NOTE 1—THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

IAC is a leading media and Internet company comprised of widely known consumer brands such as Vimeo, Dotdash (formerly About.com), Dictionary.com, The Daily Beast and Investopedia, along with ANGI Homeservices Inc., which operates HomeAdvisor and Angie's List, 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 September 29, 2017, the Company completed its previously announced combination (the "Combination") of the businesses in the Company's HomeAdvisor segment and Angie's List, Inc. ("Angie's List") under a new publicly traded company called ANGI Homeservices Inc. ("ANGI Homeservices"). At September 30, 2017, IAC owned 87.1% and 98.5% of the economic and voting interest, respectively, of ANGI Homeservices. See "Note 3—Business Combination" for further information. In connection with the transaction, the Company changed the name of the HomeAdvisor segment to ANGI Homeservices and year-over-year comparisons for financial results for this segment are to the historical results of the HomeAdvisor segment (adjusted to reflect corporate allocations from IAC).

In connection with the Combination and in consideration for the transfer by USANi LLC, a wholly-owned subsidiary of the Company ("USANi"), to the Company of all common membership units of HomeAdvisor International, LLC held by USANi, on September 29, 2017, the Company issued a total of 67,633 shares of Series C Cumulative Preferred Stock (the “Series C Preferred Stock”) to USANi. The Company established the Series C Preferred Stock, par value $0.01 per share, on September 28, 2017. The Series C Preferred Stock is entitled to receive a cash dividend of $75.00 per share per annum, payable quarterly in arrears. The outstanding Series C Preferred Stock eliminates in the Company's consolidated financial statements.

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.

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.

In management's opinion, the unaudited interim consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and reflect all adjustments, consisting of normal and recurring adjustments, necessary for the fair presentation of our financial position, results of operations and cash flows for the periods presented. Interim results are not necessarily indicative of the results that may be expected for the full year. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the audited 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 recoverability of goodwill and indefinite-lived intangible assets; the useful lives and recoverability of definite-lived intangible assets and property and equipment; the fair value of long-term investments; 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 nine months endedSeptember 30, 2017, revenue from Google represents 21% and 23%, respectively, of the Company's consolidated revenue. For the three and nine months endedSeptember 30, 2016, revenue from Google represents 23% and 27%, respectively, of the Company's consolidated revenue.

The services agreement became effective on April 1, 2016, following the expiration of the previous services agreement, and expires on March 31, 2020; however, the Company may choose to terminate the agreement effective March 31, 2019. The services agreement requires that the Company 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 nine months endedSeptember 30, 2017, revenue earned from Google was $176.8 million and $539.2 million, respectively. For the three and nine months endedSeptember 30, 2016, revenue earned from Google was $172.0 million and $638.2 million, respectively. This revenue is earned by the businesses comprising the Applications and Publishing segments. For the three and nine months endedSeptember 30, 2017, revenue earned from Google represents 82% and 83% of Applications revenue and 72% and 71% of Publishing revenue. For the three and nine months endedSeptember 30, 2016, revenue earned from Google represents 85% and 87% of Applications revenue and 66% and 76% of Publishing revenue, respectively. Accounts receivable related to revenue earned from Google totaled $62.0 million and $65.8 million at September 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, 2016 and 2017; these amendments provide further revenue recognition guidance related to principal versus agent considerations, performance obligations and licensing, 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.

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 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 Company’s assessment of the accounting for mobile app store fees incurred by Match Group in connection with obtaining members is still preliminary and ongoing. Match Group currently capitalizes these costs and amortizes them over the period of the applicable membership periods, which generally range from one to six months. The Company’s initial conclusions in applying ASU No. 2014-09 to these costs were: (1) these costs represent the incremental direct costs of obtaining a membership contract and (2) would, therefore, continue to be capitalized and amortized as incurred. The Company is reassessing this conclusion in light of its finding that there are divergent and evolving interpretations of the correct application of ASU No. 2014-09 to these costs. The total capitalized mobile app store fees were $19.8 million as of September 30, 2017.

• Within ANGI Homeservices, the effect of the adoption of ASU No. 2014-09 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. Prior to the Combination, Angie's List capitalized sales commissions and amortized the cost over the term of the applicable advertising contract. Following the Combination, Angie's List accounting policies will be conformed to the Company's accounting policies and these costs will be expensed as incurred. Following the adoption of ASU No. 2014-09, these costs will be capitalized and amortized over the average life of a service professional.

• Within Applications, the primary effect of the adoption of ASU No. 2014-09 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.

The Company does not expect the adoption of ASU No. 2014-09 to have a material effect 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 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 will adopt ASU No. 2016-02 effective January 1, 2019. The Company is currently evaluating the impact the adoption of this standard update will have on its consolidated financial statements.

Accounting Pronouncements adopted by the Company

In 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 early adopted the provisions of ASU No. 2017-09 during the third quarter of 2017 and the adoption of this standard update did not have a material impact on its consolidated financial statements.

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 nine months ended September 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 nine months ended September 30, 2017 were $314.3 million. Excess tax benefits of $43.1 million for the nine months ended September 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 1.1 million and 2.0 million shares for the three and nine months endedSeptember 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.

NOTE 2—INCOME TAXES

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

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

our tax environment changes. To the extent that the expected annual effective income tax rate changes during a quarter, the effect of the change on prior quarters is included in income tax provision in the quarter in which the change occurs.

For the three and nine months endedSeptember 30, 2017, the Company recorded an income tax benefit of $279.5 million and $322.8 million, respectively. The income tax benefit for the three and nine months endedSeptember 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 exercise, purchase or settlement of stock-based awards of $314.3 million for the nine months ended September 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 nine months endedSeptember 30, 2016, the Company recorded an income tax provision of $17.8 million and an income tax benefit of $77.4 million, respectively, which represents effective income tax rates of 25% and 37%, respectively. The effective tax rate for the three months ended September 30, 2016 is lower than the statutory rate of 35% due primarily to foreign income taxed at lower rates. The effective tax rate for the nine months ended September 30, 2016 is higher than the statutory rate of 35% due primarily to foreign income taxed at lower rates, state taxes and the non-taxable gain on the sale of PriceRunner, partially offset by the non-deductible portion of the goodwill impairment at the Publishing segment.

The Company recognizes interest and, if applicable, penalties related to unrecognized tax benefits in the income tax provision. At September 30, 2017 and December 31, 2016, the Company has accrued $3.3 million and $2.6 million, respectively, for the payment of interest. At both September 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 2013 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 September 30, 2017 and December 31, 2016, unrecognized tax benefits, including interest and penalties, are $43.0 million and $41.0 million, respectively. If unrecognized tax benefits at September 30, 2017 are subsequently recognized, $39.4 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 $22.5 million by June 30, 2018, due to expirations of statutes of limitations; $22.0 million of which would reduce the income tax provision.

The Company regularly assesses the realizability of deferred tax assets considering all available evidence including, among other things, the nature, frequency and severity of prior cumulative losses, forecasts of future taxable income, the duration of statutory carryforward periods, available tax planning and historical experience, to the extent these items are applicable. As of September 30, 2017, the Company has a gross deferred tax asset of $221.5 million that the Company expects to fully utilize on a more likely than not basis.

NOTE 3—BUSINESS COMBINATION

On September 29, 2017, the Company completed its previously announced combination of the businesses in the Company's HomeAdvisor segment and Angie's List under a new publicly traded company called ANGI Homeservices. Through the Combination, ANGI Homeservices acquired 100% of the common stock of Angie's List on September 29, 2017 for a total purchase price valued at $781.4 million. Angie’s List is a nationwide marketplace for local services where consumers can research, hire, rate and review the providers of these services. Ratings and reviews assist members in identifying and hiring a provider for their local service needs. Angie’s List's services are provided in markets located across the continental United States.

The purchase price of $781.4 million was determined based on the sum of (i) the fair value of the 61.3 million shares of Angie's List common stock outstanding immediately prior to the Combination based on the closing stock price of Angie's List

12

common stock on the NASDAQ on September 29, 2017 of $12.46per share; (ii) the cash consideration of$1.9 millionpaid to holders of Angie's List common stock who elected to receive$8.50 in cash per share; and (iii) the fair value of vested equity awards (including the pro rata portion of unvested awards attributable to pre-combination services) outstanding under Angie's List stock plans on September 29, 2017. Each stock option to purchase shares of Angie's List common stock that was outstanding immediately prior to the effective time of the Combination was, as of the effective time of the Combination, converted into an option to purchase (i) that number of Class A shares of ANGI Homeservices equal to the total number of shares of Angie's List common stock subject to such Angie's List option immediately prior to the effective time of the Combination, (ii) at a per-share exercise price equal to the exercise price per share of Angie's List common stock at which such Angie's List option was exercisable immediately prior to the effective time of the Combination. Each award of Angie's List restricted stock units that was outstanding immediately prior to the effective time of the Combination was, as of the effective time of the Combination, converted into an ANGI Homeservices restricted stock unit award with respect to a number of Class A shares of ANGI Homeservices equal to the total number of shares of Angie's List common stock subject to such Angie's List restricted stock unit award immediately prior to the effective time of the Combination.

The table below summarizes the purchase price:

	Angie's List
	(In thousands)
Class A common stock	$	763,684
Cash consideration for holders who elected to receive $8.50 in cash per share of Angie's List common stock	1,913
Fair value of vested and pro rata portion of unvested stock options attributable to pre-combination services	11,749
Fair value of the pro rata portion of unvested restricted stock units attributable to pre-combination services	4,038
Total purchase price	$	781,384

The financial results of Angie's List are included in the Company's consolidated financial statements, within the ANGI Homeservices segment, beginning September 29, 2017. For the three and nine months endedSeptember 30, 2017, the Company included $0.7 million of revenue and $20.0 million of net losses in its consolidated statement of operations related to Angie's List. The Company is in the process of completing its determination of the fair values of assets acquired and liabilities assumed and the preliminary fair values are subject to revision. These fair values are expected to be finalized in the fourth quarter of 2017.

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

	Angie's List
	(In thousands)
Cash and cash equivalents	$	44,270
Other current assets	10,641
Property and equipment	16,341

The purchase price was based on the expected financial performance of Angie's List, not on the value of the net identifiable assets at the time of combination. This resulted in a significant portion of the purchase price being attributed to goodwill because Angie's List is complementary and synergistic to the other North America businesses of ANGI Homeservices.

