GLOSSARY

Listed below are definitions of key terms that are used throughout this document.

Consolidation Loans—Under the FFELP, borrowers with eligible student loans may consolidate them into one note with one lender and convert the variable interest rates on the loans being consolidated into a fixed rate for the life of the loan. The new note is considered a Consolidation Loan. Typically a borrower can consolidate their student loans only once unless the borrower has another eligible loan with which to consolidate with the existing Consolidation Loan. The borrower rate on a Consolidation Loan is fixed for the term of the loan and is set by the weighted-average interest rate of the loans being consolidated, rounded up to the nearest 1/8^th of a percent, not to exceed 8.25 percent. In low interest rate environments, Consolidation Loans provide an attractive refinancing opportunity because they allow borrowers to consolidate variable rate loans into a long-term fixed rate loan.

Consolidation Loan Rebate Fee—All holders of Consolidation Loans are required to pay to the U.S. Department of Education an annual 105 basis point Consolidation Loan Rebate Fee on all outstanding principal and accrued interest balances of Consolidation Loans purchased or originated after October 1, 1993, except for loans for which consolidation applications were received between October 1, 1998 and January 31, 1999, where the Consolidation Loan Rebate Fee is 62 basis points.

Constant Prepayment Rate ("CPR")—A variable in life of loan estimates that measures the rate at which loans in the portfolio pay before their stated maturity. The CPR is directly correlated to the average life of the portfolio.

DOE—The U.S. Department of Education.

Direct Loans—Student loans originated directly by the DOE under the William D. Ford Federal Direct Student Loan Program.

Embedded Floor Income—Embedded Floor Income is Floor Income (see definition below) that is earned on off-balance sheet student loans that are in securitization trusts sponsored by us. At the time of the securitization, the option value of Embedded Fixed Rate Floor Income is included in the initial calculation of the Residual Interest and the gain or loss on sale of the student loans. Embedded Floor Income is also included in the quarterly fair value adjustments of the Residual Interest.

Fixed Rate Floor Income—We refer to Floor Income associated with student loans whose borrower rate is fixed to term (primarily Consolidation Loans) as Fixed Rate Floor Income.

Floor Income—Our portfolio of FFELP student loans earns interest at the higher of a floating rate based on the Special Allowance Payment or SAP formula (see definition below) set by the DOE and the borrower rate, which is fixed over a period of time. We generally finance our student loan portfolio with floating rate debt over all interest rate levels. In low and/or declining interest rate environments, when the fixed borrower rate is higher than the rate produced by the SAP formula, our student loans earn at a fixed rate while the interest on our floating rate debt continues to decline. In these interest rate environments, we earn additional spread income that we refer to it as Floor Income. Depending on the type of the student loan and when it was originated, the borrower rate is either fixed to term or is reset to a market rate each July 1. As a result, for loans where the borrower rate is fixed to term, we may earn Floor Income for an extended period of time, and for those loans where the borrower interest rate is reset annually on July 1, we may earn Floor Income to the next reset date.

The following example shows the mechanics of Floor Income for a fixed rate Consolidation Loan with a T-bill based SAP spread of 3.10 percent:

Fixed borrower interest rate:	8.25	%
SAP spread over 91-day T-bill:	(3.10	)%

Floor strike rate¹:	5.15	%

¹: The interest rate at which the underlying index (Treasury bill or commercial paper) plus the fixed SAP spread equals the fixed borrower rate. Floor Income is earned anytime the interest rate of the underlying index declines below this rate.

Based on this example, if the quarterly average 91-day Treasury bill rate is over 5.15 percent, the holder of the student loan will earn at a floating rate based on the SAP formula, which in this example is a fixed spread to Treasury bills of 3.10 percent. On the other hand, if the quarterly average 91-day Treasury bill is below 5.15 percent, the SAP formula will produce a rate below the fixed borrower rate of 8.25 percent and the loan holder earns at the borrower rate of 8.25 percent. The difference between the fixed borrower rate and the lender's expected yield based on the SAP formula is referred to as Floor Income. Our student loan assets are generally funded with floating rate debt, so when student loans are earning at the fixed borrower rate, declines in interest rates increase Floor Income.

