We are filing this Amendment to include the information required by Part III and Part IV of Form 10-K to be filed as part of the Original Report as we will not be filing our definitive proxy statement within 120 days of the end of our fiscal year ended December 31, 2018. Except as set forth in this Amendment, no other changes have been made to the Original Report. Unless expressly stated, this Amendment does not reflect events occurring after the filing of the Original Report and does not modify or update in any way the disclosures contained in the Original Report, which speak as of the date of the Original Report.

PART III.





ITEM 10. DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE





Directors





Our business affairs are managed under the direction of our board of directors, which is currently composed of five members. Our nominating and corporate governance committee considers issues of character, integrity, judgment, diversity (including, but not limited to, diversity of gender, ethnicity, race, international background and life experience), age, independence, skills, education, expertise, business acumen, business experience, length of service, understanding of the Company’s business, and other commitments in reviewing and making recommendations to our board of directors regarding the composition and size of the board of directors and determining the relevant criteria for membership on our board of directors.





Four of our directors are independent within the meaning of the listing standards of the New York Stock Exchange. At the 2018 annual meeting of stockholders, the proposal to declassify our board of directors was approved. This resulted in the entire board being elected annually for one-year terms on a “rolling” basis beginning with the 2018 annual meeting such that each director serving as of immediately prior to the opening of the meeting will serve through the remainder of his term and each director elected or appointed thereafter will serve a one-year term expiring on the next annual meeting of stockholders.





The names of our directors and their ages (as of the date of this Form 10-K/A), positions, term expiration years and biographies as of the date of this Form 10-K/A are set forth below.

Board Leadership Structure





Mr. Chen currently serves as both Chairman of our Board of Directors and our Chief Executive Officer.

Our board determined that it would be beneficial to have a Lead Independent Director to, among other things, preside over executive sessions of the independent directors, which provides our board with the benefit of having the perspective of entirely independent directors.

As lead independent director, Dr. Salsbury presides over periodic meetings of our independent directors, serves as a liaison between our Chairman of our board of directors and the independent directors, and performs such additional duties as our board of directors may otherwise determine and delegate.

No director attended fewer than 75% of the aggregate of (i) the total number of meetings of our board of directors held during the period for which he or she has been a director and (ii) the total number of meetings held by all committees of our board of directors on which he or she served during the periods that he or she served. Although we do not have a formal policy regarding attendance by members of our board of directors at annual meetings of stockholders, we encourage, but do not require, our

Our nominating and corporate governance committee operates under a written charter that satisfies the applicable listing standards of the New York Stock Exchange. A copy of the charter of our nominating and corporate governance committee is available on our website at http://investors.a10networks.com. During 2018, our nominating and corporate governance committee held one (1) meeting and acted by written consent one (1) time.


Communications with the Board of Directors





Interested parties wishing to communicate with our board of directors or with an individual member or members of our board of directors may do so by writing to our board of directors or to the particular member or members of our board of directors, and mailing the correspondence to our General Counsel at A10 Networks, Inc., 3 West Plumeria Drive, San Jose, CA 95134, Attn: General Counsel. Each communication should set forth (i) the name and address of the stockholder, as it appears on our books, and if the shares of our common stock are held by a nominee, the name and address of the beneficial owner of such shares, and (ii) the number of shares of our common stock that are owned of record by the record holder and beneficially by the beneficial owner. Our General Counsel, in consultation with appropriate members of our board of directors as necessary, will review all incoming communications and, if appropriate, such communications will be forwarded to the member or members of our board of directors to whom such communication was directed, or if none is specified, to the Chairman of our board of directors.


