COMPENSATION DISCUSSION AND ANALYSIS

Philosophy and Objectives

Our executive officers whose compensation is discussed in this compensation discussion and analysis (the “CD&A”) and who we refer to as our named executive officers in this CD&A (the “NEOs”) are:

·                  Barry Diller, Chairman and Senior Executive;

·                  Victor Kaufman, Vice Chairman;

·                  Joey Levin, Chief Executive Officer commencing June 2015;

·                  Gregg Winiarski, Executive Vice President and General Counsel; and

·                  Jeffrey Kip, Chief Financial Officer through June 2015.

Our executive officer compensation program is designed to increase long-term stockholder value by attracting, retaining, motivating and rewarding leaders with the competence, character, experience and ambition necessary to enable the Company to meet its growth objectives.

Though IAC is a publicly traded company, we attempt to foster an entrepreneurial culture, and attract and retain senior executives with entrepreneurial backgrounds, attitudes and aspirations. Accordingly, when attempting to recruit and retain our executive officers, as well as other executives who may become executive officers at a later time, we compete not only with other public companies, but also with earlier stage companies, companies funded by private equity and venture capital firms and professional firms. We structure our compensation program so that we can compete in this varied marketplace for talent, with an emphasis on variable, contingent compensation and long-term equity ownership.

While we consider market data in establishing broad compensation programs and practices and may periodically benchmark the compensation associated with particular executive positions, we do not definitively rely on competitive survey data or any benchmarking information in establishing executive compensation. The Company makes decisions based on a host of factors particular to a given executive’s situation, including its firsthand experience with the competition for recruiting executives and its understanding of the current environment, and believes that over-reliance on survey data, or a benchmarking approach, is too rigid and stale for the dynamic and fast changing marketplace for talent in which we compete.

Similarly, we believe that arithmetic approaches to measuring and rewarding short-term performance often fail to adequately take into account the multiple factors that contribute to success at the individual and business level. In any given period, the Company may have multiple objectives, and these objectives, and their relative importance, often change as the competitive and strategic landscapes shift. Accordingly, we have historically avoided the use of strict formulas in our annual bonus program, believing that they often over-compensate or under-compensate a given performance level. We instead rely

primarily on an approach that, while based on clear objectives, is not formulaic and allows for the exercise of discretion in setting final bonus amounts.

In addition, we are of the view that long-term incentive compensation in the form of equity awards aligns the interests of executives and long-term shareholders, and to further this important goal, equity awards play a prominent role in our overall compensation program. We have used non-qualified stock options as the predominant equity incentive vehicle for our executives for many years.   We use this equity incentive instrument primarily for the sake of simplicity given that the value from stock option awards is directly dependent on appreciation in the Company’s stock price and therefore provides an objectively measurable goal, and a belief that it would, in general, make the Company more competitive in recruiting talented executives and employees. From time to time, however, executives have been awarded restricted stock units in addition to, or in lieu of, stock option awards, depending on the individual circumstances, and in 2015 one of our executives was awarded restricted stock units as described below.

We believe that the Company’s executive officer compensation program puts the substantial majority of compensation at risk, rewards both individual and corporate performance in a targeted fashion, pays amounts appropriate to attract and retain those key individuals necessary to grow the Company and aligns the interests of our key executives with the interests of our stockholders. We continuously evaluate our program and make changes as we deem appropriate.

Roles and Responsibilities

The Compensation and Human Resources Committee of the Company’s Board of Directors (for purposes of this CD&A, the “Committee”) has primary responsibility for establishing the compensation of the Company’s executive officers. All compensation decisions referred to throughout this CD&A have been made by the Committee, based (in part) on recommendations from Mr. Diller and Mr. Levin (as described below). The Committee currently consists of Mr. Rosenblatt and Ms. Hammer.

The executive officers participate in structuring Company-wide compensation programs and in establishing appropriate bonus and equity pools. In early 2016, Messrs. Diller and Levin met with the Committee and discussed their views of corporate and individual executive officer performance for 2015 for Messrs. Kaufman and Winiarski, and their recommendations for annual bonuses for those executive officers. Mr. Diller also discussed Mr. Levin’s performance, and his views on his own performance, with the Committee. Following these discussions, the Committee met in executive sessions to discuss these recommendations.  After consideration of these recommendations, the Committee ultimately determined the annual bonus amount for each executive officer.

In establishing a given executive officer’s compensation package, each individual component is evaluated independently and in relation to the package as a whole. Prior earning histories and outstanding long-term compensation arrangements are also reviewed and taken into account. However, we do not believe in any formulaic relationship or targeted allocation between these elements. Instead, each individual’s situation is evaluated on a case-by-case basis each year, considering the variety of relevant factors at that time.

From time to time, the Committee has solicited the advice of consulting firms and engaged legal counsel. Except as noted below, no such consulting firms or legal counsel were engaged during 2015.

In addition, from time to time, the Company may solicit survey or peer compensation data from various consulting firms. In 2015, the Company engaged Mercer (US) Inc. to provide comparative market data in connection with the Company’s own analysis of its equity compensation practices, but neither Mercer nor any other compensation consultant engaged by the Company had any role in determining or recommending the amount or form of executive compensation for 2015.

In 2015, the Committee engaged Compensation Advisory Partners LLC (“CAP”) to assist the Committee in its consideration of long-term incentive awards for Mr. Diller and Mr. Levin, as discussed further below under the heading “2015 Equity Awards.”

