(b) For fiscal years 2022, 2021 and 2020, Mr. Sutton was the Principle Executive Officer (PEO) for the Company. (c) The Compensation Actually Paid (CAP) was calculated beginning with the PEO’s Summary Compensation Table (SCT) total then deducting the aggregate change in actuarial present value of his accumulated benefit under all defined benefit and actuarial pension plans reported in the SCT; deducting the amounts reported in the SCT for performance share awards; adding the fair value as of the end of the covered fiscal year of all awards granted during the fiscal year that are outstanding and unvested as of the fiscal year-end; adding the amount equal to the change in fair value as of the end of the covered fiscal year, whether positive or negative, of any awards granted in any prior fiscal year that are outstanding and unvested as of the end of the covered fiscal year; adding the amount equal to the change in fair value as of the vesting date, whether positive or negative, of any award granted in any prior fiscal year for which all applicable vesting conditions were satisfied at the end of or during the covered fiscal year. Relative to the PEO’s CAP, the following amounts were deducted from and added to SCT total compensation.

Also, the additions to the SCT Total reflect the value of equity calculated in accordance with the SEC methodology for determining CAP for each year shown. The equity component of CAP for fiscal year 2022 is further detailed in the supplemental table below. The equity awards were revalued using the Sylvamo pre-spin share counts and Monte Carlo values for the relative TSR PSUs, and the post-spin adjusted share prices for the ROIC PSUs.
