Whether or not you plan to attend the Annual Meeting, please take the time to vote online, by telephone or, if you receive a printed proxy card, by returning a marked, signed and dated proxy card.

At the Annual Meeting, stockholders will be asked:

        1.     to elect 12 members of IAC's Board of Directors, each to hold office for a one-year term ending on the date of the next succeeding annual meeting of stockholders or until such director's successor shall have been duly elected and qualified (or, if earlier, such director's removal or resignation from IAC's Board of Directors);

        3.     to transact such other business as may properly come before the meeting and any related adjournments or postponements.

        IAC's Board of Directors has set April 29, 2015 as the record date for the Annual Meeting.

PROXY STATEMENT

QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING AND VOTING

Q:    Why did I receive a Notice of Internet Availability of Proxy Materials?

A:

In accordance with rules adopted by the Securities and Exchange Commission (the "SEC"), we elected to deliver this Proxy Statement and our 2014 Annual Report on Form 10-K to the majority of our stockholders online in lieu of mailing printed copies of these materials to each of our stockholders (the "Notice Process"). If you received a Notice of Internet Availability of Proxy Materials (the "Notice") by mail, you will not receive printed copies of our proxy materials unless you request them. Instead, the Notice provides instructions on how to access this Proxy Statement and our 2014 Annual Report on Form 10-K online, as well as how to obtain printed copies of these materials by mail. We believe that the Notice Process allows us to provide our stockholders with the information they need in a more timely manner than if we had elected to mail printed materials, while reducing the environmental impact of, and lowering the costs associated with, the printing and distribution of our proxy materials.

The Notice is being mailed on or about May 12, 2015 to stockholders of record at the close of business on April 29, 2015 and this Proxy Statement and our 2014 Annual Report on Form 10-K will be available at www.proxyvote.com beginning on May 12, 2015. If you received a Notice by mail but would rather receive printed copies of our proxy materials, please follow the instructions included in the Notice. You will not receive a Notice if you have previously elected to receive printed copies of our proxy materials.

Q:

Can I vote my shares by filling out and returning the Notice?

A:

No. However, the Notice provides instructions on how to vote your shares by way of completing and submitting your proxy online or by phone, by requesting and returning a written proxy card by mail or by submitting a ballot in person at the Annual Meeting.

Q:

Who is entitled to vote at the Annual Meeting?

A:

Holders of IAC common stock and Class B common stock at the close of business on April 29, 2015, the record date for the Annual Meeting established by IAC's Board of Directors, are entitled to receive notice of the Annual Meeting and to vote their shares at the Annual Meeting and any related adjournments or postponements.

As of the close of business on April 29, 2015, there were 76,350,690 shares of IAC common stock and 5,789,499 shares of Class B common stock outstanding and entitled to vote. Holders of IAC common stock are entitled to one vote per share and holders of Class B common stock are entitled to ten votes per share.

Q:

What is the difference between a stockholder of record and a stockholder who holds stock in street name?

A:

If your IAC shares are registered in your name, you are a stockholder of record. If your IAC shares are held in the name of your broker, bank or other holder of record, your shares are held in street name.

You may examine a list of the stockholders of record as of the close of business on April 29, 2015 for any purpose germane to the Annual Meeting during normal business hours during the 10-day period preceding the date of the meeting at IAC's corporate headquarters, located at 555 West 18th Street, New York, New York 10011.

Q:

What are the quorum requirements for the Annual Meeting?

A:

The presence at the Annual Meeting, in person or by proxy, of holders having a majority of the total votes entitled to be cast by holders of IAC common stock and Class B common stock at the Annual Meeting constitutes a quorum. When the holders of IAC common stock vote as a separate class, the presence at the Annual Meeting of holders of a majority of the total votes entitled to be cast by holders of IAC common stock is required for a quorum to be met. Shares of IAC common stock and Class B common stock represented by proxy will be treated as present at the Annual Meeting for purposes of determining whether there is a quorum, without regard to whether the proxy is marked as casting a vote or abstaining.

Q:

The election of each of Edgar Bronfman, Jr., Chelsea Clinton, Sonali De Rycker, Barry Diller, Michael D. Eisner, Bonnie Hammer, Victor A. Kaufman, David Rosenblatt and Alexander von Furstenberg as directors requires the affirmative vote of a plurality of the total number of votes cast by the holders of shares of IAC common stock and Class B common stock voting together as a single class (hereinafter referred to as IAC capital stock), with each share of common stock and Class B common stock representing the right to one and ten votes, respectively.

The election of each of Bryan Lourd, Alan G. Spoon and Richard F. Zannino as directors requires the affirmative vote of a plurality of the total number of votes cast by the holders of the shares of IAC common stock voting as a separate class.

The Board recommends that our stockholders vote FOR the election of each of the director nominees named above.

The Board recommends that our stockholders vote FOR the ratification of the appointment of Ernst & Young LLP as IAC's independent registered public accounting firm for 2015.

Q:

Could other matters be decided at the Annual Meeting?

A:

As of the date of this Proxy Statement, we did not know of any matters to be raised at the Annual Meeting, other than those referred to in this Proxy Statement.