Compensation Elements

Our compensation packages for executive officers primarily consist of salary, annual bonuses, IAC equity awards and, in certain instances, perquisites and other benefits.

Salary

We typically negotiate a new executive officer’s starting salary upon arrival, based on the executive’s prior compensation history, prior compensation levels for the particular position within the Company, the Company’s New York City location, salary levels of other executives within the Company and salary levels available to the individual in alternative opportunities. Salaries can increase based on a number of factors, including the assumption of additional responsibilities and other factors which demonstrate an executive’s increased value to the Company. No executive officer’s salary was adjusted during 2015.

Annual Bonuses

General.  We establish bonus levels through a two-pronged process. First, at the beginning of each year, the Committee sets performance objectives, which historically have been tied to the achievement of EBITDA (as defined below), revenue or share price performance targets during the forthcoming year, and maximum bonus amounts. In general, these performance targets are minimum acceptable performance conditions, but with respect to which there is substantial uncertainty when we establish them. The establishment of performance targets and maximum bonus amounts is undertaken primarily to satisfy the requirements of Section 162(m) of the Internal Revenue Code, as amended. Satisfaction of one or more of the performance targets established by the Committee allows for the payment of bonuses that will be deductible by the Company for federal income tax purposes, should any bonuses be awarded to the Company’s named executive officers.  However, satisfaction of the applicable performance targets does not obligate the Committee to approve any specific bonus amount for any executive officer, and the Committee has historically reduced the maximum bonus amount based on a discretionary assessment of Company and, to a lesser extent, individual performance. In making its determinations regarding individual annual bonus amounts, the Committee considers a variety of factors, such as growth in profitability or achievement of strategic objectives by the Company, and an individual’s performance and contribution to the Company. The Committee does not quantify the weight given to any specific element or otherwise follow a formulaic calculation. Rather, the Committee engages in an overall assessment of appropriate bonus levels based on a subjective interpretation of all relevant criteria. This process is designed to permit the Company to deduct the bonus compensation paid to executives for income tax purposes.

The definition of EBITDA used for establishing Section 162(m) performance objectives comes from IAC’s 2013 Stock and Annual Incentive Plan, and is as follows: “EBITDA” means for any period, operating profit (loss) plus, if applicable: (i) depreciation, (ii)  amortization and impairment of intangibles, (iii) goodwill impairment, (iv) non-cash compensation expense, (v) restructuring charges, (vi) non cash write-downs of assets, (vii) charges relating to disposal of lines of business, (viii) litigation settlement amounts and (ix) costs incurred for proposed and completed acquisitions.

2015 Bonuses.  For 2015, the Committee predicated the payment of bonuses to executive officers on attaining: (i) EBITDA in any of the four consecutive calendar quarters beginning with the first quarter of 2015 at least equal to EBITDA in the corresponding calendar quarter twelve months before, (ii) revenue in any of the four consecutive calendar quarters beginning with the first quarter of 2015 at least equal to revenue in the corresponding calendar quarter twelve months before or (iii) share price growth of at least 5% over $63.83 (the closing price of the Company’s common stock on December 31, 2014) on any 20 trading days during the period beginning on January 1, 2015 through December 31, 2015. Two of the targets were met.  After concluding that the threshold performance targets for the payment of bonuses had been achieved, the Committee then exercised its right to reduce bonus amounts for each individual executive officer from the maximum level established. In setting actual bonus levels, the Committee considered a variety of factors, including:

·Successful Completion of Match Group IPO.  In November 2015, Match Group successfully completed its initial public offering.  The Company believes that this transaction has positioned both IAC and Match Group to enhance the ability of shareholders of both companies to realize value over the long term.  At December 31, 2015, the Company’s ownership interest and voting interest in Match Group were 84.6% and 98.2%, respectively;

·Successful Completion of Other Transactions.  The Company amended and extended its services agreement with Google and continued its disciplined approach to acquisitions, including the acquisition of PlentyOfFish;

·Capitalization and Cash Position.  The Company repatriated a significant amount of cash to stockholders during 2015 by way of share repurchases and quarterly cash dividends. In addition, during 2015: (i) the Company amended and extended its $300 million revolving credit facility, and (ii) Match Group entered into a credit agreement providing for a $500 million credit facility and an $800 million term loan and exchanged $445.3 million of IAC’s 4.75% senior notes for $445.2 of Match Group 6.75% senior notes, providing for appropriate capital structures for both entities as they continue to invest in their businesses and identify new opportunities for expansion; and

·Revenue and Adjusted EBITDA Results.  Revenue increased modestly over the prior year, reflecting growth in The Match Group, HomeAdvisor and Video segments. Adjusted EBITDA declined 11% for the year, reflecting increased selling and marketing expenses, as well as lower revenue in certain segments.

While the factors noted above were the primary ones considered in setting bonus award amounts, the Committee also considered each executive’s role and responsibilities, the relative contributions made by each executive officer during the year and the relative size of the bonuses paid to the other executive officers.  Notwithstanding many significant achievements during the year, Mr. Diller did not receive a bonus for 2015 due to the Company’s disappointing financial performance.  With respect to bonuses for other executives, the Committee considered the following: (i)  with respect to Mr. Levin, his new role as Chief Executive Officer of the Company, including his focus on managing the day-to-day business operations of the Company, as well as his participation in the major initiatives undertaken during 2015 and his role in developing strategic initiatives for the Company, (ii) with respect to Mr. Kaufman, his participation in strategic oversight of the Company, and (iii) with respect to Mr. Winiarski, his role in managing the successful completion of the Match Group initial public offering and related debt transactions, as well as the PlentyOfFish acquisition.

