BOSTON (Standard&Poor's) Aug. 5, 2011--Standard&Poor's Ratings Services said today that its BB-/Stable/-- corporate credit rating on Mississauga, Ontario-based Valeant Pharmaceuticals International Inc. is unchanged following recent announcements that it will acquire Sanitas Group, Dermik, and Ortho Dermatologics in three separate transactions. This follows our expectation that, on a pro forma basis, any debt incurred to fund these acquisitions, which aggregate approximately $1.3 billion, will keep leverage below the company's stated target of 4x.
