(1) 
Three and nine months ended September 30, 2012 included $8 million related to Series C preferred stock issued in August 2012. Remaining amounts for 2012 periods, and amounts for three and nine months ended September 30, 2011, related to Series A preferred stock, which was redeemed on October 4, 2012.
(2) 
Represented the portion of net income available to common equity allocated to participating securities; participating securities, 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.
(3) 
Represented common stock options and other equity-based awards outstanding, but not included in the computation of diluted average shares because their effect was anti-dilutive.
(4) 
Calculations reflect allocation of earnings to participating securities using the two-class method, as this computation is more dilutive than the calculation using the treasury stock method.
