VOTING INSTRUCTION AND INFORMATION

Why did I receive a Notice regarding the Availability of Proxy Materials?

In accordance with Securities and Exchange Commission (“SEC”) rules, instead of mailing a printed copy of our proxy materials, we may send a Notice of Internet Availability of Proxy Materials (the “Notice”) to stockholders. All stockholders will have the ability to access the proxy materials on a website referred to in the Notice or to request a printed set of these materials at no charge. You will not receive a printed copy of the proxy materials unless you specifically request one. Instead, the Notice instructs you as to how you may access and review all of the important information contained in the proxy materials via the Internet and submit your vote via the Internet or telephonically.

In addition, you may request to receive future proxy materials on an ongoing basis (i) electronically by e-mail or (ii) in printed form by mail. Choosing to receive future proxy materials by e-mail will save the Company the cost of printing and mailing documents to stockholders and will reduce the impact of annual meetings on the environment. Your election to receive proxy materials by e-mail or by mail will remain in effect until you terminate it.

Who can vote at the Annual Meeting?

You are entitled to vote your shares of Class A common stock, par value $0.01 per share (the “common stock”), of the Company if you were a stockholder at the close of business on February 27, 2020, the record date for the Annual Meeting. At the close of business on the record date, 76,751,240 shares of common stock were outstanding. In addition, 100 shares of Class B common stock, par value $0.01 per share (the “Class B common stock”), of the Company were outstanding. All of the outstanding shares of Class B common stock are held of record by IBG Holdings LLC (“Holdings”), an entity controlled by Mr. Thomas Peterffy, our founder and Chairman, through his indirect ownership of the voting membership interests in Holdings.

The holders of the common stock and the Class B common stock will vote together as a single class on each of the proposals described in this proxy statement. The holder of each share of the common stock is entitled to one vote per share. Pursuant to our Amended and Restated Certificate of Incorporation, the holder of each share of the Class B common stock is entitled to 3,386,706 votes (that number equal to the number of membership interests in IBG LLC, the holding company for our businesses, such holder held on the record date divided by 100). Accordingly, Holdings, as the sole holder of the Class B common stock, is expected to be entitled to 338,670,642 votes in the aggregate, or approximately 81.5% of all votes eligible to be cast at the Annual Meeting.

As of March 9, 2020, our directors and executive officers beneficially owned an aggregate of approximately 2,482,676 shares of common stock and restricted stock unit awards (“stock awards”) that vest within 60 days, constituting approximately 3.23% of the common stock outstanding as of such date, of which 2,289,296 shares can be voted at the annual meeting and constituting approximately 0.55% of all votes eligible to be cast at the Annual Meeting. This does not include the 2,411,525 shares beneficially owned by Echinus Advisors, LLC (“Echinus”) of which Philip Uhde is the manager and majority controlling person. See “Beneficial Ownership of Directors, Executive Officers and Owners of More than Five Percent” for more information regarding Echinus’ shares. It is expected that such directors and executive officers will vote or direct the vote of all shares of common stock held or owned by such persons, or over which such persons have voting control, in favor of the proposals described in this proxy statement. It also is expected that Holdings will vote its shares of Class B common stock, expected to constitute approximately 81.5 % of all votes eligible to be cast at the Annual Meeting, in favor of the proposals. Accordingly, the voting power of Holdings alone is sufficient to assure the approval of the proposals. See “Beneficial Ownership of Directors, Executive Officers and Owners of More Than Five Percent.”

Who is and is not a stockholder of record?

If you are a stockholder of record, Broadridge is sending these proxy materials to you directly. If you hold shares in street name, these materials are being sent to you by the bank, broker or similar institution through which you hold your shares.

What do I need to do to attend the Annual Meeting?

All stockholders must bring an acceptable form of identification, such as a driver’s license, in order to attend the Annual Meeting in person.

In addition, if you hold shares of common stock in “street name” and would like to attend the Annual Meeting, you will need to bring an account statement or other acceptable evidence of ownership of shares as of the close of business on February 27, 2020, the record date for the Annual Meeting.

How do I request paper copies of the proxy materials?

If you received a Notice by mail, you will not receive paper copies of the proxy materials in the mail unless you request them. Instead, the Notice instructs you on how to access and read the Proxy Statement and Annual Report and how you may submit your proxy over the Internet. If you received a Notice by mail and would like to receive a printed copy of the materials, please follow the instructions on the Notice for requesting the materials, and we will promptly mail the materials to you.

How do I vote?

You may vote using any of the following methods:

If you are located within the United States or Canada, you can vote your shares by telephone by calling the toll-free telephone number printed on the Notice, on your proxy card, or in the instructions that accompany your proxy materials, as applicable, and following the recorded instructions. You will need the control number printed on the Notice, on your proxy card, or in the instructions that accompany your proxy materials, as applicable. Telephone voting is available 24 hours a day and will be accessible until 11:59 p.m. EDT on April 22, 2020. The telephone voting system has easy to follow instructions and allows you to confirm that the system has properly recorded your vote. If you vote by telephone, you do NOT need to return a proxy card or voting instruction form. If you are an owner in street name, please follow the instructions that accompany your proxy materials.

