Exhibit 99.1

      Unless otherwise noted, all statistical percentages or weighted averages
given as of the Subsequent Cut-off Date set forth herein are measured as a
percentage of the aggregate Principal Balance of the Initial Mortgage Loans in
the related Loan Group or in the Mortgage Pool as of the Cut-off Date and the
Subsequent Mortgage Loans in the related Loan Group or in the Mortgage Pool as
of the Subsequent Cut-off Date.

      The Group I Mortgage Loans consist of approximately 2,973 Mortgage Loans
with a Subsequent Cut-off Date Principal Balance of approximately $345,208,640 .
The Group II Mortgage Loans consist of approximately 2,456 Mortgage Loans with a
Subsequent Cut-off Date Principal Balance of approximately $345,233,403.

      All of the Mortgage Loans will be secured by first or second mortgages or
deeds of trust or other similar security instruments (each, a "Mortgage"). The
Mortgages create first or second liens on one- to four-family residential
properties consisting of attached or detached one- to four- family dwelling
units and individual condominium units (each, a "Mortgaged Property").

      Each Mortgage Loan will accrue interest at the adjustable-rate or
fixed-rate calculated as specified under the terms of the related mortgage note
(each such rate, a "Mortgage Rate"). Approximately 91.81 % of the Group I
Mortgage Loans are adjustable-rate Mortgage Loans (the "Adjustable-Rate Group I
Mortgage Loans") and approximately 8.19% of the Group I Mortgage Loans are
fixed-rate Mortgage Loans (the "Fixed-Rate Group I Mortgage Loans").
Approximately 91.17% of the Group II Mortgage Loans are adjustable-rate Mortgage
Loans (the "Adjustable-Rate Group II Mortgage Loans") and approximately 8.83% of
the Group II Mortgage Loans are fixed-rate Mortgage Loans (the "Fixed-Rate Group
II Mortgage Loans"). Approximately 91.49% of the Mortgage Loans are
adjustable-rate Mortgage Loans (the "Adjustable-Rate Mortgage Loans") and
approximately 8.51% of the Mortgage Loans are fixed-rate Mortgage Loans (the
"Fixed-Rate Mortgage Loans").

      Each fixed-rate Mortgage Loan has a Mortgage Rate that is fixed for the
life of such Mortgage Loan.

      Each adjustable-rate Mortgage Loan accrues interest at a Mortgage Rate
that is adjustable following an initial period of two years or three years
following origination. Generally, the adjustable-rate 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, (i) the first adjustment of the rates for approximately 61.17% of the
Adjustable-Rate Group I Mortgage Loans and approximately 69.15% of the
Adjustable-Rate Group II Mortgage Loans, (in each case, by aggregate principal
balance of the Adjustable-Rate Mortgage Loans in the related Loan Group as of
the Subsequent Cut-off Date) and approximately 68.16% of the Adjustable-Rate
Mortgage Loans (by aggregate principal balance of the Adjustable-Rate Mortgage
Loans) will not occur until two years after the date of origination and (ii) the
first adjustment of the rates for approximately 24.52% of the Adjustable-Rate
Group I Mortgage Loans and approximately 21.63% of the Adjustable-Rate Group II
Mortgage Loans, (in each case, by aggregate principal balance of the
Adjustable-Rate Mortgage Loans in the related Loan Group as of the Subsequent
Cut-off Date) and approximately 23.07% of the Adjustable-Rate Mortgage Loans (by
aggregate principal balance of the Adjustable-Rate Mortgage Loans) will not
occur until three years after the date of origination (each adjustable-rate
Mortgage Loan having any such two year or three year initial fixed period, a
"Delayed First Adjustment Mortgage Loan"). On each Adjustment Date for each
adjustable-rate Mortgage Loan, the Mortgage Rate thereon will be adjusted to
equal the sum, rounded as provided in the related mortgage note, of Six-Month
LIBOR (as defined below), and a fixed percentage amount (the "Gross Margin").
The Mortgage Rate on any adjustable-rate Mortgage Loan will not decrease on the
first related Adjustment Date, will not increase by more than a stated
percentage on the first related Adjustment Date (the "Periodic Rate Cap") and
will not increase or decrease by more than a stated percentage on any Adjustment
Date thereafter (the "Periodic Rate Cap"). Each Mortgage Rate on each
adjustable-rate 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 adjustable-rate 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 adjustable-rate 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, the Periodic Rate Caps and the Maximum Mortgage Rates, the
Mortgage Rate on each adjustable-rate 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 in this prospectus supplement. None of the
adjustable-rate Mortgage Loans will permit the related mortgagor to convert the
adjustable Mortgage Rate thereon to a fixed Mortgage Rate.

