ITEM 1. BUSINESS

Stifel Financial Corp. is a Delaware corporation and a financial holding company headquartered in St. Louis. We were organized in 1983. Our principal subsidiary is Stifel, Nicolaus & Company, Incorporated (“Stifel”), a full-service retail and institutional wealth management and investment banking firm. Stifel is the successor to a partnership founded in 1890. Our other subsidiaries include Century Securities Associates, Inc. (“CSA”), an independent contractor broker-dealer firm; Keefe, Bruyette & Woods, Inc. (“KBW”), and Miller Buckfire & Co. LLC (“Miller Buckfire”), broker-dealer firms; Stifel Nicolaus Europe Limited (“SNEL”), our European subsidiary; Stifel Bank & Trust and Stifel Bank (collectively “Stifel Bancorp”), retail and commercial banks; Stifel Trust Company, N.A. and Stifel Trust Company Delaware, N.A. (collectively, “Stifel Trust”), our trust companies; and 1919 Investment Counsel, LLC  and Ziegler Capital Management, LLC (“ZCM”), asset management firms. Unless the context requires otherwise, the terms “the Company,” “our company,” “we,” and “our,” as used herein, refer to Stifel Financial Corp. and its subsidiaries.

With a 128-year operating history, we have built a diversified business serving private clients, institutional investors, and investment banking clients located across the country. Our principal activities are:

• Private client services, including securities transaction and financial planning services;

• Institutional equity and fixed income sales, trading and research, and municipal finance;

• Investment banking services, including mergers and acquisitions, public offerings, and private placements; and

• Retail and commercial banking, including personal and commercial lending programs.

Our core philosophy is based upon a tradition of trust, understanding, and studied advice. We attract and retain experienced professionals by fostering a culture of entrepreneurial, long-term thinking. We provide our private, institutional, and corporate clients quality, personalized service, with the theory that if we place clients’ needs first, both our clients and our company will prosper. Our unwavering client and employee focus have earned us a reputation as one of the nation’s leading wealth management and investment banking firms.

We have grown our business both organically and through opportunistic acquisitions. Over the past several years, we have grown substantially, primarily by completing and successfully integrating a number of acquisitions, including our acquisition of the capital markets business of Legg Mason (“LM Capital Markets”) from Citigroup in December 2005 and the following acquisitions:

• Ryan Beck Holdings, Inc. (“Ryan Beck”) and its wholly owned broker-dealer subsidiary, Ryan Beck & Company, Inc. – On February 28, 2007, we closed on the acquisition of Ryan Beck, a full-service brokerage and investment banking firm with a strong private client focus, from BankAtlantic Bancorp, Inc.

Business Segments

We operate in the following segments: Global Wealth Management, Institutional Group, and Other. For a discussion of the financial results of our segments, see Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Segment Analysis.”

Narrative Description of Business

As of December 31, 2018, we employed over 7,500 associates, including 2,301 financial advisors, of which 101 are independent contractors. Through our broker-dealer subsidiaries, we provide securities-related financial services to customers from the United States and Europe. Our customers include individuals, corporations, municipalities, and institutions. We have customers throughout the United States, with a growing presence in the United Kingdom and Europe. No single client accounts for a material percentage of any segment of our business. Our inventory, which we believe is of modest size and intended to turn over quickly, exists to facilitate order flow and support the investment strategies of our clients. The inventory of securities held to facilitate customer trades and our market-making activities is sensitive to market movements. Furthermore, our balance sheet is highly liquid, without material holdings of securities that are difficult to value or remarket. We believe that our broad platform, fee-based revenues, and strong distribution network position us well to take advantage of current trends within the financial services sector.

GLOBAL WEALTH MANAGEMENT

We provide securities transaction, brokerage, and investment services to our clients through the consolidated Stifel branch system. We have made significant investments in personnel and technology to grow the Private Client Group over the past eleven years.

Consolidated Stifel Branch System

At December 31, 2018, the Private Client Group had a network of 2,200 financial advisors located in 369 branch offices in 45 states and the District of Columbia. In addition, we have 101 independent contractors.

Our financial advisors provide a broad range of investments and services to our clients, including financial planning services. We offer equity securities; taxable and tax-exempt fixed income securities, including municipal, corporate, and government agency securities; preferred stock; and unit investment trusts. We also offer a broad range of externally managed fee-based products. In addition, we offer insurance and annuity products and investment company shares through agreements with numerous third-party distributors. We encourage our financial advisors to pursue the products and services that best fit their clients’ needs and that they feel most comfortable recommending. Our private clients may choose from a traditional, commission-based structure or fee-based money management programs. In most cases, commissions are charged for sales of investment products to clients based on an established commission schedule. In certain cases, varying discounts may be given based on relevant client or trade factors determined by the financial advisor.

Our independent contractors, who operate in our CSA business, provide the same types of financial products and services to its private clients as does Stifel. Under their contractual arrangements, these independent contractors may also provide accounting services, real estate brokerage, insurance, or other business activities for their own account. Independent contractors are responsible for all of their direct costs and are paid a larger percentage of commissions to compensate them for their added expenses. CSA is an introducing broker-dealer and, as such, clears its transactions through Stifel.

Customer Financing

Client securities transactions are effected on either a cash or margin basis. When securities are purchased on a margin basis, the customer deposits less than the full cost of the security in their account. We make a loan to the customer for the balance of the purchase price. Such loans are collateralized by the purchased securities. The amounts of the loans are subject to the margin requirements of Regulation T of the Board of Governors of the Federal Reserve System, Financial Industry Regulatory Authority, Inc. (“FINRA”) margin requirements, and our internal policies, which usually are more restrictive than Regulation T or FINRA

3

requirements. In permitting customers to purchase securities on margin, we are subject to the risk of a market decline, which could reduce the value of our collateral below the amount of the customers’ indebtedness.

We offer securities-based lending through Stifel Bancorp, which allows clients to borrow money against the value of qualifying securities for any suitable purpose other than purchasing, trading, or carrying marketable securities or refinancing margin debt. The loan requirements are subject to Regulation U of the Board of Governors of the Federal Reserve System (“Regulation U”) and our internal policies, which are typically more restrictive than Regulation U. We establish approved lines and advance rates against qualifying securities and monitor limits daily and, pursuant to such guidelines, require customers to deposit additional collateral or reduce debt positions, when necessary. Factors considered in the review of securities-based lending are the amount of the loan, the degree of concentrated or restricted positions, and the overall evaluation of the portfolio to ensure proper diversification, or, in the case of concentrated positions, appropriate liquidity of the underlying collateral or potential hedging strategies. Underlying collateral for securities-based loans is reviewed with respect to the liquidity of the proposed collateral positions, valuation of securities, historic trading range, volatility analysis, and an evaluation of industry concentrations.

Asset Management

Our asset management business offers specialized investment management solutions for institutions, private clients, and investment advisors. Revenues for this segment are primarily generated by the investment advisory fees related to asset management services provided for individual and institutional investment portfolios, along with mutual funds. Investment advisory fees are earned on assets held in managed or non-discretionary asset-based programs. These fees are computed based on balances either at the beginning of the quarter, the end of the quarter, or average daily assets. Fees from private client investment portfolios and institutional fees are typically based on asset values at the end of the prior period. Asset balances are impacted by both the performance of the market and sales and redemptions of client accounts/funds. Rising markets have historically had a positive impact on investment advisory fee revenues as existing accounts increase in value, and individuals and institutions may commit incremental funds in rising markets. No single client accounts for a material percentage of this segment’s total business.

Stifel Bancorp

In April 2007, we completed the acquisition of First Service, a St. Louis-based full-service bank, which now operates as Stifel Bank & Trust. On August 31, 2018, the Company completed the acquisition of BBI and its wholly owned subsidiary, The Business Bank of St. Louis, a full-service banking facility with approximately $600.0 million in assets that operates from a single location. The Business Bank of St. Louis now operates as Stifel Bank. Business Bancshares, Inc., which operates as the holding company for Stifel Bank & Trust, and its wholly owned subsidiaries, and Stifel Bank (collectively “bank subsidiaries”) was renamed “Stifel Bancorp, Inc.” Our bank subsidiaries are reported in the Global Wealth Management segment. We have grown retail and commercial bank assets from $145.6 million on the acquisition date to $17.8 billion at December 31, 2018. Through our bank subsidiaries, we offer retail and commercial banking services to private and corporate clients, including personal loan programs, such as fixed and variable mortgage loans, home equity lines of credit, personal loans, loans secured by CDs or savings, and securities-based loans, as well as commercial lending programs, such as small business loans, commercial real estate loans, lines of credit, credit cards, term loans, and inventory and receivables financing, in addition to other banking products. We believe our bank subsidiaries not only help us serve our private clients more effectively by offering them a broader range of services, but also enable us to better utilize our private client cash balances held which are swept to our bank subsidiaries, which is their primary source of funding.

INSTITUTIONAL GROUP

The Institutional Group segment includes research, equity and fixed income institutional sales and trading, investment banking, public finance, and syndicate.

Research

Our research department publishes research across multiple industry groups and provides our clients with timely, insightful, and actionable research, aimed at improving investment performance.

Institutional Sales and Trading

Our equity sales and trading team distributes our proprietary equity research products and communicates our investment recommendations to our client base of institutional investors, executes equity trades, sells the securities of companies for which we act as an underwriter, and makes a market in securities. In our various sales and trading activities, we take a focused approach to serving our clients by maintaining inventory to facilitate order flow and support the investment strategies of our institutional fixed income clients, as opposed to seeking trading profits through proprietary trading. Our equity sales and trading teams are located in various cities in the United States, as well as Geneva, Zurich, London, and Madrid.

The fixed income institutional sales and trading group is comprised of taxable and tax-exempt sales departments. Our institutional sales and trading group executes trades with diversification across municipal, corporate, government agency, and mortgage-backed securities.

4

Investment Banking

Our investment banking activities include the provision of financial advisory services principally with respect to mergers and acquisitions and the execution of public offerings and private placements of debt and equity securities. The investment banking group focuses on middle-market companies as well as on larger companies in targeted industries where we have particular expertise, which include real estate, financial services, healthcare, aerospace/defense and government services, telecommunications, transportation, energy, business services, consumer services, industrial, technology, and education.

Our syndicate department coordinates marketing, distribution, pricing, and stabilization of our managed equity and debt offerings. In addition, the department coordinates our underwriting participations and selling group opportunities managed by other investment banking firms.

Public Finance

Our public finance group acts as an underwriter and dealer in bonds issued by states, cities, and other political subdivisions and acts as manager or participant in offerings managed by other firms.

OTHER SEGMENT

The Other segment includes interest income from stock borrow activities, unallocated interest expense, interest income and gains and losses from investments held, compensation expense associated with the expensing of restricted stock awards with no continuing service requirements as a result of recent acquisitions and to actions taken by the Company in response to the Tax Regulation enacted in the fourth quarter of 2017, amortization of stock-based awards for certain administrative employees, and all unallocated overhead costs associated with the execution of orders; processing of securities transactions; custody of client securities; receipt, identification, and delivery of funds and securities; compliance with regulatory and legal requirements; internal financial accounting and controls; and general administration and acquisition charges.

BUSINESS CONTINUITY

We have developed a business continuity plan which is designed to permit continued operation of business-critical functions in the event of disruptions to our St. Louis, Missouri, headquarters facility as well as other critical functional areas of the firm. Several critical business functions are supported by outside vendors who maintain backup and recovery in line with our internal needs and capabilities. We periodically participate in testing of these backup and recovery functions. Likewise, the business functions we support internally can be supported without the St. Louis headquarters through a combination of redundant computer facilities in other east and west coast data centers and from certain branch locations which can connect to our third-party securities processing vendor through its primary or redundant facilities. Systems have been designed so that we can route critical processing activity and functions to alternate locations, which can be staffed with relocated personnel as appropriate.

GROWTH STRATEGY

We believe our strategy for growth will allow us to increase our revenues and to expand our role with clients as a valued partner. In executing our growth strategy, we take advantage of the consolidation among mid-tier firms, which we believe provides us opportunities in our global wealth and institutional group segments. We do not create specific growth or business plans for any particular type of acquisition, focus on specific firms, or geographic expansion, nor do we establish quantitative goals, such as intended numbers of new hires or new office openings; however, our corporate philosophy has always been to be in a position to take advantage of opportunities as they arise, while maintaining sufficient levels of capital. We intend to pursue the following strategies with discipline:

• Further expand our private client footprint in the U.S. We have expanded the number of our private client branches from 39 at December 31, 1997 to 369 at December 31, 2018, and our branch-based financial advisors from 262 to 2,200 over the same period. In addition, assets under management have grown from $11.7 billion at December 31, 1997 to $269.9 billion at December 31, 2018. Through organic growth and acquisitions, we have built a strong footprint nationally. Over time, we plan to further expand our domestic private client footprint. We plan on achieving this through recruiting experienced financial advisors with established client relationships and continuing to selectively consider acquisition opportunities as they may arise.

• Further expand our institutional business both domestically and internationally. Our institutional equity business is built upon the premise that high-quality fundamental research is not a commodity. The growth of our business has been fueled by the effective partnership of our highly rated research and institutional sales and trading teams. We have identified opportunities to expand our research capabilities by taking advantage of market disruptions. As of December 31, 2018, our research department was ranked the largest research department, as measured by domestic equities under coverage, by StarMine. Our goal is to further monetize our research platform by adding additional institutional sales and trading teams and by placing a greater emphasis on client management.

5

• Grow our investment banking business. By leveraging our industry expertise, our product knowledge, our research platform, our experienced associates, our capital markets strength, our middle-market focus, and our private client network, we intend to grow our investment banking business. The merger with TWPG in 2010, our acquisition of Miller Buckfire in 2012, the merger with KBW in 2013, the acquisitions of De La Rosa, Oriel, and Merchant Capital in 2014, and the acquisitions of Eaton Partners and ISM in 2016 have accelerated the growth of our investment banking business through expanded industry, product, and geographic coverage, including capital-raising for start-up companies, particularly from the venture community. We believe our position as a middle-market-focused investment bank with broad-based and respected research will allow us to take advantage of opportunities in the middle market and continue to align our investment banking coverage with our research footprint.

• Focus on asset generation within Stifel Bancorp by offering banking services to our clients. We believe the banking services provided through Stifel Bancorp strengthens our existing client relationships and helps us recruit financial advisors seeking to provide a full range of services to their private clients. We intend to continue focusing on the sale of banking products and services to our private and corporate clients.

• Approach acquisition opportunities with discipline. Over the course of our operating history, we have demonstrated our ability to identify, effect, and integrate attractive acquisition opportunities. We believe the current environment and market dislocation will continue to provide us with the ability to thoughtfully consider acquisitions on an opportunistic basis.

COMPETITION

We compete with other securities firms, some of which offer their customers a broader range of brokerage services, have substantially greater resources, and may have greater operating efficiencies. In addition, we face increasing competition from other financial institutions, such as commercial banks, online service providers, and other companies offering financial services. The Financial Modernization Act, signed into law in late 1999, lifted restrictions on banks and insurance companies, permitting them to provide financial services once dominated by securities firms. In addition, consolidation in the financial services industry may lead to increased competition from larger, more diversified organizations.

As we enter our 129^th year in business, we continue to rely on the expertise acquired in our market area, our personnel, and our equity capital to operate in the competitive environment.

REGULATION

Financial Holding Company Regulation

Under U.S. law, we are a bank holding company that has elected to be a financial holding company under the Bank Holding Company Act of 1956, as amended (“BHCA”). Consequently, our company and its business activities are subject to the supervision, examination, and regulation of the Federal Reserve Board. The BHCA and other federal laws subject bank and financial holding companies to particular restrictions on the types of activities in which they may engage and to a range of supervisory requirements and activities, including regulatory enforcement actions for violations of laws and regulations. Supervision and regulation of bank holding companies, financial holding companies, and their subsidiaries are intended primarily for the protection of depositors and other clients of banking subsidiaries, the deposit insurance fund of the Federal Deposit Insurance Corporation (“FDIC”), and the banking system as a whole, but not for the protection of stockholders or other creditors.

As a financial holding company, we are permitted: (1) to engage in other activities that the Federal Reserve Board, working with the Secretary of the Treasury, determines to be financial in nature, incidental to an activity that is financial in nature, or complementary to a financial activity and that do not pose a substantial risk to the safety and soundness of depository institutions or the financial system generally, or (2) to acquire shares of companies engaged in such activities. We may not, however, directly or indirectly acquire the ownership or control of more than 5% of any class of voting shares, or substantially all of the assets, of a bank holding company or a bank without the prior approval of the Federal Reserve Board.

In order to maintain our status as a financial holding company, we must remain “well capitalized” and “well managed” under applicable regulations. Failure to meet one or more of the requirements would mean, depending on the requirements not met, that we could not undertake new activities, make acquisitions other than those permitted generally for bank holding companies, or continue certain activities.

Rules and Regulations Resulting From the Dodd-Frank Act

Since 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) has imposed significant new regulatory and compliance requirements, although some provisions of the Dodd-Frank Act remain subject to further rulemaking proceedings and studies and will take effect over the next several years.

As a result of the Dodd-Frank Act and its implementing regulations, we continue to experience a period of notable change in financial regulation and supervision. These changes could have a significant impact on how we conduct our business. Many regulatory or supervisory policies remain in a state of flux and may be subject to amendment in the near future, particularly due to the President’s executive order issued in February 2017 to evaluate the current regulatory framework, particularly as it relates to the financial services industry. As a result, we cannot specifically quantify the impact that such regulatory or supervisory requirements will have on our

business and operations (see Item 1A “Risk Factors” within this report for further discussion of the potential future impact on our operations). In the following sections, we highlight certain of the more significant changes brought about as a result of the Dodd-Frank Act and related measures.

CFPB Oversight

The Consumer Financial Protection Bureau (“CFPB”) has supervisory and enforcement powers under several consumer protection laws, including the: (i) Equal Credit Opportunity Act; (ii) Truth in Lending Act; (iii) Real Estate Settlement Procedures Act; (iv) Fair Credit Reporting Act; (v) Fair Debt Collection Act; (vi) Consumer Financial Privacy provisions of the Gramm-Leach-Bliley Act and (vii) unfair, deceptive or abusive acts or practices under section 1031 of the Dodd-Frank Act. The CFPB has supervisory authority over Stifel Bank & Trust for its compliance with the various federal consumer protection laws. The CFPB also has authority to promulgate regulations, issue orders, draft policy statements, conduct examinations, and bring enforcement actions. The creation of the CFPB has led to enhanced enforcement of consumer protection laws. To the extent that, as a result of such heightened scrutiny and oversight, we become the subject of any enforcement activity, we may be required to pay fines, incur penalties, or engage in certain remediation efforts.

Stress Tests

On May 24, 2018, the Economic Growth, Regulatory Relief, and Consumer Protection Act was signed into law, making certain limited amendments to the Dodd-Frank Act, as well as certain targeted modifications to other post-financial crisis regulations. Among other things, the law raises the asset thresholds for Dodd-Frank Act company-run stress testing, liquidity coverage and living will requirements for bank holding companies to $250 billion, subject to the ability of the Federal Reserve to apply such requirements to institutions with assets of $100 billion or more to address financial stability risks or safety and soundness concerns. On July 6, 2018, the Federal Reserve, the Office of the Comptroller of the Currency (“OCC”), and the FDIC issued a joint interagency statement regarding the impact of the Economic Growth, Regulatory Relief, and Consumer Protection Act. As a result of this statement and the Economic Growth, Regulatory Relief, and Consumer Protection Act, our bank subsidiaries are no longer subject to Dodd-Frank Act stress testing requirements.

The Volcker Rule

We are subject to the Volcker Rule, a provision of the Dodd-Frank Act, which generally prohibits, subject to exceptions, insured depository institutions, bank holding companies and their affiliates (together, “banking entities”) from engaging in proprietary trading and limits investments in and relationships with hedge funds and private equity funds (“covered funds”). Banking entities must establish a Volcker Rule-specific compliance program. We have adopted a program, which is designed to be effective in ensuring compliance with the Volcker Rule; however, in connection with their examinations, regulators will assess the sufficiency and adequacy of our program.

We maintain a number of private equity investments, some of which meet the definition of covered funds under the Volcker Rule. The conformance period for compliance with the rule with respect to investments in covered funds was July 2017; however, banking entities were able to apply for an extension to provide up to an additional five years to conform investments in certain illiquid funds. The majority of our covered fund investments meet the criteria to be considered an illiquid fund under the Volcker Rule and we received approval from the Fed to continue to hold such investments until July 2022. The extension of the conformance deadline provides us with additional time to realize the value of these investments in due course and to execute appropriate strategies to comply with the Volcker Rule at such time. However, our current focus is on the divestiture of our existing portfolio.

On June 5, 2018, the five federal regulatory agencies having oversight over the Volcker Rule announced publication of proposed amendments to the rule. The notice of proposed rulemaking contains certain revisions to the Volcker Rule’s covered fund restrictions. We are evaluating the proposal to determine the impact such proposal will have, if any, if it becomes effective.

U.S. Capital Rules and Basel III

Our company, as a bank and financial holding company, and our bank subsidiaries are subject to regulation, including capital requirements, by the Federal Reserve. Stifel Bank is subject to various regulatory capital requirements administered by the Federal Reserve and the Missouri Division of Finance. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our company’s and Stifel Bancorp’s financial statements.

The OCC, the Federal Reserve, and the FDIC released final U.S. rules implementing the Basel III capital framework developed by the Basel Committee on Banking Supervision and certain Dodd-Frank Act and other capital provisions and updated the prompt corrective action framework to reflect the new regulatory capital minimums (the “U.S. Basel III Rules”). The U.S. Basel III Rules: (i) increase the quantity and quality of regulatory capital; (ii) establish a capital conservation buffer; and (iii) make changes to the calculation of risk-weighted assets. The U.S. Basel III Rules became effective for our company and its bank subsidiaries on January 1, 2015, subject to applicable phase-in periods. Based on our current analyses, our company and its bank subsidiaries are well-capitalized. However, the increased capital requirements could restrict our ability to grow or require us to raise additional capital. As a result, our business,

7

results of operations, financial condition, or prospects could be adversely affected. See Item 1A, “Risk Factors,” within this Form 10-K for more information.

Failure to meet minimum capital requirements can trigger discretionary, and in certain cases, mandatory actions by regulators that could have a direct material effect on the financial results of Stifel Bank & Trust and Stifel Bank. Under capital adequacy guidelines, Stifel Bank & Trust and Stifel Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification for Stifel Bank & Trust and Stifel Bank are also subject to the qualitative judgments of U.S. regulators based on components of capital, risk-weightings of assets, off-balance sheet transactions, and other factors. Quantitative measures established by federal banking regulations to ensure capital adequacy require that Stifel Bank & Trust and Stifel Bank maintain minimum amounts and ratios of: (i) Common Equity Tier 1, Tier 1 and Total capital to risk-weighted assets; (ii) Tier 1 capital to average assets; and (iii) capital conservation buffers. See Note 19 of the Notes to the Consolidated Financial Statements of this Form 10-K for further information.

Money Market Reform

The Securities and Exchange Commission (“SEC”) adopted amendments to the rules that govern money market mutual funds. The amendments make structural and operational reforms to address risks of excessive withdrawals over relatively short time frames by investors from money market funds, while preserving the benefits of the funds. We do not sponsor any money market funds. We utilize funds sponsored by third parties in limited circumstances for our own investment purposes as well as to offer our clients as one of several cash sweep alternatives.

Fiduciary Duty Standard

In April 2016, the U.S. Department of Labor (the “DOL”) issued a final regulation (the “DOL Rule”) expanding the definition of who is deemed an “investment advice fiduciary” under the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), as a result of giving investment advice to a “plan,” “plan participant” or “beneficiary,” as well as under the Internal Revenue Code for individual retirement arrangements and non-ERISA plans (collectively, “qualified plans”). However, in June 2018, the U.S. Court of Appeals for the Fifth Circuit vacated the DOL Rule, and thus it is no longer in effect.

Separately, pursuant to the Dodd-Frank Act, the SEC was charged with considering whether broker-dealers should be subject to a standard of care similar to the fiduciary standard applicable to registered investment advisors. In April 2018, the SEC proposed Regulation Best Interest. The proposed Regulation Best Interest would, among other things, require a broker-dealer to act in the best interest of a retail customer when making a recommendation of any securities transaction or investment strategy involving securities to such customer. We anticipate the adoption of any new rule by the SEC will require us to review and possibly modify our compliance activities, which may lead to additional costs. In addition, state laws that impose a fiduciary duty also may require monitoring, as well as require that we undertake additional compliance measures.

Holding company support

Under the Dodd-Frank Act, the Federal Reserve must require that bank holding companies, such as our company, serve as a source of financial strength for any subsidiary depository institution. The term “source of financial strength” is defined as the ability of a company to provide financial assistance to its insured depository institution subsidiaries in the event of financial distress at such subsidiaries. Under this requirement, we in the future could be required to provide financial assistance to its bank subsidiaries should they experience financial distress.

Other regulations applicable to our operations

The SEC is the federal agency charged with administration of the federal securities laws in the U.S. Our broker-dealer subsidiaries are subject to SEC regulations relating to their business operations, including sales and trading practices, public offerings, publication of research reports, use and safekeeping of client funds and securities, capital structure, record-keeping, privacy requirements, and the conduct of directors, officers and employees. Financial services firms are also subject to regulation by state securities commissions in those states in which they conduct business.

Broker-dealers are required to maintain the minimum net capital deemed necessary to meet their continuing commitments to customers and others, and are required to keep their assets in relatively liquid form. These rules also limit the ability of broker-dealers to transfer capital to parent companies and other affiliates. The SEC has adopted amendments to its financial stability rules, many of which became effective as of October 2013 and are applicable to our broker-dealer subsidiaries, including changes to the: (i) net capital rule; (ii) customer protection rule; (iii) record-keeping rules; and (iv) notification rules.

Financial services firms are subject to regulation by various foreign governments, securities exchanges, central banks and regulatory bodies, particularly in those countries where they have established offices. Outside of the U.S., we have additional offices primarily in Canada and Europe and are subject to regulations in those areas. Much of the regulation of broker-dealers in the U.S. and Canada, however, has been delegated to self-regulatory organizations (“SROs”) (i.e., FINRA), the Investment Industry Regulatory Organization of Canada and securities exchanges). These SROs adopt and amend rules for regulating the industry, subject to the approval of government agencies. These SROs also conduct periodic examinations of member broker-dealers.

8

The SEC, SROs and state securities regulators may conduct administrative proceedings that can result in censure, fine, suspension or expulsion of a broker-dealer, its officers or employees. Such administrative proceedings, whether or not resulting in adverse findings, can require substantial expenditures and may adversely impact the reputation of a broker-dealer.

Our U.S. broker-dealer subsidiaries are subject to the Securities Investor Protection Act (“SIPA”) and are required by federal law to be members of the Securities Investors Protection Corporation (“SIPC”). The SIPC was established under SIPA, and oversees the liquidation of broker-dealers during liquidation or financial distress. The SIPC fund provides protection for cash and securities held in client accounts up to $500,000 per client, with a limitation of $250,000 on claims for cash balances. For further discussion of our net capital requirements, see Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources.”

Our investment advisory operations, including the mutual funds that we sponsor, are also subject to extensive regulation in the U.S. Our U.S. asset managers are registered as investment advisers with the SEC under the Investment Advisers Act of 1940 as amended, and are also required to make notice filings in certain states. Virtually all aspects of our asset management business are subject to various federal and state laws and regulations. These laws and regulations are primarily intended to benefit the asset management clients.

U.S. federal law establishes minimum federal standards for financial privacy by, among other provisions, requiring financial institutions to adopt and disclose privacy policies with respect to consumer information and setting forth certain limitations on disclosure to third parties of consumer information. U.S. state law and regulations adopted under U.S. federal law impose obligations on our company and its subsidiaries for protecting the security, confidentiality and integrity of client information, and require notice of data breaches to certain U.S. regulators, and in some cases, to clients. The General Data Protection Regulation (“GDPR”) imposes additional requirements for companies that collect or store personal data of European Union residents. GDPR expands the scope of the EU data protection law to all foreign companies processing personal data of EU residents, imposes a strict data protection compliance regime, and includes new rights. We have adopted and disseminated privacy policies, and communicate required information relating to financial privacy and data security, in accordance with applicable law.

In Europe, the Markets in Financial Instruments Regulation and a revision of the Markets in Financial Instruments Directive (together, “MiFID II”), generally took effect on January 3, 2018, and introduced comprehensive, new trading and market infrastructure reforms in the European Union, including new trading venues, enhancements to pre- and post-trading transparency, and additional investor protection requirements, among others. We have made changes to our European operations, including systems and controls, in order to be in compliance with MiFID II.

Central banks around the world, including the Federal Reserve, have commissioned working groups of market participants and official sector representatives with the goal of finding suitable replacements for the London Interbank Offered Rate (“LIBOR”) based on observable market transactions. It is expected that a transition away from the widespread use of LIBOR to alternative rates will occur over the course of the next few years. Although the full impact of a transition, including the potential or actual discontinuance of LIBOR publication, remains unclear, this change may have an adverse impact on the value of, return on and trading markets for a broad array of financial products, including any LIBOR-based securities, loans and derivatives that are included in our financial assets and liabilities. A transition away from LIBOR may also require extensive changes to the contracts that govern these LIBOR-based products, as well as our systems and processes.

Our non-U.S. subsidiaries are subject to applicable laws and regulations of the jurisdictions in which they operate.

Our European subsidiary, SNEL, is subject to the regulatory supervision and requirements of the Financial Conduct Authority (“FCA”) in the United Kingdom and is a member of the London Stock Exchange. The FCA exercises broad supervisory and disciplinary powers that include the power to temporarily or permanently revoke authorization to conduct a regulated business upon breach of the relevant regulations, suspend approved persons, and impose fines (where applicable) on both regulated businesses and their approved persons. SNEL operates representative offices in Geneva and Zurich, Switzerland and has a branch office in Madrid, Spain. In addition to the FCA, these offices are subject to the local regulations of their respective jurisdictions. SNEL holds a number of FCA-passporting rights to engage in Markets in Financial Instruments Directive-related business in Europe.

As a public company whose common stock is listed on the New York Stock Exchange (“NYSE”) and the Chicago Stock Exchange (“CHX”), we are subject to corporate governance requirements established by the SEC, NYSE, and CHX, as well as federal and state law. Under the Sarbanes-Oxley Act of 2002 (the “Act”), we are required to meet certain requirements regarding business dealings with members of the Board of Directors, the structure of our Audit and Compensation Committees, ethical standards for our senior financial officers, implementation of an internal control structure and procedures for financial reporting, and additional responsibilities regarding financial statements for our Chief Executive Officer and Chief Financial Officer and their assessment of our internal controls over financial reporting. Compliance with all aspects of the Act, particularly the provisions related to management's assessment of internal controls, has imposed additional costs on our company, reflecting internal staff and management time, as well as additional audit fees since the Act went into effect.

Bank Secrecy Act and USA PATRIOT Act of 2001

9

The Bank Secrecy Act and the USA PATRIOT Act of 2001 (“Patriot Act”) and requirements administered by the Financial Crimes Enforcement Network (“FinCEN”) require financial institutions, among other things, to implement a risk-based program reasonably designed to prevent money laundering and to combat the financing of terrorism, including through suspicious activity and currency transaction reporting, compliance, record-keeping and initial and on-going due diligence on customers. The Patriot Act also contains financial transparency laws and enhanced information collection tools and enforcement mechanisms for the U.S. government, including: due diligence and record-keeping requirements for private banking and correspondent accounts; standards for obtaining and verifying customer identification at account opening; and rules to produce certain records upon request of a regulator or law enforcement and to promote cooperation among financial institutions, regulators, and law enforcement in identifying parties that may be involved in terrorism, money laundering and other crimes. In May 2016, FinCEN issued a new rule that, since May 2018, has required certain financial institutions, including our U.S. bank and broker-dealer subsidiaries, to obtain certain beneficial ownership information from legal entity clients. Failure to meet the requirements of the Bank Secrecy Act, the Patriot Act or FinCEN can lead to supervisory actions including fines.

ITEM 1A. RISK FACTORS

Our operations and financial results are subject to various risks and uncertainties, including those described below, which could adversely affect our business, financial condition, results of operations, liquidity and the trading price of our common stock. The list of risk factors provided in the following sections is not exhaustive; there may be factors not discussed in the following sections or in this Form 10-K that adversely impact our results of operations, harm our reputation or inhibit our ability to generate new business prospects. We may amend or supplement these risk factors from time to time in other reports we file with the SEC.

RISKS RELATED TO OUR BUSINESS AND INDUSTRY

Damage to our reputation could damage our businesses.

Maintaining our reputation is critical to attracting and maintaining customers, investors, and employees. If we fail to address, or appear to fail to address, issues that may give rise to reputational risk, we could significantly harm our business prospects. These issues may include, but are not limited to, any of the risks discussed in this Item 1A, including appropriately dealing with potential conflicts of interest, legal and regulatory requirements, ethical issues, money laundering, cybersecurity and privacy, record keeping, and sales and trading practices, the failure to sell securities we have underwritten at anticipated price levels, and the proper identification of the legal, reputational, credit, liquidity, and market risks inherent in our products. Failure to maintain appropriate service and quality standards, or a failure or perceived failure to treat customers fairly can result in customer dissatisfaction, litigation, and heightened regulatory scrutiny, all of which can lead to lost revenue, higher operating costs, and reputational harm. Negative publicity about us, whether or not true, may also harm our future business prospects.

We are affected by domestic and international macroeconomic conditions that impact the global financial markets.

We are engaged in various financial services businesses. As such, we are affected by domestic and international macroeconomic and political conditions, including economic output levels, interest and inflation rates, employment levels, prices of commodities, consumer confidence levels, and fiscal and monetary policy. For example, Federal Reserve policies determine, in large part, the cost of funds for lending and investing and the return earned on those loans and investments. The market impact from such policies also can decrease materially the value of certain of our financial assets, most notably debt securities. Changes in Fed policies are beyond our control and, consequently, the impact of these changes on our activities and results of our operations are difficult to predict.

12

Macroeconomic conditions also may directly and indirectly impact a number of factors in the global financial markets that may be detrimental to our operating results, including trading levels, investing, and origination activity in the securities markets, security valuations, the absolute and relative level and volatility of interest and currency rates, real estate values, the actual and perceived quality of issuers and borrowers, and the supply of and demand for loans and deposits.

While we have recently experienced an operating environment that has been favorable for many of our businesses, at times over the last several years we have experienced operating cycles during weak and uncertain U.S. and global economic conditions. If we were to experience a period of sustained downturns in the securities markets, a return to very low levels of short-term interest rates, credit market dislocations, reductions in the value of real estate, an increase in mortgage and other loan delinquencies, and other negative market factors, our revenues could be significantly impaired.

We could experience a decline in commission revenue from a lower volume of trades we execute for our clients, a decline in fees from reduced portfolio values of securities managed on behalf of our clients, a reduction in revenue from capital markets and advisory transactions due to lower activity, increased credit provisions and charge-offs, losses sustained from our customers’ and market participants’ failure to fulfill their settlement obligations, reduced net interest earnings, and other losses. Periods of reduced revenue and other losses could lead to reduced profitability because certain of our expenses, including, but not limited to, our interest expense on debt, rent, facilities and salary expenses are fixed and our ability to reduce them over short time periods is limited.

U.S. markets may also be impacted by political and civil unrest occurring in other parts of the world. Concerns about the European Union (“EU”), including Britain’s notice to the European Council of its decision to exit the EU (“Brexit”) and the stability of the EU’s sovereign debt, have caused uncertainty and disruption for financial markets globally. Continued uncertainties loom over the outcome of the EU’s financial support programs. It is possible that other EU member states may experience financial troubles in the future, or may choose to follow Britain’s lead and leave the EU. Any negative impact on economic conditions and global markets from these developments could adversely affect our business, financial condition and liquidity.

We may be impacted by budget pressures affecting U.S. state and local governments, as well as negative trends in the housing and labor markets. Investor concerns regarding these trends could potentially reduce the number and size of transactions in which we participate and, in turn, reduce our fixed income investment banking revenues. In addition, such factors could potentially have an adverse effect on the value of the municipal securities we hold in our trading securities portfolio.

We are affected primarily by economic conditions in the U.S. Market conditions in the U.S. can be assessed through the following metrics: the level and volatility of interest rates; unemployment and under-employment rates; real estate prices; consumer confidence levels and changes in consumer spending; and the number of personal bankruptcies, among others. Deterioration of market conditions can diminish loan demand, lead to an increase in mortgage and other loan delinquencies, affect loan repayment performance and result in higher reserves and net charge-offs, which can adversely affect our earnings.

Lack of liquidity or access to capital could impair our business and financial condition.

We must maintain appropriate liquidity levels. Our inability to maintain adequate liquidity and readily available access to the credit and capital markets could have a significant negative effect on our financial condition. If liquidity from our brokerage or banking operations is inadequate or unavailable, we may be required to scale back or curtail our operations, including limiting our efforts to recruit additional financial advisors, selling assets at unfavorable prices, and cutting or eliminating dividend payments. Our liquidity could be negatively affected by the inability of our subsidiaries to generate cash in the form of dividends from earnings, regulatory changes to the liquidity or capital requirements applicable to our subsidiaries that may prevent us from upstreaming cash to the parent company, limited or no accessibility to credit markets for secured and unsecured borrowings by our subsidiaries, diminished access to the capital markets for our company, and other commitments or restrictions on capital as a result of adverse legal settlements, judgments, or regulatory sanctions. Furthermore, as a bank holding company, we may become subject to prohibitions or limitations on our ability to pay dividends and/or repurchase our stock. Certain of our regulators have the authority, and under certain circumstances, the duty, to prohibit or to limit dividend payments by regulated subsidiaries to their parent.

The availability of financing, including access to the credit and capital markets, depends on various factors, such as conditions in the debt and equity markets, the general availability of credit, the volume of securities trading activity, the overall availability of credit to the financial services sector and our credit ratings. Our cost of capital and the availability of funding may be adversely affected by illiquid credit markets and wider credit spreads. Additionally, lenders may from time to time curtail, or even cease to provide, funding to borrowers as a result of future concerns over the strength of specific counterparties, as well as the stability of markets generally. See Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources,” in this Form 10-K for additional information on liquidity and how we manage our liquidity risk.

A downgrade in our credit ratings could have a material adverse effect on our operations, earnings, and financial condition.

If our credit ratings were downgraded, or if rating agencies indicate that a downgrade may occur, our business, financial position, and results of operations could be adversely affected, perceptions of our financial strength could be damaged, and as a result, adversely affect our client relationships. Such a change in our credit ratings could also adversely affect our liquidity and competitive position, increase our borrowing costs, limit our access to the capital markets, trigger obligations under certain financial agreements, or

13

decrease the number of investors, clients and counterparties willing or permitted to do business with or lend to us, thereby curtailing our business operations and reducing profitability.

We may not be able to obtain additional outside financing to fund our operations on favorable terms, or at all. The impact of a credit rating downgrade to a level below investment grade would result in our breaching provisions in our credit agreements, and may result in decreased levels of available credit or a request for immediate payment.

A credit rating downgrade would also result in the Company incurring a higher commitment fee on any unused balance on its revolving credit facilities, in addition to triggering a higher interest rate applicable to any borrowings outstanding on the line as of and subsequent to such downgrade (see Note 11 of the Notes to Consolidated Financial Statements of this Form 10-K for information on the Company’s credit facilities).

Our ability to attract and retain senior professionals, qualified financial advisors, and other associates is critical to the continued success of our business.

Our ability to develop and retain our clients depends on the reputation, judgment, business generation capabilities, and skills of our senior professionals, and the members of our executive team, as well as employees and financial advisors. 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. Competitive pressures we experience 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 recruiting and 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. In particular, our financial results may be adversely affected by the costs we incur in connection with any upfront loans or other incentives we may offer to newly recruited financial advisors and other key personnel.

To the extent we have compensation targets, we may not be able to retain our employees, which could result in increased recruiting expense or result in our recruiting additional employees at compensation levels that are not within our target range. In particular, our financial results may be adversely affected by the costs we incur in connection with any upfront loans or other incentives we may offer to newly recruited financial advisors and other key personnel. If we were to lose the services of any of our investment bankers, senior equity research, sales and trading professionals, asset managers, or executive officers to a competitor or otherwise, 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 senior 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 generally require that we incur compensation and benefits expense before generating additional revenues.

Moreover, companies in our industry whose employees accept positions with competitors frequently claim that those competitors have engaged in unfair hiring practices. We have been subject to several such claims and may be subject to additional claims in the future as we seek to hire qualified personnel, some of whom may work 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. Certain large broker-dealer competitors have withdrawn from the Protocol for Broker Recruiting (“Protocol”), a voluntary agreement among over 1,700 firms that governs, among other things, the client information that financial advisors may take with them when they affiliate with a new firm. The ability to bring such customer data to a new broker-dealer generally means that the financial advisor is better able to move client account balances to his or her new firm. It is possible that other competitors will similarly withdraw from the Protocol. If the broker-dealers from whom we recruit new financial advisors prevent, or significantly limit, the transfer of client data, our recruiting efforts may be adversely affected and we could experience a higher number of claims against us relating to our recruiting efforts.

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, interest rate changes could adversely affect our net interest spread, the difference between the yield we earn on our assets and the interest rate we pay for deposits and other sources of funding, which in turn impacts our net interest income and earnings. Interest rate changes 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 and an increase in fees received on our multi-bank deposit sweep program. 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 loans, deposits, securities, short-term borrowings, long-term debt, trading account assets and liabilities, derivatives and private equity investments. Market

14

conditions that change from time to time, thereby exposing us to market risk, include fluctuations in interest rates, equity prices, foreign 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 our capital requirements, which could have an adverse effect on our business results, financial condition and liquidity. See Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in this Form 10-K for additional information regarding our exposure to and approaches to managing market risk.

We are exposed to credit risk.

We are generally exposed to the risk that third parties that owe us money, securities, or other assets will fail to meet their performance obligations due to numerous causes, including bankruptcy, lack of liquidity, or operational failure, among others. We actively buy and sell securities from and to clients and counterparties in the normal course of our broker-dealers’ market-making and underwriting businesses, which exposes us to credit risk. Although generally collateralized by the underlying security to the transaction, we still face risk associated with changes in the market value of collateral through settlement date. We also hold certain securities, loans and derivatives as part of our trading inventory. Deterioration in the actual or perceived credit quality of the underlying issuers of securities or loans, or the non-performance of issuers and counterparties to certain derivative contracts could result in trading losses.

We borrow securities from, and lend securities to, other broker-dealers, and may also enter into agreements to repurchase and/or resell securities as part of investing and financing activities. A sharp change in the security market values utilized in these transactions may result in losses if counterparties to these transactions fail to honor their commitments.

We manage the risk associated with these transactions by establishing and monitoring credit limits, as well as by monitoring collateral and transaction levels daily. Significant deterioration in the credit quality of one of our counterparties could lead to widespread concerns about the credit quality of other counterparties in the same industry, thereby exacerbating our credit risk exposure.

We permit our clients to purchase securities on margin. During periods of steep declines in securities prices, the value of the collateral securing client margin loans may fall below the amount of the purchaser’s indebtedness. If clients are unable to provide additional collateral for these margin loans, we may incur losses on those margin transactions. This may cause us to incur additional expenses defending or pursuing claims or litigation related to counterparty or client defaults.

We deposit our cash in depository institutions as a means of maintaining the liquidity necessary to meet our operating needs, and we also facilitate the deposit of cash awaiting investment in depository institutions on behalf of our clients. A failure of a depository institution to return these deposits could severely impact our operating liquidity, result in significant reputational damage, and adversely impact our financial performance.

We also incur credit risk by lending to businesses and individuals through the offering of loans, including commercial and industrial loans, commercial and residential mortgage loans, tax-exempt loans, home equity lines of credit, and margin and other loans collateralized by securities. We also incur credit risk through our investments. Our credit risk and credit losses can increase if our loans or investments are concentrated among borrowers or issuers engaged in the same or similar activities, industries, or geographies, or to borrowers or issuers who as a group may be uniquely or disproportionately affected by economic or market conditions. The deterioration of an individually large exposure, for example due to natural disasters, health emergencies or pandemics, acts of terrorism, severe weather events or other adverse economic events, could lead to additional loan loss provisions and/or charges-offs, or credit impairment of our investments, and subsequently have a material impact on our net income and regulatory capital.

Declines in the real estate market or sustained economic downturns may cause us to write down the value of some of the loans in Stifel Bancorp’s portfolio, foreclose on certain real estate properties, or write down the value of some of our securities portfolio. Credit quality generally may also be affected by adverse changes in the financial performance or condition of our debtors or deterioration in the strength of the U.S. economy.

See Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in this Form 10-K for additional information regarding our exposure to and approaches to managing credit risk.

Our business depends on fees earned from the management of client accounts by our primary broker-dealer and asset management subsidiaries.

We have grown our asset management business in recent years, including with the acquisitions of ZCM in 2013, 1919 Investment Counsel in 2014, Barclays in 2015 and Ziegler in 2018, which has increased the risks associated with this business relative to our overall operations. The market environment in recent years has resulted in a shift to passive investment products, which generate lower fees than actively managed products. A continued trend toward passive investments or changes in market values or in the fee structure of asset management accounts would affect our revenues, business and financial condition. Asset management fees often are primarily comprised of base management and incentive fees. Management fees are primarily based on assets under management (“AUM”). AUM balances are impacted by net inflows/outflows of client assets and market values. Below-market investment

15

performance by our funds and portfolio managers could result in a loss of managed accounts and could result in reputational damage that might make it more difficult to attract new investors and thus further impact our business and financial condition. If we were to experience the loss of managed accounts, our fee revenue would decline. In addition, in periods of declining market values, our values of AUM may resultantly decline, which would negatively impact our fee revenues.

Our underwriting, market-making, trading, and other business activities place our capital at risk.

We may incur losses and be subject to reputational harm to the extent that, for any reason, we are unable to sell securities we have underwritten at the anticipated price levels. As an underwriter, we also are subject to heightened standards regarding liability for material misstatements or omissions in prospectuses and other offering documents relating to offerings in which we are involved. As a market-maker, we may own positions in specific securities, and these undiversified holdings concentrate the risk of market fluctuations and may result in greater losses than would be the case if our holdings were more diversified. In addition, despite risk mitigation policies, we may incur losses as a result of positions we hold in connection with our market-making or underwriting activities. While it is not typical, from time to time and as part of our underwriting processes, we may carry significant positions in securities of a single issuer or issuers engaged in a specific industry. Sudden changes in the value of these positions could impact our financial results.

We have made, and to the limited extent permitted by applicable regulations, may continue to make principal investments in private equity funds and other illiquid investments; however, our current focus is on the divestiture of our existing portfolio. We may be unable to realize our investment objectives if we cannot sell or otherwise dispose of our interests at attractive prices or complete a desirable exit strategy. In particular, these risks could arise from changes in the financial condition or prospects of the portfolio companies in which investments are made, changes in economic conditions or changes in laws, regulations, fiscal policies or political conditions. It could take a substantial period of time to identify attractive investment opportunities and then to realize the cash value of such investments. Even if a private equity investment proves to be profitable, it may be several years or longer before any profits can be realized in cash.

The soundness of other financial institutions and intermediaries affects us.

We face the risk of operational failure, termination, or capacity constraints of any of the clearing agents, exchanges, clearing houses, or other financial intermediaries that we use to facilitate our securities transactions. As a result of the consolidation over the years among clearing agents, exchanges, and clearing houses, our exposure to certain financial intermediaries has increased and could affect our ability to find adequate and cost-effective alternatives should the need arise. Any failure, termination, or constraint of these intermediaries could adversely affect our ability to execute transactions, serve our clients, and manage our exposure to risk.

Our ability to engage in routine trading and funding transactions could be adversely affected by the actions and commercial soundness of other financial institutions. Financial services institutions are interrelated as a result of trading, clearing, funding, counterparty, or other relationships. We have exposure to many different industries and counterparties, and we routinely execute transactions with counterparties in the financial industry, including brokers and dealers, commercial banks, investment banks, mutual and hedge funds, and other institutional clients. Defaults by, or even rumors or questions about the financial condition of, one or more financial services institutions, or the financial services industry generally, have historically led to market-wide liquidity problems and could lead to losses or defaults by us or by other institutions. Many of these transactions expose us to credit risk in the event of default of our counterparty or client. In addition, our credit risk may be exacerbated when the collateral held by us cannot be realized or is liquidated at prices not sufficient to recover the full amount of the loan or derivative exposure due us. Losses arising in connection with counterparty defaults may have a material adverse effect on our results of operations.

We continue to experience increased pricing pressures in areas of our business, which may impair our future revenue and profitability.

We continue to experience pricing pressures on trading margins and commissions in fixed income and equity trading. In the fixed income market, regulatory requirements have resulted in greater price transparency, leading to price competition and decreased trading margins. In the equity market, we experience pricing pressure from institutional clients to reduce commissions, partially due to the industry trend toward unbundling fees related to research and execution. Our trading margins have been further compressed by the use of electronic and direct market access trading, which has created additional competitive pressure. We believe that price competition and pricing pressures in these and other areas will continue as institutional investors continue to reduce the amounts they are willing to pay, including by reducing the number of brokerage firms they use, and some of our competitors seek to obtain market share by reducing fees, commissions, or margins.

Growth of our business could increase costs and regulatory and integration risks.

We continue to grow, including through acquisitions and through our recruiting efforts. Integrating acquired businesses, providing a platform for new businesses, and partnering with other firms involve risks and present financial, managerial, and operational challenges. We may incur significant expense in connection with expanding our existing businesses, recruiting financial advisors, or making strategic acquisitions or investments. Our overall profitability would be negatively affected if investments and expenses associated with such growth are not matched or exceeded by the revenues derived from such investments or growth.

16

Expansion may also create a need for additional compliance, documentation, risk management, and internal control procedures, and often involves hiring additional personnel to address these procedures. To the extent such procedures are not adequate or not adhered to with respect to our expanded business or any new business, we could be exposed to a material loss or regulatory sanction.

Moreover, to the extent we pursue acquisitions we may be unable to complete such acquisitions on acceptable terms. We may be unable to integrate any acquired business into our existing business successfully. Difficulties we may encounter in integrating an acquired business could have an adverse effect on our business, financial condition, and results of operations. In addition, we may need to raise capital or borrow funds in order to finance an acquisition, which could result in dilution or increased leverage. We may not be able to obtain financing on favorable terms or perhaps at all.

The growth of our bank subsidiaries may expose us to increased credit risk, operational risk, regulatory risk, and sensitivity to market interest rates along with increased regulation, examinations, and supervision by regulators.

We have experienced growth in the investment portfolio, which includes available-for-sale and held-to-maturity securities, and the loan portfolio of Stifel Bancorp, which is funded by affiliated customer deposits. Although our stock-secured loans are collateralized by assets held in our clients’ brokerage accounts, we are exposed to some credit and operational risk associated with these loans. With the increase in deposits and resulting liquidity, we have been able to expand our investment portfolio. In addition, Stifel Bancorp has significantly grown its mortgage and commercial lending businesses. Although we believe we have conservative underwriting policies in place, there are inherent risks associated with the mortgage banking business.

As a result of the high percentage of our assets and liabilities that are in the form of interest-bearing or interest-related instruments, we are more sensitive to changes in interest rates, in the shape of the yield curve, or in relative spreads between market interest rates.

The monetary, tax, and other policies of the government and its agencies, including the Federal Reserve, have a significant impact on interest rates and overall financial market performance. An important function of the Federal Reserve is to regulate the national supply of bank credit and market interest rates. The actions of the Federal Reserve influence the rates of interest that we charge on loans and that we pay on borrowings and interest-bearing deposits, which may also affect the value of our on-balance sheet and off-balance sheet financial instruments. We cannot predict the nature or timing of future changes in monetary, tax, and other policies or the effect that they may have on our activities and results of operations.

In addition, our bank subsidiaries are heavily regulated at the state and federal level. This regulation is to protect depositors, federal deposit insurance funds, consumers, and the banking system as a whole, but not our shareholders. Federal and state regulations can significantly restrict our businesses, and we are subject to various regulatory actions, which could include fines, penalties, or other sanctions for violations of laws and regulatory rules if we are ultimately found to be out of compliance.

We face intense competition.

We are engaged in intensely competitive businesses. We compete on the basis of a number of factors, including the quality of our financial advisors and associates, our products and services, pricing (such as execution pricing and fee levels), location, and reputation in relevant markets. Over time, there has been substantial consolidation and convergence among companies in the financial services industry, which has significantly increased the capital base and geographic reach of our competitors. See the section entitled “Competition” of Item 1 of this Form 10-K for additional information about our competitors.

We compete directly with national full-service broker-dealers, investment banking firms, and commercial banks, and to a lesser extent, with discount brokers and dealers and investment advisors. In addition, we face competition from more recent entrants into the market and increased use of alternative sales channels by other firms. We also compete indirectly for investment assets with insurance companies, real estate firms, hedge funds, and others. This competition could cause our business to suffer.