Corporate Governance Guidelines and Code of Business Conduct and Ethics





Our board of directors has adopted Corporate Governance Guidelines that address items such as the qualifications and responsibilities of our directors and director candidates and corporate governance policies and standards applicable to us in general. In addition, our board of directors has adopted a Code of Business Conduct and Ethics that applies to all of our employees, officers and directors, including our Chief Executive Officer, Chief Financial Officer, and other executive and senior financial officers. The full text of our Corporate Governance Guidelines and our Code of Business Conduct and Ethics is posted on the Corporate Governance portion of our website at http://investors.a10networks.com. We will post amendments to our Code of Business Conduct and Ethics or waivers of our Code of Business Conduct and Ethics for directors and executive officers on the same website.


Risk Management





Risk is inherent with every business and we face a number of risks, including strategic, financial, business and operational, legal and compliance, and reputational. We have designed and implemented processes to manage risk in our operations. Management is responsible for the day-to-day management of risks the company faces, while our board of directors, as a whole and assisted by 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 appropriate and functioning as designed.





Our board of directors believes that open communication between management and our board of directors is essential for effective risk management and oversight. Our board of directors meets with our Chief Executive Officer and other members of the senior management team at quarterly meetings of our board of directors, where, among other topics, they discuss strategy and risks facing the company, as well as at such other times as they deemed appropriate.





While our board of directors is ultimately responsible for risk oversight, our board committees assist our board of directors in fulfilling its oversight responsibilities in certain areas of risk. Our audit committee assists our board of directors in fulfilling its oversight responsibilities with respect to risk management in the areas of internal control over financial reporting and disclosure controls and procedures, legal and regulatory compliance, and discusses with management and the independent auditor guidelines and policies with respect to risk assessment and risk management. Our audit committee also reviews our major financial risk exposures and the steps management has taken to monitor and control these exposures. Our audit committee also monitors certain key risks on a regular basis throughout the fiscal year, such as risk associated with internal control over financial reporting and liquidity risk. Our nominating and corporate governance committee assists our board of directors in fulfilling its oversight responsibilities with respect to the management of risk associated with board organization, membership and structure, and corporate governance. Our compensation committee assesses risks created by the incentives inherent in our compensation policies. Finally, our full board of directors reviews strategic and operational risk in the context of reports from the management team, receives reports on all significant committee activities at each regular meeting, and evaluates the risks inherent in significant transactions.

Section 16(a) Beneficial Ownership Reporting Compliance





Section 16(a) of the Exchange Act requires that our executive officers and directors, and persons who own more than 10% of our common stock, file reports of ownership and changes of ownership with the SEC. Such directors, executive officers and 10% stockholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file.





SEC regulations require us to identify anyone who filed a required report late during the most recent fiscal year. Based on our review of forms we received, or written representations from reporting persons stating that they were not required to file these forms, we believe that during our fiscal ended December 31, 2018, all Section 16(a) filing requirements were satisfied on a timely basis.








ITEM 11. EXECUTIVE COMPENSATION


Processes and Procedures for Compensation Decisions





Our compensation committee is responsible for the executive compensation programs for our executive officers and reports to our board of directors on its discussions, decisions and other actions. Our compensation committee makes recommendations to our board of directors regarding compensation for our Chief Executive Officer. The independent members of our board of directors make the final decisions regarding executive compensation for our Chief Executive Officer. Typically, our Chief Executive Officer makes recommendations to our compensation committee regarding, and often attends committee meetings relating to the determination of, compensation for the respective executive officers that report to him, except that our Chief Executive Officer does not make recommendations as to his own compensation. Our Chief Executive Officer makes recommendations to our compensation committee regarding short- and long-term compensation for all executive officers (other than himself) based on our results, an individual executive officer’s contribution toward these results and performance toward individual goal achievement. Our compensation committee then reviews the recommendations and other data and makes decisions as to total compensation for each executive officer other than the Chief Executive Officer, as well as each individual compensation component.





Our compensation committee is authorized to retain the services of one or more executive compensation advisors, as it sees fit, in connection with the establishment of our compensation programs and related policies. In 2018, Compensia, a national compensation consultant, was engaged by our compensation committee to provide information, recommendations and other advice relating to executive compensation. As part of the engagement, Compensia assisted our compensation committee with developing an appropriate group of peer companies to help us determine the appropriate level of overall compensation for our executive officers, as well as assessed each element of compensation with a goal of ensuring that the compensation we offer to our executive officers is competitive and fair.


