GM to announce more restructuring Tuesday

General Motors Corp. Chairman and CEO Rick Wagoner will hold a news conference at 9 a.m. Tuesday at the Renaissance Center to discuss actions the company is taking to align the business to current market conditions. Like Detroit rivals Ford Motor Co. and Chrysler LLC, GM is struggling to with a rapid shift in U.S. consumer demand from profitable pickups and SUVs to cars and crossovers in response to a weak economy and gasoline prices that top $4 a gallon.

The rapid shift has sent GM share prices to their lowest levels in more than a half-century in recent weeks and raised speculation about increased prospects for bankruptcy reorganization. GM has denied that it is considering bankruptcy.
