(The following statement was released by the rating agency)
Aug 21 - Standard & Poor's Ratings Services today assigned its preliminary ratings to the four classes of prime residential mortgage-backed securities (RMBS) issued by Perpetual Trustee Company Ltd. as trustee of Progress 2012-2 Trust (see list). Progress 2012-2 Trust is a securitization of prime residential mortgages originated by AMP Bank Ltd.
The preliminary ratings reflect:
-- Our view of the credit risk of the underlying collateral portfolio, including the fact that this is a closed portfolio, which means no further loans will be assigned to the trust after the closing date.
-- Our view that the credit support is sufficient to withstand the stresses we apply. This credit support comprises note subordination and overcollateralization for each class of rated note.
-- The benefit of a fixed-to-floating interest-rate swap to be provided by AMP Bank Ltd. (A/Stable/A-1) to hedge the mismatch between receipts from any fixed-rate mortgage loans and the variable-rate RMBS.
-- Our expectation that the various mechanisms to support liquidity within the transaction, including a liquidity reserve equal to 1.5% of the invested amount of the notes, and principal draws, are sufficient under our stress assumptions to ensure timely payment of interest.
