Voluntary Employee Beneficiary Association (VEBA)

General Motors Co. will contribute at least $4 billion in cash and $2 billion in GM common stock to the company's $85.9 billion pension plans, the company announced.

Officials of the UAW Retiree Medical Benefit Trust are turning to a conservative risk profile for the $45 billion VEBA, recognizing it will have no employer contributions to make up any investment losses.
