Dear Stockholder:

We are pleased to invite you to the 2015 Annual Meeting of Stockholders to be held on June 24, 2015 at 11:00 a.m. Eastern Time. This year’s Annual Meeting will be a completely virtual meeting of stockholders held over the Internet. You will be able to attend the Annual Meeting, vote your shares electronically and submit your questions during the live webcast of the meeting by visiting www.virtualshareholdermeeting.com/wisdomtree15 and entering your 16-digit control number.

Similar to last year, most of our stockholders will not receive paper copies of our proxy materials and will instead receive a Notice of Internet Availability of Proxy Materials with instructions on how to access our proxy materials and how to vote online or by telephone. Such Notice will also provide information on how to obtain paper copies of our proxy materials if a stockholder so requests. This method expedites the receipt of your proxy materials, lowers the costs of our Annual Meeting and helps to conserve our natural resources.

Every stockholder’s vote is important, so whether or not you are planning to attend the meeting, we encourage you to vote your shares by voting (i) over the Internet or (ii) by telephone, or (iii) by requesting a paper copy of the proxy materials, including a proxy card, and returning an executed proxy card.

We hope that you will join us at the Annual Meeting live webcast on June 24, 2015. I thank you for your commitment to WisdomTree and urge you to vote your shares.

Sincerely,

Jonathan Steinberg

Chief Executive Officer

QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING AND PROXY MATERIALS

Who is soliciting my vote?

The Board of Directors of WisdomTree Investments, Inc. (“WisdomTree” or the “Company”) is soliciting your vote for the 2015 Annual Meeting of Stockholders.

Who pays for the cost of soliciting proxies?

WisdomTree will pay the cost for the solicitation of proxies by the Board of Directors. Proxies may be solicited personally, by telephone, fax or e-mail by employees of WisdomTree without any remuneration to such individuals other than their regular compensation. WisdomTree also will reimburse brokers, banks, custodians, other nominees and fiduciaries for forwarding these materials to their principals to obtain the authorization for the execution of proxies.

Why did I receive a one-page notice in the mail regarding the internet availability of proxy materials instead of a full set of proxy materials?

Pursuant to rules adopted by the Securities and Exchange Commission (“SEC”), the Company has elected to provide access to its proxy materials via the Internet. Accordingly, the Company is sending a Notice of Internet Availability of Proxy Materials (“Notice”) to the Company’s stockholders. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the Internet or to request a printed copy may be found in the Notice. In addition, stockholders may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis. The Company encourages stockholders to take advantage of the availability of the proxy materials on the Internet to help reduce the environmental impact of its annual meetings.

How can I get electronic access to the proxy materials?

The Notice will provide you with instructions regarding how to:

The Company’s proxy materials also are available on the Company’s investor relations website at http://ir.wisdomtree.com by following the link for “Financial Information.”

Choosing to receive future proxy materials by email will save the Company the cost of printing and mailing documents to you and will reduce the impact of the Company’s annual meetings on the environment. If you choose to receive future proxy materials by email, you will receive an email message next year with instructions containing a link to those materials and a link to the proxy voting website. Your election to receive proxy materials by email will remain in effect until you terminate it.

How do I attend the Annual Meeting and may I ask questions?

This year’s Annual Meeting will be a completely virtual meeting of stockholders held over the Internet. Please go to www.virtualshareholdermeeting.com/wisdomtree15 for instructions on how to attend and participate in the Annual Meeting. Any stockholder may attend and listen live to the webcast of the Annual Meeting over the Internet at such site. Stockholders as of the record date of the Annual Meeting may submit questions while attending the Annual Meeting over the Internet by using the 16-digit control number included in the Notice, proxy card or the voting instructions that accompanied these proxy materials.

What is the difference between a stockholder of record and a beneficial owner of shares held in street name?

Stockholder of record. If your shares are registered directly in your name with the Company’s transfer agent (Continental Stock Transfer & Trust Company), you are considered a stockholder of record (or record holder) with respect to those shares, and the Notice was sent directly to you by the Company.

Beneficial owner of shares held in street name. If your shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the “beneficial owner” of shares held in “street name,” and a Notice was forwarded to you by that organization. As a beneficial owner, you have the right to instruct your broker, bank, trustee, or nominee how to vote your shares.

How do I vote my shares?

Whether you are a “stockholder of record” or hold your shares in “street name,” you may vote by proxy prior to the polls closing without participating in the online Annual Meeting. To vote by proxy, stockholders have a choice of voting over the Internet, by telephone or by using a traditional proxy card. Your shares will be voted in accordance with your instructions. If you plan to attend and participate in our online Annual Meeting, we still encourage you to vote prior to the Annual Meeting by telephone or Internet, or by returning a proxy card following your request of printed materials. This will ensure that your vote will be counted if you are unable to, or later decide not to, participate in the online Annual Meeting. You also may vote online at the Annual Meeting prior to the polls closing. You will need to enter your 16-digit control number (included in your Notice, your proxy card or the voting instructions that accompanied your proxy materials) to vote your shares at the Annual Meeting.

Vote by Internet Go to www.proxyvote.com. You will need your 16-digit control number included in your proxy card, voter instruction form or Notice.		Vote by Mobile Phone If you have your proxy card, you can directly scan the QR code on the proxy card with your mobile phone or, if you have the 16-digit control number included in your proxy card, voter instruction form or Notice, you can scan the above QR code.

What are the Board’s recommendations on how to vote my shares?

The Board of Directors recommends a vote:

Can I change my vote?

You may revoke your proxy at any time before it is voted by notifying the Secretary of WisdomTree in writing, by returning a signed proxy with a later date, by transmitting a subsequent vote over the Internet or by telephone prior to the close of the Internet voting facility or the telephone voting facility, or by attending the online meeting, entering your 16-digit control number and voting again electronically at the Annual Meeting.

How many votes can be cast by all stockholders?

137,033,096 shares of the Company’s common stock were outstanding on April 27, 2015 (record date for determining stockholders eligible to vote) and entitled to be voted at the meeting. Each share of common stock is entitled to one vote on each matter.

What percentage of the vote is required for a proposal to be approved?