Graphic Depiction of Floor Income:

FFELP—The Federal Family Education Loan Program, formerly the Guaranteed Student Loan Program.

FDLP—The William D. Ford Federal Direct Student Loan Program.

Floor Income Contracts—We enter into contracts with counterparties under which, in exchange for an upfront fee representing the present value of the Floor Income that we expect to earn on a notional amount of student loans being hedged, we will pay the counterparties the Floor Income earned on that notional amount of student loans over the life of the Floor Income Contract. Specifically, we agree to pay the counterparty the difference, if positive, between the fixed borrower rate less the SAP spread and the average of the applicable interest rate index on that notional amount of student loans for a

portion of the estimated life of the student loan. This contract effectively locks in the amount of Floor Income we will earn over the period of the contract. Floor Income Contracts are not considered effective hedges under Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging Activities," and each quarter we must record the change in fair value of these contracts through income.

GSE—The Student Loan Marketing Association is a federally chartered government-sponsored enterprise and wholly owned subsidiary of SLM Corporation.

HEA—The Higher Education Act of 1965, as amended.

Managed Basis—We generally analyze the performance of our student loan portfolio on a Managed Basis, under which we view both on-balance sheet student loans and off-balance sheet student loans owned by the securitization trusts as a single portfolio and the related on-balance sheet financings are combined with off-balance sheet debt. When the term Managed is capitalized in this document, it is referring to Managed Basis. All Managed Basis presentations are considered non-GAAP measures of performance.

Offset Fee—We are required to pay to the DOE an annual 30 basis point Offset Fee on the outstanding balance of Stafford and PLUS student loans purchased and held by the GSE after August 10, 1993. The fee does not apply to student loans sold to securitized trusts or to loans held outside of the GSE.

Preferred Channel Originations—Preferred Channel Originations are comprised of: 1) student loans that are originated or serviced on our proprietary platforms, and are committed for sale to Sallie Mae, such that we either own them from inception or acquire them soon after origination, and 2) loans that are originated and serviced on other platforms on behalf of Sallie Mae owned brands and our lending partners, Bank One and JPMorgan Chase, and are committed for sale to Sallie Mae. (See also "RECENT DEVELOPMENTS—Bank One Agreement" for a discussion related to our lender partners.)

Preferred Lender List—To streamline the student loan process, most higher education institutions select a small number of lenders to recommend to their students and parents. This recommended list is referred to as the Preferred Lender List.

Private Credit Student Loans—Education loans to students or parents of students that are not guaranteed or reinsured under the FFELP or any other federal student loan program. Private Credit Student Loans include loans for traditional higher education with repayment terms that begin after graduation, similar to the FFELP, and for alternative education, such as career training, that require repayment immediately.

Privatization Act—The Student Loan Marketing Association Reorganization Act of 1996.

Residual Interest—When we securitize student loans, we retain the right to receive cash flows from the student loans sold in excess of amounts needed to pay servicing and other fees and the principal and interest on the bonds backed by the student loans. The Residual Interest is the present value of the future expected cash flows from off-balance sheet student loans in securitized trusts, which includes the present value of Embedded Fixed Rate Floor Income described above. We value the Residual Interest at the time of sale and at each subsequent quarter.

Retained Interest—In our securitizations the Retained Interest includes the Residual Interest plus reserve and other cash accounts that serve as credit enhancements to asset-backed securities issued in our securitizations.

Risk Sharing—When a FFELP loan defaults, the federal government guarantees 98 percent of the principal balance plus accrued interest and the holder of the loan must absorb the two percent not

guaranteed as a Risk Sharing loss on the loan. FFELP student loans acquired after October 1, 1993 are subject to Risk Sharing on loan default claim payments unless the default results from death, disability or bankruptcy, except for certain FFELP loans serviced by third parties with an Exceptional Performer designation from the DOE.