To remain competitive, our future success also depends, in part, on our ability to develop and enhance our products and services. The inability to develop new products and services, or enhance existing offerings, could have a material adverse effect on our profitability. In addition, the continued development of internet, networking, or telecommunication technologies or other technological changes could require us to incur substantial expenditures to enhance or adapt our services or infrastructure.

We are exposed to operational risk.

Our diverse operations expose us to risk of loss resulting from inadequate or failed internal processes, people, and systems external events, including technological or connectivity failures either at the exchanges in which we do business or between our data centers, operations processing sites, or our branches. Our businesses depend on our ability to process and monitor, on a daily basis, a large number of complex transactions across numerous and diverse markets. The inability of our systems to accommodate an increasing volume of transactions could also constrain our ability to expand our businesses. Our financial, accounting, data processing, or other operating systems and facilities may fail to operate properly or become disabled as a result of events that are wholly or partially beyond our control, adversely affecting our ability to process these transactions or provide these services. Operational risk exists in every activity, function, or unit of our business, and can take the form of internal or external fraud, employment and hiring practices, an error in meeting a professional obligation, or failure to meet corporate fiduciary standards. It is not always possible to deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in all cases. If our employees engage in misconduct, our businesses would be adversely affected. Operational risk also exists in the event of business

17

disruption, system failures, or failed transaction processing. Third parties with which we do business could also be a source of operational risk, including with respect to breakdowns or failures of the systems or misconduct by the employees of such parties. In addition, as we change processes or introduce new products and services, we may not fully appreciate or identify new operational risks that may arise from such changes. Increasing use of automated technology has the potential to amplify risks from manual or system processing errors, including outsourced operations.

Our business contingency plan in place is intended to ensure we have the ability to recover our critical business functions and supporting assets, including staff and technology, in the event of a business interruption. Despite the diligence we have applied to the development and testing of our plans, due to unforeseen factors, our ability to conduct business may, in any case, be adversely affected by a disruption involving physical site access, catastrophic events, including weather-related events, events involving electrical, environmental, or communications malfunctions, as well as events impacting services provided by others that we rely upon which could impact our employees or third parties with whom we conduct business.

See Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in this Form 10-K for additional information regarding our exposure to and approaches to managing operational risk.

A continued interruption to our telecommunications or data processing systems, or the failure to effectively update the technology we utilize, could be materially adverse to our business.

Our businesses rely extensively on data processing and communications systems. In addition to better serving clients, the effective use of technology increases efficiency and enables us to reduce costs. Adapting or developing our technology systems to meet new regulatory requirements, client needs, and competitive demands is critical for our business. Introduction of new technology presents challenges on a regular basis. There are significant technical and financial costs and risks in the development of new or enhanced applications, including the risk that we might be unable to effectively use new technologies or adapt our applications to emerging industry standards.

Our continued success depends, in part, upon our ability to: (i) successfully maintain and upgrade the capability of our technology systems; (ii) address the needs of our clients by using technology to provide products and services that satisfy their demands; and (iii) retain skilled information technology employees. Failure of our technology systems, which could result from events beyond our control, or an inability to effectively upgrade those systems or implement new technology-driven products or services, could result in financial losses, liability to clients, violations of applicable privacy and other applicable laws and regulatory sanctions. See Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Risk Management” of this report for additional information regarding our exposure to and approaches for managing these types of operational risks.

Any cyber-attack or other security breach of our technology systems, or those of our clients or other third-party vendors we rely on, could subject us to significant liability and harm our reputation.

Our operations rely heavily on the secure processing, storage and transmission of sensitive and confidential financial, personal and other information in our computer systems and networks. There have been several highly publicized cases involving financial services companies reporting the unauthorized disclosure of client or other confidential information in recent years, as well as cyber-attacks involving the theft, dissemination and destruction of corporate information or other assets, in some cases as a result of failure to follow procedures by employees or contractors or as a result of actions by third parties. Like other financial services firms, we are regularly the target of attempted cyber-attacks, including unauthorized access, mishandling or misuse of information, computer viruses or malware, denial-of-service attacks, phishing or other forms of social engineering, and other events, and we seek to continuously monitor and develop our systems to protect our technology infrastructure and data from misappropriation or corruption. Cyber-attacks can originate from a variety of sources, including third parties affiliated with foreign governments, organized crime or terrorist organizations. Third parties may also attempt to place individuals within our company or induce employees, clients or other users of our systems to disclose sensitive information or provide access to our data, and these types of risks may be difficult to detect or prevent. Although cybersecurity incidents among financial services firms are on the rise, we have not experienced any material losses relating to cyber-attacks or other information security breaches. However, the techniques used in these attacks are increasingly sophisticated, change frequently and are often not recognized until launched. Although we seek to maintain a robust suite of authentication and layered information security controls, including our cyber threat analytics, data encryption and tokenization technologies, anti-malware defenses and vulnerability management program, any one or combination of these controls could fail to detect, mitigate or remediate these risks in a timely manner. Despite our implementation of protective measures and endeavoring to modify them as circumstances warrant, our computer systems, software and networks may be vulnerable to human error, natural disasters, power loss, spam attacks, unauthorized access, distributed denial of service attacks, computer viruses and other malicious code, and other events that could result in significant liability and damage to our reputation, and have an ongoing impact on the security and stability of our operations.

We also rely on numerous third party service providers to conduct other aspects of our business operations, and we face similar risks relating to them. While we regularly conduct security assessments on these third party vendors, we cannot be certain that their information security protocols are sufficient to withstand a cyber-attack or other security breach. In addition, in order to access our products and services, our customers may use computers and other devices that are beyond our security control systems.

18

Notwithstanding the precautions we take, if a cyber-attack or other information security breach were to occur, this could jeopardize the information we confidentially maintain, or otherwise cause interruptions in our operations or those of our clients and counterparties, exposing us to liability. As attempted attacks continue to evolve in scope and sophistication, we may be required to expend substantial additional resources to modify or enhance our protective measures, to investigate and remediate vulnerabilities or other exposures or to communicate about cyber-attacks to our customers. Though we have insurance against some cyber-risks and attacks, we may be subject to litigation and financial losses that exceed our policy limits or are not covered under any of our current insurance policies. A technological breakdown could also interfere with our ability to comply with financial reporting and other regulatory requirements, exposing us to potential disciplinary action by regulators. Additionally, the SEC issued guidance in February 2018 stating that, as a public company, we are expected to have controls and procedures that relate to cybersecurity disclosure, and are required to disclose information relating to certain cyber-attacks or other information security breaches in disclosures required to be made under the federal securities laws. Further, successful cyber-attacks at other large financial institutions or other market participants, whether or not we are affected, could lead to a general loss of customer confidence in financial institutions that could negatively affect us, including harming the market perception of the effectiveness of our security measures or the financial system in general, which could result in reduced use of our financial products and services.

Further, in light of the high volume of transactions we process, the large number of our clients, partners and counterparties, and the increasing sophistication of malicious actors, a cyber-attack could occur and persist for an extended period of time without detection. We expect that any investigation of a cyber-attack would take substantial amounts of time, and that there may be extensive delays before we obtain full and reliable information. During such time we would not necessarily know the extent of the harm or how best to remediate it, and certain errors or actions could be repeated or compounded before they are discovered and remediated, all of which would further increase the costs and consequences of such an attack.

We may also be subject to liability under various data protection laws. In providing services to clients, we manage, utilize and store sensitive or confidential client or employee data, including personal data. As a result, we are subject to numerous laws and regulations designed to protect this information, such as U.S. federal, state and international laws governing the protection of personally identifiable information. These laws and regulations are increasing in complexity and number. If any person, including any of our associates, negligently disregards or intentionally breaches our established controls with respect to client or employee data, or otherwise mismanages or misappropriates such data, we could be subject to significant monetary damages, regulatory enforcement actions, fines and/or criminal prosecution. In addition, unauthorized disclosure of sensitive or confidential client or employee data, whether through system failure, employee negligence, fraud or misappropriation, could damage our reputation and cause us to lose clients and related revenue. Potential liability in the event of a security breach of client data could be significant. Depending on the circumstances giving rise to the breach, this liability may not be subject to a contractual limit or an exclusion of consequential or indirect damages.

See Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in this Form 10-K for additional information regarding our exposure to and approaches to managing these types of operational risk.

We are exposed to risks of legal proceedings, which may result in significant losses to us that we cannot recover. Claimants in these proceedings may be customers, employees, or regulatory agencies, among others, seeking damages for mistakes, errors, negligence, or acts of fraud by our employees.

Many aspects of our business involve substantial risks of liability, arising in the normal course of business. Participants in the financial services industry face an increasing amount of litigation and arbitration proceedings. Dissatisfied clients regularly make claims against broker-dealers and their employees for, among others, negligence, fraud, unauthorized trading, suitability, churning, failure to supervise, breach of fiduciary duty, employee errors, intentional misconduct, unauthorized transactions by financial advisors or traders, improper recruiting activity, and failures in the processing of securities transactions. The risks associated with potential litigation often may be difficult to assess or quantify, and the existence and magnitude of potential claims often remain unknown for substantial periods of time.

These types of claims expose us to the risk of significant loss. Acts of fraud are difficult to detect and deter, and while we believe our supervisory procedures are reasonably designed to detect and prevent violations of applicable laws, rules, and regulations, we cannot assure investors that our risk management procedures and controls will prevent losses from fraudulent activity. In our role as underwriter and selling agent, we may be liable if there are material misstatements or omissions of material information in prospectuses and other communications regarding underwritten offerings of securities. At any point in time, the aggregate amount of existing claims against us could be material. While we do not expect the outcome of any existing claims against us to have a material adverse impact on our business, financial condition, or results of operations, we cannot assure you that these types of proceedings will not materially and adversely affect our company. We do not carry insurance that would cover payments regarding these liabilities, except for insurance against certain fraudulent acts of our employees. In addition, our bylaws provide for the indemnification of our officers, directors, and employees to the maximum extent permitted under Delaware law. In the future, we may be the subject of indemnification assertions under these documents by our officers, directors, or employees who have or may become defendants in litigation. These claims for indemnification may subject us to substantial risks of potential liability.

19

During challenging market conditions, the volume of claims and amount of damages sought in litigation and regulatory proceedings against financial institutions has historically increased. Litigation risks include potential liability under securities laws or other laws for alleged materially false or misleading statements made in connection with securities offerings and other transactions, issues related to the suitability of our investment advice based on our clients’ investment objectives (including auction rate securities), the inability to sell or redeem securities in a timely manner during adverse market conditions, contractual issues, employment claims, and potential liability for other advice we provide to participants in strategic transactions. Substantial legal liability could have a material adverse financial impact or cause us significant reputational harm, which, in turn, could seriously harm our business and future business prospects.

In addition to the foregoing financial costs and risks associated with potential liability, the costs of defending individual litigation and claims continue to increase over time. The amount of outside attorneys’ fees incurred in connection with the defense of litigation and claims could be substantial and might materially and adversely affect our results of operations.

See Item 3, “Legal Proceedings,” in this Form 10-K for a discussion of our legal matters and Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in this Form 10-K for a discussion regarding our approach to managing legal risk.

The preparation of the consolidated financial statements requires the use of estimates that may vary from actual results, and new accounting standards could adversely affect future reported results.

The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Such estimates and assumptions may require management to make difficult, subjective, and complex judgments about matters that are inherently uncertain.

Our financial instruments, including certain trading assets and liabilities, available-for-sale securities, investments, including certain loans, intangible assets, and private equity investments, among other items, require management to make a determination of their fair value in order to prepare our consolidated financial statements. Where quoted market prices are not available, we may make fair value determinations based on internally developed models or other means, which ultimately rely to some degree on our subjective judgment. Some of these instruments and other assets and liabilities may have no directly observable inputs, making their valuation particularly subjective, and consequently, based on significant estimation and judgment. In addition, sudden illiquidity in markets or declines in prices of certain securities may make it more difficult to value certain items, which may lead to the possibility that such valuations will be subject to further change or adjustment, as well as declines in our earnings in subsequent periods.

Our accounting policies and methods are fundamental to how we record and report our financial condition and results of operations. The Financial Accounting Standards Board and the SEC have at times revised the financial accounting and reporting standards that govern the preparation of our financial statements. In addition, accounting standard setters and those who interpret the accounting standards may change or even reverse their previous interpretations or positions on how these standards should be applied. These changes can be hard to predict and can materially impact how we record and report our financial condition and results of operations. In some cases, we could be required to apply a new or revised standard retroactively, resulting in our restating prior period financial statements. For a further discussion of some of our significant accounting policies and standards, see the “Critical Accounting Estimates” discussion within Item 7, and Note 2 of the Notes to Consolidated Financial Statements, in this Form 10-K.

Our risk management and conflict of interest policies and procedures may leave us exposed to unidentified or unanticipated risk.

We seek to manage, monitor and control our market, credit, operational, legal, and regulatory risk through operational and compliance reporting systems, internal controls, management review processes, and other mechanisms; however, there can be no assurance that our procedures will be effective. While we use limits and other risk mitigation techniques, those techniques and the judgments that accompany their application cannot anticipate unforeseen economic and financial outcomes or the specifics and timing of such outcomes. Our risk management methods may not predict future risk exposures effectively. In addition, some of our risk management methods are based on an evaluation of information regarding markets, clients and other matters that are based on assumptions that may no longer be accurate or may have limited predictive value. A failure to manage our growth adequately, including growth in the products or services we offer, or to manage our risk effectively, could materially and adversely affect our business and financial condition.

Financial services firms are subject to numerous actual or perceived conflicts of interest, which are under growing scrutiny by U.S. federal and state regulators and SROs such as FINRA. Our risk management processes include addressing potential conflicts of interest that arise in our business. Management of potential conflicts of interest has become increasingly complex as we expand our business activities. A perceived or actual failure to address conflicts of interest adequately could affect our reputation, the willingness of clients to transact business with us or give rise to litigation or regulatory actions. Therefore, there can be no assurance that conflicts of interest will not arise in the future that could cause result in material harm to our business and financial condition.

For more information on how we monitor and manage market and certain other risks, see Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in this Form 10-K.

We are exposed to risks from international markets.

We do business in other parts of the world and, as a result, are exposed to risks, including economic, market, litigation and regulatory risks. Our businesses and revenues derived from non-U.S. operations are subject to risk of loss from currency fluctuations, social or political instability, less established regulatory regimes, changes in governmental or central bank policies, downgrades in the credit ratings of sovereign countries, expropriation, nationalization, confiscation of assets and unfavorable legislative, economic and political developments. Action or inaction in any of these operations, including failure to follow proper practices with respect to regulatory compliance and/or corporate governance, could harm our operations and our reputation. We also invest or trade in the securities of corporations located in non-U.S. jurisdictions. Revenues from trading non-U.S. securities also may be subject to negative fluctuations as a result of the above-mentioned factors.

Employee misconduct, which is difficult to detect and deter, could harm us by impairing our ability to attract and retain clients and subject us to significant legal liability and reputational harm.

There is a risk that our employees could engage in misconduct that adversely affects our business. For example, our banking business often requires that we deal with confidential matters of great significance to our clients. If our associates were to improperly use or disclose confidential information provided by our clients, we could be subject to regulatory sanctions and suffer serious harm to our reputation, financial position, current client relationships and ability to attract future clients. We are also subject to a number of obligations and standards arising from our asset management business and our authority over the assets managed by our asset management business. In addition, our financial advisors may act in a fiduciary capacity, providing financial planning, investment advice, and discretionary asset management. The violation of these obligations and standards by any of our associates would adversely affect our clients and us. It is not always possible to deter associate misconduct, and the precautions we take to detect and prevent this activity may not be effective. If our associates engage in misconduct, our business would be adversely affected.

A significant decline in our domestic client cash balances could negatively impact our net revenues and/or our ability to fund Stifel Bancorp’s growth.

We rely heavily on bank deposits as a low-cost source of funding for Stifel Bancorp to extend loans to clients and purchase investment securities. Our bank deposits are primarily driven by our multi-bank sweep program in which clients’ cash deposits in their brokerage accounts are swept into FDIC-insured interest-bearing accounts at our bank subsidiaries and various third-party banks. A significant reduction in our domestic clients’ cash balances, a change in the allocation of that cash between our bank subsidiaries and third-party banks, or a transfer of cash away from our company, could impact our net revenues and our ability to fund our bank subsidiaries’ growth.

RISKS RELATED TO OUR REGULATORY ENVIRONMENT

Financial services firms have been subject to regulatory changes resulting from the Dodd-Frank Act and increased regulatory scrutiny over the last several years, increasing the risk of financial liability and reputational harm resulting from adverse regulatory actions.

Financial services firms over the last several years have been operating in an onerous regulatory environment. The industry has experienced increased scrutiny from various regulators, including the SEC, the Federal Reserve, the OCC and the CFPB, in addition to stock exchanges, FINRA and state attorneys general. Penalties and fines imposed by regulatory authorities have increased substantially in recent years. We may be adversely affected by changes in the interpretation or enforcement of existing laws, rules and regulations.

The Dodd-Frank Act enacted sweeping changes and an unprecedented increase in the supervision and regulation of the financial services industry (see Item 1, “Regulation,” of this report for a discussion of such changes). The ultimate impact that the Dodd-Frank Act and implementing regulations, as further modified by the Economic Growth Regulatory Relief, and Consumer Protection Act and other financial services legislation, will have on us and the financial services industry more broadly cannot be quantified until all of the implementing regulations called for under the legislation have been finalized and fully implemented. Nevertheless, it is apparent that these legislative and regulatory changes could affect our revenue, limit our ability to pursue business opportunities, impact the value of our assets, require us to alter at least some of our business practices, impose additional compliance costs, and otherwise adversely affect our businesses.

The Dodd-Frank Act impacts the manner in which we market our products and services, manage our business and operations, and interact with regulators, all of which could materially impact our results of operations, financial condition and liquidity. Certain provisions of the Dodd-Frank Act that have impacted or may impact our businesses include: the establishment of a uniform fiduciary standard or a best interest standard for broker-dealers; regulatory oversight of incentive compensation; the imposition of increased capital requirements on financial holding companies; prohibition of proprietary trading; restrictions on investments in covered funds; and, to a lesser extent, greater oversight over derivatives trading. There is also increased regulatory scrutiny (and related compliance costs) as we continue to grow and surpass certain consolidated asset thresholds established under the Dodd-Frank Act, which have the effect of imposing enhanced standards and requirements on larger institutions. These include, but are not limited to, our bank subsidiaries’ oversight by the CFPB. The CFPB has had an active enforcement agenda and any action taken by the CFPB could result in requirements to alter or cease offering affected products and services, make such products and services less attractive, impose

21

additional compliance measures, or result in fines, penalties or required remediation. To the extent the Dodd-Frank Act impacts the operations, financial condition, liquidity and capital requirements of unaffiliated financial institutions with whom we transact business, those institutions may seek to pass on increased costs, reduce their capacity to transact, or otherwise present inefficiencies in their interactions with us. We are also required to comply with the Volcker Rule’s provisions. Although we have not historically engaged in significant levels of proprietary trading, due to our underwriting and market-making activities and our investments in covered funds, we have experienced and expect to continue to experience increased operational and compliance costs and changes to our private equity investments. Any changes to regulations or changes to the supervisory approach may also result in increased compliance costs to the extent we are required to modify our existing compliance policies, procedures and practices.

Broker-dealers and investment advisors are subject to regulations covering all aspects of the securities business, including, but not limited to: sales and trading methods; trade practices among broker-dealers; use and safekeeping of clients’ funds and securities; capital structure of securities firms; anti-money laundering efforts; recordkeeping; and the conduct of directors, officers and employees. Any violation of these laws or regulations could subject us to the following events, any of which could have a material adverse effect on our business, financial condition and prospects: civil and criminal liability; sanctions, which could include the revocation of our subsidiaries’ registrations as investment advisors or broker-dealers; the revocation of the licenses of our financial advisors; censures; fines; or a temporary suspension or permanent bar from conducting business.

Regulatory actions brought against us may result in judgments, settlements, fines, penalties or other results, any of which could have a material adverse effect on our business, financial condition or results of operations. There is no assurance that regulators will be satisfied with the policies and procedures implemented by our company and its subsidiaries. In addition, from time to time, the Company and its affiliates may become subject to additional findings with respect to supervisory, compliance or other regulatory deficiencies, which could subject us to additional liability, including penalties, and restrictions on our business activities. Among other things, these restrictions could limit our ability to make investments, complete acquisitions, expand into new business lines, pay dividends and/or engage in share repurchases. See Item 1, “Regulation,” of this report for additional information regarding our regulatory environment and Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Risk Management,” in this report regarding our approaches to managing regulatory risk.

The Basel III regulatory capital standards impose additional capital and other requirements on us that could decrease our profitability.

In July 2013, the Federal Reserve, the OCC, and the FDIC released final U.S. Basel III Rules, which implemented the global regulatory capital reforms of Basel III and certain changes required by the Dodd-Frank Act. The U.S. Basel III Rules increase the quantity and quality of regulatory capital, establish a capital conservation buffer, and make selected changes to the calculation of risk-weighted assets. We became subject to requirements under the final U.S. Basel III Rules as of January 1, 2015, subject to a phase-in period for several of its provisions, including the new minimum capital ratio requirements, the capital conservation buffer, and the regulatory capital adjustments and deductions. The increased capital requirements stipulated under the U.S. Basel III Rules could restrict our ability to grow during favorable market conditions or require us to raise additional capital. As a result, our business, results of operations, financial condition, and prospects could be adversely affected.

Failure to comply with regulatory capital requirements primarily applicable to our company, our bank subsidiaries, or our broker-dealer subsidiaries would significantly harm our business.

Our company and it bank subsidiaries are subject to various regulatory and capital requirements administered by various federal regulators in the U.S. and  accordingly, must meet specific capital guidelines that involve quantitative measures of our company and our bank subsidiaries assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classifications for both our company and its bank subsidiaries are also subject to qualitative judgments by U.S. federal regulators based on components of our capital, risk weightings of assets, off-balance sheet transactions, and other factors. Quantitative measures established by regulation to ensure capital adequacy require our company and its bank subsidiaries to maintain minimum amounts and ratios of Common Equity Tier 1, Tier 1, and Total capital to risk-weighted assets, Tier 1 capital to average assets, and capital conservation buffers (as defined in the regulations). Failure to meet minimum capital requirements can trigger certain mandatory (and potentially additional discretionary) actions by regulators that, if undertaken, could harm either our company or our bank subsidiaries’ operations and financial condition.

We are subject to the SEC’s uniform net capital rule (Rule 15c3-1) and FINRA’s net capital rule, which may limit our ability to make withdrawals of capital from our broker-dealer subsidiaries. The uniform net capital rule sets the minimum level of net capital that a broker-dealer must maintain and also requires that a portion of its assets be relatively liquid. FINRA may prohibit a member firm from expanding its business or paying cash dividends if resulting net capital falls below certain thresholds. Regulatory capital requirements applicable to some of our significant subsidiaries may impede access to funds our company needs to make payments on any such obligations.

See Note 19 of the Notes to Consolidated Financial Statements of this Form 10-K for further information on regulations and capital requirements.

22

Changes in requirements relating to the standard of conduct for broker-dealers applicable under state law may adversely affect our businesses.

In April 2016, the DOL issued its final rule defining the term “fiduciary” and related exemptions in the context of ERISA and retirement accounts. On June 21, 2018, the U.S. Court of Appeals for the Fifth Circuit Court issued an order vacating the DOL Rule and related exemptions. We dedicated significant resources to interpret and implement policies to comply with the DOL Rule and continue to evaluate the solutions available to retirement accounts, with additional changes possible. While the overall impact of the recently vacated DOL Rule may have ultimately been adverse to our financial condition, results of operations and liquidity, we may benefit from the changes to systems, processes, and offerings completed for the DOL Rule in complying with forthcoming regulatory initiatives.

In April 2018, the SEC proposed Regulation Best Interest, which would require a broker-dealer to act in the best interest of a retail customer when making a recommendation of any securities transaction or investment strategy involving securities to such customer. We anticipate that if a rule imposing heightened standards on broker-dealers is adopted by the SEC or fiduciary rules are adopted at the state level, we will be required to incur costs in order to review and possibly modify the compliance plan and approach that we had previously implemented for the now-vacated DOL Rule. Implementation of any rules addressing similar matters may negatively impact our results including the impact of increased costs related to compliance, legal and information technology.

Numerous regulatory changes and enhanced regulatory and enforcement activity relating to the asset management business may increase our compliance and legal costs and otherwise adversely affect our business.

The SEC has proposed certain measures that would establish a new framework to replace the requirements of Rule 12b-1 under the 1940 Act with respect to how mutual funds pay fees to cover the costs of selling and marketing their shares. The staff of the SEC’s Office of Compliance, Inspections and Examinations has indicated that it is reviewing the use of fund assets to pay for fees to sub-transfer agents and sub-administrators for services that may be deemed to be distribution-related. Any adoption of such measures would be phased in over a number of years. As these measures are neither final nor undergoing implementation throughout the financial services industry, their impact cannot be fully ascertained at this time. As this regulatory trend continues, it could adversely affect our operations and, in turn, our financial results.

Asset management businesses have experienced a number of highly publicized regulatory inquiries, which have resulted in increased scrutiny within the industry and new rules and regulations for mutual funds, investment advisors and broker-dealers. As some of our wholly owned subsidiaries are registered as investment advisors with the SEC, increased regulatory scrutiny and rulemaking initiatives may result in additional operational and compliance costs or the assessment of significant fines or penalties against our asset management business, and may otherwise limit our ability to engage in certain activities. It is not possible to determine the extent of the impact of any new laws, regulations or initiatives that have been or may be proposed, or whether any of the proposals will become law. Conformance with any new laws or regulations could make compliance more difficult and expensive and affect the manner in which we conduct business, including our product and service offerings.

In addition, U.S. and foreign governments have taken regulatory actions impacting the investment management industry, and may continue to do so including expanding current (or enacting new) standards, requirements and rules that may be applicable to us and our subsidiaries. For example, several states and municipalities in the U.S. have adopted “pay-to-play” rules, which could limit our ability to charge advisory fees. Such “pay-to-play” rules could affect the profitability of that portion of our business.

The use of “soft dollars,” where a portion of commissions paid to broker-dealers in connection with the execution of trades also pays for research and other services provided to advisors, is periodically reexamined and may be limited or modified in the future. A substantial portion of the research relied on by our investment management business in the investment decision-making process is generated internally by our investment analysts and external research, including external research paid for with soft dollars. This external research is generally used for information gathering or verification purposes, and includes broker-provided research, as well as third-party provided databases and research services. If the use of soft dollars is limited, we may have to bear some of these additional costs.

New regulations regarding the management of hedge funds and the use of certain investment products, including additional recordkeeping and disclosure requirements, may impact our asset management business and result in increased costs.

As a financial holding company, our company’s liquidity depends on payments from its subsidiaries, which may be subject to regulatory restrictions.

We are a financial holding company and therefore depend on dividends, distributions, and other payments from our subsidiaries in order to meet our obligations, including debt service obligations. Our subsidiaries are subject to laws and regulations that restrict dividend payments or authorize regulatory bodies to prevent or reduce the flow of funds from those subsidiaries to our company. Our broker-dealers and bank subsidiaries are limited in their ability to lend or transact with affiliates and are subject to minimum regulatory capital and other requirements, as well as limitations on their ability to use funds deposited with them in broker or bank accounts to fund their businesses. These requirements may hinder our company’s ability to access funds from its subsidiaries. We may also become subject to a prohibition or limitations on our ability to pay dividends or repurchase our common stock. The federal banking regulators, including the OCC, the Federal Reserve, and the FDIC, as well as the SEC (through FINRA) have the authority

23

and under certain circumstances, the obligation, to limit or prohibit dividend payments and stock repurchases by the banking organizations they supervise, including our company and its bank subsidiaries. See Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources” of this report for additional information on liquidity and how we manage our liquidity risk.

RISKS RELATED TO OUR COMMON STOCK

The market price of our common stock may continue to be volatile.

The market price of our common stock has been, and is likely to continue to be, volatile and subject to fluctuations. Stocks of financial institutions have, from time to time, experienced significant downward pressure in connection with economic conditions or events and may again experience such pressures in the future. Changes in the stock market generally or as it concerns our industry, as well as geopolitical, economic, and business factors unrelated to us, may also affect our stock price. Significant declines in the market price of our common stock or failure of the market price to increase could harm our ability to recruit and retain key employees, including those who have joined us from companies we have acquired, reduce our access to debt or equity capital, and otherwise harm our business or financial condition. In addition, we may not be able to use our common stock effectively as consideration in connection with future acquisitions.

Our current shareholders may experience dilution in their holdings if we issue additional shares of common stock as a result of future offerings or acquisitions where we use our common stock.

As part of our business strategy, we may seek opportunities for growth through strategic acquisitions in which we may consider issuing equity securities as part of the consideration. Additionally, we may obtain additional capital through the public sale of debt or equity securities. If we sell equity securities, the value of our common stock could experience dilution. Furthermore, these securities could have rights, preferences, and privileges more favorable than those of the common stock. Moreover, if we issue additional shares of common stock in connection with equity compensation, future acquisitions, or as a result of financing, an investor’s ownership interest in our company will be diluted.

The issuance of any additional shares of common stock or securities convertible into or exchangeable for common stock or that represent the right to receive common stock, or the exercise of such securities, could be substantially dilutive to holders of our common stock. Holders of our shares of common stock have no preemptive rights that entitle holders to purchase their pro rata share of any offering of shares of any class or series, and therefore, such sales or offerings could result in increased dilution to our shareholders. The market price of our common stock could decline as a result of sales or issuance of shares of our common stock or securities convertible into or exchangeable for common stock.

Provisions in our certificate of incorporation and bylaws and of Delaware law may prevent or delay an acquisition of our company, which could decrease the market value of our common stock.

Our articles of incorporation and bylaws and Delaware law contain provisions that are intended to deter abusive takeover tactics by making them unacceptably expensive to prospective acquirers and to encourage prospective acquirers to negotiate with our board of directors rather than to attempt a hostile takeover. Delaware law also imposes some restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock. We believe these provisions protect our shareholders from coercive or otherwise unfair takeover tactics by requiring potential acquirers to negotiate with our board of directors and by providing our board of directors with more time to assess any acquisition proposal. These provisions are not intended to make our company immune from takeovers. However, these provisions apply even if the offer may be considered beneficial by some shareholders and could delay or prevent an acquisition that our board of directors determines is not in the best interests of our company and our shareholders.

ITEM 2. PROPERTIES

The following table sets forth the location, approximate square footage, and use of each of the principal properties used by our company during the year ended December 31, 2018. We own our executive offices in St. Louis, Missouri. We lease or sublease a majority of these properties under operating leases. Such leases expire at various times through 2029. 

Location	Approximate Square Footage		Use
St. Louis, Missouri		434,000	Headquarters and administrative offices of Stifel,    Global Wealth Management operations (including CSA),    and Institutional Group operations
New York, New York		355,500	Global Wealth Management and Institutional Group operations
Baltimore, Maryland		97,500	Institutional Group operations and Administrative offices
San Francisco, California		88,500	Global Wealth Management and Institutional Group operations
Florham Park, New Jersey		74,000	Global Wealth Management and Institutional Group operations
Chicago, Illinois		62,500	Global Wealth Management and Institutional Group operations
Birmingham, Alabama		62,500	Global Wealth Management and Institutional Group operations

We also maintain operations in 404 leased offices in various locations throughout the United States and in certain foreign countries, primarily for our broker-dealer business. We lease 369 private client offices. In addition, Stifel Bancorp leases one location for its administrative offices and operations. Our Institutional Group segment leases 35 offices in the United States and certain foreign locations. We believe that, at the present time, the space available to us in the facilities under our current leases and co-location arrangements are suitable and adequate to meet our needs and that such facilities have sufficient productive capacity and are appropriately utilized.

Leases for the branch offices of our independent contractor firms are the responsibility of the respective independent financial advisors.

See Note 17 of the Notes to Consolidated Financial Statements for further information regarding our lease obligations.

ITEM 3. LEGAL PROCEEDINGS

Our company and its subsidiaries are named in and subject to various proceedings and claims arising primarily from our securities business activities, including lawsuits, arbitration claims, class actions, and regulatory matters. Some of these claims seek substantial compensatory, punitive, or indeterminate damages. Our company and its subsidiaries are also involved in other reviews, investigations, and proceedings by governmental and self-regulatory organizations regarding our business, which may result in adverse judgments, settlements, fines, penalties, injunctions, and other relief. We are contesting allegations in these claims, and we believe that there are meritorious defenses in each of these lawsuits, arbitrations, and regulatory investigations. In view of the number and diversity of claims against our company, the number of jurisdictions in which litigation is pending, and the inherent difficulty of predicting the outcome of litigation and other claims, we cannot state with certainty what the eventual outcome of pending litigation or other claims will be.

We have established reserves for potential losses that are probable and reasonably estimable that may result from pending and potential legal actions, investigations, and regulatory proceedings. In many cases, however, it is inherently difficult to determine whether any loss is probable or reasonably possible or to estimate the amount or range of any potential loss, particularly where proceedings may be in relatively early stages or where plaintiffs are seeking substantial or indeterminate damages. Matters frequently need to be more developed before a loss or range of loss can reasonably be estimated.

In our opinion, based on currently available information, review with outside legal counsel, and consideration of amounts provided for in our consolidated financial statements with respect to these matters the ultimate resolution of these matters will not have a material adverse impact on our financial position and results of operations. However, resolution of one or more of these matters may have a material effect on the results of operations in any future period, depending upon the ultimate resolution of those matters and depending upon the level of income for such period. For matters where a reserve has not been established and for which we believe a loss is reasonably possible, as well as for matters where a reserve has been recorded but for which an exposure to loss in excess of the amount accrued is reasonably possible, based on currently available information, we believe that such losses will not have a material effect on our consolidated financial statements.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of the financial condition and results of operations of our company should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in this Annual Report on Form 10-K for the year ended December 31, 2018.

Unless otherwise indicated, the terms “we,” “us,” “our,” or “our company” in this report refer to Stifel Financial Corp. and its wholly owned subsidiaries.

Executive Summary

We operate as a financial services and bank holding company. We have built a diversified business serving private clients, institutional investors, and investment banking clients located across the country. Our principal activities are: (i) private client services, including securities transaction and financial planning services; (ii) institutional equity and fixed income sales, trading, and research, and municipal finance; (iii) investment banking services, including mergers and acquisitions, public offerings, and private placements; and (iv) retail and commercial banking, including personal and commercial lending programs.

Our core philosophy is based upon a tradition of trust, understanding, and studied advice. We attract and retain experienced professionals by fostering a culture of entrepreneurial, long-term thinking. We provide our private, institutional, and corporate clients quality, personalized service, with the theory that if we place clients’ needs first, both our clients and our company will prosper. Our unwavering client and employee focus have earned us a reputation as one of the nation’s leading wealth management and investment banking firms. We have grown our business both organically and through opportunistic acquisitions.

We plan to maintain our focus on revenue growth with a continued appreciation for the development of quality client relationships. Within our private client business, our efforts will be focused on recruiting experienced financial advisors with established client relationships. Within our capital markets business, our focus continues to be on providing quality client management and product diversification. In executing our growth strategy, we will continue to seek out opportunities that allow us to take advantage of the consolidation among middle-market firms, whereby allowing us to increase market share in our private client and institutional group businesses.

Stifel Financial Corp., through its wholly owned subsidiaries, is principally engaged in retail brokerage; securities trading; investment banking; investment advisory; retail, consumer, and commercial banking; and related financial services. Our major geographic area of concentration is throughout the United States, with a growing presence in the United Kingdom and Europe. Our principal customers are individual investors, corporations, municipalities, and institutions.

Our ability to attract and retain highly skilled and productive employees is critical to the success of our business. Accordingly, compensation and benefits comprise the largest component of our expenses, and our performance is dependent upon our ability to attract, develop, and retain highly skilled employees who are motivated and committed to providing the highest quality of service and guidance to our clients.

On March 19, 2018, the Company completed the acquisition of Ziegler, a privately held investment bank, capital markets and proprietary investments firm that has 55 private client advisors in five states that manage approximately $5 billion in client assets. Ziegler provides its clients with capital raising, strategic advisory services, equity and fixed income sales & trading and research. The acquisition was funded with cash from operations.

On August 31, 2018, the Company completed the acquisition of BBI and its wholly owned subsidiary, The Business Bank of St. Louis, a full-service banking facility with approximately $600.0 million in assets that operates from a single location. Upon the closing of the transaction, the Business Bank of St. Louis was renamed “Stifel Bank” and Business Bancshares, Inc. was renamed “Stifel Bancorp, Inc.” Stifel Bancorp is the holding company for Stifel Bank & Trust, and its wholly owned subsidiaries, and Stifel Bank. Under the terms of the merger agreement, each outstanding share of BBI common stock (except for shares of BBI common stock held by BBI as treasury stock) were converted into the right to receive 0.705 shares of our company’s common stock, with fractional shares settled with cash. We issued approximately 2.0 million shares for acquisition of BBI.

On October 1, 2018, the Company completed the acquisition of Rand, an independent investment adviser that provides comprehensive wealth management and investment counsel services to individuals, families, and institutions. The acquisition was funded with cash from operations.

Results for the year ended December 31, 2018

For the year ended December 31, 2018, net revenues increased 3.4% to a record $3.0 billion compared to $2.9 billion during the comparable period in 2017. This represents our 23^rd consecutive year of record net revenues. Net income available to common shareholders for the year ended December 31, 2018 increased 121.7% to $384.6 million, or $4.73 per diluted common share, compared to $173.5 million, or $2.14 per diluted common share, in 2017. For the year ended December 31, 2018, our Global Wealth Management segment posted record net revenues and pre-tax income.

Our revenue growth for the year ended December 31, 2018 was primarily attributable to the growth in asset management and service fees as a result of increased assets under management; higher net interest income as a result of an increase in interest-earning assets at Stifel Bancorp and an increase in advisory fees; partially offset by a decrease in brokerage revenues and capital raising revenues.

External Factors Impacting Our Business

Performance in the financial services industry in which we operate is highly correlated to the overall strength of economic conditions and financial market activity. Overall market conditions are a product of many factors, which are beyond our control and mostly unpredictable. These factors may affect the financial decisions made by investors, including their level of participation in the financial markets. In turn, these decisions may affect our business results. With respect to financial market activity, our profitability is sensitive to a variety of factors, including the demand for investment banking services as reflected by the number and size of equity and debt financings and merger and acquisition transactions, the volatility of the equity and fixed income markets, the level and shape of various yield curves, the volume and value of trading in securities, and the value of our customers’ assets under management. The municipal underwriting market is challenging as state and local governments reduce their debt levels. Investors are showing a lack of demand for longer-dated municipals and are reluctant to take on credit or liquidity risks.

Our overall financial results continue to be highly and directly correlated to the direction and activity levels of the United States equity and fixed income markets. At December 31, 2018, the key indicators of the markets’ performance, the NASDAQ, the S&P 500, and Dow Jones Industrial Average closed 3.9%, 6.2%, and 5.6% lower than their December 31, 2017, closing prices, respectively.

As a participant in the financial services industry, we are subject to complicated and extensive regulation of our business. The recent economic and political environment has led to legislative and regulatory initiatives, both enacted and proposed, that could substantially intensify the regulation of the financial services industry and may significantly impact us.

Year Ended December 31, 2018, Compared With Year Ended December 31, 2017

For the year ended December 31, 2018, net revenues increased 3.4% to a record $3.0 billion from $2.9 billion in 2017. This represents our 23^rd consecutive year of record net revenues.  The primary factors impacting the growth in revenues were increases in our fee-based accounts and the continued growth of our balance sheet that contributed to higher net interest income. The growth in our revenue was negatively impacted by the challenging environment for our brokerage business.

32

Commissions – Commission revenues are primarily generated from agency transactions in OTC and listed equity securities, insurance products, and options. In addition, commission revenues also include distribution fees for promoting and distributing mutual funds.

For the year ended December 31, 2018, commission revenues decreased 3.1% to $657.7 million from $678.9 million in 2017. The decrease is primarily attributable to a decrease in trading volumes.

Principal transactions – Principal transaction revenues are gains and losses on secondary trading, principally fixed income brokerage revenues.

For the year ended December 31, 2018, principal transactions revenues decreased 11.5% to $351.4 million from $396.8 million in 2017. The decrease is primarily attributable to lower institutional fixed income brokerage revenues, as the industry continues to face systematic issues, including the impact of passive investing and the increase in electronic trading.

Investment banking – Investment banking revenues include: (i) capital-raising revenues representing fees earned from the underwriting of debt and equity securities, and (ii) advisory fees related to corporate debt and equity offerings, municipal debt offerings, merger and acquisitions, private placements, and other investment banking advisory fees.

For the year ended December 31, 2018, investment banking revenues decreased 2.6%, to $707.7 million from $726.8 million in 2017. The decrease is primarily attributable to a decrease in fixed income capital raising revenues, partially offset by an increase in equity capital raising revenues and advisory fees. Investment banking revenues were positively impacted by the adoption of the new revenue recognition standard in 2018 that requires gross presentation of certain costs that were previously offset against investment banking revenues.

Capital-raising revenues decreased 8.2% to $336.2 million for the year ended December 31, 2018, from $366.1 million in 2017. For the year ended December 31, 2018, equity capital-raising revenues increased 11.4% to $226.5 million from $203.4 million in 2017. For the year ended December 31, 2018, fixed income capital-raising revenues decreased 32.6% to $109.7 million from $162.7 million in 2017.

Advisory fees increased 3.0% to $371.5 million for the year ended December 31, 2018, from $360.6 million in 2017. The increase is primarily attributable to an increase in the number of completed advisory transactions during 2018, including growth in our fund placement business.

Asset management and service fees – Asset management and service fees include fees for asset-based financial services provided to individuals and institutional clients. Investment advisory fees are charged based on the value of assets in fee-based accounts. Asset management and service fees are affected by changes in the balances of client assets due to market fluctuations and levels of net new client assets.

For the year ended December 31, 2018, asset management and service fee revenues increased 14.8% to a record $806.2 million from $702.1 million in 2017. The increase is primarily a result of an increase in the number and value of fee-based accounts, an increase in fees earned on client cash balances, and an increase of interest rates on fees earned on client cash. See “Asset management and service fees” in the Global Wealth Management segment discussion for information on the changes in asset management and service fees revenues.

Other income – For the year ended December 31, 2018, other income decreased 31.9% to $25.6 million from $37.5 million during 2017. The decrease is primarily attributable to an increase in investment losses.

Year Ended December 31, 2017, Compared With Year Ended December 31, 2016

For the year ended December 31, 2017, net revenues increased 13.6% to $2.9 billion from $2.6 billion in 2016. The primary factors impacting the growth in revenues were the strength of the investment banking franchise, the growth of our balance sheet that contributed to higher net interest income, and the increase in our fee-based accounts. The growth in our revenue was negatively impacted by the challenging environment for our brokerage business.

Commissions – For the year ended December 31, 2017, commission revenues decreased 7.0% to $678.9 million from $730.0 million in 2016. The decrease is primarily attributable to lower volumes caused by the shift to fee-based accounts as a result of the Department of Labor’s fiduciary rule, lower volumes, and lower volatility experienced by our Institutional Group.

Principal transactions – For the year ended December 31, 2017, principal transactions revenues decreased 16.5% to $396.8 million from $475.4 million in 2016. The decrease is primarily attributable to a decline in trading volumes, low interest rates, a flattening yield curve, and low volatility.

Investment banking – For the year ended December 31, 2017, investment banking revenues increased 41.7%, to $726.8 million from $513.0 million in 2016. The increase is primarily attributable to an increase in capital raising revenues and advisory fees.

Capital-raising revenues increased 42.8% to $366.1 million for the year ended December 31, 2017, from $256.4 million in 2016. For the year ended December 31, 2017, equity capital-raising revenues increased 41.2% to $203.4 million from $144.1 million in 2016. For the year ended December 31, 2017, fixed income capital-raising revenues increased 44.9% to $162.7 million from $112.3 million in 2016.

33

Advisory fees increased 40.5% to $360.6 million for the year ended December 31, 2017, from $256.6 million in 2016. The increase is primarily attributable to an increase in the number of completed advisory transactions during 2017, as well as contributions made from Eaton fund placement franchise.

Asset management and service fees – For the year ended December 31, 2017, asset management and service fee revenues increased 20.5% to $702.1 million from $582.8 million in 2016. The increase is primarily a result of an increase in the number and value of fee-based accounts. See “Asset management and service fees” in the Global Wealth Management segment discussion for information on the changes in asset management and service fees revenues.

Other income – For the year ended December 31, 2017, other income decreased 19.8% to $37.5 million from $46.8 million in 2016. The decrease is primarily a result of a decrease in loan origination fees, and lower investment gains.

Year Ended December 31, 2018, Compared With Year Ended December 31, 2017

Net interest income – Net interest income is the difference between interest earned on interest-earning assets and interest paid on funding sources. Net interest income is affected by changes in the volume and mix of these assets and liabilities, as well as by fluctuations in interest rates and portfolio management strategies. For the year ended December 31, 2018, net interest income increased 23.9% to a record $476.4 million from $384.4 million in 2017.

For the year ended December 31, 2018, interest revenue increased 42.3% to $646.4 million from $454.4 million in 2017, principally as a result of a $160.0 million increase in interest revenue generated from the growth in interest-earning assets of Stifel Bancorp and higher margin interest income. The average interest-earning assets of Stifel Bancorp increased to $15.8 billion during the year ended December 31, 2018, compared to $13.6 billion during 2017 at average interest rates of 3.52% and 2.93%, respectively.

For the year ended December 31, 2018, interest expense increased 142.9% to $170.1 million from $70.0 million in 2017. The increase is primarily attributable to an increase in interest-bearing liabilities at Stifel Bancorp (deposits and FHLB advances) and the issuance of 5.20% senior notes in October 2017.

Year Ended December 31, 2017, Compared With Year Ended December 31, 2016

Net interest income – For the year ended December 31, 2017, net interest income increased 69.0% to $384.4 million from $227.5 million in 2016.

35

For the year ended December 31, 2017, interest revenue increased 54.4% to $454.4 million from $294.3 million in 2016, principally as a result of a $157.8 million increase in interest revenue generated from the growth in interest-earning assets of Stifel Bancorp. The average interest-earning assets of Stifel Bancorp increased to $13.6 billion during the year ended December 31, 2017, compared to $9.6 billion in 2016 at average interest rates of 2.93% and 2.50%, respectively.

For the year ended December 31, 2017, interest expense increased 4.7% to $70.0 million from $66.9 million in 2016. The increase in interest expense is primarily attributable to an increase in interest expense paid on the interest-bearing liabilities of Stifel Bancorp.

Year Ended December 31, 2018, Compared With Year Ended December 31, 2017

Except as noted in the following discussion of variances, the underlying reasons for the increase in non-interest expenses can be attributed principally to our continued expansion, both organically and through our acquisitions, and increased administrative overhead to support the growth in our segments.

Compensation and benefits – Compensation and benefits expenses, which are the largest component of our expenses, include salaries, bonuses, transition pay, benefits, amortization of stock-based compensation, employment taxes, and other employee-related costs. A significant portion of compensation expense is comprised of production-based variable compensation, including discretionary bonuses, which fluctuates in proportion to the level of business activity, increasing with higher revenues and operating profits. Other compensation costs, including base salaries, stock-based compensation amortization, and benefits, are more fixed in nature.

For the year ended December 31, 2018, compensation and benefits expense decreased 9.6% to $1.8 billion from $2.0 billion in 2017. Compensation and benefits expense as a percentage of net revenues was 58.5% for the year ended December 31, 2018, compared to 66.9% for the year ended December 31, 2017. The decrease is primarily attributable to growth of our higher margin businesses and a decrease in deferred compensation expense from prior year. In the fourth quarter of 2017, in response to US Tax Reform, we accelerated the vesting of certain outstanding debenture awards and modified certain outstanding restricted stock units.

Occupancy and equipment rental – For the year ended December 31, 2018, occupancy and equipment rental expense decreased 0.1% to $222.4 million from $222.7 million in 2017.

Communications and office supplies – Communications expense includes costs for telecommunication and data transmission, primarily for obtaining third-party market data information. For the year ended December 31, 2018, communications and office supplies expense increased 5.1% to $140.3 million from $133.5 million in 2017. The increase is primarily attributable to an increase in communication and quote and office supplies.

Commissions and floor brokerage – For the year ended December 31, 2018, commissions and floor brokerage expense decreased 4.9% to $42.0 million from $44.1 million in 2017. The decrease is primarily attributable to a decrease in trading volumes.

Other operating expenses – Other operating expenses primarily include license and registration fees, litigation-related expenses, which consist of amounts we reserve and/or payout for legal and regulatory matters, travel and entertainment, promotional, and professional service expenses.

For the year ended December 31, 2018, other operating expenses increased 5.9% to $315.2 million from $297.6 million in 2017. The increase is primarily attributable to the adoption of the new revenue recognition standard that requires gross presentation of certain costs that were previously offset against revenue that added $33.8 million to other operating expenses; and an increase in professional fees, travel costs, subscriptions, and advertising expense, partially offset by a decrease in legal expense, FDIC insurance, and provision for loan losses

Provision for income taxes – For the year ended December 31, 2018, our provision for income taxes was $140.4 million, representing an effective tax rate of 26.3%, compared to $86.7 million in 2017, representing an effective tax rate of 32.2%.

36

The provision for income taxes for the year ended December 31, 2018 was primarily impacted by the tax reform enacted in the fourth quarter of 2017 that, among other things, lowered the federal corporate income tax rate from 35% to 21%.

Year Ended December 31, 2017, Compared With Year Ended December 31, 2016

Except as noted in the following discussion of variances, the underlying reasons for the increase in non-interest expenses can be attributed principally to our continued expansion, both organically and through our acquisitions, and increased administrative overhead to support the growth in our segments.

Compensation and benefits – For the year ended December 31, 2017, compensation and benefits expense increased 13.5% to $2.0 billion from $1.7 billion in 2016. The increase is principally due to the following: 1) increased variable compensation as a result of increased revenue production, 2) an increase in fixed compensation for additional administrative support staff, and 3) an increase in deferred compensation expense as a result of the acceleration of the vesting of certain outstanding debenture awards and the modification of certain outstanding restricted stock units. These, and other actions described below, were taken by the Company in response to the Tax Cuts and Jobs Act (“Tax Legislation”) that was enacted in the fourth quarter of 2017 to maximize tax savings.

Compensation and benefits expense as a percentage of net revenues was 66.9% for the year ended December 31, 2017, compared to 67.0% for the year ended December 31, 2016.

Occupancy and equipment rental – For the year ended December 31, 2017, occupancy and equipment rental expense decreased 3.7% to $222.7 million from $231.3 million in 2016. The decrease is primarily due to lower equipment costs and rent expense.

Communications and office supplies – For the year ended December 31, 2017, communications and office supplies expense decreased 4.4% to $133.5 million from $139.6 million in 2016. The decrease is primarily attributable to a decrease in quote equipment, telecommunication costs, and office supplies as a result of cost saving initiatives.

Commissions and floor brokerage – For the year ended December 31, 2017, commissions and floor brokerage expense decreased 0.4% to $44.1 million from $44.3 million in 2016. The decrease is primarily attributable to a decrease in trading volumes.

Other operating expenses – For the year ended December 31, 2017, other operating expenses increased 2.1% to $297.6 million from $291.6 million in 2016. The increase is primarily attributable to an increase in the provision for loan losses, FDIC insurance expense, and license expense, offset partially by a decrease in legal, travel, and professional service expense.  

Provision for income taxes – For the year ended December 31, 2017, our provision for income taxes was $86.7 million, representing an effective tax rate of 32.2%, compared to $61.1 million in 2016, representing an effective tax rate of 42.8%.

The provision for income taxes for the year ended December 31, 2017 was primarily impacted by 1) actions taken by the Company in response to the Tax Legislation that was enacted in the fourth quarter of 2017 to maximize tax savings; 2) the favorable impact of the adoption of new accounting guidance during 2017 associated with stock-based compensation; and 3) the revaluation of the Company’s deferred tax assets as a result of the enacted Tax Legislation.

SEGMENT PERFORMANCE FROM CONTINUING OPERATIONS

Our reportable segments include Global Wealth Management, Institutional Group, and Other.

Our Global Wealth Management segment consists of two businesses, the Private Client Group and Stifel Bancorp. The Private Client Group includes branch offices and independent contractor offices of our broker-dealer subsidiaries located throughout the United States. These branches provide securities brokerage services, including the sale of equities, mutual funds, fixed income products, and insurance, as well as offering banking products to their private clients through our bank subsidiaries, which provide residential, consumer, and commercial lending, as well as FDIC-insured deposit accounts to customers of our broker-dealer subsidiaries and to the general public.

The success of our Global Wealth Management segment is dependent upon the quality of our products, services, financial advisors, and support personnel, including our ability to attract, retain, and motivate a sufficient number of these associates. We face competition for qualified associates from major financial services companies, including other brokerage firms, insurance companies, banking institutions, and discount brokerage firms. Segment revenue growth, operating income, and segment pre-tax operating margin are used to evaluate and measure segment performance by our management team in deciding how to allocate resources and in assessing performance.