The three nominees for election as Class I directors who receive a plurality of the votes cast for election of directors shall be elected directors (Proposal 1). A majority of votes cast is necessary for ratification of the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2015 (Proposal 2). A majority of votes cast is necessary for the approval of the advisory resolution on the compensation of the Company’s named executive officers (Proposal 3). If there are insufficient votes to approve Proposal 2, your proxy may be voted by the persons named in the proxy to adjourn the Annual Meeting in order to solicit additional proxies in favor of the approval of such proposal. If the Annual Meeting is adjourned or postponed for any purpose, at any subsequent reconvening of the meeting, your proxy will be voted in the same manner as it would have been voted at the original convening of the Annual Meeting unless you withdraw or revoke your proxy. Your proxy may be voted in this manner even though it may have been voted on the same or any other matter at a previous session of the Annual Meeting.

How is a quorum reached?

The presence, in person or by proxy, of holders of at least a majority of the total number of outstanding shares entitled to vote is necessary to constitute a quorum for the transaction of business at the Annual Meeting. Shares held of record by stockholders or brokers, bankers or other nominees who do not return a signed and dated proxy or attend the online Annual Meeting in person will not be considered present or represented at the Annual Meeting and will not be counted in determining the presence of a quorum. Abstentions and “broker non-votes” (i.e., shares represented at the meeting held by brokers, bankers or other nominees as to which instructions have not been received from the beneficial owners or persons entitled to vote such shares and, with respect to one or more but not all issues, such brokers or nominees do not have discretionary voting power to vote such shares), if any, will be counted for purposes of determining whether a quorum is present for the transaction of business at the meeting.

Table of Contents

How is the vote counted?

Votes cast by proxy or in person at the Annual Meeting will be counted by the person(s) appointed by WisdomTree to act as inspector(s) of election for the meeting. The inspector(s) of election will count all votes “for,” “against,” “withhold,” and abstentions and broker non-votes, as applicable, for each matter to be voted on at the Annual Meeting. Shares represented by proxies that withhold authority to vote for a nominee for election as a director will not be counted as votes “for” a director. Shares properly voted to “abstain” on a particular matter and broker non-votes are treated as having not voted on the particular matter and will therefore not affect the outcome of Proposals 1, 2 and 3.

What does it mean if I receive more than one proxy card or voting instruction form?

It means that you have multiple accounts at the transfer agent or with brokers. Please complete and return all proxy cards or voting instruction forms to ensure that all of your shares are voted.

Could other matters be decided at the Annual Meeting?

WisdomTree does not know of any other matters that may be presented for action at the Annual Meeting. Should any other business come before the meeting, the persons named on the enclosed proxy will have discretionary authority to vote the shares represented by such proxies in accordance with their best judgment. If you hold shares through a broker, bank or other nominee as described above, they will not be able to vote your shares on any other business that comes before the Annual Meeting unless they receive instructions from you with respect to such matters.

What happens if the Annual Meeting is postponed?

Your proxy may be voted at the postponed or adjourned meeting. You will be able to change your proxy until it is voted.

Will the Annual Meeting be webcast?

Yes. This year’s Annual Meeting will be a completely virtual meeting and will be webcast live at www.virtualshareholdermeeting.com/wisdomtree15.

What is the deadline to propose actions for consideration or to nominate individuals to serve as directors at the 2016 Annual Meeting?

Stockholders who wish to present proposals for inclusion in our proxy materials for our 2016 Annual Meeting of Stockholders may do so by following the procedures prescribed in Rule 14a-8 under the Securities Exchange Act of 1934 (“Exchange Act”) and in our by-laws. Our Secretary must receive stockholder proposals intended to be included in our proxy statement and form of proxy relating to our 2016 Annual Meeting of Stockholders made under Rule 14a-8 by December 31, 2015. It is the policy of our Nominating Committee to consider nominations for candidates to our Board of Directors that are properly submitted by our stockholders in accordance with our by-laws. Under our current by-laws, proposals of business and nominations for directors other than those to be included in our proxy materials following the procedures described in Rule 14a-8 may be made by any stockholder who was a stockholder of record at the time of the giving of notice provided for in our by-laws, who is entitled to vote at the meeting, who is present (in person or by proxy) at the meeting and who complies with the notice procedures set forth in our by-laws (i.e., notice must be timely given and contain the information required by the by-laws). To be timely, a notice with respect to the 2016 Annual Meeting of Stockholders must be delivered to our Secretary no earlier than Tuesday, February 24, 2016 and no later than Thursday, March 26, 2016, unless the date of the 2016 Annual Meeting is advanced by more than thirty (30) days or delayed by more than sixty (60) days from the anniversary date of the 2015 Annual Meeting, in which event the by-laws provide

DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE

Board Composition

Our Board of Directors currently consists of eight members. Our certificate of incorporation and by-laws provide that the number of our directors shall be fixed from time to time by a resolution of the majority of our Board of Directors. Pursuant to our by-laws, the Board of Directors has fixed the number of directors at eight as of the date of this year’s Annual Meeting of Stockholders. In accordance with Delaware law and the Company’s certificate of incorporation and by-laws, the Board of Directors is divided into three staggered classes of directors of the same or nearly the same number. At each annual meeting of the stockholders, a class of directors will be elected for a three year term to succeed the directors of the same class whose terms are then expiring. The terms of the directors will expire upon the election and qualification of successor directors at the annual meeting of stockholders to be held in 2015 for Class I directors, 2016 for Class II directors and 2017 for Class III directors. The following directors serve in Class I, II and III:

Any directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class shall consist of one third of the Board of Directors. The division of our Board of Directors into three classes with staggered three-year terms may delay or prevent stockholder efforts to effect a change of our management or a change in control.

Our Nominating Committee and Board of Directors consider a broad range of factors relating to the qualifications and background of nominees. We have no formal policy regarding board diversity. Our Nominating Committee’s and Board of Directors’ priority in selecting board members is identification of persons who will further the interests of our stockholders through his or her established record of professional accomplishment, the ability to contribute positively to the collaborative culture among board members, and professional and personal experiences and expertise relevant to our growth strategy.

Directors

Our Board of Directors is divided into three staggered classes of directors of the same or nearly the same number. At the Annual Meeting, three individuals will be elected to serve as Class I Directors until their term expires in 2018, and until their successors are elected and qualified. During 2014, each of the nominees to the Board served as a Director.

Board Independence

NASDAQ rules require listed companies to have a board of directors with at least a majority of independent directors. Our Board of Directors has determined that six of our eight directors are independent under the listing standards of the NASDAQ Stock Market. The members determined to be independent are Messrs. Begleiter, Bossone, Lilien, Neuger, Salerno and Steinhardt.

