SOTHEBY’S

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. Basis of Presentation

Accounting Principles—The unaudited Condensed Consolidated Financial Statements included herein have been prepared by the management of Sotheby’s (or the "Company") in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") and pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted from this report, as is permitted by such rules and regulations. In our opinion, the unaudited Condensed Consolidated Financial Statements reflect all adjustments of a normal recurring nature that are necessary for a fair presentation of the results for the interim periods presented. Interim results are not necessarily indicative of results for a full year (see Note 2). We urge you to read these Condensed Consolidated Financial Statements in conjunction with the information included in our 2016 Form 10-K filed with the SEC on February 27, 2017.

Principles of Consolidation—The unaudited Condensed Consolidated Financial Statements include the accounts of our wholly-owned subsidiaries and Sotheby's (Beijing) Auction Co., Ltd. ("Sotheby's Beijing"), a joint venture in which we have a controlling 80% ownership interest. The net income (loss) attributable to the minority owner of Sotheby's Beijing is reported as "Net Income (Loss) Attributable to Noncontrolling Interest" in our Condensed Consolidated Income Statements and the non-controlling 20% ownership interest is reported as "Noncontrolling Interest" within the Equity section of our Condensed Consolidated Balance Sheets. Intercompany transactions and balances among our subsidiaries are eliminated in consolidation.

Equity investments through which we exercise significant influence over the investee, but do not control, are accounted for using the equity method. Under the equity method, our share of investee earnings or losses is recorded within Equity in Earnings of Investees in our Condensed Consolidated Income Statements. Our interest in the net assets of these equity method investees is recorded within Other Long-Term Assets on our Condensed Consolidated Balance Sheets. Our equity method investees include: (i) Acquavella Modern Art ("AMA"), a partnership through which a collection of fine art is being sold, (ii) RM Sotheby's, an auction house for investment-quality automobiles, and (iii) a partnership formed in the second quarter of 2017 through which artworks are being purchased and sold (see Note 10).

Presentation of Salaries and Related Costs—We do not allocate salaries and related costs to our cost of revenue, marketing expense, and general and administrative expense line items, as many employees often perform duties that could be categorized across more than one of these line items.

Estimates and Assumptions—The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Adoption of Accounting Standards Update ("ASU") 2016-09—In March 2016, the Financial Accounting Standards Board (the "FASB") issued ASU 2016-09, Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies several aspects of the accounting and presentation of share-based payment transactions, including the accounting for the related income tax consequences and certain classifications within the statement of cash flows. We adopted ASU 2016-09 on its effective date of January 1, 2017.

ASU 2016-09 requires that all excess tax benefits and deficiencies resulting from the vesting of share-based payments be recorded in the statement of operations, whereas previous guidance generally permitted such items to be recorded in the equity section of the balance sheet provided that an adequate level of previously recorded excess tax benefits existed. We adopted this aspect of ASU 2016-09 on a prospective basis beginning on January 1, 2017. The adoption of ASU 2016-09 and the vesting of certain share-based payments in the first quarter of 2017 resulted in the recording of a discrete $2.6 million income tax benefit in our Condensed Consolidated Income Statements, which decreased our effective income tax rate for the six months ended June 30, 2017 by approximately 3%. Under previous guidance, this income tax benefit would have been recorded as an increase to Additional Paid-In Capital on our Condensed Consolidated Balance Sheets.

7

ASU 2016-09 also changed how excess tax benefits resulting from the vesting of share-based payments are presented in the statement of cash flows. ASU 2016-09 requires that such excess tax benefits be classified within Operating Activities along with other income tax cash flows. Under previous guidance, excess tax benefits resulting from the vesting of share-based payments were presented as a cash inflow within Financing Activities and a corresponding cash outflow within Operating Activities. The adoption of ASU 2016-09 in the first quarter of 2017 resulted in the classification of $2.6 million of excess tax benefits within Operating Activities in our Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2017. The retrospective adoption of ASU 2016-09 did not have an effect on our Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2016 because no excess tax benefits were recorded in that period.

The adoption of the other aspects of ASU 2016-09 did not have a material impact on our Condensed Consolidated Financial Statements as of and for the three and six months ended June 30, 2017 and 2016.

Adoption of Other Recently Issued Accounting Standards—In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging: Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships, which clarifies that a change in the counterparty to a derivative instrument that has been designated as a hedging instrument would not, in and of itself, be considered a termination of the derivative instrument, provided that all other hedge accounting criteria continue to be met. The adoption of ASU 2016-05 on its effective date of January 1, 2017 did not have a material effect on our Condensed Consolidated Financial Statements as of and for the three and six months ended June 30, 2017 and 2016.

In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging-Contingent Put and Call Options in Debt Instruments, which aims to reduce the diversity of practice in identifying embedded derivatives in debt instruments. ASU 2016-06 clarifies that the nature of an exercise contingency is not subject to the “clearly and closely” criteria for purposes of assessing whether the call or put option must be separated from the debt instrument and accounted for separately as a derivative. The adoption of ASU 2016-06 on its effective date of January 1, 2017 did not have a material effect on our Condensed Consolidated Financial Statements as of and for the three and six months ended June 30, 2017 and 2016.

2. Seasonality of Business

The global art auction market has two principal selling seasons, which generally occur in the second and fourth quarters of the year. In the aggregate, second and fourth quarter Net Auction Sales¹ represented 82% and 78% of our total annual Net Auction Sales for the years ended December 31, 2016 and 2015, respectively, with auction commission revenues comprising approximately 75%of our total revenues in each of those years. Accordingly, our financial results are seasonal, with peak revenues and operating income generally occurring in the second and fourth quarters. Consequently, first and third quarter results have historically reflected lower revenues when compared to the second and fourth quarters and, typically, a net loss due to the fixed nature of many of our operating expenses.

___________________________________________________________________

3. Segment Reporting

Sotheby's is a global art and luxury business, offering its clients opportunities to connect with and transact in the world's most extraordinary objects. Auctioneers since 1744, today we offer a variety of innovative art-related services, including the brokerage of private art sales, the brokerage of private jewelry sales through our Sotheby's Diamonds brand, exclusive private selling exhibitions at our S|2 galleries, art-related financing, and art advisory services, as well as retail wine locations in New York and Hong Kong. Our operations are organized under two segments—the Agency segment and the Finance segment, which does business as and is referred to in this report as Sotheby's Financial Services (or "SFS"). Thomas S. Smith, Jr, Sotheby's Chief Executive Officer, is our chief operating decision maker. Mr. Smith regularly evaluates financial information about each of our segments in deciding how to allocate resources and assess performance. The performance of each segment is measured based on segment income before taxes, which excludes the unallocated items highlighted in the reconciliation below.

Through our Agency segment, we accept property on consignment, stimulate buyer interest through professional marketing techniques, and match sellers (also known as consignors) to buyers through the auction or private sale process. Prior to offering a work of art for sale, we perform due diligence activities to authenticate and determine the ownership history of the property being sold. To a much lesser extent, Agency segment activities also include the sale of artworks that are principally acquired as a consequence of the auction process, and RM Sotheby's, an equity investee that operates as an auction house for investment-quality automobiles. The Agency segment is an aggregation of the auction, private sale, and other related activities conducted by our operating segments in the Americas, Europe, and Asia, which have similar economic characteristics and are similar in their services, customers, and the manner in which their services are provided.

SFS is an art financing company that operates as a niche lender with the ability to tailor attractive financing packages for clients who wish to obtain immediate access to liquidity from their art assets. SFS deploys a unique combination of art expertise, skill in international law and finance, and access to capital to provide art collectors and dealers with financing secured by their works of art, allowing them to unlock the value in their collections.

Art Agency, Partners (“AAP”), through which we offer art advisory services, provides art collectors with strategic guidance on collection identity and development, acquisitions, and short and long-term planning, and provides advice to artists and artists' estates. AAP was acquired on January 11, 2016 (see Note 19). Our advisory services are classified within All Other for segment reporting purposes, along with our retail wine business, brand licensing activities, the results from certain equity method investments (see Note 10), and sales of the remaining inventory of Noortman Master Paintings, an art dealer that was owned and operated by us from its acquisition in 2006 until its closure in December 2013.

The following table presents our segment information for the three and six months ended June 30, 2017 and 2016 (in thousands of dollars):

4. Receivables

Accounts Receivable (Net)—Through our Agency segment, we accept property on consignment and match sellers, also known as consignors, to buyers through the auction or private sale process. Following an auction or private sale, we invoice the buyer for the purchase price of the property (including our commission, as well as any applicable taxes and royalties), collect payment from the buyer, and remit to the consignor the net sale proceeds after deducting our commissions, expenses and applicable taxes and royalties.

Under our standard auction payment terms, the purchase price is due from the buyer no more than 30 days after the sale date, with the net proceeds due to the consignor 35 days from the sale date. For private sales, payment from the buyer is typically due on the sale date, with the net sale proceeds due to the consignor shortly thereafter. We also sometimes provide extended payment terms to an auction or private sale buyer. For auctions, the extent to which extended payment terms are provided can vary considerably from selling season to selling season. Extended payment terms typically extend the payment due date to a date that is no longer than one year from the sale date. In limited circumstances, the payment due date may be extended to a date that is beyond one year from the sale date. When providing extended payment terms, we attempt to match the timing of cash receipt from the buyer with the timing of our payment to the consignor, but are not always successful in doing so. All extended payment term arrangements are approved by management under our internal corporate governance policy.

In the limited circumstances when the buyer's payment due date is extended to a date that is beyond one year from the sale date, if the consignor does not provide matched payment terms (i.e., we pay the consignor before receiving payment from the buyer), the receivable balance is reclassified from Accounts Receivable to Notes Receivable on our Condensed Consolidated Balance Sheets. As of June 30, 2017, December 31, 2016, and June 30, 2016, Notes Receivable within the Agency segment included $2.6 million, $7.5 million, and $12.2 million, respectively, of such balances that have been reclassified from Accounts Receivable. See discussion of Agency segment Notes Receivable below.

Under the standard terms and conditions of our auction and private sales, we are not obligated to pay the consignor for property that has not been paid for by the buyer. If a buyer defaults on payment, the sale may be cancelled, and the property will be returned to the consignor. Alternatively, the consignor may reoffer the property at one of our future auctions or negotiate a private sale with us acting as their agent. In certain instances, and subject to management approval under our internal corporate governance policy, we may pay the net sale proceeds to the consignor before payment is collected from the buyer and/or we may allow the buyer to take possession of the property before making payment. In situations when the buyer takes possession of the property before making payment, we are liable to the seller for the net sales proceeds whether or not the buyer makes payment. As of June 30, 2017, December 31, 2016, and June 30, 2016, Accounts Receivable (net) included $85.3 million, $90.1 million, and $104.5 million, respectively, related to situations when we paid the consignor all or a portion of the net sales proceeds before payment was collected from the buyer. As of June 30, 2017, December 31, 2016, and June 30, 2016, Accounts Receivable (net) also included $33.4 million, $76.3 million, and $33.9 million, respectively, related to situations when we allowed the buyer to take possession of the property before making payment.

Notes Receivable (Sotheby's Financial Services)—SFS makes term loans secured by artworks that are not presently intended for sale, allowing us to establish or enhance mutually beneficial relationships with art collectors. Term loans may also generate future auction or private sale consignments and/or purchases. In certain situations, term loans are made to refinance receivables generated by the auction and private sale purchases of our clients. Term loans normally have initial maturities of up to two years and typically carry a variable market rate of interest. To a much lesser extent, SFS also makes consignor advances secured by artworks that are contractually committed, in the near term, to be offered for sale through our Agency segment. Consignor advances allow sellers to receive funds upon consignment for an auction or private sale that will occur up to one year in the future and normally have short-term maturities.

The lending activities of SFS are predominantly funded with borrowings drawn from a dedicated revolving credit facility. To a lesser extent, cash balances are also used to fund a portion of the loans made by SFS, as appropriate. See Note 7 for information related to the dedicated revolving credit facility for SFS.

11

As of June 30, 2017, December 31, 2016, and June 30, 2016, the net Notes Receivable balance of SFS was $651.4 million, $675.1 million, and $629.7 million, respectively. As of June 30, 2017, December 31, 2016, and June 30, 2016, the total net Notes Receivable balance of SFS included $85.6 million, $88.7 million, and $104.4 million, respectively, of term loans issued by SFS to refinance client auction and private sale purchases. For the six months ended June 30, 2017 and 2016, SFS issued $3.8 million and $9.3 million, respectively, of such loans. These loans are accounted for as non-cash transfers between Accounts Receivable (net) and Notes Receivable (net) and are, therefore, not reflected as the funding of Notes Receivable within Investing Activities in our Condensed Consolidated Statements of Cash Flows. Upon repayment, the cash received in settlement of such Notes Receivable is classified within Operating Activities in our Condensed Consolidated Statements of Cash Flows. For the six months ended June 30, 2017 and 2016, such repayments totaled $6.9 million and $13.7 million, respectively.

The repayment of secured loans can be adversely impacted by a decline in the art market in general or in the value of the collateral, which is concentrated within certain collecting categories. In addition, in situations when there are competing claims on the collateral and/or when a borrower becomes subject to bankruptcy or insolvency laws, our ability to realize on our collateral may be limited or delayed.

We aim to mitigate the risk associated with a potential devaluation in our collateral by targeting a 50% loan-to-value ("LTV") ratio (i.e., the principal loan amount divided by the low auction estimate of the collateral). However, loans may also be made with LTV ratios between 51% and 60%, and, in rare circumstances, loans may be made at an initial LTV ratio higher than 60%. The revolving credit facility for SFS permits borrowings of up to 85% of the portion of any loan that does not exceed a 60% LTV ratio.

The LTV ratio of certain loans may increase above the 50% target due to a decrease in the low auction estimates of the collateral. The revaluation of term loan collateral is performed by our specialists on an annual basis or more frequently if there is a material change in the circumstances related to the loan, the value of the collateral, the disposal plans for the collateral, or if an event of default occurs. We believe that the LTV ratio is a critical credit quality indicator for the secured loans made by SFS.

The table below provides the aggregate LTV ratio for the SFS loan portfolio as of June 30, 2017, December 31, 2016, and June 30, 2016 (in thousands of dollars):

	June 30, 2017			December 31, 2016			June 30, 2016

Low auction estimate of collateral	$	1,445,847		$	1,405,856		$	1,296,760
Aggregate LTV ratio	45		%	48		%	49		%

The table below provides the aggregate LTV ratio for secured loans made by SFS with an LTV ratio above 50% as of June 30, 2017, December 31, 2016, and June 30, 2016 (in thousands of dollars):

	June 30, 2017			December 31, 2016			June 30, 2016

We consider a loan to be past due when principal payments are not paid by the contractual maturity date. Typically, a loan becomes past due only for a short period of time during which either the loan is renewed or collateral is sold to satisfy the borrower's obligations. As of June 30, 2017, $108.6 million of the net Notes Receivable balance was past due, of which $41.4 million was more than 90 days past due. The collateral securing these past due loans has a low auction estimate of approximately $232.5 million resulting in an LTV ratio of approximately 47%. We are continuing to accrue interest on all past due loans. In consideration of expected loan renewals, loan payments, and $33.3 million in collateral sales to date related to loans that are more than 90 days past due for which the proceeds have not yet been collected from the buyer, as well as the value of the remaining collateral and our current collateral disposal plans, we believe that the principal and interest amounts owed for these past due loans will be collected.

A non-accrual loan is a loan for which future Finance revenue is not recorded due to our determination that it is probable that future interest on the loan is not collectible. Any cash receipts subsequently received on non-accrual loans are first applied to reduce the recorded principal balance of the loan, with any proceeds in excess of the principal balance then applied to interest owed by the borrower. The recognition of Finance revenue may resume on a non-accrual loan if sufficient additional collateral is provided by the borrower or if we become aware of other circumstances that indicate that it is probable that the borrower will make future interest payments on the loan. As of June 30, 2017, there were no non-accrual loans outstanding. As of December 31, 2016 and June 30, 2016, there was a $0.2 million non-accrual loan outstanding. This loan was written-off in the second quarter of 2017.

A loan is considered to be impaired when we determine that it is probable that a portion of the principal and interest owed by the borrower will not be recovered after taking into account the estimated realizable value of the collateral securing the loan, as well as the ability of the borrower to repay any shortfall between the value of the collateral and the amount of the loan. If a loan is considered to be impaired, Finance revenue is no longer recognized and bad debt expense is recorded for any principal or accrued interest that is deemed uncollectible. As of June 30, 2017, December 31, 2016, and June 30, 2016, there were no impaired loans outstanding.

During the period January 1, 2017 to June 30, 2017, activity related to the Allowance for Credit Losses was as follows (in thousands of dollars):

Allowance for credit losses as of January 1, 2017	$	1,270
Change in loan loss provision	20
Allowance for credit losses as of June 30, 2017	$	1,290

As of June 30, 2017, unfunded commitments to extend additional credit through SFS were approximately $26 million.

Notes Receivable (Agency Segment)—We are obligated under the terms of certain auction guarantees to advance a portion of the guaranteed amount prior to the auction. Such auction guarantee advances are recorded on our Condensed Consolidated Balance Sheets within Notes Receivable (net). As of June 30, 2017 and June 30, 2016, there were no auction guarantee advances outstanding. As of December 31, 2016, there were $1 million of auction guarantee advances outstanding. See Note 16 for additional information related to auction guarantees.

13

As discussed above, in the limited circumstances when the payment due date for an auction or private sale receivable is extended to a date that is beyond one year from the sale date, if the consignor does not provide matched payment terms, the receivable balance is reclassified from Accounts Receivable (net) to Notes Receivable (net) on our Condensed Consolidated Balance Sheets. As of June 30, 2017 and December 31, 2016, Notes Receivable (net) within the Agency segment included $2.6 million and $7.5 million, respectively, of such amounts reclassified from Accounts Receivable (net), against which we hold approximately $3.1 million of collateral. As of June 30, 2016, Notes Receivable (net) within the Agency segment included $12.2 million of such reclassified amounts, against which we held $6.6 million of collateral. These Notes Receivable are accounted for as non-cash transfers between Accounts Receivable (net) and Notes Receivable (net) and are, therefore, not reflected as the funding of Notes Receivable within Investing Activities in our Condensed Consolidated Statements of Cash Flows. Upon repayment, the cash received in settlement of such Notes Receivable is classified within Operating Activities in our Condensed Consolidated Statements of Cash Flows. For the six months ended June 30, 2017 and 2016, such repayments totaled $5 million and $7.5 million, respectively.

Under certain circumstances, we provide loans to certain art dealers to finance the purchase of works of art. In these situations, we acquire a partial ownership interest or a security interest in the purchased property in addition to providing the loan. Upon the eventual sale of the property acquired, the loan is repaid. As of June 30, 2017, December 31, 2016, and June 30, 2016, such loans totaled $3.8 million, $3.8 million, and $4.1 million, respectively. We are no longer accruing interest with respect to one of these loans with a balance of $2.1 million, but management believes that this balance is collectible.

Notes Receivable (Other)—In the second quarter of 2013, we sold our interest in an equity method investee for $4.3 million. The sale price was funded by an upfront cash payment of $0.8 million and the issuance of a $3.5 million unsecured loan. This loan had a variable market rate of interest, required monthly payments during the loan term, and was initially scheduled to mature in December 2018. As of December 31, 2016 and June 30, 2016, the carrying value of this loan was approximately $2.1 million and $2.3 million, respectively. The entire remaining balance of the loan was repaid in the second quarter of 2017.

6. Defined Benefit Pension Plan

We sponsor a defined benefit pension plan in the U.K. (the "U.K. Pension Plan"). Effective April 1, 2004, participation in the U.K. Pension Plan was closed to new employees. On April 30, 2016, after the completion of a statutory consultation process, the U.K. Pension Plan was closed to accrual of future service costs for active participants, who became participants in a defined contribution plan. 

For the three and six months ended June 30, 2017 and 2016, the components of the net credits related to the U.K. Pension Plan were as follows (in thousands of dollars):

7. Debt

Revolving Credit Facilities—We are party to a credit agreement with an international syndicate of lenders, which provides for separate dedicated revolving credit facilities for the Agency segment (the "Agency Credit Facility") and SFS (the "SFS Credit Facility") (the "Credit Agreement"). The maturity date of the Credit Agreement is August 22, 2020.

The Agency Credit Facility and the SFS Credit Facility are asset-based revolving credit facilities which may be used primarily for the working capital and other general corporate needs of each segment, including for the funding of SFS loans. The Credit Agreement allows the proceeds from borrowings under each of the revolving credit facilities to be transferred between the Agency segment and SFS.

The maximum aggregate borrowing capacity of the Credit Agreement, which is subject to a borrowing base, is approximately $1.335 billion, with $300 million committed to the Agency segment and $1.035 billion committed to SFS. The borrowing capacity of the Agency Credit Facility includes a $50 million incremental revolving credit facility with higher advance rates against certain assets and higher commitment and borrowing costs (the "Incremental Facility"). On July 25, 2017, the maturity date of the Incremental Facility was extended by one year to August 22, 2018, in accordance with the terms of the Credit Agreement. This maturity date may be extended for an additional 365 days on an annual basis with the consent of the lenders who agree to extend their commitments under the Incremental Facility.

The Credit Agreement has a sub-limit of $400 million for foreign currency borrowings, with up to $50 million available for foreign currency borrowings under the Agency Credit Facility and up to $350 million available for foreign currency borrowings under the SFS Credit Facility. The Credit Agreement also includes an accordion feature, which allows us to seek an increase to the borrowing capacity of the Credit Agreement until February 23, 2020 by an amount not to exceed $150 million in the aggregate. Though new commitments would need to be obtained, the uncommitted accordion feature permits us to seek an increase to the aggregate commitments of the Credit Agreement under an expedited arrangement process.

The borrowing base under the Agency Credit Facility is determined by a calculation that is primarily based upon a percentage of the carrying values of certain auction guarantee advances (see Note 4), a percentage of the carrying value of certain inventory, a percentage of the carrying value of certain extended payment term receivables arising from auction or private sale transactions (see Note 4), and the fair value of certain of our trademarks. The borrowing base under the Incremental Facility is determined by a calculation that is based on a percentage of the carrying values of certain inventory and the fair value of certain of our trademarks. The borrowing base under the SFS Credit Facility is determined by a calculation that is primarily based upon a percentage of the carrying value of certain SFS loans (see Note 4) and the fair value of certain of our trademarks.

16

The obligations under the Credit Agreements are cross-guaranteed and cross-collateralized. Domestic borrowers are jointly and severally liable for all obligations under the Credit Agreement and, subject to certain limitations, borrowers in the U.K. and Sotheby's Hong Kong Limited, are jointly and severally liable for all obligations of the foreign borrowers under the Credit Agreement. In addition, the obligations of the borrowers under the Credit Agreement are guaranteed by certain of their subsidiaries. Our obligations under the Credit Agreement are secured by liens on all or substantially all of the personal property of the entities that are borrowers and guarantors under the Credit Agreement.

The Credit Agreement contains certain customary affirmative and negative covenants including, but not limited to, limitations on capital expenditures, a $600 million limitation on net outstanding auction guarantees (i.e., auction guarantees less the impact of related risk and reward sharing arrangements), and limitations on the use of proceeds from borrowings under the Credit Agreement.

The Credit Agreement does not limit dividend payments and common stock repurchases provided that, both before and after giving effect thereto: (i) there are no events of default, (ii) the aggregate available borrowing capacity equals or exceeds $100 million, and (iii) the Liquidity Amount, as defined in the Credit Agreement, equals or exceeds $200 million. The Credit Agreement also contains certain financial covenants, which are only applicable during certain defined compliance periods. These financial covenants were not applicable for the twelve month period ended June 30, 2017.

Since August 2009, we have incurred aggregate fees of approximately $21.7 million in conjunction with the establishment of and subsequent amendments to the Credit Agreement. These fees are being amortized on a straight-line basis through the August 22, 2020 maturity date of the Credit Agreement. As of June 30, 2017, $6.8 millionofsuch unamortized fees are included within Other Long-Term Assets on our Condensed Consolidated Balance Sheets.

The following tables summarize information related to the Credit Agreement as of and for the periods ended June 30, 2017, December 31, 2016, and June 30, 2016 (in thousands of dollars):

Total Long-Term Debt, net	$	563,762		$	598,941		$	601,944

See the captioned sections below for information related to the York Property Mortgage and the 2022 Senior Notes.