If other matters are properly presented at the Annual Meeting for consideration, the three IAC officers who have been designated as proxies for the Annual Meeting, Joanne Hawkins, Jeffrey W. Kip and Gregg Winiarski, will have the discretion to vote on those matters for stockholders who have submitted their proxy.

Q:

What do I need to do now to vote at the Annual Meeting?

A:

IAC's Board of Directors is soliciting proxies for use at the Annual Meeting. Stockholders may submit proxies to instruct the designated proxies to vote their shares in any of three ways:

•

Submitting a Proxy Online:  Submit your proxy via the Internet. The website for Internet proxy voting is www.proxyvote.com. Internet proxy voting is available 24 hours a day and will close at 11:59 p.m., Eastern Standard Time, on Tuesday, June 23, 2015;

•

Submitting a Proxy by Telephone:  Submit your proxy by telephone by using the toll-free telephone number provided on your proxy card (1.800.690.6903). Telephone voting is available 24 hours a day and will close at 11:59 p.m., Eastern Standard Time, on Tuesday, June 23, 2015; or

•

Submitting a Proxy by Mail:  If you choose to submit your proxy by mail, simply mark your proxy, date and sign it, and return it in the postage-paid envelope provided or to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, New York 11717.

If you were a stockholder of record on April 29, 2015 or if you have a legal proxy from your broker, bank or other holder of record identifying you as a beneficial owner of IAC shares as of that date, you may vote in person by attending the Annual Meeting.

For IAC shares held in street name, holders may submit a proxy online or by telephone if their broker, bank or other holder of record makes these methods available. If you submit a proxy online or by telephone, do not request and return a printed proxy card from IAC or from your broker, bank or other holder of record. If you hold your shares through a broker, bank or other holder of record, follow the voting instructions you receive from your broker, bank or other holder of record.

Q:

If I hold my IAC shares in street name, will my broker, bank or other holder of record vote these shares for me?

A:

If you hold IAC shares in street name, you must provide your broker, bank or other nominee with instructions in order to vote these shares. If you do not provide voting instructions, whether your shares can be voted depends on the type of item being considered for a vote.

Non-Discretionary Items.    The election of directors is a non-discretionary item and may NOT be voted on by your broker, bank or other nominee absent specific voting instructions from you. If your bank, broker or other nominee does not receive specific voting instructions from you, a "broker non-vote" will occur in the case of your shares of IAC common stock for this proposal.

Table of Contents

Discretionary Items.    The ratification of Ernst & Young LLP as IAC's independent registered public accounting firm for 2015 is a discretionary item. Generally, brokers, banks and other nominees that do not receive voting instructions may vote on this proposal in their discretion and these votes will be counted for purposes of determining a quorum.

Q:

What effect do abstentions and broker non-votes have on quorum requirements and the voting results for each proposal to be voted on at the Annual Meeting?

A:

Abstentions and broker non-votes are counted as present for purposes of determining a quorum. Abstentions are treated as shares present and entitled to vote and, as a result, have the same effect as a vote against any proposal for which the voting standard is based on the number of shares present at the Annual Meeting (the auditor ratification proposal) and have no impact on the vote on any proposal for which the vote standard is based on the votes cast at the meeting (the election of directors). Broker non-votes are not treated as shares entitled to vote and, as a result, have no effect on the outcome of any of the proposals to be voted on by stockholders at the Annual Meeting; provided, however, that brokers have discretionary authority to vote on the auditor ratification proposal.

Q:

Can I change my vote or revoke my proxy?

A:

Yes. If you are a stockholder of record, you may change your vote or revoke your proxy at any time before the vote at the Annual Meeting by:

•

submitting a later-dated proxy relating to the same shares online, by telephone or by mail prior to the vote at the Annual Meeting;

•

delivering a written notice, bearing a date later than your proxy, stating that you revoke the proxy; or

•

attending the Annual Meeting and voting in person (although attendance at the Annual Meeting will not, by itself, revoke a proxy).

To change your vote or revoke your proxy, follow the instructions provided on the Notice or the proxy card to do so online or by telephone, or send a written notice or a new proxy card to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, New York 11717.

Q:

How are proxies solicited and who bears the related costs?

A:

IAC bears all expenses incurred in connection with the solicitation of proxies. In addition to solicitations by mail, directors, officers and employees of IAC may solicit proxies from stockholders by telephone, letter, facsimile, e-mail or in person. Following the initial mailing of the Notice and proxy materials, IAC will request brokers, banks and other holders of record to forward copies of these materials to persons for whom they hold shares of IAC common stock and to request authority for the exercise of proxies. In such cases, IAC, upon the request of these holders, will reimburse these parties for their reasonable expenses.

Q:

What should I do if I have questions regarding the Annual Meeting?

A:

If you have any questions about the Annual Meeting, would like to obtain directions to attend the Annual Meeting and vote in person or would like copies of any of the documents referred to in this Proxy Statement, you should contact IAC Investors Relations at 1.212.314.7400 or ir@iac.com.

Corporate Governance

        Leadership Structure.    The Company's business and affairs are overseen by its Board of Directors, which currently has twelve members. There are two management representatives on the Board and, of the ten remaining current directors, nine are independent. The Board has an Audit Committee, Compensation and Human Resources Committee and Nominating Committee, each comprised solely of independent directors, as well as an Executive Committee. For more information regarding director independence and our Board Committees, see the discussion under Director Independence beginning on page 11 and Board Committees beginning on page 13. All of our directors play an active role in Board matters, are encouraged to communicate among themselves and directly with the Chairman and Senior Executive and have full access to Company management at all times.

