THE COMPANY AND SUMMARY OF SIGN

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	6 Months Ended
	Jun. 30, 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 moved the non-dating business to its “Other” segment effective March 31, 2017 and prior period segment data has been recast to conform to this presentation. On May 1, 2017, the Company announced that it had entered into a definitive agreement with Angie's List, Inc. ("Angie's List") to combine the businesses in the Company's HomeAdvisor segment and Angie’s List under a new publicly traded company to be called ANGI Homeservices Inc. IAC will own between approximately 87% and 90% of the economic interest (on a fully diluted basis) and approximately 98% of the total voting power of ANGI Homeservices Inc. common stock. This transaction is subject to the satisfaction of customary closing conditions, including the approval by Angie's List stockholders, and is expected to close in the fourth quarter of 2017. 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 for the year ended December 31, 2016 included in the Company's Current Report on Form 8-K dated July 18, 2017. 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. 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. Actual results could differ from these estimates. Certain Risks and Concentrations A meaningful 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 and six months ended June 30, 2017 , revenue from Google represents 23% and 24% , respectively, of the Company's consolidated revenue. For the three and six months ended June 30, 2016, revenue from Google represents 24% and 30% , 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 and six months ended June 30, 2017 , revenue earned from Google was $174.6 million and $362.4 million , respectively. For the three and six months ended June 30, 2016, revenue earned from Google was $181.5 million and $466.2 million , respectively. This revenue is earned by the businesses comprising the Applications and Publishing segments. For both the three and six months ended June 30, 2017 , revenue earned from Google represents 83% of Applications revenue and 70% of Publishing revenue. For the three and six months ended June 30, 2016, revenue earned from Google represents 85% and 88% of Applications revenue and 69% and 78% of Publishing revenue, respectively. Accounts receivable related to revenue earned from Google totaled $65.9 million and $65.8 million at June 30, 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 No. 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. In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting , which provides guidance about the changes to the terms and conditions of a share-based payment award that require an entity to apply modification accounting in "Stock Compensation (Topic 718)." The provisions of ASU No. 2017-09 are effective for reporting periods beginning after December 15, 2017; early adoption is permitted. The provisions of ASU No. 2017-09 are to be applied prospectively to an award modified on or after the adoption date. The Company does not expect the adoption of this standard update to have a material impact on its consolidated financial statements and is currently evaluating the timing of adoption. 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 made soon after the acquisition date of a business to settle a contingent consideration liability are classified as cash outflows for investing activities. Cash payments which are not made soon after the acquisition date of a business to settle a contingent consideration liability are separated and classified as cash outflows for financing activities up to the amount of the contingent consideration liability recognized at the acquisition date and as cash outflows from operating activities for any excess. The Company early adopted the provisions of ASU No. 2016-15 on January 1, 2017. As a result, $11.1 million of an acquisition-related contingent consideration payment of $15.0 million , which was in excess of the liability initially recognized at the acquisition date, has been classified as a cash outflow within net cash provided by operating activities in the accompanying consolidated statement of cash flows for the six months ended June 30, 2017. 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 the 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 six months ended June 30, 2017 were $57.3 million . Excess tax benefits of $21.9 million for the six months ended June 30, 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; previously such benefits were included in the calculation. This change increased fully diluted shares by approximately 1.5 million and 1.4 million shares for the three and six months ended June 30, 2017 , respectively. 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 TAXES	6 Months Ended
	Jun. 30, 2017
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 and six months ended June 30, 2017 , the Company recorded an income tax benefit of $19.4 million and $43.3 million , respectively. The income tax benefit for the three and six months ended June 30, 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 $57.3 million for the six months ended June 30, 2017 are recognized as a reduction to the income tax provision rather than as an increase to additional paid-in capital. For the three and six months ended June 30, 2016, the Company recorded an income tax benefit for continuing operations of $96.7 million and $95.2 million , respectively, which, in each case, represents an effective income tax rate of 34% . The effective tax rate each period is lower than the statutory rate of 35% due primarily to the non-deductible portion of the goodwill impairment at the Publishing segment, partially offset by state taxes. The Company recognizes interest and, if applicable, penalties related to unrecognized tax benefits in the income tax provision. At June 30, 2017 and December 31, 2016 , the Company has accrued $3.0 million and $2.6 million , respectively, for the payment of interest. At both June 30, 2017 and December 31, 2016 , the Company has accrued $1.7 million 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 June 30, 2018. 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 June 30, 2017 and December 31, 2016 , unrecognized tax benefits, including interest and penalties, are $41.4 million and $41.0 million , respectively. If unrecognized tax benefits at June 30, 2017 are subsequently recognized, $38.0 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 $2.6 million by June 30, 2018, due to expirations of statutes of limitations; $2.4 million of which would reduce the income tax provision.