Lead Independent Director

In 2008, our Board of Directors determined that it would be good corporate practice to designate one of our independent directors as Lead Independent Director. Mr. Salerno has held this designation since the position was established. The duties of our Lead Independent Director are as follows:

Board Leadership Structure and Board’s Role in Risk Oversight

At present, the Board of Directors has chosen to separate the roles of chairman of the Board of Directors and chief executive officer. Jonathan L. Steinberg is our President and Chief Executive Officer and Michael

12

Table of Contents

Steinhardt is our non-executive Chairman of the Board of Directors. We believe that separating these positions is optimal for WisdomTree at this time because it allows our Mr. Steinberg to focus on our day-to-day business, while allowing Mr. Steinhardt to focus on leadership of the Board of Directors in its fundamental role of providing advice to and independent oversight of management. Our Board of Directors recognizes the time, effort and energy that the chief executive officer is required to devote to his position in the current business environment, as well as the commitment required to serve as our chairman, particularly as the Board of Directors’ oversight responsibilities continue to grow. While our by-laws and corporate governance guidelines do not require that our chairman and chief executive officer positions be separate, our Board of Directors believes that having separate positions is the appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance.

Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. We face a number of risks; including risks relating to our operations, strategic direction and intellectual property as more fully discussed under “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014, as updated from time to time. Management is responsible for the day-to-day management of the risks we face, while our Board of Directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our Board of Directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

The Board of Directors’ role in overseeing the management of our risks is conducted primarily through committees of the Board of Directors, as disclosed in the descriptions of each of the committees below and in the charters of each of the committees. The full Board of Directors (or the appropriate board committee in the case of risks that are under the purview of a particular committee) discusses with management our major risk exposures, their potential impact on our Company and the steps we take to manage them. When a board committee is responsible for evaluating and overseeing the management of a particular risk or risks, the chairman of the relevant committee reports on the discussion to the full Board of Directors during the committee reports portion of the next board meeting. This enables our Board of Directors and its committees to coordinate the risk oversight role, particularly with respect to risk interrelationships.

Committees of Our Board of Directors

Our Board of Directors has established an Audit Committee, a Compensation Committee and a Nominating Committee, each of which operates pursuant to a charter adopted by our Board of Directors. Membership on each committee is limited to independent directors as defined under the listing standards of the NASDAQ Stock Market. In addition, members of the Audit Committee must also meet the independence standards for Audit Committee members adopted by the SEC. Our Board of Directors may from time to time establish other committees. Charters for each of the Audit Committee, Compensation Committee and Nominating Committee are available on our website at http://ir.wisdomtree.com by following the link for “Corporate Governance,” under the heading “Committee Charters.”

Audit Committee

Messrs. Bossone, Lilien and Salerno currently serve on the Audit Committee, which is chaired by Mr. Salerno. Our Board of Directors has determined that each member is an “audit committee financial expert,” as defined under the applicable rules of the SEC. The Audit Committee’s responsibilities include:

None of the members of the Compensation Committee has been an officer of the Company and none were employees of the Company during 2014 and, other than Mr. Steinhardt, none had any relationship with the Company or any of its subsidiaries during 2014 that would be required to be disclosed as a transaction with a related person.

None of the executive officers of the Company has served on the board of directors or compensation committee of another company (or other board committee performing equivalent functions) at any time during which an executive officer of such other company served on the Company’s Board of Directors or the Compensation Committee.

Compensation Committee Report

The following report of the Compensation Committee shall not be deemed to be “soliciting material” or to otherwise be considered “filed” with the SEC, nor shall such information be incorporated by reference into any future filing under the Securities Act or the Exchange Act except to the extent that the Company specifically incorporates it by reference into such filing.

The Compensation Committee of the Board of Directors of WisdomTree has reviewed and discussed with management the information contained in the Compensation Discussion and Analysis section of this proxy statement for the fiscal year ended December 31, 2014. Based upon that review and discussion, the Compensation Committee has recommended to the Board of Directors that the information set forth below under the heading “Compensation Discussion and Analysis” be included in this proxy statement.

Compensation Committee

Compensation Discussion and Analysis

Overview

This Compensation Discussion and Analysis provides comprehensive information regarding our compensation programs and policies for our following named executive officers:

We believe we provide a competitive total compensation opportunity for our executive management team through a combination of base salary, cash incentive bonuses, equity compensation and broad-based benefits programs. This Compensation Discussion and Analysis explains the following:

Executive Summary

2014 was a year of challenges and successes relevant to the key business metrics used to measure compensation of our named executive officers. Despite negative investor sentiment towards emerging markets, we generated $5.1 billion of net inflows into our U.S. listed ETFs, our U.S. listed AUM increased 12.6% to a record $39.3 billion, and our U.S. market share of industry inflows was 2.1%. These operating results translated into record financial results with total revenues increasing 22.9% to $183.8 million in 2014 and pretax income increasing 42.7% to $73.5 million. Our pretax margin increased from 34.5% to 40.0%. Our AUM concentration

in Japan and emerging markets contributed to our stock price decline of 12% in 2014 and we ranked 14^th of the 19 publicly traded asset managers in the U.S.; yet we continued to have the fastest organic growth rate of this peer group.

We continued to make investments to focus on growth and our long term success. We expanded our product offering with the launch of nine new U.S. listed ETFs in 2014. We successfully transitioned our fund accounting, administrative and custody services to State Street Bank and Trust Company yielding enhanced capabilities and improvements to our gross margin. We closed our acquisition of Boost ETP, or Boost, and launched six WisdomTree branded UCITS ETFs in Europe within six months of closing. Through state tax planning, we lowered our U.S. tax rate to approximately 38% from 45%. To prepare for expansion to help support our growth, we moved into new office space without experiencing any disruptions to our operations. Lastly, we strengthened our team with the net addition of 14 employees in the U.S. across all business functions.

Overall, the performance of the executive team and employees of WisdomTree met the Compensation Committee’s expectations. Based on these overall results, the Compensation Committee approved a total incentive compensation pool that was approximately 88% of the targeted amount in accordance with our performance based incentive plan which is discussed further below.

Our Compensation Philosophy and Objectives

Our compensation philosophy and objectives are primarily shaped by strategies targeted to achieve our long-term goals within the business environment in which we operate. We operate in an intensively competitive and challenging business environment and we expect competition to continue and intensify. We directly compete with numerous other ETF sponsors and indirectly compete with other larger and multi-national traditional asset management companies. We compete on a number of factors including the breadth and depth of our product offering as well as the investment performance and fees of our ETFs. We believe our long-term success depends on our ability to continue to:

The primary objectives of our compensation program are as follows:

The following principles guide our compensation programs:

17

Table of Contents

We believe we have designed our competitive compensation packages to incorporate the above principles and ensure that our executive compensation is aligned with corporate strategies and business objectives.

