| Pay vs Performance Disclosure, Table | Pay Versus Performance Table . In accordance with Item 402(v), below is the tabular disclosure for the Company’s CEOs and the average of our NEOs other than the CEO for the past four fiscal years. (a) (b) (c) (c) (d) (e) (f) (g) (h) (i) Value of Initial Fixed $100 Year Summary (1) Summary Compensation (2) Compensation Average (1) Average (2) Total (3) Peer Group (4) GAAP (5) PSU (6) 2023 $ 6,067,969 $ 10,897,739 $ 5,906,451 $ 8,784,009 $ 2,509,460 $ 2,108,923 $ 69 $ 132 $( 12.7 ) $ 574.3 2022 — $ 12,810,155 — $ 11,219,259 $ 2,823,990 $ 2,582,913 $ 71 $ 131 $( 140.6 ) $ 532.8 2021 — $ 10,529,261 — $ 5,240,661 $ 2,816,541 $ 1,954,970 $ 78 $ 132 $( 68.9 ) $ 471.6 2020 — $ 10,967,230 — $ 7,936,371 $ 2,719,981 $ 2,230,948 $ 88 $ 111 $( 162.6 ) $ 542.0 (1) 2023 CEOs are Mr. Lockwood-Taylor (current) and Mr. Kessler (former); other NEOs are E. Bezerra, J. Dillard (former), S. Andersen, K. Hanson, and R. Janish; 2022 CEO is M. Kessler; other NEOs are E. Bezerra, S. Andersen, J. Dillard, K. Hanson, T. Kingma (former), and R. Silcock (former); 2021 CEO is M. Kessler; other NEOs are R. Silcock, J. Dillard, S. Andersen, T. Kingma, and S. Kochan; 2020 CEO is M. Kessler; other NEOs are R. Silcock, S. Andersen, T. Kingma, R. Sorota. (2) The dollar amounts reported represent CAP, as computed in accordance with SEC rules. For all amounts shown in columns (c), the following methods were used to calculate fair value of awards: option awards fair value was determined using a Black-Scholes option-pricing model; restricted stock units (RSUs) fair value was based on PRGO’s closing stock price on each valuation date, including accrued dividend equivalent units; performance stock units (PSUs) fair value assumes estimated performance results as of the end of each reporting year for financial metrics (return on tangible capital was the performance measure for our 2017 and 2018 PSUs, and adjusted operating income was the performance measure for our 2019, 2020, 2021, 2022, and 2023 PSUs) and a Monte Carlo simulation valuation model for market metrics (which were relative TSR vs. a peer group for the 2018, and vs. the S&P 500 constituents for 2019, 2020, 2021, 2022, and 2023 PSUs) , in accordance with FASB ASC 718. The dollar amounts do not reflect the actual amount of compensation earned by or paid during the applicable year. In accordance with SEC rules, the following adjustments were made to the SCT total compensation to determine the CAP values: Reconciliation of Summary Compensation Table to Compensation Actually Paid for CEO: Fiscal Year Reported Minus Summary Plus Year-End Plus (Minus) Plus Fair Plus (Minus) Minus Fair Equals 2023 $ 6,067,969 $ 4,300,008 $ 4,138,489 $ — $ — $ — $ — $ 5,906,451 2023 $ 10,897,739 $ 10,047,050 $ 5,372,539 $( 230,666 ) $ 2,730,013 $ 665,344 $( 603,910 ) $ 8,784,009 2022 $ 12,810,155 $ 9,750,016 $ 9,282,667 $( 758,252 ) $ — $( 219,914 ) $( 145,380 ) $ 11,219,259 2021 $ 10,529,261 $ 7,749,994 $ 6,504,216 $( 1,836,722 ) $ — $( 1,135,832 ) $( 1,070,268 ) $ 5,240,661 2020 $ 10,967,230 $ 7,749,982 $ 6,287,733 $( 1,597,037 ) $ — $ 28,428 $ — $ 7,936,371 Reconciliation of Summary Compensation Table to Compensation Actually Paid for average other NEOs: Fiscal Year Reported Minus Summary Plus Year-End Plus (Minus) Plus Fair Plus (Minus) Minus Fair Equals 2023 $ 2,509,460 $ 1,411,742 $ 1,053,612 $( 44,700 ) $ — $ 54,504 $( 52,211 ) $ 2,108,923 2022 $ 2,823,990 $ 1,862,495 $ 1,530,044 $( 81,925 ) $ 217,254 $( 25,508 ) $( 18,447 ) $ 2,582,913 2021 $ 2,816,541 $ 1,400,030 $ 1,110,898 $( 329,578 ) $ 76,203 $( 159,566 ) $( 159,498 ) $ 1,954,970 2020 $ 2,719,981 $ 1,550,030 $ 1,257,573 $( 197,822 ) $ — $ 10,852 $( 9,608 ) $ 2,230,948 (a) The grant date fair value of equity awards represents the total of the amounts reported in the “Stock Awards” and “Option Awards” columns in the SCT for the applicable year. (3) TSR assumes an investment of $100 on December 31, 2019 and the reinvestment of any dividends. (4) Reflects peer group total shareholder return indexed to $100 for the S&P 1500 Consumer Staples Index, which is an industry line index reported in the performance graph included in the Company’s 2022 Annual Report on Form 10-K. (5) The dollar amounts reported represent the amount of net income (loss) reflected in the Company’s audited financial statements for the applicable year. Values shown reflect PSU OI for the applicable reporting year. | |||

| Compensation Actually Paid vs. Net Income | Relationship between CAP and GAAP Net Income . The graph below reflects the relationship between the CEO and Average other NEO CAP and our GAAP Net Income. As discussed in more detail in our Compensation Discussion & Analysis, GAAP net income is not used as a metric in our annual or long-term incentive plans due to the variance in non-cash and other charges recorded against Net income. As such, we believe that its relationship to CAP and our performance is less illustrative than other metrics that factor more directly into our executive compensation program, including Adj. OI. | |||
| Compensation Actually Paid vs. Company Selected Measure | Relationship between CAP and PSU OI (our Company-Selected Measure). The graph below reflects the relationship between CEO and Average Other NEO CAP and PSU OI. PSU OI was the most heavily weighted financial performance metric under our 2023 incentive programs. We believe that PSU OI is an important profitability measure because it directly aligns with our stated strategic long-term growth “3/5/7” objectives, and, when combined with the other measures utilized in our incentive plans, supports long-term shareholder value creation. While the CAP amounts for our CEO and other NEOs were somewhat correlated with changes in our PSU OI, other factors influence CAP, such as our stock price at the time of vesting during the year, the timing of new equity grants, as well as our performance versus the other measures in our annual and long-term incentive plans. | |||
| Total Shareholder Return Vs Peer Group | Relationship between CAP and TSR of Company and Peer Group . The graphs below illustrate the relationship between CAP for our CEO and other NEOs with the TSR of the Company and the Peer Group. While the CAP amounts for our CEO and other NEOs were generally aligned with our TSR, other factors influence CAP, such as our stock price at the time of vesting during the year, the timing of new equity grants, as well as our performance versus the other measures in our annual and long-term incentive plans. The graph below also illustrates the relationship between our TSR and the Peer Group TSR. | |||
| Tabular List, Table | Metrics 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 2023 to performance. Each metric below is used for purposes of determining payouts under either our annual incentive program or vesting of our PSUs. Please see the CD&A for a further description of these metrics and how they are used in the Company’s executive compensation program. PSU OI Net Income Absolute TSR Relative TSR | |||