Special Allowance Payment ("SAP")—FFELP student loans generally earn interest at the greater of the borrower rate or a floating rate determined by reference to the average of the applicable floating rates (91-day Treasury bill rate or commercial paper) in a calendar quarter, plus a fixed spread that is dependent upon when the loan was originated and the loan's repayment status. If the resulting floating rate exceeds the borrower rate, the DOE pays the difference directly to us. This payment is referred to as the Special Allowance Payment or SAP and the formula used to determine the floating rate is the SAP formula. We refer to the fixed spread to the underlying index as the Special Allowance margin.

Title IV Programs and Title IV Loans—Student loan programs created under Title IV of the HEA, including the FFELP and the FDLP, and student loans originated under those programs, respectively.

Wind-Down—The dissolution of the Student Loan Marketing Association (the "GSE") under the terms of the Privatization Act.

Wind-Down Period—The period during which the Student Loan Marketing Association is dissolved under the terms of the Privatization Act.

Variable Rate Floor Income—For student loans whose borrower interest rate resets annually on July 1, we may earn Floor Income or Embedded Floor Income based on a calculation of the difference between the borrower rate and the then current interest rate. We refer to this as Variable Rate Floor Income because Floor Income is earned only through the next reset date.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Information at June 30, 2004 and for the three and six months ended
June 30, 2004 and 2003 is unaudited)
(Dollars and shares in thousands, except per share amounts, unless otherwise stated)

1. Significant Accounting Policies

Basis of Presentation

The accompanying unaudited consolidated financial statements of SLM Corporation (the "Company") have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments considered necessary for a fair statement of the results for the interim periods have been included. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Operating results for the three and six months ended June 30, 2004 are not necessarily indicative of the results for the year ending December 31, 2004. These unaudited financial statements should be read in conjunction with the audited financial statements and related notes included in the Company's 2003 Annual Report on Form 10-K.

Privatization Act—GSE Wind-Down Update

Under the Privatization Act, the GSE must wind down its operations and dissolve on or before September 30, 2008. As of June 2004, the Company had substantially completed the Wind-Down of the GSE and announced that it is planning to dissolve the GSE no later than the first quarter of 2005. The Company had previously announced a target Wind-Down date of June 30, 2006.

The Privatization Act generally provides that the GSE's non-GSE affiliates cannot purchase FFELP loans as long as the GSE is acquiring such loans. On June 30, 2004, the Company purchased FFELP student loans through non-GSE affiliates and as a result, the GSE was required by statute to terminate all such activity. Going forward, the GSE will no longer be a source of liquidity for the Company's purchase of student loans and the Company's GSE related financing activities will primarily consist of refinancing the remainder of its assets through non-GSE sources, and repurchasing long-term GSE debt. All GSE debt that remains outstanding upon completion of these Wind-Down activities will be defeased through the creation of a fully collateralized trust, consisting of cash or financial instruments backed by the full faith and credit of the U.S. government with cash flows that provide for the interest and principal obligations of the defeased debt. In August 2004, the Company repurchased approximately $1.7 billion of GSE debt through a tender offer and recorded a loss of $103 million. Also in connection with the Wind-Down, the GSE will no longer issue short-term floating rate notes, but will continue to issue other short-term debt, as necessary, until all current GSE assets are refinanced. At June 30, 2004, the GSE had $10.8 billion in assets remaining of which $2.2 billion were student loans.

The Privatization Act requires that on the dissolution date, the GSE shall repurchase or redeem, or make proper provisions for repurchase or redemption of any outstanding preferred stock. The GSE redeemed its Series A, Adjustable Rate Cumulative Preferred Stock, its only outstanding preferred stock, in the fourth quarter of 2001. Also upon the GSE's dissolution, all of its remaining assets will be transferred to the Company.

Reclassifications

Certain reclassifications have been made to the balances as of and for the three and six months ended June 30, 2003 to be consistent with classifications adopted for 2004.