Components of Compensation

We have established the following components of compensation to satisfy our compensation objectives:

We believe these components provide competitive compensation packages recognizing and rewarding individual contributions; ensure that executive compensation is aligned with corporate strategies and business objectives; and promote the achievement of key strategic and operating performance measures.

Base Salary – We use base salary as a means of providing steady pay or a fixed source of compensation for our executive officers allowing them a degree of certainty in order to attract and retain them. Our Compensation Committee believes the majority of our executives’ compensation should be earned through incentive compensation and therefore, keeps base salary at a fixed level year over year, similar to other companies in the financial services industry.

18

Table of Contents

Annual Incentive Compensation – Incentive compensation is awarded in cash and is used to motivate and reward our employees for achieving certain short-term operating, financial and other business goals.

Long-Term Equity Compensation – Because short-term performance does not by itself accurately reflect our overall performance nor the return realized by our stockholders, we offer our employees equity awards as a long-term incentive. We believe that providing equity ownership:

In determining the appropriate mix of short-term and long-term incentive compensation to our executives, and all our employees, our Compensation Committee and management believe that employees with higher authority, responsibility and ability to significantly influence our growth and profitability, should receive their incentive compensation more weighted towards long term equity to align their interest with our long term success. As a result, our CEO’s incentive compensation is more heavily weighted to long term equity incentives, followed by our other executive officers.

Benefits and Perquisites – As stated in our compensation philosophy, our executive officers and Compensation Committee agree that perquisites should be rare and limited to those that are important to our employees’ ability to safely and effectively carry out their responsibilities. Our executive officers are entitled to participate in directors’ and officers’ liability insurance, as well as the various benefits made available to our other employees, such as our group health plans, paid vacation and sick leave, basic life insurance, short and long-term disability benefits and 401(k) plan with contribution matching up to 50%.

Severance – Pursuant to employment agreements that we have entered into with our CFO and CLO, each of them is entitled to specified benefits in the event of termination of his employment under certain conditions, including partial acceleration of unvested restricted stock and guaranteed minimum severance payments and benefits. Our COO also was entitled to such benefits pursuant to his employment agreement prior to December 31, 2014. We anticipate entering into new employment agreements with all of our executive officers prior to the Annual Meeting which will entitle each of them to specified benefits in the event of the involuntary termination of his employment without cause or the voluntary termination of his employment for good reason. These benefits are described under “2015 Fiscal Year Employment Agreements.”

Change-in-Control Benefits – Upon a change in control that occurs during the employment of our executive officers or, in certain circumstances, within 12 months following the executive’s involuntary termination without cause or voluntary termination for good reason, certain of the equity awards that have been granted to our named executive officers will accelerate (stock options will become fully or partially vested and the conditions and restrictions on any restricted stock awards will be removed). We have provided more detailed information about these benefits, along with estimates of value under various circumstances, in the table below under “Potential Payments Upon Termination or Change of Control.” The new employment agreements which we anticipate will be executed prior to the Annual Meeting with our named executive officers will provide for specified benefits in the event of a change in control, which are described under “2015 Fiscal Year Employment Agreements.”

Our goal in providing severance and change in control benefits is to offer sufficient certainty in compensation such that our executive officers will focus their full time and attention on the requirements of the business rather than the potential implications for their respective positions. We believe these benefits assist in maintaining a competitive position in terms of attracting and retaining key executives which is in the best interests of our stockholders.

Role of the Compensation Committee, Performance Evaluations and Management

The Compensation Committee, which is comprised entirely of independent directors, is responsible for the general oversight of our compensation policies and practices. The Compensation Committee also reviews the overall compensation structure and evaluates the overall performance of our executive officers in order to determine that compensation is fair, reasonable, competitive and consistent with our compensation philosophies and objectives based on their collective experiences and business judgment. The Compensation Committee engages an independent compensation consultant with respect to executive compensation.

The Compensation Committee specifically evaluates the performance of our CEO and, with input from our CEO, the overall performance of our other executive officers. The Compensation Committee also discusses the overall performance and compensation of our executives with members of our Board of Directors and presents them with information regarding compensation matters throughout the year as needed.

The Compensation Committee oversees the development, implementation and administration of our compensation programs, including all compensation plans adopted by the Board under which equity grants are made, determines and approves performance measures and goals and objectives relevant to the compensation program, evaluates the performance of the CEO in light of those goals and objectives, and determines and approves the CEO’s compensation based on this evaluation, reviews and approves the compensation of the non-CEO executive officers, reviews and approves all discretionary bonuses to our employees, and reviews and approves employment, severance, and change in control agreements as well as any other supplemental benefits provided to our executive officers and other senior employees under the Committee’s purview. The Compensation Committee also reviews and makes recommendations to our Board of Directors with respect to directors’ compensation. The Compensation Committee also works with our CLO to annually review and reassess the adequacy of its charter, proposing changes as necessary to our Board of Directors for approval.

Our management and executive officers play a critical and important role in setting or recommending compensation levels throughout our organization. Our CEO makes incentive compensation recommendations to the Compensation Committee for the executive officers other than the CEO. In considering the CEO’s recommendations, the Compensation Committee evaluates results measured by the performance measures, goals and objectives of our compensation programs as well as qualitative factors to ensure that compensation is fair, reasonable, competitive and consistent with our compensation philosophies and objectives.

Management works with the Compensation Committee to design and develop compensation programs applicable to all our employees, including recommending changes to existing compensation programs and operational performance targets, preparing analyses of Company financial, operational data or other Compensation Committee briefing materials, analyzing industry data, and, ultimately, implementing the decisions of the Compensation Committee.

Use of Compensation Consultant

The Compensation Committee has retained Frederic W. Cook & Co., a compensation consultant, to provide objective advice on the pay practices, compensation plan design and the competitive landscape for compensation. WisdomTree pays the cost for Frederic W. Cook’s services. However, the Compensation Committee retains the sole authority to direct, terminate or continue Frederic W. Cook & Co.’s services. The compensation consultant also reviews and makes recommendations for the selection process and pay information used for market compensation benchmarking discussed below. The Compensation Committee has confirmed the independence of Frederic W. Cook & Co. in accordance with SEC and NASDAQ rules.

