CAPITAL STOCK

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. To offset the dilution caused by recent exercises of employee stock options we repurchased 1.1 shares of common stock for $24.6 during the three months ended June 30, 2012, resulting in aggregate repurchases of 3.3 shares of common stock for $73.6 for the six months of 2012. No shares were repurchased under the 2006 Share Repurchase Program during either the three or six month periods ending June 30, 2011. To date, under the 2006 Share Repurchase Program, the Company has repurchased 6.8 shares for $504.3, including commissions.

Separate from the 2006 Share Repurchase Program, the Company repurchased 0.1 shares and 0.1 shares for an aggregate price of $3.2 and $5.4, during the six months ended June 30, 2012 and 2011, respectively, in settlement of employee tax withholding obligations due upon the vesting of restricted stock or stock units.
