NEW YORK (Standard & Poor's) Oct. 25, 2006--Standard & Poor's Ratings Services assigned its 'B' rating to WESCO International Inc.'s proposed $250 million convertible senior unsecured notes 2026. Proceeds from the offering will be used to help finance WESCO's acquisition of Communications Supply Holdings Inc. for $525 million. WESCO International is the parent company of WESCO Distribution Inc., its main operating subsidiary. Standard & Poor's also affirmed its 'BB-' corporate credit rating on the electrical distributor. The outlook is stable. "The speculative-grade ratings on WESCO reflect its somewhat aggressive financial policies, which more than offset the company's satisfactory business-risk profile as a leading distributor of electrical construction products; maintenance, repair, and operating supplies; and integrated supply and outsourcing services," said