Reclassifications of Realized Derivative Transactions

The Financial Accounting Standards Board's (the "FASB's") Statement of Financial Accounting Standards ("SFAS") No. 133 requires net settlement income/expense on derivatives and realized gains/losses related to derivative dispositions (collectively referred to as "realized derivative transactions") that do not qualify as hedges under SFAS No. 133 to be recorded in a separate income statement line item below net interest income. The table below summarizes the reclassification of the realized derivative transactions for the three and six months ended June 30, 2003.

(Dollars in millions)	Three months ended June 30, 2003			Six months ended June 30, 2003
Reclassification of realized derivative transactions to derivative market value adjustment:
Net settlement expense on Floor Income Contracts reclassified from student loan income	$	(97	)	$	(215	)
Net settlement expense on Floor Income Contracts reclassified from servicing and securitization income		(46	)		(82	)
Net settlement income on interest rate swaps reclassified from interest expense		9			22
Net settlement expense on interest rate swaps reclassified from servicing and securitization income		(16	)		(32	)
Realized losses on closed Eurodollar futures contracts and terminated derivative contracts reclassified from other income		(25	)		(102	)

Total reclassifications to the derivative market value adjustment		(175	)		(409	)
Add: Unrealized derivative market value adjustment		(30	)		85

Derivative market value adjustment as reported	$	(205	)	$	(324	)

Recently Proposed Accounting Pronouncement

In July 2004, the Emerging Issues Task Force (the "Task Force" or the "EITF") reached a tentative conclusion on EITF Issue No. 04-8, "The Effect of Contingently Convertible Debt on Diluted Earnings per Share," ("EITF No. 04-8"), which addresses the timing of the inclusion of the dilutive effect of contingently convertible debt instruments ("Co-Cos") in diluted earnings per share. Co-Cos are generally convertible into the common shares of the issuer after the common stock share price exceeds a predetermined threshold for a specified time period, generally referred to as the market price trigger. The Task Force has proposed that the shares underlying the Co-Cos should be included in diluted earnings per share computations regardless of whether the market price trigger has been met using the "if-converted" accounting method. In the current proposal, EITF No. 04-8 would be effective

for reporting periods ending after December 15, 2004 with retroactive restatement to all required reporting periods. The Company is currently evaluating the impact of EITF No. 04-8 on its consolidated financial statements as it relates to the Company's $2 billion Co-Cos issued in May 2003.

Stock-Based Compensation

In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-Based Compensation—Transition and Disclosure" which amends SFAS No. 123, "Accounting for Stock-Based Compensation," to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, SFAS No. 148 amends the disclosure requirements of SFAS No. 123 to require more prominent disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. The additional disclosure requirements of SFAS No. 148 are effective for fiscal years ending after December 15, 2002. The Company has elected to continue to account for its employee stock options under the intrinsic value method of accounting as prescribed by Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees." Accordingly, the Company does not recognize compensation expense unless the exercise price of its employee stock options is less than the market price of the underlying stock on the date of grant. The Company grants all of its options at the fair market value of the underlying stock on the date of grant. Consequently, the Company has not recorded such expense in the periods presented.

The fair values for the options granted in the three and six months ended June 30, 2004 and 2003 were estimated at the date of grant using a Black-Scholes option pricing model, with the following weighted average assumptions:

	Three months ended June 30,		Six months ended June 30,
	2004	2003	2004	2003
Risk free interest rate	3.05%	2.26%	2.12%	2.30%
Expected volatility	16.75%	27.07%	14.15%	25.19%
Expected dividend rate	1.97%	1.03%	1.63%	1.04%
Expected life of the option (in years)	3 years	3 years	3 years	3 years

For pro forma compensation expense calculations, options that have vesting periods tied to the Company's stock price are assumed to vest ratably over the three-year historical vesting period or when the options vest, whichever occurs first.