York Property Mortgage—On February 6, 2009, we purchased the land and building located at 1334 York Avenue, New York, New York (the "York Property") from RFR Holding Corp. ("RFR") for a purchase price of $370 million. The York Property is home to our sole North American auction salesroom and principal North American exhibition space, including S|2, our private sale exhibition gallery. The York Property is also home to the U.S. operations of SFS, as well as our corporate offices.

18

We financed the $370 million purchase price through an initial $50 million cash payment made in conjunction with the signing of the related purchase and sale agreement on January 11, 2008, an $85 million cash payment made when the purchase was consummated on February 6, 2009, and the assumption of a $235 million mortgage that carried an initial annual rate of interest of approximately 5.6% (the "Original York Property Mortgage"). The Original York Property Mortgage was due to mature on July 1, 2035, but had an optional pre-payment date of July 1, 2015, after which the annual rate of interest was scheduled to increase to 10.6%.

On July 1, 2015, we entered into a seven-year, $325 million mortgage loan (the "York Property Mortgage") to refinance the Original York Property Mortgage. After the repayment of the Original York Property Mortgage and the funding of all closing costs, reserves, and expenses, we received net cash proceeds of approximately $98 million. The York Property Mortgage bears interest based on the one-month LIBOR rate (the "LIBOR rate") plus a spread of 2.25% and is being amortized based on a 25-year mortgage-style amortization schedule over its seven-year term. On June 21, 2017, the York Property Mortgage was amended to reduce the minimum net worth that Sotheby's is required to maintain from $425 million to $325 million in order to provide continued flexibility regarding potential future share repurchases. In conjunction with this amendment, on July 3, 2017, we made a partial prepayment of $32 million to reduce the outstanding principal balance of the York Property Mortgage, and agreed to make annual prepayments beginning in July 2018 and continuing through July 2021 that are not to exceed $25 million in the aggregate during that period. The $32 million payment made on July 3, 2017 was funded with $25 million from existing cash balances and $7 million from a restricted cash management account associated with the York Property Mortgage. Any prepayments made during the period July 2018 to July 2021 will also be funded from the restricted cash management account. See below for information related to the cash management account associated with the York Property Mortgage.

In connection with the York Property Mortgage, we entered into interest rate protection agreements secured by the York Property, consisting of a two-year interest rate swap effective as of July 1, 2015 and a five-year interest rate collar effective as of July 1, 2017. In conjunction and concurrent with the June 2017 amendment to the York Property Mortgage, the notional amount of the interest rate collar was reduced by $57 million to reflect: (i) the $32 million prepayment made on the York Property Mortgage on July 3, 2017 and (ii) potential annual prepayments of $6.25 million each beginning in July 2018 and continuing through July 2021. See Note 8 for additional information related to the interest rate protection agreements.

The York Property, the York Property Mortgage, and the related interest rate protection agreements are held by 1334 York, LLC (the "LLC"), a separate legal entity of Sotheby's that maintains its own books and records and whose results are ultimately consolidated into our Condensed Consolidated Financial Statements. The LLC is the sole owner and lessor of the York Property. The LLC presently leases the York Property to Sotheby's, Inc., which is also controlled by Sotheby's. The assets of the LLC are not available to satisfy the obligations of our other affiliates or any other entity.

The loan agreement governing the York Property Mortgage contains the following financial covenants, which are subject to additional terms and conditions as provided in the underlying loan agreement:

• As of July 1, 2020, the LTV ratio (i.e., the principal balance of the York Property Mortgage divided by the appraised value of the York Property) may not exceed 65% (the "Maximum LTV") based on the then-outstanding principal balance of the York Property Mortgage. If the LTV ratio exceeds the Maximum LTV, the LLC may, at its option, post cash or a letter of credit or pay down the York Property Mortgage without any prepayment penalty or premium, in an amount that will cause the LTV ratio not to exceed the Maximum LTV.

• At all times during the term of the York Property Mortgage, the Debt Yield will not be less than 8.5% (the "Minimum Debt Yield"). The Debt Yield is calculated by dividing the annual net operating income of the LLC, which primarily consists of lease income from Sotheby's, Inc. (calculated on a cash basis), by the outstanding principal balance of the York Property Mortgage. If the Debt Yield falls below the Minimum Debt Yield, the LLC has the option to post cash or a letter of credit or prepay the York Property Mortgage without any prepayment penalty or premium, in an amount that will cause the Debt Yield to exceed the Minimum Debt Yield.

19

• If Sotheby's corporate credit rating from Standard & Poor’s Rating Services ("S&P") is downgraded to "BB-", the lender may require that the LLC establish cash management accounts (the "Cash Management Accounts") under the lender's control for potential monthly debt service, insurance, and tax payments. If the rating is downgraded to "B+" or "B", the lender may require the LLC to deposit a certain amount of debt service into the Cash Management Accounts (approximately 6 and 12 months of debt service, respectively). If the rating is downgraded to lower than "B", the LLC must make principal payments on the mortgage such that the LTV ratio does not exceed 65%. On February 9, 2016, our corporate credit rating from S&P was downgraded to "BB-" from "BB". As a result, a Cash Management Account was established under the control of the lender for monthly debt service, insurance, and tax payments. The lender will retain any excess cash after debt service, insurance, and taxes as security. As of June 30, 2017, December 31, 2016, and June 30, 2016, the Cash Management Account had a balance of $7.4 million, $4.6 million, and $2.3 million, respectively, which is reflected within Restricted Cash on our Condensed Consolidated Balance Sheets. On July 3, 2017, $7 million from the Cash Management Account was used to fund a portion of the $32 million prepayment of the York Property Mortgage discussed above.

• Prior to June 21, 2017, Sotheby's was required to maintain a net worth of at least $425 million, subject to a cure period. As discussed above, on June 21, 2017, the York Property Mortgage was amended to reduce this $425 million requirement to $325 million.

As of June 30, 2017, the fair value of the York Property Mortgage approximated its book value due to the variable interest rate associated with the mortgage. The fair value measurement is considered to be a Level 2 fair value measurement in the fair value hierarchy as per ASC 820, Fair Value Measurements.

2022 Senior Notes—On September 27, 2012, we issued $300 million aggregate principal amount of 5.25% Senior Notes, due October 1, 2022 (the "2022 Senior Notes"). The 2022 Senior Notes were offered only to qualified institutional buyers in accordance with Rule 144A and to non-U.S. Persons under Regulation S under the Securities Act of 1933, as amended (the "Securities Act"). Holders of the 2022 Senior Notes do not have registration rights, and the 2022 Senior Notes have not been and will not be registered under the Securities Act.

The net proceeds from the issuance of the 2022 Senior Notes were approximately $294.6 million, after deducting fees paid to the initial purchasers, and were principally used to retire $80 million of unsecured debt that was due in June 2015 and $182 million of convertible debt that was due in June 2013.

The 2022 Senior Notes are guaranteed, jointly and severally, on a senior unsecured basis by certain of our existing and future domestic subsidiaries to the extent and on the same basis that such subsidiaries guarantee borrowings under the Credit Agreement. Interest on the 2022 Senior Notes is payable semi-annually in cash on April 1 and October 1 of each year.

We may redeem the 2022 Senior Notes, in whole or in part, on or after October 1, 2017, at specified redemption prices set forth in the underlying indenture, plus accrued and unpaid interest to, but excluding, the redemption date. Prior to October 1, 2017, we may redeem the 2022 Senior Notes, in whole or in part, at a redemption price equal to 100% of the principal amount to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date, plus a premium equal to the greater of 1% of the principal amount of the 2022 Senior Notes and a make-whole premium (as defined in the underlying indenture). The 2022 Senior Notes are not callable by holders unless we are in default under the terms of the underlying indenture.

As of June 30, 2017, the $300 million principal amount of the 2022 Senior Notes had a fair value of approximately $301.5 million based on a broker quoted price derived via a pricing model using observable and unobservable inputs. As such, this fair value measurement is considered to be a Level 3 fair value measurement in the fair value hierarchy as per ASC 820.

Future Principal and Interest Payments—The aggregate future principal and interest payments due under the Credit Agreement, the York Property Mortgage, and the 2022 Senior Notes during the five-year period after June 30, 2017 are as follows (in thousands of dollars):

Period	Amount
July 2017 to June 2018	$	65,337
July 2018 to June 2019	$	39,362
July 2019 to June 2020	$	39,203
July 2020 to June 2021	$	570,569
July 2021 to June 2022	$	38,927

See the captioned sections below for information related to derivative financial instruments designated as cash flow hedges or as net investment hedges.

Derivative Financial Instruments Designated as Cash Flow Hedges—On July 1, 2015, we entered into a seven-year, $325 million mortgage loan to refinance the previous mortgage on the York Property. The York Property Mortgage bears interest based on the one-month LIBOR rate plus a spread of 2.25% and is being amortized based on a 25-year mortgage-style amortization schedule over its seven-year term. On June 21, 2017, the York Property Mortgage was amended to reduce the minimum net worth that Sotheby's is required to maintain from $425 million to $325 million in order to provide continued flexibility regarding potential future share repurchases. In conjunction with this amendment, on July 3, 2017, we made a partial prepayment of $32 million to reduce the outstanding principal balance of the York Property Mortgage, and agreed to make annual prepayments beginning in July 2018 and continuing through July 2021 that are not to exceed $25 million in the aggregate during that period. The $32 million payment made on July 3, 2017 was funded with $25 million from existing cash balances and $7 million from a restricted cash management account related to the mortgage. Any prepayments made during the period July 2018 to July 2021 will also be funded from the restricted cash management account. See Note 7 for information on the restricted cash management account related to the York Property Mortgage.

In connection with the York Property Mortgage, we entered into interest rate protection agreements secured by the York Property, consisting of a two-year interest rate swap (the "Mortgage Swap"), effective as of July 1, 2015, and a five-year interest rate collar (the "Mortgage Collar"), effective as of July 1, 2017. These interest rate protection agreements effectively fix the LIBOR rate on the York Property Mortgage at an annual rate equal to 0.877% for the first two years, and then at an annual rate of no less than 1.917%, but no more than 3.75%, for the remainder of the seven-year term. After taking into account the interest rate protection agreements, the annual interest rate for the first two years of the York Property Mortgage was approximately 3.127% and then will be between a floor of 4.167% and a cap of 6% for the remaining seven-year term.

23

In conjunction and concurrent with the June 2017 amendment to the York Property Mortgage, the notional amount of the Mortgage Collar was reduced by $57 million to reflect: (i) the $32 million prepayment made on the York Property Mortgage on July 3, 2017 and (ii) potential annual prepayments of $6.25 million each beginning in July 2018 and continuing through July 2021. The reduced notional amount of the Mortgage Collar relates to the previously forecasted interest payments that are no longer probable of occurring as a result of the June 2017 amendment to the York Property Mortgage. This reduction in the notional amount of the Mortgage Collar resulted in a $0.6 million (net of tax) reclassification from Accumulated Other Comprehensive Loss into Net Income in the second quarter of 2017.

As of June 30, 2017, the notional value of the Mortgage Swap was $311 million and the notional value of the Mortgage Collar was $278.3 million. As of June 30, 2017, the Mortgage Swap and the Mortgage Collar each have a notional amount that is no greater than the applicable forecasted principal balance of the York Property Mortgage. The York Property, the York Property Mortgage, and the related interest rate protection agreements are held by 1334 York, LLC, a separate legal entity of Sotheby's that maintains its own books and records and whose results are ultimately consolidated into our financial statements.

On November 21, 2016, we entered into a two-year interest rate swap agreement (the “SFS Swap”) to eliminate the variability in expected cash outflows associated with the one-month LIBOR indexed interest payments owed on $63 million of SFS Credit Facility borrowings. As of June 30, 2017, the notional value of the SFS Swap was $63 million. See Note 7 for additional information related to the SFS Credit Facility.

At their inception, the Mortgage Swap, the Mortgage Collar, and the SFS Swap (collectively, the "Cash Flow Hedges") were each individually designated as cash flow hedges of the risk associated with the variability in expected cash outflows related to the one-month LIBOR-indexed interest payments owed on their respective debt instruments. Accordingly, to the extent that each of the Cash Flow Hedges is effective, any unrealized gains and losses related to changes in their fair value are recorded to Accumulated Other Comprehensive Loss on our Condensed Consolidated Balance Sheets and then reclassified to Interest Expense in our Condensed Consolidated Income Statements in the same period that interest expense related to the underlying debt instruments is recorded. Any hedge ineffectiveness is immediately recognized in Net Income. In addition, if any of the forecasted transactions associated with the Cash Flow Hedges are no longer probable of occurring, any related amounts previously recorded in Accumulated Other Comprehensive Loss on our Condensed Consolidated Balance Sheets would be immediately reclassified into Net Income. As discussed above, certain previously forecasted interest payments associated with the Mortgage Collar became no longer probable of occurring in the second quarter of 2017 and, as a result, $0.6 million (net of tax) of the amount previously recorded in Accumulated Other Comprehensive Loss was immediately reclassified into Net Income.

Management performs a quarterly assessment to determine whether each of the Cash Flow Hedges continues to be highly effective in hedging the risk associated with the variability in expected cash outflows related to the one-month LIBOR-indexed interest payments on their respective debt instruments. As of June 30, 2017, each of the Cash Flow hedges, including the Mortgage Collar, as amended, is expected to continue to be highly effective in hedging the risk associated with the variability in expected cash outflows related to the one-month LIBOR-indexed interest payments on their respective debt instruments.

The assets and liabilities associated with the Cash Flow Hedges have been designated as Level 2 fair value measurements within the fair value hierarchy provided by ASC 820. Level 2 fair value measurements have pricing inputs other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date. Level 2 fair value measurements may be determined through the use of models or other valuation methodologies. The fair value of the Mortgage Swap is based on a discounted cash flow methodology using the contractual terms of the instrument and observable LIBOR-curve rates that are consistent with the timing of the interest payments related to the York Property Mortgage. The fair value of the Mortgage Collar is based on an option pricing model using observable LIBOR-curve rates for each forecasted monthly settlement, with the projected cash flows discounted using the contractual terms of the instrument. The fair value of the SFS Swap is based on a discounted cash flow methodology using the contractual terms of the instrument and observable LIBOR-curve rates that are consistent with the timing of the interest payments related to the SFS Credit Facility.

Derivative Financial Instruments Designated as Net Investment Hedges—We are exposed to variability in the U.S. Dollar equivalent of the net investments in our foreign subsidiaries and, by extension, the U.S. Dollar equivalent of any foreign earnings repatriated to the U.S. due to potential changes in foreign currency exchange rates. As a result, we regularly enter into foreign currency forward exchange contracts to hedge the net investments in our foreign subsidiaries from which we expect to repatriate earnings to the U.S. As of June 30, 2017, the aggregate notional value of our outstanding net investment hedge contracts was $49.7 million.

We use the forward rate method to assess the effectiveness of our net investment hedges. Under the forward rate method, if both the notional amount of the derivative designated as a hedge of a net investment in a foreign subsidiary equals the portion of the net investment designated as being hedged and the derivative relates solely to the foreign exchange rate between the functional currency of the hedged net investment and the investor’s functional currency, then all changes in fair value of the derivative are reported in the cumulative translation adjustment accounts within Accumulated Other Comprehensive Loss on our Condensed Consolidated Balance Sheets.

The foreign currency forward exchange contracts designated as net investment hedges are considered Level 2 fair value measurements within the fair value hierarchy provided by ASC 820. Level 2 fair value measurements have pricing inputs other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value may be determined through the use of models or other valuation methodologies. The fair value of these foreign currency forward exchange contracts is based on the estimated amount to settle the contracts using applicable market exchange rates as of the balance sheet date.

Derivative Financial Instruments Not Designated as Hedging Instruments—We also utilize forward contracts to hedge cash flow exposures related to foreign currency exchange rate movements arising from short-term foreign currency denominated intercompany balances and, to a much lesser extent, foreign currency denominated client payable balances, as well as foreign currency denominated auction guarantee obligations. Such forward exchange contracts are typically short-term with settlement dates less than six months from their inception. These instruments are not designated as hedging instruments for accounting purposes. Accordingly, changes in the fair value of these instruments are recognized in our Condensed Consolidated Income Statements in Non-Operating Income.

As of June 30, 2017, the notional value of outstanding forward exchange contracts not designated as hedging instruments was $197.9 million. Notional values do not quantify risk or represent our assets or liabilities, but are used to calculate cash settlements under outstanding forward exchange contracts. We are exposed to credit-related risks in the event of nonperformance by the counterparties to our outstanding forward exchange contracts that are not designated as hedging instruments. We do not expect either of these counterparties to fail to meet their obligations, given their high short-term (A1/P1) credit ratings. As of June 30, 2017, December 31, 2016, and June 30, 2016 the aggregate fair value of these contracts represented liabilities of $1.4 million, $3.6 million, and $3.7 million, respectively, which were recorded on our Condensed Consolidated Balance Sheets within Accounts Payable and Accrued Liabilities.

9. Sale of Pink Diamond

Our reported inventory balances include a Fancy Vivid Pink Diamond (the "Pink Diamond") with a carrying value of $68.4 million. In the second quarter of 2016, we sold an undivided legal and beneficial 50% ownership interest in the Pink Diamond for $34.2 million in cash. In April 2017, at our Magnificent Jewels and Jadeite Sale in Hong Kong (the "Auction"), the Pink Diamond was sold for a total purchase price of approximately $71.2 million (the "Purchase Price"). The purchaser of the Pink Diamond, who is one of the largest jewelery retailers in the world, is legally obligated to pay the Purchase Price by no later than April 4, 2018.

Although the Auction occurred in the second quarter of 2017, the sale will not be recognized in our financial statements until we collect the Purchase Price and transfer title and possession of the Pink Diamond to the purchaser. Until that time, the Pink Diamond will continue to be reported on our balance sheet within Inventory at its $68.4 million carrying value, with the $34.2 million cash payment received in the second quarter of 2016 recorded within Other Current Liabilities. When payment is collected and the related revenue is recognized in our financial statements, the sale of the Pink Diamond will result in a gain of approximately $0.5 million, after taking into account the associated Cost of Inventory Sales of $70.7 million, which includes amounts due to our partner and other costs related to the sale.

12. Shareholders' Equity and Dividends

Common Stock Repurchase Program—The following table provides information regarding our common stock repurchase program for the six months ended June 30, 2017 and 2016 (in thousands, except for per share data):

	Six Months Ended
	June 30, 2017		June 30, 2016
Shares repurchased	740		10,989
Aggregate purchase price	$	33,940	$	282,205

As of June 30, 2017 and August 2, 2017, the remaining authorization from our Board of Directors under our common stock repurchase program was $6.3 million.

The timing of further share repurchases and the actual amount purchased will depend on a variety of factors including the market price of our common stock, general market and economic conditions, securities law requirements, and other corporate considerations. Repurchases may continue to be made pursuant to plans intended to comply with Rule 10b5-1 under the Exchange Act, which allows us to purchase our shares during periods when we otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods. The repurchase authorization does not require the purchase of a specific number of shares and is subject to suspension or termination by our Board of Directors at any time.

Special Dividend—On January 29, 2014, the Board of Directors declared a special dividend of $300 million ($4.34 per share) that was paid on March 17, 2014. In conjunction with this special dividend, approximately $11 million was accrued for dividend equivalents owed on share-based payments to employees, which was charged to retained earnings. For the six months ended June 30, 2017 and 2016, approximately $2 million and $1.4 million, respectively, of such accrued dividend equivalents were paid upon the vesting of the underlying awards.

14. Commitments and Contingencies

Compensation Arrangements—We are party to compensation arrangements with certain senior employees, which expire at various points between October 26, 2017 and January 11, 2021. Such arrangements may provide, among other benefits, for minimum salary levels and for compensation under our incentive compensation programs that is payable only if specified Company and individual goals are attained. Additionally, under certain circumstances, certain of these arrangements provide annual share-based payments, severance payments, and other cash compensation. The aggregate remaining commitment for salaries and other cash compensation related to these compensation arrangements, excluding any participation in our incentive compensation programs, was approximately $15.4 million as of June 30, 2017.

Tax Contingencies—We are subject to laws and regulations in many countries involving sales, use, value-added and other indirect taxes which are assessed by various governmental authorities and imposed on certain revenue-producing transactions between us and our clients. The application of these laws and regulations to our unique business and global client base, and the estimation of any related liabilities, is complex and requires a significant amount of judgment. We are generally not responsible for these indirect tax liabilities unless we fail to collect the correct amount of sales, value-added, or other indirect taxes. Failure to collect the correct amount of indirect tax on a transaction may expose us to claims from tax authorities and could require us to record a liability and corresponding charge to our income statement.

Legal Contingencies—We become involved in various claims and lawsuits incidental to the ordinary course of our business. We are required to assess the likelihood of any adverse judgments or outcomes related to these legal contingencies, as well as potential ranges of probable or reasonably possible losses. The determination of the amount of any losses to be recorded or disclosed as a result of these contingencies is based on a careful analysis of each individual exposure with, in some cases, the assistance of outside legal counsel. The amount of losses recorded or disclosed for such contingencies may change in the future due to new developments in each matter or a change in settlement strategy. While the impact of any one or more legal claims or proceedings could be material to our operating results in any period, we do not believe that the outcome of any of these pending claims or proceedings, individually or in the aggregate, will have a material adverse effect on our consolidated financial condition.

See Note 4 for information related to unfunded commitments to extend additional loans through SFS. See Note 7 for information related to debt commitments. See Note 15 for information related to income tax contingencies. See Note 16 for information related to auction guarantees. See Note 19 for information related to our commitment to make earn-out payments to the former principals of AAP. 

15. Uncertain Tax Positions

As of June 30, 2017, our liability for unrecognized tax benefits, excluding interest and penalties, was $20.4 million, representing a net increase of $0.9 million when compared to a liability of $19.5 million as of December 31, 2016. This net increase is primarily the result of the accrual of tax reserves related to transfer pricing and other U.S. federal and state and non-U.S. matters, partially offset by the expiration of the statute of limitations for certain tax years and the favorable settlement of tax audits. As of June 30, 2016, the liability for unrecognized tax benefits, excluding interest and penalties, was $19.5 million.

As of June 30, 2017, December 31, 2016, and June 30, 2016, the total amount of unrecognized tax benefits that, if recognized, would favorably affect our effective income tax rate was $9.6 million, $9.3 million, and $13.7 million, respectively. We believe it is reasonably possible that a decrease of $10.1 million in the balance of unrecognized tax benefits can occur within 12 months of the June 30, 2017 balance sheet date as a result of the expiration of statutes of limitations and the expected settlement of ongoing tax audits.

We are subject to taxation in the U.S., as well as in various U.S. state and foreign jurisdictions. As a result, we are subject to tax audits in these jurisdictions. We are currently under examination by various U.S. state and foreign taxing authorities. The earliest open tax year for the major jurisdictions in which we do business, which includes the U.S. (including various state and local jurisdictions), the U.K., and Hong Kong, is 2009.

We recognize interest expense and penalties related to unrecognized tax benefits as a component of Income Tax Expense. The accrual for such interest and penalties increased by $0.5 million for the six months ended June 30, 2017.

Our policy is to record interest expense related to sales, value added and other non-income based taxes as Interest Expense in our Condensed Consolidated Income Statements. Penalties related to such taxes are recorded as General and Administrative Expenses in our Condensed Consolidated Income Statements. Interest expense and penalties related to income taxes are recorded as a component of Income Tax Expense in our Condensed Consolidated Income Statements.

16. Auction Guarantees

From time-to-time in the ordinary course of our business, we will guarantee to a consignor a minimum sale price in connection with the sale of property at auction (an "auction guarantee"). If the property offered under the auction guarantee sells above the minimum guaranteed price, we are generally entitled to a share of the excess proceeds (the "overage"). In the event that the property sells for less than the minimum guaranteed price, we must perform under the auction guarantee by funding the difference between the sale price at auction and the amount of the auction guarantee (the "shortfall"). The amount of any shortfall recorded in our Condensed Consolidated Income Statements is reduced by any auction commissions earned on property sold under the auction guarantee. If any item of property offered under the auction guarantee does not sell, the amount of the auction guarantee must be paid, but we take ownership of the unsold property and may recover the amount paid through its future sale. In certain limited situations, if the guaranteed property fails to sell at auction or if the purchaser defaults, the consignor has the right to cancel the auction guarantee and retain the property. Depending on the mix of items subject to an auction guarantee, in advance of peak selling seasons, a small number of guaranteed items may represent a substantial portion of the aggregate amount of outstanding auction guarantees.