        Our independent directors meet in scheduled executive sessions without management present at least twice a year and may schedule additional meetings as they deem appropriate. We do not have a lead independent director or any other formally appointed leader for these sessions. The independent membership of our Audit, Compensation and Human Resources and Nominating Committees ensures that directors with no ties to Company management are charged with oversight for all financial reporting and executive compensation related decisions made by Company management, as well as for recommending candidates for Board membership. At each regularly scheduled Board meeting, the Chair of each of these committees provides the full Board with an update of all significant matters discussed, reviewed, considered and/or approved by the relevant committee since the last regularly scheduled Board meeting.

        Mr. Diller currently serves as both our Chairman and Senior Executive and has held both positions since December 2010. The Company has concluded that separate roles of Senior Executive and Chief Executive Officer are not necessary given that each of the Company's three principal areas of focus (The Match Group, Search & Applications and Media) has a fully developed management team reporting directly to senior IAC management and the related belief that a less centralized operating structure that pushes talent and decision-making closer to the Company's businesses is the best way to achieve the Company's long-term growth objectives. At this time, we believe that this leadership structure is the most appropriate one for the Company and its stockholders.

        Risk Oversight.    Company management is responsible for assessing and managing the Company's exposure to various risks on a day-to-day basis, which responsibilities include the creation of appropriate risk management programs and policies. Company management has developed and implemented guidelines and policies to identify, assess and manage significant risks facing the Company. In developing this framework, the Company recognized that leadership and success are impossible without taking risks; however, the imprudent acceptance of risk or the failure to appropriately identify and mitigate risks could adversely impact stockholder value. The Board is responsible for overseeing management in the execution of its responsibilities and for assessing the Company's approach to risk management. The Board exercises these responsibilities periodically as part of its meetings and through discussions with Company management, as well as through the Board's Audit and Compensation and Human Resources Committees, which examine various components of financial and compensation-related risks, respectively, as part of their responsibilities. In addition, an overall review of risk is inherent in the Board's consideration of the Company's long-term strategies and in the transactions and other matters presented to the Board, including significant capital expenditures, acquisitions and divestitures and financial matters. The Board's role in risk oversight of the Company is consistent with the Company's leadership structure, with the Chairman and Senior Executive and other members of senior management having responsibility for assessing and managing the Company's risk exposure, and the Board and its committees providing oversight in connection with those efforts.

        Compensation Risk Assessment.    We periodically conduct risk assessments of our compensation policies and practices for our employees, including those related to our executive compensation

10

---

Table of Contents

programs. The goal of these assessments is to determine whether the general structure of the Company's compensation policies and programs and the administration of these programs pose any material risks to the Company. The findings of any risk assessment are discussed with the Compensation and Human Resources Committee. Based upon our assessments, we believe that our compensation policies and programs do not encourage excessive or unnecessary risk-taking and are not reasonably likely to have a material adverse effect on the Company.

        Director Independence.    Under the Marketplace Rules of The Nasdaq Stock Market (the "Marketplace Rules"), the Board has a responsibility to make an affirmative determination that those members of the Board who serve as independent directors do not have any relationships that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In connection with the independence determinations described below, the Board reviewed information regarding transactions, relationships and arrangements relevant to independence, including those required by the Marketplace Rules. This information is obtained from director responses to questionnaires circulated by Company management, as well as from Company records and publicly available information. Following this determination, Company management monitors those transactions, relationships and arrangements that were relevant to such determination, as well as periodically solicits updated information potentially relevant to independence from internal personnel and directors, to determine whether there have been any developments that could potentially have an adverse impact on the Board's prior independence determination.

        In February 2015, the Board determined that each of Messrs. Bronfman, Eisner, Lourd, Rosenblatt, Spoon and Zannino and Mmes. Clinton, De Rycker and Hammer is independent. In connection with this determination, the Board considered that in the ordinary course of business, IAC and its businesses sell products and services to, purchase products and services from, co-invest with and develop and produce projects with, companies at which certain directors are employed or serve as directors, or over which certain directors otherwise exert control. Furthermore, the Board considered whether there were any payments made to (or received from) such entities by IAC and its businesses. Specific payments the Board considered are as follows:

•

the payment of a license fee (for the online distribution of a film) by an IAC business to a portfolio company of Tornante (Mr. Eisner is Chairman of Tornante);



•

the payment of license fees (for the distribution of programming) to an IAC business by certain businesses overseen and managed by Ms. Hammer in her role as Chairman of NBCUniversal Cable Entertainment (Ms. Hammer is not a named executive officer of the ultimate parent corporation that owns and controls NBCUniversal);



•

payments for services made by an IAC business to CAA, where Mr. Lourd is Managing Director;



•

a co-investment by IAC in an entity in which Polaris Partners was an existing equity investor, as well as payments for services between the Company and certain Polaris Partners portfolio companies (Mr. Spoon was a Managing General Partner (now Partner Emeritus) of Polaris Partners); and



•

payments for data licensing services made by an IAC business to a portfolio company of CCMP Capital Advisors, LLC, where Mr. Zannino is a Managing Director and member of the firm's Investment Committee. The agreement pursuant to which the IAC business made these payments was entered into by the parties before Mr. Zannino began serving on the Board and before CCMP acquired the company.

