OREANDA-NEWS. Fitch Ratings has updated its criteria report 'U.S. RMBS Cash Flow Analysis Criteria.' The report updates and replaces the report with the same title dated April 2014. The criteria remain fundamentally unchanged, and there is no impact on the outstanding residential mortgage backed securities (RMBS) transactions currently rated by Fitch.

The criteria report summarizes Fitch's current criteria for analyzing the structure of RMBS transactions. The criteria take into account structural features such as triggers and payment priority, as well as the impact of default and prepayment timing.

The key risk drivers in Fitch's analysis of U.S. RMBS cash flows include:

--The timing of defaults;
--The timing of prepayments;
--Residual exposure to interest rate movements.