The preliminary estimated fair values of the identifiable intangible assets acquired at the date of combination are as follows:

	Angie's List
	(In thousands)		Weighted-average useful life (years)
Indefinite-lived trade names and trademarks	$	137,000	Indefinite
Service providers	90,500		3
Developed technology	63,900		6
Memberships	15,900		3
User base	10,000		1
Total identifiable intangible assets acquired	$	317,300

Other current assets, current liabilities and other long-term liabilities of Angie's List were reviewed and adjusted to their fair values at the date of combination, as necessary. The fair value of deferred revenue was determined using an income approach that utilized a cost to fulfill analysis. The fair values of trade names and trademarks were determined using an income approach that utilized the relief from royalty methodology. The fair values of developed technology and user base were determined using a cost approach that utilized the cost to replace methodology. The fair values of the service providers and memberships were determined using an income approach that utilized the excess earnings methodology. The valuations of deferred revenue and intangible assets incorporate significant unobservable inputs and require significant judgment and estimates, including the amount and timing of future cash flows, cost and profit margins related to deferred revenue 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 Angie's List as if the Combination had occurred on January 1, 2016. The unaudited 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 the results that would have been achieved had the Combination actually occurred on January 1, 2016. For the three and nine months endedSeptember 30, 2017, pro forma adjustments include (i) reductions in stock-based compensation expense of $85.1 million and $52.8 million, respectively, and transaction related costs of $22.1 million and $25.6 million, respectively, because they are one-time in nature and will not have a continuing impact on operations; and (ii) an increase in amortization of intangibles of $11.4 million and $34.4 million, respectively. The stock-based compensation expense is related to the modification of previously issued HomeAdvisor vested equity awards, which were converted into ANGI Homeservices' equity awards, and the acceleration of previously issued Angie's List equity awards held by employees terminated in connection with the Combination. The transaction related costs include severance and retention costs of $12.0 million related to the Combination. For the three and nine months endedSeptember 30, 2016, pro forma adjustments include a reduction in revenue of $5.0 million and $31.4 million, respectively, due to the write-off of deferred revenue at the date of acquisition as well as increases in stock-based compensation expense of $19.7 million and $51.4 million, respectively, and amortization of intangibles of $14.0 million and $42.1 million, respectively.

The additions primarily relate to the acquisitions of MyHammer Holding AG (included in the ANGI Homeservices segment) and VHX (included in the Video segment). The deductions primarily relate to the sales of PriceRunner and ShoeBuy (both included in the Other segment). During the second quarter of 2016, the Company recorded impairment charges related to the entire $275.4 million balance of the Publishing reporting unit goodwill. The goodwill impairment charge at Publishing was driven by the impact from the new Google services agreement, traffic trends and monetization challenges and the corresponding impact on the current estimate of fair value.

The September 30, 2017 and December 31, 2016 goodwill balance reflects accumulated impairment losses of $598.0 million, $529.1 million and $11.6 million at Publishing, Applications and Connected Ventures (included in the Video segment), respectively.

NOTE 5—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 September 30, 2017, there is one contingent consideration arrangement related to a business acquisition. The maximum contingent payment related to this arrangement is $3.0 million and the gross fair value of this arrangement, before the unamortized discount, at September 30, 2017 is $2.1 million.

The sole remaining contingent consideration arrangement is based upon earnings performance. Previous contingent consideration arrangements were based upon earnings performance and/or operating metrics. The Company determined the fair value of the contingent consideration arrangement by using probability-weighted analyses to determine the amounts of the gross liability, and, because the arrangement was 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 fair values of the contingent consideration arrangements at both September 30, 2017 and December 31, 2016 reflect discount rates of 12%.

The fair value of contingent consideration arrangements is 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 September 30, 2017 and December 31, 2016 includes a current portion of $0.6 million and $33.4 million, respectively, and a non-current portion of $1.2 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 September 30, 2017 and December 31, 2016, the carrying values of the Company's investments accounted for under the cost method totaled $116.2 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:

^(a)  The Match Group Term Loan matures on November 16, 2022; provided that, if any of the Match Group 6.75% Senior Notes remain outstanding on the date that is 91 days prior to the maturity date of the Match Group 6.75% Senior Notes, the Match Group Term Loan maturity date shall be September 15, 2022, the date that is 91 days prior to the maturity date of the Match Group 6.75% Senior Notes.

Match Group Senior Notes

The Match Group 6.375% 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 Match Group 6.75% Senior Notes were issued on November 16, 2015, in exchange for a portion of the 4.75% Senior Notes (the "Match Exchange Offer"). At any time prior to December 15, 2017, the Match Group 6.75% 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 Match Group 6.375% and 6.75% 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 September 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 March 31, 2016, Match Group made a $10 million principal payment on the Match Group Term Loan. On June 1, 2016, the $400 million in proceeds from the Match Group 6.375% Senior Notes, described above, were used to repay 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 was due at maturity, was repriced. On August 14, 2017, the Match Group Term Loan was increased by $75 million. In addition, the outstanding balance of $425 million was repriced at LIBOR plus 2.50%, and the LIBOR floor was reduced to 0.00%. 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 interest rate on the Match Group Term Loan at September 30, 2017 is 3.81%. Interest payments are due at least quarterly 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 September 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 Match Group 6.75% and 6.375% Senior Notes to the extent of the value of the assets securing the borrowings under the Match Group Credit Agreement.

IAC Senior Notes

The 4.875% and 4.75% Senior Notes were issued by IAC on November 15, 2013 and December 21, 2012, respectively. The 4.875% and 4.75% Senior Notes are unconditionally guaranteed by certain wholly-owned domestic subsidiaries, which are designated as guarantor subsidiaries; neither Match Group, ANGI Homeservices nor any of their subsidiaries guarantee any debt of IAC, or in the case of Match Group and its subsidiaries are subject to any of the covenants related to such debt. The guarantor subsidiaries are the same for the 4.875% and 4.75% Senior Notes. See "Note 13—Guarantor and Non-guarantor Financial Information" for financial information relating to guarantor and non-guarantor subsidiaries.

For the nine months endedSeptember 30, 2017, the Company redeemed and repurchased $28.3 million of its 4.875% Senior Notes and repurchased $3.3 million of its 4.75% Senior Notes. For the nine months endedSeptember 30, 2016, the Company redeemed and repurchased $109.8 million of its 4.875% Senior Notes and repurchased $16.5 million of its 4.75% Senior Notes.

On October 2, 2017, a subsidiary of the Company issued $517.5 million aggregate principal amount of 0.875% Exchangeable Senior Notes due October 1, 2022, which are guaranteed by the Company. The proceeds from these notes were, in part, loaned to IAC, which repaid the outstanding balance of the 4.875% Senior Notes of $361.9 million. See "Note 14—Subsequent Events" for further information.

IAC Credit Facility

IAC has a $300.0 million revolving credit facility (the "IAC Credit Facility") that expires October 7, 2020. At September 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 4.875% and 4.75% Senior Notes and are also secured by the stock of certain of our domestic and foreign subsidiaries. The 4.875% and 4.75% Senior Notes rank equally with each other, and are subordinate to outstanding borrowings under the IAC Credit Facility to extent of the value of the assets securing such borrowings.

________________________

^(a)  The amount for the three and nine months endedSeptember 30, 2017 and for the three months endedSeptember 30, 2016 reflects the reduction in Match Group's earnings attributable to IAC from the assumed exercise of Match Group dilutive securities under the if-converted method. For the nine months endedSeptember 30, 2016, the impact on earnings related to 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)  Dilutive securities for the three and nine months endedSeptember 30, 2017, includes the impact from the assumed exercise of ANGI Homeservices dilutive securities under the if-converted method, as it is more dilutive for IAC to settle certain ANGI Homeservices equity awards. The impact on earnings of ANGI Homeservices dilutive securities is not applicable for priors prior to the Combination.

^(c)  If the effect is dilutive, weighted average common shares outstanding include the incremental shares that would be issued upon the assumed exercise of stock options and subsidiary denominated equity and vesting of restricted stock units ("RSUs"). For the three months endedSeptember 30, 2017, there were no potentially dilutive securities excluded from the calculation of diluted earnings per share. For the nine months endedSeptember 30, 2017 and three months endedSeptember 30, 2016, less than 0.1 million and 3.3 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive.

^(d)  For the nine months endedSeptember 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. Accordingly, the weighted average basic shares outstanding were used to compute the diluted earnings per share amount.

^(e)  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 the three and nine months endedSeptember 30, 2017 and three months endedSeptember 30, 2016, 0.3 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.

NOTE 9—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 reportable segments.

________________________

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

NOTE 11—CONTINGENCIES

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

NOTE 14—SUBSEQUENT EVENTS

On October 2, 2017, IAC FinanceCo, Inc., a direct, wholly-owned subsidiary of the Company, completed a private offering of $517.5 million aggregate principal amount of its 0.875% Exchangeable Senior Notes due October 1, 2022 (the “0.875% Exchangeable Senior Notes”), with interest payable each April 1 and October 1, commencing on April 1, 2018. The 0.875% Exchangeable Senior Notes are guaranteed by the Company.

The net proceeds from the sale of the 0.875% Exchangeable Senior Notes were approximately $500.5 million, after deducting fees and expenses. The net proceeds from the offering were used to:

• pay the net premium of approximately $50.7 million on the exchangeable note hedge and warrant transactions; and

• loaned to IAC, which repaid the outstanding balance of the 4.875% Senior Notes of $361.9 million, plus accrued interest of $8.8 million. The 4.875% Senior Notes were called for redemption on October 2, 2017 and will be redeemed and canceled on November 30, 2017. In connection with the call for redemption, the Company satisfied and discharged that certain Indenture, dated as of November 15, 2013, by and among the Company, as issuer, the guarantors named therein and Computershare Trust Company, N.A., as trustee, relating to the 4.875% Senior Notes.

The exchange rate for the 0.875% Exchangeable Senior Notes is initially 6.5713 shares of the Company's common stock per $1,000 principal amount of the notes, which is equivalent to an initial exchange price of $152.18 per share of the Company's common stock. In connection with this debt offering, the Company purchased call options at $152.18 per share, covering the entire 3.4 million shares that would be issuable upon the conversion of the notes, and sold warrants for 3.4 million shares at $229.70 per share. The exchangeable note hedge transactions are expected to reduce the potential dilutive effect of the Company's common stock upon any exchange of notes and/or offset any cash payment IAC FinanceCo, Inc. is required to make in excess of the principal amount of the exchanged notes. The warrants could separately have a dilutive effect on the Company's common stock to the extent that the market price per share of the Company common stock (as measured over the measurement period at the maturity of the warrants) exceeds the applicable strike price of the warrants.

On October 2, 2017, IAC Group, LLC, a wholly-owned subsidiary of the Company, entered into a joinder agreement by and among IAC Group, the Company, and each of the other loan parties party to the IAC Credit Facility. Pursuant to the joinder agreement, IAC Group became the successor borrower under the IAC Credit Facility and IAC's obligations under the credit agreement were terminated.

On October 23, 2017, the Company, through Match Group, sold its largest cost method investment, Zhenai Inc., a leading provider of online dating and matchmaking services in China. The net proceeds from the sale were $60.2 million.

On November 1, 2017, ANGI Homeservices entered into a credit agreement which provides for a five-year term loan A facility of $275 million ("ANGI Homeservices Term Loan"). The ANGI Homeservices Term Loan is guaranteed by ANGI Homeservices' wholly-owned material domestic subsidiaries and is secured by substantially all assets of ANGI Homeservices and the guarantors, subject to certain exceptions. The ANGI Homeservices Term Loan currently bears interest at LIBOR plus 200 basis points, which is subject to change based on the borrower's consolidated net leverage ratio. Interest payments are due at least quarterly through the term of the loan. The ANGI Homeservices Term Loan also requires quarterly amortization payments of 1.25% of the original principal amount thereof in the first three years, 2.5% in the fourth year and 3.75% thereafter. A portion of the proceeds of the loan were used to repay the Intercompany Notes and the remaining proceeds will be used for general corporate purposes. See "Note 12—Related Party Transactions with ANGI Homeservices" for further information on the Intercompany Notes outstanding between ANGI Homeservices and the Company.

