General Motors ( GM) will widen its reported loss for 2005 by roughly $2 billion as a result of adjusting some previously reported charges. The automaking giant said late Thursday that when it files its 10-K its loss for the full year will move to $10.6 billion, or $18.69 a share, from its prior announcement of $8.6 billion, or $15.13 a share. The final 2005 results will include an increase in the previously announced North American restructuring charge to $1.7 billion from $1.3 billion; an increase to the contingent liabilities associated with Delphi's Chapter 11 filing to $3.6 billion from $2.3 billion.; and recognition at the GM level of the previously reported noncash goodwill impairment charge of $439 million (after tax) at GMAC. GM will delay filing its form 10-K but plans to file in the next two weeks. Shares of GM closed Thursday up 72 cents, or 3.4%, to $22.22.
