Harvard University is committing more capital to a strategy that backs plaintiffs in commercial disputes, delivering robust uncorrelated returns. The strategy is run by IMF Bentham Ltd., a publicly traded company which last week finished raising $500 million for a fifth litigation fund that will focus outside the U.S. Harvard, the world’s richest university, also committed capital to a $500 million fund that IMF Bentham raised last year to finance plaintiffs in the U.S., according to the company.
