NOTE 1—THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

IAC is a leading media and Internet company composed of widely known consumer brands, such as Tinder, Match, PlentyOfFish and OkCupid, which are part of Match Group's online dating portfolio, and HomeAdvisor and Angie's List, which are operated by ANGI Homeservices, as well as Vimeo, Dotdash, Dictionary.com, The Daily Beast and Investopedia.

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

As of June 30, 2018, IAC’s economic and voting interest in Match Group were 81.2%, and 97.6%, respectively. All references to "Match Group" or "MTCH" in this report are to Match Group, Inc.

As of June 30, 2018, IAC’s economic and voting interest in ANGI Homeservices were 86.4%, and 98.5%, respectively. All reference to "ANGI Homeservices" or "ANGI" in this report are to ANGI Homeservices Inc.

Basis of Consolidation and Accounting for Investments

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

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.

Investments in equity securities, other than those of our consolidated subsidiaries and those accounted for under the equity method, are accounted for at fair value or under the measurement alternative upon the adoption of Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, on January 1, 2018, with changes recognized within other income (expense), net each reporting period. Under the measurement alternative, equity investments without readily determinable fair values are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Under the measurement alternative, the value of our equity securities without determinable fair values is generally determined based on a market approach as of the transaction date. An investment will be considered identical or similar if it has identical or similar rights to the equity investments held by the Company. The Company reviews impairment of our equity securities each reporting period when there are qualitative indicators that may indicate impairment. Once the qualitative indicators are identified and the fair value of the security is less than its carrying value, the Company will write down the security to its fair value and record the corresponding charge within other income (expense), net. See "Accounting Pronouncements adopted by the Company" below for further information.

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 included in the Company's Annual Report on Form 10-K for the year ended December 31, 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. Actual results could differ from these estimates.

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 values of marketable debt securities and equity securities without readily determinable fair values; 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; unrecognized tax benefits; the valuation allowance for deferred income tax assets; and the fair value of and forfeiture rates for stock-based awards, among others. The Company bases its estimates and judgments on historical experience, its forecasts and budgets and other factors that the Company considers relevant.

Certain Risks and Concentrations

A 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").

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. Google recently announced policy changes related to its Chrome browser, effective in September 2018, which could hurt the distribution of our desktop products through the Chrome Web Store and could impact revenue and profits of some of the businesses within our Applications segment. 

For the three and six months endedJune 30, 2018, revenue earned from Google was $204.9 million and $416.2 million, representing 19% and 20%, respectively, of the Company's consolidated revenue. For the three and six months ended June 30, 2017, revenue earned from Google was $174.6 million and $362.4 million, representing 23% and 24%, respectively, of the Company's consolidated revenue. This revenue is earned principally by the businesses comprising the Applications and Publishing segments. For the three and six months endedJune 30, 2018, revenue earned from Google represents 75% and 79%, respectively, of Applications revenue and 71% and 73%, respectively, of Publishing revenue. For both the three and six months ended June 30, 2017, revenue earned from Google represented 83% of Applications revenue and 70% of Publishing revenue. Accounts receivable related to revenue earned from Google totaled $73.4 million and $72.4 million at June 30, 2018 and December 31, 2017, respectively.

Recent Accounting Pronouncements

Accounting Pronouncements adopted by the Company

In May 2014, the FASB ASU No. 2014-09, Revenue from Contracts with Customers. ASU No. 2014-09 supersedes nearly all existing revenue recognition guidance under GAAP. The Company adopted ASU No. 2014-09 effective January 1, 2018 using the modified retrospective transition method for open contracts as of the date of initial application. The cumulative impact to the Company's retained earnings at January 1, 2018 was $40.2 million, of which $3.4 million was related to the Company's noncontrolling interest in ANGI; the adjustment to retained earnings was principally related to the Company’s ANGI Homeservices and Applications segments.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

• Within ANGI, the effect of the adoption of ASU No. 2014-09 is that commissions paid to employees pursuant to certain sales incentive programs, which represent the incremental direct costs of obtaining a service professional contract, are now capitalized and amortized over the estimated life of a service professional (also referred to as the estimated customer relationship period). These costs were expensed as incurred prior to January 1, 2018. The cumulative effect of the adoption of ASU No. 2014-09 was the establishment of a current and non-current asset for capitalized sales commissions of $29.7 million and $4.2 million, respectively, and a related deferred tax liability of $8.0 million, resulting in a net increase to retained earnings of $25.9 million on January 1, 2018.

• Within Applications, the primary effect of the adoption of ASU No. 2014-09 is to accelerate the recognition of the portion of the revenue of certain desktop applications sold by SlimWare that qualifies as functional intellectual property ("functional IP") under ASU No. 2014-09. This revenue was previously deferred and recognized over the applicable subscription term. The cumulative effect of the adoption of ASU No. 2014-09 for SlimWare was a reduction in deferred revenue of $20.3 million and the establishment of a deferred tax liability of $4.9 million, resulting in a net increase to retained earnings of $15.5 million on January 1, 2018.

The adoption of ASU No. 2014-09 will not have a material effect on the Company’s results of operations for the year ending December 31, 2018. See "Note 2—Revenue Recognition" for additional information on the impact to the Company.

The Company's disaggregated revenue disclosures are presented in "Note 10—Segment information."

In January 2016, the FASB issued ASU No. 2016-01, which updates certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Under ASU No. 2016-01, equity securities, other than those of our consolidated subsidiaries and those accounted for under the equity method, will be measured at fair value with changes in fair value recognized in the statement of operations each reporting period. ASU No. 2016-01 is effective for reporting periods beginning after December 15, 2017. There was no cumulative impact to the Company's consolidated financial statements upon adoption of ASU No. 2016-01 on January 1, 2018. The adoption of ASU No. 2016-01 increases the volatility of the Company's other income (expense), net as a result of the remeasurement of these instruments. For the three and six months endedJune 30, 2018, other income, net includes net unrealized gains related to certain equity securities that were adjusted to fair value in accordance with ASU No. 2016-01 of $126.4 million and $126.6 million, respectively. See "Note 6—Fair Value Measurements and Financial Instruments" for additional information.

In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash, which requires companies to explain the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. Therefore, amounts generally described as restricted cash or restricted cash equivalents are combined with unrestricted cash and cash equivalents when reconciling the beginning and end of period balances on the statement of cash flows. ASU No. 2016-18 also requires companies to disclose the nature of their restricted cash and restricted cash equivalents balances. Additionally, when cash, cash equivalents, restricted cash, and restricted cash equivalents are presented within different captions on the balance sheet, a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet is required. ASU No. 2016-18 is effective for reporting periods beginning after December 15, 2017. The Company's adoption of ASU No. 2016-18 effective January 1, 2018, on a retrospective basis, did not have a material effect on its consolidated financial statements.

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balance sheet to the total amounts shown in the consolidated statement of cash flows:

	June 30, 2018		December 31, 2017		June 30, 2017		December 31, 2016
	(In thousands)
Cash and cash equivalents	$	1,644,829	$	1,630,809	$	1,522,300	$	1,329,187
Restricted cash included in other current assets	347		2,873		331		20,464
Restricted cash included in other assets	—		—		—		10,548
Total cash, cash equivalents and restricted cash as shown on the consolidated statement of cash flows	$	1,645,176	$	1,633,682	$	1,522,631	$	1,360,199

Restricted cash at December 31, 2017 primarily supports a letter of credit to a supplier, which was released to the Company in the second quarter of 2018.

Restricted cash at December 31, 2016 primarily included funds held in escrow for the redemption and repurchase of IAC Senior Notes and the MyHammer tender offer. In the first quarter of 2017, the Senior Notes were redeemed and repurchased and the funds held in escrow for the MyHammer tender offer were returned to the Company.

In June 2018, the FASB issued ASU No. 2018-07, Improvements to Nonemployee Share-Based Payment Accounting, which largely aligns the measurement and classification guidance for share-based payments granted to non-employees with the guidance for share-based payments granted to employees. The new guidance supersedes Subtopic 505-50, Equity - Equity-Based payments to Nonemployees. ASU No. 2018-07 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The Company adopted ASU No. 2018-07 effective April 1, 2018 and its adoption did not have a material effect on its consolidated financial statements. The effect of the adoption of ASU No. 2018-07 will be to minimize the volatility of expense related to stock-based awards to non-employees in the future.

Accounting Pronouncement not yet adopted by the Company

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. In July 2018, the FASB issued ASU No. 2018-11, which provides the option of an additional transition method that allows entities to initially apply the new lease guidance at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company expects to implement the transition method option provided by ASU No. 2018-11. The Company will adopt the new lease guidance effective January 1, 2019.

The Company is not a lessor, has no capitalized leases and does not expect to enter into any capitalized leases prior to the adoption of ASU No. 2016-02. Accordingly, the Company does not expect the amount or classification of rent expense in its statement of operations to be affected by the adoption of ASU No. 2016-02. The primary effect of the adoption of ASU No.

12

IAC/INTERACTIVECORP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

2016-02 will be the recognition of a right of use asset and related liability to reflect the Company's rights and obligations under its operating leases. The Company will also be required to provide the additional disclosures stipulated in ASU No. 2016-02.

The adoption of ASU No. 2016-02 will not have an impact on the leverage calculation set forth in any of the agreements governing the outstanding debt of the Company or its MTCH and ANGI subsidiaries, or our credit agreement or the credit agreement of MTCH because, in each circumstance, the leverage calculations are not affected by the liability that will be recorded upon adoption of the new standard.

While the Company's evaluation of the impact of the adoption of ASU No. 2016-02 on its consolidated financial statements continues, outlined below is a summary of the status of the Company's progress:

• the Company has selected a software package to assist in the determination of the right of use asset and related liability as of January 1, 2019 and to provide the required information following the adoption;

• the Company has prepared summaries of its leases for input into the software package;

• the Company is assessing the other inputs required in connection with the adoption of ASU No. 2016-02; and

• the Company is developing its accounting policy, procedures and controls related to the new standard.

The Company does not expect to have a preliminary estimate of the right of use asset and related liability as of the adoption date until the fourth quarter of 2018.

Reclassifications

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

NOTE 2—REVENUE RECOGNITION

General Revenue Recognition

The Company accounts for a contract when it has approval and commitment from all parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue is recognized when control of the promised services or goods is transferred to our customers, and in an amount that reflects the consideration the Company is contractually due in exchange for those services or goods.

Match Group

Match Group’s revenue is primarily derived directly from users in the form of recurring subscriptions. Subscription revenue is presented net of credits and credit card chargebacks. Subscribers pay in advance, primarily by credit card or through mobile app stores, and, subject to certain conditions identified in our terms and conditions, generally all purchases are final and nonrefundable. Revenue is initially deferred and is recognized using the straight-line method over the term of the applicable subscription period, which primarily range from one to six months. Revenue is also earned from online advertising, the purchase of à la carte features and offline events. Online advertising revenue is recognized when an advertisement is displayed. Revenue from the purchase of à la carte features is recognized based on usage. Revenue associated with offline events is recognized when each event occurs.

ANGI Homeservices

ANGI revenue is primarily derived from (i) consumer connection revenue, which comprises fees paid by service professionals for consumer matches (regardless of whether the professional ultimately provides the requested service), and (ii) membership subscription fees paid by service professionals. Consumer connection revenue varies based upon several factors, including the service requested, type of match and geographic location of service. The Company’s consumer connection revenue is generated and recognized when an in-network service professional is delivered a consumer match. Membership subscription revenue from service professionals is initially deferred and is recognized using the straight-line method over the

13

IAC/INTERACTIVECORP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

applicable subscription period, which is typically one year. Consumer connection revenue is generally billed one week following a consumer match; with payment due upon receipt of invoice.

ANGI revenue is also derived from Angie's List (i) sales of time-based website, mobile and call center advertising to service professionals and (ii) membership subscription fees from consumers. Angie's List service professionals generally pay for advertisements in advance on a monthly or annual basis at the option of the service professional, with the average advertising contract term being approximately one year. Angie's List website, mobile and call center advertising revenue is recognized ratably over the contract term. Revenue from the sale of advertising in the Angie’s List Magazine is recognized in the period in which the publication is distributed. Angie's List prepaid consumer membership subscription fees are recognized as revenue using the straight-line method over the term of the applicable subscription period, which is typically one year.

Video

Revenue of businesses in this segment is generated primarily through subscriptions, media production and distribution, and advertising. Subscription fee revenue is recognized over the terms of the applicable subscription period, which are one month or one year, production revenue is recognized when control is transferred to the customer to broadcast or exhibit, and advertising revenue is recognized when an advertisement is displayed or over the advertising period.

Applications

Applications' revenue largely consists of advertising revenue generated principally through the display of paid listings in response to search queries. The substantial majority of the paid listings displayed by our Applications businesses are supplied to us by Google pursuant to our services agreement with Google.

Pursuant to this agreement, those of our Applications businesses that provide search services transmit search queries to Google, which in turn transmits a set of relevant and responsive paid listings back to these businesses for display in search results. This ad-serving process occurs independently of, but concurrently with, the generation of algorithmic search results for the same search queries. Google paid listings are displayed separately from algorithmic search results and are identified as sponsored listings on search results pages. Paid listings are priced on a price per click basis and when a user submits a search query through one of our Applications businesses and then clicks on a Google paid listing displayed in response to the query, Google bills the advertiser that purchased the paid listing directly and shares a portion of the fee charged to the advertiser with us. The Company recognizes paid listing revenue from Google when it delivers the user's click. In cases where the user’s click is generated due to the efforts of a third-party distributor, we recognize the amount due from Google as revenue and record a revenue share or other payment obligation to the third-party distributor as traffic acquisition costs.

To a significantly lesser extent, Applications' revenue also consists of fees related to subscription downloadable desktop and mobile applications as well as display advertisements. Fees related to subscription downloadable desktop and paid mobile applications are generally recognized at the time of the sale when the software license is delivered. To the extent updates or maintenance is required or expected, revenue is recognized over the term of the applicable subscription period, which is primarily one or two years. Fees related to display advertisements are recognized when an advertisement is displayed.

Publishing

Publishing's revenue consists principally of advertising revenue, which is generated primarily through the display of paid listings in response to search queries and display advertisements (sold directly and through programmatic ad sales). The majority of the paid listings that our Publishing businesses display are supplied to us by Google in the manner, and pursuant to the services agreement with Google, described above under "Applications."

Transaction Price

The objective of determining the transaction price is to estimate the amount of consideration the Company is due in exchange for its services or goods, including amounts that are variable. The Company determines the total transaction price, including an estimate of any variable consideration, at contract inception and reassesses this estimate each reporting period.

14

IAC/INTERACTIVECORP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

The Company excludes from the measurement of transaction price all taxes assessed by governmental authorities that are both (i) imposed on and concurrent with a specific revenue-producing transaction and (ii) collected from customers. Accordingly, such tax amounts are not included as a component of revenue or cost of revenue.

For contracts that have an original duration of one year or less, the Company uses the practical expedient available under ASU No. 2014-09 applicable to such contracts and does not consider the time value of money.

Accounts Receivables, net of allowance for doubtful accounts and revenue reserves

Accounts receivable include amounts billed and currently due from customers. The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivables that will not be collected. The allowance for doubtful accounts is based upon a number of factors, including the length of time accounts receivable are past due, the Company’s previous loss history and the specific customer’s ability to pay its obligation. The time between the Company issuance of an invoice and payments due date is not significant; customer payments that are not collected in advance of the transfer of promised services or goods are generally due no later than 30 days from invoice date. The Company also maintains allowances to reserve for potential credits issued to consumers or other revenue adjustments. The amounts of these reserves are based primarily upon historical experience.

Deferred Revenue

Deferred revenue consists of advance payments that are received or due in advance of the Company's performance. The Company’s liabilities are reported on a contract by contract basis at the end of each reporting period. The Company generally classifies deferred revenue as current when the term of the applicable subscription period or expected completion of our performance obligation is one year or less. The deferred revenue balance as of January 1, 2018 is $332.2 million. During the three months endedJune 30, 2018, the Company recognized $224.0 million of revenue that was included in the deferred revenue balance as of April 1, 2018. During the six months endedJune 30, 2018, the Company recognized $278.8 million of revenue that was included in the deferred revenue balance as of January 1, 2018. The current and non-current deferred revenue balances at June 30, 2018 are $375.1 million and $2.0 million, respectively. Non-current deferred revenue is included in “Other long-term liabilities” in the accompanying consolidated balance sheet.

