[ by Melanie Gretchen ] Former Dewey & LeBoeuf employees hopefully have something else lined up - in terms of money to retire on.  That's because the New York law firm isn't going to offer any support to the employee pension plan.   After filing for bankruptcy last month, the fallen firm agreed last week to officially terminate its employee pensions, stepping aside as the U.S. Pension Benefit Guaranty Corporation took the reigns as trustee. When U.S. District Judge Jesse Furman in Manhattan last week signed a consent order terminating 3 employee pension funds, which was said to be underfunded by $80 million, 1,800 past and present employees of the firms and its descendant firms, lost their pension funds. The order also named PBGC as the funds' trustee, which enables the agency to pursue claims for the funds in Dewey's bankruptcy.  Upon filing for Chapter 11 bankruptcy at the end of last month, this former law firm - one of the largest in the country - listed $193 million in assets against $245. million in liabilities. As the largest unsecured creditor, the PBGC is responsible for resolving the $80 million in liabilities associated with the funds.  In addition, it will pay benefits to Dewey's retirees, including the maximum annual benefit for a 65-year-old retiree of almost $56,000. The case: Pension Benefit Guaranty Corporation v. Dewey & LeBoeuf LLP, U.S. District Court of the Southern District of New York, No 12-cv-03833. For further details, go to [Reuters, 6/15/12].
