Exhibit 99.1

ANNEX A

The Trust Student Loan Pool as of July 31, 2025

The trust student loans owned by the trust were originally selected from a portfolio of consolidation student loans owned by Student Loan Marketing Association by employing several criteria, including requirements that each trust student loan as of the original cutoff date:
 
was guaranteed as to principal and interest by a guaranty agency under a guarantee agreement and the guaranty agency was, in turn, reinsured by the Department of Education in accordance with the FFELP;
 
contained terms in accordance with those required by the FFELP, the guarantee agreements and other applicable requirements;
 
was more than 120 days past the final disbursement;
 
was not more than 210 days past due;
 
did not have a borrower who was noted in the related records of the servicer as being currently involved in a bankruptcy proceeding; and
 
had special allowance payments, if any, based on the three-month commercial paper rate or the 91-day Treasury bill rate.
 
No trust student loan as of the original cutoff date was subject to the depositor’s or the Student Loan Marketing Association’s prior obligation to sell that loan to a third party. The Student Loan Marketing Association was dissolved on December 31, 2004 and all of its obligations were assumed by its affiliate, Navient Credit Finance Corporation.
 
Unless otherwise specified, all information with respect to the trust student loans is presented as of July 31, 2025, which is the statistical disclosure date.
 
The following tables provide a description of specified characteristics of the trust student loans as of the statistical disclosure date.  The aggregate outstanding principal balance of the loans in each of the following tables includes the principal balance due from borrowers, plus accrued interest of $1,376,581 to be capitalized as of the statistical disclosure date.  Percentages and dollar amounts in any table may not total 100% or whole dollars due to rounding.  The following tables also contain information concerning the total number of loans and total number of borrowers in the portfolio of trust student loans.  For ease of administration, the servicer separates a consolidation loan on its system into two separate loan segments representing subsidized and unsubsidized segments of the same loan.  The following tables reflect those loan segments within the number of loans.  In addition, 1 borrowers has more than one trust student loan.
 
2003-1

The distribution by weighted average interest rate applicable to the trust student loans on any date following the statistical disclosure date may vary significantly from that in the following tables as a result of variations in the effective rates of interest applicable to the trust student loans and in rates of principal reduction.  Moreover, the information below about the weighted average remaining term to maturity of the trust student loans as of the statistical disclosure date may vary significantly from the actual term to maturity of any of the trust student loans as a result of prepayments or the granting of deferment and forbearance periods.
 
The following tables also contain information concerning the total number of loans and the total number of borrowers in the portfolio of trust student loans.
 
Percentages and dollar amounts in any table may not total 100% of the trust student loan balance, as applicable, due to rounding.

We determined the weighted average remaining term to maturity shown in the table from the statistical disclosure date to the stated maturity date of the applicable trust student loan without giving effect to any deferment or forbearance periods that may be granted in the future.  See Appendix A to the preliminary remarketing memorandum.
 
The weighted average annual borrower interest rate shown in the table is exclusive of special allowance payments.  The weighted average spread for special allowance payments to the 91-day Treasury bill rate was 3.10% as of the statistical disclosure date.
 
The weighted average spread for special allowance payments to the 30-day Average SOFR Rate was 2.64% as of the statistical disclosure date.  See “Special Allowance Payments” in Appendix A to the preliminary remarketing memorandum.
 
For these purposes, the 91-day Treasury bill rate is the weighted average per annum discount rate, expressed on a bond equivalent basis and applied on a daily basis, for direct obligations of the United States with a maturity of thirteen weeks, as reported by the United States Department of the Treasury.

We determined the interest rates shown in the table above using the interest rates applicable to the trust student loans as of the statistical disclosure date.  Because trust student loans with different interest rates are likely to be repaid at different rates, this information is not likely to remain applicable to the trust student loans after the statistical disclosure date.  See Appendix A to the preliminary remarketing memorandum and “The Student Loan Pools – Sallie Mae’s Student Loan Financing Business” in the original prospectus.