In situations when an item of guaranteed property does not sell and we take ownership of the property, it is recorded as Inventory on our Condensed Consolidated Balance Sheets at the lower of its cost (i.e., the amount paid under the auction guarantee) or our estimate of the property's net realizable value (i.e., the expected sale price upon its eventual disposition). The market for fine art, decorative art, and jewelry is not a highly liquid trading market. As a result, the valuation of property acquired as a result of failed auction guarantees is inherently subjective and its realizable value often fluctuates over time. Accordingly, the proceeds ultimately realized on the sale of previously guaranteed property may equal, exceed, or be less than the estimated net realizable value recorded as Inventory on our Condensed Consolidated Balance Sheets.

We may reduce our financial exposure under auction guarantees through contractual risk and reward sharing arrangements. Such auction guarantee risk and reward sharing arrangements include irrevocable bids and partner sharing arrangements. An irrevocable bid is an arrangement under which a counterparty commits to bid a predetermined price on the guaranteed property. If the irrevocable bid is not the winning bid, the counterparty is generally entitled to receive a share of the auction commission earned on the sale and/or a share of any overage. If the irrevocable bid is the winning bid, the counterparty may receive a fixed fee as compensation for providing the irrevocable bid. This fee may be netted against the counterparty's obligation to pay the full purchase price (i.e., the hammer price plus the applicable buyer's premium). In a partner sharing arrangement, a counterparty commits to fund: (i) a share of the difference between the sale price at auction and the amount of the auction guarantee if the property sells for less than the minimum guaranteed price or (ii) a share of the minimum guaranteed price if the property does not sell while taking ownership of a proportionate share of the unsold property. In exchange for accepting a share of the financial exposure under the auction guarantee, the counterparty in a partner sharing arrangement is generally entitled to receive a share of the auction commission earned if the property sells and/or a share of any overage.

The counterparties to our auction guarantee risk and reward sharing arrangements are typically major international art dealers or major art collectors. We could be exposed to losses in the event any of these counterparties do not perform according to the terms of these contractual arrangements.

Although irrevocable bid and partner sharing arrangements may be used to reduce the risk associated with auction guarantees, we may also enter into auction guarantees without securing such arrangements. In these circumstances, we could be exposed to deterioration in auction commission margins and/or auction guarantee losses if one or more of the guaranteed items fails to sell at its minimum guaranteed price. Furthermore, in such situations, our liquidity could be reduced.

Our credit agreement has a covenant that imposes a $600 million limitation on net outstanding auction guarantees (i.e., the aggregate financial exposure under outstanding auction guarantees less the impact of related risk and reward sharing arrangements). In addition to compliance with this covenant, significant auction guarantees and related risk and reward sharing arrangements are subject to approval by our Board of Directors.

As of June 30, 2017, we had outstanding auction guarantees totaling $9.8 million. Our financial exposure under these auction guarantees is reduced by irrevocable bids totaling $2.7 million. Each of the outstanding auction guarantees has a minimum guaranteed price that is within or below the range of the pre-sale auction estimates for the underlying property. The property related to these auction guarantees is being offered at auctions during the fourth quarter of 2017.

We are obligated under the terms of certain auction guarantees to advance all or a portion of the guaranteed amount prior to auction. As of June 30, 2017 and December 31, 2016, the estimated fair value of our obligation to perform under our outstanding auction guarantees totaled $0.4 million and $0.6 million, respectively, and is recorded within Accounts Payable and Accrued Liabilities on our Condensed Consolidated Balance Sheets. As of June 30, 2016, the liability related to our obligation to perform under our outstanding auction guarantees was not material.

31

As of August 2, 2017, we had outstanding auction guarantees totaling $17 million and, as of that date, our financial exposure was reduced by irrevocable bids totaling $2.7 million. Each of the auction guarantees outstanding as of August 2, 2017, had a minimum guaranteed price that was within or below the range of the pre-sale auction estimates for the underlying property. The property related to these auction guarantees is being offered at auctions in the fourth quarter of 2017. As of August 2, 2017, we have advanced $1.1 million of the total guaranteed amount.

17. Share-Based Payments

Share-Based Payments—Share-based payments made to employees include performance-based stock unit awards, market-based stock unit awards, restricted stock units, restricted shares, and stock options. Share-based payments are also made to members of our Board of Directors through the issuance of deferred stock units. A description of each of these share-based payments is provided below.

For the three and six months ended June 30, 2017 and 2016, compensation expense for share-based payments made to employees was reflected in the following accounts in our Condensed Consolidated Income Statements (in thousands of dollars):

	Three Months Ended June 30,					Six Months Ended June 30,
	2017		2016			2017		2016
Salaries and related costs	$	5,946	$	2,291		$	12,015	$	8,128
Voluntary separation incentive programs	—		(334		)	—		(640		)
Total share-based payment expense (pre-tax)	$	5,946	$	1,957		$	12,015	$	7,488
Total share-based payment expense (after-tax)	$	3,940	$	1,609		$	7,997	$	5,410

For the three and six months ended June 30, 2016, our Condensed Consolidated Income Statements include credits of ($0.3) million and ($0.6) million, respectively, related to the voluntary separation incentive programs enacted in the fourth quarter of 2015. These credits were the result of changes in our estimate of the number of performance-based stock units held by program participants that were expected to vest.

As discussed in Note 1, on January 1, 2017, we adopted ASU 2016-09, Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 requires, among other things, that all excess tax benefits and deficiencies resulting from the vesting of share-based payments be recorded in the statement of operations, whereas previous guidance generally permitted such items to be recorded in the equity section of the balance sheet provided that an adequate level of previously recorded excess tax benefits existed. This aspect of ASU 2016-09 was adopted on a prospective basis.

For the six months ended June 30, 2017, we recognized a $2.6 million excess tax benefit related to share-based payment in our Condensed Consolidated Income Statements. This tax benefit represents the amount by which the tax deduction resulting from the vesting of share-based payments in the period exceeded the tax benefit initially recognized in our Condensed Consolidated Financial Statements.

For the six months ended June 30, 2016, we recognized a ($1.3) million tax shortfall related to share-based payment. This tax shortfall represents the amount by which the tax deduction resulting from the vesting of share-based payments in the period was less than the tax benefit initially recognized in our Condensed Consolidated Financial Statements. As discussed above, prior to the adoption of ASU 2016-09 on January 1, 2017, such tax shortfalls were accounted for as a reduction to previously recorded excess tax benefits related to share-based payments within Additional Paid-in Capital on our Condensed Consolidated Balance Sheets.

As of June 30, 2017, unrecognized compensation expense related to the unvested portion of share-based payments to employees was $33.3 million. This compensation expense is expected to be amortized over a weighted-average period of approximately 2.4 years. We do not capitalize any compensation expense related to share-based payments to employees.

Restricted Stock Unit Plan—The Sotheby's Restricted Stock Unit Plan (as amended and restated, the "Restricted Stock Unit Plan") provides for the issuance of restricted stock units ("RSU's") and restricted shares to employees. Awards made under the Restricted Stock Unit Plan are subject to the approval of the Compensation Committee of our Board of Directors (the "Compensation Committee"). In making awards under the Restricted Stock Unit Plan, the Compensation Committee takes into account the nature of the services rendered by employees, their present and potential future contributions to Sotheby's success, and such other factors as the Compensation Committee in its discretion deems relevant.

32

RSU's and restricted shares issued under the Restricted Stock Unit Plan generally vest evenly over a three-year service period. Prior to vesting, holders of RSU's and restricted shares are entitled to receive non-forfeitable dividend equivalents and dividends, respectively, at the same rate as dividends are paid on our common stock (if and when such dividends are paid). Prior to vesting, holders of RSU's do not have voting rights, while holders of restricted shares have voting rights. RSU's and restricted shares may not be sold, assigned, transferred, pledged or otherwise encumbered until they vest.

Performance Share Units (or "PSU's") are RSU's that generally vest over three or four-year service periods, subject to the achievement of certain profitability targets (for awards granted prior to 2016) or certain return on invested capital ("ROIC") targets (for awards granted beginning in 2016). Prior to vesting, holders of PSU's do not have voting rights and are not entitled to receive dividends or dividend equivalents. Dividend equivalents are generally credited to holders of PSU's at the same rate as dividends are paid on our common stock (if and when such dividends are paid), but are only paid for PSU's that vest and become shares of our common stock. PSU's may not be sold, assigned, transferred, pledged or otherwise encumbered until they vest.

For the six months ended June 30, 2017, the Compensation Committee approved share-based payment awards with a total grant date fair value of $30.8 million, as follows:

• 369,897 PSU's with a grant date fair value of $14.6 million and a single vesting opportunity after a three-year service period. These PSU's provide the recipient with an opportunity to vest in incremental PSU's of up to 100% of the initial units awarded subject to the achievement of certain ROIC targets, for a total maximum vesting opportunity of 200% of the initial award. The maximum number of shares of common stock that may be payable with respect to these awards is 739,794.

• 401,997 RSU's with a grant date fair value of $16.2 million and annual vesting opportunities over a three-year service period.

Summary of Outstanding Share-Based Payment Awards—For the six months ended June 30, 2017, changes to the number of outstanding RSU’s, PSU’s, and restricted shares were as follows (shares in thousands):

	Restricted Shares, RSU's and PSU's		Weighted Average Grant Date Fair Value
Outstanding at January 1, 2017	2,235		$	36.40
Granted	772		$	39.87
Vested	(754	)	$	39.07
Canceled	(183	)	$	38.88
Outstanding at June 30, 2017	2,070		$	36.50

As of June 30, 2017, 2.3 million shares were available for future awards issued pursuant to the Restricted Stock Unit Plan. The aggregate fair value of RSU’s and PSU's that vested during the six months ended June 30, 2017 and 2016 was $35.9 million and $13.8 million, respectively, based on the closing stock price on the dates the shares vested.

Stock Options—Stock options issued pursuant to the 1997 Stock Option Plan are exercisable into authorized, but unissued shares of our common stock. Stock options vest evenly over four years and expire ten years after the date of grant. As of June 30, 2017, 104,100 shares of our common stock were available for the issuance of stock options under the Stock Option Plan. As of June 30, 2017, 50,000 stock options were outstanding and exercisable with a weighted average exercise price of $22.11 per share, a weighted average remaining contractual term of 2.6years, and an aggregate intrinsic value of $1.6 million. No stock options were exercised or granted during the six months ended June 30, 2017 and 2016.

33

Directors Stock Plan—Common stock is issued quarterly under the Sotheby’s Stock Compensation Plan for Non-Employee Directors (as amended and restated, the “Directors Stock Plan”). Directors may elect to receive this compensation in the form of deferred stock units, which are credited in an amount that is equal to the number of shares of common stock the director otherwise would have received. The number of shares of common stock awarded is calculated using the closing price of the common stock on the New York Stock Exchange on the business day immediately prior to the quarterly grant date. Deferred stock units are held until a director’s termination of service, at which time the units are settled on a one-for one basis in shares of our common stock on the first day of the calendar month following the date of termination. For the three and six months ended June 30, 2017 and 2016, we recognized $0.3 million and $0.5 million, respectively, within General and Administrative Expenses in our Condensed Consolidated Income Statements related to common stock shares awarded under the Directors Stock Plan. As of June 30, 2017,158,917deferred stock units were outstanding under the Directors Stock Plan and 125,552units were available for future issuance.

18. Earnings Per Share

Basic earnings per share—Basic earnings per share attributable to Sotheby's common shareholders is computed under the two-class method using the weighted average number of common shares outstanding during the period. The two-class method requires that the amount of net income attributable to participating securities be deducted from consolidated net income in the computation of basic earnings per share. In periods with a net loss, the net loss attributable to participating securities is not deducted from consolidated net loss in the computation of basic earnings per share as the impact would be anti-dilutive. Our participating securities include unvested restricted stock units and unvested restricted shares held by employees, both of which have non-forfeitable rights to dividends (see Note 17).

Diluted earnings per share—Diluted earnings per share attributable to Sotheby's common shareholders is computed in a similar manner to basic earnings per share under the two-class method, using the weighted average number of common shares outstanding during the period and, if dilutive, the weighted average number of potential common shares outstanding during the period. Our potential common shares include unvested performance share units held by employees, incremental common shares issuable upon the exercise of employee stock options, and deferred stock units held by members of our Board of Directors (see Note 17).

For the three and six months ended June 30, 2017 and 2016, approximately 1 million potential common shares related to share-based payment awards were excluded from the computation of diluted earnings per share because the financial performance or stock price targets inherent in such awards were not achieved as of the respective balance sheet dates.

34

The table below summarizes the computation of basic and diluted earnings per share for the three and six months ended June 30, 2017 and 2016 (in thousands, except per share amounts):

	Three Months Ended June 30,				Six Months Ended June 30,
	2017		2016		2017		2016

Denominator:
Weighted average common shares outstanding	52,716		57,104		52,866		60,063
Weighted average effect of dilutive potential common shares:
Performance share units	151		458		293		454
Deferred stock units	159		137		157		153
Stock options	28		13		26		12
Weighted average dilutive potential common shares outstanding	338		608		476		619
Weighted average diluted shares outstanding	53,054		57,712		53,342		60,682
Diluted earnings per share - Sotheby’s common shareholders	$	1.43	$	1.52	$	1.21	$	1.03

The decrease in weighted average common shares outstanding between the current and prior year reporting periods is due to common stock repurchases made throughout 2016 and in the second quarter of 2017. See Note 12 for additional information on our share repurchase program.

19. Acquisition of Art Agency, Partners

On January 11, 2016, we acquired Art Agency, Partners, a firm that provides a range of art-related services, in exchange for initial cash consideration of $50 million and future earn-out payments of up to $35 million, as discussed in more detail below. The purpose of this acquisition is to grow auction and private sale revenues by enhancing our relationships with art collectors and by improving our position in the fine art market, particularly in Impressionist, Modern and Contemporary Art. Also, as a result of this acquisition, we have added a new revenue stream by integrating AAP's existing art advisory business, providing a new avenue for growth. The purchase agreement governing the acquisition of AAP includes non-competition and non-solicitation covenants that continue in effect until January 2021. In connection with this acquisition, each of the former principals of AAP also entered into a five-year employment agreement that extends through January 2021. Each employment agreement also includes non-competition and non-solicitation covenants that continue in effect for 12 months following the end of employment.

As indicated above, in connection with the acquisition of AAP, we agreed to make future earn-out payments to the former principals of AAP not to exceed $35 million in the aggregate, contingent on the achievement of a level of cumulative financial performance within the Impressionist, Modern and Contemporary Art collecting categories, as well as from AAP's art advisory business. Progress against the cumulative financial target (the "Target") was to be measured at the end of each calendar year during the four-year performance period following the acquisition, after adjusting the Target to reflect the annual growth or contraction of the auction market for Impressionist, Modern and Contemporary Art, when compared to the year ended December 31, 2015. Amounts owed pursuant to the earn-out arrangement are considered to be compensation expense for accounting purposes and are classified within Salaries and Related Costs in our Condensed Consolidated Income Statements.

For the three and six months ended June 30, 2016, we recognized $2.2 million and $4.4 million, respectively, of compensation expense associated with the AAP earn-out arrangement based on our initial estimate of progress against the Target. For the year ended December 31, 2016, we recognized $35 million of compensation expense associated with the AAP earn-out arrangement, reflecting the full achievement of the Target as a result of our improved market share in the Contemporary Art collecting category, as well as an improvement in auction commission margins, during the initial annual period. The $35 million owed under the earn-out arrangement is being paid in four annual increments of $8.75 million in the first quarter of each year beginning in 2017 and through 2020.The portion of the accrued liability due in the first quarter of 2018 ($8.75 million) is recorded within Accrued Salaries and Related Costs on our Condensed Consolidated Balance Sheets, and the remaining liability ($17.5 million) is recorded within Other Long-Term Liabilities. See Note 10.

The table below summarizes the allocation of the total purchase price paid for AAP to the assets acquired and liabilities assumed (in thousands of dollars):

Purchase price:
Initial cash consideration	$	50,000
Working capital adjustment	1,189
Total purchase price	$	51,189
Allocation of purchase price:
Net working capital acquired	$	1,572
Fixed assets and other long-term assets	173
Goodwill (see Note 5)	34,490
Intangible assets - customer relationships (see Note 5)	10,800
Intangible assets - non-compete agreements (see Note 5)	3,060
Deferred tax assets	1,094
Total purchase price	$	51,189

Upon completion of the purchase price allocation in the second quarter of 2016, $28.3 million of the resulting goodwill was allocated to the Agency segment and $6.2 million was allocated to the acquired art advisory business, which is reported within All Other for segment reporting purposes. The goodwill is tax deductible over a period of 15 years.

We incurred $0.8 million of transaction costs in connection with the acquisition of AAP, which were recognized within General and Administrative Expenses in the fourth quarter of 2015 ($0.6 million) and the first quarter of 2016 ($0.2 million).

36

It is impracticable to compute the amount of revenues and earnings contributed to the Agency segment as a result of the acquisition because the related activities have been integrated into the segment. Disclosure of pro-forma revenues and earnings attributable to the acquisition is also excluded because it is impracticable to determine since AAP was a closely-held private entity and its historical financial records are not available in U.S. GAAP.

20. Related Party Transactions

From time-to-time, in the ordinary course of business, related parties such as members of the Board of Directors and management, buy and sell property at our auctions or through private sales brokered by Sotheby's. For the three and six months ended June 30, 2017, we recognized Agency Commissions and Fees of $1 million and $4.6 million, respectively, related to property sold or purchased by related parties. For the three and six months ended June 30, 2016, such amounts totaled $0.1 million and $0.7 million, respectively. As of June 30, 2017, no amounts were owed to related party consignors. As of June 30, 2016, amounts owed to related party consignors totaled $10.6 million.

21. Recent Accounting Standards Not Yet Adopted

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which introduces a new five-step framework for revenue recognition. The core principal of the standard is that entities should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenue and cash flows arising from an entity's contracts with customers. ASU 2014-09 can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. On August 12, 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers - Deferral of Effective Date, which defers the effective date of ASU 2014-09 to January 1, 2018 with early adoption beginning January 1, 2017. We have identified all material contract types and are in the process of evaluating the impact of adopting ASU 2014-09. We expect to quantify and disclose the expected impact, if any, of adopting ASU 2014-09, in our Form 10-Q for the period ended September 30, 2017. Based on our progress to date, we do not expect the adoption of ASU 2014-09 to have a material impact on the timing of our revenue recognition. However, based on our preliminary conclusions, we anticipate a change in the classification of certain ancillary revenue streams currently recorded on a net basis in our income statement.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments, including requirements to measure most equity investments at fair value with changes in fair value recognized in net income, to perform a qualitative assessment of equity investments without readily determinable fair values, and to separately present financial assets and liabilities by measurement category and by type of financial asset on the balance sheet or in the accompanying notes to the financial statements. ASU 2016-01 will be effective for us beginning on January 1, 2018, and will be applied by means of a cumulative effect adjustment to the balance sheet, except for effects related to equity securities without readily determinable values, which will be applied prospectively. We are currently assessing the potential impact of adopting ASU 2016-01 on our financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases, which requires long-term lease arrangements to be recognized as assets and liabilities on the balance sheet of the lessee. Under ASU 2016-02, a right-of-use asset and lease obligation will be recorded for all long-term leases, whether operating or financing, while the income statement will reflect lease expense for operating leases and interest expense for financing leases. The amendments also require certain new quantitative and qualitative disclosures regarding leasing arrangements. ASU 2016-02 will be effective for us beginning on January 1, 2019. Lessees must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early adoption is permitted. We are currently assessing the potential impact of adopting ASU 2016-02 on our financial statements.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which amends previously issued guidance regarding the impairment of financial instruments by creating an impairment model that is based on expected losses rather than incurred losses. ASU 2016-13 is effective for us beginning on January 1, 2020. Early adoption is permitted. We are currently assessing the potential impact of adopting ASU 2016-13 on our financial statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, which updates guidance as to how certain cash receipts and cash payments should be presented and classified within the statement of cash flows. ASU 2016-15 is intended to reduce the existing diversity in practice and is effective for us beginning on January 1, 2018. Early adoption is permitted. We are currently assessing the potential impact of adopting ASU 2016-15 on our financial statements.

37

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows, which amends ASC 230 to add or clarify guidance on the classification and presentation of restricted cash and restricted cash equivalents in the statement of cash flows. ASU 2016-18 is effective for us beginning on January 1, 2018. Early adoption is permitted. We are currently assessing the potential impact of adopting ASU 2016-18 on our financial statements.

In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business, which amends the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. ASU 2017-01 is effective for us beginning on January 1, 2018 and must be applied prospectively on or after the effective date. We do not expect the adoption of ASU 2017-01 to have a material impact on our financial statements.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit's carrying amount over its fair value. ASU 2017-04 is effective for us beginning on January 1, 2020. Early adoption is permitted. We do not expect the adoption of ASU 2017-04 to have a material impact on our financial statements.

In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which requires entities to disaggregate the current service cost component from the other components of net pension cost (the "other components") to be included in compensation costs in the income statement and present the other components elsewhere in the income statement and outside of income from operations, if that subtotal is presented. In addition, ASU 2017-07 requires entities to disclose the income statement lines that contain the other components if they are not presented on appropriately described separate lines. ASU 2017-07 is effective for us beginning on January 1, 2018. The adoption of ASU 2017-07 will result in the recording of the expected return on plan assets and the amortization of actuarial losses related to the U.K. Pension Plan outside of operating income. Currently, these components of net pension cost (credit) are recorded within Salaries and Related Costs. See Note 6.

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation: Scope of Modification Accounting, which amends the scope of modification accounting for share-based payment arrangements. ASU 2017-09 provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718, Compensation-Stock Compensation. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. We will apply ASU 2017-09 prospectively to any share-based payment awards modified on or after its January 1, 2018 effective date.

ITEM 2:     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF

OPERATIONS

Management's Discussion and Analysis of Financial Condition and Results of Operations (or "MD&A") should be read in conjunction with Note 3 ("Segment Reporting") of Notes to Condensed Consolidated Financial Statements.

Sotheby's Business

Sotheby's is a global art and luxury business, offering its clients opportunities to connect with and transact in the world's most extraordinary objects. Auctioneers since 1744, today we offer a variety of innovative art-related services, including the brokerage of private art sales, the brokerage of private jewelry sales through our Sotheby's Diamonds brand, exclusive private selling exhibitions at our S|2 galleries, art-related financing, and art advisory services, as well as retail wine locations in New York and Hong Kong.

Our operations are organized under two segments: the Agency segment and the Finance segment, which does business as and is referred to in this report as Sotheby’s Financial Services (“SFS”). The Agency segment earns commissions by matching buyers and sellers of authenticated fine art, decorative art, jewelry, wine and collectibles (collectively, "art" or "works of art" or "artwork" or "property") through the auction or private sale process. To a much lesser extent, Agency segment activities also include the sale of artworks that are principally acquired as a consequence of the auction process and RM Sotheby's, an equity investee that operates as an auction house for investment-quality automobiles. SFS earns interest income through art-related financing activities by making loans that are secured by works of art. Art Agency, Partners (“AAP”), through which we offer art advisory services, provides art collectors with strategic guidance on collection identity and development, acquisitions, and short and long-term planning, and provides advice to artists and artists' estates. Our advisory services are classified within All Other for segment reporting purposes, along with our retail wine business and brand licensing activities.

The global art market is influenced over time by the overall strength and stability of the global economy, the financial markets of various countries, geopolitical conditions, and world events, all of which may impact the willingness of potential buyers and sellers to purchase and sell art. Our ability to source high quality and valuable property for consignment is also highly dependent on the meaningful institutional and personal relationships we have with our clients, which sometimes span generations. As these relationships develop over time, we provide our clients with strategic guidance on collection identity, development and acquisition, and then help them navigate the financial, logistical and personal considerations involved with deciding to sell their valued artworks. A client's decision to sell their art may be part of their long-term financial planning process or could occur suddenly as a result of an unexpected change in circumstances. As a result, it is difficult to predict with any certainty the supply of high quality and valuable property available for consignment in advance of peak selling seasons.