Arrangements with Multiple Performance Obligations

The Company’s contracts with customers may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on the prices charged to customers, which are directly observable or based on an estimate if not directly observable. For our multiple performance obligation arrangements that include functional intellectual property ("IP"), which comprise the downloadable apps and software of the Applications segment, the Company uses a residual approach to determine standalone selling prices for the functional IP.

Assets Recognized from the Costs to Obtain a Contract with a Customer

The Company has determined that certain costs, primarily commissions paid to employees pursuant to certain sales incentive programs and mobile app store fees, meet the requirements to be capitalized as a cost of obtaining a contract. Commissions paid to employees pursuant to certain sales incentive programs are amortized over the estimated customer relationship period. The Company calculates the estimated customer relationship period as the average customer life, which is based on historical data. When customer renewals are expected and the renewal commission is not commensurate with the initial commission, the average customer life includes renewal periods. For sales incentive programs where the customer relationship period is one year or less, the Company has elected the practical expedient to expense the costs as incurred. The Company generally capitalizes and amortizes mobile app store fees over the term of the applicable subscription.

During the three and six months endedJune 30, 2018, the Company recognized expense of $84.7 million and $159.8 million, respectively, related to the amortization of these costs. The contract asset balance at June 30, 2018 is $72.8 million.

Performance Obligations

As permitted under the practical expedient available under ASU No. 2014-09, the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts with variable consideration that is allocated entirely to unsatisfied performance obligations or to a wholly unsatisfied promise accounted for under the series guidance, and (iii) contracts for which the Company recognizes revenue at the amount which we have the right to invoice for services performed.

NOTE 3—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 unrecognized tax benefits is recognized in the interim period in which the change occurs.

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

For the three months ended June 30, 2018, the Company recorded an income tax provision of $31.4 million, which represents an effective income tax rate of 10%. The effective tax rate is lower than the statutory rate of 21% due primarily to excess tax benefits generated by the exercise and vesting of stock-based awards. For the six months endedJune 30, 2018, the Company recorded an income tax provision of $2.4 million, which represents an effective income tax rate of 1%. The effective tax rate is lower than the statutory rate of 21% due primarily to excess tax benefits generated by the exercise and vesting of stock-based awards. For the three and six months ended June 30, 2017, the Company recorded an income tax benefit, despite pre-tax income, of $19.4 million and $43.3 million, respectively, due primarily to excess tax benefits generated by the exercise and vesting of stock-based awards.

On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act subjected to U.S. taxation certain previously deferred earnings of foreign subsidiaries as of December 31, 2017 (“Transition Tax”) and implemented a number of changes that took effect on January 1, 2018, including but not limited to, a reduction of the U.S. federal corporate tax rate from 35% to 21% and a new minimum tax on global intangible low-taxed income (“GILTI”) earned by foreign subsidiaries. The Company was able to make a reasonable estimate of the Transition Tax and recorded a provisional tax expense in the fourth quarter of 2017. The Company was also able to make a reasonable estimate of the impact of GILTI on the expected annual effective income tax rate and recorded a tax expense for the three and six months ended June 30, 2018. Any adjustment of the Company’s provisional tax expense will be reflected as a change in estimate in its results in the period in which the change in estimate is made in accordance with Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, which is also included in the FASB issued ASU No. 2018-05, Income Taxes (Topic 740), Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118, whichwasissued and adopted by the Company in March 2018. The Company is continuing to gather additional information to more precisely compute the amount of the Transition Tax and expects to finalize its calculation prior to the filing of its U.S. federal tax return, which is due on October 15, 2018. The additional information includes, but is not limited to, the allocation and sourcing of income and deductions in 2017 for purposes of calculating the utilization of foreign tax credits. In addition, our estimates may also be impacted and adjusted as the law is clarified and additional guidance is issued at the federal and state levels. No adjustment was made in the three and six months ended June 30, 2018 to the Company’s previously recorded provisional tax expense, including for the impact of the issuance of Treasury Notices 2018-26 and 2018-28 as we continue to assess their impact, which we believe is immaterial.

The Company recognizes interest and, if applicable, penalties related to unrecognized tax benefits in the income tax provision. Accruals for interest and penalties are not material.

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 2016. The statute of limitations for the years 2010 through 2012 has been extended to June 30, 2019, and the statute of limitations for the years 2013 and 2014 has been extended to March 31, 2019. Various other jurisdictions are open to examination for tax years beginning with 2009. Income taxes payable include unrecognized tax benefits considered sufficient to pay assessments that may result from examination of prior year tax returns. We consider many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes. Although management currently believes changes in unrecognized tax benefits from period to period and differences between amounts paid, if any, upon resolution of issues raised in audits and amounts previously provided 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.

At June 30, 2018 and December 31, 2017, unrecognized tax benefits, including interest and penalties, are $40.5 million and $39.7 million, respectively. If unrecognized tax benefits at June 30, 2018 are subsequently recognized, $37.6 million, net of related deferred tax assets and interest, would reduce income tax expense. The comparable amount as of December 31, 2017 was $37.2 million. The Company believes that it is reasonably possible that its unrecognized tax benefits could decrease by $12.7 million by June 30, 2019, due to expirations of statutes of limitations; $12.4 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 June 30, 2018, the Company has a gross deferred tax asset of $125.0 million that the Company expects to fully utilize on a more likely than not basis.

NOTE 6—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:

18

IAC/INTERACTIVECORP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

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

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

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

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

Contingent Consideration Arrangements

As of June 30, 2018, there are three contingent consideration arrangements related to business acquisitions. Two of the contingent consideration arrangements have limits as to the maximum amount that can be paid. The maximum contingent payments related to these arrangements is $32.0 million and the gross fair value of these arrangements, before the unamortized discount, at June 30, 2018 is $2.0 million. No payment is expected for the one contingent consideration arrangement without a limit on the maximum earnout.

The contingent consideration arrangements are based upon earnings performance and/or operating metrics. The Company generally determines the fair value of the contingent consideration arrangements by using probability-weighted analyses to determine the amounts of the gross liability, and, because the arrangements were 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 June 30, 2018 and December 31, 2017 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 June 30, 2018 and December 31, 2017 includes a current portion of $1.9 million and $0.6 million, respectively, and non-current portion of $2.0 million at December 31, 2017, which are included in “Accrued expenses and other current liabilities” and “Other long-term liabilities,” respectively, in the accompanying consolidated balance sheet. At June 30, 2018, there is no non-current portion of the contingent consideration arrangement liability.

Equity securities without readily determinable fair values

At June 30, 2018 and December 31, 2017, the carrying values of the Company's investments in equity securities without readily determinable fair values totaled $216.2 million and $63.4 million, respectively, and are included in "Long-term investments" in the accompanying consolidated balance sheet. Following the adoption of the measurement alternative under ASU No. 2016-01 on January 1, 2018, the Company's equity securities without readily determinable fair values are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. All gains and losses on equity securities without readily determinable fair values, realized and unrealized, are recognized in "other income, net" in the accompanying consolidated statement of operations.

The following table presents a summary of realized and unrealized gains and losses recorded in other income (expense), net, as adjustments to the carrying value of equity securities without readily determinable fair values held as of June 30, 2018. The gross unrealized gains relate to the Company's remaining investments in an investee following the sale of a portion of the Company's investment during the second quarter of 2018.

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 method investments, are adjusted to fair value only when an impairment charge is recognized. The Company's financial assets, comprising equity securities without readily determinable fair values, are adjusted to fair value when observable price changes are identified or an impairment charge is recognized. Such fair value measurements are based predominantly on Level 3 inputs.

Financial instruments measured at fair value only for disclosure purposes

MTCH Senior Notes

The 6.375% MTCH Senior Notes were issued on June 1, 2016. The proceeds of $400 million were used to prepay a portion of indebtedness outstanding under the MTCH 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.

On December 4, 2017, MTCH issued $450 million aggregate principal amount of its 5.00% Senior Notes. The proceeds from these notes, along with cash on hand, were used to redeem the $445.2 million outstanding balance of the 6.75% MTCH Senior Notes, which were due on December 15, 2022, and pay the related call premium. At any time prior to December 15, 2022, the 5.00% MTCH 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.

23

IAC/INTERACTIVECORP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

The indentures governing the 6.375% and 5.00% MTCH Senior Notes (i) contain covenants that would limit MTCH's ability to pay dividends or to make distributions and repurchase or redeem MTCH stock in the event a default has occurred or MTCH's leverage ratio (as defined in the indentures) exceeds 5.0 to 1.0 and (ii) are ranked equally with each other. At June 30, 2018, there were no limitations pursuant thereto. There are additional covenants that limit MTCH's ability and the ability of its subsidiaries to, among other things, (i) incur indebtedness, make investments, or sell assets in the event MTCH is not in compliance with certain ratios set forth in the indentures, and (ii) incur liens, enter into agreements restricting MTCH subsidiaries' ability to pay dividends, enter into transactions with affiliates and consolidate, merge or sell substantially all of their assets.

MTCH Term Loan and MTCH Credit Facility

At both June 30, 2018 and December 31, 2017, the outstanding balance on the MTCH Term Loan was $425 million and the loan bears interest at LIBOR plus 2.50%. The interest rate of the MTCH Term Loan was 4.59% and 3.85% at June 30, 2018 and December 31, 2017, respectively. The MTCH Term Loan provides for 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 credit agreement. Interest payments are due at least quarterly through the term of the loan.

MTCH has a $500 million revolving credit facility (the "MTCH Credit Facility") that expires on October 7, 2020. At June 30, 2018 and December 31, 2017, there were no outstanding borrowings under the MTCH Credit Facility. The annual commitment fee on undrawn funds based on the current leverage ratio is 30 basis points. Borrowings under the MTCH Credit Facility bear interest, at MTCH'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 MTCH's consolidated net leverage ratio. The terms of the MTCH Credit Facility require MTCH 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 MTCH Credit Facility and the MTCH Term Loan that limit the ability of MTCH and its subsidiaries to, among other things, incur indebtedness, pay dividends or make distributions. While the MTCH Term Loan remains outstanding, these same covenants under its credit agreement are generally more restrictive than the covenants that are applicable to the MTCH Credit Facility. Obligations under the MTCH Credit Facility and MTCH Term Loan are unconditionally guaranteed by certain MTCH wholly-owned domestic subsidiaries, and are also secured by the stock of certain MTCH domestic and foreign subsidiaries. The MTCH Term Loan and outstanding borrowings, if any, under the MTCH Credit Facility rank equally with each other, and have priority over the 6.375% and 5.00% MTCH Senior Notes to the extent of the value of the assets securing the borrowings under the MTCH credit agreement.

ANGI Term Loan:

At June 30, 2018 and December 31, 2017, the outstanding balance on the ANGI Term Loan was $268.1 million and $275.0 million respectively. The ANGI Term Loan bears interest at LIBOR plus 2.00%, which is subject to change in future periods based on ANGI's consolidated net leverage ratio, and was 4.36% and 3.38% at June 30, 2018 and December 31, 2017, respectively. Interest payments are due at least quarterly through the term of the loan and quarterly principal payments of 1.25% of the original principal amount in the first three years, 2.5% in the fourth year and 3.75% in the fifth year are required.

The terms of the ANGI Term Loan require ANGI to maintain a consolidated net leverage ratio of not more than 4.5 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 credit agreement). There are additional covenants under the ANGI Term Loan that limit the ability of ANGI and its subsidiaries to, among other things, incur indebtedness, pay dividends or make distributions. The ANGI Term Loan is guaranteed by ANGI's wholly-owned material domestic subsidiaries and is secured by substantially all assets of ANGI and the guarantors, subject to certain exceptions.

IAC Exchangeable Notes:

On October 2, 2017, IAC FinanceCo, Inc., a direct, wholly-owned subsidiary of the Company, issued $517.5 million aggregate principal amount of its 0.875% Exchangeable Senior Notes (the “Exchangeable Notes”). The Exchangeable Notes are guaranteed by the Company. Each $1,000 of principal of the Exchangeable Notes is exchangeable for 6.5713 shares of the Company's common stock, which is equivalent to an exchange price of approximately $152.18 per share, subject to adjustment upon the occurrence of specified events. Upon exchange, the Company has the right to settle the principal amount of

24

IAC/INTERACTIVECORP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

Exchangeable Notes with any of the three following alternatives: (1) shares of our common stock, (2) cash or (3) a combination of cash and shares of our common stock.

The Exchangeable Notes are exchangeable at any time prior to the close of business on the business day immediately preceding July 1, 2022 only under the following circumstances: (1) during any calendar quarter (and only during such calendar quarter), if the last reported sale price of our common stock for at least 20 trading days during the period of 30 consecutive trading days during the immediately preceding calendar quarter is greater than or equal to 130% of the exchange price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the exchange rate on each such trading day; (3) if the issuer calls the notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events as further described under the indenture governing the Exchangeable Notes. On or after July 1, 2022 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may exchange all or any portion of their Exchangeable Notes regardless of the foregoing conditions.

A portion of the net proceeds from the sale of the Exchangeable Notes of $499.5 million, after deducting fees and expenses, was used to pay the net premium of $50.7 million on the Exchangeable Note Hedge and Warrant (defined below).

We separately account for the debt and the equity components of the Exchangeable Notes. Accordingly, the Company recorded a debt discount and corresponding increase to additional paid-in capital of $70.4 million, which is the fair value attributed to the exchange feature or equity component of the debt, on the date of issuance. The Company is amortizing the debt discount utilizing the effective interest method over the life of the Exchangeable Notes which increases the effective interest rate from its coupon rate of 0.875% to 3.88%.

In connection with the debt offering, the Company purchased call options allowing the Company to purchase initially (subject to adjustment upon the occurrence of specified events) the entire 3.4 million shares that would be issuable upon the exchange of the Exchangeable Notes at approximately $152.18 per share (the "Exchangeable Note Hedge"), and sold warrants allowing the holder to purchase initially (subject to adjustment upon the occurrence of specified events) 3.4 million shares at $229.70 per share (the "Warrant"). The Exchangeable Note Hedge is 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 would 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 exceeds the applicable strike price of the Warrants.

As of June 30, 2018, the if-converted value of the Exchangeable Notes exceeds its principal amount by $1.1 million based on the Company's stock price on June 30, 2018.

For the three and six months endedJune 30, 2018, the Company incurred interest expense of $5.3 million and $10.5 million, which includes amortization of original issue discount of $3.3 million and $6.5 million, and debt issuance costs of $0.8 million and $1.7 million, respectively. As of June 30, 2018, the unamortized discount is $60.7 million resulting in a net carrying value of the liability component of $456.8 million.

IAC Senior Notes

The 4.75% Senior Notes were issued by IAC on December 21, 2012. These Notes are unconditionally guaranteed by certain of our wholly-owned domestic subsidiaries, which are designated as guarantor subsidiaries. See "Note 13—Guarantor and Non-Guarantor Financial Information" for financial information relating to guarantor and non-guarantor subsidiaries. The 4.75% Senior 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.

IAC Credit Facility

IAC has a $300 million revolving credit facility (the "IAC Credit Facility") that expires October 7, 2020. At June 30, 2018 and December 31, 2017, there were no outstanding borrowings under the IAC Credit Facility. The annual commitment

fee on undrawn funds is 25 basis points, and is based on the leverage ratio (as defined in the agreement) 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 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 substantially the same domestic subsidiaries that guarantee the 4.75% Senior Notes and are also secured by the stock of certain of our domestic and foreign subsidiaries. The 4.75% Senior Notes are subordinate to the outstanding borrowings under the IAC Credit Facility to the extent of the value of the assets securing such borrowings.

________________________

^(a)  For the three and six months endedJune 30, 2018, it is more dilutive for IAC to settle certain MTCH and ANGI equity awards.  For the three and six months ended June 30, 2017, it is more dilutive for MTCH to settle certain MTCH equity awards.  The impact from ANGI’s dilutive securities is not applicable for periods prior to the Combination.