As noted above, in setting individual bonus amounts, the Committee did not quantify the weight assigned to any specific factor, nor apply a formulaic calculation. In setting bonus amounts, the Committee generally considered the Company’s overall performance, the amount of bonus for each named executive relative to other Company executives and the recommendations of the Chairman and Senior Executive and the Chief Executive Officer. In addition, the Committee considered achievements in 2015 as compared to achievements and bonus levels in prior years.

Executive officer bonuses tend to be highly variable from year-to-year depending on the performance of the Company and, in certain circumstances, individual performance. Accordingly, we believe our executive officer bonus program provides strong incentives to reach the Company’s annual goals.

Long-Term Incentives

General.  Due to our entrepreneurial philosophy, we believe that providing a meaningful equity stake in our business is essential to create compensation opportunities that can compete, on a risk-adjusted basis, with entrepreneurial employment alternatives. In addition, we believe that ownership shapes behavior, and that by providing compensation in the form of equity awards, we align executive incentives with stockholder interests in a manner that we believe drives superior performance over time.

While there is currently no formal stock ownership or holding requirement for executive officers, our executive officers generally have historically held a significant portion of their stock awards (net of tax withholdings) well beyond the relevant vesting dates.

In establishing equity awards for an executive for any given period, the amount of outstanding unvested and/or unexercised equity awards, as well as previously earned or exercised awards, is reviewed and evaluated on an individual-by-individual basis. In setting particular award levels, the predominant considerations are providing the executive with effective retention incentives, appropriate reward for past performance, incentives for strong future performance and competitive conditions. The annual corporate performance factors relevant to setting bonus amounts, while taken into account, are generally less relevant in determining the type and level of equity awards, as the awards tend to be more forward looking, and are a longer-term retention and reward instrument relative to our annual bonuses.

The Company’s usual practice is to schedule the Committee meetings at which awards are to be made in advance, without regard to the timing of the release of earnings or other material information.

2015 Equity Awards.  In February 2015, the Committee granted 100,000 stock options to each of Messrs. Kip and Winiarski. The options vest 25% a year, on the first four anniversaries of the grant date, and have an exercise price equal to the closing price of the Company’s common stock on the grant date.  Also in February 2015, Mr. Kaufman received a restricted stock unit award with a dollar value of $350,000 in accordance with the terms of his employment agreement. The restricted stock units will vest in three equal installments on each of the first three anniversaries of the grant date.

In February and June 2015, to assist the Committee as it considered new equity awards for Mr. Diller and Mr. Levin, respectively, the Company engaged CAP to evaluate various long-term incentive alternatives for each of those executives and, in the case of Mr. Diller, make recommendations to the Committee.

In March 2015, the Committee awarded Mr. Diller 1,000,000 stock options which will vest 25% a year on the first four anniversaries of the grant date. One half of the options have an exercise price equal to, and the other half of the options have an exercise price equal to 125% of, the closing price of the Company’s common stock on the trading day immediately preceding the grant date.

In making this grant to Mr. Diller, the Committee considered that the last time Mr. Diller received an equity award was in 2011, and prior to that was in 2005. The Committee also noted that the options granted in 2005 were set to expire in June 2015 and that the last tranche of the options granted in 2011 fully vested in February 2015. As a result, the Committee determined it was in the best interest of the Company to provide Mr. Diller an additional long-term incentive award.  In finalizing the structure of the award, the Committee took into account a variety of factors, including:

·                  competitive pay and performance data among comparator groups of companies;

·                  the vesting and expiration schedules of Mr. Diller’s existing long-term incentive arrangements;

·                  the nature of Mr. Diller’s outstanding long-term incentive arrangements;

·                  the incentive to create additional shareholder value inherent in the premium option pricing component of the new package;

·                  the Committee’s substantial desire to retain Mr. Diller’s services for the long-term; and

·                  the Company’s history of granting Mr. Diller equity awards once every few years (and the Committee’s intention to remain consistent with that approach).

The Committee also considered the value realized by Mr. Diller from his exercise of stock options over the years and the intrinsic value of his currently outstanding options. They took note that Mr. Diller had generally exercised options after holding them for substantial periods of time after grant, and as a result, the Committee considered the realization of value by Mr. Diller to be primarily a function of both personal investment decisions by him and the timing of the relevant option expiration dates, and not compensation for the periods in which it would be realized.

On June 24, 2015, Mr. Levin was appointed as the Company’s Chief Executive Officer.  In his former role as Chief Executive Officer of IAC Search, a portion of his long-term incentives were tied to that business.  When the Company asked Mr. Levin to become Chief Executive Officer, the Committee desired to have a compensation structure for him that provided incentives directly aligned with the performance of the Company as a whole.  In June 2015, the Committee awarded Mr. Levin 400,000 stock options which will vest 25% a year, on the first four anniversaries of the grant date, and have an exercise price equal to the closing price of the Company’s common stock on the grant date, with 50% of these options becoming exercisable only if the closing pricevote per share, of the Company’s common stock during any 20 consecutive days equals or exceeds 150% of the closing price of the Company’s common stock on the grant date.  In connection with this new award, Mr. Levin surrendered to the Company equity awards previously granted to him  that were tied solely to the IAC Search business.  In finalizing the structure of the award, the Committee took into account a variety of factors, including many of those considered in connection with Mr. Diller’s award, as discussed above.

