Students here at Yale and on four other campuses have announced a national campaign for disclosure by Farallon, one of the nation's largest hedge funds: The coalition wants information from the San Francisco-based company about its investments so that it can better evaluate whether some of them may be environmentally and ethically questionable. The coalition requested a meeting in an open letter sent Tuesday to Farallon's senior managing member, Thomas F. Steyer, a Yale graduate who founded Farallon in 1986. Neither Mr. Steyer nor other officials at Farallon returned phone calls seeking comment. Mr. Ruben said the impetus for the campaign stemmed from a controversy related to Yale's investments that came to light more than two years ago. Yale unions revealed that the university was a member of a partnership that owned a Colorado ranch, of which Farallon was managing partner. Farallon wanted to pump and sell water from an aquifer below the ranch that is adjacent to a national monument. Check out the website, Unfarallon.Info, to get a sense of the breadth and depth of the morally suspect projects around the globe subsidized by this and other universities. An environmental activist from Oregon will be speaking at Yale in WLH this afternoon at 4:30, followed by a "carnival of investments" headed over the David Swenson's office.