      Approximately 17.39% of the Mortgage Loans provide that for a period of 24
months after origination and approximately 3.09% of the Mortgage Loans provide
that for a period of 36 months after origination (the "Interest Only Mortgage
Loans"), the required monthly payments are limited to accrued interest (each, an
"Interest Only Period"). At the end of the Interest Only Period, the monthly
payments on each such Mortgage Loan will be recalculated to provide for
amortization of the Principal Balance by the maturity date and payment of
interest at the then-current Mortgage Rate.

      Approximately 85.80% of the Group I Mortgage Loans and approximately
87.71% of the Group II Mortgage Loans (in each case, by aggregate principal
balance of the Mortgage Loans in the related Loan Group as of the Subsequent
Cut-off Date) and approximately 86.75% of the Mortgage Loans (by aggregate
principal balance of the Mortgage Loans) provide for payment by the mortgagor of
a prepayment charge in limited circumstances on certain prepayments. Generally,
each such Mortgage Loan provides for payment of a prepayment charge on partial
prepayments and prepayments in full made within a stated number of months that
is generally between 12 and 36 months from the date of origination of such
Mortgage Loan. The amount of the prepayment charge is provided in the related
mortgage note and is generally equal to six months' interest on any amounts
prepaid in excess of 20.00% of the original Principal Balance of the related
Mortgage Loan in any 12 month period. The holders of the Class P Certificates
will be entitled to all prepayment charges received on the Mortgage Loans, and
such amounts will not be available for distribution on the other classes of
Certificates. Under certain circumstances, as described in the Pooling
Agreement, the 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 Servicer with respect to
the waiver thereof, may have on the prepayment performance of the Mortgage
Loans. As of July 1, 2003, the Alternative Mortgage Parity Act of 1982 (the
"Parity Act"), which regulates the ability of some originators to impose
prepayment charges, was amended. The Depositor makes no representations as to
the effect that the prepayment charges, decisions by the Servicer with respect
to the waiver thereof and the recent amendment of the Parity Act, may have on
the prepayment performance of the Mortgage Loans. However, the Office of Thrift
Supervision's ruling does not retroactively affect loans originated before July
1, 2003.

Mortgage Loan Statistics for all Mortgage Loans

      Approximately 47.37% of the Mortgage Loans had combined loan-to-value
ratios at origination in excess of 80.00%. No Mortgage Loan had a combined
loan-to-value ratio at origination in excess of 100.00%. The weighted average
combined loan-to-value ratio of the Mortgage Loans at origination was
approximately 86.46%. There can be no assurance that the loan-to-value ratio of
any Mortgage Loan determined at any time after origination is less than or equal
to its original loan-to-value ratio. Additionally, the Originator's
determination of the value of a Mortgaged Property used in the calculation of
the original loan-to-value ratios of the Mortgage Loans may differ from the
appraised value of such Mortgaged Property or the actual value of such Mortgaged
Property at origination.



      All of the Mortgage Loans have a scheduled payment due each month (the
"Due Date") on the first day of the month.

      The weighted average remaining term to maturity of the Mortgage Loans was
approximately 348 months as of the Subsequent Cut-off Date. None of the Mortgage
Loans had a first Due Date prior to April 1, 2003 or after May 1, 2004, or has a
remaining term to maturity of less than 170 months or greater than 360 months as
of the Subsequent Cut-off Date. The latest maturity date of any Mortgage Loan is
April 1, 2034.