Competition in the global art market is intense. Artworks are sold primarily through the major auction houses, numerous art dealers, smaller auction houses, and also directly between private collectors. In recent years, a growing number of art dealers and private collectors now buy and sell artworks at art fairs such as the The European Fine Art Fair (TEFAF), Art Basel, and the Frieze art fairs. A fundamental challenge facing any auctioneer or art dealer is the sourcing of high quality and valuable property for sale either as agent or as principal. Our primary competitor in the global art market is Christie's, a privately owned auction house. To a lesser extent, we also face competition from a variety of art dealers across all collecting categories, as well as smaller auction houses such as Bonhams and Phillips and certain regional auction houses. In the Chinese art market, we compete with Beijing Poly International Auction Co. Ltd., China Guardian Auctions Co. Ltd., and Beijing Council International Auction Co. Ltd.

In response to the competitive environment, we may offer consignors a variety of financial incentives such as auction commission sharing arrangements and auction guarantees as a means to secure high-value consignments. Although these incentives may lead to a higher level of auction consignments, they adversely impact auction commission margins, and auction guarantees introduce the possibility of incurring a loss on the transaction and reduced liquidity if the underlying property fails to sell at the minimum guaranteed price. To mitigate the risk of a decline in auction commission margins, from time-to-time, we adjust our commission rate structures. In addition, we may reduce our financial exposure under auction guarantees through contractual risk and reward sharing arrangements such as irrevocable bids under which a counterparty commits to bid a predetermined price on the guaranteed property. However, we could be exposed to losses in the event any of our counterparties do not perform according to the terms of these contractual arrangements.

39

As noted above, we are a service business in which the ability of our employees to source high-value works of art and develop and maintain relationships with potential sellers and buyers of art is essential to our success. Our business is highly dependent upon attracting and retaining qualified personnel and employee compensation is our most substantial operating expense. We also incur significant costs to promote and conduct our auctions, as well as general and administrative expenses to support our global operations. While a large portion of our expenses are fixed, certain categories of expense are variable. For example, sale marketing costs are dependent upon the volume of auction activity and certain elements of employee compensation are a function of our financial performance.

Seasonality

The global art auction market has two principal selling seasons, which generally occur in the second and fourth quarters of the year. In the aggregate, second and fourth quarter Net Auction Sales¹ represented 82% and 78% of our total annual Net Auction Sales in 2016 and 2015, respectively, with auction commission revenues comprising approximately 75% of our total revenues in each of those years. Accordingly, our financial results are seasonal, with peak revenues and operating income generally occurring in the second and fourth quarters. Consequently, first and third quarter results have historically reflected lower revenues when compared to the second and fourth quarters and, typically, a net loss due to the fixed nature of many of our operating expenses.

In quarterly reporting periods, the comparison of our results between reporting periods can be significantly influenced by a number of factors, such as changes in the timing of when certain auctions occur, the level of non-recurring single-owner auction sale events, the level and timing of individually negotiated private sale transactions, and changes in certain accounting estimates that rely upon forecasted results such as variable incentive and share-based compensation expense and our estimated annual effective income tax rate. Accordingly, when evaluating our performance, we believe that investors should also consider results for rolling six and twelve month periods, which better reflect the business cycle of the global art auction market.

Business and Industry Trends

Following a period of expansion that began in late-2009 and lasted until the fourth quarter of 2015, the global art market entered a period of lower sales, particularly in the Impressionist, Modern and Contemporary Art collecting categories. However, even during this period of lower sales, collectors have continued to purchase top quality works of art for strong prices. We have also recently seen encouraging sell-through rates at our auctions with a greater proportion of sales exceeding their pre-sale low estimates.

During the first six months of 2017, we have experienced a 9% increase in Consolidated Sales¹, when compared to the same period in the prior year, before giving effect to differences in foreign currency exchange rates. During this same period of time, we have also seen an improvement in Auction Commission Margin versus the prior year from 16.1% to 16.7%. However, this improvement has been offset by higher operating expenses, primarily related to incentive compensation, a trend we expect to continue for the balance of the year.

Consolidated Results of Operations for the Three and Six Months Ended June 30, 2017 and 2016

For the six months ended June 30, 2017, we reported net income of $65.6 million ($1.21 per diluted share), representing a $2.5 million (4%) increase when compared to the same period in the prior year when we reported net income of $63.1 million ($1.03 per diluted share). After excluding certain charges in the current and prior year periods, Adjusted Net Income* decreased $2.8 million(4%), from $68.9 million to $66.1 million, as a $21.5 million (6%) increase in Agency commissions and fees was offset by a higher level of indirect expenses and a $3.4 million(11%) decrease in SFS revenues. Despite the 4% decrease in Adjusted Net Income* during the current six month period, Adjusted Diluted EPS* increased 8%, from $1.13 to $1.22, as a result of the significant level of common stock repurchases made over the last 18 months. During this period, we have reduced the number of common stock shares outstanding by 13.1 million, from 65.8 million to 52.7 million.

For the three months ended June 30, 2017, we reported net income of $76.9 million, representing a $12.1 million(14%) decrease when compared to the same period in the prior year, as a higher level of Agency commissions and fees and a lower effective income tax rate are more than offset by a higher level of indirect expenses. Although net income for the three months ended June 30, 2017 decreased by 14%, diluted earnings per share decreased by only 6%, from $1.52 to $1.43, as a result of the lower number of common stock shares outstanding.

Outlook

Based on sales activity to date in 2017, the markets in which we operate continue to show signs of strengthening.  However, given the seasonally low sales levels associated with third quarter auction activity and the traditionally low visibility we have into sales scheduled to occur more than one quarter in the future, it is difficult to forecast revenues for the balance of the year. (See statement on Forward Looking Statements.)

The following tables present a summary of our consolidated results of operations and related statistical metrics for the three and six months ended June 30, 2017 and 2016, as well as a comparison between the current and prior year periods (in thousands of dollars, except per share data):

Separate discussions of Agency segment and SFS results for the three and six months ended June 30, 2017 and 2016, as well as a comparison of our indirect expenses between these periods, are presented in the captioned sections below.

Agency Segment

The Agency segment earns commissions by matching buyers and sellers (also known as consignors) of authenticated works of art through the auction or private sale process. To a much lesser extent, Agency segment activities also include the sale of artworks acquired principally as a consequence of the auction process.

For the six months ended June 30, 2017, Agency segment income before taxes increased $8.4 million (14%), when compared to the same period in the prior year. After excluding certain charges in the current and prior year periods, Adjusted Agency Segment Income Before Taxes* increased $1.2 million (2%). The comparison between the current and prior six month periods is significantly influenced by changes in foreign currency exchange rates, which reduced Adjusted Agency Segment Income Before Taxes* by $7.2 million. Excluding the impact of changes in foreign currency exchange rates, Adjusted Agency Segment Income Before Taxes* increased $8.4 million (12%) principally due to a higher level of auction and private sale commissions, better results from our portfolio of auction guarantees, and a lower level of losses from inventory activities. However, the improvement in these areas is partially offset by a higher level of indirect expenses.

For the three months ended June 30, 2017, Agency segment income before taxes decreased $13.5 million(12%), when compared to the same period in the prior year. The comparison between the current and prior quarterly periods is significantly influenced by changes in foreign currency exchange rates, which reduced Agency segment income before taxes by $3 million. Excluding the impact of changes in foreign currency exchange rates, Agency segment income before taxes decreased $10.5 million (9%) as a higher level of Agency commissions and fees, due in large part to better results from our portfolio of auction guarantees, is more than offset by a higher level of indirect expenses.

Auction Commission Revenue—In our role as auctioneer, we accept property on consignment and match sellers to buyers through the auction process. As compensation for our auction services, we earn a commission from both the buyer ("buyer’s premium") and, to a lesser extent, the seller ("seller’s commission") (collectively, "auction commission revenue"), both of which are calculated as a percentage of Net Auction Sales. Auction commission revenues are recorded net of commissions owed to third parties, which are principally the result of situations when the buyer's premium is shared with a consignor or with the counterparty in an auction guarantee risk and reward sharing arrangement. Additionally, in certain situations, auction commissions are shared with third parties who introduce us to consignors who sell property at auction or otherwise facilitate the sale of property at auction.

For the six months ended June 30, 2017, auction commission revenue increased $4.5 million (1%), when compared to the same period in the prior year. The comparison between the current and prior six month periods is significantly influenced by changes in foreign currency exchange rates, which reduced auction commission revenue by $15.2 million in 2017. Excluding the impact of changes in foreign currency exchange rates, auction commission revenue increased by $19.7 million (6%) due to a 3% increase in Net Auction Sales, after excluding the impact of changes in foreign currency exchange rates, and an increase in Auction Commission Margin from 16.1% to 16.7%.

For the three months ended June 30, 2017, auction commission revenue decreased $5.1 million (2%), when compared to the same period in the prior year. The comparison between the current and prior quarterly periods is significantly influenced by changes in foreign currency exchange rates, which reduced auction commission revenue by $7.2 million in 2017. Excluding the impact of changes in foreign currency exchange rates, auction commission revenues increased by $2.2 million (1%) primarily due to a 1% increase in Net Auction Sales, after excluding the impact of changes in foreign currency exchange rates.

For the three and six months ended June 30, 2017, Net Auction Sales decreased $24.2 million(2%) and $40.5 million(2%), respectively, when compared to the same periods in the prior year. The comparison between the current and prior year periods is significantly influenced by changes in foreign currency exchange rates, which reduced Net Auction Sales by $45.2 million and $97.1 million, respectively, for the three and six months ended June 30, 2017. Excluding the impact of changes in foreign currency exchange rates, Net Auction Sales increased $21 million (1%) and $56.6 million (3%), respectively, for the three and six months ended June 30, 2017. These increases are due to a higher level of Impressionist, Modern, and Contemporary Art sales, which included the sale of Basquiat's Untitled, 1982 for a hammer price of $98 million, exceeding the previous record for sales of this artist's works at auction. These increases are partially offset by lower sales of Asian Art and Jewelry as results for the second quarter of 2016 include the sale of a number of high-value objects and non-recurring single-owner events in these collecting categories. The comparison of year-to-date Net Auction Sales to the prior year is also negatively influenced by lower results from our series of Old Master and British Paintings and Drawings sales, which, in the first quarter of 2016, included a Gentileschi masterpiece ($27 million) and property from the single-owner Taubman Collection ($19.7 million).

Auction Commission Margin—Auction Commission Margin represents total auction commission revenues as a percentage of Net Auction Sales. Typically, Auction Commission Margin is higher for lower value works of art or collections, while higher valued property earns a lower Auction Commission Margin. Accordingly, Auction Commission Margin may be impacted by the mix of property sold in a period. Auction Commission Margin may also be adversely impacted by arrangements whereby we share our buyer's premium with a consignor in order to secure a high-value consignment, as well as by our use of auction guarantees. For example, when issuing an auction guarantee, we may enter into a risk and reward sharing arrangement with a counterparty whereby our financial exposure under the auction guarantee is reduced in exchange for sharing our buyer's premium. Also, in situations when guaranteed property sells for less than the guaranteed price, our buyer's premium from that sale is used to reduce the loss on the transaction. See Note 16 of Notes to Condensed Consolidated Financial Statements for information related to our use of auction guarantees.

On November 13, 2016, we implemented a new buyer's premium rate structure. The new rate structure is 25% on the first $250,000 of hammer (sale) price; 20% on the portion of hammer (sale) price above $250,000 up to and including $3 million; and 12.5% on any remaining amount above $3 million. The hammer (sale) price thresholds in other currencies have been adjusted in a commensurate manner. The previous buyer’s premium rate structure, which had been in effect since February 1, 2015, was 25% on the first $200,000 of hammer (sale) price; 20% on the portion of hammer (sale) price above $200,000 up to and including $3 million; and 12% on the remaining amount above $3 million.

For the six months ended June 30, 2017, Auction Commission Margin increased from 16.1% to 16.7% principally due to improved discipline on consignment terms and the change in the buyer's premium rate structure enacted in the fourth quarter of 2016. The comparison of Auction Commission Margin to the prior year is also influenced by sales of property from the Taubman Collection in the first quarter of 2016. The Taubman Collection was subject to an auction guarantee and although it totaled $22.5 million of Net Auction Sales in the first quarter of 2016, overall sale results fell short of the guaranteed amount, and we did not recognize any net auction commission revenue from the consignment.

Private Sale Commission Revenues—Private sale commission revenues are earned through the direct brokering of purchases and sales of art. Private sales are initiated either by a client wishing to sell property with us acting as their exclusive agent in the transaction, or by a prospective buyer who is interested in purchasing a certain work of art privately. Because private sales are individually negotiated, non-recurring transactions, the volume and value of transactions completed can vary from period to period, with associated variability in revenues.

For the three and six months ended June 30, 2017, private sale commissions increased $0.4 million (3%) and $5.3 million (24%), respectively, due to an increase in high-value transactional volume during the current year period.

Other Agency Commissions and Fees (Net)—Other agency commissions and fees (net) includes: (i) our share of overage or shortfall related to guaranteed property offered or sold at auction; (ii) commissions and other fees earned on sales of art brokered by third parties; (iii) fees charged to consignors for property withdrawn prior to auction, (iv) fees charged for catalogue production and property management; (v) catalogue subscription revenues; and (vi) advertising revenues.

For the three and six months ended June 30, 2017, the improvement in other agency commissions and fees (net) is principally due to better results from our portfolio of auction guarantees.

Inventory Sales and Cost of Inventory Sales—Agency segment inventory sales include amounts earned from the sale of (i) artworks that have been obtained as a result of the failure of guaranteed property to sell at auction, (ii) artworks that have been purchased opportunistically, including property acquired for sale at auction, and (iii) other objects obtained incidental to the auction process (e.g., as a result of buyer default). Agency segment cost of inventory sales includes (i) the net book value of inventory sold, (ii) commissions and fees owed to third parties who help facilitate the sale of inventory, and (iii) writedowns associated with our periodic assessment of inventory valuation.

The tables below present a summary of Agency segment inventory activities for the three and six months ended June 30, 2017 and 2016, as well as a comparison between the current and prior year periods (in thousands of dollars):

The lower loss attributable to our Agency segment inventory activities for the six months ended June 30, 2017 is principally due to a $3.3 million gain on the sale of a painting that was purchased opportunistically and sold at auction in the first quarter of 2017. However, this gain was more than offset by losses associated with the sale or writedown of other inventory items during the current year period.

Sotheby's Financial Services

SFS makes term loans secured by artworks that are not presently intended for sale, allowing us to establish or enhance mutually beneficial relationships with art collectors. To a much lesser extent, SFS also makes consignor advances secured by artworks that are contractually committed, in the near term, to be offered for sale through our Agency segment. See Note 4 of Notes to Condensed Consolidated Financial Statements for additional information about the SFS loan portfolio.

The lending activities of SFS are predominantly funded with borrowings drawn from a dedicated revolving credit facility (the "SFS Credit Facility"). To a lesser extent, cash balances are also used to fund a portion of the SFS loan portfolio, as appropriate. See Note 7 of Notes to Condensed Consolidated Financial Statements for information related to the SFS Credit Facility.

For the three and six months ended June 30, 2017, SFS income before taxes decreased by $1.8 million(17%) and $4.7 million(23%), respectively, when compared to the prior year periods. These decreases are primarily due to a lower level of collateral release and facility fees earned from clients, as well as an increase in credit facility borrowing costs due to a higher level of client loans outstanding. These factors are partially offset by $1.4 million in default interest collected on an overdue client loan in the second quarter of 2017, as well as a higher level of client paid interest income in the second quarter of 2017 due to the higher level of client loans outstanding.

Legend:
*	Represents a variance in excess of 100%.
(a)	Represents interest earned from the Agency segment for secured loans issued with an interest rate below the SFS target rate. Such loans are issued by SFS as an accommodation to the Agency segment in order to secure a consignment or enhance a client relationship. For the three and six months ended June 30, 2017 and 2016, SFS earned client paid interest of $1.1 million resulting from retroactive interest rate increases triggered during those periods. For the three and six months ended June 30, 2016, SFS earned client paid interest of $0.9 million and $3.3 million, respectively, of such retroactive interest. SFS was compensated for these amounts by the Agency segment through credits recorded to intersegment revenues in prior periods. These intersegment revenue credits were reversed in the applicable quarterly reporting periods in 2017 and 2016 upon receipt of the client paid interest.
(b)	Represents fees earned from the Agency segment for secured loans where the facility fee owed by the borrower is either reduced or waived as an accommodation to the Agency segment in order to secure a consignment or enhance a client relationship.
(c)	Represents fees earned from the Agency segment for SFS term loan collateral sold at auction or privately through the Agency segment. Such fees, which represent a portion of the commission revenue earned by the Agency segment on the sale of the loan collateral, are paid to compensate SFS for generating auction and private sale consignments.
(d)	Includes borrowing costs related to the SFS Credit Facility, including interest expense, commitment fees, and the amortization of amendment and arrangement fees.
(e)	We do not allocate salaries and related costs to our cost of revenue, marketing expense, and general and administrative expense line items, as many employees often perform duties that could be categorized across more than one of these line items.

(k)	Calculated as Credit Facility Borrowings divided by the Loan Portfolio Balance.
(l)	Represents the annualized percentage of total client paid and intersegment finance revenues in relation to the Average Loan Portfolio.
(m)	Represents the annualized cost of Credit Facility Borrowings.
(n)	Represents the return on net income attributable to SFS, excluding allocated corporate overhead costs, over the last twelve months ("LTM") in relation to the Average Equity in Loan Portfolio during that period. For the purposes of this calculation, income taxes are provided using the effective income tax rate of SFS for the last twelve months ended June 30, 2017 and 2016, which is approximately 38%.

Marketing Expenses

Marketing expenses are costs related to the promotion of the Sotheby's brand and include digital and print advertising, client relationship development, Sotheby's lifestyle magazines, and certain sponsorship agreements. For the three and six months ended June 30, 2017, marketing expenses increased $1.5 million (35%) and $2.4 million (26%), respectively, when compared to the prior year periods, largely due to costs incurred to promote the opening of a new office in Dubai and the relocation of our Geneva salesroom, as well as spending related to digital initiatives, including costs incurred to livestream our auctions. Also impacting the comparison to the prior year periods are higher sponsorship and client relationship development costs.

(a) Other compensation expense typically includes the cost of temporary labor and overtime, as well as amortization expense related to certain retention-based, new-hire and other employment arrangements.

For the three and six months ended June 30, 2017, salaries and related costs increased $12.1 million (16%) and $8.2 million (6%), respectively, when compared to the same periods in the prior year. The comparisons to the prior year are significantly influenced by changes in foreign currency exchange rates, which reduced salaries and related costs by $2.7 million and $5.4 million during the respective three and six month periods in 2017. Excluding the impact of changes in foreign currency exchange rates, salaries and related costs increased $14.8 million (20%) and $13.6 million (9%), respectively, for the three and six months ended June 30, 2017. See below for a detailed discussion of the significant factors impacting the comparison of the various elements of salaries and related costs between the current and prior year periods.

54

Full-Time Salaries—For the three and six months ended June 30, 2017, full-time salaries increased $2.3 million (6%) and $3.7 million (5%), respectively, when compared to the prior year periods. This increase is principally due to base salary increases and headcount reinvestments, partially offset by the impact of changes in foreign currency exchange rates which reduced full-time salaries by $1.2 million and $2.8 million during the respective three and six month periods in 2017. Excluding the impact of foreign currency exchange rate changes, full-time salaries increased $3.5 million (10%) and $6.5 million (9%), respectively, for the three and six months ended June 30, 2017.

Incentive Compensation—Incentive compensation consists of the accrual for annual cash incentive bonuses, as well as cash payments awarded to employees for brokering certain eligible private sale and other transactions. Payments made under our annual cash incentive bonus plan are aligned with performance against our annual financial plan. For the six months ended June 30, 2017, incentive compensation expense increased $7.4 million (40%), reflecting improved performance against plan targets relative to the prior year.

Share-Based Payment Expense—Share-based payment expense relates to the amortization of equity compensation awards such as performance share units, market-based share units, restricted stock units, and restricted shares. The amount of compensation expense recognized for share-based payments is based, in part, on our estimate of the number of units or shares ultimately expected to vest as a result of employee service. In addition, performance share units vest only if we achieve established profitability targets (for awards granted prior to 2016) or certain ROIC targets (for awards granted beginning in 2016). The amount of compensation expense recognized for such performance-based awards is dependent upon our quarterly assessment of the likelihood of achieving these future profitability or ROIC targets. If our assessment indicates that a greater number of performance share units will vest than previously anticipated, we would record a life-to-date adjustment to increase compensation expense. Conversely, if our assessment indicates that a lower number of performance share units will vest than previously anticipated, we would record a life-to-date adjustment to decrease compensation expense. See Note 17 of Notes to Condensed Consolidated Financial Statements for more detailed information related to our share-based compensation programs.

For the three and six months ended June 30, 2017, share-based payment expense increased $3.7 million and $3.9 million (48%), respectively, when compared to the same periods in the prior year. The comparisons to the prior year reflect an increase in our estimate of the number of performance share units ultimately expected to vest relative to the prior year.

Employee Benefits and Payroll Taxes—Employee benefits include the cost of our retirement plans and health and welfare programs, as well as certain employee severance costs. Our material retirement plans include defined contribution pension plans for our employees in the U.S. and the U.K., as well as a deferred compensation plan for certain U.S. employees (the "DCP") and the U.K. Pension Plan, a defined benefit pension plan.

Generally, the amount of employee benefit costs recognized in a period is dependent upon headcount and overall compensation levels, as well as our financial performance. Additionally, the level of expense related to the U.K. Pension Plan is significantly influenced by service costs, interest rates, investment performance in the debt and equity markets, and actuarial assumptions. Also, the amount of expense recorded in a period for the DCP is dependent upon changes in the fair value of the associated liability resulting from gains and losses in deemed participant investments.

For the three and six months ended June 30, 2017, employee benefits and payroll taxes increased $2.5 million (22%) and $4.5 million (20%), respectively, when compared to the same periods in the prior year. The increase in second quarter employee benefits and payroll taxes is principally due to newly added staff, higher overall compensation levels, and increased employee severance costs, as well as an increase in profit-sharing accruals related to our defined contribution benefit plans. The increase in employee benefits and payroll taxes during the year-to-date period is also, in part, attributable to an increase in payroll taxes associated with a higher value of share-based payment awards vesting during the current year and higher DCP costs as a result of an improvement in the performance of deemed participant investments. On a consolidated basis, the higher level of DCP costs are largely offset by market gains in the trust assets related to the DCP, which are reflected in our Condensed Consolidated Income Statements within non-operating (expense) income.

We expect the net credit associated with the U.K. Pension Plan to decrease by $2.1 million in 2017, from $6.9 million to $4.8 million, primarily due to a lower expected rate of return on plan assets and an increase in the required amortization of prior year actuarial losses. The lower expected rate of return is the result of a change in asset allocation strategy in the first quarter of 2017 which will reduce risk by investing a higher proportion of plan assets in debt securities. The increase in the amortization of prior year actuarial losses is due in large part to a decrease in the discount rate assumption used to value the projected benefit obligation as of December 31, 2016. See Note 6 of Notes to Condensed Consolidated Financial Statements for additional information about the U.K. Pension Plan. (See statement on Forward Looking Statements.)

55

Contractual Severance Agreements—In the first quarter of 2016, we entered into contractual severance agreements with certain former senior employees that provide cash severance benefits and the ability to continue to vest in share-based payment awards after termination of employment. For the six months ended June 30, 2016, salaries and related costs include net charges of $5.7 million associated with these arrangements.

Acquisition Earn-Out Compensation—On January 11, 2016, we acquired AAP, a firm that provides a range of art-related services, in exchange for initial cash consideration of $50 million. In connection with this acquisition, we also agreed to make future earn-out payments to the former principals of AAP not to exceed $35 million in the aggregate, contingent on the achievement of a level of cumulative financial performance within the Impressionist, Modern and Contemporary Art collecting categories, as well as from AAP's art advisory business. Progress against the cumulative financial target (the "Target") was to be measured at the end of each calendar year during the four-year performance period following the acquisition, after adjusting the Target to reflect the annual growth or contraction of the auction market for Impressionist, Modern and Contemporary Art, when compared to the year ended December 31, 2015. Amounts owed pursuant to the earn-out arrangement are compensation expense for accounting purposes and are classified within salaries and related costs in our Condensed Consolidated Income Statements.

For the three and six months ended June 30, 2016, we recognized $2.2 million and $4.4 million, respectively, of compensation expense associated with the AAP earn-out arrangement based on our initial estimate of progress against the Target. For the year ended December 31, 2016, we recognized $35 million of compensation expense associated with the AAP earn-out arrangement, reflecting the full achievement of the Target as a result of our improved market share in the Contemporary Art collecting category, as well as an improvement in auction commission margins, during the initial annual period. The $35 million owed under the earn-out arrangement is being paid in four annual increments of $8.75 million in the first quarter of each year beginning in 2017 and through 2020.

