The 6th U.S. Circuit Court of Appeals said a lower court judge erred in finding that the Ohio Public Employees Retirement System (OPERS) did not plausibly allege that disclosure shortfalls by Freddie Mac and officials, including former Chief Executive Richard Syron, caused it to lose money on the company's stock.
A spokesman for Freddie Mac said the McLean, Virginia-based mortgage finance company does not discuss pending litigation. The office of Ohio Attorney General Mike DeWine said it is pleased with the decision.
Freddie Mac and the larger Fannie Mae were seized by the U.S. government in September 2008 after racking up huge losses from mortgage securities.
They have since regained profitability, but remain in a federal conservatorship and send profits to the U.S. Treasury Department.
In its lawsuit, which began in January 2008, OPERS accused Freddie Mac of concealing nearly $227 billion in exposure it had taken on to subprime and other low-quality loans, as well as its ability to manage risk and fight fraud.
The fund said Freddie Mac's stock price plunged 29 percent in one day after the truth became known in November 2007.
OPERS sought class action status on behalf of purchases of Freddie Mac stock from Aug. 1, 2006, to Nov. 20, 2007.
Its case has lasted this long in part because the lower court judge who oversaw it for more than five years recused himself in 2013, and because the 6th Circuit took more than nine months after oral arguments to rule.
The case is Ohio Public Employees Retirement System et al v. Federal Home Loan Mortgage Corp et al, 6th U.S. Circuit Court of Appeals, No. 14-4189.
