|net interest income|$ 9640|$ 8700|
|net interest margin|3.94% ( 3.94 % )|3.92% ( 3.92 % )|
changes in net interest income and margin result from the interaction of the volume and composition of interest-earning assets and related yields , interest-bearing liabilities and related rates paid , and noninterest-bearing sources of funding . see the statistical information ( unaudited ) 2013 average consolidated balance sheet and net interest analysis and analysis of year-to-year changes in net interest income in item 8 of this report and the discussion of purchase accounting accretion of purchased impaired loans in the consolidated balance sheet review in this item 7 for additional information . the increase in net interest income in 2012 compared with 2011 was primarily due to the impact of the rbc bank ( usa ) acquisition , organic loan growth and lower funding costs . purchase accounting accretion remained stable at $ 1.1 billion in both periods . the net interest margin was 3.94% ( 3.94 % ) for 2012 and 3.92% ( 3.92 % ) for 2011 . the increase in the comparison was primarily due to a decrease in the weighted-average rate accrued on total interest- bearing liabilities of 29 basis points , largely offset by a 21 basis point decrease on the yield on total interest-earning assets . the decrease in the rate on interest-bearing liabilities was primarily due to the runoff of maturing retail certificates of deposit and the redemption of additional trust preferred and hybrid capital securities during 2012 , in addition to an increase in fhlb borrowings and commercial paper as lower-cost funding sources . the decrease in the yield on interest-earning assets was primarily due to lower rates on new loan volume and lower yields on new securities in the current low rate environment . with respect to the first quarter of 2013 , we expect net interest income to decline by two to three percent compared to fourth quarter 2012 net interest income of $ 2.4 billion , due to a decrease in purchase accounting accretion of up to $ 50 to $ 60 million , including lower expected cash recoveries . for the full year 2013 , we expect net interest income to decrease compared with 2012 , assuming an expected decline in purchase accounting accretion of approximately $ 400 million , while core net interest income is expected to increase in the year-over-year comparison . we believe our net interest margin will come under pressure in 2013 , due to the expected decline in purchase accounting accretion and assuming that the current low rate environment continues . noninterest income noninterest income totaled $ 5.9 billion for 2012 and $ 5.6 billion for 2011 . the overall increase in the comparison was primarily due to an increase in residential mortgage loan sales revenue driven by higher loan origination volume , gains on sales of visa class b common shares and higher corporate service fees , largely offset by higher provision for residential mortgage repurchase obligations . asset management revenue , including blackrock , totaled $ 1.2 billion in 2012 compared with $ 1.1 billion in 2011 . this increase was primarily due to higher earnings from our blackrock investment . discretionary assets under management increased to $ 112 billion at december 31 , 2012 compared with $ 107 billion at december 31 , 2011 driven by stronger average equity markets , positive net flows and strong sales performance . for 2012 , consumer services fees were $ 1.1 billion compared with $ 1.2 billion in 2011 . the decline reflected the regulatory impact of lower interchange fees on debit card transactions partially offset by customer growth . as further discussed in the retail banking portion of the business segments review section of this item 7 , the dodd-frank limits on interchange rates were effective october 1 , 2011 and had a negative impact on revenue of approximately $ 314 million in 2012 and $ 75 million in 2011 . this impact was partially offset by higher volumes of merchant , customer credit card and debit card transactions and the impact of the rbc bank ( usa ) acquisition . corporate services revenue increased by $ .3 billion , or 30 percent , to $ 1.2 billion in 2012 compared with $ .9 billion in 2011 due to higher commercial mortgage servicing revenue and higher merger and acquisition advisory fees in 2012 . the major components of corporate services revenue are treasury management revenue , corporate finance fees , including revenue from capital markets-related products and services , and commercial mortgage servicing revenue , including commercial mortgage banking activities . see the product revenue portion of this consolidated income statement review for further detail . the pnc financial services group , inc . 2013 form 10-k 39 .