FAIR VALUE MEASUREMENTS AND FIN

FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS	6 Months Ended
	Jun. 30, 2017
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. • 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: June 30, 2017 Quoted Market Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Fair Value Measurements (In thousands) Assets: Cash equivalents: Money market funds $ 794,630 $ — $ — $ 794,630 Commercial paper — 187,380 — 187,380 Time deposits — 105,596 — 105,596 Treasury discount notes 49,974 — — 49,974 Marketable securities: Commercial paper — 14,984 — 14,984 Total $ 844,604 $ 307,960 $ — 1,152,564 Liabilities: Contingent consideration arrangements $ — $ — $ (24,829 ) $ (24,829 ) December 31, 2016 Quoted Market Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Fair Value Measurements (In thousands) Assets: Cash equivalents: Money market funds $ 667,662 $ — $ — $ 667,662 Commercial paper — 123,640 — 123,640 Time deposits — 79,000 — 79,000 Treasury discount notes 24,991 — — 24,991 Marketable securities: Commercial paper — 49,797 — 49,797 Treasury discount notes 34,974 — — 34,974 Corporate debt securities — 4,571 — 4,571 Total $ 727,627 $ 257,008 $ — $ 984,635 Liabilities: Contingent consideration arrangements $ — $ — $ (33,871 ) $ (33,871 ) The following tables present the changes in the Company's financial instruments that are measured at fair value on a recurring basis using significant unobservable inputs (Level 3): Contingent Consideration Arrangements Three Months Ended June 30, 2017 2016 (In thousands) Balance at April 1 $ (21,821 ) $ (37,243 ) Total net (losses) gains: Included in earnings: Fair value adjustments (2,994 ) (6,801 ) Included in other comprehensive loss (14 ) (3,375 ) Fair value at date of acquisition — 55 Settlements — 1,838 Balance at June 30 $ (24,829 ) $ (45,526 ) Six Months Ended June 30, 2017 2016 Contingent Consideration Arrangements Auction Rate Security Contingent Consideration Arrangements (In thousands) Balance at January 1 $ (33,871 ) $ 4,050 $ (33,873 ) Total net (losses) gains: Included in earnings: Fair value adjustments (4,885 ) — (10,470 ) Included in other comprehensive (loss) income (1,073 ) 5,950 (5,281 ) Fair value at date of acquisition — — 1,948 Settlements 15,000 — 2,150 Proceeds from sale — (10,000 ) — Balance at June 30 $ (24,829 ) $ — $ (45,526 ) Contingent Consideration Arrangements As of June 30, 2017 , there are four contingent consideration arrangements related to business acquisitions. The maximum contingent payments related to these four arrangements are $91.2 million and the fair value of these arrangements at June 30, 2017 is $24.8 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 initially 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 June 30, 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 June 30, 2017 and December 31, 2016 includes a current portion of $23.7 million and $33.4 million , respectively, and a non-current portion of $1.1 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 June 30, 2017 and December 31, 2016 , the carrying values of the Company's investments accounted for under the cost method totaled $115.2 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: June 30, 2017 December 31, 2016 Carrying Fair Carrying Fair (In thousands) Current portion of long-term debt $ — $ — $ (20,000 ) $ (20,311 ) Long-term debt, net of current portion (1,572,994 ) (1,657,758 ) (1,582,484 ) (1,657,861 ) 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.

