NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1—THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

IAC is a leading media and Internet company comprised of widely known consumer brands, such as HomeAdvisor, Vimeo, Dotdash (formerly About.com), Dictionary.com, The Daily Beast, Investopedia, and Match Group's online dating portfolio, which includes Match, Tinder, PlentyOfFish and OkCupid.

All references to "IAC," the "Company," "we," "our" or "us" in this report are to IAC/InterActiveCorp.

On March 31, 2017, Match Group sold its non-dating business, consisting of The Princeton Review. The non-dating business does not meet the threshold to be reflected as a discontinued operation at the IAC level. The Company has moved the non-dating business to its “Other” segment as of and for the quarter ended March 31, 2017 and prior period segment data has been recast to conform to the current period presentation.

Basis of Presentation

The Company prepares its consolidated financial statements in accordance with U.S. generally accepted accounting principles ("GAAP").

Basis of Consolidation and Accounting for Investments

The consolidated financial statements include the accounts of the Company, all entities that are wholly-owned by the Company and all entities in which the Company has a controlling financial interest. Intercompany transactions and accounts have been eliminated.

Investments in the common stock or in-substance common stock of entities in which the Company has the ability to exercise significant influence over the operating and financial matters of the investee, but does not have a controlling financial interest, are accounted for using the equity method and are included in "Long-term investments" in the accompanying consolidated balance sheet.

The accompanying unaudited consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation. Interim results are not necessarily indicative of the results that may be expected for the full year. The accompanying unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016.

Accounting Estimates

Management of the Company is required to make certain estimates, judgments and assumptions during the preparation of its consolidated financial statements in accordance with GAAP. These estimates, judgments and assumptions impact the reported amounts of assets, liabilities, revenue and expenses and the related disclosure of contingent assets and liabilities. Actual results could differ from these estimates.

On an ongoing basis, the Company evaluates its estimates and judgments including those related to: the fair values of marketable securities and other investments; the recoverability of goodwill and indefinite-lived intangible assets; the useful lives and recoverability of definite-lived intangible assets and property and equipment; the carrying value of accounts receivable, including the determination of the allowance for doubtful accounts; the determination of revenue reserves; the fair value of acquisition-related contingent consideration arrangements; the liabilities for uncertain tax positions; the valuation allowance for deferred income tax assets; and the fair value of and forfeiture rates for stock-based awards, among others. The

Company bases its estimates and judgments on historical experience, its forecasts and budgets and other factors that the Company considers relevant.

Certain Risks and Concentrations

A significant portion of the Company's revenue is derived from online advertising, the market for which is highly competitive and rapidly changing. Significant changes in this industry or changes in advertising spending behavior or in customer buying behavior could adversely affect our operating results. Most of the Company's online advertising revenue is attributable to a services agreement with Google Inc. ("Google"). For the three months ended March 31, 2017 and 2016, revenue from Google represents 25% and 35%, respectively, of the Company's consolidated revenue. The Company's services agreement became effective on April 1, 2016, following the expiration of the previous services agreement. The services agreement expires on March 31, 2020; however, the Company may choose to terminate the agreement effective March 31, 2019. The services agreement requires that we comply with certain guidelines promulgated by Google. Google may generally unilaterally update its policies and guidelines without advance notice, which could in turn require modifications to, or prohibit and/or render obsolete certain of our products, services and/or business practices, which could be costly to address or otherwise have an adverse effect on our business, financial condition and results of operations. For the three months endedMarch 31, 2017 and 2016, revenue earned from Google was $187.8 million and $284.6 million, respectively. This revenue is earned by the businesses comprising the Applications and Publishing segments. For the three months endedMarch 31, 2017 and 2016, revenue earned from Google represents 84% and 70%; and 91% and 83%, of Applications and Publishing revenue, respectively. Accounts receivable related to revenue earned from Google totaled $65.5 million and $65.8 million at March 31, 2017 and December 31, 2016, respectively.

Recent Accounting Pronouncements

Accounting Pronouncements not yet adopted by the Company

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers, which clarifies the principles for recognizing revenue and develops a common standard for all industries. ASU 2014-09 was subsequently amended during 2015 and 2016; these amendments provide further revenue recognition guidance related to principal versus agent considerations, performance obligations and licensing, and narrow-scope improvements and practical expedients.

ASU No. 2014-09 is a comprehensive revenue recognition standard that will supersede nearly all existing revenue recognition guidance under GAAP. The new standard provides a single principles-based, five-step model to be applied to all contracts with customers. This five-step model includes (1) identifying the contract(s) with the customer, (2) identifying the performance obligations in the contract, (3) determining the transaction price, (4) allocating the transaction price to the performance obligations in the contract and (5) recognizing revenue when each performance obligation is satisfied. More specifically, revenue will be recognized when promised goods or services are transferred to the customer in an amount that reflects the consideration expected in exchange for those goods or services. ASU No. 2014-09 is effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption permitted for interim and annual reporting periods beginning after December 15, 2016. Upon adoption, ASU No. 2014-09 may either be applied retrospectively to each prior period presented or using the modified retrospective approach with the cumulative effect recognized as of the date of initial application.

While the Company’s evaluation of the impact the adoption of ASU No. 2014-09 on its consolidated financial statements continues, it has progressed to the point where we have reached certain preliminary determinations. The Company does not expect the adoption of ASU No. 2014-09 to have a material effect on its consolidated financial statements. The Company will adopt ASU No. 2014-09 using the modified retrospective approach effective January 1, 2018. Therefore, the cumulative effect of adoption will be reflected as an adjustment to beginning retained earnings in the Form 10-Q for the period ending March 31, 2018. The adoption of ASU No. 2014-09 will primarily affect the Company’s HomeAdvisor and Applications segments. The effect on HomeAdvisor will be that sales commissions, which represent the incremental direct costs of obtaining a service professional contract, will be capitalized and amortized over the average life of a service professional. These costs are expensed as incurred today. Within Applications, the primary effect will be to accelerate the recognition of the portion of the revenue of certain desktop applications sold by SlimWare that qualify as functional intellectual property under ASU No. 2014-09. This revenue is currently deferred and recognized over the applicable subscription term.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which supersedes existing guidance on accounting for leases in "Leases (Topic 840)" and generally requires all leases to be recognized in the statement of financial position. The provisions of ASU No. 2016-02 are effective for reporting periods beginning after December 15, 2018; early adoption is permitted. The provisions of ASU No. 2016-02 are to be applied using a modified retrospective approach. The Company is currently evaluating the impact the adoption of this standard update will have on its consolidated financial statements.

Accounting Pronouncements adopted by the Company

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which clarifies how cash receipts and cash payments in certain transactions are presented and classified on the statement of cash flows. The provisions of ASU No. 2016-15 are effective for reporting periods beginning after December 15, 2017, including interim periods, and will require adoption on a retrospective basis unless it is impracticable to apply, in which case we would be required to apply the amendments prospectively as of the earliest date practicable; early adoption is permitted. Upon adoption, cash payments not made soon after the acquisition date of a business combination to settle a contingent consideration liability are separated and classified as cash outflows for operating activities and financing activities. Cash payments up to the amount of the contingent consideration liability recognized at the acquisition date (including measurement-period adjustments) are classified as financing activities; any excess is classified as operating activities. Cash payments made soon after the acquisition date of a business combination by an acquirer to settle a contingent consideration liability are classified as cash outflows for investing activities. The Company early adopted the provisions of ASU No. 2016-15 on January 1, 2017. As a result of the adoption of ASU No. 2016-15, $11.1 million of acquisition-related contingent consideration payments for the three months ended March 31, 2017 was in excess of the liability recognized at the acquisition date and, therefore, has been classified as a cash outflow in "Other adjustments, net" within net cash provided by operating activities in the accompanying consolidated statement of cash flows.

In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The Company adopted the provisions of ASU No. 2016-09 on January 1, 2017. Excess tax benefits or deficiencies related to equity awards to employees upon exercise of stock options and the vesting of restricted stock units after January 1, 2017 are (i) reflected in the consolidated statement of operations as a component of the provision for income taxes, rather than recognized in equity, and (ii) reflected as operating, rather than financing, cash flows in our consolidated statement of cash flows. Excess tax benefits for the three months ended March 31, 2017 were $26.8 million. Excess tax benefits of $15.3 million for the three months ended March 31, 2016 were reclassified in the consolidated statement of cash flows to conform to the current year presentation. Upon adoption, the calculation of fully diluted shares excludes excess tax benefits from the assumed proceeds in applying the treasury stock method, they previously were included in the calculation; this change increased fully diluted shares by approximately 1.3 million shares for the three months ended March 31, 2017. The Company continues to account for forfeitures using an estimated forfeiture rate.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which is intended to simplify the accounting for goodwill impairment. The guidance eliminates the requirement to calculate the implied fair value of goodwill under today’s two-step impairment test to measure a goodwill impairment charge. The provisions of ASU No. 2017-04 are effective for reporting periods beginning after December 15, 2019; early adoption is permitted. The provisions of ASU No. 2017-04 are to be applied using a prospective approach. The Company early adopted the provisions of ASU No. 2017-04 on January 1, 2017 and the adoption of this standard update did not have a material impact on its consolidated financial statements.

NOTE 2—INCOME TAXES

At the end of each interim period, the Company makes its best estimate of the annual expected effective income tax rate and applies that rate to its ordinary year-to-date earnings or loss. The income tax provision or benefit related to significant, unusual, or extraordinary items, if applicable, that will be separately reported or reported net of their related tax effects are

individually computed and recognized in the interim period in which they occur. In addition, the effect of changes in enacted tax laws or rates, tax status, judgment on the realizability of a beginning-of-the-year deferred tax asset in future years or the liabilities for uncertain tax positions is recognized in the interim period in which the change occurs.

The computation of the annual expected effective income tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected pre-tax income (or loss) for the year, projections of the proportion of income (and/or loss) earned and taxed in foreign jurisdictions, permanent and temporary differences, and the likelihood of the realization of deferred tax assets generated in the current year. The accounting estimates used to compute the provision or benefit for income taxes may change as new events occur, more experience is acquired, additional information is obtained or our tax environment changes. To the extent that the expected annual effective income tax rate changes during a quarter, the effect of the change on prior quarters is included in income tax provision in the quarter in which the change occurs.

For the three months endedMarch 31, 2017, the Company recorded an income tax benefit of $23.9 million. The income tax benefit for the three months endedMarch 31, 2017 is due primarily to the effect of adopting the provisions of ASU No. 2016-09 on January 1, 2017. Under ASU No. 2016-09, excess tax benefits generated by the settlement or exercise of stock-based awards of $26.8 million are recognized as a reduction to the income tax provision rather than additional paid-in capital. For the three months ended March 31, 2016, the Company recorded an income tax provision of $1.5 million which represents an effective income tax rate of 16%. The effective tax rate for the three months ended March 31, 2016 is lower than the statutory rate of 35% due primarily to the non-taxable gain on the sale of PriceRunner, partially offset by the non-deductible loss on contingent consideration fair value adjustments and the unbenefited loss associated with the other-than-temporary impairment charges related to certain of the Company's cost method investments.

The Company recognizes interest and, if applicable, penalties related to unrecognized tax benefits in the income tax provision. At March 31, 2017 and December 31, 2016, the Company has accrued $2.7 million and $2.6 million, respectively, for the payment of interest. At March 31, 2017 and December 31, 2016, the Company has accrued $1.6 million and $1.7 million, respectively, for penalties.

The Company is routinely under audit by federal, state, local and foreign authorities in the area of income tax. These audits include questioning the timing and the amount of income and deductions and the allocation of income and deductions among various tax jurisdictions. The Internal Revenue Service is currently auditing the Company’s federal income tax returns for the years ended December 31, 2010 through 2012. The statute of limitations for the years 2010 through 2012 has been extended to December 31, 2017. Various other jurisdictions are open to examination for tax years beginning with 2009. Income taxes payable include reserves considered sufficient to pay assessments that may result from examination of prior year tax returns. Changes to reserves from period to period and differences between amounts paid, if any, upon resolution of audits and amounts previously provided may be material. Differences between the reserves for income tax contingencies and the amounts owed by the Company are recorded in the period they become known.

At March 31, 2017 and December 31, 2016, unrecognized tax benefits, including interest and penalties, are $40.1 million and $41.0 million, respectively. If unrecognized tax benefits at March 31, 2017 are subsequently recognized, $36.9 million, net of related deferred tax assets and interest, would reduce income tax expense. The comparable amount as of December 31, 2016 was $37.7 million. The Company believes that it is reasonably possible that its unrecognized tax benefits could decrease by $11.8 million by March 31, 2018, due to expirations of statutes of limitations and settlements; $11.1 million of which would reduce the income tax provision.

The contractual maturities of debt securities classified as available-for-sale at March 31, 2017 are due within one year.

The aggregate fair value of available-for-sale marketable debt securities in an unrealized loss position is $12.0 million as of March 31, 2017. There are no investments in available-for-sale marketable debt securities that have been in a continuous unrealized loss position for longer than twelve months as of March 31, 2017. The gross unrealized losses on the marketable debt securities relate primarily to changes in interest rates. The Company does not consider the gross unrealized losses to be other-than-temporary because the Company does not intend to sell the marketable debt securities that generated the gross unrealized losses at March 31, 2017, and it is not more likely than not that the Company will be required to sell these securities before recovery of their amortized costs bases, which may be maturity.

