Moody's revises DaimlerChrysler outlook to negative

NEW YORK, Aug 1 (Reuters) - Moody's Investors Service on Monday revised the outlook DaimlerChrysler AG's debt ratings to negative from stable, citing tougher price competition in the U.S. car market and weak margins in its Mercedes unit.

Downgrades usually raise a company's borrowing costs.

DaimlerChrysler currently holds an "A3" long-term rating and a "Prime-2" short-term rating from Moody's.
