G.M. Reaches a Deal With Bondholder Committee

General Motors said in a regulatory filing on Thursday that it has proposed a new deal to a committee representing many of its largest bondholders, offering an equity stake of as much as 25 percent in the restructured automaker in exchange for not opposing G.M.'s reorganization plan.

The filing also fills out many of the details of that plan, crafted under the eye of the Treasury Department, which would be G.M.'s majority owner once it emerged from bankruptcy protection.
