Michael Steinhardt has served as our non-executive Chairman of the Board since November 2004. From 1967 through 1995, Mr. Steinhardt served as Senior Managing Partner of Steinhardt Partners, L.P., a private investment company, and related investment entities. In 1995, Mr. Steinhardt closed Steinhardt Partners and eliminated his involvement in managing client assets. He founded and now serves as President of Steinhardt Management Co., Inc., which currently manages a single private investment fund investing in other funds managed by independent investment managers. Mr. Steinhardt currently devotes most of his time and financial resources to Jewish philanthropic causes, directed through The Steinhardt Foundation for Jewish Life for which he serves as Chairman. Mr. Steinhardt is the co-founder of Birthright Israel and he serves on its Board of Trustees and is a major supporter. He also serves as Co-Chair of the Areivim Philanthropic Group.

Mr. Steinhardt received his B.S. in Economics from The Wharton School of Business of the University of Pennsylvania. We believe Mr. Steinhardt’s qualifications to serve on the Board of Directors include his extensive years of experience as a founder of a private investment management company. The board also benefits from his perspective and knowledge of financial markets as well as his strategic vision. On January 6, 2012, the Court of Chancery of the State of Delaware issued an opinion imposing sanctions on the chairman of our Board of Directors, Mr. Steinhardt, which required him, among other things, to self-report certain trading activity not involving the Company’s securities to the SEC. Mr. Steinhardt’s actions did not involve the Company. For more details, see the section entitled “Involvement in Certain Legal Proceedings.”

Steven L. Begleiter has served as a member of our Board of Directors since February 2011. Mr. Begleiter has served as Senior Principal at Flexpoint Ford, LLC, a private equity group focused on investments in financial services and healthcare, since October 2008. Prior to joining Flexpoint Ford, Mr. Begleiter spent 24 years at Bear Stearns & Co., serving first as an investment banker in the Financial Institutions Group and then as Senior Managing Director and member of its Management and Compensation Committee from 2002 to September 2008. Mr. Begleiter also served as head of Bear Stearns’ Corporate Strategy Group. Mr. Begleiter received his B.A. in Economics with honors from Haverford College. We believe Mr. Begleiter’s qualifications to serve on the Board of Directors include his many years of experience in leadership positions in the financial services industry as well as his private equity experience. The board also benefits from his extensive industry knowledge and perspectives on capital formation.

Anthony Bossone has served as a member of our Board of Directors since January 2009. Since 2003 Mr. Bossone has been the Chief Financial Officer of Atlantic-Pacific Capital, Inc., a broker-dealer and global placement agent dedicated to raising capital for alternative investment funds. From 2001 to 2003, Mr. Bossone was the Assistant Controller at SAC Capital Advisors, LLC, a hedge fund advisory firm, and from 1999 until 2001, Mr. Bossone served as an equity trader at Schonfeld Securities, LLC, a securities trading firm.

Mr. Bossone received his B.S. in Business and Economics with highest honors from Lehigh University and is a Certified Public Accountant. We believe Mr. Bossone’s qualifications to serve on the Board of Directors include his financial and accounting expertise. The board also benefits from his experience as an equity trader.

R. Jarrett Lilien has served as a member of our Board of Directors since November 2008. Since January 2009, Mr. Lilien has served as Managing Partner of Bendigo Partners, a private equity and consulting firm focused on technology-enabled financial service companies, which he co-founded. Between 1999 and May 2008, Mr. Lilien was employed by E*Trade Financial Corporation, a brokerage and financial services firm, holding various positions including President and Chief Operating Officer, from 2003 to May 2008, and Acting Chief Executive Officer, from November 2007 until March 2008. Prior to his service at E*Trade, Mr. Lilien was Chief Executive Officer of TIR Securities, a global institutional brokerage firm that he co-founded in 1989 and which

4

was later sold to E*Trade. Prior to TIR Securities, Mr. Lilien held various positions at Paine Webber and Autranet, Inc., a division of Donaldson, Lufkin & Jenrette, Inc., both brokerage and financial service firms. Mr. Lilien currently serves as President of the Jazz Foundation of America and is on the Board of Directors of the Baryshnikov Arts Center and on the Advisory Board of WFUV FM Radio. Mr. Lilien received his B.A. in Economics from the University of Vermont. We believe Mr. Lilien’s qualifications to serve on the Board of Directors include his experience in founding and building financial services companies. The board also benefits from his extensive leadership experience and his ability to provide strategic guidance.