See Note 19 of Notes to Condensed Consolidated Financial Statements for additional information regarding the acquisition of AAP and the related earn-out arrangement.

General and Administrative Expenses

For the three and six months ended June 30, 2017 and 2016, general and administrative expenses consisted of the following (in thousands of dollars):

Total general and administrative expenses	$	82,313	$	76,585	$	5,728		7	%

For the three and six months ended June 30, 2017, general and administrative expenses increased $2.5 million (6%) and $5.7 million (7%), respectively, when compared to the same periods in the prior year. The comparisons to the prior year are influenced by changes in foreign currency exchange rates, which reduced general and administrative expenses by $1.3 million and $2.6 million during the respective three and six month periods in 2017. Excluding changes in foreign currency exchange rates, general and administrative expenses increased $3.8 million (9%) and $8.3 million (11%), respectively, for the three and six months ended June 30, 2017. These increases are due to higher legal fees and business consulting costs, as well as an increase in travel and entertainment and building maintenance expenses.

Income Tax Expense

Our quarterly income tax provision is calculated using an estimated annual effective income tax rate based on actual historical information and forward looking estimates. Our estimated annual effective income tax rate may fluctuate due to changes in forecasted annual pre-tax income, changes in the jurisdictional mix of forecasted pre-tax income, and changes to actual or forecasted permanent book to tax differences (e.g., non-deductible expenses). Furthermore, our effective income tax rate may fluctuate as the result of changes to the valuation allowance for net deferred tax assets, the impact of future tax settlements with federal, state or foreign tax authorities, or the impact of tax law changes. We identify items that are unusual and non-recurring in nature and treat these as discrete events. The tax effect of these discrete events is booked entirely in the quarter in which they occur.

As discussed above, our effective income tax rate may fluctuate due to changes in the jurisdictional mix of forecasted pre-tax income. The impact of such changes could be meaningful in countries with statutory tax rates that are significantly lower than the U.S. statutory tax rate of 35%, if incremental U.S. deferred income taxes are not already being recorded on the earnings of those countries. This is particularly true in countries where we have significant auction operations such as Hong Kong and Switzerland, where the current statutory tax rates are approximately 17% and 23%, respectively.

As of June 30, 2017, we estimate that our annual effective income tax rate, excluding discrete items, will be approximately 29% as compared to our estimate of approximately 26% as of June 30, 2016. The increase in the estimate of our annual effective income tax rate is primarily due to an increase in the amount of incremental U.S. taxes recorded on foreign earnings that are not indefinitely reinvested outside of the U.S.

Our effective income tax rate for the three and six months ended June 30, 2017 was approximately 29% and 27%, respectively, compared to effective income tax rates of approximately 28% and 26% for the three and six months ended June 30, 2016, respectively. The increase in our effective income tax rate for the three months ended June 30, 2017, as compared to the same period in the prior year, is primarily due to the increase in the estimated annual effective income tax rate discussed above and an increase in taxes associated with the earnings of our equity investees. These factors are partially offset by $1.9 million of tax expense recorded in the second quarter of 2016 to reflect a change in our estimated annual effective income tax rate between the first and second quarters of 2016, for which there is no comparable expense in the current period.

The increase in the effective income tax rate for the six months ended June 30, 2017, as compared to the same period in the prior year, is also due to an increase in our estimated annual effective income tax rate, as well as approximately $1 million of net tax expense that was recorded in the current period related to uncertain tax positions, as compared to a tax benefit of approximately $0.2 million recorded in the same period of the prior year. These increases are partially offset by the adoption of Accounting Standards Update (“ASU”) 2016-09, Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting, in the first quarter of 2017, which resulted in the recognition of a $2.6 million discrete tax benefit recorded in the period related to the vesting of share-based payments. (See Note 1 of Notes to Condensed Consolidated Financial Statements for additional information related to the adoption of ASU 2016-09. See Note 15 of Notes to Condensed Consolidated Financial Statements for additional information related to uncertain tax positions.)

Impact of Changes in Foreign Currency Exchange Rates

For the three and six months ended June 30, 2017, changes in foreign currency exchange rates had a net unfavorable impact of $3 million and $6.9 million, respectively, on our operating income, with revenues unfavorably impacted by $8.9 million and $19.8 million, respectively, and expenses favorably impacted by $5.9 million and $12.9 million, respectively. This net unfavorable impact is the result of the strengthening of the U.S. Dollar against the Pound Sterling when compared to the prior year, which adversely impacted the translation of the results from our auctions in London.

NON-GAAP FINANCIAL MEASURES

GAAP refers to generally accepted accounting principles in the United States of America. Included in this Form 10-Q are financial measures presented in accordance with GAAP and also on a non-GAAP basis. The non-GAAP financial measures presented in this Form 10-Q are:

(i)	Adjusted Expenses	(vi)	EBITDA
(ii)	Adjusted Operating Income	(vii)	EBITDA Margin
(iii)	Adjusted Agency Segment Income Before Taxes	(viii)	Adjusted EBITDA
(iv)	Adjusted Net Income	(ix)	Adjusted EBITDA Margin
(v)	Adjusted Diluted Earnings Per Share ("Adjusted Diluted EPS")

We caution users of our financial statements that amounts presented in accordance with our definitions of these non-GAAP financial measures as provided below may not be comparable to similar measures disclosed by other companies because not all companies and analysts calculate such measures in the same manner. Our definitions of the non-GAAP financial measures presented in this Form 10-Q are as follows:

(i)	Adjusted Expenses is defined as total expenses excluding the cost of inventory sales, the cost of finance revenues, (credits) charges related to certain contractual severance agreements (net, recorded within salaries and related costs), earn-out compensation expense related to the acquisition of AAP, and net credits related to our voluntary separation incentive programs.
(ii)	Adjusted Operating Income is defined as operating income excluding (credits) charges related to certain contractual severance agreements (net, recorded within salaries and related costs), earn-out compensation expense related to the acquisition of AAP, and net credits related to our voluntary separation incentive programs.
(iii)	Adjusted Agency Segment Income Before Taxes is defined as Agency segment income before taxes excluding (credits) charges related to certain contractual severance agreements (net, recorded within salaries and related costs), Agency segment earn-out compensation expense related to the acquisition of AAP, net credits in the Agency segment related to our voluntary separation incentive programs, and a charge resulting from the June 2017 amendments to the York Property Mortgage and the associated interest rate collar (recorded within non-operating (expense) income).
(iv)	Adjusted Net Income is defined as net income attributable to Sotheby's, excluding the after-tax impact of (credits) charges related to certain contractual severance agreements (net, recorded within salaries and related costs), earn-out compensation expense related to the acquisition of AAP, net credits related to our voluntary separation incentive programs, and a charge resulting from the June 2017 amendments to the York Property Mortgage and the associated interest rate collar (recorded within non-operating (expense) income).
(v)	Adjusted Diluted EPS is defined as diluted earnings per share excluding the after-tax per share impact of (credits) charges related to certain contractual severance agreements (net, recorded within salaries and related costs), earn-out compensation expense related to the acquisition of AAP, net credits related to our voluntary separation incentive programs (net), and a charge resulting from the June 2017 amendments to the York Property Mortgage and the associated interest rate collar (recorded within non-operating (expense) income).
(vi)	EBITDA is defined as net income attributable to Sotheby's, excluding income tax expense, interest expense, interest income and depreciation and amortization.
(vii)	EBITDA Margin is defined as EBITDA as a percentage of total revenues.
(viii)	Adjusted EBITDA is defined as EBITDA excluding (credits) charges related to certain contractual severance agreements (net, recorded within salaries and related costs), earn-out compensation expense related to the acquisition of AAP, net credits related to our voluntary separation incentive programs, and a charge resulting from the June 2017 amendments to the York Property Mortgage and the associated interest rate collar (recorded within non-operating (expense) income).
(ix)	Adjusted EBITDA Margin is defined as Adjusted EBITDA as a percentage of total revenues.

We use Adjusted Expenses to assess our cost structure when compared to prior periods and on a forward-looking basis, particularly in evaluating performance against our cost control initiatives. Adjusted Expenses provides insight into our ongoing cost structure, absent the interest costs associated with funding the SFS loan portfolio and the cost of inventory sales, which are unpredictable and can vary significantly from one period to the next, and costs associated with unusual items.

58

Adjusted Operating Income, Adjusted Agency Segment Income Before Taxes, Adjusted Net Income, Adjusted Diluted EPS, EBITDA, EBITDA Margin, Adjusted EBITDA, and Adjusted EBITDA Margin are important supplemental measures used in our financial and operational decision making processes, for internal reporting, and as part of our forecasting and budgeting processes, as they provide helpful measures of our core operations. These measures allow us to view operating trends, perform analytical comparisons, and benchmark performance between periods. We also believe that these measures may be used by securities analysts, investors, financial institutions, and other interested parties in their evaluation of our performance.

The presentation of our non-GAAP financial measures for the three and six months ended June 30, 2017 and 2016 has been updated to exclude earn-out compensation expense related to the acquisition of AAP in order to conform with the presentation used in our Annual Report on Form 10-K for the year ended December 31, 2016.

CASH FLOWS FOR THE SIX MONTHS ENDED JUNE 30, 2017 AND 2016

This discussion should be read in conjunction with Sotheby’s Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2017 and 2016. For the six months ended June 30, 2017, total cash and cash equivalents increased $20.4 million to $516.4 million, as compared to a decrease of $373.4 million to $475.3 million for the six months ended June 30, 2016. The significant factors impacting the comparisons between these periods are discussed below.

Net Cash Provided (Used) by Operating Activities—We are predominantly an agency business that collects and remits cash on behalf of our clients. Accordingly, the net amount of cash provided or used in a period by our operating activities is significantly influenced by the timing of auction and private sale settlements. As discussed in Note 4 of Notes to Condensed Consolidated Financial Statements, under our standard auction payment terms, the purchase price is due from the buyer no more than 30 days after the sale date, with the net proceeds due to the consignor 35 days after the sale date. Accordingly, it is not unusual for us to hold significant balances of consignor net sale proceeds at the end of a quarterly reporting period that are disbursed soon thereafter. Additionally, we sometimes provide extended payment terms to an auction or private sale buyer. For auctions, the extent to which extended payment terms are provided can vary considerably from selling season to selling season. In certain instances, and subject to management approval under our internal corporate governance policy, we may pay the net sale proceeds to the consignor before payment is collected from the buyer, with the collection from the buyer sometimes occurring after the current balance sheet date. The amount of net cash provided or used by our operating activities in a reporting period is also a function of our net income or loss, the timing of payments made to vendors, the timing of compensation-related payments, the timing and extent of cash flows related to inventory activities, and the timing of the collection and/or payment of tax-related receivables and payables.

For the six months ended June 30, 2017, net cash provided by operating activities of $56.4 million is principally attributable to our net income for the period ($65.6 million) and net cash inflows from inventory activities ($21 million). These cash inflows are partially offset by net cash outflows of $28.8 million associated with the settlement of auction and private sale transactions during the period, the funding of 2016 incentive compensation ($33.8 million), payments made in respect of the AAP earn-out arrangement ($8.75 million), and income tax payments ($35.7 million). See Note 19 of Notes to Condensed Consolidated Financial Statements for additional information related to the acquisition of AAP.

For the six months ended June 30, 2016, net cash used by operating activities of $47.1 million was principally attributable to net cash outflows of $132 million associated with the settlement of auction and private sale transactions during the period (including approximately $275 million paid to related party consignors). The net cash outflow from operating activities was also impacted by the funding of 2015 incentive compensation payments ($38 million), payments to voluntary separation incentive program participants ($31 million), and income tax payments ($19 million), partially offset by our net income for the period and $34.2 million received upon the sale of an undivided 50% ownership interest in a Fancy Vivid Pink Diamond that was recorded in inventory (see Note 9 of Notes to Condensed Consolidated Financial Statements) in the second quarter of 2016.

61

Net Cash Provided by Investing Activities—For the six months ended June 30, 2017, net cash provided by investing activities of $50.5 million is largely due to a realized net gain of $29.1 million from the settlement of derivative financial instruments designated as net investment hedges and net collections of client loans ($23 million), as well as a $7.7 million decrease in restricted cash, as sale proceeds were paid to consignors in foreign countries where auction houses are legally required to maintain such funds in segregated accounts. These cash inflows are partially offset by capital expenditures of $8.4 million primarily for various office renovations. See Note 8 of Notes to Condensed Consolidated Financial Statements for additional information related to derivative financial instruments.

For the six months ended June 30, 2016, net cash provided by investing activities of $2.9 million was primarily attributable to net collections of client loans ($56.6 million) due in part to proceeds received from loan collateral sales, as well as a $9.8 million decrease in restricted cash as a result of the payment of sale proceeds to consignors in foreign countries where auction houses are legally required to maintain such funds in segregated accounts. These cash inflows were almost entirely offset by the cash used to acquire Art Agency, Partners ($50.7 million, net of cash acquired) in the first quarter of 2016, as well as $10.6 million in capital expenditures incurred for various office renovations and digital technology initiatives. See Note 19 of Notes to Condensed Consolidated Financial Statements for information related to the acquisition of Art Agency, Partners.

Net Cash Used by Financing Activities—For the six months ended June 30, 2017, net cash used by financing activities of $91 million is due to common stock repurchases ($33.9 million), net repayments of borrowings under the SFS Credit Facility ($33.5 million), and the funding of employee tax obligations related to share-based payments ($14.6 million).

For the six months ended June 30, 2016, net cash used by financing activities of $312.9 million was due to Common Stock repurchases of $282.2 million and $18 million in net repayments of borrowings under the SFS Credit Facility.

(a) See Note 7 of Notes to Condensed Consolidated Financial Statements for information related to the York Property Mortgage, the 2022 Senior Notes, and our revolving credit facility. The York Property Mortgage bears interest based on the one-month LIBOR rate (the "LIBOR rate") plus a spread of 2.25%. Due to the variable interest rate associated with the York Property Mortgage, we are party to an interest rate collar, which effectively fixes the LIBOR rate on the York Property Mortgage at an annual rate of no less than 1.917%, but no more than 3.75%. In consideration of the interest rate collar and current LIBOR rates, the table above assumes that the annual interest rate will be at the interest rate collar's floor rate of 4.167% for the remainder of the mortgage term. See Note 8 of Notes to Condensed Consolidated Financial Statements for additional information related to the interest rate collar.

(b) These amounts represent undiscounted future minimum rental commitments under non-cancellable operating leases.

(c) These amounts represent the remaining commitment for future salaries and other cash compensation related to compensation arrangements with certain senior employees, excluding any participation in our incentive compensation and share-based payment programs.

(d) In conjunction with the acquisition of AAP on January 11, 2016, we agreed to make future earn-out payments to the former principals of AAP not to exceed $35 million in the aggregate, contingent on the achievement of a level of cumulative financial performance within the Impressionist, Modern and Contemporary Art collecting categories, as well as from AAP's art advisory business. The cumulative financial performance target associated with this earn-out arrangement was achieved in the fourth quarter of 2016. The remaining $26.3 million owed under the earn-out arrangement will be paid in three annual increments of $8.75 million over the period between February 2018 and January 2020. See Note 19 of Notes to Condensed Consolidated Financial Statements for additional information related to the acquisition of AAP.

(e) This amount represents the minimum guaranteed price associated with auction guarantees outstanding as of June 30, 2017, net of amounts advanced, if any. See Note 16 of Notes to Condensed Consolidated Financial Statements for additional information related to auction guarantees.

(f) Represents unfunded commitments to extend additional credit through SFS. See Note 4 of Notes to Condensed Consolidated Financial Statements for additional information related to the SFS loan portfolio.

63

(g) Excludes the $23 million liability recorded for uncertain tax positions that would be settled by cash payments to the respective taxing authorities, which are classified as long-term liabilities on our Condensed Consolidated Balance Sheets as of June 30, 2017. This liability is excluded from the table above because we are unable to make reliable estimates of the period of settlement with the various taxing authorities. See Note 15 of Notes to Condensed Consolidated Financial Statements.

OFF-BALANCE SHEET ARRANGEMENTS

For information related to off-balance sheet arrangements see: (i) Note 4 of Notes to Condensed Consolidated Financial Statements, which discusses unfunded SFS loan commitments, and (ii) Note 16 of Notes to Condensed Consolidated Financial Statements, which discusses auction guarantees.

UNCERTAIN TAX POSITIONS

For information related to uncertain tax positions, see Note 15 of Notes to Condensed Consolidated Financial Statements.

LIQUIDITY AND CAPITAL RESOURCES

Overview—As of June 30, 2017, we held cash and cash equivalents of $516.4 million, with $66.1 million held in the U.S. and $450.3 million held by our foreign subsidiaries (see “Repatriation of Foreign Earnings” below). After taking into account funds held that are owed to consignors, we estimate available cash balances to be approximately $350 million as of June 30, 2017.

In addition to our available cash balances, we also have access to revolving credit facilities to support the separate capital structures of our Agency segment and SFS. As of June 30, 2017, our revolving credit facilities had a total available borrowing capacity of $160.7 million. (See Note 7 of Notes to Condensed Consolidated Financial Statements for information regarding the terms and conditions of our revolving credit facilities.)

These cash balances and revolving credit facilities are available to support our various capital needs, including the liquidity required to support our recurring business needs, capital required for the pursuit of growth opportunities, and capital to mitigate the risk of a cyclical downturn in the global art market. Importantly, the assessment of our capital needs also takes into consideration the risks associated with our use of auction guarantees and their potential impact on our liquidity. We believe our cash balances and available revolving credit facility borrowings provide an appropriate level of capital to mitigate the risk of a cyclical downturn in the global art market.

Repatriation of Foreign Earnings—In the fourth quarter of 2015, in consideration of the expansion of our common stock repurchase program, as well as the need for cash in the U.S. to fund other corporate strategic initiatives, management assessed its U.S. and foreign cash needs and concluded that approximately $600 million of foreign earnings accumulated through December 31, 2015 would be repatriated to the U.S. in the foreseeable future. As of June 30, 2017, approximately $364 million of these foreign earnings had been repatriated and used, in part, to fund common stock repurchases. We expect that additional repatriations will be made in the future, though the specific timing of any further repatriation of these foreign earnings is currently uncertain and is being evaluated. See statement on Forward Looking Statements.

64

Based on our current projections and planned uses of U.S. and foreign cash, we believe that our cash balances and earnings in the U.S., as well as the amount of unremitted foreign earnings for which a deferred tax liability has been recorded, will be sufficient to satisfy our current cash needs in the U.S. Accordingly, we plan to indefinitely reinvest the prospective earnings of our foreign subsidiaries, except those in the U.K., outside of the U.S. See statement on Forward Looking Statements.

Assessment of Liquidity and Capital Requirements—We have separate capital structures and financial policies for our Agency segment and SFS. The Agency segment generally relies on existing cash balances (including amounts collected on behalf of and owed to consignors), operating cash flows, and revolving credit facility borrowings, if needed, to meet its liquidity and capital requirements. The timing and extent of any revolving credit facility borrowings by the Agency segment is dependent upon a number of factors including, but not limited to, the cyclical nature of the global art market, the seasonality of the art auction market, the timing of auction and private sale settlements, the potential funding of auction guarantees, the pursuit of business opportunities and growth initiatives, and the timing of the repatriation of foreign earnings.

SFS predominantly relies on revolving credit facility borrowings to fund client loans. To a lesser extent, cash balances are also used to fund a portion of the SFS loan portfolio, as appropriate. The timing and extent of revolving credit facility borrowings by SFS is dependent upon a number of factors including, but not limited to, the demand for art-related financing, which can be significantly influenced by overall economic conditions and by the often unpredictable financial requirements of owners of major art collections, the timing of the funding of new client loans, and the timing of the settlement of existing client loans.

Our short-term and long-term operating needs and capital requirements include: (i) the funding of net sales proceeds to consignors when unmatched extended payment terms are granted to auction or private sale buyers (see Note 4 of Notes to Condensed Consolidated Financial Statements); (ii) the potential funding of auction guarantees (see Note 16 of Notes to Condensed Consolidated Financial Statements); (iii) the funding of potential client loans; (iv) the potential repayment of revolving credit facility borrowings and other debt; (v) the funding of capital expenditures; (vi) the funding of other possible business initiatives and/or investments; (vii) the funding of common stock repurchases (see Note 12 of Notes to Condensed Consolidated Financial Statements); and (viii) the funding of the other short-term and long-term commitments summarized in the table of contractual obligations and commitments above. See statement on Forward Looking Statements.

We believe that operating cash flows, existing cash balances, and revolving credit facility borrowings will be adequate to support our anticipated short and long-term commitments, operating needs and capital requirements, as well as provide sufficient capital to mitigate the risk of cyclical downturns in the global art market through the August 22, 2020 expiration of our revolving credit facilities. See statement on Forward Looking Statements.

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We continually evaluate the market risk associated with our financial instruments in the normal course of our business. As of June 30, 2017, our material financial instruments include: (i) cash and cash equivalents; (ii) restricted cash; (iii) notes receivable; (iv) credit facility borrowings; (v) the York Property Mortgage; (vi) various derivative financial instruments, including interest rate swaps, an interest rate collar, and outstanding forward exchange contracts, as discussed in more detail below; and (vii) long-term debt. See Note 4 of Notes to Condensed Consolidated Financial Statements for information related to notes receivable. See Note 7 of Notes to Condensed Consolidated Financial Statements for information related to credit facility borrowings, the York Property Mortgage, and long-term debt. See Note 8 of Notes to Condensed Consolidated Financial Statements for information regarding our derivative financial instruments.

Interest Rate Risk—On July 1, 2015, we entered into a seven-year, $325 million mortgage loan to refinance the previous mortgage on the York Property. The York Property Mortgage bears interest based on the one-month LIBOR rate plus a spread of 2.25% and is being amortized based on a 25-year mortgage-style amortization schedule over its seven-year term. On June 21, 2017, the York Property Mortgage was amended to reduce the minimum net worth that Sotheby's is required to maintain from $425 million to $325 million in order to provide continued flexibility regarding potential future share repurchases. In conjunction with this amendment, on July 3, 2017, we made a partial prepayment of $32 million to reduce the outstanding principal balance of the York Property Mortgage, and agreed to make annual prepayments beginning in July 2018 and continuing through July 2021 that are not to exceed $25 million in the aggregate during that period. The $32 million payment made on July 3, 2017 was funded with $25 million from existing cash balances and $7 million from a restricted cash management account related to the mortgage. Any prepayments made during the period July 2018 to July 2021 will also be funded from the restricted cash management account. See Note 7 of Notes to Condensed Consolidated Financial Statements for information on the restricted cash management account related to the York Property Mortgage.

In connection with the York Property Mortgage, we entered into interest rate protection agreements secured by the York Property, consisting of a two-year interest rate swap (the "Mortgage Swap"), effective as of July 1, 2015, and a five-year interest rate collar (the "Mortgage Collar"), effective as of July 1, 2017. These interest rate protection agreements effectively fix the LIBOR rate on the York Property Mortgage at an annual rate equal to 0.877% for the first two years, and then at an annual rate of no less than 1.917%, but no more than 3.75%, for the remainder of the seven-year term. After taking into account the interest rate protection agreements, the annual interest rate for the first two years of the York Property Mortgage was approximately 3.127% and then will be between a floor of 4.167% and a cap of 6% for the remaining seven-year term.

In conjunction and concurrent with the June 2017 amendment to the York Property Mortgage, the notional amount of the Mortgage Collar was reduced by $57 million to reflect: (i) the $32 million prepayment made on the York Property Mortgage on July 3, 2017 and (ii) potential annual prepayments of $6.25 million each beginning in July 2018 and continuing through July 2021.

As of June 30, 2017, the notional value of the Mortgage Swap was $311 million and the notional value of the Mortgage Collar was $278.3 million. As of June 30, 2017, the Mortgage Swap and the Mortgage Collar each have a notional amount that is no greater than the applicable forecasted principal balance of the York Property Mortgage.

On November 21, 2016, we entered into a two-year interest rate swap agreement (the “SFS Swap”) to eliminate the variability in expected cash outflows associated with the one-month LIBOR indexed interest payments owed on $63 million of SFS Credit Facility borrowings. As of June 30, 2017, the notional value of the SFS Swap was $63 million.