You can also choose to vote your shares by the Internet. You will need the control number printed on your Notice, on your proxy card, or in the instructions that accompany your proxy materials, as applicable. The web site for Internet voting is listed on your Notice, proxy card, or in the instructions that accompany your proxy materials. Internet voting is available 24 hours a day and will be accessible until 11:59 p.m. EDT on April 22, 2020. As with telephone voting, you will be able to confirm that the system has properly recorded your vote. If you vote via the Internet, you do NOT need to return a proxy card or voting instruction form.

If you are a holder of record and received printed copies of the materials by mail, you may choose to vote by mail. Simply mark your proxy card, date and sign it, and return it in the postage-paid envelope that we included with your materials. If you hold your shares through a bank or brokerage account, please complete and mail the voting instruction form in the envelope provided.

You may also vote by ballot at the Annual Meeting if you decide to attend in person or through our link at www.shareholdermeeting.com/IBKR2020. If your shares are held in the name of a bank, broker or other holder of record, you must obtain a proxy, executed in your favor, from the holder of record to be able to vote at the meeting. All shares that have been properly voted and not revoked will be voted at the Annual Meeting. If you sign and return a proxy card but do not give voting instructions, the shares represented by that proxy card will be voted as recommended by the Board of Directors. Returning the proxy card or voting by telephone or via the internet does not deprive you of your right to attend the meeting, in person or virtually.

The Internet and telephone voting procedures are designed to authenticate stockholders’ identities, to allow stockholders to give their voting instructions and to confirm that stockholders’ instructions have been recorded properly. We have been advised that the Internet and telephone voting procedures that have been made available to you are consistent with the requirements of applicable law. Stockholders voting by Internet or telephone should understand that, while we and Broadridge do not charge any fees for voting by Internet or telephone, there may nevertheless be costs, such as usage charges from Internet access providers and telephone companies that must be borne by the stockholder.

How can I revoke my proxy or substitute a new proxy or change my vote?

You can revoke your proxy or substitute a new proxy or change your vote before your proxy is voted at the Annual Meeting.

How can I obtain an additional proxy card?

If you lose, misplace or otherwise need to obtain a proxy card, and:

If I submit a proxy by Internet, telephone or mail, how will my shares be voted?

If you properly submit your proxy by one of these methods, and you do not subsequently revoke your proxy, your shares of common stock will be voted in accordance with your instructions.

If you sign, date and return your proxy card but do not give voting instructions, your shares of common stock will be voted as follows: FOR the election of our director nominees, FOR the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2020, and otherwise in accordance with the judgment of the persons voting the proxy on any other matter properly brought before the Annual Meeting.

If I hold my shares in “street name” and do not provide voting instructions, can my broker still vote my shares?

Brokerage firms have authority to vote clients’ unvoted shares on some “routine” matters. When a brokerage firm votes its clients’ unvoted shares on routine matters, these shares are counted to determine if a quorum exists to conduct business at the meeting. A brokerage firm cannot vote clients’ unvoted shares on non-routine matters, which results in a broker non-vote. A broker non-vote will be treated as not being entitled to vote on the proposal. For proposals that require a majority of votes voting on the proposal to be approved (such as the stockholder proposals), a broker non-vote will not be counted for purposes of determining whether the proposal has been approved.

The Company’s proposal to elect directors is considered a routine matter, but the stockholder proposals are not.

What vote is required for a director to be elected or for the other proposals to be ratified?

Election of Directors You may vote FOR or AGAINST any or all director nominees or you may ABSTAIN as to one or more director nominees. A majority of the votes cast FOR or AGAINST the election of a director nominee must be voted FOR the director nominee in order for the director nominee to be elected. A vote to ABSTAIN is not treated as a vote FOR or AGAINST and thus will have no effect on the outcome of the vote. A director nominee who fails to receive a majority of FOR votes will be required to tender his or her resignation to our Board for consideration.

Ratification of the Appointment of Independent Auditors You may vote FOR or AGAINST the ratification of the appointment of our independent registered public accounting firm or you may ABSTAIN. A majority of the votes cast FOR or AGAINST ratification must be voted FOR ratification for it to pass. A vote to ABSTAIN is not treated as a vote FOR or AGAINST and thus will have no effect on the outcome of the vote.

Broker Non-Vote A failure by your broker to vote your shares of common stock when you have not given voting instructions will have no effect on the outcome of the vote on discretionary matters, i.e., the election of directors or the ratification of the independent public registered accounting firm. A “broker non-vote” occurs when you do not provide the broker with voting instructions on non-discretionary matters and the broker cannot vote your shares on these matters. Because the affirmative vote of a majority of the outstanding shares is necessary to approve each stockholder proposal, a broker non-vote will have the effect of a vote AGAINST that proposal.