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 June 30, 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 June 30, 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 June 30, 2017 is 4.37% . 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 June 30, 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 subsidiaries. For the six months ended June 30, 2017 , the Company redeemed and repurchased $28.3 million of its 2013 Senior Notes and repurchased $3.3 million of its 2012 Senior Notes. For the six months ended June 30, 2016 , the Company redeemed and repurchased $55.0 million of its 2013 Senior Notes and repurchased $6.1 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 June 30, 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 June 30, 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 and six months ended June 30, 2016, the effect of Match Group's dilutive securities under the if-converted method is excluded because it would have been anti-dilutive due to the Company's net loss. (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 and stock options and vesting of restricted stock units ("RSUs"). For the three and six months ended June 30, 2017 , less than 0.1 million and 0.5 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive. (c) For the three and six months ended June 30, 2016, the Company had a loss from operations and, as a result, approximately 9.8 million potentially dilutive securities were excluded from computing diluted earnings per share because the impact would have been anti-dilutive. (d) Market-based awards and performance-based stock units (“PSUs”) are considered contingently issuable shares. Shares issuable upon exercise or vesting of 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 is dilutive for the respective reporting periods. For both the three and six months ended June 30, 2017 , 0.4 million shares underlying market-based awards and PSUs were excluded from the calculation of diluted earnings per share because the market or performance conditions had not been met. For both the three and six months ended June 30, 2016, 1.0 million shares underlying market-based awards and PSUs were excluded from the calculation of diluted earnings per share because the market or performance conditions had not been met.

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.

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.

CONTINGENCIES

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 SI20

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 30, 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 for the year ended December 31, 2016 included in the Company's Current Report on Form 8-K dated July 18, 2017.
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. 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. Actual results could differ from these estimates.
Certain Risks and Concentrations	Certain Risks and Concentrations A meaningful 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 and six months ended June 30, 2017 , revenue from Google represents 23% and 24% , respectively, of the Company's consolidated revenue. For the three and six months ended June 30, 2016, revenue from Google represents 24% and 30% , 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 No. 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. In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting , which provides guidance about the changes to the terms and conditions of a share-based payment award that require an entity to apply modification accounting in "Stock Compensation (Topic 718)." The provisions of ASU No. 2017-09 are effective for reporting periods beginning after December 15, 2017; early adoption is permitted. The provisions of ASU No. 2017-09 are to be applied prospectively to an award modified on or after the adoption date. The Company does not expect the adoption of this standard update to have a material impact on its consolidated financial statements and is currently evaluating the timing of adoption. 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 made soon after the acquisition date of a business to settle a contingent consideration liability are classified as cash outflows for investing activities. Cash payments which are not made soon after the acquisition date of a business to settle a contingent consideration liability are separated and classified as cash outflows for financing activities up to the amount of the contingent consideration liability recognized at the acquisition date and as cash outflows from operating activities for any excess. The Company early adopted the provisions of ASU No. 2016-15 on January 1, 2017. As a result, $11.1 million of an acquisition-related contingent consideration payment of $15.0 million , which was in excess of the liability initially recognized at the acquisition date, has been classified as a cash outflow within net cash provided by operating activities in the accompanying consolidated statement of cash flows for the six months ended June 30, 2017. 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 the 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 six months ended June 30, 2017 were $57.3 million . Excess tax benefits of $21.9 million for the six months ended June 30, 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; previously such benefits were included in the calculation. This change increased fully diluted shares by approximately 1.5 million and 1.4 million shares for the three and six months ended June 30, 2017 , respectively. 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.

For the three and six months ended June 30, 2016, the effect of Match Group's dilutive securities under the if-converted method is excluded because it would have been anti-dilutive due to the Company's net loss. (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 and stock options and vesting of restricted stock units ("RSUs"). For the three and six months ended June 30, 2017 , less than 0.1 million and 0.5 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive. (c) For the three and six months ended June 30, 2016, the Company had a loss from operations and, as a result, approximately 9.8 million potentially dilutive securities were excluded from computing diluted earnings per share because the impact would have been anti-dilutive. (d) Market-based awards and performance-based stock units (“PSUs”) are considered contingently issuable shares. Shares issuable upon exercise or vesting of 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 is dilutive for the respective reporting periods. For both the three and six months ended June 30, 2017 , 0.4 million shares underlying market-based awards and PSUs were excluded from the calculation of diluted earnings per share because the market or performance conditions had not been met. For both the three and six months ended June 30, 2016, 1.0 million shares underlying market-based awards and PSUs were excluded from the calculation of diluted earnings per share because the market or performance conditions had not been met.

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.