      The average Principal Balance of the Mortgage Loans at origination was
approximately $127,389. The average Subsequent Cut-off Date Principal Balance of
the Mortgage Loans was approximately $127,177. No Mortgage Loan had a Subsequent
Cut-off Date Principal Balance of greater than approximately $719,283 or less
than approximately $7,643.

      As of the Subsequent Cut-off Date, the Mortgage Loans had Mortgage Rates
of not less than 4.625% per annum and not more than 16.490% per annum and the
weighted average Mortgage Rate of the Mortgage Loans was approximately 7.857%
per annum. As of the Subsequent Cut-off Date, the Adjustable-Rate Mortgage Loans
had Gross Margins ranging from 3.875% per annum to 10.000% per annum, Minimum
Mortgage Rates ranging from 4.000% per annum to 12.875% per annum and Maximum
Mortgage Rates ranging from 7.000% per annum to 19.875% per annum. As of the
Subsequent Cut-off Date, the weighted average Gross Margin of the
Adjustable-Rate Mortgage Loans was approximately 6.188% per annum, the weighted
average Minimum Mortgage Rate of the Adjustable-Rate Mortgage Loans was
approximately 7.569% per annum and the weighted average Maximum Mortgage Rate of
the Adjustable-Rate Mortgage Loans was approximately 14.658% per annum. The
latest next Adjustment Date following the Subsequent Cut-off Date on any
Adjustable-Rate Mortgage Loan occurs on April 1, 2009 and the weighted average
time until the next Adjustment Date for all of the Adjustable-Rate Mortgage
Loans is approximately 24 months.

      The Mortgage Loans are expected to have the following characteristics as
of the Subsequent Cut-off Date (the sum in any column may not equal the total
indicated due to rounding):

Group I Mortgage Loan Statistics

      Approximately 47.97% of the Group I Mortgage Loans had combined
loan-to-value ratios at origination in excess of 80.00%. No Group I Mortgage
Loan had a combined loan-to-value ratio at origination in excess of 100.00%. The
weighted average combined loan-to-value ratio of the Group I Mortgage Loans at
origination was approximately 86.76%. There can be no assurance that the
loan-to-value ratio of any Group I Mortgage Loan determined at any time after
origination is less than or equal to its original loan-to-value ratio.
Additionally, the Originator's determination of the value of a Mortgaged
Property used in the calculation of the original loan-to-value ratios of the
Mortgage Loans may differ from the appraised value of such Mortgaged Property or
the actual value of such Mortgaged Property at origination.

      All of the Group I Mortgage Loans have a scheduled payment due each month
(the "Due Date") on the first day of the month.

      The weighted average remaining term to maturity of the Group I Mortgage
Loans was approximately 349 months as of the Subsequent Cut-off Date. None of
the Group I Mortgage Loans had a first Due Date prior to April 1, 2003 or after
May 1, 2004, or has a remaining term to maturity of less than 170 months or
greater than 360 months as of the Subsequent Cut-off Date. The latest maturity
date of any Group I Mortgage Loan is April 1, 2034.



      The average Principal Balance of the Group I Mortgage Loans at origination
was approximately $116,319. The average Subsequent Cut-off Date Principal
Balance of the Group I Mortgage Loans was approximately $116,115. No Group I
Mortgage Loan had a Subsequent Cut-off Date Principal Balance of greater than
approximately $600,000 or less than approximately $7,643.