At December 31, 2016, available-for-sale marketable securities are as follows:

NOTE 4—FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS

The Company categorizes its financial instruments measured at fair value into a fair value hierarchy that prioritizes the inputs used in pricing the asset or liability. The three levels of the fair value hierarchy are:

• Level 1: Observable inputs obtained from independent sources, such as quoted prices for identical assets and liabilities in active markets.

• Level 2: Other inputs, which are observable directly or indirectly, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and inputs that are derived principally from or corroborated by observable market data. The fair values of the Company's Level 2 financial assets are primarily obtained from observable market prices for identical underlying securities that may not be actively traded. Certain of these securities may have different market prices from multiple market data sources, in which case an average market price is used.

• Level 3: Unobservable inputs for which there is little or no market data and require the Company to develop its own assumptions, based on the best information available in the circumstances, about the assumptions market participants would use in pricing the assets or liabilities. See below for a discussion of fair value measurements made using Level 3 inputs.

The following tables present the Company's financial instruments that are measured at fair value on a recurring basis:

Contingent Consideration Arrangements

As of March 31, 2017, there are five contingent consideration arrangements related to business acquisitions. The maximum contingent payments related to these five arrangements are $121.1 million and the fair value of these arrangements at March 31, 2017 is $21.8 million.

The contingent consideration arrangements are generally based upon earnings performance and/or operating metrics. The Company determines the fair value of the contingent consideration arrangements by using probability-weighted analyses to

14

IAC/INTERACTIVECORP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

determine the amounts of the gross liability, and, if the arrangement is long-term in nature, applying a discount rate that appropriately captures the risks associated with the obligation to determine the net amount reflected in the consolidated financial statements. The number of scenarios in the probability-weighted analyses can vary; generally, more scenarios are prepared for longer duration and more complex arrangements. The fair values of the contingent consideration arrangements at both March 31, 2017 and December 31, 2016 reflect discount rates of 12%.

The fair values of the contingent consideration arrangements are sensitive to changes in the forecasts of earnings and/or the relevant operating metrics and changes in discount rates. The Company remeasures the fair value of the contingent consideration arrangements each reporting period, including the accretion of the discount, if applicable, and changes are recognized in “General and administrative expense” in the accompanying consolidated statement of operations. The contingent consideration arrangement liability at March 31, 2017 and December 31, 2016 includes a current portion of $21.4 million and $33.4 million, respectively, and non-current portion of $0.5 million and $0.4 million, respectively, which are included in “Accrued expenses and other current liabilities” and “Other long-term liabilities,” respectively, in the accompanying consolidated balance sheet.

Assets measured at fair value on a nonrecurring basis

The Company's non-financial assets, such as goodwill, intangible assets and property and equipment, as well as equity and cost method investments, are adjusted to fair value only when an impairment charge is recognized. Such fair value measurements are based predominantly on Level 3 inputs.

Cost method investments

At March 31, 2017 and December 31, 2016, the carrying values of the Company's investments accounted for under the cost method totaled $112.7 million and $116.1 million, respectively, and are included in "Long-term investments" in the accompanying consolidated balance sheet. The Company evaluates each cost method investment for impairment on a quarterly basis and recognizes an impairment loss if a decline in value is determined to be other-than-temporary. If the Company has not identified events or changes in circumstances that may have a significant adverse effect on the fair value of a cost method investment, then the fair value of such cost method investment is not estimated, as it is impracticable to do so.

Financial instruments measured at fair value only for disclosure purposes

The following table presents the carrying value and the fair value of financial instruments measured at fair value only for disclosure purposes:

	March 31, 2017						December 31, 2016
	Carrying Value			Fair Value			Carrying Value			Fair Value

Match Group Senior Notes:

The 2016 Match Group Senior Notes were issued on June 1, 2016. The proceeds of $400 million were used to prepay a portion of indebtedness outstanding under the Match Group Term Loan. At any time prior to June 1, 2019, these notes may be redeemed at a redemption price equal to the sum of the principal amount thereof, plus accrued and unpaid interest and a make-whole premium. Thereafter, these notes may be redeemed at redemption prices set forth in the indenture governing the notes, together with accrued and unpaid interest thereon to the applicable redemption date.

The 2015 Match Group Senior Notes were issued on November 16, 2015, in exchange for a portion of the IAC 2012 Senior Notes (the "Match Exchange Offer"). At any time prior to December 15, 2017, the 2015 Match Group Senior Notes may be redeemed at a redemption price equal to the sum of the principal amount thereof, plus accrued and unpaid interest and a make-whole premium. Thereafter, these notes may be redeemed at redemption prices set forth in the indenture governing the notes, together with accrued and unpaid interest thereon to the applicable redemption date.

The indentures governing the 2016 and 2015 Match Group Senior Notes contain covenants that would limit Match Group's ability to pay dividends or to make distributions and repurchase or redeem Match Group stock in the event a default has occurred or Match Group's leverage ratio (as defined in the indentures) exceeds 5.0 to 1.0. At March 31, 2017 there were no limitations pursuant thereto. There are additional covenants that limit Match Group's ability and the ability of its subsidiaries to, among other things, (i) incur indebtedness, make investments, or sell assets in the event Match Group is not in compliance with the leverage ratio set forth in the indenture, and (ii) incur liens, enter into agreements restricting Match Group subsidiaries' ability to pay dividends, enter into transactions with affiliates and consolidate, merge or sell substantially all of their assets.

Match Group Term Loan and Match Group Credit Facility:

On November 16, 2015, under a credit agreement (the "Match Group Credit Agreement"), Match Group borrowed $800 million in the form of a term loan (the "Match Group Term Loan"). On March 31, 2016, Match Group made a $10 million principal payment on the Match Group Term Loan. On June 1, 2016, the $400 million in proceeds from the 2016 Match Group Senior Notes, described above, were used to prepay a portion of the Match Group Term Loan. On December 8, 2016, Match Group made an additional $40 million principal payment on the Match Group Term Loan and the remaining outstanding balance of $350 million, which is due at maturity, was repriced. The Match Group Term Loan provides for additional annual principal payments as part of an excess cash flow sweep provision, the amount of which, if any, is governed by the secured net leverage ratio contained in the Match Group Credit Agreement. The Match Group Term Loan bears interest, at Match Group's option, at a base rate or LIBOR, plus 2.25% or 3.25%, respectively, and in the case of LIBOR, a floor of 0.75%. The interest rate on the Match Group Term Loan at March 31, 2017 is 4.10%. Interest payments are due at least semi-annually through the term of the loan.

Match Group has a $500 million revolving credit facility (the "Match Group Credit Facility") that expires on October 7, 2020. At March 31, 2017 and December 31, 2016, there were no outstanding borrowings under the Match Group Credit Facility. The annual commitment fee on undrawn funds based on the current leverage ratio is 30 basis points. Borrowings under the Match Group Credit Facility bear interest, at Match Group's option, at a base rate or LIBOR, in each case plus an applicable margin, which is determined by reference to a pricing grid based on Match Group's consolidated net leverage ratio. The terms of the Match Group Credit Facility require Match Group to maintain a consolidated net leverage ratio of not more than 5.0 to 1.0 and a minimum interest coverage ratio of not less than 2.5 to 1.0 (in each case as defined in the agreement).

There are additional covenants under the Match Group Credit Facility and the Match Group Term Loan that limit the ability of Match Group and its subsidiaries to, among other things, incur indebtedness, pay dividends or make distributions. While the Match Group Term Loan remains outstanding, these same covenants under the Match Group Credit Agreement are more restrictive than the covenants that are applicable to the Match Group Credit Facility. Obligations under the Match Group Credit Facility and Match Group Term Loan are unconditionally guaranteed by certain Match Group wholly-owned domestic subsidiaries, and are also secured by the stock of certain Match Group domestic and foreign subsidiaries. The Match Group Term Loan and outstanding borrowings, if any, under the Match Group Credit Facility rank equally with each other, and have priority over the 2016 and 2015 Match Group Senior Notes to the extent of the value of the assets securing the borrowings under the Match Group Credit Agreement.

IAC Senior Notes:

The 2013 and 2012 Senior Notes were issued by IAC on November 15, 2013 and December 21, 2012, respectively. The 2013 and 2012 Senior Notes are unconditionally guaranteed by certain wholly-owned domestic subsidiaries, which are designated as guarantor subsidiaries, except neither Match Group nor any of its subsidiaries guarantee any debt of IAC, or are subject to any of the covenants related to such debt. The guarantor subsidiaries are the same for the 2013 and 2012 Senior Notes. See "Note 11—Guarantor and Non-guarantor Financial Information" for financial information relating to guarantor and non-guarantor.

For the three months ended March 31, 2017, the Company redeemed and repurchased $23.3 million of its 2013 Senior Notes and called an additional $5.0 million for redemption, and repurchased $3.3 million of its 2012 Senior Notes. For the three months ended March 31, 2016, the Company redeemed and repurchased $30.0 million of its 2013 Senior Notes and repurchased $2.9 million of its 2012 Senior Notes.

The indenture governing the 2013 Senior Notes contains covenants that would limit our ability to pay dividends or to make distributions and repurchase or redeem our stock in the event a default has occurred or our leverage ratio (as defined in the indenture) exceeds 3.0 to 1.0. At March 31, 2017, there were no limitations pursuant thereto. There are additional covenants that limit the Company's ability and the ability of its restricted subsidiaries to, among other things, (i) incur indebtedness, make investments, or sell assets in the event we are not in compliance with the financial ratio set forth in the indenture, and (ii) incur liens, enter into agreements limiting our restricted subsidiaries' ability to pay dividends, enter into transactions with affiliates and consolidate, merge or sell substantially all of our assets. The indenture governing the 2012 Senior Notes was amended to eliminate substantially all of the restrictive covenants contained therein in connection with the Match Exchange Offer.

IAC Credit Facility:

IAC has a $300.0 million revolving credit facility (the "IAC Credit Facility") that expires October 7, 2020. At March 31, 2017 and December 31, 2016, there were no outstanding borrowings under the IAC Credit Facility. The annual commitment fee on undrawn funds is currently 35 basis points, and is based on the leverage ratio most recently reported. Borrowings under the IAC Credit Facility bear interest, at the Company's option, at a base rate or LIBOR, in each case, plus an applicable margin, which is determined by reference to a pricing grid based on the Company's leverage ratio. The terms of the IAC Credit Facility require that the Company maintains a leverage ratio (as defined in the agreement) of not more than 3.25 to 1.0 and restrict our ability to incur additional indebtedness. Borrowings under the IAC Credit Facility are unconditionally guaranteed by the same domestic subsidiaries that guarantee the 2013 and 2012 Senior Notes and are also secured by the stock of certain of our domestic and foreign subsidiaries. The 2013 and 2012 Senior Notes rank equally with each other, and are subordinate to outstanding borrowings under the IAC Credit Facility to extent of the value of the assets securing such borrowings.

^(a)  Represents the impact on earnings related to Match Group's dilutive securities under the if-converted method.

^(b)  If the effect is dilutive, weighted average common shares outstanding include the incremental shares that would be issued upon the assumed exercise of subsidiary denominated equity, stock options and vesting of restricted stock units ("RSUs"). For the three months endedMarch 31, 2017 and 2016, 2.0 million and 3.9 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive.

^(c)  Market-based awards and performance-based stock units (“PSUs”) are considered contingently issuable shares. Market-based awards and PSUs are included in the denominator for earnings per share if (i) the applicable market or performance condition(s) has been met and (ii) the inclusion of the market-based awards and PSUs are dilutive for the respective reporting periods. For the three months endedMarch 31, 2017 and 2016, 0.4 million and 1.0 million market-based awards and PSUs, respectively, were excluded from the calculation of diluted earnings per share because the market or performance conditions had not been met.

NOTE 8—SEGMENT INFORMATION

The overall concept that IAC employs in determining its operating segments is to present the financial information in a manner consistent with: how the chief operating decision maker views the businesses; how the businesses are organized as to segment management; and the focus of the businesses with regards to the types of services or products offered or the target market. Operating segments are combined for reporting purposes if they meet certain aggregation criteria, which principally relate to the similarity of their economic characteristics or, in the case of the Other reportable segment, do not meet the quantitative thresholds that require presentation as separate operating segments.

________________________

^(a)  The Company's primary financial measure is Adjusted EBITDA, which is defined as operating income excluding: (1) stock-based compensation expense; (2) depreciation; and (3) acquisition-related items consisting of (i) amortization of intangible assets and impairments of goodwill and intangible assets, if applicable, and (ii) gains and losses recognized on changes in the fair value of contingent consideration arrangements. The Company believes this measure is useful for analysts and investors as this measure allows a more meaningful comparison between our performance and that of our competitors. Moreover, our management uses this measure internally to evaluate the performance of our business as a whole and our individual business segments, and this measure is one of the primary metrics by which our internal budgets are based and by which management is compensated. The above items are excluded from our Adjusted EBITDA measure because these items are non-cash in nature, and we believe that by excluding these items, Adjusted EBITDA corresponds more closely to the cash operating income generated from our business, from which capital investments are made and debt is serviced. Adjusted EBITDA has certain limitations in that it does not take into account the impact to IAC's statement of operations of certain expenses.

