Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

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

Basis of Consolidation and Accounting for Investments

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

Investments in the common stock or in-substance common stock of entities in which the Company has the ability to exercise significant influence over the operating and financial matters of the investee, but does not have a controlling financial interest, are accounted for using the equity method. Investments in the common stock or in-substance common stock of entities in which the Company does not have the ability to exercise significant influence over the operating and financial matters of the investee are accounted for using the cost method. Investments in companies that IAC does not control, which are not in the form of common stock or in-substance common stock, are also accounted for using the cost method. The Company evaluates each cost and equity method investment for impairment on a quarterly basis and recognizes an impairment loss if a decline in value is determined to be other-than-temporary. Such impairment evaluations include, but are not limited to: the current business environment, including competition; going concern considerations such as financial condition, the rate at which the investee utilizes cash and the investee's ability to obtain additional financing to achieve its business plan; the need for changes to the investee's existing business model due to changing business and regulatory environments and its ability to successfully implement necessary changes; and comparable valuations. If the Company has not identified events or changes in circumstances that may have a significant adverse effect on the fair value of a cost method investment, then the fair value of such cost method investment is not estimated, as it is impracticable to do so.

Accounting Estimates

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

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

Revenue Recognition

The Company recognizes revenue when persuasive evidence of an arrangement exists, services are rendered or merchandise is delivered to customers, the fee or price charged is fixed or determinable and collectability is reasonably assured. Deferred revenue is recorded when payments are received, or contractually due, in advance of the Company's rendering of services or delivery of merchandise.

Match Group

Revenue of the dating businesses is substantially derived directly from users in the form of recurring membership fees for subscription-based online personals and related services. Membership revenue is presented net of credits and credit card chargebacks. Revenue is recognized ratably over the terms of the applicable membership, which primarily range from one to six months. Members pay in advance, primarily by using a credit card, and, subject to certain conditions identified in our terms and conditions, all purchases are final and nonrefundable. Deferred revenue is recognized using the straight-line method over the terms of the applicable membership period. Deferred revenue at Dating is $144.4 million and $117.9 million at December 31, 2015 and 2014, respectively. Revenue is also earned from online advertising, the purchase of à la carte features and offline events. Online advertising revenue is recognized every time an advertisement is displayed. Revenue from the purchase of à la carte features is recognized based on usage. Revenue and the related expenses associated with offline events are recognized when each event occurs.

Non-dating's revenue consists primarily of fees received directly from students for in-person and online test preparation classes, access to online test preparation materials and individual tutoring services. Fees from classes and access to online materials are recognized over the period of the course and the period of the online access, respectively. Tutoring fees are recognized based on usage. Deferred revenue at Non-dating is $25.7 million and $18.0 million at December 31, 2015 and 2014, respectively.

HomeAdvisor

HomeAdvisor's lead acceptance revenue is generated and recognized when an in-network home service professional is delivered a consumer lead. HomeAdvisor's membership subscription revenue is generated through subscription sales to service professionals and is deferred and recognized over the terms of the memberships, which are one month, three months, or one year. HomeAdvisor's website hosting revenue is deferred and recognized over the period of the hosting agreement. Deferred revenue at HomeAdvisor is $11.9 million and $4.9 million at December 31, 2015 and 2014, respectively.

Publishing

Publishing's revenue consists principally of advertising revenue, which is generated primarily through the display of paid listings in response to search queries, display advertisements and fees related to paid mobile downloadable applications. The substantial majority of the paid listings that our Publishing businesses display are supplied to us by Google Inc. ("Google") pursuant to our services agreement with Google. Pursuant to this agreement, those of our Publishing 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 Publishing 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. We recognize 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.

Applications

Substantially all of Applications' revenue 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 in the manner and pursuant to the services agreement described above under "Publishing". To a significantly lesser extent, Applications' revenue also consists of fees related to subscription downloadable applications which are recognized over the terms of the applicable subscriptions, primarily one to two years, and fees related to paid mobile downloadable applications and display advertisements, which are recognized at the time of the sale and when the ad is displayed, respectively. Deferred revenue at SlimWare is $21.0 million and $14.5 million at December 31, 2015 and 2014, respectively.

Video

Revenue of businesses included in this segment is generated primarily through media production and distribution, subscriptions and advertising. Production revenue is recognized when the production is available for the customer to broadcast or exhibit, subscription fee revenue is recognized over the terms of the applicable subscriptions, which are one month or one year, and advertising revenue is recognized when an ad is displayed or over the period earned. Deferred revenue at Vimeo is $30.4 million and $25.4 million at December 31, 2015 and 2014, respectively. Deferred revenue at Electus, CollegeHumor and Notional totals $24.4 million and $14.0 million at December 31, 2015 and 2014, respectively.

Other

ShoeBuy's revenue consists of merchandise sales, reduced by incentive discounts and sales returns, and is recognized when delivery to the customer has occurred. Delivery is considered to have occurred when the customer takes title and assumes the risks and rewards of ownership, which is on the date of shipment. Accruals for returned merchandise are based on historical experience. Shipping and handling fees billed to customers are recorded as revenue. The costs associated with shipping goods to customers are recorded as cost of revenue.

PriceRunner's revenue consists principally of advertising revenue that, depending on the terms of the arrangement, is recognized when a user clicks on an ad, or when a user clicks-through on the ad and takes a specified action on the destination site.

Cash and Cash Equivalents

Cash and cash equivalents include cash and short-term investments, with maturities of less than 91 days from the date of purchase. Domestically, cash equivalents primarily consist of AAA rated money market funds and commercial paper rated A2/P2 or better. Internationally, cash equivalents primarily consist of time deposits and AAA rated money market funds.

Marketable Securities

At December 31, 2015, marketable securities consist of short-to-medium-term debt securities issued by investment grade corporate issuers and an equity security. The Company invests in marketable debt securities with active secondary or resale markets to ensure portfolio liquidity to fund current operations or satisfy other cash requirements as needed. The Company also invests in marketable equity securities as part of its investment strategy. All marketable securities are classified as available-for-sale and are reported at fair value. The unrealized gains and losses on marketable securities, net of tax, are included in accumulated other comprehensive income as a separate component of shareholders' equity. The specific-identification method is used to determine the cost of securities sold and the amount of unrealized gains and losses reclassified out of accumulated other comprehensive income into earnings.

The Company employs a methodology that considers available evidence in evaluating potential other-than-temporary impairments of its investments. Investments are considered to be impaired when a decline in fair value below the amortized cost basis is determined to be other-than-temporary. Factors considered in determining whether a loss is other-than-temporary include the length of time and extent to which fair value has been less than the amortized cost basis, the financial condition and near-term prospects of the issuer, and whether it is not more likely than not that the Company will be required to sell the security before the recovery of the amortized cost basis, which may be maturity. If a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded in current earnings and a new cost basis in the investment is established.

