[1] Pursuant to the share withholding provisions of the Fourth Amended and Restated Revlon, Inc. Stock Plan (the "Stock Plan"), the Company withheld an aggregate of 167,297 and 89,620 shares of Revlon Class A Common Stock during 2018 and 2017 to satisfy certain minimum statutory tax withholding requirements related to the vesting of restricted shares for certain senior executives. These withheld shares were recorded as treasury stock using the cost method, at a weighted-average price per share of $21.42 and $27.67 during 2018 and 2017, 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 $3.6 million and $2.5 million, in 2018 and 2017, respectively. In addition, during 2018, the Company transferred to treasury stock 251,495 unvested restricted shares 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 14, "Stock Compensation Plan," for details regarding restricted stock awards under the Stock Plan.