NOTE 10—CONTINGENCIES

In the ordinary course of business, the Company is a party to various lawsuits. The Company establishes reserves for specific legal matters when it determines that the likelihood of an unfavorable outcome is probable and the loss is reasonably estimable. Management has also identified certain other legal matters where we believe an unfavorable outcome is not probable and, therefore, no reserve is established. Although management currently believes that resolving claims against us, including claims where an unfavorable outcome is reasonably possible, will not have a material impact on the liquidity, results of operations, or financial condition of the Company, these matters are subject to inherent uncertainties and management's view of these matters may change in the future. The Company also evaluates other contingent matters, including income and non-income tax contingencies, to assess the likelihood of an unfavorable outcome and estimated extent of potential loss. It is possible that an unfavorable outcome of one or more of these lawsuits or other contingencies could have a material impact on the liquidity, results of operations, or financial condition of the Company. See "Note 2—Income Taxes" for additional information related to income tax contingencies.

NOTE 11—GUARANTOR AND NON-GUARANTOR FINANCIAL INFORMATION

The 2013 and 2012 Senior Notes are unconditionally guaranteed, jointly and severally, by certain domestic subsidiaries which are 100% owned by the Company. The following tables present condensed consolidating financial information at March 31, 2017 and December 31, 2016 and for the three months endedMarch 31, 2017 and 2016 for: IAC, on a stand-alone basis; the combined guarantor subsidiaries of IAC; the combined non-guarantor subsidiaries of IAC; and IAC on a consolidated basis.

• International - consists of the financial results and metrics for customers located outside of the United States and Canada.

• Direct Revenue - is revenue that is directly received from an end user of its products.

• Average PMC - is calculated by summing the number of paid members, or paid member count ("PMC"), at the end of each day in the relevant measurement period and dividing it by the number of calendar days in that period. PMC as of any given time represents the number of users with a paid membership at that time.

• Average Revenue per Paying User ("ARPPU") - is Direct Revenue from paid members in the relevant measurement period (whether in the form of subscription payments or àla carte payments) divided by the Average PMC in such period divided by the number of calendar days in such period.

Video

• Vimeo ending subscribers - are the number of subscribers to Vimeo's Creator Platform with a Plus, Pro or Business subscription at the end of the period.

Operating costs and expenses:

• Cost of revenue - consists primarily of traffic acquisition costs and includes (i) payments made to partners who distribute our Partnerships customized browser-based applications and who integrate our paid listings into their websites and (ii) fees paid to Apple and Google related to the distribution and the facilitation of in-app purchases of product features. These payments include amounts based on revenue share and other arrangements. Cost of revenue also includes production costs related to media produced by Electus and other businesses within our Video segment and expenses associated with the operation of the Company's data centers, consisting of compensation (including stock-based compensation) and other employee-related costs, hosting fees, credit card processing fees, content acquisition costs and rent. Cost of revenue in 2016 includes ShoeBuy's cost of products sold and shipping and handling costs.

• Selling and marketing expense - consists primarily of advertising expenditures and compensation (including stock-based compensation) and other employee-related costs for personnel engaged in selling and marketing, sales support and customer service functions. Advertising expenditures include online marketing, including fees paid to search engines and third parties that distribute our Consumer downloadable desktop applications, offline marketing, which is primarily television advertising, and partner-related payments to those who direct traffic to the Match Group brands.

• General and administrative expense - consists primarily of compensation (including stock-based compensation) and other employee-related costs for personnel engaged in executive management, finance, legal, tax and human resources, acquisition-related contingent consideration fair value adjustments (described below), fees for professional services and facilities costs.

• Product development expense -consists primarily of compensation (including stock-based compensation) and other employee-related costs that are not capitalized for personnel engaged in the design, development, testing and enhancement of product offerings and related technology.

• Acquisition-related contingent consideration fair value adjustments - relate to the portion of the purchase price (of certain acquisitions) that is contingent upon the future operating performance of the acquired company.  The amounts ultimately paid are generally dependent upon earnings performance and/or operating metrics as stipulated in the relevant purchase agreements.  The fair value of the liability is estimated at the date of acquisition and adjusted each reporting period until the liability is settled.  If the payment date of the liability is longer than one year, the amount is initially recorded net of a discount, which is amortized as an expense each period.  In a period where the acquired company is expected to perform better than the previous estimate, the liability will be increased resulting in additional expense; and in a period when the acquired company is expected to perform worse than the previous estimate, the liability will be decreased resulting in income.  The year-over-year impact can be significant, for example, if there is income in one period and expense in the other period.

Long-term debt:

• 2012 Senior Notes - IAC's 4.75% Senior Notes due December 15, 2022, with interest payable each June 15 and December 15, which commenced June 15, 2013, a portion of which were exchanged for the 2015 Match Group Senior Notes (described below) on November 16, 2015.

Management Overview

IAC is a leading media and Internet company comprised of widely known consumer brands, such as HomeAdvisor, Vimeo, Dotdash (formerly About.com), Dictionary.com, The Daily Beast, Investopedia, and Match Group's online dating portfolio, which includes Match, Tinder, PlentyOfFish and OkCupid.

For a more detailed description of the Company's operating businesses, see the Company's Annual Report on Form 10-K for the year ended December 31, 2016.

A significant portion of the revenue from our Applications and Publishing segments is derived from online advertising, most of which is attributable to our services agreement with Google Inc. ("Google"). The Company's services agreement became effective on April 1, 2016, following the expiration of the previous services agreement. The services agreement expires on March 31, 2020; however, the Company may choose to terminate the agreement effective March 31, 2019. The terms of the new Google services agreement significantly reduced the revenue earned by our Publishing segment during the twelve months ended March 31, 2017 compared to the twelve months ended March 31, 2016. Given the new services agreement with Google has been in place for a full year as of April 1, 2017, the Company does not expect the Publishing segment's year-over-year revenue to be negatively affected by the new services agreement for the balance of 2017. However, the services agreement requires that we comply with certain guidelines promulgated by Google, and Google may generally unilaterally update its policies and guidelines without advance notice. Any such updates could in turn require modifications to, or prohibit and/or render obsolete certain of our products, services and/or business practices, which could be costly to address or otherwise have an adverse effect on our business, financial condition and results of operations. For the three months endedMarch 31, 2017 and 2016, revenue earned from Google was $187.8 million and $284.6 million, respectively. The decline in Google revenue in the first quarter of 2017 was primarily due to the effects of the new contract. For the three months endedMarch 31, 2017 and 2016, revenue earned from Google represents 84% and 70%; and 91% and 83%, of Applications and Publishing revenue, respectively.

2017 Developments

During the three months endedMarch 31, 2017, the Company repurchased 0.7 million shares of common stock at an average price of $69.73 per share, or $50.1 million in aggregate.

During the three months endedMarch 31, 2017, the Company redeemed and repurchased $23.3 million of its 2013 Senior Notes and called an additional $5.0 million for redemption, and repurchased $3.3 million of its 2012 Senior Notes.

On May 1, 2017, the Company announced that it has entered into a definitive agreement to combine IAC’s HomeAdvisor and Angie’s List into a new, publicly traded company, to be called ANGI Homeservices Inc. IAC will own between approximately 87 % and 90% of the new company at closing, which is expected to take place in the fourth quarter of 2017.

33

On March 31, 2017, Match Group sold its non-dating business, consisting of The Princeton Review. The non-dating business does not meet the threshold to be reflected as a discontinued operation at the IAC level. The Company has moved the non-dating business to its “Other” segment as of and for the quarter ended March 31, 2017 and prior period segment data has been recast to conform to the current period presentation.

HomeAdvisor acquired MyBuilder on March 24, 2017, and HomeStars on February 8, 2017, leading home services platforms in the United Kingdom and Canada, respectively.

First Quarter 2017 Consolidated Results

For the three months endedMarch 31, 2017, the Company's revenue decreased $58.3 million, or 7%, however, operating income and Adjusted EBITDA grew $15.6 million, or 73%, and $16.1 million, or 19%, respectively. Despite strong growth of $39.3 million from HomeAdvisor and $38.4 million from Match Group, revenue decreased due primarily to a significant decline of $87.9 million from Publishing primarily due to the effects of the new Google contract and a decline of $42.5 million from Other due primarily to the sales of ShoeBuy and PriceRunner on December 30, 2016 and March 18, 2016, respectively. Operating income increased $15.6 million primarily due to the increase of $16.1 million in Adjusted EBITDA. The Adjusted EBITDA increase was primarily driven by strong growth of $19.0 million from Match Group, $6.1 million from HomeAdvisor, $3.9 from Applications and reduced losses of $2.2 million from Video, partially offset by a decline of $10.2 million from Publishing and lower expenses of $4.9 million in the prior year from Corporate.

Results of Operations for the three months ended March 31, 2017 compared to the three months ended March 31, 2016

Total	$	760,833		$	(58,346	)	(7	)%	$	819,179

Match Group revenue increased 15% driven by International Direct Revenue growth of $25.7 million, or 30%, and North America Direct Revenue growth of $13.0 million, or 8%. Both International and North America Direct Revenue were driven by higher Average PMC, up 33% and 7%, respectively, due primarily to continued growth in paying members at Tinder, PlentyOfFish and Pairs (in Japan). International Direct Revenue growth was partially offset by a 2% decline in ARPPU. The decline in ARPPU was due to continued mix shift towards brands with lower price points. North America ARPPU grew 2% driven by higher rates, partially offset by continued mix shift towards brands with lower price points.

HomeAdvisor revenue increased 35% driven by strong growth of $36.0 million, or 38%, at the Domestic business and 35% at the European business. Domestic business revenue growth was driven by a 34% increase in Paying SPs to 156,000 and a 34% increase in Service Requests to 3.7 million. Revenue growth at the European business was driven by the acquisition of a controlling interest in MyHammer Holding AG on November 3, 2016 and organic growth across other regions.

Video revenue decreased 8% driven by Electus due primarily to the timing of projects, partially offset by accelerating growth at Vimeo, which had ending subscribers of 0.8 million, an increase of 15%, compared to the prior year.

Applications revenue decreased less than 1% due to a decline of $13.5 million, or 32%, in Partnerships, largely offset by an increase of $12.6 million, or 11%, in Consumer. Partnerships revenue decreased due primarily to the loss of certain partners. The growth in Consumer was driven by a 164% increase at Apalon and strong growth at SlimWare.

34

Publishing revenue decreased 53% due to $46.1 million, or 56%, lower Premium Brands revenue and $41.8 million, or 50%, lower Ask & Other revenue. Premium Brands revenue decreased due primarily to declines in paid search traffic, mainly attributable to the new Google contract, which became effective April 1, 2016, partially offset by double digit revenue growth at Investopedia. Ask & Other revenue decreased due to a decline in revenue at Ask.com primarily as a result of the new Google contract as well as declines in revenue at certain other legacy businesses.

Other revenue decreased 64% due principally to the sales of ShoeBuy and PriceRunner on December 30, 2016 and March 18, 2016, respectively.

Cost of revenue

	Three Months Ended March 31,
	2017	$ Change	% Change	2016
	(Dollars in thousands)
Cost of revenue (exclusive of depreciation shown separately below)	$145,958	$(47,776)	(25)%	$193,734
As a percentage of revenue	19%			24%

Cost of revenue in 2017 decreased from 2016 due to decreases of $30.7 million from Other, $20.9 million from Publishing, $6.1 million from Applications and $5.8 million from Video, partially offset by an increase of $15.1 million from Match Group.

• The Other decrease was due primarily to the sale of ShoeBuy in December 2016.

• The Publishing decrease was due primarily to reductions of $16.4 million in traffic acquisition costs driven by a decline in revenue at Ask.com and certain legacy businesses and $2.2 million in content costs due primarily to About.com due, in part, to its vertical brand strategy, which launched in the second quarter of 2016.

• The Applications decrease was due primarily to a reduction of $3.6 million in traffic acquisition costs driven by a decline in revenue at Partnerships and a decrease of $1.0 million in compensation due, in part, to a decrease in headcount as a result of reductions in workforce in 2016.

• The Video decrease was due primarily to a net decrease of $5.4 million in production costs at our media and video businesses.

• The Match Group increase was due primarily to a significant increase of $13.5 million in in-app purchase fees across multiple brands primarily at Tinder.

Selling and marketing expense

	Three Months Ended March 31,

Selling and marketing expense	$350,411	$(32,653)	(9)%	$383,064
As a percentage of revenue	46%			47%

Selling and marketing expense in 2017 decreased from 2016 due to a decrease of $50.0 million from Publishing, partially offset by an increase of $21.3 million from HomeAdvisor.

• The Publishing decrease was due primarily to a reduction of $45.7 million in online marketing, mostly resulting from changes in the new Google contract, which became effective April 1, 2016, and other Google policy and algorithm updates, and a decrease of $3.3 million in compensation due, in part, to reductions in workforce that occurred in 2016.

• The HomeAdvisor increase was due primarily to higher online and offline marketing of $14.4 million and an increase of $6.4 million in compensation due primarily to an increase in the sales force at the Domestic business.

35

General and administrative expense

	Three Months Ended March 31,

As a percentage of revenue	19%			16%

General and administrative expense in 2017 increased from 2016 due to increases of $10.9 million from HomeAdvisor, $6.6 million from Corporate and $4.9 million from Match Group, partially offset by decreases of $9.6 million from Other and $3.8 million from Publishing.

• The HomeAdvisor increase was due primarily to higher compensation of $2.2 million due, in part, to increased headcount at the Domestic business, an increase of $2.7 million in bad debt expense due, in part, to higher revenue at the Domestic business, $1.8 million from recent acquisitions, and $1.0 million in transaction-related costs in the current year period.

• The Corporate increase was due primarily to lower compensation costs in 2016, including bonus expense and severance costs.