The Institutional Group segment includes institutional sales and trading. It provides securities brokerage, trading, and research services to institutions with an emphasis on the sale of equity and fixed income products. This segment also includes the management of and participation in underwritings for both corporate and public finance (exclusive of sales credits generated through the Private Client Group, which are included in the Global Wealth Management segment), merger and acquisition, and financial advisory services.

The success of our Institutional Group segment is dependent upon the quality of our personnel, the quality and selection of our investment products and services, pricing (such as execution pricing and fee levels), and reputation. Segment operating income and segment pre-tax operating margin are used to evaluate and measure segment performance by our management team in deciding how to allocate resources and in assessing performance.

The Other segment includes interest income from stock borrow activities, unallocated interest expense, interest income and gains and losses from investments held, amortization of stock-based awards, compensation expense associated with the expensing of restricted stock awards with no continuing service requirements in conjunction with recent acquisitions and the actions taken by the Company in response to the Tax Regulation enacted in the fourth quarter of 2017, and all unallocated overhead cost associated with the execution of orders; processing of securities transactions; custody of client securities; receipt, identification, and delivery of funds and securities; compliance with regulatory and legal requirements; internal financial accounting and controls; and general administration and acquisition charges.

NET REVENUES

For the year ended December 31, 2018, Global Wealth Management net revenues increased 9.2% to a record $2.0 billion from $1.8 billion in 2017. The increase in net revenues for the year ended December 31, 2018, over 2017, is primarily attributable to the growth in asset management and service fees; an increase in net interest income, as a result of the growth of interest-earning assets at Stifel Bancorp; partially offset by a decrease in brokerage revenues and investment banking.

Commissions – For the year ended December 31, 2018, commission revenues decreased 0.5% to $472.1 million from $474.6 million in 2017.

Principal transactions – For the year ended December 31, 2018, principal transactions revenues decreased 11.1% to $166.0 million from $186.7 million in 2017.

Brokerage revenues – For the year ended December 31, 2018, brokerage revenues decreased 3.5% to $638.2 million from $661.3 million in the comparable period in 2017. Brokerage revenues were impacted by the continued migration of client activity from brokerage to asset management activities.

Asset management and service fees – For the year ended December 31, 2018, asset management and service fees increased 14.9% to $806.1 million from $701.8 million in 2017.

The value of assets in fee-based accounts at December 31, 2018, increased 3.0% to $90.2 billion from $87.6 billion at December 31, 2017.

Interest revenue – For the year ended December 31, 2018, interest revenue increased 38.3% to $614.7 million from $444.5 million in 2017.

See “Net Interest Income – Stifel Bancorp” below for a further discussion of the changes in net interest income.

Investment banking – Investment banking, which represents sales credits for investment banking underwritings, decreased 22.5% to $31.4 million for the year ended December 31, 2018, from $40.5 million in 2017. The decrease is primarily attributable to a decrease in corporate debt and equity sales credits as compared to 2017.

Other income – For the year ended December 31, 2018, other income decreased 37.2% to $11.5 million from $18.2 million in 2017. The decrease is primarily attributable to an increase in investment losses compared to 2017.

Interest expense – For the year ended December 31, 2018, interest expense increased 153.0% to $111.5 million from $44.1 million in 2017.

Compensation and benefits – For the year ended December 31, 2018, compensation and benefits expense increased 6.2% to $968.1 million from $912.0 million in 2017. The increase is principally due to increased variable compensation as a result of increased production.

Occupancy and equipment rental – For the year ended December 31, 2018, occupancy and equipment rental expense increased 3.2% to $105.2 million from $101.9 million in 2017. The increase is primarily attributable an increase in locations in 2018.

Communications and office supplies – For the year ended December 31, 2018, communications and office supplies expense increased 6.1% to $62.2 million from $58.7 million in 2017. The increase is primarily attributable to higher communication expenses associated with the growth of the business.

Other operating expenses – For the year ended December 31, 2018, other operating expenses decreased 3.5% to $99.0 million from $102.6 million in 2017. The decrease in other operating expenses is primarily attributable to a decrease in the provision for loan losses and insurance expense, partially offset by higher advertising costs, travel expenses, and professional fees.

INCOME BEFORE INCOME TAXES

40

For the year ended December 31, 2018, income before income taxes increased 17.6% to $737.0 million from $626.9 million in 2017.  Profit margins (income before income taxes as a percent of net revenues) have increased to 37.0% for the year ended December 31, 2018 from 34.4% in 2017. The improvement in profit margin from 2017 is a result of an increase in revenues, as well as our focus on expense management.

Year Ended December 31, 2017, Compared With Year Ended December 31, 2016

NET REVENUES

For the year ended December 31, 2017, Global Wealth Management net revenues increased 16.6% to $1.8 billion from $1.6 billion in 2016. The increase in net revenues for the year ended December 31, 2017, over 2016, is primarily attributable to an increase in net interest revenues, as a result of the growth of interest-earning assets at Stifel Bancorp; the growth in asset management and service fees; and an increase in principal transaction revenues. The increase in net revenues was partially offset by a decrease in commission revenues, investment banking revenues, and other income. Net revenues were also negatively impacted by the sale of the Sterne Agee independent contractor business during the third quarter of 2016.

Commissions – For the year ended December 31, 2017, commission revenues decreased 3.4% to $474.6 million from $491.2 million in 2016. The decrease is primarily attributable to a decrease in agency transactions in insurance products, OTC and listed equity securities, and mutual funds as a result of lower trading volumes impacting the environment for both us and the industry, as clients are migrating their assets to fee-based accounts.

Principal transactions – For the year ended December 31, 2017, principal transactions revenues increased 4.1% to $186.7 million from $179.4 million in 2016. The increase is primarily attributable to an increase in corporate debt products as a result of higher trading volumes and the current interest rate environment. The increase is partially offset by a decrease in corporate equity and municipal debt products and a decrease in trading profits from 2016.

Asset management and service fees – For the year ended December 31, 2017, asset management and service fees increased 20.6% to $701.8 million from $581.9 million in 2016. The increase is primarily a result of an increase in assets under management in our fee-based accounts, and, to a lesser extent, from the increase in fed fund rates that benefit our client cash deposits held at third-part banks. Fee-based account revenues are primarily billed based on values as of the prior period end.

The value of assets in fee-based accounts at December 31, 2017, increased 24.7% to $87.6 billion from $70.2 billion at December 31, 2016.

Interestrevenue– For the year ended December 31, 2017, interest revenue increased 59.0% to $444.5 million from $279.6 million in 2016. The increase is primarily due to the growth of the interest-earning assets of Stifel Bancorp. See “Net Interest Income – Stifel Bancorp” below for a further discussion of the changes in net interest income.

Investment banking – Investment banking decreased 4.1% to $40.5 million for the year ended December 31, 2017, from $42.2 million in 2016. The decrease is primarily attributable to a decrease in corporate debt sales credits as compared to 2016. The decrease is partially offset by an increase in corporate equity sales credits from 2016.

Other income – For the year ended December 31, 2017, other income decreased 8.5% to $18.2 million from $19.9 million in 2016. The decrease is primarily attributable to a decline in mortgage fee revenues from loan originations.

Interest expense – For the year ended December 31, 2017, interest expense increased 42.9% to $44.1 million from $30.8 million in 2016. The increase is primarily attributable to higher interest expense on the interest-bearing liabilities of Stifel Bancorp. See “Net Interest Income – Stifel Bancorp” below for a further discussion of the changes in net interest income.

NON-INTEREST EXPENSES

For the year ended December 31, 2017, Global Wealth Management non-interest expenses increased 5.5% to $1.2 billion from $1.1 billion in 2016.

Compensation and benefits – For the year ended December 31, 2017, compensation and benefits expense increased 4.8% to $912.0 million from $870.6 million in 2016. The increase is principally due to increased variable compensation as a result of increased production. Compensation and benefits expense as a percentage of net revenues was 50.0% for the year ended December 31, 2017, compared to 55.7% in 2016. The compensation and benefits ratio for the year ended December 31, 2017 was positively impacted by the sale of the Sterne Agee independent contractor business during the third quarter of 2016, which had a different pay structure than our legacy private client business.

Occupancy and equipment rental – For the year ended December 31, 2017, occupancy and equipment rental expense increased 4.4% to $101.9 million from $97.6 million in 2016. The increase is primarily attributable to higher occupancy costs and an increase in maintenance expense, partially offset by a decrease in data processing expenses.

Communications and office supplies – For the year ended December 31, 2017, communications and office supplies expense increased 6.0% to $58.7 million from $55.3 million in 2016. The increase is primarily attributable to higher communication and quote equipment, partially offset by a decline in telecommunications expenses.

41

Commissions and floor brokerage – For the year ended December 31, 2017, commissions and floor brokerage expense increased 4.2% to $20.2 million from $19.3 million in 2016.

Other operating expenses – For the year ended December 31, 2017, other operating expenses increased 13.8% to $102.6 million from $90.2 million in 2016. The increase in other operating expenses is primarily attributable to an increase in the provision for loan losses and FDIC insurance, partially offset by a decrease in travel costs.

INCOME BEFORE INCOME TAXES

For the year ended December 31, 2017, income before income taxes increased 45.7% to $626.9 million from $430.3 million in 2016. Profit margins (income before income taxes as a percent of net revenues) have increased to 34.4% for the year ended December 31, 2017 from 27.5% in 2016. The improvement in profit margin from 2016 is a result of an increase in revenues, as well as our focus on expense management.

Net interest income – Net interest income is the difference between interest earned on interest-earning assets and interest paid on funding sources. Net interest income is affected by changes in the volume and mix of these assets and liabilities, as well as by fluctuations in interest rates and portfolio management strategies.

For the year ended December 31, 2018, interest revenue for Stifel Bancorp of $557.8 million was generated from weighted-average interest-earning assets of $15.8 billion at a weighted-average interest rate of 3.52%. For the year ended December 31, 2017, interest revenue for Stifel Bancorp of $397.8 million was generated from weighted-average interest-earning assets of $13.6 billion at a weighted-average interest rate of 2.93%. For the year ended December 31, 2016, interest revenue for Stifel Bancorp of $239.9 million was generated from weighted-average interest-earning assets of $9.6 billion at a weighted-average interest rate of 2.50%. Interest-earning assets principally consist of residential, consumer, and commercial loans, securities, and federal funds sold.

44

Interest expense represents interest on customer money market accounts, time deposits, FHLB advances, and other borrowings. The average balance of interest-bearing liabilities at Stifel Bancorp during the year ended December 31, 2018, was $14.8 billion at a weighted-average interest rate of 0.67%. The average balance of interest-bearing liabilities at Stifel Bancorp during the year ended December 31, 2017, was $12.9 billion at a weighted-average interest rate of 0.17%. The average balance of interest-bearing liabilities at Stifel Bancorp during the year ended December 31, 2016, was $9.2 billion at a weighted-average interest rate of 0.16%.

The growth in Stifel Bancorp has been primarily funded by the growth in deposits associated with brokerage customers of Stifel and, to a lesser extent, with FHLB advances. At December 31, 2018, the balance of Stifel brokerage customer deposits at Stifel Bancorp was $15.2 billion compared to $13.4 billion at December 31, 2017.

Increases and decreases in interest revenue and interest expense result from changes in average balances (volume) of interest-earning bank assets and liabilities, as well as changes in average interest rates. The effect of changes in volume is determined by multiplying the change in volume by the previous year’s average yield/cost. Similarly, the effect of rate changes is calculated by multiplying the change in average yield/cost by the previous year’s volume. Changes applicable to both volume and rate have been allocated proportionately.

Other-Than-Temporary Impairment

We evaluate all securities in an unrealized loss position quarterly to assess whether the impairment is other-than-temporary. Our other-than-temporary impairment (“OTTI”) assessment is a subjective process requiring the use of judgments and assumptions. Accordingly, we consider a number of qualitative and quantitative criteria in our assessment, including the extent and duration of the impairment; recent events specific to the issuer and/or industry to which the issuer belongs; the payment structure of the security; external credit ratings and the failure of the issuer to make scheduled interest or principal payments; the value of underlying collateral; current market conditions; and our company’s ability and intent to hold the investment until its value recovers or the securities mature.

If we determine that impairment on our debt securities is other-than-temporary and we have made the decision to sell the security or it is more likely than not that we will be required to sell the security prior to recovery of its amortized cost basis, we recognize the entire portion of the impairment in earnings. If we have not made a decision to sell the security and we do not expect that we will be required to sell the security prior to recovery of the amortized cost basis, we recognize only the credit component of OTTI in earnings. The remaining unrealized loss due to factors other than credit, or the non-credit component, is recorded in accumulated other comprehensive loss. We determine the credit component based on the difference between the security’s amortized cost basis and the present value of its expected future cash flows, discounted based on the purchase yield. The non-credit component represents the difference between the security’s fair value and the present value of expected future cash flows. Based on the evaluation, we did not recognize any credit-related OTTI during the years ended December 31, 2018, 2017, and 2016, respectively.

We estimate the portion of loss attributable to credit using a discounted cash flow model. Key assumptions used in estimating the expected cash flows include default rates, loss severity, and prepayment rates. Assumptions used can vary widely based on the collateral underlying the securities and are influenced by factors such as collateral type, loan interest rate, geographical location of the borrower, and borrower characteristics.

We believe the gross unrealized losses of $157.9 million related to our investment portfolio, as of December 31, 2018, are attributable to changes in market interest rates. We, therefore, do not expect to incur any credit losses related to these securities. In addition, we have no intent to sell these securities with unrealized losses, and it is not more likely than not that we will be required to sell these securities prior to recovery of the amortized cost. Accordingly, we have concluded that the impairment on these securities is not other-than-temporary.

A loan is determined to be impaired usually when principal or interest becomes 90 days past due or when collection becomes uncertain. At the time a loan is determined to be impaired, the accrual of interest and amortization of deferred loan origination fees is discontinued (“non-accrual status”) and any accrued and unpaid interest income is reversed. At December 31, 2018, we had $24.4 million of impaired loans, net of discounts, which included $9.1 million in troubled debt restructurings. At December 31, 2017, 2016, 2015, and 2014, we had $29.2 million, $26.9 million, $0.9 million, and $4.9 million of impaired loans, respectively, which included $9.1 million, $9.7 million, $0.2 million, and $1.0 million of trouble debt restructurings, respectively. The specific allowance on impaired loans at December 31, 2018, 2017, 2016, 2015, and 2014 was $8.7 million, $9.1 million, $3.4 million, $0.2 million, and $0.3 million, respectively.

The gross interest income related to impaired loans, which would have been recorded had these loans been current in accordance with their original terms, and the interest income recognized on these loans during the years ended December 31, 2018, 2017, 2016, 2015, and 2014, were insignificant to the consolidated financial statements.

Other operating expenses – For the year ended December 31, 2018, other operating expenses increased 33.8% to $126.5 million from $94.6 million in 2017. The increase is primarily due to the previously disclosed adoption of the new revenue recognition standard that added approximately $33.8 million to other operating expenses and an increase in travel costs and professional fees.

For the year ended December 31, 2017, income before income taxes for the Institutional Group segment increased 32.8% to $218.0 million from $164.1 million in 2016. Profit margins (income before income taxes as a percentage of net revenues) have increased to 19.6% for the year ended December 31, 2017, from 16.2% in 2016. The improvement in profit margin from 2016 is a result of an increase in revenues, as well as our focus on expense management.

Analysis of Financial Condition

Our company’s consolidated statements of financial condition consist primarily of cash and cash equivalents, receivables, trading inventory, bank loans, investments, goodwill, loans and advances to financial advisors, bank deposits, and payables. Total assets of $24.5 billion at December 31, 2018, were up 14.7% over December 31, 2017. The increase is primarily attributable to increases in bank loans as a result of our continued focus to grow the balance sheet at Stifel Bancorp and an increase in cash and cash equivalents. Our broker-dealer subsidiary’s gross assets and liabilities, including trading inventory, stock loan/borrow, receivables and payables from/to brokers, dealers, and clearing organizations and clients, fluctuate with our business levels and overall market conditions.

As of December 31, 2018, our liabilities were comprised primarily of deposits of $15.9 billion at Stifel Bancorp, senior notes of $1.0 billion, payables to customers of $837.4 million at our broker-dealer subsidiaries, Federal Home Loan Bank advances of $540.0 million, accrued employee compensation of $460.3 million, as well as accounts payable and accrued expenses of $344.2 million, and

55

borrowings of $180.7 million. To meet our obligations to clients and operating needs, we had $1.9 billion in cash and cash equivalents at December 31, 2018. We also had client brokerage receivables of $1.2 billion at Stifel and $8.5 billion in loans at Stifel Bancorp.

Cash Flow

Cash and cash equivalents increased $1.2 billion to $1.9 billion at December 31, 2018, from $696.3 million at December 31, 2017. Operating activities provided cash of $529.5 million primarily due to net income recognized in 2018 adjusted for non-cash activities and an increase in operating liabilities, offset by an increase in operating assets. Investing activities used cash of $989.2 million due to the growth of our investment portfolio, growth of the loan portfolio, fixed asset purchases, and business acquisitions, partially offset by proceeds from the sale and maturity of securities in our investment portfolio and the sale of investments. Financing activities provided cash of $1.7 billion primarily due to an increase in bank deposits, securities sold under agreements to repurchase, and securities loaned, partially offset by repayments of our short-term borrowings and FHLB advances, share repurchases, and dividends paid on our common and preferred stock. In addition, new accounting guidance associated with stock-based compensation requires cash payments to taxing authorities when withholding shares from an employee's award for tax-withholding purposes to be classified as a financing activity on the consolidated statement of cash flows.

Liquidity and Capital Resources

The Company’s senior management establishes the liquidity and capital policies of our company. The Company’s senior management reviews business performance relative to these policies, monitors the availability of alternative sources of financing, and oversees the liquidity and interest rate sensitivity of our company’s asset and liability position.

Our assets, consisting mainly of cash or assets readily convertible into cash, are our principal source of liquidity. The liquid nature of these assets provides for flexibility in managing and financing the projected operating needs of the business. These assets are financed primarily by our equity capital, corporate debt, debentures to trusts, client credit balances, short-term bank loans, proceeds from securities lending, and other payables. We currently finance our client accounts and firm trading positions through ordinary course borrowings at floating interest rates from various banks on a demand basis, securities lending, and repurchase agreements, with company-owned and client securities pledged as collateral. Changes in securities market volumes, related client borrowing demands, underwriting activity, and levels of securities inventory affect the amount of our financing requirements.

Our bank assets consist principally of available-for-sale and held-to-maturity securities, retained loans, and cash and cash equivalents. Stifel Bancorp’s current liquidity needs are generally met through deposits from brokerage clients and equity capital. We monitor the liquidity of our bank subsidiaries daily to ensure its ability to meet customer deposit withdrawals, maintain reserve requirements, and support asset growth.

As of December 31, 2018, we had $24.5 billion in assets, $11.8 billion of which consisted of cash or assets readily convertible into cash as follows (in thousands, except average days to conversion):

Liquidity Available From Subsidiaries

Liquidity is principally available to our company from Stifel and Stifel Bancorp.

Stifel is required to maintain net capital equal to the greater of $1 million or two percent of aggregate debit items arising from client transactions. Covenants in the Company’s committed financing facilities require the excess net capital of Stifel, our principal broker-dealer subsidiary, to be above a defined amount. At December 31, 2018, Stifel’s excess net capital exceeded the minimum requirement, as defined.  There are also limitations on the amount of dividends that may be declared by a broker-dealer without FINRA approval. See Note 19 of the Notes to Consolidated Financial Statements for more information on the capital restrictions placed on our broker-dealer subsidiaries.

Stifel Bancorp may pay dividends to the parent company without prior approval by its regulator as long as the dividend does not exceed the sum of Stifel Bancorp’s current calendar year and the previous two calendar years’ retained net income and Stifel Bancorp maintains its targeted capital to risk-weighted assets ratios.

Although we have liquidity available to us from our other subsidiaries, the available amounts are not as significant as the amounts described above and, in certain instances, may be subject to regulatory requirements.

Capital Management

We have an ongoing authorization from the Board of Directors to repurchase our common stock in the open market or in negotiated transactions. At December 31, 2018, the maximum number of shares that may yet be purchased under this plan was 9.0 million. We utilize the share repurchase program to manage our equity capital relative to the growth of our business and help to meet obligations under our employee benefit plans.

Liquidity Risk Management

Our businesses are diverse, and our 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. We manage liquidity risk by diversifying our funding sources across products and among individual counterparties within those products.

As a holding company, whereby all of our operations are conducted through our subsidiaries, our cash flow and our ability to service our debt, including the notes, depend upon the earnings of our subsidiaries. Our subsidiaries are separate and distinct legal entities. Our subsidiaries have no obligation to pay any amounts due on the notes or to provide us with funds to pay our obligations, whether by dividends, distributions, loans, or other payments.

Our liquidity requirements may change in the event we need to raise more funds than anticipated to increase inventory positions, support more rapid expansion, develop new or enhanced services and products, acquire technologies, or respond to other unanticipated liquidity requirements. We primarily rely on financing activities and distributions from our subsidiaries for funds to implement our business and growth strategies. Net capital rules, restrictions under our borrowing arrangements of our subsidiaries, as well as the earnings, financial condition, and cash requirements of our subsidiaries, may each limit distributions to us from our subsidiaries.

The availability of outside financing, including access to the capital markets and bank lending, depends on a variety of factors, such as market conditions, the general availability of credit, the volume of trading activities, the overall availability of credit to the financial services sector, and our credit rating. Our cost and availability of funding may be adversely affected by illiquid credit markets and wider credit spreads. As a result of any future concerns about the stability of the markets generally and the strength of counterparties specifically, lenders may from time to time curtail, or even cease to provide, funding to borrowers.

Our liquidity management policies are designed to mitigate the potential risk that we may be unable to access adequate financing to service our financial obligations without material business impact. The principal elements of our liquidity management framework are: (a) daily monitoring of our liquidity needs at the holding company and significant subsidiary level, (b) stress testing the liquidity positions of Stifel and our bank subsidiaries, and (c) diversification of our funding sources.

Monitoring of liquidity – Senior management establishes our liquidity and capital policies. These policies include senior management’s review of short- and long-term cash flow forecasts, review of monthly capital expenditures, the monitoring of the availability of alternative sources of financing, and the daily monitoring of liquidity in our significant subsidiaries. Our decisions on the allocation of capital to our business units consider, among other factors, projected profitability and cash flow, risk, and impact on future liquidity needs. Our treasury department assists in evaluating, monitoring, and controlling the impact that our business activities have on our financial condition, liquidity, and capital structure, as well as maintains our relationships with various lenders. The objectives of these policies are to support the successful execution of our business strategies while ensuring ongoing and sufficient liquidity.

Liquidity stress testing (Firmwide) – A liquidity stress test model is maintained by the Company that measures liquidity outflows across multiple scenarios at the major operating subsidiaries and details the corresponding impact to our holding company and the overall consolidated firm. Liquidity stress tests are utilized to ensure that current exposures are consistent with the Company’s

57

established liquidity risk tolerance and, more specifically, to identify and quantify sources of potential liquidity strain. Further, the stress tests are utilized to analyze possible impacts on the Company’s cash flows, liquidity position, profitability, and solvency. The outflows are modeled over a 30-day liquidity stress timeframe and include the impact of idiosyncratic and macro-economic stress events.

The assumptions utilized in the Company’s liquidity stress tests include, but are not limited to, the following:

• No government support

• No access to equity and unsecured debt markets within the stress horizon

• Higher haircuts and significantly lower availability of secured funding

• Additional collateral required by trading counter-parties, certain exchanges, and clearing organizations related to credit rating downgrades

• Additional collateral required due to collateral substitution, collateral disputes, and uncalled collateral

• Drawdowns on unfunded commitments provided to third parties

• Client cash withdrawals and reduction in customer short positions that fund long positions

At December 31, 2018, the Company maintained sufficient liquidity to meet current and contingent funding obligations as modeled in its liquidity stress test model.

Liquidity stress testing (Stifel Bancorp) – Our bank subsidiaries perform three primary stress tests on its liquidity position. These stress tests are based on the following company-specific stresses: (1) the amount of deposit run-off that they could withstand over a one-month period of time based on its on-balance sheet liquidity and available credit, (2) the ability to fund operations if all available credit were to be drawn immediately, with no additional available credit, and (3) the ability to fund operations under a regulatory prompt corrective action. The goal of these stress tests is to determine their ability to fund continuing operations under significant pressures on both assets and liabilities.

Under all stress tests, our bank subsidiaries consider cash and highly liquid investments as available to meet liquidity needs. In its analysis, our bank subsidiaries consider agency mortgage-backed securities, corporate bonds, and commercial mortgage-backed securities as highly liquid. In addition to being able to be readily financed at modest haircut levels, our bank subsidiaries estimate that each of the individual securities within each of the asset classes described 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. At December 31, 2018, available cash and highly liquid investments comprised approximately 22% of Stifel Bancorp’s assets, which was well in excess of its internal target.

In addition to these stress tests, management performs a daily liquidity review. The daily analysis provides management with all major fluctuations in liquidity. The analysis also tracks the proportion of deposits that Stifel Bancorp is sweeping from its affiliated broker-dealer, Stifel. On a monthly basis, liquidity key performance indicators and compliance with liquidity policy limits are reported to the Board of Directors. Our banking subsidiaries have not violated any internal liquidity policy limits.

Funding Sources

The Company pursues a strategy of diversification of secured and unsecured funding sources (by product and by investor) and attempts to ensure that the tenor of the Company’s liabilities equals or exceeds the expected holding period of the assets being financed. The Company funds its balance sheet through diverse sources. These sources may include the Company’s equity capital, long-term debt, repurchase agreements, securities lending, deposits, committed and uncommitted credit facilities, FHLB advances, and federal funds agreements.

Cash and Cash Equivalents – We held $1.9 billion of cash and cash equivalents at December 31, 2018, compared to $696.3 million at December 31, 2017. Cash and cash equivalents provide immediate sources of funds to meet our liquidity needs.

Securities Available-for-Sale – We held $3.1 billion in available-for-sale investment securities at December 31, 2018, compared to $3.8 billion at December 31, 2017. As of December 31, 2018, the weighted-average life of the investment securities portfolio was approximately 1.5 years. These investment securities provide increased liquidity and flexibility to support our company’s funding requirements.

We monitor our investment portfolio for other-than-temporary impairment based on a number of criteria, including the size of the unrealized loss position, the duration for which the security has been in a loss position, credit rating, the nature of the investments, and current market conditions. For debt securities, we also consider any intent to sell the security and the likelihood we will be required to sell the security before its anticipated recovery. We continually monitor the ratings of our security holdings and conduct regular reviews of our credit-sensitive assets.

58

Deposits – Deposits have become our largest funding source. Deposits provide a stable, low-cost source of funds that we utilize to fund asset growth and to diversify funding sources. We have continued to expand our deposit-gathering efforts through our existing private client network and through expansion. These channels offer a broad set of deposit products that include demand deposits, money market deposits, and certificates of deposit (“CDs”).

As of December 31, 2018, we had $15.9 billion in deposits compared to $13.4 billion at December 31, 2017. The growth in deposits is primarily attributable to the increase in certificates of deposit held by the bank. Our core deposits are comprised of non-interest-bearing deposits, money market deposit accounts, savings accounts, and CDs.

Short-term borrowings – Our short-term financing is generally obtained through short-term bank line financing on an uncommitted, secured basis and securities lending arrangements. We borrow from various banks on a demand basis with company-owned and customer securities pledged as collateral. The value of customer-owned securities used as collateral is not reflected in the consolidated statements of financial condition. We also have an unsecured, committed bank line available.

Our uncommitted secured lines of credit at December 31, 2018, totaled $1.0 billion with six banks and are dependent on having appropriate collateral, as determined by the bank agreements, to secure an advance under the line. The availability of our uncommitted lines is subject to approval by the individual banks each time an advance is requested and may be denied. Our peak daily borrowing on our uncommitted secured lines was $391.0 million during the year ended December 31, 2018. There are no compensating balance requirements under these arrangements. Any borrowings on secured lines of credit are day-to-day and are generally utilized to finance certain fixed income securities. At December 31, 2018, our uncommitted secured lines of credit of $56.0 million were collateralized by company-owned securities valued at $63.0 million.

The Federal Home Loan advances of $540.0 million as of December 31, 2018, are floating-rate advances. The weighted average interest rates during the year ended December 31, 2018, on these advances is 1.61%. The advances are secured by Stifel Bancorp’s residential mortgage loan portfolio and investment portfolio. The interest rates reset on a daily basis. Stifel Bancorp has the option to prepay these advances without penalty on the interest reset date.

Unsecured short-term borrowings – On April 26, 2017, we amended our existing Credit Agreement, whereby increasing our revolving credit facility to $200.0 million. The credit facility expires in March 2020. The applicable interest rate under the revolving credit facility is calculated as a per annum rate equal to LIBOR plus 2.00%, as defined.

We can draw upon this line as long as certain restrictive covenants are maintained. Under our amended and restatement Credit Agreement, we are required to maintain compliance with a minimum consolidated tangible net worth covenant, as defined, and a maximum consolidated total capitalization ratio covenant, as defined. In addition, Stifel, our broker-dealer subsidiary, is required to maintain compliance with a minimum regulatory excess net capital covenant, as defined, and our bank subsidiaries are required to maintain its status as well-capitalized, as defined.

Our revolving credit facility contains customary events of default, including, without limitation, payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to similar obligations, certain events of bankruptcy and insolvency, and judgment defaults. At December 31, 2018, we had no advances on our revolving credit facility and were in compliance with all covenants.

In June 2018, Stifel, our broker-dealer subsidiary, entered into a 364-day, Credit Agreement (“Stifel Credit Facility”) with a maturity date of June 2019 in which the lenders are a number of financial institutions. This committed unsecured borrowing facility provides for maximum borrowings of up to $250.0 million at variable rates of interest.

Under the Stifel Credit Facility, Stifel is required to maintain compliance with a minimum consolidated tangible net worth covenant, as defined, and to maintain compliance with a minimum regulatory excess net capital covenant, as defined.

The Stifel Credit Facility contains customary events of default, including, without limitation, payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to similar obligations, certain events of bankruptcy and insolvency, and judgment defaults. At December 31, 2018, there were no advances on the Stifel Credit Facility and we were in compliance with all covenants.

Federal Home Loan Bank Advances and other secured financing – Stifel Bancorp has borrowing capacity with the Federal Home Loan Bank of $3.9 billion at December 31, 2018 and $59.5 million in federal funds agreements for the purpose of purchasing short-term funds should additional liquidity be needed. At December 31, 2018, outstanding FHLB advances were $540.0 million. Stifel Bancorp is eligible to participate in the Federal Reserve’s discount window program; however, Stifel Bancorp does not view borrowings from the Federal Reserve as a primary means of funding. The credit available in this program is subject to periodic review, may be terminated or reduced at the discretion of the Federal Reserve, and is secured by securities. Stifel Bancorp has borrowing capacity of $1.6 billion with the Federal Reserve’s discount window at December 31, 2018. Stifel Bancorp receives overnight funds from excess cash held in Stifel brokerage accounts, which are deposited into a money market account. These balances totaled $15.2 billion at December 31, 2018. At December 31, 2018, there was $16.1 billion in client money market and FDIC-insured product balances.

Public Offering of Senior Notes – On July 15, 2014, we sold in a registered underwritten public offering, $300.0 million in aggregate principal amount of 4.250% senior notes due July 2024 (the “2014 Notes”). Interest on the 2014 Notes is payable semi-annually in arrears. We may redeem the 2014 Notes in whole or in part, at our option, at a redemption price equal to 100% of their principal amount, plus a “make-whole” premium and accrued and unpaid interest, if any, to the date of redemption. In July 2016, we issued an additional $200.0 million in aggregate principal amount of 4.25% senior notes due 2024. In July 2014, we received a BBB- rating on the 2014 Notes.

On December 1, 2015, we sold in a registered underwritten public offering, $300.0 million in aggregate principal amount of 3.50% senior notes due December 2020 (the “2015 Notes”). Interest on the 2015 Notes is payable semi-annually in arrears. We may redeem the 2015 Notes in whole or in part, at our option, at a redemption price equal to 100% of their principal amount, plus a “make-whole” premium and accrued and unpaid interest, if any, to the date of redemption. In December 2015, we received a BBB- rating on the 2015 Notes.

On October 4, 2017, we completed the pricing of a registered underwritten public offering of $200.0 million in aggregate principal amount of 5.20% senior notes due October 2047. Interest on the senior notes is payable quarterly in arrears on January 15, April 15, July 15, and October 15. On or after October 15, 2022, we may redeem some or all of the senior notes at any time at a redemption price equal to 100% of the principal amount of the notes being redeemed plus accrued interest thereon to the redemption date. On October 27, 2017, we completed the sale of an additional $25.0 million aggregate principal amount of Notes pursuant to the over-allotment option. In October 2017, we received a BBB- rating on the 2017 Notes.

Public Offering of Preferred Stock – On July 11, 2016, we completed an underwritten registered public offering of $150 million perpetual 6.25% Non-Cumulative Perpetual Preferred Stock, Series A. Proceeds from the issuance were used for general corporate purposes.

Credit Rating

We believe our current rating depends upon a number of factors, including industry dynamics, operating and economic environment, operating results, operating margins, earnings trends and volatility, balance sheet composition, liquidity and liquidity management, our capital structure, our overall risk management, business diversification, and our market share and competitive position in the markets in which we operate. Deteriorations in any of these factors could impact our credit rating. A reduction in our credit rating could adversely affect our liquidity and competitive position, increase our incremental borrowing costs, limit our access to the capital markets, or trigger our obligations under certain financial agreements. As such, we may not be able to successfully obtain additional outside financing to fund our operations on favorable terms, or at all.

We believe our existing assets, a significant portion of which are liquid in nature, together with the funds from operations, available informal short-term credit arrangements, and our ability to raise additional capital will provide sufficient resources to meet our present and anticipated financing needs.

Use of Capital Resources – On March 19, 2018, the Company completed the acquisition of Ziegler, a privately held investment bank, capital markets and proprietary investments firm that had 55 private client advisors in five states that managed approximately $5 billion in client assets. Ziegler provided its clients with capital raising, strategic advisory services, equity and fixed income sales & trading and research. The acquisition was funded with cash from operations.

On August 31, 2018, the Company completed the acquisition of BBI and its wholly owned subsidiary, The Business Bank of St. Louis, a full-service banking facility with approximately $600.0 million in assets that operates from a single location. Upon the closing of the transaction, the Business Bank of St. Louis was renamed “Stifel Bank” and Business Bancshares, Inc. was renamed “Stifel Bancorp, Inc.” Stifel Bancorp is the holding company for Stifel Bank & Trust, and its wholly owned subsidiaries, and Stifel Bank. Under the terms of the merger agreement, each outstanding share of BBI common stock (except for shares of BBI common stock held by BBI as treasury stock) were converted into the right to receive 0.705 shares of our company’s common stock, with fractional shares settled with cash. We issued approximately 2.0 million shares for acquisition of BBI.

On October 1, 2018, the Company completed the acquisition of Rand, an independent investment adviser that provides comprehensive wealth management and investment counsel services to individuals, families, and institutions. The acquisition was funded with cash from operations.

⁽¹⁾ Notes issued in conjunction with the acquisitions of City Securities in 2017 and Ziegler Wealth Management in 2018.

We have paid $120.3 million in the form of upfront notes to financial advisors for transition pay during the year ended December 31, 2018. As we continue to take advantage of the opportunities created by market displacement and as competition for skilled professionals in the industry increases, we may decide to devote more significant resources to attracting and retaining qualified personnel.

We utilize transition pay, principally in the form of upfront demand notes, to aid financial advisors, who have elected to join our firm, to supplement their lost compensation while transitioning their customers’ accounts to the Stifel platform. The initial value of the notes is determined primarily by the financial advisors’ trailing production and assets under management. These notes are generally forgiven over a five- to ten-year period based on production. The future estimated amortization expense of the upfront notes, assuming current-year production levels and static growth for the years ended December 31, 2019, 2020, 2021, 2022, 2023, and thereafter, is $100.5 million, $67.5 million, $57.2 million, $50.6 million, $41.9 million, and $90.7 million, respectively. These estimates could change if we continue to grow our business through expansion or experience increased production levels.

We maintain several incentive stock award plans that provide for the granting of stock options, stock appreciation rights, restricted stock, performance awards, stock units, and debentures to our employees. Historically, we have granted stock units to our employees as part of our retention program. In response to the Tax Legislation that was enacted in December 2017, the Company offered certain employees the opportunity to participate in the conversion of certain restricted stock units into restricted stock pursuant to a Modification Award Agreement. A restricted stock unit or restricted stock award represents the right to receive a share of common stock from our company at a designated time in the future without cash payment by the employee and is issued in lieu of cash incentive, principally for deferred compensation and employee retention plans. The restricted stock units or restricted stock awards generally vest over the next one to ten years after issuance and are distributed at predetermined future payable dates once vesting occurs. At December 31, 2018, the total number of restricted stock units and restricted stock outstanding was 16.4 million, of which 14.1 million were unvested. At December 31, 2018, there was approximately $297.4 million of unrecognized compensation cost for restricted stock units and restricted stock, which is expected to be recognized over a weighted-average period of 2.8 years.

The future estimated compensation expense of the unvested restricted stock units and restricted stock, assuming current year forfeiture levels and static growth for the years ended December 31, 2019, 2020, 2021, 2022, 2023, and thereafter, is $82.2 million, $72.6 million, $56.6 million, $43.6 million, $22.7 million, and $19.7 million, respectively. These estimates could change if our forfeitures change from historical levels.

Net Capital Requirements – We operate in a highly regulated environment and are subject to capital requirements, which may limit distributions to our company from our subsidiaries. Distributions from our broker-dealer subsidiaries are subject to net capital rules. These subsidiaries have historically operated in excess of minimum net capital requirements. However, if distributions were to be limited in the future due to the failure of our subsidiaries to comply with the net capital rules or a change in the net capital rules, it could have a material and adverse effect to our company by limiting our operations that require intensive use of capital, such as underwriting or trading activities, or limit our ability to implement our business and growth strategies, pay interest on and repay the principal of our debt, and/or repurchase our common stock. Our non-broker-dealer subsidiaries, Stifel Bank & Trust and Stifel Bank, are also subject to various regulatory capital requirements administered by the federal banking agencies. Our broker-dealer subsidiaries and our bank subsidiaries have consistently operated in excess of their capital adequacy requirements.

At December 31, 2018, Stifel had net capital of $342.7 million, which was 20.9% of aggregate debit items and $310.0 million in excess of its minimum required net capital. At December 31, 2018, all of our broker-dealer subsidiaries’ net capital exceeded the minimum net capital required under the SEC rule. At December 31, 2018, SNEL’s capital and reserves were in excess of the financial resources requirement under the rules of the FCA. At December 31, 2018, our bank subsidiaries considered well capitalized under the regulatory framework for prompt corrective action. See Note 19 of the Notes to Consolidated Financial Statements for details of our regulatory capital requirements.

Critical Accounting Policies and Estimates

In preparing our consolidated financial statements in accordance with U.S. generally accepted accounting principles and pursuant to the rules and regulations of the SEC, we make assumptions, judgments, and estimates that affect the reported amounts of assets, liabilities, revenues, and expenses, and related disclosures of contingent assets and liabilities. We base our assumptions, judgments, and estimates on historical experience and various other factors that we believe to be reasonable under the circumstances. Actual

61

results could differ materially from these estimates under different assumptions or conditions. On a regular basis, we evaluate our assumptions, judgments, and estimates. We also discuss our critical accounting policies and estimates with the Audit Committee of the Board of Directors.

We believe that the assumptions, judgments, and estimates involved in the accounting policies described below have the greatest potential impact on our consolidated financial statements. These areas are key components of our results of operations and are based on complex rules that require us to make assumptions, judgments, and estimates, so we consider these to be our critical accounting policies. Historically, our assumptions, judgments, and estimates relative to our critical accounting policies and estimates have not differed materially from actual results.

For a full description of these and other accounting policies, see Note 2 of the Notes to Consolidated Financial Statements.

Valuation of Financial Instruments

We measure certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents, trading securities owned, available-for-sale securities, investments, trading securities sold, but not yet purchased, and derivatives.

Trading securities owned and pledged and trading securities sold, but not yet purchased, are carried at fair value on the consolidated statements of financial condition, with unrealized gains and losses reflected on the consolidated statements of operations.

The fair value of a financial instrument is defined as the price 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, or an exit price. The degree of judgment used in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Financial instruments with readily available active quoted prices or for which fair value can be measured from actively quoted prices in active markets generally have more pricing observability and less judgment used in measuring fair value. Conversely, financial instruments rarely traded or not quoted have less pricing observability and are measured at fair value using valuation models that require more judgment. Pricing observability is impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, the characteristics specific to the transaction, and overall market conditions generally.

When available, we use observable market prices, observable market parameters, or broker or dealer quotes (bid and ask prices) to derive the fair value of financial instruments. In the case of financial instruments transacted on recognized exchanges, the observable market prices represent quotations for completed transactions from the exchange on which the financial instrument is principally traded.

A substantial percentage of the fair value of our trading securities and other investments owned, trading securities pledged as collateral, and trading securities sold, but not yet purchased, are based on observable market prices, observable market parameters, or derived from broker or dealer prices. The availability of observable market prices and pricing parameters can vary from product to product. Where available, observable market prices and pricing or market parameters in a product may be used to derive a price without requiring significant judgment. In certain markets, observable market prices or market parameters are not available for all products, and fair value is determined using techniques appropriate for each particular product. These techniques involve some degree of judgment.

For investments in illiquid or privately held securities that do not have readily determinable fair values, the determination of fair value requires us to estimate the value of the securities using the best information available. Among the factors we consider in determining the fair value of investments are the cost of the investment, terms and liquidity, developments since the acquisition of the investment, the sales price of recently issued securities, the financial condition and operating results of the issuer, earnings trends and consistency of operating cash flows, the long-term business potential of the issuer, the quoted market price of securities with similar quality and yield that are publicly traded, and other factors generally pertinent to the valuation of investments. In instances where a security is subject to transfer restrictions, the value of the security is based primarily on the quoted price of a similar security without restriction but may be reduced by an amount estimated to reflect such restrictions. The fair value of these investments is subject to a high degree of volatility and may be susceptible to significant fluctuation in the near term, and the differences could be material.

We have categorized our financial instruments measured at fair value into a three-level classification in accordance with Topic 820, “Fair Value Measurement and Disclosures.” Fair value measurements of financial instruments that use quoted prices in active markets for identical assets or liabilities are generally categorized as Level 1, and fair value measurements of financial instruments that have no direct observable levels are generally categorized as Level 3. All other fair value measurements of financial instruments that do not fall within the Level 1 or Level 3 classification are considered Level 2. The lowest level input that is significant to the fair value measurement of a financial instrument is used to categorize the instrument and reflects the judgment of management.

Level 3 financial instruments have little to no pricing observability as of the report date. These financial instruments do not have active two-way markets and 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. We have identified Level 3 financial instruments to include certain asset-backed securities, consisting of collateral loan obligation securities, that have experienced low volumes of executed transactions, certain corporate bonds and equity securities where there was less frequent or nominal market activity, investments in private equity funds, and auction rate securities for which the market has been dislocated and largely ceased to function. Our Level 3 asset-backed

62

securities are valued using cash flow models that utilize unobservable inputs. Level 3 corporate bonds are valued using prices from comparable securities. Equity securities with unobservable inputs are valued using management’s best estimate of fair value, where the inputs require significant management judgment. Auction rate securities are valued based upon our expectations of issuer redemptions and using internal models.

Investments in Partnerships

Investments in partnerships and other investments include our general and limited partnership interests in investment partnerships and direct investments in non-public companies. These interests are carried at estimated fair value. The net assets of investment partnerships consist primarily of investments in non-marketable securities. The underlying investments held by such partnerships and direct investments in non-public companies are valued based on estimated fair value ultimately determined by us in our capacity as general partner or investor and, in the case of an investment in an unaffiliated investment partnership, are based on financial statements prepared by an unaffiliated general partner. Due to the inherent uncertainty of valuation, fair values of these non-marketable investments may differ from the values that would have been used had a ready market existed for these investments, and the differences could be material. Increases and decreases in estimated fair value are recorded based on underlying information of these non-public company investments, including third-party transactions evidencing a change in value, market comparable, operating cash flows and financial performance of the companies, trends within sectors and/or regions, underlying business models, expected exit timing and strategy, and specific rights or terms associated with the investment, such as conversion features and liquidation preferences. In cases where an estimate of fair value is determined based on financial statements prepared by an unaffiliated general partner, such financial statements are generally unaudited other than audited year-end financial statements. Upon receipt of audited financial statements from an investment partnership, we adjust the fair value of the investments to reflect the audited partnership results if they differ from initial estimates. We also perform procedures to evaluate fair value estimates provided by unaffiliated general partners. At December 31, 2018, we had commitments to invest in affiliated and unaffiliated investment partnerships of $2.5 million. These commitments are generally called as investment opportunities are identified by the underlying partnerships. These commitments may be called in full at any time.

The investment partnerships in which we are general partner may allocate carried interest and make carried interest distributions, which represent an additional allocation of net realized and unrealized gains to the general partner if the partnerships’ investment performance reaches a threshold as defined in the respective partnership agreements. These allocations are recognized in revenue as realized and unrealized gains and losses on investments in partnerships. Our recognition of allocations of carried interest gains and losses from the investment partnerships in revenue is not adjusted to reflect expectations about future performance of the partnerships.

As the investment partnerships realize proceeds from the sale of their investments, they may make cash distributions as provided for in the partnership agreements. Distributions that result from carried interest may subsequently become subject to claw back if the fair value of private equity partnership assets subsequently decreases in fair value. To the extent these decreases in fair value and allocated losses exceed our capital account balance, a liability is recorded by us. These liabilities for claw back obligations are not required to be paid to the investment partnerships until the dissolution of such partnerships, and are only required to be paid if the cumulative amounts actually distributed exceed the amount due based on the cumulative operating results of the partnerships.

We earn fees from the investment partnerships that we manage or of which we are a general partner. Such management fees are generally based on the net assets or committed capital of the underlying partnerships. We have agreed, in certain cases, to waive management fees, in lieu of making a cash contribution, in satisfaction of our general partner investment commitments to the investment partnerships. In these cases, we generally recognize our management fee revenues at the time when we are allocated a special profit interest in realized gains from these partnerships.

Contingencies

We are involved in various pending and potential legal proceedings related to our business, including litigation, arbitration, and regulatory proceedings. Some of these matters involve claims for substantial amounts, including claims for punitive damages. We have, after consultation with outside legal counsel and consideration of facts currently known by management, recorded estimated losses in accordance with Topic 450 (“Topic 450”), “Contingencies,” to the extent that claims are probable of loss and the amount of the loss can be reasonably estimated. The determination of these reserve amounts requires us to use significant judgment, and our final liabilities may ultimately be materially different. This determination is inherently subjective, as it requires estimates that are subject to potentially significant revision as more information becomes available and due to subsequent events. In making these determinations, we consider many factors, including, but not limited to, the loss and damages sought by the plaintiff or claimant, the basis and validity of the claim, the likelihood of a successful defense against the claim, and the potential for, and magnitude of, damages or settlements from such pending and potential litigation and arbitration proceedings, and fines and penalties or orders from regulatory agencies. See Item 3, “Legal Proceedings,” in Part I of this report for information on our legal, regulatory, and arbitration proceedings.

Allowance for Loan Losses

We regularly review the loan portfolio and have established an allowance for loan losses for inherent losses estimated to have occurred in the loan portfolio through a provision for loan losses charged to income. In providing for the allowance for loan losses, we consider historical loss experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s

63

ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available.

A loan is considered impaired when, based on current information and events, it is probable that the scheduled payments of principal or interest when due, according to the contractual terms of the loan agreement, will not be collectible. Factors considered in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. We determine the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed.

Once a loan is determined to be impaired, when principal or interest becomes 90 days past due or when collection becomes uncertain, the accrual of interest and amortization of deferred loan origination fees is discontinued (“non-accrual status”), and any accrued and unpaid interest income is reversed. Loans placed on non-accrual status are returned to accrual status when all delinquent principal and interest payments are collected and the collectability of future principal and interest payments is reasonably assured. Loan losses are charged against the allowance when we believe the uncollectability of a loan balance is certain. Subsequent recoveries, if any, are credited to the allowance for loan loss.

Large groups of smaller balance homogenous loans are collectively evaluated for impairment. Accordingly, we do not separately identify individual consumer and residential loans for impairment measurements. Impairment is measured on a loan-by-loan basis for non-homogeneous loans, and a specific allowance is established for individual loans determined to be impaired. Impairment is measured by comparing the carrying value of the impaired loan to the present value of its expected cash flow discounted at the loan’s effective interest rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent.

Derivative Instruments and Hedging Activities

Our derivative instruments are carried on the consolidated statement of financial condition at fair value. We utilize these derivative instruments to minimize significant unplanned fluctuations in earnings caused by interest rate volatility. Our company’s goal is to manage sensitivity to changes in rates by offsetting the repricing or maturity characteristics of certain assets and liabilities, thereby limiting the impact on earnings. The use of derivative instruments does expose our company to credit and market risk. We manage credit risk through strict counterparty credit risk limits and/or collateralization agreements. At inception, we determine if a derivative instrument meets the criteria for hedge accounting under Topic 815, “Derivatives and Hedging.” Ongoing effectiveness evaluations are made for instruments that are designated and qualify as hedges. If the derivative does not qualify for hedge accounting, no assessment of effectiveness is needed.

Income Taxes

On December 22, 2017, Tax Legislation was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017.

The provision for income taxes and related tax reserves is based on our consideration of known liabilities and tax contingencies for multiple taxing authorities. Known liabilities are amounts that will appear on current tax returns, amounts that have been agreed to in revenue agent revisions as the result of examinations by the taxing authorities, and amounts that will follow from such examinations but affect years other than those being examined. Tax contingencies are liabilities that might arise from a successful challenge by the taxing authorities taking a contrary position or interpretation regarding the application of tax law to our tax return filings. Factors considered in estimating our liability are results of tax audits, historical experience, and consultation with tax attorneys and other experts.

Accounting Standards Codification (“ASC”) Topic 740 (“Topic 740”), “Income Taxes,” clarifies the accounting for uncertainty in income taxes recognized in an entity’s financial statements and prescribed recognition threshold and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on a tax return. The impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more likely than not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Additionally, Topic 740 provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition.

Goodwill and Intangible Assets

Under the provisions of ASC Topic 805, “Business Combinations,” we record all assets and liabilities acquired in purchase acquisitions, including goodwill and other intangible assets, at fair value. Determining the fair value of assets and liabilities requires certain estimates.

64

Goodwill for certain acquisitions is deductible for tax purposes. The amortization of goodwill for tax purposes creates a cash tax savings due to a reduction in the current taxes payable. We have recorded cash tax savings for the year ending December 31, 2018, of $6.5 million and anticipate cumulative future cash savings of $53.3 million as of result of the tax amortization of goodwill.

In accordance with ASC Topic 350, “Intangibles – Goodwill and Other,” indefinite-life intangible assets and goodwill are not amortized. Rather, they are subject to impairment testing on an annual basis, or more often if events or circumstances indicate there may be impairment. This test involves assigning tangible assets and liabilities as well as identified intangible assets and goodwill to reporting units and comparing the fair value of each reporting unit to its carrying amount. If the fair value is less than the carrying amount, a further test is required to measure the amount of the impairment.

We test goodwill for impairment on an annual basis and on an interim basis when certain events or circumstances exist. We test for impairment at the reporting unit level, which is generally at the level of or one level below our company’s business segments. For both the annual and interim tests, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads 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 or circumstances, we determine it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then performing the two-step impairment test is not required. However, if we conclude otherwise, we are then required to perform the first step of the two-step impairment test. Goodwill impairment is determined by comparing the estimated fair value of a reporting unit with its respective carrying value. If the estimated fair value exceeds the carrying value, goodwill at the reporting unit level is not deemed to be impaired. If the estimated fair value is below carrying value, however, further analysis is required to determine the amount of the impairment. Additionally, if the carrying value of a reporting unit is zero or a negative value and it is determined that it is more likely than not the goodwill is impaired, further analysis is required. The estimated fair values of the reporting units are derived based on valuation techniques we believe market participants would use for each of the reporting units. Our annual goodwill impairment testing was completed as of October 1, 2018, with no impairment charges resulting from the annual impairment tests.

The goodwill impairment test requires us to make judgments in determining what assumptions to use in the calculation. Assumptions, judgments, and estimates about future cash flows and discount rates are complex and often subjective. They can be affected by a variety of factors, including, among others, economic trends and market conditions, changes in revenue growth trends or business strategies, unanticipated competition, discount rates, technology, or government regulations. In assessing the fair value of our reporting units, the volatile nature of the securities markets and industry requires us to consider the business and market cycle and assess the stage of the cycle in estimating the timing and extent of future cash flows. In addition to discounted cash flows, we consider other information, such as public market comparables and multiples of recent mergers and acquisitions of similar businesses. Although we believe the assumptions, judgments, and estimates we have made in the past have been reasonable and appropriate, different assumptions, judgments, and estimates could materially affect our reported financial results.

