Question:
by how much more is the net gains from sales of available-for-sale securities in 2009 compare to 2008?


pre_text: note 12 .
shareholders 2019 equity accumulated other comprehensive loss : accumulated other comprehensive loss included the following components as of december 31: .
post_text: the net after-tax unrealized loss on available-for-sale securities of $ 1.64 billion and $ 5.21 billion as of december 31 , 2009 and december 31 , 2008 , respectively , included $ 635 million and $ 1.39 billion , respectively , of net after-tax unrealized losses related to securities reclassified from securities available for sale to securities held to maturity .
the decrease in the losses related to transfers compared to december 31 , 2008 resulted from amortization and from the recognition of losses from other-than-temporary impairment on certain of the securities .
additional information is provided in note 3 .
for the year ended december 31 , 2009 , we realized net gains of $ 368 million from sales of available-for-sale securities .
unrealized pre-tax gains of $ 46 million were included in other comprehensive income at december 31 , 2008 , net of deferred taxes of $ 18 million , related to these sales .
for the year ended december 31 , 2008 , we realized net gains of $ 68 million from sales of available-for-sale securities .
unrealized pre-tax gains of $ 71 million were included in other comprehensive income at december 31 , 2007 , net of deferred taxes of $ 28 million , related to these sales .
for the year ended december 31 , 2007 , we realized net gains of $ 7 million on sales of available-for-sale securities .
unrealized pre-tax losses of $ 32 million were included in other comprehensive income at december 31 , 2006 , net of deferred taxes of $ 13 million , related to these sales .
preferred stock : in october 2008 , in connection with the u.s .
treasury 2019s capital purchase program , we issued 20000 shares of our series b fixed-rate cumulative perpetual preferred stock , $ 100000 liquidation preference per share , and a warrant to purchase 5576208 shares of our common stock at an exercise price of $ 53.80 per share , to treasury , and received aggregate proceeds of $ 2 billion .
the aggregate proceeds were allocated to the preferred stock and the warrant based on their relative fair values on the date of issuance .
as a result , approximately $ 1.88 billion and $ 121 million , respectively , were allocated to the preferred stock and the warrant .
the difference between the initial value of $ 1.88 billion allocated to the preferred stock and the liquidation amount of $ 2 billion was intended to be charged to retained earnings and credited to the preferred stock over the period that the preferred stock was outstanding , using the effective yield method .
for 2008 and 2009 , these charges to retained earnings reduced net income available to common shareholders by $ 4 million and $ 11 million , respectively , and reduced basic and diluted earnings per common share for those periods .
these calculations are presented in note 22 .
the preferred shares qualified as tier 1 regulatory capital , and paid cumulative quarterly dividends at a rate of 5% ( 5 % ) per year .
for 2008 and 2009 , the accrual of dividends on the preferred shares reduced net income available to common shareholders by $ 18 million and $ 46 million , respectively , and reduced basic and diluted earnings per common share for those periods .
these calculations are presented in note 22 .
the warrant was immediately .