        In the case of Mmes. Clinton and De Rycker and Mr. Rosenblatt, there were no such payments known to Company management for the Board to consider. Of the remaining incumbent directors, Messrs. Diller and Kaufman are executive officers of the Company and Mr. von Furstenberg is Mr. Diller's stepson. Given these relationships, none of these directors is independent.

Table of Contents

        In addition to the satisfaction of the director independence requirements set forth in the Marketplace Rules, members of the Audit and Compensation and Human Resources Committees have also satisfied separate independence requirements under the current standards imposed by the SEC and the Marketplace Rules for audit committee members and by the SEC, the Marketplace Rules and the Internal Revenue Service for compensation committee members.

        In February 2014, the Board determined that two former directors, Donald R. Keough and Arthur C. Martinez, were independent. In connection with this determination, the Board considered payments for services made by an IAC business to Allen & Company, where Mr. Keough then served as Chairman (in a non-executive capacity). In the case of Mr. Martinez, there were no such payments known to Company management for the Board to consider.

        Director Nominations.    The Nominating Committee identifies, reviews and evaluates individuals qualified to become Board members and recommends candidates to the Board. While there are no specific requirements for eligibility to serve as a director of IAC, in evaluating candidates, the Nominating Committee will consider (regardless of how the candidate was identified or recommended) whether the professional and personal ethics and values of the candidate are consistent with those of IAC, whether the candidate's experience and expertise would be beneficial to the Board, whether the candidate is willing and able to devote the necessary time and energy to the work of the Board and whether the candidate is prepared and qualified to represent the best interests of IAC's stockholders. While the Board does not have a formal diversity policy, the Nominating Committee also considers the overall diversity of the experiences, characteristics, attributes, skills and backgrounds of candidates relative to those of other Board members and those represented by the Board as a whole to ensure that the Board has the right mix of skills, expertise and background.

        The Board does not have a formal policy regarding the consideration of director nominees recommended by stockholders, as historically IAC has not received such recommendations. However, the Board would consider such recommendations if made in the future. Stockholders who wish to make such a recommendation should send the recommendation to IAC, 555 West 18^th Street, New York, New York 10011, Attention: Corporate Secretary. The envelope must contain a clear notation that the enclosed letter is a "Director Nominee Recommendation." The letter must identify the author as a stockholder, provide a brief summary of the candidate's qualifications and history, together with an indication that the recommended individual would be willing to serve (if elected), and must be accompanied by evidence of the sender's stock ownership. Any director recommendations will be reviewed by the Corporate Secretary and the Chairman, and if deemed appropriate, forwarded to the Nominating Committee for further review. If the Nominating Committee believes that the candidate fits the profile of a director described above, the recommendation will be shared with the entire Board.

        Communications with the IAC Board.    Stockholders who wish to communicate with IAC's Board of Directors or a particular director may send such communication to IAC, 555 West 18^th Street, New York, New York 10011, Attention: Corporate Secretary. The mailing envelope must contain a clear notation indicating that the enclosed letter is a "Stockholder—Board Communication" or "Stockholder—Director Communication." All such letters must identify the author as a stockholder, provide evidence of the sender's stock ownership and clearly state whether the intended recipients are all members of the Board or a particular director or directors. The Corporate Secretary will then review such correspondence and forward it to the Board, or to the specified director(s), if appropriate.

The Board and Board Committees

        The Board.    The Board met four times and acted by written consent three times during 2014. During 2014, all then incumbent directors attended at least 75% of the meetings of the Board and the Board committees on which they served. Directors are not required to attend annual meetings of IAC stockholders. One member of the Board of Directors attended IAC's 2014 Annual Meeting of Stockholders.

The Compensation and Human Resources Committee may also delegate to one or more of the Company's executive officers the authority to make grants of equity-based compensation to eligible individuals (other than directors or executive officers) to the extent allowed under applicable law. For additional information on IAC's processes and procedures for the consideration and determination of executive compensation and the related roles of the Compensation and Human Resources Committee, Company management and consultants, see the discussion under Compensation Discussion and Analysis generally beginning on page 17.

        Executive Committee.    The Executive Committee has all the power and authority of the Board of Directors of IAC, except those powers specifically reserved to the Board by Delaware law or IAC's organizational documents.

AUDIT COMMITTEE MATTERS

Audit Committee Report

        The Audit Committee functions pursuant to a written charter adopted by the Board of Directors, the most recent version of which was filed as Appendix A to IAC's 2014 Annual Meeting proxy statement. The Audit Committee charter governs the operations of the Audit Committee and sets forth its responsibilities, which include providing assistance to the Board of Directors with the monitoring of: (i) the integrity of IAC's financial statements, (ii) the effectiveness of IAC's internal control over financial reporting, (iii) the qualifications and independence of IAC's independent registered public accounting firm, (iv) the performance of IAC's internal audit function and independent registered public accounting firm, (v) IAC's risk assessment and risk management policies as they relate to financial and other risk exposures and (vi) the compliance by IAC with legal and regulatory requirements. It is not the duty of the Audit Committee to plan or conduct audits or to determine that IAC's financial statements and disclosures are complete, accurate and have been prepared in accordance with generally accepted accounting principles and applicable rules and regulations. These are the responsibilities of management and IAC's independent registered public accounting firm.