Certain Risks and Concentrations

A substantial portion of the Company's revenue is derived from online advertising, the market for which is highly competitive and rapidly changing. Significant changes in this industry or changes in advertising spending behavior or in customer buying behavior could adversely affect our operating results. Most of the Company's online advertising revenue is attributable to a services agreement with Google. On October 26, 2015, the Company and Google entered into a services agreement that is effective as of April 1, 2016, following the expiration of the current services agreement, and expires on March 31, 2020. The Company may choose to terminate the agreement effective March 31, 2019. These services agreements require that we comply with certain guidelines promulgated by Google. Google may generally unilaterally update its own policies and guidelines without advance notice, which could in turn require modifications to, or prohibit and/or render obsolete certain of our products, services and/or business practices, which could be costly to address or otherwise have an adverse effect on our business, financial condition and results of operations. For the years ended December 31, 2015, 2014 and 2013, revenue earned from Google is $1.3 billion, $1.4 billion and $1.5 billion, respectively. This revenue is earned by the businesses comprising the Publishing and Applications segments. For the years ended December 31, 2015, 2014 and 2013, Google revenue represents 83% and 94%; 83% and 97%; and 83% and 98%, of Publishing and Applications revenue, respectively. Accounts receivable related to revenue earned from Google totaled $97.2 million and $118.7 million at December 31, 2015 and 2014, respectively.

The Company's business is subject to certain risks and concentrations including dependence on third-party technology providers, exposure to risks associated with online commerce security and credit card fraud.

Financial instruments, which potentially subject the Company to concentration of credit risk, consist primarily of cash and cash equivalents and marketable securities. Cash and cash equivalents are maintained with financial institutions and are in excess of Federal Deposit Insurance Corporation insurance limits.

Accounts Receivable

Accounts receivable are stated at amounts due from customers, net of an allowance for doubtful accounts and revenue reserves. Accounts receivable outstanding longer than the contractual payment terms are considered past due. The Company determines its allowance by considering a number of factors, including the length of time accounts receivable are past due, the Company's previous loss history, the specific customer's ability to pay its obligation to the Company and the condition of the general economy and the customer's industry. The Company writes off accounts receivable when they become uncollectible. The Company also maintains allowances to reserve for potential credits issued to customers or other revenue adjustments. The amounts of these reserves are based, in part, on historical experience.

Property and Equipment

Property and equipment, including significant improvements, are recorded at cost. Repairs and maintenance costs are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the assets.



Asset Category	Estimated Useful Lives
Buildings and leasehold improvements	3 to 39 Years
Computer equipment and capitalized software	2 to 3 Years
Furniture and other equipment	3 to 12 Years

The Company capitalizes certain internal use software costs including external direct costs utilized in developing or obtaining the software and compensation for personnel directly associated with the development of the software. Capitalization of such costs begins when the preliminary project stage is complete and ceases when the project is substantially complete and ready for its intended purpose. The net book value of capitalized internal use software is $39.6 million and $36.9 million at December 31, 2015 and 2014, respectively.

Business Combinations

The purchase price of each acquisition is attributed to the assets acquired and liabilities assumed based on their fair values at the date of acquisition, including identifiable intangible assets that either arise from a contractual or legal right or are separable from goodwill. The fair value of these intangible assets is based on detailed valuations that use information and assumptions provided by management. The excess purchase price over the net tangible and identifiable intangible assets is recorded as goodwill

In connection with some business combinations, the Company has entered into contingent consideration arrangements that are determined to be part of the purchase price. Each of these arrangements are recorded at its fair value at the time of the acquisition and reflected at current fair value for each subsequent reporting period thereafter until settled. The contingent consideration arrangements are generally based upon earnings performance and/or operating metrics such as monthly active users. The Company determines the fair value of the contingent consideration arrangements using probability-weighted analyses to determine the amounts of the gross liability, and, if the arrangement is long-term in nature, applying a discount rate that appropriately captures the risk associated with the obligation to determine the net amount reflected in the consolidated financial statements. Determining the fair value of these arrangements is inherently difficult and subjective. Significant changes in forecasted earnings or operating metrics would result in a significantly higher or lower fair value measurement and can have a material impact on our consolidated financial statements. The changes in the remeasured fair value of the contingent consideration arrangements each reporting period, including the accretion of the discount, if applicable, are recognized in “General and administrative expense” in the accompanying consolidated statement of operations. See Note 7 for a discussion of contingent consideration arrangements.

Goodwill and Indefinite-Lived Intangible Assets

Goodwill acquired in business combinations is assigned to the reporting unit(s) that is expected to benefit from the combination as of the acquisition date. The Company assesses goodwill and indefinite-lived intangible assets for impairment annually as of October 1, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit or the fair value of an indefinite-lived intangible asset below its carrying value.

The Company has the option to qualitatively assess whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. For the Company's annual goodwill test at October 1, 2015, a quantitative assessment of the Match Group, Publishing, Applications, ShoeBuy and PriceRunner reporting units' goodwill was performed. A qualitative assessment of the HomeAdvisor, Connected Ventures, and DailyBurn reporting units' goodwill was performed. When the Company elects to perform a qualitative assessment and concludes it is not more likely than not that the fair value of the reporting unit is less than its carrying value, no further assessment of that reporting unit's goodwill is necessary; otherwise, the fair value of the reporting unit has to be determined and if the carrying value of a reporting unit's goodwill exceeds its implied fair value, an impairment loss equal to the excess is recorded.

The Company determines the fair values of its reporting units using both an income approach based on discounted cash flows ("DCF") and a market approach. Determining fair value using a DCF analysis requires the exercise of significant judgment with respect to several items, including the judgment about the amount and timing of expected future cash flows and appropriate discount rates. The expected cash flows used in the DCF analyses are based on the Company's most recent budget and, for years beyond the budget, the Company's estimates, which are based, in part, on forecasted growth rates. The discount rates used in the DCF analyses are intended to reflect the risks inherent in the expected future cash flows of the respective reporting units. Assumptions used in the DCF analyses, including the discount rate, are assessed annually based on each reporting unit's current results and forecast, as well as macroeconomic and industry specific factors. The discount rates used in the Company's annual goodwill impairment assessment ranged from 12% to 22% in 2015 and 13% to 19% in 2014. Determining fair value using a market approach considers multiples of financial metrics based on both acquisitions and trading multiples of a selected peer group of companies. From the comparable companies, a representative market multiple is determined which is applied to financial metrics to estimate the fair value of a reporting unit. To determine a peer group of companies for our respective reporting units, we considered companies relevant in terms of consumer use, monetization model, margin and growth characteristics and brand strength operating in their respective sectors.

While the Company has the option to qualitatively assess whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying value, the Company's policy is to determine the fair value of each of its indefinite-lived intangible assets annually as of October 1. The Company determines the fair values of its indefinite-lived intangible assets using avoided royalty DCF analyses. Significant judgments inherent in these analyses include the selection of appropriate royalty and discount rates and estimating the amount and timing of expected future cash flows. The discount rates used in the DCF analyses reflect the risks inherent in the expected future cash flows generated by the respective intangible assets. The royalty rates used in the DCF analyses are based upon an estimate of the royalty rates that a market participant would pay to license the Company's trade names and trademarks. Assumptions used in the avoided royalty DCF analyses, including the discount rate and royalty rate, are assessed annually based on the actual and projected cash flows related to the asset, as well as macroeconomic and industry specific factors. The discount rates used in the Company's annual indefinite-lived impairment assessment ranged from 11% to 16% in 2015 and 10% to 20% in 2014, and the royalty rates used ranged from 1% to 9% in both 2015 and 2014.