Market Compensation Benchmarking

The Compensation Committee monitors relevant market and industry statistics on executive compensation as one of several factors it considers in determining compensation to our executive officers. In making compensation decisions, the Compensation Committee reviews:

Industry surveys – McLagan Partners, Inc., a compensation consulting firm for the financial services industry, prepares annual comprehensive compensation surveys for the asset management industry. These surveys consist of consolidated average compensation information of publicly traded and private asset management firms.

Industry peers – Publicly disclosed pay information for certain publicly traded asset management firms that are generally similar in size, market capitalization, product offering or financial metrics as WisdomTree.

The Compensation Committee uses this information for compensation decisions to understand evolving pay trends at asset managers; however, the Compensation Committee recognizes that there are inherent limitations on the comparability and usefulness of the market data, including time lags, differences in scope of responsibilities, geographic differences and other factors. While the Compensation Committee believes such comparative information is useful, such data is intended solely to serve as a reference point to assist the Compensation Committee in its discussions and deliberations.

The Compensation Committee, working with its compensation consultant, reviews the appropriateness of the companies included in the industry peer group twice a year – first, at the beginning of the year, when determining the target pool, and second, at the end of the year, when determining year end compensation. The Committee will adjust the peer group based on relevant metric changes. The 2014 peer group and changes from the 2013 peer group are noted below. Peer group changes were primarily due to better aligning peer companies with our relevant business metrics, including size of AUM:

Consideration of Results of Say-on-Pay Vote

Beginning with our 2012 Annual Meeting of stockholders, and once every three years thereafter, we provide our stockholders with the opportunity to cast an advisory vote on compensation paid to our named executive officers, or say-on-pay. At the 2012 Annual Meeting of stockholders, 78% of our stockholders voting on say-on-pay cast a vote in favor of the proposal. The Compensation Committee reviews the outcome of our stockholders’ advisory say-on-pay proposal in its evaluation and determination of executive compensation. The Compensation Committee considered the results of the stockholders’ advisory vote at our 2012 Annual Meeting, and did not make any changes to our executive compensation policies and decisions as a result of such vote. At this Annual Meeting, we are providing our stockholders with the opportunity to cast an advisory vote on our fiscal year 2014 compensation paid to our named executive officers. The Compensation Committee intends to review the outcome of this say-on-pay proposal in its evaluation and determination of executive compensation for fiscal year 2015.

2014 Incentive Compensation Program

The Compensation Committee together with its independent compensation consultant and management created a formal performance-based incentive compensation program for 2014. This program was designed to determine the proper level of funding for WisdomTree’s total incentive compensation pool relative to achieving certain quantitative metrics and qualitative results that incentivize growth. The achievement of quantitative metrics comprises 50% of the Company’s total incentive compensation pool with the remaining 50% at the discretion and judgment of the Compensation Committee based on qualitative results. This split reflects the Compensation Committee’s desire for a more formulaic bonus plan while recognizing the need to apply some level of judgment in setting appropriate compensation levels to reflect the accomplishment of strategic objectives and individual performance. The quantitative metrics chosen are important measurements that our Board of Directors and investors use to measure the health of our business and relative success. The “median” column represents the payout for reaching median performance metrics. Management focuses on achieving greater than median performance as reflected in the “target” column below. Funding for the quantitative performance portion of the pool is between 0% and 200% of the median payout. The Compensation Committee can fund between 0% and 200% of the discretionary portion of the pool but intends in most years to target between 50% and 150% of median.

The targets, payouts and actual results for 2014 are as follows:

The bonus payout for reaching the quantitative metrics was 76% of the target amount reflecting the underperformance in three of the four performance metrics. The Compensation Committee awarded 100% of the discretionary target amount due to the qualitative factors noted above. In the aggregate, 61% of the total incentive compensation pool was granted as short-term incentive compensation (i.e., cash) with the remaining 39% granted as long-term incentive compensation (i.e., equity). As discussed above, our executive officers received a greater proportion of their total incentive compensation as long-term incentive.

2014 Compensation Results

In determining the amount of incentive compensation and total compensation for our named executive officers, our CEO and Compensation Committee used their business judgment and considered:

The table below reflects the total compensation granted to our named executive officers in a manner that the Compensation Committee used to evaluate total compensation. This table supplements the “Summary Compensation Table” presented below, which is in a different format as required by the SEC:

Long-term equity awards were granted in January 2015 and represent restricted stock which will vest equally over three years commencing on the first anniversary of the grant date. The values for the long-term equity awards represent the accounting grant date fair values in accordance with U.S. generally accepted accounting principles.

The following pie charts reflect the compensation elements of total compensation for our executive officers as a percentage of their total compensation:

Risk Analysis of Compensation Policies and Programs

The Compensation Committee has reviewed our overall compensation policies and believes that these policies do not encourage excessive and unnecessary risk-taking and that the level of risk that they do encourage is not reasonably likely to have a material adverse effect on our Company. The design of the compensation policies and programs encourages employees to remain focused on both our short- and long-term goals. For example, while the cash bonus plan measures performance on an annual basis, the equity awards typically vest over a number of years, which we believe encourages employees to focus on sustained stock price appreciation, thus limiting the potential for excessive risk-taking.

Tax and Accounting Considerations

We evaluate the effect of accounting and tax treatment of particular forms of compensation on an ongoing basis and make appropriate modifications to compensation policies where appropriate. In 2014, our Board of Directors and stockholders approved the 2014 Annual Incentive Compensation Plan (“2014 Plan”), which is intended to meet the requirements of Section 162(m) of the Internal Revenue Code of 1986, as amended (“Code”). Section 162(m) of the Code generally disallows a tax deduction to a publicly-traded company for certain compensation in excess of $1,000,000 paid in any taxable year to the chief executive officer and the three other most highly compensated executive officers (other than the chief financial officer). Qualifying performance-based compensation is not subject to the deduction limitation if specified requirements are met. We believe we have structured the 2014 Plan to comply with exemptions in Section 162(m) so that the compensation payable under the 2014 Plan remains tax-deductible to us. The Compensation Committee in its judgment may, however, authorize compensation payments that do not comply with the exemptions in Section 162(m) when it believes that such payments are appropriate to attract and retain executive talent.

