31, 2016, the balance reflects $95.3 million related to noncontrolling interests.

(5) As discussed further below, on November 30, 2017, we sold our interest in the general partner of the 54 Madison fund and as a result no longer control the 54 Madison investment committee. We retained two of the four seats on the investment committee and continue to have significant influence over the fund. We therefore deconsolidated the 54 Madison fund and account for our interest under the equity method of accounting.

(6) As discussed more fully in Note 4, in 2016, we amended the terms of our loan and associated rights with FXCM. Through the amendments, we converted our participation rights for a 50% voting interest in FXCM. Our term loan remains classified within Trading assets, at fair value.

(1) Under master netting agreements with our counterparties, we have the legal right of offset with a counterparty, which incorporates all of the counterparty’s outstanding rights and obligations under the arrangement. These balances reflect additional credit risk mitigation that is available by a counterparty in the event of a counterparty’s default, but which are not netted in the balance sheet because other provisions of GAAP are not met. Further, for derivative assets and liabilities, amounts netted include cash collateral paid or received.

(2) Includes securities received or paid under collateral arrangements with counterparties that could be liquidated in the event of a counterparty default and thus offset against a counterparty’s rights and obligations under the respective repurchase agreements or securities borrowing or lending arrangements.

(3) At December 31, 2017, amounts include $5,678.6 million of securities borrowing arrangements, for which we have received securities collateral of $5,516.7 million, and $1,084.4 million of repurchase agreements, for which we have pledged securities collateral of $1,115.9 million, which are subject to master netting agreements but we have not determined the agreements to be legally enforceable. At December 31, 2016, amounts include $6,337.5 million of securities borrowing arrangements, for which we have received securities collateral of $6,146.0 million, and $810.4 million of repurchase agreements, for which we have pledged securities collateral of $834.2 million, which are subject to master netting agreements but we have not determined the agreements to be legally enforceable.