We believe these awards provide meaningful retention and performance incentives for our executive officers.

2016 Equity Awards.  In February 2016, the Committee granted 200,000 stock options to Mr. Levin and 100,000 stock options to Mr. Winiarski.  The options vest 25% a year, on the first four anniversaries of the grant date, and have an exercise price equal to the closing price of the Company’s common stock on the grant date.  Also in February 2016, Mr. Levin received 100,000 restricted stock units, vesting in one lump sum installment on the third anniversary of the grant date, and Mr. Kaufman received a restricted stock unit award with a dollar value of $350,000 in accordance with the terms of his employment agreement, vesting in thirds on the first three anniversaries of the grant date.

Change of Control

The Company’s equity awards for senior executives generally include a so-called “double-trigger” change of control provision, which provides for the acceleration of the vesting of outstanding equity awards in connection with a change of control only when an award recipient suffers an involuntary termination of employment within two years of such change of control. The Committee believes that providing for the acceleration of the vesting of equity awards after an involuntary termination will assist in the retention of our executives through a change of control transaction. For purposes of this discussion and the discussion below under the heading “Severance,” we use the term “involuntary termination” to mean both a termination by the Company without “cause” and a resignation by the executive for “good reason” or similar construct.

Severance

We generally provide executive officers with some amount of salary continuation and some amount of accelerated vesting of equity awards in the event of an involuntary termination of employment. Because we tend to promote our executive officers from within, after competence and commitment have generally been established, we believe that the likelihood of the vesting of equity awards being accelerated is typically low, and yet we believe that through providing this benefit we increase the retentive effect of our equity program, which serves as our most important retention incentive. The Company generally does not provide for the acceleration of the vesting of equity awards in the event an executive voluntarily resigns from the Company.

Other Compensation

General.  We provide Mr. Diller with various non-cash benefits as part of his overall compensation program. Under certain limited circumstances, other executive officers have also received non-cash benefits. The value of these benefits is calculated under appropriate rules and is taken into account as a component of compensation when establishing overall compensation levels. The value of all non-cash benefits is reported under the “All Other Compensation” column in the Summary Compensation Table on page 14 pursuant to applicable rules. Our executive officers do not participate in any deferred compensation or retirement programs other than the Company’s 401(k) plan. During 2015, we did not (and generally do not) gross-up any benefits provided to any executive officer. Other than those described specifically below, our executive officers do not partake in any benefit programs, or receive any significant perquisites, distinct from the Company’s other employees.

Mr. Diller.  Pursuant to Company policy, Mr. Diller is required to travel, both for business and personal purposes, on corporate aircraft. In addition to serving general security interests, this means of travel permits him to travel non-stop and without delay, to remain in contact with the Company while he is traveling, to change his plans quickly in the event Company business requires and to conduct confidential Company business while flying, be it telephonically, by e-mail or in person. These interests are similarly furthered on both business and personal flights, as Mr. Diller typically provides his services to the Company while traveling in either case. Nonetheless, the incremental cost to the Company of his travel for personal purposes is reflected as compensation to Mr. Diller from the Company, and is taken into account in establishing his overall compensation package. For certain personal use of Company-owned aircraft, Mr. Diller reimburses the Company at the maximum rate allowable under applicable rules of the Federal Aviation Administration.

Additionally, the Company provides Mr. Diller with a cash car allowance, as well as providing access to certain automobiles for business and personal use. We also provide certain Company-owned office space and IT equipment for use by certain individuals who work for Mr. Diller personally. These uses are valued by the Company at their incremental cost to the Company or, in the case of the use of office space (where there is no discernible incremental cost), at the cost used for internal allocations of office space for corporate purposes.

Mr. Kaufman.  Mr. Kaufman is entitled to use corporate aircraft for a certain amount of personal travel annually. However, Mr. Kaufman reimburses the Company for the Company’s incremental cost of such travel and therefore the value of such travel is not treated as compensation to Mr. Kaufman. Typically, Mr. Kaufman’s spouse accompanies him on personal and business flights at no incremental cost to the Company.

Mr. Levin.  Pursuant to Company policy, Mr. Levin is encouraged to travel, both for business and personal purposes, on corporate aircraft for the same reasons as set forth above for Mr. Diller. The incremental cost to the Company of his travel for personal purposes is reflected as compensation to Mr. Levin from the Company, and is taken into account in establishing his overall compensation package.

Tax Deductibility

Whenever possible, we endeavor to structure our compensation program so that the compensation we pay is deductible by the Company for federal income tax purposes. Because of the use of performance conditions in connection with our equity awards and annual bonuses, and the fact that no salaries are in excess of $1 million, these three components are generally deductible by the Company. However, under applicable IRS rules, the personal use of corporate aircraft leads to a disallowance of the deduction of certain airplane and related costs.

EXECUTIVE COMPENSATION

Overview

The Executive Compensation section sets forth certain information regarding total compensation earned by our named executives in 2015, as well as equity awards made to our named executives in 2015, equity awards held by our named executives on December 31, 2015 and the dollar value realized by our named executives upon the vesting and exercise of equity awards during 2015.