The following table summarizes pro forma disclosures for the three and six months ended June 30, 2004 and 2003, as if the Company had accounted for employee and Board of Directors stock options granted subsequent to December 31, 1994 under the fair market value method as set forth in SFAS No. 123.

	Three months ended June 30,						Six months ended June 30,
	2004			2003			2004			2003
Net income attributable to common stock	$	612,062		$	369,819		$	900,641		$	783,493
Less: Total stock-based employee compensation expense determined under fair value based method for all awards, net of related tax effects		(6,580	)		(32,430	)		(23,078	)		(58,631	)

Pro forma net income attributable to common stock	$	605,482		$	337,389		$	877,563		$	724,862

Basic earnings per common share	$	1.39		$	..82		$	2.04		$	1.72

Pro forma basic earnings per common share	$	1.38		$	..75		$	1.99		$	1.60

Diluted earnings per common share	$	1.36		$	..80		$	2.00		$	1.68

Pro forma diluted earnings per common share	$	1.35		$	..73		$	1.96		$	1.55

The decrease in the pro forma stock-based compensation expense is due to lower stock option grants in 2003 and 2004 versus 2002 and 2001, and to lower expected volatility in the Company's common stock share price, which lowered the valuation of the 2004 stock option grants.

2. Allowance for Student Loan Losses

The provision for student loan losses represents the periodic expense of maintaining an allowance sufficient to absorb losses, net of recoveries, inherent in the student loan portfolios. The allowance for Private Credit Student Loan losses is an estimate of losses in the portfolio at the balance sheet date that will be charged off in subsequent periods. The evaluation of the provision for student loan losses is inherently subjective as it requires material estimates that may be susceptible to significant changes. The Company believes that the allowance for student loan losses is adequate to cover probable losses in the student loan portfolio.

The following table summarizes changes in the allowance for student loan losses for both the Private Credit and federally insured student loan portfolios for the three and six months ended June 30, 2004 and 2003.

		Three months ended June 30,						Six months ended June 30,
		2004			2003			2004			2003

Other			—			38			—			6,866

Balance at end of period		$	197,159		$	220,641		$	197,159		$	220,641

In addition to the provisions for student loan losses, provisions for losses on other Company loans totaled $2 million for both the three months ended June 30, 2004 and 2003, respectively, and $4 million and $2 million for the six months ended June 30, 2004 and 2003, respectively.

The table below presents the Company's Private Credit Student Loan delinquency trends as of June 30, 2004 and 2003. Delinquencies have the potential to adversely impact earnings through increased servicing and collection costs and if the delinquent accounts charge off.

⁽²⁾: Loans for borrowers who have temporarily ceased making full payments due to hardship or other factors, consistent with the established loan program servicing policies and procedures. Additionally, the forbearance balance at June 30, 2004 includes $5 million of career training loans in "closed school" status.
⁽³⁾: The delinquency period is based on the number of days scheduled payments are contractually past due.

The following table summarizes changes in the allowance for student loan losses for on-balance sheet Private Credit Student Loans for the three months and six months ended June 30, 2004 and 2003.

3. Student Loan Securitization

Securitization Activity

The Company actively securitizes its student loan assets and retains a Residual Interest, servicing rights and in some cases, reserve and other cash accounts, all of which are referred to as the Company's Retained Interest in securitized receivables.

The following table summarizes the Company's securitization activity for the three and six months ended June 30, 2004 and 2003. Those securitizations listed as sales are off-balance sheet transactions and those listed as financings remain on-balance sheet.

The conduit is a revolving 364-day facility with annual extensions. The Company may purchase loans out of this trust at its discretion, and as a result, the trust is not a qualifying special purpose entity ("QSPE") and the securitization was accounted for on-balance sheet as a Variable Interest Entity ("VIE").
⁽²⁾: In certain Consolidation Loan securitization structures, the Company holds rights that can affect the remarketing of the bonds; and as a result, these securitizations did not qualify as QSPEs. Accordingly, they are accounted for on-balance sheet as VIEs with the securitized federally insured student loans reflected in the balance sheet as "federally insured student loans in trust."

