Colleges saw significantly lower returns on their endowments in the 2015 fiscal year. The annual NACUBO-Commonfund Study of Endowments found that 812 colleges returned an average of just 2.4 percent after fees, down from 15.5 percent in 2014 and the lowest return since the -0.3 percent reported for 2012. The long-term return was well below the median 7.5 percent most endowments report they need to earn to maintain purchasing power after spending, inflation and investment management costs, the report notes. Yet 78 percent of participating institutions spent more from their endowments this year, with a median increase of “a substantial 8.8 percent, well above inflation.”