James D. Robinson, IV has served as a member of our Board of Directors since November 2004. Mr. Robinson is a Managing Partner of RRE Ventures, LLC, a venture capital firm primarily focused on technology companies, which he co-founded in 1994. From 1992 to 1994 Mr. Robinson was employed by Hambrecht & Quist Venture Capital, a venture capital firm, where he served as a General Partner for several investment funds for the firm. From 1986 to 1992, he was employed by JP Morgan & Company, where he worked on technology-related assignments, first within the Global Exposure Management group building risk management systems, and later as an investment banker in the Corporate Finance group focused on technology and communications companies.

Mr. Robinson received a B.A. with a double degree in Computer Science and Business Administration from Antioch College and an M.B.A. from Harvard University. We believe Mr. Robinson’s qualifications to serve on the Board of Directors include his experience in building and financing companies from earliest stages of growth. In addition, Mr. Robinson’s venture capital experience as well as his insight into capital formation enables him to provide the board with valuable strategic advice.

Frank Salerno has served as a member of our Board of Directors since July 2005. From July 1999 until his retirement in February 2004, Mr. Salerno was Managing Director and Chief Operating Officer of Merrill Lynch Investment Advisors—Americas Institutional Division, an investment advisory company. Before joining Merrill Lynch, Mr. Salerno spent 18 years with Bankers Trust Company in various positions. In 1990, he assumed responsibility for Bankers Trust’s domestic index management business and in 1995 he became Chief Investment Officer for its Structured Investment Management Group. Mr. Salerno received a B.S. in Economics from Syracuse University and an M.B.A. in Finance from New York University. Mr. Salerno served as a director and member of the audit committee and conflicts committee of K-Sea Transportation Partners, L.P., formerly a NYSE-listed company, from 2004 until its acquisition in 2011. We believe Mr. Salerno’s qualifications to serve on the Board of Directors include his extensive years in senior management positions at large asset management firms as well as his service on the board of directors of another public company. The board also benefits from his strategic insights on the asset management industry.

Board Composition

Our Board of Directors currently consists of eight members. 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.

Our 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 2013 for Class II directors, 2014 for Class III directors and 2015 for Class I directors.

5

Our amended and restated certificate of incorporation and amended and restated 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. Any additional 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.

In a private placement of our common stock in November 2009, we entered into a Securities Purchase Agreement that provided, among other things that as long as Michael Steinhardt individually, and RRE Ventures III-A, L.P., RRE Ventures Fund III, L.P., and RRE Ventures III, L.P. (collectively the “RRE Entities”), collectively, beneficially own at least 10,000,000 shares of common stock, they each shall have the independent right to require the Company to either (i) appoint a designee, reasonably acceptable to our Board of Directors, as a member of our Board of Directors, or (ii) provide a designee with notice of all board meetings and copies of all materials delivered to members of our Board of Directors and permit such designee to attend and observe each meeting of our Board of Directors. We further agreed that Mr. Steinhardt and James D. Robinson, IV, as the designees of Mr. Steinhardt and the RRE Entities, respectively, were acceptable designees of Mr. Steinhardt and the RRE Entities, respectively. Mr. Steinhardt continues to beneficially owns at least 10,000,000 shares of our common stock and therefore continues to be contractually entitled to designate a director or an observer. The beneficial ownership of the RRE Entities was reduced to 1,263,789 shares in connection with the public offering in November 2012, and thus the RRE Entities are no longer contractually entitled to designate a director or observer.

Board Leadership Structure and Board’s Role in Risk Oversight

The positions of Chairman of the Board and Chief Executive Officer are separated. We believe that separating these positions allows our Chief Executive Officer to focus on our day-to-day business, while allowing the chairman of the board to lead 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 this Report. 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.

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, Robinson, 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:

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.

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:

7

Compensation Committee. Messrs. Steinhardt, Lilien and Salerno currently serve on the Compensation Committee, which is chaired by Mr. Salerno. The Compensation Committee’s responsibilities include:

Nominating Committee. Messrs. Steinhardt, Lilien and Robinson currently serve on the Nominating Committee, which is chaired by Mr. Steinhardt. The Nominating Committee’s responsibilities include:

Our Board of Directors may from time to time establish other committees.