      As of the Subsequent Cut-off Date, the Group I Mortgage Loans had Mortgage
Rates of not less than 4.625% per annum and not more than 16.490% per annum and
the weighted average Mortgage Rate of the Group I Mortgage Loans was
approximately 7.994% per annum. As of the Subsequent Cut-off Date, the
Adjustable-Rate Group I Mortgage Loans had Gross Margins ranging from 3.875% per
annum to 10.000% per annum, Minimum Mortgage Rates ranging from 4.000% per annum
to 12.875% per annum and Maximum Mortgage Rates ranging from 7.000% per annum to
19.875% per annum. As of the Subsequent Cut-off Date, the weighted average Gross
Margin of the Adjustable-Rate Group I Mortgage Loans was approximately 6.227%
per annum, the weighted average Minimum Mortgage Rate of the Adjustable-Rate
Group I Mortgage Loans was approximately 7.702% per annum and the weighted
average Maximum Mortgage Rate of the Adjustable-Rate Group I Mortgage Loans was
approximately 14.805% per annum. The latest next Adjustment Date following the
Subsequent Cut-off Date on any Adjustable-Rate Group I Mortgage Loan occurs in
April 1, 2009 and the weighted average time until the next Adjustment Date for
all of the Adjustable-Rate Group I Mortgage Loans is approximately 24 months.

      The Group I Mortgage Loans are expected to have the following
characteristics as of the Subsequent Cut-off Date (the sum in any column may not
equal the total indicated due to rounding):

Group II Mortgage Loan Statistics

      Approximately 46.77% of the Group II Mortgage Loans had combined
loan-to-value ratios at origination in excess of 80.00%. No Group II Mortgage
Loan had a combined loan-to-value ratio at origination in excess of 100.00%. The
weighted average combined loan-to-value ratio of the Group II Mortgage Loans at
origination was approximately 86.16%. There can be no assurance that the
loan-to-value ratio of any Group II Mortgage Loan determined at any time after
origination is less than or equal to its original loan-to-value ratio.
Additionally, the Originator's determination of the value of a Mortgaged
Property used in the calculation of the original loan-to-value ratios of the
Mortgage Loans may differ from the appraised value of such Mortgaged Property or
the actual value of such Mortgaged Property at origination.

      All of the Group II Mortgage Loans have a scheduled payment due each month
(the "Due Date") on the first day of the month.

      The weighted average remaining term to maturity of the Group II Mortgage
Loans was approximately 348 months as of the Subsequent Cut-off Date. None of
the Group II Mortgage Loans had a first Due Date prior to June 1, 2003 or after
May 1, 2004, or has a remaining term to maturity of less than 170 months or
greater than 360 months as of the Subsequent Cut-off Date. The latest maturity
date of any Group II Mortgage Loan is April 1, 2034.

      The average Principal Balance of the Group II Mortgage Loans at
origination was approximately $140,789. The average Subsequent Cut-off Date
Principal Balance of the Group II Mortgage Loans was approximately $140,567. No
Group II Mortgage Loan had a Subsequent Cut-off Date Principal Balance of
greater than approximately $719,283 or less than approximately $9,832.

      As of the Subsequent Cut-off Date, the Group II Mortgage Loans had
Mortgage Rates of not less than 4.625% per annum and not more than 16.250% per
annum and the weighted average Mortgage Rate of the Group II Mortgage Loans was
approximately 7.720% per annum. As of the Subsequent Cut-off Date, the
Adjustable-Rate Group II Mortgage Loans had Gross Margins ranging from 3.875%
per annum to 10.000% per annum, Minimum Mortgage Rates ranging from 4.375% per
annum to 12.750% per annum and Maximum Mortgage Rates ranging from 9.125% per
annum to




19.750% per annum. As of the Subsequent Cut-off Date, the weighted average Gross
Margin of the Adjustable-Rate Group II Mortgage Loans was approximately 6.150%
per annum, the weighted average Minimum Mortgage Rate of the Adjustable-Rate
Group II Mortgage Loans was approximately 7.435% per annum and the weighted
average Maximum Mortgage Rate of the Adjustable-Rate Group II Mortgage Loans was
approximately 14.509% per annum. The latest next Adjustment Date following the
Subsequent Cut-off Date on any Adjustable-Rate Group II Mortgage Loan occurs in
April 1, 2009 and the weighted average time until the next Adjustment Date for
all of the Adjustable-Rate Group II Mortgage Loans is approximately 24 months.

      The Group II Mortgage Loans are expected to have the following
characteristics as of the Subsequent Cut-off Date (the sum in any column may not