^(b)  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, warrants and subsidiary denominated equity, exchange of the Company's Exchangeable Notes and vesting of restricted stock units ("RSUs"). For the three and six months endedJune 30, 2018, 3.4 million and 6.9 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive. For the three and six months ended June 30, 2017, less than 0.1 million and 0.5 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive.

^(c)  Market-based awards and performance-based stock units (“PSUs”) are considered contingently issuable shares. Shares issuable upon exercise or vesting of market-based awards and PSUs are included in the denominator for earnings per share if (i) the applicable market or performance condition(s) has been met and (ii) the inclusion of the market-based awards and PSUs is dilutive for the respective reporting periods. For both the three and six months endedJune 30, 2018, 0.2 million shares underlying market-based awards and PSUs were excluded from the calculation of diluted earnings per share because the market or performance conditions had not been met. For both the three and six months ended June 30, 2017, 0.4 million shares underlying market-based awards and PSUs were excluded from the calculation of diluted earnings per share because the market or performance conditions had not been met.

^(d)  It is the Company's intention to settle the Exchangeable Notes through a combination of cash, equal to the face amount of the notes, and shares; therefore, the Exchangeable Notes are only dilutive for periods during which the average price of IAC common stock exceeds the approximate $152.18 per share exchange price per $1,000 principal amount of the Exchangeable Notes.

NOTE 10—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.

________________________

^(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 businesses, and this measure is one of the primary metrics on 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. 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 12—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 3—Income Taxes" for additional information related to income tax contingencies.

NOTE 13—GUARANTOR AND NON-GUARANTOR FINANCIAL INFORMATION

The 4.75% Senior Notes are unconditionally guaranteed, jointly and severally, by certain domestic subsidiaries which are 100% owned by the Company. The following tables present condensed consolidating financial information at June 30, 2018 and December 31, 2017 and for the three and six months endedJune 30, 2018 and 2017 for: IAC, on a stand-alone basis; the combined guarantor subsidiaries of IAC; the combined non-guarantor subsidiaries of IAC; and IAC on a consolidated basis.

Non-GAAP financial measure:

• Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization ("Adjusted EBITDA") - is a non-GAAP financial measure. See "Principles of Financial Reporting" for the definition of Adjusted EBITDA.

Certain Risks and Concentrations—Online Advertising

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").

47

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. Google recently announced policy changes related to its Chrome browser, effective in September 2018, which could hurt the distribution of our desktop products through the Chrome Web Store and could impact revenue and profits of some of the businesses within our Applications segment. 

For the three and six months endedJune 30, 2018, revenue earned from Google was $204.9 million and $416.2 million, representing 19% and 20%, respectively, of the Company's consolidated revenue. For the three and six months ended June 30, 2017, revenue earned from Google was $174.6 million and $362.4 million, representing 23% and 24%, respectively, of the Company's consolidated revenue. This revenue is earned principally by the businesses comprising the Applications and Publishing segments. For the three and six months endedJune 30, 2018, revenue earned from Google represents 75% and 79%, respectively, of Applications revenue and 71% and 73%, respectively, of Publishing revenue. For both the three and six months ended June 30, 2017, revenue earned from Google represented 83% of Applications revenue and 70% of Publishing revenue.

Second Quarter 2018 and Year to Date June 2018 Consolidated Results

For the three months ended June 30, 2018, the Company delivered 38% revenue growth, 123% operating income growth and 83% Adjusted EBITDA growth. Revenue increased $291.7 million due primarily to an increase from ANGI due, in part, to the Combination (defined below) of $114.1 million, growth from MTCH of $111.6 million, and increases from Publishing of $59.2 million and Video of $7.6 million. Operating income increased $92.8 million due primarily to the increase in Adjusted EBITDA of $120.5 million and a change of $2.9 million in acquisition-related contingent consideration fair value adjustments, partially offset by increases of $18.6 million in stock-based compensation expense and $11.6 million in amortization of intangibles both due, in part, to the Combination. The Adjusted EBITDA increase was primarily driven by growth from MTCH of $65.7 million, ANGI of $53.3 million, and Publishing of $11.0 million, partially offset by declines of $5.1 million from Applications and $4.3 million from Video.

For the six months ended June 30, 2018, the Company delivered 34% revenue growth, 129% operating income growth and 83% Adjusted EBITDA growth. The increases in revenue, operating income and Adjusted EBITDA are due primarily to the factors described above in the three-month discussion.

Events affecting year-over-year comparability include:

(i) the adoption of the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers, on January 1, 2018. For the three months ended June 30, 2018, the adoption of ASU No. 2014-09 decreased consolidated operating income by $0.6 million. For the six months ended June 30, 2018, the adoption of ASU No. 2014-09 increased consolidated operating income by $5.2 million, due primarily to a reduction in sales commissions expense of $8.2 million at ANGI due to the capitalization and amortization of sales commissions. For both the three and six months ended June 30, 2018, the effect of ASU No. 2014-09 on consolidated revenue was a decrease of $2.0 million.

(ii) the combination on September 29, 2017 of the businesses comprising the Company's former HomeAdvisor segment and Angie's List, Inc. ("Angie's List") under a new publicly traded company called ANGI Homeservices Inc. (the "Combination"), which comprises the Company's ANGI Homeservices segment. The Company expects the remaining transaction-related expenses, including deferred revenue write-offs, during 2018 to total approximately $2 million. Stock-based compensation expense related to the modification of previously issued HomeAdvisor equity awards and previously issued Angie's List equity awards, both of which were converted into ANGI Homeservices' equity awards in the Combination, is expected to be approximately $30 million for the remainder of 2018, and approximately $40 million in 2019 and $25 million in 2020.

(iii) the impact of moving Daily Burn from the Video segment to the Applications segment effective April 1, 2018.

(iv) the sale of The Princeton Review on March 31, 2017 (reflected in the Other segment).

48

(v) acquisitions in 2017:

• a controlling interest in HomeStars Inc. ("HomeStars") on February 8, 2017 (reflected in the ANGI Homeservices segment as part of the North America business);

• a controlling interest in MyBuilder Limited ("MyBuilder") on March 24, 2017 (reflected in the ANGI Homeservices segment as part of the Europe business); and

• Livestream on October 18, 2017 (reflected in the Video segment as part of Vimeo).

(vi) the adoption of FASB ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, on January 1, 2018. For the three and six months ended June 30, 2018, the adoption of ASU No. 2016-01 increased other income, net by $126.4 million and $126.6 million, respectively, which includes gross unrealized gains related to the remeasurement of Company's remaining investments in an investee following the sale of a portion of the Company's investment during the second quarter of 2018.

^* The Other segment consists of the results of The Princeton Review prior to its sale on March 31, 2017.

For the three months ended June 30, 2018 compared to the three months ended June 30, 2017

MTCH revenue increased 36% driven by International Direct Revenue growth of $64.6 million, or 53%, and North America Direct Revenue growth of $43.7 million, or 24%. Both International and North America Direct Revenue growth were driven by higher Average Subscribers, up 36% and 20%, respectively, due primarily to continued growth in Subscribers at Tinder. Total ARPU increased 8% due to Tinder, as Subscribers purchased premium and multi-tiered subscriptions as well as additional à la carte features. International ARPU also benefited from the weakening of the U.S. dollar relative to international foreign currencies.

ANGI revenue increased 63% driven by a full quarter contribution of $58.5 million from Angie's List, Marketplace growth of $49.0 million, or 31%, and growth of $2.1 million, or 14% at the European businesses. Marketplace Revenue growth was driven by a 30% increase in Marketplace Service Requests to 6.8 million and a 23% increase in Marketplace Paying SPs to 202,000. Revenue from Angie's List reflects a write-off of deferred revenue due to the Combination of $1.8 million. Revenue growth at the European businesses was driven by growth across all regions and benefited from the weakening of the U.S. dollar relative to the Euro and the British Pound.

Video revenue increased 14% driven by strong growth from Vimeo, which had ending subscribers of 917,000, an increase of 11% year-over-year, and the contribution from Lady Bird at IAC Films, which was released in the fourth quarter of 2017, partially offset by a decline at Electus and the transfer of Daily Burn to the Applications segment effective April 1, 2018. Vimeo revenue in 2018 also includes the contribution from Livestream.

Applications revenue decreased 1% due to a decrease of $6.6 million, or 25%, in Partnerships, partially offset by an increase of $5.7 million, or 5%, in Consumer. Partnerships revenue continued to decline, as expected, due primarily to the loss of certain partners. The Consumer revenue increase was driven primarily by mobile growth including Daily Burn, which moved from the Video segment effective April 1, 2018, partially offset by a decrease of 44% at SlimWare, due primarily to lower subscription revenue and lower revenue per query at the Consumer desktop applications business. The effect of the adoption of ASU No. 2014-09 resulted in a decrease in revenue of $2.5 million at SlimWare.

Publishing revenue increased 76% due to $47.8 million, or 96%, higher Ask & Other revenue and $11.4 million, or 40%, higher Premium Brands revenue. Ask & Other revenue increased due to growth in paid traffic primarily in international markets. Premium Brands revenue increased due to growth of 50% at Dotdash due to an increase in organic traffic and advertising revenue, growth of 47% at Investopedia and growth of 65% at The Daily Beast.

50

For the six months ended June 30, 2018 compared to the six months ended June 30, 2017

MTCH revenue increased 36% driven by International Direct Revenue growth of $133.6 million, or 57%, and North America Direct Revenue growth of $79.7 million, or 23%. Both International and North America Direct Revenue growth were due primarily to the factors described above in the three-month discussion.

ANGI revenue increased 66% driven by a full six months contribution of $116.4 million from Angie's List, Marketplace growth of $84.9 million, or 30%, and growth of $8.7 million, or 31% at the European businesses. Revenue growth for both Marketplace and the European business were due primarily to the factors described above in the three-month discussion. Marketplace Service Requests increased 33% to 11.8 million. Revenue from Angie's List reflects a write-off of deferred revenue due to the Combination of $4.6 million. Revenue growth at the European businesses was also driven by the acquisition of a controlling interest in MyBuilder on March 24, 2017.

Video revenue increased 22% driven by the factors described above in the three-month discussion.

Applications revenue decreased 9% due to decreases of $14.6 million, or 6%, in Consumer and $13.2 million, or 24%, in Partnership. The Consumer revenue decline was due primarily to lower revenue per query at the Consumer desktop applications business and a decrease of 29% at SlimWare, due primarily to lower subscription revenue, partially offset by mobile growth. The effect of the adoption of ASU No. 2014-09 resulted in a decrease in revenue of $3.1 million at SlimWare. Partnerships revenue continued to decline as expected due primarily to the loss of certain partners.

Publishing revenue increased 74% due to $91.3 million, or 90%, higher Ask & Other revenue and $24.2 million, or 45%, higher Premium Brands revenue. Revenue growth for both Ask & Other and Premium Brands were due primarily to the factors described above in the three-month discussion.

Cost of revenue in 2018 increased from 2017 due to increases of $36.4 million from Publishing, $34.7 million from MTCH and $7.1 million from ANGI.

• The Publishing increase was due primarily to an increase of $33.1 million in traffic acquisition costs driven by higher revenue at Ask & Other and an increase of $2.7 million in compensation expense.

• The MTCH increase was due primarily to an increase of $33.6 million in in-app purchase fees as revenues are increasingly sourced through mobile app stores.

• The ANGI increase was due primarily to increases of $2.4 million in traffic acquisition costs, $2.0 million in credit card processing fees due to $1.2 million from the inclusion of Angie's List and higher Marketplace Revenue, $1.2 million in hosting fees, primarily from the inclusion of Angie's List, and $0.8 million in costs associated with publishing and distributing the Angie's List Magazine.

Selling and marketing expense

Selling and marketing expense	$369,660	$49,556	15%	$320,104
As a percentage of revenue	35%			42%

Selling and marketing expense in 2018 increased from 2017 due to increases of $30.9 million from ANGI, $9.0 million from Publishing and $8.6 million from Video.

• The ANGI increase was due primarily to higher marketing expense of $14.1 million and an increase of $13.7 million in compensation expense, both reflecting the impact from the inclusion of Angie's List. The increase in marketing expense is due primarily to increased investments in online marketing and television spend. Compensation expense increased due primarily to growth in the sales force, partially offset by a reduction in sales commissions expense of $2.1 million due to the adoption of ASU No. 2014-09. As a percentage of revenue, selling and marketing expense declined due, in part, to accelerated revenue growth driven by capacity expansion efforts combined with marketing optimization efforts at HomeAdvisor.

• The Publishing increase was due primarily to higher marketing expense of $5.7 million, principally related to higher Ask & Other revenue, and an increase of $3.0 million in compensation expense due, in part, to an increase in the sales force at Investopedia and The Daily Beast, and an increase in severance.

• The Video increase was due primarily to an increase of $3.5 million in marketing expense at Vimeo, $3.1 million of expense from the inclusion of Livestream and higher compensation expense at Electus of $2.7 million, partially offset by a decrease of $1.4 million from Daily Burn, following its move to the Applications segment effective April 1, 2018.

52

Selling and marketing expense in 2018 increased from 2017 due to increases of $73.0 million from ANGI, $23.0 million from Publishing, $16.0 million from Video and $13.6 million from MTCH, partially offset by decreases of $16.2 million from Applications and $7.3 million from Other.

• The ANGI and Publishing increases were due primarily to the factors described above in the three-month discussion. Compensation expense at ANGI in 2018 reflects a reduction in sales commissions expense of $8.2 million due to the adoption of ASU No. 2014-09.

• The Video increase was due primarily to increases in marketing expense at both Vimeo and IAC Films of $6.3 million and $3.0 million, respectively, higher compensation expense at Electus and Vimeo of $5.8 million and $1.0 million, respectively, and $5.3 million of expense from the inclusion of Livestream, partially offset by a decrease of $5.9 million from Daily Burn, following its move to the Applications segment effective April 1, 2018.

• The MTCH increase was due primarily to higher marketing expense of $13.6 million. The increase in marketing expense is due primarily to an increase in investments in Tinder and Pairs and the launch of a new brand in Europe. As a percentage of revenue, selling and marketing expense decreased due primarily to the ongoing shift towards brands with lower relative marketing spend.

• The Applications decrease was due primarily to lower online marketing expense of $18.4 million at Consumer.

• The Other decrease was due to the sale of The Princeton Review.

General and administrative expense in 2018 increased from 2017 due to increases of $27.5 million from ANGI, $5.3 million from Corporate, $2.9 million from Applications and $2.5 million from Video.

• The ANGI increase was due primarily to higher compensation expense of $20.3 million. The increase in compensation expense was due primarily to an increase of $8.0 million in stock-based compensation expense, an increase in headcount following the Combination and existing business growth and the inclusion of $0.5 million in severance and retention costs in 2018 related to the Combination. The increase in stock-based compensation expense reflects $12.6 million in expense due to the modification of previously issued HomeAdvisor equity awards, which were converted into ANGI Homeservices' equity awards, and $2.2 million in expense related to previously issued Angie's List equity awards including the acceleration of certain converted equity awards resulting from the termination of Angie's List employees in connection with the Combination, partially offset by the inclusion in 2017 of a modification charge related to an equity award. General and administrative expense also includes increases of $3.3 million in bad debt expense due, in part, to higher Marketplace Revenue, and $2.9 million in software license and maintenance costs, reflecting the impact from the inclusion of Angie's List, partially offset by the inclusion in 2017 of $3.7 million of transaction-related costs related to the Combination.

• The Corporate increase was due primarily to a mark-to-market stock-based compensation expense adjustment.

• The Applications increase was due primarily to the inclusion in the second quarter of 2017 of a $2.9 million favorable legal settlement.

• The Video increase was due primarily to $2.0 million of expense from the inclusion of Livestream.