Compensation Committee Interlocks and Insider Participation

During 2012, none of our executive officers served as: (i) a member of the Compensation Committee (or other committee of the board of directors performing equivalent functions or, in the absence of any such committee, the entire board of directors) of another entity, one of whose executive officers served on our Compensation Committee; (ii) a director of another entity, one of whose executive officers served on our Compensation Committee or (iii) a member of the Compensation Committee (or other committee of the board of directors performing equivalent functions or, in the absence of any such committee, the entire board of directors) of another entity, one of whose executive officers served on our Board of Directors.

Involvement in Certain Legal Proceedings

The Chairman of our Board of Directors and beneficial owner of approximately 15.4% of our common stock, Michael Steinhardt, was the plaintiff in a civil class action filed in the Court of Chancery of the State of Delaware, in a case entitled Michael Steinhardt, Herbert Chen, Derek Sheeler, Steinhardt Overseas Management, L.P., and Ilex Partners, L.L.C., v. Robert Howard-Anderson, Steven Krausz, Robert Abbott, Robert Bylin, Thomas Pardun, Brian Strom, Albert Moyer, and Occam Networks, Inc., C.A. No. 5878-VCL. Occam Networks, Inc., was a publicly traded Delaware corporation that announced on September 16, 2010, that it had entered into merger agreement with Calix, Inc., another publicly traded company in the telecommunications equipment industry. Plaintiffs, Occam shareholders, filed the class action challenging the merger. As part of these proceedings, the court entered a confidentiality order to protect the non-public information that would be exchanged in discovery. This order contained both a general requirement that non-public information produced in the action be used solely for purposes of the litigation and a specific restriction against purchasing, selling, or otherwise trading in the securities of Occam or Calix on the basis of such information. Beginning on December 28, 2010, Mr. Steinhardt began short-selling Calix stock as a way to exit his Occam position. The defendants filed a motion for sanctions on the basis that Delaware law prohibits plaintiff-fiduciaries from trading stock while they are in possession of non-public information they obtained in discovery. After conducting an evidentiary hearing, the court granted the defendants’ motion for sanctions with respect to Mr. Steinhardt and his

8

affiliated funds on January 6, 2012. The court dismissed Mr. Steinhardt and his affiliated funds from the case with prejudice, barred them from receiving any future recovery in the lawsuit, required them to self-report their trading activities to the SEC and disclose it in any future application to serve as lead plaintiff, and ordered them to disgorge profits of over $530,000.

Mr. Steinhardt’s actions did not involve the Company or trading in the Company’s securities and, based on the facts currently known, which we are continuing to monitor, we do not believe Mr. Steinhardt’s actions have had or will have a material impact on our business. However, there can be no assurance that this will be the case or that this will not have an adverse effect on our reputation or the price of our common stock.

Section 16(a) Beneficial Ownership Reporting Compliance

All of our Section 16 reporting persons timely complied with their reporting obligations under Section 16(a) of the Securities Exchange Act of 1934, as amended.

Corporate Governance

We have adopted a code of conduct that applies to all of our employees, officers and directors, including those officers responsible for financial reporting. Our code of conduct is available on our website at http://ir.wisdomtree.com/. We intend to disclose any amendments to this code, or any waivers of its requirements, on our website.

Compensation Discussion and Analysis

Overview

This Compensation Discussion and Analysis provides comprehensive information regarding our compensation programs and policies for our named executive officers, who consist of:

We provide what we believe is 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:

Our Compensation Philosophy and Objectives

Our compensation philosophy and objectives are primarily shaped by strategies 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:

A key component of our long-term success is our ability to employ the industry’s most talented, professional and dedicated people at all levels within the Company. Therefore, our employees are critical to our long-term success.

The primary objectives of our compensation program are as follows:

10

The following principles guide our compensation programs:

To achieve these objectives, we seek to provide competitive compensation packages recognizing and rewarding individual contributions to ensure that executive compensation is aligned with corporate strategies and business objectives.

Factors Considered in Evaluating Total Compensation for our Executive Officers

The Compensation Committee considers the following un-weighted factors (listed in no particular order) to ensure that compensation is fair, reasonable, competitive and consistent with our compensation philosophies and objectives referred to above:

11

The Compensation Committee considers the factors above, together with their collective experiences and business judgment, to evaluate our compensation practices. The Compensation Committee believes this general approach helps us to compete in hiring and to retain the best possible talent while at the same time maintaining a reasonable and responsible cost structure.

