OREANDA-NEWS. Fitch Ratings has assigned Hypenn RMBS III B.V.'s mortgage-backed notes expected ratings, as follows:

Class A1 floating-rate notes: 'AAA(EXP)sf'; Outlook Stable
Class A2 floating-rate notes: 'AAA(EXP)sf'; Outlook Stable
Class B fixed-rate notes: not rated

The final ratings are subject to the receipt of final documents conforming to information already received.

The transaction is a true sale securitisation of mortgage loans originated in the Netherlands by Nationale-Nederlanden Bank N.V. (NNB) and Nationale-Nederlanden Levensverzekeringsmaatschappij N.V. (NNL) which were subsequently sold to NNB.

Credit enhancement (CE) for the class A notes will be 7.0% at closing, provided by the subordination of the class B notes.

KEY RATING DRIVERS
Portfolio Composition
The 52-month seasoned static portfolio consists of prime fixed rate residential mortgage loans with a weighted-average (WA) original loan-to-market-value (OLTMV) of 94.4% and a debt-to-income ratio (DTI) of 28.0%. The WA OLTMV is around 6% above the level typically seen in Fitch-rated Dutch RMBS transactions.

NHG Loans
The portfolio comprises 24.6% of loans that benefit from the national mortgage guarantee scheme (Nationale Hypotheek Garantie or NHG). No reduction in foreclosure frequency for the NHG loans was applied, since historical data provided did not show a clear pattern of lower defaults for NHG loans of the originator. Fitch was also provided with data on historical claims, which enabled the agency to determine a compliance ratio assumption.

Servicing Improvements Implemented
At the time of the previous transaction, Fitch highlighted weaknesses with regards to the IT functionality within the arrears management. NNB has implemented a new IT system, bringing its IT functionality in line with peers.

Hedged Transaction
The issuer will enter into a swap agreement with ING Bank N.V. to hedge the mismatch between the fixed rate mortgages and the floating rate class A1 and A2 notes. Under the swap the issuer will pay: the interest scheduled on the mortgages; less the senior fees; less excess spread of 50 bp per annum of the outstanding notes' balance; times the sum of the class A1 and A2 notes; divided by the total notes' balance. The swap counterparty will pay the interest due on the class A1 and A2 notes, less any recorded principal deficiency.

RATING SENSITIVITIES
Material increases in the frequency of defaults and loss severity on defaulted receivables could produce loss levels wider than Fitch's base case expectations, which in turn may result in rating actions on the notes. Fitch's analysis revealed that a 30% increase in the WA foreclosure frequency, along with a 30% decrease in the WA recovery rate, would result in a model-implied-downgrade of the Class A notes to 'Asf'.

More detail on key rating drivers and rating sensitivities are further described in the accompanying presale report which is available at www.fitchratings.com.

For its ratings analysis, Fitch received a data template with all fields fully completed.

Fitch reviewed the results of an agreed-upon procedures report (AUP) conducted on the portfolio. The AUP reported a higher amount of errors than typically encountered and Fitch has made conservative adjustments in its asset analysis to account for this.

To analyse the credit enhancement levels, Fitch evaluated the collateral using its default model ResiEMEA. The agency assessed the transaction cash flows using default and loss severity assumptions under various structural stresses including prepayment speeds and interest rate scenarios. The cash flow tests showed that each class of notes could withstand loan losses at a level corresponding to the related stress scenario without incurring any principal loss or interest shortfall and ran retire by the legal final maturity.
