loans and leases averaged $ 15.91 billion for the year ended 2014 , up from $ 13.78 billion in 2013 .
the increase was mainly related to mutual fund lending and our continued investment in senior secured bank loans .
mutual fund lending and senior secured bank loans averaged approximately $ 9.12 billion and $ 1.40 billion , respectively , for the year ended december 31 , 2014 compared to $ 8.16 billion and $ 170 million for the year ended december 31 , 2013 , respectively .

short-duration advances provide liquidity to clients in support of their investment activities .
although average short-duration advances for the year ended december 31 , 2014 increased compared to the year ended december 31 , 2013 , such average advances remained low relative to historical levels , mainly the result of clients continuing to hold higher levels of liquidity .
average other interest-earning assets increased to $ 15.94 billion for the year ended december 31 , 2014 from $ 11.16 billion for the year ended december 31 , 2013 .
the increased levels were primarily the result of higher levels of cash collateral provided in connection with our enhanced custody business .
aggregate average interest-bearing deposits increased to $ 130.30 billion for the year ended december 31 , 2014 from $ 109.25 billion for year ended 2013 .
the higher levels were primarily the result of increases in both u.s .
and non-u.s .
transaction accounts and time deposits .
future transaction account levels will be influenced by the underlying asset servicing business , as well as market conditions , including the general levels of u.s .
and non-u.s .
interest rates .
average other short-term borrowings increased to $ 4.18 billion for the year ended december 31 , 2014 from $ 3.79 billion for the year ended 2013 .
the increase was the result of a higher level of client demand for our commercial paper .
the decline in rates paid from 1.6% ( 1.6 % ) in 2013 to 0.1% ( 0.1 % ) in 2014 resulted from a reclassification of certain derivative contracts that hedge our interest-rate risk on certain assets and liabilities , which reduced interest revenue and interest expense .
average long-term debt increased to $ 9.31 billion for the year ended december 31 , 2014 from $ 8.42 billion for the year ended december 31 , 2013 .
the increase primarily reflected the issuance of $ 1.5 billion of senior and subordinated debt in may 2013 , $ 1.0 billion of senior debt issued in november 2013 , and $ 1.0 billion of senior debt issued in december 2014 .
this is partially offset by the maturities of $ 500 million of senior debt in may 2014 and $ 250 million of senior debt in march 2014 .
average other interest-bearing liabilities increased to $ 7.35 billion for the year ended december 31 , 2014 from $ 6.46 billion for the year ended december 31 , 2013 , primarily the result of higher levels of cash collateral received from clients in connection with our enhanced custody business .
several factors could affect future levels of our net interest revenue and margin , including the mix of client liabilities ; actions of various central banks ; changes in u.s .
and non-u.s .
interest rates ; changes in the various yield curves around the world ; revised or proposed regulatory capital or liquidity standards , or interpretations of those standards ; the amount of discount accretion generated by the former conduit securities that remain in our investment securities portfolio ; and the yields earned on securities purchased compared to the yields earned on securities sold or matured .
based on market conditions and other factors , we continue to reinvest the majority of the proceeds from pay-downs and maturities of investment securities in highly-rated securities , such as u.s .
treasury and agency securities , municipal securities , federal agency mortgage-backed securities and u.s .
and non-u.s .
mortgage- and asset-backed securities .
the pace at which we continue to reinvest and the types of investment securities purchased will depend on the impact of market conditions and other factors over time .
we expect these factors and the levels of global interest rates to influence what effect our reinvestment program will have on future levels of our net interest revenue and net interest margin. .