Summary Compensation Table

(1)Reflects the dollar value of RSU awards, calculated by multiplying the closing market price of IAC common stock on the grant date by the number of RSUs awarded.

(2)In 2015, Messrs. Diller, Levin, Kip and Winiarski were granted stock option awards with vesting tied to continued service and Mr. Levin was granted a performance stock option award with vesting tied to continued service and exercisability tied to the satisfaction of certain performance-based conditions related to the Company’s stock price.  Accordingly, for Messrs. Diller, Kip and Winiarski, these amounts represent the grant date fair value of their stock option awards using the Black-Scholes option pricing model. And for Mr. Levin, $3,980,000 of this amount represents the grant date fair value of stock option awards using the Black-Scholes option pricing model and $4,086,000 of this amount represents the grant date fair value of the performance stock option award using a lattice model that incorporates a Monte Carlo simulation of the Company’s stock price. For details regarding the assumptions used to calculate these amounts in 2015, see footnotes 4 and 7 to the Grants of Plan-Based Awards in 2015 table on page 16.

(3)Additional information regarding all other compensation amounts for each named executive in 2015 is as follows:

(a)Pursuant to the Company’s Airplane Travel Policy, Mr. Diller is required to travel by Company-owned or chartered aircraft for both business and personal purposes and Mr. Levin is encouraged to use Company aircraft for business and personal travel when doing so would serve the interests of the Company.  See the discussion regarding airplane travel under Compensation Discussion and Analysis on page 13. We calculate the incremental cost to the Company for personal use of Company aircraft based on the average variable operating costs to the Company. Variable operating costs include fuel, certain maintenance costs, navigation fees, on-board catering, landing fees, crew travel expenses and other miscellaneous variable costs. The total annual variable costs are divided by the annual number of miles the Company aircraft flew to derive an average variable cost per mile. This average variable cost per mile is then multiplied by the miles flown for personal use. Incremental costs do not include fixed costs that do not change based on usage, such as pilots’ salaries, the purchase costs of Company-owned aircraft, insurance, scheduled maintenance and non-trip related hangar expenses. Messrs. Diller and Levin occasionally had family members or other guests accompany them on business and personal trips. While travel by family members or other guests does not result in any incremental cost to the Company, such travel does result in the imputation of taxable income to Messrs. Diller and Levin, the amount of which is calculated in accordance with applicable IRS regulations.

(b)Represents the total amount of other benefits provided to Mr. Diller, none of which individually exceeded 10% of the total value of all perquisites and personal benefits. The total amount of other benefits provided reflects: (i) lease payments, parking, fuel, maintenance and other costs associated with Mr. Diller’s personal use of an automobile leased and maintained by IAC and a cash car allowance, (ii) an allocation (based on square footage) of costs for the use of IAC office space by certain individuals who work for Mr. Diller personally, (iii) an allocation (based on the number of personal computers and communication devices supported by IAC) of costs relating to the use by such individuals of the Company’s IT technical support and certain communications equipment and (iv) costs incurred for Mr. Diller’s personal use of other car services.

(4)In connection with the grant of IAC stock options to Mr. Levin at the time he was appointed Chief Executive Officer of IAC in June 2015, Mr. Levin surrendered equity awards tied solely to the value of IAC’s Search business.

Grants of Plan-Based Awards in 2015

The table below provides information regarding all stock options and RSUs granted to our named executives in 2015.

(1)                                 For information on the treatment of stock options and RSUs upon a termination of employment (including certain terminations during specified periods following a change in control of IAC), see the discussion under Estimated Potential Payments Upon Termination or Change in Control of IAC beginning on page 19.

(2)                                 These stock options vested/vest in four equal installments on the first four anniversaries of the applicable grant date, subject to continued employment.

(3)                                 The exercise price is equal to the fair market value per share (as defined in the applicable stock and annual incentive plan) of IAC common stock on the grant date.

(4)                                 Reflects the grant date fair value of stock option awards using the Black-Scholes option pricing model. The Black-Scholes option pricing model incorporates various assumptions, including expected volatility (based on the historical volatility of IAC common stock), risk-free interest rates (based on U.S. Treasury yields for notes with terms comparable to those of the stock options, in effect at the grant date), expected term (based on the historical exercise behavior of our employees) and dividend yield (based on IAC’s historical dividend payments). The assumptions used to calculate the amounts in the table above for stock option awards granted to our named executive are as follows:

(5)                                 The exercise price is equal to 125% of the fair market value per share (as defined in the applicable stock and annual incentive plan) of IAC common stock on the grant date.

(6)                                 These stock options vest in four equal installments on the first four anniversaries of the grant date, subject to continued employment, and become exercisable if the closing price per share of the Company’s common stock during any 20 consecutive trading day period equals or exceeds $115.89 (a 50% increase to the closing price of the Company’s common stock on the grant date) at any time during the period during which the stock options are outstanding.

(7)                                 Reflects the grant date fair value of the performance stock option award granted to Mr. Levin using a lattice model that incorporates a Monte Carlo simulation of IAC’s stock price. The assumptions used to calculate the amount in the table above for this award are as follows: weighted average expected volatility (27)%, risk-free interest rate (2.3%), and dividend yield (1.8%). The expected term of this award (4 years) is derived from the output of the valuation model.

