Pay vs Performance Disclosure |  |  |
Pay vs Performance Disclosure, Table | Pay Versus Performance In accordance with the SEC’s disclosure requirements regarding pay versus performance, or PVP, this section presents the SEC-defined “Compensation Actually Paid,” or CAP. Also required by the SEC, this section compares CAP to various measures used to gauge our performance. CAP is a supplemental measure to be viewed alongside performance measures as an addition to the philosophy and strategy of compensation-setting discussed elsewhere in the overview of the executive compensation program, not in replacement. Pay Versus Performance Table The following table sets forth information concerning the compensation of our named executive officers for each of the fiscal years ended December 31, 2023, 2022 and 2021, and our financial performance for each such fiscal year:
