EX-99.1 3 d91643_ex99-1.txt CHARACTERISTICS OF THE MORTGAGE POOL Exhibit 99.1 ------------ THE MORTGAGE POOL GENERAL The mortgage pool will initially consist of approximately 970 conventional one- to four- family, fully-amortizing mortgage loans with a principal balance of $162,197,714 as of the Cut-off Date, substantially all of which have fixed rates that are secured by first liens on mortgaged properties. Subsequent to the Closing Date, the Trust will purchase, to the extent available, approximately $37,806,000 in subsequent mortgage loans. The mortgage loans will have original terms to maturity of not greater than 30 years. PREPAYMENT CHARGES Approximately 81.80% of the mortgage loans provide for payment by the mortgagor of a prepayment charge in limited circumstances on prepayments. Generally, these mortgage loans provide for payment of a prepayment charge on some partial or full prepayments made within one year, five years or other period as provided in the related mortgage note from the date of origination of the mortgage loan. No initial mortgage loan provides for payment of a prepayment charge on partial or full prepayments made more than five years from the date of origination of the initial mortgage loan. The amount of the prepayment charge is as provided in the related mortgage note, and the prepayment charge will generally apply if, in any twelve- month period during the first year, five years or other period as provided in the related mortgage note from the date of origination of the initial mortgage loan, the mortgagor prepays an aggregate amount exceeding 20% of the original principal balance of the initial mortgage loan. The amount of the prepayment charge will generally be equal to 6 months' advance interest calculated on the basis of the mortgage rate in effect at the time of the prepayment on the amount prepaid in excess of 20% of the original principal balance of the initial mortgage loan. The prepayment charges may, in certain circumstances, be waived by the Master Servicer or the related subservicer. Some of these prepayment charges may not be enforceable in cases where the mortgagor sells the related mortgaged property. There can be no assurance that the prepayment charges will have any effect on the prepayment performance of the mortgage loans. The Master Servicer or the related subservicer will be entitled to all prepayment charges received on the mortgage loans, and these amounts will not be available for distribution on the Bonds. PRIMARY MORTGAGE INSURANCE AND THE RADIAN LENDER-PAID PMI POLICY Substantially all of the initial mortgage loans with a loan-to-value ratio at origination in excess of 80.00% will be insured by one of the following: (1) a Primary Insurance Policy issued by a private mortgage insurer (other than a Radian Lender-Paid PMI Policy) or (2) the Radian Lender-Paid PMI Policy. Each Primary Insurance Policy will insure against default under each insured mortgage note as follows: (A) for which the outstanding principal balance at origination of such mortgage loan is greater than or equal to 80.01% and up to and including 90.00% of the lesser of the Appraised Value and the sales price, such mortgage loan is covered by a Primary Insurance Policy in an amount equal to at least 20.00% of the Allowable Claim and (B) for which the outstanding principal balance at origination of such mortgage loan exceeded 90.00% of the lesser of the Appraised Value and the sales price, such mortgage loan is covered by a Primary Insurance Policy in an amount equal to at least 22.00% of the Allowable Claim. The Radian Lender-Paid PMI Policy will insure against default under each insured mortgage note as follows: (A) for which the outstanding principal balance at origination of such mortgage loan is greater than or equal to 80.01% and up to and including 89.99% of the lesser of the Appraised Value and the sales price, such mortgage loan is covered in an amount equal to at least 22.00% of the Allowable Claim, (B) for which the outstanding principal balance at origination of such mortgage loan is at least 90.00% and up to and including 95.00% of the lesser of the Appraised Value and the sales price, such mortgage loan is covered in an amount equal to at least 22.00% of the Allowable Claim and (C) for which the outstanding principal balance at origination of such mortgage loan is at least 95.01% and up to and including 97.00% of the lesser of the Appraised Value and the sales price, such mortgage loan is covered in an amount equal to at least 35.00% of the Allowable Claim. With respect to the Radian Lender-Paid PMI Policy, the premium will be payable by the Master Servicer out of interest collections on the mortgage loans at a rate equal to the related Radian PMI Rate. The Radian PMI Rates will range from 0.28% per annum to 1.76% per annum of the Stated Principal Balance of the related Radian PMI Insured Loan. INITIAL MORTGAGE LOAN CHARACTERISTICS The average principal balance of the initial mortgage loans at origination was approximately $167,347. No initial mortgage loan had a principal balance at origination of greater than approximately $800,000 or less than approximately $41,250. The average principal balance of the initial mortgage loans as of the Cut-off Date was approximately $167,214. No initial mortgage loan had a principal balance as of the Cut-off Date of greater than approximately $800,000 or less than approximately $41,219. As of the Cut-off Date, the initial mortgage loans had mortgage rates ranging from approximately 6.250% per annum to approximately 11.625% per annum and the weighted average mortgage rate was approximately 8.082% per annum. The weighted average remaining term to stated maturity of the initial mortgage loans was approximately 339 months as of the Cut-off Date. None of the initial mortgage loans will have a first Due Date prior to February 1, 2002, or after October 1, 2002, or will have a remaining term to stated maturity of less than 177 months or greater than 360 months as of the Cut-off Date. The latest maturity date of any initial mortgage loan is September 1, 2032. The loan-to-value ratio of a mortgage loan secured by a first lien is equal to the ratio, expressed as a percentage, of the principal amount of the loan at origination, to the lesser of the appraised value of the related mortgaged property at the time of origination and the sales price. The weighted average of the loan-to- value ratios at origination of the initial mortgage loans was approximately 82.40%. No loan-to-value ratio at origination of any initial mortgage loan was greater than approximately 100.00% or less than approximately 24.62%. The original mortgages for some of the mortgage loans have been, or in the future may be, at the sole discretion of the master servicer, recorded in the name of Mortgage Electronic Registration Systems, Inc., or MERS, solely as nominee for the seller and its successors and assigns, and subsequent assignments of those mortgages have been, or in the future may be, at the sole discretion of the master servicer, registered electronically through the MERS(R) System. In some other cases, the original mortgage was recorded in the name of the originator of the mortgage loan, record ownership was later assigned to MERS, solely as nominee for the owner of the mortgage loan, and subsequent assignments of the mortgage were, or in the future may be, at the sole discretion of the master servicer, registered electronically through the MERS(R) System. For each of these mortgage loans, MERS serves as mortgagee of record on the mortgage solely as a nominee in an administrative capacity on behalf of the indenture trustee, and does not have any interest in the mortgage loan. Some of the initial mortgage loans were recorded in the name of MERS. For additional information regarding the recording of mortgages in the name of MERS see "Yield on the Bonds -- Yield Sensitivity of the Class M Bonds" in this prospectus supplement. 49 initial mortgage loans, representing approximately 5.70% of the mortgage pool (by aggregate outstanding principal balance of the initial mortgage loans as of the Cut-off Date), are balloon loans. The amount of the balloon payment on each of these initial mortgage loans is substantially in excess of the amount of the scheduled monthly payment on such initial mortgage loan for the period prior to the Due Date of the balloon payment. These initial mortgage loans have a weighted average remaining term to stated maturity of approximately 179 months. None of the initial mortgage loans is a buydown mortgage loan. None of the mortgage loans will be subject to the Home Ownership and Equity Protection Act of 1994 or any comparable state law. Approximately 81.80% of the initial mortgage loans (by aggregate outstanding principal balance of the initial mortgage loans as of the Cut-off Date) provide for prepayment charges. Approximately 41.10% and 8.92% of the initial mortgage loans (by aggregate outstanding principal balance of the initial mortgage loans as of the Cut-off Date) are covered by a Primary Insurance Policy and the Radian Lender-Paid PMI Policy, respectively. For the initial mortgage loans, the weighted average of the Radian PMI Rates for the mortgage loans covered by the Radian Lender-Paid PMI Policy is approximately 0.87% per annum Set forth below is a description of certain additional characteristics of the initial mortgage loans as of the Cut-off Date, except as otherwise indicated.

