revenue year ended december 31 .
post_text: ( a ) included funding valuation adjustments ( ( 201cfva 201d ) effective 2013 ) ) and debit valuation adjustments ( 201cdva 201d ) on over-the-counter ( 201cotc 201d ) derivatives and structured notes , measured at fair value .
fva and dva gains/ ( losses ) were $ 468 million and $ ( 1.9 ) billion for the years ended december 31 , 2014 and 2013 , respectively .
dva losses were ( $ 930 ) million for the year ended december 31 , 2012 .
( b ) included operating lease income of $ 1.7 billion , $ 1.5 billion and $ 1.3 billion for the years ended december 31 , 2014 , 2013 and 2012 , respectively .
2014 compared with 2013 total net revenue for 2014 was down by $ 2.4 billion , or 2% ( 2 % ) , compared with the prior year , predominantly due to lower mortgage fees and related income , and lower other income .
the decrease was partially offset by higher asset management , administration and commissions revenue .
investment banking fees increased compared with the prior year , due to higher advisory and equity underwriting fees , largely offset by lower debt underwriting fees .
the increase in advisory fees was driven by the combined impact of a greater share of fees for completed transactions , and growth in industry-wide fee levels .
the increase in equity underwriting fees was driven by higher industry-wide issuance .
the decrease in debt underwriting fees was primarily related to lower bond underwriting compared with a stronger prior year , and lower loan syndication fees on lower industry-wide fee levels .
investment banking fee share and industry-wide data are sourced from dealogic , an external vendor .
for additional information on investment banking fees , see cib segment results on pages 92 201396 , cb segment results on pages 97 201399 , and note 7 .
principal transactions revenue , which consists of revenue primarily from the firm 2019s client-driven market-making and private equity investing activities , increased compared with the prior year as the prior year included a $ 1.5 billion loss related to the implementation of the fva framework for otc derivatives and structured notes .
the increase was also due to higher private equity gains as a result of higher net gains on sales .
the increase was partially offset by lower fixed income markets revenue in cib , primarily driven by credit- related and rates products , as well as the impact of business simplification initiatives .
for additional information on principal transactions revenue , see cib and corporate segment results on pages 92 201396 and pages 103 2013104 , respectively , and note 7 .
lending- and deposit-related fees decreased compared with the prior year , reflecting the impact of business simplification initiatives and lower trade finance revenue in cib .
for additional information on lending- and deposit- related fees , see the segment results for ccb on pages 81 2013 91 , cib on pages 92 201396 and cb on pages 97 201399 .
asset management , administration and commissions revenue increased compared with the prior year , reflecting higher asset management fees driven by net client inflows and the effect of higher market levels in am and ccb .
the increase was offset partially by lower commissions and other fee revenue in ccb as a result of the exit of a non-core product in the second half of 2013 .
for additional information on these fees and commissions , see the segment discussions of ccb on pages 81 201391 , am on pages 100 2013102 , and note 7 .
securities gains decreased compared with the prior year , reflecting lower repositioning activity related to the firm 2019s investment securities portfolio .
for additional information , see the corporate segment discussion on pages 103 2013104 and note 12 .
mortgage fees and related income decreased compared with the prior year .
the decrease was predominantly due to lower net production revenue driven by lower volumes due to higher levels of mortgage interest rates , and tighter margins .
the decline in net production revenue was partially offset by a lower loss on the risk management of mortgage servicing rights ( 201cmsrs 201d ) .
for additional information , see the segment discussion of ccb on pages 85 201387 and note 17 .
card income remained relatively flat but included higher net interchange income on credit and debit cards due to growth in sales volume , offset by higher amortization of new account origination costs .
for additional information on credit card income , see ccb segment results on pages 81 201391. .