Cost of revenue also includes production costs related to media produced by Electus and other businesses within our Video segment, customer service functions within the Match Group segment, expenses associated with the operation of the Company's data centers, consisting of compensation (including stock-based compensation expense) and other employee-related costs, hosting fees, credit card processing fees, content acquisition costs and rent. Cost of revenue in 2016 includes ShoeBuy's cost of products sold, including shipping and handling costs, and The Princeton Review's cost for teachers and tutors.

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

• General and administrative expense - consists primarily of compensation (including stock-based compensation expense) and other employee-related costs for personnel engaged in executive management, finance, legal, tax, human resources and customer service functions (except for Match Group which includes customer service costs within cost of revenue), fees for professional services, facilities costs, bad debt expense and acquisition-related contingent consideration fair value adjustments (described below).

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

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

Management Overview

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

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

A meaningful portion of the revenue from our Applications and Publishing segments is derived from online advertising, most of which is attributable to our services agreement with Google Inc. ("Google"). The Company's services agreement became effective on April 1, 2016, following the expiration of the previous services agreement. The services agreement expires on March 31, 2020; however, the Company may choose to terminate the agreement effective March 31, 2019. The services agreement requires that we comply with certain guidelines promulgated by Google, and Google may generally unilaterally update its policies and guidelines without advance notice. Any such updates could in turn require modifications to, or prohibit and/or render obsolete certain of our products, services and/or business practices, which could be costly to address or otherwise have an adverse effect on our business, financial condition and results of operations. For the three and nine months endedSeptember 30, 2017, revenue earned from Google was $176.8 million and $539.2 million, respectively. For the three and nine months ended September 30, 2016, revenue earned from Google was $172.0 million and $638.2 million, respectively. Given the new services agreement with Google has been in place for a full year as of April 1, 2017, the Company experienced year-over-year consolidated growth in revenue earned from Google for the three months endedSeptember 30, 2017. The decline in Google revenue in the first nine months of 2017 compared to the first nine months of 2016 was due primarily to the effects of the new contract. For the three and nine months endedSeptember 30, 2017, revenue from Google represents 21% and 23%, respectively, of the Company's consolidated revenue. For the three and nine months endedSeptember 30, 2016, revenue from Google represents 23% and 27%, respectively, of the Company's consolidated revenue. For the three and nine months endedSeptember 30, 2017, revenue earned from Google represents 82% and 83% of Applications revenue and 72% and 71% of Publishing revenue. For the three and nine months endedSeptember 30, 2016, revenue earned from Google represents 85% and 87% of Applications revenue and 66% and 76% of Publishing revenue, respectively.

On October 18, 2017, Vimeo acquired Livestream, a leading live video solution that powers millions of events a year.

On October 2, 2017, a finance subsidiary of the Company issued $517.5 million aggregate principal amount of 0.875% Exchangeable Senior Notes due October 1, 2022, which notes are guaranteed by the Company. The proceeds from these notes were, in part, loaned to IAC, which repaid the outstanding balance of its 4.875% Senior Notes of $361.9 million. See "Note 14—Subsequent Events" to the consolidated financial statements included in "Item 1. Consolidated Financial Statements" for further information.

On September 29, 2017, the Company completed its previously announced combination of the businesses in the Company's HomeAdvisor segment and Angie's List, Inc. ("Angie's List") under a new publicly traded company called ANGI Homeservices (the "Combination"). At September 30, 2017, IAC owned 87.1% and 98.5% of the economic and voting interest, respectively, of ANGI Homeservices. See "Note 3—Business Combination" to the consolidated financial statements included in "Item 1. Consolidated Financial Statements" for additional information related to the Combination. In connection with the Combination, the Company changed the name of its HomeAdvisor segment to ANGI Homeservices and year-over-year comparisons for financial results for this segment are to the historical results of the HomeAdvisor segment (adjusted to reflect corporate allocations from IAC). During the three and nine months ended September 30, 2017, the Company incurred $26.0 million and $29.7 million, respectively, in costs related to this transaction (including severance, retention, transaction and integration related costs). The Company expects the aggregate amount of transaction-related expenses during 2017 and 2018 (including those previously recognized) to be less than $75 million. The Company also incurred $96.9 million in stock-based compensation expense during the third quarter of 2017 related to the modification of previously issued HomeAdvisor vested equity awards, which were converted into ANGI Homeservices' equity awards, and the acceleration of previously issued Angie's List equity awards held by employees terminated in connection with the Combination. On November 1, 2017, ANGI Homeservices entered into a credit agreement which provides for a five-year term loan A facility of $275 million. See "Note 14—Subsequent Events" to the consolidated financial statements included in "Item 1. Consolidated Financial Statements" for further information.

On August 14, 2017, the Match Group Term Loan was increased by $75 million. In addition, the outstanding balance of $425 million was repriced at LIBOR plus 2.50%, and the LIBOR floor was reduced to 0.00%. Previously, the interest charged on the Match Group Term Loan was LIBOR plus 3.25%, with a LIBOR floor of 0.75%.

In July 2017, Match Group elected to convert all outstanding equity awards of its wholly-owned subsidiary Tinder, which awards were primarily held by current and former Tinder employees, to stock options of Match Group (the "Tinder Equity Plan Settlement"). Subsequently, during the third quarter of 2017, Match Group made cash payments of approximately $500 million to cover both withholding taxes paid on behalf of exercising employees whose awards were net settled and the purchase of certain fully vested awards.

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.

HomeAdvisor acquired controlling interests in MyBuilder Limited ("MyBuilder") on March 24, 2017, and HomeStars Inc. ("HomeStars") on February 8, 2017, leading home services platforms in the United Kingdom and Canada, respectively.

Third Quarter and Year to Date September 2017 Consolidated Results

45

For the three months ended September 30, 2017, the Company's revenue increased $64.3 million, or 8%. Despite the revenue increase, operating income decreased to a loss of $18.6 million from income of $85.6 million in the prior year and Adjusted EBITDA decreased $1.4 million, or 1%. Revenue increased due primarily to strong growth of $55.9 million from Match Group, $48.2 million from ANGI Homeservices and $18.4 million from Video, partially offset by a decline of $65.5 million from Other due to the sales of ShoeBuy and The Princeton Review on December 30, 2016 and March 31, 2017, respectively. The operating loss was due primarily to an increase of $110.8 million in stock-based compensation expense and the decrease of $1.4 million in Adjusted EBITDA described below, partially offset by a decrease of $9.9 million in amortization of intangibles. The decrease in Adjusted EBITDA is primarily driven by decreases of $17.6 million from ANGI Homeservices due primarily to costs of $26.0 million (including severance, retention, transaction and integration related costs) related to the Combination, $3.5 million from Applications and increased losses of $3.4 million from Corporate, partially offset by a profit from Publishing of $7.1 million in 2017 compared to a loss of $6.2 million in 2016 and growth of $12.5 million from Match Group.

For the nine months ended September 30, 2017, the Company's revenue increased $27.9 million, or 1%, operating income increased $239.6 million from a loss of $145.4 million in the prior year and Adjusted EBITDA grew $47.1 million, or 14%. Revenue increased due primarily to strong growth of $138.0 million from ANGI Homeservices, $128.5 million from Match Group and $21.7 million from Video, partially offset by a decline of $172.3 million from Other due to the sales of ShoeBuy, The Princeton Review and PriceRunner on December 30, 2016, March 31, 2017 and March 18, 2016, respectively, and a significant decline of $81.2 million from Publishing primarily due to the effects of the new Google contract. The operating income increase was due primarily to the inclusion in 2016 of a $275.4 million goodwill impairment charge at Publishing, an increase of $47.1 million in Adjusted EBITDA described below and a decrease of $42.9 million in amortization of intangibles, partially offset by an increase of $124.8 million in stock-based compensation expense. The goodwill impairment charge at Publishing in 2016 was driven by the impact from the Google contract, traffic trends and monetization challenges. The Adjusted EBTIDA increase was due primarily to growth of $39.9 million from Match Group, a profit from Publishing of $11.0 million in 2017 compared to a loss of $6.6 million in 2016 and growth of $11.8 million from Applications, partially offset by increased losses of $12.3 million from ANGI Homeservices due primarily to costs of $29.7 million (including severance, retention, transaction and integration related costs) related to the Combination, and $8.9 million from Corporate.

46

Match Group revenue increased 19% driven by International Direct Revenue growth of $39.9 million, or 39%, and North America Direct Revenue growth of $16.4 million, or 10%.

Publishing revenue increased 18% due to $9.6 million, or 20%, higher Ask & Other revenue and $4.3 million, or 16%, higher Premium Brands revenue. Ask & Other revenue increased due to higher paid traffic as the business has now fully anniversaried the renewal of the Google contract, which became effective April 1, 2016.

The increase in stock-based compensation expense was due to the modification of previously issued HomeAdvisor vested equity awards, which were converted into ANGI Homeservices' equity awards, and the acceleration of previously issued Angie's List equity awards held by employees terminated in connection with the Combination. General and administrative expense also includes transaction related costs of $9.5 million and integration related costs of $3.9 million in the current year period related to the Angie's List transaction, an increase of $2.3 million in bad debt expense due, in part, to higher revenue at the HomeAdvisor domestic business and $2.8 million from acquisitions that were made prior to the Combination.

• The Corporate increase was due primarily to higher compensation costs in 2017, including an increase in stock-based compensation expense due primarily to the issuance of new equity awards since 2016 and higher consulting fees.

• The Match Group increase was due primarily to an increase of $12.0 million in compensation, a change of $5.2 million in acquisition-related contingent consideration fair value adjustments (expense of $0.1 million in 2017 versus income of $5.1 million in 2016) and an increase of $2.5 million in professional fees. The increase in compensation was due primarily to the employer portion of payroll taxes paid for the exercise of Match Group options, increased headcount and an increase of $5.2 million in stock-based compensation expense due primarily to an increase in expense related to a subsidiary denominated equity award held by a non-employee, which award was settled during the third quarter of 2017. The increase in the acquisition-related contingent consideration fair value adjustments was due primarily to the final measurement and settlement of one arrangement in the current year period.

• The Other decrease was due primarily to the sales of The Princeton Review in March 2017 and ShoeBuy in December 2016.

As a percentage of revenue	22%			17%

General and administrative expense in 2017 increased from 2016 due to increases of $139.0 million from ANGI Homeservices, $33.3 million from Match Group and $11.7 million from Corporate, partially offset by decreases of $42.2 million from Other, $10.3 million from Applications and $9.6 million from Publishing.

• The ANGI Homeservices increase was due primarily to an increase of $95.6 million in compensation, $17.6 million in costs related to the Angie's List transaction including transaction related costs of $13.1 million and integration related costs of $4.0 million, $7.8 million from acquisitions that were made prior to the Combination and an increase of $7.8 million in bad debt expense. These increases are due primarily to the factors described above in the three-month discussion. General and administrative expense also increased as a result of an increase of $3.3 million in outsourced customer service expense.

• The Corporate increase was due primarily to the factors described above in three-month discussion.

