It goes something like this: We warned you. In a court filing seeking to dismiss the pension fundâs lawsuit against it, Amaranth said Thursday that the fundâs officers âknew exactly what they were getting intoâ when they invested in the now-defunct fund. What the county got into, however, turned out to be a sea of red ink after Amaranth lost about $6.6 billion in the course of a few days last fall. After its energy trades went bad, the fund was forced to shut down in what was the largest-ever collapse of a hedge fund. Amaranthâs collapse prompted some lawmakers to call for greater oversight of hedge funds, which are lightly regulated investment pools usually restricted to institutional and wealthy investors. Some in Congress have said they are especially leery of public employeesâ pension-fund assets being invested in hedge funds. Now, the San Diego County Employees Retirement Association is seeking damages of $150 million based on its $175 million worth of investments with Amaranth. In its lawsuit filed in United States District Court in Manhattan, the pension fund accuses Amaranth of failing to adequately disclose risks and that it made âexcessively risky and volatile investments.â Amaranth answered some of those claims Thursday in a 49-page motion filed by lawyers at Winston & Strawn. (The Wall Street Journalâs Law Blog notes that Nicholas Maounis, who founded Amaranth, has hired star litigator David Boies to represent him personally in the matter.) The fund, which was based in Greenwich, Conn., said it spelled out the risks to potential investors in âpainstaking detailâ in warnings that were repeated âover and over again,â sometimes in bold or all capital letters. It said the pension fundâs officers âwere consciously investing in speculative and leveraged investment strategies involving volatile and illiquid markets without any diversification requirements.â âSimply put,â the motion states, the county âtook a known risk and lost money.â
