(a) The Company's unvested restricted stock awards, which include the right to receive non-forfeitable dividends or dividend equivalents, are considered participating securities. Calculations of EPS under the two-class method exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities. The related participating securities are similarly excluded from the denominator.

(b) For both the three and six months ended June 30, 2012, the dilutive effect of unexercised stock options excludes 8 million options, from the computation of EPS because inclusion of the options would have been anti-dilutive. For the three and six months ended June 30, 2011, the dilutive effect of unexercised stock options excludes 19 million and 20 million options, respectively, from the computation of EPS because inclusion of the options would have been anti-dilutive.