• The Match Group increase was due primarily to an increase of $18.7 million in compensation, an increase in expense of $7.1 million in acquisition-related contingent consideration fair value adjustments (expense of $4.4 million in 2017 versus income of $2.7 million in 2016) and an increase of $5.2 million in professional fees. The increase in compensation was due to an increase of $9.5 million in stock-based compensation expense primarily to the factors described above in the three-month discussion as well as an increase in expense related to new grants issued since the prior year, the employer portion of payroll taxes paid for the exercise of Match Group options and an increase in headcount from business growth. The increase in professional fees was due primarily to the Tinder Equity Plan Settlement (See "Financial Position, Liquidity and Capital Resources" for additional information on this settlement).

• The Other decrease was due to the factors described above in the three-month discussion.

• The Applications decrease was due primarily to the inclusion in 2016 of $11.0 million in expense related to an acquisition-related contingent consideration fair value adjustment and a $2.9 million favorable legal settlement in 2017.

• The Publishing decrease was due primarily to reductions in workforce in 2016 including $2.5 million in restructuring costs included in 2016 as well as, the sale of ASKfm on June 30, 2016 and a decrease of $1.7 million in professional fees at Ask.com.

For the three months ended September 30, 2017 compared to the three months ended September 30, 2016

Operating income decreased to a loss in 2017 from income in 2016 due primarily to an increase of $110.8 million in stock-based compensation expense, a change of $2.5 million in acquisition-related contingent consideration fair value adjustments and a decrease of $1.4 million in Adjusted EBITDA described below, partially offset by a decrease of $9.9 million in amortization of intangibles. The increase in stock-based compensation expense was due primarily to modification and acceleration charges of $96.9 million related to the Angie's List transaction described above, an increase in expense related to a subsidiary denominated equity award held by a non-employee, which award was settled during the third quarter of 2017, and the issuance of new equity awards since 2016. The decrease in amortization of intangibles was due primarily to lower expense in 2017 related to a Publishing trade name and certain intangible assets from the PlentyOfFish acquisition that are now fully amortized, partially offset by expense in 2017 related to ANGI Homeservices acquisitions.

For the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016

Operating income in 2017 increased from a loss in 2016 due primarily to the inclusion in 2016 of a $275.4 million goodwill impairment charge at Publishing, an increase of $47.1 million in Adjusted EBITDA described below, a decrease of $42.9 million in amortization of intangibles and a change of $3.0 million in acquisition-related contingent consideration fair value adjustments, partially offset by increases of $124.8 million in stock-based compensation expense and $4.2 million in depreciation expense. The goodwill impairment charge at Publishing in 2016 was driven by the impact from the Google contract, traffic trends and monetization challenges. The decrease in amortization of intangibles and increase in stock-based compensation expense are due primarily to the factors described above in the three-month discussion. Amortization of intangibles was further impacted by the inclusion of an impairment charge in 2016 of $11.6 million related to certain Publishing indefinite-lived trade names.

At September 30, 2017, there was $449.1 million of unrecognized compensation cost, net of estimated forfeitures, related to all equity-based awards, which is expected to be recognized over a weighted average period of approximately 2.6 years.

For the three months ended September 30, 2017 compared to the three months ended September 30, 2016

Match Group Adjusted EBITDA increased 12% due primarily to an increase of $55.9 million in revenue and lower selling and marketing expense as a percentage of revenue as the product mix continues to shift towards brands with lower marketing spend, partially offset by an increase in cost of revenue, general and administrative expense and product development expense. General and administrative expense and product development expense increased due, in part, to expense of $11.3 million associated with the employer portion of payroll taxes and professional fees related to the Tinder Equity Plan Settlement.

ANGI Homeservices Adjusted EBITDA declined to a loss of $2.3 million in 2017, despite an increase of $48.2 million in revenue, due primarily to the inclusion in 2017 of $26.0 million in costs related to the Combination (including severance, retention, transaction and integration related costs), as well as an increase in selling and marketing expense at both the HomeAdvisor domestic and European businesses, and higher losses at the European businesses driven primarily by our European expansion strategy, including the higher selling and marketing expense described above and higher compensation costs.

Video Adjusted EBITDA loss improved 8% due primarily to the contribution from IAC Films, partially offset by lower profits at Electus and higher losses at Vimeo, which includes $0.9 million in transaction costs related to the acquisition of Livestream.

Applications Adjusted EBITDA decreased 10% due primarily to lower Partnerships revenue and higher marketing expense at Apalon.

Publishing Adjusted EBITDA improved to a profit of $7.1 million in 2017 from a loss of $6.2 million in 2016 due to higher revenue and lower operating costs resulting from restructurings in 2016, including $1.1 million in restructuring costs in the third quarter of 2016.

Corporate Adjusted EBITDA loss increased $3.4 million due primarily to higher compensation costs and consulting fees.

For the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016

Match Group Adjusted EBITDA increased 14% due primarily to an increase of $128.5 million in revenue and the factors described above in the three-month discussion.

ANGI Homeservices Adjusted EBITDA decreased 36%, despite an increase of $138.0 million in revenue, due primarily to the inclusion in 2017 of $29.7 million in costs related to the Combination and the other factors described above in the three-month discussion.

Video Adjusted EBITDA loss increased 3% due to lower revenue at Electus, partially offset by the contribution from IAC Films and reduced losses at Daily Burn.

Applications Adjusted EBITDA increased 13%, despite a 1% decrease in revenue, due primarily to decreases in cost of revenue and general and administrative expense. Adjusted EBITDA was impacted in 2016 by $2.5 million in restructuring costs.

Publishing Adjusted EBITDA improved to a profit of $11.0 million in 2017 from a loss of $6.6 million in 2016, despite lower revenue, due primarily to lower operating costs resulting from restructurings in 2016, including $7.0 million in restructuring costs in 2016.

Corporate Adjusted EBITDA loss increased $8.9 million due primarily to the factors described above in the three-month discussion.

Income tax benefit (provision)

	(Dollars in thousands)
Income tax benefit (provision)	$279,480	NM	NM	$(17,826)
Effective income tax rate	NM			25%

The 2017 income tax benefit was due primarily to the effect of adopting the provisions of the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, on January 1, 2017. Under ASU No. 2016-09, excess tax benefits generated by the exercise, purchase or settlement of stock-based awards of $257.0 million in the third quarter of 2017 are recognized as a reduction to the income tax provision rather than additional paid-in capital.

The 2016 effective income tax rate is lower than the statutory rate of 35% due primarily to foreign income taxed at lower rates.

We expect the fourth quarter and full year income tax provision to be impacted by employees exercising stock options, which will create an income tax benefit due to the application of ASU No. 2016-09 as discussed above, which could be significant depending on the volume of exercise activity.

The 2017 income tax benefit was due primarily to the factor described above in the three-month discussion. Excess tax benefits generated by the exercise, purchase or settlement of stock-based awards were $314.3 million for the first nine months of 2017.

The 2016 effective income tax rate is higher than the statutory rate of 35% on pre-tax losses due primarily to foreign income taxed at lower rates, state taxes and the non-taxable gain on the sale of PriceRunner, partially offset by the nondeductible portion of the goodwill impairment charge at the Publishing segment.

IAC'S PRINCIPLES OF FINANCIAL REPORTING

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

Definition of IAC's Non-GAAP Measure

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

For a reconciliation of operating income (loss) by reportable segment and net earnings attributable to IAC shareholders to Adjusted EBITDA for the three and nine months ended September 30, 2017 and 2016, see "Note 9—Segment Information" to the consolidated financial statements included in "Item 1. Consolidated Financial Statements."

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

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

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

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

58

Gains and losses recognized on changes in the fair value of contingent consideration arrangements are accounting adjustments to report contingent consideration liabilities at fair value. These adjustments can be highly variable and are excluded from our assessment of performance because they are considered non-operational in nature and, therefore, are not indicative of current or future performance or the ongoing cost of doing business.

Cash Flow Information

In summary, the Company's cash flows are as follows:

	(In thousands)

Net cash provided by (used in) investing activities	81,243			(106,412		)
Net cash used in financing activities	(462,055		)	(380,731		)

Net cash provided by operating activities consists of earnings, adjusted for stock-based compensation expense, depreciation, amortization of intangibles, goodwill impairment, deferred income taxes, acquisition-related contingent consideration fair value adjustments, adjustments related to gains on the sale of businesses and investments, impairments of long-term investments, an acquisition-related contingent consideration payment, and the effect of changes in working capital. Adjustments to earnings primarily consist of $344.1 million of deferred income taxes, $207.4 million of stock-based compensation expense, $55.5 million of depreciation, $24.0 million of net gains on sale of businesses and investments, $22.2 million of amortization of intangibles, $11.1 million of an acquisition-related contingent consideration payment, $20.9 million of bad debt expense, and $23.0 million of other adjustments, which primarily consists of net foreign currency exchange losses. The deferred tax benefit primarily relates to the net operating loss created by the excess tax benefit of $314.3 million related to the settlement of stock-based awards and the deferred tax benefit on the modification charge for the conversion and acceleration of stock-based awards. The increase from changes in working capital consist primarily of an increase in accounts payable and other current liabilities of $47.5 million and an increase in deferred revenue of $44.8 million, partially offset by an increase in accounts receivable of $78.6 million and an increase in other assets of $17.5 million. The increase in accounts payable and other current liabilities is due to: (i) an increase in accrued interest relating to the Company's Senior Notes and Match Group Senior Notes due to timing of interest payments, (ii) an increase in payables at Match Group due to timing of payments and at ANGI Homeservices due to increased advertising expenses, and (iii) an increase in accrued severance and retention and accrued professional fees at ANGI Homeservices related to the Combination. The increase in deferred revenue is due mainly to growth in membership revenue at Match Group, ANGI Homeservices and Vimeo, partially offset by decreases at Electus and Notional mainly due to the delivery of programming related to various production deals. The increase in accounts receivable is primarily due to (i) the timing of receipts and revenue increasingly sourced through mobile app stores at Match Group, and (ii) revenue growth at ANGI Homeservices. The increase in other assets is primarily related to an increase in prepaid marketing at ANGI Homeservices.

Net cash provided by investing activities includes net proceeds from sale of businesses and investments of $125.2 million, which is primarily related to the sale of The Princeton Review, and proceeds (net of purchases) of marketable debt securities of $89.4 million, partially offset by $69.1 million of cash used for the MyBuilder, Angie's List, and HomeStars acquisitions, and capital expenditures of $56.5 million, primarily related to the Company's purchase of a 50% ownership interest in an aircraft and investments in internal development of software at Match Group and ANGI Homeservices to support their products and services and computer hardware.

Net cash used in financing activities includes $501.4 million for the payment of (i) withholding taxes on behalf of Match Group employees for stock-based awards that were net settled and (ii) the purchase of certain fully vested awards (refer to "Liquidity and Capital Resources" below for further information), $57.2 million for the payment of withholding taxes on behalf of IAC employees for stock-based awards that were net settled, $56.4 million for the repurchase of 0.8 million shares of

61

common stock at an average price of $69.24 per share, $31.6 million for the redemption and repurchase of a portion of the 4.75% and 4.875% Senior Notes, $27.3 million in acquisition-related contingent consideration payments, and $13.0 million for the purchase of noncontrolling interests, partially offset by $75.0 million in proceeds from additional borrowings under the Match Group Term Loan, $69.1 million in proceeds related to the issuance of IAC common stock pursuant to stock-based awards, $57.7 million in proceeds related to the issuance of Match Group common stock pursuant to stock-based awards, a $20.1 million decrease in restricted cash that relates to settled IAC bond redemptions, and $10.6 million of funds returned from escrow for the MyHammer tender offer.

