THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	6 Months Ended
	Jun. 30, 2016
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 some of the world's most recognized brands and products, such as HomeAdvisor, Vimeo, About.com, Dictionary.com, The Daily Beast, Investopedia, and Match Group's online dating portfolio, which includes Match, OkCupid, Tinder and PlentyOfFish. All references to "IAC," the "Company," "we," "our" or "us" in this report are to IAC/InterActiveCorp. 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, 2015. 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 those 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 substantial 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"). The Company's service agreement became effective on April 1, 2016, following the expiration of the previous services agreement. This services agreement expires on March 31, 2020; the Company may choose to terminate the agreement effective March 31, 2019. This services agreement requires that we comply with certain guidelines promulgated by Google. Google may generally unilaterally update its own 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, 2016, revenue earned from Google was $181.5 million and $466.2 million, respectively. For the three and six months ended June 30, 2015, revenue earned from Google was $308.2 million and $647.8 million, respectively. This revenue is earned by the businesses comprising the Publishing and Applications segments. For the three and six months ended June 30, 2016, revenue earned from Google represents 69% and 78% of Publishing revenue and 85% and 88% of Applications revenue, respectively. For the three and six months ended June 30, 2015, revenue earned from Google represents 82% and 83% of Publishing revenue and 94% and 94% of Applications revenue, respectively. Accounts receivable related to revenue earned from Google totaled $57.2 million and $97.2 million at June 30, 2016 and December 31, 2015, respectively. Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2016-09, Improvements to Employee Share-Based Payments Accounting (Topic 718). The update is intended to simplify existing guidance on various aspects of the accounting and presentation of employee share-based payments in financial statements including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification on the statement of cash flows. The provisions of ASU 2016-09 are effective for reporting periods beginning after December 15, 2016; early adoption is permitted. The Company is currently evaluating the impact the adoption of this standard update will have on its consolidated financial statements. 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 2016-02 are effective for reporting periods beginning after December 15, 2018; early adoption is permitted. The provisions of ASU 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 April 2015, the FASB issued ASU No. 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, and in August 2015, the FASB issued ASU 2015-15, Interest-Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. Together, this guidance requires that deferred debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the associated debt liability, while debt issuance costs related to line-of-credit arrangements may still continue to be classified as assets. The Company adopted the provisions of ASU 2015-03 and ASU 2015-15 in the first quarter of 2016 and applied the provisions retrospectively, resulting in $21.3 million of deferred debt issuance costs being reclassified from other non-current assets to long-term debt, net of current portion, in the accompanying December 31, 2015 consolidated balance sheet. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which clarifies the principles for recognizing revenue and develops a common standard for all industries. In July 2015, the FASB decided to defer the effective date for annual reporting periods beginning after December 15, 2017. In March, April and May 2016, the FASB issued ASU 2016-08, ASU 2016-10 and ASU 2016-12, respectively, which provide further revenue recognition guidance related to principal versus agent considerations, performance obligations and licensing, and narrow-scope improvements and practical expedients. Early adoption is permitted beginning on the original effective date of December 15, 2016. Upon adoption, ASU 2014-09 may either be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. The Company is currently evaluating the impact the adoption of this standard update will have on its consolidated financial statements, and the method and timing of adoption. Reallocation of Noncontrolling Interests During the quarter ended March 31, 2016, the Company reallocated amounts within the accounts comprising shareholders' equity to correct the amount of noncontrolling interests that was initially recorded following the initial public offering ("IPO") of Match Group, which occurred on November 24, 2015. The noncontrolling interests should have been recorded using the net book value of Match Group rather than the net IPO proceeds. In addition, the adjustment allocates the proportionate share of the accumulated other comprehensive loss to the noncontrolling interests balance. The reallocation has no effect on net income or earnings per share. Based on our assessment of both qualitative and quantitative factors, the reallocation was not considered material to the consolidated financial statements of the Company as of and for: (i) the year ended December 31, 2015, (ii) the three months ended March 31, 2016; and (iii) the six months ended June 30, 2016. Therefore, the adjustment was initially reflected in the consolidated financial statements of the Company as of and for the three months ended March 31, 2016 and will, therefore, also be reflected in the year-to-date consolidated financial statements of each subsequent interim period in 2016 and the annual consolidated financial statements for the year ending December 31, 2016. Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation.

