Earnings Per Share [Abstract]  
EARNINGS PER SHARE EARNINGS PER SHAREBasic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period, increased to include the number of shares of common stock that would have been outstanding had potentially dilutive shares of common stock been issued. The dilutive effect of restricted stock units is reflected in diluted earnings per share by applying the treasury stock method.
There are no adjustments required to be made to net income for purposes of computing basic and diluted earnings per share.

These financial statements are prepared on the basis that, at the date of distribution of Sylvamo common stock by International Paper to its shareholders on October 1, 2021, Sylvamo had 43,949,277 total shares of common stock outstanding. The calculation of earnings per share utilizes the number of shares of common stock outstanding at the date of distribution as the basis for the calculation of the weighted average number of shares of common stock outstanding for periods presented prior to the spinoff because, at that time, Sylvamo did not operate as a separate, stand-alone entity, and no shares or equity-based awards were outstanding prior to the date of distribution.

Basic and diluted earnings per share are calculated as follows:
