A total of €14.5 billion has been purchased by Oceanarium from four different sellers/originators.

As of October 2011, the portfolio size was €14.5 billion, and consisted of 72,923 mortgage loans (180,704 loan parts) secured by first-ranking residential properties in the Netherlands. The originators of this transaction are ABN AMRO Bank N.V. ("ABN AMRO Bank"), ABN AMRO Hypotheken Groep B.V. ("ABN AMRO Hypotheken Groep"), MoneYou B.V. (“MoneYou”) and WoonNexxt Hypotheken B.V.

Oceanarium Master Issuer B.V., Series 2011-1 issued Class A (A1 – A14), Class B, Class C, Class D and Class E notes. DBRS rates Class A, B, C and D notes only. The Class A notes are rated “AAA (sf)” and have 7.90% of credit enhancement. The Class B notes are rated “AA (sf)” and have 5.70% of credit enhancement. The Class C notes are rated “A (sf)” and have 3.10% of credit enhancement. The Class D notes are rated “BBB (sf)” and have 0.90% of credit enhancement.

The ratings are based upon DBRS review of the following analytical considerations:
•Transaction capital structure and form and sufficiency of available credit enhancement.
•Relevant credit enhancement is in the form of excess spread and subordinate notes.
•The ability of the transaction to withstand stressed cash flow assumptions and repay investors according to terms in which they have invested.
•The transaction parties’ capabilities with respect to originations, underwriting, servicing, and financial strength.
•The credit quality of the collateral and ability of the servicer to perform collection activities on the collateral.
•A review of the legal structure and opinions.

DBRS credit analysis is performed on a loan-level basis and includes a probability of default and loss given default assessment, an originator- and servicer-specific historical performance review, a Dutch housing market and property price trend evaluation, and finally a cash flow simulation based on various stresses to prepayments, timing of defaults and recoveries and interest rates.