• The Match Group increase was due primarily to an increase of $3.6 million in compensation, partially offset by a decrease in expense of $1.8 million in acquisition-related contingent consideration fair value adjustments. The increase in compensation is due to an increase of $2.7 million in stock-based compensation expense primarily due to an increase in expense related to a subsidiary denominated equity award issued to a non-employee and an increase in headcount from business growth.

• The Other decrease was due primarily to the sales of ShoeBuy and PriceRunner in 2016.

• The Publishing decrease was due primarily to the sale of ASKfm in 2016, a decrease of $1.1 million in professional fees at Ask.com and reductions in workforce in 2016.

Product development expense

As a percentage of revenue	7%			7%

Product development expense in 2017 decreased from 2016 due to decreases of $3.0 million from Publishing and $2.2 million from Applications.

• The Publishing decrease was due primarily to a decrease of $1.1 million from the sale of ASKfm in 2016 and lower compensation of $0.7 million due, in part, to reductions in workforce in 2016.

• The Applications decrease was due primarily to a decrease of $1.9 million in compensation due, in part, to a decrease in headcount related to reductions in workforce in 2016.

Depreciation	$19,888	$4,093	26%	$15,795

________________________

NM = not meaningful

Operating income in 2017 increased from 2016 due primarily to an increase of $16.1 million in Adjusted EBITDA described below, a decrease of $4.7 million in amortization of intangibles and a change of $1.8 million in acquisition-related contingent consideration fair value adjustments, partially offset by increases of $4.1 million in depreciation expense and $2.8 million in stock-based compensation expense. The decrease in amortization of intangibles is due primarily to certain intangible assets from the PlentyOfFish acquisition becoming fully amortized. The increase in stock-based compensation expense is due primarily to the issuance of new equity awards since 2016 and an increase in expense related to a subsidiary denominated equity award issued to a non-employee, partially offset by a net decrease in expense associated with the modification of certain equity awards.

At March 31, 2017, there was $278.5 million of unrecognized compensation cost, net of estimated forfeitures, related to all equity-based awards, which is expected to be recognized over a weighted average period of approximately 3.0 years.

For a reconciliation of operating income (loss) for the Company's reportable segments and net earnings attributable to IAC's shareholders to Adjusted EBITDA, see "Note 8—Segment Information" to the consolidated financial statements included in "Item 1—Consolidated Financial Statements."

Match Group Adjusted EBITDA increased 28% due primarily to an increase of $38.4 million in revenue and a decrease in selling and marketing expense as a percentage of revenue as the product mix continues to shift towards brands with lower marketing spend, partially offset by an increase in cost of revenue and general and administrative expense.

HomeAdvisor Adjusted EBITDA more than doubled to $11.1 million due primarily to an increase of $39.3 million in revenue. Adjusted EBITDA growth was reduced by higher losses at the European business, an increase in selling and marketing expense at both the Domestic and European businesses, $1.0 million in transaction-related costs and $0.5 million in transaction-related deferred revenue write-offs. Higher losses at the European business were primarily driven by our European expansion strategy including higher selling and marketing expense and higher compensation cost.

Video Adjusted EBITDA loss improved 13% due to reduced losses at Daily Burn and Vimeo, partially offset by Electus which incurred losses in the current year period versus a slight profit in 2016.

Applications Adjusted EBITDA increased 12% due primarily to lower operating costs resulting from restructurings in 2016, and improved profitability at Apalon and SlimWare, partially offset by $1.5 million in restructuring charges during the current year period.

Publishing Adjusted EBITDA decreased 90% due primarily to lower revenue driven by the new Google contract, partially offset by lower operating costs resulting from the restructurings in 2016.

Corporate Adjusted EBITDA loss increased 47% due primarily to lower compensation costs in 2016, including bonus expense and severance costs.

Interest expense decreased $3.1 million due primarily to lower interest expense of $7.5 million related to the 2016 prepayment and repricing of the Match Group Term Loan and a decrease of $1.6 million in interest expense related to lower outstanding balances of the 2013 and 2012 Senior Notes. Partially offsetting this decrease is $6.5 million of interest expense associated with the 2016 Match Group Senior Notes.

Other income, net in 2016includes a $13.5 million gain related to the sale of PriceRunner, $4.5 million in net foreign currency exchange gains, interest income of $1.6 million and $1.2 million in gains related to the sale of several long-term investments, partially offset by $2.3 million in other-than-temporary impairment charges related to certain cost method investments as a result of our assessment of the near-term prospects and financial condition of the investees, a $1.4 million loss on the 2013 and 2012 Senior Note redemptions and repurchases and a $1.2 million mark-to-market adjustment pertaining to a subsidiary denominated equity award issued to a non-employee.

The 2017 income tax benefit is due primarily to the effect of adopting the provisions of the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, on January 1, 2017. Under ASU No. 2016-09, excess tax benefits generated by the settlement or exercise of stock-based awards of $26.8 million in the first quarter of 2017 are recognized as a reduction to the income tax provision rather than additional paid-in capital.

The 2016 effective income tax rate was lower than the statutory rate of 35% due primarily to the non-taxable gain on the sale of PriceRunner, partially offset by the non-deductible loss on contingent consideration fair value adjustments and the unbenefited loss associated with the other-than-temporary impairment charges related to certain of the Company's cost method investments.

For further details of income tax matters, see "Note 2—Income Taxes" to the consolidated financial statements included in "Item 1—Consolidated Financial Statements."

Net (earnings) loss attributable to noncontrolling interests

Noncontrolling interests represent the noncontrolling holders’ percentage share of earnings or losses from the subsidiaries in which the Company holds a majority, but less than 100 percent, ownership interest and the results of which are included in our consolidated financial statements.

IAC'S PRINCIPLES OF FINANCIAL REPORTING

IAC reports Adjusted EBITDA as a supplemental measure to U.S. generally accepted accounting principles ("GAAP"). This measure is one of the primary metrics by which we evaluate the performance of our businesses, on which our internal budgets are based and by which management is compensated. We believe that investors should have access to, and we are obligated to provide, the same set of tools that we use in analyzing our results. This non-GAAP measure should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results. IAC endeavors to compensate for the limitations of the non-GAAP measure presented by providing the comparable GAAP measure with equal or greater prominence and descriptions of the reconciling items, including quantifying such items, to derive the non-GAAP measure. We encourage investors to examine the reconciling adjustments between the GAAP and non-GAAP measure, which we discuss below.

Definition of IAC's Non-GAAP Measure

Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization ("Adjusted EBITDA") is defined as operating income excluding: (1) stock-based compensation expense; (2) depreciation; and (3) acquisition-related items consisting of (i) amortization of intangible assets and impairments of goodwill and intangible assets, if applicable, and (ii) gains and losses recognized on changes in the fair value of contingent consideration arrangements. We believe this measure is useful for analysts and investors as this measure allows a more meaningful comparison between our performance and that of our competitors. Moreover, our management uses this measure internally to evaluate the performance of our business as a whole and our individual business segments, and this measure is one of the primary metrics by which our internal budgets are based and by which management is compensated. The above items are excluded from our Adjusted EBITDA measure because these items are non-cash in nature, and we believe that by excluding these items, Adjusted EBITDA corresponds more closely to the cash operating income generated from our business, from which capital investments are made and debt is serviced. Adjusted EBITDA has certain limitations in that it does not take into account the impact to IAC's statement of operations of certain expenses.

For a reconciliation of operating income (loss) by reportable segment and net earnings attributable to IAC shareholders to Adjusted EBITDA for the three months ended March 31, 2017 and 2016, see "Note 8—Segment Information" to the consolidated financial statements included in "Item 1—Consolidated Financial Statements."

Non-Cash Expenses That Are Excluded From IAC's Non-GAAP Measure

Stock-based compensationexpense consists principally of expense associated with the grants of stock options, restricted stock units ("RSUs"), performance-based RSUs and market-based awards. These expenses are not paid in cash, and we include the related shares in our fully diluted shares outstanding using the treasury stock method; however, performance-based RSUs and market-based awards are included only to the extent the applicable performance or market condition(s) has been met (assuming the end of the reporting period is the end of the contingency period). Upon the exercise of certain stock options and vesting of RSUs, performance-based RSUs and market-based awards, the awards are settled, at the Company's discretion, on a net basis, with the Company remitting the required tax-withholding amount from its current funds.

Depreciation is a non-cash expense relating to our property and equipment and is computed using the straight-line method to allocate the cost of depreciable assets to operations over their estimated useful lives or, in the case of leasehold improvements, the lease term, if shorter.

Amortization of intangible assets and impairments of goodwill and intangible assets are non-cash expenses related primarily to acquisitions. At the time of an acquisition, the identifiable definite-lived intangible assets of the acquired company, such as trade names, content, technology, customer lists, advertiser and supplier relationships, are valued and amortized over their estimated lives. Value is also assigned to acquired indefinite-lived intangible assets, which comprise trade names and trademarks, and goodwill that are not subject to amortization. An impairment is recorded when the carrying value of an intangible asset or goodwill exceeds its fair value. We believe that intangible assets represent costs incurred by the acquired company to build value prior to acquisition and the related amortization and impairment charges of intangible assets or goodwill, if applicable, are not ongoing costs of doing business.

Gains and losses recognized on changes in the fair value of contingent consideration arrangements are accounting adjustments to report contingent consideration liabilities at fair value. These adjustments can be highly variable and are

41

excluded from our assessment of performance because they are considered non-operational in nature and, therefore, are not indicative of current or future performance or the ongoing cost of doing business.

^(a)  Domestically, cash equivalents primarily consist of AAA rated government money market funds, commercial paper rated A1/P1 or better and treasury discount notes.

^(b)  Internationally, cash equivalents primarily consist of AAA rated treasury money market funds with maturities less than 91 days from the date of purchase, and time deposits with maturities of less than 91 days.

^(c)  If needed for our U.S. operations, most of the cash and cash equivalents held by the Company's foreign subsidiaries could be repatriated; however, under current law, would be subject to U.S. federal and state income taxes. We have not provided for any such tax because the Company currently does not anticipate a need to repatriate these funds to finance our U.S. operations and it is the Company's intent to indefinitely reinvest these funds outside of the U.S.

^(d)  Marketable securities consist of commercial paper rated A1/P1, treasury discount notes and short-to-medium-term debt securities issued by investment grade corporate issuers. The Company invests in marketable debt securities with active secondary or resale markets to ensure portfolio liquidity to fund current operations or satisfy other cash requirements as needed. The Company also may invest in equity securities as part of its investment strategy.

^(e)  At March 31, 2017 and December 31, 2016, cash and cash equivalents includes Match Group's domestic and international cash and cash equivalents of $266.1 million and $170.1 million; and $114.0 million and $139.6 million, respectively. Match Group is a separate and distinct legal entity with its own public shareholders and board of directors and has no obligation to provide the Company with funds. As a result, we cannot freely access the cash of Match Group and its subsidiaries. Match Group generated $90.0 million and $84.4 million of operating cash flows for the three months ended March 31, 2017 and 2016, respectively. In addition, agreements governing Match Group’s indebtedness limit the payment of dividends or distributions, loans or advances to stockholders, including the Company, in the event a default has occurred or Match Group's leverage ratio (as defined in the indentures) exceeds 5.0 to 1.0.

2017

Adjustments to earnings primarily consist of $34.0 million of stock-based compensation expense, $19.9 million of depreciation, $9.2 million of amortization of intangibles, $3.7 million of deferred income taxes, and $3.4 million of impairment of long-term investments. The deferred tax provision primarily relates to the settlement of stock-based awards. The decrease from changes in working capital consist primarily of a change in income taxes payable and receivable of $38.6 million, an increase in other assets of $15.9 million, an increase in accounts receivable of $13.9 million, partially offset by an increase in accounts payable and other current liabilities of $26.0 million. The change in income taxes payable and receivable primarily relates to the settlement of stock-based awards. The excess tax benefit from stock-based awards was $26.8 million. The increase in other assets is primarily related to an increase in prepaid marketing at HomeAdvisor and an increase in prepaid hosting service contracts at Match Group. The increase in accounts receivable is primarily due to revenue growth at HomeAdvisor and timing of payments at Match Group. The increase in accounts payable and other current liabilities is due to (i) an increase in accrued advertising at Match Group, Publishing and HomeAdvisor mainly due to increased expenses, (ii) an increase in payables at Match Group due to timing of payments, (iii) an increase in accrued interest relating to the Company's Senior Notes and Match Group Senior Notes due to timing of interest payments, partially offset by (iv) a decrease in accrued employee compensation and benefits mainly related to the payment of 2016 cash bonuses in 2017.

Net cash provided by investing activities includes net proceeds from sale of businesses and investments of $97.5 million, which is primarily relate to the proceeds from the sale of The Princeton Review, and purchases (net of sales and maturities) of marketable debt securities of $55.4 million, partially offset by $52.4 million of cash used for the HomeStars and MyBuilder acquisitions, and capital expenditures of $11.2 million, primarily related to Match Group and HomeAdvisor investments in internal development of software to support their products and services, as well as computer hardware.