In connection with the annual assessments in 2015, the Company identified and recorded impairment charges of $88.0 million related to certain indefinite-lived intangible assets at the Publishing segment and $14.1 million at the Other segment related to goodwill at ShoeBuy. At October 1, 2015, the date of our most recent annual impairment assessment, the fair value of the Company's reporting units exceeded their carrying values by more than 20% with the exception of Publishing and ShoeBuy. The indefinite-lived intangible asset impairment charge at Publishing related to certain trade names of certain Ask & Other direct marketing brands, including Ask.com. The impairment charge reflects the impact of recent Google ecosystem changes that have impacted our ability to market, the effect of the reduced revenue share on mobile under the terms of the services agreement with Google, which was entered into on October 26, 2015, and the shift in focus to higher margin businesses in Publishing's Premium Brands. The combined impact of these factors has reduced the forecasted revenue and profits for these brands and the impairment charge reflects the resultant reduction in fair value. The impairment charge is included in "Amortization of intangibles" in the accompanying consolidated statement of operations. The goodwill impairment charge at ShoeBuy was due to increased investment and the seasonal effect of high inventory levels as of October 1, 2015, the date of our most recent annual assessment. The 2014 and 2013 annual assessments identified no material impairments.

To illustrate the magnitude of a potential impairment charge relative to future changes in estimated fair value, had the estimated fair value of Publishing and ShoeBuy been hypothetically lower by 10% and 20% as of October 1, 2015, the carrying value of Publishing would have exceeded its fair value by approximately $20 million and $60 million, respectively, and the carrying value of ShoeBuy would have exceeded its fair value by approximately $1 million and $5 million, respectively.

The Company's reporting units are consistent with its determination of its operating segments. Goodwill is tested for impairment at the reporting unit level. See Note 13 for additional information regarding the Company's method of determining operating and reportable segments.

Long-Lived Assets and Intangible Assets with Definite Lives

Long-lived assets, which consist of property and equipment and intangible assets with definite lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. The carrying value of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying value is deemed not to be recoverable, an impairment loss is recorded equal to the amount by which the carrying value of the long-lived asset exceeds its fair value. Amortization of definite-lived intangible assets is computed either on a straight-line basis or based on the pattern in which the economic benefits of the asset will be realized.

Fair Value Measurements

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


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

•

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


•	Level 3: Unobservable inputs for which there is little or no market data and require the Company to develop its own assumptions, based on the best information available in the circumstances, about the assumptions market participants would use in pricing the assets or liabilities. See Note 7 for a discussion of fair value measurements made using Level 3 inputs.

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

Traffic Acquisition Costs

Traffic acquisition costs consist of payments made to partners who distribute our Partnerships customized browser-based applications, integrate our paid listings into their websites and fees related to the distribution and facilitation of in-app purchase of product features. These payments include amounts based on revenue share and other arrangements. The Company expenses these payments in the period incurred as a component of cost of revenue.

Advertising Costs

Advertising costs are expensed in the period incurred (when the advertisement first runs for production costs that are initially capitalized) and represent online marketing, including fees paid to search engines and third parties that distribute our Consumer downloadable applications, offline marketing, which is primarily television advertising, and partner-related payments to those who direct traffic to the Match Group brands. Advertising expense is $1.2 billion, $994.7 million and $850.4 million for the years ended December 31, 2015, 2014 and 2013, respectively.

The Company capitalizes and amortizes the costs associated with certain distribution arrangements that require it to pay a fee per access point delivered. These access points are generally in the form of downloadable applications associated with our Consumer operations. These fees are amortized over the estimated useful lives of the access points to the extent the Company can reasonably estimate a probable future economic benefit and the period over which such benefit will be realized (generally 18 months). Otherwise, the fees are charged to expense as incurred.

Legal Costs

Legal costs are expensed as incurred.

Income Taxes

The Company recognizes liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement.

The Company accounts for income taxes under the liability method, and deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying values of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. A valuation allowance is provided on deferred tax assets if it is determined that it is more likely than not that the deferred tax asset will not be realized. The Company records interest, net of any applicable related income tax benefit, on potential income tax contingencies as a component of income tax expense.

Earnings Per Share

Basic earnings per share is computed by dividing net earnings attributable to IAC shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur if stock options and other commitments to issue common stock were exercised or equity awards vested resulting in the issuance of common stock that could share in the earnings of the Company.

Foreign Currency Translation and Transaction Gains and Losses

The financial position and operating results of foreign entities whose primary economic environment is based on their local currency are consolidated using the local currency as the functional currency. These local currency assets and liabilities are translated at the rates of exchange as of the balance sheet date, and local currency revenue and expenses of these operations are translated at average rates of exchange during the period. Translation gains and losses are included in accumulated other comprehensive income as a component of shareholders' equity. Transaction gains and losses resulting from assets and liabilities denominated in a currency other than the functional currency are included in the consolidated statement of operations as a component of other (expense) income, net.

Translation gains and losses relating to foreign entities that are liquidated or substantially liquidated are reclassified out of accumulated other comprehensive income (loss) into earnings. Such gains totaled $2.2 million during the year ended December 31, 2015, and are included in "Other income (expense), net" in the accompanying consolidated statement of operations.

Stock-Based Compensation

Stock-based compensation is measured at the grant date based on the fair value of the award and is generally expensed over the requisite service period. See Note 12 for a discussion of the Company's stock-based compensation plans.

Redeemable Noncontrolling Interests

Noncontrolling interests in the consolidated subsidiaries of the Company should ordinarily be reported on the consolidated balance sheet within shareholders' equity, separately from the Company's equity. However, securities that are redeemable at the option of the holder and not solely within the control of the issuer must be classified outside of shareholders' equity. Accordingly, if redemption of the noncontrolling interests is outside the control of the Company, the interests are included outside of shareholders' equity in the accompanying consolidated balance sheet.

In connection with the acquisition of certain subsidiaries, management of these businesses has retained an ownership interest. The Company is party to fair value put and call arrangements with respect to these interests. These put and call arrangements allow management of these businesses to require the Company to purchase their interests or allow the Company to acquire such interests at fair value, respectively. The put arrangements do not meet the definition of a derivative instrument as the put agreements do not provide for net settlement. These put and call arrangements become exercisable by the Company and the counter-party at various dates in the future. During both the years ended December 31, 2015 and 2013 two of these arrangements were exercised. No put or call arrangements were exercised during 2014. These put arrangements are exercisable by the counter-party outside the control of the Company. Accordingly, to the extent that the fair value of these interests exceeds the value determined by normal noncontrolling interest accounting, the value of such interests is adjusted to fair value with a corresponding adjustment to additional paid-in capital. During the years ended December 31, 2015, 2014 and 2013, the Company recorded adjustments of $23.2 million, $27.8 million and $40.6 million, respectively, to increase these interests to fair value. Fair value determinations require high levels of judgment and are based on various valuation techniques, including market comparables and discounted cash flow projections.