How many votes are required to transact business at the Annual Meeting?

A quorum is required to transact business at the Annual Meeting. The presence of Holdings, as the sole holder of the Class B common stock, will constitute a quorum for the transaction of business at the Annual Meeting. Abstentions and broker non-votes are treated as present for quorum purposes.

How do I obtain more information about the Company?

A copy of our 2019 Annual Report is available on the website www.proxyvote.com. You may obtain, free of charge, a copy of our Corporate Governance Guidelines, our Code of Business Conduct and Ethics and the charters for our Audit, Compensation and Nominating and Corporate Governance Committees by writing to: Interactive Brokers Group, Inc., One Pickwick Plaza, Greenwich, CT 06830, Attn: Investor Relations; e-mail: investor-relations@interactivebrokers.com.

Directors’ Recommendation

Board Leadership Structure

The Board’s current leadership structure separates the positions of Chairman and Chief Executive Officer, and Dr. Harris serves as Lead Independent Director. Given the size and ownership structure of the Company as a controlled company, as defined by Nasdaq Stock Market LLC (“Nasdaq”) Rules, we believe that the current leadership structure is suitable for the Company.

The Board’s Role in Risk Oversight

It is management’s responsibility to manage risk and bring to the Board of Directors’ attention any material risks to the Company. The Board of Directors has oversight responsibility through its Audit Committee which oversees the Company’s risk policies and processes relating to the financial statements and financial reporting processes and the guidelines, policies and processes for mitigating those risks.

Board Meetings and Committees

Our Board held four meetings during our 2019 fiscal year. Each of our then serving directors attended at least 75% of the meetings of our Board and the committees of our Board on which he served during fiscal year 2019. Our directors are expected to attend annual meetings of stockholders at which they are nominees for election, Board meetings and meetings of the committees on which they serve, and to spend time needed and meet as frequently as necessary to properly discharge their responsibilities. All of our then serving board members attended our 2019 annual meeting of stockholders.

Our Board has established an audit committee, a compensation committee, and a nominating and corporate governance committee. The composition, duties and responsibilities of these committees are set forth below. In the future, our Board may establish other committees, as it deems appropriate, to assist it with its responsibilities. As a controlled company, we are not required by Nasdaq to have a compensation committee or a nominating and corporate governance committee composed entirely of independent directors.

Audit Committee

Our Audit Committee is comprised of Dr. Lawrence Harris (Chairman), Mr. Gary Katz and Mr. Philip Uhde, each of whom is an independent director within the meaning of the rules of Nasdaq and the SEC. Our Audit Committee operates pursuant to a written charter that is available on our website at http://investors.interactivebrokers.com. Dr. Harris is an “audit committee financial expert” as defined in the SEC rules. Each member of our Audit Committee is financially literate. The composition of our Audit Committee satisfies the requirements of the Nasdaq and the SEC.

Our Audit Committee is responsible for, among other things:

Our Compensation Committee is responsible for, among other things:

Compensation Discussion and Analysis

Compensation Philosophy and Objectives

We adhere to the philosophy that compensation of our executive officers should first and foremost be directly and materially linked to each executive officer’s individual performance and our overall performance. The objectives of our executive compensation program are (1) to enhance our long-term value, (2) to assist us in attracting and retaining high quality talent, (3) to reward past performance and motivate future performance and (4) to align executive officers’ long-term interests with those of our stockholders.

We believe that these practices provide our executive officers with incentives that are aligned with our conservative risk management policies. A substantial portion of executive compensation is in the form of long-term stock awards, which include vesting periods and cancellation conditions. These are designed not only to encourage long-term performance, but also to minimize the type of short-term risk-taking that might contravene our risk management policies. Our approach to compensation complements our practices of real-time risk assessment and daily measurement of financial performance in the various parts of its businesses, which also act as disincentives to excessive risk-taking.

Elements of Compensation

Although our executive officers and other key employees holding ownership interests in Holdings have benefited from the increased value of their ownership interests, they have historically received salary and performance-based bonuses and we expect to continue compensating them in this form. We believe that in order to attract and retain highly effective people we must maintain a flexible compensation structure, including base salary, cash bonuses and stock awards as described below. As stated above, we do not utilize a specific formula for allocating compensation among the various elements of total compensation. The relative amounts of cash bonus and stock awards were determined at the discretion of our Compensation Committee. Historically, Mr. Thomas Peterffy has taken no cash bonus or long-term incentives as he believes that his and his affiliates’ approximate 89.6% ownership of Holdings which, in turn, owns approximately 81.5% of IBG LLC, has provided sufficient incentive to align his interests with those of our common stockholders.

Base Salary. Base salary is structured to ensure that our executive officers are fairly and equitably compensated. Base salary is used to appropriately recognize and reward the experience and skills that employees bring to us and provides motivation for career development and enhancement. Base salary is designed to ensure that all employees continue to receive a basic level of compensation that reflects any acquired skills that are competently demonstrated and are consistently used at work.