2016

Adjustments to earnings primarily consist of $275.4 million of goodwill impairment at the Publishing segment, $100.0 million of deferred income taxes, $82.6 million of stock-based compensation expense, $65.1 million of amortization of intangibles, $51.3 million of depreciation, $13.4 million of net gains on the sale of businesses and investments, $12.5 million of bad debt expense, $8.0 million of acquisition-related contingent consideration fair value adjustments, and $5.6 million in other adjustments that consist primarily of a non-cash charge on the repayment of $400 million of the Match Group Term Loan. The decrease from changes in working capital consist primarily of a decrease in accounts payable and other current liabilities of $63.7 million, a decrease in income taxes payable and receivable of $37.1 million, and an increase in other assets of $19.8 million, partially offset by a decrease in accounts receivable of $33.0 million and an increase in deferred revenue of $31.4 million. The decrease in accounts payable and other current liabilities is due to(i) a decrease in accrued advertising and revenue share expense at Publishing and Applications mainly due to the effect of the new Google contract, which became effective April 1, 2016,(ii) decreases in payables at Match Group and Applications due to the timing of payments and a seasonal decrease in payables to suppliers at ShoeBuy, (iii)a decrease in VAT payables related mainly to decreases in international revenue at Publishing, and (iv) a decrease in accrued employee compensation and benefits mainly related to the payment of 2015 cash bonuses in 2016.The decrease in income taxes payable and receivable is primarily due to the payment of 2015 tax liabilities in 2016. The excess tax benefit from stock-based awards was $43.1 million. The increase in other assets is primarily related to an increase in productions costs at IAC Films and an increase in prepaid maintenance contracts at Match Group. The decrease in accounts receivable is mainly due to a decrease at Publishing due to lower revenue related to the new services agreement with Google, partially offset by an increase atANGI Homeservicesdue to revenue growth. The increase in deferred revenue ismainly due to growth in prepaid revenue at Match Group, ANGI Homeservices, SlimWare and Vimeo.

Net cash used in investing activities includes purchases (net of sales and maturities) of marketable debt securities of $150.0 million, capital expenditures of $62.7 million, primarily related to Match Group and ANGI Homeservices investments in internal development of software to support their products and services, as well as leasehold improvements and computer hardware, and cash used in investments and acquisitions of $9.7 million, partially offset by net proceeds from the sale of businesses and investments of $110.5 million, which mainly consists of proceeds from the sale of PriceRunner.

Additionally, payments of $410.0 million were made toward the Match Group Term Loan, of which $400.0 million was financed by the issuance of the Match Group 6.375% Senior Notes.

Liquidity and Capital Resources

The Company's principal sources of liquidity are its cash and cash equivalents as well as cash flows generated from operations. IAC has a $300 million revolving credit facility that expires on October 7, 2020. Match Group has a $500 million revolving credit facility that expires on October 7, 2020. At September 30, 2017, there were no outstanding borrowings under the IAC Credit Facility or the Match Group Credit Facility.

On October 2, 2017, IAC FinanceCo, Inc. completed a private offering of $517.5 million aggregate principal amount of its 0.875% Exchangeable Senior Notes due 2022, which notes are guaranteed by the Company. Interest is payable each April 1 and October 1 and commences on April 1, 2018. In connection with the Notes offering, IAC FinanceCo, Inc. purchased a bond hedge and IAC sold warrants, in each case covering the same aggregate number of shares that would be issuable upon exchange of the Notes. The net proceeds from the sale of the 0.875% Exchangeable Senior Notes were approximately $500.5 million,

62

after deducting fees and expenses. The net proceeds from the offering were (i) used to pay the premium on the exchangeable note hedge transactions (calculated after taking into account the proceeds from the sale of the warrants) of approximately $50.7 million, and (ii) loaned to IAC, which repaid all of the Company's outstanding 4.875% Senior Notes of $361.9 million, plus accrued interest of $8.8 million. The 4.875% Senior Notes will be redeemed and canceled on November 30, 2017.

On September 29, 2017, the Company issued two intercompany notes (collectively referred to as "Intercompany Notes") to ANGI Homeservices as follows: (i) a Payoff Intercompany Note, which provided the funds necessary to repay the outstanding balance under Angie's List's existing credit agreement, totaling approximately $61.5 million; and (ii) a Working Capital Intercompany Note, which provided ANGI Homeservices with $15 million for working capital purposes.These amounts eliminate in the Company's consolidated balance sheet. On November 1, 2017, ANGI Homeservices entered into a credit agreement which provides for a five-year term loan A facility of $275 million (the "ANGI Homeservices Term Loan"). The ANGI Homeservices Term Loan is guaranteed by ANGI Homeservices' wholly-owned material domestic subsidiaries and is secured by substantially all assets of ANGI Homeservices and the guarantors, subject to certain exceptions. A portion of the proceeds of the loan were used to repay the aforementioned Intercompany Notes and the remaining proceeds will be used for general corporate purposes.

At September 30, 2017, IAC had 8.6 million shares remaining in its share repurchase authorization. IAC may purchase shares over an indefinite period of time on the open market and in privately negotiated transactions, depending on those factors IAC management deems relevant at any particular time, including, without limitation, market conditions, share price and future outlook.

In May 2017, the Board of Directors of Match Group authorized Match Group to repurchase up to 6 million shares of its common stock. Match Group has not repurchased any shares related to this repurchase authorization.

IAC's consolidated cash and cash equivalents at September 30, 2017 were $1.3 billion, of which $157.6 million was held by Match Group and $59.5 million was held by ANGI Homeservices. The Company generated $297.6 million of operating cash flows for the nine months ended September 30, 2017, of which $229.6 million was generated by Match Group and $52.0 million was generated by ANGI Homeservices. Each of Match Group and ANGI Homeservices are separate and distinct legal entities with their own public shareholders and board of directors and has no obligation to provide the Company with funds. As a result, we cannot freely access the cash of Match Group and ANGI Homeservices and their respective subsidiaries. In addition, agreements governing Match Group's indebtedness limit the payment of dividends or distributions and loans or advances to stockholders, including the Company, in the event a default has occurred or Match Group's leverage ratio (as defined in the Match Group Indentures) exceeds 5.0 to 1.0. In addition, the agreement governing ANGI Homeservices’ Term Loan limit the payment of dividends or distributions in the event a default has occurred or ANGI Homeservices’ leverage ratio (as defined therein) exceeds 4.0 to 1.0.

The Company anticipates that it will need to make capital and other expenditures in connection with the development and expansion of its operations. The Company's 2017 capital expenditures are expected to be higher than 2016 by approximately 5% to 10%, driven, in part, by ANGI Homeservices' sales center and corporate headquarters expansion and the Company's purchase of a 50% ownership interest in an aircraft in the second quarter of 2017 for approximately $16 million. This aircraft will replace the older of the Company's two existing jointly-owned aircrafts, which is currently being marketed for sale.

The Company has granted stock options and stock settled stock appreciation rights denominated in the equity of its subsidiaries to employees and management of certain subsidiaries. These equity awards vest over a period of years or upon the occurrence of certain prescribed events. The value of the stock options and stock settled stock appreciation rights is tied to the value of the common stock of these subsidiaries. Accordingly, these interests only have value to the extent the relevant business appreciates in value above the initial value utilized to determine the exercise price. These interests can have significant value in the event of significant appreciation. The interests are ultimately settled in IAC common stock with fair market value generally determined by negotiation or arbitration. These equity awards are settled on a net basis, with the award holder entitled to receive a payment in shares equal to the intrinsic value of the award at exercise less an amount equal to the required cash tax withholding payment. The number of shares ultimately needed to settle these awards may vary significantly as a result of both movements in our stock price and a determination of fair value of the relevant subsidiary that is different than our estimate.

In July 2017, Tinder, Inc. (“Tinder”) was merged into Match Group and as a result, all Tinder denominated equity awards were converted into Match Group tandem stock options ("tandem awards"), which can be exercised on a gross or net basis at the election of the award holder. If exercised on a gross basis, the award holder receives Match Group shares. If exercised on a net basis, the award holder receives IAC or Match Group shares, at IAC's election. In the event that IAC common shares are issued in settlement, Match Group will issue its common shares or pay cash to IAC as reimbursement for the IAC common

63

shares issued to the award holders pursuant to the Employee Matters Agreement. All of the Match Group tandem awards that were exercised during the third quarter of 2017 were exercised on a net basis and were settled in IAC common shares. The Company issued 1.9 million shares of its common stock to settle these awards and Match Group issued 10.6 million shares of its common stock to IAC as reimbursement. During the third quarter of 2017, Match Group also purchased certain fully vested tandem awards. During the third quarter of 2017, Match Group made cash payments of approximately $500 million to cover both the withholding taxes paid on behalf of employees who exercised these awards and the purchase of certain fully vested awards. Match Group will recognize a corporate income tax deduction based on the tax benefit of the intrinsic value of the awards exercised during the third quarter of 2017, however, there will be some delay in the timing of the realization of the cash benefit of the income tax deduction because it will be dependent upon the amount and timing of future taxable income and the timing of estimated income tax payments. At September 30, 2017, approximately 80% of the tandem awards was exercised.

In connection with the Combination, previously issued stock appreciation rights that related to common stock of HomeAdvisor (US) were converted into stock appreciation rights that are exercisable for Class A shares of ANGI Homeservices. IAC has the right to settle these awards using shares of IAC common stock. To the extent shares of IAC common stock are issued in settlement of these awards, ANGI Homeservices will reimburse IAC by issuing to IAC additional Class B shares of ANGI Homeservices common stock pursuant to the Employee Matters Agreement.

The Company currently expects to settle a sufficient number of exercises in IAC shares to maintain an economic interest in both Match Group and ANGI Homeservices of at least 80%.

The Company believes its existing cash, cash equivalents and expected positive cash flows generated from operations will be sufficient to fund our normal operating requirements, including capital expenditures, debt service, the payment of withholding taxes on behalf of employees for net-settled stock-based awards, and investing and other commitments for the foreseeable future. The Company's liquidity could be negatively affected by a decrease in demand for our products and services. The Company’s indebtedness could limit our ability to: (i) obtain additional financing to fund working capital needs, acquisitions, capital expenditure or debt service or other requirements; and (ii) use operating cash flow to make acquisitions, capital expenditures, invest in other areas, such as developing properties and exploiting business opportunities, in the event a default has occurred or in certain circumstances our leverage ratio (as defined in the credit agreement) exceeds 3.25 to 1.0. The Company may make additional acquisitions and investments and, as a result, the Company may need to raise additional capital through future debt or equity financing to provide for greater financial flexibility. Additional financing may not be available at all or on terms favorable to us.