Noncontrolling Interests

Noncontrolling interests at December 31, 2015 relate to the public's ownership interest in Match Group following its IPO on November 24, 2015.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers, which clarifies the principles for recognizing revenue and develops a common standard for all industries. In July 2015, the FASB decided to defer the effective date for annual reporting periods beginning after December 15, 2017. Early adoption is permitted beginning on the original effective date of December 15, 2016. Upon adoption, ASU No. 2014-09 may either be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. The Company is currently evaluating the new guidance and has not yet determined whether the adoption of the new standard will have a material impact on its consolidated financial statements or the method and timing of adoption.

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes, which requires that deferred tax assets and liabilities be classified as non-current in the balance sheet. Prior to the issuance of the standard, deferred tax assets and liabilities were required to be separately classified into a current amount and a non-current amount in the balance sheet. The new guidance is required to be adopted in annual periods beginning after December 15, 2016. Early adoption is permitted and may be applied prospectively or retrospectively. The Company has elected to early adopt the guidance as of December 31, 2015 and to apply the guidance retrospectively to all periods presented. The adoption of ASU 2015-17 did not have a material effect on the Company's consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which supersedes existing guidance on accounting for leases in "Leases (Topic 840)" and generally requires all leases to be recognized in the statement of financial position. The provisions of ASU 2016-02 are effective for reporting periods beginning after December 15, 2018; early adoption is permitted. The provisions of ASU 2016-02 are to be applied using a modified retrospective approach. The Company is currently evaluating the new guidance and has not yet determined whether the adoption of the new standard will have a material impact on its consolidated financial statements.

Reclassifications

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

At December 31, 2015, the Company has federal and state net operating losses ("NOLs") of $74.3 million and $96.1 million, respectively. If not utilized, the federal NOLs will primarily expire at various times between 2030 and 2035, and the state NOLs will expire at various times between 2016 and 2035. Utilization of federal and state NOLs will be subject to limitations under Section 382 of the Internal Revenue Code and applicable state law. At December 31, 2015, the Company has foreign NOLs of $132.3 million available to offset future income. Of these foreign NOLs, $115.7 million can be carried forward indefinitely and $16.6 million will expire at various times between 2015 and 2035. During 2015, the Company recognized tax benefits related to NOLs of $2.7 million. At December 31, 2015, the Company has federal and state capital losses of $2.2 million and $20.8 million, respectively. If not utilized, the capital losses will expire between 2016 and 2020. Utilization of capital losses will be limited to the Company's ability to generate future capital gains.

At December 31, 2015, the Company has tax credit carryforwards of $18.5 million. Of this amount, $6.6 million relates to state tax credits for research activities, $6.2 million relates to federal credits for foreign taxes, and $5.7 million relates to various state and local tax credits. Of these credit carryforwards, $8.6 million can be carried forward indefinitely and $9.9 million will expire within ten years.

During 2015, the Company's valuation allowance decreased by $7.9 million primarily due to the realization of certain deferred tax assets, partially offset by an increase in unrealized net operating and capital losses. At December 31, 2015, the Company has a valuation allowance of $90.5 million related to the portion of tax loss carryforwards and other items for which it is more likely than not that the tax benefit will not be realized.

A reconciliation of the income tax provision to the amounts computed by applying the statutory federal income tax rate to earnings from continuing operations before income taxes is shown as follows:

No income taxes have been provided on indefinitely reinvested earnings of certain foreign subsidiaries aggregating $555.9 million at December 31, 2015. The estimated amount of the unrecognized deferred income tax liability with respect to such earnings is $127.2 million.

A reconciliation of the beginning and ending amount of unrecognized tax benefits, excluding interest, is as follows:

The Company recognizes interest and, if applicable, penalties related to unrecognized tax benefits in the income tax provision. Included in the income tax provision for continuing operations for the years ended December 31, 2015, 2014 and 2013 is a $0.1 million expense, $58.5 million benefit and $4.8 million expense, respectively, net of related deferred taxes of less than $0.1 million, $35.3 million and $2.8 million, respectively, for interest on unrecognized tax benefits. Included in the income tax provision for discontinued operations for the years ended December 31, 2015, 2014 and 2013 is a less than $0.1 million benefit, $19.7 million benefit and $1.4 million expense, respectively, net of related deferred taxes of less than $0.1 million, $11.7 million and $0.8 million, respectively, for interest on unrecognized tax benefits. At December 31, 2015 and 2014, the Company has accrued $2.5 million and $2.8 million, respectively, for the payment of interest. At December 31, 2015 and 2014, the Company has accrued $2.2 million and $2.9 million, respectively, for penalties.

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

At December 31, 2015 and 2014, unrecognized tax benefits, including interest, were $43.4 million and $33.2 million, respectively. If unrecognized tax benefits at December 31, 2015 are subsequently recognized, $41.0 million, net of related deferred tax assets and interest, would reduce income tax expense. The comparable amount as of December 31, 2014 was $30.5 million. The Company believes that it is reasonably possible that its unrecognized tax benefits could decrease by approximately $8.1 million by December 31, 2016, primarily due to expirations of statutes of limitations; $7.7 million of which would reduce the income tax provision for continuing operations.

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

The additions primarily relate to Match Group's acquisitions of PlentyOfFish and Eureka. See Note 2 for information on the current year impairment charge at ShoeBuy.

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

The gross unrealized losses on the marketable debt securities relate primarily to changes in interest rates. The Company does not consider the gross unrealized losses to be other-than-temporary because the Company does not intend to sell the marketable debt securities that generated the gross unrealized losses at December 31, 2015, and it is not more likely than not that the Company will be required to sell these securities before recovery of their amortized costs bases, which may be maturity.

The unrealized gains and losses in the tables above are included in "Accumulated other comprehensive loss" in the accompanying consolidated balance sheet.

There are no investments in current available-for-sale marketable debt securities that have been in a continuous unrealized loss position for longer than twelve months as of December 31, 2015.

There were no gross realized losses from the maturities and sales of available-for-sale marketable securities for the years ended December 31, 2015, 2014 and 2013. However, during the second quarter of 2015, the Company recognized $0.3 million in losses that were deemed to be other-than-temporary related to various corporate debt securities that were expected to be sold by the Company, in part, to fund its cash needs related to Match Group's acquisition of PlentyOfFish for $575 million.

Auction rate security	4,050		6,070
Total long-term investments	$	137,386	$	114,983

Cost method investments

In 2015 and 2014, the Company recorded $4.5 million and $66.6 million, respectively, of other-than-temporary impairment charges for certain cost method investments as a result of our assessment of the near-term prospects and financial condition of the investees. These charges are included in "Other income (expense), net" in the accompanying consolidated statement of operations.

The Company, through Match Group, has a 21% interest in the voting common stock of Zhenai Inc. ("Zhenai"), a leading provider of online dating and matchmaking services in China. However, given the significance of our interest relative to other shareholders, we do not have the ability to exercise significant influence over the operating and financial matters of Zhenai and this investment is accounted for as a cost method investment.