        In fulfilling its responsibilities, the Audit Committee has reviewed and discussed the audited consolidated financial statements of IAC for the fiscal year ended December 31, 2014 with IAC's management and Ernst & Young LLP, IAC's independent registered public accounting firm.

        The Audit Committee has discussed with Ernst & Young the matters required to be discussed by PCAOB Auditing Standard No. 16, "Communications with Audit Committees." In addition, the Committee has received the written disclosures and the letter from Ernst & Young required by applicable requirements of the Public Company Accounting Oversight Board regarding Ernst & Young's communications with the Audit Committee concerning independence and has discussed with Ernst & Young its independence from IAC and its management.

        In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements for IAC for the fiscal year ended December 31, 2014 be included in IAC's Annual Report on Form 10-K for the year ended December 31, 2014 for filing with the SEC.

Audit and Non-Audit Services Pre-Approval Policy

        The Audit Committee has a policy governing the pre-approval of all audit and permitted non-audit services performed by IAC's independent registered public accounting firm in order to ensure that the provision of these services does not impair such firm's independence from IAC and its management. Unless a type of service to be provided by IAC's independent registered public accounting firm has received general pre-approval, it requires specific pre-approval by the Audit Committee. Any proposed services in excess of pre-approved cost levels also require specific pre-approval by the Audit Committee. In all pre-approval instances, the Audit Committee considers whether such services are consistent with SEC rules regarding auditor independence.

        All Tax services require specific pre-approval by the Audit Committee. In addition, the Audit Committee has designated specific services that have the pre-approval of the Audit Committee (each of which is subject to pre-approved cost levels) and has classified these pre-approved services into one of three categories: Audit, Audit-Related and All Other (excluding Tax). The term of any pre-approval is 12 months from the date of the pre-approval, unless the Audit Committee specifically provides for a different period. The Audit Committee revises the list of pre-approved services from time to time. Pre-approved fee levels for all services to be provided by IAC's independent registered public accounting firm are established periodically from time to time by the Audit Committee.

        Pursuant to the pre-approval policy, the Audit Committee may delegate its authority to grant pre-approvals to one or more of its members, and has currently delegated this authority to its Chairman. The decisions of the Chairman (or any other member(s) to whom such authority may be delegated) to grant pre-approvals must be presented to the full Audit Committee at its next scheduled meeting. The Audit Committee may not delegate its responsibilities to pre-approve services to management.

COMPENSATION DISCUSSION AND ANALYSIS

Philosophy and Objectives

        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. The form of equity awards has changed from time to time over the years, and in 2008 we introduced non-qualified stock options as the predominant equity incentive vehicle for our executives. This switch was made 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 2014 one of our executives was awarded restricted stock units as described below.

Table of Contents

        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 Compensation Discussion and Analysis, the "Committee") has primary responsibility for establishing the compensation of the Company's executive officers. All compensation decisions referred to throughout this Compensation Disclosure and Analysis section have been made by the Committee, based (in part) on recommendations from Mr. Diller (as described below). The Committee currently consists of Mr. Rosenblatt and Ms. Hammer, and at the time equity awards were granted in 2014, the Committee consisted of Messrs. Keough, Martinez and Rosenblatt.

        The executive officers participate in structuring Company-wide compensation programs and in establishing appropriate bonus and equity pools and Mr. Diller meets with the Committee at least annually to discuss compensation packages for the executive team. In early 2015, Mr. Diller met with the Committee and discussed his views of corporate and individual executive officer performance for 2014 for Messrs. Kaufman, Kip and Winiarski, and his recommendation for annual bonuses for those executive officers. Mr. Diller also discussed his own performance with the Committee. Following these discussions, the Committee met in executive sessions to discuss Mr. Diller's 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 2014.

        In addition, from time to time, the Company may solicit survey or peer compensation data from various consulting firms. In 2014, 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 2014.

        In late 2014, the Committee engaged Compensation Advisory Partners LLC ("CAP") to assist the Committee in its consideration of a long-term incentive award for Mr. Diller, 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 2014.

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

        2014 Bonuses.    For 2014, the Committee predicated the payment of bonuses to executive officers on attaining: (i) EBITA in any of the four consecutive calendar quarters beginning with the second quarter of 2014 at least equal to EBITA in the corresponding calendar quarter twelve months before, (ii) revenue in any of the four consecutive calendar quarters beginning with the second quarter of 2014 at least equal to revenue in the corresponding calendar quarter twelve months before or (iii) share price growth of at least 5% over $66.19 (the closing price of the Company's common stock on the date the goals were established) on any 20 trading days during the period beginning on February 12, 2014 through December 31, 2014. The revenue and share price targets were met, as determined by the Committee during the fourth quarter of 2014. 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:

•

Revenue and Adjusted EBITDA Results.  Revenue increased modestly over the prior year, reflecting growth in The Match Group segment, partially offset by challenges in the Search & Applications segment and revenue declines in the Media segment resulting from certain dispositions. Adjusted EBITDA declined 9% for the year, reflecting increased selling and marketing expenses, partially offset by the impact of certain acquisitions;