Identifiable intangible assets, which are amortized over their estimated useful lives, are tested for potential impairment whenever events or changes in circumstances suggest that the carrying value of an asset or asset group may not be fully recoverable.

Off-Balance Sheet Arrangements

Information concerning our off-balance sheet arrangements is included in Note 23 of the Notes to Consolidated Financial Statements. Such information is hereby incorporated by reference.

Dilution

As of December 31, 2018, there were 16,388,116 outstanding restricted stock unit and restricted stock grants. A restricted stock unit represents the right to receive a share of common stock from our company at a designated time in the future without cash payment by the employee and is issued in lieu of cash incentive, principally for deferred compensation and employee retention plans. The restricted stock units vest on an annual basis over the next one to ten years and are distributable, if vested, at future specified dates. Restricted stock awards are restricted as to sale or disposition. These restrictions lapse over the next one to five years. Of the outstanding restricted stock units and restricted stock awards, 2,271,277 shares are currently vested and 14,116,839 are unvested. Assuming vesting requirements are met, the Company anticipates that 2,359,423 shares under these awards will be distributed in 2019, 2,181,723 will vest in 2020, 2,503,329 will vest in 2021, and the balance of 7,072,364 will be distributed thereafter.

An employee will realize income as a result of an award of stock units at the time shares are distributed in an amount equal to the fair market value of the shares at that time, and we are entitled to a corresponding tax deduction in the year of vesting in some instances, or delivery in other instances. Unless an employee elects to satisfy the withholding in another manner, either by paying the amount in cash or by delivering shares of Stifel Financial Corp. common stock already owned by the individual for at least six months, we may satisfy tax withholding obligations on income associated with the grants by reducing the number of shares otherwise deliverable in connection with the awards. The reduction will be calculated based on a current market price of our common stock. Based on current

65

tax law, we anticipate that the shares issued when the awards are paid to the employees will be reduced by approximately 35% to satisfy the maximum withholding obligations, so that approximately 65% of the total restricted stock units that are distributable in any particular year will be converted into issued and outstanding shares.

It has been our practice historically to satisfy almost all tax withholding obligations on income associated with the grants by reducing the number of shares otherwise deliverable in connection with the awards. We anticipate that practice will continue, as recently our Compensation Committee made a determination to satisfy tax withholding obligations through the cancellation of shares subject to an award. In addition, the plan pursuant to which we issue restricted stock units and restricted stock awards permits us to elect to settle certain awards entirely in cash, and we may elect to do so as those awards vest and become deliverable.

⁽²⁾ See Note 15 of the Notes to the Consolidated Financial Statements for further discussion of our Capital Trusts.

⁽³⁾ Commitments to extend credit include commitments to originate loans, outstanding standby letters of credit, and lines of credit which may expire without being funded and, as such, do not represent estimates of future cash flow.

⁽⁴⁾ Information concerning our acquisitions is included in Note 3 of the Notes to the Consolidated Financial Statements. Such information is hereby incorporated by reference.

The amounts presented in the table above may not necessarily reflect our actual future cash funding requirements, because the actual timing of the future payments made may vary from the stated contractual obligation. In addition, due to the uncertainty with respect to the timing of future cash flows associated with our unrecognized tax benefits as of December 31, 2018, we are unable to make reasonably reliable estimates of the period of cash settlement with the respective taxing authority. Therefore, $0.2 million of unrecognized tax benefits have been excluded from the contractual obligation table above. See Note 24 to the consolidated financial statements for a discussion of income taxes.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Risk Management

Risks are an inherent part of our business and activities. Management of these risks is critical to our soundness and profitability. Risk management at our company is a multi-faceted process that requires communication, judgment, and knowledge of financial products and markets. Our senior management group takes an active role in the risk management process and requires specific administrative and business functions to assist in the identification, assessment, monitoring, and control of various risks. The principal risks involved in our business activities are: market (interest rates and equity prices), credit, capital and liquidity, operational, and regulatory and legal. We have adopted policies and procedures concerning risk management, and our Board of Directors, in exercising its oversight of management’s activities, conducts periodic reviews and discussions with management regarding the guidelines and policies governing the processes by which risk assessment and risk management are handled.

Market Risk

The potential for changes in the value of financial instruments owned by our company resulting from changes in interest rates and equity prices is referred to as “market risk.” Market risk is inherent to financial instruments, and accordingly, the scope of our market risk management procedures includes all market risk-sensitive financial instruments.

We trade tax-exempt and taxable debt obligations, including U.S. treasury bills, notes, and bonds; U.S. government agency and municipal notes and bonds; bank certificates of deposit; mortgage-backed securities; and corporate obligations. We are also an active

66

market-maker in over-the-counter equity securities. In connection with these activities, we may maintain inventories in order to ensure availability and to facilitate customer transactions.

Changes in value of our financial instruments may result from fluctuations in interest rates, credit ratings, equity prices, and the correlation among these factors, along with the level of volatility.

We manage our trading businesses by product and have established trading departments that have responsibility for each product. The trading inventories are managed with a view toward facilitating client transactions, considering the risk and profitability of each inventory position. Position limits in trading inventory accounts are established and monitored on a daily basis. We monitor inventory levels and results of the trading departments, as well as inventory aging, pricing, concentration, and securities ratings.

We are also exposed to market risk based on our other investing activities. These investments consist of investments in private equity partnerships, start-up companies, venture capital investments, and zero coupon U.S. government securities and are included under the caption “Investments” on the consolidated statements of financial condition.

Interest Rate Risk

We are exposed to interest rate risk as a result of maintaining inventories of interest rate-sensitive financial instruments and from changes in the interest rates on our interest-earning assets (including client loans, stock borrow activities, investments, inventories, and resale agreements) and our funding sources (including client cash balances, stock lending activities, bank borrowings, and repurchase agreements), which finance these assets. The collateral underlying financial instruments at the broker-dealer is repriced daily, thus requiring collateral to be delivered as necessary. Interest rates on client balances and stock borrow and lending produce a positive spread to our company, with the rates generally fluctuating in parallel.

We manage our inventory exposure to interest rate risk by setting and monitoring limits and, where feasible, hedging with offsetting positions in securities with similar interest rate risk characteristics. While a significant portion of our securities inventories have contractual maturities in excess of five years, these inventories, on average, turn over several times per year.

Additionally, we monitor, on a daily basis, the Value-at-Risk (“VaR”) in our trading portfolios using a ten-day horizon and report VaR at a 99% confidence level. VaR is a statistical technique used to estimate the probability of portfolio losses based on the statistical analysis of historical price trends and volatility. This model assumes that historical changes in market conditions are representative of future changes, and trading losses on any given day could exceed the reported VaR by significant amounts in unusually volatile markets. Further, the model involves a number of assumptions and inputs. While we believe that the assumptions and inputs we use in our risk model are reasonable, different assumptions and inputs could produce materially different VaR estimates.

The following table sets forth the high, low, and daily average VaR for our trading portfolios during the year ended December 31, 2018, and the daily VaR at December 31, 2018 and 2017 (in thousands): 

	December 31, 2018						VaR Calculation at December31,

Stifel Bancorp’s interest rate risk is principally associated with changes in market interest rates related to residential, consumer, and commercial lending activities, as well as FDIC-insured deposit accounts to customers of our broker-dealer subsidiaries and to the general public.

Our primary emphasis in interest rate risk management for Stifel Bancorp is the matching of assets and liabilities of similar cash flow and repricing time frames. This matching of assets and liabilities reduces exposure to interest rate movements and aids in stabilizing positive interest spreads. Stifel Bancorp has established limits for acceptable interest rate risk and acceptable portfolio value risk. To ensure that Stifel Bancorp is within the limits established for net interest margin, an analysis of net interest margin based on various shifts in interest rates is prepared each quarter and presented to Stifel Bancorp’s Board of Directors. Stifel Bancorp utilizes a third-party model to analyze the available data.

The following table illustrates the estimated change in net interest margin at December 31, 2018, based on shifts in interest rates of up to positive 200 basis points and negative 200 basis points: 

Hypothetical Change in Interest Rates	Projected Change in Net Interest Margin
+200		11.8	%
+100		5.7
0		—
-100		(7.7	)

We maintain a risk management strategy that incorporates the use of derivative instruments to minimize significant unplanned fluctuations in earnings caused by interest rate volatility. Our goal is to manage sensitivity to changes in rates by hedging the maturity characteristics of Fed funds-based affiliated deposits, thereby limiting the impact on earnings. By using derivative instruments, we are exposed to credit and market risk on those derivative positions. We manage the market risk associated with interest rate contracts by establishing and monitoring limits as to the types and degree of risk that may be undertaken. Our interest rate hedging strategies may not work in all market environments and, as a result, may not be effective in mitigating interest rate risk.

Equity Price Risk

We are exposed to equity price risk as a consequence of making markets in equity securities. We attempt to reduce the risk of loss inherent in our inventory of equity securities by monitoring those security positions constantly throughout each day.

Our equity securities inventories are repriced on a regular basis, and there are no unrecorded gains or losses. Our activities as a dealer are client-driven, with the objective of meeting clients’ needs while earning a positive spread.

Credit Risk

We are engaged in various trading and brokerage activities, with the counterparties primarily being broker-dealers. In the event counterparties do not fulfill their obligations, we may be exposed to risk. The risk of default depends on the creditworthiness of the counterparty or issuer of the instrument. We manage this risk by imposing and monitoring position limits for each counterparty, monitoring trading counterparties, conducting regular credit reviews of financial counterparties, reviewing security concentrations, holding and marking to market collateral on certain transactions, and conducting business through clearing organizations, which guarantee performance.

Our client activities involve the execution, settlement, and financing of various transactions on behalf of our clients. Client activities are transacted on either a cash or margin basis. Credit exposure associated with our private client business consists primarily of customer margin accounts, which are monitored daily and are collateralized. We monitor exposure to industry sectors and individual securities and perform analyses on a regular basis in connection with our margin lending activities. We adjust our margin requirements if we believe our risk exposure is not appropriate based on market conditions.

We have accepted collateral in connection with resale agreements, securities borrowed transactions, and customer margin loans. Under many agreements, we are permitted to sell or repledge these securities held as collateral and use these securities to enter into securities lending arrangements or to deliver to counterparties to cover short positions. At December 31, 2018, the fair value of securities accepted as collateral where we are permitted to sell or repledge the securities was $2.4 billion and the fair value of the collateral that had been sold or repledged was $535.4 million.

By using derivative instruments, we are exposed to credit and market risk on those derivative positions. Credit risk is equal to the fair value gain in a derivative, if the counterparty fails to perform. When the fair value of a derivative contract is positive, this generally indicates that the counterparty owes our company and, therefore, creates a repayment risk for our company. When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, have no repayment risk. We minimize the credit (or repayment) risk in derivative instruments by entering into transactions with high-quality counterparties that are reviewed periodically by senior management.

Stifel Bancorp extends credit to individual and commercial borrowers through a variety of loan products, including residential and commercial mortgage loans, home equity loans, construction loans, and non-real-estate commercial and consumer loans. Bank loans are generally collateralized by real estate, real property, or other assets of the borrower. Stifel Bancorp’s loan policy includes criteria

68

to adequately underwrite, document, monitor, and manage credit risk. Underwriting requires reviewing and documenting the fundamental characteristics of credit, including character, capacity to service the debt, capital, conditions, and collateral. Benchmark capital and coverage ratios are utilized, which include liquidity, debt service coverage, credit, working capital, and capital to asset ratios. Lending limits are established to include individual, collective, committee, and board authority. Monitoring credit risk is accomplished through defined loan review procedures, including frequency and scope.

We are subject to concentration risk if we hold large positions, extend large loans to, or have large commitments with a single counterparty, borrower, or group of similar counterparties or borrowers (i.e., in the same industry). Securities purchased under agreements to resell consist of securities issued by the U.S. government or its agencies. Receivables from and payables to clients and stock borrow and lending activities, both with a large number of clients and counterparties, and any potential concentration are carefully monitored. Stock borrow and lending activities are executed under master netting agreements, which gives our company right of offset in the event of counterparty default. Inventory and investment positions taken and commitments made, including underwritings, may involve exposure to individual issuers and businesses. We seek to limit this risk through careful review of counterparties and borrowers and the use of limits established by our senior management group, taking into consideration factors including the financial strength of the counterparty, the size of the position or commitment, the expected duration of the position or commitment, and other positions or commitments outstanding.

Operational Risk

Operational risk generally refers to the risk of loss resulting from our operations, including, but not limited to, business disruptions, improper or unauthorized execution and processing of transactions, deficiencies in our technology or financial operating systems and inadequacies or breaches in our control processes including cyber security incidents (see Item 1A, Risk Factors in this report for a discussion of certain cyber security risks).

We operate different businesses in diverse markets and are reliant on the ability of our employees and systems to process a large number of transactions. These risks are less direct than credit and market risk, but managing them is critical, particularly in a rapidly changing environment with increasing transaction volumes. In the event of a breakdown or improper operation of systems or improper action by employees, we could suffer financial loss, regulatory sanctions, and damage to our reputation. In order to mitigate and control operational risk, we have developed and continue to enhance specific policies and procedures that are designed to identify and manage operational risk at appropriate levels throughout the organization and within such departments as Accounting, Operations, Information Technology, Legal, Compliance, and Internal Audit. These control mechanisms attempt to ensure that operational policies and procedures are being followed and that our various businesses are operating within established corporate policies and limits. Business continuity plans exist for critical systems, and redundancies are built into the systems as deemed appropriate.

Regulatory and Legal Risk

Legal risk includes the risk of large numbers of private client group customer claims for sales practice violations. While these claims may not be the result of any wrongdoing, we do, at a minimum, incur costs associated with investigating and defending against such claims. See further discussion on our legal reserves policy under “Critical Accounting Policies and Estimates” in Item 7, Part II and “Legal Proceedings” in Item 3, Part I of this report. In addition, we are subject to potentially sizable adverse legal judgments or arbitration awards, and fines, penalties, and other sanctions for non-compliance with applicable legal and regulatory requirements. We are generally subject to extensive regulation by the SEC, FINRA, and state securities regulators in the different jurisdictions in which we conduct business. As a bank holding company, we are subject to regulation by the Federal Reserve. Our bank subsidiaries are subject to regulation by the FDIC. As a result, we are subject to a risk of loss resulting from failure to comply with banking laws. We have comprehensive procedures addressing issues such as regulatory capital requirements, sales and trading practices, use of and safekeeping of customer funds, the extension of credit, including margin loans, collection activities, money laundering, and record keeping. We act as an underwriter or selling group member in both equity and fixed income product offerings. When acting as lead or co-lead manager, we have potential legal exposure to claims relating to these securities offerings. To manage this exposure, a committee of senior executives review proposed underwriting commitments to assess the quality of the offering and the adequacy of due diligence investigation.

Effects of Inflation

Our assets are primarily monetary, consisting of cash, securities inventory, and receivables from customers and brokers and dealers. These monetary assets are generally liquid and turn over rapidly and, consequently, are not significantly affected by inflation. However, the rate of inflation affects various expenses of our company, such as employee compensation and benefits, communications and office supplies, and occupancy and equipment rental, which may not be readily recoverable in the price of services we offer to our clients. Further, to the extent inflation results in rising interest rates and has other adverse effects upon the securities markets, it may adversely affect our financial position and results of operations.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of Stifel Financial Corp.

Opinion on the Financial Statements

We have audited the accompanying consolidated statements of financial condition of Stifel Financial Corp. (the Company) as of December 31, 2018 and 2017, the related consolidated statements of operations, comprehensive income, changes in shareholders' equity and cash flows for each of the three years in the period ended December 31, 2018, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity with U.S. generally accepted accounting principles.

We also have 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, 2018, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 20, 2019 expressed an unqualified opinion thereon.

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 audits. 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 audits 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 audits 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 audits 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 audits provide a reasonable basis for our opinion.

STIFEL FINANCIAL CORP.

Notes to Consolidated Financial Statements

NOTE 1 – Nature of Operations and Basis of Presentation

Nature of Operations

Stifel Financial Corp. (the “Company”), through its wholly owned subsidiaries, is principally engaged in retail brokerage; securities trading; investment banking; investment advisory; retail, consumer, and commercial banking; and related financial services. Our major geographic area of concentration is throughout the United States, with a growing presence in the United Kingdom and Europe. Our company’s principal customers are individual investors, corporations, municipalities, and institutions.

Basis of Presentation

The consolidated financial statements include Stifel Financial Corp. and its wholly owned subsidiaries, principally Stifel, Nicolaus & Company, Incorporated (“Stifel”), Keefe Bruyette & Woods (“KBW”), and Stifel Bancorp, Inc. (“Stifel Bancorp”). Unless otherwise indicated, the terms “we,” “us,” “our,” or “our company” in this report refer to Stifel Financial Corp. and its wholly owned subsidiaries.

The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles, which require management to make certain estimates and assumptions that affect the reported amounts. We consider significant estimates, which are most susceptible to change and impacted significantly by judgments, assumptions, and estimates, to be: valuation of financial instruments and investments in partnerships, accrual for contingencies, allowance for loan losses, derivative instruments and hedging activities, fair value of goodwill and intangible assets, provision for income taxes and related tax reserves, and forfeitures associated with stock-based compensation. Actual results could differ from those estimates.

Certain amounts from prior periods have been reclassified to conform to the current period’s presentation. The effect of these reclassifications on our company’s previously reported consolidated financial statements was not material.

Consolidation Policies

The consolidated financial statements include the accounts of Stifel Financial Corp. and its subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. For consolidated subsidiaries that are less than wholly owned, the third-party holdings of equity interests are referred to as non-controlling interests. The portion of shareholders’ equity that is attributable to non-controlling interests for such subsidiaries is presented as non-controlling interests, a component of total equity, in the consolidated statements of financial condition.

Our non-controlling interest represents a 27.5% third-party ownership of North Shore Aviation Holdings LLC (“North Shore”), a wholly owned subsidiary of the Company, that through its subsidiary owns 5 airplane engines. See Note 9 for additional information on operating leases.

We also have investments or interests in other entities for which we must evaluate whether to consolidate by determining whether we have a controlling financial interest or are considered to be the primary beneficiary. In determining whether to consolidate these entities, we evaluate whether the entity is a voting interest entity or a variable interest entity (“VIE”). When we do not have a controlling interest in an entity, but we exert significant influence over the entity, we apply the equity method of accounting.

Voting Interest Entity – Voting interest entities are entities that have (i) total equity investment at risk sufficient to fund expected future operations independently, and (ii) equity holders who have the obligation to absorb losses or receive residual returns and the right to make decisions about the entity’s activities. We consolidate voting interest entities when we determine that there is a controlling financial interest, usually ownership of all, or a majority of, the voting interest.

Variable Interest Entity – VIEs are entities that lack one or more of the characteristics of a voting interest entity. We are required to consolidate certain VIEs in which we have the power to direct the activities of the entity and the obligation to absorb significant losses or receive significant benefits. In other cases, we consolidate VIEs when we are deemed to be the primary beneficiary. The primary beneficiary is defined as the entity that has a variable interest, or a combination of variable interests, that maintains control and receives benefits or will absorb losses that are not pro rata with its ownership interests.

The determination as to whether an entity is a VIE is based on the structure and nature of the entity. We also consider other characteristics, such as the ability to influence the decision-making relative to the entity’s activities and how the entity is financed. With the exception of entities eligible for the deferral codified in Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2010-10, “Consolidation: Amendments for Certain Investment Funds” (“ASU 2010-10”) (generally asset managers and investment companies), ASC 810 states that a controlling financial interest in an entity is present when an enterprise has a variable interest, or combination of variable interests, that have both the power to direct the activities of the entity that most significantly impact the entity’s economic performance and the obligation to absorb losses of the entity or the rights to receive benefits from the entity that could potentially be significant to the entity.

80

Entities meeting the deferral provision defined by ASU 2010-10 are evaluated under the historical VIE guidance. Under the historical guidance, a controlling financial interest in an entity is present when an enterprise has a variable interest, or combination of variable interests, that will absorb a majority of the entity’s expected losses, receive a majority of the entity’s expected residual returns, or both. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE.

We determine whether we are the primary beneficiary of a VIE by first performing a qualitative analysis of the VIE’s control structure, expected benefits and losses, and expected residual returns. This analysis includes a review of, among other factors, the VIE’s capital structure, contractual terms, which interests create or absorb benefits or losses, variability, related party relationships, and the design of the VIE. Where a qualitative analysis is not conclusive, we perform a quantitative analysis. We reassess our initial evaluation of an entity as a VIE and our initial determination of whether we are the primary beneficiary of a VIE upon the occurrence of certain reconsideration events. See Note 28 for additional information on VIEs.

NOTE 2 – Summary of Significant Accounting Policies

Cash and Cash Equivalents

We consider money market mutual funds and highly liquid investments with original maturities of three months or less that are not restricted or segregated to be cash equivalents. Cash and cash equivalents include deposits with banks, federal funds sold, money market mutual funds, and certificates of deposit. Cash and cash equivalents also include balances that our bank subsidiaries maintain at the Federal Reserve Bank.

Cash Segregated for Regulatory Purposes

Our broker-dealer subsidiaries are subject to Rule 15c3-3 under the Securities Exchange Act of 1934, which requires our company to maintain cash or qualified securities in a segregated reserve account for the exclusive benefit of its clients. In accordance with Rule 15c3-3, our company has portions of its cash segregated for the exclusive benefit of clients at December 31, 2018.

Brokerage Client Receivables, Net

Brokerage client receivables include receivables of our company’s broker-dealer subsidiaries, which represent amounts due on cash and margin transactions and are generally collateralized by securities owned by clients. Brokerage client receivables, primarily consisting of floating-rate loans collateralized by customer-owned securities, are charged interest at rates similar to other such loans made throughout the industry. The receivables are reported at their outstanding principal balance net of allowance for doubtful accounts. When a brokerage client receivable is considered to be impaired, the amount of the impairment is generally measured based on the fair value of the securities acting as collateral, which is measured based on current prices from independent sources, such as listed market prices or broker-dealer price quotations. Securities owned by customers, including those that collateralize margin or other similar transactions, are not reflected in the consolidated statements of financial condition.

Securities Borrowed and Securities Loaned

Securities borrowed require our company to deliver cash to the lender in exchange for securities and are included in receivables from brokers, dealers, and clearing organizations in the consolidated statements of financial condition. For securities loaned, we generally receive collateral in the form of cash in an amount in excess of the market value of securities loaned. Securities loaned are included in payables to brokers, dealers, and clearing organizations in the consolidated statements of financial condition. We monitor the market value of securities borrowed and loaned on a daily basis, with additional collateral obtained or refunded as necessary. Fees received or paid are recorded in interest revenue or interest expense in the consolidated statements of operations.

Substantially all of these transactions are executed under master netting agreements, which gives us right of offset in the event of counterparty default; however, such receivables and payables with the same counterparty are not set off in the consolidated statements of financial condition.

Securities Purchased Under Agreements to Resell and Repurchase Agreements

Securities purchased under agreements to resell (“resale agreements”) are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. We obtain control of collateral with a market value equal to or in excess of the principal amount loaned and accrued interest under resale agreements. These agreements are short-term in nature and are generally collateralized by U.S. government securities, U.S. government agency securities, and corporate bonds. We value collateral on a daily basis, with additional collateral obtained when necessary to minimize the risk associated with this activity.

Securities sold under agreements to repurchase (“repurchase agreements”) are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. We make delivery of securities sold under agreements to repurchase and monitor the value of collateral on a daily basis. When necessary, we will deliver additional collateral.

Financial Instruments

We measure certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents, financial instruments owned, available-for-sale securities, investments, financial instruments sold, but not yet purchased, and derivatives. Other than those

81

separately discussed in the notes to the consolidated financial statements, the remaining financial instruments are generally short-term in nature, and their carrying values approximate fair value.

The fair value of a financial instrument is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., “the exit price”) in an orderly transaction between market participants at the measurement date. We have categorized our financial instruments measured at fair value into a three-level classification in accordance with Topic 820, “Fair Value Measurement,” which established a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed 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. The hierarchy is broken down into three levels based on the transparency of inputs as follows:

Level 1 – Quoted prices (unadjusted) are available in active markets for identical assets or liabilities as of the measurement date. A quoted price for an identical asset or liability in an active market provides the most reliable fair value measurement, because it is directly observable to the market.

Level 2 – Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the measurement date. The nature of these financial instruments includes instruments for which quoted prices are available but traded less frequently, derivative instruments whose fair value have been derived using a model where inputs to the model 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 measurement date. These financial instruments do not have two-way markets and 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.

Valuation of Financial Instruments

When available, we use observable market prices, observable market parameters, or broker or dealer prices (bid and ask prices) to derive the fair value of financial instruments. In the case of financial instruments transacted on recognized exchanges, the observable market prices represent quotations for completed transactions from the exchange on which the financial instrument is principally traded.

A substantial percentage of the fair value of our financial instruments owned, available-for-sale securities, investments, and financial instruments sold, but not yet purchased, are based on observable market prices, observable market parameters, or derived from broker or dealer prices. The availability of observable market prices and pricing parameters can vary from product to product. Where available, observable market prices and pricing or market parameters in a product may be used to derive a price without requiring significant judgment. In certain markets, observable market prices or market parameters are not available for all products, and fair value is determined using techniques appropriate for each particular product. These techniques involve some degree of judgment.

For investments in illiquid or privately held securities that do not have readily determinable fair values, the determination of fair value requires us to estimate the value of the securities using the best information available. Among the factors we consider in determining the fair value of investments are the cost of the investment, terms and liquidity, developments since the acquisition of the investment, the sales price of recently issued securities, the financial condition and operating results of the issuer, earnings trends and consistency of operating cash flows, the long-term business potential of the issuer, the quoted market price of securities with similar quality and yield that are publicly traded, and other factors generally pertinent to the valuation of investments. In instances where a security is subject to transfer restrictions, the value of the security is based primarily on the quoted price of a similar security without restriction but may be reduced by an amount estimated to reflect such restrictions. The fair value of these investments is subject to a high degree of volatility and may be susceptible to significant fluctuation in the near term, and the differences could be material.

The degree of judgment used in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Pricing observability is impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, and the characteristics specific to the transaction. Financial instruments with readily available active quoted prices for which fair value can be measured from actively quoted prices generally will have a higher degree of pricing observability and a lesser degree of judgment used in measuring fair value. Conversely, financial instruments rarely traded or not quoted will generally have less, or no, pricing observability and a higher degree of judgment used in measuring fair value. See Note 5 for additional information on how we value our financial instruments.

Available-for-Sale and Held-to-Maturity Securities

Securities available for sale, which are carried at fair value, include U.S. government agency securities; state and municipal securities; agency, non-agency, and commercial mortgage-backed securities; corporate fixed income securities; and asset-backed securities, which primarily includes collateralized loan obligations.

82

Securities held to maturity are recorded at amortized cost based on our company’s positive intent and ability to hold these securities to maturity. Securities held to maturity include agency, commercial, and non-agency mortgage-backed securities, asset-backed securities, consisting of collateralized loan obligation securities and ARS, and corporate fixed income securities.

We evaluate all securities in an unrealized loss position quarterly to assess whether the impairment is other-than-temporary. Our other-than-temporary impairment (“OTTI”) assessment is a subjective process requiring the use of judgments and assumptions. Accordingly, we consider a number of qualitative and quantitative criteria in our assessment, including the extent and duration of the impairment, recent events specific to the issuer and/or industry to which the issuer belongs, the payment structure of the security, external credit ratings and the failure of the issuer to make scheduled interest or principal payments, the value of underlying collateral, current market conditions, and our company’s ability and intent to hold the investment until its value recovers or the securities mature. We may determine that the decline in fair value of an investment is other-than-temporary if our analysis of these factors indicates that we will not recover our investment in the securities.

If we determine that impairment on our debt securities is other-than-temporary and we have made the decision to sell the security or it is more likely than not that we will be required to sell the security prior to recovery of its amortized cost basis, we recognize the entire portion of the impairment in earnings. If we have not made a decision to sell the security and we do not expect that we will be required to sell the security prior to recovery of the amortized cost basis, we recognize only the credit component of OTTI in other operating expenses in the consolidated statements of operations. The remaining unrealized loss due to factors other than credit, or the non-credit component, is recorded in accumulated other comprehensive loss. We determine the credit component based on the difference between the security’s amortized cost basis and the present value of its expected future cash flows, discounted based on the purchase yield. The non-credit component represents the difference between the security’s fair value and the present value of expected future cash flows.

We estimate the portion of loss attributable to credit using a discounted cash flow model. Key assumptions used in estimating the expected cash flows include default rates, loss severity, and prepayment rates. Assumptions used can vary widely based on the collateral underlying the securities and are influenced by factors such as collateral type, loan interest rate, geographical location of the borrower, and borrower characteristics.

Unrealized gains and losses on our available-for-sale securities are reported, net of taxes, in accumulated other comprehensive loss included in shareholders’ equity. Amortization of premiums and accretion of discounts are recorded as interest income in the consolidated statements of operations using the interest method. Realized gains and losses from sales of securities available for sale are determined on a specific identification basis and are included in other income in the consolidated statements of operations in the period they are sold. For securities transferred from available-for-sale to held-to-maturity, carrying value also includes unrealized gains and losses recognized in accumulated other comprehensive loss at the date of transfer. Such unrealized gains or losses are accreted over the remaining life of the security with no impact on future net income.

Loan Classification

We classify loans based on our investment strategy and management’s assessment of our intent and ability to hold loans for the foreseeable future or until maturity. Management’s intent and ability with respect to certain loans may change from time to time depending on a number of factors, including economic, liquidity, and capital conditions. The accounting and measurement framework for loans differs depending on the loan classification. The classification criteria and accounting and measurement framework for bank loans and loans held for sale are described below.

Bank Loans and Allowance for Loan Losses

Bank loans consist of commercial and residential mortgage loans, commercial and industrial loans, stock-secured loans, home equity loans, construction loans, and consumer loans originated or acquired by Stifel Bancorp. Bank loans include those loans that management has the intent and ability to hold and are recorded at outstanding principal adjusted for any charge-offs, allowance for loan losses, deferred origination fees and costs, and purchased discounts. Loan origination costs, net of fees, and premiums and discounts on purchased loans are deferred and recognized over the contractual life of the loan as an adjustment of yield using the interest method. Bank loans are generally collateralized by real estate, real property, marketable securities, or other assets of the borrower. Interest income is recognized using the effective interest rate method, which is based upon the respective interest rates and the average daily asset balance. Discount accretion/premium amortization is recognized using the effective interest rate method, which is based upon the respective interest rate and expected lives of loans.

We regularly review the loan portfolio and have established an allowance for loan losses for inherent losses estimated to have occurred in the loan portfolio through a provision for loan losses charged to other operating expenses in the consolidated statements of operations. In providing for the allowance for loan losses, we consider historical loss experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available.

83

Loans Held for Sale

Loans that we intend to sell or for which we do not have the ability and intent to hold for the foreseeable future are classified as held for sale. Loans held for sale consist of fixed-rate and adjustable-rate residential and multi-family real estate mortgage loans intended for sale. Loans held for sale are stated at lower of cost or market value on an individual loan basis. Declines in market value below cost and any gains or losses on the sale of these assets are recognized in other income in the consolidated statements of operations. Market value is determined based on prevailing market prices for loans with similar characteristics or on sale contract prices. Deferred fees and costs related to these loans are not amortized but are recognized as part of the cost basis of the loan at the time it is sold. Because loans held for sale are reported at lower of cost or market value, an allowance for loan losses is not established for loans held for sale.

Impaired Loans

A loan is considered impaired when, based on current information and events, it is probable that the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement will not be collectible. Factors considered in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. We determine the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed.

We consider a loan a trouble debt restructuring when an existing borrower is granted concessionary rates or terms, which would not otherwise be offered. The concessions granted do not reflect current market conditions for a new loan of similar risk to another borrower in similar financial circumstances.

Once a loan is determined to be impaired, when principal or interest becomes 90 days past due or when collection becomes uncertain, the accrual of interest and amortization of deferred loan origination fees is discontinued (“non-accrual status”) and any accrued and unpaid interest income is reversed. Loans placed on non-accrual status are returned to accrual status when all delinquent principal and interest payments are collected and the collectibility of future principal and interest payments is reasonably assured. Loan losses are charged against the allowance for loan losses when we believe the uncollectibility of a loan balance is certain. Subsequent recoveries, if any, are credited to the allowance for loan losses.

Large groups of smaller balance homogenous loans are collectively evaluated for impairment. Accordingly, we do not separately identify individual consumer and residential loans for impairment measurements. Impairment is measured on a loan-by-loan basis for non-homogeneous loans, and a specific allowance is established for individual loans determined to be impaired. Impairment is measured by comparing the carrying value of the impaired loan to the present value of its expected cash flow discounted at the loan’s effective interest rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent.

Investments

Our broker-dealer subsidiaries report changes in fair value of marketable and non-marketable securities in other income in the consolidated statements of operations. The fair value of marketable investments is generally based on either quoted market or dealer prices. The fair value of non-marketable securities is based on management’s estimate using the best information available, which generally consists of quoted market prices for similar securities and internally developed discounted cash flow models.

Investments in the consolidated statements of financial condition contain investments in securities that are marketable and securities that are not readily marketable. These investments are not included in our broker-dealer trading inventory or available-for-sale or held-to-maturity portfolios and represent the acquiring and disposing of debt or equity instruments for our benefit.

Fixed Assets, Net

Office equipment is depreciated on a straight-line basis over the estimated useful life of the asset of two to seven years. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or the term of the lease. Buildings and building improvements are amortized on a straight-line basis over the estimated useful life of the asset of three to thirty-nine years. Depreciation expense is recorded in occupancy and equipment rental in the consolidated statements of operations. Office equipment, leasehold improvements, and property are stated at cost net of accumulated depreciation and amortization in the consolidated statements of financial condition. Fixed assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable.

Goodwill and Intangible Assets

Goodwill represents the cost of acquired businesses in excess of the fair value of the related net assets acquired. We test goodwill for impairment on an annual basis and on an interim basis when certain events or circumstances exist. We test for impairment at the reporting unit level, which is generally at the level of or one level below our company’s business segments. For both the annual and interim tests, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads 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

84

the totality of events or circumstances, we determine it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then performing the two-step impairment test is not required. However, if we conclude otherwise, we are then required to perform the first step of the two-step impairment test. Goodwill impairment is determined by comparing the estimated fair value of a reporting unit with its respective carrying value. If the estimated fair value exceeds the carrying value, goodwill at the reporting unit level is not deemed to be impaired. If the estimated fair value is below carrying value, however, further analysis is required to determine the amount of the impairment. Additionally, if the carrying value of a reporting unit is zero or a negative value and it is determined that it is more likely than not the goodwill is impaired, further analysis is required. The estimated fair values of the reporting units are derived based on valuation techniques we believe market participants would use for each of the reporting units. The Company performed impairment testing on October 1, 2018 with no impairment charges resulting from the annual impairment tests.

Identifiable intangible assets, which are amortized over their estimated useful lives, are tested for potential impairment whenever events or changes in circumstances suggest that the carrying value of an asset or asset group may not be fully recoverable.

Loans and Advances to Financial Advisors and Other Employees, Net

We offer transition pay, principally in the form of upfront loans, to financial advisors and certain key revenue producers as part of our company’s overall growth strategy. These loans are generally forgiven by a charge to compensation and benefits over a five- to ten-year period if the individual satisfies certain conditions, usually based on continued employment and certain performance standards. We monitor and compare individual financial advisor production to each loan issued to ensure future recoverability. If the individual leaves before the term of the loan expires or fails to meet certain performance standards, the individual is required to repay the balance. In determining the allowance for doubtful receivables from former employees, management considers the facts and circumstances surrounding each receivable, including the amount of the unforgiven balance, the reasons for the terminated employment relationship, and the former employees’ overall financial situation.

Derivative Instruments and Hedging Activities

We recognize all of our derivative instruments at fair value as either assets or liabilities in the consolidated statements of financial condition. These instruments are recorded in other assets or accounts payable and accrued expenses in the consolidated statements of financial condition and in the operating section of the consolidated statements of cash flows as increases or decreases of other assets and accounts payable and accrued expenses. Our company’s policy is not to offset fair value amounts recognized for derivative instruments and fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral arising from derivative instruments recognized at fair value executed with the same counterparty under master netting arrangements. The accounting for changes in the fair value (i.e., gains and losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, we must also designate the hedging instrument or transaction, based upon the exposure being hedged.

For derivative instruments that are designated and qualify as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive loss, net of tax, and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item, if any, is recognized in current earnings during the period of change. We do not use derivatives for trading or speculative purposes and, at December 31, 2018, all of our derivatives are designated as cash flow hedges. See Note 14 for additional details.

Revenue Recognition

Customer securities transactions are recorded on a settlement date basis, with related commission revenues and expenses recorded on a trade date basis. Commission revenues are recorded as the amount charged to the customer, which, in certain cases, may include varying discounts. Principal securities transactions are recorded on a trade date basis. We typically distribute our proprietary equity research products to our client base of institutional investors at no charge. These proprietary equity research products are accounted for as a cost of doing business.

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.

Advisory expenses had historically been deferred until reimbursed by the client, the related fee revenue was recognized or the engagement was 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 has been recognized. All other investment banking advisory related expenses, including expenses incurred related to restructuring assignments, are expensed as incurred.

Underwriting expenses had historically been recorded net of client reimbursements and/or netted against revenues. Under the new revenue standard, all investment banking expenses are recognized as non-interest expense in other operating expenses in the

85

consolidated statements of operations and any expense reimbursements are recognized as investment banking revenues (i.e., expenses are no longer recorded net of client reimbursements and are not netted against revenues).

Asset management and service fees. We earn management and performance fees in connection with investment advisory services provided to institutional and individual clients. Investment advisory fees are charged based on the value of assets in fee-based accounts and are affected by changes in the balances of client assets due to market fluctuations and levels of net new client assets. Fees are charged either in advance based on fixed rates applied to the value of the customers’ account at the beginning of the period or periodically based on contracted rates and account performance. Contracts can be terminated at any time with no incremental payments due to our company upon termination. If the contract is terminated by the customer fees are prorated for the period and fees charged for the post termination period are refundable to the customer.

We earn fees from the investment partnerships that we manage or of which we are a general partner. Such management fees are generally based on the net assets or committed capital of the underlying partnerships. We have agreed, in certain cases, to waive management fees, in lieu of making a cash contribution, in satisfaction of our general partner investment commitments to the investment partnerships. In these cases, we generally recognize our management fee revenues at the time when we are allocated a special profit interest in realized gains from these partnerships.

Direct Financing andOperating Leases

The net investment in direct financing leases is included in other assets in the consolidated balance sheets and consists of the present values of the sum of the future minimum lease payments and estimated residual value of the leased assets. Revenue consists of interest earned on the net investment and is recognized over the lease term as a constant percentage return thereon. The net investment in property on operating leases is included in fixed assets, net in the consolidated balance sheets. Depreciation is recognized, on the straight-line basis, over the lease term to the estimated residual value. Operating lease revenue is recorded on a straight-line basis and is recognized over the lease term in other income. Estimated residual values are established at lease inception utilizing contract terms, past customer experience, and general market data and are reviewed and adjusted, if necessary, on an annual basis. See Note 3 – Acquisitions for further details.

We lease office space and equipment under operating leases. We recognize rent expense related to these operating leases on a straight-line basis over the lease term. The lease term commences on the earlier of the date when we become legally obligated for the rent payments or the date on which we take possession of the property. For tenant improvement allowances and rent holidays, we record a deferred rent liability in accounts payable and accrued expenses in the consolidated statements of financial condition and amortize the deferred rent over the lease term as a reduction to occupancy and equipment rental in the consolidated statements of operations.

Income Taxes

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“Tax Legislation”) was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017.

We compute income taxes using the asset and liability method, under which deferred income taxes are provided for the temporary differences between the financial statement carrying amounts and the tax basis of our company’s assets and liabilities. We establish a valuation allowance for deferred tax assets if it is more likely than not that these items will either expire before we are able to realize their benefits, or that future deductibility is uncertain.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. We recognize interest and penalties related to uncertain tax positions in provision for income taxes in the consolidated statements of operations. See Note 24 for further information regarding income taxes.

Foreign Currency Translation

We consolidate our foreign subsidiaries, which have designated their local currency as their functional currency. Assets and liabilities of these foreign subsidiaries are translated at year-end rates of exchange. Revenues and expenses are translated at an average rate for the period. Gains or losses resulting from translating foreign currency financial statements are reflected in accumulated other comprehensive loss, a separate component of Stifel Financial Corp. shareholders’ equity. Gains or losses resulting from foreign currency transactions are included in other income in the consolidated statements of operations.

Recently Issued Accounting Guidance

Fair Value Measurement

In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The objective of this guidance is to improve the effectiveness of disclosure requirements on fair value measurement by eliminating certain disclosure requirements for fair value measurements for all entities, requiring public entities to disclose certain new

86

information and modifying some disclosure requirements. The accounting update is effective for the fiscal year beginning after December 15, 2019 (January 1, 2020 for our company) and early adoption is permitted. The adoption is not expected to have a material impact on our consolidated financial statements.

Derivatives and Hedging

In August 2017, the FASB issued ASU 2017-12, “Targeted Improvements to Accounting for Hedging Activities,” which amends the hedge accounting recognition and presentation requirements. The accounting update improves the transparency and understandability of information conveyed to financial statement users by better aligning companies’ hedging relationship to their existing risk management strategies, simplifies the application of hedge accounting and increases transparency regarding the scope and results of hedging program. The accounting update is effective for the fiscal year beginning after December 15, 2018 (January 1, 2019 for our company) and early adoption is permitted. The Company will not early adopt this accounting update. We are currently evaluating the impact of the accounting update, but the adoption is not expected to have a material impact on our consolidated financial statements.

Callable debt securities

In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities,” which shortens the amortization period for the premium on certain callable debt securities to the earliest call date. The amendments are applicable to any purchased individual debt security with an explicit and non-contingent call feature that is callable at a fixed price on a preset date. The accounting update is effective for fiscal years beginning after December 15, 2018 (January 1, 2019 for our company) under a modified retrospective approach and early adoption is permitted. We are evaluating the impact the adoption of this new guidance will have on our consolidated financial statements.

Goodwill Impairment Testing

In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. Under the accounting update, the annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, and an impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The accounting update is effective for annual or any interim impairment tests in fiscal years beginning after December 15, 2019 (January 1, 2020 for our company) and early adoption is permitted. We are currently evaluating the impact of the accounting update, but the adoption is not expected to have a material impact on our consolidated financial statements.

Financial Instruments – Credit Losses

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments − Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.”  This accounting update impacts the impairment model for certain financial assets measured at amortized cost by requiring a current expected credit loss (“CECL”) methodology to estimate expected credit losses over the entire life of the financial asset, recorded at inception or purchase. CECL will replace the loss model currently applicable to bank loans, held-to-maturity securities, and other receivables carried at amortized cost.

The accounting update also eliminates the concept of other-than-temporary impairment for available-for-sale securities. Impairments on available-for-sale securities will be required to be recognized in earnings through an allowance, when the fair value is less than amortized cost and a credit loss exists or the securities are expected to be sold before recovery of amortized cost. Under the accounting update, there may be an ability to determine there are no expected credit losses in certain circumstances, e.g., based on collateral arrangements for lending and financing transactions or based on the credit quality of the borrower or issuer.

Overall, the amendments in this accounting update are expected to accelerate the recognition of credit losses for portfolios where CECL models will be applied. The accounting update is effective for fiscal years beginning after December 15, 2019 (January 1, 2020 for our company) with early adoption permitted as of January 1, 2019. We are in the process of developing credit models with the assistance of third-party vendors and assessing process changes that may be required for accounting, reporting and governance to comply with the new credit standard.  We are also currently evaluating the impact of the accounting update, but the adoption is not expected to have a material impact on our consolidated financial statements.

Leases

In February 2016, the FASB issued ASU 2016-02, “Leases,” (“ASU 2016-02”) that requires for leases longer than one year, a lessee recognize in the statements of financial condition a right-of-use asset, representing the right to use the underlying asset for the lease term, and a lease liability, representing the liability to make lease payments. The accounting update also requires that for finance leases, a lessee recognize interest expense on the lease liability, separately from the amortization of the right-of-use asset in the statements of earnings, while for operating leases, such amounts should be recognized as a combined expense. In addition, this accounting update requires expanded disclosures about the nature and terms of lease agreements.

We will adopt ASU 2016-02 utilizing the optional transition approach allowed under ASU 2018-11, “Leases (Topic 842): Targeted Improvements” and applying the package of practical expedients beginning January 1, 2019. This option allows entities to initially

87

apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. By applying ASU 2016-02 at the adoption date, as opposed to at the beginning of the earliest period presented, our reporting for periods prior to January 1, 2019 will continue to be reported in accordance with Leases (Topic 840).

The adoption of this guidance will result in the addition of right-of-use assets and corresponding lease obligations to the consolidated balance sheet and will not have a material impact on the Company’s results of operations or cash flows. Upon adoption, the Company expects to record operating lease right-of-use assets in the range of approximately $600 million to $700 million, representing the present value of future lease payments under operating leases with terms of greater than twelve months, with corresponding operating lease liabilities. These amounts are impacted by certain assumptions around lease renewals and the discount rate used to discount the future lease obligations. We do not believe the standard will materially affect our consolidated statements of income or consolidated statements of cash flows. The standard will have no impact on our debt covenant compliance under our current agreements.

Recently Adopted Accounting Guidance

Comprehensive Income

In February 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” that provides for the reclassification from accumulated other comprehensive income to retained earnings for stranded effects resulting from the Tax Cuts and Jobs Act of 2017. The accounting update is effective for the fiscal year beginning after December 15, 2018 (January 1, 2019 for our company) and early adoption is permitted. We early adopted the guidance in the update on January 1, 2018. The adoption of the accounting update resulted in a reclassification adjustment of $3.1 million related to cash flow hedges and investment portfolio credit risk in our consolidated financial statements.

Statement of Cash Flow

In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flow - Restricted Cash,” which adds or clarifies guidance on the classification and presentation of restricted cash in the statement of cash flows. The accounting update is effective for the fiscal year beginning after December 15, 2017. We adopted the guidance in the update on January 1, 2018. The adoption of the accounting update did not have a material impact on our consolidated statement of cash flows. Upon adoption of the accounting update, we recorded an increase of $17.6 million in net cash provided by operating activities and an increase of $153.8 million in net cash used in operating activities for the years ended December 31, 2017 and 2016, respectively, related to reclassifying the changes in our cash segregated for regulatory purposes and restricted cash balance from operating activities to the cash and cash equivalent balances within the consolidated statements of cash flows.

In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” which amends and clarifies the current guidance to reduce diversity in practice of the classification of certain cash receipts and payments in the consolidated statements of cash flows. The accounting update is effective for the fiscal year beginning after December 31, 2017. We adopted the guidance in the update on January 1, 2018. The adoption of the accounting update did not have a material impact on our consolidated statements of cash flows.

Financial Assets and Financial Liabilities

In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” that changes the income statement impact of equity investments held by an entity, and the recognition of changes in fair value of financial liabilities when the fair value option is elected. The accounting update also amends certain disclosure requirements associated with the fair value of financial instruments. The accounting update is effective for fiscal years beginning after December 15, 2017. We adopted the guidance in the update on January 1, 2018. The adoption of the accounting update did not have a material impact on our consolidated financial statements.

Revenue Recognition

In May 2014, the FASB issued ASU 2014-09, “Revenue From Contracts With Customers (Topic 606),” (“ASU 2014-09”) that supersedes current revenue recognition guidance, including most industry-specific guidance. ASU 2014-09, as amended, requires a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services. The guidance also requires additional disclosures regarding the nature, amount, timing, and uncertainty of revenue that is recognized.

Effective January 1, 2018, the Company adopted ASU 2014-09, which provides accounting guidance on the recognition of revenues from contracts and requires gross presentation of certain costs that were previously offset against revenue. This change was applied prospectively from January 1, 2018 and there is no impact on our previously presented results. The adoption of the new revenue standard resulted in a reduction of beginning retained earnings of $4.2 million after-tax as a cumulative effect of adoption of an accounting change.

88

The impact of adoption is primarily related to investment banking revenues that were previously recognized in prior periods, which are now being deferred under the new revenue standard.

With the adoption of the new revenue recognition standard on January 1, 2018, capital raising and advisory fee revenues are no longer presented net of the related reimbursable deal expenses. As a result, capital raising and advisory fee revenues and other operating expenses are higher in 2018 by an identical $33.8 million, with no impact to net income.

The scope of the accounting update does not apply to revenue associated with financial instruments, and as a result, does not have an impact on the elements of our consolidated statements of operations most closely associated with financial instruments, including principal transaction revenues, interest income, and interest expense.

Share-Based Payments

In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”) that requires an entity to record all excess tax benefits and tax deficiencies as an income tax benefit or expense in the income statement. ASU 2016-09 also requires an entity to elect an accounting policy to either estimate the number of forfeitures or account for forfeitures when they occur. The guidance is effective for fiscal years beginning after December 15, 2016 (January 1, 2017 for our company). We adopted the guidance in the update on January 1, 2017. Cash paid to a tax authority by a company when withholding shares from an employee’s award for tax-withholding purposes are now classified as a financing activity in the accompanying consolidated statement of cash flows (adopted retrospectively). We reclassified $61.6 million from operating activities to financing activities in the accompanying consolidated statement of cash flows for the year ended December 31, 2016 pertaining to shares withheld from employee awards for tax withholding purposes.

89

NOTE 3 – Acquisitions

Rand & Associates

On October 1, 2018, the Company completed the acquisition of Rand & Associates (“Rand”), an independent investment adviser that provides comprehensive wealth management and investment counsel services to individuals, families, and institutions. The acquisition was funded with cash from operations.

The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“ASC Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $8.3 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management segment. Identifiable intangible assets purchased by our company consisted of customer relationships with an acquisition-date fair value of $4.6 million. The allocation of the purchase price of Rand is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets of Rand as of the acquisition date and the identified intangible assets. The final goodwill recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments and the recording of identified intangible assets.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the Rand business and of the hired financial advisors and the conversion of the customer accounts to our platform. Goodwill is expected to be deductible for federal income tax purposes.

We recognized a liability for estimated earn-out payments. These payments will be based on the performance of Rand over a five-year period. The liability for earn-out payments was $4.1 million at December 31, 2018. The contingent consideration accrual is included in accounts payable and accrued expenses in the consolidated statements of financial condition.

Pro forma information is not presented, because the acquisition is not considered to be material, as defined by the SEC. The results of operations of Rand have been included in our results prospectively from the date of acquisition.

Business Bancshares, Inc.

On August 31, 2018, the Company completed the acquisition of Business Bancshares, Inc. (“BBI”) and its wholly owned subsidiary, The Business Bank of St. Louis, a full-service banking facility that operates from a single location. Upon the closing of the transaction, the Business Bank of St. Louis was renamed “Stifel Bank” and Business Bancshares, Inc. was renamed “Stifel Bancorp, Inc.” Stifel Bancorp, Inc. (“Stifel Bancorp”) is the holding company for Stifel Bank & Trust, and its wholly owned subsidiaries, and Stifel Bank. Under the terms of the merger agreement, each outstanding share of BBI common stock (except for shares of BBI common stock held by BBI as treasury stock) were converted into the right to receive 0.705 shares of our company’s common stock, with fractional shares settled with cash. We issued approximately 2.0 million shares for acquisition of BBI.

We acquired approximately $507.8 million of loans, and $85.7 million of other assets (primarily cash and due from banks and investment securities). In addition, we assumed approximately $501.1 million of deposits and $21.9 million of other liabilities. Assets acquired and liabilities assumed were recorded at fair value. The fair values for loans were estimated using discounted cash flow analyses using interest rates currently being offered for loans with similar terms. This value was reduced by an estimate of probable losses and the credit risk associated with the loans. The fair values of deposits were estimated by discounting cash flows using interest rates currently being offered on deposits with similar maturities.

The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $38.4 million of goodwill and intangibles in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management segment. Identifiable intangible assets purchased by our company consisted of core deposits with an acquisition date fair value of $8.6 million. The allocation of the purchase price of BBI is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets of BBI as of the acquisition date and the identified intangible assets. The final goodwill recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments and the recording of identified intangible assets.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the BBI business and its customer base.

Pro forma information is not presented, because the acquisition is not considered to be material, as defined by the SEC. The results of operations of BBI have been included in our results prospectively from the date of acquisition.

Ziegler Wealth Management

On March 19, 2018, the Company completed the acquisition of Ziegler Wealth Management (“Ziegler”), a privately held investment bank, capital markets and proprietary investments firm that had 55 private client advisors in five states that managed approximately $5 billion in client assets. Ziegler provided its clients with capital raising, strategic advisory services, equity and fixed income sales & trading and research. The acquisition was funded with cash from operations.