Equity method investments

In 2014, the Company recorded a $4.2 million other-than-temporary impairment charge on one of its investments following the sale of a majority of the investee's assets. These charges are included in "Equity in losses of unconsolidated affiliates" in the accompanying consolidated statement of operations.

Long-term marketable equity security

The cost basis of the Company's long-term marketable equity security at December 31, 2015 and 2014 is $5.0 million and $8.7 million, respectively, with a gross unrealized gain of $2.6 million and a gross unrealized loss of $1.2 million, respectively. The gross unrealized gain at December 31, 2015 and gross unrealized loss at December 31, 2014 are included in "Accumulated other comprehensive loss" in the accompanying consolidated balance sheet.

Auction rate security

The Company's auction rate security is valued by discounting the estimated future cash flow streams of the security over the life of the security. Credit spreads and other risk factors are also considered in establishing fair value. The cost basis of the auction rate security is $10.0 million, with a gross unrealized loss of $5.9 million and $3.9 million at December 31, 2015 and December 31, 2014, respectively. The unrealized losses are included in "Accumulated other comprehensive loss" in the accompanying consolidated balance sheet. At December 31, 2015, the auction rate security is rated BBB- and matures in 2035. The Company does not consider the auction rate security to be other-than-temporarily impaired at December 31, 2015, due to its high credit rating and because the Company does not intend to sell this security, and it is not more likely than not that the Company will be required to sell this security, before the recovery of its amortized cost basis, which may be maturity.

Contingent consideration arrangements

As of December 31, 2015, there are nine contingent consideration arrangements related to business acquisitions. Eight of the contingent consideration arrangements have limits as to the maximum amount that can be paid; the maximum contingent payments related to these arrangements are $240.7 million and the fair value of these arrangements at December 31, 2015 is $33.4 million. The fair value of the one contingent consideration arrangement without a limit on the maximum amount is $0.4 million at December 31, 2015. The contingent consideration arrangements are generally based upon earnings performance and/or operating metrics such as monthly active users. The Company determines the fair value of the contingent consideration arrangements by using probability-weighted analyses to determine the amounts of the gross liability, and, if the arrangement is long-term in nature, applying a discount rate that appropriately captures the risks associated with the obligation to determine the net amount reflected in the consolidated financial statements. The number of scenarios in the probability-weighted analyses can vary; generally, more scenarios are prepared for longer duration and more complex arrangements. The fair values of the contingent consideration arrangements at December 31, 2015 reflect discount rates ranging from 12% to 25%.

The fair values of the contingent consideration arrangements are sensitive to changes in the forecasts of earnings and/or the relevant operating metrics and changes in discount rates. The Company remeasures the fair value of the contingent consideration arrangements each reporting period, including the accretion of the discount, if applicable, and changes are recognized in “General and administrative expense” in the accompanying consolidated statement of operations. The contingent consideration arrangement liability at December 31, 2015 includes a current portion of $2.6 million and non-current portion of $31.2 million, which are included in “Accrued expenses and other current liabilities” and “Other long-term liabilities,” respectively, in the accompanying consolidated balance sheet.

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:



	December 31, 2015						December 31, 2014

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

The 2013 and 2012 Senior Notes were issued by IAC on November 15, 2013 and December 21, 2012, respectively. The 2013 and 2012 Senior Notes are unconditionally guaranteed by certain wholly-owned domestic subsidiaries, which are designated as guarantor subsidiaries. The guarantor subsidiaries are the same for the 2013 and 2012 Senior Notes. See Note 20 for guarantor and non-guarantor financial information.

The indenture governing the 2013 Senior Notes contains covenants that would limit our ability to pay dividends or to make distributions and repurchase or redeem our stock in the event a default has occurred or we not in compliance with the maximum leverage ratio of 3.0 to 1.0. At December 31, 2015, there were no limitations pursuant thereto. There are additional covenants that limit the Company's ability and the ability of its restricted subsidiaries to, among other things, (i) incur indebtedness, make investments, or sell assets in the event we are not in compliance with the financial ratio set forth in the indenture, and (ii) incur liens, enter into agreements limiting our restricted subsidiaries' ability to pay dividends, enter into transactions with affiliates and consolidate, merge or sell substantially all of our assets. The indenture governing the 2012 Senior Notes was amended in connection with the Match Exchange Offer described below. This indenture amendment eliminated substantially all of the restrictive covenants contained therein.

On October 7, 2015, IAC's $300 million revolving credit facility (the "IAC Credit Facility") was amended and restated, and now expires October 7, 2020. At December 31, 2015 and 2014, there were no outstanding borrowings under the IAC Credit Facility. The annual commitment fee on undrawn funds is currently 35 basis points, and is based on the leverage ratio most recently reported. Borrowings under the IAC Credit Facility bear interest, at the Company's option, at either 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 the same domestic subsidiaries that guarantee the 2013 and 2012 Senior Notes and are also secured by the stock of certain of our domestic and foreign subsidiaries. The 2013 Senior Notes and 2012 Senior Notes rank pari-passu with each other, and are subordinate to outstanding borrowings under the IAC Credit Facility.

On November 16, 2015, Match Group completed a private exchange offer to eligible holders to exchange any and all of the 2012 Senior Notes for up to $500 million aggregate principal amount of Match Group Senior Notes issued by Match Group ("Match Exchange Offer"). Match Group exchanged $445.3 million of 2012 Senior Notes for $445.2 million of Match Group Senior Notes pursuant to the Match Exchange Offer. Promptly following the closing of the Match Exchange Offer, Match Group and its subsidiaries were designated as unrestricted subsidiaries of IAC for purposes of the indentures governing the 2013 and 2012 Senior Notes and the IAC Credit Facility. Following the designation, neither Match Group nor any of its subsidiaries guaranteed any debt of IAC, or are subject to any of the covenants related to such debt.

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

On October 7, 2015, Match Group entered into a credit agreement (the "Match Group Credit Agreement") which provides for a five-year $500 million revolving credit facility (the "Match Group Credit Facility"). At December 31, 2015, there were no outstanding borrowings under the Match Group Credit Facility. The annual commitment fee on undrawn funds is currently 35 basis points, and is based on the leverage ratio most recently reported. Borrowings under the Match Group Credit Facility bear interest, at Match Group's option, at either a base rate or LIBOR, in each case plus an applicable margin, which is determined by reference to a pricing grid based on Match Group's consolidated net leverage ratio. The terms of the Match Group Credit Facility require Match Group to maintain a leverage ratio of not more than 5.0 to 1.0 and a minimum interest coverage ratio of not less than 2.5 to 1.0.

On November 16, 2015, Match Group amended and restated the Match Group Credit Agreement to provide for an $800 million, seven-year term loan ("Match Group Term Loan"). Principal payments of $10 million under the Match Group Term Loan are due quarterly through maturity, at which point a final principal payment of $530 million will become due. Additionally, the Match Group Term Loan may require additional annual principal payments as part of an excess cash flow sweep provision, the amount of which is governed by the net secured leverage ratio. The Match Group Term Loan bears interest, at its option, at either the base rate or LIBOR, plus 3.50% or 4.50%, respectively, with, in the case of LIBOR, a floor of 1.00%. Interest payments are due no less than semi-annually through the term of the loan. The Match Group Term Loan and outstanding borrowings, if any, under the Match Group Credit Facility rank pari-passu with each other, and have priority over the Match Group Senior Notes.