Base salary for our executive officers is initially established based on the scope of their responsibilities and the applicable competitive market compensation paid by other companies for similar positions and is reviewed annually after employment. A single base salary level is established each year, applicable to all executive officers except our Chairman and our Vice Chairman. Because executive officers are partially and, sometimes, substantially compensated through the appreciation in their equity ownership, the base salary is kept at a relatively modest level in comparison to salaries generally believed to be paid to senior executives at many other firms in our industry. An executive officer’s base salary is not dependent upon our achievement of performance goals.

Bonuses. We maintain an executive cash bonus program to reward superior individual and financial performance for the year. Each year, an executive cash bonus pool is established, from which we pay annual cash bonuses to our executive officers upon the direction of our Compensation Committee. The amount of the pool is based on several factors, including the financial performance of the Company, our progress toward our strategic goals and the competitive environment for experienced executives. Executive bonuses are based on individual performance and on the financial performance of the Company, measured in a qualitative fashion. Specific individual and/or company performance goals or targets have historically not been used. Cash bonuses awarded to our executive officers in December 2019 for fiscal year 2019 performance ranged from 0% to approximately 538% of the executive officer’s 2019 base salary, amounting to an aggregate payout of $5,675,000. Our Chairman did not take a cash bonus in accordance with historical practices. The annual bonuses paid to our other executive officers for fiscal year 2019 performance are shown below in the Summary Compensation Table.

Long-Term Incentives. We utilize long-term stock awards to promote the success of each executive officer, motivate outstanding performance and encourage and reward employment longevity. Prior to our Initial Public Offering (the “IPO”), executive officers and other key employees had historically been granted equity ownership interests in IBG LLC and continue to hold such interests through their ownership of membership interests in Holdings.

We believe that compensation paid to executive officers should be closely aligned with our performance on a continuing and long-term basis and, thereby, with the interests of our stockholders. Toward this end, the Stock Incentive Plan provides for the granting of stock awards, which under the current terms gives rise to the issuance of common stock over approximately a six-year vesting schedule and ordinarily subject to continued employment with, and satisfaction of employment obligations to, the Company. Since the inception of the Stock Incentive

Plan, it has been our practice to make dividend equivalent payments on unvested stock awards in line with the common stock. It is not currently anticipated that we will grant, as part of executive compensation, stock appreciation rights or other forms of non-cash compensation except pursuant to the Stock Incentive Plan described below.

Pursuant to policies set by our Compensation Committee, base salary increases, cash bonuses and stock awards shall be awarded annually, following an evaluation of the individual’s and the Company’s performance for the year.

Compensation for Named Executive Officers During 2019

Historically Mr. Thomas Peterffy, as Chairman of our Compensation Committee, has ultimately determined compensation for all employees. With the Compensation Committee, Mr. Thomas Peterffy has traditionally set his own compensation as salary, capped at 0.2% of IBG LLC’s net income. During 2019, Mr. Thomas Peterffy was paid a salary of $800,000 by IBG LLC and no bonus in accordance with historical practices. With the intention to set a salary level safely below the cap as calculated for 2019, during 2020, Mr. Thomas Peterffy will be paid a salary of $800,000 by IBG LLC. We believe that the ownership by Mr. Thomas Peterffy and affiliates, through their direct and indirect ownership in Holdings, of a significant amount of the equity in IBG LLC aligns his interests with those of our common stockholders.

Mr. Earl H. Nemser’s compensation has historically included significantly lower overall compensation than the other executive officers, befitting the fact that Mr. Nemser works less than full-time with us, but his compensation has been mainly in salary and a relatively small long-term incentive award under the Stock Incentive Plan. Mr. Thomas Peterffy has made this determination based on the assessments described above under “Setting Executive Compensation.” During 2019, Mr. Nemser was paid a salary of $610,000 by IBG LLC and a bonus of $500,000 in accordance with these practices. Mr. Nemser also received an award under the Stock Incentive Plan valued at $550,000 for the year ended December 31, 2019. During 2020, Mr. Nemser will be paid a salary of $630,000 by IBG LLC.

Messrs. Milan Galik and Paul J. Brody and Dr. Thomas A. J. Frank, the Company’s Executive Vice President and Chief Information Officer, have historically been compensated in accordance with the policies discussed above under “Setting Executive Compensation” with a mixture of base salary, cash bonus and stock awards under the Stock Incentive Plan. Their 2019 base salary was $465,000, and each received an individual performance-based bonus. In addition to performance evaluations, consideration was given to the benefits derived from each individual’s existing ownership of membership interests in Holdings. Messrs. Galik and Brody and Dr. Frank received stock awards under the Stock Incentive Plan valued at $5,400,000, $2,670,000 and $1,000,000, respectively, for the year ended December 31, 2019.

