Pay vs Performance Disclosure [Table] |  |  |
Pay vs Performance [Table Text Block] | Pay Versus Performance Provided below is the Company’s “pay versus performance” disclosure as required pursuant to Item 402(v) of Regulation S-K promulgated under the Exchange Act. As required by Item 402(v), we have included: •A list of the most important measures that our Compensation and Human Capital Committee used in 2022 to link a measure of pay calculated in accordance with Item 402(v) (referred to as “compensation actually paid,” or “CAP”) to Company performance; •A table that compares the total compensation of our named executive officers (“NEOs”) as presented in the Summary Compensation Table (“SCT”) to CAP and that compares CAP to specified performance measures; and •Graphs that describe: ◦the relationship between our total shareholder return (“TSR”) and the TSR of the Dow Jones U.S. Auto Parts Index (“Peer Group TSR”); and ◦the relationships between CAP and our cumulative TSR, GAAP Net Income, and our Company-selected measure, Adjusted Diluted EPS. This disclosure has been prepared in accordance with Item 402(v) and does not necessarily reflect value actually realized by the named executive officers or how our Compensation and Human Capital Committee evaluates compensation decisions in light of Company or individual performance. In particular, our Compensation and Human Capital Committee has not used CAP as a basis for making compensation decisions, nor does it use GAAP Net Income for purposes of determining incentive compensation. Please refer to our Compensation Discussion and Analysis on pages 25 to 39 for a discussion of our executive compensation program objectives and the ways in which we align executive compensation pay with performance. Performance Measures Used for Linking Pay and Performance The following is a list of performance measures, which in our assessment represent the most important performance measures used by the Company to link compensation actually paid to the NEOs for 2022. Each metric below is used for purposes of determining payouts under either our CIP or vesting of our PSU-2s. Please see the Compensation Discussion and Analysis for a further description of these metrics and how they are used in the Company’s executive compensation program.
Adjusted Diluted EPS
Organic Parts and Services Revenue Growth
Free Cash Flow
Return on Invested Capital
EBITDA Dollars
EBITDA Margin
Adjusted Diluted EPS was selected as the Company-selected measure for the Pay versus Performance table that follows because this performance measure has the strongest alignment with the key attributes of our operating plan and drives the creation of long-term shareholder value. Pay Versus Performance Table Below is the tabular disclosure for the Company’s President and Chief Executive Officer (“CEO”) (our Principal Executive Officer) and the average of our NEOs other than the CEO for 2022, 2021 and 2020.

(1) The amounts reported in this column are the amounts of total compensation reported for our Chief Executive Officer, Dominick Zarcone, each corresponding year in the “Total” column of the Summary Compensation Table. (2) CAP to our CEO is computed in accordance with SEC rules. The dollar amounts do not reflect the actual amount of compensation earned by or paid during the applicable year.
