The University of Michigan’s $10 billion endowment added to its investments in venture capital, private equity and real estate as it struggles to recover from losses. Michigan invested $177 million in commitments mostly to the private funds, with $45 million going to two energy pools, according to the Board of Regents agenda for its meeting Thursday. The marketable securities portfolio, which makes up 58 percent of the endowment, lost 2.7 percent in the fiscal year through May 31. Many schools say they are expecting negative returns in fiscal 2016 after the slowdown in China and the U.K.’s decision to leave the European Union stirred market turmoil. Michigan’s absolute return portfolio was down 4.1 percent through May 31, and equities, which comprise its largest allocation at 26 percent, fell 5.4 percent.