The contributions of each of our executive officers that the Compensation Committee considered included: Mr. Milan Galik in his role as President and as newly appointed Chief Executive Officer substantially expanded his key role in the management of the Company over the execution of its strategy and in the ongoing development of software and systems for our electronic brokerage platform, driving the growth of our business. Mr. Galik’s performance and contribution to the achievement of the Company’s financial goals, as well as his role as Chief Executive Officer and President, merited a higher bonus in 2019 than the other executive officers of the Company, including Mr. Paul J. Brody and Dr. Thomas A.J. Frank, in the determination of the Compensation Committee. Mr. Brody made ongoing efforts with respect to building and maintaining strong financial and operational controls, a prudent liquidity program, banking relationships, credit ratings and interaction with domestic and foreign financial regulators. Dr. Frank continued to enhance the Company’s risk management and global technical infrastructure. Their 2020 base salary has been increased to $480,000. Each of Messrs. Galik and Brody and Dr. Frank is expected to receive an award under the Stock Incentive Plan in 2020 based on each executive officer’s anticipated future contribution to our success. The 2019 stock awards under the Stock Incentive Plan were consistent with the above-mentioned policies and reflected the Compensation Committee’s assessment of each executive’s leadership, performance and contribution to the building of our Company.

All salaries and bonuses will be paid by IBG LLC or one of its operating subsidiaries. No employee of IBG LLC will be paid any separate or additional amount for their services as employees of the Company. In addition to the

foregoing, each of the executive officers, as a result of their direct and/or indirect ownership of membership interests in Holdings, received indirect distributions from IBG LLC in part for the purpose of funding their income taxes due on their direct and/or indirect proportionate share of Holdings’ proportionate share of IBG LLC’s taxable income.

401(k) Plan

We offer substantially all employees of our U.S. based subsidiaries who have met minimum service requirements the opportunity to participate in a defined contribution retirement plan qualifying under the provisions of Section 401(k) of the Internal Revenue Code. The general purpose of this plan is to provide employees with an incentive to make regular savings in order to provide additional financial security during retirement. The plan provides for IBG LLC to match 50% of the employees’ pretax contribution, up to a maximum of 10% of eligible earnings. Employees are vested in the matching contribution incrementally over six years.

Severance Arrangements

None of our executive officers have employment agreements and none are subject to severance arrangements. A portion of our executive officers’ equity ownership in us is in the form of Holdings membership interests and stock awards under the Stock Incentive Plan. Stock awards for which restrictions are still applicable may under certain conditions be immediately cancelled upon the termination of employment for any reason.

Perquisites

Our executive officers receive only the fringe benefits normally provided to all other employees, such as health, dental, life, hospitalization, surgical, major medical and disability insurance, participation in our 401(k) plan, paid time off, and other similar company-wide benefits which may be in effect from time to time for all other employees. Other than the standard employee benefits, we do not provide additional perquisites, personal direct or indirect benefits, or use any separate set of standards in determining the benefits for our executive officers. We believe that our base salary and total compensation package are reasonable and competitive in the industry, and we have demonstrated that we are able to hire and retain talented executives without offering additional perquisites.

It is our philosophy that each executive officer may determine, within the limits of his or her own compensation, whether or not to personally purchase non-reimbursable luxury travel, private flights (except for our Chairman’s business travel), housing, security systems, car service, club memberships, financial planning services, or other such goods and services, including those which are sometimes provided as executive perquisites by other companies, but not offered by us. This is consistent with our general operating principles.

Accounting for Stock-Based Compensation

The Company follows Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 718, “Compensation—Stock Compensation” (“ASC Topic 718”), to account for its stock-based compensation plans. ASC Topic 718 requires all share-based payments to employees to be recognized in the financial statements using a fair value-based method. Grants, which are denominated in U.S. dollars, are communicated to employees in the year of grant, thereby establishing the fair value of each grant. The fair value of stock awards granted to employees are generally expensed as follows: 50% in the year of grant in recognition of the plans’ post-employment provisions (as described below) and the remaining 50% over the related vesting period utilizing the “graded vesting” method permitted under ASC Topic 718. In the case of “retirement eligible” employees (those employees older than 59), 100% of stock awards are expensed when granted.

Stock awards granted under stock-based compensation plans are subject to the plans’ post-employment provisions in the event an employee ceases employment with the Company. The plans provide that employees who discontinue employment with the Company without cause and continue to meet the terms of the plans’ post-employment provisions will be eligible to earn 50% of previously granted but not yet earned stock awards, unless the employee is over the age of 59, in which case the employee would be eligible to receive 100% of previously granted but not yet earned stock awards.

We have never issued stock options to our employees.

Advisory Vote on Executive Compensation

At the 2019 Annual Meeting, pursuant to Section 14A of the 1934 Act, we submitted a proposal to stockholders for a (nonbinding) advisory vote to approve the compensation of our executive officers as disclosed in the Proxy Statement for the 2019 Annual Meeting. This advisory vote on executive compensation, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on the compensation of our executive officers. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our executive officers and the principles, policies and practices described in this proxy statement. Our stockholders approved this proposal with more than 96% of the total votes cast voting in favor.

