On October 27, 2006, a three-year $1 billion share repurchase program was approved by our Board of Directors. On December 16, 2008, the provisions of the share repurchase program were modified by our Board of Directors to replace the original three-year term with an indefinite term. We repurchased 0.2 and 0.4 shares of common stock for $10.0 and $20.0 during the three and nine months ended September 30, 2014. We repurchased 3.1 shares of common stock for $85.2 during the nine months ended September 30, 2013, respectively. We did not repurchase any shares of common stock during the three months ended September 30, 2013. To date, under the 2006 Share Repurchase Program, the Company has repurchased 15.7 shares for $649.3.

Separate from the 2006 Share Repurchase Program, the Company repurchased 0.1 shares and 0.1 shares for an aggregate price of $5.5 and $2.8, during the nine months endedSeptember 30, 2014 and 2013, respectively, in settlement of employee tax withholding obligations due upon the vesting of restricted stock units.
