[1] Pursuant to the share withholding provisions of the Fourth Amended and Restated Revlon, Inc. Stock Plan (as amended, the "Stock Plan"), the Company withheld an aggregate of 92,260 and 167,297 shares of Revlon Class A Common Stock during the years ended December 31, 2019 and 2018, respectively, to satisfy certain minimum statutory tax withholding requirements related to the vesting of restricted shares and restricted stock units for certain senior executives and employees. These withheld shares were recorded as treasury stock using the cost method, at a weighted-average price per share of $17.75 and $21.42 during the years ended December 31, 2019 and 2018, respectively, based on the closing price of Revlon Class A Common Stock as reported on the New York Stock Exchange (the "NYSE") consolidated tape on each respective vesting date, for a total of $1.6 million and $3.6 million during the years ended December 31, 2019 and 2018, respectively. In addition, during 2018, the Company transferred to treasury stock 251,495 unvested restricted shares and shares in respect of restricted stock units that were forfeited upon the departure of certain executives. These shares were recorded as treasury stock using the cost method, at a weighted average price of $26.26 per share, based on the grant date fair values of the forfeited shares, for a total of $6.6 million. See Note 13, "Stock Compensation Plan," for details regarding restricted stock awards under the Stock Plan.