At the 2017 Annual Meeting, we also asked our stockholders to indicate if we should hold an advisory vote on the compensation of our executive officers every one, two or three years, with our board of directors recommending an advisory vote every two years. At our 2017 Annual Meeting more than 90% of the total votes cast were in favor of an advisory vote every two years. In accordance with the two-year schedule, we will be asking our stockholders to approve, on an advisory basis, the compensation of our executive officers as will be disclosed in the Proxy Statement for the 2021 Annual Meeting.

Also excluded from the Summary Compensation Table are dividend equivalent payments on unvested stock awards, under the terms of the Stock Incentive Plan, paid to our executive officers. Messrs. Nemser, Galik and Brody and Dr. Frank received $9,898, $134,130, $73,933 and $28,255, respectively, in dividend equivalent payments with respect to the year ended December 31, 2019; $10,854, $147,896, $85,528 and $33,759 respectively, in dividend equivalent payments with respect to the year ended December 31, 2018; approximately $13,682, $177,523, $104,807 and $43,365, respectively, in dividend equivalent payments with respect to the year ended December 31, 2017.

Pay Ratio Disclosure

As required by Section 953(b) of the Dodd-Frank Act, we are providing the following information about the relationship of the annual total compensation of our Chief Executive Officer and President, Mr. Milan Galik, and the annual total compensation of our median employee. For the year ended December 31, 2019:

To determine the median of the annual total compensation of all employees of the Company (other than our Chief Executive Officer and President), we identified our total employee population as of December 31, 2019, which consisted of approximately 1,643 individuals, all of which were full-time equivalent employees.

We determined the median based on each employee’s annual total compensation as of December 31, 2019. Annual total compensation consisted of base pay, cash bonuses, the fair value of stock awards granted under the Stock Incentive Plan at the grant date, and dividend equivalent payments on unvested stock awards. The annual total compensation of the median employee was calculated in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K.

Executive Employment Agreements

Historically, we have not entered into employment agreements with our executive officers, and we do not plan on entering into employment agreements at this time. We do maintain non-disclosure, non-competition and non-solicitation agreements currently in effect between our subsidiaries and our executive officers and other employees.

Stock Incentive Plan

Under the Stock Incentive Plan up to 30 million shares of common stock may be issued to satisfy vested stock awards granted to directors, officers, employees, contractors and consultants of the Company and its subsidiaries. The purpose of the Stock Incentive Plan is to promote the Company’s long-term financial success by attracting, retaining and rewarding eligible participants.

As a result of the Company's organizational structure as described in the “Business – Our Organizational Structure” in Part 1, Item1 of our Annual Report on Form 10-K for the year ended December 31, 2019, there is no dilutive effect upon ownership of common stockholders of issuing shares under the Stock Incentive Plan. The issuances do not dilute the book value of the ownership of common stockholders because the stock awards are granted at market value, and upon their vesting and the related issuance of shares of common stock, the ownership of IBG, Inc. in IBG LLC, increases proportionately to the shares issued. As a result of such proportionate increase in share ownership, the dilution upon issuance of common stock is borne by IBG LLC’s majority member (i.e., noncontrolling interest), Holdings, and not by IBG, Inc. or its common stockholders. Additionally, dilution of earnings that may take place after issuance of common stock is reflected in the earnings per share (“EPS”) reported in the Company’s financial statements. The EPS dilution can be neither estimated nor projected, but historically it has not been material.

The Stock Incentive Plan is administered by the Compensation Committee of the Company’s Board of Directors. The Compensation Committee has discretionary authority to determine the eligibility to participate in the Stock

Incentive Plan and establishes the terms and conditions of the stock awards, including the number of stock awards granted to each participant and all other terms and conditions applicable to such stock awards in individual grant agreements. Stock awards are expected to be made primarily through grants of stock awards. Stock Incentive Plan stock awards are subject to issuance over time. All previously granted but not yet earned stock awards may be cancelled by the Company upon the participant’s termination of employment or violation of certain applicable covenants prior to issuance, unless determined otherwise by the Compensation Committee.

The Stock Incentive Plan provides that, upon a change in control, the Compensation Committee may, at its discretion, fully vest any granted but not yet earned stock awards under the Stock Incentive Plan, or provide that any such granted but not yet earned awards will be honored or assumed, or new rights substituted by the new employer on a substantially similar basis and on terms and conditions substantially comparable to those of the Stock Incentive Plan.

We generally grant stock awards on or about December 31 of each year, to specific employees as part of the Company’s Stock Incentive Plan. We granted stock awards of 1,374,560 in 2019 under the Stock Incentive Plan.

