OREANDA-NEWS. Fitch Ratings has affirmed the Douro Mortgages series. A full list of rating actions follows at the end of this ratings action commentary.

The three transactions comprise loans originated and serviced by Banco BPI (BB/Stable/F1).

Robust Performance
The transactions continue to report a limited volume of loans in arrears by three months or more. As of the latest payment date, late-stage arrears range from 0.3% (Douro 2) to 0.5% (Douro 1) of the current portfolio balance, which is well below the 1.0% Portuguese RMBS average for three-month plus arrears.

The transactions feature a provisioning mechanism, whereby excess spread is diverted to principal distributions to cover deemed principal losses. The amount provisioned is dependent on the number of monthly instalments in arrears.

To account for the staggered nature of provisions, Fitch has estimated the volume of loans that have defaulted, but for which full provisions have not yet been made. These amounts make up between 0.2% (Douro 1) to 0.5% (Douro 3) of the current portfolio balance. They have been deducted from the available credit enhancement in Fitch's analysis, as these provisions will only be made in the coming quarters.

Basis Risk
Banco BPI has continued to post collateral in relation to the swap in Douro 1. Due to the recent downgrade of Banco BPI to 'BB'/Stable/'B', Fitch no longer views the posting of collateral as a sufficient mitigant to the exposure to support notes rated in the 'Asf' category. Therefore Fitch has disregarded the effect of the swap and applied a haircut to the excess spread in its analysis to account for the exposure to basis risk.

Deterioration in asset performance may result from economic factors. A corresponding increase in new defaults and associated pressure on excess spread levels and reserve funds beyond Fitch's assumptions could result in negative rating action.

The ratings are also sensitive to changes to Portugal's Country Ceiling (A+) and, consequently, changes to the highest achievable rating of Portuguese structured finance notes.

No third party due diligence was provided or reviewed in relation to this rating action.

Fitch has checked the consistency and plausibility of the information it has received about the performance of the asset pools and the transactions. There were no findings that were material to this analysis. Fitch has not reviewed the results of any third party assessment of the asset portfolio information or conducted a review of origination files as part of its ongoing monitoring.

Fitch did not undertake a review of the information provided about the underlying asset pools ahead of the transactions' initial closing. The subsequent performance of the transactions over the years is consistent with the agency's expectations given the operating environment and Fitch is therefore satisfied that the asset pool information relied upon for its initial rating analysis was adequately reliable.

Overall, Fitch's assessment of the information relied upon for the agency's rating analysis according to its applicable rating methodologies indicates that it is adequately reliable.
