The affirmations, affecting approximately $314,938,093 of the outstanding balances, are taken due to a satisfactory relationship of credit enhancement to expected losses.

In AMSI series 2002-C, class M2 is downgraded due to monthly losses which have generally exceeded excess spread and caused deterioration in the overcollateralization (OC) amount. As of the November 2006 distribution, the OC amount of $2,122,961.06 is below the target amount of $6,500,000.

As of the cut-off date, the collateral for series 2002-C had a weighted average original loan-to-value (OLTV) of 78.10%, and consists primarily of loans for the purpose of refinance. The balance of collateral in states which have averaged annual home price appreciation below the national average has increased from 36% of current balance at origination to 62% of current balance in November.

In AMSI series 2003-6, classes M5 and M6 (approximately $36.49 million outstanding in aggregate) are placed on Rating Watch Negative due to monthly losses exceeding the available excess spread in recent months, which has caused deterioration in the overcollateralization (OC) amount. As of the November 2006 distribution, the OC amount of $6,978,833 is below the target amount of $8,902,438.

As of the cut-off date, the collateral for series 2003-6 had a weighted average original loan-to-value (OLTV) of 79.32%, and all of the loans from the trust were for the purpose of refinance. The balance of collateral in states which have averaged annual home price appreciation below the national average has increased from 35% of current balance at origination to 57% of current balance in November.

The underlying collateral consists of fully amortizing 15 to 30 year fixed and adjustable rate mortgages secured by first liens extended to subprime borrowers. As of the November distribution date, the transactions listed above are seasoned from 48 (2002-C) to 42 (2003-6) months. The pool factors (current principal balance as a percentage of original) range approximately from 9% (2002-C) to 17% (2003-6).

The Ameriquest Securities (AMSI) loans, the retail sector for the Ameriquest Mortgage Securities Inc., were either originated or acquired by Ameriquest Mortgage Company. Ameriquest Mortgage Company serves as the servicer for the loans and is rated 'RPS2+' by Fitch.