We believe that the interest rate risk associated with our other financial instruments is minimal as a hypothetical 10% increase or decrease in interest rates is immaterial to our cash flow, earnings, and the fair value of our financial instruments.

We are exposed to credit-related risks in the event of nonperformance by the counterparties to the Mortgage Swap, the SFS Swap, and the Mortgage Collar. We do not expect any of these counterparties to fail to meet their obligations, given their high short-term (A1/P1) credit ratings.

Foreign Currency Exchange Rate Risk—We utilize forward contracts to hedge cash flow exposures related to foreign currency exchange rate movements, which primarily arise from short-term foreign currency denominated intercompany balances and, to a much lesser extent, foreign currency denominated client payable balances, as well as foreign currency denominated auction guarantee obligations. Such forward exchange contracts are typically short-term with settlement dates less than six months from their inception. All derivative financial instruments are entered into by our global treasury function, which is responsible for monitoring and managing our exposure to foreign currency exchange rate movements. As of June 30, 2017, the notional value of outstanding forward exchange contracts used to hedge such cash flow exposures was $197.9 million.

67

As of June 30, 2017, our foreign subsidiaries held approximately $427.2 million in foreign currency denominated cash balances. A hypothetical 10% strengthening or weakening of the U.S. dollar relative to all other currencies would result in a decrease or increase in our cash flow of approximately $42.7 million related to such foreign currency balances.

We are exposed to variability in the U.S. Dollar equivalent of the net investments in our foreign subsidiaries and, by extension, the U.S. Dollar equivalent of any foreign earnings repatriated to the U.S. due to potential changes in foreign currency exchange rates. As a result, we regularly enter into foreign currency forward exchange contracts to hedge the net investments in our foreign subsidiaries from which we expect to repatriate earnings to the U.S. As of June 30, 2017, the aggregate notional value of our outstanding net investment hedge contracts was $49.7 million.

We are exposed to credit-related risks in the event of nonperformance by the counterparties to our outstanding forward exchange contracts. We do not expect any of these counterparties to fail to meet their obligations, given their high short-term (A1/P1) credit ratings.

ITEM 4: CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

As of June 30, 2017, the Company has carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Company’s disclosure controls and procedures. Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) were effective as of June 30, 2017.

Changes in Internal Control over Financial Reporting

There was no change in the Company’s internal control over financial reporting that occurred during the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

See Note 12 of Notes to Condensed Consolidated Financial Statements for information regarding common stock repurchases for the six months ended June 30, 2017 and 2016.

68

The timing of further share repurchases and the actual amount purchased will depend on a variety of factors including the market price of our common stock, general market and economic conditions, securities law requirements, and other corporate considerations. Repurchases may continue to be made pursuant to plans intended to comply with Rule 10b5-1 under the Exchange Act, which allows us to purchase our shares during periods when we otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods. The repurchase authorization does not require the purchase of a specific number of shares and is subject to suspension or termination by our Board of Directors at any time.

Reference is made to the Agreement of Partnership (the “Partnership Agreement”) of Acquavella Modern Art, a Nevada general partnership, dated May 29, 1990, between Sotheby’s Nevada, Inc., a Nevada corporation (“Sotheby’s Partner”), and Acquavella Contemporary Art, Inc., a Nevada corporation (“Acquavella Partner”), as amended.

This letter amendment (this “Amendment”) further amends the Partnership Agreement as follows:

1.    Certain Purchases of Partnership Interests.

Each of the Sotheby’s Partner and the Acquavella Partner hereby agree that as of the date of this Amendment, Acquavella’s successor(s) in interest shall no longer have any right pursuant to Section 6.5(c) of the Partnership Agreement or otherwise to require Sotheby’s to purchase the Partnership Interest of Acquavella upon the death of W.A.

In furtherance of the foregoing, each of the Sotheby’s Partner and the Acquavella Partner hereby agree that Section 6.5(c) of the Partnership Agreement is hereby deleted in its entirety and replaced with “(c) Intentionally omitted.”.

Each of the Sotheby’s Partner and the Acquavella Partner hereby agree that any reference in the Partnership Agreement to the “Put Notice” shall no longer have any force or effect.

By prior letters of amendment, the Sotheby’s Partner and the Acquavella Partner have agreed to extend the term of the Partnership Agreement through May 1, 2017.  By this Amendment, the Sotheby’s Partner and the Acquavella Partner are agreeing to extend the term of the Partnership Agreement through May 1, 2022.  Accordingly, each of the

Sotheby’s Partner and the Acquavella Partner hereby agree to amend Section 1.5(iii) of the Partnership Agreement, as heretofore amended, to delete the reference to May 1, 2017 and substitute therefor the date of “May 1, 2022.”

3.    Miscellaneous

Except as amended hereby, the Partnership Agreement shall remain in full force and effect and is hereby ratified and confirmed.

The provisions of Article 10.3 (Applicable Law) shall be deemed to have been included herein.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

Accounting Principles—The unaudited Condensed Consolidated Financial Statements included herein have been prepared by the management of Sotheby’s (or the "Company") in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") and pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted from this report, as is permitted by such rules and regulations. In our opinion, the unaudited Condensed Consolidated Financial Statements reflect all adjustments of a normal recurring nature that are necessary for a fair presentation of the results for the interim periods presented. Interim results are not necessarily indicative of results for a full year (see Note 2). We urge you to read these Condensed Consolidated Financial Statements in conjunction with the information included in our 2016 Form 10-K filed with the SEC on February 27, 2017.

Principles of Consolidation—The unaudited Condensed Consolidated Financial Statements include the accounts of our wholly-owned subsidiaries and Sotheby's (Beijing) Auction Co., Ltd. ("Sotheby's Beijing"), a joint venture in which we have a controlling 80% ownership interest. The net income (loss) attributable to the minority owner of Sotheby's Beijing is reported as "Net Income (Loss) Attributable to Noncontrolling Interest" in our Condensed Consolidated Income Statements and the non-controlling 20% ownership interest is reported as "Noncontrolling Interest" within the Equity section of our Condensed Consolidated Balance Sheets. Intercompany transactions and balances among our subsidiaries are eliminated in consolidation.

Equity investments through which we exercise significant influence over the investee, but do not control, are accounted for using the equity method. Under the equity method, our share of investee earnings or losses is recorded within Equity in Earnings of Investees in our Condensed Consolidated Income Statements. Our interest in the net assets of these equity method investees is recorded within Other Long-Term Assets on our Condensed Consolidated Balance Sheets. Our equity method investees include: (i) Acquavella Modern Art ("AMA"), a partnership through which a collection of fine art is being sold, (ii) RM Sotheby's, an auction house for investment-quality automobiles, and (iii) a partnership formed in the second quarter of 2017 through which artworks are being purchased and sold (see Note 10).

Presentation of Salaries and Related Costs—We do not allocate salaries and related costs to our cost of revenue, marketing expense, and general and administrative expense line items, as many employees often perform duties that could be categorized across more than one of these line items.

Estimates and Assumptions—The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Adoption of Accounting Standards Update ("ASU") 2016-09—In March 2016, the Financial Accounting Standards Board (the "FASB") issued ASU 2016-09, Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies several aspects of the accounting and presentation of share-based payment transactions, including the accounting for the related income tax consequences and certain classifications within the statement of cash flows. We adopted ASU 2016-09 on its effective date of January 1, 2017.

ASU 2016-09 requires that all excess tax benefits and deficiencies resulting from the vesting of share-based payments be recorded in the statement of operations, whereas previous guidance generally permitted such items to be recorded in the equity section of the balance sheet provided that an adequate level of previously recorded excess tax benefits existed. We adopted this aspect of ASU 2016-09 on a prospective basis beginning on January 1, 2017. The adoption of ASU 2016-09 and the vesting of certain share-based payments in the first quarter of 2017 resulted in the recording of a discrete $2.6 million income tax benefit in our Condensed Consolidated Income Statements, which decreased our effective income tax rate for the six months ended June 30, 2017 by approximately 3%. Under previous guidance, this income tax benefit would have been recorded as an increase to Additional Paid-In Capital on our Condensed Consolidated Balance Sheets.

ASU 2016-09 also changed how excess tax benefits resulting from the vesting of share-based payments are presented in the statement of cash flows. ASU 2016-09 requires that such excess tax benefits be classified within Operating Activities along with other income tax cash flows. Under previous guidance, excess tax benefits resulting from the vesting of share-based payments were presented as a cash inflow within Financing Activities and a corresponding cash outflow within Operating Activities. The adoption of ASU 2016-09 in the first quarter of 2017 resulted in the classification of $2.6 million of excess tax benefits within Operating Activities in our Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2017. The retrospective adoption of ASU 2016-09 did not have an effect on our Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2016 because no excess tax benefits were recorded in that period.

The adoption of the other aspects of ASU 2016-09 did not have a material impact on our Condensed Consolidated Financial Statements as of and for the three and six months ended June 30, 2017 and 2016.

Adoption of Other Recently Issued Accounting Standards—In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging: Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships, which clarifies that a change in the counterparty to a derivative instrument that has been designated as a hedging instrument would not, in and of itself, be considered a termination of the derivative instrument, provided that all other hedge accounting criteria continue to be met. The adoption of ASU 2016-05 on its effective date of January 1, 2017 did not have a material effect on our Condensed Consolidated Financial Statements as of and for the three and six months ended June 30, 2017 and 2016.

In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging-Contingent Put and Call Options in Debt Instruments, which aims to reduce the diversity of practice in identifying embedded derivatives in debt instruments. ASU 2016-06 clarifies that the nature of an exercise contingency is not subject to the “clearly and closely” criteria for purposes of assessing whether the call or put option must be separated from the debt instrument and accounted for separately as a derivative. The adoption of ASU 2016-06 on its effective date of January 1, 2017 did not have a material effect on our Condensed Consolidated Financial Statements as of and for the three and six months ended June 30, 2017 and 2016.

Seasonality Of Business [Abstract]

Seasonality of Business

Seasonality of Business

The global art auction market has two principal selling seasons, which generally occur in the second and fourth quarters of the year. In the aggregate, second and fourth quarter Net Auction Sales¹ represented 82% and 78% of our total annual Net Auction Sales for the years ended December 31, 2016 and 2015, respectively, with auction commission revenues comprising approximately 75%of our total revenues in each of those years. Accordingly, our financial results are seasonal, with peak revenues and operating income generally occurring in the second and fourth quarters. Consequently, first and third quarter results have historically reflected lower revenues when compared to the second and fourth quarters and, typically, a net loss due to the fixed nature of many of our operating expenses.

Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

Sotheby's is a global art and luxury business, offering its clients opportunities to connect with and transact in the world's most extraordinary objects. Auctioneers since 1744, today we offer a variety of innovative art-related services, including the brokerage of private art sales, the brokerage of private jewelry sales through our Sotheby's Diamonds brand, exclusive private selling exhibitions at our S|2 galleries, art-related financing, and art advisory services, as well as retail wine locations in New York and Hong Kong. Our operations are organized under two segments—the Agency segment and the Finance segment, which does business as and is referred to in this report as Sotheby's Financial Services (or "SFS"). Thomas S. Smith, Jr, Sotheby's Chief Executive Officer, is our chief operating decision maker. Mr. Smith regularly evaluates financial information about each of our segments in deciding how to allocate resources and assess performance. The performance of each segment is measured based on segment income before taxes, which excludes the unallocated items highlighted in the reconciliation below.

Through our Agency segment, we accept property on consignment, stimulate buyer interest through professional marketing techniques, and match sellers (also known as consignors) to buyers through the auction or private sale process. Prior to offering a work of art for sale, we perform due diligence activities to authenticate and determine the ownership history of the property being sold. To a much lesser extent, Agency segment activities also include the sale of artworks that are principally acquired as a consequence of the auction process, and RM Sotheby's, an equity investee that operates as an auction house for investment-quality automobiles. The Agency segment is an aggregation of the auction, private sale, and other related activities conducted by our operating segments in the Americas, Europe, and Asia, which have similar economic characteristics and are similar in their services, customers, and the manner in which their services are provided.

SFS is an art financing company that operates as a niche lender with the ability to tailor attractive financing packages for clients who wish to obtain immediate access to liquidity from their art assets. SFS deploys a unique combination of art expertise, skill in international law and finance, and access to capital to provide art collectors and dealers with financing secured by their works of art, allowing them to unlock the value in their collections.

Art Agency, Partners (“AAP”), through which we offer art advisory services, provides art collectors with strategic guidance on collection identity and development, acquisitions, and short and long-term planning, and provides advice to artists and artists' estates. AAP was acquired on January 11, 2016 (see Note 19). Our advisory services are classified within All Other for segment reporting purposes, along with our retail wine business, brand licensing activities, the results from certain equity method investments (see Note 10), and sales of the remaining inventory of Noortman Master Paintings, an art dealer that was owned and operated by us from its acquisition in 2006 until its closure in December 2013.

The following table presents our segment information for the three and six months ended June 30, 2017 and 2016 (in thousands of dollars):

Receivables

Accounts and Notes Receivable, Net [Abstract]

Receivables

Receivables

Accounts Receivable (Net)—Through our Agency segment, we accept property on consignment and match sellers, also known as consignors, to buyers through the auction or private sale process. Following an auction or private sale, we invoice the buyer for the purchase price of the property (including our commission, as well as any applicable taxes and royalties), collect payment from the buyer, and remit to the consignor the net sale proceeds after deducting our commissions, expenses and applicable taxes and royalties.

Under our standard auction payment terms, the purchase price is due from the buyer no more than 30 days after the sale date, with the net proceeds due to the consignor 35 days from the sale date. For private sales, payment from the buyer is typically due on the sale date, with the net sale proceeds due to the consignor shortly thereafter. We also sometimes provide extended payment terms to an auction or private sale buyer. For auctions, the extent to which extended payment terms are provided can vary considerably from selling season to selling season. Extended payment terms typically extend the payment due date to a date that is no longer than one year from the sale date. In limited circumstances, the payment due date may be extended to a date that is beyond one year from the sale date. When providing extended payment terms, we attempt to match the timing of cash receipt from the buyer with the timing of our payment to the consignor, but are not always successful in doing so. All extended payment term arrangements are approved by management under our internal corporate governance policy.

In the limited circumstances when the buyer's payment due date is extended to a date that is beyond one year from the sale date, if the consignor does not provide matched payment terms (i.e., we pay the consignor before receiving payment from the buyer), the receivable balance is reclassified from Accounts Receivable to Notes Receivable on our Condensed Consolidated Balance Sheets. As of June 30, 2017, December 31, 2016, and June 30, 2016, Notes Receivable within the Agency segment included $2.6 million, $7.5 million, and $12.2 million, respectively, of such balances that have been reclassified from Accounts Receivable. See discussion of Agency segment Notes Receivable below.

Under the standard terms and conditions of our auction and private sales, we are not obligated to pay the consignor for property that has not been paid for by the buyer. If a buyer defaults on payment, the sale may be cancelled, and the property will be returned to the consignor. Alternatively, the consignor may reoffer the property at one of our future auctions or negotiate a private sale with us acting as their agent. In certain instances, and subject to management approval under our internal corporate governance policy, we may pay the net sale proceeds to the consignor before payment is collected from the buyer and/or we may allow the buyer to take possession of the property before making payment. In situations when the buyer takes possession of the property before making payment, we are liable to the seller for the net sales proceeds whether or not the buyer makes payment. As of June 30, 2017, December 31, 2016, and June 30, 2016, Accounts Receivable (net) included $85.3 million, $90.1 million, and $104.5 million, respectively, related to situations when we paid the consignor all or a portion of the net sales proceeds before payment was collected from the buyer. As of June 30, 2017, December 31, 2016, and June 30, 2016, Accounts Receivable (net) also included $33.4 million, $76.3 million, and $33.9 million, respectively, related to situations when we allowed the buyer to take possession of the property before making payment.

Notes Receivable (Sotheby's Financial Services)—SFS makes term loans secured by artworks that are not presently intended for sale, allowing us to establish or enhance mutually beneficial relationships with art collectors. Term loans may also generate future auction or private sale consignments and/or purchases. In certain situations, term loans are made to refinance receivables generated by the auction and private sale purchases of our clients. Term loans normally have initial maturities of up to two years and typically carry a variable market rate of interest. To a much lesser extent, SFS also makes consignor advances secured by artworks that are contractually committed, in the near term, to be offered for sale through our Agency segment. Consignor advances allow sellers to receive funds upon consignment for an auction or private sale that will occur up to one year in the future and normally have short-term maturities.

The lending activities of SFS are predominantly funded with borrowings drawn from a dedicated revolving credit facility. To a lesser extent, cash balances are also used to fund a portion of the loans made by SFS, as appropriate. See Note 7 for information related to the dedicated revolving credit facility for SFS.

As of June 30, 2017, December 31, 2016, and June 30, 2016, the net Notes Receivable balance of SFS was $651.4 million, $675.1 million, and $629.7 million, respectively. As of June 30, 2017, December 31, 2016, and June 30, 2016, the total net Notes Receivable balance of SFS included $85.6 million, $88.7 million, and $104.4 million, respectively, of term loans issued by SFS to refinance client auction and private sale purchases. For the six months ended June 30, 2017 and 2016, SFS issued $3.8 million and $9.3 million, respectively, of such loans. These loans are accounted for as non-cash transfers between Accounts Receivable (net) and Notes Receivable (net) and are, therefore, not reflected as the funding of Notes Receivable within Investing Activities in our Condensed Consolidated Statements of Cash Flows. Upon repayment, the cash received in settlement of such Notes Receivable is classified within Operating Activities in our Condensed Consolidated Statements of Cash Flows. For the six months ended June 30, 2017 and 2016, such repayments totaled $6.9 million and $13.7 million, respectively.

The repayment of secured loans can be adversely impacted by a decline in the art market in general or in the value of the collateral, which is concentrated within certain collecting categories. In addition, in situations when there are competing claims on the collateral and/or when a borrower becomes subject to bankruptcy or insolvency laws, our ability to realize on our collateral may be limited or delayed.

We aim to mitigate the risk associated with a potential devaluation in our collateral by targeting a 50% loan-to-value ("LTV") ratio (i.e., the principal loan amount divided by the low auction estimate of the collateral). However, loans may also be made with LTV ratios between 51% and 60%, and, in rare circumstances, loans may be made at an initial LTV ratio higher than 60%. The revolving credit facility for SFS permits borrowings of up to 85% of the portion of any loan that does not exceed a 60% LTV ratio.

The LTV ratio of certain loans may increase above the 50% target due to a decrease in the low auction estimates of the collateral. The revaluation of term loan collateral is performed by our specialists on an annual basis or more frequently if there is a material change in the circumstances related to the loan, the value of the collateral, the disposal plans for the collateral, or if an event of default occurs. We believe that the LTV ratio is a critical credit quality indicator for the secured loans made by SFS.

The table below provides the aggregate LTV ratio for the SFS loan portfolio as of June 30, 2017, December 31, 2016, and June 30, 2016 (in thousands of dollars):

We consider a loan to be past due when principal payments are not paid by the contractual maturity date. Typically, a loan becomes past due only for a short period of time during which either the loan is renewed or collateral is sold to satisfy the borrower's obligations. As of June 30, 2017, $108.6 million of the net Notes Receivable balance was past due, of which $41.4 million was more than 90 days past due. The collateral securing these past due loans has a low auction estimate of approximately $232.5 million resulting in an LTV ratio of approximately 47%. We are continuing to accrue interest on all past due loans. In consideration of expected loan renewals, loan payments, and $33.3 million in collateral sales to date related to loans that are more than 90 days past due for which the proceeds have not yet been collected from the buyer, as well as the value of the remaining collateral and our current collateral disposal plans, we believe that the principal and interest amounts owed for these past due loans will be collected.

A non-accrual loan is a loan for which future Finance revenue is not recorded due to our determination that it is probable that future interest on the loan is not collectible. Any cash receipts subsequently received on non-accrual loans are first applied to reduce the recorded principal balance of the loan, with any proceeds in excess of the principal balance then applied to interest owed by the borrower. The recognition of Finance revenue may resume on a non-accrual loan if sufficient additional collateral is provided by the borrower or if we become aware of other circumstances that indicate that it is probable that the borrower will make future interest payments on the loan. As of June 30, 2017, there were no non-accrual loans outstanding. As of December 31, 2016 and June 30, 2016, there was a $0.2 million non-accrual loan outstanding. This loan was written-off in the second quarter of 2017.

A loan is considered to be impaired when we determine that it is probable that a portion of the principal and interest owed by the borrower will not be recovered after taking into account the estimated realizable value of the collateral securing the loan, as well as the ability of the borrower to repay any shortfall between the value of the collateral and the amount of the loan. If a loan is considered to be impaired, Finance revenue is no longer recognized and bad debt expense is recorded for any principal or accrued interest that is deemed uncollectible. As of June 30, 2017, December 31, 2016, and June 30, 2016, there were no impaired loans outstanding.

During the period January 1, 2017 to June 30, 2017, activity related to the Allowance for Credit Losses was as follows (in thousands of dollars):

Allowance for credit losses as of January 1, 2017	$	1,270
Change in loan loss provision	20
Allowance for credit losses as of June 30, 2017	$	1,290

As of June 30, 2017, unfunded commitments to extend additional credit through SFS were approximately $26 million.

Notes Receivable (Agency Segment)—We are obligated under the terms of certain auction guarantees to advance a portion of the guaranteed amount prior to the auction. Such auction guarantee advances are recorded on our Condensed Consolidated Balance Sheets within Notes Receivable (net). As of June 30, 2017 and June 30, 2016, there were no auction guarantee advances outstanding. As of December 31, 2016, there were $1 million of auction guarantee advances outstanding. See Note 16 for additional information related to auction guarantees.

As discussed above, in the limited circumstances when the payment due date for an auction or private sale receivable is extended to a date that is beyond one year from the sale date, if the consignor does not provide matched payment terms, the receivable balance is reclassified from Accounts Receivable (net) to Notes Receivable (net) on our Condensed Consolidated Balance Sheets. As of June 30, 2017 and December 31, 2016, Notes Receivable (net) within the Agency segment included $2.6 million and $7.5 million, respectively, of such amounts reclassified from Accounts Receivable (net), against which we hold approximately $3.1 million of collateral. As of June 30, 2016, Notes Receivable (net) within the Agency segment included $12.2 million of such reclassified amounts, against which we held $6.6 million of collateral. These Notes Receivable are accounted for as non-cash transfers between Accounts Receivable (net) and Notes Receivable (net) and are, therefore, not reflected as the funding of Notes Receivable within Investing Activities in our Condensed Consolidated Statements of Cash Flows. Upon repayment, the cash received in settlement of such Notes Receivable is classified within Operating Activities in our Condensed Consolidated Statements of Cash Flows. For the six months ended June 30, 2017 and 2016, such repayments totaled $5 million and $7.5 million, respectively.

Under certain circumstances, we provide loans to certain art dealers to finance the purchase of works of art. In these situations, we acquire a partial ownership interest or a security interest in the purchased property in addition to providing the loan. Upon the eventual sale of the property acquired, the loan is repaid. As of June 30, 2017, December 31, 2016, and June 30, 2016, such loans totaled $3.8 million, $3.8 million, and $4.1 million, respectively. We are no longer accruing interest with respect to one of these loans with a balance of $2.1 million, but management believes that this balance is collectible.

Notes Receivable (Other)—In the second quarter of 2013, we sold our interest in an equity method investee for $4.3 million. The sale price was funded by an upfront cash payment of $0.8 million and the issuance of a $3.5 million unsecured loan. This loan had a variable market rate of interest, required monthly payments during the loan term, and was initially scheduled to mature in December 2018. As of December 31, 2016 and June 30, 2016, the carrying value of this loan was approximately $2.1 million and $2.3 million, respectively. The entire remaining balance of the loan was repaid in the second quarter of 2017.

Revolving Credit Facilities—We are party to a credit agreement with an international syndicate of lenders, which provides for separate dedicated revolving credit facilities for the Agency segment (the "Agency Credit Facility") and SFS (the "SFS Credit Facility") (the "Credit Agreement"). The maturity date of the Credit Agreement is August 22, 2020.

The Agency Credit Facility and the SFS Credit Facility are asset-based revolving credit facilities which may be used primarily for the working capital and other general corporate needs of each segment, including for the funding of SFS loans. The Credit Agreement allows the proceeds from borrowings under each of the revolving credit facilities to be transferred between the Agency segment and SFS.