(8)                                 These RSUs vested/vest in three equal installments on the first three anniversaries of the grant date, subject to continued employment.

(9)                                 Reflects the dollar value of RSU awards, calculated by multiplying the closing market price of IAC common stock on the grant date by the number of RSUs awarded.

Outstanding Equity Awards at 2015 Fiscal Year-End

The table below provides information regarding equity awards held by our named executives on December 31, 2015. The market value of all RSU awards is based on the closing price of IAC common stock on December 31, 2015 ($60.05).

(1)                                 The table below provides the following information regarding RSUs held by our named executives on December 31, 2015: (i) the grant date of each award, (ii) the number of RSUs outstanding on December 31, 2015, (iii) the market value of RSUs outstanding on December 31, 2015, (iv) the vesting schedule for each award and (v) the total number of RSUs that vested/are scheduled to vest in each of the fiscal years ending December 31, 2016, 2017, 2018 and 2019.

(2)                                 These stock options vested/vest in four equal installments on the first four anniversaries of the applicable grant date, subject to continued employment.

(3)                                 The last installment of these stock options (with each installment representing one-third of the award) vested on February 2, 2016.

(4)                                 The three remaining installments of these stock options (with each installment representing 25% of the award) vest on July 29, 2016, 2017 and 2018, subject to continued employment.

(5)                                 Consists of: (i) 200,000 stock options that vest in four equal installments on the first four anniversaries of the grant date, subject to continued employment, and (ii) 200,000 performance stock options that vest on the first four anniversaries of the grant date, subject to continued employment, and become exercisable if the closing price per share of the Company’s common stock during any 20 consecutive trading day period equals or exceeds $115.89 (a 50% increase to the closing price of the Company’s common stock on the grant date) at any time during the period during which the stock options are outstanding.

(6)                                 The last installment of these stock options (with each installment representing one-third of the award) vested on March 14, 2016.

(7)                                 The two remaining installments of these stock options (with each installment representing 25% of the initial award) vested/vest in equal installments on May 3, 2016 and 2017, subject to continued employment.

(8)                                 The three remaining installments of these stock options (with each installment representing 25% of the initial award) vested/vest in equal installments on February 11, 2016, 2017 and 2018, subject to continued employment.

(9)                                 The last installment of these stock options (with each installment representing 25% of the award) vested on February 2, 2016.

2015 Option Exercises and Stock Vested

The table below provides information regarding the number of shares acquired by our named executives upon the exercise of stock options and the vesting of RSU awards in 2015 and the related value realized, excluding the effect of any applicable taxes. The dollar value realized upon the exercise of stock options represents the difference between: (i)(A) in the case of simultaneous exercise and sale transactions, the sale price of the shares acquired upon exercise, or (B) in the case of Mr. Diller’s exercise only, the closing price of IAC common stock on the exercise date given the fact that no simultaneous sale occurred, and (ii) the exercise price of the stock options, multiplied by the number of stock options exercised.  The dollar value realized upon the vesting of RSUs represents the closing price of IAC common stock on the vesting date, multiplied by the number of RSUs so vesting.

(1)                                 Mr. Diller also exercised HSN, Inc. and Tree.com, Inc. stock options in 2015, in connection with which he received gross proceeds of $11,996,840 and $5,132,875, respectively. In both cases, these amounts represent the difference between the exercise price of the applicable stock options and the fair market value per share (as defined in the applicable stock and annual incentive plan) of the applicable common stock underlying such stock options at the time of exercise.

Mr. Diller received these stock options as a result of spin-off transactions completed by the Company in August 2008. The value realized upon the exercise of these non-IAC stock options by Mr. Diller is treated for tax purposes as compensation payable to him in his capacity as Chairman and Senior Executive of the Company.

(2)                                 In connection with the exercise of these stock options, the Company withheld 395,654 shares of IAC common stock to cover the payment of the exercise price and 173,369 shares of IAC common stock to cover the payment of taxes due in connection with the exercise, which resulted in the issuance of 136,711 shares of IAC common stock to Mr. Diller.

Estimated Potential Payments Upon Termination or Change in Control of IAC

Certain of our employment agreements, equity award agreements and/or omnibus stock and annual incentive plans entitle our named executives to continued base salary payments, the acceleration of the vesting of equity awards and/or extended post-termination exercise periods for stock options upon certain terminations of employment (including certain terminations during specified periods following a change in control of IAC). These arrangements are described below as they would have applied to each named executive on December 31, 2015.

Certain amounts that would have become payable to our named executives upon the events described above (as and if applicable), assuming that the relevant event occurred on December 31, 2015, are described and quantified in the table below. These amounts, which exclude the effect of any applicable taxes, are based on the named executive’s base salary and the number of stock options and/or RSUs outstanding on December 31, 2015 and the closing price of IAC common stock ($60.05) on December 31, 2015. In addition to these amounts, certain other amounts and benefits generally payable and made available to other Company employees upon a termination of employment, including payments for accrued vacation time and outplacement services, will generally be payable to named executives.

Messrs. Diller and Levin

No payments would have been made to Messrs. Diller and Levin pursuant to any agreement between the Company and these named executives upon a termination without cause or due to death or disability or a resignation for good reason on December 31, 2015.  In addition, no payments would have been made Messrs. Diller and Levin pursuant to any agreement between the Company and these named executives upon a change in control of IAC on December 31, 2015. Lastly, upon a termination without cause or resignation for good reason following a change in control of IAC on December 31, 2015, in accordance with the applicable omnibus stock and incentive plan and the related award agreements, the vesting of all then

outstanding and unvested stock options and/or RSUs, as applicable, held by Messrs. Diller and Levin would have been accelerated.

