1 . includes net revenues related to reinsurance of $ 1.08 billion , $ 880 million and $ 827 million for the years ended december 2012 , december 2011 and december 2010 , respectively . 2012 versus 2011 . net revenues in institutional client services were $ 18.12 billion for 2012 , 5% ( 5 % ) higher than 2011 . net revenues in fixed income , currency and commodities client execution were $ 9.91 billion for 2012 , 10% ( 10 % ) higher than 2011 . these results reflected strong net revenues in mortgages , which were significantly higher compared with 2011 . in addition , net revenues in credit products and interest rate products were solid and higher compared with 2011 . these increases were partially offset by significantly lower net revenues in commodities and slightly lower net revenues in currencies . although broad market concerns persisted during 2012 , fixed income , currency and commodities client execution operated in a generally improved environment characterized by tighter credit spreads and less challenging market-making conditions compared with 2011 . net revenues in equities were $ 8.21 billion for 2012 , essentially unchanged compared with 2011 . net revenues in securities services were significantly higher compared with 2011 , reflecting a gain of approximately $ 500 million on the sale of our hedge fund administration business . in addition , equities client execution net revenues were higher than 2011 , primarily reflecting significantly higher results in cash products , principally due to increased levels of client activity . these increases were offset by lower commissions and fees , reflecting lower market volumes . during 2012 , equities operated in an environment generally characterized by an increase in global equity prices and lower volatility levels . the net loss attributable to the impact of changes in our own credit spreads on borrowings for which the fair value option was elected was $ 714 million ( $ 433 million and $ 281 million related to fixed income , currency and commodities client execution and equities client execution , respectively ) for 2012 , compared with a net gain of $ 596 million ( $ 399 million and $ 197 million related to fixed income , currency and commodities client execution and equities client execution , respectively ) for 2011 . during 2012 , institutional client services operated in an environment generally characterized by continued broad market concerns and uncertainties , although positive developments helped to improve market conditions . these developments included certain central bank actions to ease monetary policy and address funding risks for european financial institutions . in addition , the u.s . economy posted stable to improving economic data , including favorable developments in unemployment and housing . these improvements resulted in tighter credit spreads , higher global equity prices and lower levels of volatility . however , concerns about the outlook for the global economy and continued political uncertainty , particularly the political debate in the united states surrounding the fiscal cliff , generally resulted in client risk aversion and lower activity levels . also , uncertainty over financial regulatory reform persisted . if these concerns and uncertainties continue over the long term , net revenues in fixed income , currency and commodities client execution and equities would likely be negatively impacted . operating expenses were $ 12.48 billion for 2012 , 3% ( 3 % ) lower than 2011 , primarily due to lower brokerage , clearing , exchange and distribution fees , and lower impairment charges , partially offset by higher net provisions for litigation and regulatory proceedings . pre-tax earnings were $ 5.64 billion in 2012 , 27% ( 27 % ) higher than 2011 . 2011 versus 2010 . net revenues in institutional client services were $ 17.28 billion for 2011 , 21% ( 21 % ) lower than 2010 . net revenues in fixed income , currency and commodities client execution were $ 9.02 billion for 2011 , 34% ( 34 % ) lower than 2010 . although activity levels during 2011 were generally consistent with 2010 levels , and results were solid during the first quarter of 2011 , the environment during the remainder of 2011 was characterized by broad market concerns and uncertainty , resulting in volatile markets and significantly wider credit spreads , which contributed to difficult market-making conditions and led to reductions in risk by us and our clients . as a result of these conditions , net revenues across the franchise were lower , including significant declines in mortgages and credit products , compared with 2010 . 54 goldman sachs 2012 annual report .