INCOME TAXES	6 Months Ended
INCOME TAXES	Jun. 30, 2016
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, 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. For the three and six months ended June 30, 2015, the Company recorded an income tax benefit for continuing operations of $12.0 million and $5.8 million, respectively. The income tax benefit for each period is due primarily to the realization of certain deferred tax assets, a reduction in tax reserves and related interest due to the expiration of statutes of limitations, and the non-taxable gain on contingent consideration fair value adjustments, 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, 2016 and December 31, 2015, the Company has accrued $2.8 million and $2.5 million, respectively, for the payment of interest. At June 30, 2016 and December 31, 2015, the Company has accrued $1.9 million and $2.2 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 has substantially completed its audit of 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 March 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 June 30, 2016 and December 31, 2015, unrecognized tax benefits, including interest, are $42.4 million and $43.4 million, respectively. If unrecognized tax benefits at June 30, 2016 are subsequently recognized, $39.4 million, net of related deferred tax assets and interest, would reduce the income tax provision for continuing operations. The comparable amount as of December 31, 2015 was $41.0 million. The Company believes that it is reasonably possible that its unrecognized tax benefits could decrease by $10.6 million within twelve months of June 30, 2016, primarily due to expirations of statutes of limitations; $10.2 million of which would reduce the income tax provision for continuing operations.

BUSINESS COMBINATION

Business Combinations [Abstract]

BUSINESS COMBINATION

On October 28, 2015, Match Group completed the acquisition of Plentyoffish Media Inc. ("PlentyOfFish"), a leading provider of subscription-based and ad-supported online personals servicing North America, Europe, Latin America and Australia. Services are provided through websites and mobile applications that PlentyOfFish owns and operates. The purchase price was $574.1 million in cash and is net of a $0.9 million working capital adjustment paid to Match Group in the second quarter of 2016. The financial results of PlentyOfFish are included in the Company's consolidated financial statements, within the Match Group segment, beginning October 28, 2015.

The table below summarizes the fair values of the assets acquired and liabilities assumed at the date of acquisition:



	(In thousands)
Cash and cash equivalents	$	4,626
Other current assets	4,460
Computer and other equipment	2,990
Goodwill	488,644
Intangible assets	84,100
Other non-current assets	1,073
Total assets	585,893
Current liabilities	(6,418		)
Other long-term liabilities	(5,325		)
Net assets acquired	$	574,150

The purchase price was based on the expected financial performance of PlentyOfFish, not on the value of the net identifiable assets at the time of acquisition, which resulted in a significant portion of the purchase price being attributed to goodwill. The expected financial performance of PlentyOfFish reflects that it is complementary and synergistic to the existing Match Group dating businesses.

Intangible assets are as follows:



	(In thousands)		Weighted-Average Useful Life (Years)
Indefinite-lived trade name	$	66,300	Indefinite
Customer relationships	10,100		Less than 1
New registrants	3,100		Less than 1
Non-compete agreement	3,000		5
Developed technology	1,600		2
Total intangible assets acquired	$	84,100

PlentyOfFish's other current assets, property and equipment, other non-current assets, current liabilities and other long-term liabilities were reviewed and adjusted to their fair values at the date of acquisition, as necessary. The fair values of trade names, customer relationships and the non-compete agreement were determined using variations of the income approach; specifically, in respective order, the relief from royalty, excess earnings and with or without methodologies. The fair values of new registrants and developed technology were determined using a cost approach that utilized the cost to replace methodology. The valuations of the intangible assets incorporate significant unobservable inputs and require significant judgment and estimates, including the amount and timing of future cash flows and the determination of royalty and discount rates. The amount attributed to goodwill is not tax deductible.