Adjustments to earnings primarily consist of $31.2 million of stock-based compensation expense, $15.8 million of depreciation, $13.8 million of amortization of intangibles and $14.7 million of gains on the sale of a business and long-term investments. The decrease from changes in working capital consist primarily of a change in income taxes payable and receivable of $37.5 million and a decrease in accounts payable and other current liabilities of $10.8 million, partially offset by an increase in deferred revenue of $19.5 million. The change in income taxes payable and receivable is primarily due to the payment of 2015 tax liabilities in 2016 and the settlement of stock-based awards. The excess tax benefit from stock-based awards was $15.3 million.The decrease in accounts payable and other current liabilities is due to(i) a decrease in accrued

44

employee compensation and benefits mainly related to the payment of 2015 cash bonuses in 2016, (ii)a decrease in VAT payables related to timing of payments and (iii) a seasonal decrease in payables to suppliers at ShoeBuy, partially offset by an increase in accrued advertising expense at Match Group mainly due to increased expenses.The increase in deferred revenue ismainly due to growth in Match Group's membership revenue, partially offset by a decrease at Electus due to the timing of cash received related to various production deals.

Net cash used in investing activities in includes the purchase of time deposits (with maturities of greater than 90 days from the date of purchase) of $87.5 million, the purchase of marketable debt securities of $66.9 million and capital expenditures of $16.1 million, primarily related to the internal development of our software to support our products and services, partially offset by net proceeds from the sale of a business and long-term investments of $93.1 million, which mainly consists of proceeds from the sale of PriceRunner.

Liquidity and Capital Resources

The Company's principal sources of liquidity are its cash and cash equivalents and marketable securities as well as cash flows generated from operations. IAC has a $300 million revolving credit facility that expires on October 7, 2020. Match Group has a $500 million revolving credit facility that expires on October 7, 2020. At March 31, 2017, there were no outstanding borrowings under the IAC Credit Facility or the Match Group Credit Facility.

At March 31, 2017, IAC had 8.6 million shares remaining in its share repurchase authorization. IAC may purchase shares over an indefinite period of time on the open market and in privately negotiated transactions, depending on those factors IAC management deems relevant at any particular time, including, without limitation, market conditions, share price and future outlook.

IAC's consolidated cash and cash equivalents at March 31, 2017 were $1.4 billion, of which $436.2 million was held by Match Group. The Company generated $67.8 million of operating cash flows for the three months ended March 31, 2017, of which $90.0 million was generated by Match Group. Match Group is a separate and distinct legal entity with its own public shareholders and board of directors and has no obligation to provide the Company with funds. As a result, we cannot freely access the cash of the Match Group and its subsidiaries. In addition, agreements governing Match Group's indebtedness limit the payment of dividends or distributions and loans or advances to stockholders, including the Company, in the event a default has occurred or Match Group's leverage ratio (as defined in the indentures) exceeds 5.0 to 1.0.

The Company anticipates that it will need to make capital and other expenditures in connection with the development and expansion of its operations. The Company's 2017 capital expenditures are expected to be higher than 2016 by approximately 10% to 15%, driven, in part, by certain Corporate related expenditures and HomeAdvisor's sales center and corporate headquarters expansion. In April 2017, the Company paid $14.9 million related to the purchase of a 50% ownership interest in an aircraft. This aircraft is expected to replace the older of the Company's two existing jointly-owned aircrafts, which is currently being marketed for sale.

Awards made under our subsidiary denominated equity plans are settled on a net basis, with the award holder entitled to receive a payment in IAC shares equal to the intrinsic value of the award at exercise less an amount equal to the required cash tax withholding payment. Awards made to employees of Match Group subsidiaries may be settled in either IAC shares or Match Group shares, at our option. The tax withholding payment associated with these awards is made by the Company in cash on behalf of the employee at the time these awards are exercised; in the case of Match Group awards, the tax withholding payment is made by Match Group in cash at the time these awards are exercised. In either case, the cash tax withholding payments will vary based on the ultimate number of awards exercised, the intrinsic value of the awards upon exercise and relevant withholding tax rates. We expect a reduction in future corporate income taxes equal to a substantial portion of any such withholding tax payments by virtue of the income tax deduction we will recognize based on the intrinsic value of the awards at exercise. However, there may be some delay in the timing of the realization of the cash benefit of the income tax deduction because it will be dependent upon the amount and timing of future taxable income and the timing of estimated income tax payments. As it relates to awards made to employees of Match Group subsidiaries, if the Company elects to settle these awards in IAC shares, we will receive Match Group shares equal in value to the IAC shares issued.  If the Company elects to settle these awards in Match Group shares, our ownership interest in Match Group will be diluted. The Match Group subsidiary denominated equity plan at Tinder has a number of scheduled option exercise periods, and the next period is in May

45

2017; the Company currently expects to settle a sufficient number of exercises in IAC shares to maintain an economic interest in Match Group of at least 80%. For additional discussion of subsidiary denominated equity plans, including potential cash withholding tax requirements, see "Note-13 Stock-Based Compensation" to the consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2016.

The Company believes its existing cash, cash equivalents, marketable securities and expected positive cash flows generated from operations will be sufficient to fund our normal operating requirements, including capital expenditures, debt service, the payment of withholding taxes on behalf of employees for net-settled stock-based awards, and investing and other commitments for the foreseeable future. The Company's liquidity could be negatively affected by a decrease in demand for our products and services. The Company’s indebtedness could limit our ability to: (i) obtain additional financing to fund working capital needs, acquisitions, capital expenditure or debt service or other requirements; and (ii) use operating cash flow to make acquisitions, capital expenditures, invest in other areas, such as developing properties and exploiting business opportunities, in the event a default has occurred or in certain circumstances our leverage ratio (as defined in the indenture) exceeds 3.0 to 1.0. The Company may make additional acquisitions and investments and, as a result, the Company may need to raise additional capital through future debt or equity financing to provide for greater financial flexibility. Additional financing may not be available at all or on terms favorable to us.

Item 4.    Controls and Procedures

The Company monitors and evaluates on an ongoing basis its disclosure controls and internal control over financial reporting in order to improve its overall effectiveness. In the course of these evaluations, the Company modifies and refines its internal processes as conditions warrant.

As required by Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), IAC management, including our principal executive and principal financial officers, or persons performing similar functions, evaluated the effectiveness of the Company's disclosure controls and procedures as defined by Rule 13a-15(e) under the Exchange Act. Based on this evaluation, management has concluded that the Company's disclosure controls and procedures were effective as of the end of the period covered by this report in providing reasonable assurance that information we are required to disclose in our filings with the Securities and Exchange Commission under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Commission's rules and Forms, and include controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

There were no changes to the Company's internal control over financial reporting during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II

OTHER INFORMATION

Item 1. Legal Proceedings

Overview

In the ordinary course of business, the Company and its subsidiaries are parties to litigation involving property, personal injury, contract, intellectual property and other claims, as well as stockholder derivative actions, class action lawsuits and other matters. The amounts that may be recovered in such matters may be subject to insurance coverage. Although the results of legal proceedings and claims cannot be predicted with certainty, neither the Company nor any of our subsidiaries is currently a party to any legal proceedings the outcome of which, we believe, if determined adversely to us, would individually or in the aggregate have a material adverse effect on our business, financial condition or results of operations. 

Rules of the Securities and Exchange Commission require the description of material pending legal proceedings (other than ordinary, routine litigation incident to the registrant’s business) and advise that proceedings ordinarily need not be described if they primarily involve damages claims for amounts (exclusive of interest and costs) not exceeding 10% of the current assets of the registrant and its subsidiaries on a consolidated basis. In the judgment of IAC management, none of the pending litigation matters which we are defending, including those described below, involves or is likely to involve amounts of that magnitude. The litigation matters described below involve issues or claims that may be of particular interest to our stockholders, regardless of whether any of these matters may be material to our financial position or operations based upon the standard set forth in the rules of the Securities and Exchange Commission.

Delaware Law Class Action Litigation against IAC

On November 21, 2016, following the Company’s announcement in its Definitive Proxy Statement of a proposal to adjust the Company’s capital structure by adopting an amendment and restatement of the Company’s certificate of incorporation (the “New Certificate”) to establish a new class of non-voting capital stock, which would be known as Class C common stock, and potentially declaring and paying a dividend of one share of the Class C common stock for each outstanding share of IAC common stock and Class B common stock (the “Dividend” and, together with the adoption of the New Certificate, the “Class C Issuance”), a putative class action lawsuit was filed in the Delaware Court of Chancery against the Company and its Board of Directors purportedly on behalf of the Company’s stockholders. See Miller et al. v. IAC/InterActiveCorp et al., C.A. No. 12929-VCL (Del. Ch. Ct.).  The lawsuit generally alleged, among other things, that IAC’s directors breached their fiduciary duties in connection with the proposed Class C Issuance inasmuch as it was allegedly designed to unduly benefit the Company’s Chairman and Senior Executive, Barry Diller, in respect of his alleged voting control of the Company and would harm IAC’s public stockholders.  Among other remedies, the lawsuit sought to enjoin the filing of the New Certificate with the Delaware Secretary of State, as well as unspecified money damages.

On November 22, 2016 and December 12, 2016, two additional putative class action lawsuits were filed in the Delaware Court of Chancery against the Company and its Board of Directors purportedly on behalf of the Company’s stockholders and asserting substantially similar allegations, claims and remedies as in the Miller lawsuit. See Halberstam v. Bronfman et al., C.A. No. 12935-VCL (Del. Ch. Ct.), and California Public Employees’ Retirement System v. IAC/InterActiveCorp et al., No. 12975-VCL (Del. Ch. Ct.).  All three lawsuits have been consolidated as In re IAC/InterActiveCorp Class C Reclassification Litigation, No. 12975-VCL, and the Court has designated the CalPERS complaint as the operative complaint in the case and established a case schedule.  On January 23, 2017 and February 3, 2017, the defendants filed answers denying the material allegations of the complaint.  The case is currently in discovery.

While the Class C Issuance was approved at the Company's 2016 Annual Meeting of Stockholders, the Company has agreed not to effect the Class C Issuance during the pendency of the lawsuit described immediately above, and the Delaware Court of Chancery has been so informed.

We believe that this lawsuit, and the material allegations and claims therein, are without merit and intend to continue to defend against them vigorously.

Securities Class Action Litigation against Match Group

As previously disclosed in our 2016 quarterly reports on Form 10-Q and Annual Report on Form 10-K for the fiscal year ended December 31, 2016, on February 26, 2016, a putative nationwide class action was filed in federal court in Texas against Match Group, five of its officers and directors, and twelve underwriters of Match Group's initial public offering in November 2015. See David M. Stein v. Match Group, Inc. et al., No. 3:16-cv-549 (U.S. District Court, Northern District of Texas).  The complaint alleged that Match Group's registration statement and prospectus issued in connection with its initial public offering were materially false and misleading given their failure to state that: (i) Match Group's Non-dating business would miss its revenue projection for the quarter ended December 31, 2015, and (ii) ARPPU (as defined in "Item 2-Management's Discussion and Analysis of Financial Condition and Results of Operations-General-Key Terms") would decline substantially in the quarter ended December 31, 2015.  The complaint asserted that these alleged failures to timely disclose material information caused Match Group's stock price to drop after the announcement of its earnings for the quarter ended December 31, 2015.  The complaint pleaded claims under the Securities Act of 1933 for untrue statements of material fact in, or omissions of material facts from, the registration statement, the prospectus, and related communications in violation of Sections 11 and 12 and, as to the officer/director defendants only, control-person liability under Section 15 for Match Group’s alleged violations.  The complaint sought among other relief class certification and damages in an unspecified amount.

On March 9, 2016, a virtually identical class action complaint was filed in the same court against the same defendants by a different named plaintiff. See Stephany Kam-Wan Chan v. Match Group, Inc. et al., No. 3:16-cv-668 (U.S. District Court, Northern District of Texas).  On April 25, 2016, Judge Boyle in the Chan case issued an order granting the parties’ joint motion to transfer that case to Judge Lindsay, who is presiding over the earlier-filed Stein case.  On April 27, 2016, various current or former Match Group shareholders and their respective law firms filed motions seeking appointment as lead plaintiff(s) and lead or liaison counsel for the putative class.  On April 28, 2016, the Court issued orders: (i) consolidating the Chan case into the Stein case, (ii) approving the parties’ stipulation to extend the defendants’ time to respond to the complaint until after the Court has appointed a lead plaintiff and lead counsel for the putative class and has set a schedule for the plaintiff’s filing of a consolidated complaint and the defendants’ response to that pleading, and (iii) referring the various motions for appointment of lead plaintiff(s) and lead or liaison counsel for the putative class to a United States Magistrate Judge for determination.  In accordance with this order, the consolidated case is now captioned Mary McCloskey et ano. v. Match Group, Inc. et al., No. 3:16-CV-549-L.  On June 9, 2016, the Magistrate Judge issued an order appointing two lead plaintiffs, two law firms as co-lead plaintiffs’ counsel, and a third law firm as plaintiffs’ liaison counsel.

On July 27, 2016, the parties submitted to the Court a joint status report proposing a schedule for the plaintiffs’ filing of a consolidated amended complaint and the parties’ briefing of the defendants’ contemplated motion to dismiss the consolidated complaint. On August 17, 2016, the Court issued an order approving the parties’ proposed schedule.  On September 9, 2016, in accordance with the schedule, the plaintiffs filed an amended consolidated complaint.  The new pleading focuses solely on allegedly misleading statements or omissions concerning the Match Group’s Non-dating business. The defendants filed motions to dismiss the amended consolidated complaint on November 8, 2016. The plaintiffs filed oppositions to the motions on December 23, 2016, and the defendants filed replies to the oppositions on February 6, 2017.  We and Match Group believe that the allegations in these lawsuits, and the material allegations and claims therein, are without merit and intend to continue to defend against them vigorously.