Employment Agreements

We have employment agreements with our COO, CFO and CLO which establish minimum base salary and cash incentive compensation, severance, change in control, certain post-employment restrictive covenants and other benefits. The compensation paid to our COO, CFO and CLO in 2014 was governed by such employment agreements, which are described below under “2014 Fiscal Year Employment Agreements.” We do not maintain employment agreements with our CEO or CIS.

In 2013, the Compensation Committee began discussions with management to make certain changes to their employment agreements to become more aligned with industry best practices. These changes included:

The Compensation Committee worked with its independent consultant and management to negotiate these changes and we anticipate that prior to the Annual Meeting we will enter into employment agreements with our CEO and CIS and enter into new agreements with our COO, CFO and CLO. The terms of these employment

24

Table of Contents

agreements are described below under “2015 Fiscal Year Employment Agreements.” The Compensation Committee believes it is appropriate to maintain these agreements and benefits in order to provide certainty to our executive officers to support a stable executive management team focusing on our long-term success.

Conclusion

After careful review and analysis, we believe that each element of compensation and the total compensation provided to our executive officers is reasonable and appropriate. The Compensation Committee believes that our compensation program gives our executives appropriate incentive to contribute to our long-term performance and believes that our compensation structure and practices encourage management to work as a team in an entrepreneurial culture for outstanding stockholder returns, without taking unnecessary or excessive risks. We believe the total compensation opportunities of our compensation packages will allow us to attract and retain talented executives who have helped and who will continue to help us grow as we look to the years ahead.

2014 Fiscal Year Employment Agreements

The compensation paid to our COO, CFO and CLO in 2014 was governed by the respective employment agreement of such executive officer with the Company. We did not maintain employment agreements with our CEO or CIS in 2014. The following describes the agreements which were in place with our COO, CFO and CLO in 2014. It is anticipated that we will enter into new agreements with our COO, CFO and CLO as well as entering into agreements with our CEO and CIS, before our Annual Meeting, as described below under “2015 Fiscal Year Employment Agreements.”

Gregory Barton

The employment agreement with our COO, Gregory Barton, is for an indefinite term, and on an “at will” basis. Mr. Barton’s agreement provides for a base salary of $300,000. The agreement entitles Mr. Barton to a

28

Table of Contents

guaranteed minimum annual cash bonus of $200,000. The agreement also entitles Mr. Barton to participate in any annual incentive plan established by our Board of Directors or our Compensation Committee and to participate in standard Company benefit plans. The agreement also contains employee confidentiality, assignment of inventions and non-solicitation of employee provisions. Mr. Barton would have been entitled to the same benefits as Messrs. Muni and Ziemba described below in the event of the involuntary termination of his employment without cause or the voluntary termination of his employment for good reason prior to December 31, 2014.

Amit Muni

The employment agreement with our CFO, Amit Muni, is for an indefinite term, and on an “at will” basis. Mr. Muni’s agreement provides for a base salary of $300,000. The agreement entitles Mr. Muni to a guaranteed minimum annual cash bonus of $200,000. The agreement also entitles Mr. Muni to participate in any annual incentive plan established by our Board of Directors or our Compensation Committee and to participate in standard Company benefit plans. The agreement also contains employee confidentiality, assignment of inventions provisions and non-solicitation of employee provisions. Mr. Muni is entitled to certain benefits in the event of the involuntary termination of his employment without cause or the voluntary termination of his employment for good reason. Upon a termination under these circumstances, we agreed to pay Mr. Muni, in addition to all accrued but unpaid base salary and guaranteed minimum annual cash bonus and any discretionary bonus that has been awarded but not yet paid, a severance amount equal to the sum of one-year’s base salary and guaranteed minimum bonus and a prorated guaranteed minimum bonus for the year in which the termination occurs. Mr. Muni may also elect to have us pay for COBRA insurance coverage for a one-year period following his termination.

Peter Ziemba

The employment agreement with our CLO, Peter Ziemba, is for an indefinite term on an “at will” basis. Mr. Ziemba’s agreement provides for a base salary of $300,000. The agreement entitles Mr. Ziemba to a guaranteed minimum annual cash bonus of $200,000. The agreement also entitles Mr. Ziemba to participate in any annual incentive plan established by our Board of Directors or our Compensation Committee and to participate in standard Company benefit plans. The agreement also contains employee confidentiality, assignment of inventions and non-solicitation of employee provisions. Mr. Ziemba is entitled to certain benefits in the event of the involuntary termination of his employment without cause or the voluntary termination of his employment for good reason. Upon a termination under these circumstances, we agreed to pay Mr. Ziemba, in addition to all accrued but unpaid base salary and guaranteed minimum annual cash bonus and any discretionary bonus that has been awarded but not yet paid, a severance amount equal to the sum of one-year’s base salary and guaranteed bonus and a prorated guaranteed minimum bonus for the year in which the termination occurs. Mr. Ziemba may also elect to have us pay for COBRA insurance coverage for a one-year period following his termination.

2015 Fiscal Year Employment Agreements

We anticipate that prior to the Annual Meeting we will enter into employment agreements with our CEO and CIS and enter into new agreements with our COO, CFO and CLO. The terms of the new agreements with our COO, CFO and CLO will be changed to reflect new severance terms. The terms of the agreements for all of the five named executive officers will be substantially identical except that the base salary payable to each executive officer, other than the CEO, will be $300,000, with the CEO receiving a base salary of $450,000. The agreements will not provide for any minimum guaranteed bonus. The agreements will provide that if the executive is terminated by the Company without cause or if the executive resigns for good reason, the Company will pay the executive:

29

Table of Contents

In addition, the vesting of certain equity awards granted to the executive would be accelerated.

In the event that the executive is terminated without cause or voluntarily resigns for good reason, within 18 months after a change of control of the Company, the Company will pay the executive:

In consideration for severance in this circumstance, the executive will be subject to a one-year restrictive covenant. In addition, the vesting of certain equity awards granted to the executive would be accelerated.

If the executive voluntarily resigns without good reason or is terminated for cause, the Company may elect to enforce a three-month restrictive covenant in consideration for which the Company will pay the executive (i) three months’ salary, (ii) an amount equal to 12.5% of the three year average of executive’s incentive compensation, and (iii) an amount equal to 25% of the value of any equity awards that would have vested in the one year following termination if no termination had occurred.

