Pay vs Performance Disclosure, Table | Pay Versus Performance Table The following table shows for 2023, 2022, 2021 and 2020:
| ● |  | the total compensation disclosed in the Summary Compensation Table (SCT Compensation) for Mr. Kowlzan, our principal executive officer (the PEO) for each of those years;
| ● |  | the average SCT Compensation for Mr. Hassfurther, Mr. Mundy, Mr. Carter and Mr. Shirley, who were our other named executive officers (the Non-PEO NEOs) for each of those years;
| ● |  | the Compensation Actually Paid (CAP), as determined in accordance with Item 402(v) of Regulation S-K under the Securities Exchange Act of 1934, for Mr. Kowlzan for each of those years;
| ● |  | the average CAP for the Other NEOs for each of those years;
| ● |  | the value of an initial fixed $100 investment made on January 1, 2020 as of the end of each of those years in: (a) the Company; and (b) the comparative peer group (the “Comparative Peer Group”) described under “—Long Term Equity Awards” elsewhere in this section (which is the peer group we measure performance against on a relative basis for purposes of determining payouts under our performance units and which is unchanged from the peer group we used in last year’s PVP table) on a weighted-average market capitalization basis;
| ● |  | our net income for each of those years, as reported in accordance with generally accepted accounting principles; and
| ● |  | our earnings per share, excluding special items 3 , for each of those years, which we believe is the most important financial performance measure to us, other than TSR to link compensation actually paid to our performance.

Outstanding and unvested stock awards included in CAP are valued as of the end of the year presented using methodology consistent with the valuation of such awards on the grant date and described in Note 1 to the Summary Compensation Table included in this proxy statement. Restricted stock is valued at the closing market price on the New York Stock Exchange on the last trading day of the year presented. The valuation of ROIC Units is determined based upon the probable outcome, which, for all outstanding units for all periods, was payout at 100%. The valuation of the TSR Units was redetermined as of the end of each year based upon a Monte Carlo simulation. In each case, “Dividends” include dividends paid in cash on unvested restricted stock awards and the year over year change in value of accrued dividends on ROIC Performance Units. |  |  |