Fiscal 2018 Summary Compensation Table





The following table provides information regarding the total compensation for services rendered in all capacities that was earned by each individual who served as our principal executive officer at any time in 2018 and our two other most highly compensated executive officers who were serving as executive officers as of December 31, 2018. These individuals were our named executive officers (each, an “NEO” and together, the “NEOs”) for 2018.

|(5) | Mr. White became a NEO in 2018. The amount reported under the Bonus column represents the sign-on bonus he received pursuant to the terms of his offer letter and the amount reported under the Non‐Equity Incentive Plan Compensation column represents the bonus paid to him under the 2018 Executive Cash Incentive Plan in March 2019.

Non-Equity Incentive Plan Compensation





For our 2018 fiscal year, Messrs. Constantino and White were eligible to receive annual cash bonuses based 80% on corporate performance goals and 20% on individual performance goals under our 2018 Executive Cash Incentive Plan, as approved by the compensation committee. The 2018 Executive Cash Incentive Plan was established under and subject to the terms of our Executive Incentive Compensation Plan, as described in further detail below. Mr. Constantino’s target bonus opportunity for our 2018 fiscal year was equal to 65% of his 2018 base salary and Mr. White’s target bonus opportunity for our 2018 fiscal year was equal to 66.67% of his 2018 base salary. The corporate performance goals under such plan related to our revenue and non‐GAAP operating income for 2018. Generally, the portion of the plan based on corporate performance goals would result in funding of bonuses upon the achievement of threshold levels of both revenue and non‐GAAP operating income as specified in a performance goal matrix approved by the compensation committee. The maximum amount that could be earned on the individual performance goals was 100% and the maximum amount that could be earned on the corporate performance goals was 150%.





In early 2019, our Chief Executive Officer evaluated, and presented to the compensation committee, the progress made towards achieving the corporate and individual performance goals in accordance with the terms of the Executive Cash Incentive Plan and made a recommendation to our compensation committee regarding the bonus amount for each of Messrs. Constantino and White based on this evaluation. The bonuses for Messrs. Constantino and White, as determined pursuant to the terms of the Executive Cash Incentive Plan and our Chief Executive Officer’s recommendation, were approved on March 4, 2019. For the 2018 fiscal year, Mr. Constantino earned a cash bonus of $44,053 for achievement of his individual performance goals and Mr. White earned a cash bonus of $47,613  for achievement of his individual performance goals. The amount earned on corporate performance goals was $0 because the corporate performance goals were not met.





Mr. Chen is not eligible to receive an annual cash bonus.


Emerging Growth Company Status





We are an “emerging growth company,” as defined in the JOBS Act. As an emerging growth company, we are exempt from certain requirements related to executive compensation, including the requirements to hold nonbinding advisory votes on executive compensation and to provide information relating to the ratio of total compensation of our Chief Executive Officer to the median of the annual total compensation of all of our employees, each as required by the Investor Protection and Securities Reform Act of 2010, which is part of the Dodd-Frank Act.





Non-qualified Deferred Compensation





Our NEOs did not participate in, or earn any benefits under, a non-qualified deferred compensation plan sponsored by us during the fiscal year ended December 31, 2018.

Change in Control and Severance Agreements





We entered into a Change in Control and Severance Agreement (each, an “Agreement” and together, the “Agreements”) with each of our NEOs.





Each NEO’s Agreement provides that if, after the executive completes at least one year of employment with us or if promoted to an executive position, completes at least one year in an executive role and (a) we terminate the executive’s employment with us for any reason other than for cause and not due to the executive’s death or disability, or (b) the executive resigns for Good Reason (as defined in the Agreement), and in each case the termination does not occur during the Change in Control Period (as defined in the Agreement), the executive will receive the following severance benefits: (i) continuing payments of salary severance for a period of 12 months (in the case of Mr. Chen) or nine months (in the case of the other NEOs), and (ii) continuing payments to reimburse the executive for COBRA continuation coverage for a period of up to 12 months (in the case of Mr. Chen) or nine months (in the case of the other NEOs).





