Pay vs Performance [Table Text Block] | Pay Versus Performance Our Committee designed an executive compensation program to link a majority of our NEOs’ realized compensation to achievement of Sylvamo’s financial, commercial and strategic goals, and to align executives’ interest with those of shareowners. The table below shows the total compensation for our NEOs for the past two years, the “compensation actually paid ” to our CEO and, on an average basis, our other NEOs, our TSR, the TSR of the S&P Small Cap Materials Index, our net income and our financial performance measure for compensatory purposes, Free Cash Flow.

(1) On October 1, 2021, the Company spun off from International Paper and became a publicly traded company, as such we are reporting fiscal 2022 and the period October 1, 2021 through December 31, 2021. (2) The amounts shown in this column represent the total compensation, per the Summary Compensation Table, (see page 46), for our CEO, Mr. Ribiéras, for the period October 1, 2021 through December 31, 2021 and fiscal year 2022. (3) SEC rules require certain adjustments be made to the Summary Compensation Table totals to determine “compensation actually paid” as reported above. The amounts shown do not necessarily reflect the actual amounts of compensation paid to our CEO or other NEOs during the applicable year as they include (i) the year-end value of equity awards granted during the reported year that have not yet vested, (ii) the change in the value of equity awards that were unvested at the end of the prior year, measured through the date the awards vested or were forfeited, or through the end of the fiscal year and (iii) certain pension related costs. Below is a calculation of “compensation actually paid” to the CEO and other NEOs (“Other NEOs”), which for 2022 are Messrs. Sims, Gibson, Barron and Wilczynski and for 2021 Messrs.