There are additional covenants under the Match Group Credit Facility and the Match Group Term Loan that limit Match Group's ability and the ability of its subsidiaries to, among other things, incur indebtedness, pay dividends or make distributions. While the Match Group Term Loan remains outstanding, these same covenants under the Match Group Credit Agreement are more restrictive than the covenants that are applicable to the Match Group Credit Facility. Obligations under the Match Group Credit Facility and Match Group Term Loan are unconditionally guaranteed by certain wholly-owned Match Group domestic subsidiaries, and are also secured by the stock of certain Match Group domestic and foreign subsidiaries.

The Company may redeem the 2013 Senior Notes at the redemption prices set forth below, together with accrued and unpaid interest thereon to the applicable redemption date, if redeemed during the twelve-month period beginning on November 30 of the years indicated below:

SHAREHOLDERS' EQUITY	12 Months Ended
SHAREHOLDERS' EQUITY	Dec. 31, 2015
Stockholders' Equity Note [Abstract]
SHAREHOLDERS' EQUITY	SHAREHOLDERS' EQUITY Description of Common Stock and Class B Convertible Common Stock Each holder of shares of IAC common stock and IAC Class B common stock vote together as a single class with respect to matters that may be submitted to a vote or for the consent of IAC's shareholders generally, including the election of directors. In connection with any such vote, each holder of IAC common stock is entitled to one vote for each share of IAC common stock held and each holder of IAC Class B common stock is entitled to ten votes for each share of IAC Class B common stock held. Notwithstanding the foregoing, the holders of shares of IAC common stock, acting as a single class, are entitled to elect 25% of the total number of IAC's directors, and, in the event that 25% of the total number of directors shall result in a fraction of a director, then the holders of shares of IAC common stock, acting as a single class, are entitled to elect the next higher whole number of IAC's directors. In addition, Delaware law requires that certain matters be approved by the holders of shares of IAC common stock or holders of IAC Class B common stock voting as a separate class. Shares of IAC Class B common stock are convertible into shares of IAC common stock at the option of the holder thereof, at any time, on a share-for-share basis. Such conversion ratio will in all events be equitably preserved in the event of any recapitalization of IAC by means of a stock dividend on, or a stock split or combination of, outstanding shares of IAC common stock or IAC Class B common stock, or in the event of any merger, consolidation or other reorganization of IAC with another corporation. Upon the conversion of shares of IAC Class B common stock into shares of IAC common stock, those shares of IAC Class B common stock will be retired and will not be subject to reissue. Shares of IAC common stock are not convertible into shares of IAC Class B common stock. Except as described herein, shares of IAC common stock and IAC Class B common stock are identical. The holders of shares of IAC common stock and the holders of shares of IAC Class B common stock are entitled to receive, share for share, such dividends as may be declared by IAC's Board of Directors out of funds legally available therefore. In the event of a liquidation, dissolution, distribution of assets or winding-up of IAC, the holders of shares of IAC common stock and the holders of shares of IAC Class B common stock are entitled to receive, share for share, all the assets of IAC available for distribution to its stockholders, after the rights of the holders of any IAC preferred stock have been satisfied. Reserved Common Shares In connection with equity compensation plans, 19.7 million shares of IAC common stock are reserved at December 31, 2015. Common Stock Repurchases During 2015 and 2013, the Company purchased 3.0 million and 4.5 million shares of IAC common stock for aggregate consideration, on a trade date basis, of $200.0 million and $229.1 million, respectively. During 2014, the Company did not purchase any shares of IAC common stock. On April 30, 2013, IAC's Board of Directors authorized the repurchase of up to 10 million shares of IAC common stock. At December 31, 2015, the Company has approximately 5.6 million shares remaining in its share repurchase authorization.

__________________________________________________________________

(a)

If the effect is dilutive, weighted average common shares outstanding include the incremental shares that would be issued upon the assumed exercise of subsidiary denominated equity, stock options and vesting of restricted stock units ("RSUs"). For the years ended December 31, 2015, 2014 and 2013, 1.5 million, 0.3 million and 0.4 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive.

(b)

Performance-based stock units ("PSUs") are included in the denominator for earnings per share if (i) the applicable performance condition(s) has been met and (ii) the inclusion of the PSUs is dilutive for the respective reporting periods. For each of the years ended December 31, 2015 and 2014 less than 0.1 million PSUs that were probable of vesting were excluded from the calculation of diluted earnings per share because the performance conditions had not been met. For the year ended December 31, 2013, all PSUs that were considered to be probable of vesting were included in the calculation of diluted earnings per share as their performance conditions had been met.

STOCK-BASED COMPENSATION

12 Months Ended

Dec. 31, 2015

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

STOCK-BASED COMPENSATION

IAC currently has two active plans under which awards have been granted. These plans cover stock options to acquire shares of IAC common stock, RSUs, PSUs and restricted stock, as well as provide for the future grant of these and other equity awards. These plans authorize the Company to grant awards to its employees, officers, directors and consultants. At December 31, 2015, there are 4.7 million shares available for grant under the Company's stock-based compensation plans.

The plans were adopted in 2008 and 2013, have a stated term of ten years, and provide that the exercise price of stock options granted will not be less than the market price of the Company's common stock on the grant date. The plans do not specify grant dates or vesting schedules of awards as those determinations have been delegated to the Compensation and Human Resources Committee of IAC's Board of Directors (the "Committee"). Each grant agreement reflects the vesting schedule for that particular grant as determined by the Committee. Broad-based stock option awards issued to date have generally vested in equal annual installments over a four-year period and RSU awards currently outstanding generally vest in two 50% installments over a three and four-year period, in each case, from the grant date. PSU awards currently outstanding generally vest in two installments of up to 50% over a two and three-year period from the date of grant.

The amount of stock-based compensation expense recognized in the consolidated statement of operations is reduced by estimated forfeitures, as the expense recorded is based on awards that are ultimately expected to vest. The forfeiture rate is estimated at the grant date based on historical experience and revised, if necessary, in subsequent periods if actual forfeitures differ from the estimated rate. At December 31, 2015, there is $190.6 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 2.7 years.

The total income tax benefit recognized in the accompanying consolidated statement of operations for the years ended December 31, 2015, 2014 and 2013 related to stock-based compensation is $36.6 million, $22.2 million and $19.3 million, respectively.

Stock Options

Stock options outstanding at December 31, 2015 and changes during the year ended December 31, 2015 are as follows:



	December 31, 2015
	Shares		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value
	(Shares and intrinsic value in thousands)
Outstanding at January 1, 2015	6,520		$	41.19
Granted	2,528		71.17
Exercised	(1,536	)	36.93
Forfeited	(220	)	53.75
Expired	(9	)	35.68
Outstanding at December 31, 2015	7,283		$	52.13	6.9	$	91,329
Options exercisable	3,520		$	37.16	5.1	$	82,073

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between IAC's closing stock price on the last trading day of 2015 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 31, 2015. This amount changes based on the fair market value of IAC's common stock. The total intrinsic value of stock options exercised during the years ended December 31, 2015, 2014 and 2013 is $53.0 million, $63.3 million and $65.6 million, respectively.