Each Agreement further provides that if we terminate the executive’s employment with us for any reason other than cause and not due to the executive’s death or disability, or the executive resigns for Good Reason, and in each case the termination occurs during the Change in Control Period, the executive will receive the following severance benefits: (i) a lump sum cash payment equal to 150% (in the case of Mr. Chen) or 100% (in the case of the other NEOs) of the greater of the executive’s salary in effect as of immediately prior to his employment termination or the Change in Control, (ii) a lump sum cash payment equal to 150% (in the case of Mr. Chen) or 100% (in the case of the other NEOs) of the greater of the executive’s target bonus in effect for the year in which the executive’s employment terminates or the Change in Control occurs, (iii) continuing payments to reimburse the executive for COBRA continuation coverage for a period of up to 18 months (in the case of Mr. Chen) or 12 months (in the case of the other NEOs), and (iv) 100% accelerated vesting of the executive’s outstanding equity awards, with any applicable performance goals considered achieved at the target levels.





In order to receive the severance benefits under the Agreement, the executive must sign and not revoke a release of claims in our favor and comply with confidentiality obligations.





As defined in the Agreements, “Cause” generally means the executive’s (i) repeated failure to perform his duties and responsibilities to the Company or abide in all material respects with the Company’s policies after receiving written notice, (ii) engagement in illegal conduct injurious to the Company in any material respect, (iii) material violation or material breach of his confidential information and invention agreement with the Company that is not cured within 20 days of written notice or is incapable of cure, or (iv) conviction or plea of no contest to a felony (other than motor vehicle offenses that do not materially impair the executive’s performance of his employment duties) or any crime involving fraud, embezzlement or other offense involving moral turpitude, and/or committing any act of embezzlement, dishonesty or fraud against or the misappropriation of material property belonging to the Company.





As defined in the Agreements, “Change in Control Period” generally means, subject to the occurrence of a Change in Control, the period beginning on the date that an agreement to enter into such Change in Control is signed and executed, and ending on the date 12 months following such Change in Control. As will be defined in the Agreements, “Change in Control” generally means the occurrence of any of the following events: (i) a change in our ownership that occurs on the date that any one person or persons acting as a group (“Person”), acquires ownership of our stock that, together with the stock already held by such Person, constitutes more than 50% of the total voting power of our stock; (ii) a change in our effective control that occurs on the date that a majority of members of our board of directors is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of our board of directors prior to the date of the appointment or election; or (iii) a change in the ownership of a substantial portion of our assets that occurs on the date that any Person acquires (or has acquired during a 12-month period) assets from us with a total gross fair market value equal to or more than 50% of the total gross fair market value of all of our assets immediately prior to such acquisition(s), excluding any transfer to an entity that is controlled by our stockholders immediately after the transfer and any transfer of assets by us to an entity, 50% or more of the total value or voting power of which is owned, directly or indirectly, by us. For purposes of this definition, gross fair market value means the value of our assets, or the value of our assets being disposed of, determined without regard to any liabilities associated with such assets.





As defined in the Agreements, “Good Reason” generally means the executive’s voluntary termination of employment with us within 90 days following the expiration of our cure period following one or more of the following occurring without the executive’s prior consent: (i) a material reduction in the executive’s gross base salary other than in connection with a similar reduction for all similarly-situated employees; (ii) a material reduction in the executive’s authority, duties, or responsibilities; or (iii) a relocation of the executive’s principal place of work to

a location that is more than 50 miles from his current principal work site for us. The executive may not resign for Good Reason without first providing us with notice within 60 days of the initial existence of the condition that he believes constitutes Good Reason identifying the grounds for Good Reason and a reasonable cure period of at least 30 days following the date of such notice, during which such grounds must not have been cured.


