Amounts represent compensation “actually paid” to our principal executive officer, or PEO, and the average compensation actually paid to our remaining NEOs for the relevant fiscal year, as determined under SEC rules (and described below), which includes the individuals indicated in the table below for each fiscal year:

	Year			PEO			Non-PEO NEOs
	2025			Timothy P. Herbert			Randall A. Ban, Richard J. Buchholz, Bryan K. Phillips, and Carlton W. Weatherby

Compensation actually paid (CAP) to our NEOs represents the “Total” compensation reported in the Summary Compensation Table for the applicable fiscal year, as adjusted as reflected below. The fair values of PSUs and stock options included in the CAP to our PEO and the Average CAP to our non-PEO NEOs are calculated at the required measurement dates, consistent with the approach used to value the awards at the grant date as described in Note 6 of our Annual Report on Form 10-K for the year ended December 31, 2025. Any changes to the PSU fair values from the grant date are based on our updated stock price at the respective measurement dates and updated performance metric projections. Changes to the stock option fair values are based on the updated stock price at the respective measurement dates, in addition to updated expected option term, implied volatility of our stock over the updated expected option term, risk-free rate assumptions, and changes to our non-PEO NEOs.