Item 4.    Controls and Procedures

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

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

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

PART II

OTHER INFORMATION

Item 1. Legal Proceedings

Overview

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

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

Securities Class Action Litigation against Match Group

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

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

68

On July 27, 2016, the parties submitted to the Court a joint status report proposing a schedule for the plaintiffs’ filing of a consolidated amended complaint and the parties’ briefing of the defendants’ contemplated motion to dismiss the consolidated complaint. On August 17, 2016, the Court issued an order approving the parties’ proposed schedule.  On September 9, 2016, in accordance with the schedule, the plaintiffs filed an amended consolidated complaint.  The amended pleading focused solely on allegedly misleading statements or omissions concerning the Match Group’s Non-dating business. The defendants filed motions to dismiss the amended consolidated complaint on November 8, 2016. The plaintiffs filed oppositions to the motions on December 23, 2016, and the defendants filed replies to the oppositions on February 6, 2017.  On September 27, 2017, the court issued an opinion and order: (i) denying, without prejudice to renewal, the defendants’ motions and (ii) directing the plaintiffs to file a further amended pleading addressing the deficiencies in the amended consolidated complaint that were identified in the defendants’ motions. On October 30, 2017, the plaintiffs filed a second amended consolidated complaint, which among other things, dropped their claim under Section 12 of the Securities Act of 1933. Pursuant to an agreed-upon briefing schedule approved by the court, the defendants intend to file motions to dismiss the second amended consolidated complaint by December 14, 2017. We and Match Group believe that the allegations in this lawsuit, and the material allegations and claims therein, are without merit and intend to continue to defend against them vigorously.

Securities Class Action Litigation Challenging HomeAdvisor’s Combination with Angie’s List

On July 18, 2017, a purported shareholder class action was filed in federal court in Indianapolis against Angie’s List, the members of its board of directors, the Company and two related corporate entities, asserting violations of the federal securities laws based upon alleged material omissions from the registration statement related to the proposed combination of the HomeAdvisor and Angie’s List businesses into a single, publicly traded company.  See Parshall v. Angie’s List, Inc. et al., No. 1:17-cv-2418 (U.S. District Court, Southern District of Indiana).  On July 20, 2017, a second, substantially similar purported shareholder class action was filed in the same court. See Pill v. Angie’s List, Inc. et al., No. 1:17-cv-2461 (U.S. District Court, Southern District of Indiana). On September 11, 2017, a third, substantially similar purported shareholder class action was filed in the same court. See Chojar v. Angie’s List, Inc. et al., No. 1:17-cv-3208 (U.S. District Court, Southern District of Indiana). The gravamen of the complaints in these lawsuits is that the registration statement was materially misleading to shareholders of Angie’s List because it omitted: (i) certain financial projections, assumptions and other information relied upon by Angie’s List’s financial advisors in rendering their fairness opinions with respect to the proposed combination, (ii) certain information about Angie’s List’s board members’ potential conflicts of interest and (iii) certain information about the background of the transaction. The complaints asserted violations of Sections 14-a and 20-a of the Securities Exchange Act of 1934 and sought to enjoin the transaction, require the issuance of a revised registration statement and rescind the transaction and obtain damages should it go forward. On September 19, 2017: (i) the parties in these three lawsuits entered into a memorandum of understanding in which the plaintiffs agreed to dismiss their claims in exchange for the filing by Angie’s List of agreed-upon supplemental disclosures to the registration statement, with the court in Parshall case to retain jurisdiction for purposes of adjudicating the anticipated application by plaintiffs’ counsel for a mootness fee award, and (ii) Angie’s List filed the agreed-upon supplemental disclosures on a Form 8-K. In accordance with the parties’ memorandum of understanding, the plaintiffs filed notices of dismissal with prejudice in the Parshall, Pill, and Chojar cases on September 29, October 2, and September 29, 2017, respectively.

Item 1A.    Risk Factors

Cautionary Statement Regarding Forward-Looking Information

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

Actual results could differ materially from those contained in these forward-looking statements for a variety of reasons, including, among others: changes in senior management at IAC and/or its businesses, changes in our relationship with, or policies implemented by, Google, adverse changes in economic conditions, either generally or in any of the markets in which IAC's businesses operate, adverse trends in any of the industries in which IAC's businesses operate, our dependence on third parties in connection with the distribution and use of our products and services, our ability to offer new or alternative products

69

and services in a cost-effective manner and consumer acceptance of these products and services, our ability to attract and convert visitors to our various websites into users and customers, our ability to build, maintain and/or enhance our various brands, foreign exchange currency rate fluctuations, our ability to develop and monetize mobile versions of our various products and services, changes in industry standards and technology, the integrity and scalability of our systems and infrastructure (and those of third parties), our ability to protect our systems from cyberattacks and to protect personal and confidential user information, our ability to service our outstanding indebtedness and access to cash without adversely affecting our operations, dilution with respect to our investments in Match Group, Inc. and ANGI Homeservices Inc., operational and financial risks relating to acquisitions, our ability to successfully integrate Angie's List, our ability to expand successfully into international markets and regulatory changes. Certain of these and other risks and uncertainties are discussed in IAC's filings with the SEC, including in Part I "Item 1A. Risk Factors" of our Annual Report on Form 10-K for the fiscal year ended December 31, 2016. Other unknown or unpredictable factors that could also adversely affect IAC's business, financial condition and operating results may arise from time to time. In light of these risks and uncertainties, the forward-looking statements discussed in this report may not prove to be accurate. Accordingly, you should not place undue reliance on these forward-looking statements, which only reflect the views of IAC management as of the date of this quarterly report. IAC does not undertake to update these forward-looking statements.

Item 2.    Unregistered Sales of Equity Securities and Use of Proceeds

Unregistered Sales of Equity Securities

Except as described immediately below, during the quarter ended September 30, 2017, the Company did not issue or sell any shares of its common stock or any other equity securities pursuant to unregistered transactions.

In connection with the Combination and in consideration for the transfer by USANi LLC, a wholly-owned subsidiary of the Company ("USANi"), to the Company of all common membership units of HomeAdvisor International, LLC held by USANi, on September 29, 2017, the Company issued a total of 67,633 shares of Series C Cumulative Preferred Stock to USANi. This issuance was exempt from registration pursuant to Section 4(a)(2) of the Securities Act.

Issuer Purchases of Equity Securities

The Company did not purchase any shares of its common stock during the quarter ended September 30, 2017. As of that date, 8,580,742 shares of common stock remained available for repurchase under the Company's previously announced May 2016 repurchase authorization. IAC may purchase shares pursuant to this repurchase authorization over an indefinite period of time in the open market and in privately negotiated transactions, depending on those factors IAC management deems relevant at any particular time, including, without limitation, market conditions, share price and future outlook.

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

9 Months Ended

Sep. 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 Vimeo, Dotdash (formerly About.com), Dictionary.com, The Daily Beast and Investopedia, along with ANGI Homeservices Inc., which operates HomeAdvisor and Angie's List, 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 September 29, 2017, the Company completed its previously announced combination (the "Combination") of the businesses in the Company's HomeAdvisor segment and Angie's List, Inc. ("Angie's List") under a new publicly traded company called ANGI Homeservices Inc. ("ANGI Homeservices"). At September 30, 2017, IAC owned 87.1% and 98.5% of the economic and voting interest, respectively, of ANGI Homeservices. See "Note 3—Business Combination" for further information. In connection with the transaction, the Company changed the name of the HomeAdvisor segment to ANGI Homeservices and year-over-year comparisons for financial results for this segment are to the historical results of the HomeAdvisor segment (adjusted to reflect corporate allocations from IAC).

In connection with the Combination and in consideration for the transfer by USANi LLC, a wholly-owned subsidiary of the Company ("USANi"), to the Company of all common membership units of HomeAdvisor International, LLC held by USANi, on September 29, 2017, the Company issued a total of 67,633 shares of Series C Cumulative Preferred Stock (the “Series C Preferred Stock”) to USANi. The Company established the Series C Preferred Stock, par value $0.01 per share, on September 28, 2017. The Series C Preferred Stock is entitled to receive a cash dividend of $75.00 per share per annum, payable quarterly in arrears. The outstanding Series C Preferred Stock eliminates in the Company's consolidated financial statements.

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.

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.

In management's opinion, the unaudited interim consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and reflect all adjustments, consisting of normal and recurring adjustments, necessary for the fair presentation of our financial position, results of operations and cash flows for the periods presented. Interim results are not necessarily indicative of the results that may be expected for the full year. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the audited 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 recoverability of goodwill and indefinite-lived intangible assets; the useful lives and recoverability of definite-lived intangible assets and property and equipment; the fair value of long-term investments; 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 nine months endedSeptember 30, 2017, revenue from Google represents 21% and 23%, respectively, of the Company's consolidated revenue. For the three and nine months endedSeptember 30, 2016, revenue from Google represents 23% and 27%, respectively, of the Company's consolidated revenue.

The services agreement became effective on April 1, 2016, following the expiration of the previous services agreement, and expires on March 31, 2020; however, the Company may choose to terminate the agreement effective March 31, 2019. The services agreement requires that the Company 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 nine months endedSeptember 30, 2017, revenue earned from Google was $176.8 million and $539.2 million, respectively. For the three and nine months endedSeptember 30, 2016, revenue earned from Google was $172.0 million and $638.2 million, respectively. This revenue is earned by the businesses comprising the Applications and Publishing segments. For the three and nine months endedSeptember 30, 2017, revenue earned from Google represents 82% and 83% of Applications revenue and 72% and 71% of Publishing revenue. For the three and nine months endedSeptember 30, 2016, revenue earned from Google represents 85% and 87% of Applications revenue and 66% and 76% of Publishing revenue, respectively. Accounts receivable related to revenue earned from Google totaled $62.0 million and $65.8 million at September 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, 2016 and 2017; these amendments provide further revenue recognition guidance related to principal versus agent considerations, performance obligations and licensing, 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 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 Company’s assessment of the accounting for mobile app store fees incurred by Match Group in connection with obtaining members is still preliminary and ongoing. Match Group currently capitalizes these costs and amortizes them over the period of the applicable membership periods, which generally range from one to six months. The Company’s initial conclusions in applying ASU No. 2014-09 to these costs were: (1) these costs represent the incremental direct costs of obtaining a membership contract and (2) would, therefore, continue to be capitalized and amortized as incurred. The Company is reassessing this conclusion in light of its finding that there are divergent and evolving interpretations of the correct application of ASU No. 2014-09 to these costs. The total capitalized mobile app store fees were $19.8 million as of September 30, 2017.

• Within ANGI Homeservices, the effect of the adoption of ASU No. 2014-09 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. Prior to the Combination, Angie's List capitalized sales commissions and amortized the cost over the term of the applicable advertising contract. Following the Combination, Angie's List accounting policies will be conformed to the Company's accounting policies and these costs will be expensed as incurred. Following the adoption of ASU No. 2014-09, these costs will be capitalized and amortized over the average life of a service professional.

• Within Applications, the primary effect of the adoption of ASU No. 2014-09 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.

The Company does not expect the adoption of ASU No. 2014-09 to have a material effect 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 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 will adopt ASU No. 2016-02 effective January 1, 2019. The Company is currently evaluating the impact the adoption of this standard update will have on its consolidated financial statements.

Accounting Pronouncements adopted by the Company

In 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 early adopted the provisions of ASU No. 2017-09 during the third quarter of 2017 and the adoption of this standard update did not have a material impact on its consolidated financial statements.