Item 1A.    Risk Factors

Cautionary Statement Regarding Forward-Looking Information

This quarterly report on Form 10-Q contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. The use of words such as "anticipates," "estimates," "expects," "plans" and "believes," among others, generally identify forward-looking statements. These forward-looking statements include, among others, statements relating to: IAC's future financial performance, IAC's business prospects and strategy, anticipated trends and prospects in the industries in which IAC's businesses operate and other similar matters. These forward-looking statements are based on IAC management's current expectations and assumptions about future events, which are inherently subject to uncertainties, risks and changes in circumstances that are difficult to predict.

Actual results could differ materially from those contained in these forward-looking statements for a variety of reasons, including, among others: changes in senior management at IAC and/or its businesses, changes in our relationship with, or policies implemented by, Google, adverse changes in economic conditions, either generally or in any of the markets or

51

industries in which IAC's businesses operate, adverse trends in any of the industries in which IAC's businesses operate (primarily the online advertising, general advertising and dating industries), our dependence on third parties in connection with the distribution and use of our products and services, our ability to offer new or alternative products and services in a cost-effective manner and consumer acceptance of these products and services, our ability to attract and convert visitors to our various websites into users and customers, our ability to build, maintain and/or enhance our various brands, foreign exchange currency rate fluctuations, our ability to develop and monetize mobile versions of our various products and services, changes in industry standards and technology, the integrity and scalability of our systems and infrastructure (and those of third parties), our ability to protect our systems from cyberattacks and to protect personal and confidential user information, dilution with respect to our investment in Match Group, Inc., operational and financial risks relating to acquisitions, the occurrence of any event, change or other circumstances that results in the termination of the agreement with Angie's List, our ability to expand successfully into international markets and regulatory changes. Certain of these and other risks and uncertainties are discussed in IAC's filings with the SEC, including in Part I "Item 1A. Risk Factors" of our Annual Report on Form 10-K for the fiscal year ended December 31, 2016. Other unknown or unpredictable factors that could also adversely affect IAC's business, financial condition and operating results may arise from time to time. In light of these risks and uncertainties, the forward-looking statements discussed in this report may not prove to be accurate. Accordingly, you should not place undue reliance on these forward-looking statements, which only reflect the views of IAC management as of the date of this quarterly report. IAC does not undertake to update these forward-looking statements.

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

3 Months Ended

Mar. 31, 2017

Organization, Consolidation and Presentation of Financial Statements [Abstract]

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

IAC is a leading media and Internet company comprised of widely known consumer brands, such as HomeAdvisor, Vimeo, Dotdash (formerly About.com), Dictionary.com, The Daily Beast, Investopedia, and Match Group's online dating portfolio, which includes Match, Tinder, PlentyOfFish and OkCupid.

All references to "IAC," the "Company," "we," "our" or "us" in this report are to IAC/InterActiveCorp.

On March 31, 2017, Match Group sold its non-dating business, consisting of The Princeton Review. The non-dating business does not meet the threshold to be reflected as a discontinued operation at the IAC level. The Company has moved the non-dating business to its “Other” segment as of and for the quarter ended March 31, 2017 and prior period segment data has been recast to conform to the current period presentation.

Basis of Presentation

The Company prepares its consolidated financial statements in accordance with U.S. generally accepted accounting principles ("GAAP").

Basis of Consolidation and Accounting for Investments

The consolidated financial statements include the accounts of the Company, all entities that are wholly-owned by the Company and all entities in which the Company has a controlling financial interest. Intercompany transactions and accounts have been eliminated.

Investments in the common stock or in-substance common stock of entities in which the Company has the ability to exercise significant influence over the operating and financial matters of the investee, but does not have a controlling financial interest, are accounted for using the equity method and are included in "Long-term investments" in the accompanying consolidated balance sheet.

The accompanying unaudited consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation. Interim results are not necessarily indicative of the results that may be expected for the full year. The accompanying unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016.

Accounting Estimates

Management of the Company is required to make certain estimates, judgments and assumptions during the preparation of its consolidated financial statements in accordance with GAAP. These estimates, judgments and assumptions impact the reported amounts of assets, liabilities, revenue and expenses and the related disclosure of contingent assets and liabilities. Actual results could differ from these estimates.

On an ongoing basis, the Company evaluates its estimates and judgments including those related to: the fair values of marketable securities and other investments; the recoverability of goodwill and indefinite-lived intangible assets; the useful lives and recoverability of definite-lived intangible assets and property and equipment; the carrying value of accounts receivable, including the determination of the allowance for doubtful accounts; the determination of revenue reserves; the fair value of acquisition-related contingent consideration arrangements; the liabilities for uncertain tax positions; the valuation allowance for deferred income tax assets; and the fair value of and forfeiture rates for stock-based awards, among others. The Company bases its estimates and judgments on historical experience, its forecasts and budgets and other factors that the Company considers relevant.

Certain Risks and Concentrations

A significant portion of the Company's revenue is derived from online advertising, the market for which is highly competitive and rapidly changing. Significant changes in this industry or changes in advertising spending behavior or in customer buying behavior could adversely affect our operating results. Most of the Company's online advertising revenue is attributable to a services agreement with Google Inc. ("Google"). For the three months ended March 31, 2017 and 2016, revenue from Google represents 25% and 35%, respectively, of the Company's consolidated revenue. The Company's services agreement became effective on April 1, 2016, following the expiration of the previous services agreement. The services agreement expires on March 31, 2020; however, the Company may choose to terminate the agreement effective March 31, 2019. The services agreement requires that we comply with certain guidelines promulgated by Google. Google may generally unilaterally update its policies and guidelines without advance notice, which could in turn require modifications to, or prohibit and/or render obsolete certain of our products, services and/or business practices, which could be costly to address or otherwise have an adverse effect on our business, financial condition and results of operations. For the three months endedMarch 31, 2017 and 2016, revenue earned from Google was $187.8 million and $284.6 million, respectively. This revenue is earned by the businesses comprising the Applications and Publishing segments. For the three months endedMarch 31, 2017 and 2016, revenue earned from Google represents 84% and 70%; and 91% and 83%, of Applications and Publishing revenue, respectively. Accounts receivable related to revenue earned from Google totaled $65.5 million and $65.8 million at March 31, 2017 and December 31, 2016, respectively.

Recent Accounting Pronouncements

Accounting Pronouncements not yet adopted by the Company

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers, which clarifies the principles for recognizing revenue and develops a common standard for all industries. ASU 2014-09 was subsequently amended during 2015 and 2016; these amendments provide further revenue recognition guidance related to principal versus agent considerations, performance obligations and licensing, and narrow-scope improvements and practical expedients.

ASU No. 2014-09 is a comprehensive revenue recognition standard that will supersede nearly all existing revenue recognition guidance under GAAP. The new standard provides a single principles-based, five-step model to be applied to all contracts with customers. This five-step model includes (1) identifying the contract(s) with the customer, (2) identifying the performance obligations in the contract, (3) determining the transaction price, (4) allocating the transaction price to the performance obligations in the contract and (5) recognizing revenue when each performance obligation is satisfied. More specifically, revenue will be recognized when promised goods or services are transferred to the customer in an amount that reflects the consideration expected in exchange for those goods or services. ASU No. 2014-09 is effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption permitted for interim and annual reporting periods beginning after December 15, 2016. Upon adoption, ASU No. 2014-09 may either be applied retrospectively to each prior period presented or using the modified retrospective approach with the cumulative effect recognized as of the date of initial application.

While the Company’s evaluation of the impact the adoption of ASU No. 2014-09 on its consolidated financial statements continues, it has progressed to the point where we have reached certain preliminary determinations. The Company does not expect the adoption of ASU No. 2014-09 to have a material effect on its consolidated financial statements. The Company will adopt ASU No. 2014-09 using the modified retrospective approach effective January 1, 2018. Therefore, the cumulative effect of adoption will be reflected as an adjustment to beginning retained earnings in the Form 10-Q for the period ending March 31, 2018. The adoption of ASU No. 2014-09 will primarily affect the Company’s HomeAdvisor and Applications segments. The effect on HomeAdvisor will be that sales commissions, which represent the incremental direct costs of obtaining a service professional contract, will be capitalized and amortized over the average life of a service professional. These costs are expensed as incurred today. Within Applications, the primary effect will be to accelerate the recognition of the portion of the revenue of certain desktop applications sold by SlimWare that qualify as functional intellectual property under ASU No. 2014-09. This revenue is currently deferred and recognized over the applicable subscription term.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which supersedes existing guidance on accounting for leases in "Leases (Topic 840)" and generally requires all leases to be recognized in the statement of financial position. The provisions of ASU No. 2016-02 are effective for reporting periods beginning after December 15, 2018; early adoption is permitted. The provisions of ASU No. 2016-02 are to be applied using a modified retrospective approach. The Company is currently evaluating the impact the adoption of this standard update will have on its consolidated financial statements.

Accounting Pronouncements adopted by the Company

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which clarifies how cash receipts and cash payments in certain transactions are presented and classified on the statement of cash flows. The provisions of ASU No. 2016-15 are effective for reporting periods beginning after December 15, 2017, including interim periods, and will require adoption on a retrospective basis unless it is impracticable to apply, in which case we would be required to apply the amendments prospectively as of the earliest date practicable; early adoption is permitted. Upon adoption, cash payments not made soon after the acquisition date of a business combination to settle a contingent consideration liability are separated and classified as cash outflows for operating activities and financing activities. Cash payments up to the amount of the contingent consideration liability recognized at the acquisition date (including measurement-period adjustments) are classified as financing activities; any excess is classified as operating activities. Cash payments made soon after the acquisition date of a business combination by an acquirer to settle a contingent consideration liability are classified as cash outflows for investing activities. The Company early adopted the provisions of ASU No. 2016-15 on January 1, 2017. As a result of the adoption of ASU No. 2016-15, $11.1 million of acquisition-related contingent consideration payments for the three months ended March 31, 2017 was in excess of the liability recognized at the acquisition date and, therefore, has been classified as a cash outflow in "Other adjustments, net" within net cash provided by operating activities in the accompanying consolidated statement of cash flows.

In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The Company adopted the provisions of ASU No. 2016-09 on January 1, 2017. Excess tax benefits or deficiencies related to equity awards to employees upon exercise of stock options and the vesting of restricted stock units after January 1, 2017 are (i) reflected in the consolidated statement of operations as a component of the provision for income taxes, rather than recognized in equity, and (ii) reflected as operating, rather than financing, cash flows in our consolidated statement of cash flows. Excess tax benefits for the three months ended March 31, 2017 were $26.8 million. Excess tax benefits of $15.3 million for the three months ended March 31, 2016 were reclassified in the consolidated statement of cash flows to conform to the current year presentation. Upon adoption, the calculation of fully diluted shares excludes excess tax benefits from the assumed proceeds in applying the treasury stock method, they previously were included in the calculation; this change increased fully diluted shares by approximately 1.3 million shares for the three months ended March 31, 2017. The Company continues to account for forfeitures using an estimated forfeiture rate.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which is intended to simplify the accounting for goodwill impairment. The guidance eliminates the requirement to calculate the implied fair value of goodwill under today’s two-step impairment test to measure a goodwill impairment charge. The provisions of ASU No. 2017-04 are effective for reporting periods beginning after December 15, 2019; early adoption is permitted. The provisions of ASU No. 2017-04 are to be applied using a prospective approach. The Company early adopted the provisions of ASU No. 2017-04 on January 1, 2017 and the adoption of this standard update did not have a material impact on its consolidated financial statements.

Reclassifications

Certain prior year amounts have been reclassified to conform to the current year presentation.

INCOME TAXES

Income Tax Disclosure [Abstract]

INCOME TAXES

INCOME TAXES

At the end of each interim period, the Company makes its best estimate of the annual expected effective income tax rate and applies that rate to its ordinary year-to-date earnings or loss. The income tax provision or benefit related to significant, unusual, or extraordinary items, if applicable, that will be separately reported or reported net of their related tax effects are individually computed and recognized in the interim period in which they occur. In addition, the effect of changes in enacted tax laws or rates, tax status, judgment on the realizability of a beginning-of-the-year deferred tax asset in future years or the liabilities for uncertain tax positions is recognized in the interim period in which the change occurs.

The computation of the annual expected effective income tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected pre-tax income (or loss) for the year, projections of the proportion of income (and/or loss) earned and taxed in foreign jurisdictions, permanent and temporary differences, and the likelihood of the realization of deferred tax assets generated in the current year. The accounting estimates used to compute the provision or benefit for income taxes may change as new events occur, more experience is acquired, additional information is obtained or our tax environment changes. To the extent that the expected annual effective income tax rate changes during a quarter, the effect of the change on prior quarters is included in income tax provision in the quarter in which the change occurs.

For the three months endedMarch 31, 2017, the Company recorded an income tax benefit of $23.9 million. The income tax benefit for the three months endedMarch 31, 2017 is due primarily to the effect of adopting the provisions of ASU No. 2016-09 on January 1, 2017. Under ASU No. 2016-09, excess tax benefits generated by the settlement or exercise of stock-based awards of $26.8 million are recognized as a reduction to the income tax provision rather than additional paid-in capital. For the three months ended March 31, 2016, the Company recorded an income tax provision of $1.5 million which represents an effective income tax rate of 16%. The effective tax rate for the three months ended March 31, 2016 is lower than the statutory rate of 35% due primarily to the non-taxable gain on the sale of PriceRunner, partially offset by the non-deductible loss on contingent consideration fair value adjustments and the unbenefited loss associated with the other-than-temporary impairment charges related to certain of the Company's cost method investments.

