There was plenty in the complex deal to benefit bankers, lawyers, executives and hedge fund managers. Patriot Coal Corp. was bankrupt, but its mines would be auctioned to pay off mounting debts while financial engineering would generate enough cash to cover the cost of the proceedings. When the plan was filed in U.S. bankruptcy court in Richmond last week, however, one group didn’t come out so well: 208 retired miners, wives and widows in southern Indiana who have no direct connection to Patriot Coal. Millions of dollars earmarked for their health care as they age would effectively be diverted instead to legal fees and other bills from the bankruptcy.
