Moody's Investors Service downgraded the ratings of American Commercial Lines LLC's $535 million senior secured bank facility to B1 from Ba2 and the $300 million 10.25% senior unsecured notes to B3 from B1. The Senior Implied rating was lowered to B2 from Ba3 and the issuer rating was lowered to Caa1 from B2. The rating outlook was changed to stable from negative. The ratings downgrades is prompted by the substantial deterioration in operating performance resulting from a reduction in grain exports to Asia, higher fuel costs, and low water levels and unusual ice conditions on its U.S. transport routes which severely impacted the fourth quarter of 2000.
