operating environment .
following a challenging first quarter of 2016 , market conditions continued to improve with higher asset prices resulting in full year appreciation in our client assets in both equity and fixed income assets .
also , our assets under supervision increased during 2016 from net inflows , primarily in fixed income assets , and liquidity products .
the mix of our average assets under supervision shifted slightly compared with 2015 from long- term assets under supervision to liquidity products .
management fees have been impacted by many factors , including inflows to advisory services and outflows from actively-managed mutual funds .
in the future , if asset prices decline , or investors continue the trend of favoring assets that typically generate lower fees or investors withdraw their assets , net revenues in investment management would likely be negatively impacted .
during 2015 , investment management operated in an environment generally characterized by strong client net inflows , which more than offset the declines in equity and fixed income asset prices , which resulted in depreciation in the value of client assets , particularly in the third quarter of 2015 .
the mix of average assets under supervision shifted slightly from long-term assets under supervision to liquidity products compared with 2014 .
2016 versus 2015 .
net revenues in investment management were $ 5.79 billion for 2016 , 7% ( 7 % ) lower than 2015 .
this decrease primarily reflected significantly lower incentive fees compared with a strong 2015 .
in addition , management and other fees were slightly lower , reflecting shifts in the mix of client assets and strategies , partially offset by the impact of higher average assets under supervision .
during the year , total assets under supervision increased $ 127 billion to $ 1.38 trillion .
long-term assets under supervision increased $ 75 billion , including net inflows of $ 42 billion , primarily in fixed income assets , and net market appreciation of $ 33 billion , primarily in equity and fixed income assets .
in addition , liquidity products increased $ 52 billion .
operating expenses were $ 4.65 billion for 2016 , 4% ( 4 % ) lower than 2015 , due to decreased compensation and benefits expenses , reflecting lower net revenues .
pre-tax earnings were $ 1.13 billion in 2016 , 17% ( 17 % ) lower than 2015 .
2015 versus 2014 .
net revenues in investment management were $ 6.21 billion for 2015 , 3% ( 3 % ) higher than 2014 , due to slightly higher management and other fees , primarily reflecting higher average assets under supervision , and higher transaction revenues .
during 2015 , total assets under supervision increased $ 74 billion to $ 1.25 trillion .
long-term assets under supervision increased $ 51 billion , including net inflows of $ 71 billion ( which includes $ 18 billion of asset inflows in connection with our acquisition of pacific global advisors 2019 solutions business ) , and net market depreciation of $ 20 billion , both primarily in fixed income and equity assets .
