PEO Actually Paid Compensation Amount | $ 6,319,238 | 1,160,593 | 254,886 |
Adjustment To PEO Compensation, Footnote | The dollar amounts reported in columns (c) and (e) represent the amount of “compensation actually paid” (otherwise known as CAP), reconciled in the table below, as determined in accordance with SEC rules. “Compensation actually paid” does not necessarily represent cash and/or equity value transferred to the applicable named executive officer without restriction, but rather is a value calculated under applicable SEC rules. We do not have a defined benefit plan, so no adjustment for pension benefits is included. Fair values set forth in the table are computed in accordance with ASC 718 as of the end of the respective fiscal year, other than fair values of the awards that vest in the covered year, which are valued as of the applicable vesting date. Similarly, no adjustment is made for dividends because the amount associated with such dividends, if any were paid, are reflected in the fair value of the award for the covered fiscal year. The reconciliation from the Summary Compensation Table to CAP is summarized in the table below.

While the equity awards disclosed in the Summary Compensation Table are based on the grant date fair values computed in accordance with FASB ASC Topic 718, the equity award values disclosed pursuant to CAP in the table above are calculated in the following manner: •The stock prices used to calculate the figures in columns (i) and (ii) in the above table are as follows: $13.22 on December 31, 2020, $11.99 on December 31, 2021, $5.83 on December 31, 2022 and $8.11 on December 31, 2023.
