Standard & Poor's lowered its long-term corporate credit rating on Sweden-based Stena AB to double-'B' from double-'B'-plus. The senior unsecured rating on Stena was also lowered, to double-'B'-minus from double-'B'. At the same time, the ratings were removed from CreditWatch, where they were placed with negative implications on Oct. 31, 2000. The outlook is negative. The downgrade reflects Stena's increased exposure to the difficult Northern European ferry market and a weaker financial profile following completion of the acquisition of Stena Line AB. Stena Line, which is wholly owned by Stena, is one of the world's largest ferry companies, with routes in Northern and Western Europe.