Role of the Compensation Committee

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 as a team 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 does engage a compensation consultant with respect to executive compensation as needed.

The Compensation Committee specifically evaluates the performance of our CEO and indirectly, the 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 of the CEO, 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 and other senior employees under the Committee’s purview, 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.

Role of Management

Our executive officers play a critical and important role in setting or recommending compensation levels throughout our organization. Our CEO makes incentive compensation recommendations for the executive

12

officers to the Compensation Committee. In considering the CEO’s recommendations, the Compensation Committee considers the factors discussed above to ensure that compensation is fair, reasonable, competitive and consistent with our compensation philosophies and objectives.

Our CFO and CLO work with our CEO and Chairman of 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.

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:

The Compensation Committee uses this information as reasonable and useful starting points for compensation decisions to understand evolving pay trends at asset managers.

Use of Compensation Consultants

The Committee retains Frederick W. Cook & Co., a compensation consultant, to provide objective advice on the pay practices and the competitive landscape for compensation. The compensation consultant also reviews McLagan survey information and selection process and pay information for the publicly traded industry peers.

Consideration of Results of Say-on-Pay Vote

At our 2012 annual meeting of stockholders, we provided our stockholders with the opportunity to cast an advisory vote on our fiscal year 2011 compensation paid to our named executive officers, or say-on-pay. At that meeting, 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.

Employment Agreements

We have entered into employment agreements with our COO, CFO, CLO and VC which establishes minimum base salary and cash incentive compensation, severance, change in control, certain post-employment restrictive covenants and other benefits. The Compensation Committee believes it is appropriate to maintain these agreements and benefits in order to provide certainty to our executive officers and VC to support a stable executive management team focusing on our long-term success. We do not maintain employment agreements with our CEO or CIS as the Compensation Committee believes that their significant equity ownership of the Company as co-creators of our fundamentally weighted methodology, aligns their interest with our long-term success.

13

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 COO, CFO and CLO have minimum base compensation of $300,000 under their employment agreements.

Annual Incentive Compensation

We have established an annual bonus program to reward our executive officers, as well as all our employees, for their individual performance as well as Company performance. Incentive compensation is intended to motivate executives to achieve company-wide operating and strategic objectives. This award is granted in cash and restricted stock. Our COO, CFO and CLO have minimum annual cash incentive compensation of $200,000 under their employment agreements.

Long-Term Equity Compensation

Because short-term performance does not by itself accurately reflect our overall performance nor the return realized by our stockholders, our employees are eligible to receive equity awards. We believe that providing equity ownership:

Our equity award program is the primary vehicle for offering long-term incentives to our executives. In determining the size and mix of equity grants to our executives, our Compensation Committee used their collective experiences and business judgment and considered the executives’ level of responsibility, the executives’ ability to significantly influence our growth and profitability, the executives previous experience, and the amount of equity awarded to our other executives.

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

14

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 401(k) plan, group health plans, paid vacation and sick leave, basic life insurance and short-term and long-term disability benefits.

Severance

Pursuant to employment agreements we have entered into with our COO, CFO, CLO and VC each of them is entitled 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 include partial acceleration of unvested restricted stock and option awards and guaranteed minimum severance payments and benefits.

Change-in-Control Benefits

Upon a change in control that occurs during the employment of our executive officers or, in certain circumstances, within six or twelve 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 and any 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.”

Our goal in providing severance and change in control benefits is to offer certainty regarding the potential protection such that our executive officers will: (i) focus their attention and decision-making on the requirements of the business, and (ii) cooperate in negotiating any change in control in which they believe they may lose their jobs. 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.

Tax and Accounting Considerations

Currently, accounting and tax treatment of particular forms of compensation are considered but do not materially affect our compensation decisions. However, in the future as we continue to gain experience with our compensation policies and grow our business, we will evaluate the effect of such accounting and tax treatment on an ongoing basis and will make appropriate modifications to compensation policies where appropriate. For example, 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 four other most highly compensated executive officers. Qualifying performance-based compensation is not subject to the deduction limitation if specified requirements are met. We believe we will structure the performance-based portion of our executive compensation, in the future, where feasible, to comply with exemptions in Section 162(m) so that the compensation 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.

