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 .

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 .

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 .
