Forbes magazine reports that Harvard lost $439 million selling off its private equity portfolio at the bottom of the market last year.

Harvard never publicly disclosed selling any private equity, which has become a money-sucking disaster zone. In its fiscal year ending June 30, 2009, Harvard reported a 31.6% loss in its private equity portfolio. In addition to the $439 million net realized loss, the endowment recorded a $1.9 billion change in net unrealized losses in its private equity portfolio.

While it is unclear how much of its private equity assets Harvard managed to sell or at what price, it seems to have sold some assets when the market was at its weakest point….

What Forbes doesn’t get into is why Harvard to sell at the bottom: The university was running out of cash.