The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“ASC Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $19.0 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management and Institutional Group segments. Identifiable intangible assets purchased by our company consisted of customer relationships and non-compete agreements with an acquisition-date fair value of $9.5 million.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the Ziegler business and of the hired financial advisors and the conversion of the customer accounts to our platform. Goodwill is expected to be deductible for federal income tax purposes.

Pro forma information is not presented, because the acquisition is not considered to be material, as defined by the SEC. The results of operations of Ziegler have been included in our results prospectively from the date of acquisition.

City Securities Corporation

On January 3, 2017, the Company completed the acquisition of City Financial Corporation and its wholly owned subsidiary, City Securities Corporation, (“City Securities”), an independent investment bank focused primarily on offering wealth management and public finance services across the Midwest. The acquisition was funded with cash from operations and our common stock.

We recorded $7.1 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management and Institutional Group segments. Identifiable intangible assets purchased by our company consisted of customer relationships with an acquisition-date fair value of $4.1 million.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the City Securities’ business and of the hired financial advisors and the conversion of the customer accounts to our platform. Goodwill is not expected to be deductible for federal income tax purposes.

Pro forma information is not presented, because the acquisition is not considered to be material, as defined by the SEC. The results of operations of City Securities have been included in our results prospectively from the date of acquisition.

ISM Capital LLP

On May 3, 2016, the Company completed the acquisition of ISM Capital LLP (“ISM”), an independent investment bank focused on international debt capital markets. The acquisition of ISM adds to the Company’s debt capital markets origination, sales, and research capabilities in Europe, including an end-to-end platform for convertible securities and other equity-linked debt instruments. The acquisition was funded with cash from operations and our common stock, issued out of treasury.

The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“ASC Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities.

Identifiable intangible assets purchased by our company consisted of customer relationships, non-compete, and customer backlog with aggregate acquisition-date fair values of $2.3 million.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of ISM’s business and the addition of an end-to-end platform for convertible securities and other equity-linked debt instruments to our debt capital markets capabilities in Europe. Goodwill is not expected to be deductible for federal income tax purposes.

We recognized a liability for estimated earn-out payments. These payments will be based on ISM’s performance over a three-year period. The liability for earn-out payments was $1.9 million at December 31, 2017. The contingent consideration accrual is included in accounts payable and accrued expenses in the consolidated statements of financial condition. There was no liability for earn-out payments at December 31, 2018.

91

Eaton Partners

On January 4, 2016, we completed the acquisition of Eaton Partners, LLC (“Eaton Partners”), a global fund placement and advisory firm. The acquisition was funded with cash from operations and our common stock, issued out of treasury.

The acquisition was accounted for under the acquisition method of accounting in accordance with Topic 805. Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $72.0 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Institutional Group segment. Identifiable intangible assets purchased by our company consisted of customer relationships, trade name, non-compete, and customer backlog with aggregate acquisition-date fair values of $32.3 million.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of Eaton’s business and from the relationships Eaton has established with private equity firms, hedge funds, high net worth family offices, and institutional investors. Goodwill is deductible for federal income tax purposes.

We recognized a liability for estimated earn-out payments. These payments will be based on Eaton Partner’s performance over a four-year period. The liability for earn-out payments was $40.2 million and $31.2 million at December 31, 2018 and 2017, respectively. The contingent consideration accrual is included in accounts payable and accrued expenses in the consolidated statements of financial condition.

Barclays Wealth and Investment Management, Americas

On December 4, 2015, we completed the purchase of the Barclays Wealth and Investment Management, Americas (“Barclays”), franchise in the U.S. The Company paid purchase consideration that was funded with cash from operations. As part of that transaction, Stifel Bancorp, a wholly owned subsidiary of the Company, acquired approximately $600.0 million of bank loans, at fair value, from Barclays. The fair values for those loans were estimated using discounted cash flow analyses using interest rates currently being offered for loans with similar terms.

The acquisition was accounted for under the acquisition method of accounting in accordance with Topic 805. Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $24.8 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management segment. Identifiable intangible assets purchased by our company consisted of customer relationships, with acquisition-date fair value of $7.3 million.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the hired financial advisors and the conversion of the customer accounts to the Stifel platform. Goodwill is expected to be deductible for federal income tax purposes.

In addition, deferred consideration is payable based on certain revenue generated by Stifel in accordance with the distribution agreement. The deferred consideration of $7.4 million and $15.2 million has been recognized as a liability and is included in accounts payable and accrued expenses in the consolidated statements of financial condition at December 31, 2018 and 2017, respectively.

During 2016, the Company’s Board of Directors removed the continuing service requirements associated with restricted stock units that were granted to certain employees of Barclays in December 2015. As a result, the awards were expensed at date of modification resulting in a charge of $58.6 million during 2016. The fair value of the awards is based upon the closing price of our company’s common stock on the date of the grant of the awards. These charges are included in compensation and benefits in the consolidated statements of operations for the year ended December 31, 2016.

NOTE 5 – Fair Value Measurements

We measure certain financial assets and liabilities at fair value on a recurring basis, including financial instruments owned, available-for-sale securities, investments, financial instruments sold, but not yet purchased, and derivatives.

We generally utilize third-party pricing services to value Level 1 and Level 2 available-for-sale investment securities, as well as certain derivatives designated as cash flow hedges. We review the methodologies and assumptions used by the third-party pricing services and evaluate the values provided, principally by comparison with other available market quotes for similar instruments and/or analysis based on internal models using available third-party market data. We may occasionally adjust certain values provided by the third-party pricing service when we believe, as the result of our review, that the adjusted price most appropriately reflects the fair value of the particular security.

Following are descriptions of the valuation methodologies and key inputs used to measure financial assets and liabilities recorded at fair value. The descriptions include an indication of the level of the fair value hierarchy in which the assets or liabilities are classified.

Financial Instruments Owned and Available-For-Sale Securities

When available, the fair value of financial instruments is based on quoted prices in active markets and reported in Level 1. Level 1 financial instruments include highly liquid instruments with quoted prices, such as equity securities listed in active markets, U.S. government securities, U.S. government agency securities, corporate equity securities, and fixed income securities.

If quoted prices are not available for identical instruments, fair values are obtained from pricing services, broker quotes, or other model-based valuation techniques with observable inputs, such as the present value of estimated cash flows, and reported as Level 2. The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, instruments whose fair value has been derived using a model where inputs to the model 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 2 financial instruments include U.S. government agency securities, mortgage-backed securities, securities infrequently traded, including corporate fixed income securities, sovereign debt, and equity securities, state and municipal securities, and asset-backed securities, which primarily includes collateralized loan obligations.

We have identified Level 3 financial instruments to include certain asset-backed and non-agency mortgage-backed securities. Level 3 financial instruments have little to no pricing observability as of the report date. These financial instruments do not have active two-way markets and 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.

Investments

Investments carried at fair value primarily include corporate equity securities, auction-rate securities (“ARS”), and private company investments.

Corporate equity securities that are valued based on quoted prices in active markets are reported in Level 1.

ARS are valued based upon our expectations of issuer redemptions and using internal discounted cash flow models that utilize unobservable inputs. ARS are reported as Level 3 assets.

Direct investments in private companies may be valued using the market approach and were valued based on an assessment of each underlying investment, incorporating evaluation of additional significant third-party financing, changes in valuations of comparable peer companies, the business environment of the companies, market indices, assumptions relating to appropriate risk adjustments for nonperformance, and legal restrictions on disposition, among other factors. The fair value derived from the methods used are evaluated and weighted, as appropriate, considering the reasonableness of the range of values indicated. Under the market approach, fair value may be determined by reference to multiples of market-comparable companies or transactions, including earnings before interest, taxes, depreciation, and amortization (“EBITDA”) multiples. For securities utilizing the market comparable companies valuation technique, a significant increase (decrease) in the EBITDA multiple in isolation could result in a significantly higher (lower) fair value measurement.

93

Investments in Funds That Are Measured at Net Asset Value Per Share

Investments at fair value include investments in funds, including certain money market funds that are measured at net asset value (“NAV”). The Company uses NAV to measure the fair value of its fund investments when (i) the fund investment does not have a readily determinable fair value and (ii) the NAV of the investment fund is calculated in a manner consistent with the measurement principles of investment company accounting, including measurement of the underlying investments at fair value.

The Company’s investments in funds measured at NAV include private company investments, partnership interests, mutual funds, private equity funds, and money market funds. Private equity funds primarily invest in a broad range of industries worldwide in a variety of situations, including leveraged buyouts, recapitalizations, growth investments, and distressed investments. The private equity funds are primarily closed-end funds in which the Company’s investments are generally not eligible for redemption. Distributions will be received from these funds as the underlying assets are liquidated or distributed.

The general and limited partnership interests in investment partnerships were primarily valued based upon NAVs received from third-party fund managers. The various partnerships are investment companies, which record their underlying investments at fair value based on fair value policies established by management of the underlying fund. Fair value policies at the underlying fund generally require the funds to utilize pricing/valuation information, including independent appraisals, from third-party sources. However, in some instances, current valuation information for illiquid securities or securities in markets that are not active may not be available from any third-party source or fund management may conclude that the valuations that are available from third-party sources are not reliable. In these instances, fund management may perform model-based analytical valuations that may be used as an input to value these investments.

The tables below present the fair value of our investments in, and unfunded commitments to, funds that are measured at NAV (in thousands):

	December 31, 2018				December 31, 2017

Total	$	36,278	$	2,504	$	101,990	$	3,155

Financial Instruments Sold, But Not Yet Purchased

Financial instruments sold, but not purchased, recorded at fair value based on quoted prices in active markets and other observable market data include highly liquid instruments with quoted prices, such as U.S. government securities, equity securities, and fixed income securities listed in active markets, which are reported as Level 1.

If quoted prices are not available, fair values are obtained from pricing services, broker quotes, or other model-based valuation techniques with observable inputs, such as the present value of estimated cash flows, and reported as Level 2. The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, instruments whose fair value has been derived using a model where inputs to the model 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 2 financial instruments include U.S. government agency securities, mortgage-backed securities not actively traded, corporate securities, including fixed income securities and equity securities, and sovereign debt.

Derivatives

Derivatives are valued using quoted market prices for identical instruments when available or pricing models based on the net present value of estimated future cash flows. The valuation models used require market observable inputs, including contractual terms, market prices, yield curves, credit curves, and measures of volatility. We manage credit risk for our derivative positions on a counterparty-by-counterparty basis and calculate credit valuation adjustments, included in the fair value of these instruments, on the basis of our relationships at the counterparty portfolio/master netting agreement level. These credit valuation adjustments are determined by applying a credit spread for the counterparty to the total expected exposure of the derivative after considering collateral and other master netting arrangements. We have classified our interest rate swaps as Level 2.

The results included in the table above are only a component of the overall investment strategies of our company. The table above does not present Level 1 or Level 2 valued assets or liabilities. The changes to our company’s Level 3 classified instruments during the year ended December 31, 2018 were principally a result of the redemption of ARS. The changes in unrealized gains/(losses) recorded in earnings for the year ended December 31, 2018, relating to Level 3 assets still held at December 31, 2018, were immaterial.

The following table summarizes quantitative information related to the significant unobservable inputs utilized in our company’s Level 3 recurring fair value measurements as of December 31, 2018.

	Valuation technique	Unobservable input	Range	Weighted average
Investments:
Auction rate securities:
Equity securities	Discounted cash flow	Discount rate	0.0% - 5.6%	3.2%
		Workout period	2-3 years	2.4 years
Municipal securities	Discounted cash flow	Discount rate	0.7% - 8.3%	2.8%
		Workout period	1-4 years	2.0 years

The fair value of certain Level 3 assets was determined using various methodologies, as appropriate, including third-party pricing vendors and broker quotes. These inputs are evaluated for reasonableness through various procedures, including due diligence reviews of third-party pricing vendors, variance analyses, consideration of current market environment, and other analytical procedures.

The fair value for our auction rate securities was determined using an income approach based on an internally developed discounted cash flow model. The discounted cash flow model utilizes two significant unobservable inputs: discount rate and workout period. The discount rate was calculated using credit spreads of the underlying collateral or similar securities. The workout period was based on an assessment of publicly available information on efforts to re-establish functioning markets for these securities and our company’s own redemption experience. Significant increases in any of these inputs in isolation would result in a significantly lower fair value. On an ongoing basis, management verifies the fair value by reviewing the appropriateness of the discounted cash flow model and its significant inputs.

Transfers Within the Fair Value Hierarchy

We assess our financial instruments on a quarterly basis to determine the appropriate classification within the fair value hierarchy. Transfers between fair value classifications occur when there are changes in pricing observability levels. Transfers of financial instruments among the levels are deemed to occur at the beginning of the reporting period.

There were $0.9 million of transfers of financial assets from Level 2 to Level 1 during the year ended December 31, 2018, corporate fixed income securities for which market trades were observed that provided transparency into the valuation of these assets. There were $0.8 million of transfers of financial assets from Level 1 to Level 2 during the year ended December 31, 2018, primarily related to corporate fixed income securities for which there were low volumes of recent trade activity observed. There were no transfers of financial assets into or out of Level 3 during the year ended December 31, 2018.

The following, as supplemented by the discussion above, describes the valuation techniques used in estimating the fair value of our financial instruments as of December 31, 2018 and 2017.

Financial Assets

Securities Purchased Under Agreements to Resell

Securities purchased under agreements to resell are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. The carrying values at December 31, 2018 and 2017 approximate fair value due to their short-term nature.

Held-to-Maturity Securities

Securities held to maturity are recorded at amortized cost based on our company’s positive intent and ability to hold these securities to maturity. Securities held to maturity include agency, commercial, and non-agency mortgage-backed securities, asset-backed securities, consisting of collateralized loan obligation securities and Student Loan ARS, and corporate fixed income securities. The estimated fair value, included in the above table, is determined using several factors; however, primary weight is given to discounted cash flow modeling techniques that incorporated an estimated discount rate based upon recent observable debt security issuances with similar characteristics.

Loans Held for Sale

Loans held for sale consist of fixed-rate and adjustable-rate residential real estate loans intended for sale. Loans held for sale are stated at lower of cost or fair value. Fair value is determined based on prevailing market prices for loans with similar characteristics or on sale contract prices.

Bank Loans

The fair values of mortgage loans and commercial loans were estimated using a discounted cash flow method, a form of the income approach. Discount rates were determined considering rates at which similar portfolios of loans would be made under current conditions and considering liquidity spreads applicable to each loan portfolio based on the secondary market.

Financial Liabilities

Securities Sold Under Agreements to Repurchase

Securities sold under agreements to repurchase are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. The carrying values at December 31, 2018 and 2017 approximate fair value due to the short-term nature.

Bank Deposits

The fair value for demand deposits is equal to the amount payable on demand at the reporting date (that is, their carrying amounts). The carrying amounts of variable-rate money-market and savings accounts approximate their fair values at the reporting date as these are short-term in nature. The fair value of other interest-bearing deposits, including certificates of deposit, was calculated by discounting the future cash flows using discount rates based on the expected current market rates for similar products with similar remaining terms.

Borrowings

The carrying amount of borrowings approximates fair value due to the relative short-term nature of such borrowings. In addition, Stifel Bancorp’s Federal Home Loan Bank advances reflect terms that approximate current market rates for similar borrowings.

100

Senior Notes

The fair value of our senior notes is estimated based upon quoted market prices.

Debentures to Stifel Financial Capital Trusts

The fair value of our trust preferred securities is based on the discounted value of contractual cash flows. We have assumed a discount rate based on similar type debt instruments.

These fair value disclosures represent our best estimates based on relevant market information and information about the financial instruments. Fair value estimates are based on judgments regarding future expected losses, current economic conditions, risk characteristics of the various instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in the above methodologies and assumptions could significantly affect the estimates.

At December 31, 2018 and 2017, financial instruments owned in the amount of $669.0 million and $810.3 million, respectively, were pledged as collateral (on a settlement-date basis) for our repurchase agreements and short-term borrowings. Our financial instruments owned are presented on a trade-date basis in the consolidated statements of financial condition.

Financial instruments sold, but not yet purchased, represent obligations of our company to deliver the specified security at the contracted price, thereby creating a liability to purchase the security in the market at prevailing prices in future periods. We are obligated to acquire the securities sold short at prevailing market prices in future periods, which may exceed the amount reflected in the consolidated statements of financial condition.

At December 31, 2018, the amortized cost of 258 securities classified as available for sale exceeded their fair value by $55.9 million, of which $33.9 million related to investment securities that had been in a loss position for 12 months or longer. The total fair value of these investments at December 31, 2018, was $2.6 billion, which was 85.5% of our available-for-sale portfolio.

At December 31, 2018, the carrying value of 196 securities held to maturity exceeded their fair value by $102.0 million, of which $30.2 million related to securities held to maturity that have been in a loss position for 12 months or longer. As discussed in more detail below, we conduct periodic reviews of all securities with unrealized losses to assess whether the impairment is other-than-temporary.

Other-Than-Temporary Impairment

We evaluate all securities in an unrealized loss position quarterly to assess whether the impairment is other-than-temporary. Our OTTI assessment is a subjective process requiring the use of judgments and assumptions. There was no credit-related OTTI recognized during the years ended December 31, 2018, 2017, and 2016.

We believe the gross unrealized losses of $157.9 million related to our investment portfolio, as of December 31, 2018, are attributable to changes in market interest rates. We, therefore, do not expect to incur any credit losses related to these securities. In addition, we have no intent to sell these securities with unrealized losses, and it is not more likely than not that we will be required to sell these securities prior to recovery of the amortized cost. Accordingly, we have concluded that the impairment on these securities is not other-than-temporary.

In determining the amount of our allowance, we rely on an analysis of our loan portfolio, our experience, and our evaluation of general economic conditions. If our assumptions prove to be incorrect, our current allowance may not be sufficient to cover future loan losses and we may experience significant increases to our provision.

There are two components of the allowance for loan losses: the inherent allowance component and the specific allowance component. The inherent allowance component of the allowance for loan losses is used to estimate the probable losses inherent in the loan portfolio and includes non-homogeneous loans that have not been identified as impaired and portfolios of smaller balance homogeneous loans. Our company maintains methodologies by loan product for calculating an allowance for loan losses that estimates the inherent losses in the loan portfolio. Qualitative and environmental factors, such as economic and business conditions, nature and volume of the portfolio and lending terms, and volume and severity of past due loans may also be considered in the calculations. The allowance for loan losses is maintained at a level reasonable to ensure that it can adequately absorb the estimated probable losses inherent in the portfolio.

The specific allowance component of the allowance for loan losses is used to estimate probable losses for non-homogeneous exposures, including loans modified in a Troubled Debt Restructuring (TDR), which have been specifically identified for impairment analysis by our company and determined to be impaired. At December 31, 2018, we had $24.4 million of impaired loans, net of discounts, which included $9.1 million in troubled debt restructurings. The specific allowance on impaired loans at December 31, 2018 was $8.7 million. At December 31, 2017, we had $29.2 million of impaired loans, net of discounts, which included $9.1 million in troubled debt restructurings. The specific allowance on impaired loans at December 31, 2017 was $9.1 million. The gross interest income related to impaired loans, which would have been recorded had these loans been current in accordance with their original terms, and the interest income recognized on these loans during the year ended December 31, 2018 and 2017, were insignificant to the consolidated financial statements.

Credit quality indicators

As of December 31, 2018, bank loans were primarily extended to non-investment-grade borrowers. Substantially all of these loans align with the U.S. federal bank regulatory agencies’ definition of Pass. Loans meet the definition of Pass when they are performing and/or do not demonstrate adverse characteristics that are likely to result in a credit loss. A loan is determined to be impaired when principal or interest becomes 90 days past due or when collection becomes uncertain. At the time a loan is determined to be impaired, the accrual of interest and amortization of deferred loan origination fees is discontinued (non-accrual status), and any accrued and unpaid interest income is reversed.

We closely monitor economic conditions and loan performance trends to manage and evaluate our exposure to credit risk. Trends in delinquency ratios are an indicator, among other considerations, of credit risk within our loan portfolios. The level of nonperforming assets represents another indicator of the potential for future credit losses. Accordingly, key metrics we track and use in evaluating the credit quality of our loan portfolio include delinquency and nonperforming asset rates, as well as charge-off rates and our internal risk ratings of the loan portfolio. In general, we are a secured lender. At December 31, 2018 and 2017, 98.4% and 97.2% of our loan portfolio was collateralized, respectively. Collateral is required in accordance with the normal credit evaluation process based upon the creditworthiness of the customer and the credit risk associated with the particular transaction. Our company uses the following definitions for risk ratings:

Pass. A credit exposure rated pass has a continued expectation of timely repayment, all obligations of the borrower are current, and the obligor complies with material terms and conditions of the lending agreement.

Special Mention. Extensions of credit that have potential weakness that deserve management’s close attention and, if left uncorrected, may, at some future date, result in the deterioration of the repayment prospects or collateral position.

Substandard. Obligor has a well-defined weakness that jeopardizes the repayment of the debt and has a high probability of payment default with the distinct possibility that we will sustain some loss if noted deficiencies are not corrected.

Doubtful. Inherent weakness in the exposure makes the collection or repayment in full, based on existing facts, conditions, and circumstances, highly improbable, and the amount of loss is uncertain.

Doubtful loans are considered impaired. Substandard loans are regularly reviewed for impairment. When a loan is impaired, the impairment is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, or as a practical expedient, the observable market price of the loan or the fair value of the collateral if the loan is collateral dependent.

Portfolio segments:

Real Estate. Real estate loans include commercial real estate, residential real estate non-conforming loans, residential real estate conforming loans and home equity lines of credit. The allowance methodology related to real estate loans considers several factors, including, but not limited to, loan-to-value ratio, FICO score, home price index, delinquency status, credit limits, and utilization rates.

108

Commercial and industrial (“C&I”). C&I loans primarily include commercial and industrial lending used for general corporate purposes, working capital and liquidity, and “event-driven." “Event-driven” loans support client merger, acquisition or recapitalization activities. C&I lending is structured as revolving lines of credit, letter of credit facilities, term loans and bridge loans. Risk factors considered in determining the allowance for corporate loans include the borrower’s financial strength, seniority of the loan, collateral type, leverage, volatility of collateral value, debt cushion, and covenants.

Securities-based loans. Securities-based loans allow clients to borrow money against the value of qualifying securities for any suitable purpose other than purchasing, trading, or carrying securities or refinancing margin debt. The majority of consumer loans are structured as revolving lines of credit and letter of credit facilities and are primarily offered through Stifel’s Pledged Asset ("SPA") program. The allowance methodology for securities-based lending considers the collateral type underlying the loan, including the liquidity and trading volume of the collateral, position concentration and other borrower specific factors such as personal guarantees.

Construction and land. Short-term loans used to finance the development of a real estate project.

Other. Other loans includes consumer, credit card, and indirect lending.

On March 19, 2018, the Company completed the acquisition of Ziegler. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $19.0 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management and Institutional Group segments. Identifiable intangible assets purchased by our company consisted of customer relationships and non-compete agreements with an acquisition-date fair value of $9.5 million. See Note 3 in the notes to our consolidated financial statements for additional information regarding the acquisition of Ziegler.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the Ziegler business and of the hired financial advisors and the conversion of the customer accounts to our platform. Goodwill is expected to be deductible for federal income tax purposes.

On August 31, 2018, the Company completed the acquisition of BBI. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $38.4 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management segment. Identifiable intangible assets purchased by our company consisted of core deposits with an acquisition-date fair value of $8.6 million. The allocation of the purchase price of BBI is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets of BBI as of the acquisition date and the identified intangible assets. The final goodwill recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments and the recording of identified intangible assets. See Note 3 in the notes to our consolidated financial statements for additional information regarding the acquisition of BBI.

On October 1, 2018, the Company completed the acquisition of Rand. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $8.3 million of goodwill in the consolidated statement of financial condition, which has been

110

allocated to our company’s Global Wealth Management segment. Identifiable intangible assets purchased by our company consisted of customer relationships with an acquisition-date fair value of $4.6 million. The allocation of the purchase price of Rand is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets of Rand as of the acquisition date and the identified intangible assets. The final goodwill recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments and the recording of identified intangible assets. See Note 3 in the notes to our consolidated financial statements for additional information regarding the acquisition of Rand.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the Rand business and of the hired financial advisors and the conversion of the customer accounts to our platform. Goodwill is expected to be deductible for federal income tax purposes.

Amortizable intangible assets consist of acquired customer relationships, trade name, core deposits investment banking backlog, and non-compete agreements that are amortized over their contractual or determined useful lives.

NOTE 11 – Borrowings and Federal Home Loan Bank Advances

Our short-term financing is generally obtained through short-term bank line financing on an uncommitted, secured basis, advances from the Federal Home Loan Bank, and securities lending arrangements. We borrow from various banks on a demand basis with company-owned and customer securities pledged as collateral. The value of customer-owned securities used as collateral is not reflected in the consolidated statements of financial condition. We also have an unsecured, committed bank line available.

Our uncommitted secured lines of credit at December 31, 2018, totaled $1.0 billion with six banks and are dependent on having appropriate collateral, as determined by the bank agreements, to secure an advance under the line. The availability of our uncommitted lines is subject to approval by the individual banks each time an advance is requested and may be denied. Our peak daily borrowing on our uncommitted secured lines was $391.0 million during the year ended December 31, 2018. There are no compensating balance requirements under these arrangements. Any borrowings on secured lines of credit are generally utilized to finance certain fixed income securities. At December 31, 2018, our uncommitted secured lines of credit of $56.0 million are included in borrowings in the consolidated statements of financial condition. Our uncommitted secured lines were collateralized by company-owned securities valued at $63.0 million at December 31, 2018.

111

The Federal Home Loan advances of $540.0 million as of December 31, 2018, are floating-rate advances. The weighted average interest rates on these advances during the year ended December 31, 2018, was 1.61%. The advances are secured by Stifel Bancorp’s residential mortgage loan portfolio and investment portfolio. The interest rates reset on a daily basis. Stifel Bancorp has the option to prepay these advances without penalty on the interest reset date.

Our committed bank line financing at December 31, 2018, consisted of a $200.0 million revolving credit facility. The credit facility expires in March 2020. The applicable interest rate under the revolving credit facility is calculated as a per annum rate equal to the London Interbank Offered Rate (“LIBOR”) plus 2.00%, as defined in the revolving credit facility. At December 31, 2018, we had no advances on our revolving credit facility and were in compliance with all covenants.

In June 2018, Stifel, our broker-dealer subsidiary, entered into a 364-day Credit Agreement (“Stifel Credit Facility”) with a maturity date of June 2019 in which the lenders are a number of financial institutions. This committed unsecured borrowing facility provides for maximum borrowings of up to $250.0 million at variable rates of interest. At December 31, 2018, we had no advances on the Stifel Credit Facility and were in compliance with all covenants.

As of December 31, 2018, a subsidiary of Stifel Bancorp was a party to two Notes. The Notes mature in 2043. The Notes bear interest contractually at fixed rates as per the Note Purchase Agreement. The outstanding balance on the Notes at December 31, 2018 was $124.5 million and is included in borrowings in the consolidated statements of financial condition.

NOTE 14 – Derivative Instruments and Hedging Activities

We use interest rate swaps as part of our interest rate risk management strategy. Interest rate swaps generally involve the exchange of fixed and variable rate interest payments between two parties, based on a common notional principal amount and maturity date with no exchange of underlying principal amounts. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for our company making fixed payments. Our policy is not to offset fair value amounts recognized for derivative instruments and fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral arising from derivative instruments recognized at fair value executed with the same counterparty under master netting arrangements.

Cash Flow Hedges

We have entered into interest rate swap agreements that effectively modify our exposure to interest rate risk by converting floating rate debt to a fixed rate debt. The swaps have an average remaining life of 1.1 years.

Any unrealized gains or losses related to cash flow hedging instruments are reclassified from accumulated other comprehensive loss into earnings in the same period the hedged forecasted transaction affects earnings and are recorded in interest expense in the consolidated statements of operations. The ineffective portion of the cash flow hedging instruments is recorded in other income or other operating expense in the consolidated statements of operations.

Amounts reported in accumulated other comprehensive loss related to derivatives will be reclassified to interest expense as interest payments are made on our variable rate deposits. During the next twelve months, we estimate that $3.9 million will be reclassified as an increase to interest expense.

The following table shows the effect of our company’s derivative instruments in the consolidated statements of operations for the years ended December 31, 2018, 2017, and 2016 (in thousands):

Cash flow interest rate contracts	$	6,383	Interest expense	$	(5,444	)	Interest expense	$	30

We maintain a risk management strategy that incorporates the use of derivative instruments to minimize significant unplanned fluctuations in earnings caused by interest rate volatility. Our goal is to manage sensitivity to changes in rates by hedging the maturity

114

characteristics of variable rate affiliated deposits, thereby limiting the impact on earnings. By using derivative instruments, we are exposed to credit and market risk on those derivative positions. We manage the market risk associated with interest rate contracts by establishing and monitoring limits as to the types and degree of risk that may be undertaken. Credit risk is equal to the extent of the fair value gain in a derivative if the counterparty fails to perform. When the fair value of a derivative contract is positive, this generally indicates that the counterparty owes our company and, therefore, creates a repayment risk for our company. When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, have no repayment risk. See Note 5 in the notes to our consolidated financial statements for further discussion on how we determine the fair value of our financial instruments. We minimize the credit (or repayment) risk in derivative instruments by entering into transactions with high-quality counterparties that are reviewed periodically by senior management.

Credit Risk-Related Contingency Features

We have agreements with our derivative counterparties containing provisions where if we default on any of our indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then we could also be declared in default on our derivative obligations.

We have agreements with certain of our derivative counterparties that contain provisions where if our shareholders’ equity declines below a specified threshold or if we fail to maintain a specified minimum shareholders’ equity, then we could be declared in default on our derivative obligations.

Certain of our agreements with our derivative counterparties contain provisions where if a specified event or condition occurs that materially changes our creditworthiness in an adverse manner, we may be required to fully collateralize our obligations under the derivative instrument.

Regulatory Capital-Related Contingency Features

Certain of our derivative instruments contain provisions that require us to maintain our capital adequacy requirements. If we were to lose our status as “adequately capitalized,” we would be in violation of those provisions, and the counterparties of the derivative instruments could request immediate payment or demand immediate and ongoing full overnight collateralization on derivative instruments in net liability positions.

Counterparty Risk

In the event of counterparty default, our economic loss may be higher than the uncollateralized exposure of our derivatives if we were not able to replace the defaulted derivatives in a timely fashion. We monitor the risk that our uncollateralized exposure to each of our counterparties for interest rate swaps will increase under certain adverse market conditions by performing periodic market stress tests. These tests evaluate the potential additional uncollateralized exposure we would have to each of these derivative counterparties assuming changes in the level of market rates over a brief time period.

NOTE 17 – Commitments, Guarantees, and Contingencies

Broker-Dealer Commitments and Guarantees

In the normal course of business, we enter into underwriting commitments. Settlement of transactions relating to such underwriting commitments, which were open at December 31, 2018, had no material effect on the consolidated financial statements.

We also provide guarantees to securities clearinghouses and exchanges under their standard membership agreement, which requires members to guarantee the performance of other members. Under the agreement, if another member becomes unable to satisfy its obligations to the clearinghouse, other members would be required to meet shortfalls. Our liability under these agreements is not quantifiable and may exceed the cash and securities we have posted as collateral. However, the potential requirement for us to make payments under these arrangements is considered remote. Accordingly, no liability has been recognized for these arrangements.

Other Commitments

In the ordinary course of business, Stifel Bancorp has commitments to extend credit in the form of commitments to originate loans, standby letters of credit, and lines of credit. See Note 23 in the notes to consolidated financial statements for further details.

We have committed capital to certain entities, and these commitments generally have no specified call dates. We had $2.5 million of commitments outstanding at December 31, 2018.

Concentration of Credit Risk

We provide investment, capital-raising, and related services to a diverse group of domestic customers, including governments, corporations, and institutional and individual investors. Our exposure to credit risk associated with the non-performance of customers in fulfilling their contractual obligations pursuant to securities transactions can be directly impacted by volatile securities markets, credit markets, and regulatory changes. This exposure is measured on an individual customer basis and on a group basis for customers that share similar attributes. To reduce the potential for risk concentrations, counterparty credit limits have been implemented for certain products and are continually monitored in light of changing customer and market conditions. As of December 31, 2018 and 2017, we did not have significant concentrations of credit risk with any one customer or counterparty, or any group of customers or counterparties.

117

Operating Leases

Future minimum commitments under non-cancelable operating leases at December 31, 2018, are as follows (in thousands):

2019	$	89,887
2020		81,899
2021		66,887
2022		59,353
2023		50,916
Thereafter		107,678
	$	456,620

Certain leases contain provisions for renewal options and escalation clauses based on increases in certain costs incurred by the lessor. We amortize office lease incentives and rent escalation on a straight-line basis over the life of the lease. Rent expense for the years ended December 31, 2018, 2017, and 2016, included in occupancy and equipment rental in the consolidated statements of operations, was $104.6 million, $104.5 million, and $108.7 million, net of sublease income.

NOTE 18 – Legal Proceedings

Our company and its subsidiaries are named in and subject to various proceedings and claims arising primarily from our securities business activities, including lawsuits, arbitration claims, class actions, and regulatory matters. Some of these claims seek substantial compensatory, punitive, or indeterminate damages. Our company and its subsidiaries are also involved in other reviews, investigations, and proceedings by governmental and self-regulatory organizations regarding our business, which may result in adverse judgments, settlements, fines, penalties, injunctions, and other relief. We are contesting allegations in these claims, and we believe that there are meritorious defenses in each of these lawsuits, arbitrations, and regulatory investigations. In view of the number and diversity of claims against our company, the number of jurisdictions in which litigation is pending, and the inherent difficulty of predicting the outcome of litigation and other claims, we cannot state with certainty what the eventual outcome of pending litigation or other claims will be.

We have established reserves for potential losses that are probable and reasonably estimable that may result from pending and potential legal actions, investigations, and regulatory proceedings. In many cases, however, it is inherently difficult to determine whether any loss is probable or reasonably possible or to estimate the amount or range of any potential loss, particularly where proceedings may be in relatively early stages or where plaintiffs are seeking substantial or indeterminate damages. Matters frequently need to be more developed before a loss or range of loss can reasonably be estimated.

In our opinion, based on currently available information, review with outside legal counsel, and consideration of amounts provided for in our consolidated financial statements with respect to these matters the ultimate resolution of these matters will not have a material adverse impact on our financial position and results of operations. However, resolution of one or more of these matters may have a material effect on the results of operations in any future period, depending upon the ultimate resolution of those matters and depending upon the level of income for such period. For matters where a reserve has not been established and for which we believe a loss is reasonably possible, as well as for matters where a reserve has been recorded but for which an exposure to loss in excess of the amount accrued is reasonably possible, based on currently available information, we believe that such losses will not have a material effect on our consolidated financial statements.

NOTE 19 – Regulatory Capital Requirements

We operate in a highly regulated environment and are subject to capital requirements, which may limit distributions to our company from its subsidiaries. Distributions from our broker-dealer subsidiaries are subject to net capital rules. A broker-dealer that fails to comply with the SEC’s Uniform Net Capital Rule (Rule 15c3-1) may be subject to disciplinary actions by the SEC and self-regulatory organizations, such as FINRA, including censures, fines, suspension, or expulsion. Stifel has chosen to calculate its net capital under the alternative method, which prescribes that their net capital shall not be less than the greater of $1.0 million or two percent of aggregate debit balances (primarily receivables from customers) computed in accordance with the SEC’s Customer Protection Rule (Rule 15c3-3). Our other broker-dealer subsidiaries calculate their net capital under the aggregate indebtedness method, whereby their aggregate indebtedness may not be greater than fifteen times their net capital (as defined).

At December 31, 2018, Stifel had net capital of $342.7 million, which was 20.9% of aggregate debit items and $310.0 million in excess of its minimum required net capital. At December 31, 2018, all of our other broker-dealer subsidiaries’ net capital exceeded the minimum net capital required under the SEC rule.

Our international subsidiary is subject to the regulatory supervision and requirements of the Financial Conduct Authority (“FCA”) in the United Kingdom. At December 31, 2018, our international subsidiary’s capital and reserves were in excess of the financial resources requirement under the rules of the FCA.

118

Our company, as a bank holding company, Stifel Bank & Trust, and Stifel Bank (“bank subsidiaries”) are subject to various regulatory capital requirements administered by the Federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our company’s and its bank subsidiaries’ financial results. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, our company and its bank subsidiaries must meet specific capital guidelines that involve quantitative measures of our assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. Our company’s and its bank subsidiaries’ capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Under the Basel III rules, the quantity and quality of regulatory capital increases, a capital conservation buffer was established, selected changes were made to the calculation of risk-weighted assets, and a new ratio, common equity Tier 1 was introduced, all of which are applicable to both our company and its bank subsidiaries’. Various aspects of Basel III will be subject to multi-year transition periods through December 31, 2018.

Our company and its bank subsidiaries are required to maintain minimum amounts and ratios of Total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), Tier 1 capital to average assets (as defined), and under rules defined in Basel III, Common equity Tier 1 capital to risk-weighted assets. Our company and its bank subsidiaries each calculate these ratios in order to assess compliance with both regulatory requirements and their internal capital policies. At current capital levels, our company and its bank subsidiaries are each categorized as “well capitalized” under the regulatory framework for prompt corrective action.

To be categorized as “well capitalized,” our company and its bank subsidiaries must maintain total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the tables below (in thousands, except ratios).

NOTE 20 – Revenues from Contracts with Customers

The following table presents the Company’s total revenues separated between revenues from contracts with customers and other sources of revenues for the year ended December 31, 2018 (in thousands):

	Year Ended December 31, 2018
Revenues from contracts with customers:
Commissions	$	657,732
Investment banking		707,670
Asset management and service fees		806,175
Other		15,568
Total revenue from contracts with customers		2,187,145
Other sources of revenue:
Interest		646,449
Principal transactions		351,378
Other		9,985
Total revenues	$	3,194,957

Revenue from contracts with customers is recognized when, or as, we satisfy our performance obligations by transferring the promised goods or services to the customers. A good or service is transferred to a customer when, or as, the customer obtains control of that good or service. A performance obligation may be satisfied over time or at a point in time. Revenue from a performance obligation satisfied over time is recognized by measuring our progress in satisfying the performance obligation in a manner that depicts the transfer of the goods or services to the customer. Revenue from a performance obligation satisfied at a point in time is recognized at the point in time that we determine the customer obtains control over the promised good or service. The amount of revenue recognized reflects the consideration we expect to be entitled to in exchange for those promised goods or services (i.e., the “transaction price”). In determining the transaction price, we consider multiple factors, including the effects of variable consideration. Variable consideration is included in the transaction price only to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainties with respect to the amount are resolved. In determining when to include variable consideration in the transaction price, we consider the range of possible outcomes, the predictive value of our past experiences, the time period of when uncertainties expect to be resolved and the amount of consideration that is susceptible to factors outside of our influence, such as market volatility or the judgment and actions of third parties.

The following provides detailed information on the recognition of our revenues from contracts with customers:

Commissions. We earn commission revenue by executing, settling, and clearing transactions for clients primarily in OTC and listed equity securities, insurance products, and options. Trade execution and clearing and custody services, when provided together, represent a single performance obligation as the services are not separately identifiable in the context of the contract. Commission revenues associated with combined trade execution and clearing and custody services, as well as trade execution services on a standalone basis, are recognized at a point in time on trade-date. Commission revenues are generally paid on settlement date and we record a receivable between trade-date and payment on settlement date.

Investment Banking. We provide our clients with a full range of capital markets and financial advisory services. Capital markets services include underwriting and placement agent services in both the equity and debt capital markets, including private equity placements, initial public offerings, follow-on offerings, underwriting and distributing public and private debt.

Capital raising revenues are recognized at a point in time on trade-date, as the client obtains the control and benefit of the capital markets offering at that point. Costs associated with capital raising transactions are deferred until the related revenue is recognized or the engagement is otherwise concluded, and are recorded on a gross basis within other operating expenses in the consolidated statements of operations as we are acting as a principal in the arrangement. Any expenses reimbursed by our clients are recognized as investment banking revenues.

Revenues from financial advisory services primarily consist of fees generated in connection with merger, acquisition and restructuring transactions. 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. Fees received prior to the completion of the transaction are deferred within accounts payable and accrued expenses on the consolidated statements of financial condition. Advisory fees from restructuring engagements are recognized over time using a time elapsed measure of progress as our clients simultaneously receive and consume the benefits of those services as they are provided. A significant portion of the fees we receive for our advisory services are considered variable as they are contingent upon a future event (e.g., completion of a transaction or third party emergence from bankruptcy) and are excluded from the transaction price until the uncertainty associated with the variable consideration is subsequently resolved, which is expected to occur upon achievement of the specified milestone. Payment for advisory services are generally due promptly upon completion of a specified milestone or, for retainer fees, periodically over the course of the engagement. We recognize a receivable between the date of completion of the milestone and payment by the customer. Expenses

associated with investment banking advisory engagements are deferred only to the extent they are explicitly reimbursable by the client and the related revenue is recognized upon completion of services. All other investment banking advisory related expenses, including expenses incurred related to restructuring assignments, are expensed as incurred. All investment banking advisory expenses are recognized within other operating expenses in the consolidated statements of operations and any expenses reimbursed by our clients are recognized as investment banking revenues.

Asset Management Fees. We earn management and performance fees in connection with investment advisory services provided to institutional and individual clients. Investment advisory fees are charged based on the value of assets in fee-based accounts and are affected by changes in the balances of client assets due to market fluctuations and levels of net new client assets. Fees are charged either in advance based on fixed rates applied to the value of the customers’ account at the beginning of the period or periodically based on contracted rates and account performance. Contracts can be terminated at any time with no incremental payments due to our company upon termination. If the contract is terminated by the customer fees are prorated for the period and fees charged for the post termination period are refundable to the customer.

Disaggregation of Revenue

The following tables present the Company’s revenues from contracts with customers by reportable segment disaggregated by major business activity and primary geographic regions for the year ended December 31, 2018 (in thousands):

Information on Remaining Performance Obligations and Revenue Recognized from Past Performance

We do not disclose information about remaining performance obligations pertaining to contracts that have an original expected duration of one year or less. The transaction price allocated to remaining unsatisfied or partially unsatisfied performance obligations with an original expected duration exceeding one year was not material at December 31, 2018. Investment banking advisory fees that are contingent upon completion of a specific milestone and fees associated with certain distribution services are also excluded as the fees are considered variable and not included in the transaction price at December 31, 2018.

Contract Balances

The timing of our revenue recognition may differ from the timing of payment by our customers. We record a receivable when revenue is recognized prior to payment and we have an unconditional right to payment. Alternatively, when payment precedes the provision of the related services, we record deferred revenue until the performance obligations are satisfied.

We had receivables related to revenues from contracts with customers of $116.7 million and $93.0 million at December 31, 2018 and December 31, 2017, respectively, in other assets in the consolidated statements of financial condition. We had no significant impairments related to these receivables during the year ended December 31, 2018.

Our deferred revenue primarily relates to retainer fees received in investment banking advisory engagements where the performance obligation has not yet been satisfied. Deferred revenue at December 31, 2018 was $9.5 million and included in accounts payable and accrued expenses in the consolidated statements of financial condition.

NOTE 22 – Employee Incentive, Deferred Compensation, and Retirement Plans

We maintain several incentive stock award plans that provide for the granting of stock options, stock appreciation rights, restricted stock, performance award, stock units, and debentures to our employees. We are permitted to issue new shares under all stock award plans approved by shareholders or to reissue our treasury shares. Awards under our company’s incentive stock award plans are granted at market value at the date of grant. The awards generally vest ratably over a one- to ten-year vesting period.

All stock-based compensation plans are administered by the Compensation Committee of the Board of Directors (“Compensation Committee”), which has the authority to interpret the plans, determine to whom awards may be granted under the plans, and determine the terms of each award. According to these plans, we are authorized to grant an additional 5.2 million shares at December 31, 2018.

Stock-based compensation expense included in compensation and benefits in the consolidated statements of operations for our company’s incentive stock award plans was $111.8 million, $246.7 million, and $190.1 million for the years ended December 31, 2018, 2017, and 2016, respectively.

The tax benefit related to stock-based compensation recognized in shareholders’ equity was $4.0 million for the year ended December 31, 2018. As a result of the adoption of a new accounting standard on January 1, 2017, we recognized an excess tax benefit from stock-based compensation of $64.7 million for the year ended December 31, 2017. We adopted the new guidance prospectively. The tax provision related to stock-based compensation recognized in shareholders’ equity was $4.9 million for the year ended December 31, 2016.

In response to the Tax Legislation that was enacted in December 2017, the Company offered certain employees the opportunity to participate in the conversion of certain restricted stock units into restricted stock pursuant to a Modification Award Agreement. Under the terms of the Modification Award Agreement, vesting of certain restricted stock will no longer be contingent upon continued employment but rather will vest so long as the employee is not engaged in certain competitive or soliciting activities as provided in the Wealth Accumulation Plan (the “Plan”). The conversion through acceptance of the Modification Agreement by the participating employees resulted in a charge of $55.9 million, which is included in compensation and benefits in the consolidated statement of operations for the year ended December 31, 2017.  The fair value of these awards was based upon the closing price of our company’s common stock on the date of the grant of the awards.

In December 2017, the Company accelerated the vesting of certain outstanding debenture awards, resulting in a charge of $51.4 million, which is included in compensation and benefits in the consolidated statement of operations for the year ended December 31, 2017.

During 2016, the Company’s Board of Directors removed the continuing service requirements associated with restricted stock units that were granted to certain employees of Barclays in December 2015. As a result of the modification, the awards were expensed at date of modification, resulting in a charge of $58.6 million during 2016. The fair value of the awards is based upon the closing price of our company’s common stock on the date of the grant of the awards. These charges are included in compensation and benefits in the consolidated statements of operations for the year ended December 31, 2016.

122

Stock Options

We have substantially eliminated the use of stock options as a form of compensation. During the year ended December 31, 2018, no options were granted.

The total intrinsic value of options exercised during the years ended December 31, 2018, 2017 and 2016 were not material. Cash proceeds from the exercise of stock options were not material for the years ended December 31, 2018, 2017, and 2016.

Restricted Stock Units and Restricted Stock Awards

A restricted stock unit represents the right to receive a share of common stock from our company at a designated time in the future without cash payment by the employee and is issued in lieu of cash incentive, principally for deferred compensation and employee retention plans. The restricted stock units vest on an annual basis over the next one to ten years and are distributable, if vested, at future specified dates. Restricted stock awards are restricted as to sale or disposition. These restrictions lapse over the next one to five years.

Our company grants Performance-based Restricted Stock Units (“PRSUs”) to its executive officers. Under the terms of the grants, the number of PRSUs that will vest and convert to shares will be based on our company's achievement of the pre-determined performance objectives during the performance period. The PRSUs will be measured over a four-year performance period and vested over a five-year period. The number of shares converted has the potential to range from 0% to 200% based on how our company performs during the performance period. Compensation expense is amortized on a straight-line basis over the service period based on the fair value of the award on the grant date. The Company’s pre-determined performance objectives must be met for the awards to vest. Employees forfeit unvested share units upon termination of employment with a corresponding reversal of compensation expense. At December 31, 2018, the total number of restricted stock units and restricted stock awards outstanding was 16.4 million, of which 14.1 million were unvested. At December 31, 2018, the total number of PRSU’s was 0.7 million, of which all were unvested.

A summary of unvested restricted equity award activity, which includes restricted stock units and restricted stock awards, for the year ended December 31, 2018 is presented below (in thousands, except weighted-average fair value):

	Units			Weighted-average grant date fair value
Unvested December 31, 2017		13,938		$	44.31
Granted		2,496			55.94
Vested		(2,030	)		41.18
Cancelled		(287	)		47.98
Unvested December 31, 2018		14,117		$	46.75

At December 31, 2018, there was approximately $297.4 million of unrecognized compensation cost for restricted stock units and restricted stock, which is expected to be recognized over a weighted-average period of 2.8 years. The fair value of restricted stock units and restricted stock that vested or converted during the year ended December 31, 2018, was $83.6 million.

Deferred Compensation Plans

The Wealth Accumulation Plan (the “Plan”) is provided to certain revenue producers, officers, and key administrative employees, whereby a certain percentage of their incentive compensation is deferred as defined by the Plan into company stock units and debentures. Participants may elect to defer a portion of their incentive compensation. Deferred awards generally vest over a one- to ten-year period and are distributable upon vesting or at future specified dates. Deferred compensation costs are amortized on a straight-line basis over the vesting period. Elective deferrals are 100% vested.

Additionally, the Plan allows Stifel financial advisors who achieve certain levels of production the option to defer a certain percentage of their gross commissions. As stipulated by the Plan, the financial advisors will defer 5% of their gross commissions. The mandatory deferral will be split evenly between company restricted stock units and a company fixed-rate cash debenture. They have the option to defer an additional 1% of gross commissions into company stock units with a 25% matching contribution

In addition, certain financial advisors, upon joining our company, may receive company stock units in lieu of transition cash payments. Deferred compensation related to these awards generally vests over a one- to eight-year period. Deferred compensation costs are amortized on a straight-line basis over the deferral period.

Employee Profit Sharing Plan

Eligible employees of our company who have met certain service requirements may participate in the Stifel Financial Corp. Profit Sharing 401(k) Plan (the “Plan”). Employees are permitted within limitations imposed by tax law to make pre-tax contributions to the Plan. We may match certain employee contributions or make additional contributions to the Plan at our discretion. Our contributions to the Profit Sharing Plan, included in compensation and benefits in the consolidated statements of operations, were $12.8 million, $7.1 million, and $6.5 million for the years ended December 31, 2018, 2017, and 2016, respectively.

123

NOTE 23 – Off-Balance Sheet Credit Risk

In the normal course of business, we execute, settle, and finance customer and proprietary securities transactions. These activities expose our company to off-balance sheet risk in the event that customers or other parties fail to satisfy their obligations.

In accordance with industry practice, securities transactions generally settle within two business days after trade date. Should a customer or broker fail to deliver cash or securities as agreed, we may be required to purchase or sell securities at unfavorable market prices.

We borrow and lend securities to facilitate the settlement process and finance transactions, utilizing customer margin securities held as collateral. We monitor the adequacy of collateral levels on a daily basis. We periodically borrow from banks on a collateralized basis, utilizing firm and customer margin securities in compliance with SEC rules. Should the counterparty fail to return customer securities pledged, we are subject to the risk of acquiring the securities at prevailing market prices in order to satisfy our customer obligations. We control our exposure to credit risk by continually monitoring our counterparties’ positions, and where deemed necessary, we may require a deposit of additional collateral and/or a reduction or diversification of positions. Our company sells securities it does not currently own (short sales) and is obligated to subsequently purchase such securities at prevailing market prices. We are exposed to risk of loss if securities prices increase prior to closing the transactions. We control our exposure to price risk from short sales through daily review and setting position and trading limits.

We manage our risks associated with the aforementioned transactions through position and credit limits and the continuous monitoring of collateral. Additional collateral is required from customers and other counterparties when appropriate.

We have accepted collateral in connection with resale agreements, securities borrowed transactions, and customer margin loans. Under many agreements, we are permitted to sell or repledge these securities held as collateral and use these securities to enter into securities lending arrangements or to deliver to counterparties to cover short positions. At December 31, 2018 and 2017, the fair value of securities accepted as collateral where we are permitted to sell or repledge the securities was $2.4 billion and $2.4 billion, respectively, and the fair value of the collateral that had been sold or repledged was $535.4 million and $233.7 million, respectively.

We enter into interest rate derivative contracts to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Our derivative financial instruments are principally used to manage differences in the amount, timing, and duration of our known or expected cash payments related to certain variable-rate affiliated deposits. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for us making fixed-rate payments. Our interest rate hedging strategies may not work in all market environments and, as a result, may not be effective in mitigating interest rate risk.

Derivatives’ notional contract amounts are not reflected as assets or liabilities in the consolidated statements of financial condition. Rather, the market or fair value of the derivative transactions are reported in the consolidated statements of financial condition as other assets or accounts payable and accrued expenses, as applicable.

For a complete discussion of our activities related to derivative instruments, see Note 14 in the notes to consolidated financial statements.

In the ordinary course of business, Stifel Bancorp has commitments to originate loans, standby letters of credit, and lines of credit. Commitments to originate loans are agreements to lend to a customer as long as there is no violation of any condition established by the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a portion of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash commitments. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if necessary, is based on the credit evaluation of the counterparty. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, commercial real estate, and residential real estate.

At December 31, 2018 and 2017, Stifel Bancorp had outstanding commitments to originate loans aggregating $146.7 million and $160.2 million, respectively. The commitments extended over varying periods of time, with all commitments at December 31, 2018, scheduled to be disbursed in the following three months.

Through Stifel Bancorp, in the normal course of business, we originate residential mortgage loans and sell them to investors. We may be required to repurchase mortgage loans that have been sold to investors in the event there are breaches of certain representations and warranties contained within the sales agreements. We may be required to repurchase mortgage loans that were sold to investors in the event that there was inadequate underwriting or fraud, or in the event that the loans become delinquent shortly after they are originated. We also may be required to indemnify certain purchasers and others against losses they incur in the event of breaches of representations and warranties and in various other circumstances, and the amount of such losses could exceed the repurchase amount of the related loans. Consequently, we may be exposed to credit risk associated with sold loans.