The following table summarizes the information about stock options outstanding and exercisable at December 31, 2015:



	Options Outstanding				Options Exercisable
Range of Exercise Prices	Outstanding at December 31, 2015	Weighted- Average Remaining Contractual Life in Years	Weighted- Average Exercise Price		Exercisable at December 31, 2015	Weighted- Average Remaining Contractual Life in Years	Weighted- Average Exercise Price

	7,283	6.9	$	52.13	3,520	5.1	$	37.16

The fair value of stock option awards, with the exception of market-based awards, is estimated on the grant date using the Black-Scholes option pricing model. The Black-Scholes option pricing model incorporates various assumptions, including expected volatility and expected term. During 2015, 2014 and 2013, expected stock price volatilities were estimated based on the Company's historical volatility. The risk-free interest rates are based on U.S. Treasuries with comparable terms as the awards, in effect at the grant date. Expected term is based upon the historical exercise behavior of our employees and the dividend yields are based on IAC's historical dividend payments. The following are the weighted average assumptions used in the Black-Scholes option pricing model:



	Years Ended December 31,
	2015		2014		2013
Expected volatility	28	%	31	%	29	%
Risk-free interest rate	1.6	%	1.5	%	1.0	%
Expected term	5.3 years		4.8 years		6.2 years
Dividend yield	2.0	%	1.5	%	2.0	%

During 2015, the Company granted market-based stock options to certain employees. These awards only vest if the price of IAC common stock exceeds the relevant price threshold for a twenty-day consecutive period and the service requirement is met. The service requirement provides that these awards vest in four equal annual installments beginning on the first anniversary of the grant date. The grant date fair value of each market-based award is estimated using a lattice model that incorporates a Monte Carlo simulation of IAC's stock price. The inputs used to fair value these awards include a weighted average expected volatility of 27%, risk-free interest rate of 2.3% and a 1.8% dividend yield. The expected term of these awards is derived from the output of the option valuation model. Expense is recognized over the longer of the vesting period of each of the four installments or the expected term. The weighted average expected term of these awards is 4 years.

Approximately 2.5 million, 0.7 million and 0.7 million stock options were granted by the Company during the years ended December 31, 2015, 2014 and 2013, respectively. The weighted average fair value of stock options granted during the years ended December 31, 2015, 2014 and 2013 with exercise prices equal to the market prices of IAC's common stock on the date of grant are $15.24, $16.67 and $10.67, respectively. The weighted average exercise price and weighted average fair value of stock options granted during the year ended December 31, 2015 with exercise prices greater than the market value of IAC's common stock on the date of grant are $84.31 and $12.00, respectively. There were no stock options issued during the years ended December 31, 2014 and 2013 with exercise prices greater than the market value of IAC's common stock on the date of grant.

Cash received from stock option exercises and the related tax benefit realized for the years ended December 31, 2015, 2014 and 2013 are: $27.3 million and $25.8 million; $39.1 million and $25.5 million; and $40.7 million and $17.2 million, respectively. In December 2013, the Company's former Chief Executive Officer (the "Executive") became the Chairman of Match Group; in connection with the Executive's compensation arrangement, the Executive exercised 0.5 million stock options, which were settled by the Company for $9.2 million in cash. In January 2014, a portion of the Executive's outstanding IAC stock options were canceled and replaced with equity denominated in a subsidiary of IAC and various subsidiaries of Match Group. The incremental expense associated with this modification was $7.4 million.

Restricted Stock Units and Performance-based Stock Units

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 and with the value of each RSU and PSU equal to the fair value of IAC common stock at the date of grant. Each RSU and PSU grant is subject to service-based vesting, where a specific period of continued employment must pass before an award vests. PSUs also include performance-based vesting, where certain performance targets set at the time of grant must be achieved before an award vests. The Company recognizes expense for all RSUs and PSUs for which vesting is considered probable. For RSU grants, the expense is measured at the grant date as the fair value of IAC common stock and expensed as stock-based compensation over the vesting term. For PSU grants, the expense is measured at the grant date as the fair value of IAC common stock and expensed as stock-based compensation over the vesting term if the performance targets are considered probable of being achieved.

Unvested RSUs and PSUs outstanding at December 31, 2015 and changes during the year ended December 31, 2015 are as follows:



	RSUs				PSUs
	Number of shares		Weighted Average Grant Date Fair Value		Number of shares^(a)		Weighted Average Grant Date Fair Value
	(Shares in thousands)
Unvested at January 1, 2015	750		$	53.61	35		$	71.39
Granted	649		70.11		168		70.88
Vested	(241	)	50.44		—		—
Forfeited	(16	)	71.39		(33	)	71.39
Unvested at December 31, 2015	1,142		$	63.42	170		$	70.89

_______________________________________________________________________________


(a)	Included in the table are PSUs which vest at the end of three years in varying amounts depending upon certain performance conditions. The PSU table above includes these awards at their maximum potential payout.

The weighted average fair value of RSUs and PSUs granted during the years ended December 31, 2015, 2014 and 2013 based on market prices of IAC's common stock on the grant date was $70.27, $68.13 and $42.32, respectively. The total fair value of RSUs and PSUs that vested during the years ended December 31, 2015, 2014 and 2013 was $16.8 million, $20.4 million and $14.5 million, respectively.

Equity Instruments Denominated in the Shares of Certain Subsidiaries

The following description excludes awards denominated in the shares of the Company's publicly-traded subsidiary Match Group. Match Group stock-based awards are issued pursuant to its stock incentive plan.

IAC has granted stock options and stock settled stock appreciation rights, which are denominated in the equity of its subsidiaries, to employees and management of certain subsidiaries. These equity awards vest over a period of years or upon the occurrence of certain prescribed events. The value of the stock options and stock settled stock appreciation rights is tied to the value of the common stock of these subsidiaries. Accordingly, these interests only have value to the extent the relevant business appreciates in value above the initial value utilized to determine the exercise price. These interests can have significant value in the event of significant appreciation. The interests are ultimately settled in IAC common stock with fair market value generally determined by negotiation or arbitration, at various dates through 2024. The expense associated with these equity awards is initially measured at fair value at the grant date and is expensed as stock-based compensation over the vesting term. The aggregate number of IAC common shares that would be required to settle these interests at current estimated fair values, including vested and unvested interests, at December 31, 2015 is 6.4 million shares, which is included in the calculation of diluted earnings per share, if the effect is dilutive. The comparable amount at December 31, 2014 is 5.8 million shares. Following the completion of the Match Group IPO, equity awards that relate to the subsidiaries of Match Group will be settleable, at IAC's election, in shares of IAC common stock or Match Group common stock. To the extent shares of IAC common stock are issued in settlement of these awards, Match Group will reimburse IAC for the cost of those shares by issuing IAC additional shares of Match Group common stock. The aggregate number of IAC common shares at December 31, 2015 included above that would be required to settle Match Group subsidiary equity awards at current estimated fair values, including vested and unvested interests, is 4.1 million shares. The comparable amount at December 31, 2014 is 3.8 million shares.

