The equity award adjustments for each applicable year include the addition (or subtraction, as applicable) of the following: (i) the year-end fair value of any equity awards granted in the applicable year that are outstanding and unvested as of the end of the year; (ii) the amount of change as of the end of the applicable year (from the end of the prior fiscal year) in fair value of any awards granted in prior years that are outstanding and unvested as of the end of the applicable year; (iii) for awards that are granted and vest in same applicable year, the fair value as of the vesting date; (iv) for awards granted in prior years that vest in the applicable year, the amount equal to the change as of the vesting date (from the end of the prior fiscal year) in fair value; (v) for awards granted in prior years that are determined to fail to meet the applicable vesting conditions during the applicable year, a deduction for the amount equal to the fair value at the end of the prior fiscal year; and (vi) the dollar value of any dividends or other earnings paid on stock or option awards in the applicable year prior to the vesting date that are not otherwise reflected in the fair value of such award or included in any other component of total compensation for the applicable year. The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant.

Cumulative TSR for the Company is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period based on a deemed fixed investment of $100 at the beginning of such period.

Compensation Actually Paid vs. Total Shareholder Return

Relationship of Compensation Actually Paid to Certain Measures

As described in more detail in the Compensation Discussion and Analysis, the Company’s executive compensation program reflects a variable pay-for-performance philosophy. While the Company utilizes several performance measures to align executive compensation with Company performance, all of those Company measures are not presented in the 2023 Pay Versus Performance Table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s performance measures with compensation that is actually paid (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationships between information presented in the 2023 Pay Versus Performance Table.

We believe the table above shows the alignment between compensation actually paid to the NEOs and the Company’s performance, consistent with our compensation philosophy as described in our Compensation Discussion and Analysis. Specifically, a large portion of the NEOs’ compensation is tied to the value of our stock and, as such, the CEO and non-CEO “compensation actually paid” each year was aligned with our TSR performance and increased when our TSR performance increased, but declined when our TSR performance declined. The charts below show, for the past four years, the relationship of the Company’s TSR relative to its peers as well as the relationship between the CEO and non-CEO “compensation actually paid” and (i) the Company’s TSR and the Company’s Peer Group’s TSR; (ii) the Company’s net income; and (iii) EPS.

Tabular List, Table

Most Important Performance Measures for 2023

As described in greater detail in the Compensation Discussion and Analysis, the Company’s executive compensation program includes linking pay of our NEOs to Company, business unit and individual performance as a key objective. The metrics that the Company uses for both our annual cash incentive awards and for performance units that are part of our long-term incentive compensation awards are selected based on an objective of incentivizing our NEOs to increase the value of our enterprise for our long-term stockholders.

For 2023, the most important financial performance measures used by the Company to link executive compensation actually paid to the NEOs, for the most recently completed fiscal year, to the Company’s performance are as follows:
