In the summer of 2015, Penn State's endowment invested $50 million in Pershing Square Capital, a high-profile hedge fund run by New York City billionaire Bill Ackman.

The endowment, one of the largest held by a university, invested as the fund was coming off years of stellar performance. Two years later, the fund has had a reversal of fortune. The Pershing Square International fund reported a loss of 16.6% in 2015 and a loss of 10.2% last year. The fund gained 1.83% through mid-June of this year.

At those rates, a $50 million investment in 2015 would be worth about $38 million now. That doesn't include annual fees, of about 1.5% of the assets (about $750,000 on the initial amount), paid to the hedge fund.
