All of the mortgage loans in the aforementioned transactions were either originated or acquired by ABN AMRO Mortgage Group. The mortgage loans consist of 15- and/or 30-year, fixed-rate mortgages secured by first liens on one- to four-family residential properties. As of the December 2006 distribution date, the transactions are seasoned from a range of 12 to 47 months and the pool factors (current mortgage loan principal outstanding as a percentage of the initial pool) range from approximately 25% to 93%. ABN AMRO Mortgage Group, rated 'RPS2' by Fitch, currently services all of the mortgage loans in these transactions.

The affirmations reflect a satisfactory relationship between credit enhancement (CE) and future loss expectations and affect approximately $4.823 billion of outstanding certificates. The upgrades reflect an improvement in the relationship between CE and future loss expectations and affect approximately $19.9 million of outstanding certificates. The CE levels for all the upgraded classes have at least doubled since closing. As of the December 2006 distribution date, all of the pools have experience little to no losses.

The Armor MCP 2005-1 transaction is a synthetic balance sheet securitization that references a diversified portfolio of primarily jumbo, A-quality, first lien residential mortgage loans. The ratings are based upon the credit quality of the reference portfolio, the credit enhancement provided by subordination for each tranche, the financial strength of LaSalle Bank Corporation (LaSalle), as the swap counterparty. The issuers have

entered into a credit default swap (CDS) with LaSalle, documented under an International Swaps and Derivatives Association agreement, and receive a premium in return for credit protection on the reference portfolio.

Fitch will closely monitor these transactions. Further information regarding current delinquency, loss, and credit enhancement statistics is available on the Fitch Ratings website at www.fitchratings.com.