Potential Payments upon Termination or Change of Control

Our named executive officers are entitled to additional compensation in the event of the involuntary termination of their employment without cause, the voluntary termination of their employment for good reason or a change in control. This section is intended to discuss these post-employment payments, assuming the termination from employment or change in control, as the case may be, occurred on December 31, 2014, on the terms currently in effect between the named executive officers and us. Due to the number of factors that affect the nature and amount of any benefits provided upon the events discussed in this section, any actual amounts paid or distributed may be different. Factors that could affect these amounts include the timing during the year of any such event and our stock price. None of our named executive officers are entitled to any compensation in the event of a voluntary termination without good reason or an involuntary termination for cause, other than salary through termination and the unpaid cash portion of the prior year’s incentive compensation.

30

Table of Contents

As described above under the heading “2015 Fiscal Year Employment Agreements,” we anticipate that we will enter into new agreements with our five named executive officers. These agreements will provide for different payments upon termination of employment or a change of control as described above.

Severance Arrangements

Pursuant to the terms of their current employment agreements, each of Messrs. Muni and Ziemba are entitled to certain benefits in the event of the involuntary termination of his employment without cause (as defined in the applicable agreement) or the voluntary termination of his employment for good reason (as defined in the applicable agreement). Under these circumstances, we will pay each of Messrs. Muni and Ziemba, in addition to all accrued but unpaid base salary, the guaranteed minimum annual cash bonus and any discretionary

31

Table of Contents

bonus that has been awarded but not yet paid, an amount equal to the sum of one-year’s base salary and guaranteed minimum annual cash bonus and a pro-rated guaranteed minimum bonus amount for the year in which termination occurred. Each of Messrs. Muni and Ziemba may also elect to have us pay for COBRA insurance coverage for a one-year period following his termination. Pursuant to these severance arrangements and assuming a termination or resignation date of December 31, 2014, Messrs. Muni and Ziemba would have each received incremental values of $723,900. Mr. Barton’s current employment agreement contains the same severance arrangement as Messrs. Muni and Ziemba, which was applicable prior to December 31, 2014, and Messrs. Steinberg and Siracusano were not party to employment agreements in 2014. As a result, assuming the date of termination or resignation was on December 31, 2014, Messrs. Barton, Steinberg and Siracusano each would have received incremental values of $0. It is anticipated that each of Messrs. Steinberg, Barton, Muni, Siracusano and Ziemba will enter into employment agreements with us in 2015 that include the severance arrangements as described under “2015 Fiscal Year Employment Agreements” above.

Acceleration of Options

Certain of the stock options we have granted to Messrs. Steinberg, Muni, Siracusano and Ziemba provide that, upon a change of control (as defined in the applicable agreement) each such stock option will fully vest. As a result, assuming a change of control had occurred on December 31, 2014, Messrs. Steinberg, Muni, Siracusano and Ziemba would have received incremental values of $0, $1,195,313, $0 and $0, respectively.

In addition, certain of the stock options we have granted to each of Messrs. Muni and Ziemba provide that in the event of the involuntary termination of his employment without cause (as defined in the applicable agreement) or the voluntary termination of his employment for good reason (as defined in the applicable agreement), the portion of such stock option that would have otherwise vested during the one year period immediately following the date of termination will vest. As a result, assuming the date of termination or resignation was on December 31, 2014, Messrs. Muni and Ziemba would have received incremental values of $398,438 and $0, respectively.

Acceleration of Restricted Stock

Certain of the restricted stock awards we have granted to each of Messrs. Steinberg, Barton, Muni, Siracusano and Ziemba provide that, upon a change of control (as defined in the applicable agreement), the conditions and restrictions on any restricted stock award will be removed. As a result, assuming a change of control had occurred on December 31, 2014, Messrs. Steinberg, Barton, Muni, Siracusano and Ziemba would have received incremental values of $4,799,026, $2,470,537, $2,524,177, $1,818,003 and $2,484,456, respectively.

Certain of the restricted stock awards we have granted to each of Messrs. Barton, Muni and Ziemba provide that, upon the involuntary termination of his employment without cause (as defined in the applicable agreement) or the voluntary termination of his employment for good reason (as defined in the applicable agreement), the conditions and restrictions on any restricted stock award that would have been removed within the twelve month period that immediately follows the date of termination will be removed immediately. As a result, assuming such termination occurred on December 31, 2014, Messrs. Barton, Muni, and Ziemba would have received incremental values of $310,898, $1,345,652 and $1,359,336, respectively.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS

Stock Ownership Table

The following table sets forth information regarding the beneficial ownership of shares of our common stock as of April 27, 2015 (except as otherwise indicated in the footnotes) by (i) each person (including any “group” of persons as that term is used in Section 13d-3 of the Exchange Act) we know to be the beneficial owner of more than 5% of the outstanding shares of our common stock; (ii) each of our named executive officers; (iii) each of our directors and director-nominees; and (iv) all of our directors and executive officers as a group.

Beneficial ownership is determined in accordance with Rule 13d-3 under the Exchange Act. Except as otherwise indicated in the footnotes to the following table, we believe, based on the information provided to us, that the persons named in the following table have sole vesting and investment power with respect to the shares they beneficially own, subject to applicable community property laws. Unless otherwise noted, the business address of each of the persons and entities that beneficially own 5% or more of the outstanding shares of common stock is c/o WisdomTree Investments, Inc., 245 Park Avenue, 35^th Floor, New York, NY 10167. We have based our calculation of the percentage of beneficial ownership on 137,033,096 shares of our common stock outstanding as of April 27, 2015, including shares of restricted stock issued to our employees but not yet vested.

In computing the number of shares beneficially owned by a person and the percentage ownership of that person, we have included the shares the person has the right to acquire within 60 days of the date above, including through the exercise of any option, warrant or other right or conversion of any security. The shares that a stockholder has the right to acquire within 60 days, however, are not included in the computation of the percentage ownership of any other stockholder.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our executive officers, directors and ten percent stockholders to file reports of ownership and changes in ownership with the SEC. The same persons are required to furnish us with copies of all Section 16(a) forms they file. Based solely on our review of such forms furnished to us during the most recent fiscal year, we believe that all of our executive officers, directors and ten percent stockholders complied with the applicable filing requirements.

AUDIT COMMITTEE REPORT

The Audit Committee of the Board of Directors has reviewed the Company’s audited financial statements for the fiscal year ended December 31, 2014 and has discussed these statements with management and Ernst & Young LLP, the Company’s independent registered public accounting firm. The Company’s management is responsible for the preparation of the Company’s financial statements and for maintaining an adequate system of disclosure controls and procedures and internal control over financial reporting for that purpose. Ernst & Young LLP is responsible for expressing an opinion on the conformity of the audited financial statements with generally accepted accounting principles, their judgments as to the quality, not just the acceptability, of the Company’s accounting principles and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards. The Audit Committee is responsible for providing independent, objective oversight of the Company’s accounting functions and internal controls.