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 nine months ended September 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 nine months ended September 30, 2017 were $314.3 million. Excess tax benefits of $43.1 million for the nine months ended September 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 1.1 million and 2.0 million shares for the three and nine months endedSeptember 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 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 nine months endedSeptember 30, 2017, the Company recorded an income tax benefit of $279.5 million and $322.8 million, respectively. The income tax benefit for the three and nine months endedSeptember 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 exercise, purchase or settlement of stock-based awards of $314.3 million for the nine months ended September 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 nine months endedSeptember 30, 2016, the Company recorded an income tax provision of $17.8 million and an income tax benefit of $77.4 million, respectively, which represents effective income tax rates of 25% and 37%, respectively. The effective tax rate for the three months ended September 30, 2016 is lower than the statutory rate of 35% due primarily to foreign income taxed at lower rates. The effective tax rate for the nine months ended September 30, 2016 is higher than the statutory rate of 35% due primarily to foreign income taxed at lower rates, state taxes and the non-taxable gain on the sale of PriceRunner, partially offset by the non-deductible portion of the goodwill impairment at the Publishing segment.

The Company recognizes interest and, if applicable, penalties related to unrecognized tax benefits in the income tax provision. At September 30, 2017 and December 31, 2016, the Company has accrued $3.3 million and $2.6 million, respectively, for the payment of interest. At both September 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 2013 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 September 30, 2017 and December 31, 2016, unrecognized tax benefits, including interest and penalties, are $43.0 million and $41.0 million, respectively. If unrecognized tax benefits at September 30, 2017 are subsequently recognized, $39.4 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 $22.5 million by June 30, 2018, due to expirations of statutes of limitations; $22.0 million of which would reduce the income tax provision.

The Company regularly assesses the realizability of deferred tax assets considering all available evidence including, among other things, the nature, frequency and severity of prior cumulative losses, forecasts of future taxable income, the duration of statutory carryforward periods, available tax planning and historical experience, to the extent these items are applicable. As of September 30, 2017, the Company has a gross deferred tax asset of $221.5 million that the Company expects to fully utilize on a more likely than not basis.

BUSINESS COMBINATION

Business Combinations [Abstract]

BUSINESS COMBINATION

BUSINESS COMBINATION

On September 29, 2017, the Company completed its previously announced combination of the businesses in the Company's HomeAdvisor segment and Angie's List under a new publicly traded company called ANGI Homeservices. Through the Combination, ANGI Homeservices acquired 100% of the common stock of Angie's List on September 29, 2017 for a total purchase price valued at $781.4 million. Angie’s List is a nationwide marketplace for local services where consumers can research, hire, rate and review the providers of these services. Ratings and reviews assist members in identifying and hiring a provider for their local service needs. Angie’s List's services are provided in markets located across the continental United States.

The purchase price of $781.4 million was determined based on the sum of (i) the fair value of the 61.3 million shares of Angie's List common stock outstanding immediately prior to the Combination based on the closing stock price of Angie's List common stock on the NASDAQ on September 29, 2017 of $12.46per share; (ii) the cash consideration of$1.9 millionpaid to holders of Angie's List common stock who elected to receive$8.50 in cash per share; and (iii) the fair value of vested equity awards (including the pro rata portion of unvested awards attributable to pre-combination services) outstanding under Angie's List stock plans on September 29, 2017. Each stock option to purchase shares of Angie's List common stock that was outstanding immediately prior to the effective time of the Combination was, as of the effective time of the Combination, converted into an option to purchase (i) that number of Class A shares of ANGI Homeservices equal to the total number of shares of Angie's List common stock subject to such Angie's List option immediately prior to the effective time of the Combination, (ii) at a per-share exercise price equal to the exercise price per share of Angie's List common stock at which such Angie's List option was exercisable immediately prior to the effective time of the Combination. Each award of Angie's List restricted stock units that was outstanding immediately prior to the effective time of the Combination was, as of the effective time of the Combination, converted into an ANGI Homeservices restricted stock unit award with respect to a number of Class A shares of ANGI Homeservices equal to the total number of shares of Angie's List common stock subject to such Angie's List restricted stock unit award immediately prior to the effective time of the Combination.

The table below summarizes the purchase price:

	Angie's List
	(In thousands)
Class A common stock	$	763,684
Cash consideration for holders who elected to receive $8.50 in cash per share of Angie's List common stock	1,913
Fair value of vested and pro rata portion of unvested stock options attributable to pre-combination services	11,749
Fair value of the pro rata portion of unvested restricted stock units attributable to pre-combination services	4,038
Total purchase price	$	781,384

The financial results of Angie's List are included in the Company's consolidated financial statements, within the ANGI Homeservices segment, beginning September 29, 2017. For the three and nine months endedSeptember 30, 2017, the Company included $0.7 million of revenue and $20.0 million of net losses in its consolidated statement of operations related to Angie's List. The Company is in the process of completing its determination of the fair values of assets acquired and liabilities assumed and the preliminary fair values are subject to revision. These fair values are expected to be finalized in the fourth quarter of 2017.

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

	Angie's List
	(In thousands)
Cash and cash equivalents	$	44,270
Other current assets	10,641
Property and equipment	16,341
Goodwill	545,396
Intangible assets	317,300
Total assets	933,948
Deferred revenue	(32,130		)
Other current liabilities	(46,106		)
Long-term debt—related party	(61,498		)
Deferred income taxes	(11,478		)
Other long-term liabilities	(1,352		)
Net assets acquired	$	781,384

The purchase price was based on the expected financial performance of Angie's List, not on the value of the net identifiable assets at the time of combination. This resulted in a significant portion of the purchase price being attributed to goodwill because Angie's List is complementary and synergistic to the other North America businesses of ANGI Homeservices.

The preliminary estimated fair values of the identifiable intangible assets acquired at the date of combination are as follows:

	Angie's List
	(In thousands)		Weighted-average useful life (years)
Indefinite-lived trade names and trademarks	$	137,000	Indefinite
Service providers	90,500		3
Developed technology	63,900		6
Memberships	15,900		3
User base	10,000		1
Total identifiable intangible assets acquired	$	317,300

Other current assets, current liabilities and other long-term liabilities of Angie's List were reviewed and adjusted to their fair values at the date of combination, as necessary. The fair value of deferred revenue was determined using an income approach that utilized a cost to fulfill analysis. The fair values of trade names and trademarks were determined using an income approach that utilized the relief from royalty methodology. The fair values of developed technology and user base were determined using a cost approach that utilized the cost to replace methodology. The fair values of the service providers and memberships were determined using an income approach that utilized the excess earnings methodology. The valuations of deferred revenue and intangible assets incorporate significant unobservable inputs and require significant judgment and estimates, including the amount and timing of future cash flows, cost and profit margins related to deferred revenue 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 Angie's List as if the Combination had occurred on January 1, 2016. The unaudited 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 the results that would have been achieved had the Combination actually occurred on January 1, 2016. For the three and nine months endedSeptember 30, 2017, pro forma adjustments include (i) reductions in stock-based compensation expense of $85.1 million and $52.8 million, respectively, and transaction related costs of $22.1 million and $25.6 million, respectively, because they are one-time in nature and will not have a continuing impact on operations; and (ii) an increase in amortization of intangibles of $11.4 million and $34.4 million, respectively. The stock-based compensation expense is related to the modification of previously issued HomeAdvisor vested equity awards, which were converted into ANGI Homeservices' equity awards, and the acceleration of previously issued Angie's List equity awards held by employees terminated in connection with the Combination. The transaction related costs include severance and retention costs of $12.0 million related to the Combination. For the three and nine months endedSeptember 30, 2016, pro forma adjustments include a reduction in revenue of $5.0 million and $31.4 million, respectively, due to the write-off of deferred revenue at the date of acquisition as well as increases in stock-based compensation expense of $19.7 million and $51.4 million, respectively, and amortization of intangibles of $14.0 million and $42.1 million, respectively.

The additions primarily relate to the acquisitions of MyHammer Holding AG (included in the ANGI Homeservices segment) and VHX (included in the Video segment). The deductions primarily relate to the sales of PriceRunner and ShoeBuy (both included in the Other segment). During the second quarter of 2016, the Company recorded impairment charges related to the entire $275.4 million balance of the Publishing reporting unit goodwill. The goodwill impairment charge at Publishing was driven by the impact from the new Google services agreement, traffic trends and monetization challenges and the corresponding impact on the current estimate of fair value.

The September 30, 2017 and December 31, 2016 goodwill balance reflects accumulated impairment losses of $598.0 million, $529.1 million and $11.6 million at Publishing, Applications and Connected Ventures (included in the Video segment), respectively.

Intangible assets with indefinite lives are trade names and trademarks acquired in various acquisitions. At September 30, 2017 and December 31, 2016, intangible assets with definite lives are as follows:

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:

Contingent Consideration Arrangements

As of September 30, 2017, there is one contingent consideration arrangement related to a business acquisition. The maximum contingent payment related to this arrangement is $3.0 million and the gross fair value of this arrangement, before the unamortized discount, at September 30, 2017 is $2.1 million.

The sole remaining contingent consideration arrangement is based upon earnings performance. Previous contingent consideration arrangements were based upon earnings performance and/or operating metrics. The Company determined the fair value of the contingent consideration arrangement by using probability-weighted analyses to determine the amounts of the gross liability, and, because the arrangement was 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 fair values of the contingent consideration arrangements at both September 30, 2017 and December 31, 2016 reflect discount rates of 12%.

The fair value of contingent consideration arrangements is 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 September 30, 2017 and December 31, 2016 includes a current portion of $0.6 million and $33.4 million, respectively, and a non-current portion of $1.2 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 September 30, 2017 and December 31, 2016, the carrying values of the Company's investments accounted for under the cost method totaled $116.2 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:

	September 30, 2017						December 31, 2016
	Carrying Value			Fair Value			Carrying Value			Fair Value

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

^(a)  The Match Group Term Loan matures on November 16, 2022; provided that, if any of the Match Group 6.75% Senior Notes remain outstanding on the date that is 91 days prior to the maturity date of the Match Group 6.75% Senior Notes, the Match Group Term Loan maturity date shall be September 15, 2022, the date that is 91 days prior to the maturity date of the Match Group 6.75% Senior Notes.

Match Group Senior Notes

The Match Group 6.375% 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 Match Group 6.75% Senior Notes were issued on November 16, 2015, in exchange for a portion of the 4.75% Senior Notes (the "Match Exchange Offer"). At any time prior to December 15, 2017, the Match Group 6.75% 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 Match Group 6.375% and 6.75% 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 September 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 March 31, 2016, Match Group made a $10 million principal payment on the Match Group Term Loan. On June 1, 2016, the $400 million in proceeds from the Match Group 6.375% Senior Notes, described above, were used to repay 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 was due at maturity, was repriced. On August 14, 2017, the Match Group Term Loan was increased by $75 million. In addition, the outstanding balance of $425 million was repriced at LIBOR plus 2.50%, and the LIBOR floor was reduced to 0.00%. 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 interest rate on the Match Group Term Loan at September 30, 2017 is 3.81%. Interest payments are due at least quarterly 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 September 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 Match Group 6.75% and 6.375% Senior Notes to the extent of the value of the assets securing the borrowings under the Match Group Credit Agreement.

