The Issuer is a EUR 25 billion, fully revolving continuous issuance programme established in October 2011 and backed by prime Dutch mortgage loans originated by subsidiaries of ABN AMRO Bank N.V. (ABN AMRO).

Confirmation of the ratings to the relevant notes is based upon the following analytical considerations:

-- Portfolio performance, in terms of defaults and level of delinquencies, as of the September 2014 payment date.
-- Current available credit enhancement to each class of rated notes to cover the expected losses for the portfolio at the respective rating level.

Delinquencies more than 90 days have been low since the transaction closed. Since March 2014, they have constantly decreased; and currently stand at a value of 0.84%. Cumulative defaults as a percentage of the initial collateral balance are also low at 0.36%.

Credit enhancement for each class of rated notes has increased since the transaction closed due to the repayment of the previously mentioned notes. As a result, credit enhancement for the collective Class A Notes has increased from the original level of 7.90% to 9.5%, the Class B Notes from 5.70% to 6.9%, the Class C Notes from 3.10% to 3.70% and the Class D Notes from 0.90% to 1.1%.

ABN AMRO is the Issuer Account Bank and Asset Swap Counterparty for the transaction. The DBRS public rating of ABN AMRO is above the Minimum Institution Rating given the rating assigned to the collective Class A Notes as described in the DBRS Legal Criteria for European Transactions and DBRS Derivative Criteria for European Structured Finance Transactions.

To assess the impact of the changing the transaction parameters on the rating, DBRS considered the following stress scenarios, as compared to the parameters used to determine the rating (the Base Case):
-- DBRS expected a lifetime base case Probability of Default (PD) and Loss Given Default (LGD) for the pool based on a review of the current receivables. Adverse changes to asset performance may cause stresses to base case assumptions and therefore have a negative effect on credit ratings.
-- The base case PD and LGD of the current pool of mortgages for the Issuer are 1.19% and 28.66%, respectively. At the AAA (sf) rating level the corresponding PD is 18.48% and the LGD is 48.48%. At the AA (sf) rating level the corresponding PD is 11.76% and the LGD is 41.58%. At the A (sf) rating level the corresponding PD is 8.14% and the LGD is 38.12%. At the BBB (sf) rating level the corresponding PD is 4.86% and the LGD is 32.91%.
-- The Risk Sensitivity overview below illustrates the ratings expected if the PD and LGD increase by a certain percentage over the base case assumption. For example, if the LGD increases by 50%, the ratings for the Class A Notes would be expected to remain at AAA (sf), all else equal. If the PD increases by 50%, the ratings for the Class A Notes would be expected to be lowered to AA (high) (sf), all else equal. Furthermore, if both the PD and LGD increase by 50%, the ratings for the Class A Notes would be expected to decrease to A (high) (sf).