In addition, in the case of Mr. Diller only, under the Equity and Bonus Compensation Agreement, dated August 24, 1995, between IAC and Mr. Diller, we agreed that to the extent any payment or distribution by IAC to or for the benefit of Mr. Diller (whether under the terms of the related agreement or otherwise) would be subject to the excise tax imposed by §4999 of the Internal Revenue Code, or any interest or penalties are incurred by Mr. Diller with respect to such excise tax, then Mr. Diller would be entitled to a gross-up payment covering the excise taxes and related interest and penalties. Given that Mr. Diller would not have received any payment or other benefits upon an assumed change in control of IAC at the end of 2015, the Company does not believe that any excise tax would be imposed or that any gross-up would be required.

Mr. Kaufman

Upon a termination without cause or resignation for good reason on December 31, 2015, pursuant to the terms of his amended employment agreement, Mr. Kaufman would have been entitled to:

·                  the partial vesting of outstanding and unvested RSUs in amounts equal to the number that would have otherwise vested in accordance with the terms of such awards during the 12-month period following such termination of employment; and

·                  continue to have the ability to exercise his vested stock options through June 30, 2017.

No payments would have been made to Mr. Kaufman pursuant to any agreement between the Company and Mr. Kaufman upon a change in control of IAC on December 31, 2015. Upon a termination without cause or resignation for good reason following a change in control of IAC on December 31, 2015, in accordance with our omnibus stock and annual incentive plans and the related award agreements, the vesting of all then outstanding and unvested RSUs held by Mr. Kaufman would have been accelerated. For Mr. Kaufman, “good reason” means a material breach of his amended employment agreement by the Company that it fails to remedy.

Mr. Kip

Upon a termination without cause or voluntary resignation on December 31, 2015, pursuant to the terms of an oral agreement between Mr. Kip and the Company that was reached following his tenure as the Company’s Chief Financial Officer, Mr. Kip would have been entitled to:

·                  receive 12 months of his base salary, subject to the execution and non-revocation of a release and compliance with post-termination confidentiality, non-solicitation of employees (18 months), non- solicitation of business partners (12 months) and assignment of certain employee developments covenants, and subject to offset for any amounts earned from other employment during the severance period;

·                  the partial vesting of outstanding and unvested stock options and RSUs in amounts equal to the number that would have otherwise vested in accordance with the terms of such awards during the 12-month period following such termination of employment; and

·                  continue to have the ability to exercise his vested stock options through June 30, 2017.

No payments would have been made to Mr. Kip pursuant to any agreement between the Company and Mr. Kip upon a change in control of IAC on December 31, 2015. Lastly, upon a termination without cause or resignation for good reason following a change in control of IAC on December 31, 2015, in accordance with the applicable omnibus stock and annual incentive plans and the related award agreements, the vesting of all then outstanding and unvested stock options and RSUs held by Mr. Kip would have been accelerated.

Mr. Winiarski

Upon a termination without cause or resignation for good reason on December 31, 2015, pursuant to the terms of his employment agreement, Mr. Winiarski would have been entitled to:

·                  receive 12 months of his base salary, subject to the execution and non-revocation of a release and compliance with post-termination confidentiality, non-solicitation of employees (18 months), non- solicitation of business partners (12 months) and assignment of certain employee developments covenants, and subject to offset for any amounts earned from other employment during the severance period;

·                  the partial vesting of outstanding and unvested stock options and RSUs in amounts equal to the number that would have otherwise vested in accordance with the terms of such awards during the 12-month period following such termination of employment; and

·                  continue to have the ability to exercise his vested stock options through June 30, 2017.

No payments would have been made to Mr. Winiarski pursuant to any agreement between the Company and Mr. Winiarski upon a change in control of IAC on December 31, 2015. Upon a termination without cause or resignation for good reason following a change in control of IAC on December 31, 2015, in accordance with our omnibus stock and annual incentive plans and the related award agreements, the vesting of all then outstanding and unvested stock options and RSUs held by Mr. Winiarski would have been accelerated.

For Mr. Winiarski, “good reason” includes: (i) a material adverse change in his title, duties or level of responsibilities, (ii) a material reduction in his base salary, (iii) a material relocation of his principal place of employment outside of the New York City metropolitan area, and (iv) a material adverse change in reporting structure such that he is no longer reporting to a Company officer with a title of Executive Vice President or above that reports to the Company’s Chairman or Vice Chairman, in each case, without the written consent of Mr. Winiarski or that is not cured promptly after notice.

DIRECTOR COMPENSATION

Non-Employee Director Compensation Arrangements.  The Nominating Committee has primary responsibility for establishing non-employee director compensation arrangements, which have been designed to provide competitive compensation necessary to attract and retain high quality non- employee directors and to encourage ownership of Company stock to further align the interests of our directors with those of our stockholders. Arrangements in effect during 2015 provided that: (i) each member of the Board receive an annual retainer in the amount of $50,000, (ii) each member of the Audit and Compensation and Human Resources Committees (including their respective Chairpersons) receive an additional annual retainer in the amount of $10,000 and $5,000, respectively, and (iii) the Chairpersons of each of the Audit and Compensation and Human Resources Committees receive an additional annual chairperson retainer in the amount of $20,000, with all amounts being paid quarterly, in arrears.