The maximum aggregate borrowing capacity of the Credit Agreement, which is subject to a borrowing base, is approximately $1.335 billion, with $300 million committed to the Agency segment and $1.035 billion committed to SFS. The borrowing capacity of the Agency Credit Facility includes a $50 million incremental revolving credit facility with higher advance rates against certain assets and higher commitment and borrowing costs (the "Incremental Facility"). On July 25, 2017, the maturity date of the Incremental Facility was extended by one year to August 22, 2018, in accordance with the terms of the Credit Agreement. This maturity date may be extended for an additional 365 days on an annual basis with the consent of the lenders who agree to extend their commitments under the Incremental Facility.

The Credit Agreement has a sub-limit of $400 million for foreign currency borrowings, with up to $50 million available for foreign currency borrowings under the Agency Credit Facility and up to $350 million available for foreign currency borrowings under the SFS Credit Facility. The Credit Agreement also includes an accordion feature, which allows us to seek an increase to the borrowing capacity of the Credit Agreement until February 23, 2020 by an amount not to exceed $150 million in the aggregate. Though new commitments would need to be obtained, the uncommitted accordion feature permits us to seek an increase to the aggregate commitments of the Credit Agreement under an expedited arrangement process.

The borrowing base under the Agency Credit Facility is determined by a calculation that is primarily based upon a percentage of the carrying values of certain auction guarantee advances (see Note 4), a percentage of the carrying value of certain inventory, a percentage of the carrying value of certain extended payment term receivables arising from auction or private sale transactions (see Note 4), and the fair value of certain of our trademarks. The borrowing base under the Incremental Facility is determined by a calculation that is based on a percentage of the carrying values of certain inventory and the fair value of certain of our trademarks. The borrowing base under the SFS Credit Facility is determined by a calculation that is primarily based upon a percentage of the carrying value of certain SFS loans (see Note 4) and the fair value of certain of our trademarks.

The obligations under the Credit Agreements are cross-guaranteed and cross-collateralized. Domestic borrowers are jointly and severally liable for all obligations under the Credit Agreement and, subject to certain limitations, borrowers in the U.K. and Sotheby's Hong Kong Limited, are jointly and severally liable for all obligations of the foreign borrowers under the Credit Agreement. In addition, the obligations of the borrowers under the Credit Agreement are guaranteed by certain of their subsidiaries. Our obligations under the Credit Agreement are secured by liens on all or substantially all of the personal property of the entities that are borrowers and guarantors under the Credit Agreement.

The Credit Agreement contains certain customary affirmative and negative covenants including, but not limited to, limitations on capital expenditures, a $600 million limitation on net outstanding auction guarantees (i.e., auction guarantees less the impact of related risk and reward sharing arrangements), and limitations on the use of proceeds from borrowings under the Credit Agreement.

The Credit Agreement does not limit dividend payments and common stock repurchases provided that, both before and after giving effect thereto: (i) there are no events of default, (ii) the aggregate available borrowing capacity equals or exceeds $100 million, and (iii) the Liquidity Amount, as defined in the Credit Agreement, equals or exceeds $200 million. The Credit Agreement also contains certain financial covenants, which are only applicable during certain defined compliance periods. These financial covenants were not applicable for the twelve month period ended June 30, 2017.

Since August 2009, we have incurred aggregate fees of approximately $21.7 million in conjunction with the establishment of and subsequent amendments to the Credit Agreement. These fees are being amortized on a straight-line basis through the August 22, 2020 maturity date of the Credit Agreement. As of June 30, 2017, $6.8 millionofsuch unamortized fees are included within Other Long-Term Assets on our Condensed Consolidated Balance Sheets.

The following tables summarize information related to the Credit Agreement as of and for the periods ended June 30, 2017, December 31, 2016, and June 30, 2016 (in thousands of dollars):

Total Long-Term Debt, net	$	563,762		$	598,941		$	601,944

See the captioned sections below for information related to the York Property Mortgage and the 2022 Senior Notes.

York Property Mortgage—On February 6, 2009, we purchased the land and building located at 1334 York Avenue, New York, New York (the "York Property") from RFR Holding Corp. ("RFR") for a purchase price of $370 million. The York Property is home to our sole North American auction salesroom and principal North American exhibition space, including S|2, our private sale exhibition gallery. The York Property is also home to the U.S. operations of SFS, as well as our corporate offices.

We financed the $370 million purchase price through an initial $50 million cash payment made in conjunction with the signing of the related purchase and sale agreement on January 11, 2008, an $85 million cash payment made when the purchase was consummated on February 6, 2009, and the assumption of a $235 million mortgage that carried an initial annual rate of interest of approximately 5.6% (the "Original York Property Mortgage"). The Original York Property Mortgage was due to mature on July 1, 2035, but had an optional pre-payment date of July 1, 2015, after which the annual rate of interest was scheduled to increase to 10.6%.

On July 1, 2015, we entered into a seven-year, $325 million mortgage loan (the "York Property Mortgage") to refinance the Original York Property Mortgage. After the repayment of the Original York Property Mortgage and the funding of all closing costs, reserves, and expenses, we received net cash proceeds of approximately $98 million. The York Property Mortgage bears interest based on the one-month LIBOR rate (the "LIBOR rate") plus a spread of 2.25% and is being amortized based on a 25-year mortgage-style amortization schedule over its seven-year term. On June 21, 2017, the York Property Mortgage was amended to reduce the minimum net worth that Sotheby's is required to maintain from $425 million to $325 million in order to provide continued flexibility regarding potential future share repurchases. In conjunction with this amendment, on July 3, 2017, we made a partial prepayment of $32 million to reduce the outstanding principal balance of the York Property Mortgage, and agreed to make annual prepayments beginning in July 2018 and continuing through July 2021 that are not to exceed $25 million in the aggregate during that period. The $32 million payment made on July 3, 2017 was funded with $25 million from existing cash balances and $7 million from a restricted cash management account associated with the York Property Mortgage. Any prepayments made during the period July 2018 to July 2021 will also be funded from the restricted cash management account. See below for information related to the cash management account associated with the York Property Mortgage.

In connection with the York Property Mortgage, we entered into interest rate protection agreements secured by the York Property, consisting of a two-year interest rate swap effective as of July 1, 2015 and a five-year interest rate collar effective as of July 1, 2017. In conjunction and concurrent with the June 2017 amendment to the York Property Mortgage, the notional amount of the interest rate collar was reduced by $57 million to reflect: (i) the $32 million prepayment made on the York Property Mortgage on July 3, 2017 and (ii) potential annual prepayments of $6.25 million each beginning in July 2018 and continuing through July 2021. See Note 8 for additional information related to the interest rate protection agreements.

The York Property, the York Property Mortgage, and the related interest rate protection agreements are held by 1334 York, LLC (the "LLC"), a separate legal entity of Sotheby's that maintains its own books and records and whose results are ultimately consolidated into our Condensed Consolidated Financial Statements. The LLC is the sole owner and lessor of the York Property. The LLC presently leases the York Property to Sotheby's, Inc., which is also controlled by Sotheby's. The assets of the LLC are not available to satisfy the obligations of our other affiliates or any other entity.

The loan agreement governing the York Property Mortgage contains the following financial covenants, which are subject to additional terms and conditions as provided in the underlying loan agreement:

• As of July 1, 2020, the LTV ratio (i.e., the principal balance of the York Property Mortgage divided by the appraised value of the York Property) may not exceed 65% (the "Maximum LTV") based on the then-outstanding principal balance of the York Property Mortgage. If the LTV ratio exceeds the Maximum LTV, the LLC may, at its option, post cash or a letter of credit or pay down the York Property Mortgage without any prepayment penalty or premium, in an amount that will cause the LTV ratio not to exceed the Maximum LTV.

• At all times during the term of the York Property Mortgage, the Debt Yield will not be less than 8.5% (the "Minimum Debt Yield"). The Debt Yield is calculated by dividing the annual net operating income of the LLC, which primarily consists of lease income from Sotheby's, Inc. (calculated on a cash basis), by the outstanding principal balance of the York Property Mortgage. If the Debt Yield falls below the Minimum Debt Yield, the LLC has the option to post cash or a letter of credit or prepay the York Property Mortgage without any prepayment penalty or premium, in an amount that will cause the Debt Yield to exceed the Minimum Debt Yield.

• If Sotheby's corporate credit rating from Standard & Poor’s Rating Services ("S&P") is downgraded to "BB-", the lender may require that the LLC establish cash management accounts (the "Cash Management Accounts") under the lender's control for potential monthly debt service, insurance, and tax payments. If the rating is downgraded to "B+" or "B", the lender may require the LLC to deposit a certain amount of debt service into the Cash Management Accounts (approximately 6 and 12 months of debt service, respectively). If the rating is downgraded to lower than "B", the LLC must make principal payments on the mortgage such that the LTV ratio does not exceed 65%. On February 9, 2016, our corporate credit rating from S&P was downgraded to "BB-" from "BB". As a result, a Cash Management Account was established under the control of the lender for monthly debt service, insurance, and tax payments. The lender will retain any excess cash after debt service, insurance, and taxes as security. As of June 30, 2017, December 31, 2016, and June 30, 2016, the Cash Management Account had a balance of $7.4 million, $4.6 million, and $2.3 million, respectively, which is reflected within Restricted Cash on our Condensed Consolidated Balance Sheets. On July 3, 2017, $7 million from the Cash Management Account was used to fund a portion of the $32 million prepayment of the York Property Mortgage discussed above.

• Prior to June 21, 2017, Sotheby's was required to maintain a net worth of at least $425 million, subject to a cure period. As discussed above, on June 21, 2017, the York Property Mortgage was amended to reduce this $425 million requirement to $325 million.

As of June 30, 2017, the fair value of the York Property Mortgage approximated its book value due to the variable interest rate associated with the mortgage. The fair value measurement is considered to be a Level 2 fair value measurement in the fair value hierarchy as per ASC 820, Fair Value Measurements.

2022 Senior Notes—On September 27, 2012, we issued $300 million aggregate principal amount of 5.25% Senior Notes, due October 1, 2022 (the "2022 Senior Notes"). The 2022 Senior Notes were offered only to qualified institutional buyers in accordance with Rule 144A and to non-U.S. Persons under Regulation S under the Securities Act of 1933, as amended (the "Securities Act"). Holders of the 2022 Senior Notes do not have registration rights, and the 2022 Senior Notes have not been and will not be registered under the Securities Act.

The net proceeds from the issuance of the 2022 Senior Notes were approximately $294.6 million, after deducting fees paid to the initial purchasers, and were principally used to retire $80 million of unsecured debt that was due in June 2015 and $182 million of convertible debt that was due in June 2013.

The 2022 Senior Notes are guaranteed, jointly and severally, on a senior unsecured basis by certain of our existing and future domestic subsidiaries to the extent and on the same basis that such subsidiaries guarantee borrowings under the Credit Agreement. Interest on the 2022 Senior Notes is payable semi-annually in cash on April 1 and October 1 of each year.

We may redeem the 2022 Senior Notes, in whole or in part, on or after October 1, 2017, at specified redemption prices set forth in the underlying indenture, plus accrued and unpaid interest to, but excluding, the redemption date. Prior to October 1, 2017, we may redeem the 2022 Senior Notes, in whole or in part, at a redemption price equal to 100% of the principal amount to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date, plus a premium equal to the greater of 1% of the principal amount of the 2022 Senior Notes and a make-whole premium (as defined in the underlying indenture). The 2022 Senior Notes are not callable by holders unless we are in default under the terms of the underlying indenture.

As of June 30, 2017, the $300 million principal amount of the 2022 Senior Notes had a fair value of approximately $301.5 million based on a broker quoted price derived via a pricing model using observable and unobservable inputs. As such, this fair value measurement is considered to be a Level 3 fair value measurement in the fair value hierarchy as per ASC 820.

Future Principal and Interest Payments—The aggregate future principal and interest payments due under the Credit Agreement, the York Property Mortgage, and the 2022 Senior Notes during the five-year period after June 30, 2017 are as follows (in thousands of dollars):

Period	Amount
July 2017 to June 2018	$	65,337
July 2018 to June 2019	$	39,362

July 2020 to June 2021	$	570,569
July 2021 to June 2022	$	38,927

The table above assumes that the annual interest rate for the York Property Mortgage will be at the interest rate collar's floor rate of 4.167% for the remainder of the mortgage term.

See the captioned sections below for information related to derivative financial instruments designated as cash flow hedges or as net investment hedges.

Derivative Financial Instruments Designated as Cash Flow Hedges—On July 1, 2015, we entered into a seven-year, $325 million mortgage loan to refinance the previous mortgage on the York Property. The York Property Mortgage bears interest based on the one-month LIBOR rate plus a spread of 2.25% and is being amortized based on a 25-year mortgage-style amortization schedule over its seven-year term. On June 21, 2017, the York Property Mortgage was amended to reduce the minimum net worth that Sotheby's is required to maintain from $425 million to $325 million in order to provide continued flexibility regarding potential future share repurchases. In conjunction with this amendment, on July 3, 2017, we made a partial prepayment of $32 million to reduce the outstanding principal balance of the York Property Mortgage, and agreed to make annual prepayments beginning in July 2018 and continuing through July 2021 that are not to exceed $25 million in the aggregate during that period. The $32 million payment made on July 3, 2017 was funded with $25 million from existing cash balances and $7 million from a restricted cash management account related to the mortgage. Any prepayments made during the period July 2018 to July 2021 will also be funded from the restricted cash management account. See Note 7 for information on the restricted cash management account related to the York Property Mortgage.

In connection with the York Property Mortgage, we entered into interest rate protection agreements secured by the York Property, consisting of a two-year interest rate swap (the "Mortgage Swap"), effective as of July 1, 2015, and a five-year interest rate collar (the "Mortgage Collar"), effective as of July 1, 2017. These interest rate protection agreements effectively fix the LIBOR rate on the York Property Mortgage at an annual rate equal to 0.877% for the first two years, and then at an annual rate of no less than 1.917%, but no more than 3.75%, for the remainder of the seven-year term. After taking into account the interest rate protection agreements, the annual interest rate for the first two years of the York Property Mortgage was approximately 3.127% and then will be between a floor of 4.167% and a cap of 6% for the remaining seven-year term.

In conjunction and concurrent with the June 2017 amendment to the York Property Mortgage, the notional amount of the Mortgage Collar was reduced by $57 million to reflect: (i) the $32 million prepayment made on the York Property Mortgage on July 3, 2017 and (ii) potential annual prepayments of $6.25 million each beginning in July 2018 and continuing through July 2021. The reduced notional amount of the Mortgage Collar relates to the previously forecasted interest payments that are no longer probable of occurring as a result of the June 2017 amendment to the York Property Mortgage. This reduction in the notional amount of the Mortgage Collar resulted in a $0.6 million (net of tax) reclassification from Accumulated Other Comprehensive Loss into Net Income in the second quarter of 2017.

As of June 30, 2017, the notional value of the Mortgage Swap was $311 million and the notional value of the Mortgage Collar was $278.3 million. As of June 30, 2017, the Mortgage Swap and the Mortgage Collar each have a notional amount that is no greater than the applicable forecasted principal balance of the York Property Mortgage. The York Property, the York Property Mortgage, and the related interest rate protection agreements are held by 1334 York, LLC, a separate legal entity of Sotheby's that maintains its own books and records and whose results are ultimately consolidated into our financial statements.

On November 21, 2016, we entered into a two-year interest rate swap agreement (the “SFS Swap”) to eliminate the variability in expected cash outflows associated with the one-month LIBOR indexed interest payments owed on $63 million of SFS Credit Facility borrowings. As of June 30, 2017, the notional value of the SFS Swap was $63 million. See Note 7 for additional information related to the SFS Credit Facility.

At their inception, the Mortgage Swap, the Mortgage Collar, and the SFS Swap (collectively, the "Cash Flow Hedges") were each individually designated as cash flow hedges of the risk associated with the variability in expected cash outflows related to the one-month LIBOR-indexed interest payments owed on their respective debt instruments. Accordingly, to the extent that each of the Cash Flow Hedges is effective, any unrealized gains and losses related to changes in their fair value are recorded to Accumulated Other Comprehensive Loss on our Condensed Consolidated Balance Sheets and then reclassified to Interest Expense in our Condensed Consolidated Income Statements in the same period that interest expense related to the underlying debt instruments is recorded. Any hedge ineffectiveness is immediately recognized in Net Income. In addition, if any of the forecasted transactions associated with the Cash Flow Hedges are no longer probable of occurring, any related amounts previously recorded in Accumulated Other Comprehensive Loss on our Condensed Consolidated Balance Sheets would be immediately reclassified into Net Income. As discussed above, certain previously forecasted interest payments associated with the Mortgage Collar became no longer probable of occurring in the second quarter of 2017 and, as a result, $0.6 million (net of tax) of the amount previously recorded in Accumulated Other Comprehensive Loss was immediately reclassified into Net Income.

Management performs a quarterly assessment to determine whether each of the Cash Flow Hedges continues to be highly effective in hedging the risk associated with the variability in expected cash outflows related to the one-month LIBOR-indexed interest payments on their respective debt instruments. As of June 30, 2017, each of the Cash Flow hedges, including the Mortgage Collar, as amended, is expected to continue to be highly effective in hedging the risk associated with the variability in expected cash outflows related to the one-month LIBOR-indexed interest payments on their respective debt instruments.

The assets and liabilities associated with the Cash Flow Hedges have been designated as Level 2 fair value measurements within the fair value hierarchy provided by ASC 820. Level 2 fair value measurements have pricing inputs other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date. Level 2 fair value measurements may be determined through the use of models or other valuation methodologies. The fair value of the Mortgage Swap is based on a discounted cash flow methodology using the contractual terms of the instrument and observable LIBOR-curve rates that are consistent with the timing of the interest payments related to the York Property Mortgage. The fair value of the Mortgage Collar is based on an option pricing model using observable LIBOR-curve rates for each forecasted monthly settlement, with the projected cash flows discounted using the contractual terms of the instrument. The fair value of the SFS Swap is based on a discounted cash flow methodology using the contractual terms of the instrument and observable LIBOR-curve rates that are consistent with the timing of the interest payments related to the SFS Credit Facility.

Derivative Financial Instruments Designated as Net Investment Hedges—We are exposed to variability in the U.S. Dollar equivalent of the net investments in our foreign subsidiaries and, by extension, the U.S. Dollar equivalent of any foreign earnings repatriated to the U.S. due to potential changes in foreign currency exchange rates. As a result, we regularly enter into foreign currency forward exchange contracts to hedge the net investments in our foreign subsidiaries from which we expect to repatriate earnings to the U.S. As of June 30, 2017, the aggregate notional value of our outstanding net investment hedge contracts was $49.7 million.

We use the forward rate method to assess the effectiveness of our net investment hedges. Under the forward rate method, if both the notional amount of the derivative designated as a hedge of a net investment in a foreign subsidiary equals the portion of the net investment designated as being hedged and the derivative relates solely to the foreign exchange rate between the functional currency of the hedged net investment and the investor’s functional currency, then all changes in fair value of the derivative are reported in the cumulative translation adjustment accounts within Accumulated Other Comprehensive Loss on our Condensed Consolidated Balance Sheets.

The foreign currency forward exchange contracts designated as net investment hedges are considered Level 2 fair value measurements within the fair value hierarchy provided by ASC 820. Level 2 fair value measurements have pricing inputs other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value may be determined through the use of models or other valuation methodologies. The fair value of these foreign currency forward exchange contracts is based on the estimated amount to settle the contracts using applicable market exchange rates as of the balance sheet date.

Derivative Financial Instruments Not Designated as Hedging Instruments—We also utilize forward contracts to hedge cash flow exposures related to foreign currency exchange rate movements arising from short-term foreign currency denominated intercompany balances and, to a much lesser extent, foreign currency denominated client payable balances, as well as foreign currency denominated auction guarantee obligations. Such forward exchange contracts are typically short-term with settlement dates less than six months from their inception. These instruments are not designated as hedging instruments for accounting purposes. Accordingly, changes in the fair value of these instruments are recognized in our Condensed Consolidated Income Statements in Non-Operating Income.

As of June 30, 2017, the notional value of outstanding forward exchange contracts not designated as hedging instruments was $197.9 million. Notional values do not quantify risk or represent our assets or liabilities, but are used to calculate cash settlements under outstanding forward exchange contracts. We are exposed to credit-related risks in the event of nonperformance by the counterparties to our outstanding forward exchange contracts that are not designated as hedging instruments. We do not expect either of these counterparties to fail to meet their obligations, given their high short-term (A1/P1) credit ratings. As of June 30, 2017, December 31, 2016, and June 30, 2016 the aggregate fair value of these contracts represented liabilities of $1.4 million, $3.6 million, and $3.7 million, respectively, which were recorded on our Condensed Consolidated Balance Sheets within Accounts Payable and Accrued Liabilities.

Sale of Pink Diamond

Sale of Pink Diamond

Our reported inventory balances include a Fancy Vivid Pink Diamond (the "Pink Diamond") with a carrying value of $68.4 million. In the second quarter of 2016, we sold an undivided legal and beneficial 50% ownership interest in the Pink Diamond for $34.2 million in cash. In April 2017, at our Magnificent Jewels and Jadeite Sale in Hong Kong (the "Auction"), the Pink Diamond was sold for a total purchase price of approximately $71.2 million (the "Purchase Price"). The purchaser of the Pink Diamond, who is one of the largest jewelery retailers in the world, is legally obligated to pay the Purchase Price by no later than April 4, 2018.

Although the Auction occurred in the second quarter of 2017, the sale will not be recognized in our financial statements until we collect the Purchase Price and transfer title and possession of the Pink Diamond to the purchaser. Until that time, the Pink Diamond will continue to be reported on our balance sheet within Inventory at its $68.4 million carrying value, with the $34.2 million cash payment received in the second quarter of 2016 recorded within Other Current Liabilities. When payment is collected and the related revenue is recognized in our financial statements, the sale of the Pink Diamond will result in a gain of approximately $0.5 million, after taking into account the associated Cost of Inventory Sales of $70.7 million, which includes amounts due to our partner and other costs related to the sale.

The timing of further share repurchases and the actual amount purchased will depend on a variety of factors including the market price of our common stock, general market and economic conditions, securities law requirements, and other corporate considerations. Repurchases may continue to be made pursuant to plans intended to comply with Rule 10b5-1 under the Exchange Act, which allows us to purchase our shares during periods when we otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods. The repurchase authorization does not require the purchase of a specific number of shares and is subject to suspension or termination by our Board of Directors at any time.

Special Dividend—On January 29, 2014, the Board of Directors declared a special dividend of $300 million ($4.34 per share) that was paid on March 17, 2014. In conjunction with this special dividend, approximately $11 million was accrued for dividend equivalents owed on share-based payments to employees, which was charged to retained earnings. For the six months ended June 30, 2017 and 2016, approximately $2 million and $1.4 million, respectively, of such accrued dividend equivalents were paid upon the vesting of the underlying awards.

Commitments and Contingencies

Commitments and Contingencies

Compensation Arrangements—We are party to compensation arrangements with certain senior employees, which expire at various points between October 26, 2017 and January 11, 2021. Such arrangements may provide, among other benefits, for minimum salary levels and for compensation under our incentive compensation programs that is payable only if specified Company and individual goals are attained. Additionally, under certain circumstances, certain of these arrangements provide annual share-based payments, severance payments, and other cash compensation. The aggregate remaining commitment for salaries and other cash compensation related to these compensation arrangements, excluding any participation in our incentive compensation programs, was approximately $15.4 million as of June 30, 2017.

Tax Contingencies—We are subject to laws and regulations in many countries involving sales, use, value-added and other indirect taxes which are assessed by various governmental authorities and imposed on certain revenue-producing transactions between us and our clients. The application of these laws and regulations to our unique business and global client base, and the estimation of any related liabilities, is complex and requires a significant amount of judgment. We are generally not responsible for these indirect tax liabilities unless we fail to collect the correct amount of sales, value-added, or other indirect taxes. Failure to collect the correct amount of indirect tax on a transaction may expose us to claims from tax authorities and could require us to record a liability and corresponding charge to our income statement.

Legal Contingencies—We become involved in various claims and lawsuits incidental to the ordinary course of our business. We are required to assess the likelihood of any adverse judgments or outcomes related to these legal contingencies, as well as potential ranges of probable or reasonably possible losses. The determination of the amount of any losses to be recorded or disclosed as a result of these contingencies is based on a careful analysis of each individual exposure with, in some cases, the assistance of outside legal counsel. The amount of losses recorded or disclosed for such contingencies may change in the future due to new developments in each matter or a change in settlement strategy. While the impact of any one or more legal claims or proceedings could be material to our operating results in any period, we do not believe that the outcome of any of these pending claims or proceedings, individually or in the aggregate, will have a material adverse effect on our consolidated financial condition.