The Company recognizes interest and, if applicable, penalties related to unrecognized tax benefits in the income tax provision. At March 31, 2017 and December 31, 2016, the Company has accrued $2.7 million and $2.6 million, respectively, for the payment of interest. At March 31, 2017 and December 31, 2016, the Company has accrued $1.6 million and $1.7 million, respectively, for penalties.

The Company is routinely under audit by federal, state, local and foreign authorities in the area of income tax. These audits include questioning the timing and the amount of income and deductions and the allocation of income and deductions among various tax jurisdictions. The Internal Revenue Service is currently auditing the Company’s federal income tax returns for the years ended December 31, 2010 through 2012. The statute of limitations for the years 2010 through 2012 has been extended to December 31, 2017. Various other jurisdictions are open to examination for tax years beginning with 2009. Income taxes payable include reserves considered sufficient to pay assessments that may result from examination of prior year tax returns. Changes to reserves from period to period and differences between amounts paid, if any, upon resolution of audits and amounts previously provided may be material. Differences between the reserves for income tax contingencies and the amounts owed by the Company are recorded in the period they become known.

At March 31, 2017 and December 31, 2016, unrecognized tax benefits, including interest and penalties, are $40.1 million and $41.0 million, respectively. If unrecognized tax benefits at March 31, 2017 are subsequently recognized, $36.9 million, net of related deferred tax assets and interest, would reduce income tax expense. The comparable amount as of December 31, 2016 was $37.7 million. The Company believes that it is reasonably possible that its unrecognized tax benefits could decrease by $11.8 million by March 31, 2018, due to expirations of statutes of limitations and settlements; $11.1 million of which would reduce the income tax provision.

MARKETABLE SECURITIES

At March 31, 2017, available-for-sale marketable securities are as follows:

	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
	(In thousands)

Total marketable securities	$	33,997	$	—	$	(5	)	$	33,992

The contractual maturities of debt securities classified as available-for-sale at March 31, 2017 are due within one year.

The aggregate fair value of available-for-sale marketable debt securities in an unrealized loss position is $12.0 million as of March 31, 2017. There are no investments in available-for-sale marketable debt securities that have been in a continuous unrealized loss position for longer than twelve months as of March 31, 2017. The gross unrealized losses on the marketable debt securities relate primarily to changes in interest rates. The Company does not consider the gross unrealized losses to be other-than-temporary because the Company does not intend to sell the marketable debt securities that generated the gross unrealized losses at March 31, 2017, and it is not more likely than not that the Company will be required to sell these securities before recovery of their amortized costs bases, which may be maturity.

At December 31, 2016, available-for-sale marketable securities are as follows:

	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
	(In thousands)
Commercial paper	$	49,797	$	—	$	—		$	49,797

There were no gross realized gains or losses from the maturities and sales of available-for-sale marketable securities for the three months endedMarch 31, 2017 and 2016.

The specific-identification method is used to determine the cost of securities sold and the amount of unrealized gains and losses reclassified out of accumulated other comprehensive income (loss) into earnings.

FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS

FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS

The Company categorizes its financial instruments measured at fair value into a fair value hierarchy that prioritizes the inputs used in pricing the asset or liability. The three levels of the fair value hierarchy are:

• Level 1: Observable inputs obtained from independent sources, such as quoted prices for identical assets and liabilities in active markets.

• Level 2: Other inputs, which are observable directly or indirectly, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and inputs that are derived principally from or corroborated by observable market data. The fair values of the Company's Level 2 financial assets are primarily obtained from observable market prices for identical underlying securities that may not be actively traded. Certain of these securities may have different market prices from multiple market data sources, in which case an average market price is used.

Contingent Consideration Arrangements

As of March 31, 2017, there are five contingent consideration arrangements related to business acquisitions. The maximum contingent payments related to these five arrangements are $121.1 million and the fair value of these arrangements at March 31, 2017 is $21.8 million.

The contingent consideration arrangements are generally based upon earnings performance and/or operating metrics. The Company determines the fair value of the contingent consideration arrangements by using probability-weighted analyses to determine the amounts of the gross liability, and, if the arrangement is long-term in nature, applying a discount rate that appropriately captures the risks associated with the obligation to determine the net amount reflected in the consolidated financial statements. The number of scenarios in the probability-weighted analyses can vary; generally, more scenarios are prepared for longer duration and more complex arrangements. The fair values of the contingent consideration arrangements at both March 31, 2017 and December 31, 2016 reflect discount rates of 12%.

The fair values of the contingent consideration arrangements are sensitive to changes in the forecasts of earnings and/or the relevant operating metrics and changes in discount rates. The Company remeasures the fair value of the contingent consideration arrangements each reporting period, including the accretion of the discount, if applicable, and changes are recognized in “General and administrative expense” in the accompanying consolidated statement of operations. The contingent consideration arrangement liability at March 31, 2017 and December 31, 2016 includes a current portion of $21.4 million and $33.4 million, respectively, and non-current portion of $0.5 million and $0.4 million, respectively, which are included in “Accrued expenses and other current liabilities” and “Other long-term liabilities,” respectively, in the accompanying consolidated balance sheet.

Assets measured at fair value on a nonrecurring basis

The Company's non-financial assets, such as goodwill, intangible assets and property and equipment, as well as equity and cost method investments, are adjusted to fair value only when an impairment charge is recognized. Such fair value measurements are based predominantly on Level 3 inputs.

Cost method investments

At March 31, 2017 and December 31, 2016, the carrying values of the Company's investments accounted for under the cost method totaled $112.7 million and $116.1 million, respectively, and are included in "Long-term investments" in the accompanying consolidated balance sheet. The Company evaluates each cost method investment for impairment on a quarterly basis and recognizes an impairment loss if a decline in value is determined to be other-than-temporary. If the Company has not identified events or changes in circumstances that may have a significant adverse effect on the fair value of a cost method investment, then the fair value of such cost method investment is not estimated, as it is impracticable to do so.

Financial instruments measured at fair value only for disclosure purposes

The following table presents the carrying value and the fair value of financial instruments measured at fair value only for disclosure purposes:

	March 31, 2017						December 31, 2016
	Carrying Value			Fair Value			Carrying Value			Fair Value

The fair value of long-term debt, including the current portion, is estimated using market prices or indices for similar liabilities and takes into consideration other factors such as credit quality and maturity, which are Level 3 inputs.

^(a)  The Match Group Term Loan matures on November 16, 2022; provided that, if any of the 2015 Match Group Senior Notes remain outstanding on the date that is 91 days prior to the maturity date of the 2015 Match Group Senior Notes, the Match Group Term Loan maturity date shall be the date that is 91 days prior to the maturity date of the 2015 Match Group Senior Notes.

Match Group Senior Notes:

The 2016 Match Group Senior Notes were issued on June 1, 2016. The proceeds of $400 million were used to prepay a portion of indebtedness outstanding under the Match Group Term Loan. At any time prior to June 1, 2019, these notes may be redeemed at a redemption price equal to the sum of the principal amount thereof, plus accrued and unpaid interest and a make-whole premium. Thereafter, these notes may be redeemed at redemption prices set forth in the indenture governing the notes, together with accrued and unpaid interest thereon to the applicable redemption date.

The 2015 Match Group Senior Notes were issued on November 16, 2015, in exchange for a portion of the IAC 2012 Senior Notes (the "Match Exchange Offer"). At any time prior to December 15, 2017, the 2015 Match Group Senior Notes may be redeemed at a redemption price equal to the sum of the principal amount thereof, plus accrued and unpaid interest and a make-whole premium. Thereafter, these notes may be redeemed at redemption prices set forth in the indenture governing the notes, together with accrued and unpaid interest thereon to the applicable redemption date.

The indentures governing the 2016 and 2015 Match Group Senior Notes contain covenants that would limit Match Group's ability to pay dividends or to make distributions and repurchase or redeem Match Group stock in the event a default has occurred or Match Group's leverage ratio (as defined in the indentures) exceeds 5.0 to 1.0. At March 31, 2017 there were no limitations pursuant thereto. There are additional covenants that limit Match Group's ability and the ability of its subsidiaries to, among other things, (i) incur indebtedness, make investments, or sell assets in the event Match Group is not in compliance with the leverage ratio set forth in the indenture, and (ii) incur liens, enter into agreements restricting Match Group subsidiaries' ability to pay dividends, enter into transactions with affiliates and consolidate, merge or sell substantially all of their assets.

Match Group Term Loan and Match Group Credit Facility:

On November 16, 2015, under a credit agreement (the "Match Group Credit Agreement"), Match Group borrowed $800 million in the form of a term loan (the "Match Group Term Loan"). On March 31, 2016, Match Group made a $10 million principal payment on the Match Group Term Loan. On June 1, 2016, the $400 million in proceeds from the 2016 Match Group Senior Notes, described above, were used to prepay a portion of the Match Group Term Loan. On December 8, 2016, Match Group made an additional $40 million principal payment on the Match Group Term Loan and the remaining outstanding balance of $350 million, which is due at maturity, was repriced. The Match Group Term Loan provides for additional annual principal payments as part of an excess cash flow sweep provision, the amount of which, if any, is governed by the secured net leverage ratio contained in the Match Group Credit Agreement. The Match Group Term Loan bears interest, at Match Group's option, at a base rate or LIBOR, plus 2.25% or 3.25%, respectively, and in the case of LIBOR, a floor of 0.75%. The interest rate on the Match Group Term Loan at March 31, 2017 is 4.10%. Interest payments are due at least semi-annually through the term of the loan.

Match Group has a $500 million revolving credit facility (the "Match Group Credit Facility") that expires on October 7, 2020. At March 31, 2017 and December 31, 2016, there were no outstanding borrowings under the Match Group Credit Facility. The annual commitment fee on undrawn funds based on the current leverage ratio is 30 basis points. Borrowings under the Match Group Credit Facility bear interest, at Match Group's option, at a base rate or LIBOR, in each case plus an applicable margin, which is determined by reference to a pricing grid based on Match Group's consolidated net leverage ratio. The terms of the Match Group Credit Facility require Match Group to maintain a consolidated net leverage ratio of not more than 5.0 to 1.0 and a minimum interest coverage ratio of not less than 2.5 to 1.0 (in each case as defined in the agreement).

There are additional covenants under the Match Group Credit Facility and the Match Group Term Loan that limit the ability of Match Group and its subsidiaries to, among other things, incur indebtedness, pay dividends or make distributions. While the Match Group Term Loan remains outstanding, these same covenants under the Match Group Credit Agreement are more restrictive than the covenants that are applicable to the Match Group Credit Facility. Obligations under the Match Group Credit Facility and Match Group Term Loan are unconditionally guaranteed by certain Match Group wholly-owned domestic subsidiaries, and are also secured by the stock of certain Match Group domestic and foreign subsidiaries. The Match Group Term Loan and outstanding borrowings, if any, under the Match Group Credit Facility rank equally with each other, and have priority over the 2016 and 2015 Match Group Senior Notes to the extent of the value of the assets securing the borrowings under the Match Group Credit Agreement.

IAC Senior Notes:

The 2013 and 2012 Senior Notes were issued by IAC on November 15, 2013 and December 21, 2012, respectively. The 2013 and 2012 Senior Notes are unconditionally guaranteed by certain wholly-owned domestic subsidiaries, which are designated as guarantor subsidiaries, except neither Match Group nor any of its subsidiaries guarantee any debt of IAC, or are subject to any of the covenants related to such debt. The guarantor subsidiaries are the same for the 2013 and 2012 Senior Notes. See "Note 11—Guarantor and Non-guarantor Financial Information" for financial information relating to guarantor and non-guarantor.

For the three months ended March 31, 2017, the Company redeemed and repurchased $23.3 million of its 2013 Senior Notes and called an additional $5.0 million for redemption, and repurchased $3.3 million of its 2012 Senior Notes. For the three months ended March 31, 2016, the Company redeemed and repurchased $30.0 million of its 2013 Senior Notes and repurchased $2.9 million of its 2012 Senior Notes.

The indenture governing the 2013 Senior Notes contains covenants that would limit our ability to pay dividends or to make distributions and repurchase or redeem our stock in the event a default has occurred or our leverage ratio (as defined in the indenture) exceeds 3.0 to 1.0. At March 31, 2017, there were no limitations pursuant thereto. There are additional covenants that limit the Company's ability and the ability of its restricted subsidiaries to, among other things, (i) incur indebtedness, make investments, or sell assets in the event we are not in compliance with the financial ratio set forth in the indenture, and (ii) incur liens, enter into agreements limiting our restricted subsidiaries' ability to pay dividends, enter into transactions with affiliates and consolidate, merge or sell substantially all of our assets. The indenture governing the 2012 Senior Notes was amended to eliminate substantially all of the restrictive covenants contained therein in connection with the Match Exchange Offer.

IAC Credit Facility:

IAC has a $300.0 million revolving credit facility (the "IAC Credit Facility") that expires October 7, 2020. At March 31, 2017 and December 31, 2016, there were no outstanding borrowings under the IAC Credit Facility. The annual commitment fee on undrawn funds is currently 35 basis points, and is based on the leverage ratio most recently reported. Borrowings under the IAC Credit Facility bear interest, at the Company's option, at a base rate or LIBOR, in each case, plus an applicable margin, which is determined by reference to a pricing grid based on the Company's leverage ratio. The terms of the IAC Credit Facility require that the Company maintains a leverage ratio (as defined in the agreement) of not more than 3.25 to 1.0 and restrict our ability to incur additional indebtedness. Borrowings under the IAC Credit Facility are unconditionally guaranteed by the same domestic subsidiaries that guarantee the 2013 and 2012 Senior Notes and are also secured by the stock of certain of our domestic and foreign subsidiaries. The 2013 and 2012 Senior Notes rank equally with each other, and are subordinate to outstanding borrowings under the IAC Credit Facility to extent of the value of the assets securing such borrowings.

