Mr. Wagoner’s retirement package was one of the unanswered questions when the Treasury formed the General Motors Company from assets of the former G.M. last week. After his ouster, Mr. Wagoner remained on the payroll, earning a salary of $1 a year.

Mr. Wagoner, 56, will also receive a life insurance policy that G.M. has maintained for his benefit since Jan. 1, 1997, or its cash value, now $2.57 million, the firm said in the filing. He worked for G.M. for 32 years.

His original pension included a $68,900 yearly amount and five annual payments of $4.5 million.

A Warning on Old G.M. Stock

Investors in the old General Motors have been warned by the government. But will they listen?

The old G.M. stock, now almost certainly worthless, was a star performer during the bankruptcy proceeding of General Motors, when it traded under the ticker symbol GMGMQ.

From 75 cents a share on May 29, before the company filed for bankruptcy, the shares rose to $1.15 before trading was halted on Friday by alarmed regulators who feared heavy volume in the stock might show that investors believed it was in some way connected to the new General Motors. It is not.