Pro forma Financial Information

The unaudited pro forma financial information in the table below presents the combined results of the Company and PlentyOfFish as if the acquisition of PlentyOfFish had occurred on January 1, 2015. The pro forma financial information includes adjustments required under the acquisition method of accounting and is presented for informational purposes only and is not necessarily indicative of what the results would have been had the acquisition actually occurred on January 1, 2015. For the three and six months ended June 30, 2015, pro forma adjustments reflected below include decreases to revenue of $1.7 million and $8.3 million, respectively, related to the write-off of deferred revenue at the date of acquisition and increases of $5.2 million and $9.0 million, respectively, in amortization of intangible assets.



	Three Months Ended June 30, 2015		Six Months Ended June 30, 2015
	(In thousands, except per share data)
Revenue	$	790,486	$	1,575,155

The June 30, 2016 goodwill balance includes accumulated impairment losses of $598.0 million, $529.1 million, $11.6 million and $42.1 million at Publishing, Applications, Connected Ventures (included in the Video segment), and ShoeBuy (included in the Other segment), respectively.

The additions primarily relate to the acquisition of VHX (included in the Video segment). The deductions primarily relate to the sale of PriceRunner (included in the Other segment).

The Company performs its annual impairment assessment of goodwill and indefinite-lived intangible assets as of October 1. In each reporting period, the Company assesses whether any events have occurred or circumstances have changed that would make it more likely than not that the carrying values of its reporting units and indefinite-lived intangible assets are in excess of their respective fair values. If the Company so concludes, the Company updates its estimate of the fair value of the applicable reporting unit and/or indefinite-lived intangible asset. If the estimated fair value of a reporting unit exceeds its carrying value, goodwill of the reporting unit is not impaired and the second step of the impairment test is not necessary. If the carrying value of a reporting unit exceeds its estimated fair value, then the second step of the goodwill impairment test must be performed. The second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with its carrying value to measure the amount of impairment, if any. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. In other words, the estimated fair value of the reporting unit is allocated to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination and the fair value of the reporting unit was the purchase price paid. If the carrying value of the reporting unit's goodwill exceeds the implied fair value of that goodwill, an impairment is recognized in an amount equal to the excess. Similarly, if the carrying value of an indefinite-lived intangible asset exceeds its fair value, an impairment is recorded equal to the excess.

The Company concluded that it was more likely than not that the carrying value of the Publishing reporting unit and its indefinite-lived intangible assets were in excess of their respective fair values as of June 30, 2016 and, therefore, updated its estimated fair values of these assets as of that date. This conclusion was based upon the impact of new Google contract, traffic trends and monetization challenges and the anticipated corresponding impact on our estimate of fair value. In performing the first step of the goodwill impairment assessment, the Company determined the fair value of the Publishing reporting unit using both an income approach based on discounted cash flows ("DCF") and a market approach. Determining fair value using a DCF analysis requires the exercise of significant judgment with respect to several items, including judgment about the amount and timing of expected future cash flows and appropriate discount rates. The expected cash flows used in the Publishing DCF analysis were based on the Company's most recent forecast for the second half of 2016 and each of the years in the forecast period, which were updated to include the effects of the new Google contract, traffic trends and monetization challenges and the cost savings from our restructuring efforts. For years beyond the forecast period, the Company's estimated cash flows were based on forecasted growth rates. The discount rate used in the DCF analysis reflects the risks inherent in the expected future cash flows of the Publishing reporting unit. Determining fair value using a market approach considers multiples of financial metrics based on both acquisitions and trading multiples of a selected peer group of companies. From the comparable companies, a representative market multiple was determined which was applied to financial metrics to estimate the fair value of the Publishing reporting unit. To determine a peer group of companies for Publishing, we considered companies relevant in terms of consumer use, monetization model, margin and growth characteristics and brand strength operating in their respective sectors.