Key assumptions used in estimating the fair value of Residual Interests at the date of securitization for securitization transactions that qualified as sales during the three and six months ended June 30, 2004 and 2003 were as follows:

	Three months ended June 30,

Residual cash flows discounted at (weighted average)	12	%	—	12	%	12	%	6	%	12	%

⁽¹⁾: No Consolidation Loan securitizations in the period qualified for sale treatment.
**: 20% CPR for 2004, 15% CPR for 2005 and 6% CPR thereafter.

The following table summarizes the fair value of the Company's Retained Interests related to those securitizations that were treated as sales.

		As of June 30, 2004				As of December 31, 2003
		Fair Value		Underlying Securitized Loan Balance		Fair Value		Underlying Securitized Loan Balance
(Dollars in millions)
FFELP Stafford/PLUS loans		$	1,049	$	28,914	$	1,023	$	26,420
Consolidation Loans			654		7,766		994		8,076
Private Credit Student Loans			627		6,374		459		3,983

	Total^(1)(2)(3)	$	2,330	$	43,054	$	2,476	$	38,479

⁽¹⁾: Unrealized gains (pre-tax) included in accumulated other comprehensive income related to the Retained Interests totaled $373 million and $443 million as of June 30, 2004 and December 31, 2003, respectively.
⁽²⁾: Includes $442 million and $727 million related to the fair value of the Embedded Floor Income as of June 30, 2004 and December 31, 2003, respectively.
⁽³⁾: The Company recorded $50 million and $7 million of impairment related to the Retained Interests for the six months ended June 30, 2004 and 2003, respectively. These impairment charges are recorded as a loss and are included as a reduction to securitization revenue. The impairment charge for 2004 is primarily the result of (a) FFELP Stafford loans continuing to consolidate at levels faster than projected resulting in $17 million of impairment and (b) a decrease in value related to the Floor Income component of the Company's Retained Interest due to the significant increase in interest rates during the period resulting in $33 million of impairment. Impairment for 2003 was due to FFELP Stafford loans prepaying faster than projected.

For the Company's on-balance sheet securitizations, there were $30.7 billion and $16.1 billion of securitized student loans outstanding (face amount) as of June 30, 2004 and December 31, 2003, respectively. These student loans are reflected in the Company's balance sheet as "federally insured student loans in trust."

4. Common Stock

The closing price of the Company's common stock on June 30, 2004 was $40.45.

Earnings per Share

Basic earnings per common share ("basic EPS") are calculated using the weighted average number of shares of common stock outstanding during each period. Diluted earnings per common share ("diluted EPS") reflect the potential dilutive effect of additional common shares that are issuable upon

exercise of outstanding stock options, warrants, deferred compensation and shares held in the Employee Stock Purchase Plan ("ESPP"), determined by the treasury stock method, and equity forwards, determined by the reverse treasury stock method. Diluted EPS excludes the potential dilutive effect of senior convertible debt, as management believes conversion is not likely in the near term. However, the EITF No. 04-8 has proposed changing the accounting for Co-Cos (see Note 1, "Significant Accounting Policies—Recently Proposed Accounting Pronouncement"). The following table reflects basic and diluted EPS for the three and six months ended June 30, 2004 and 2003.

	Net Income Attributable to Common Stock		Average Shares	Earnings per Share
Three months ended June 30, 2004
Basic EPS	$	612,062	439,901	$	1.39

Diluted EPS	$	783,493	467,402	$	1.68

In July 2003, the Board of Directors voted to retire 170 million shares of common stock held in treasury, effective in September 2003. Based on an average price of $18.04 per share, this retirement

decreased the balance in treasury stock by $3.1 billion, with corresponding decreases of $34 million in common stock and $3.1 billion in retained earnings.