Under applicable tax law, we are required to withhold an amount based on the value of the shares upon their issuance, and remit the withheld amount to the Internal Revenue Service (“IRS”) and other taxing authorities. To effect that withholding, we may redeem a portion of the shares with an aggregate fair market value equal to the amount of taxes we are required to withhold and remit. For instance, if 1,000 shares would become issuable and we were required to withhold for federal taxes an amount equal to 40% of the value, we would redeem 400 shares and the employee would reclaim 600 shares. The source of funds for the amount to be remitted to the IRS would be a redemption by IBG LLC of a corresponding number of our interests in IBG LLC. Alternatively, we may elect to effect the withholding by facilitating the sale of a portion of the shares, on behalf of employees, in the open market, and the proceeds of such sales would be remitted to the IRS and other taxing authorities.

Stock awards granted under the Stock Incentive Plan are subject to the plan’s post-employment provisions in the event an employee ceases employment with the Company. The Stock Incentive Plan provides that employees who discontinue employment with the Company without cause and continue to meet the terms of the plans’ post-employment provisions will be eligible to earn 50% of previously granted but not yet earned stock awards, unless the employee is over the age of 59, in which case the employee would be eligible to receive 100% of previously granted but not yet earned stock awards.

the common stock on the date of grant), subject to straight-line vesting over a five year period, and non-employee chairmen of committees of our Board are compensated with an additional annual retainer of $25,000 per committee. We reserve the right to change the manner and amount of compensation to our non-employee directors at any time. Stock awards granted under the Stock Incentive Plan to non-employee directors carry the same cancellation provisions as those granted to employees, which are described above.

Beneficial Ownership of Directors, Executive Officers and Owners of More Than Five Percent

Holdings currently holds, through its ownership of all of the outstanding shares of our Class B common stock, approximately 81.5% of the combined voting power of the outstanding shares of common stock. While our Class B common stock is owned by Holdings, Mr. Thomas Peterffy, through his indirect ownership of the voting membership interests in Holdings, is able to exercise control over all matters requiring the approval of our stockholders, including the election of our directors and the approval of significant corporate transactions.

The following table sets forth the beneficial ownership of common stock as of March 9, 2020 by each of our directors and executive officers, by all our directors and executive officers as a group, and of each beneficial owner, who is not our director or officer, of more than 5% of common stock as of December 31, 2019.

The amounts and percentages of common stock beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under the rules of the SEC, a person is deemed to be a beneficial owner of a security if that person has or shares voting power, which includes the power to vote or to direct the voting of such security, or investment power, which includes the power to dispose of or to direct the disposition of such security and if that person has the right to acquire such security within 60 days of the filing of this proxy. Unless otherwise indicated below, each beneficial owner named in the table below has sole voting and sole investment power with respect to all shares beneficially owned. Because the Holdings membership interests are not directly exchangeable into shares of common stock, none of our executive officers and directors may be deemed to own shares of common stock except as set forth below. Mr. Peterffy may be deemed to own all of the shares of Class B common stock. The following table is based on 76,751,240 shares of common stock and 100 shares of Class B common stock outstanding as of March 9, 2020:

membership interests in return. The Exchange Agreement provides for future redemptions of member interests and for the purchase of member interests in IBG LLC by IBG, Inc. from Holdings, which could result in IBG, Inc. acquiring the remaining member interests in IBG LLC that it does not own. The Exchange Agreement, as amended June 6, 2012 and July 23, 2015, provides that the Company may facilitate the redemption by Holdings of interests held by its members through the issuance of shares of common stock through a public offering in exchange for the interests in IBG LLC being redeemed by Holdings. On an annual basis, each holder of a membership interest may request that Holdings redeem the liquefiable portion of that holder’s interest. We expect Holdings to use the net proceeds it receives from such sales to redeem an identical number of Holdings membership interests from the requesting holders. A copy of the First Amendment to the Exchange Agreement was filed as Exhibit 10.1 to the Form8-K filed by the Company on June 6, 2012 and a copy of the Second Amendment to the Exchange Agreement was filed as Exhibit 10.1 to the Quarterly Report on Form 10-Q for the Quarterly Period Ended September 30, 2015 filed by the Company on November 9, 2015, both of which are incorporated herein by reference. The redemption price for the membership interests in Holdings depends on the timing at which the redemption is made.

A copy of the Exchange Agreement was filed as Exhibit 10.3 to the Quarterly Report on Form 10-Q for the Quarterly Period Ended September 30, 2009 filed by the Company on November 9, 2009 and is incorporated herein by reference.

Sales of common stock and the application of the net proceeds to acquire IBG LLC membership interests are expected to have a negligible effect on the existing holders of common stock, as the holders of common stock would then own a larger portion of IBG LLC. Such transactions will have the effect of diluting your percentage ownership in us. However, because we will acquire an increased percentage ownership in IBG LLC over time as a result of such transactions, such transactions will not impact your effective percentage ownership of the economics of the underlying IBG LLC business.

Holdings, with the consent of Mr. Thomas Peterffy and our Board, has the right to cause the holders of Holdings membership interests to have all or a portion of their interests redeemed at any time. Such redemptions would be financed in the same manner as the scheduled redemptions described above.

