Harvard is an easy target for the woes of our economy. Its business school produced George W. Bush, the fellow who's presided over the current economic catastrophe, and Rick Wagoner, the CEO of the largest automobile maker who's led its stock down 95% in the last eight years and now wants $25 billion worth of taxpayer money to keep the millions rolling into his bank account. But Harvard had these folks for just two years, so it's tough to blame the school for the current predicament.

However, with $36.9 billion in assets (as of June 30), Harvard also has the largest endowment of any university. And thanks to its big exposure to very illiquid interests in venture capital (VC) and private equity (PE) firms, Harvard leads a growing list of limited partners (LPs) which are selling stocks and those very illiquid interests in order to come up with the cash needed to fulfill their capital calls to these partnerships.

This requires some explaining. VC firms raise money from limited partners such as wealthy individuals, foundations, pension funds, and endowments. But the LPs don't write checks up front -- instead they hold onto their cash and must write a check when the VC calls and asks for the money when the VC is on the verge of making an investment. The problem for many LPs like Harvard is that much of their stock portfolio is locked up in hedge funds and these illiquid VC and PE interests.