2012 Compensation

Change in Equity Granting Practice and Total Compensation Competitive Review

In 2012, we began a process to examine our practice of granting equity awards to our employees. In the past, when employees were hired, we would grant them a significant long-term equity award that would vest over four years. When that initial award was about to fully vest, we often replenished the award with a more modest long-term award. We also granted special long-term equity awards from time to time to certain employees to recognize their exemplary performance or promotions as part of their year-end compensation. In 2009, because most of our employees had options that were significantly out of the money, our Board and Compensation

15

Committee approved a proposal to provide eligible employees an opportunity to exercise their underwater stock options in the future at an alternative lower strike price. To obtain the full benefit of the alternative strike price, employees were required to remain with us for an additional four years. In effect, this re-pricing was like a new equity grant and eliminated the need for us to grant replenishment long-term equity awards after the re-pricing other than special awards to recognize employees’ exceptional performance. Since most of these equity awards would fully vest by January 2013, the Compensation Committee directed our CFO and CLO to review our grant practices and shift from the practice described above, which is more typical for a start-up company, to an annual granting practice, which is a more typical for maturing companies and companies in the financial services industry. As part of this review, compensation consultants from Frederick W. Cook & Co. provided guidance to the Compensation Committee and our CFO and CLO to help redesign our equity grant practice.

In conjunction with the change in equity granting practice, we also undertook a market study to ensure our pay levels were competitive within the asset management industry relative to our size and location in New York City. This study was done for all employees, including our executive officers. Working with our compensation consultant, we analyzed competitive pay information for each individual position provided by McLagan where an appropriate match of position and responsibilities could be made. This market data was one factor used in the evaluation along with our judgment based on each individual’s performance and our business needs. In addition, we reviewed average total compensation levels which included the value of any long-term equity awards which were not considered as part of total compensation in the past. For the executive officers, peer information from other publicly traded asset managers were also analyzed, which included Artio Global Investors, Calamos Asset Management, CIFC Corp, Cohen & Steers, Diamond Hill Investment, Epoch Holdings, Financial Engines, GAMCO Investors, Manning & Napier, Virtus Investment Partners, and Westwood Holdings Group. These firms were selected because of their similar size, market capitalization, product offering or financial metrics as WisdomTree. The analysis was presented to the Compensation Committee and considered in determining total compensation for our executive officers and the total compensation pool for WisdomTree.

Change in Executive Management

In April 2012, our Board of Directors appointed our CEO as President and CEO. Our then President and Chief Operating Officer, Bruce Lavine, relinquished his President and Chief Operating Officer responsibilities to serve as Vice Chairman and relocated to California for family reasons. Mr. Lavine continues to serve in a leadership role and is a member of our Board of Directors. In October 2012, Gregory Barton joined us as Chief Operating Officer. In connection with his new role as Vice Chairman, Mr. Lavine’s compensation was changed. He received a prorated incentive compensation award based on his 2011 compensation; his base salary was reduced to $25,000; and he will no longer be eligible for any incentive compensation. Mr. Lavine agreed to extend the vesting conditions of his long-term equity awards whereby they would ratably vest through 2015 instead of 2014, essentially enhancing their retention characteristics.

2012 Performance Background

We have been and continue to operate in an extremely challenging and highly competitive business environment. Equity markets have generally improved; however, the markets continue to experience significant volatility. The level of flows into the equity markets have been tepid since the financial crisis; although ETF flows hit record levels in 2012. Despite a challenging economic environment, our AUM and net inflows have been growing and reaching record levels which has also translated into record revenues and earnings.

Highlights of 2012 and goals established at the beginning of the year that the Compensation Committee considered in evaluating the performance of our executive officers included:

16

2012 Compensation Results

Given the change in equity granting practice and competitive analysis on compensation, our CEO and Compensation Committee focused on determining the appropriate level of total compensation for each of our executive officers. Our CEO and Compensation Committee use their business judgment, and considered:

In determining the total compensation for our CEO, the Compensation Committee placed more emphasis on publicly traded peer information as this was an easily comparable position. Our CEO also placed more emphasis on publicly traded peer data in determining our CFO’s total compensation as it was easily comparable. Our CEO placed more emphasis on survey data for our CIS and CLO’s total compensation and subjectively determined an incentive compensation amount for our COO given his short tenure with the firm.

17

The table below reflects the total compensation granted to our 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 required by the SEC:

Long-term equity awards were granted in January 2013 and represent restricted stock which will vest 50% in January 2014, 25% in January 2015 and 25% in January 2016. The values for the long-term equity awards represent the accounting grant date fair values in accordance with U.S generally accepted accounting principles.

