management 2019s discussion and analysis of financial condition and results of operations (continued) the following table presents average u.s. and non-u.s. short-duration advances for the years ended december 31: years ended december 31.
| (In millions) | 2013 | 2012 | 2011 |
| --------- | --------- | --------- | --------- |
| Average U.S. short-duration advances | $2,356 | $1,972 | $1,994 |
| Average non-U.S. short-duration advances | 1,393 | 1,393 | 1,585 |
| Average total short-duration advances | $3,749 | $3,365 | $3,579 |
although average short-duration advances for the year ended december 31, 2013 increased compared to the year ended december 31, 2012, 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 $11.16 billion for the year ended december 31, 2013 from $7.38 billion for the year ended december 31, 2012. the increased levels were primarily the result of higher levels of cash collateral provided in connection with our participation in principal securities finance transactions. aggregate average interest-bearing deposits increased to $109.25 billion for the year ended december 31, 2013 from $98.39 billion for the year ended december 31, 2012. this increase was mainly due to higher levels of non-u.s. transaction accounts associated with the growth of new and existing business in assets under custody and administration. 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 declined to $3.79 billion for the year ended december 31, 2013 from $4.68 billion for the year ended december 31, 2012, as higher levels of client deposits provided additional liquidity. average long-term debt increased to $8.42 billion for the year ended december 31, 2013 from $7.01 billion for the year ended december 31, 2012. the increase primarily reflected the issuance of $1.0 billion of extendible notes by state street bank in december 2012, the issuance of $1.5 billion of senior and subordinated debt in may 2013, and the issuance of $1.0 billion of senior debt in november 2013. this increase was partly offset by maturities of $1.75 billion of senior debt in the second quarter of 2012. average other interest-bearing liabilities increased to $6.46 billion for the year ended december 31, 2013 from $5.90 billion for the year ended december 31, 2012, primarily the result of higher levels of cash collateral received from clients in connection with our participation in principal securities finance transactions. 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, 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 dictate what effect our reinvestment program will have on future levels of our net interest revenue and net interest margin. .