Executive Incentive Compensation Plan





In March 2014, our board of directors adopted an Executive Incentive Compensation Plan, referred to as our Bonus Plan. Our Bonus Plan allows our compensation committee to provide cash incentive awards to selected employees, including our NEOs, based upon performance goals established by our compensation committee.





Under the Bonus Plan, our compensation committee determines the performance goals applicable to awards, which goals may include, without limitation: attainment of research and development milestones, sales bookings, business divestitures and acquisitions, cash flow, cash position, earnings (which may include any calculation of earnings, including but not limited to earnings before interest and taxes, earnings before taxes, earnings before interest, taxes, depreciation and amortization and net earnings), earnings per share, net income, net profit, net sales, operating cash flow, operating expenses, operating income, operating margin, overhead or other expense reduction, product defect measures, product release timelines, productivity, profit, return on assets, return on capital, return on equity, return on investment, return on sales, revenue, revenue growth, sales results, sales growth, stock price, time to market, total stockholder return, working capital, and individual objectives such as peer reviews or other subjective or objective criteria. Performance goals that include the Company’s financial results may be determined in accordance with U.S. generally accepted accounting principles, or GAAP, or such financial results may consist of non-GAAP financial measures and any actual results may be adjusted by our compensation committee for one-time items or unbudgeted or unexpected items when determining whether the performance goals have been met. The goals may be on the basis of any factors our compensation committee determines relevant, and may be adjusted on an individual, divisional, business unit or company-wide basis. Any criteria used may be measured on such basis as our compensation committee determines. The performance goals may differ from participant to participant and from award to award.





Our compensation committee may, in its sole discretion and at any time, increase, reduce or eliminate a participant’s actual award, and/or increase, reduce or eliminate the amount allocated to the bonus pool for a particular performance period. The actual award may be below, at or above a participant’s target award, in our compensation committee’s discretion. Our compensation committee may determine the amount of any reduction on the basis of such factors as it deems relevant, and it is not required to establish any allocation or weighting with respect to the factors it considers.





Actual awards are paid in cash (or its equivalent) in a single lump sum only after they are earned and approved by our compensation committee. Unless otherwise determined by our compensation committee, to earn an actual award, a participant must be employed by the Company (or an affiliate of the Company) through the date the bonus is paid. Payment of bonuses occurs as soon as administratively practicable after they are earned, but no later than the dates set forth in the Bonus Plan.





Our board of directors has the authority to amend, alter, suspend or terminate the Bonus Plan provided such action does not alter or impair the existing rights of any participant with respect to any earned bonus.


Retirement Plan





We maintain a tax-qualified 401(k) retirement plan for all employees who satisfy certain eligibility requirements under the plan. The plan provides eligible employees with an opportunity to save for retirement on a tax-advantaged basis. Participants of our 401(k) plan are able to defer a percentage of their eligible compensation, subject to applicable annual Internal Revenue Code and plan limits. All participants’ interests in their deferrals are 100% vested when contributed. We also provide matching contributions under our 401(k) plan that generally vest over a 4-year period based on the participant’s employment. The Company matches 50% of the first 6% of eligible compensation contributed, for up to $2,500 per year. Pre-tax contributions are allocated to the participant’s individual account and are then invested in selected investment alternatives according to the participant’s directions. The 401(k) plan is intended to qualify under Internal Revenue Code Section 401(a) with the plan’s related trust intended to be tax exempt under Internal Revenue Code Section 501(a). As a tax-qualified retirement plan, the 401(k) plan allows contributions, and earnings on those contributions, not to be taxable to the employees until distributed from the 401(k) plan.

|(4) | The number of shares subject to the PSUs shown in the table represents the total remaining number of unvested shares underlying the award. The number of shares subject to the award that became eligible to vest was determined based on the extent of achievement of the Company’s fiscal year 2016 revenue as previously determined shortly after the Company’s fiscal year ended December 31, 2016. Based on such determination, 80.003% of the total shares subject to this award became eligible to vest and one quarter (1/4) of such vesting-eligible shares is scheduled to vest on each of the one, two, three, and four year anniversaries of the award’s grant date, subject to continued service with us through the applicable vesting date.