See Note 4 for information related to unfunded commitments to extend additional loans through SFS. See Note 7 for information related to debt commitments. See Note 15 for information related to income tax contingencies. See Note 16 for information related to auction guarantees.

Income Tax Uncertainties [Abstract]

Uncertain Tax Positions

Uncertain Tax Positions

As of June 30, 2017, our liability for unrecognized tax benefits, excluding interest and penalties, was $20.4 million, representing a net increase of $0.9 million when compared to a liability of $19.5 million as of December 31, 2016. This net increase is primarily the result of the accrual of tax reserves related to transfer pricing and other U.S. federal and state and non-U.S. matters, partially offset by the expiration of the statute of limitations for certain tax years and the favorable settlement of tax audits. As of June 30, 2016, the liability for unrecognized tax benefits, excluding interest and penalties, was $19.5 million.

As of June 30, 2017, December 31, 2016, and June 30, 2016, the total amount of unrecognized tax benefits that, if recognized, would favorably affect our effective income tax rate was $9.6 million, $9.3 million, and $13.7 million, respectively. We believe it is reasonably possible that a decrease of $10.1 million in the balance of unrecognized tax benefits can occur within 12 months of the June 30, 2017 balance sheet date as a result of the expiration of statutes of limitations and the expected settlement of ongoing tax audits.

We are subject to taxation in the U.S., as well as in various U.S. state and foreign jurisdictions. As a result, we are subject to tax audits in these jurisdictions. We are currently under examination by various U.S. state and foreign taxing authorities. The earliest open tax year for the major jurisdictions in which we do business, which includes the U.S. (including various state and local jurisdictions), the U.K., and Hong Kong, is 2009.

We recognize interest expense and penalties related to unrecognized tax benefits as a component of Income Tax Expense. The accrual for such interest and penalties increased by $0.5 million for the six months ended June 30, 2017.

Our policy is to record interest expense related to sales, value added and other non-income based taxes as Interest Expense in our Condensed Consolidated Income Statements. Penalties related to such taxes are recorded as General and Administrative Expenses in our Condensed Consolidated Income Statements. Interest expense and penalties related to income taxes are recorded as a component of Income Tax Expense in our Condensed Consolidated Income Statements.

Auction Guarantees

Guarantees [Abstract]

Auction Guarantees

Auction Guarantees

From time-to-time in the ordinary course of our business, we will guarantee to a consignor a minimum sale price in connection with the sale of property at auction (an "auction guarantee"). If the property offered under the auction guarantee sells above the minimum guaranteed price, we are generally entitled to a share of the excess proceeds (the "overage"). In the event that the property sells for less than the minimum guaranteed price, we must perform under the auction guarantee by funding the difference between the sale price at auction and the amount of the auction guarantee (the "shortfall"). The amount of any shortfall recorded in our Condensed Consolidated Income Statements is reduced by any auction commissions earned on property sold under the auction guarantee. If any item of property offered under the auction guarantee does not sell, the amount of the auction guarantee must be paid, but we take ownership of the unsold property and may recover the amount paid through its future sale. In certain limited situations, if the guaranteed property fails to sell at auction or if the purchaser defaults, the consignor has the right to cancel the auction guarantee and retain the property. Depending on the mix of items subject to an auction guarantee, in advance of peak selling seasons, a small number of guaranteed items may represent a substantial portion of the aggregate amount of outstanding auction guarantees.

In situations when an item of guaranteed property does not sell and we take ownership of the property, it is recorded as Inventory on our Condensed Consolidated Balance Sheets at the lower of its cost (i.e., the amount paid under the auction guarantee) or our estimate of the property's net realizable value (i.e., the expected sale price upon its eventual disposition). The market for fine art, decorative art, and jewelry is not a highly liquid trading market. As a result, the valuation of property acquired as a result of failed auction guarantees is inherently subjective and its realizable value often fluctuates over time. Accordingly, the proceeds ultimately realized on the sale of previously guaranteed property may equal, exceed, or be less than the estimated net realizable value recorded as Inventory on our Condensed Consolidated Balance Sheets.

We may reduce our financial exposure under auction guarantees through contractual risk and reward sharing arrangements. Such auction guarantee risk and reward sharing arrangements include irrevocable bids and partner sharing arrangements. An irrevocable bid is an arrangement under which a counterparty commits to bid a predetermined price on the guaranteed property. If the irrevocable bid is not the winning bid, the counterparty is generally entitled to receive a share of the auction commission earned on the sale and/or a share of any overage. If the irrevocable bid is the winning bid, the counterparty may receive a fixed fee as compensation for providing the irrevocable bid. This fee may be netted against the counterparty's obligation to pay the full purchase price (i.e., the hammer price plus the applicable buyer's premium). In a partner sharing arrangement, a counterparty commits to fund: (i) a share of the difference between the sale price at auction and the amount of the auction guarantee if the property sells for less than the minimum guaranteed price or (ii) a share of the minimum guaranteed price if the property does not sell while taking ownership of a proportionate share of the unsold property. In exchange for accepting a share of the financial exposure under the auction guarantee, the counterparty in a partner sharing arrangement is generally entitled to receive a share of the auction commission earned if the property sells and/or a share of any overage.

The counterparties to our auction guarantee risk and reward sharing arrangements are typically major international art dealers or major art collectors. We could be exposed to losses in the event any of these counterparties do not perform according to the terms of these contractual arrangements.

Although irrevocable bid and partner sharing arrangements may be used to reduce the risk associated with auction guarantees, we may also enter into auction guarantees without securing such arrangements. In these circumstances, we could be exposed to deterioration in auction commission margins and/or auction guarantee losses if one or more of the guaranteed items fails to sell at its minimum guaranteed price. Furthermore, in such situations, our liquidity could be reduced.

Our credit agreement has a covenant that imposes a $600 million limitation on net outstanding auction guarantees (i.e., the aggregate financial exposure under outstanding auction guarantees less the impact of related risk and reward sharing arrangements). In addition to compliance with this covenant, significant auction guarantees and related risk and reward sharing arrangements are subject to approval by our Board of Directors.

As of June 30, 2017, we had outstanding auction guarantees totaling $9.8 million. Our financial exposure under these auction guarantees is reduced by irrevocable bids totaling $2.7 million. Each of the outstanding auction guarantees has a minimum guaranteed price that is within or below the range of the pre-sale auction estimates for the underlying property. The property related to these auction guarantees is being offered at auctions during the fourth quarter of 2017.

We are obligated under the terms of certain auction guarantees to advance all or a portion of the guaranteed amount prior to auction. As of June 30, 2017 and December 31, 2016, the estimated fair value of our obligation to perform under our outstanding auction guarantees totaled $0.4 million and $0.6 million, respectively, and is recorded within Accounts Payable and Accrued Liabilities on our Condensed Consolidated Balance Sheets. As of June 30, 2016, the liability related to our obligation to perform under our outstanding auction guarantees was not material.

As of August 2, 2017, we had outstanding auction guarantees totaling $17 million and, as of that date, our financial exposure was reduced by irrevocable bids totaling $2.7 million. Each of the auction guarantees outstanding as of August 2, 2017, had a minimum guaranteed price that was within or below the range of the pre-sale auction estimates for the underlying property. The property related to these auction guarantees is being offered at auctions in the fourth quarter of 2017. As of August 2, 2017, we have advanced $1.1 million of the total guaranteed amount.

Share-Based Payments

Share-based Compensation [Abstract]

Share-Based Payments

Share-Based Payments

Share-Based Payments—Share-based payments made to employees include performance-based stock unit awards, market-based stock unit awards, restricted stock units, restricted shares, and stock options. Share-based payments are also made to members of our Board of Directors through the issuance of deferred stock units. A description of each of these share-based payments is provided below.

For the three and six months ended June 30, 2017 and 2016, compensation expense for share-based payments made to employees was reflected in the following accounts in our Condensed Consolidated Income Statements (in thousands of dollars):

	Three Months Ended June 30,					Six Months Ended June 30,
	2017		2016			2017		2016
Salaries and related costs	$	5,946	$	2,291		$	12,015	$	8,128
Voluntary separation incentive programs	—		(334		)	—		(640		)
Total share-based payment expense (pre-tax)	$	5,946	$	1,957		$	12,015	$	7,488
Total share-based payment expense (after-tax)	$	3,940	$	1,609		$	7,997	$	5,410

For the three and six months ended June 30, 2016, our Condensed Consolidated Income Statements include credits of ($0.3) million and ($0.6) million, respectively, related to the voluntary separation incentive programs enacted in the fourth quarter of 2015. These credits were the result of changes in our estimate of the number of performance-based stock units held by program participants that were expected to vest.

As discussed in Note 1, on January 1, 2017, we adopted ASU 2016-09, Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 requires, among other things, that all excess tax benefits and deficiencies resulting from the vesting of share-based payments be recorded in the statement of operations, whereas previous guidance generally permitted such items to be recorded in the equity section of the balance sheet provided that an adequate level of previously recorded excess tax benefits existed. This aspect of ASU 2016-09 was adopted on a prospective basis.

For the six months ended June 30, 2017, we recognized a $2.6 million excess tax benefit related to share-based payment in our Condensed Consolidated Income Statements. This tax benefit represents the amount by which the tax deduction resulting from the vesting of share-based payments in the period exceeded the tax benefit initially recognized in our Condensed Consolidated Financial Statements.

For the six months ended June 30, 2016, we recognized a ($1.3) million tax shortfall related to share-based payment. This tax shortfall represents the amount by which the tax deduction resulting from the vesting of share-based payments in the period was less than the tax benefit initially recognized in our Condensed Consolidated Financial Statements. As discussed above, prior to the adoption of ASU 2016-09 on January 1, 2017, such tax shortfalls were accounted for as a reduction to previously recorded excess tax benefits related to share-based payments within Additional Paid-in Capital on our Condensed Consolidated Balance Sheets.

As of June 30, 2017, unrecognized compensation expense related to the unvested portion of share-based payments to employees was $33.3 million. This compensation expense is expected to be amortized over a weighted-average period of approximately 2.4 years. We do not capitalize any compensation expense related to share-based payments to employees.

Restricted Stock Unit Plan—The Sotheby's Restricted Stock Unit Plan (as amended and restated, the "Restricted Stock Unit Plan") provides for the issuance of restricted stock units ("RSU's") and restricted shares to employees. Awards made under the Restricted Stock Unit Plan are subject to the approval of the Compensation Committee of our Board of Directors (the "Compensation Committee"). In making awards under the Restricted Stock Unit Plan, the Compensation Committee takes into account the nature of the services rendered by employees, their present and potential future contributions to Sotheby's success, and such other factors as the Compensation Committee in its discretion deems relevant.

RSU's and restricted shares issued under the Restricted Stock Unit Plan generally vest evenly over a three-year service period. Prior to vesting, holders of RSU's and restricted shares are entitled to receive non-forfeitable dividend equivalents and dividends, respectively, at the same rate as dividends are paid on our common stock (if and when such dividends are paid). Prior to vesting, holders of RSU's do not have voting rights, while holders of restricted shares have voting rights. RSU's and restricted shares may not be sold, assigned, transferred, pledged or otherwise encumbered until they vest.

Performance Share Units (or "PSU's") are RSU's that generally vest over three or four-year service periods, subject to the achievement of certain profitability targets (for awards granted prior to 2016) or certain return on invested capital ("ROIC") targets (for awards granted beginning in 2016). Prior to vesting, holders of PSU's do not have voting rights and are not entitled to receive dividends or dividend equivalents. Dividend equivalents are generally credited to holders of PSU's at the same rate as dividends are paid on our common stock (if and when such dividends are paid), but are only paid for PSU's that vest and become shares of our common stock. PSU's may not be sold, assigned, transferred, pledged or otherwise encumbered until they vest.

For the six months ended June 30, 2017, the Compensation Committee approved share-based payment awards with a total grant date fair value of $30.8 million, as follows:

• 369,897 PSU's with a grant date fair value of $14.6 million and a single vesting opportunity after a three-year service period. These PSU's provide the recipient with an opportunity to vest in incremental PSU's of up to 100% of the initial units awarded subject to the achievement of certain ROIC targets, for a total maximum vesting opportunity of 200% of the initial award. The maximum number of shares of common stock that may be payable with respect to these awards is 739,794.

• 401,997 RSU's with a grant date fair value of $16.2 million and annual vesting opportunities over a three-year service period.

Summary of Outstanding Share-Based Payment Awards—For the six months ended June 30, 2017, changes to the number of outstanding RSU’s, PSU’s, and restricted shares were as follows (shares in thousands):

	Restricted Shares, RSU's and PSU's		Weighted Average Grant Date Fair Value
Outstanding at January 1, 2017	2,235		$	36.40
Granted	772		$	39.87
Vested	(754	)	$	39.07
Canceled	(183	)	$	38.88
Outstanding at June 30, 2017	2,070		$	36.50

As of June 30, 2017, 2.3 million shares were available for future awards issued pursuant to the Restricted Stock Unit Plan. The aggregate fair value of RSU’s and PSU's that vested during the six months ended June 30, 2017 and 2016 was $35.9 million and $13.8 million, respectively, based on the closing stock price on the dates the shares vested.

Stock Options—Stock options issued pursuant to the 1997 Stock Option Plan are exercisable into authorized, but unissued shares of our common stock. Stock options vest evenly over four years and expire ten years after the date of grant. As of June 30, 2017, 104,100 shares of our common stock were available for the issuance of stock options under the Stock Option Plan. As of June 30, 2017, 50,000 stock options were outstanding and exercisable with a weighted average exercise price of $22.11 per share, a weighted average remaining contractual term of 2.6years, and an aggregate intrinsic value of $1.6 million. No stock options were exercised or granted during the six months ended June 30, 2017 and 2016.

Directors Stock Plan—Common stock is issued quarterly under the Sotheby’s Stock Compensation Plan for Non-Employee Directors (as amended and restated, the “Directors Stock Plan”). Directors may elect to receive this compensation in the form of deferred stock units, which are credited in an amount that is equal to the number of shares of common stock the director otherwise would have received. The number of shares of common stock awarded is calculated using the closing price of the common stock on the New York Stock Exchange on the business day immediately prior to the quarterly grant date. Deferred stock units are held until a director’s termination of service, at which time the units are settled on a one-for one basis in shares of our common stock on the first day of the calendar month following the date of termination. For the three and six months ended June 30, 2017 and 2016, we recognized $0.3 million and $0.5 million, respectively, within General and Administrative Expenses in our Condensed Consolidated Income Statements related to common stock shares awarded under the Directors Stock Plan. As of June 30, 2017,158,917deferred stock units were outstanding under the Directors Stock Plan and 125,552units were available for future issuance.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share—Basic earnings per share attributable to Sotheby's common shareholders is computed under the two-class method using the weighted average number of common shares outstanding during the period. The two-class method requires that the amount of net income attributable to participating securities be deducted from consolidated net income in the computation of basic earnings per share. In periods with a net loss, the net loss attributable to participating securities is not deducted from consolidated net loss in the computation of basic earnings per share as the impact would be anti-dilutive. Our participating securities include unvested restricted stock units and unvested restricted shares held by employees, both of which have non-forfeitable rights to dividends (see Note 17).

Diluted earnings per share—Diluted earnings per share attributable to Sotheby's common shareholders is computed in a similar manner to basic earnings per share under the two-class method, using the weighted average number of common shares outstanding during the period and, if dilutive, the weighted average number of potential common shares outstanding during the period. Our potential common shares include unvested performance share units held by employees, incremental common shares issuable upon the exercise of employee stock options, and deferred stock units held by members of our Board of Directors (see Note 17).

For the three and six months ended June 30, 2017 and 2016, approximately 1 million potential common shares related to share-based payment awards were excluded from the computation of diluted earnings per share because the financial performance or stock price targets inherent in such awards were not achieved as of the respective balance sheet dates.

The table below summarizes the computation of basic and diluted earnings per share for the three and six months ended June 30, 2017 and 2016 (in thousands, except per share amounts):

Diluted earnings per share - Sotheby’s common shareholders	$	1.43	$	1.52	$	1.21	$	1.03

The decrease in weighted average common shares outstanding between the current and prior year reporting periods is due to common stock repurchases made throughout 2016 and in the second quarter of 2017. See Note 12 for additional information on our share repurchase program.

Acquisition of Art Agency, Partners

6 Months Ended

Business Combinations [Abstract]

Acquisition of Art Agency, Partners

Acquisition of Art Agency, Partners

On January 11, 2016, we acquired Art Agency, Partners, a firm that provides a range of art-related services, in exchange for initial cash consideration of $50 million and future earn-out payments of up to $35 million, as discussed in more detail below. The purpose of this acquisition is to grow auction and private sale revenues by enhancing our relationships with art collectors and by improving our position in the fine art market, particularly in Impressionist, Modern and Contemporary Art. Also, as a result of this acquisition, we have added a new revenue stream by integrating AAP's existing art advisory business, providing a new avenue for growth. The purchase agreement governing the acquisition of AAP includes non-competition and non-solicitation covenants that continue in effect until January 2021. In connection with this acquisition, each of the former principals of AAP also entered into a five-year employment agreement that extends through January 2021. Each employment agreement also includes non-competition and non-solicitation covenants that continue in effect for 12 months following the end of employment.

As indicated above, in connection with the acquisition of AAP, we agreed to make future earn-out payments to the former principals of AAP not to exceed $35 million in the aggregate, contingent on the achievement of a level of cumulative financial performance within the Impressionist, Modern and Contemporary Art collecting categories, as well as from AAP's art advisory business. Progress against the cumulative financial target (the "Target") was to be measured at the end of each calendar year during the four-year performance period following the acquisition, after adjusting the Target to reflect the annual growth or contraction of the auction market for Impressionist, Modern and Contemporary Art, when compared to the year ended December 31, 2015. Amounts owed pursuant to the earn-out arrangement are considered to be compensation expense for accounting purposes and are classified within Salaries and Related Costs in our Condensed Consolidated Income Statements.

For the three and six months ended June 30, 2016, we recognized $2.2 million and $4.4 million, respectively, of compensation expense associated with the AAP earn-out arrangement based on our initial estimate of progress against the Target. For the year ended December 31, 2016, we recognized $35 million of compensation expense associated with the AAP earn-out arrangement, reflecting the full achievement of the Target as a result of our improved market share in the Contemporary Art collecting category, as well as an improvement in auction commission margins, during the initial annual period. The $35 million owed under the earn-out arrangement is being paid in four annual increments of $8.75 million in the first quarter of each year beginning in 2017 and through 2020.The portion of the accrued liability due in the first quarter of 2018 ($8.75 million) is recorded within Accrued Salaries and Related Costs on our Condensed Consolidated Balance Sheets, and the remaining liability ($17.5 million) is recorded within Other Long-Term Liabilities. See Note 10.

The table below summarizes the allocation of the total purchase price paid for AAP to the assets acquired and liabilities assumed (in thousands of dollars):

Purchase price:
Initial cash consideration	$	50,000
Working capital adjustment	1,189
Total purchase price	$	51,189
Allocation of purchase price:
Net working capital acquired	$	1,572
Fixed assets and other long-term assets	173
Goodwill (see Note 5)	34,490
Intangible assets - customer relationships (see Note 5)	10,800
Intangible assets - non-compete agreements (see Note 5)	3,060
Deferred tax assets	1,094
Total purchase price	$	51,189

Upon completion of the purchase price allocation in the second quarter of 2016, $28.3 million of the resulting goodwill was allocated to the Agency segment and $6.2 million was allocated to the acquired art advisory business, which is reported within All Other for segment reporting purposes. The goodwill is tax deductible over a period of 15 years.

We incurred $0.8 million of transaction costs in connection with the acquisition of AAP, which were recognized within General and Administrative Expenses in the fourth quarter of 2015 ($0.6 million) and the first quarter of 2016 ($0.2 million).

It is impracticable to compute the amount of revenues and earnings contributed to the Agency segment as a result of the acquisition because the related activities have been integrated into the segment. Disclosure of pro-forma revenues and earnings attributable to the acquisition is also excluded because it is impracticable to determine since AAP was a closely-held private entity and its historical financial records are not available in U.S. GAAP.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recent Accounting Standards Not Yet Adopted

Recent Accounting Standards Not Yet Adopted

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which introduces a new five-step framework for revenue recognition. The core principal of the standard is that entities should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenue and cash flows arising from an entity's contracts with customers. ASU 2014-09 can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. On August 12, 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers - Deferral of Effective Date, which defers the effective date of ASU 2014-09 to January 1, 2018 with early adoption beginning January 1, 2017. We have identified all material contract types and are in the process of evaluating the impact of adopting ASU 2014-09. We expect to quantify and disclose the expected impact, if any, of adopting ASU 2014-09, in our Form 10-Q for the period ended September 30, 2017. Based on our progress to date, we do not expect the adoption of ASU 2014-09 to have a material impact on the timing of our revenue recognition. However, based on our preliminary conclusions, we anticipate a change in the classification of certain ancillary revenue streams currently recorded on a net basis in our income statement.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments, including requirements to measure most equity investments at fair value with changes in fair value recognized in net income, to perform a qualitative assessment of equity investments without readily determinable fair values, and to separately present financial assets and liabilities by measurement category and by type of financial asset on the balance sheet or in the accompanying notes to the financial statements. ASU 2016-01 will be effective for us beginning on January 1, 2018, and will be applied by means of a cumulative effect adjustment to the balance sheet, except for effects related to equity securities without readily determinable values, which will be applied prospectively. We are currently assessing the potential impact of adopting ASU 2016-01 on our financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases, which requires long-term lease arrangements to be recognized as assets and liabilities on the balance sheet of the lessee. Under ASU 2016-02, a right-of-use asset and lease obligation will be recorded for all long-term leases, whether operating or financing, while the income statement will reflect lease expense for operating leases and interest expense for financing leases. The amendments also require certain new quantitative and qualitative disclosures regarding leasing arrangements. ASU 2016-02 will be effective for us beginning on January 1, 2019. Lessees must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early adoption is permitted. We are currently assessing the potential impact of adopting ASU 2016-02 on our financial statements.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which amends previously issued guidance regarding the impairment of financial instruments by creating an impairment model that is based on expected losses rather than incurred losses. ASU 2016-13 is effective for us beginning on January 1, 2020. Early adoption is permitted. We are currently assessing the potential impact of adopting ASU 2016-13 on our financial statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, which updates guidance as to how certain cash receipts and cash payments should be presented and classified within the statement of cash flows. ASU 2016-15 is intended to reduce the existing diversity in practice and is effective for us beginning on January 1, 2018. Early adoption is permitted. We are currently assessing the potential impact of adopting ASU 2016-15 on our financial statements.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows, which amends ASC 230 to add or clarify guidance on the classification and presentation of restricted cash and restricted cash equivalents in the statement of cash flows. ASU 2016-18 is effective for us beginning on January 1, 2018. Early adoption is permitted. We are currently assessing the potential impact of adopting ASU 2016-18 on our financial statements.

In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business, which amends the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. ASU 2017-01 is effective for us beginning on January 1, 2018 and must be applied prospectively on or after the effective date. We do not expect the adoption of ASU 2017-01 to have a material impact on our financial statements.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit's carrying amount over its fair value. ASU 2017-04 is effective for us beginning on January 1, 2020. Early adoption is permitted. We do not expect the adoption of ASU 2017-04 to have a material impact on our financial statements.

In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which requires entities to disaggregate the current service cost component from the other components of net pension cost (the "other components") to be included in compensation costs in the income statement and present the other components elsewhere in the income statement and outside of income from operations, if that subtotal is presented. In addition, ASU 2017-07 requires entities to disclose the income statement lines that contain the other components if they are not presented on appropriately described separate lines. ASU 2017-07 is effective for us beginning on January 1, 2018. The adoption of ASU 2017-07 will result in the recording of the expected return on plan assets and the amortization of actuarial losses related to the U.K. Pension Plan outside of operating income. Currently, these components of net pension cost (credit) are recorded within Salaries and Related Costs. See Note 6.

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation: Scope of Modification Accounting, which amends the scope of modification accounting for share-based payment arrangements. ASU 2017-09 provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718, Compensation-Stock Compensation. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. We will apply ASU 2017-09 prospectively to any share-based payment awards modified on or after its January 1, 2018 effective date.