Table of Contents

•

Capitalization and Cash Position.  The Company increased its quarterly dividend over 40% during the year and repatriated a meaningful amount of cash to its stockholders during 2014 by way of quarterly cash dividends. In addition, the Company generated strong cash flow from its operations during the year, positioning itself to take advantage of investment opportunities that may arise;



•

Successful Completion of Transactions.  The Company continued its disciplined approach to acquisitions and investments during 2014, completing over $300 million in acquisitions, investments and purchases of non-controlling interests. These transactions allowed the Company to expand its product offerings and diversify revenue streams. The larger of these transactions included the acquisitions of The Princeton Review and certain assets of ValueClick, Inc.; and



•

Other Initiatives.  The Company, in connection with its continuing review of its collection of assets, increased its investment in those businesses where we believe there is upside opportunity, and restructured or sold certain non-core businesses.

        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. In particular, the Committee considered the following: (i) with respect to Mr. Diller, his role in providing strategic direction for the Company overall, (ii) with respect to Mr. Kip, his continuing successful management of operational and cost-containment initiatives, (iii) with respect to Mr. Kaufman, his participation in strategic oversight of the Company, and (iv) with respect to Mr. Winiarski, his role in managing the successful completion of a number of acquisitions and investments during the year.

        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. In addition, the Committee considered achievements in 2014 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 2014 bonuses for our executive officers were lower than those for 2013, reflecting the Company's overall performance in 2014 relative to the prior year. 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

20

Table of Contents

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.

        2014 Equity Awards.    In March 2014, the Committee granted 125,000 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. The Committee did not grant any equity awards to Mr. Diller in 2014 after considering his earning history, outstanding long-term compensation arrangements and potential realizable values from those long-term arrangements.

        In February 2014, 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.

        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 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.

        To assist the Committee, the Company engaged CAP to evaluate various long-term incentive alternatives and make recommendations to the Committee. 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).

21

Table of Contents

        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.

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 24 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 2014, 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.

22

Table of Contents

        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.

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.

2014 Option Exercises and Stock Vested

        The table below provides information regarding the number of shares acquired by our named executives upon the exercise of IAC stock options and the vesting of IAC RSU awards in 2014 and the related value realized, excluding the effect of any applicable taxes.

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 IAC equity awards and/or extended post-termination exercise periods for IAC 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, 2014.

        Certain amounts that would become payable to our named executives upon the events described above (as and if applicable), assuming that the relevant event occurred on December 31, 2014, 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 IAC stock options and IAC RSUs outstanding on December 31, 2014 and the closing price of IAC common stock ($60.79) on December 31, 2014. 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.

Mr. Diller

        Upon a termination without cause or due to death or disability or a resignation for good reason on December 31, 2014, in accordance with the agreement governing Mr. Diller's 2005 stock options, all of Mr. Diller's vested and outstanding stock options governed by such agreement (705,734 IAC stock options, 279,978 HSNi stock options, 759,941 Interval stock options, 1,120,435 Live Nation stock options and 126,656 Tree.com stock options) would have remained outstanding and exercisable through June 7, 2015 (their expiration date). For Mr. Diller, "good reason" is defined as a reduction in his base salary, a relocation outside of the New York City metropolitan area or a material and demonstrable adverse change in the nature and scope of his duties from those in effect on June 7, 2005, in each case, without his written consent.

Table of Contents

        No payments would have been made to Mr. Diller pursuant to any agreement between the Company and Mr. Diller upon a change in control of IAC on December 31, 2014. Upon a termination without cause or resignation for good reason following a change in control of IAC on December 31, 2014, in accordance with the applicable omnibus stock and incentive plan and the related award agreement, the vesting of all then outstanding and unvested IAC stock options held by Mr. Diller would have been accelerated.

        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 the payments Mr. Diller would receive upon an assumed change in control of IAC at the end of 2014, 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, 2014, pursuant to the terms of his amended employment agreement, Mr. Kaufman would have been entitled to:

•

the partial vesting of outstanding and unvested IAC stock options and IAC 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 IAC stock options through June 30, 2016.

        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, 2014. Upon a termination without cause or resignation for good reason following a change in control of IAC on December 31, 2014, in accordance with our omnibus stock and annual incentive plans and the related award agreements, the vesting of all then outstanding and unvested IAC stock options and IAC 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 resignation for good reason on December 31, 2014, pursuant to the terms of his employment agreement, 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-competition (12 months), 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.

        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, 2014. Upon a termination without cause or resignation for good reason following a change in control of IAC on December 31, 2014, in accordance with our omnibus stock and annual incentive plans and the related award agreements, the vesting of all then outstanding and unvested IAC stock options and IAC RSUs held by Mr. Kip would have been accelerated.

        For Mr. Kip, "good reason" means actions taken by the Company resulting in a material negative change in the employment relationship, which actions include: (i) a material diminution in the authorities, duties or responsibilities of the reporting officer, (ii) a material reduction in his title, duties

or level of responsibilities (including any circumstances under which the Company is no longer publicly traded and is controlled by another company), (iii) a material reduction in his base salary, (iv) a relocation of his principal place of employment outside of the New York City metropolitan area or (v) any other action or inaction that constitutes a material breach by the Company of his employment agreement, in each case, without the written consent of Mr. Kip or that is not cured promptly after notice.

