what percent of total net revenue was noninterest revenue in 2009?
2009 compared with 2008 total net revenue was $ 100.4 billion , up by $ 33.2 billion , or 49% ( 49 % ) , from the prior year . the increase was driven by higher principal transactions revenue , primarily related to improved performance across most fixed income and equity products , and the absence of net markdowns on legacy leveraged lending and mortgage positions in ib , as well as higher levels of trading gains and investment securities income in corporate/private equity . results also benefited from the impact of the washington mutual transaction , which contributed to increases in net interest income , lending- and deposit-related fees , and mortgage fees and related income . lastly , higher investment banking fees also contributed to revenue growth . these increases in revenue were offset partially by reduced fees and commissions from the effect of lower market levels on assets under management and custody , and the absence of proceeds from the sale of visa shares in its initial public offering in the first quarter of 2008 . investment banking fees increased from the prior year , due to higher equity and debt underwriting fees . for a further discussion of invest- ment banking fees , which are primarily recorded in ib , see ib segment results on pages 63 201365 of this annual report . principal transactions revenue , which consists of revenue from trading and private equity investing activities , was significantly higher com- pared with the prior year . trading revenue increased , driven by improved performance across most fixed income and equity products ; modest net gains on legacy leveraged lending and mortgage-related positions , compared with net markdowns of $ 10.6 billion in the prior year ; and gains on trading positions in corporate/private equity , compared with losses in the prior year of $ 1.1 billion on markdowns of federal national mortgage association ( 201cfannie mae 201d ) and fed- eral home loan mortgage corporation ( 201cfreddie mac 201d ) preferred securities . these increases in revenue were offset partially by an aggregate loss of $ 2.3 billion from the tightening of the firm 2019s credit spread on certain structured liabilities and derivatives , compared with gains of $ 2.0 billion in the prior year from widening spreads on these liabilities and derivatives . the firm 2019s private equity investments pro- duced a slight net loss in 2009 , a significant improvement from a larger net loss in 2008 . for a further discussion of principal transac- tions revenue , see ib and corporate/private equity segment results on pages 63 201365 and 82 201383 , respectively , and note 3 on pages 156 2013 173 of this annual report . lending- and deposit-related fees rose from the prior year , predomi- nantly reflecting the impact of the washington mutual transaction and organic growth in both lending- and deposit-related fees in rfs , cb , ib and tss . for a further discussion of lending- and deposit- related fees , which are mostly recorded in rfs , tss and cb , see the rfs segment results on pages 66 201371 , the tss segment results on pages 77 201378 , and the cb segment results on pages 75 201376 of this annual report . the decline in asset management , administration and commissions revenue compared with the prior year was largely due to lower asset management fees in am from the effect of lower market levels . also contributing to the decrease were lower administration fees in tss , driven by the effect of market depreciation on certain custody assets and lower securities lending balances ; and lower brokerage commis- sions revenue in ib , predominantly related to lower transaction vol- ume . for additional information on these fees and commissions , see the segment discussions for tss on pages 77 201378 , and am on pages 79 201381 of this annual report . securities gains were lower in 2009 and included credit losses related to other-than-temporary impairment and lower gains on the sale of mastercard shares of $ 241 million in 2009 , compared with $ 668 million in 2008 . these decreases were offset partially by higher gains from repositioning the corporate investment securities portfolio in connection with managing the firm 2019s structural interest rate risk . for a further discussion of securities gains , which are mostly recorded in corporate/private equity , see the corpo- rate/private equity segment discussion on pages 82 201383 of this annual report . mortgage fees and related income increased slightly from the prior year , as higher net mortgage servicing revenue was largely offset by lower production revenue . the increase in net mortgage servicing revenue was driven by growth in average third-party loans serviced as a result of the washington mutual transaction . mortgage production revenue declined from the prior year , reflecting an increase in esti- mated losses from the repurchase of previously-sold loans , offset partially by wider margins on new originations . for a discussion of mortgage fees and related income , which is recorded primarily in rfs 2019s consumer lending business , see the consumer lending discus- sion on pages 68 201371 of this annual report . credit card income , which includes the impact of the washington mutual transaction , decreased slightly compared with the prior year .