Current borrower payment status refers to the status of the borrower of each trust student loan as of the statistical disclosure date.  The borrower:
 
may have temporarily ceased repaying the loan through a deferment or a forbearance period; or
 
may be currently required to repay the loan – repayment.
 
See Appendix A to the preliminary remarketing memorandum and “The Student Loan Pools –Sallie Mae’s Student Loan Financing Business” in the original prospectus.
 
The weighted average number of months in repayment for all trust student loans currently in repayment is approximately 152.7 calculated as the term to maturity at the commencement of repayment less the number of months remaining to scheduled maturity as of the statistical disclosure date.

We have determined the scheduled weighted average remaining months in status shown in the previous table without giving effect to any deferment or forbearance periods that may be granted in the future.  Of the $4,645,694 aggregate outstanding principal balance of the trust student loans in deferment as of the statistical disclosure date, $3,516,233 or approximately 75.7% of such loans are to borrowers who had not graduated as of that date.  We expect that a significant portion of these loans could qualify for additional deferments or forbearances at the end of their current deferment periods as the related borrowers continue their education beyond their current degree programs.  As a result, the overall duration of any applicable deferment and forbearance periods as well as the likelihood of future deferment and forbearance periods within this pool of trust student loans is likely to be higher than in other pools of student loans without similar numbers of in-school consolidation loans.  See Appendix A to the original prospectus.

We have based the geographic distribution shown in the table on the billing addresses of the borrowers of the trust student loans shown on the servicer’s records as of the statistical disclosure date.
 
Each of the trust student loans provides or will provide for the amortization of its outstanding principal balance over a series of regular payments.  Except as described below, each regular payment consists of an installment of interest which is calculated on the basis of the outstanding principal balance of the trust student loan.  The amount received is applied first to interest accrued to the date of payment and the balance of the payment, if any, is applied to reduce the unpaid principal balance.  Accordingly, if a borrower pays a regular installment before its scheduled due date, the portion of the payment allocable to interest for the period since the preceding payment was made will be less than it would have been had the payment been made as scheduled, and the portion of the payment applied to reduce the unpaid principal balance will be correspondingly greater.  Conversely, if a borrower pays a monthly installment after its scheduled due date, the portion of the payment allocable to interest for the period since the preceding payment was made will be greater than it would have been had the payment been made as scheduled, and the portion of the payment applied to reduce the unpaid principal balance will be correspondingly less.
 
In either case, subject to any applicable deferment periods or forbearance periods, and except as provided below, the borrower pays a regular installment until the final scheduled payment date, at which time the amount of the final installment is increased or decreased as necessary to repay the then outstanding principal balance of that trust student loan.
 
The servicer makes available to borrowers of student loans it holds (including the trust student loans) payment terms that may result in the lengthening of the remaining term of the student loans.  For example, not all of the loans sold to the trust provide for level payments throughout the repayment term of the loans.  Some student loans provide for interest only payments to be made for a designated portion of the term of the loans, with amortization of the principal of the loans occurring only when payments increase in the latter stage of the term of the loans.  Other loans provide for a graduated phase in of the amortization of principal with a greater portion of principal amortization being required in the latter stages than would be the case if amortization were on a level payment basis.  The servicer also offers an income-sensitive repayment plan, under which repayments are based on the borrower’s income.  Under that plan, ultimate repayment may be delayed up to five years.  Borrowers under trust student loans will continue to be eligible for the graduated payment and income-sensitive repayment plans.  These programs are applicable to the trust student loans and may be offered by the servicer to related borrowers at its discretion.

With respect to interest-only loans, as of the statistical disclosure date, there are 51 loans with an aggregate outstanding principal balance of $2,560,513 currently in an interest-only period.  These interest-only loans represent approximately 1.4% of the aggregate outstanding principal balance of the trust student loans.  Interest-only periods range up to 48 months in overall length.
 
The servicer may in the future offer repayment terms similar to those described above to borrowers of trust student loans who are not entitled to these repayment terms as of the statistical disclosure date.  If repayment terms are offered to and accepted by those borrowers, the weighted average life of the securities could be lengthened.