The second step of the impairment calculation is to determine the fair value of the goodwill of the Publishing reporting unit. The estimated fair value of the Publishing reporting unit was allocated to all of its assets and liabilities (which included unrecognized intangible assets) as if the Publishing reporting unit had been acquired in a business combination on June 30, 2016 and the fair value of the reporting unit was the purchase price paid. Publishing's other current assets, property and equipment, other non-current assets, current liabilities and other long-term liabilities were reviewed and adjusted to their fair values at June 30, 2016 as necessary. The fair values of trade names, advertiser relationships, and certain existing content at About.com were determined using variations of the income approach; specifically, in respective order, the relief from royalty, with or without and excess earnings methodologies. The fair values of developed technology and certain existing content at Investopedia were determined using a cost approach that utilized the cost to replace methodology. The valuations of the intangible assets incorporate significant unobservable inputs and require significant judgment and estimates, including the amount and timing of future cash flows and the determination of royalty and discount rates. The fair value of the goodwill of the Publishing reporting unit was determined to be zero and an impairment of the entire goodwill balance of $275.4 million was recognized in the second quarter of 2016. The goodwill impairment charge is a preliminary estimate that will be finalized in the third quarter of 2016.

The Company also recorded impairments of $11.6 million of certain trade names and trademarks in the second quarter of 2016. The impairments were due to reduced level of revenue and profits, which, in turn, also led to a reduction in the assumed royalty rates for these assets. The royalty rates used to value the trade names that were impaired ranged from 2% to 6% and the discount rate that was used reflects the risks inherent in the expected future cash flows of the trade names and trademarks.

The following table presents the balance of goodwill by reportable segment, including the changes in the carrying value of goodwill, for the year ended December 31, 2015:

________________________

^(a) Prior to the fourth quarter of 2015, Search & Applications was a reportable segment consisting of one operating segment and one reporting unit. In the fourth quarter of 2015, Search &Applications was split into three new operating segments and reporting units: Publishing, Applications and PriceRunner (included in the Other segment). The goodwill of Search & Applications was allocated to these three reporting units based upon their relative fair values as of October 1, 2015. It is not possible to reflect this allocation on a retrospective basis because of acquisitions and dispositions during the three years in the period ended December 31, 2015.

The additions primarily relate to Match Group's acquisitions of PlentyOfFish and Eureka. The goodwill impairment charge at ShoeBuy (included in the Other segment) was due to increased investment and the seasonal effect of high inventory levels as of October 1, 2015.

The December 31, 2015 goodwill balance includes accumulated impairment losses of $322.6 million, $529.1 million and $65.2 million, which were re-allocated from the former Search & Applications segment, to Publishing, Applications and PriceRunner (included in the Other segment), respectively, based on their relative fair values as of October 1, 2015 following the change in reportable segments that occurred during the fourth quarter of 2015. The goodwill balance at December 31, 2015 also includes accumulated impairment losses of $11.6 million and $42.1 million at Connected Ventures (included in the Video segment) and ShoeBuy (included in the Other segment), respectively.

Intangible assets with indefinite lives are trade names and trademarks acquired in various acquisitions. During the second quarter of 2016, the Company changed the classification of certain intangibles from indefinite-lived to definite-lived at Publishing. In addition, in connection with the goodwill impairment charge at Publishing described above, the Company recorded an $11.6 million impairment charge on certain indefinite-lived trade names. The impairment charge is included in "Amortization of intangibles" in the accompanying consolidated statement of operations. At June 30, 2016 and December 31, 2015, intangible assets with definite lives are as follows:

The unrealized gains and losses in the tables above are included in "Accumulated other comprehensive loss" in the accompanying consolidated balance sheet. 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 June 30, 2016, and it is not more likely than not that the Company will be required to sell these securities before recovery of their amortized cost bases, which may be maturity. The aggregate fair value of available-for-sale marketable debt securities with unrealized losses is $17.3 million as of June 30, 2016. There is one investment in current available-for-sale marketable debt securities that has been in a continuous unrealized loss position for longer than twelve months as of June 30, 2016.

FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS

Jun. 30, 2016

Fair Value Disclosures [Abstract]

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 June 30, 2016, there are eight contingent consideration arrangements related to business acquisitions. Seven of the contingent consideration arrangements have limits as to the maximum amount that can be paid; the maximum contingent payments related to these arrangements are $141.8 million and the fair value of these arrangements at June 30, 2016 is $45.4 million. The fair value of the one contingent consideration arrangement without a limit on the maximum amount is $0.1 million at June 30, 2016.

The contingent consideration arrangements are generally based upon earnings performance and/or operating metrics such as monthly active users. 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 June 30, 2016 reflect discount rates ranging from 12% to 25%.

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, 2016 and December 31, 2015 includes a current portion of $10.8 million and $2.6 million, respectively, and non-current portion of $34.7 million and $31.2 million, respectively, which are included in “Accrued expenses and other current liabilities” and “Other long-term liabilities,” respectively, in the accompanying consolidated balance sheet.

Marketable equity security

The cost basis of the Company's long-term marketable equity security at December 31, 2015 was $5.0 million, with gross unrealized gains of $2.6 million. The gross unrealized gains at December 31, 2015 was included in "Accumulated other comprehensive loss" in the accompanying consolidated balance sheet. During the second quarter of 2016 this marketable equity security was classified as short-term due to the Company's decision to sell this security.

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. See Note 4 for additional information on the Publishing goodwill and indefinite-lived intangible asset impairment charges.

Cost method investments

At June 30, 2016 and December 31, 2015, the carrying values of the Company's investments accounted for under the cost method totaled $116.5 million and $114.5 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, 2016						December 31, 2015
	Carrying Value			Fair Value			Carrying Value			Fair Value

Current portion of long-term debt	$	(50,000	)	$	(52,025	)	$	(40,000	)	$	(39,850	)
Long-term debt, net of current portion	(1,655,259		)	(1,722,286		)	(1,726,954		)	(1,761,601		)

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 repay 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 the redemption prices set forth below, together with accrued and unpaid interest thereon to the applicable redemption date, if redeemed during the twelve-month period beginning on June 1 of the years indicated below:



Year	Percentage
2019	104.781	%
2020	103.188	%
2021	101.594	%
2022 and thereafter	100.000	%

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").

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, 2016, 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 financial 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"), the Match Group borrowed $800 million in the form of a term loan (the "Match Group Term Loan"). On March 31, 2016, the Company made a $10 million principal payment on the Match Group Term Loan. In addition, on June 1, 2016, the $400 million in proceeds from the 2016 Match Group Senior Notes were used to repay a portion of the Match Group Term Loan. The remaining principal balance at June 30, 2016 of $390 million is due at maturity. The Match Group Term Loan would require 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 our option, at a base rate or LIBOR, plus 3.50% or 4.50%, respectively, and in the case of LIBOR, a floor of 1.00%. 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, 2016 and December 31, 2015, 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 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.

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. The guarantor subsidiaries are the same for the 2013 and 2012 Senior Notes. See Note 14 for guarantor and non-guarantor financial information.

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, 2016, 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 million revolving credit facility (the "IAC Credit Facility") that expires October 7, 2020. At June 30, 2016 and December 31, 2015, 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 Senior Notes and 2012 Senior Notes rank equally with each other, and are subordinate to outstanding borrowings under the IAC Credit Facility.

________________________

^(a) The impact on earnings of Match Group's dilutive securities is not applicable for the three and six months ended June 30, 2015 as it was a wholly-owned subsidiary of the Company until its IPO on November 24, 2015.