_________________ (1) All of these initial mortgage loans were reviewed and placed into risk categories based on the credit standards of the Progressive Series Program. Credit grades of A+, A, A-, B, C and CX correspond to Progressive Series I+, I and II, III and III+, IV, V, and VI, respectively. All of the mortgage loans originated pursuant to the Express Priority Refi(TM) Program have been placed in Progressive Express(TM) Programs II and III. SEE "-- UNDERWRITING STANDARDS." (2) These initial mortgage loans were originated under the Seller's Progressive Express(TM) Program. The underwriting for these initial mortgage loans is generally based on the borrower's "FICO" score and therefore these initial mortgage loans do not correspond to the alphabetical risk categories listed above.

No more than approximately 0.71% of the initial mortgage loans (by aggregate outstanding principal balance as of the Cut-off Date) are secured by mortgaged properties located in any one zip code.

In general, in the case of a mortgage loan made for "rate and term" refinance purposes, substantially all of the proceeds are used to pay in full the principal balance of a previous mortgage loan of the mortgagor with respect to a mortgaged property and to pay origination and closing costs associated with such refinancing. Mortgage loans made for "cash-out" refinance purposes may involve the use of the proceeds to pay in full the principal balance of a previous mortgage loan and related costs except that a portion of the proceeds are generally retained by the mortgagor for uses unrelated to the mortgaged property. The amount of these proceeds retained by the mortgagor may be substantial.
