pre_text: management 2019s discussion and analysis 72 jpmorgan chase & co./2015 annual report consolidated results of operations the following section of the md&a provides a comparative discussion of jpmorgan chase 2019s consolidated results of operations on a reported basis for the three-year period ended december 31 , 2015 .
factors that relate primarily to a single business segment are discussed in more detail within that business segment .
for a discussion of the critical accounting estimates used by the firm that affect the consolidated results of operations , see pages 165 2013169 .
revenue year ended december 31 .
post_text: ( a ) included operating lease income of $ 2.1 billion , $ 1.7 billion and $ 1.5 billion for the years ended december 31 , 2015 , 2014 and 2013 , respectively .
2015 compared with 2014 total net revenue for 2015 was down by 2% ( 2 % ) compared with the prior year , predominantly driven by lower corporate private equity gains , lower cib revenue reflecting the impact of business simplification initiatives , and lower ccb mortgage banking revenue .
these decreases were partially offset by a benefit from a legal settlement in corporate , and higher operating lease income , predominantly in ccb .
investment banking fees increased from the prior year , reflecting higher advisory fees , partially offset by lower equity and debt underwriting fees .
the increase in advisory fees was driven by a greater share of fees for completed transactions as well as growth in industry-wide fee levels .
the decrease in equity underwriting fees resulted from lower industry-wide issuance , and the decrease in debt underwriting fees resulted primarily from lower loan syndication and bond underwriting fees on lower industry- wide fee levels .
for additional information on investment banking fees , see cib segment results on pages 94 201398 and note 7 .
principal transactions revenue decreased from the prior year , reflecting lower private equity gains in corporate driven by lower valuation gains and lower net gains on sales as the firm exits this non-core business .
the decrease was partially offset by higher client-driven market-making revenue , particularly in foreign exchange , interest rate and equity-related products in cib , as well as a gain of approximately $ 160 million on ccb 2019s investment in square , inc .
upon its initial public offering .
for additional information , see cib and corporate segment results on pages 94 201398 and pages 105 2013106 , respectively , and note 7 .
asset management , administration and commissions revenue decreased compared with the prior year , largely as a result of lower fees in cib and lower performance fees in am .
the decrease was partially offset by higher asset management fees as a result of net client inflows into assets under management and the impact of higher average market levels in am and ccb .
for additional information , see the segment discussions of cib and am on pages 94 201398 and pages 102 2013104 , respectively , and note 7 .
mortgage fees and related income decreased compared with the prior year , reflecting lower servicing revenue largely as a result of lower average third-party loans serviced , and lower net production revenue reflecting a lower repurchase benefit .
for further information on mortgage fees and related income , see the segment discussion of ccb on pages 85 201393 and notes 7 and 17 .
for information on lending- and deposit-related fees , see the segment results for ccb on pages 85 201393 , cib on pages 94 201398 , and cb on pages 99 2013101 and note 7 ; securities gains , see the corporate segment discussion on pages 105 2013 106 ; and card income , see ccb segment results on pages 85 201393 .
other income was relatively flat compared with the prior year , reflecting a $ 514 million benefit from a legal settlement in corporate , higher operating lease income as a result of growth in auto operating lease assets in ccb , and the absence of losses related to the exit of non-core portfolios in card .
these increases were offset by the impact of business simplification in cib ; the absence of a benefit recognized in 2014 from a franchise tax settlement ; and losses related to the accelerated amortization of cash flow hedges associated with the exit of certain non- operating deposits .
net interest income was relatively flat compared with the prior year , as lower loan yields , lower investment securities net interest income , and lower trading asset balance and yields were offset by higher average loan balances and lower interest expense on deposits .
the firm 2019s average interest-earning assets were $ 2.1 trillion in 2015 , and the net interest yield on these assets , on a fully taxable- equivalent ( 201cfte 201d ) basis , was 2.14% ( 2.14 % ) , a decrease of 4 basis points from the prior year .
2014 compared with 2013 total net revenue for 2014 was down by 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 .
