A Washington federal trial judge today approved a $153 million settlement between Fannie Mae and shareholders who sued the mortgage giant for securities fraud.

U.S. District Judge Richard Leon found the settlement and plan for distributing it among the more than one million class members was “fair, reasonable and adequate.” The case is the largest securities class action settlement in the D.C. federal courts since modern securities litigation laws went into effect in 1996.

The order ends nearly a decade of litigation against Fannie Mae and its auditor, KPMG LLP. The class members, led by the Ohio Public Employees Retirement System and the State Teachers Retirement System of Ohio, accused Fannie Mae and KPMG of defrauding shareholders by manipulating earning and violating guidelines known as generally accepted accounting principles.

The plaintiffs suffered a string of losses shortly before reaching the settlement. In 2012, Leon dismissed three former Fannie Mae executives as defendants, finding the plaintiffs failed to present enough evidence they intended to deceive shareholders. Other motions for summary judgment filed by Fannie Mae and KPMG were pending when the parties announced the settlement in May.
