Additional 402(v) Disclosure | For the relevant fiscal year, represents the cumulative total shareholder return (TSR) of our company's common stock for the measurement periods ending on December 31 of each of 2023, 2022, 2021 and 2020, respectively. Relationship Between "Compensation Actually Paid" and Financial Performance Measures “Compensation actually paid” (“CAP”), as required under SEC rules, reflects adjusted values to unvested and vested equity awards during the years shown in the table based on year-end stock prices, various accounting valuation assumptions, and projected performance modifiers but does not reflect actual amounts paid out for those awards. CAP generally fluctuates due to stock price achievement and varying levels of projected and actual achievement of performance goals. For a discussion of how our Compensation Committee assessed “pay-for-performance” and how our executive compensation program is designed to link executive compensation with the achievement of our financial and strategic objectives as well as stockholder value creation each year, see “Compensation Discussion and Analysis” in this Proxy Statement and in our 2020, 2021, 2022 and 2023 proxy statements. The graph below outlines the relationship between “Compensation Actually Paid” to our CEO and other NEOs in 2020, 2021, 2022 and 2023 and TSR of both our common stock and of the Dow Jones U.S. Electrical Components & Equipment Index. |  |  |
