Equity [Abstract] |
CAPITAL STOCK | CAPITAL STOCK On October 27, 2006, a three-year $1 billion share repurchase program was approved by the Board of Directors (the Share Repurchase Program). On December 16, 2008, the provisions of the Share Repurchase Program were modified by the Board of Directors to replace the original three-year term with an indefinite term. During the six months ended June 30, 2018 and 2017, we repurchased and retired 1.0 and 0.8 shares of common stock for $50.0 and $30.0, respectively, under this program. To date, the Company has repurchased 22.1 shares for $909.4 under the Share Repurchase Program. Separate from the Share Repurchase Program, the Company repurchased 0.1 shares during both the six months ended June 30, 2018 and 2017, respectively, for an aggregate price of $5.4 and $2.8, respectively, in settlement of employee tax withholding obligations due upon the vesting of RSUs and PSUs.