For the three months ended June 30, 2018 compared to the three months ended June 30, 2017

Operating income in 2018 increased from 2017 due primarily to the increase in Adjusted EBITDA of $120.5 million, described below, and a change of $2.9 million in acquisition-related contingent consideration fair value adjustments, partially offset by increases of $18.6 million in stock-based compensation expense, $11.6 million in amortization of intangibles and $0.5 million in depreciation. The increase in stock-based compensation expense was due primarily to an increase of $10.2 million at ANGI due primarily to the modification and acceleration charges related to the Combination. The increase in amortization of intangibles was due primarily to the Combination and the acquisition of Livestream, partially offset by a Publishing trade name that was fully amortized in 2017.

For the six months ended June 30, 2018 compared to the six months ended June 30, 2017

Operating income in 2018 increased from 2017 due primarily to the increase in Adjusted EBITDA of $207.0 million, described below, a change of $4.7 million in acquisition-related contingent consideration fair value adjustments and a decrease of $0.2 million in depreciation, partially offset by increases of $43.8 million in stock-based compensation expense and $22.4 million in amortization of intangibles. The increase in stock-based compensation expense was due primarily to an increase of $30.7 million at ANGI due primarily to the modification and acceleration charges related to the Combination. The increase in amortization of intangibles was due primarily to the factors described above in the three-month discussion.

At June 30, 2018, there was $385.4 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 2.3 years.

For a reconciliation of operating income (loss) for the Company's reportable segments and net earnings attributable to IAC's shareholders to Adjusted EBITDA, see "Note 10—Segment Information" to the consolidated financial statements included in "Item 1. Consolidated Financial Statements."

For the three months ended June 30, 2018 compared to the three months ended June 30, 2017

MTCH Adjusted EBITDA increased 60% due primarily to the increase of $111.6 million in revenue due to growth at Tinder, and lower operating expenses as a percentage of revenue, partially offset by higher in-app purchase fees as revenues are increasingly sourced through mobile app stores.

ANGI Adjusted EBITDA increased 390% due primarily to the increase of $114.1 million in revenue, which reflects the write-off of deferred revenue related to the Combination of $1.8 million, and lower selling and marketing expense as a percentage of revenue, partially offset by higher compensation expense due, in part, to increased headcount, following the Combination, and increases in software license and maintenance costs and bad debt expense and the inclusion in 2018 of $0.8 million of costs related to the Combination (including severance, retention and integration related costs). Transaction-related costs related to the Combination in 2017 were $3.7 million. Adjusted EBITDA in 2018 benefited from a reduction in sales commissions expense of $2.1 million due to the adoption of ASU No. 2014-09.

Video Adjusted EBITDA loss increased 63%, despite higher revenue, driven by higher losses from Electus and Vimeo, partially offset by profits at IAC Films. The increased Adjusted EBITDA loss at Vimeo, despite higher revenue, was driven by investments in product development and marketing expense to continue to grow the business.

Applications Adjusted EBITDA decreased 13% due primarily to lower revenue and the inclusion in the second quarter of 2017 of a $2.9 million favorable legal settlement, partially offset by lower online marketing spend and the contribution from Daily Burn, which moved from the Video segment effective April 1, 2018.

Publishing Adjusted EBITDA increased $11.0 million, due primarily to higher revenue and lower operating expenses as a percentage of revenue.

Corporate Adjusted EBITDA loss was flat.

For the six months ended June 30, 2018 compared to the six months ended June 30, 2017

MTCH Adjusted EBITDA increased 60% due primarily to the factors described above in the three-month discussion.

In the second quarter of 2018, the Company recorded an income tax provision of $31.4 million for an effective income tax rate of 10%, which is lower than the statutory rate of 21% primarily due to excess tax benefits generated by the exercise and vesting of stock-based awards. 

The 2017 income tax benefit, despite pre-tax income, was due primarily to excess tax benefits generated by the exercise and vesting of stock-based awards.

The 2017 income tax benefit is due primarily to the factors described above in the three-month discussion.

On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act subjected to U.S. taxation certain previously deferred earnings of foreign subsidiaries as of December 31, 2017 (“Transition Tax”) and implemented a number of changes that took effect on January 1, 2018, including but not limited to, a reduction of the U.S. federal corporate tax rate from 35% to 21% and a new minimum tax on global intangible low-taxed income (“GILTI”) earned by foreign subsidiaries. The Company was able to make a reasonable estimate of the Transition Tax and recorded a provisional tax expense in the fourth quarter of 2017. The Company was also able to make a reasonable estimate of the impact of GILTI on

59

the expected annual effective income tax rate and recorded a tax expense for the three and six months ended June 30, 2018. Any adjustment of the Company’s provisional tax expense will be reflected as a change in estimate in its results in the period in which the change in estimate is made in accordance with Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, which is also included in the FASB issued ASU No. 2018-05, Income Taxes (Topic 740), Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118,” whichwasissued and adopted by the Company in March 2018. The Company is continuing to gather additional information to more precisely compute the amount of the Transition Tax and expects to finalize its calculation prior to the filing of its U.S. federal tax return, which is due on October 15, 2018. The additional information includes, but is not limited to, the allocation and sourcing of income and deductions in 2017 for purposes of calculating the utilization of foreign tax credits. In addition, our estimates may also be impacted and adjusted as the law is clarified and additional guidance is issued at the federal and state levels. No adjustment was made in the three and six months ended June 30, 2018 to the Company’s previously recorded provisional tax expense, including for the impact of the issuance of Treasury Notices 2018-26 and 2018-28 as we continue to assess their impact, which we believe is immaterial.

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 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. The above items are excluded from our Adjusted EBITDA measure because these items are non-cash in nature. 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 six months ended June 30, 2018 and 2017, see "Note 10—Segment Information" to the consolidated financial statements included in "Item 1—Consolidated Financial Statements."

Non-Cash Expenses That Are Excluded From Non-GAAP Measure

Stock-based compensationexpense consists principally of expense associated with the grants, including unvested grants assumed in acquisitions (including the Combination), of stock options, restricted stock units ("RSUs"), performance-based RSUs and market-based awards. These expenses are not paid in cash, and we include the related shares in our fully diluted shares outstanding using the treasury stock method. 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). To the extent that stock-based awards are settled on a net basis, the Company remits the required tax-withholding amounts 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 (including the Combination). At the time of an acquisition, the identifiable definite-lived intangible assets of the acquired company, such as service professional relationships, technology, customer lists and user base, content, trade names and memberships, are valued and amortized over their estimated lives. Value is also assigned to acquired indefinite-lived intangible assets, which comprise trade names and trademarks, and goodwill that are not subject to amortization. An impairment is recorded when the carrying value of an intangible asset or goodwill exceeds its fair value. We believe that intangible assets represent costs incurred by the acquired company to build value prior to acquisition and the related amortization and impairment charges of intangible assets or goodwill, if applicable, are not ongoing costs of doing business.

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

IAC, MTCH and ANGI Long-term Debt

For a detailed description of IAC, MTCH and ANGI long-term debt, see "Note 7—Long-term Debt" to the consolidated financial statements included in "Item 1. Consolidated Financial Statements."

Cash Flow Information

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

	Six Months Ended June 30,
	2018			2017
	(In thousands)
Net cash provided by (used in)
Operating activities	$	379,802		$	157,714
Investing activities	(165,647		)	99,124
Financing activities	(202,705		)	(99,880		)

Net cash provided by operating activities consists of earnings adjusted for non-cash items, the effect of changes in working capital and acquisition-related contingent consideration payments (to the extent greater than the liability initially recognized at the time of acquisition). Non-cash adjustments include unrealized gains and losses on equity securities, stock-based compensation expense, amortization of intangibles, depreciation, gains from the sale of investments and businesses, bad debt expense and deferred income taxes.

2018

Adjustments to earnings primarily consist of $116.6 million of stock-based compensation expense, $40.1 million of amortization of intangibles, $38.1 million of depreciation and $20.9 million of bad debt expense, partially offset by $126.6 million of net unrealized gains on certain equity securities, $27.2 million of gains from the sale of investments and $11.3 million of deferred income taxes. The deferred income tax benefit primarily relates to the net operating loss created by the exercise and vesting of stock-based awards, partially offset by the deferred income tax provision on the net unrealized gains on certain equity securities. The decrease from changes in working capital primarily consists of an increase in accounts receivable of $60.2 million, an increase in other assets of $38.2 million, partially offset by an increase in deferred revenue of $45.6 million. The increase in accounts receivable is primarily due to revenue growth at ANGI, MTCH and Publishing. The increase in other assets is primarily related to increases in prepaid hosting services and capitalized mobile app store fees at MTCH and increases in capitalized sales commissions and prepaid marketing at ANGI. The increase in deferred revenue is due mainly to growth in subscription sales at MTCH, Vimeo and ANGI and an increase at Electus mainly due to the timing of cash received related to various production deals.

Net cash used in investing activities includes purchases (net of maturities and sales) of marketable debt securities of $114.4 million, cash used for acquisitions and investments of $48.7 million, and capital expenditures of $39.7 million, primarily related to investments in the development of capitalized software at ANGI and MTCH to support their products and services and computer hardware, partially offset by net proceeds from the sale of investments of $27.5 million and $10.4 million in net proceeds from the sale of Angie's List's campus located in Indianapolis.

Net cash used in financing activities includes $115.3 million and $21.4 million for withholding taxes paid on behalf of MTCH and ANGI employees, respectively, for stock-based awards that were net settled, $73.9 million for the repurchase of 1.7 million shares, on a settlement date basis, of MTCH common stock at an average price of $43.43 per share, $7.9 million for the repurchase of 0.1 million shares, on a settlement date basis, of IAC common stock at an average price of $150.81 per share, and $6.9 million in principal payments on ANGI debt, partially offset by $27.3 million in proceeds from the exercise of IAC stock options.

2017

Adjustments to earnings primarily consist of $72.9 million of stock-based compensation expense, $38.2 million of depreciation, $17.8 million of amortization of intangibles, $14.0 million of bad debt expense and $6.6 million of deferred income taxes, partially offset by $19.7 million of net gains from the sale of businesses and investments. The deferred income tax provision primarily relates to the exercise and vesting of stock-based awards. The decrease from changes in working capital

63

consists of a decrease in income taxes payable and receivable of $59.7 million, an increase in accounts receivable of $22.8 million, an increase in other assets of $18.5 million and a decrease in accounts payable and other current liabilities of $13.7 million, partially offset by an increase in deferred revenue of $15.2 million. The decrease in income taxes payable and receivable primarily relates to the exercise and vesting of stock-based awards. The increase in accounts receivable is primarily due to revenue growth at ANGI and MTCH. The increase in other assets is primarily related to an increase in prepaid marketing at ANGI and an increase in prepaid hosting services at MTCH. The decrease in accounts payable and other liabilities is due to an $11.1 million acquisition-related contingent consideration payment. The increase in deferred revenue is due mainly to growth in subscription sales at MTCH, ANGI and Vimeo, partially offset by decreases at Electus mainly due to the delivery of programming related to various production deals.

Net cash provided by investing activities includes net proceeds from the sale of businesses and investments of $119.7 million, which is primarily related to the proceeds from the sale of The Princeton Review, and proceeds from maturities and sales (net of purchases) of marketable debt securities of $74.4 million, partially offset by $49.2 million of cash used primarily for the MyBuilder and HomeStars acquisitions, and capital expenditures of $41.8 million, primarily related to the Company's purchase of a 50% ownership interest in an aircraft and investments in the development of capitalized software at MTCH and ANGI to support their products and services, as well as computer hardware.

Net cash used in financing activities includes $56.4 million for the repurchase of 0.8 million shares, on a settlement date basis, of IAC common stock at an average price of $69.24 per share, $49.9 million for withholding taxes paid on behalf of IAC employees for stock-based awards that are net settled, $31.6 million for the repurchases of IAC debt, $28.4 million for withholding taxes paid on behalf of MTCH employees for stock-based awards that are net settled, and $12.4 million for the purchase of noncontrolling interests, partially offset by $48.1 million and $39.4 million in proceeds from the exercise of IAC and MTCH stock options, respectively.

Liquidity and Capital Resources

The Company's principal sources of liquidity are its cash and cash equivalents and cash flows generated from operations. IAC's consolidated cash and cash equivalents at June 30, 2018 were $1.6 billion, of which $309.8 million was held by MTCH and $255.6 million was held by ANGI. The Company generated $379.8 million of operating cash flows for the six months ended June 30, 2018, of which $243.5 million was generated by MTCH and $73.6 million was generated by ANGI. Each of MTCH and ANGI is a separate and distinct legal entity with its own public shareholders and board of directors and has no obligation to provide the Company with funds. As a result, the Company cannot freely access the cash of MTCH and ANGI and their respective subsidiaries. In addition, agreements governing MTCH and ANGI 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 in the case of MTCH, its leverage ratio (as defined in the MTCH debt agreements) exceeds 5.0 to 1.0, and in the case of ANGI, its leverage ratio (as defined in the ANGI Term Loan) exceeds 4.0 to 1.0. There were no such limitations at June 30, 2018.

IAC has a $300 million revolving credit facility that expires on October 7, 2020. MTCH has a $500 million revolving credit facility that expires on October 7, 2020. Both credit facilities were undrawn as of June 30, 2018 and currently remain undrawn.

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 2018 capital expenditures are expected to be higher than 2017 by approximately 20%, driven, in part, by higher capital expenditures for ANGI related to the development of capitalized software to support its products and services, its new corporate headquarters in Denver and the expansion of office space in Indianapolis, partially offset by lower capital expenditures at Corporate.

During the six months ended June 30, 2018, IAC repurchased 0.1 million shares, on a trade date basis, of its common stock at an average price of $151.41 per share, or $14.7 million in aggregate. From July 1, 2018 through August 6, 2018, IAC repurchased an additional 0.4 million shares at an average price of $152.41 per share, or $68.2 million in aggregate. IAC has 8.0 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.

During the six months ended June 30, 2018, MTCH repurchased 1.9 million shares, on a trade date basis, of its common stock at an average price of $43.08 per share, or $79.8 million in aggregate. During July 2018, MTCH repurchased an additional 0.1 million shares at an average price of $39.21 per share, or $5.8 million in aggregate. MTCH has 4.0 million shares remaining in its share repurchase authorization.

64

The Company has granted stock options and stock settled stock appreciation rights denominated in the equity of certain non-publicly traded subsidiaries to employees and management of those subsidiaries. These equity awards are settled on a net basis, with the award holder entitled to receive a payment in IAC shares equal to the intrinsic value of the award at exercise less an amount equal to the required cash tax withholding payment. The number of IAC common shares that would be required to settle these vested and unvested interests, other than for MTCH, ANGI and their subsidiaries, at current estimated fair values, at August 6, 2018, is 0.1 million shares. Withholding taxes, which will be paid by the Company on behalf of the employees upon exercise, would have been $17.7 million at August 6, 2018, assuming a 50% withholding rate. The number of shares ultimately needed to settle these awards may vary significantly as a result of both movements in the Company's stock price and the determination of fair value of the relevant subsidiary that is different than the Company's estimate. The Company's RSUs and PSUs are awards in the form of phantom shares or units denominated in a hypothetical equivalent number of shares of IAC common stock. These equity awards are settled on a net basis. The number of IAC common shares that would be required to settle these awards at August 6, 2018, is 0.2 million shares. Withholding taxes, which will be paid by the Company on behalf of the employees upon vest, would have been $33.7 million at August 6, 2018, assuming a 50% withholding rate.

The Company's publicly traded subsidiaries have also granted equity awards denominated in the shares of those subsidiaries, all of which are currently being net settled and some of which may be settled using IAC shares.

MTCH currently settles all equity awards on a net basis. Assuming all MTCH equity awards outstanding on August 6, 2018 were net settled, MTCH would have issued 10.7 million common shares (of which 2.1 million is related to vested shares and 8.6 million is related to unvested shares) and would have remitted $412.9 million (of which $80.8 million is related to vested shares and $332.1 million is related to unvested shares) in cash for withholding taxes (assuming a 50% withholding rate). Certain MTCH stock options ("Tandem Awards") can be settled in MTCH or IAC common stock at the Company's election. Assuming all vested and unvested Tandem Awards outstanding on August 6, 2018 were exercised on that date and settled using IAC stock, 0.4 million IAC common shares would have been issued in settlement and MTCH would have issued 1.8 million shares, which is included in the amount above, to IAC as reimbursement.