The Audit Committee also received from, and discussed with, Ernst & Young LLP the written disclosures and other communications required to under Public Company Accounting Oversight Board (“PCAOB”) Auditing Standards No. 16, “Communications with Audit Committees,” including among other things, the following:

Ernst & Young LLP also provided the Audit Committee with the written disclosures and the letter required by Rule 3526 of the PCAOB. PCAOB Rule 3526 requires independent registered public accounting firms annually to disclose in writing all relationships that in their professional opinion may reasonably be thought to bear on independence, to confirm their perceived independence and engage in a discussion of independence. The Audit Committee has reviewed this disclosure and has discussed with Ernst & Young LLP their independence from the Company.

Based on its discussions with management and our independent registered public accounting firm, and its review of the representations and information provided by management and our independent registered public accounting firm, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014 for filing with the Securities and Exchange Commission.

No portion of this Audit Committee Report shall be deemed to be incorporated by reference into any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Securities Exchange Act of 1934, as amended (the “Exchange Act”), through any general statement incorporating by reference in its entirety the proxy statement in which this Report appears, except to the extent that the Company specifically incorporates this report or a portion of it by reference. In addition, this report shall not be deemed to be “soliciting material” or to be “filed” under either the Securities Act or the Exchange Act.

OVERVIEW OF PROPOSALS

This Proxy Statement contains three proposals requiring stockholder action. Proposal No. 1 requests the election of three directors to the Board. Proposal No. 2 requests the ratification of the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2015. Proposal No. 3 requests a vote on an advisory resolution to approve the compensation of the Company’s named executive officers. Each proposal is discussed in more detail below.

PROPOSAL 1

ELECTION OF DIRECTORS

Nominees

The Nominating Committee recommended, and the Board of Directors nominated

as nominees to stand for re-election as Class I directors for a three year term until the 2018 Annual Meeting and until his successor is duly elected and qualified.

Unless otherwise instructed, the persons appointed in the accompanying form of proxy will vote the proxies received by them for these nominees, who are all presently directors of WisdomTree. WisdomTree has no reason to believe that any nominee will be unavailable for election at the Annual Meeting. In the event that any of the nominees are unexpectedly not available to serve, proxies may be voted for another person nominated as a substitute by the Board of Directors. The term of office of each person elected as a director will continue until the 2018 annual meeting or until a successor has been elected and qualified, or until the director’s earlier death, resignation, or removal.

The section titled “Directors” commencing on page 7 of this proxy statement contains information about the nominees’ leadership skills and other experiences that caused the Nominating Committee and the Board of Directors to determine that these nominees should serve as directors of WisdomTree.

Required Vote

The affirmative vote of a plurality of the votes cast at the meeting will be required for the election of the Class I director nominees. Broker non-votes and votes withheld will not be treated as votes cast for this purpose and, therefore, will not affect the outcome of the election.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE ELECTION TO THE BOARD OF DIRECTORS OF EACH OF THE ABOVEMENTIONED NOMINEES

PROPOSAL 2

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has appointed Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2015. Ernst & Young LLP acted as the Company’s independent registered public accounting firm for the Company for the year ended December 31, 2014. A representative of Ernst & Young LLP is expected to be present at the Annual Meeting with the opportunity to make a statement if he or she desires and to respond to appropriate questions.

The Company’s organizational documents do not require that the stockholders ratify the selection of Ernst & Young LLP as the Company’s independent registered public accounting firm. The Company requests such ratification as a matter of good corporate practice. A majority of the votes properly cast is required for the approval of the ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm, and brokers, bankers and other nominees have discretionary voting power on this routine matter. Accordingly, abstentions and broker non-votes will have no effect on the ratification. If the stockholders do not ratify the selection, the Audit Committee will reconsider whether to retain Ernst & Young LLP, but still may retain them. Even if the selection is ratified, the Audit Committee, in its discretion, may change the appointment at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.

Principal Accounting Fees and Services

The following table sets forth the fees paid or accrued by us for the audit and other services provided by Ernst & Young LLP during the years ended December 31, 2014 and 2013 (in thousands):

Audit Committee Pre-Approval Policies and Procedures

The Audit Committee pre-approves each audit and non-audit service rendered by Ernst & Young LLP to the Company, including the fees and terms thereof. The Committee may form and delegate authority to subcommittees of the Committee consisting of one or more members when appropriate, including the authority to grant pre-approvals of audit and permitted non-audit services, provided that decisions of such subcommittee to grant pre-approvals shall be presented to the full Committee at its next scheduled meeting pursuant to the Audit Committee Charter. In accordance with this policy, the Audit Committee pre-approved all Audit and Audit-Related fees described above before services were rendered.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

PROPOSAL 3

VOTE ON AN ADVISORY RESOLUTION TO APPROVE THE COMPENSATION OF

THE COMPANY’S NAMED EXECUTIVE OFFICERS

The Board of Directors is committed to excellence in governance. As part of that commitment, and as required by Section 14A(a)(1) of the Exchange Act, the Board of Directors is providing the Company’s stockholders with an opportunity to vote on an advisory resolution related to the compensation of the Company’s named executive officers.

As described above under “Executive Compensation—Compensation Discussion and Analysis,” we have developed a compensation policy that is designed to attract and retain key executives responsible for our success and motivate management to enhance long-term stockholder value. We believe our compensation policy strikes an appropriate balance between the implementation of responsible, measured compensation practices and the effective provision of incentives for our named executive officers to exert their best efforts for our success.

For the reasons discussed above, the Board of Directors unanimously recommends that stockholders vote “FOR” the following resolution:

“RESOLVED, that the Company’s stockholders hereby approve, on an advisory basis, the compensation of the named executive officers, as disclosed in the Company’s proxy statement for the 2015 annual meeting of stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the Summary Compensation Table and the other compensation related tables and disclosure.”

As this vote is advisory, it will not be binding upon the Board of Directors or the Compensation Committee and neither the Board of Directors nor the Compensation Committee will be required to take any action as a result of the outcome of this vote. However, the Compensation Committee will carefully consider the outcome of this vote when considering future executive compensation policies.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE ADVISORY RESOLUTION TO APPROVE THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS
