Represents the portion of net income available to common equity that is allocated to participating securities; participating securities, which are composed of unvested restricted stock and director stock, have non-forfeitable rights to dividends during the vesting period on a basis equivalent to dividends paid to common shareholders. 2
Represents stock options, restricted stock and other securities outstanding but not included in the computation of diluted average shares because their effect was anti-dilutive. 3
Calculation for 2010 reflects the allocation of earnings to participating securities using the two-class method, as this computation was more dilutive than the calculation using the treasury stock method. 314Earnings Per Common Share (Details) (USD $)MillionsThousandsNoRoundingUnKnownfalsetrue