Acceleration of Bonus Payments and Stock Vesting

Due to the “fiscal cliff” issues and the probability of higher taxes in 2013 for highly compensated employees, including our executive officers, our Compensation Committee approved the payment of a significant portion of 2012 performance year cash bonuses in December 2012 instead of February 2013. In addition, they approved the accelerated vesting of restricted stock due to vest in January 2013 to December 2012. The Compensation Committee determined it was appropriate to provide this benefit to our executive officers to minimize their tax payments and considered this benefit when determining total compensation for our executive officers for 2013.

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.

Conclusion

After careful review and analysis, we believe that each element of compensation and the total compensation provided to each of our executive officers is reasonable and appropriate. Through the compensation arrangements described above, a portion of each executive’s compensation is contingent on our company-wide and their individual performance. Therefore, the realization of benefits by the executive is closely linked to our achievements and increases in stockholder value. We remain committed to our compensation philosophies and the Compensation Committee gives careful consideration to our executive compensation program, including each element of compensation for each executive. The Compensation Committee believes that our compensation program gives each executive 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

18

for outstanding stockholder returns, without taking unnecessary or excessive risks. 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.

Mr. Ziemba may also elect to have us pay for COBRA insurance coverage for a one-year period following his termination.

Bruce Lavine

On April 24, 2012, in connection with an expected change in status of then President and Chief Operating Officer, Bruce Lavine, we entered into a new employment agreement which became effective on August 1, 2012. The new agreement provides for Mr. Lavine’s continued employment in a full time capacity for a three year term expiring August 1, 2015. The following is a summary of the changes to Mr. Lavine’s compensation arrangements pursuant to the Agreement. Mr. Lavine will continue to be employed in a full time capacity until August 1, 2015. Mr. Lavine’s annual base salary was reduced from the previous annual rate of $300,000 to $25,000. Mr. Lavine will not be entitled to receive bonuses. For Mr. Lavine’s service as President and Chief Operating Officer during the 2012 fiscal year, Mr. Lavine received a prorated bonus of $271,615. 150,000 stock options awarded to Mr. Lavine on January 26, 2009 that were scheduled to vest on January 26, 2014 will now vest on July 31, 2015. 150,000 shares of restricted stock awarded on January 26, 2009 that were scheduled to vest on February 16, 2013 will now vest on July 31, 2013. 150,000 shares of restricted stock awarded on January 26, 2009 that were scheduled to vest on February 16, 2014 will now vest on July 31, 2014.

Prior to April 24, 2012, under the former employment agreement with Mr. Lavine which has now been replaced, Mr. Lavine’s employment had been for an indefinite term and on an “at will” basis. This former agreement provided for a base salary of $300,000 and entitled Mr. Lavine to a guaranteed minimum annual bonus of $200,000. Mr. Lavine, however, was subject to a restrictive covenant that prohibits him from working for a competitor for a one-year period after he gives the Company notice of his voluntary termination of employment or if his employment was terminated for cause. The agreement also entitled Mr. Lavine 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 contained employee confidentiality and assignment of inventions provisions. Mr. Lavine was 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 would have paid Mr. Lavine, in addition to all accrued but unpaid base salary and guaranteed minimum annual 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 pro rated guaranteed minimum bonus for the year in which the termination occurs, subject to certain adjustments in the event Mr. Lavine had provided notice of his intent to resign. Mr. Lavine could have also elected to have us pay for COBRA insurance coverage for a one-year period following his termination.

Potential Payments upon Termination or Change of Control

Certain of 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

23

from employment or change in control, as the case may be, occurred on December 31, 2012, 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.

24

Severance Arrangements

Pursuant to the terms of their employment agreements, each of Messrs. Barton, Muni, Ziemba and Lavine is 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. Barton, Muni and Ziemba, in addition to all accrued but unpaid base salary, the guaranteed minimum annual cash bonus and any discretionary 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. Mr. Lavine will receive, in addition to all accrued but unpaid base salary, an amount equal to the sum of one-year’s base salary Each of Messrs. Barton, Muni, Ziemba and Lavine may also elect to have us pay for COBRA insurance coverage for a one-year period following his termination, Messrs. Muni and Ziemba would have each received incremental values of $721,675, Mr. Barton $568,340 and Mr. Lavine $37,952 as a result of the provisions of these employment agreements. The amount for Mr. Barton would have been less than the amount that would have been received by Messrs. Muni and Ziemba solely because he would only have received a pro-rated portion of his guaranteed minimum annual cash bonus for 2012 since he commenced his employment on October 8, 2012. Messrs. Steinberg and Siracusano are not party to employment agreements.