In connection with the Combination, previously issued stock appreciation rights related to the common stock of HomeAdvisor (US) were converted into ANGI stock appreciation rights that are settleable on a net basis with ANGI remitting withholding taxes on behalf of the employee; most of these awards are not currently exercisable. At IAC's election, these awards are settled in Class A shares of ANGI or shares of IAC common stock. If settled in IAC common stock, ANGI reimburses IAC either in cash or through the issuance of Class A common shares to IAC. Assuming all converted stock appreciation rights outstanding on August 6, 2018 were settled using IAC stock, 1.8 million IAC common shares would have been issued in settlement and IAC would have been issued 16.7 million shares of ANGI Class A common stock and ANGI would have remitted $272.7 million in cash for withholding taxes (assuming a 50% withholding rate). ANGI is net settling substantially all other equity awards upon exercise or vesting. Assuming all other ANGI awards outstanding on August 6, 2018 were net settled, ANGI would have issued 1.2 million Class A common shares and would have remitted $19.9 million in cash for withholding taxes (assuming a 50% withholding rate).

As of June 30, 2018, IAC's economic and voting interest in MTCH is 81.2% and 97.6%, respectively, and in ANGI is 86.4% and 98.5%, respectively. As described above, certain MTCH and ANGI equity awards can be settled either in IAC common shares or the common shares of these subsidiaries at IAC's election. The Company currently expects to settle a sufficient number of awards in IAC shares to maintain an economic interest in both MTCH and ANGI of at least 80% and to otherwise take such other steps as necessary to maintain an economic interest in each of MTCH and ANGI of at least 80%.

The Company is not required to pay the one-time Transition Tax because of its net operating loss position. The Company does not expect to be a full U.S. federal cash income tax payer until 2021, which is in line with previous estimates. The Company expects the Tax Act to favorably impact its future liquidity, primarily as a result of a reduction in the U.S. corporate income tax rate from 35% to 21%, which will lower its effective tax rate and annual tax liability.

All of the Company’s international cash can be repatriated without significant tax consequences as it has been subjected to U.S. income taxes due to either the Transition Tax or tax on GILTI imposed by the Tax Act.  During the six months ended June 30, 2018, foreign cash of $326.0 million was repatriated to the U.S.

The Company believes its existing cash, cash equivalents, marketable securities and expected positive cash flows generated from operations will be sufficient to fund its normal operating requirements, including capital expenditures, debt service, the payment of withholding taxes paid 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 its products and services. The Company’s indebtedness could limit its ability to: (i) obtain additional financing to fund

65

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 business opportunities. 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 on terms favorable to the Company or at all.

66

CONTRACTUAL OBLIGATIONS AND COMMERCIAL COMMITMENTS

At June 30, 2018, there have been no material changes to the Company's contractual obligations, commercial commitments and off-balance sheet arrangements since the disclosure in our Annual Report on Form 10-K for the year ended December 31, 2017.

67

CRITICAL ACCOUNTING POLICIES AND 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 U.S. generally accepted accounting principles. These estimates, judgments and assumptions impact the reported amount of assets, liabilities, revenue and expenses and the related disclosure of contingent assets and liabilities. Actual results could differ from these estimates. Because of the size of the financial statement elements to which they relate, some of our accounting policies and estimates have a more significant impact on our consolidated financial statements than others. Presented below is an update to Part II, Item 7, the “Critical Accounting Policies and Estimates" following the adoption of ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, on January 1, 2018. There have been no other changes to our critical accounting policies and estimates since our Annual Report on Form 10-K for the year ended December 31, 2017. See "Note 1—The Company and Summary of Significant Accounting Policies" to the consolidated financial statements included in "Item 1. Consolidated Financial Statements" for the summary of significant accounting policies.

Investments in Debt and Equity Securities

Debt Securities

The Company invests in marketable debt securities with active secondary or resale markets to ensure portfolio liquidity to fund current operations or satisfy other cash requirements as needed. Marketable debt securities are adjusted to fair value each quarter, and the unrealized gains and losses, net of tax, are included in accumulated other comprehensive income (loss) as a separate component of shareholders' equity. The specific-identification method is used to determine the cost of debt securities sold and the amount of unrealized gains and losses reclassified out of accumulated other comprehensive income (loss) into earnings. The Company also invests in non-marketable debt securities as part of its investment strategy. We review our debt securities for impairment each reporting period. The Company recognizes an unrealized loss on debt securities in net earnings when the impairment is determined to be other-than-temporary. Factors we consider in making such determination include the duration, severity and reason for the decline in value and the potential recovery and our intent to sell the debt security. We also consider whether we will be required to sell the security before recovery of its amortized cost basis and whether the amortized cost basis cannot be recovered because of credit losses. If an impairment is considered to be other-than-temporary, the debt security will be written down to its fair value and the loss will be recognized within other income (expense), net.

Equity Securities

The Company invests in equity securities as part of its investment strategy. Our equity securities, other than those of our consolidated subsidiaries and those accounted for under the equity method, are accounted for at fair value or under the measurement alternative upon the adoption of ASU No. 2016-01 with changes recognized within other income (expense), net each reporting period. Under the measurement alternative, equity investments without readily determinable fair values are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Under the measurement alternative, the value of our equity securities without readily determinable fair values is generally determined based on a market approach as of the transaction date. We review impairment of our equity securities each reporting period when there are qualitative indicators that may indicate impairment. Once the qualitative indicators are identified and the fair value of the security is less than its carrying value, we will write down the security to its fair value and record the corresponding charge within other income (expense), net.

68

Item 3.    Quantitative and Qualitative Disclosures about Market Risk

At June 30, 2018, there have been no material changes to the Company's instruments or positions that are sensitive to market risk since the disclosure in our Annual Report on Form 10-K for the year ended December 31, 2017.

69

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 their 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 its 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 claims for damages 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) ARPU (as defined in "Item 2-Management's Discussion and Analysis of Financial Condition and Results of Operations-General-Key Terms" and which was referred to as ARPPU at the time the class action was filed) 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 was 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. 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. 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.

71

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 filed motions to dismiss the second amended consolidated complaint on December 15, 2017, the plaintiffs filed an opposition to the motions on January 29, 2018, and the defendants filed replies to the opposition on February 20, 2018. On March 8, 2018, the court issued an order transferring the case from Judge Lindsay to newly appointed Judge Scholer. On June 19, 2018, the court heard oral arguments on the motions, issued an oral ruling from the bench dismissing the second amended consolidated complaint without leave to amend, and indicated that a written opinion and order would be forthcoming. On July 10, 2018, pursuant to the court’s suggestion at oral argument, the defendants submitted a proposed order formalizing the court’s dismissal ruling.

Consumer Class Action Challenging Tinder’s Age-Tiered Pricing

On May 28, 2015, a putative state-wide class action was filed against Tinder in state court in California. See Allan Candelore v. Tinder, Inc., No. BC583162 (Superior Court of California, County of Los Angeles). The complaint principally alleged that Tinder violated California’s Unruh Civil Rights Act by offering and charging users age 30 and over a higher price than younger users for subscriptions to its premium Tinder Plus service. The complaint sought certification of a class of California Tinder Plus subscribers age 30 and over and damages in an unspecified amount. On September 21, 2015, Tinder filed a demurrer seeking dismissal of the complaint. On October 26, 2015, the court issued an opinion sustaining Tinder’s demurrer to the complaint without leave to amend, ruling that the age-based pricing differential for Tinder Plus subscriptions did not violate California law in essence because offering a discount to users under age 30 was neither invidious nor unreasonable in light of that age group’s generally more limited financial means. On December 29, 2015, in accordance with its ruling, the court entered judgment dismissing the action. On February 1, 2016, the plaintiff filed a notice of appeal from the judgment, and the parties thereafter briefed the appeal. On January 29, 2018, the California Court of Appeal (Second Appellate District, Division Three) issued an opinion reversing the judgment of dismissal, ruling that the lower court had erred in sustaining Tinder’s demurrer because the complaint, as pleaded, stated a cognizable claim for violation of the Unruh Act. Because we believe that the appellate court’s reasoning was flawed as a matter of law and runs afoul of binding California precedent, on March 12, 2018, Tinder filed a petition with the California Supreme Court seeking interlocutory review of the Court of Appeal’s decision.  On May 9, 2018, the California Supreme Court denied the petition. The case has been returned to the trial court for further proceedings. We and Match Group believe that the allegations in this lawsuit are without merit and will continue to defend vigorously against it.

Item 1A.    Risk Factors

Cautionary Statement Regarding Forward-Looking Information

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

Actual results could differ materially from those contained in these forward-looking statements for a variety of reasons, including, among others: (i) our continued ability to market, distribute and monetize our products and services through search engines, social media platforms and digital app stores, (ii) the failure or delay of the markets and industries in which our

72

businesses operate to migrate online, (iii) our continued ability to introduce new and enhanced products and services that resonate with consumers, (iv) our ability to market our various products and services in a successful and cost-effective manner, (v) our ability to compete effectively against current and future competitors, (vi) our ability to build, maintain and/or enhance our various brands, (vii) our ability to develop and monetize versions of our products and services for mobile and other digital devices, (viii) our continued ability to rely on third parties in connection with the distribution and use of our products and services, (ix) adverse economic events or trends, either generally and/or in any of the markets in which our businesses operate, (x) our continued ability to communicate with users and consumers via e-mail or an effective alternative means of communication, (xi) the migration of users from our higher monetizing dating products to our lower monetizing dating products, (xii) our ability to successfully offset increasing digital app store fees, (xiii) our ability to establish and maintain relationships with quality service professionals, (xiv) changes in our relationship with, or policies implemented by, Google, (xv) foreign exchange currency rate fluctuations, (xvi) our ability to protect our systems from cyberattacks and to protect personal and confidential user information, (xvii) the occurrence of data security breaches, fraud and/or additional regulation involving or impacting credit card payments, (xviii) the integrity, quality, scalability and redundancy of our systems, technology and infrastructure (and those of third parties with whom we do business), (xix) changes in key personnel, (xx) our ability to service our outstanding indebtedness, (xxi) dilution with respect to our investments in Match Group and ANGI Homeservices, (xxii) operational and financial risks relating to acquisitions and our continued ability to identify suitable acquisition candidates, (xxiii) our ability to successfully integrate Angie's List, (xxiv) our ability to expand successfully into international markets, (xxv) regulatory changes and (xxvi) our ability to adequately protect our intellectual property rights and not infringe the intellectual property rights of third parties. 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, 2017. Other unknown or unpredictable factors that could also adversely affect IAC's business, financial condition and operating results may arise from time to time. In light of these risks and uncertainties, the forward-looking statements discussed in this report may not prove to be accurate. Accordingly, you should not place undue reliance on these forward-looking statements, which only reflect the views of IAC management as of the date of this quarterly report. IAC does not undertake to update these forward-looking statements.

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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 composed of widely known consumer brands, such as Tinder, Match, PlentyOfFish and OkCupid, which are part of Match Group's online dating portfolio, and HomeAdvisor and Angie's List, which are operated by ANGI Homeservices, as well as Vimeo, Dotdash, Dictionary.com, The Daily Beast and Investopedia.

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

As of June 30, 2018, IAC’s economic and voting interest in Match Group were 81.2%, and 97.6%, respectively. All references to "Match Group" or "MTCH" in this report are to Match Group, Inc.

As of June 30, 2018, IAC’s economic and voting interest in ANGI Homeservices were 86.4%, and 98.5%, respectively. All reference to "ANGI Homeservices" or "ANGI" in this report are to ANGI Homeservices Inc.

Basis of Consolidation and Accounting for Investments

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

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.

Investments in equity securities, other than those of our consolidated subsidiaries and those accounted for under the equity method, are accounted for at fair value or under the measurement alternative upon the adoption of Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, on January 1, 2018, with changes recognized within other income (expense), net each reporting period. Under the measurement alternative, equity investments without readily determinable fair values are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Under the measurement alternative, the value of our equity securities without determinable fair values is generally determined based on a market approach as of the transaction date. An investment will be considered identical or similar if it has identical or similar rights to the equity investments held by the Company. The Company reviews impairment of our equity securities each reporting period when there are qualitative indicators that may indicate impairment. Once the qualitative indicators are identified and the fair value of the security is less than its carrying value, the Company will write down the security to its fair value and record the corresponding charge within other income (expense), net. See "Accounting Pronouncements adopted by the Company" below for further information.

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 included in the Company's Annual Report on Form 10-K for the year ended December 31, 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. Actual results could differ from these estimates.

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 values of marketable debt securities and equity securities without readily determinable fair values; 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; unrecognized tax benefits; the valuation allowance for deferred income tax assets; and the fair value of and forfeiture rates for stock-based awards, among others. The Company bases its estimates and judgments on historical experience, its forecasts and budgets and other factors that the Company considers relevant.

Certain Risks and Concentrations

A 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").

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. Google recently announced policy changes related to its Chrome browser, effective in September 2018, which could hurt the distribution of our desktop products through the Chrome Web Store and could impact revenue and profits of some of the businesses within our Applications segment. 

For the three and six months endedJune 30, 2018, revenue earned from Google was $204.9 million and $416.2 million, representing 19% and 20%, respectively, of the Company's consolidated revenue. For the three and six months ended June 30, 2017, revenue earned from Google was $174.6 million and $362.4 million, representing 23% and 24%, respectively, of the Company's consolidated revenue. This revenue is earned principally by the businesses comprising the Applications and Publishing segments. For the three and six months endedJune 30, 2018, revenue earned from Google represents 75% and 79%, respectively, of Applications revenue and 71% and 73%, respectively, of Publishing revenue. For both the three and six months ended June 30, 2017, revenue earned from Google represented 83% of Applications revenue and 70% of Publishing revenue. Accounts receivable related to revenue earned from Google totaled $73.4 million and $72.4 million at June 30, 2018 and December 31, 2017, respectively.

Recent Accounting Pronouncements

Accounting Pronouncements adopted by the Company

In May 2014, the FASB ASU No. 2014-09, Revenue from Contracts with Customers. ASU No. 2014-09 supersedes nearly all existing revenue recognition guidance under GAAP. The Company adopted ASU No. 2014-09 effective January 1, 2018 using the modified retrospective transition method for open contracts as of the date of initial application. The cumulative impact to the Company's retained earnings at January 1, 2018 was $40.2 million, of which $3.4 million was related to the Company's noncontrolling interest in ANGI; the adjustment to retained earnings was principally related to the Company’s ANGI Homeservices and Applications segments.

• Within ANGI, the effect of the adoption of ASU No. 2014-09 is that commissions paid to employees pursuant to certain sales incentive programs, which represent the incremental direct costs of obtaining a service professional contract, are now capitalized and amortized over the estimated life of a service professional (also referred to as the estimated customer relationship period). These costs were expensed as incurred prior to January 1, 2018. The cumulative effect of the adoption of ASU No. 2014-09 was the establishment of a current and non-current asset for capitalized sales commissions of $29.7 million and $4.2 million, respectively, and a related deferred tax liability of $8.0 million, resulting in a net increase to retained earnings of $25.9 million on January 1, 2018.

• Within Applications, the primary effect of the adoption of ASU No. 2014-09 is to accelerate the recognition of the portion of the revenue of certain desktop applications sold by SlimWare that qualifies as functional intellectual property ("functional IP") under ASU No. 2014-09. This revenue was previously deferred and recognized over the applicable subscription term. The cumulative effect of the adoption of ASU No. 2014-09 for SlimWare was a reduction in deferred revenue of $20.3 million and the establishment of a deferred tax liability of $4.9 million, resulting in a net increase to retained earnings of $15.5 million on January 1, 2018.

The adoption of ASU No. 2014-09 will not have a material effect on the Company’s results of operations for the year ending December 31, 2018. See "Note 2—Revenue Recognition" for additional information on the impact to the Company.

The Company's disaggregated revenue disclosures are presented in "Note 10—Segment information."

The following tables present the impact of the adoption of ASU No. 2014-09 by segment under Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers, as reported, and ASC 605, Revenue Recognition, for the three and six months ended June 30, 2018.