In addition, these arrangements also provide that each non-employee director receive a grant of RSUs with a dollar value of $250,000 upon his or her initial election to the Board and annually thereafter upon re-election on the date of IAC’s annual meeting of stockholders, the terms of which provide for: (i) vesting in three equal annual installments commencing on the first anniversary of the grant date, (ii) cancellation and forfeiture of unvested RSUs in their entirety upon termination of service for IAC and its affiliates and (iii) full acceleration of vesting upon a change in control of IAC. The Company also reimburses non-employee directors for all reasonable expenses incurred in connection with attendance at IAC Board and Board committee meetings.

Deferred Compensation Plan for Non-Employee Directors.  Under IAC’s Deferred Compensation Plan for Non-Employee Directors, non-employee directors may defer all or a portion of their Board and Board committee fees. Eligible directors who defer all or any portion of these fees can elect to have such deferred fees applied to the purchase of share units, representing the number of shares of IAC common stock that could have been purchased on the relevant date, or credited to a cash fund. If any dividends are paid on IAC common stock, dividend equivalents will be credited on the share units. The cash fund will be credited with deemed interest at an annual rate equal to the weighted average prime lending rate of JPMorgan Chase Bank. After a director ceases to be a member of the Board, he or she will receive: (i) with respect to share units, such number of shares of IAC common stock as the share units represent, and (ii) with respect to the cash fund, a cash payment in an amount equal to deferred amounts, plus accrued interest. These payments are generally made in a one lump sum installment after the relevant director leaves the Board and otherwise in accordance with the plan.

2015 Non-Employee Director Compensation.  The table below provides the amount of: (i) fees earned by non-employee directors for services performed during 2015 and (ii) the grant date fair value of RSU awards granted in 2015.

(1)                                 Fees earned by, and the grant date fair value of RSU awards granted to, a former director (Sonali De Rycker) in 2015 were $50,000 in fees earned and deferred and an IAC RSU award with a grant date fair value of $249,936.

(2)                                 Represents the dollar value of fees deferred in the form of share units by the relevant director under IAC’s Deferred Compensation Plan for Non-Employee Directors. Pursuant to the terms of the plan, share units are credited with the number of share units that could have been purchased with the dollar amount of ordinary cash dividends payable on the number of share units outstanding on the relevant dividend record date, with each share unit being treated as if it was one share of IAC common stock. Share units issued as credit for ordinary cash dividends paid are settled at the same time as the underlying share units (after the relevant director leaves the Board and otherwise in accordance with the plan).

Pursuant to the plan, share units held by each of Messrs. Bronfman, Lourd, Rosenblatt, Spoon and von Furstenberg and Mmes. Clinton and De Rycker during 2015 were credited with share units for ordinary cash dividends paid in 2015 with a value of approximately $30,482, $28,571, $7,095, $37,076, $4,756, $4,215 and $2,457, respectively.

(3)                                 Amounts presented represent the grant date fair value of these RSU awards, which was calculated using the closing price of IAC common stock on the grant date.

(4)                                 The differences in the amounts shown above among directors reflect, as applicable, committee service (or lack thereof), which varies among directors.

(1)                                 Information excludes 6,401,414 shares that have been reserved and may be issuable upon the settlement of subsidiary-level phantom equity awards (without giving effect to the withholding of shares to cover taxes due) that relate to subsidiaries of IAC and Match Group, Inc. (“Match Group”), based on the estimated values of such awards as of December 31, 2015.

To the extent that 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. As of December 31, 2015, 4,101,657 shares of IAC common stock (included within the 6,401,414 shares of IAC common stock disclosed above) would have been issuable upon the settlement of subsidiary-level phantom equity awards that relate to Match Group subsidiaries.

Item 13.    Certain Relationships and Related Transactions, and Director Independence

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Review of Related Person Transactions

The Audit Committee has a formal, written policy that requires an appropriate review of all related person transactions by the Audit Committee, as required by Marketplace Rules governing conflict of interest transactions. For purposes of this policy, as amended, consistent with the Marketplace Rules, the terms “related person” and “transaction” are determined by reference to Item 404(a) of Regulation S-K under the Securities Act of 1933, as amended (“Item 404”). During 2015, in accordance with this policy, Company management was required to determine whether any proposed transaction, arrangement or relationship with a related person fell within the definition of “transaction” set forth in Item 404, and if so, review such transaction with the Audit Committee.

Relationships Involving Significant Stockholders, Named Executives and Directors

Relationships Involving Mr. Diller.  Pursuantaddition, pursuant to an amended and restated governance agreement between IAC and Mr. Diller, for so long as Mr. Diller serves as IAC’s Chairman and Senior Executive and he beneficially owns (within the meaning of Rule 13d-3 of the Securities Exchange Act of 1934, as amended) at least 5,000,000 shares of Class B common stock and/or common stock in which he has a pecuniary interest (including IAC securities beneficially owned by him directly and indirectly through trusts for the benefit of certain members of his family), he generally has the right to consent to limited matters in the event that IAC’s ratio of total debt to EBITDA (as defined in the governance agreement) equals or exceeds four to one over a continuous twelve-month period.

In 2001,
