Prepayment Penalty Analysis For each remittance, Clayton reconciles the prepayment penalties that are collected by the servicers and remitted to the trust to ensure all appropriate funds are passed to the certificateholders. Please refer to the Prepayment Penalty Analysis section of this report for details regarding paid-off loans with prepayment penalty flags. The table below provides a summary of Clayton's reconciliation for this remittance.

Mortgage Insurance Clayton actively monitors mortgage insurance (MI) coverage for this deal. Each month, loans with MI are reviewed to ensure that the servicer has followed the appropriate claim filing process, that appropriate claims are paid, and that appropriate proceeds are remitted to the trust. The Mortgage Insurance Watchlist consists of all claims pending for 60+ days. Clayton monitors these claims to ensure that the servicer and MI company are proceeding to resolve the pending claims. Clayton also reviews each coverage rescission to ensure the findings were warranted and disputes them if discrepancies are found. Please refer to the Mortgage Insurance Report section for information regarding MI coverage for this deal. (page) Loss Analysis Loss Issues for Current Month For each remittance, Clayton analyzes each loan-level loss to ensure that the accurate amount of sale, MI, and hazard insurance proceeds are remitted to the trust. We also review these losses to ensure servicing advances, such as escrow advances and foreclosure fees, are reasonable. If any discrepancies are identified, Clayton actively pursues the servicer to mitigate the loss. Please refer to the Loss Analysis section of this report for details regarding losses to the security. Below is a summary of the losses passed through in this remittance.

(page) Section Two Loan-Level Report (page) Loan-Level Report Definitions * FICO(R):: Represents the borrower's credit score at the time of securitization/origination. * Last Paid Date: Either the interest paid-through date or the last contractually due payment made by the borrower. Clayton Fixed Income Services Inc. uses this date to calculate delinquencies. * Valuation: Represents what is believed to be the most accurate known value of a property based on Clayton Fixed Income Services Inc.'s internal formulas. Several value appraisals may exist for a property, yet only what is believed to be the most accurate value according to these formulas is shown on the report. When no value is available, a valuation known as an "internal estimate" is calculated according to an internal formula that adjusts the original value of the property by the Housing Price Index (HPI) and a discount based on credit class. * Liquidation Date: Clayton Fixed Income Services Inc.'s internal estimate of the date on which the loan will liquidate if it proceeds through foreclosure and REO. This date takes into consideration servicing and state foreclosure timelines, as well as an estimated REO marketing period. * Estimated Loss/(Gain): Clayton Fixed Income Services Inc.'s internal estimate of the loss (or gain) that the loan will experience if it liquidates on the Liquidation Date. * Delinquency Status: Indicates the monthly payment and delinquency history for an individual loan. The right-most character specifies the last known delinquency status, according to the following: * C The contractually due payment arrived on time. * 3 The contractually due payment has not arrived within thirty days. * 6 The contractually due payment has not arrived within sixty days. * 9 The contractually due payment has not arrived within ninety days. * F The property is in the process of foreclosure. * R The property is real estate owned (REO). * 0 The mortgage has either liquidated or been paid off. * OTS Delinquency Method: A current loan becomes 30 days delinquent if the scheduled payment is not made by the close of business on the corresponding day of the following month. * MBA Delinquency Method: A current loan becomes 30 days delinquent if the scheduled payment is not made by the close of business on the last day of the month in which the payment was due.