Mr. Winiarski

        Upon a termination without cause or resignation for good reason on December 31, 2014, 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 IAC stock options and IAC 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 IAC stock options through June 30, 2016.

        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, 2014. Upon a termination without cause or resignation for good reason following a change in control of IAC on December 31, 2014, in accordance with our omnibus stock and annual incentive plans and the related award agreements, the vesting of all then outstanding and unvested IAC stock options and IAC 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.

Equity Compensation Plan Information

        Securities Authorized for Issuance Under Equity Compensation Plans.    The following table summarizes information, as of December 31, 2014, regarding IAC equity compensation plans pursuant to which grants of IAC stock options, IAC RSUs or other rights to acquire shares of IAC common stock may be made from time to time.

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 2014 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 IAC 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 Board service 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.

        2014 Non-Employee Director Compensation.    The table below provides the amount of: (i) fees earned by non-employee directors for services performed during 2014 and (ii) the grant date fair value of IAC RSU awards granted in 2014.

        Section 16(a) of the Exchange Act requires the Company's officers and directors, and persons who beneficially own more than 10% of a registered class of the Company's equity securities, to file initial statements of beneficial ownership (Form 3) and statements of changes in beneficial ownership (Forms 4 and 5) of common stock and other equity securities of the Company with the SEC. Officers, directors and greater than 10% beneficial owners are required by SEC rules to furnish the Company with copies of all such forms they file. Based solely on a review of the copies of such forms furnished to the Company and/or written representations that no additional forms were required, the Company believes that its officers, directors and greater than 10% beneficial owners complied with these filing requirements in 2014.

CERTAIN RELATIONSHIPS AND RELATED PERSON 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 2014, 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. In connection with such determinations, Company management and the Audit Committee consider: (i) the parties to the transaction and the nature of their affiliation with IAC and the related person, (ii) the dollar amount involved in the transaction, (iii) the material terms of the transaction, including whether the terms of the transaction are ordinary course and/or otherwise negotiated at arms' length, (iv) whether the transaction is material, on a quantitative and/or qualitative basis, to IAC and/or the related person and (v) any other facts and circumstances that Company management or the Audit Committee deems appropriate.

Relationships Involving Significant Stockholders, Named Executives and Directors

        Relationships Involving Mr. Diller.    Pursuant to an agreement between Mr. Diller and IAC, certain transfer restrictions apply to 1.5 million shares of IAC Class B common stock acquired by Mr. Diller in 2011, including a requirement that, until December 1, 2015 and except for transfers to certain permitted transferees, these shares must first be converted into IAC common stock in order to be transferred.

        In addition, 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, 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, IAC and Mr. Diller entered into an agreement with respect to the construction of a screening room on Mr. Diller's property to assist Mr. Diller in connection with Company-related activities. Construction costs of approximately $1.8 million were paid by the Company and the agreement provides that under certain circumstances, including upon the termination of Mr. Diller's employment by IAC or its affiliates, Mr. Diller shall have the option to pay to IAC an amount equal to the depreciated book value of the construction costs to acquire the facilities.

        As discussed in the Compensation Discussion and Analysis on page 22, 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 use. Mr. Diller reimbursed IAC approximately $325,000 for personal use of Company-owned aircraft in 2014.

        Relationships Involving Other Directors.    During 2014, an IAC business was billed for data licensing services provided by infoGroup, Inc. ("infoGroup") in the aggregate amount of approximately $450,000. infoGroup is a portfolio company of CCMP Capital Advisors, LLC, of which Mr. Zannino is a Managing Director and member of the firm's Investment Committee. The agreement pursuant to which the IAC business made these payments was entered into by the parties before Mr. Zannino began serving on the Board and before CCMP acquired infoGroup.

        In June 2010, Mr. Bronfman was part of a trial in the Trial Court in Paris involving six other individuals, including the former Chief Executive Officer, Chief Financial Officer and Chief Operating Officer of Vivendi Universal. The other individuals faced various criminal charges and civil claims relating to Vivendi, including Vivendi's financial disclosures, the appropriateness of executive compensation and trading in Vivendi stock. Mr. Bronfman previously served as the Vice Chairman of Vivendi and faced a charge and claims relating to certain trading in Vivendi stock in January 2002. At the trial, the public prosecutor and the lead civil claimant both took the position that Mr. Bronfman should be acquitted. In January 2011, the court found Mr. Bronfman guilty of the charge relating to his trading in Vivendi stock, found him not liable to the civil claimants and imposed a fine of 5 million euros and a suspended sentence of fifteen months. Mr. Bronfman appealed the Trial Court decision to the Paris Court of Appeal. In November 2013, Mr. Bronfman participated in a re-trial before a new judicial panel as part of his appeal of the Paris Trial Court's 2011 ruling. In May 2014, the new judicial panel rendered its decision, affirming the Paris Trial Court's finding that Mr. Bronfman was guilty of the charge, but stated that its finding would appear only in French judicial records (and not in Mr. Bronfman's public record), removed the suspended sentence imposed by the Paris Trial Court and suspended 2.5 million euros of the original fine of 5 million euros. The new judicial panel affirmed the Paris Trial Court's finding that Mr. Bronfman was not liable to the civil claimants. Mr. Bronfman has appealed the verdict and believes that his trading in Vivendi stock was proper. Under French law, the penalty is suspended pending the final outcome of the case.