Standby letters of credit are irrevocable conditional commitments issued by Stifel Bancorp to guarantee the performance of a customer to a third party. Financial standby letters of credit are primarily issued to support public and private borrowing arrangements,

124

including commercial paper, bond financing, and similar transactions. Performance standby letters of credit are issued to guarantee performance of certain customers under non-financial contractual obligations. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loans to customers. Should Stifel Bancorp be obligated to perform under the standby letters of credit, it may seek recourse from the customer for reimbursement of amounts paid. At December 31, 2018 and 2017, Stifel Bancorp had outstanding letters of credit totaling $26.3 million and $82.5 million, respectively. A majority of the standby letters of credit commitments at December 31, 2018, have expiration terms that are less than one year.

Lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Lines of credit generally have fixed expiration dates. Stifel Bancorp uses the same credit policies in granting lines of credit as it does for on-balance sheet instruments. At December 31, 2018 and 2017, Stifel Bancorp had granted unused lines of credit to commercial and consumer borrowers aggregating $919.5 million and $590.5 million, respectively.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“Tax Legislation”) was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017.

In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which allows us to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. In accordance with SAB 118, we recorded an additional tax benefit of $3.0 million during 2018 for the re-measurement of certain deferred tax assets and liabilities based on the rates in which they are expected to reverse in the future. Our measurement of deferred tax taxes and our provisional analysis of the one-time repatriation transition tax is complete with no additional impact on current year earnings.

Our net deferred tax asset at December 31, 2018, includes net operating loss carryforwards of $308.1 million that expire between 2020 and 2038. Certain of our net operating loss carryforwards do not expire. A valuation allowance is recorded to the extent that it is more likely than not that any portion of the deferred tax asset will not be realized. The valuation allowance was decreased by $0.3 million. We believe the realization of the remaining net deferred tax asset of $112.0 million is more likely than not based on the ability to carry back losses against prior year taxable income for tax years before 2018 and carryforward net operating losses indefinitely after 2018, and expectations of future taxable income, which is supported by a history of cumulative income.

The current tax payable, included in accounts payable and accrued expenses, is $8.4 million and $4.2 million as of December 31, 2018 and 2017, respectively. At December 31, 2018, the Company did not have a tax receivable. At December 31, 2017, the Company had a tax receivable of $54.3 million, included in other assets, which is primarily attributable to tax deductions that the Company will realize as a result of the actions taken to maximize tax savings in response to the Tax Legislation that was enacted in the fourth quarter of 2017 and prior year tax overpayments.

As of December 31, 2018, we considered all undistributed earnings of non-U.S. subsidiaries to be permanently reinvested. Therefore, we have not provided for any U.S. deferred income taxes. Because the time or manner of repatriation is uncertain, we cannot determine the impact of local taxes, withholding taxes and foreign tax credits associated with the future repatriation of such earnings, and therefore cannot quantify the tax liability that would be payable in the event all such foreign earnings are repatriated.

Uncertain Tax Positions

As of December 31, 2018 and 2017, we had $0.3 million and $3.2 million, respectively, of gross unrecognized tax benefits, all of which, if recognized, would impact the effective tax rate. We recognize interest and penalties related to uncertain tax positions in provision for income taxes in the consolidated statements of operations. As of December 31, 2018 and 2017, we had accrued interest and penalties of $0.1 million and $0.5 million, respectively, before benefit of federal tax deduction, included in accounts payable and

126

accrued expenses in our consolidated statements of financial condition. The amount of interest and penalties recognized in our consolidated statements of operations for the years ended December 31, 2018, 2017, and 2016, was not significant.

The following table summarizes the activity related to our company’s unrecognized tax benefits from January 1, 2016 to December 31, 2018 (in thousands): 

	Year Ended December 31,
	2018			2017			2016

Ending balance	$	312		$	3,180		$	1,800

We file income tax returns with the U.S. federal jurisdiction, various states, and certain foreign jurisdictions. We are not subject to U.S. federal examination for taxable years before 2013. We are not subject to certain state and local, or non-U.S. income tax examinations for taxable years before 2010.

There is a reasonable possibility that the unrecognized tax benefits will change within the next 12 months as a result of the expiration of various statutes of limitations or for the resolution of U.S. federal and state examinations, but we do not expect this change to be material to the consolidated financial statements.

NOTE 25 – Segment Reporting

We currently operate through the following three reporting segments: Global Wealth Management, Institutional Group, and various corporate activities combined in the Other segment.

Our Global Wealth Management segment consists of two operating segments, the Private Client Group and Stifel Bancorp. The Private Client Group includes branch offices and independent contractor offices of our broker-dealer subsidiaries located throughout the United States. These branches provide securities brokerage services, including the sale of equities, mutual funds, fixed income products, and insurance, as well as offering banking products to their clients through our bank subsidiaries, which provide residential, consumer, and commercial lending, as well as FDIC-insured deposit accounts to customers of our private client group and to the general public.

The Institutional Group segment includes institutional sales and trading. It provides securities brokerage, trading, and research services to institutions, with an emphasis on the sale of equity and fixed income products. This segment also includes the management of and participation in underwritings for both corporate and public finance (exclusive of sales credits generated through the private client group, which are included in the Global Wealth Management segment), merger and acquisition, and financial advisory services.

The Other segment includes interest income from stock borrow activities, unallocated interest expense, interest income and gains and losses from investments held, compensation expense associated with the expensing of restricted stock awards with no continuing service requirements in conjunction with recent acquisitions and the actions taken by the Company in response to the Tax Regulation enacted in the fourth quarter of 2017, amortization of stock-based awards, and all unallocated overhead cost associated with the execution of orders; processing of securities transactions; custody of client securities; receipt, identification, and delivery of funds and securities; compliance with regulatory and legal requirements; internal financial accounting and controls; and general administration and acquisition charges.

NOTE 26 – Earnings Per Share (“EPS”)

Basic EPS is computed by dividing earnings available to common shareholders by the weighted-average number of common shares outstanding. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. Diluted earnings per share include dilutive stock options and stock units under the treasury stock method.

128

The following table sets forth the computation of basic and diluted earnings per share for the years ended December 31, 2018, 2017, and 2016 (in thousands, except per share data):

	Year Ended December 31,
	2018		2017		2016
Net income	$	393,968	$	182,871	$	81,520
Preferred dividends		9,375		9,375		3,906
Net income available to common shareholders	$	384,593	$	173,496	$	77,614
Shares for basic and diluted calculation:
Average shares used in basic computation		71,786		68,562		66,871
Dilutive effect of stock options and units (1)		9,535		12,473		10,692
Average shares used in diluted computation		81,321		81,035		77,563
Earnings per common share:
Basic	$	5.36	$	2.53	$	1.16
Diluted	$	4.73	$	2.14	$	1.00

⁽¹⁾ Diluted earnings per share is computed on the basis of the weighted-average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Diluted earnings per share include stock options and units.

For the years ended December 31, 2018, 2017, and 2016, the anti-dilutive effect from restricted stock units was immaterial.

Cash Dividends

During the year ended December 31, 2018, we declared and paid cash dividends of $0.48 per common share. During the year ended December 31, 2017, we declared and paid cash dividends of $0.20 per common share. We did not declare or pay any dividends on our common stock during 2016.

NOTE 27 – Shareholders’ Equity

Share Repurchase Program

We have an ongoing authorization from the Board of Directors to repurchase our common stock in the open market or in negotiated transactions. In November 2018, the Board of Directors authorized the repurchase of an additional 5.3 million shares bringing the authorized share repurchase amount to 10.0 million shares. At December 31, 2018, the maximum number of shares that may yet be purchased under this plan was 9.0 million. The repurchase program has no expiration date. These purchases may be made on the open market or in privately negotiated transactions, depending upon market conditions and other factors. Repurchased shares may be used to meet obligations under our employee benefit plans and for general corporate purposes. During the year ended December 31, 2018, we repurchased $170.2 million or 3.4 million shares using existing Board authorization at an average price of $49.59 per share to meet obligations under our company’s employee benefit plans and for general corporate purposes. During the year ended December 31, 2017, we repurchased $13.0 million or 0.3 million shares using existing Board authorization at an average price of $43.83 per share to meet obligations under our company’s employee benefit plans and for general corporate purposes.

Issuance of Common Stock from Treasury

During the year ended December 31, 2018, we issued 0.5 million shares of common stock from treasury.

Share issuances out of treasury during the year ended December 31, 2018, were primarily a result of the vesting and exercise transactions under our incentive stock award plans.

During the year ended December 31, 2017, we issued 2.4 million shares of common stock from treasury.

Share issuances out of treasury during the year ended December 31, 2017, were primarily a result of the vesting and exercise transactions under our incentive stock award plans.

Issuance of Common Stock

On August 31, 2018, we issued approximately 2.0 million shares for acquisition of Business Bancshares, Inc. See Note 3 in the notes to consolidated financial statements for additional information regarding the acquisition.

On January 3, 2017, we issued 0.2 million shares related to the purchase of City Securities, Inc. See Note 3 in the notes to consolidated financial statements for additional information regarding the acquisition.

Issuance of Preferred Stock

On July 11, 2016, our company issued $150.0 million of perpetual 6.25% Non-Cumulative Perpetual Preferred Stock, Series A, $1.00 par value, with a liquidation preference of $25,000 per share (equivalent to $25 liquidation preference per depositary share).

129

When, as, and if declared by the board of directors of the company, dividends will be payable at an annual rate of 6.25%, payable quarterly, in arrears. We may redeem the Series A preferred stock at our option, subject to regulatory approval, on or after July 15, 2021, or following a regulatory capital treatment event, as defined.

NOTE 28 – Variable Interest Entities

Our company’s involvement with VIEs is limited to entities used as investment vehicles and private equity funds, the establishment of Stifel Financial Capital Trusts, and the ownership of a securitization that purchases, leases, and disposes of aircraft engines.

We have formed several non-consolidated investment funds with third-party investors that are typically organized as limited liability companies (“LLCs”) or limited partnerships. These partnerships and LLCs have assets of $231.8 million at December 31, 2018. For those funds where we act as the general partner, our company’s economic interest is generally limited to management fee arrangements as stipulated by the fund operating agreements. We have generally provided the third-party investors with rights to terminate the funds or to remove us as the general partner. Management fee revenue earned by our company was insignificant during the years ended December 31, 2018, 2017, and 2016. In addition, our direct investment interest in these entities is insignificant at December 31, 2018 and 2017.

Thomas Weisel Capital Management LLC, a subsidiary of our company, acts as the general partner of a series of investment funds in venture capital and fund of funds and manages investment funds that are active buyers of secondary interests in private equity funds, as well as portfolios of direct interests in venture-backed companies. These partnerships have combined assets of $227.0 million at December 31, 2018. We hold variable interests in these funds as a result of our company’s rights to receive management fees. Our company’s investment in and additional capital commitments to the private equity funds are also considered variable interests. The additional capital commitments are subject to call at a later date and are limited in amount. Our exposure to loss is limited to our investments in, advances and commitments to, and receivables due from these funds, and that exposure is insignificant at December 31, 2018. Management fee revenue earned by our company was insignificant during the years ended December 31, 2018, 2017, and 2016.

For the entities noted above that were determined to be VIEs, we have concluded that we are not the primary beneficiary, and therefore, we are not required to consolidate these entities. Additionally, for certain other entities, we reviewed other relevant accounting guidance, which states the general partner in a limited partnership is presumed to control that limited partnership. The presumption may be overcome if the limited partners have either: (1) the substantive ability to dissolve the limited partnership or otherwise remove the general partner without cause, or (2) substantive participating rights, which provide the limited partners with the ability to effectively participate in significant decisions that would be expected to be made in the ordinary course of the limited partnership’s business and thereby preclude the general partner from exercising unilateral control over the partnership. If the criteria are not met, the consolidation of the partnership or limited liability company is required. Based on our evaluation of these entities, we determined that these entities do not require consolidation.

Debenture to Stifel Financial Capital Trusts

We have completed private placements of cumulative trust preferred securities through Stifel Financial Capital Trust II, Stifel Financial Capital Trust III, and Stifel Financial Capital Trust IV (collectively, the “Trusts”). The Trusts are non-consolidated wholly owned business trust subsidiaries of our company and were established for the limited purpose of issuing trust securities to third parties and lending the proceeds to our company.

The trust preferred securities represent an indirect interest in junior subordinated debentures purchased from our company by the Trusts, and we effectively provide for the full and unconditional guarantee of the securities issued by the Trusts. We make timely payments of interest to the Trusts as required by contractual obligations, which are sufficient to cover payments due on the securities issued by the Trusts, and believe that it is unlikely that any circumstances would occur that would make it necessary for our company to make payments related to these Trusts other than those required under the terms of the debenture agreements and the trust preferred securities agreements. The Trusts were determined to be VIEs because the holders of the equity investment at risk do not have adequate decision-making ability over the Trust’s activities. Our investment in the Trusts is not a variable interest, because equity interests are variable interests only to the extent that the investment is considered to be at risk. Because our investment was funded by the Trusts, it is not considered to be at risk.

Securitization Interests

On July 31, 2018, the Company purchased 100% of the share capital of Jet Holding S.a.r.l. (“Jet Holdings”), which is the owner of 100% of the outstanding E-Certificates in FAN Engine Securitization Ltd. (“FAN”). FAN is a securitization which purchases, leases, and disposes of commercial aircraft engines. As of the acquisition date, FAN owned 24 leased aircraft engines through common law trusts and FAN Leasing Dublin Limited, all of which are wholly owned subsidiaries of FAN.

As the holder of the E-Certificate, our obligation to absorb losses is limited to the equity at risk (in this instance the consideration paid to acquire the E-Certificate). The residual returns that could be potentially generated by the activities of FAN are not pro rata with our ownership interests in the securitization.  In addition, we have the power to direct the activities of FAN. As such, we have determined that FAN is a variable interest entity with Jet Holdings the primary beneficiary; therefore, FAN has been consolidated at December 31, 2018.  Upon consolidation of FAN at fair value, which we determined was not a business, we recognized a gain of $15.3 million, which is included in other income in the consolidated statements of operations.

130

At December 31, 2018, the assets of FAN, which primarily consisted of operating leases, and liabilities, which primarily consisted of debt, were immaterial to our consolidated statements of financial condition.

NOTE 29 – Subsequent Events

We evaluate subsequent events that have occurred after the balance sheet date but before the financial statements are issued. There are two types of subsequent events: (1) recognized, or those that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements, and (2) non-recognized, or those that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date.

ITEM 9A. CONTROLS AND PROCEDURES

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

As of the end of the period covered by this report, an evaluation was carried out by the management of Stifel Financial Corp., with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that these disclosure controls and procedures were effective as of the end of the period covered by this report. In addition, no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) occurred during the fourth quarter of our fiscal year ended December 31, 2018, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

Management of Stifel Financial Corp., together with its consolidated subsidiaries, is responsible for establishing and maintaining adequate internal control over financial reporting. Our company’s internal control over financial reporting is a process designed under the supervision of our principal executive and principal financial officers to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our consolidated financial statements for external purposes in accordance with U.S. generally accepted accounting principles. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Management has assessed the effectiveness of our company’s internal control over financial reporting as of December 31, 2018. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework (2013). Management has excluded the operations of The Business Bank of St. Louis, a subsidiary of Business Bancshares, Inc., acquired during 2018, which is described in Note 3 of the consolidated financial statements of the Company included in this Annual Report on Form 10-K, and constituted 4.1% and 2.4% of total and net assets, respectively, as of December 31, 2018 and 0.3% and 0.2% of revenues and net income, respectively, for the year then ended, from the scope of this assessment.

Based on management’s assessment and those criteria, we conclude that, as of December 31, 2018, our company’s internal control over financial reporting is effective.

Our internal control over financial reporting includes those policies and procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets; provide reasonable assurances that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of management and directors of our company; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our company’s assets that could have a material effect on our consolidated financial statements.

Our company’s internal control over financial reporting as of December 31, 2018, has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report appearing on the following page, which expresses an unqualified opinion on the effectiveness of our company’s internal control over financial reporting as of December 31, 2018.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of Stifel Financial Corp.

Opinion on Internal Control over Financial Reporting

We have audited Stifel Financial Corp.’s internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria).  In our opinion, Stifel Financial Corp. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on the COSO criteria.

As indicated in the accompanying Management’s Report on Internal Control Over Financial Reporting, management’s assessment of and conclusions on the effectiveness of internal control over financial reporting did not include the Internal controls of The Business Bank of St. Louis, a subsidiary of Business Bancshares, Inc., which is included in the 2018 consolidated financial statements of the Company and constituted 4.1% and 2.4% of total and net assets, respectively, as of December 31, 2018 and 0.3% and 0.2% of revenues and net income, respectively, for the year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of The Business Bank of St. Louis.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statements of financial condition of Stifel Financial Corp. as of December 31, 2018 and 2017, and the related consolidated statements of operations, comprehensive income, changes in shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2018 and the related notes, and our report dated February 20, 2019, expressed an unqualified opinion thereon.

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.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS

Securities authorized for issuance under equity compensation plans

The following table provides information as of December 31, 2018, with respect to the shares of our common stock that may be issued under our existing equity compensation plans. 

Plan category	Number of securities to be issued upon exercise of outstanding options and units		Weighted- average exercise price of outstanding options and units		Number of securities remaining available for future issuance under equity compensation plans
Equity compensation plans approved by the shareholders		15,004,418	$	43.58		5,241,406
Equity compensation plans not approved by the shareholders		—		—		—
		15,004,418	$	43.58		5,241,406

As of December 31, 2018, the total number of securities to be issued upon exercise of options and units consisted of 15,004,418 units. Those shares are issuable pursuant to the Stifel Financial Corp. 2001 Incentive Stock Plan (2018 Restatement), the 2007 Incentive Stock Plan, and the Equity Incentive Plan for Non-Employee Directors.

As of December 31, 2018, the remaining shares available for future grants or awards under equity compensation plans approved by the shareholders consist of 5,241,406 shares under the 2001 Incentive Stock Plan (2018 Restatement).  

The number of securities remaining available for future issuance under equity compensation plans reflects an adjustment to outstanding awards granted under the Stifel Financial Corp. 2001 Incentive Stock Plan (2018 Restatement) to net shares withheld in payment of tax withholding obligations, due to a recent determination by the Compensation Committee to satisfy tax withholding obligations through the cancellation of shares subject to an award.

If an outstanding award granted under the 2001 Incentive Stock Plan (2018 Restatement) expires or is canceled or forfeited without having been exercised in full, the number of shares underlying such unexercised award will again become available for issuance.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Nature Of Operations And Basis Of Presentation

NOTE 1 – Nature of Operations and Basis of Presentation

Nature of Operations

Stifel Financial Corp. (the “Company”), through its wholly owned subsidiaries, is principally engaged in retail brokerage; securities trading; investment banking; investment advisory; retail, consumer, and commercial banking; and related financial services. Our major geographic area of concentration is throughout the United States, with a growing presence in the United Kingdom and Europe. Our company’s principal customers are individual investors, corporations, municipalities, and institutions.

Basis of Presentation

The consolidated financial statements include Stifel Financial Corp. and its wholly owned subsidiaries, principally Stifel, Nicolaus & Company, Incorporated (“Stifel”), Keefe Bruyette & Woods (“KBW”), and Stifel Bancorp, Inc. (“Stifel Bancorp”). Unless otherwise indicated, the terms “we,” “us,” “our,” or “our company” in this report refer to Stifel Financial Corp. and its wholly owned subsidiaries.

The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles, which require management to make certain estimates and assumptions that affect the reported amounts. We consider significant estimates, which are most susceptible to change and impacted significantly by judgments, assumptions, and estimates, to be: valuation of financial instruments and investments in partnerships, accrual for contingencies, allowance for loan losses, derivative instruments and hedging activities, fair value of goodwill and intangible assets, provision for income taxes and related tax reserves, and forfeitures associated with stock-based compensation. Actual results could differ from those estimates.

Certain amounts from prior periods have been reclassified to conform to the current period’s presentation. The effect of these reclassifications on our company’s previously reported consolidated financial statements was not material.

Consolidation Policies

The consolidated financial statements include the accounts of Stifel Financial Corp. and its subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. For consolidated subsidiaries that are less than wholly owned, the third-party holdings of equity interests are referred to as non-controlling interests. The portion of shareholders’ equity that is attributable to non-controlling interests for such subsidiaries is presented as non-controlling interests, a component of total equity, in the consolidated statements of financial condition.

Our non-controlling interest represents a 27.5% third-party ownership of North Shore Aviation Holdings LLC (“North Shore”), a wholly owned subsidiary of the Company, that through its subsidiary owns 5 airplane engines. See Note 9 for additional information on operating leases.

We also have investments or interests in other entities for which we must evaluate whether to consolidate by determining whether we have a controlling financial interest or are considered to be the primary beneficiary. In determining whether to consolidate these entities, we evaluate whether the entity is a voting interest entity or a variable interest entity (“VIE”). When we do not have a controlling interest in an entity, but we exert significant influence over the entity, we apply the equity method of accounting.

Voting Interest Entity – Voting interest entities are entities that have (i) total equity investment at risk sufficient to fund expected future operations independently, and (ii) equity holders who have the obligation to absorb losses or receive residual returns and the right to make decisions about the entity’s activities. We consolidate voting interest entities when we determine that there is a controlling financial interest, usually ownership of all, or a majority of, the voting interest.

Variable Interest Entity – VIEs are entities that lack one or more of the characteristics of a voting interest entity. We are required to consolidate certain VIEs in which we have the power to direct the activities of the entity and the obligation to absorb significant losses or receive significant benefits. In other cases, we consolidate VIEs when we are deemed to be the primary beneficiary. The primary beneficiary is defined as the entity that has a variable interest, or a combination of variable interests, that maintains control and receives benefits or will absorb losses that are not pro rata with its ownership interests.

The determination as to whether an entity is a VIE is based on the structure and nature of the entity. We also consider other characteristics, such as the ability to influence the decision-making relative to the entity’s activities and how the entity is financed. With the exception of entities eligible for the deferral codified in Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2010-10, “Consolidation: Amendments for Certain Investment Funds” (“ASU 2010-10”) (generally asset managers and investment companies), ASC 810 states that a controlling financial interest in an entity is present when an enterprise has a variable interest, or combination of variable interests, that have both the power to direct the activities of the entity that most significantly impact the entity’s economic performance and the obligation to absorb losses of the entity or the rights to receive benefits from the entity that could potentially be significant to the entity.

Entities meeting the deferral provision defined by ASU 2010-10 are evaluated under the historical VIE guidance. Under the historical guidance, a controlling financial interest in an entity is present when an enterprise has a variable interest, or combination of variable interests, that will absorb a majority of the entity’s expected losses, receive a majority of the entity’s expected residual returns, or both. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE.

We determine whether we are the primary beneficiary of a VIE by first performing a qualitative analysis of the VIE’s control structure, expected benefits and losses, and expected residual returns. This analysis includes a review of, among other factors, the VIE’s capital structure, contractual terms, which interests create or absorb benefits or losses, variability, related party relationships, and the design of the VIE. Where a qualitative analysis is not conclusive, we perform a quantitative analysis. We reassess our initial evaluation of an entity as a VIE and our initial determination of whether we are the primary beneficiary of a VIE upon the occurrence of certain reconsideration events. See Note 28 for additional information on VIEs.

Accounting Policies [Abstract]

Summary Of Significant Accounting Policies

NOTE 2 – Summary of Significant Accounting Policies

Cash and Cash Equivalents

We consider money market mutual funds and highly liquid investments with original maturities of three months or less that are not restricted or segregated to be cash equivalents. Cash and cash equivalents include deposits with banks, federal funds sold, money market mutual funds, and certificates of deposit. Cash and cash equivalents also include balances that our bank subsidiaries maintain at the Federal Reserve Bank.

Cash Segregated for Regulatory Purposes

Our broker-dealer subsidiaries are subject to Rule 15c3-3 under the Securities Exchange Act of 1934, which requires our company to maintain cash or qualified securities in a segregated reserve account for the exclusive benefit of its clients. In accordance with Rule 15c3-3, our company has portions of its cash segregated for the exclusive benefit of clients at December 31, 2018.

Brokerage Client Receivables, Net

Brokerage client receivables include receivables of our company’s broker-dealer subsidiaries, which represent amounts due on cash and margin transactions and are generally collateralized by securities owned by clients. Brokerage client receivables, primarily consisting of floating-rate loans collateralized by customer-owned securities, are charged interest at rates similar to other such loans made throughout the industry. The receivables are reported at their outstanding principal balance net of allowance for doubtful accounts. When a brokerage client receivable is considered to be impaired, the amount of the impairment is generally measured based on the fair value of the securities acting as collateral, which is measured based on current prices from independent sources, such as listed market prices or broker-dealer price quotations. Securities owned by customers, including those that collateralize margin or other similar transactions, are not reflected in the consolidated statements of financial condition.

Securities Borrowed and Securities Loaned

Securities borrowed require our company to deliver cash to the lender in exchange for securities and are included in receivables from brokers, dealers, and clearing organizations in the consolidated statements of financial condition. For securities loaned, we generally receive collateral in the form of cash in an amount in excess of the market value of securities loaned. Securities loaned are included in payables to brokers, dealers, and clearing organizations in the consolidated statements of financial condition. We monitor the market value of securities borrowed and loaned on a daily basis, with additional collateral obtained or refunded as necessary. Fees received or paid are recorded in interest revenue or interest expense in the consolidated statements of operations.

Substantially all of these transactions are executed under master netting agreements, which gives us right of offset in the event of counterparty default; however, such receivables and payables with the same counterparty are not set off in the consolidated statements of financial condition.

Securities Purchased Under Agreements to Resell and Repurchase Agreements

Securities purchased under agreements to resell (“resale agreements”) are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. We obtain control of collateral with a market value equal to or in excess of the principal amount loaned and accrued interest under resale agreements. These agreements are short-term in nature and are generally collateralized by U.S. government securities, U.S. government agency securities, and corporate bonds. We value collateral on a daily basis, with additional collateral obtained when necessary to minimize the risk associated with this activity.

Securities sold under agreements to repurchase (“repurchase agreements”) are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. We make delivery of securities sold under agreements to repurchase and monitor the value of collateral on a daily basis. When necessary, we will deliver additional collateral.

Financial Instruments

We measure certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents, financial instruments owned, available-for-sale securities, investments, financial instruments sold, but not yet purchased, and derivatives. Other than those separately discussed in the notes to the consolidated financial statements, the remaining financial instruments are generally short-term in nature, and their carrying values approximate fair value.

The fair value of a financial instrument is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., “the exit price”) in an orderly transaction between market participants at the measurement date. We have categorized our financial instruments measured at fair value into a three-level classification in accordance with Topic 820, “Fair Value Measurement,” which established a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed 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. The hierarchy is broken down into three levels based on the transparency of inputs as follows:

Level 1 – Quoted prices (unadjusted) are available in active markets for identical assets or liabilities as of the measurement date. A quoted price for an identical asset or liability in an active market provides the most reliable fair value measurement, because it is directly observable to the market.

Level 2 – Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the measurement date. The nature of these financial instruments includes instruments for which quoted prices are available but traded less frequently, derivative instruments whose fair value have been derived using a model where inputs to the model 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 measurement date. These financial instruments do not have two-way markets and 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.

Valuation of Financial Instruments

When available, we use observable market prices, observable market parameters, or broker or dealer prices (bid and ask prices) to derive the fair value of financial instruments. In the case of financial instruments transacted on recognized exchanges, the observable market prices represent quotations for completed transactions from the exchange on which the financial instrument is principally traded.

A substantial percentage of the fair value of our financial instruments owned, available-for-sale securities, investments, and financial instruments sold, but not yet purchased, are based on observable market prices, observable market parameters, or derived from broker or dealer prices. The availability of observable market prices and pricing parameters can vary from product to product. Where available, observable market prices and pricing or market parameters in a product may be used to derive a price without requiring significant judgment. In certain markets, observable market prices or market parameters are not available for all products, and fair value is determined using techniques appropriate for each particular product. These techniques involve some degree of judgment.

For investments in illiquid or privately held securities that do not have readily determinable fair values, the determination of fair value requires us to estimate the value of the securities using the best information available. Among the factors we consider in determining the fair value of investments are the cost of the investment, terms and liquidity, developments since the acquisition of the investment, the sales price of recently issued securities, the financial condition and operating results of the issuer, earnings trends and consistency of operating cash flows, the long-term business potential of the issuer, the quoted market price of securities with similar quality and yield that are publicly traded, and other factors generally pertinent to the valuation of investments. In instances where a security is subject to transfer restrictions, the value of the security is based primarily on the quoted price of a similar security without restriction but may be reduced by an amount estimated to reflect such restrictions. The fair value of these investments is subject to a high degree of volatility and may be susceptible to significant fluctuation in the near term, and the differences could be material.

The degree of judgment used in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Pricing observability is impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, and the characteristics specific to the transaction. Financial instruments with readily available active quoted prices for which fair value can be measured from actively quoted prices generally will have a higher degree of pricing observability and a lesser degree of judgment used in measuring fair value. Conversely, financial instruments rarely traded or not quoted will generally have less, or no, pricing observability and a higher degree of judgment used in measuring fair value. See Note 5 for additional information on how we value our financial instruments.

Available-for-Sale and Held-to-Maturity Securities

Securities available for sale, which are carried at fair value, include U.S. government agency securities; state and municipal securities; agency, non-agency, and commercial mortgage-backed securities; corporate fixed income securities; and asset-backed securities, which primarily includes collateralized loan obligations.

Securities held to maturity are recorded at amortized cost based on our company’s positive intent and ability to hold these securities to maturity. Securities held to maturity include agency, commercial, and non-agency mortgage-backed securities, asset-backed securities, consisting of collateralized loan obligation securities and ARS, and corporate fixed income securities.

We evaluate all securities in an unrealized loss position quarterly to assess whether the impairment is other-than-temporary. Our other-than-temporary impairment (“OTTI”) assessment is a subjective process requiring the use of judgments and assumptions. Accordingly, we consider a number of qualitative and quantitative criteria in our assessment, including the extent and duration of the impairment, recent events specific to the issuer and/or industry to which the issuer belongs, the payment structure of the security, external credit ratings and the failure of the issuer to make scheduled interest or principal payments, the value of underlying collateral, current market conditions, and our company’s ability and intent to hold the investment until its value recovers or the securities mature. We may determine that the decline in fair value of an investment is other-than-temporary if our analysis of these factors indicates that we will not recover our investment in the securities.

If we determine that impairment on our debt securities is other-than-temporary and we have made the decision to sell the security or it is more likely than not that we will be required to sell the security prior to recovery of its amortized cost basis, we recognize the entire portion of the impairment in earnings. If we have not made a decision to sell the security and we do not expect that we will be required to sell the security prior to recovery of the amortized cost basis, we recognize only the credit component of OTTI in other operating expenses in the consolidated statements of operations. The remaining unrealized loss due to factors other than credit, or the non-credit component, is recorded in accumulated other comprehensive loss. We determine the credit component based on the difference between the security’s amortized cost basis and the present value of its expected future cash flows, discounted based on the purchase yield. The non-credit component represents the difference between the security’s fair value and the present value of expected future cash flows.

We estimate the portion of loss attributable to credit using a discounted cash flow model. Key assumptions used in estimating the expected cash flows include default rates, loss severity, and prepayment rates. Assumptions used can vary widely based on the collateral underlying the securities and are influenced by factors such as collateral type, loan interest rate, geographical location of the borrower, and borrower characteristics.

Unrealized gains and losses on our available-for-sale securities are reported, net of taxes, in accumulated other comprehensive loss included in shareholders’ equity. Amortization of premiums and accretion of discounts are recorded as interest income in the consolidated statements of operations using the interest method. Realized gains and losses from sales of securities available for sale are determined on a specific identification basis and are included in other income in the consolidated statements of operations in the period they are sold. For securities transferred from available-for-sale to held-to-maturity, carrying value also includes unrealized gains and losses recognized in accumulated other comprehensive loss at the date of transfer. Such unrealized gains or losses are accreted over the remaining life of the security with no impact on future net income.

Loan Classification

We classify loans based on our investment strategy and management’s assessment of our intent and ability to hold loans for the foreseeable future or until maturity. Management’s intent and ability with respect to certain loans may change from time to time depending on a number of factors, including economic, liquidity, and capital conditions. The accounting and measurement framework for loans differs depending on the loan classification. The classification criteria and accounting and measurement framework for bank loans and loans held for sale are described below.

Bank Loans and Allowance for Loan Losses

Bank loans consist of commercial and residential mortgage loans, commercial and industrial loans, stock-secured loans, home equity loans, construction loans, and consumer loans originated or acquired by Stifel Bancorp. Bank loans include those loans that management has the intent and ability to hold and are recorded at outstanding principal adjusted for any charge-offs, allowance for loan losses, deferred origination fees and costs, and purchased discounts. Loan origination costs, net of fees, and premiums and discounts on purchased loans are deferred and recognized over the contractual life of the loan as an adjustment of yield using the interest method. Bank loans are generally collateralized by real estate, real property, marketable securities, or other assets of the borrower. Interest income is recognized using the effective interest rate method, which is based upon the respective interest rates and the average daily asset balance. Discount accretion/premium amortization is recognized using the effective interest rate method, which is based upon the respective interest rate and expected lives of loans.

We regularly review the loan portfolio and have established an allowance for loan losses for inherent losses estimated to have occurred in the loan portfolio through a provision for loan losses charged to other operating expenses in the consolidated statements of operations. In providing for the allowance for loan losses, we consider historical loss experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available.

Loans Held for Sale

Loans that we intend to sell or for which we do not have the ability and intent to hold for the foreseeable future are classified as held for sale. Loans held for sale consist of fixed-rate and adjustable-rate residential and multi-family real estate mortgage loans intended for sale. Loans held for sale are stated at lower of cost or market value on an individual loan basis. Declines in market value below cost and any gains or losses on the sale of these assets are recognized in other income in the consolidated statements of operations. Market value is determined based on prevailing market prices for loans with similar characteristics or on sale contract prices. Deferred fees and costs related to these loans are not amortized but are recognized as part of the cost basis of the loan at the time it is sold. Because loans held for sale are reported at lower of cost or market value, an allowance for loan losses is not established for loans held for sale.

Impaired Loans

A loan is considered impaired when, based on current information and events, it is probable that the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement will not be collectible. Factors considered in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. We determine the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed.

We consider a loan a trouble debt restructuring when an existing borrower is granted concessionary rates or terms, which would not otherwise be offered. The concessions granted do not reflect current market conditions for a new loan of similar risk to another borrower in similar financial circumstances.

Once a loan is determined to be impaired, when principal or interest becomes 90 days past due or when collection becomes uncertain, the accrual of interest and amortization of deferred loan origination fees is discontinued (“non-accrual status”) and any accrued and unpaid interest income is reversed. Loans placed on non-accrual status are returned to accrual status when all delinquent principal and interest payments are collected and the collectibility of future principal and interest payments is reasonably assured. Loan losses are charged against the allowance for loan losses when we believe the uncollectibility of a loan balance is certain. Subsequent recoveries, if any, are credited to the allowance for loan losses.

Large groups of smaller balance homogenous loans are collectively evaluated for impairment. Accordingly, we do not separately identify individual consumer and residential loans for impairment measurements. Impairment is measured on a loan-by-loan basis for non-homogeneous loans, and a specific allowance is established for individual loans determined to be impaired. Impairment is measured by comparing the carrying value of the impaired loan to the present value of its expected cash flow discounted at the loan’s effective interest rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent.

Investments

Our broker-dealer subsidiaries report changes in fair value of marketable and non-marketable securities in other income in the consolidated statements of operations. The fair value of marketable investments is generally based on either quoted market or dealer prices. The fair value of non-marketable securities is based on management’s estimate using the best information available, which generally consists of quoted market prices for similar securities and internally developed discounted cash flow models.

Investments in the consolidated statements of financial condition contain investments in securities that are marketable and securities that are not readily marketable. These investments are not included in our broker-dealer trading inventory or available-for-sale or held-to-maturity portfolios and represent the acquiring and disposing of debt or equity instruments for our benefit.

Fixed Assets, Net

Office equipment is depreciated on a straight-line basis over the estimated useful life of the asset of two to seven years. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or the term of the lease. Buildings and building improvements are amortized on a straight-line basis over the estimated useful life of the asset of three to thirty-nine years. Depreciation expense is recorded in occupancy and equipment rental in the consolidated statements of operations. Office equipment, leasehold improvements, and property are stated at cost net of accumulated depreciation and amortization in the consolidated statements of financial condition. Fixed assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable.

Goodwill and Intangible Assets

Goodwill represents the cost of acquired businesses in excess of the fair value of the related net assets acquired. We test goodwill for impairment on an annual basis and on an interim basis when certain events or circumstances exist. We test for impairment at the reporting unit level, which is generally at the level of or one level below our company’s business segments. For both the annual and interim tests, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads 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 or circumstances, we determine it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then performing the two-step impairment test is not required. However, if we conclude otherwise, we are then required to perform the first step of the two-step impairment test. Goodwill impairment is determined by comparing the estimated fair value of a reporting unit with its respective carrying value. If the estimated fair value exceeds the carrying value, goodwill at the reporting unit level is not deemed to be impaired. If the estimated fair value is below carrying value, however, further analysis is required to determine the amount of the impairment. Additionally, if the carrying value of a reporting unit is zero or a negative value and it is determined that it is more likely than not the goodwill is impaired, further analysis is required. The estimated fair values of the reporting units are derived based on valuation techniques we believe market participants would use for each of the reporting units. The Company performed impairment testing on October 1, 2018 with no impairment charges resulting from the annual impairment tests.

Identifiable intangible assets, which are amortized over their estimated useful lives, are tested for potential impairment whenever events or changes in circumstances suggest that the carrying value of an asset or asset group may not be fully recoverable.

Loans and Advances to Financial Advisors and Other Employees, Net

We offer transition pay, principally in the form of upfront loans, to financial advisors and certain key revenue producers as part of our company’s overall growth strategy. These loans are generally forgiven by a charge to compensation and benefits over a five- to ten-year period if the individual satisfies certain conditions, usually based on continued employment and certain performance standards. We monitor and compare individual financial advisor production to each loan issued to ensure future recoverability. If the individual leaves before the term of the loan expires or fails to meet certain performance standards, the individual is required to repay the balance. In determining the allowance for doubtful receivables from former employees, management considers the facts and circumstances surrounding each receivable, including the amount of the unforgiven balance, the reasons for the terminated employment relationship, and the former employees’ overall financial situation.

Derivative Instruments and Hedging Activities

We recognize all of our derivative instruments at fair value as either assets or liabilities in the consolidated statements of financial condition. These instruments are recorded in other assets or accounts payable and accrued expenses in the consolidated statements of financial condition and in the operating section of the consolidated statements of cash flows as increases or decreases of other assets and accounts payable and accrued expenses. Our company’s policy is not to offset fair value amounts recognized for derivative instruments and fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral arising from derivative instruments recognized at fair value executed with the same counterparty under master netting arrangements. The accounting for changes in the fair value (i.e., gains and losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, we must also designate the hedging instrument or transaction, based upon the exposure being hedged.

For derivative instruments that are designated and qualify as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive loss, net of tax, and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item, if any, is recognized in current earnings during the period of change. We do not use derivatives for trading or speculative purposes and, at December 31, 2018, all of our derivatives are designated as cash flow hedges. See Note 14 for additional details.

Revenue Recognition

Customer securities transactions are recorded on a settlement date basis, with related commission revenues and expenses recorded on a trade date basis. Commission revenues are recorded as the amount charged to the customer, which, in certain cases, may include varying discounts. Principal securities transactions are recorded on a trade date basis. We typically distribute our proprietary equity research products to our client base of institutional investors at no charge. These proprietary equity research products are accounted for as a cost of doing business.

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.

Advisory expenses had historically been deferred until reimbursed by the client, the related fee revenue was recognized or the engagement was 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 has been recognized. All other investment banking advisory related expenses, including expenses incurred related to restructuring assignments, are expensed as incurred.

Underwriting expenses had historically been recorded net of client reimbursements and/or netted against revenues. Under the new revenue standard, all investment banking expenses are recognized as non-interest expense in other operating expenses in the consolidated statements of operations and any expense reimbursements are recognized as investment banking revenues (i.e., expenses are no longer recorded net of client reimbursements and are not netted against revenues).

Asset management and service fees. We earn management and performance fees in connection with investment advisory services provided to institutional and individual clients. Investment advisory fees are charged based on the value of assets in fee-based accounts and are affected by changes in the balances of client assets due to market fluctuations and levels of net new client assets. Fees are charged either in advance based on fixed rates applied to the value of the customers’ account at the beginning of the period or periodically based on contracted rates and account performance. Contracts can be terminated at any time with no incremental payments due to our company upon termination. If the contract is terminated by the customer fees are prorated for the period and fees charged for the post termination period are refundable to the customer.

We earn fees from the investment partnerships that we manage or of which we are a general partner. Such management fees are generally based on the net assets or committed capital of the underlying partnerships. We have agreed, in certain cases, to waive management fees, in lieu of making a cash contribution, in satisfaction of our general partner investment commitments to the investment partnerships. In these cases, we generally recognize our management fee revenues at the time when we are allocated a special profit interest in realized gains from these partnerships.

Direct Financing andOperating Leases

The net investment in direct financing leases is included in other assets in the consolidated balance sheets and consists of the present values of the sum of the future minimum lease payments and estimated residual value of the leased assets. Revenue consists of interest earned on the net investment and is recognized over the lease term as a constant percentage return thereon. The net investment in property on operating leases is included in fixed assets, net in the consolidated balance sheets. Depreciation is recognized, on the straight-line basis, over the lease term to the estimated residual value. Operating lease revenue is recorded on a straight-line basis and is recognized over the lease term in other income. Estimated residual values are established at lease inception utilizing contract terms, past customer experience, and general market data and are reviewed and adjusted, if necessary, on an annual basis. See Note 3 – Acquisitions for further details.

We lease office space and equipment under operating leases. We recognize rent expense related to these operating leases on a straight-line basis over the lease term. The lease term commences on the earlier of the date when we become legally obligated for the rent payments or the date on which we take possession of the property. For tenant improvement allowances and rent holidays, we record a deferred rent liability in accounts payable and accrued expenses in the consolidated statements of financial condition and amortize the deferred rent over the lease term as a reduction to occupancy and equipment rental in the consolidated statements of operations.

Income Taxes

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“Tax Legislation”) was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017.

We compute income taxes using the asset and liability method, under which deferred income taxes are provided for the temporary differences between the financial statement carrying amounts and the tax basis of our company’s assets and liabilities. We establish a valuation allowance for deferred tax assets if it is more likely than not that these items will either expire before we are able to realize their benefits, or that future deductibility is uncertain.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. We recognize interest and penalties related to uncertain tax positions in provision for income taxes in the consolidated statements of operations. See Note 24 for further information regarding income taxes.

Foreign Currency Translation

We consolidate our foreign subsidiaries, which have designated their local currency as their functional currency. Assets and liabilities of these foreign subsidiaries are translated at year-end rates of exchange. Revenues and expenses are translated at an average rate for the period. Gains or losses resulting from translating foreign currency financial statements are reflected in accumulated other comprehensive loss, a separate component of Stifel Financial Corp. shareholders’ equity. Gains or losses resulting from foreign currency transactions are included in other income in the consolidated statements of operations.

Recently Issued Accounting Guidance

Fair Value Measurement

In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The objective of this guidance is to improve the effectiveness of disclosure requirements on fair value measurement by eliminating certain disclosure requirements for fair value measurements for all entities, requiring public entities to disclose certain new information and modifying some disclosure requirements. The accounting update is effective for the fiscal year beginning after December 15, 2019 (January 1, 2020 for our company) and early adoption is permitted. The adoption is not expected to have a material impact on our consolidated financial statements.

Derivatives and Hedging

In August 2017, the FASB issued ASU 2017-12, “Targeted Improvements to Accounting for Hedging Activities,” which amends the hedge accounting recognition and presentation requirements. The accounting update improves the transparency and understandability of information conveyed to financial statement users by better aligning companies’ hedging relationship to their existing risk management strategies, simplifies the application of hedge accounting and increases transparency regarding the scope and results of hedging program. The accounting update is effective for the fiscal year beginning after December 15, 2018 (January 1, 2019 for our company) and early adoption is permitted. The Company will not early adopt this accounting update. We are currently evaluating the impact of the accounting update, but the adoption is not expected to have a material impact on our consolidated financial statements.

Callable debt securities

In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities,” which shortens the amortization period for the premium on certain callable debt securities to the earliest call date. The amendments are applicable to any purchased individual debt security with an explicit and non-contingent call feature that is callable at a fixed price on a preset date. The accounting update is effective for fiscal years beginning after December 15, 2018 (January 1, 2019 for our company) under a modified retrospective approach and early adoption is permitted. We are evaluating the impact the adoption of this new guidance will have on our consolidated financial statements.

Goodwill Impairment Testing

In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. Under the accounting update, the annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, and an impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The accounting update is effective for annual or any interim impairment tests in fiscal years beginning after December 15, 2019 (January 1, 2020 for our company) and early adoption is permitted. We are currently evaluating the impact of the accounting update, but the adoption is not expected to have a material impact on our consolidated financial statements.

Financial Instruments – Credit Losses

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments − Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.”  This accounting update impacts the impairment model for certain financial assets measured at amortized cost by requiring a current expected credit loss (“CECL”) methodology to estimate expected credit losses over the entire life of the financial asset, recorded at inception or purchase. CECL will replace the loss model currently applicable to bank loans, held-to-maturity securities, and other receivables carried at amortized cost.

The accounting update also eliminates the concept of other-than-temporary impairment for available-for-sale securities. Impairments on available-for-sale securities will be required to be recognized in earnings through an allowance, when the fair value is less than amortized cost and a credit loss exists or the securities are expected to be sold before recovery of amortized cost. Under the accounting update, there may be an ability to determine there are no expected credit losses in certain circumstances, e.g., based on collateral arrangements for lending and financing transactions or based on the credit quality of the borrower or issuer.

Overall, the amendments in this accounting update are expected to accelerate the recognition of credit losses for portfolios where CECL models will be applied. The accounting update is effective for fiscal years beginning after December 15, 2019 (January 1, 2020 for our company) with early adoption permitted as of January 1, 2019. We are in the process of developing credit models with the assistance of third-party vendors and assessing process changes that may be required for accounting, reporting and governance to comply with the new credit standard.  We are also currently evaluating the impact of the accounting update, but the adoption is not expected to have a material impact on our consolidated financial statements.

Leases

In February 2016, the FASB issued ASU 2016-02, “Leases,” (“ASU 2016-02”) that requires for leases longer than one year, a lessee recognize in the statements of financial condition a right-of-use asset, representing the right to use the underlying asset for the lease term, and a lease liability, representing the liability to make lease payments. The accounting update also requires that for finance leases, a lessee recognize interest expense on the lease liability, separately from the amortization of the right-of-use asset in the statements of earnings, while for operating leases, such amounts should be recognized as a combined expense. In addition, this accounting update requires expanded disclosures about the nature and terms of lease agreements.

We will adopt ASU 2016-02 utilizing the optional transition approach allowed under ASU 2018-11, “Leases (Topic 842): Targeted Improvements” and applying the package of practical expedients beginning January 1, 2019. This option allows entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. By applying ASU 2016-02 at the adoption date, as opposed to at the beginning of the earliest period presented, our reporting for periods prior to January 1, 2019 will continue to be reported in accordance with Leases (Topic 840).

The adoption of this guidance will result in the addition of right-of-use assets and corresponding lease obligations to the consolidated balance sheet and will not have a material impact on the Company’s results of operations or cash flows. Upon adoption, the Company expects to record operating lease right-of-use assets in the range of approximately $600 million to $700 million, representing the present value of future lease payments under operating leases with terms of greater than twelve months, with corresponding operating lease liabilities. These amounts are impacted by certain assumptions around lease renewals and the discount rate used to discount the future lease obligations. We do not believe the standard will materially affect our consolidated statements of income or consolidated statements of cash flows. The standard will have no impact on our debt covenant compliance under our current agreements.

Recently Adopted Accounting Guidance

Comprehensive Income

In February 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” that provides for the reclassification from accumulated other comprehensive income to retained earnings for stranded effects resulting from the Tax Cuts and Jobs Act of 2017. The accounting update is effective for the fiscal year beginning after December 15, 2018 (January 1, 2019 for our company) and early adoption is permitted. We early adopted the guidance in the update on January 1, 2018. The adoption of the accounting update resulted in a reclassification adjustment of $3.1 million related to cash flow hedges and investment portfolio credit risk in our consolidated financial statements.

Statement of Cash Flow

In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flow - Restricted Cash,” which adds or clarifies guidance on the classification and presentation of restricted cash in the statement of cash flows. The accounting update is effective for the fiscal year beginning after December 15, 2017. We adopted the guidance in the update on January 1, 2018. The adoption of the accounting update did not have a material impact on our consolidated statement of cash flows. Upon adoption of the accounting update, we recorded an increase of $17.6 million in net cash provided by operating activities and an increase of $153.8 million in net cash used in operating activities for the years ended December 31, 2017 and 2016, respectively, related to reclassifying the changes in our cash segregated for regulatory purposes and restricted cash balance from operating activities to the cash and cash equivalent balances within the consolidated statements of cash flows.

In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” which amends and clarifies the current guidance to reduce diversity in practice of the classification of certain cash receipts and payments in the consolidated statements of cash flows. The accounting update is effective for the fiscal year beginning after December 31, 2017. We adopted the guidance in the update on January 1, 2018. The adoption of the accounting update did not have a material impact on our consolidated statements of cash flows.

Financial Assets and Financial Liabilities

In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” that changes the income statement impact of equity investments held by an entity, and the recognition of changes in fair value of financial liabilities when the fair value option is elected. The accounting update also amends certain disclosure requirements associated with the fair value of financial instruments. The accounting update is effective for fiscal years beginning after December 15, 2017. We adopted the guidance in the update on January 1, 2018. The adoption of the accounting update did not have a material impact on our consolidated financial statements.

Revenue Recognition

In May 2014, the FASB issued ASU 2014-09, “Revenue From Contracts With Customers (Topic 606),” (“ASU 2014-09”) that supersedes current revenue recognition guidance, including most industry-specific guidance. ASU 2014-09, as amended, requires a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services. The guidance also requires additional disclosures regarding the nature, amount, timing, and uncertainty of revenue that is recognized.

Effective January 1, 2018, the Company adopted ASU 2014-09, which provides accounting guidance on the recognition of revenues from contracts and requires gross presentation of certain costs that were previously offset against revenue. This change was applied prospectively from January 1, 2018 and there is no impact on our previously presented results. The adoption of the new revenue standard resulted in a reduction of beginning retained earnings of $4.2 million after-tax as a cumulative effect of adoption of an accounting change.

The impact of adoption is primarily related to investment banking revenues that were previously recognized in prior periods, which are now being deferred under the new revenue standard.

With the adoption of the new revenue recognition standard on January 1, 2018, capital raising and advisory fee revenues are no longer presented net of the related reimbursable deal expenses. As a result, capital raising and advisory fee revenues and other operating expenses are higher in 2018 by an identical $33.8 million, with no impact to net income.

The scope of the accounting update does not apply to revenue associated with financial instruments, and as a result, does not have an impact on the elements of our consolidated statements of operations most closely associated with financial instruments, including principal transaction revenues, interest income, and interest expense.

Share-Based Payments

In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”) that requires an entity to record all excess tax benefits and tax deficiencies as an income tax benefit or expense in the income statement. ASU 2016-09 also requires an entity to elect an accounting policy to either estimate the number of forfeitures or account for forfeitures when they occur. The guidance is effective for fiscal years beginning after December 15, 2016 (January 1, 2017 for our company). We adopted the guidance in the update on January 1, 2017. Cash paid to a tax authority by a company when withholding shares from an employee’s award for tax-withholding purposes are now classified as a financing activity in the accompanying consolidated statement of cash flows (adopted retrospectively). We reclassified $61.6 million from operating activities to financing activities in the accompanying consolidated statement of cash flows for the year ended December 31, 2016 pertaining to shares withheld from employee awards for tax withholding purposes.

Acquisitions

NOTE 3 – Acquisitions

Rand & Associates

On October 1, 2018, the Company completed the acquisition of Rand & Associates (“Rand”), an independent investment adviser that provides comprehensive wealth management and investment counsel services to individuals, families, and institutions. The acquisition was funded with cash from operations.

The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“ASC Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $8.3 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management segment. Identifiable intangible assets purchased by our company consisted of customer relationships with an acquisition-date fair value of $4.6 million. The allocation of the purchase price of Rand is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets of Rand as of the acquisition date and the identified intangible assets. The final goodwill recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments and the recording of identified intangible assets.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the Rand business and of the hired financial advisors and the conversion of the customer accounts to our platform. Goodwill is expected to be deductible for federal income tax purposes.