In January 2016, the FASB issued ASU No. 2016-01, which updates certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Under ASU No. 2016-01, equity securities, other than those of our consolidated subsidiaries and those accounted for under the equity method, will be measured at fair value with changes in fair value recognized in the statement of operations each reporting period. ASU No. 2016-01 is effective for reporting periods beginning after December 15, 2017. There was no cumulative impact to the Company's consolidated financial statements upon adoption of ASU No. 2016-01 on January 1, 2018. The adoption of ASU No. 2016-01 increases the volatility of the Company's other income (expense), net as a result of the remeasurement of these instruments. For the three and six months endedJune 30, 2018, other income, net includes net unrealized gains related to certain equity securities that were adjusted to fair value in accordance with ASU No. 2016-01 of $126.4 million and $126.6 million, respectively. See "Note 6—Fair Value Measurements and Financial Instruments" for additional information.

In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash, which requires companies to explain the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. Therefore, amounts generally described as restricted cash or restricted cash equivalents are combined with unrestricted cash and cash equivalents when reconciling the beginning and end of period balances on the statement of cash flows. ASU No. 2016-18 also requires companies to disclose the nature of their restricted cash and restricted cash equivalents balances. Additionally, when cash, cash equivalents, restricted cash, and restricted cash equivalents are presented within different captions on the balance sheet, a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet is required. ASU No. 2016-18 is effective for reporting periods beginning after December 15, 2017. The Company's adoption of ASU No. 2016-18 effective January 1, 2018, on a retrospective basis, did not have a material effect on its consolidated financial statements.

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balance sheet to the total amounts shown in the consolidated statement of cash flows:

	June 30, 2018		December 31, 2017		June 30, 2017		December 31, 2016
	(In thousands)
Cash and cash equivalents	$	1,644,829	$	1,630,809	$	1,522,300	$	1,329,187
Restricted cash included in other current assets	347		2,873		331		20,464
Restricted cash included in other assets	—		—		—		10,548
Total cash, cash equivalents and restricted cash as shown on the consolidated statement of cash flows	$	1,645,176	$	1,633,682	$	1,522,631	$	1,360,199

Restricted cash at December 31, 2017 primarily supports a letter of credit to a supplier, which was released to the Company in the second quarter of 2018.

Restricted cash at December 31, 2016 primarily included funds held in escrow for the redemption and repurchase of IAC Senior Notes and the MyHammer tender offer. In the first quarter of 2017, the Senior Notes were redeemed and repurchased and the funds held in escrow for the MyHammer tender offer were returned to the Company.

In June 2018, the FASB issued ASU No. 2018-07, Improvements to Nonemployee Share-Based Payment Accounting, which largely aligns the measurement and classification guidance for share-based payments granted to non-employees with the guidance for share-based payments granted to employees. The new guidance supersedes Subtopic 505-50, Equity - Equity-Based payments to Nonemployees. ASU No. 2018-07 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The Company adopted ASU No. 2018-07 effective April 1, 2018 and its adoption did not have a material effect on its consolidated financial statements. The effect of the adoption of ASU No. 2018-07 will be to minimize the volatility of expense related to stock-based awards to non-employees in the future.

Accounting Pronouncement not yet adopted by the Company

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. In July 2018, the FASB issued ASU No. 2018-11, which provides the option of an additional transition method that allows entities to initially apply the new lease guidance at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company expects to implement the transition method option provided by ASU No. 2018-11. The Company will adopt the new lease guidance effective January 1, 2019.

The Company is not a lessor, has no capitalized leases and does not expect to enter into any capitalized leases prior to the adoption of ASU No. 2016-02. Accordingly, the Company does not expect the amount or classification of rent expense in its statement of operations to be affected by the adoption of ASU No. 2016-02. The primary effect of the adoption of ASU No. 2016-02 will be the recognition of a right of use asset and related liability to reflect the Company's rights and obligations under its operating leases. The Company will also be required to provide the additional disclosures stipulated in ASU No. 2016-02.

The adoption of ASU No. 2016-02 will not have an impact on the leverage calculation set forth in any of the agreements governing the outstanding debt of the Company or its MTCH and ANGI subsidiaries, or our credit agreement or the credit agreement of MTCH because, in each circumstance, the leverage calculations are not affected by the liability that will be recorded upon adoption of the new standard.

While the Company's evaluation of the impact of the adoption of ASU No. 2016-02 on its consolidated financial statements continues, outlined below is a summary of the status of the Company's progress:

• the Company has selected a software package to assist in the determination of the right of use asset and related liability as of January 1, 2019 and to provide the required information following the adoption;

• the Company has prepared summaries of its leases for input into the software package;

• the Company is assessing the other inputs required in connection with the adoption of ASU No. 2016-02; and

• the Company is developing its accounting policy, procedures and controls related to the new standard.

The Company does not expect to have a preliminary estimate of the right of use asset and related liability as of the adoption date until the fourth quarter of 2018.

REVENUE RECOGNITION

6 Months Ended

Jun. 30, 2018

Revenue from Contract with Customer [Abstract]

REVENUE RECOGNITION

REVENUE RECOGNITION

General Revenue Recognition

The Company accounts for a contract when it has approval and commitment from all parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue is recognized when control of the promised services or goods is transferred to our customers, and in an amount that reflects the consideration the Company is contractually due in exchange for those services or goods.

Match Group

Match Group’s revenue is primarily derived directly from users in the form of recurring subscriptions. Subscription revenue is presented net of credits and credit card chargebacks. Subscribers pay in advance, primarily by credit card or through mobile app stores, and, subject to certain conditions identified in our terms and conditions, generally all purchases are final and nonrefundable. Revenue is initially deferred and is recognized using the straight-line method over the term of the applicable subscription period, which primarily range from one to six months. Revenue is also earned from online advertising, the purchase of à la carte features and offline events. Online advertising revenue is recognized when an advertisement is displayed. Revenue from the purchase of à la carte features is recognized based on usage. Revenue associated with offline events is recognized when each event occurs.

ANGI Homeservices

ANGI revenue is primarily derived from (i) consumer connection revenue, which comprises fees paid by service professionals for consumer matches (regardless of whether the professional ultimately provides the requested service), and (ii) membership subscription fees paid by service professionals. Consumer connection revenue varies based upon several factors, including the service requested, type of match and geographic location of service. The Company’s consumer connection revenue is generated and recognized when an in-network service professional is delivered a consumer match. Membership subscription revenue from service professionals is initially deferred and is recognized using the straight-line method over the applicable subscription period, which is typically one year. Consumer connection revenue is generally billed one week following a consumer match; with payment due upon receipt of invoice.

ANGI revenue is also derived from Angie's List (i) sales of time-based website, mobile and call center advertising to service professionals and (ii) membership subscription fees from consumers. Angie's List service professionals generally pay for advertisements in advance on a monthly or annual basis at the option of the service professional, with the average advertising contract term being approximately one year. Angie's List website, mobile and call center advertising revenue is recognized ratably over the contract term. Revenue from the sale of advertising in the Angie’s List Magazine is recognized in the period in which the publication is distributed. Angie's List prepaid consumer membership subscription fees are recognized as revenue using the straight-line method over the term of the applicable subscription period, which is typically one year.

Video

Revenue of businesses in this segment is generated primarily through subscriptions, media production and distribution, and advertising. Subscription fee revenue is recognized over the terms of the applicable subscription period, which are one month or one year, production revenue is recognized when control is transferred to the customer to broadcast or exhibit, and advertising revenue is recognized when an advertisement is displayed or over the advertising period.

Applications

Applications' revenue largely consists of advertising revenue generated principally through the display of paid listings in response to search queries. The substantial majority of the paid listings displayed by our Applications businesses are supplied to us by Google pursuant to our services agreement with Google.

Pursuant to this agreement, those of our Applications businesses that provide search services transmit search queries to Google, which in turn transmits a set of relevant and responsive paid listings back to these businesses for display in search results. This ad-serving process occurs independently of, but concurrently with, the generation of algorithmic search results for the same search queries. Google paid listings are displayed separately from algorithmic search results and are identified as sponsored listings on search results pages. Paid listings are priced on a price per click basis and when a user submits a search query through one of our Applications businesses and then clicks on a Google paid listing displayed in response to the query, Google bills the advertiser that purchased the paid listing directly and shares a portion of the fee charged to the advertiser with us. The Company recognizes paid listing revenue from Google when it delivers the user's click. In cases where the user’s click is generated due to the efforts of a third-party distributor, we recognize the amount due from Google as revenue and record a revenue share or other payment obligation to the third-party distributor as traffic acquisition costs.

To a significantly lesser extent, Applications' revenue also consists of fees related to subscription downloadable desktop and mobile applications as well as display advertisements. Fees related to subscription downloadable desktop and paid mobile applications are generally recognized at the time of the sale when the software license is delivered. To the extent updates or maintenance is required or expected, revenue is recognized over the term of the applicable subscription period, which is primarily one or two years. Fees related to display advertisements are recognized when an advertisement is displayed.

Publishing

Publishing's revenue consists principally of advertising revenue, which is generated primarily through the display of paid listings in response to search queries and display advertisements (sold directly and through programmatic ad sales). The majority of the paid listings that our Publishing businesses display are supplied to us by Google in the manner, and pursuant to the services agreement with Google, described above under "Applications."

Transaction Price

The objective of determining the transaction price is to estimate the amount of consideration the Company is due in exchange for its services or goods, including amounts that are variable. The Company determines the total transaction price, including an estimate of any variable consideration, at contract inception and reassesses this estimate each reporting period.

The Company excludes from the measurement of transaction price all taxes assessed by governmental authorities that are both (i) imposed on and concurrent with a specific revenue-producing transaction and (ii) collected from customers. Accordingly, such tax amounts are not included as a component of revenue or cost of revenue.

For contracts that have an original duration of one year or less, the Company uses the practical expedient available under ASU No. 2014-09 applicable to such contracts and does not consider the time value of money.

Accounts Receivables, net of allowance for doubtful accounts and revenue reserves

Accounts receivable include amounts billed and currently due from customers. The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivables that will not be collected. The allowance for doubtful accounts is based upon a number of factors, including the length of time accounts receivable are past due, the Company’s previous loss history and the specific customer’s ability to pay its obligation. The time between the Company issuance of an invoice and payments due date is not significant; customer payments that are not collected in advance of the transfer of promised services or goods are generally due no later than 30 days from invoice date. The Company also maintains allowances to reserve for potential credits issued to consumers or other revenue adjustments. The amounts of these reserves are based primarily upon historical experience.

Deferred Revenue

Deferred revenue consists of advance payments that are received or due in advance of the Company's performance. The Company’s liabilities are reported on a contract by contract basis at the end of each reporting period. The Company generally classifies deferred revenue as current when the term of the applicable subscription period or expected completion of our performance obligation is one year or less. The deferred revenue balance as of January 1, 2018 is $332.2 million. During the three months endedJune 30, 2018, the Company recognized $224.0 million of revenue that was included in the deferred revenue balance as of April 1, 2018. During the six months endedJune 30, 2018, the Company recognized $278.8 million of revenue that was included in the deferred revenue balance as of January 1, 2018. The current and non-current deferred revenue balances at June 30, 2018 are $375.1 million and $2.0 million, respectively. Non-current deferred revenue is included in “Other long-term liabilities” in the accompanying consolidated balance sheet.

Arrangements with Multiple Performance Obligations

The Company’s contracts with customers may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on the prices charged to customers, which are directly observable or based on an estimate if not directly observable. For our multiple performance obligation arrangements that include functional intellectual property ("IP"), which comprise the downloadable apps and software of the Applications segment, the Company uses a residual approach to determine standalone selling prices for the functional IP.

Assets Recognized from the Costs to Obtain a Contract with a Customer

The Company has determined that certain costs, primarily commissions paid to employees pursuant to certain sales incentive programs and mobile app store fees, meet the requirements to be capitalized as a cost of obtaining a contract. Commissions paid to employees pursuant to certain sales incentive programs are amortized over the estimated customer relationship period. The Company calculates the estimated customer relationship period as the average customer life, which is based on historical data. When customer renewals are expected and the renewal commission is not commensurate with the initial commission, the average customer life includes renewal periods. For sales incentive programs where the customer relationship period is one year or less, the Company has elected the practical expedient to expense the costs as incurred. The Company generally capitalizes and amortizes mobile app store fees over the term of the applicable subscription.

During the three and six months endedJune 30, 2018, the Company recognized expense of $84.7 million and $159.8 million, respectively, related to the amortization of these costs. The contract asset balance at June 30, 2018 is $72.8 million.

Performance Obligations

As permitted under the practical expedient available under ASU No. 2014-09, the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts with variable consideration that is allocated entirely to unsatisfied performance obligations or to a wholly unsatisfied promise accounted for under the series guidance, and (iii) contracts for which the Company recognizes revenue at the amount which we have the right to invoice for services performed.

INCOME TAXES

6 Months Ended

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 unrecognized tax benefits is recognized in the interim period in which the change occurs.

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

For the three months ended June 30, 2018, the Company recorded an income tax provision of $31.4 million, which represents an effective income tax rate of 10%. The effective tax rate is lower than the statutory rate of 21% due primarily to excess tax benefits generated by the exercise and vesting of stock-based awards. For the six months endedJune 30, 2018, the Company recorded an income tax provision of $2.4 million, which represents an effective income tax rate of 1%. The effective tax rate is lower than the statutory rate of 21% due primarily to excess tax benefits generated by the exercise and vesting of stock-based awards. For the three and six months ended June 30, 2017, the Company recorded an income tax benefit, despite pre-tax income, of $19.4 million and $43.3 million, respectively, due primarily to excess tax benefits generated by the exercise and vesting of stock-based awards.

On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act subjected to U.S. taxation certain previously deferred earnings of foreign subsidiaries as of December 31, 2017 (“Transition Tax”) and implemented a number of changes that took effect on January 1, 2018, including but not limited to, a reduction of the U.S. federal corporate tax rate from 35% to 21% and a new minimum tax on global intangible low-taxed income (“GILTI”) earned by foreign subsidiaries. The Company was able to make a reasonable estimate of the Transition Tax and recorded a provisional tax expense in the fourth quarter of 2017. The Company was also able to make a reasonable estimate of the impact of GILTI on the expected annual effective income tax rate and recorded a tax expense for the three and six months ended June 30, 2018. Any adjustment of the Company’s provisional tax expense will be reflected as a change in estimate in its results in the period in which the change in estimate is made in accordance with Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, which is also included in the FASB issued ASU No. 2018-05, Income Taxes (Topic 740), Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118, whichwasissued and adopted by the Company in March 2018. The Company is continuing to gather additional information to more precisely compute the amount of the Transition Tax and expects to finalize its calculation prior to the filing of its U.S. federal tax return, which is due on October 15, 2018. The additional information includes, but is not limited to, the allocation and sourcing of income and deductions in 2017 for purposes of calculating the utilization of foreign tax credits. In addition, our estimates may also be impacted and adjusted as the law is clarified and additional guidance is issued at the federal and state levels. No adjustment was made in the three and six months ended June 30, 2018 to the Company’s previously recorded provisional tax expense, including for the impact of the issuance of Treasury Notices 2018-26 and 2018-28 as we continue to assess their impact, which we believe is immaterial.

The Company recognizes interest and, if applicable, penalties related to unrecognized tax benefits in the income tax provision. Accruals for interest and penalties are not material.

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 2016. The statute of limitations for the years 2010 through 2012 has been extended to June 30, 2019, and the statute of limitations for the years 2013 and 2014 has been extended to March 31, 2019. Various other jurisdictions are open to examination for tax years beginning with 2009. Income taxes payable include unrecognized tax benefits considered sufficient to pay assessments that may result from examination of prior year tax returns. We consider many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes. Although management currently believes changes in unrecognized tax benefits from period to period and differences between amounts paid, if any, upon resolution of issues raised in audits and amounts previously provided 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.