For the three months endedMarch 31, 2017 and 2016, 2.0 million and 3.9 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive.

^(c)  Market-based awards and performance-based stock units (“PSUs”) are considered contingently issuable shares. Market-based awards and PSUs are included in the denominator for earnings per share if (i) the applicable market or performance condition(s) has been met and (ii) the inclusion of the market-based awards and PSUs are dilutive for the respective reporting periods. For the three months endedMarch 31, 2017 and 2016, 0.4 million and 1.0 million market-based awards and PSUs, respectively, were excluded from the calculation of diluted earnings per share because the market or performance conditions had not been met.

SEGMENT INFORMATION

Segment Reporting [Abstract]

SEGMENT INFORMATION

SEGMENT INFORMATION

The overall concept that IAC employs in determining its operating segments is to present the financial information in a manner consistent with: how the chief operating decision maker views the businesses; how the businesses are organized as to segment management; and the focus of the businesses with regards to the types of services or products offered or the target market. Operating segments are combined for reporting purposes if they meet certain aggregation criteria, which principally relate to the similarity of their economic characteristics or, in the case of the Other reportable segment, do not meet the quantitative thresholds that require presentation as separate operating segments.

________________________

^(a)  The Company's primary financial measure is Adjusted EBITDA, which is defined as operating income excluding: (1) stock-based compensation expense; (2) depreciation; and (3) acquisition-related items consisting of (i) amortization of intangible assets and impairments of goodwill and intangible assets, if applicable, and (ii) gains and losses recognized on changes in the fair value of contingent consideration arrangements. The Company believes this measure is useful for analysts and investors as this measure allows a more meaningful comparison between our performance and that of our competitors. Moreover, our management uses this measure internally to evaluate the performance of our business as a whole and our individual business segments, and this measure is one of the primary metrics by which our internal budgets are based and by which management is compensated. The above items are excluded from our Adjusted EBITDA measure because these items are non-cash in nature, and we believe that by excluding these items, Adjusted EBITDA corresponds more closely to the cash operating income generated from our business, from which capital investments are made and debt is serviced. Adjusted EBITDA has certain limitations in that it does not take into account the impact to IAC's statement of operations of certain expenses.

Loss Contingency [Abstract]

CONTINGENCIES

CONTINGENCIES

In the ordinary course of business, the Company is a party to various lawsuits. The Company establishes reserves for specific legal matters when it determines that the likelihood of an unfavorable outcome is probable and the loss is reasonably estimable. Management has also identified certain other legal matters where we believe an unfavorable outcome is not probable and, therefore, no reserve is established. Although management currently believes that resolving claims against us, including claims where an unfavorable outcome is reasonably possible, will not have a material impact on the liquidity, results of operations, or financial condition of the Company, these matters are subject to inherent uncertainties and management's view of these matters may change in the future. The Company also evaluates other contingent matters, including income and non-income tax contingencies, to assess the likelihood of an unfavorable outcome and estimated extent of potential loss. It is possible that an unfavorable outcome of one or more of these lawsuits or other contingencies could have a material impact on the liquidity, results of operations, or financial condition of the Company. See "Note 2—Income Taxes" for additional information related to income tax contingencies.

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

3 Months Ended

Mar. 31, 2017

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The Company prepares its consolidated financial statements in accordance with U.S. generally accepted accounting principles ("GAAP").

Basis of Consolidation and Accounting for Investments

Basis of Consolidation and Accounting for Investments

The consolidated financial statements include the accounts of the Company, all entities that are wholly-owned by the Company and all entities in which the Company has a controlling financial interest. Intercompany transactions and accounts have been eliminated.

Investments in the common stock or in-substance common stock of entities in which the Company has the ability to exercise significant influence over the operating and financial matters of the investee, but does not have a controlling financial interest, are accounted for using the equity method and are included in "Long-term investments" in the accompanying consolidated balance sheet.

The accompanying unaudited consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation. Interim results are not necessarily indicative of the results that may be expected for the full year. The accompanying unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016.

Accounting Estimates

Accounting Estimates

Management of the Company is required to make certain estimates, judgments and assumptions during the preparation of its consolidated financial statements in accordance with GAAP. These estimates, judgments and assumptions impact the reported amounts of assets, liabilities, revenue and expenses and the related disclosure of contingent assets and liabilities. Actual results could differ from these estimates.

On an ongoing basis, the Company evaluates its estimates and judgments including those related to: the fair values of marketable securities and other investments; the recoverability of goodwill and indefinite-lived intangible assets; the useful lives and recoverability of definite-lived intangible assets and property and equipment; the carrying value of accounts receivable, including the determination of the allowance for doubtful accounts; the determination of revenue reserves; the fair value of acquisition-related contingent consideration arrangements; the liabilities for uncertain tax positions; the valuation allowance for deferred income tax assets; and the fair value of and forfeiture rates for stock-based awards, among others. The Company bases its estimates and judgments on historical experience, its forecasts and budgets and other factors that the Company considers relevant.

Certain Risks and Concentrations

Certain Risks and Concentrations

A significant portion of the Company's revenue is derived from online advertising, the market for which is highly competitive and rapidly changing. Significant changes in this industry or changes in advertising spending behavior or in customer buying behavior could adversely affect our operating results. Most of the Company's online advertising revenue is attributable to a services agreement with Google Inc. ("Google"). For the three months ended March 31, 2017 and 2016, revenue from Google represents 25% and 35%, respectively, of the Company's consolidated revenue. The Company's services agreement became effective on April 1, 2016, following the expiration of the previous services agreement. The services agreement expires on March 31, 2020; however, the Company may choose to terminate the agreement effective March 31, 2019. The services agreement requires that we comply with certain guidelines promulgated by Google. Google may generally unilaterally update its policies and guidelines without advance notice, which could in turn require modifications to, or prohibit and/or render obsolete certain of our products, services and/or business practices, which could be costly to address or otherwise have an adverse effect on our business, financial condition and results of operations.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Accounting Pronouncements not yet adopted by the Company

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers, which clarifies the principles for recognizing revenue and develops a common standard for all industries. ASU 2014-09 was subsequently amended during 2015 and 2016; these amendments provide further revenue recognition guidance related to principal versus agent considerations, performance obligations and licensing, and narrow-scope improvements and practical expedients.

ASU No. 2014-09 is a comprehensive revenue recognition standard that will supersede nearly all existing revenue recognition guidance under GAAP. The new standard provides a single principles-based, five-step model to be applied to all contracts with customers. This five-step model includes (1) identifying the contract(s) with the customer, (2) identifying the performance obligations in the contract, (3) determining the transaction price, (4) allocating the transaction price to the performance obligations in the contract and (5) recognizing revenue when each performance obligation is satisfied. More specifically, revenue will be recognized when promised goods or services are transferred to the customer in an amount that reflects the consideration expected in exchange for those goods or services. ASU No. 2014-09 is effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption permitted for interim and annual reporting periods beginning after December 15, 2016. Upon adoption, ASU No. 2014-09 may either be applied retrospectively to each prior period presented or using the modified retrospective approach with the cumulative effect recognized as of the date of initial application.

While the Company’s evaluation of the impact the adoption of ASU No. 2014-09 on its consolidated financial statements continues, it has progressed to the point where we have reached certain preliminary determinations. The Company does not expect the adoption of ASU No. 2014-09 to have a material effect on its consolidated financial statements. The Company will adopt ASU No. 2014-09 using the modified retrospective approach effective January 1, 2018. Therefore, the cumulative effect of adoption will be reflected as an adjustment to beginning retained earnings in the Form 10-Q for the period ending March 31, 2018. The adoption of ASU No. 2014-09 will primarily affect the Company’s HomeAdvisor and Applications segments. The effect on HomeAdvisor will be that sales commissions, which represent the incremental direct costs of obtaining a service professional contract, will be capitalized and amortized over the average life of a service professional. These costs are expensed as incurred today. Within Applications, the primary effect will be to accelerate the recognition of the portion of the revenue of certain desktop applications sold by SlimWare that qualify as functional intellectual property under ASU No. 2014-09. This revenue is currently deferred and recognized over the applicable subscription term.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which supersedes existing guidance on accounting for leases in "Leases (Topic 840)" and generally requires all leases to be recognized in the statement of financial position. The provisions of ASU No. 2016-02 are effective for reporting periods beginning after December 15, 2018; early adoption is permitted. The provisions of ASU No. 2016-02 are to be applied using a modified retrospective approach. The Company is currently evaluating the impact the adoption of this standard update will have on its consolidated financial statements.

Accounting Pronouncements adopted by the Company

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which clarifies how cash receipts and cash payments in certain transactions are presented and classified on the statement of cash flows. The provisions of ASU No. 2016-15 are effective for reporting periods beginning after December 15, 2017, including interim periods, and will require adoption on a retrospective basis unless it is impracticable to apply, in which case we would be required to apply the amendments prospectively as of the earliest date practicable; early adoption is permitted. Upon adoption, cash payments not made soon after the acquisition date of a business combination to settle a contingent consideration liability are separated and classified as cash outflows for operating activities and financing activities. Cash payments up to the amount of the contingent consideration liability recognized at the acquisition date (including measurement-period adjustments) are classified as financing activities; any excess is classified as operating activities. Cash payments made soon after the acquisition date of a business combination by an acquirer to settle a contingent consideration liability are classified as cash outflows for investing activities. The Company early adopted the provisions of ASU No. 2016-15 on January 1, 2017. As a result of the adoption of ASU No. 2016-15, $11.1 million of acquisition-related contingent consideration payments for the three months ended March 31, 2017 was in excess of the liability recognized at the acquisition date and, therefore, has been classified as a cash outflow in "Other adjustments, net" within net cash provided by operating activities in the accompanying consolidated statement of cash flows.

In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The Company adopted the provisions of ASU No. 2016-09 on January 1, 2017. Excess tax benefits or deficiencies related to equity awards to employees upon exercise of stock options and the vesting of restricted stock units after January 1, 2017 are (i) reflected in the consolidated statement of operations as a component of the provision for income taxes, rather than recognized in equity, and (ii) reflected as operating, rather than financing, cash flows in our consolidated statement of cash flows. Excess tax benefits for the three months ended March 31, 2017 were $26.8 million. Excess tax benefits of $15.3 million for the three months ended March 31, 2016 were reclassified in the consolidated statement of cash flows to conform to the current year presentation. Upon adoption, the calculation of fully diluted shares excludes excess tax benefits from the assumed proceeds in applying the treasury stock method, they previously were included in the calculation; this change increased fully diluted shares by approximately 1.3 million shares for the three months ended March 31, 2017. The Company continues to account for forfeitures using an estimated forfeiture rate.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which is intended to simplify the accounting for goodwill impairment. The guidance eliminates the requirement to calculate the implied fair value of goodwill under today’s two-step impairment test to measure a goodwill impairment charge. The provisions of ASU No. 2017-04 are effective for reporting periods beginning after December 15, 2019; early adoption is permitted. The provisions of ASU No. 2017-04 are to be applied using a prospective approach. The Company early adopted the provisions of ASU No. 2017-04 on January 1, 2017 and the adoption of this standard update did not have a material impact on its consolidated financial statements.

^(a)  Represents the impact on earnings related to Match Group's dilutive securities under the if-converted method.

^(b)  If the effect is dilutive, weighted average common shares outstanding include the incremental shares that would be issued upon the assumed exercise of subsidiary denominated equity, stock options and vesting of restricted stock units ("RSUs"). For the three months endedMarch 31, 2017 and 2016, 2.0 million and 3.9 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive.

^(c)  Market-based awards and performance-based stock units (“PSUs”) are considered contingently issuable shares. Market-based awards and PSUs are included in the denominator for earnings per share if (i) the applicable market or performance condition(s) has been met and (ii) the inclusion of the market-based awards and PSUs are dilutive for the respective reporting periods. For the three months endedMarch 31, 2017 and 2016, 0.4 million and 1.0 million market-based awards and PSUs, respectively, were excluded from the calculation of diluted earnings per share because the market or performance conditions had not been met.

________________________

^(a)  The Company's primary financial measure is Adjusted EBITDA, which is defined as operating income excluding: (1) stock-based compensation expense; (2) depreciation; and (3) acquisition-related items consisting of (i) amortization of intangible assets and impairments of goodwill and intangible assets, if applicable, and (ii) gains and losses recognized on changes in the fair value of contingent consideration arrangements. The Company believes this measure is useful for analysts and investors as this measure allows a more meaningful comparison between our performance and that of our competitors. Moreover, our management uses this measure internally to evaluate the performance of our business as a whole and our individual business segments, and this measure is one of the primary metrics by which our internal budgets are based and by which management is compensated. The above items are excluded from our Adjusted EBITDA measure because these items are non-cash in nature, and we believe that by excluding these items, Adjusted EBITDA corresponds more closely to the cash operating income generated from our business, from which capital investments are made and debt is serviced. Adjusted EBITDA has certain limitations in that it does not take into account the impact to IAC's statement of operations of certain expenses.
