Moody's upgrades ratings of securities issued in CSFB's fixed-rate RMBS transactions from 2003
New York, December 01, 2006 -- Moody's Investors Service has upgraded the ratings of twenty-five
tranches issued by CSFB Mortgage-Backed Pass-Through Certificates
in 2003. These actions are the result of a systematic review of
all 2003 securitizations of fixed-rate collateral by CSFB Mortgage-Backed
Pass-Through Certificates.
All classes being upgraded have performed well in terms of loss and delinquencies
and have built high levels of credit enhancement as compared to the expected
loss on the collateral.