At June 30, 2018 and December 31, 2017, unrecognized tax benefits, including interest and penalties, are $40.5 million and $39.7 million, respectively. If unrecognized tax benefits at June 30, 2018 are subsequently recognized, $37.6 million, net of related deferred tax assets and interest, would reduce income tax expense. The comparable amount as of December 31, 2017 was $37.2 million. The Company believes that it is reasonably possible that its unrecognized tax benefits could decrease by $12.7 million by June 30, 2019, due to expirations of statutes of limitations; $12.4 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 June 30, 2018, the Company has a gross deferred tax asset of $125.0 million that the Company expects to fully utilize on a more likely than not basis.

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 market prices for identical assets and liabilities in active markets.

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

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

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

Contingent Consideration Arrangements

As of June 30, 2018, there are three contingent consideration arrangements related to business acquisitions. Two of the contingent consideration arrangements have limits as to the maximum amount that can be paid. The maximum contingent payments related to these arrangements is $32.0 million and the gross fair value of these arrangements, before the unamortized discount, at June 30, 2018 is $2.0 million. No payment is expected for the one contingent consideration arrangement without a limit on the maximum earnout.

The contingent consideration arrangements are based upon earnings performance and/or operating metrics. The Company generally determines the fair value of the contingent consideration arrangements by using probability-weighted analyses to determine the amounts of the gross liability, and, because the arrangements were 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 June 30, 2018 and December 31, 2017 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 June 30, 2018 and December 31, 2017 includes a current portion of $1.9 million and $0.6 million, respectively, and non-current portion of $2.0 million at December 31, 2017, which are included in “Accrued expenses and other current liabilities” and “Other long-term liabilities,” respectively, in the accompanying consolidated balance sheet. At June 30, 2018, there is no non-current portion of the contingent consideration arrangement liability.

Equity securities without readily determinable fair values

At June 30, 2018 and December 31, 2017, the carrying values of the Company's investments in equity securities without readily determinable fair values totaled $216.2 million and $63.4 million, respectively, and are included in "Long-term investments" in the accompanying consolidated balance sheet. Following the adoption of the measurement alternative under ASU No. 2016-01 on January 1, 2018, the Company's equity securities without readily determinable fair values are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. All gains and losses on equity securities without readily determinable fair values, realized and unrealized, are recognized in "other income, net" in the accompanying consolidated statement of operations.

The following table presents a summary of realized and unrealized gains and losses recorded in other income (expense), net, as adjustments to the carrying value of equity securities without readily determinable fair values held as of June 30, 2018. The gross unrealized gains relate to the Company's remaining investments in an investee following the sale of a portion of the Company's investment during the second quarter of 2018.

Total	$	126,390		$	126,198

Realized and unrealized gains and losses for the Company's marketable equity security and investments without a readily determinable fair value for the three and six months ended June 30, 2018 are as follows:

	Three Months Ended June 30, 2018		Six Months Ended June 30, 2018

Unrealized gains, net, on equity securities held	126,414		126,559
Total gains recognized, net, in other income, net	$	153,689	$	153,731

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 method investments, are adjusted to fair value only when an impairment charge is recognized. The Company's financial assets, comprising equity securities without readily determinable fair values, are adjusted to fair value when observable price changes are identified or an impairment charge is recognized. Such fair value measurements are based predominantly on Level 3 inputs.

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:

MTCH Senior Notes

The 6.375% MTCH Senior Notes were issued on June 1, 2016. The proceeds of $400 million were used to prepay a portion of indebtedness outstanding under the MTCH 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.

On December 4, 2017, MTCH issued $450 million aggregate principal amount of its 5.00% Senior Notes. The proceeds from these notes, along with cash on hand, were used to redeem the $445.2 million outstanding balance of the 6.75% MTCH Senior Notes, which were due on December 15, 2022, and pay the related call premium. At any time prior to December 15, 2022, the 5.00% MTCH 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 6.375% and 5.00% MTCH Senior Notes (i) contain covenants that would limit MTCH's ability to pay dividends or to make distributions and repurchase or redeem MTCH stock in the event a default has occurred or MTCH's leverage ratio (as defined in the indentures) exceeds 5.0 to 1.0 and (ii) are ranked equally with each other. At June 30, 2018, there were no limitations pursuant thereto. There are additional covenants that limit MTCH's ability and the ability of its subsidiaries to, among other things, (i) incur indebtedness, make investments, or sell assets in the event MTCH is not in compliance with certain ratios set forth in the indentures, and (ii) incur liens, enter into agreements restricting MTCH subsidiaries' ability to pay dividends, enter into transactions with affiliates and consolidate, merge or sell substantially all of their assets.

MTCH Term Loan and MTCH Credit Facility

At both June 30, 2018 and December 31, 2017, the outstanding balance on the MTCH Term Loan was $425 million and the loan bears interest at LIBOR plus 2.50%. The interest rate of the MTCH Term Loan was 4.59% and 3.85% at June 30, 2018 and December 31, 2017, respectively. The MTCH Term Loan provides for 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 credit agreement. Interest payments are due at least quarterly through the term of the loan.

MTCH has a $500 million revolving credit facility (the "MTCH Credit Facility") that expires on October 7, 2020. At June 30, 2018 and December 31, 2017, there were no outstanding borrowings under the MTCH Credit Facility. The annual commitment fee on undrawn funds based on the current leverage ratio is 30 basis points. Borrowings under the MTCH Credit Facility bear interest, at MTCH'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 MTCH's consolidated net leverage ratio. The terms of the MTCH Credit Facility require MTCH 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 MTCH Credit Facility and the MTCH Term Loan that limit the ability of MTCH and its subsidiaries to, among other things, incur indebtedness, pay dividends or make distributions. While the MTCH Term Loan remains outstanding, these same covenants under its credit agreement are generally more restrictive than the covenants that are applicable to the MTCH Credit Facility. Obligations under the MTCH Credit Facility and MTCH Term Loan are unconditionally guaranteed by certain MTCH wholly-owned domestic subsidiaries, and are also secured by the stock of certain MTCH domestic and foreign subsidiaries. The MTCH Term Loan and outstanding borrowings, if any, under the MTCH Credit Facility rank equally with each other, and have priority over the 6.375% and 5.00% MTCH Senior Notes to the extent of the value of the assets securing the borrowings under the MTCH credit agreement.

ANGI Term Loan:

At June 30, 2018 and December 31, 2017, the outstanding balance on the ANGI Term Loan was $268.1 million and $275.0 million respectively. The ANGI Term Loan bears interest at LIBOR plus 2.00%, which is subject to change in future periods based on ANGI's consolidated net leverage ratio, and was 4.36% and 3.38% at June 30, 2018 and December 31, 2017, respectively. Interest payments are due at least quarterly through the term of the loan and quarterly principal payments of 1.25% of the original principal amount in the first three years, 2.5% in the fourth year and 3.75% in the fifth year are required.

The terms of the ANGI Term Loan require ANGI to maintain a consolidated net leverage ratio of not more than 4.5 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 credit agreement). There are additional covenants under the ANGI Term Loan that limit the ability of ANGI and its subsidiaries to, among other things, incur indebtedness, pay dividends or make distributions. The ANGI Term Loan is guaranteed by ANGI's wholly-owned material domestic subsidiaries and is secured by substantially all assets of ANGI and the guarantors, subject to certain exceptions.

IAC Exchangeable Notes:

On October 2, 2017, IAC FinanceCo, Inc., a direct, wholly-owned subsidiary of the Company, issued $517.5 million aggregate principal amount of its 0.875% Exchangeable Senior Notes (the “Exchangeable Notes”). The Exchangeable Notes are guaranteed by the Company. Each $1,000 of principal of the Exchangeable Notes is exchangeable for 6.5713 shares of the Company's common stock, which is equivalent to an exchange price of approximately $152.18 per share, subject to adjustment upon the occurrence of specified events. Upon exchange, the Company has the right to settle the principal amount of Exchangeable Notes with any of the three following alternatives: (1) shares of our common stock, (2) cash or (3) a combination of cash and shares of our common stock.

The Exchangeable Notes are exchangeable at any time prior to the close of business on the business day immediately preceding July 1, 2022 only under the following circumstances: (1) during any calendar quarter (and only during such calendar quarter), if the last reported sale price of our common stock for at least 20 trading days during the period of 30 consecutive trading days during the immediately preceding calendar quarter is greater than or equal to 130% of the exchange price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the exchange rate on each such trading day; (3) if the issuer calls the notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events as further described under the indenture governing the Exchangeable Notes. On or after July 1, 2022 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may exchange all or any portion of their Exchangeable Notes regardless of the foregoing conditions.

A portion of the net proceeds from the sale of the Exchangeable Notes of $499.5 million, after deducting fees and expenses, was used to pay the net premium of $50.7 million on the Exchangeable Note Hedge and Warrant (defined below).

We separately account for the debt and the equity components of the Exchangeable Notes. Accordingly, the Company recorded a debt discount and corresponding increase to additional paid-in capital of $70.4 million, which is the fair value attributed to the exchange feature or equity component of the debt, on the date of issuance. The Company is amortizing the debt discount utilizing the effective interest method over the life of the Exchangeable Notes which increases the effective interest rate from its coupon rate of 0.875% to 3.88%.

In connection with the debt offering, the Company purchased call options allowing the Company to purchase initially (subject to adjustment upon the occurrence of specified events) the entire 3.4 million shares that would be issuable upon the exchange of the Exchangeable Notes at approximately $152.18 per share (the "Exchangeable Note Hedge"), and sold warrants allowing the holder to purchase initially (subject to adjustment upon the occurrence of specified events) 3.4 million shares at $229.70 per share (the "Warrant"). The Exchangeable Note Hedge is 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 would 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 exceeds the applicable strike price of the Warrants.

As of June 30, 2018, the if-converted value of the Exchangeable Notes exceeds its principal amount by $1.1 million based on the Company's stock price on June 30, 2018.

For the three and six months endedJune 30, 2018, the Company incurred interest expense of $5.3 million and $10.5 million, which includes amortization of original issue discount of $3.3 million and $6.5 million, and debt issuance costs of $0.8 million and $1.7 million, respectively. As of June 30, 2018, the unamortized discount is $60.7 million resulting in a net carrying value of the liability component of $456.8 million.

IAC Senior Notes

The 4.75% Senior Notes were issued by IAC on December 21, 2012. These Notes are unconditionally guaranteed by certain of our wholly-owned domestic subsidiaries, which are designated as guarantor subsidiaries. See "Note 13—Guarantor and Non-Guarantor Financial Information" for financial information relating to guarantor and non-guarantor subsidiaries. The 4.75% Senior 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.

IAC Credit Facility

IAC has a $300 million revolving credit facility (the "IAC Credit Facility") that expires October 7, 2020. At June 30, 2018 and December 31, 2017, there were no outstanding borrowings under the IAC Credit Facility. The annual commitment fee on undrawn funds is 25 basis points, and is based on the leverage ratio (as defined in the agreement) 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 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 substantially the same domestic subsidiaries that guarantee the 4.75% Senior Notes and are also secured by the stock of certain of our domestic and foreign subsidiaries. The 4.75% Senior Notes are subordinate to the outstanding borrowings under the IAC Credit Facility to the extent of the value of the assets securing such borrowings.

________________________

^(a)  For the three and six months endedJune 30, 2018, it is more dilutive for IAC to settle certain MTCH and ANGI equity awards.  For the three and six months ended June 30, 2017, it is more dilutive for MTCH to settle certain MTCH equity awards.  The impact from ANGI’s dilutive securities is not applicable for periods prior to the Combination.

^(b)  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, warrants and subsidiary denominated equity, exchange of the Company's Exchangeable Notes and vesting of restricted stock units ("RSUs"). For the three and six months endedJune 30, 2018, 3.4 million and 6.9 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive. For the three and six months ended June 30, 2017, less than 0.1 million and 0.5 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive.

^(c)  Market-based awards and performance-based stock units (“PSUs”) are considered contingently issuable shares. Shares issuable upon exercise or vesting of market-based awards and PSUs are included in the denominator for earnings per share if (i) the applicable market or performance condition(s) has been met and (ii) the inclusion of the market-based awards and PSUs is dilutive for the respective reporting periods. For both the three and six months endedJune 30, 2018, 0.2 million shares underlying market-based awards and PSUs were excluded from the calculation of diluted earnings per share because the market or performance conditions had not been met. For both the three and six months ended June 30, 2017, 0.4 million shares underlying market-based awards and PSUs were excluded from the calculation of diluted earnings per share because the market or performance conditions had not been met.

^(d)  It is the Company's intention to settle the Exchangeable Notes through a combination of cash, equal to the face amount of the notes, and shares; therefore, the Exchangeable Notes are only dilutive for periods during which the average price of IAC common stock exceeds the approximate $152.18 per share exchange price per $1,000 principal amount of the Exchangeable Notes.

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.

________________________

^(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 businesses, and this measure is one of the primary metrics on 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. 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 3—Income Taxes" for additional information related to income tax contingencies.

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

6 Months Ended

Jun. 30, 2018

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Nature of Operations

IAC is a leading media and Internet company composed of widely known consumer brands, such as Tinder, Match, PlentyOfFish and OkCupid, which are part of Match Group's online dating portfolio, and HomeAdvisor and Angie's List, which are operated by ANGI Homeservices, as well as Vimeo, Dotdash, Dictionary.com, The Daily Beast and Investopedia.

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

Basis of Presentation

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

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.

Investments in equity securities, other than those of our consolidated subsidiaries and those accounted for under the equity method, are accounted for at fair value or under the measurement alternative upon the adoption of Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, on January 1, 2018, with changes recognized within other income (expense), net each reporting period. Under the measurement alternative, equity investments without readily determinable fair values are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Under the measurement alternative, the value of our equity securities without determinable fair values is generally determined based on a market approach as of the transaction date. An investment will be considered identical or similar if it has identical or similar rights to the equity investments held by the Company. The Company reviews impairment of our equity securities each reporting period when there are qualitative indicators that may indicate impairment. Once the qualitative indicators are identified and the fair value of the security is less than its carrying value, the Company will write down the security to its fair value and record the corresponding charge within other income (expense), net. See "Accounting Pronouncements adopted by the Company" below for further information.

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 included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017.

Accounting for Investments

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

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.

Investments in equity securities, other than those of our consolidated subsidiaries and those accounted for under the equity method, are accounted for at fair value or under the measurement alternative upon the adoption of Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, on January 1, 2018, with changes recognized within other income (expense), net each reporting period. Under the measurement alternative, equity investments without readily determinable fair values are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Under the measurement alternative, the value of our equity securities without determinable fair values is generally determined based on a market approach as of the transaction date. An investment will be considered identical or similar if it has identical or similar rights to the equity investments held by the Company. The Company reviews impairment of our equity securities each reporting period when there are qualitative indicators that may indicate impairment. Once the qualitative indicators are identified and the fair value of the security is less than its carrying value, the Company will write down the security to its fair value and record the corresponding charge within other income (expense), net.

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 included in the Company's Annual Report on Form 10-K for the year ended December 31, 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. Actual results could differ from these estimates.

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 values of marketable debt securities and equity securities without readily determinable fair values; 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; unrecognized tax benefits; the valuation allowance for deferred income tax assets; and the fair value of and forfeiture rates for stock-based awards, among others. The Company bases its estimates and judgments on historical experience, its forecasts and budgets and other factors that the Company considers relevant.

Certain Risks and Concentrations

A 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").

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. Google recently announced policy changes related to its Chrome browser, effective in September 2018, which could hurt the distribution of our desktop products through the Chrome Web Store and could impact revenue and profits of some of the businesses within our Applications segment.

Recent Accounting Pronouncements

Accounting Pronouncements adopted by the Company

In May 2014, the FASB ASU No. 2014-09, Revenue from Contracts with Customers. ASU No. 2014-09 supersedes nearly all existing revenue recognition guidance under GAAP. The Company adopted ASU No. 2014-09 effective January 1, 2018 using the modified retrospective transition method for open contracts as of the date of initial application. The cumulative impact to the Company's retained earnings at January 1, 2018 was $40.2 million, of which $3.4 million was related to the Company's noncontrolling interest in ANGI; the adjustment to retained earnings was principally related to the Company’s ANGI Homeservices and Applications segments.

