Exhibit 99.1 ------------ The Group I Mortgage Loans consist of approximately 715 fixed-rate Mortgage Loans having an aggregate principal balance as of the Subsequent Cut-off Date of approximately $95,551,210.31, after application of scheduled payments due on or before the Subsequent Cut-off Date whether or not received, and subject to a permitted variance of plus or minus 5%. The Group II Mortgage Loans consist of approximately 1,560 adjustable-rate Mortgage Loans having an aggregate principal balance as of the Subsequent Cut-off Date of approximately $222,457,253.20, after application of scheduled payments due on or before the Subsequent Cut-off Date whether or not received, and subject to a permitted variance of plus or minus 5%. The Mortgage Loans have original terms to maturity of not greater than 30 years from the date on which the first payment was due on each Mortgage Loan. Each Mortgage Loan will accrue interest at the fixed-rate (in the case of the Group I Mortgage Loans) or the adjustable-rate (in the case of the Group II Mortgage Loans) calculated as specified under the terms of the related mortgage note (each such rate, a "Mortgage Rate"). Each Group I Mortgage Loan has a Mortgage Rate that is fixed for the life of such Mortgage Loan. Each Group II Mortgage Loan accrues interest at a Mortgage Rate that is adjustable. Generally, the Group II Mortgage Loans provide for semi-annual adjustment to the Mortgage Rate thereon and for corresponding adjustments to the monthly payment amount due thereon, in each case on each adjustment date applicable thereto (each such date, an "Adjustment Date"); provided, that the first adjustment for the Group II Mortgage Loans will occur after an initial period of two years after origination. On each Adjustment Date for each Group II Mortgage Loan, the Mortgage Rate thereon will be adjusted (subject to rounding) to equal the sum of the applicable Index (as defined below) and a fixed percentage amount (the "Gross Margin"). The Mortgage Rate on each Group II Mortgage Loan will not decrease on the first related Adjustment Date, will not increase by more than 2.000% per annum on the first related Adjustment Date (the "Initial Periodic Rate Cap") and will not increase or decrease by more than 1.000% per annum on any Adjustment Date thereafter (the "Periodic Rate Cap"). Each Mortgage Rate on each Group II Mortgage Loan will not exceed a specified maximum Mortgage Rate over the life of such Mortgage Loan (the "Maximum Mortgage Rate") or be less than a specified minimum Mortgage Rate over the life of such Mortgage Loan (the "Minimum Mortgage Rate"). Effective with the first monthly payment due on each Group II Mortgage Loan after each related Adjustment Date, the monthly payment amount will be adjusted to an amount that will amortize fully the outstanding principal balance of the related Mortgage Loan over its remaining term, and pay interest at the Mortgage Rate as so adjusted. Due to the application of the Periodic Rate Caps and the Maximum Mortgage Rates, the Mortgage Rate on each such Group II Mortgage Loan, as adjusted on any related Adjustment Date, may be less than the sum of the Index and the related Gross Margin, rounded as described herein. None of the Group II Mortgage Loans permits the related mortgagor to convert the adjustable Mortgage Rate thereon to a fixed Mortgage Rate. Approximately 78.55% of the Group I Mortgage Loans and approximately 80.62% of the Group II Mortgage Loans provide for payment by the mortgagor of a prepayment charge on certain principal prepayments, subject to certain limitations in the related mortgage note and limitations upon collection in the Pooling and Servicing Agreement. Generally, each such Mortgage Loan provides for payment of a prepayment charge on certain prepayments made within a defined period set forth in the related Mortgage Note (generally within the first three years but possibly as short as one year from the date of origination of such Mortgage Loan). The amount of the prepayment charge is as provided in the related Mortgage Note. The holders of the Class P Certificates will be entitled to all prepayment charges received on the Mortgage Loans in both Loan Groups, and such amounts will not be available for distribution on the other classes of Certificates. Under certain instances, as described under the terms of the Pooling and Servicing Agreement, the Master Servicer may waive the payment of any otherwise applicable prepayment charge. Investors should conduct their own analysis of the effect, if any, that the prepayment charges, and decisions by the Master Servicer with respect to the waiver thereof, may have on the prepayment performance of the Mortgage Loans. The Depositor makes no representation as to the effect that the prepayment charges, and decisions by the Master Servicer with respect to the waiver thereof, may have on the prepayment performance of the Mortgage Loans. None of the Mortgage Loans are buydown Mortgage Loans. GROUP I MORTGAGE LOAN STATISTICS The average Principal Balance of the Group I Mortgage Loans at origination was approximately $133,682. No Group I Mortgage Loan had a Principal Balance at origination greater than approximately $402,500 or less than approximately $50,000. The average Principal Balance of the Group I Mortgage Loans as of the Subsequent Cut-off Date was approximately $133,638. No Group I Mortgage Loan had a principal balance as of the Subsequent Cut-off Date greater than approximately $402,500 or less than approximately $49,711. The Group I Mortgage Loans had Mortgage Rates as of the Subsequent Cut-off Date ranging from approximately 5.750% per annum to approximately 13.050% per annum, and the weighted average Mortgage Rate on the Group I Mortgage Loans was approximately 7.740% per annum. The weighted average original loan-to-value ratio of the Group I Mortgage Loans was approximately 80.69%. At origination, no Group I Mortgage Loan had an original loan-to-value ratio greater than approximately 95.00% or less than approximately 19.64%. The weighted average remaining term to stated maturity of the Group I Mortgage Loans was approximately 336 months as of the Subsequent Cut-off Date. None of the Group I Mortgage Loans had a first Due Date prior to August 1, 2002 or after February 1, 2003, or will have an original term to stated maturity of less than 180 months or greater than 360 months as of the Subsequent Cut-off Date. The latest maturity date of any Group I Mortgage Loan is January 1, 2033.