^(b) For the three and six months ended June 30, 2016, the impact on earnings related to Match Group's dilutive securities under the if-converted method are excluded as the impact is anti-dilutive.

^(c) For the three and six months ended June 30, 2016, the Company had a loss from continuing operations and as a result, approximately 10.1 million potentially dilutive securities were excluded from computing dilutive earnings per share because the impact would have been anti-dilutive. Accordingly, the weighted average basic shares outstanding were used to compute all earnings per share amounts.

^(d)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, 2015, 1.0 million and 1.2 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive.

SEGMENT INFORMATION

Segment Reporting [Abstract]

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. 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.

^(b) Consistent with the Company's primary metric (described in (a) above), the Company excludes, if applicable, goodwill and intangible assets from the measure of segment assets presented above.

Revenue by geography is based on where the customer is located. Geographic information about revenue and long-lived assets is presented below:

SUPPLEMENTAL CASH FLOW INFORMATION	SUPPLEMENTAL CASH FLOW INFORMATION Supplemental Disclosure of Non-Cash Transactions: The Company recorded acquisition-related contingent consideration liabilities of $27.1 million during the six months ended June 30, 2015. See Note 6 for additional information on contingent consideration arrangements.

CONTINGENCIES	6 Months Ended
CONTINGENCIES	Jun. 30, 2016
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 for additional information related to income tax contingencies.

- Definition

The entire disclosure for loss and gain contingencies. Describes any existing condition, situation, or set of circumstances involving uncertainty as of the balance sheet date (or prior to issuance of the financial statements) as to a probable or reasonably possible loss incurred by an entity that will ultimately be resolved when one or more future events occur or fail to occur, and typically discloses the amount of loss recorded or a range of possible loss, or an assertion that no reasonable estimate can be made.

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 30, 2016
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, 2015.
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 those 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 substantial 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"). The Company's service agreement became effective on April 1, 2016, following the expiration of the previous services agreement. This services agreement expires on March 31, 2020; the Company may choose to terminate the agreement effective March 31, 2019. This services agreement requires that we comply with certain guidelines promulgated by Google. Google may generally unilaterally update its own 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 Pronouncement	Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2016-09, Improvements to Employee Share-Based Payments Accounting (Topic 718). The update is intended to simplify existing guidance on various aspects of the accounting and presentation of employee share-based payments in financial statements including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification on the statement of cash flows. The provisions of ASU 2016-09 are effective for reporting periods beginning after December 15, 2016; early adoption is permitted. The Company is currently evaluating the impact the adoption of this standard update will have on its consolidated financial statements. 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 2016-02 are effective for reporting periods beginning after December 15, 2018; early adoption is permitted. The provisions of ASU 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 April 2015, the FASB issued ASU No. 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, and in August 2015, the FASB issued ASU 2015-15, Interest-Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. Together, this guidance requires that deferred debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the associated debt liability, while debt issuance costs related to line-of-credit arrangements may still continue to be classified as assets. The Company adopted the provisions of ASU 2015-03 and ASU 2015-15 in the first quarter of 2016 and applied the provisions retrospectively, resulting in $21.3 million of deferred debt issuance costs being reclassified from other non-current assets to long-term debt, net of current portion, in the accompanying December 31, 2015 consolidated balance sheet. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which clarifies the principles for recognizing revenue and develops a common standard for all industries. In July 2015, the FASB decided to defer the effective date for annual reporting periods beginning after December 15, 2017. In March, April and May 2016, the FASB issued ASU 2016-08, ASU 2016-10 and ASU 2016-12, respectively, which provide further revenue recognition guidance related to principal versus agent considerations, performance obligations and licensing, and narrow-scope improvements and practical expedients. Early adoption is permitted beginning on the original effective date of December 15, 2016. Upon adoption, ASU 2014-09 may either be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. The Company is currently evaluating the impact the adoption of this standard update will have on its consolidated financial statements, and the method and timing of adoption.