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 the change of control had occurred on December 31, 2012, Messrs. Steinberg, Muni, Siracusano, and Ziemba would have received incremental values of $2,371,250, $539,250, $271,000, and $1,010,000, 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 was on December 31, 2012, Messrs. Muni and Ziemba would have received incremental values of $378,750 and $1,010,000, respectively.

Acceleration of Restricted Stock

Certain of the restricted stock awards we have granted to each of Messrs. Barton, Muni 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 the change of control had occurred on December 31, 2012, Messrs. Barton, Muni and Ziemba would have received incremental values of $1,224,000, $994,500 and $994,500, respectively.

Certain of the restricted stock awards we have granted to each of Messrs. Barton, Muni , Ziemba and Lavine 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. As a result, assuming such termination occurred on December 31, 2012, Messrs. Barton, Muni, Ziemba and Lavine would have received incremental values of $306,000, $0, $0 and $918,000, respectively.

25

Compensation of Directors

The Board of Directors has determined that each of our non-employee directors who does not hold his membership on the Board of Directors pursuant to a contractual right granted to investors in one or more of our private placements (see “Directors, Executive Officers and Corporate Governance –Board Composition”) is entitled to receive compensation for service as a director. At December 31, 2012 and 2011, four directors were qualified to receive compensation under this program: Messrs. Begleiter, Bossone, Lilien and Salerno. However, in connection with his appointment to our Board of Directors in February 2011, Mr. Begleiter waived his right to receive compensation for three years. Mr. Bossone similarly waived his right to receive compensation for three years in connection with his nomination for re-election to the Board at our Annual Meeting of Stockholders in July 2012. Under this compensation program these qualifying directors receive a grant of equity valued at $300,000 on the date of grant based on the volume weighted average price of our common stock over the 30 trading days immediately prior to the grant date. This award vests over three years on the first three anniversaries of the date of grant.

In addition, each of these directors receives the following annual retainers:

All of our directors are reimbursed for out-of-pocket expenses for attending meetings. Our directors also participate in the insurance and indemnification arrangements described below.

The following table describes director compensation for non-management directors for the year ended December 31, 2012. Messrs Salerno and Lilien were the only directors to receive compensation in the years ended December 31, 2012. Directors who are also officers of WisdomTree are not entitled to any compensation for their services as a director.

Director Compensation Table for the 2012 Fiscal Year

Limitation of Liability and Indemnification Arrangements

As permitted by the Delaware General Corporation Law, or the DGCL, our amended and restated certificate of incorporation and amended and restated by-laws limit or eliminate the personal liability of our directors. Consequently, a director will not be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director, except for liability for:

26

These limitations of liability do not alter director liability under the federal securities laws and do not affect the availability of equitable remedies such as an injunction or rescission.

In addition, our amended and restated by-laws provide that:

We have also entered into indemnification agreements with each of our executive officers and directors. These agreements provide that we will indemnify each of our directors to the fullest extent permitted by the DGCL and advance expenses to each indemnitee in connection with any proceeding in which indemnification is available.

We also maintain general liability insurance to provide insurance coverage to our directors and officers for losses arising out of claims based on acts or omissions in their capacities as directors or officers, including liabilities under the Securities Act of 1933, as amended, or the Securities Act. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, or persons controlling the registrant pursuant to the foregoing provisions, we have been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

These provisions may discourage stockholders from bringing a lawsuit against our directors in the future for any breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. Furthermore, a stockholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors, officers and certain employees pursuant to these indemnification provisions. We believe that these provisions, the indemnification agreements and the insurance are necessary to attract and retain talented and experienced directors and officers.

At present, there is no pending litigation or proceeding involving any of our directors, officers or employees in which indemnification will be required or permitted. We are not aware of any threatened litigation or proceeding that might result in a claim for such indemnification.

The following table sets forth information regarding the beneficial ownership of shares of our common stock as of February 15, 2013 (except as otherwise indicated in the footnotes) by:

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., 380 Madison Avenue, 21^st Floor, New York, N.Y. 10017. We have based our calculation of the percentage of beneficial ownership on 125,541,755 shares of our common stock outstanding as of February 15, 2013, 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.
