Fitch Introduces First Statistically Valid U.S. Multiborrower CMBS Model 

Fitch Ratings said late Friday that it has introduced the first statistically valid U.S. CMBS multiborrower rating model for evaluating the credit risk of commercial mortgage pools. According to the company, the development of the new model follows an extensive study of over 32,000 CMBS fixed-rate conduit loans originated between 1994 and 2001, totaling $173 billion, and how they performed through the end of last year.