|(8) | The number of shares subject to the PSUs shown in the table represents the total number of unvested shares underlying the award. The number of shares subject to the award that may become eligible to vest will determined based on the extent of achievement of the Company’s revenue and cumulative Non-GAAP Operating Margin for the period of October 22, 2018 through December 31, 2020. If a determination is made that the achievement has been met, then on the 5th day of the second month following the achievement quarter, 75% of the Shares subject to the PSU will vest and on the first anniversary of the initial vesting date, the remainder of the shares subject to the PSU will vest, subject to continued service with us through the applicable vesting date. In the event of a Change in Control prior to December 31, 2020, if the performance metric has not been achieved by the date of the Change in Control, the PSU will be treated as though it was a time-based RSU that vested in four equal annual installments with the first vesting date occurring on April 26, 2019 and the other installments vesting on April 26 of the subsequent three years.

Director Compensation


Equity Compensation





Each non-employee director will be granted an initial equity award with a value of $225,000 and an annual equity award with a value of $150,000, which will be granted on the date of our annual stockholder meetings. However, a continuing non-employee director who, as of the date of our annual stockholder meeting, has not served as a board member for the entire 12-month period prior to the annual stockholder meeting will receive an annual award with a value that is prorated based on the number of months the director served during the prior year. The initial and annual equity awards will be granted in the form of RSUs, and the number of shares to be granted pursuant to such equity awards will be determined by the closing price of a share of our common stock on the New York Stock Exchange on the grant date. However, a non-employee director who is not continuing as a director following an annual stockholder meeting will not receive an annual equity award at such meeting.





The initial equity award will be scheduled to vest in three equal, annual installments from the date the non-employee director joins our board of directors, subject to continued service with us through each such date. Each annual award will vest as to 100% of the underlying shares on the earlier of the one year anniversary of the award’s grant date or the date of our next annual stockholder meeting, subject to continued service with us through such date.


Cash Compensation





Our board of directors approved the following annual compensation package for our non-employee directors:

We have determined beneficial ownership in accordance with the rules of the SEC, and thus it represents sole or shared voting or investment power with respect to our securities. Unless otherwise indicated below, to our knowledge, the persons and entities named in the table have sole voting and sole investment power with respect to all shares that they beneficially owned, subject to community property laws where applicable.





We have based our calculation of the percentage of beneficial ownership on 75,183,478 shares of our common stock outstanding as of March 31, 2019. We have deemed shares of our common stock subject to stock options that are currently exercisable or exercisable within 60 days of March 31, 2019 or issuable pursuant to RSUs which are subject to vesting conditions expected to occur within 60 days of March 31, 2019 to be outstanding and to be beneficially owned by the person holding the stock option or RSU for the purpose of computing the percentage ownership of that person. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person.





Unless otherwise indicated, the address of each beneficial owner listed in the table below is c/o A10 Networks, Inc., 3 West Plumeria Drive, San Jose, California 95134. The information provided in the table is based on our records, information filed with the SEC and information provided to us, except where otherwise noted.

ITEM 13. CERTAIN RELATIONSHIPS, RELATED TRANSACTIONS AND DIRECTOR INDEPENDENCE





We describe below transactions and series of similar transactions, since the beginning of our last fiscal year, to which we were a party or will be a party, in which:





|  |

|• | the amounts involved exceeded or will exceed $120,000; and

|  |                                                                                                                                                                                                                                                                                                    
|- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|• | any of our directors, nominees for director, executive officers or holders of more than 5% of our outstanding capital stock, or any immediate family member of, or person sharing the household with any of these individuals or entities, had or will have a direct or indirect material interest.