Relationships Involving IAC and Expedia

        Overview.    Since the completion of the spin-off of Expedia in August 2005 (the "Expedia Spin-Off"), IAC and Expedia have been related parties since they are under common control. In connection with and following the Expedia Spin-Off, IAC and Expedia entered into certain arrangements, including arrangements regarding the sharing of certain costs, the use and ownership of certain aircraft and various commercial agreements, certain of which are generally described below.

        Cost Sharing Arrangements.    Mr. Diller currently serves as Chairman and Senior Executive of both IAC and Expedia. In connection with the Expedia Spin-Off, IAC and Expedia had agreed, in light of Mr. Diller's senior role at both companies and his anticipated use of certain resources to the benefit of both companies, to share certain expenses associated with such usage, as well as certain costs incurred by IAC in connection with the provision of certain benefits to Mr. Diller (the "Shared Costs"). Cost sharing arrangements in effect from 2007 through September 2014 provided that IAC and Expedia cover 65% and 35% of the Shared Costs, respectively, which both companies agreed best reflected the allocation of actual time spent by Mr. Diller between the two companies during this period. Given Mr. Diller's continuing roles at both IAC and Expedia, and based upon a review of the allocation of time spent by Mr. Diller at each of the companies, in September 2014, IAC and Expedia entered into new cost sharing arrangements. These cost sharing arrangements provide that each of IAC and Expedia cover 50% of the Shared Costs, which both companies agreed best reflects the allocation of actual time spent (and time to be spent) by Mr. Diller between the two companies. Shared Costs include costs for personal use of cars and equipment dedicated to Mr. Diller's use and expenses relating to Mr. Diller's support staff. During 2014, IAC billed Expedia for costs in the amount of approximately $381,000 pursuant to these arrangements.

        Aircraft Arrangements.    Each of IAC and Expedia has a 50% ownership interest in two aircraft that are used by both companies (the "Aircraft"). IAC and Expedia entered into an amended and restated operating agreement that allocates the costs of operating and maintaining the Aircraft between the parties. Fixed costs are allocated 50% to each company and variable costs are allocated based on usage. These costs are generally paid by each company to third parties in accordance with the terms of the amended and restated operating agreement.

        In the event Mr. Diller ceases to serve as Chairman of either IAC or Expedia, each of IAC and Expedia will have a put right (to the other party) with respect to its owned interest in the aircraft that it does not primarily use (with such determination to be based on relative usage over the twelve months preceding such event), in each case, at fair market value for the aircraft in question.

        Members of the flight crew for the Aircraft are employed by an entity in which each of IAC and Expedia has a 50% ownership interest. IAC and Expedia have agreed to share costs relating to flight crew compensation and benefits pro rata according to each company's respective usage of the Aircraft, for which they are separately billed by the entity described above. During 2014, total payments in the amount of approximately $1.8 million were made to this entity by IAC.

        Commercial Agreements.    In connection with and following the Expedia Spin-Off, certain IAC businesses entered into commercial agreements with certain Expedia businesses. IAC believes that these arrangements are ordinary course and have been negotiated at arm's length. In addition, IAC believes that none of these arrangements, whether taken individually or in the aggregate, constitute a material contract to IAC. None of these arrangements, whether taken individually or together with similar agreements, involved payments to or from IAC and its businesses in excess of $120,000 in 2014.

ANNUAL REPORTS

        Upon written request to the Corporate Secretary, IAC/InterActiveCorp, 555 West 18th Street, New York, New York 10011, IAC will provide without charge to each person solicited a printed copy of IAC's 2014 Annual Report on Form 10-K, including the financial statements and financial statement schedule filed therewith. Copies are also available on our website, www.iac.com. IAC will furnish requesting stockholders with any exhibit to its 2014 Annual Report on Form 10-K upon payment of a reasonable fee.

PROPOSALS BY STOCKHOLDERS FOR PRESENTATION AT THE 2016 ANNUAL MEETING

        Eligible stockholders who intend to have a proposal considered for inclusion in IAC's proxy materials for presentation at the 2016 Annual Meeting of Stockholders must submit the proposal to IAC at its corporate headquarters no later than January 13, 2016, which proposal must be made in accordance with the provisions of Rule 14a-8 of the Exchange Act. Eligible stockholders who intend to present a proposal at the 2016 Annual Meeting of Stockholders without inclusion of the proposal in IAC's proxy materials are required to provide notice of such proposal to IAC no later than March 28, 2016. IAC reserves the right to reject, rule out of order or take other appropriate action with respect to any proposal that does not comply with these and other applicable requirements.

HOUSEHOLDING

        The SEC has adopted rules that permit companies and intermediaries (such as brokers) to send one Notice or set of printed proxy materials to any household at which two or more stockholders reside if they appear to be members of the same family or have given their written consent (each stockholder continues to receive a separate proxy card). This process, which is commonly referred to as "householding," reduces the number of duplicate copies of materials stockholders receive and reduces printing and mailing costs. Only one copy of the Notice or one set of our printed proxy materials, as applicable, will be sent to stockholders eligible for householding unless contrary instructions have been provided.
