Stock Ownership Guidelines

To align our officers’ and directors’ interests with those of our stockholders, the Board in December 2013 instituted Stock Ownership Guidelines (the “Guidelines”).

Under the Guidelines, each executive officer is required to own and hold, as a minimum, that number of shares of the Company’s common stock having a market value of at least a stated multiple of the executive officer’s base salary. The stated multiple for the Chief Executive Officer is 3, for a Senior Vice President or Executive Vice President is 1.5, and for a Vice President is 1. For purposes of the Guidelines, common stock includes shares of common stock no matter how acquired (i.e., vesting of restricted shares or restricted stock units, or shares purchased on the open market), unvested time-based restricted shares or restricted stock units, and unvested performance-based restricted shares or restricted stock units at target levels.

Executive officers have 5 years from becoming an executive officer, whichever occurs later, to comply with the ownership requirements. Each named executive officer meets the current minimum requirements.

Anti-Hedging and Anti-Pledging Policy

The Board adopted in October 2013 a policy that prohibits our executive officers from purchasing any financial instrument or entering into any transaction that is designed to hedge or offset any decrease in the market value of Company equity (including, but not limited to, prepaid variable forward contracts, equity swaps, collars, or exchange funds), or pledging, hypothecating, or otherwise encumbering Company equity as collateral for indebtedness.

Clawback Policy

The Board amended and restated in October 2023 its Recovery of Compensation for Accounting Restatements Policy (the “clawback” policy) with respect to incentive-based compensation. The clawback policy provides that in the event of a restatement of the Company’s financial results, the Compensation Committee is entitled to recover from executive officers any incentive-based compensation that would not otherwise have been awarded to such persons under the as-restated financial statements during the three years preceding the date of the restatement. A copy of our Recovery of Compensation for Accounting Restatements Policy was filed as an Exhibit to the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

Insider Trading Policy

The Board amended and restated in February 2006 its Insider Trading Policy, which is applicable to all directors, officers and employees of the Company. This policy expressly prohibits such persons from trading, either directly or indirectly, in our securities after becoming aware of material nonpublic information related to the Company. The policy also establishes guidelines for blackout periods. Our insider trading policy provides guidance as to what constitutes material information and when information becomes public. Before any of our directors, executive officers or other covered persons identified by our insider trading policy engages in certain transactions involving Company securities, such person must obtain pre-clearance and approval of the transaction from our Chief Legal Officer. Furthermore, such individuals, including the NEOs, are only permitted to trade in the Company's securities during prescribed trading windows. The policy discusses the consequences of an insider trading violation, additional trading restrictions, and certain reporting requirements applicable to directors, officers, and designated key employees. A copy of our Insider Trading Policy was filed as an Exhibit to the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

Does the Company have Severance or Change in Control Agreements with its named executive officers?

The named executive officers have severance agreements, which provide for certain benefits upon an involuntary termination. These agreements promote retention of high-performing individuals and also assist in recruiting and retaining key employees by providing competitive arrangements. In addition, the Company has entered into change in control agreements with the named executive officers to provide certain cash payments to the officers upon a termination following a change in control, which is in the form of a “double trigger.” In addition, such agreements provide for an acceleration of equity grants upon a change in control. Change in control agreements are designed to protect executives in the event of a change in control and provide security for executives against sudden or arbitrary termination in connection with a change in control. The provisions of each agreement were determined by analysis of peer group and market trends and practices and are set at competitive levels with industry practice.

For a discussion of these arrangements, including the estimated quantification of these amounts, see the Retention, Severance and Change in Control Agreements discussion following this Compensation Discussion and Analysis.

How do our decisions regarding each element affect decisions regarding the other elements?

The Compensation Committee considers total cash and equity compensation when setting the compensation of executive officers. In doing so, the Compensation Committee considers the retention value of the long-term equity currently held by the executive. Based on this review, the Compensation Committee may decide to adjust one or more elements of an executive’s total compensation. The Compensation Committee aims to provide competitive total direct compensation and assesses an executive’s total compensation package when looking at the executive’s competitive standing relative to the market. Additionally, the Compensation Committee seeks to provide a competitive compensation mix, with discretion depending on factors deemed relevant to the Compensation Committee, such as individual performance, internal equity, and historical pay practices. Certain compensation decisions may specifically affect other elements of compensation. For example, because potential annual cash incentive and long-term equity incentive payouts are based on the executive’s base salary, increases in base salary also increase the amount of such payouts.

What are the tax and accounting considerations that factor into decisions regarding executive compensation?

We consider tax and accounting implications in determining our compensation programs.

Policy on Deductibility of Named Executive Officer Compensation. Section 162(m) of the Internal Revenue Code of 1986, as amended, precludes the tax deductibility of a named executive officer’s compensation that exceeds $1,000,000 per year. The Tax Cuts and Jobs Act, which became effective as of January 1, 2018, modified Section 162(m) provisions, including the elimination of the “performance-based exception” that previously allowed certain performance-based compensation meeting specific requirements to qualify for full tax deductibility by the Company. As a result of the tax law changes, compensation paid to designated “covered executives”, including current and former named executive officers, in excess of $1,000,000 per individual will generally not be deductible, whether or not it is performance-based. Although the Compensation Committee has historically attempted to structure executive compensation to preserve deductibility, it also reserves the right to provide compensation that may not be fully deductible in order to maintain flexibility in compensating named executive officers in a manner consistent with our compensation philosophy, as deemed appropriate. The Compensation Committee believes that stockholder interests are best served by not restricting the Committee’s discretion in this regard, even though such compensation may result in non-deductible compensation expenses to the Company.

Internal Revenue Code Section 409A. The Company reviews its compensation plans and programs for compliance with Section 409A of the Internal Revenue Code and the relevant Treasury Resolutions regarding nonqualified deferred compensation.

Impact of FASB ASC Topic 718. The accounting standards applicable to the various forms of long-term incentive plans under Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 718 is one factor that the Company considers in the design of its long-term equity incentive programs. The Company monitors its FASB ASC Topic 718 expense to ensure that it is reasonable, but expense will not be the most important factor in making decisions about our long-term incentive plans.
