Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
STOCK COMPENSATION PLANS | STOCK COMPENSATION PLANS Our Board of Directors granted 1.5 million restricted stock units and 0.4 million performance share units during the three months ended March 31, 2019 under our stock compensation plans. We measure the fair value of grants of restricted stock units and performance share units based primarily on the closing market price of a share of our common stock on the date of the grant, modified as appropriate to take into account the features of such grants. The weighted average fair value per share was $20.08 for restricted stock units and $18.00 for performance share units granted during the three months ended March 31, 2019. We recognized stock-based compensation expense of $3 million and $2 million during the three months ended March 31, 2019 and 2018, respectively. At March 31, 2019, unearned compensation cost related to the unvested portion of all stock-based awards was approximately $56 million and is expected to be recognized over the remaining vesting period of the respective grants, through the fourth quarter of 2022.