We recognized a liability for estimated earn-out payments. These payments will be based on the performance of Rand over a five-year period. The liability for earn-out payments was $4.1 million at December 31, 2018. The contingent consideration accrual is included in accounts payable and accrued expenses in the consolidated statements of financial condition.

Pro forma information is not presented, because the acquisition is not considered to be material, as defined by the SEC. The results of operations of Rand have been included in our results prospectively from the date of acquisition.

Business Bancshares, Inc.

On August 31, 2018, the Company completed the acquisition of Business Bancshares, Inc. (“BBI”) and its wholly owned subsidiary, The Business Bank of St. Louis, a full-service banking facility that operates from a single location. Upon the closing of the transaction, the Business Bank of St. Louis was renamed “Stifel Bank” and Business Bancshares, Inc. was renamed “Stifel Bancorp, Inc.” Stifel Bancorp, Inc. (“Stifel Bancorp”) is the holding company for Stifel Bank & Trust, and its wholly owned subsidiaries, and Stifel Bank. Under the terms of the merger agreement, each outstanding share of BBI common stock (except for shares of BBI common stock held by BBI as treasury stock) were converted into the right to receive 0.705 shares of our company’s common stock, with fractional shares settled with cash. We issued approximately 2.0 million shares for acquisition of BBI.

We acquired approximately $507.8 million of loans, and $85.7 million of other assets (primarily cash and due from banks and investment securities). In addition, we assumed approximately $501.1 million of deposits and $21.9 million of other liabilities. Assets acquired and liabilities assumed were recorded at fair value. The fair values for loans were estimated using discounted cash flow analyses using interest rates currently being offered for loans with similar terms. This value was reduced by an estimate of probable losses and the credit risk associated with the loans. The fair values of deposits were estimated by discounting cash flows using interest rates currently being offered on deposits with similar maturities.

The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $38.4 million of goodwill and intangibles in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management segment. Identifiable intangible assets purchased by our company consisted of core deposits with an acquisition date fair value of $8.6 million. The allocation of the purchase price of BBI is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets of BBI as of the acquisition date and the identified intangible assets. The final goodwill recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments and the recording of identified intangible assets.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the BBI business and its customer base.

Pro forma information is not presented, because the acquisition is not considered to be material, as defined by the SEC. The results of operations of BBI have been included in our results prospectively from the date of acquisition.

Ziegler Wealth Management

On March 19, 2018, the Company completed the acquisition of Ziegler Wealth Management (“Ziegler”), a privately held investment bank, capital markets and proprietary investments firm that had 55 private client advisors in five states that managed approximately $5 billion in client assets. Ziegler provided its clients with capital raising, strategic advisory services, equity and fixed income sales & trading and research. The acquisition was funded with cash from operations.

The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“ASC Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $19.0 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management and Institutional Group segments. Identifiable intangible assets purchased by our company consisted of customer relationships and non-compete agreements with an acquisition-date fair value of $9.5 million.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the Ziegler business and of the hired financial advisors and the conversion of the customer accounts to our platform. Goodwill is expected to be deductible for federal income tax purposes.

Pro forma information is not presented, because the acquisition is not considered to be material, as defined by the SEC. The results of operations of Ziegler have been included in our results prospectively from the date of acquisition.

City Securities Corporation

On January 3, 2017, the Company completed the acquisition of City Financial Corporation and its wholly owned subsidiary, City Securities Corporation, (“City Securities”), an independent investment bank focused primarily on offering wealth management and public finance services across the Midwest. The acquisition was funded with cash from operations and our common stock.

The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“ASC Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $7.1 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management and Institutional Group segments. Identifiable intangible assets purchased by our company consisted of customer relationships with an acquisition-date fair value of $4.1 million.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the City Securities’ business and of the hired financial advisors and the conversion of the customer accounts to our platform. Goodwill is not expected to be deductible for federal income tax purposes.

Pro forma information is not presented, because the acquisition is not considered to be material, as defined by the SEC. The results of operations of City Securities have been included in our results prospectively from the date of acquisition.

ISM Capital LLP

On May 3, 2016, the Company completed the acquisition of ISM Capital LLP (“ISM”), an independent investment bank focused on international debt capital markets. The acquisition of ISM adds to the Company’s debt capital markets origination, sales, and research capabilities in Europe, including an end-to-end platform for convertible securities and other equity-linked debt instruments. The acquisition was funded with cash from operations and our common stock, issued out of treasury.

The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“ASC Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $6.3 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Institutional Group segment. Identifiable intangible assets purchased by our company consisted of customer relationships, non-compete, and customer backlog with aggregate acquisition-date fair values of $2.3 million.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of ISM’s business and the addition of an end-to-end platform for convertible securities and other equity-linked debt instruments to our debt capital markets capabilities in Europe. Goodwill is not expected to be deductible for federal income tax purposes.

We recognized a liability for estimated earn-out payments. These payments will be based on ISM’s performance over a three-year period. The liability for earn-out payments was $1.9 million at December 31, 2017. The contingent consideration accrual is included in accounts payable and accrued expenses in the consolidated statements of financial condition. There was no liability for earn-out payments at December 31, 2018.

Eaton Partners

On January 4, 2016, we completed the acquisition of Eaton Partners, LLC (“Eaton Partners”), a global fund placement and advisory firm. The acquisition was funded with cash from operations and our common stock, issued out of treasury.

The acquisition was accounted for under the acquisition method of accounting in accordance with Topic 805. Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $72.0 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Institutional Group segment. Identifiable intangible assets purchased by our company consisted of customer relationships, trade name, non-compete, and customer backlog with aggregate acquisition-date fair values of $32.3 million.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of Eaton’s business and from the relationships Eaton has established with private equity firms, hedge funds, high net worth family offices, and institutional investors. Goodwill is deductible for federal income tax purposes.

We recognized a liability for estimated earn-out payments. These payments will be based on Eaton Partner’s performance over a four-year period. The liability for earn-out payments was $40.2 million and $31.2 million at December 31, 2018 and 2017, respectively. The contingent consideration accrual is included in accounts payable and accrued expenses in the consolidated statements of financial condition.

Barclays Wealth and Investment Management, Americas

On December 4, 2015, we completed the purchase of the Barclays Wealth and Investment Management, Americas (“Barclays”), franchise in the U.S. The Company paid purchase consideration that was funded with cash from operations. As part of that transaction, Stifel Bancorp, a wholly owned subsidiary of the Company, acquired approximately $600.0 million of bank loans, at fair value, from Barclays. The fair values for those loans were estimated using discounted cash flow analyses using interest rates currently being offered for loans with similar terms.

The acquisition was accounted for under the acquisition method of accounting in accordance with Topic 805. Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $24.8 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management segment. Identifiable intangible assets purchased by our company consisted of customer relationships, with acquisition-date fair value of $7.3 million.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the hired financial advisors and the conversion of the customer accounts to the Stifel platform. Goodwill is expected to be deductible for federal income tax purposes.

In addition, deferred consideration is payable based on certain revenue generated by Stifel in accordance with the distribution agreement. The deferred consideration of $7.4 million and $15.2 million has been recognized as a liability and is included in accounts payable and accrued expenses in the consolidated statements of financial condition at December 31, 2018 and 2017, respectively.

During 2016, the Company’s Board of Directors removed the continuing service requirements associated with restricted stock units that were granted to certain employees of Barclays in December 2015. As a result, the awards were expensed at date of modification resulting in a charge of $58.6 million during 2016. The fair value of the awards is based upon the closing price of our company’s common stock on the date of the grant of the awards. These charges are included in compensation and benefits in the consolidated statements of operations for the year ended December 31, 2016.

Fair Value Measurements

NOTE 5 – Fair Value Measurements

We measure certain financial assets and liabilities at fair value on a recurring basis, including financial instruments owned, available-for-sale securities, investments, financial instruments sold, but not yet purchased, and derivatives.

We generally utilize third-party pricing services to value Level 1 and Level 2 available-for-sale investment securities, as well as certain derivatives designated as cash flow hedges. We review the methodologies and assumptions used by the third-party pricing services and evaluate the values provided, principally by comparison with other available market quotes for similar instruments and/or analysis based on internal models using available third-party market data. We may occasionally adjust certain values provided by the third-party pricing service when we believe, as the result of our review, that the adjusted price most appropriately reflects the fair value of the particular security.

Following are descriptions of the valuation methodologies and key inputs used to measure financial assets and liabilities recorded at fair value. The descriptions include an indication of the level of the fair value hierarchy in which the assets or liabilities are classified.

Financial Instruments Owned and Available-For-Sale Securities

When available, the fair value of financial instruments is based on quoted prices in active markets and reported in Level 1. Level 1 financial instruments include highly liquid instruments with quoted prices, such as equity securities listed in active markets, U.S. government securities, U.S. government agency securities, corporate equity securities, and fixed income securities.

If quoted prices are not available for identical instruments, fair values are obtained from pricing services, broker quotes, or other model-based valuation techniques with observable inputs, such as the present value of estimated cash flows, and reported as Level 2. The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, instruments whose fair value has been derived using a model where inputs to the model 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 2 financial instruments include U.S. government agency securities, mortgage-backed securities, securities infrequently traded, including corporate fixed income securities, sovereign debt, and equity securities, state and municipal securities, and asset-backed securities, which primarily includes collateralized loan obligations.

We have identified Level 3 financial instruments to include certain asset-backed and non-agency mortgage-backed securities. Level 3 financial instruments have little to no pricing observability as of the report date. These financial instruments do not have active two-way markets and 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.

Investments

Investments carried at fair value primarily include corporate equity securities, auction-rate securities (“ARS”), and private company investments.

Corporate equity securities that are valued based on quoted prices in active markets are reported in Level 1.

ARS are valued based upon our expectations of issuer redemptions and using internal discounted cash flow models that utilize unobservable inputs. ARS are reported as Level 3 assets.

Direct investments in private companies may be valued using the market approach and were valued based on an assessment of each underlying investment, incorporating evaluation of additional significant third-party financing, changes in valuations of comparable peer companies, the business environment of the companies, market indices, assumptions relating to appropriate risk adjustments for nonperformance, and legal restrictions on disposition, among other factors. The fair value derived from the methods used are evaluated and weighted, as appropriate, considering the reasonableness of the range of values indicated. Under the market approach, fair value may be determined by reference to multiples of market-comparable companies or transactions, including earnings before interest, taxes, depreciation, and amortization (“EBITDA”) multiples. For securities utilizing the market comparable companies valuation technique, a significant increase (decrease) in the EBITDA multiple in isolation could result in a significantly higher (lower) fair value measurement.

Investments in Funds That Are Measured at Net Asset Value Per Share

Investments at fair value include investments in funds, including certain money market funds that are measured at net asset value (“NAV”). The Company uses NAV to measure the fair value of its fund investments when (i) the fund investment does not have a readily determinable fair value and (ii) the NAV of the investment fund is calculated in a manner consistent with the measurement principles of investment company accounting, including measurement of the underlying investments at fair value.

The Company’s investments in funds measured at NAV include private company investments, partnership interests, mutual funds, private equity funds, and money market funds. Private equity funds primarily invest in a broad range of industries worldwide in a variety of situations, including leveraged buyouts, recapitalizations, growth investments, and distressed investments. The private equity funds are primarily closed-end funds in which the Company’s investments are generally not eligible for redemption. Distributions will be received from these funds as the underlying assets are liquidated or distributed.

The general and limited partnership interests in investment partnerships were primarily valued based upon NAVs received from third-party fund managers. The various partnerships are investment companies, which record their underlying investments at fair value based on fair value policies established by management of the underlying fund. Fair value policies at the underlying fund generally require the funds to utilize pricing/valuation information, including independent appraisals, from third-party sources. However, in some instances, current valuation information for illiquid securities or securities in markets that are not active may not be available from any third-party source or fund management may conclude that the valuations that are available from third-party sources are not reliable. In these instances, fund management may perform model-based analytical valuations that may be used as an input to value these investments.

The tables below present the fair value of our investments in, and unfunded commitments to, funds that are measured at NAV (in thousands):

	December 31, 2018				December 31, 2017
	Fair value of investments		Unfunded commitments		Fair value of investments		Unfunded commitments

Total	$	36,278	$	2,504	$	101,990	$	3,155

Financial Instruments Sold, But Not Yet Purchased

Financial instruments sold, but not purchased, recorded at fair value based on quoted prices in active markets and other observable market data include highly liquid instruments with quoted prices, such as U.S. government securities, equity securities, and fixed income securities listed in active markets, which are reported as Level 1.

If quoted prices are not available, fair values are obtained from pricing services, broker quotes, or other model-based valuation techniques with observable inputs, such as the present value of estimated cash flows, and reported as Level 2. The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, instruments whose fair value has been derived using a model where inputs to the model 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 2 financial instruments include U.S. government agency securities, mortgage-backed securities not actively traded, corporate securities, including fixed income securities and equity securities, and sovereign debt.

Derivatives

Derivatives are valued using quoted market prices for identical instruments when available or pricing models based on the net present value of estimated future cash flows. The valuation models used require market observable inputs, including contractual terms, market prices, yield curves, credit curves, and measures of volatility. We manage credit risk for our derivative positions on a counterparty-by-counterparty basis and calculate credit valuation adjustments, included in the fair value of these instruments, on the basis of our relationships at the counterparty portfolio/master netting agreement level. These credit valuation adjustments are determined by applying a credit spread for the counterparty to the total expected exposure of the derivative after considering collateral and other master netting arrangements. We have classified our interest rate swaps as Level 2.

The results included in the table above are only a component of the overall investment strategies of our company. The table above does not present Level 1 or Level 2 valued assets or liabilities. The changes to our company’s Level 3 classified instruments during the year ended December 31, 2018 were principally a result of the redemption of ARS. The changes in unrealized gains/(losses) recorded in earnings for the year ended December 31, 2018, relating to Level 3 assets still held at December 31, 2018, were immaterial.

The following table summarizes quantitative information related to the significant unobservable inputs utilized in our company’s Level 3 recurring fair value measurements as of December 31, 2018.

	Valuation technique	Unobservable input	Range	Weighted average
Investments:
Auction rate securities:
Equity securities	Discounted cash flow	Discount rate	0.0% - 5.6%	3.2%
		Workout period	2-3 years	2.4 years
Municipal securities	Discounted cash flow	Discount rate	0.7% - 8.3%	2.8%
		Workout period	1-4 years	2.0 years

The fair value of certain Level 3 assets was determined using various methodologies, as appropriate, including third-party pricing vendors and broker quotes. These inputs are evaluated for reasonableness through various procedures, including due diligence reviews of third-party pricing vendors, variance analyses, consideration of current market environment, and other analytical procedures.

The fair value for our auction rate securities was determined using an income approach based on an internally developed discounted cash flow model. The discounted cash flow model utilizes two significant unobservable inputs: discount rate and workout period. The discount rate was calculated using credit spreads of the underlying collateral or similar securities. The workout period was based on an assessment of publicly available information on efforts to re-establish functioning markets for these securities and our company’s own redemption experience. Significant increases in any of these inputs in isolation would result in a significantly lower fair value. On an ongoing basis, management verifies the fair value by reviewing the appropriateness of the discounted cash flow model and its significant inputs.

Transfers Within the Fair Value Hierarchy

We assess our financial instruments on a quarterly basis to determine the appropriate classification within the fair value hierarchy. Transfers between fair value classifications occur when there are changes in pricing observability levels. Transfers of financial instruments among the levels are deemed to occur at the beginning of the reporting period.

There were $0.9 million of transfers of financial assets from Level 2 to Level 1 during the year ended December 31, 2018, corporate fixed income securities for which market trades were observed that provided transparency into the valuation of these assets. There were $0.8 million of transfers of financial assets from Level 1 to Level 2 during the year ended December 31, 2018, primarily related to corporate fixed income securities for which there were low volumes of recent trade activity observed. There were no transfers of financial assets into or out of Level 3 during the year ended December 31, 2018.

The following, as supplemented by the discussion above, describes the valuation techniques used in estimating the fair value of our financial instruments as of December 31, 2018 and 2017.

Financial Assets

Securities Purchased Under Agreements to Resell

Securities purchased under agreements to resell are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. The carrying values at December 31, 2018 and 2017 approximate fair value due to their short-term nature.

Held-to-Maturity Securities

Securities held to maturity are recorded at amortized cost based on our company’s positive intent and ability to hold these securities to maturity. Securities held to maturity include agency, commercial, and non-agency mortgage-backed securities, asset-backed securities, consisting of collateralized loan obligation securities and Student Loan ARS, and corporate fixed income securities. The estimated fair value, included in the above table, is determined using several factors; however, primary weight is given to discounted cash flow modeling techniques that incorporated an estimated discount rate based upon recent observable debt security issuances with similar characteristics.

Loans Held for Sale

Loans held for sale consist of fixed-rate and adjustable-rate residential real estate loans intended for sale. Loans held for sale are stated at lower of cost or fair value. Fair value is determined based on prevailing market prices for loans with similar characteristics or on sale contract prices.

Bank Loans

The fair values of mortgage loans and commercial loans were estimated using a discounted cash flow method, a form of the income approach. Discount rates were determined considering rates at which similar portfolios of loans would be made under current conditions and considering liquidity spreads applicable to each loan portfolio based on the secondary market.

Financial Liabilities

Securities Sold Under Agreements to Repurchase

Securities sold under agreements to repurchase are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. The carrying values at December 31, 2018 and 2017 approximate fair value due to the short-term nature.

Bank Deposits

The fair value for demand deposits is equal to the amount payable on demand at the reporting date (that is, their carrying amounts). The carrying amounts of variable-rate money-market and savings accounts approximate their fair values at the reporting date as these are short-term in nature. The fair value of other interest-bearing deposits, including certificates of deposit, was calculated by discounting the future cash flows using discount rates based on the expected current market rates for similar products with similar remaining terms.

Borrowings

The carrying amount of borrowings approximates fair value due to the relative short-term nature of such borrowings. In addition, Stifel Bancorp’s Federal Home Loan Bank advances reflect terms that approximate current market rates for similar borrowings.

Senior Notes

The fair value of our senior notes is estimated based upon quoted market prices.

Debentures to Stifel Financial Capital Trusts

The fair value of our trust preferred securities is based on the discounted value of contractual cash flows. We have assumed a discount rate based on similar type debt instruments.

These fair value disclosures represent our best estimates based on relevant market information and information about the financial instruments. Fair value estimates are based on judgments regarding future expected losses, current economic conditions, risk characteristics of the various instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in the above methodologies and assumptions could significantly affect the estimates.

At December 31, 2018 and 2017, financial instruments owned in the amount of $669.0 million and $810.3 million, respectively, were pledged as collateral (on a settlement-date basis) for our repurchase agreements and short-term borrowings. Our financial instruments owned are presented on a trade-date basis in the consolidated statements of financial condition.

Financial instruments sold, but not yet purchased, represent obligations of our company to deliver the specified security at the contracted price, thereby creating a liability to purchase the security in the market at prevailing prices in future periods. We are obligated to acquire the securities sold short at prevailing market prices in future periods, which may exceed the amount reflected in the consolidated statements of financial condition.

At December 31, 2018, the amortized cost of 258 securities classified as available for sale exceeded their fair value by $55.9 million, of which $33.9 million related to investment securities that had been in a loss position for 12 months or longer. The total fair value of these investments at December 31, 2018, was $2.6 billion, which was 85.5% of our available-for-sale portfolio.

At December 31, 2018, the carrying value of 196 securities held to maturity exceeded their fair value by $102.0 million, of which $30.2 million related to securities held to maturity that have been in a loss position for 12 months or longer. As discussed in more detail below, we conduct periodic reviews of all securities with unrealized losses to assess whether the impairment is other-than-temporary.

Other-Than-Temporary Impairment

We evaluate all securities in an unrealized loss position quarterly to assess whether the impairment is other-than-temporary. Our OTTI assessment is a subjective process requiring the use of judgments and assumptions. There was no credit-related OTTI recognized during the years ended December 31, 2018, 2017, and 2016.

We believe the gross unrealized losses of $157.9 million related to our investment portfolio, as of December 31, 2018, are attributable to changes in market interest rates. We, therefore, do not expect to incur any credit losses related to these securities. In addition, we have no intent to sell these securities with unrealized losses, and it is not more likely than not that we will be required to sell these securities prior to recovery of the amortized cost. Accordingly, we have concluded that the impairment on these securities is not other-than-temporary.

In determining the amount of our allowance, we rely on an analysis of our loan portfolio, our experience, and our evaluation of general economic conditions. If our assumptions prove to be incorrect, our current allowance may not be sufficient to cover future loan losses and we may experience significant increases to our provision.

There are two components of the allowance for loan losses: the inherent allowance component and the specific allowance component. The inherent allowance component of the allowance for loan losses is used to estimate the probable losses inherent in the loan portfolio and includes non-homogeneous loans that have not been identified as impaired and portfolios of smaller balance homogeneous loans. Our company maintains methodologies by loan product for calculating an allowance for loan losses that estimates the inherent losses in the loan portfolio. Qualitative and environmental factors, such as economic and business conditions, nature and volume of the portfolio and lending terms, and volume and severity of past due loans may also be considered in the calculations. The allowance for loan losses is maintained at a level reasonable to ensure that it can adequately absorb the estimated probable losses inherent in the portfolio.

The specific allowance component of the allowance for loan losses is used to estimate probable losses for non-homogeneous exposures, including loans modified in a Troubled Debt Restructuring (TDR), which have been specifically identified for impairment analysis by our company and determined to be impaired. At December 31, 2018, we had $24.4 million of impaired loans, net of discounts, which included $9.1 million in troubled debt restructurings. The specific allowance on impaired loans at December 31, 2018 was $8.7 million. At December 31, 2017, we had $29.2 million of impaired loans, net of discounts, which included $9.1 million in troubled debt restructurings. The specific allowance on impaired loans at December 31, 2017 was $9.1 million. The gross interest income related to impaired loans, which would have been recorded had these loans been current in accordance with their original terms, and the interest income recognized on these loans during the year ended December 31, 2018 and 2017, were insignificant to the consolidated financial statements.

Credit quality indicators

As of December 31, 2018, bank loans were primarily extended to non-investment-grade borrowers. Substantially all of these loans align with the U.S. federal bank regulatory agencies’ definition of Pass. Loans meet the definition of Pass when they are performing and/or do not demonstrate adverse characteristics that are likely to result in a credit loss. A loan is determined to be impaired when principal or interest becomes 90 days past due or when collection becomes uncertain. At the time a loan is determined to be impaired, the accrual of interest and amortization of deferred loan origination fees is discontinued (non-accrual status), and any accrued and unpaid interest income is reversed.

We closely monitor economic conditions and loan performance trends to manage and evaluate our exposure to credit risk. Trends in delinquency ratios are an indicator, among other considerations, of credit risk within our loan portfolios. The level of nonperforming assets represents another indicator of the potential for future credit losses. Accordingly, key metrics we track and use in evaluating the credit quality of our loan portfolio include delinquency and nonperforming asset rates, as well as charge-off rates and our internal risk ratings of the loan portfolio. In general, we are a secured lender. At December 31, 2018 and 2017, 98.4% and 97.2% of our loan portfolio was collateralized, respectively. Collateral is required in accordance with the normal credit evaluation process based upon the creditworthiness of the customer and the credit risk associated with the particular transaction. Our company uses the following definitions for risk ratings:

Pass. A credit exposure rated pass has a continued expectation of timely repayment, all obligations of the borrower are current, and the obligor complies with material terms and conditions of the lending agreement.

Special Mention. Extensions of credit that have potential weakness that deserve management’s close attention and, if left uncorrected, may, at some future date, result in the deterioration of the repayment prospects or collateral position.

Substandard. Obligor has a well-defined weakness that jeopardizes the repayment of the debt and has a high probability of payment default with the distinct possibility that we will sustain some loss if noted deficiencies are not corrected.

Doubtful. Inherent weakness in the exposure makes the collection or repayment in full, based on existing facts, conditions, and circumstances, highly improbable, and the amount of loss is uncertain.

Doubtful loans are considered impaired. Substandard loans are regularly reviewed for impairment. When a loan is impaired, the impairment is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, or as a practical expedient, the observable market price of the loan or the fair value of the collateral if the loan is collateral dependent.

Portfolio segments:

Real Estate. Real estate loans include commercial real estate, residential real estate non-conforming loans, residential real estate conforming loans and home equity lines of credit. The allowance methodology related to real estate loans considers several factors, including, but not limited to, loan-to-value ratio, FICO score, home price index, delinquency status, credit limits, and utilization rates.

Commercial and industrial (“C&I”). C&I loans primarily include commercial and industrial lending used for general corporate purposes, working capital and liquidity, and “event-driven." “Event-driven” loans support client merger, acquisition or recapitalization activities. C&I lending is structured as revolving lines of credit, letter of credit facilities, term loans and bridge loans. Risk factors considered in determining the allowance for corporate loans include the borrower’s financial strength, seniority of the loan, collateral type, leverage, volatility of collateral value, debt cushion, and covenants.

Securities-based loans. Securities-based loans allow clients to borrow money against the value of qualifying securities for any suitable purpose other than purchasing, trading, or carrying securities or refinancing margin debt. The majority of consumer loans are structured as revolving lines of credit and letter of credit facilities and are primarily offered through Stifel’s Pledged Asset ("SPA") program. The allowance methodology for securities-based lending considers the collateral type underlying the loan, including the liquidity and trading volume of the collateral, position concentration and other borrower specific factors such as personal guarantees.

Construction and land. Short-term loans used to finance the development of a real estate project.

Other. Other loans includes consumer, credit card, and indirect lending.

On March 19, 2018, the Company completed the acquisition of Ziegler. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $19.0 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management and Institutional Group segments. Identifiable intangible assets purchased by our company consisted of customer relationships and non-compete agreements with an acquisition-date fair value of $9.5 million. See Note 3 in the notes to our consolidated financial statements for additional information regarding the acquisition of Ziegler.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the Ziegler business and of the hired financial advisors and the conversion of the customer accounts to our platform. Goodwill is expected to be deductible for federal income tax purposes.

On August 31, 2018, the Company completed the acquisition of BBI. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $38.4 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management segment. Identifiable intangible assets purchased by our company consisted of core deposits with an acquisition-date fair value of $8.6 million. The allocation of the purchase price of BBI is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets of BBI as of the acquisition date and the identified intangible assets. The final goodwill recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments and the recording of identified intangible assets. See Note 3 in the notes to our consolidated financial statements for additional information regarding the acquisition of BBI.

On October 1, 2018, the Company completed the acquisition of Rand. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $8.3 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management segment. Identifiable intangible assets purchased by our company consisted of customer relationships with an acquisition-date fair value of $4.6 million. The allocation of the purchase price of Rand is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets of Rand as of the acquisition date and the identified intangible assets. The final goodwill recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments and the recording of identified intangible assets. See Note 3 in the notes to our consolidated financial statements for additional information regarding the acquisition of Rand.

The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the Rand business and of the hired financial advisors and the conversion of the customer accounts to our platform.

Borrowings and Federal Home Loan Bank Advances

NOTE 11 – Borrowings and Federal Home Loan Bank Advances

Our short-term financing is generally obtained through short-term bank line financing on an uncommitted, secured basis, advances from the Federal Home Loan Bank, and securities lending arrangements. We borrow from various banks on a demand basis with company-owned and customer securities pledged as collateral. The value of customer-owned securities used as collateral is not reflected in the consolidated statements of financial condition. We also have an unsecured, committed bank line available.

Our uncommitted secured lines of credit at December 31, 2018, totaled $1.0 billion with six banks and are dependent on having appropriate collateral, as determined by the bank agreements, to secure an advance under the line. The availability of our uncommitted lines is subject to approval by the individual banks each time an advance is requested and may be denied. Our peak daily borrowing on our uncommitted secured lines was $391.0 million during the year ended December 31, 2018. There are no compensating balance requirements under these arrangements. Any borrowings on secured lines of credit are generally utilized to finance certain fixed income securities. At December 31, 2018, our uncommitted secured lines of credit of $56.0 million are included in borrowings in the consolidated statements of financial condition. Our uncommitted secured lines were collateralized by company-owned securities valued at $63.0 million at December 31, 2018.

The Federal Home Loan advances of $540.0 million as of December 31, 2018, are floating-rate advances. The weighted average interest rates on these advances during the year ended December 31, 2018, was 1.61%. The advances are secured by Stifel Bancorp’s residential mortgage loan portfolio and investment portfolio. The interest rates reset on a daily basis. Stifel Bancorp has the option to prepay these advances without penalty on the interest reset date.

Our committed bank line financing at December 31, 2018, consisted of a $200.0 million revolving credit facility. The credit facility expires in March 2020. The applicable interest rate under the revolving credit facility is calculated as a per annum rate equal to the London Interbank Offered Rate (“LIBOR”) plus 2.00%, as defined in the revolving credit facility. At December 31, 2018, we had no advances on our revolving credit facility and were in compliance with all covenants.

In June 2018, Stifel, our broker-dealer subsidiary, entered into a 364-day Credit Agreement (“Stifel Credit Facility”) with a maturity date of June 2019 in which the lenders are a number of financial institutions. This committed unsecured borrowing facility provides for maximum borrowings of up to $250.0 million at variable rates of interest. At December 31, 2018, we had no advances on the Stifel Credit Facility and were in compliance with all covenants.

As of December 31, 2018, a subsidiary of Stifel Bancorp was a party to two Notes. The Notes mature in 2043. The Notes bear interest contractually at fixed rates as per the Note Purchase Agreement. The outstanding balance on the Notes at December 31, 2018 was $124.5 million and is included in borrowings in the consolidated statements of financial condition.

Derivative Instruments And Hedging Activities

General Discussion Of Derivative Instruments And Hedging Activities [Abstract]

Derivative Instruments And Hedging Activities

NOTE 14 – Derivative Instruments and Hedging Activities

We use interest rate swaps as part of our interest rate risk management strategy. Interest rate swaps generally involve the exchange of fixed and variable rate interest payments between two parties, based on a common notional principal amount and maturity date with no exchange of underlying principal amounts. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for our company making fixed payments. Our policy is not to offset fair value amounts recognized for derivative instruments and fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral arising from derivative instruments recognized at fair value executed with the same counterparty under master netting arrangements.

The following table provides the notional values and fair values of our derivative instruments as of December 31, 2018 and 2017 (in thousands):

	December 31, 2018
	Asset Derivatives
	Notional Value		Balance Sheet Location	Fair Value
Derivatives designated as hedging instruments under Topic 815:
Cash flow interest rate contracts	$	540,000	Other assets	$	7,683

	Asset Derivatives
	Notional Value		Balance Sheet Location	Fair Value
Derivatives designated as hedging instruments under Topic 815:
Cash flow interest rate contracts	$	540,000	Other assets	$	7,995

Cash Flow Hedges

We have entered into interest rate swap agreements that effectively modify our exposure to interest rate risk by converting floating rate debt to a fixed rate debt. The swaps have an average remaining life of 1.1 years.

Any unrealized gains or losses related to cash flow hedging instruments are reclassified from accumulated other comprehensive loss into earnings in the same period the hedged forecasted transaction affects earnings and are recorded in interest expense in the consolidated statements of operations. The ineffective portion of the cash flow hedging instruments is recorded in other income or other operating expense in the consolidated statements of operations.

Amounts reported in accumulated other comprehensive loss related to derivatives will be reclassified to interest expense as interest payments are made on our variable rate deposits. During the next twelve months, we estimate that $3.9 million will be reclassified as an increase to interest expense.

The following table shows the effect of our company’s derivative instruments in the consolidated statements of operations for the years ended December 31, 2018, 2017, and 2016 (in thousands):

	Year Ended December 31, 2018
	Gain/(Loss) Recognized in OCI (Effectiveness)			Location of Loss Reclassified From OCI Into Income	Gain/(Loss) Reclassified From OCI Into Income		Location of Loss Recognized in OCI (Ineffectiveness)	Loss Recognized Due to Ineffectiveness

Cash flow interest rate contracts	$	6,383	Interest expense	$	(5,444	)	Interest expense	$	30

We maintain a risk management strategy that incorporates the use of derivative instruments to minimize significant unplanned fluctuations in earnings caused by interest rate volatility. Our goal is to manage sensitivity to changes in rates by hedging the maturity characteristics of variable rate affiliated deposits, thereby limiting the impact on earnings. By using derivative instruments, we are exposed to credit and market risk on those derivative positions. We manage the market risk associated with interest rate contracts by establishing and monitoring limits as to the types and degree of risk that may be undertaken. Credit risk is equal to the extent of the fair value gain in a derivative if the counterparty fails to perform. When the fair value of a derivative contract is positive, this generally indicates that the counterparty owes our company and, therefore, creates a repayment risk for our company. When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, have no repayment risk. See Note 5 in the notes to our consolidated financial statements for further discussion on how we determine the fair value of our financial instruments. We minimize the credit (or repayment) risk in derivative instruments by entering into transactions with high-quality counterparties that are reviewed periodically by senior management.

Credit Risk-Related Contingency Features

We have agreements with our derivative counterparties containing provisions where if we default on any of our indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then we could also be declared in default on our derivative obligations.

We have agreements with certain of our derivative counterparties that contain provisions where if our shareholders’ equity declines below a specified threshold or if we fail to maintain a specified minimum shareholders’ equity, then we could be declared in default on our derivative obligations.

Certain of our agreements with our derivative counterparties contain provisions where if a specified event or condition occurs that materially changes our creditworthiness in an adverse manner, we may be required to fully collateralize our obligations under the derivative instrument.

Regulatory Capital-Related Contingency Features

Certain of our derivative instruments contain provisions that require us to maintain our capital adequacy requirements. If we were to lose our status as “adequately capitalized,” we would be in violation of those provisions, and the counterparties of the derivative instruments could request immediate payment or demand immediate and ongoing full overnight collateralization on derivative instruments in net liability positions.

Counterparty Risk

In the event of counterparty default, our economic loss may be higher than the uncollateralized exposure of our derivatives if we were not able to replace the defaulted derivatives in a timely fashion. We monitor the risk that our uncollateralized exposure to each of our counterparties for interest rate swaps will increase under certain adverse market conditions by performing periodic market stress tests. These tests evaluate the potential additional uncollateralized exposure we would have to each of these derivative counterparties assuming changes in the level of market rates over a brief time period.

Commitments, Guarantees, And Contingencies

NOTE 17 – Commitments, Guarantees, and Contingencies

Broker-Dealer Commitments and Guarantees

In the normal course of business, we enter into underwriting commitments. Settlement of transactions relating to such underwriting commitments, which were open at December 31, 2018, had no material effect on the consolidated financial statements.

We also provide guarantees to securities clearinghouses and exchanges under their standard membership agreement, which requires members to guarantee the performance of other members. Under the agreement, if another member becomes unable to satisfy its obligations to the clearinghouse, other members would be required to meet shortfalls. Our liability under these agreements is not quantifiable and may exceed the cash and securities we have posted as collateral. However, the potential requirement for us to make payments under these arrangements is considered remote. Accordingly, no liability has been recognized for these arrangements.

Other Commitments

In the ordinary course of business, Stifel Bancorp has commitments to extend credit in the form of commitments to originate loans, standby letters of credit, and lines of credit. See Note 23 in the notes to consolidated financial statements for further details.

We have committed capital to certain entities, and these commitments generally have no specified call dates. We had $2.5 million of commitments outstanding at December 31, 2018.

Concentration of Credit Risk

We provide investment, capital-raising, and related services to a diverse group of domestic customers, including governments, corporations, and institutional and individual investors. Our exposure to credit risk associated with the non-performance of customers in fulfilling their contractual obligations pursuant to securities transactions can be directly impacted by volatile securities markets, credit markets, and regulatory changes. This exposure is measured on an individual customer basis and on a group basis for customers that share similar attributes. To reduce the potential for risk concentrations, counterparty credit limits have been implemented for certain products and are continually monitored in light of changing customer and market conditions. As of December 31, 2018 and 2017, we did not have significant concentrations of credit risk with any one customer or counterparty, or any group of customers or counterparties.

Operating Leases

Future minimum commitments under non-cancelable operating leases at December 31, 2018, are as follows (in thousands):

2019	$	89,887
2020		81,899
2021		66,887
2022		59,353
2023		50,916
Thereafter		107,678
	$	456,620

Certain leases contain provisions for renewal options and escalation clauses based on increases in certain costs incurred by the lessor. We amortize office lease incentives and rent escalation on a straight-line basis over the life of the lease. Rent expense for the years ended December 31, 2018, 2017, and 2016, included in occupancy and equipment rental in the consolidated statements of operations, was $104.6 million, $104.5 million, and $108.7 million, net of sublease income.

Loss Contingency Information About Litigation Matters [Abstract]

Legal Proceedings

NOTE 18 – Legal Proceedings

Our company and its subsidiaries are named in and subject to various proceedings and claims arising primarily from our securities business activities, including lawsuits, arbitration claims, class actions, and regulatory matters. Some of these claims seek substantial compensatory, punitive, or indeterminate damages. Our company and its subsidiaries are also involved in other reviews, investigations, and proceedings by governmental and self-regulatory organizations regarding our business, which may result in adverse judgments, settlements, fines, penalties, injunctions, and other relief. We are contesting allegations in these claims, and we believe that there are meritorious defenses in each of these lawsuits, arbitrations, and regulatory investigations. In view of the number and diversity of claims against our company, the number of jurisdictions in which litigation is pending, and the inherent difficulty of predicting the outcome of litigation and other claims, we cannot state with certainty what the eventual outcome of pending litigation or other claims will be.

We have established reserves for potential losses that are probable and reasonably estimable that may result from pending and potential legal actions, investigations, and regulatory proceedings. In many cases, however, it is inherently difficult to determine whether any loss is probable or reasonably possible or to estimate the amount or range of any potential loss, particularly where proceedings may be in relatively early stages or where plaintiffs are seeking substantial or indeterminate damages. Matters frequently need to be more developed before a loss or range of loss can reasonably be estimated.

In our opinion, based on currently available information, review with outside legal counsel, and consideration of amounts provided for in our consolidated financial statements with respect to these matters the ultimate resolution of these matters will not have a material adverse impact on our financial position and results of operations. However, resolution of one or more of these matters may have a material effect on the results of operations in any future period, depending upon the ultimate resolution of those matters and depending upon the level of income for such period. For matters where a reserve has not been established and for which we believe a loss is reasonably possible, as well as for matters where a reserve has been recorded but for which an exposure to loss in excess of the amount accrued is reasonably possible, based on currently available information, we believe that such losses will not have a material effect on our consolidated financial statements.

Regulatory Capital Requirements [Abstract]

Regulatory Capital Requirements

NOTE 19 – Regulatory Capital Requirements

We operate in a highly regulated environment and are subject to capital requirements, which may limit distributions to our company from its subsidiaries. Distributions from our broker-dealer subsidiaries are subject to net capital rules. A broker-dealer that fails to comply with the SEC’s Uniform Net Capital Rule (Rule 15c3-1) may be subject to disciplinary actions by the SEC and self-regulatory organizations, such as FINRA, including censures, fines, suspension, or expulsion. Stifel has chosen to calculate its net capital under the alternative method, which prescribes that their net capital shall not be less than the greater of $1.0 million or two percent of aggregate debit balances (primarily receivables from customers) computed in accordance with the SEC’s Customer Protection Rule (Rule 15c3-3). Our other broker-dealer subsidiaries calculate their net capital under the aggregate indebtedness method, whereby their aggregate indebtedness may not be greater than fifteen times their net capital (as defined).

At December 31, 2018, Stifel had net capital of $342.7 million, which was 20.9% of aggregate debit items and $310.0 million in excess of its minimum required net capital. At December 31, 2018, all of our other broker-dealer subsidiaries’ net capital exceeded the minimum net capital required under the SEC rule.

Our international subsidiary is subject to the regulatory supervision and requirements of the Financial Conduct Authority (“FCA”) in the United Kingdom. At December 31, 2018, our international subsidiary’s capital and reserves were in excess of the financial resources requirement under the rules of the FCA.

Our company, as a bank holding company, Stifel Bank & Trust, and Stifel Bank (“bank subsidiaries”) are subject to various regulatory capital requirements administered by the Federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our company’s and its bank subsidiaries’ financial results. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, our company and its bank subsidiaries must meet specific capital guidelines that involve quantitative measures of our assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. Our company’s and its bank subsidiaries’ capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Under the Basel III rules, the quantity and quality of regulatory capital increases, a capital conservation buffer was established, selected changes were made to the calculation of risk-weighted assets, and a new ratio, common equity Tier 1 was introduced, all of which are applicable to both our company and its bank subsidiaries’. Various aspects of Basel III will be subject to multi-year transition periods through December 31, 2018.

Our company and its bank subsidiaries are required to maintain minimum amounts and ratios of Total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), Tier 1 capital to average assets (as defined), and under rules defined in Basel III, Common equity Tier 1 capital to risk-weighted assets. Our company and its bank subsidiaries each calculate these ratios in order to assess compliance with both regulatory requirements and their internal capital policies. At current capital levels, our company and its bank subsidiaries are each categorized as “well capitalized” under the regulatory framework for prompt corrective action.

To be categorized as “well capitalized,” our company and its bank subsidiaries must maintain total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the tables below (in thousands, except ratios).

Revenues from Contracts with Customers

NOTE 20 – Revenues from Contracts with Customers

The following table presents the Company’s total revenues separated between revenues from contracts with customers and other sources of revenues for the year ended December 31, 2018 (in thousands):

	Year Ended December 31, 2018
Revenues from contracts with customers:
Commissions	$	657,732
Investment banking		707,670
Asset management and service fees		806,175
Other		15,568
Total revenue from contracts with customers		2,187,145
Other sources of revenue:
Interest		646,449
Principal transactions		351,378
Other		9,985
Total revenues	$	3,194,957

Revenue from contracts with customers is recognized when, or as, we satisfy our performance obligations by transferring the promised goods or services to the customers. A good or service is transferred to a customer when, or as, the customer obtains control of that good or service. A performance obligation may be satisfied over time or at a point in time. Revenue from a performance obligation satisfied over time is recognized by measuring our progress in satisfying the performance obligation in a manner that depicts the transfer of the goods or services to the customer. Revenue from a performance obligation satisfied at a point in time is recognized at the point in time that we determine the customer obtains control over the promised good or service. The amount of revenue recognized reflects the consideration we expect to be entitled to in exchange for those promised goods or services (i.e., the “transaction price”). In determining the transaction price, we consider multiple factors, including the effects of variable consideration. Variable consideration is included in the transaction price only to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainties with respect to the amount are resolved. In determining when to include variable consideration in the transaction price, we consider the range of possible outcomes, the predictive value of our past experiences, the time period of when uncertainties expect to be resolved and the amount of consideration that is susceptible to factors outside of our influence, such as market volatility or the judgment and actions of third parties.

The following provides detailed information on the recognition of our revenues from contracts with customers:

Commissions. We earn commission revenue by executing, settling, and clearing transactions for clients primarily in OTC and listed equity securities, insurance products, and options. Trade execution and clearing and custody services, when provided together, represent a single performance obligation as the services are not separately identifiable in the context of the contract. Commission revenues associated with combined trade execution and clearing and custody services, as well as trade execution services on a standalone basis, are recognized at a point in time on trade-date. Commission revenues are generally paid on settlement date and we record a receivable between trade-date and payment on settlement date.

Investment Banking. We provide our clients with a full range of capital markets and financial advisory services. Capital markets services include underwriting and placement agent services in both the equity and debt capital markets, including private equity placements, initial public offerings, follow-on offerings, underwriting and distributing public and private debt.

Capital raising revenues are recognized at a point in time on trade-date, as the client obtains the control and benefit of the capital markets offering at that point. Costs associated with capital raising transactions are deferred until the related revenue is recognized or the engagement is otherwise concluded, and are recorded on a gross basis within other operating expenses in the consolidated statements of operations as we are acting as a principal in the arrangement. Any expenses reimbursed by our clients are recognized as investment banking revenues.

Revenues from financial advisory services primarily consist of fees generated in connection with merger, acquisition and restructuring transactions. 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. Fees received prior to the completion of the transaction are deferred within accounts payable and accrued expenses on the consolidated statements of financial condition. Advisory fees from restructuring engagements are recognized over time using a time elapsed measure of progress as our clients simultaneously receive and consume the benefits of those services as they are provided. A significant portion of the fees we receive for our advisory services are considered variable as they are contingent upon a future event (e.g., completion of a transaction or third party emergence from bankruptcy) and are excluded from the transaction price until the uncertainty associated with the variable consideration is subsequently resolved, which is expected to occur upon achievement of the specified milestone. Payment for advisory services are generally due promptly upon completion of a specified milestone or, for retainer fees, periodically over the course of the engagement. We recognize a receivable between the date of completion of the milestone and payment by the customer. Expenses associated with investment banking advisory engagements are deferred only to the extent they are explicitly reimbursable by the client and the related revenue is recognized upon completion of services. All other investment banking advisory related expenses, including expenses incurred related to restructuring assignments, are expensed as incurred. All investment banking advisory expenses are recognized within other operating expenses in the consolidated statements of operations and any expenses reimbursed by our clients are recognized as investment banking revenues.

Asset Management Fees. We earn management and performance fees in connection with investment advisory services provided to institutional and individual clients. Investment advisory fees are charged based on the value of assets in fee-based accounts and are affected by changes in the balances of client assets due to market fluctuations and levels of net new client assets. Fees are charged either in advance based on fixed rates applied to the value of the customers’ account at the beginning of the period or periodically based on contracted rates and account performance. Contracts can be terminated at any time with no incremental payments due to our company upon termination. If the contract is terminated by the customer fees are prorated for the period and fees charged for the post termination period are refundable to the customer.

See Note 25 for further break-out of revenues by geography.

Information on Remaining Performance Obligations and Revenue Recognized from Past Performance

We do not disclose information about remaining performance obligations pertaining to contracts that have an original expected duration of one year or less. The transaction price allocated to remaining unsatisfied or partially unsatisfied performance obligations with an original expected duration exceeding one year was not material at December 31, 2018. Investment banking advisory fees that are contingent upon completion of a specific milestone and fees associated with certain distribution services are also excluded as the fees are considered variable and not included in the transaction price at December 31, 2018.

Contract Balances

The timing of our revenue recognition may differ from the timing of payment by our customers. We record a receivable when revenue is recognized prior to payment and we have an unconditional right to payment. Alternatively, when payment precedes the provision of the related services, we record deferred revenue until the performance obligations are satisfied.

We had receivables related to revenues from contracts with customers of $116.7 million and $93.0 million at December 31, 2018 and December 31, 2017, respectively, in other assets in the consolidated statements of financial condition. We had no significant impairments related to these receivables during the year ended December 31, 2018.

Our deferred revenue primarily relates to retainer fees received in investment banking advisory engagements where the performance obligation has not yet been satisfied. Deferred revenue at December 31, 2018 was $9.5 million and included in accounts payable and accrued expenses in the consolidated statements of financial condition.

Employee Incentive, Deferred Compensation, And Retirement Plans

Share Based Compensation Allocation And Classification In Financial Statements [Abstract]

Employee Incentive, Deferred Compensation, And Retirement Plans

NOTE 22 – Employee Incentive, Deferred Compensation, and Retirement Plans

We maintain several incentive stock award plans that provide for the granting of stock options, stock appreciation rights, restricted stock, performance award, stock units, and debentures to our employees. We are permitted to issue new shares under all stock award plans approved by shareholders or to reissue our treasury shares. Awards under our company’s incentive stock award plans are granted at market value at the date of grant. The awards generally vest ratably over a one- to ten-year vesting period.

All stock-based compensation plans are administered by the Compensation Committee of the Board of Directors (“Compensation Committee”), which has the authority to interpret the plans, determine to whom awards may be granted under the plans, and determine the terms of each award. According to these plans, we are authorized to grant an additional 5.2 million shares at December 31, 2018.

Stock-based compensation expense included in compensation and benefits in the consolidated statements of operations for our company’s incentive stock award plans was $111.8 million, $246.7 million, and $190.1 million for the years ended December 31, 2018, 2017, and 2016, respectively.

The tax benefit related to stock-based compensation recognized in shareholders’ equity was $4.0 million for the year ended December 31, 2018. As a result of the adoption of a new accounting standard on January 1, 2017, we recognized an excess tax benefit from stock-based compensation of $64.7 million for the year ended December 31, 2017. We adopted the new guidance prospectively. The tax provision related to stock-based compensation recognized in shareholders’ equity was $4.9 million for the year ended December 31, 2016.

In response to the Tax Legislation that was enacted in December 2017, the Company offered certain employees the opportunity to participate in the conversion of certain restricted stock units into restricted stock pursuant to a Modification Award Agreement. Under the terms of the Modification Award Agreement, vesting of certain restricted stock will no longer be contingent upon continued employment but rather will vest so long as the employee is not engaged in certain competitive or soliciting activities as provided in the Wealth Accumulation Plan (the “Plan”). The conversion through acceptance of the Modification Agreement by the participating employees resulted in a charge of $55.9 million, which is included in compensation and benefits in the consolidated statement of operations for the year ended December 31, 2017.  The fair value of these awards was based upon the closing price of our company’s common stock on the date of the grant of the awards.

In December 2017, the Company accelerated the vesting of certain outstanding debenture awards, resulting in a charge of $51.4 million, which is included in compensation and benefits in the consolidated statement of operations for the year ended December 31, 2017.

During 2016, the Company’s Board of Directors removed the continuing service requirements associated with restricted stock units that were granted to certain employees of Barclays in December 2015. As a result of the modification, the awards were expensed at date of modification, resulting in a charge of $58.6 million during 2016. The fair value of the awards is based upon the closing price of our company’s common stock on the date of the grant of the awards. These charges are included in compensation and benefits in the consolidated statements of operations for the year ended December 31, 2016.

Stock Options

We have substantially eliminated the use of stock options as a form of compensation. During the year ended December 31, 2018, no options were granted.

The total intrinsic value of options exercised during the years ended December 31, 2018, 2017 and 2016 were not material. Cash proceeds from the exercise of stock options were not material for the years ended December 31, 2018, 2017, and 2016.

Restricted Stock Units and Restricted Stock Awards

A restricted stock unit represents the right to receive a share of common stock from our company at a designated time in the future without cash payment by the employee and is issued in lieu of cash incentive, principally for deferred compensation and employee retention plans. The restricted stock units vest on an annual basis over the next one to ten years and are distributable, if vested, at future specified dates. Restricted stock awards are restricted as to sale or disposition. These restrictions lapse over the next one to five years.

Our company grants Performance-based Restricted Stock Units (“PRSUs”) to its executive officers. Under the terms of the grants, the number of PRSUs that will vest and convert to shares will be based on our company's achievement of the pre-determined performance objectives during the performance period. The PRSUs will be measured over a four-year performance period and vested over a five-year period. The number of shares converted has the potential to range from 0% to 200% based on how our company performs during the performance period. Compensation expense is amortized on a straight-line basis over the service period based on the fair value of the award on the grant date. The Company’s pre-determined performance objectives must be met for the awards to vest. Employees forfeit unvested share units upon termination of employment with a corresponding reversal of compensation expense. At December 31, 2018, the total number of restricted stock units and restricted stock awards outstanding was 16.4 million, of which 14.1 million were unvested. At December 31, 2018, the total number of PRSU’s was 0.7 million, of which all were unvested.

A summary of unvested restricted equity award activity, which includes restricted stock units and restricted stock awards, for the year ended December 31, 2018 is presented below (in thousands, except weighted-average fair value):

	Units			Weighted-average grant date fair value
Unvested December 31, 2017		13,938		$	44.31
Granted		2,496			55.94
Vested		(2,030	)		41.18
Cancelled		(287	)		47.98
Unvested December 31, 2018		14,117		$	46.75

At December 31, 2018, there was approximately $297.4 million of unrecognized compensation cost for restricted stock units and restricted stock, which is expected to be recognized over a weighted-average period of 2.8 years. The fair value of restricted stock units and restricted stock that vested or converted during the year ended December 31, 2018, was $83.6 million.

Deferred Compensation Plans

The Wealth Accumulation Plan (the “Plan”) is provided to certain revenue producers, officers, and key administrative employees, whereby a certain percentage of their incentive compensation is deferred as defined by the Plan into company stock units and debentures. Participants may elect to defer a portion of their incentive compensation. Deferred awards generally vest over a one- to ten-year period and are distributable upon vesting or at future specified dates. Deferred compensation costs are amortized on a straight-line basis over the vesting period. Elective deferrals are 100% vested.

Additionally, the Plan allows Stifel financial advisors who achieve certain levels of production the option to defer a certain percentage of their gross commissions. As stipulated by the Plan, the financial advisors will defer 5% of their gross commissions. The mandatory deferral will be split evenly between company restricted stock units and a company fixed-rate cash debenture. They have the option to defer an additional 1% of gross commissions into company stock units with a 25% matching contribution

In addition, certain financial advisors, upon joining our company, may receive company stock units in lieu of transition cash payments. Deferred compensation related to these awards generally vests over a one- to eight-year period. Deferred compensation costs are amortized on a straight-line basis over the deferral period.

