OREANDA-NEWS. Fitch Ratings has updated its criteria for analysing securities backed by UK residential mortgage loans.

The assumptions are used for rating new and existing RMBS transactions as well as mortgage covered bond programmes. In addition the market value decline assumptions are applicable to the ratings of SME CLOs secured by residential real estate.

The criteria addendum replaces the report of the same name dated 30 May 2014.

The only changes relate to the removal of adjustments related to right-to-buy and fast track loans.

The update does not have any impact on existing ratings.
