(1)	Senior preferred stock and preferred stock dividends represent pre-tax earnings required to cover any senior preferred stock and preferred stock dividend requirements computed using our effective tax rate, whenever there is an income tax provision, for the relevant periods.
(2)	Ratio of earnings to fixed charges is computed by dividing earnings (loss), as adjusted by total fixed charges. For the ratio to equal 1.00, earnings (loss), as adjusted must increase by $5.7 billion, $14.9 billion, $18.2 billion, $44.1 billion, and $5.5 billion for the years ended December 31, 2011, 2010, 2009, 2008, and 2007, respectively.
(3)	Ratio of earnings to combined fixed charges and preferred stock dividends is computed by dividing earnings (loss), as adjusted by total fixed charges including preferred stock dividends. For the ratio to equal 1.00, earnings (loss), as adjusted must increase by $1.2 billion, $1.0 billion, $12.2 billion, $20.6 billion, $22.3 billion, $44.8 billion, and $5.9 billion for the three months ended March 31, 2012 and 2011 and for the years ended December 31, 2011, 2010, 2009, 2008, and 2007, respectively.