During the first quarter of 2015, the Company modified certain subsidiary denominated equity awards resulting in a modification charge of $5.8 million of which $3.5 million was recognized in 2015 and $2.3 million will be recognized over the remaining life of the modified awards. During the third quarter of 2015, the Company modified certain subsidiary denominated vested equity awards and recognized a modification charge of $6.8 million. During the fourth quarter of 2015, the Company repurchased certain subsidiary denominated vested equity awards in exchange for $23.4 million in cash and fully vested modified equity awards and recognized a modification charge of $7.7 million. These modification charges are included in stock-based compensation for the year ended December 31, 2015.

During 2014, the Company granted to a non-employee equity in a certain subsidiary of the company that is marked to market each reporting period. The award has a vesting multiple times a year and is fully vested in 2017. At December 31, 2015, the total fair value of this award, at current estimated fair value including vested and unvested interests, is $19.6 million.

SEGMENT INFORMATION

Segment Reporting [Abstract]

SEGMENT INFORMATION

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

(a)

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


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

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

Prior to the fourth quarter of 2015, Search & Applications was a reportable segment consisting of one operating segment and one reporting unit. In the fourth quarter of 2015, Search &Applications was split into three new operating segments and reportable units: Publishing, Applications and PriceRunner (included in the Other segment). The goodwill of Search & Applications was allocated to these three reporting units based upon their relative fair values as of October 1, 2015. It is not possible to reflect this allocation on a retrospective basis because of acquisitions and dispositions during the three years in the period ended December 31, 2015. See Note 1 for additional information on the realignment of IAC's reportable segments and Note 4 for additional information on goodwill.

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS

The Company leases land, office space, data center facilities and equipment used in connection with its operations under various operating leases, many of which contain escalation clauses. The Company is also committed to pay a portion of the related operating expenses under a data center lease agreement. These operating expenses are not included in the table below.

Future minimum payments under operating lease agreements are as follows:



Years Ending December 31,	(In thousands)
2016	$	33,073
2017	32,539
2018	28,252
2019	22,352
2020	15,547
Thereafter	200,554
Total	$	332,317

Expenses charged to operations under these agreements are $39.4 million, $41.2 million and $36.7 million for the years ended December 31, 2015, 2014 and 2013, respectively.

The Company's most significant operating lease is a seventy-seven year land lease for IAC's headquarters building in New York City and approximates 53% of the future minimum payments due under all operating lease agreements in the table above.

The Company also has funding commitments that could potentially require its performance in the event of demands by third parties or contingent events as follows:



	Amount of Commitment Expiration Per Period
	Less Than 1 Year		1-3 Years		3-5 Years		More Than 5 Years		Total Amounts Committed
	(In thousands)

CONTINGENCIES	12 Months Ended
CONTINGENCIES	Dec. 31, 2015
Commitments and Contingencies Disclosure [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 for additional information related to income tax contingencies.

- Definition

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

BENEFIT PLANS	12 Months Ended
BENEFIT PLANS	Dec. 31, 2015
Compensation and Retirement Disclosure [Abstract]
BENEFIT PLANS	BENEFIT PLANS IAC has a retirement savings plan in the United States that qualifies under Section 401(k) of the Internal Revenue Code. Participating employees may contribute up to 50% of their pre-tax earnings, but not more than statutory limits. IAC contributes fifty cents for each dollar a participant contributes in this plan, with a maximum contribution of 3% of a participant's eligible earnings. Matching contributions for the plan for the years ended December 31, 2015, 2014 and 2013 are $9.1 million, $7.5 million and $6.5 million, respectively. Matching contributions are invested in the same manner as each participant's voluntary contributions in the investment options provided under the plan. An investment option in the plan is IAC common stock, but neither participant nor matching contributions are required to be invested in IAC common stock. The increase in matching contributions in 2015 is due primarily to an increase in participation in the plan due to increased headcount and recent acquisitions. IAC also has or participates in various benefit plans, principally defined contribution plans, for its international employees. IAC's contributions for these plans for the years ended December 31, 2015, 2014 and 2013 are $2.5 million, $2.5 million and $2.6 million, respectively.

(a)

During the fourth quarter of 2015, certain expenses were reclassified between cost of revenue and selling and marketing expense. Accordingly, cost of revenue presented above for periods prior to the fourth quarter of 2015 differs from the amounts reflected in the Company’s quarterly reports on Form 10-Q for the first, second and third quarters of 2015 and 2014 and for the fourth quarter of 2014 reflected in the Company's annual report on Form 10-K.


(b)	The fourth quarter of 2015 includes after-tax impairment charges related to indefinite-lived intangible assets and goodwill of $55.3 million and $14.1 million, respectively.


(c)	The second quarter of 2014 includes an after-tax other-than-temporary impairment charge of $63.6 million related to the write-down of certain cost method investments to fair value.


(d)	(Loss) earnings from discontinued operations, net of tax, in the third quarter of 2014 includes the release of tax reserves as a result of the expiration of the statutes of limitations for federal income taxes for the years 2001 through 2009.


(e)	Quarterly per share amounts may not add to the related annual per share amount because of differences in the average common shares outstanding during each period.

⁽¹⁾	Additions to the allowance for doubtful accounts are charged to expense. Additions to the revenue reserves are charged against revenue.


⁽²⁾	Amount is primarily related to the release of a valuation allowance on the other-than-temporary impairment charges for certain cost method investments, partially offset by an increase in federal, foreign and state net operating and capital losses.


⁽³⁾	Amount is primarily related to a net reduction in unbenefited unrealized losses on available-for-sale marketable equity securities included in accumulated other comprehensive income and currency translation adjustments on foreign net operating losses.


⁽⁴⁾	Write-off of fully reserved accounts receivable.


⁽⁵⁾	Amount is primarily related to other-than-temporary impairment charges for certain cost method investments and an increase in federal net operating losses, foreign tax credits, and state tax credits.


⁽⁶⁾	Amount is primarily related to unbenefited unrealized losses on long-term marketable equity securities included in accumulated other comprehensive income, partially offset by currency translation adjustments on foreign net operating losses.


⁽⁷⁾	Additions to the magazine publishing allowance for newsstand returns are related to magazine publishing at Newsweek and were charged against revenue. The Newsweek print business was transitioned to a digital only publication in December 2012 and was subsequently sold in August 2013.


⁽⁸⁾	Amount represents returns of magazines at Newsweek. The Newsweek print business was transitioned to a digital only publication in December 2012 and was subsequently sold in August 2013.


⁽⁹⁾	Amount is primarily related to foreign and federal net operating losses, partially offset by a decrease in deferred tax assets for investments in subsidiaries and available-for-sale securities.


⁽¹⁰⁾	Amount is primary related to the release of a valuation allowance on unrealized gains on long-term marketable equity securities included in accumulated other comprehensive income.