IAC Senior Notes

The 4.875% and 4.75% Senior Notes were issued by IAC on November 15, 2013 and December 21, 2012, respectively. The 4.875% and 4.75% Senior Notes are unconditionally guaranteed by certain wholly-owned domestic subsidiaries, which are designated as guarantor subsidiaries; neither Match Group, ANGI Homeservices nor any of their subsidiaries guarantee any debt of IAC, or in the case of Match Group and its subsidiaries are subject to any of the covenants related to such debt. The guarantor subsidiaries are the same for the 4.875% and 4.75% Senior Notes. See "Note 13—Guarantor and Non-guarantor Financial Information" for financial information relating to guarantor and non-guarantor subsidiaries.

For the nine months endedSeptember 30, 2017, the Company redeemed and repurchased $28.3 million of its 4.875% Senior Notes and repurchased $3.3 million of its 4.75% Senior Notes. For the nine months endedSeptember 30, 2016, the Company redeemed and repurchased $109.8 million of its 4.875% Senior Notes and repurchased $16.5 million of its 4.75% Senior Notes.

On October 2, 2017, a subsidiary of the Company issued $517.5 million aggregate principal amount of 0.875% Exchangeable Senior Notes due October 1, 2022, which are guaranteed by the Company. The proceeds from these notes were, in part, loaned to IAC, which repaid the outstanding balance of the 4.875% Senior Notes of $361.9 million. See "Note 14—Subsequent Events" for further information.

IAC Credit Facility

IAC has a $300.0 million revolving credit facility (the "IAC Credit Facility") that expires October 7, 2020. At September 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 4.875% and 4.75% Senior Notes and are also secured by the stock of certain of our domestic and foreign subsidiaries. The 4.875% and 4.75% Senior Notes rank equally with each other, and are subordinate to outstanding borrowings under the IAC Credit Facility to extent of the value of the assets securing such borrowings.

________________________

^(a)  The amount for the three and nine months endedSeptember 30, 2017 and for the three months endedSeptember 30, 2016 reflects the reduction in Match Group's earnings attributable to IAC from the assumed exercise of Match Group dilutive securities under the if-converted method. For the nine months endedSeptember 30, 2016, the impact on earnings related to 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)  Dilutive securities for the three and nine months endedSeptember 30, 2017, includes the impact from the assumed exercise of ANGI Homeservices dilutive securities under the if-converted method, as it is more dilutive for IAC to settle certain ANGI Homeservices equity awards. The impact on earnings of ANGI Homeservices dilutive securities is not applicable for priors prior to the Combination.

^(c)  If the effect is dilutive, weighted average common shares outstanding include the incremental shares that would be issued upon the assumed exercise of stock options and subsidiary denominated equity and vesting of restricted stock units ("RSUs"). For the three months endedSeptember 30, 2017, there were no potentially dilutive securities excluded from the calculation of diluted earnings per share. For the nine months endedSeptember 30, 2017 and three months endedSeptember 30, 2016, less than 0.1 million and 3.3 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive.

^(d)  For the nine months endedSeptember 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. Accordingly, the weighted average basic shares outstanding were used to compute the diluted earnings per share amount.

^(e)  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 the three and nine months endedSeptember 30, 2017 and three months endedSeptember 30, 2016, 0.3 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 reportable segments.

________________________

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

Loss Contingency [Abstract]

CONTINGENCIES

CONTINGENCIES

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

Subsequent Events [Abstract]

SUBSEQUENT EVENTS

SUBSEQUENT EVENTS

On October 2, 2017, IAC FinanceCo, Inc., a direct, wholly-owned subsidiary of the Company, completed a private offering of $517.5 million aggregate principal amount of its 0.875% Exchangeable Senior Notes due October 1, 2022 (the “0.875% Exchangeable Senior Notes”), with interest payable each April 1 and October 1, commencing on April 1, 2018. The 0.875% Exchangeable Senior Notes are guaranteed by the Company.

The net proceeds from the sale of the 0.875% Exchangeable Senior Notes were approximately $500.5 million, after deducting fees and expenses. The net proceeds from the offering were used to:

• pay the net premium of approximately $50.7 million on the exchangeable note hedge and warrant transactions; and

• loaned to IAC, which repaid the outstanding balance of the 4.875% Senior Notes of $361.9 million, plus accrued interest of $8.8 million. The 4.875% Senior Notes were called for redemption on October 2, 2017 and will be redeemed and canceled on November 30, 2017. In connection with the call for redemption, the Company satisfied and discharged that certain Indenture, dated as of November 15, 2013, by and among the Company, as issuer, the guarantors named therein and Computershare Trust Company, N.A., as trustee, relating to the 4.875% Senior Notes.

The exchange rate for the 0.875% Exchangeable Senior Notes is initially 6.5713 shares of the Company's common stock per $1,000 principal amount of the notes, which is equivalent to an initial exchange price of $152.18 per share of the Company's common stock. In connection with this debt offering, the Company purchased call options at $152.18 per share, covering the entire 3.4 million shares that would be issuable upon the conversion of the notes, and sold warrants for 3.4 million shares at $229.70 per share. The exchangeable note hedge transactions are expected to reduce the potential dilutive effect of the Company's common stock upon any exchange of notes and/or offset any cash payment IAC FinanceCo, Inc. is required to make in excess of the principal amount of the exchanged notes. The warrants could separately have a dilutive effect on the Company's common stock to the extent that the market price per share of the Company common stock (as measured over the measurement period at the maturity of the warrants) exceeds the applicable strike price of the warrants.

On October 2, 2017, IAC Group, LLC, a wholly-owned subsidiary of the Company, entered into a joinder agreement by and among IAC Group, the Company, and each of the other loan parties party to the IAC Credit Facility. Pursuant to the joinder agreement, IAC Group became the successor borrower under the IAC Credit Facility and IAC's obligations under the credit agreement were terminated.

On October 23, 2017, the Company, through Match Group, sold its largest cost method investment, Zhenai Inc., a leading provider of online dating and matchmaking services in China. The net proceeds from the sale were $60.2 million.

On November 1, 2017, ANGI Homeservices entered into a credit agreement which provides for a five-year term loan A facility of $275 million ("ANGI Homeservices Term Loan"). The ANGI Homeservices Term Loan is guaranteed by ANGI Homeservices' wholly-owned material domestic subsidiaries and is secured by substantially all assets of ANGI Homeservices and the guarantors, subject to certain exceptions. The ANGI Homeservices Term Loan currently bears interest at LIBOR plus 200 basis points, which is subject to change based on the borrower's consolidated net leverage ratio. Interest payments are due at least quarterly through the term of the loan. The ANGI Homeservices Term Loan also requires quarterly amortization payments of 1.25% of the original principal amount thereof in the first three years, 2.5% in the fourth year and 3.75% thereafter. A portion of the proceeds of the loan were used to repay the Intercompany Notes and the remaining proceeds will be used for general corporate purposes. See "Note 12—Related Party Transactions with ANGI Homeservices" for further information on the Intercompany Notes outstanding between ANGI Homeservices and the Company.

In management's opinion, the unaudited interim consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and reflect all adjustments, consisting of normal and recurring adjustments, necessary for the fair presentation of our financial position, results of operations and cash flows for the periods presented. Interim results are not necessarily indicative of the results that may be expected for the full year. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the audited 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 recoverability of goodwill and indefinite-lived intangible assets; the useful lives and recoverability of definite-lived intangible assets and property and equipment; the fair value of long-term investments; 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 nine months endedSeptember 30, 2017, revenue from Google represents 21% and 23%, respectively, of the Company's consolidated revenue. For the three and nine months endedSeptember 30, 2016, revenue from Google represents 23% and 27%, respectively, of the Company's consolidated revenue.

The services agreement became effective on April 1, 2016, following the expiration of the previous services agreement, and expires on March 31, 2020; however, the Company may choose to terminate the agreement effective March 31, 2019. The services agreement requires that the Company 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, 2016 and 2017; these amendments provide further revenue recognition guidance related to principal versus agent considerations, performance obligations and licensing, 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 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 Company’s assessment of the accounting for mobile app store fees incurred by Match Group in connection with obtaining members is still preliminary and ongoing. Match Group currently capitalizes these costs and amortizes them over the period of the applicable membership periods, which generally range from one to six months. The Company’s initial conclusions in applying ASU No. 2014-09 to these costs were: (1) these costs represent the incremental direct costs of obtaining a membership contract and (2) would, therefore, continue to be capitalized and amortized as incurred. The Company is reassessing this conclusion in light of its finding that there are divergent and evolving interpretations of the correct application of ASU No. 2014-09 to these costs. The total capitalized mobile app store fees were $19.8 million as of September 30, 2017.

• Within ANGI Homeservices, the effect of the adoption of ASU No. 2014-09 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. Prior to the Combination, Angie's List capitalized sales commissions and amortized the cost over the term of the applicable advertising contract. Following the Combination, Angie's List accounting policies will be conformed to the Company's accounting policies and these costs will be expensed as incurred. Following the adoption of ASU No. 2014-09, these costs will be capitalized and amortized over the average life of a service professional.

• Within Applications, the primary effect of the adoption of ASU No. 2014-09 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.

The Company does not expect the adoption of ASU No. 2014-09 to have a material effect 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 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 will adopt ASU No. 2016-02 effective January 1, 2019. The Company is currently evaluating the impact the adoption of this standard update will have on its consolidated financial statements.

Accounting Pronouncements adopted by the Company

In 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 early adopted the provisions of ASU No. 2017-09 during the third quarter of 2017 and the adoption of this standard update did not have a material impact on its consolidated financial statements.

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 nine months ended September 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 nine months ended September 30, 2017 were $314.3 million. Excess tax benefits of $43.1 million for the nine months ended September 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 1.1 million and 2.0 million shares for the three and nine months endedSeptember 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.

________________________

^(a)  The amount for the three and nine months endedSeptember 30, 2017 and for the three months endedSeptember 30, 2016 reflects the reduction in Match Group's earnings attributable to IAC from the assumed exercise of Match Group dilutive securities under the if-converted method. For the nine months endedSeptember 30, 2016, the impact on earnings related to 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)  Dilutive securities for the three and nine months endedSeptember 30, 2017, includes the impact from the assumed exercise of ANGI Homeservices dilutive securities under the if-converted method, as it is more dilutive for IAC to settle certain ANGI Homeservices equity awards. The impact on earnings of ANGI Homeservices dilutive securities is not applicable for priors prior to the Combination.

^(c)  If the effect is dilutive, weighted average common shares outstanding include the incremental shares that would be issued upon the assumed exercise of stock options and subsidiary denominated equity and vesting of restricted stock units ("RSUs"). For the three months endedSeptember 30, 2017, there were no potentially dilutive securities excluded from the calculation of diluted earnings per share. For the nine months endedSeptember 30, 2017 and three months endedSeptember 30, 2016, less than 0.1 million and 3.3 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive.

^(d)  For the nine months endedSeptember 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. Accordingly, the weighted average basic shares outstanding were used to compute the diluted earnings per share amount.

^(e)  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 the three and nine months endedSeptember 30, 2017 and three months endedSeptember 30, 2016, 0.3 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.

________________________

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