Quinlan through April 2 0 , 2020, identified below as “CEO 1”, and Mr. Witter for the remainder of 2020 to present, identified below as “CEO 2”), and on an average basis, our other NEOs (in each case, as determined under SEC rules), our TSR, our peer group TSR consisting of the S&P Super Composite Consumer Finance Sub-Industry Index, our net income, and our Company-Selected Measure, relative TSR against a defined group of peers.

1 | The dollar amounts reported in column (b) are the amounts of total compensation reported for Mr. Quinlan (our CEO until April 20, 2020) for each corresponding year in the “Total” column of the Summary Compensation Table. Refer to the Summary Compensation Table as set forth on page 52 of our proxy statement filed with the SEC on April 22, 2021.
2 | The dollar amounts reported in columns (c), (e), and (g) represent the amount of “compensation actually paid” (otherwise known as CAP), adjusted as follow in the table below, as determined in accordance with SEC rules. None of the equity awards held by our NEOs were forfeited during the preceding three years; therefore, no amounts are reported for forfeited awards. “Compensation actually paid” does not necessarily represent cash and/or equity value transferred to the applicable NEO 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 in the table below. Fair values set forth in the table below 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 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.

| (a) | The dollar amounts reported in the Summary Compensation Table for the applicabl e ye ar.

| (c) | The recalculated value of equity awards for each applicable year includes 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;

|  | 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: $8.91 on December 31, 2019, $12.39 on December 31, 2020, $19.67 on December 31, 2021, and $16.60 on December 31, 2022. The stock prices used to calculate the figures in column (iii) in the above table are based on the closing prices on the vesting dates of the applicable awards.
| • |  | The valuation assumptions and processes used to recalculate fair values did not materially differ from those disclosed at the time of grant.
| (d) | “Compensation actually paid” does not necessarily represent cash and/or equity value transferred to the applicable NEO without restriction, but rather is a value calculated under applicable SEC rules.
3 | The dollar amounts reported in column (d) are the amounts of total compensation reported for Mr. Witter (our CEO from April 20, 2020 to present) for each corresponding year in the “Total” column of the Summary Compensation Table. Refer to the Summary Compensation Table as set forth on page 52 of this proxy statement.

2021 |  | Steven J McGarry, Kerri Palmer, Donna Vieira, Daniel Kennedy
2020 |  | Steven J McGarry, Paul Thome, Donna Vieira, Daniel Kennedy
5 | TSR is determined based on the value of an initial fixed investment of $100. The TSR peer group consists of the S&P Super Composite Consumer Finance Sub Industry Index, which is used for our Stock Performance presentation set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.
6 | Our Company-Selected Measure is Relative TSR consistent with the peer group used in the PSU metric under our annual Long Term Incentive Program. For illustrative purposes, calculations within this column are based on 1-year measurements (as opposed to the 3-year relative TSR performance period regarding the Company’s PSUs). For purposes of relative TSR, the peer group used in the PSU metric under our annual Long-Term Incentive Program consists of: (i) the S&P Super Composite Consumer Finance Sub Industry Index and (ii) the S&P 400 Regional Bank Sub-Industry Ind e x.