Other than as described below, there has not been, nor is there any currently proposed, transactions or series of similar transactions to which we have been or will be a party.


Investors Rights Agreement





We are party to an investors rights agreement which provides, among other things, that certain holders of our common stock have the right to demand that we file a registration statement, or request that the shares of such stock be covered by a registration statement that we are otherwise filing, subject to certain exceptions. Lee Chen, our President and Chief Executive Officer, Robert Cochran, our Executive Vice President, Legal and Corporate Collaborations, and certain entities affiliated with Summit Partners, L.P., which hold more than 5% of our outstanding capital stock and one of whose managing directors, Peter Y. Chung, is a member of our board of directors, are parties to the investors rights agreement.


Employment Arrangements and Indemnification Agreements





We have entered into employment and consulting arrangements with certain of our current executive officers. See “Executive Officer Employment Agreements.”





We have also entered into indemnification agreements with certain current and former directors and officers of ours. The indemnification agreements and our restated certificate of incorporation currently in effect and bylaws in effect upon the completion of this offering require us to indemnify our directors and officers to the fullest extent permitted by Delaware law.


Equity Award Grants to Executive Officers and Directors





We have granted stock options, RSUs and/or PSUs to our executive officers and our non-employee directors. See the sections entitled “Executive Compensation” above.


Other Transactions





Other than as described above under this section titled “Related Party Transactions,” since January 1, 2018, we have not entered into any transactions, nor are there any currently proposed transactions, between us and a related party where the amount involved exceeds, or would exceed, $120,000, and in which any related person had or will have a direct or indirect material interest. We believe the terms of the transactions described above were comparable to terms we could have obtained in arm’s-length dealings with unrelated third parties.


Policies and Procedures for Related Party Transactions





The audit committee of our board of directors has the primary responsibility for reviewing and approving transactions with related parties. Our audit committee charter provides that the audit committee may review and approve in advance any related party transactions.








-16-


---







We have adopted a formal written policy providing that our executive officers, directors, nominees for election as directors, beneficial owners of more than 5% of any class of our common stock, any member of the immediate family of any of the foregoing persons, and any firm, corporation, or other entity in which any of the foregoing persons is employed, is a general partner or principal or in a similar position, or in which such person has a 5% or greater beneficial ownership interest, is not permitted to enter into a related party transaction with us without the consent of our audit committee, subject to the exceptions described below. In approving or rejecting any such proposal, our audit committee is to consider the relevant facts and circumstances available and deemed relevant to our audit committee, including, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances, and the extent of the related party’s interest in the transaction. Our audit committee has determined that certain transactions shall be deemed to be pre-approved by the audit committee, even if the aggregate amount involved will exceed $120,000, including certain employment arrangements of executive officers, director compensation, transactions with another company at which a related party’s only relationship is as a non-executive employee or beneficial owner of less than 5% of that company’s shares, transactions where a related party’s interest arises solely from the ownership of our common stock and all holders of our common stock received the same benefit on a pro rata basis, and transactions available to all employees generally.


Director Independence





Our common stock is listed on the New York Stock Exchange. Under the listing standards of the New York Stock Exchange, independent directors must comprise a majority of a listed company’s board of directors. In addition, the listing standards of the New York Stock Exchange require that, subject to specified exceptions, each member of a listed company’s audit, compensation, and nominating and corporate governance committees be independent. Under the listing standards of the New York Stock Exchange, a director will only qualify as an “independent director” if, in the opinion of that listed company’s board of directors, that director does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.





Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the listing standards of the New York Stock Exchange. In addition, compensation committee members must also satisfy the independence criteria set forth under the listing standards of the New York Stock Exchange.





Our board of directors has undertaken a review of the independence of each director. Based on information provided by each director concerning his background, employment and affiliations, our board of directors has determined that Messrs. Braham, Chung, Henricks and Salsbury do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the listing standards of the New York Stock Exchange. In making these determinations, our board of directors considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director, and the transactions involving them described in the section titled “Related Party Transactions.”