• Within ANGI, the effect of the adoption of ASU No. 2014-09 is that commissions paid to employees pursuant to certain sales incentive programs, which represent the incremental direct costs of obtaining a service professional contract, are now capitalized and amortized over the estimated life of a service professional (also referred to as the estimated customer relationship period). These costs were expensed as incurred prior to January 1, 2018. The cumulative effect of the adoption of ASU No. 2014-09 was the establishment of a current and non-current asset for capitalized sales commissions of $29.7 million and $4.2 million, respectively, and a related deferred tax liability of $8.0 million, resulting in a net increase to retained earnings of $25.9 million on January 1, 2018.

• Within Applications, the primary effect of the adoption of ASU No. 2014-09 is to accelerate the recognition of the portion of the revenue of certain desktop applications sold by SlimWare that qualifies as functional intellectual property ("functional IP") under ASU No. 2014-09. This revenue was previously deferred and recognized over the applicable subscription term. The cumulative effect of the adoption of ASU No. 2014-09 for SlimWare was a reduction in deferred revenue of $20.3 million and the establishment of a deferred tax liability of $4.9 million, resulting in a net increase to retained earnings of $15.5 million on January 1, 2018.

The adoption of ASU No. 2014-09 will not have a material effect on the Company’s results of operations for the year ending December 31, 2018. See "Note 2—Revenue Recognition" for additional information on the impact to the Company.

The Company's disaggregated revenue disclosures are presented in "Note 10—Segment information."

The following tables present the impact of the adoption of ASU No. 2014-09 by segment under Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers, as reported, and ASC 605, Revenue Recognition, for the three and six months ended June 30, 2018.

In January 2016, the FASB issued ASU No. 2016-01, which updates certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Under ASU No. 2016-01, equity securities, other than those of our consolidated subsidiaries and those accounted for under the equity method, will be measured at fair value with changes in fair value recognized in the statement of operations each reporting period. ASU No. 2016-01 is effective for reporting periods beginning after December 15, 2017. There was no cumulative impact to the Company's consolidated financial statements upon adoption of ASU No. 2016-01 on January 1, 2018. The adoption of ASU No. 2016-01 increases the volatility of the Company's other income (expense), net as a result of the remeasurement of these instruments. For the three and six months endedJune 30, 2018, other income, net includes net unrealized gains related to certain equity securities that were adjusted to fair value in accordance with ASU No. 2016-01 of $126.4 million and $126.6 million, respectively. See "Note 6—Fair Value Measurements and Financial Instruments" for additional information.

In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash, which requires companies to explain the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. Therefore, amounts generally described as restricted cash or restricted cash equivalents are combined with unrestricted cash and cash equivalents when reconciling the beginning and end of period balances on the statement of cash flows. ASU No. 2016-18 also requires companies to disclose the nature of their restricted cash and restricted cash equivalents balances. Additionally, when cash, cash equivalents, restricted cash, and restricted cash equivalents are presented within different captions on the balance sheet, a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet is required. ASU No. 2016-18 is effective for reporting periods beginning after December 15, 2017. The Company's adoption of ASU No. 2016-18 effective January 1, 2018, on a retrospective basis, did not have a material effect on its consolidated financial statements.

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balance sheet to the total amounts shown in the consolidated statement of cash flows:

	June 30, 2018		December 31, 2017		June 30, 2017		December 31, 2016
	(In thousands)
Cash and cash equivalents	$	1,644,829	$	1,630,809	$	1,522,300	$	1,329,187
Restricted cash included in other current assets	347		2,873		331		20,464
Restricted cash included in other assets	—		—		—		10,548
Total cash, cash equivalents and restricted cash as shown on the consolidated statement of cash flows	$	1,645,176	$	1,633,682	$	1,522,631	$	1,360,199

Restricted cash at December 31, 2017 primarily supports a letter of credit to a supplier, which was released to the Company in the second quarter of 2018.

Restricted cash at December 31, 2016 primarily included funds held in escrow for the redemption and repurchase of IAC Senior Notes and the MyHammer tender offer. In the first quarter of 2017, the Senior Notes were redeemed and repurchased and the funds held in escrow for the MyHammer tender offer were returned to the Company.

In June 2018, the FASB issued ASU No. 2018-07, Improvements to Nonemployee Share-Based Payment Accounting, which largely aligns the measurement and classification guidance for share-based payments granted to non-employees with the guidance for share-based payments granted to employees. The new guidance supersedes Subtopic 505-50, Equity - Equity-Based payments to Nonemployees. ASU No. 2018-07 is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The Company adopted ASU No. 2018-07 effective April 1, 2018 and its adoption did not have a material effect on its consolidated financial statements. The effect of the adoption of ASU No. 2018-07 will be to minimize the volatility of expense related to stock-based awards to non-employees in the future.

Accounting Pronouncement not yet adopted by the Company

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. In July 2018, the FASB issued ASU No. 2018-11, which provides the option of an additional transition method that allows entities to initially apply the new lease guidance at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company expects to implement the transition method option provided by ASU No. 2018-11. The Company will adopt the new lease guidance effective January 1, 2019.

The Company is not a lessor, has no capitalized leases and does not expect to enter into any capitalized leases prior to the adoption of ASU No. 2016-02. Accordingly, the Company does not expect the amount or classification of rent expense in its statement of operations to be affected by the adoption of ASU No. 2016-02. The primary effect of the adoption of ASU No. 2016-02 will be the recognition of a right of use asset and related liability to reflect the Company's rights and obligations under its operating leases. The Company will also be required to provide the additional disclosures stipulated in ASU No. 2016-02.

The adoption of ASU No. 2016-02 will not have an impact on the leverage calculation set forth in any of the agreements governing the outstanding debt of the Company or its MTCH and ANGI subsidiaries, or our credit agreement or the credit agreement of MTCH because, in each circumstance, the leverage calculations are not affected by the liability that will be recorded upon adoption of the new standard.

While the Company's evaluation of the impact of the adoption of ASU No. 2016-02 on its consolidated financial statements continues, outlined below is a summary of the status of the Company's progress:

• the Company has selected a software package to assist in the determination of the right of use asset and related liability as of January 1, 2019 and to provide the required information following the adoption;

• the Company has prepared summaries of its leases for input into the software package;

• the Company is assessing the other inputs required in connection with the adoption of ASU No. 2016-02; and

• the Company is developing its accounting policy, procedures and controls related to the new standard.

The Company does not expect to have a preliminary estimate of the right of use asset and related liability as of the adoption date until the fourth quarter of 2018.

Reclassifications

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

General Revenue Recognition

General Revenue Recognition

The Company accounts for a contract when it has approval and commitment from all parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue is recognized when control of the promised services or goods is transferred to our customers, and in an amount that reflects the consideration the Company is contractually due in exchange for those services or goods.

Match Group

Match Group’s revenue is primarily derived directly from users in the form of recurring subscriptions. Subscription revenue is presented net of credits and credit card chargebacks. Subscribers pay in advance, primarily by credit card or through mobile app stores, and, subject to certain conditions identified in our terms and conditions, generally all purchases are final and nonrefundable. Revenue is initially deferred and is recognized using the straight-line method over the term of the applicable subscription period, which primarily range from one to six months. Revenue is also earned from online advertising, the purchase of à la carte features and offline events. Online advertising revenue is recognized when an advertisement is displayed. Revenue from the purchase of à la carte features is recognized based on usage. Revenue associated with offline events is recognized when each event occurs.

ANGI Homeservices

ANGI revenue is primarily derived from (i) consumer connection revenue, which comprises fees paid by service professionals for consumer matches (regardless of whether the professional ultimately provides the requested service), and (ii) membership subscription fees paid by service professionals. Consumer connection revenue varies based upon several factors, including the service requested, type of match and geographic location of service. The Company’s consumer connection revenue is generated and recognized when an in-network service professional is delivered a consumer match. Membership subscription revenue from service professionals is initially deferred and is recognized using the straight-line method over the applicable subscription period, which is typically one year. Consumer connection revenue is generally billed one week following a consumer match; with payment due upon receipt of invoice.

ANGI revenue is also derived from Angie's List (i) sales of time-based website, mobile and call center advertising to service professionals and (ii) membership subscription fees from consumers. Angie's List service professionals generally pay for advertisements in advance on a monthly or annual basis at the option of the service professional, with the average advertising contract term being approximately one year. Angie's List website, mobile and call center advertising revenue is recognized ratably over the contract term. Revenue from the sale of advertising in the Angie’s List Magazine is recognized in the period in which the publication is distributed. Angie's List prepaid consumer membership subscription fees are recognized as revenue using the straight-line method over the term of the applicable subscription period, which is typically one year.

Video

Revenue of businesses in this segment is generated primarily through subscriptions, media production and distribution, and advertising. Subscription fee revenue is recognized over the terms of the applicable subscription period, which are one month or one year, production revenue is recognized when control is transferred to the customer to broadcast or exhibit, and advertising revenue is recognized when an advertisement is displayed or over the advertising period.

Applications

Applications' revenue largely consists of advertising revenue generated principally through the display of paid listings in response to search queries. The substantial majority of the paid listings displayed by our Applications businesses are supplied to us by Google pursuant to our services agreement with Google.

Pursuant to this agreement, those of our Applications businesses that provide search services transmit search queries to Google, which in turn transmits a set of relevant and responsive paid listings back to these businesses for display in search results. This ad-serving process occurs independently of, but concurrently with, the generation of algorithmic search results for the same search queries. Google paid listings are displayed separately from algorithmic search results and are identified as sponsored listings on search results pages. Paid listings are priced on a price per click basis and when a user submits a search query through one of our Applications businesses and then clicks on a Google paid listing displayed in response to the query, Google bills the advertiser that purchased the paid listing directly and shares a portion of the fee charged to the advertiser with us. The Company recognizes paid listing revenue from Google when it delivers the user's click. In cases where the user’s click is generated due to the efforts of a third-party distributor, we recognize the amount due from Google as revenue and record a revenue share or other payment obligation to the third-party distributor as traffic acquisition costs.

To a significantly lesser extent, Applications' revenue also consists of fees related to subscription downloadable desktop and mobile applications as well as display advertisements. Fees related to subscription downloadable desktop and paid mobile applications are generally recognized at the time of the sale when the software license is delivered. To the extent updates or maintenance is required or expected, revenue is recognized over the term of the applicable subscription period, which is primarily one or two years. Fees related to display advertisements are recognized when an advertisement is displayed.

Publishing

Publishing's revenue consists principally of advertising revenue, which is generated primarily through the display of paid listings in response to search queries and display advertisements (sold directly and through programmatic ad sales). The majority of the paid listings that our Publishing businesses display are supplied to us by Google in the manner, and pursuant to the services agreement with Google, described above under "Applications."

Transaction Price

The objective of determining the transaction price is to estimate the amount of consideration the Company is due in exchange for its services or goods, including amounts that are variable. The Company determines the total transaction price, including an estimate of any variable consideration, at contract inception and reassesses this estimate each reporting period.

The Company excludes from the measurement of transaction price all taxes assessed by governmental authorities that are both (i) imposed on and concurrent with a specific revenue-producing transaction and (ii) collected from customers. Accordingly, such tax amounts are not included as a component of revenue or cost of revenue.

For contracts that have an original duration of one year or less, the Company uses the practical expedient available under ASU No. 2014-09 applicable to such contracts and does not consider the time value of money.

Accounts Receivables, net of allowance for doubtful accounts and revenue reserves

Accounts receivable include amounts billed and currently due from customers. The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivables that will not be collected. The allowance for doubtful accounts is based upon a number of factors, including the length of time accounts receivable are past due, the Company’s previous loss history and the specific customer’s ability to pay its obligation. The time between the Company issuance of an invoice and payments due date is not significant; customer payments that are not collected in advance of the transfer of promised services or goods are generally due no later than 30 days from invoice date. The Company also maintains allowances to reserve for potential credits issued to consumers or other revenue adjustments. The amounts of these reserves are based primarily upon historical experience.

Deferred Revenue

Deferred revenue consists of advance payments that are received or due in advance of the Company's performance. The Company’s liabilities are reported on a contract by contract basis at the end of each reporting period. The Company generally classifies deferred revenue as current when the term of the applicable subscription period or expected completion of our performance obligation is one year or less. The deferred revenue balance as of January 1, 2018 is $332.2 million. During the three months endedJune 30, 2018, the Company recognized $224.0 million of revenue that was included in the deferred revenue balance as of April 1, 2018. During the six months endedJune 30, 2018, the Company recognized $278.8 million of revenue that was included in the deferred revenue balance as of January 1, 2018. The current and non-current deferred revenue balances at June 30, 2018 are $375.1 million and $2.0 million, respectively. Non-current deferred revenue is included in “Other long-term liabilities” in the accompanying consolidated balance sheet.

Arrangements with Multiple Performance Obligations

The Company’s contracts with customers may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on the prices charged to customers, which are directly observable or based on an estimate if not directly observable. For our multiple performance obligation arrangements that include functional intellectual property ("IP"), which comprise the downloadable apps and software of the Applications segment, the Company uses a residual approach to determine standalone selling prices for the functional IP.

Assets Recognized from the Costs to Obtain a Contract with a Customer

The Company has determined that certain costs, primarily commissions paid to employees pursuant to certain sales incentive programs and mobile app store fees, meet the requirements to be capitalized as a cost of obtaining a contract. Commissions paid to employees pursuant to certain sales incentive programs are amortized over the estimated customer relationship period. The Company calculates the estimated customer relationship period as the average customer life, which is based on historical data. When customer renewals are expected and the renewal commission is not commensurate with the initial commission, the average customer life includes renewal periods. For sales incentive programs where the customer relationship period is one year or less, the Company has elected the practical expedient to expense the costs as incurred. The Company generally capitalizes and amortizes mobile app store fees over the term of the applicable subscription.

During the three and six months endedJune 30, 2018, the Company recognized expense of $84.7 million and $159.8 million, respectively, related to the amortization of these costs. The contract asset balance at June 30, 2018 is $72.8 million.

Performance Obligations

As permitted under the practical expedient available under ASU No. 2014-09, the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts with variable consideration that is allocated entirely to unsatisfied performance obligations or to a wholly unsatisfied promise accounted for under the series guidance, and (iii) contracts for which the Company recognizes revenue at the amount which we have the right to invoice for services performed.

________________________

^(a)  For the three and six months endedJune 30, 2018, it is more dilutive for IAC to settle certain MTCH and ANGI equity awards.  For the three and six months ended June 30, 2017, it is more dilutive for MTCH to settle certain MTCH equity awards.  The impact from ANGI’s dilutive securities is not applicable for periods prior to the Combination.

^(b)  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, warrants and subsidiary denominated equity, exchange of the Company's Exchangeable Notes and vesting of restricted stock units ("RSUs"). For the three and six months endedJune 30, 2018, 3.4 million and 6.9 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive. For the three and six months ended June 30, 2017, less than 0.1 million and 0.5 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive.

^(c)  Market-based awards and performance-based stock units (“PSUs”) are considered contingently issuable shares. Shares issuable upon exercise or vesting of market-based awards and PSUs are included in the denominator for earnings per share if (i) the applicable market or performance condition(s) has been met and (ii) the inclusion of the market-based awards and PSUs is dilutive for the respective reporting periods. For both the three and six months endedJune 30, 2018, 0.2 million shares underlying market-based awards and PSUs were excluded from the calculation of diluted earnings per share because the market or performance conditions had not been met. For both the three and six months ended June 30, 2017, 0.4 million shares underlying market-based awards and PSUs were excluded from the calculation of diluted earnings per share because the market or performance conditions had not been met.

^(d)  It is the Company's intention to settle the Exchangeable Notes through a combination of cash, equal to the face amount of the notes, and shares; therefore, the Exchangeable Notes are only dilutive for periods during which the average price of IAC common stock exceeds the approximate $152.18 per share exchange price per $1,000 principal amount of the Exchangeable Notes.

________________________

^(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 businesses, and this measure is one of the primary metrics on 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. Adjusted EBITDA has certain limitations in that it does not take into account the impact to IAC's statement of operations of certain expenses.