Tax Receivable Agreement

In connection with the IPO, we purchased membership interests in IBG LLC from Holdings for cash. In addition, IBG LLC membership interests held by Holdings may be purchased by us in the future in connection with offerings by us of shares of common stock. Our purchases of IBG LLC membership interests have resulted, and future purchases may result, in increases in the tax basis of the tangible and intangible assets of IBG LLC attributable to our interest in IBG LLC that otherwise would not have been available, although the IRS may challenge all or part of that tax basis increase or our ability to amortize all or part of that increased tax basis, and a court could sustain such a challenge by the IRS. These increases in tax basis, if sustained, may reduce the amount of taxable income that we are required to recognize as the result of our ownership of membership interests in IBG LLC in the future.

Concurrently with the IPO, we entered into a tax receivable agreement with Holdings that provides for the payment by us to Holdings of 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax or franchise tax that we actually realize as a result of these increases in tax basis and of certain other tax benefits related to our entering into the tax receivable agreement, including tax benefits attributable to payments under the tax receivable agreement. We will retain 15% of the projected tax benefits.

If either immediately before or immediately after any purchase or the related issuance of our stock, the Holdings members own or are deemed to own, in the aggregate, more than 20% of our outstanding stock, then all or part of any increase in the tax basis of goodwill may not be amortizable and, thus, our ability to realize the annual tax savings that otherwise would have resulted if such tax basis were amortizable may be significantly reduced. Although the Holdings members are prohibited under the exchange agreement from purchasing shares of common stock, grants of our stock to employees and directors who are also members or related to members of Holdings and the application of certain tax attribution rules, such as among family members and partners in a partnership, could result in Holdings members being deemed for tax purposes to own shares of common stock.

In order to mitigate the risk to us of an IRS challenge to the tax basis increase, Holdings and its members will indemnify us for any additional taxes we owe if the IRS or other taxing authorities successfully challenge the

basis increase. In addition, if the IRS or other taxing authorities successfully challenge the tax basis increase, any subsequent payments we are required to make under the tax receivable agreement will be reduced accordingly.

For purposes of the tax receivable agreement, cash savings in income and franchise tax will be computed by comparing our actual income and franchise tax liability to the amount of such taxes that we would have been required to pay had there been no increase in the tax basis of the tangible and intangible assets of IBG LLC attributable to our acquisition of our interest in IBG LLC, and had we not entered into the tax receivable agreement. The tax receivable agreement will, unless we exercise our right to terminate the tax receivable agreement for an amount based on an agreed value of payments remaining to be made under the agreement, terminate upon the earlier of (i) the end of the taxable year that includes the 50th anniversary of our initial acquisition of membership interests in IBG LLC, or (ii) the end of the taxable year that includes the 16th anniversary of the date upon which all rights of sale and exchange granted under the exchange agreement have terminated.

Our ability to achieve tax benefits from any increase in the tax basis attributable to our interest in IBG LLC resulting from our acquisition of membership interests in IBG LLC and the payments to be made under the tax receivable agreement with respect thereto depend upon a number of factors, including the law as in effect at the time of a purchase by us of membership interests in IBG LLC or a payment under the tax receivable agreement, the timing of purchases, the fair market value of membership interests in IBG LLC at the time of a purchase, the extent to which such purchases are taxable, the impact of the increase in the tax basis on our ability to use foreign tax credits and the rules relating to the amortization of intangible assets, the composition of IBG LLC’s assets at the time of a purchase, and the amount and timing of our income and of payments under the tax receivable agreement. Depending upon the outcome of these factors, as a result of the size of the increases in the tax basis of the tangible and intangible assets of IBG LLC and its subsidiaries, the payments that we may make to Holdings could be substantial.

Legal Representation

We utilize a number of law firms as independent counsel, including Dechert LLP, to which Mr. Earl H. Nemser, our Vice Chairman and one of our directors, serves as an unpaid Independent Advisor. Mr. Nemser served as Special Counsel to Dechert LLP from January 2005 to October 2018.

Margin Accounts at Interactive Brokers LLC

Our subsidiary, Interactive Brokers LLC (“IB LLC”), may extend credit in the ordinary course of business to certain of our directors, officers, and their affiliates in connection with margin loans. Such loans (i) are made in the ordinary course of business, (ii) are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to IB LLC, and (iii) do not involve more than the normal risk of collectability or present other unfavorable features.

Review, Approval or Ratification of Transactions with Related Persons

We review all relationships and transactions in which the Company and our directors and executive officers or their immediate family members are participants to determine whether such persons have a direct or indirect material interest. Our Audit Committee, our Chief Executive Officer and the General Counsel of the Company are responsible for the development and implementation of processes and controls to obtain information from the directors and executive officers with respect to related person transactions and for then determining, based on the facts and circumstances, whether the Company or a related person has a direct or indirect material interest in the transaction. In addition, our Nominating and Corporate Governance Committee monitors and reviews any issues regarding the “independence” of directors or involving potential conflicts of interest, and evaluates any change of status or circumstance with respect to a director and determines the propriety of the director’s continued service in light of that change.