Employee Profit Sharing Plan

Eligible employees of our company who have met certain service requirements may participate in the Stifel Financial Corp. Profit Sharing 401(k) Plan (the “Plan”). Employees are permitted within limitations imposed by tax law to make pre-tax contributions to the Plan. We may match certain employee contributions or make additional contributions to the Plan at our discretion. Our contributions to the Profit Sharing Plan, included in compensation and benefits in the consolidated statements of operations, were $12.8 million, $7.1 million, and $6.5 million for the years ended December 31, 2018, 2017, and 2016, respectively.

Off-Balance Sheet Credit Risk

12 Months Ended

Dec. 31, 2018

Concentration Risks Types No Concentration Percentage [Abstract]

Off-Balance Sheet Credit Risk

NOTE 23 – Off-Balance Sheet Credit Risk

In the normal course of business, we execute, settle, and finance customer and proprietary securities transactions. These activities expose our company to off-balance sheet risk in the event that customers or other parties fail to satisfy their obligations.

In accordance with industry practice, securities transactions generally settle within two business days after trade date. Should a customer or broker fail to deliver cash or securities as agreed, we may be required to purchase or sell securities at unfavorable market prices.

We borrow and lend securities to facilitate the settlement process and finance transactions, utilizing customer margin securities held as collateral. We monitor the adequacy of collateral levels on a daily basis. We periodically borrow from banks on a collateralized basis, utilizing firm and customer margin securities in compliance with SEC rules. Should the counterparty fail to return customer securities pledged, we are subject to the risk of acquiring the securities at prevailing market prices in order to satisfy our customer obligations. We control our exposure to credit risk by continually monitoring our counterparties’ positions, and where deemed necessary, we may require a deposit of additional collateral and/or a reduction or diversification of positions. Our company sells securities it does not currently own (short sales) and is obligated to subsequently purchase such securities at prevailing market prices. We are exposed to risk of loss if securities prices increase prior to closing the transactions. We control our exposure to price risk from short sales through daily review and setting position and trading limits.

We manage our risks associated with the aforementioned transactions through position and credit limits and the continuous monitoring of collateral. Additional collateral is required from customers and other counterparties when appropriate.

We have accepted collateral in connection with resale agreements, securities borrowed transactions, and customer margin loans. Under many agreements, we are permitted to sell or repledge these securities held as collateral and use these securities to enter into securities lending arrangements or to deliver to counterparties to cover short positions. At December 31, 2018 and 2017, the fair value of securities accepted as collateral where we are permitted to sell or repledge the securities was $2.4 billion and $2.4 billion, respectively, and the fair value of the collateral that had been sold or repledged was $535.4 million and $233.7 million, respectively.

We enter into interest rate derivative contracts to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Our derivative financial instruments are principally used to manage differences in the amount, timing, and duration of our known or expected cash payments related to certain variable-rate affiliated deposits. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for us making fixed-rate payments. Our interest rate hedging strategies may not work in all market environments and, as a result, may not be effective in mitigating interest rate risk.

Derivatives’ notional contract amounts are not reflected as assets or liabilities in the consolidated statements of financial condition. Rather, the market or fair value of the derivative transactions are reported in the consolidated statements of financial condition as other assets or accounts payable and accrued expenses, as applicable.

For a complete discussion of our activities related to derivative instruments, see Note 14 in the notes to consolidated financial statements.

In the ordinary course of business, Stifel Bancorp has commitments to originate loans, standby letters of credit, and lines of credit. Commitments to originate loans are agreements to lend to a customer as long as there is no violation of any condition established by the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a portion of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash commitments. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if necessary, is based on the credit evaluation of the counterparty. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, commercial real estate, and residential real estate.

At December 31, 2018 and 2017, Stifel Bancorp had outstanding commitments to originate loans aggregating $146.7 million and $160.2 million, respectively. The commitments extended over varying periods of time, with all commitments at December 31, 2018, scheduled to be disbursed in the following three months.

Through Stifel Bancorp, in the normal course of business, we originate residential mortgage loans and sell them to investors. We may be required to repurchase mortgage loans that have been sold to investors in the event there are breaches of certain representations and warranties contained within the sales agreements. We may be required to repurchase mortgage loans that were sold to investors in the event that there was inadequate underwriting or fraud, or in the event that the loans become delinquent shortly after they are originated. We also may be required to indemnify certain purchasers and others against losses they incur in the event of breaches of representations and warranties and in various other circumstances, and the amount of such losses could exceed the repurchase amount of the related loans. Consequently, we may be exposed to credit risk associated with sold loans.

Standby letters of credit are irrevocable conditional commitments issued by Stifel Bancorp to guarantee the performance of a customer to a third party. Financial standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing, and similar transactions. Performance standby letters of credit are issued to guarantee performance of certain customers under non-financial contractual obligations. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loans to customers. Should Stifel Bancorp be obligated to perform under the standby letters of credit, it may seek recourse from the customer for reimbursement of amounts paid. At December 31, 2018 and 2017, Stifel Bancorp had outstanding letters of credit totaling $26.3 million and $82.5 million, respectively. A majority of the standby letters of credit commitments at December 31, 2018, have expiration terms that are less than one year.

Lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Lines of credit generally have fixed expiration dates. Stifel Bancorp uses the same credit policies in granting lines of credit as it does for on-balance sheet instruments. At December 31, 2018 and 2017, Stifel Bancorp had granted unused lines of credit to commercial and consumer borrowers aggregating $919.5 million and $590.5 million, respectively.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“Tax Legislation”) was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017.

In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which allows us to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. In accordance with SAB 118, we recorded an additional tax benefit of $3.0 million during 2018 for the re-measurement of certain deferred tax assets and liabilities based on the rates in which they are expected to reverse in the future. Our measurement of deferred tax taxes and our provisional analysis of the one-time repatriation transition tax is complete with no additional impact on current year earnings.

Our net deferred tax asset at December 31, 2018, includes net operating loss carryforwards of $308.1 million that expire between 2020 and 2038. Certain of our net operating loss carryforwards do not expire. A valuation allowance is recorded to the extent that it is more likely than not that any portion of the deferred tax asset will not be realized. The valuation allowance was decreased by $0.3 million. We believe the realization of the remaining net deferred tax asset of $112.0 million is more likely than not based on the ability to carry back losses against prior year taxable income for tax years before 2018 and carryforward net operating losses indefinitely after 2018, and expectations of future taxable income, which is supported by a history of cumulative income.

The current tax payable, included in accounts payable and accrued expenses, is $8.4 million and $4.2 million as of December 31, 2018 and 2017, respectively. At December 31, 2018, the Company did not have a tax receivable. At December 31, 2017, the Company had a tax receivable of $54.3 million, included in other assets, which is primarily attributable to tax deductions that the Company will realize as a result of the actions taken to maximize tax savings in response to the Tax Legislation that was enacted in the fourth quarter of 2017 and prior year tax overpayments.

As of December 31, 2018, we considered all undistributed earnings of non-U.S. subsidiaries to be permanently reinvested. Therefore, we have not provided for any U.S. deferred income taxes. Because the time or manner of repatriation is uncertain, we cannot determine the impact of local taxes, withholding taxes and foreign tax credits associated with the future repatriation of such earnings, and therefore cannot quantify the tax liability that would be payable in the event all such foreign earnings are repatriated.

Uncertain Tax Positions

As of December 31, 2018 and 2017, we had $0.3 million and $3.2 million, respectively, of gross unrecognized tax benefits, all of which, if recognized, would impact the effective tax rate. We recognize interest and penalties related to uncertain tax positions in provision for income taxes in the consolidated statements of operations. As of December 31, 2018 and 2017, we had accrued interest and penalties of $0.1 million and $0.5 million, respectively, before benefit of federal tax deduction, included in accounts payable and accrued expenses in our consolidated statements of financial condition. The amount of interest and penalties recognized in our consolidated statements of operations for the years ended December 31, 2018, 2017, and 2016, was not significant.

The following table summarizes the activity related to our company’s unrecognized tax benefits from January 1, 2016 to December 31, 2018 (in thousands): 

	Year Ended December 31,
	2018			2017			2016

Ending balance	$	312		$	3,180		$	1,800

We file income tax returns with the U.S. federal jurisdiction, various states, and certain foreign jurisdictions. We are not subject to U.S. federal examination for taxable years before 2013. We are not subject to certain state and local, or non-U.S. income tax examinations for taxable years before 2010.

There is a reasonable possibility that the unrecognized tax benefits will change within the next 12 months as a result of the expiration of various statutes of limitations or for the resolution of U.S. federal and state examinations, but we do not expect this change to be material to the consolidated financial statements.

Segment Reporting [Abstract]

Segment Reporting

NOTE 25 – Segment Reporting

We currently operate through the following three reporting segments: Global Wealth Management, Institutional Group, and various corporate activities combined in the Other segment.

Our Global Wealth Management segment consists of two operating segments, the Private Client Group and Stifel Bancorp. The Private Client Group includes branch offices and independent contractor offices of our broker-dealer subsidiaries located throughout the United States. These branches provide securities brokerage services, including the sale of equities, mutual funds, fixed income products, and insurance, as well as offering banking products to their clients through our bank subsidiaries, which provide residential, consumer, and commercial lending, as well as FDIC-insured deposit accounts to customers of our private client group and to the general public.

The Institutional Group segment includes institutional sales and trading. It provides securities brokerage, trading, and research services to institutions, with an emphasis on the sale of equity and fixed income products. This segment also includes the management of and participation in underwritings for both corporate and public finance (exclusive of sales credits generated through the private client group, which are included in the Global Wealth Management segment), merger and acquisition, and financial advisory services.

The Other segment includes interest income from stock borrow activities, unallocated interest expense, interest income and gains and losses from investments held, compensation expense associated with the expensing of restricted stock awards with no continuing service requirements in conjunction with recent acquisitions and the actions taken by the Company in response to the Tax Regulation enacted in the fourth quarter of 2017, amortization of stock-based awards, and all unallocated overhead cost associated with the execution of orders; processing of securities transactions; custody of client securities; receipt, identification, and delivery of funds and securities; compliance with regulatory and legal requirements; internal financial accounting and controls; and general administration and acquisition charges.

Earnings Per Share ("EPS")

Earnings Per Share [Abstract]

Earnings Per Share

NOTE 26 – Earnings Per Share (“EPS”)

Basic EPS is computed by dividing earnings available to common shareholders by the weighted-average number of common shares outstanding. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. Diluted earnings per share include dilutive stock options and stock units under the treasury stock method.

The following table sets forth the computation of basic and diluted earnings per share for the years ended December 31, 2018, 2017, and 2016 (in thousands, except per share data): 

	Year Ended December 31,
	2018		2017		2016
Net income	$	393,968	$	182,871	$	81,520
Preferred dividends		9,375		9,375		3,906
Net income available to common shareholders	$	384,593	$	173,496	$	77,614
Shares for basic and diluted calculation:
Average shares used in basic computation		71,786		68,562		66,871
Dilutive effect of stock options and units (1)		9,535		12,473		10,692
Average shares used in diluted computation		81,321		81,035		77,563
Earnings per common share:
Basic	$	5.36	$	2.53	$	1.16
Diluted	$	4.73	$	2.14	$	1.00

⁽¹⁾ Diluted earnings per share is computed on the basis of the weighted-average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Diluted earnings per share include stock options and units.

For the years ended December 31, 2018, 2017, and 2016, the anti-dilutive effect from restricted stock units was immaterial.

Cash Dividends

During the year ended December 31, 2018, we declared and paid cash dividends of $0.48 per common share. During the year ended December 31, 2017, we declared and paid cash dividends of $0.20 per common share. We did not declare or pay any dividends on our common stock during 2016.

Equity [Abstract]

Shareholders' Equity

NOTE 27 – Shareholders’ Equity

Share Repurchase Program

We have an ongoing authorization from the Board of Directors to repurchase our common stock in the open market or in negotiated transactions. In November 2018, the Board of Directors authorized the repurchase of an additional 5.3 million shares bringing the authorized share repurchase amount to 10.0 million shares. At December 31, 2018, the maximum number of shares that may yet be purchased under this plan was 9.0 million. The repurchase program has no expiration date. These purchases may be made on the open market or in privately negotiated transactions, depending upon market conditions and other factors. Repurchased shares may be used to meet obligations under our employee benefit plans and for general corporate purposes. During the year ended December 31, 2018, we repurchased $170.2 million or 3.4 million shares using existing Board authorization at an average price of $49.59 per share to meet obligations under our company’s employee benefit plans and for general corporate purposes. During the year ended December 31, 2017, we repurchased $13.0 million or 0.3 million shares using existing Board authorization at an average price of $43.83 per share to meet obligations under our company’s employee benefit plans and for general corporate purposes.

Issuance of Common Stock from Treasury

During the year ended December 31, 2018, we issued 0.5 million shares of common stock from treasury.

Share issuances out of treasury during the year ended December 31, 2018, were primarily a result of the vesting and exercise transactions under our incentive stock award plans.

During the year ended December 31, 2017, we issued 2.4 million shares of common stock from treasury.

Share issuances out of treasury during the year ended December 31, 2017, were primarily a result of the vesting and exercise transactions under our incentive stock award plans.

Issuance of Common Stock

On August 31, 2018, we issued approximately 2.0 million shares for acquisition of Business Bancshares, Inc. See Note 3 in the notes to consolidated financial statements for additional information regarding the acquisition.

On January 3, 2017, we issued 0.2 million shares related to the purchase of City Securities, Inc. See Note 3 in the notes to consolidated financial statements for additional information regarding the acquisition.

Issuance of Preferred Stock

On July 11, 2016, our company issued $150.0 million of perpetual 6.25% Non-Cumulative Perpetual Preferred Stock, Series A, $1.00 par value, with a liquidation preference of $25,000 per share (equivalent to $25 liquidation preference per depositary share).

When, as, and if declared by the board of directors of the company, dividends will be payable at an annual rate of 6.25%, payable quarterly, in arrears. We may redeem the Series A preferred stock at our option, subject to regulatory approval, on or after July 15, 2021, or following a regulatory capital treatment event, as defined.

Variable Interest Entities

Variable Interest Entity Not Primary Beneficiary Disclosures [Abstract]

Variable Interest Entities

NOTE 28 – Variable Interest Entities

Our company’s involvement with VIEs is limited to entities used as investment vehicles and private equity funds, the establishment of Stifel Financial Capital Trusts, and the ownership of a securitization that purchases, leases, and disposes of aircraft engines.

We have formed several non-consolidated investment funds with third-party investors that are typically organized as limited liability companies (“LLCs”) or limited partnerships. These partnerships and LLCs have assets of $231.8 million at December 31, 2018. For those funds where we act as the general partner, our company’s economic interest is generally limited to management fee arrangements as stipulated by the fund operating agreements. We have generally provided the third-party investors with rights to terminate the funds or to remove us as the general partner. Management fee revenue earned by our company was insignificant during the years ended December 31, 2018, 2017, and 2016. In addition, our direct investment interest in these entities is insignificant at December 31, 2018 and 2017.

Thomas Weisel Capital Management LLC, a subsidiary of our company, acts as the general partner of a series of investment funds in venture capital and fund of funds and manages investment funds that are active buyers of secondary interests in private equity funds, as well as portfolios of direct interests in venture-backed companies. These partnerships have combined assets of $227.0 million at December 31, 2018. We hold variable interests in these funds as a result of our company’s rights to receive management fees. Our company’s investment in and additional capital commitments to the private equity funds are also considered variable interests. The additional capital commitments are subject to call at a later date and are limited in amount. Our exposure to loss is limited to our investments in, advances and commitments to, and receivables due from these funds, and that exposure is insignificant at December 31, 2018. Management fee revenue earned by our company was insignificant during the years ended December 31, 2018, 2017, and 2016.

For the entities noted above that were determined to be VIEs, we have concluded that we are not the primary beneficiary, and therefore, we are not required to consolidate these entities. Additionally, for certain other entities, we reviewed other relevant accounting guidance, which states the general partner in a limited partnership is presumed to control that limited partnership. The presumption may be overcome if the limited partners have either: (1) the substantive ability to dissolve the limited partnership or otherwise remove the general partner without cause, or (2) substantive participating rights, which provide the limited partners with the ability to effectively participate in significant decisions that would be expected to be made in the ordinary course of the limited partnership’s business and thereby preclude the general partner from exercising unilateral control over the partnership. If the criteria are not met, the consolidation of the partnership or limited liability company is required. Based on our evaluation of these entities, we determined that these entities do not require consolidation.

Debenture to Stifel Financial Capital Trusts

We have completed private placements of cumulative trust preferred securities through Stifel Financial Capital Trust II, Stifel Financial Capital Trust III, and Stifel Financial Capital Trust IV (collectively, the “Trusts”). The Trusts are non-consolidated wholly owned business trust subsidiaries of our company and were established for the limited purpose of issuing trust securities to third parties and lending the proceeds to our company.

The trust preferred securities represent an indirect interest in junior subordinated debentures purchased from our company by the Trusts, and we effectively provide for the full and unconditional guarantee of the securities issued by the Trusts. We make timely payments of interest to the Trusts as required by contractual obligations, which are sufficient to cover payments due on the securities issued by the Trusts, and believe that it is unlikely that any circumstances would occur that would make it necessary for our company to make payments related to these Trusts other than those required under the terms of the debenture agreements and the trust preferred securities agreements. The Trusts were determined to be VIEs because the holders of the equity investment at risk do not have adequate decision-making ability over the Trust’s activities. Our investment in the Trusts is not a variable interest, because equity interests are variable interests only to the extent that the investment is considered to be at risk. Because our investment was funded by the Trusts, it is not considered to be at risk.

Securitization Interests

On July 31, 2018, the Company purchased 100% of the share capital of Jet Holding S.a.r.l. (“Jet Holdings”), which is the owner of 100% of the outstanding E-Certificates in FAN Engine Securitization Ltd. (“FAN”). FAN is a securitization which purchases, leases, and disposes of commercial aircraft engines. As of the acquisition date, FAN owned 24 leased aircraft engines through common law trusts and FAN Leasing Dublin Limited, all of which are wholly owned subsidiaries of FAN.

As the holder of the E-Certificate, our obligation to absorb losses is limited to the equity at risk (in this instance the consideration paid to acquire the E-Certificate). The residual returns that could be potentially generated by the activities of FAN are not pro rata with our ownership interests in the securitization.  In addition, we have the power to direct the activities of FAN. As such, we have determined that FAN is a variable interest entity with Jet Holdings the primary beneficiary; therefore, FAN has been consolidated at December 31, 2018.  Upon consolidation of FAN at fair value, which we determined was not a business, we recognized a gain of $15.3 million, which is included in other income in the consolidated statements of operations.

At December 31, 2018, the assets of FAN, which primarily consisted of operating leases, and liabilities, which primarily consisted of debt, were immaterial to our consolidated statements of financial condition.

NOTE 29 – Subsequent Events

We evaluate subsequent events that have occurred after the balance sheet date but before the financial statements are issued. There are two types of subsequent events: (1) recognized, or those that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements, and (2) non-recognized, or those that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Nature Of Operations

Nature of Operations

Stifel Financial Corp. (the “Company”), through its wholly owned subsidiaries, is principally engaged in retail brokerage; securities trading; investment banking; investment advisory; retail, consumer, and commercial banking; and related financial services. Our major geographic area of concentration is throughout the United States, with a growing presence in the United Kingdom and Europe. Our company’s principal customers are individual investors, corporations, municipalities, and institutions.

Basis Of Presentation

Basis of Presentation

The consolidated financial statements include Stifel Financial Corp. and its wholly owned subsidiaries, principally Stifel, Nicolaus & Company, Incorporated (“Stifel”), Keefe Bruyette & Woods (“KBW”), and Stifel Bancorp, Inc. (“Stifel Bancorp”). Unless otherwise indicated, the terms “we,” “us,” “our,” or “our company” in this report refer to Stifel Financial Corp. and its wholly owned subsidiaries.

The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles, which require management to make certain estimates and assumptions that affect the reported amounts. We consider significant estimates, which are most susceptible to change and impacted significantly by judgments, assumptions, and estimates, to be: valuation of financial instruments and investments in partnerships, accrual for contingencies, allowance for loan losses, derivative instruments and hedging activities, fair value of goodwill and intangible assets, provision for income taxes and related tax reserves, and forfeitures associated with stock-based compensation. Actual results could differ from those estimates.

Certain amounts from prior periods have been reclassified to conform to the current period’s presentation. The effect of these reclassifications on our company’s previously reported consolidated financial statements was not material.

Consolidation Policies

Consolidation Policies

The consolidated financial statements include the accounts of Stifel Financial Corp. and its subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. For consolidated subsidiaries that are less than wholly owned, the third-party holdings of equity interests are referred to as non-controlling interests. The portion of shareholders’ equity that is attributable to non-controlling interests for such subsidiaries is presented as non-controlling interests, a component of total equity, in the consolidated statements of financial condition.

Our non-controlling interest represents a 27.5% third-party ownership of North Shore Aviation Holdings LLC (“North Shore”), a wholly owned subsidiary of the Company, that through its subsidiary owns 5 airplane engines. See Note 9 for additional information on operating leases.

We also have investments or interests in other entities for which we must evaluate whether to consolidate by determining whether we have a controlling financial interest or are considered to be the primary beneficiary. In determining whether to consolidate these entities, we evaluate whether the entity is a voting interest entity or a variable interest entity (“VIE”). When we do not have a controlling interest in an entity, but we exert significant influence over the entity, we apply the equity method of accounting.

Voting Interest Entity

Voting Interest Entity – Voting interest entities are entities that have (i) total equity investment at risk sufficient to fund expected future operations independently, and (ii) equity holders who have the obligation to absorb losses or receive residual returns and the right to make decisions about the entity’s activities. We consolidate voting interest entities when we determine that there is a controlling financial interest, usually ownership of all, or a majority of, the voting interest.

Variable Interest Entity

Variable Interest Entity – VIEs are entities that lack one or more of the characteristics of a voting interest entity. We are required to consolidate certain VIEs in which we have the power to direct the activities of the entity and the obligation to absorb significant losses or receive significant benefits. In other cases, we consolidate VIEs when we are deemed to be the primary beneficiary. The primary beneficiary is defined as the entity that has a variable interest, or a combination of variable interests, that maintains control and receives benefits or will absorb losses that are not pro rata with its ownership interests.

The determination as to whether an entity is a VIE is based on the structure and nature of the entity. We also consider other characteristics, such as the ability to influence the decision-making relative to the entity’s activities and how the entity is financed. With the exception of entities eligible for the deferral codified in Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2010-10, “Consolidation: Amendments for Certain Investment Funds” (“ASU 2010-10”) (generally asset managers and investment companies), ASC 810 states that a controlling financial interest in an entity is present when an enterprise has a variable interest, or combination of variable interests, that have both the power to direct the activities of the entity that most significantly impact the entity’s economic performance and the obligation to absorb losses of the entity or the rights to receive benefits from the entity that could potentially be significant to the entity.

Entities meeting the deferral provision defined by ASU 2010-10 are evaluated under the historical VIE guidance. Under the historical guidance, a controlling financial interest in an entity is present when an enterprise has a variable interest, or combination of variable interests, that will absorb a majority of the entity’s expected losses, receive a majority of the entity’s expected residual returns, or both. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE.

We determine whether we are the primary beneficiary of a VIE by first performing a qualitative analysis of the VIE’s control structure, expected benefits and losses, and expected residual returns. This analysis includes a review of, among other factors, the VIE’s capital structure, contractual terms, which interests create or absorb benefits or losses, variability, related party relationships, and the design of the VIE. Where a qualitative analysis is not conclusive, we perform a quantitative analysis. We reassess our initial evaluation of an entity as a VIE and our initial determination of whether we are the primary beneficiary of a VIE upon the occurrence of certain reconsideration events. See Note 28 for additional information on VIEs.

Summary Of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2018

Accounting Policies [Abstract]

Cash and Cash Equivalents

Cash and Cash Equivalents

We consider money market mutual funds and highly liquid investments with original maturities of three months or less that are not restricted or segregated to be cash equivalents. Cash and cash equivalents include deposits with banks, federal funds sold, money market mutual funds, and certificates of deposit. Cash and cash equivalents also include balances that our bank subsidiaries maintain at the Federal Reserve Bank.

Cash Segregated For Regulatory Purposes

Cash Segregated for Regulatory Purposes

Our broker-dealer subsidiaries are subject to Rule 15c3-3 under the Securities Exchange Act of 1934, which requires our company to maintain cash or qualified securities in a segregated reserve account for the exclusive benefit of its clients. In accordance with Rule 15c3-3, our company has portions of its cash segregated for the exclusive benefit of clients at December 31, 2018.

Brokerage Client Receivables, Net

Brokerage Client Receivables, Net

Brokerage client receivables include receivables of our company’s broker-dealer subsidiaries, which represent amounts due on cash and margin transactions and are generally collateralized by securities owned by clients. Brokerage client receivables, primarily consisting of floating-rate loans collateralized by customer-owned securities, are charged interest at rates similar to other such loans made throughout the industry. The receivables are reported at their outstanding principal balance net of allowance for doubtful accounts. When a brokerage client receivable is considered to be impaired, the amount of the impairment is generally measured based on the fair value of the securities acting as collateral, which is measured based on current prices from independent sources, such as listed market prices or broker-dealer price quotations. Securities owned by customers, including those that collateralize margin or other similar transactions, are not reflected in the consolidated statements of financial condition.

Securities Borrowed and Securities Loaned

Securities Borrowed and Securities Loaned

Securities borrowed require our company to deliver cash to the lender in exchange for securities and are included in receivables from brokers, dealers, and clearing organizations in the consolidated statements of financial condition. For securities loaned, we generally receive collateral in the form of cash in an amount in excess of the market value of securities loaned. Securities loaned are included in payables to brokers, dealers, and clearing organizations in the consolidated statements of financial condition. We monitor the market value of securities borrowed and loaned on a daily basis, with additional collateral obtained or refunded as necessary. Fees received or paid are recorded in interest revenue or interest expense in the consolidated statements of operations.

Substantially all of these transactions are executed under master netting agreements, which gives us right of offset in the event of counterparty default; however, such receivables and payables with the same counterparty are not set off in the consolidated statements of financial condition.

Securities Purchased Under Agreements to Resell and Repurchase Agreements

Securities Purchased Under Agreements to Resell and Repurchase Agreements

Securities purchased under agreements to resell (“resale agreements”) are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. We obtain control of collateral with a market value equal to or in excess of the principal amount loaned and accrued interest under resale agreements. These agreements are short-term in nature and are generally collateralized by U.S. government securities, U.S. government agency securities, and corporate bonds. We value collateral on a daily basis, with additional collateral obtained when necessary to minimize the risk associated with this activity.

Securities sold under agreements to repurchase (“repurchase agreements”) are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. We make delivery of securities sold under agreements to repurchase and monitor the value of collateral on a daily basis. When necessary, we will deliver additional collateral.

Financial Instruments

Financial Instruments

We measure certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents, financial instruments owned, available-for-sale securities, investments, financial instruments sold, but not yet purchased, and derivatives. Other than those separately discussed in the notes to the consolidated financial statements, the remaining financial instruments are generally short-term in nature, and their carrying values approximate fair value.

The fair value of a financial instrument is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., “the exit price”) in an orderly transaction between market participants at the measurement date. We have categorized our financial instruments measured at fair value into a three-level classification in accordance with Topic 820, “Fair Value Measurement,” which established a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed 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. The hierarchy is broken down into three levels based on the transparency of inputs as follows:

Level 1 – Quoted prices (unadjusted) are available in active markets for identical assets or liabilities as of the measurement date. A quoted price for an identical asset or liability in an active market provides the most reliable fair value measurement, because it is directly observable to the market.

Level 2 – Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the measurement date. The nature of these financial instruments includes instruments for which quoted prices are available but traded less frequently, derivative instruments whose fair value have been derived using a model where inputs to the model 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 measurement date. These financial instruments do not have two-way markets and 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.

Valuation of Financial Instruments

When available, we use observable market prices, observable market parameters, or broker or dealer prices (bid and ask prices) to derive the fair value of financial instruments. In the case of financial instruments transacted on recognized exchanges, the observable market prices represent quotations for completed transactions from the exchange on which the financial instrument is principally traded.

A substantial percentage of the fair value of our financial instruments owned, available-for-sale securities, investments, and financial instruments sold, but not yet purchased, are based on observable market prices, observable market parameters, or derived from broker or dealer prices. The availability of observable market prices and pricing parameters can vary from product to product. Where available, observable market prices and pricing or market parameters in a product may be used to derive a price without requiring significant judgment. In certain markets, observable market prices or market parameters are not available for all products, and fair value is determined using techniques appropriate for each particular product. These techniques involve some degree of judgment.

For investments in illiquid or privately held securities that do not have readily determinable fair values, the determination of fair value requires us to estimate the value of the securities using the best information available. Among the factors we consider in determining the fair value of investments are the cost of the investment, terms and liquidity, developments since the acquisition of the investment, the sales price of recently issued securities, the financial condition and operating results of the issuer, earnings trends and consistency of operating cash flows, the long-term business potential of the issuer, the quoted market price of securities with similar quality and yield that are publicly traded, and other factors generally pertinent to the valuation of investments. In instances where a security is subject to transfer restrictions, the value of the security is based primarily on the quoted price of a similar security without restriction but may be reduced by an amount estimated to reflect such restrictions. The fair value of these investments is subject to a high degree of volatility and may be susceptible to significant fluctuation in the near term, and the differences could be material.

The degree of judgment used in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Pricing observability is impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, and the characteristics specific to the transaction. Financial instruments with readily available active quoted prices for which fair value can be measured from actively quoted prices generally will have a higher degree of pricing observability and a lesser degree of judgment used in measuring fair value. Conversely, financial instruments rarely traded or not quoted will generally have less, or no, pricing observability and a higher degree of judgment used in measuring fair value. See Note 5 for additional information on how we value our financial instruments.

Available-for-Sale and Held-to-Maturity Securities

Available-for-Sale and Held-to-Maturity Securities

Securities available for sale, which are carried at fair value, include U.S. government agency securities; state and municipal securities; agency, non-agency, and commercial mortgage-backed securities; corporate fixed income securities; and asset-backed securities, which primarily includes collateralized loan obligations.

Securities held to maturity are recorded at amortized cost based on our company’s positive intent and ability to hold these securities to maturity. Securities held to maturity include agency, commercial, and non-agency mortgage-backed securities, asset-backed securities, consisting of collateralized loan obligation securities and ARS, and corporate fixed income securities.

We evaluate all securities in an unrealized loss position quarterly to assess whether the impairment is other-than-temporary. Our other-than-temporary impairment (“OTTI”) assessment is a subjective process requiring the use of judgments and assumptions. Accordingly, we consider a number of qualitative and quantitative criteria in our assessment, including the extent and duration of the impairment, recent events specific to the issuer and/or industry to which the issuer belongs, the payment structure of the security, external credit ratings and the failure of the issuer to make scheduled interest or principal payments, the value of underlying collateral, current market conditions, and our company’s ability and intent to hold the investment until its value recovers or the securities mature. We may determine that the decline in fair value of an investment is other-than-temporary if our analysis of these factors indicates that we will not recover our investment in the securities.

If we determine that impairment on our debt securities is other-than-temporary and we have made the decision to sell the security or it is more likely than not that we will be required to sell the security prior to recovery of its amortized cost basis, we recognize the entire portion of the impairment in earnings. If we have not made a decision to sell the security and we do not expect that we will be required to sell the security prior to recovery of the amortized cost basis, we recognize only the credit component of OTTI in other operating expenses in the consolidated statements of operations. The remaining unrealized loss due to factors other than credit, or the non-credit component, is recorded in accumulated other comprehensive loss. We determine the credit component based on the difference between the security’s amortized cost basis and the present value of its expected future cash flows, discounted based on the purchase yield. The non-credit component represents the difference between the security’s fair value and the present value of expected future cash flows.

We estimate the portion of loss attributable to credit using a discounted cash flow model. Key assumptions used in estimating the expected cash flows include default rates, loss severity, and prepayment rates. Assumptions used can vary widely based on the collateral underlying the securities and are influenced by factors such as collateral type, loan interest rate, geographical location of the borrower, and borrower characteristics.

Unrealized gains and losses on our available-for-sale securities are reported, net of taxes, in accumulated other comprehensive loss included in shareholders’ equity. Amortization of premiums and accretion of discounts are recorded as interest income in the consolidated statements of operations using the interest method. Realized gains and losses from sales of securities available for sale are determined on a specific identification basis and are included in other income in the consolidated statements of operations in the period they are sold. For securities transferred from available-for-sale to held-to-maturity, carrying value also includes unrealized gains and losses recognized in accumulated other comprehensive loss at the date of transfer. Such unrealized gains or losses are accreted over the remaining life of the security with no impact on future net income.

Loan Classification

Loan Classification

We classify loans based on our investment strategy and management’s assessment of our intent and ability to hold loans for the foreseeable future or until maturity. Management’s intent and ability with respect to certain loans may change from time to time depending on a number of factors, including economic, liquidity, and capital conditions. The accounting and measurement framework for loans differs depending on the loan classification. The classification criteria and accounting and measurement framework for bank loans and loans held for sale are described below.

Bank Loans and Allowance for Loan Losses

Bank loans consist of commercial and residential mortgage loans, commercial and industrial loans, stock-secured loans, home equity loans, construction loans, and consumer loans originated or acquired by Stifel Bancorp. Bank loans include those loans that management has the intent and ability to hold and are recorded at outstanding principal adjusted for any charge-offs, allowance for loan losses, deferred origination fees and costs, and purchased discounts. Loan origination costs, net of fees, and premiums and discounts on purchased loans are deferred and recognized over the contractual life of the loan as an adjustment of yield using the interest method. Bank loans are generally collateralized by real estate, real property, marketable securities, or other assets of the borrower. Interest income is recognized using the effective interest rate method, which is based upon the respective interest rates and the average daily asset balance. Discount accretion/premium amortization is recognized using the effective interest rate method, which is based upon the respective interest rate and expected lives of loans.

We regularly review the loan portfolio and have established an allowance for loan losses for inherent losses estimated to have occurred in the loan portfolio through a provision for loan losses charged to other operating expenses in the consolidated statements of operations. In providing for the allowance for loan losses, we consider historical loss experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available.

Loans Held for Sale

Loans that we intend to sell or for which we do not have the ability and intent to hold for the foreseeable future are classified as held for sale. Loans held for sale consist of fixed-rate and adjustable-rate residential and multi-family real estate mortgage loans intended for sale. Loans held for sale are stated at lower of cost or market value on an individual loan basis. Declines in market value below cost and any gains or losses on the sale of these assets are recognized in other income in the consolidated statements of operations. Market value is determined based on prevailing market prices for loans with similar characteristics or on sale contract prices. Deferred fees and costs related to these loans are not amortized but are recognized as part of the cost basis of the loan at the time it is sold. Because loans held for sale are reported at lower of cost or market value, an allowance for loan losses is not established for loans held for sale.

Impaired Loans

Impaired Loans

A loan is considered impaired when, based on current information and events, it is probable that the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement will not be collectible. Factors considered in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. We determine the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed.

We consider a loan a trouble debt restructuring when an existing borrower is granted concessionary rates or terms, which would not otherwise be offered. The concessions granted do not reflect current market conditions for a new loan of similar risk to another borrower in similar financial circumstances.

Once a loan is determined to be impaired, when principal or interest becomes 90 days past due or when collection becomes uncertain, the accrual of interest and amortization of deferred loan origination fees is discontinued (“non-accrual status”) and any accrued and unpaid interest income is reversed. Loans placed on non-accrual status are returned to accrual status when all delinquent principal and interest payments are collected and the collectibility of future principal and interest payments is reasonably assured. Loan losses are charged against the allowance for loan losses when we believe the uncollectibility of a loan balance is certain. Subsequent recoveries, if any, are credited to the allowance for loan losses.

Large groups of smaller balance homogenous loans are collectively evaluated for impairment. Accordingly, we do not separately identify individual consumer and residential loans for impairment measurements. Impairment is measured on a loan-by-loan basis for non-homogeneous loans, and a specific allowance is established for individual loans determined to be impaired. Impairment is measured by comparing the carrying value of the impaired loan to the present value of its expected cash flow discounted at the loan’s effective interest rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent.

Investments

Investments

Our broker-dealer subsidiaries report changes in fair value of marketable and non-marketable securities in other income in the consolidated statements of operations. The fair value of marketable investments is generally based on either quoted market or dealer prices. The fair value of non-marketable securities is based on management’s estimate using the best information available, which generally consists of quoted market prices for similar securities and internally developed discounted cash flow models.

Investments in the consolidated statements of financial condition contain investments in securities that are marketable and securities that are not readily marketable. These investments are not included in our broker-dealer trading inventory or available-for-sale or held-to-maturity portfolios and represent the acquiring and disposing of debt or equity instruments for our benefit.

Fixed Assets, Net

Fixed Assets, Net

Office equipment is depreciated on a straight-line basis over the estimated useful life of the asset of two to seven years. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or the term of the lease. Buildings and building improvements are amortized on a straight-line basis over the estimated useful life of the asset of three to thirty-nine years. Depreciation expense is recorded in occupancy and equipment rental in the consolidated statements of operations. Office equipment, leasehold improvements, and property are stated at cost net of accumulated depreciation and amortization in the consolidated statements of financial condition. Fixed assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable.

Goodwill and Intangible Assets

Goodwill and Intangible Assets

Goodwill represents the cost of acquired businesses in excess of the fair value of the related net assets acquired. We test goodwill for impairment on an annual basis and on an interim basis when certain events or circumstances exist. We test for impairment at the reporting unit level, which is generally at the level of or one level below our company’s business segments. For both the annual and interim tests, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads 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 or circumstances, we determine it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then performing the two-step impairment test is not required. However, if we conclude otherwise, we are then required to perform the first step of the two-step impairment test. Goodwill impairment is determined by comparing the estimated fair value of a reporting unit with its respective carrying value. If the estimated fair value exceeds the carrying value, goodwill at the reporting unit level is not deemed to be impaired. If the estimated fair value is below carrying value, however, further analysis is required to determine the amount of the impairment. Additionally, if the carrying value of a reporting unit is zero or a negative value and it is determined that it is more likely than not the goodwill is impaired, further analysis is required. The estimated fair values of the reporting units are derived based on valuation techniques we believe market participants would use for each of the reporting units. The Company performed impairment testing on October 1, 2018 with no impairment charges resulting from the annual impairment tests.

Identifiable intangible assets, which are amortized over their estimated useful lives, are tested for potential impairment whenever events or changes in circumstances suggest that the carrying value of an asset or asset group may not be fully recoverable.

Loan and Advances to Financial Advisors and Other Employees, Net

Loans and Advances to Financial Advisors and Other Employees, Net

We offer transition pay, principally in the form of upfront loans, to financial advisors and certain key revenue producers as part of our company’s overall growth strategy. These loans are generally forgiven by a charge to compensation and benefits over a five- to ten-year period if the individual satisfies certain conditions, usually based on continued employment and certain performance standards. We monitor and compare individual financial advisor production to each loan issued to ensure future recoverability. If the individual leaves before the term of the loan expires or fails to meet certain performance standards, the individual is required to repay the balance. In determining the allowance for doubtful receivables from former employees, management considers the facts and circumstances surrounding each receivable, including the amount of the unforgiven balance, the reasons for the terminated employment relationship, and the former employees’ overall financial situation.

Derivative Instruments And Hedging Activities

Derivative Instruments and Hedging Activities

We recognize all of our derivative instruments at fair value as either assets or liabilities in the consolidated statements of financial condition. These instruments are recorded in other assets or accounts payable and accrued expenses in the consolidated statements of financial condition and in the operating section of the consolidated statements of cash flows as increases or decreases of other assets and accounts payable and accrued expenses. Our company’s policy is not to offset fair value amounts recognized for derivative instruments and fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral arising from derivative instruments recognized at fair value executed with the same counterparty under master netting arrangements. The accounting for changes in the fair value (i.e., gains and losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, we must also designate the hedging instrument or transaction, based upon the exposure being hedged.

For derivative instruments that are designated and qualify as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive loss, net of tax, and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item, if any, is recognized in current earnings during the period of change. We do not use derivatives for trading or speculative purposes and, at December 31, 2018, all of our derivatives are designated as cash flow hedges. See Note 14 for additional details.

Revenue Recognition

Revenue Recognition

Customer securities transactions are recorded on a settlement date basis, with related commission revenues and expenses recorded on a trade date basis. Commission revenues are recorded as the amount charged to the customer, which, in certain cases, may include varying discounts. Principal securities transactions are recorded on a trade date basis. We typically distribute our proprietary equity research products to our client base of institutional investors at no charge. These proprietary equity research products are accounted for as a cost of doing business.

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.

Advisory expenses had historically been deferred until reimbursed by the client, the related fee revenue was recognized or the engagement was 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 has been recognized. All other investment banking advisory related expenses, including expenses incurred related to restructuring assignments, are expensed as incurred.

Underwriting expenses had historically been recorded net of client reimbursements and/or netted against revenues. Under the new revenue standard, all investment banking expenses are recognized as non-interest expense in other operating expenses in the consolidated statements of operations and any expense reimbursements are recognized as investment banking revenues (i.e., expenses are no longer recorded net of client reimbursements and are not netted against revenues).

Asset management and service fees. We earn management and performance fees in connection with investment advisory services provided to institutional and individual clients. Investment advisory fees are charged based on the value of assets in fee-based accounts and are affected by changes in the balances of client assets due to market fluctuations and levels of net new client assets. Fees are charged either in advance based on fixed rates applied to the value of the customers’ account at the beginning of the period or periodically based on contracted rates and account performance. Contracts can be terminated at any time with no incremental payments due to our company upon termination. If the contract is terminated by the customer fees are prorated for the period and fees charged for the post termination period are refundable to the customer.

We earn fees from the investment partnerships that we manage or of which we are a general partner. Such management fees are generally based on the net assets or committed capital of the underlying partnerships. We have agreed, in certain cases, to waive management fees, in lieu of making a cash contribution, in satisfaction of our general partner investment commitments to the investment partnerships. In these cases, we generally recognize our management fee revenues at the time when we are allocated a special profit interest in realized gains from these partnerships.

Direct Financing And Operating Leases

Direct Financing andOperating Leases

The net investment in direct financing leases is included in other assets in the consolidated balance sheets and consists of the present values of the sum of the future minimum lease payments and estimated residual value of the leased assets. Revenue consists of interest earned on the net investment and is recognized over the lease term as a constant percentage return thereon. The net investment in property on operating leases is included in fixed assets, net in the consolidated balance sheets. Depreciation is recognized, on the straight-line basis, over the lease term to the estimated residual value. Operating lease revenue is recorded on a straight-line basis and is recognized over the lease term in other income. Estimated residual values are established at lease inception utilizing contract terms, past customer experience, and general market data and are reviewed and adjusted, if necessary, on an annual basis. See Note 3 – Acquisitions for further details.

We lease office space and equipment under operating leases. We recognize rent expense related to these operating leases on a straight-line basis over the lease term. The lease term commences on the earlier of the date when we become legally obligated for the rent payments or the date on which we take possession of the property. For tenant improvement allowances and rent holidays, we record a deferred rent liability in accounts payable and accrued expenses in the consolidated statements of financial condition and amortize the deferred rent over the lease term as a reduction to occupancy and equipment rental in the consolidated statements of operations.

Income Taxes

Income Taxes

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“Tax Legislation”) was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017.

We compute income taxes using the asset and liability method, under which deferred income taxes are provided for the temporary differences between the financial statement carrying amounts and the tax basis of our company’s assets and liabilities. We establish a valuation allowance for deferred tax assets if it is more likely than not that these items will either expire before we are able to realize their benefits, or that future deductibility is uncertain.

We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. We recognize interest and penalties related to uncertain tax positions in provision for income taxes in the consolidated statements of operations. See Note 24 for further information regarding income taxes.

Foreign Currency Translation

Foreign Currency Translation

We consolidate our foreign subsidiaries, which have designated their local currency as their functional currency. Assets and liabilities of these foreign subsidiaries are translated at year-end rates of exchange. Revenues and expenses are translated at an average rate for the period. Gains or losses resulting from translating foreign currency financial statements are reflected in accumulated other comprehensive loss, a separate component of Stifel Financial Corp. shareholders’ equity. Gains or losses resulting from foreign currency transactions are included in other income in the consolidated statements of operations.

Recently Issued Accounting Guidance

Recently Issued Accounting Guidance

Fair Value Measurement

In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The objective of this guidance is to improve the effectiveness of disclosure requirements on fair value measurement by eliminating certain disclosure requirements for fair value measurements for all entities, requiring public entities to disclose certain new information and modifying some disclosure requirements. The accounting update is effective for the fiscal year beginning after December 15, 2019 (January 1, 2020 for our company) and early adoption is permitted. The adoption is not expected to have a material impact on our consolidated financial statements.

Derivatives and Hedging

In August 2017, the FASB issued ASU 2017-12, “Targeted Improvements to Accounting for Hedging Activities,” which amends the hedge accounting recognition and presentation requirements. The accounting update improves the transparency and understandability of information conveyed to financial statement users by better aligning companies’ hedging relationship to their existing risk management strategies, simplifies the application of hedge accounting and increases transparency regarding the scope and results of hedging program. The accounting update is effective for the fiscal year beginning after December 15, 2018 (January 1, 2019 for our company) and early adoption is permitted. The Company will not early adopt this accounting update. We are currently evaluating the impact of the accounting update, but the adoption is not expected to have a material impact on our consolidated financial statements.

Callable debt securities

In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities,” which shortens the amortization period for the premium on certain callable debt securities to the earliest call date. The amendments are applicable to any purchased individual debt security with an explicit and non-contingent call feature that is callable at a fixed price on a preset date. The accounting update is effective for fiscal years beginning after December 15, 2018 (January 1, 2019 for our company) under a modified retrospective approach and early adoption is permitted. We are evaluating the impact the adoption of this new guidance will have on our consolidated financial statements.

Goodwill Impairment Testing

In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. Under the accounting update, the annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, and an impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The accounting update is effective for annual or any interim impairment tests in fiscal years beginning after December 15, 2019 (January 1, 2020 for our company) and early adoption is permitted. We are currently evaluating the impact of the accounting update, but the adoption is not expected to have a material impact on our consolidated financial statements.

Financial Instruments – Credit Losses

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments − Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.”  This accounting update impacts the impairment model for certain financial assets measured at amortized cost by requiring a current expected credit loss (“CECL”) methodology to estimate expected credit losses over the entire life of the financial asset, recorded at inception or purchase. CECL will replace the loss model currently applicable to bank loans, held-to-maturity securities, and other receivables carried at amortized cost.

The accounting update also eliminates the concept of other-than-temporary impairment for available-for-sale securities. Impairments on available-for-sale securities will be required to be recognized in earnings through an allowance, when the fair value is less than amortized cost and a credit loss exists or the securities are expected to be sold before recovery of amortized cost. Under the accounting update, there may be an ability to determine there are no expected credit losses in certain circumstances, e.g., based on collateral arrangements for lending and financing transactions or based on the credit quality of the borrower or issuer.

Overall, the amendments in this accounting update are expected to accelerate the recognition of credit losses for portfolios where CECL models will be applied. The accounting update is effective for fiscal years beginning after December 15, 2019 (January 1, 2020 for our company) with early adoption permitted as of January 1, 2019. We are in the process of developing credit models with the assistance of third-party vendors and assessing process changes that may be required for accounting, reporting and governance to comply with the new credit standard.  We are also currently evaluating the impact of the accounting update, but the adoption is not expected to have a material impact on our consolidated financial statements.

Leases

In February 2016, the FASB issued ASU 2016-02, “Leases,” (“ASU 2016-02”) that requires for leases longer than one year, a lessee recognize in the statements of financial condition a right-of-use asset, representing the right to use the underlying asset for the lease term, and a lease liability, representing the liability to make lease payments. The accounting update also requires that for finance leases, a lessee recognize interest expense on the lease liability, separately from the amortization of the right-of-use asset in the statements of earnings, while for operating leases, such amounts should be recognized as a combined expense. In addition, this accounting update requires expanded disclosures about the nature and terms of lease agreements.

We will adopt ASU 2016-02 utilizing the optional transition approach allowed under ASU 2018-11, “Leases (Topic 842): Targeted Improvements” and applying the package of practical expedients beginning January 1, 2019. This option allows entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. By applying ASU 2016-02 at the adoption date, as opposed to at the beginning of the earliest period presented, our reporting for periods prior to January 1, 2019 will continue to be reported in accordance with Leases (Topic 840).

The adoption of this guidance will result in the addition of right-of-use assets and corresponding lease obligations to the consolidated balance sheet and will not have a material impact on the Company’s results of operations or cash flows. Upon adoption, the Company expects to record operating lease right-of-use assets in the range of approximately $600 million to $700 million, representing the present value of future lease payments under operating leases with terms of greater than twelve months, with corresponding operating lease liabilities. These amounts are impacted by certain assumptions around lease renewals and the discount rate used to discount the future lease obligations. We do not believe the standard will materially affect our consolidated statements of income or consolidated statements of cash flows. The standard will have no impact on our debt covenant compliance under our current agreements.

Recently Adopted Accounting Guidance

Recently Adopted Accounting Guidance

Comprehensive Income

In February 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” that provides for the reclassification from accumulated other comprehensive income to retained earnings for stranded effects resulting from the Tax Cuts and Jobs Act of 2017. The accounting update is effective for the fiscal year beginning after December 15, 2018 (January 1, 2019 for our company) and early adoption is permitted. We early adopted the guidance in the update on January 1, 2018. The adoption of the accounting update resulted in a reclassification adjustment of $3.1 million related to cash flow hedges and investment portfolio credit risk in our consolidated financial statements.

Statement of Cash Flow

In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flow - Restricted Cash,” which adds or clarifies guidance on the classification and presentation of restricted cash in the statement of cash flows. The accounting update is effective for the fiscal year beginning after December 15, 2017. We adopted the guidance in the update on January 1, 2018. The adoption of the accounting update did not have a material impact on our consolidated statement of cash flows. Upon adoption of the accounting update, we recorded an increase of $17.6 million in net cash provided by operating activities and an increase of $153.8 million in net cash used in operating activities for the years ended December 31, 2017 and 2016, respectively, related to reclassifying the changes in our cash segregated for regulatory purposes and restricted cash balance from operating activities to the cash and cash equivalent balances within the consolidated statements of cash flows.

In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” which amends and clarifies the current guidance to reduce diversity in practice of the classification of certain cash receipts and payments in the consolidated statements of cash flows. The accounting update is effective for the fiscal year beginning after December 31, 2017. We adopted the guidance in the update on January 1, 2018. The adoption of the accounting update did not have a material impact on our consolidated statements of cash flows.

Financial Assets and Financial Liabilities

In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” that changes the income statement impact of equity investments held by an entity, and the recognition of changes in fair value of financial liabilities when the fair value option is elected. The accounting update also amends certain disclosure requirements associated with the fair value of financial instruments. The accounting update is effective for fiscal years beginning after December 15, 2017. We adopted the guidance in the update on January 1, 2018. The adoption of the accounting update did not have a material impact on our consolidated financial statements.

Revenue Recognition

In May 2014, the FASB issued ASU 2014-09, “Revenue From Contracts With Customers (Topic 606),” (“ASU 2014-09”) that supersedes current revenue recognition guidance, including most industry-specific guidance. ASU 2014-09, as amended, requires a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services. The guidance also requires additional disclosures regarding the nature, amount, timing, and uncertainty of revenue that is recognized.

Effective January 1, 2018, the Company adopted ASU 2014-09, which provides accounting guidance on the recognition of revenues from contracts and requires gross presentation of certain costs that were previously offset against revenue. This change was applied prospectively from January 1, 2018 and there is no impact on our previously presented results. The adoption of the new revenue standard resulted in a reduction of beginning retained earnings of $4.2 million after-tax as a cumulative effect of adoption of an accounting change.

The impact of adoption is primarily related to investment banking revenues that were previously recognized in prior periods, which are now being deferred under the new revenue standard.

With the adoption of the new revenue recognition standard on January 1, 2018, capital raising and advisory fee revenues are no longer presented net of the related reimbursable deal expenses. As a result, capital raising and advisory fee revenues and other operating expenses are higher in 2018 by an identical $33.8 million, with no impact to net income.

The scope of the accounting update does not apply to revenue associated with financial instruments, and as a result, does not have an impact on the elements of our consolidated statements of operations most closely associated with financial instruments, including principal transaction revenues, interest income, and interest expense.

Share-Based Payments

In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”) that requires an entity to record all excess tax benefits and tax deficiencies as an income tax benefit or expense in the income statement. ASU 2016-09 also requires an entity to elect an accounting policy to either estimate the number of forfeitures or account for forfeitures when they occur. The guidance is effective for fiscal years beginning after December 15, 2016 (January 1, 2017 for our company). We adopted the guidance in the update on January 1, 2017. Cash paid to a tax authority by a company when withholding shares from an employee’s award for tax-withholding purposes are now classified as a financing activity in the accompanying consolidated statement of cash flows (adopted retrospectively). We reclassified $61.6 million from operating activities to financing activities in the accompanying consolidated statement of cash flows for the year ended December 31, 2016 pertaining to shares withheld from employee awards for tax withholding purposes.