5. Derivative Financial Instruments

Summary of Derivative Financial Statement Impact

The following tables summarize the fair values and notional amounts or number of contracts of all derivative instruments at June 30, 2004 and December 31, 2003, and their impact on other comprehensive income and earnings for the three and six months ended June 30, 2004 and 2003. At June 30, 2004 and December 31, 2003, $102 million and $158 million (fair value), respectively, of available-for-sale investment securities and $498 million and $31 million, respectively, of cash were pledged as collateral against these derivative instruments.

6. Pension Plans

Under the Company's qualified and supplemental pension plans for eligible employees (the "Pension Plans"), participants accrue benefits under a cash balance formula. Under the formula, each participant has an account, for record keeping purposes only, to which credits are allocated each payroll period based on a percentage of the participant's compensation for the current pay period. The applicable percentage is determined by the participant's number of years of service with the Company. If an individual participated in the Company's prior pension plan as of September 30, 1999 and met certain age and service criteria, the participant ("grandfathered participant") will receive the greater of the benefits calculated under the prior plan, which uses a final average pay plan method, or the current Pension Plans under the cash balance formula.

Components of Net Periodic Pension Cost

Net periodic pension cost for the Company's Pension Plans and the Board of Directors supplemental pension plan, which was previously frozen in 1995, for the three and six months ended June 30, 2004 and 2003 included the following components:

	Three months ended June 30,						Six months ended June 30,
	2004			2003			2004			2003
Service cost—benefits earned during the period	$	3,143		$	2,775		$	6,287		$	5,551
Interest cost on project benefit obligations		2,815			2,588			5,629			5,175
Expected return on plan assets		(3,843	)		(3,208	)		(7,685	)		(6,416	)
Net amortization and deferral		(379	)		(165	)		(758	)		(330	)

Net periodic pension cost	$	1,736		$	1,990		$	3,473		$	3,980

Employer Contributions and Pension Plan Status

The Company previously disclosed in its financial statements for the year ended December 31, 2003 that it did not expect to contribute to its qualified pension plan (the "Qualified Plan") in 2004. As of June 30, 2004, the Company has made no contributions to its Qualified Plan.

Effective July 1, 2004, the Pension Plans were frozen with respect to new entrants and participants with less than five years of service. No further benefits will accrue with respect to such participants under the Pension Plans, other than interest accruals on cash balance accounts. Over the next five years, the Pension Plans will be frozen with respect to additional participants based on years of service. Employees as of June 30, 2004 who have five to nine years of service will continue to accrue benefits under the Pension Plans until June 30, 2006, while employees as of June 30, 2004 who have ten or more years of service will continue to accrue benefits under the Pension Plans through June 30, 2009. In response to this change in the Company's pension benefits, the Company increased the employer contribution in its defined contribution plan. Management believes that the net benefit from these changes in Pension Plans will mitigate projected increases in health plan costs.

7. Contingencies

The Company and various affiliates were defendants in a lawsuit brought by College Loan Corporation ("CLC") in the United States District Court for the Eastern District of Virginia alleging various breach of contract and common law tort claims in connection with CLC's consolidation loan activities. The Complaint sought compensatory damages of at least $60 million.

On June 25, 2003, after five days of trial, the jury returned a verdict in favor of the Company on all counts. CLC has since filed an appeal. Oral argument, before the U.S. Court of Appeals for the Fourth Circuit, was held on June 4, 2004. The Court of Appeals has not yet issued a decision in the case.

The Company was named as a defendant in a putative class action lawsuit brought by three Wisconsin residents on December 20, 2001 in the Superior Court for the District of Columbia. The lawsuit sought to bring a nationwide class action on behalf of all borrowers who allegedly paid "undisclosed improper and excessive" late fees over the past three years. The plaintiffs sought damages of one thousand five hundred dollars per violation plus punitive damages and claimed that the class consisted of two million borrowers. In addition, the plaintiffs alleged that the Company charged excessive interest by capitalizing interest quarterly in violation of the promissory note. On February 28, 2003, the Court granted the Company's motion to dismiss the complaint in its entirety. Oral argument was held on April 7, 2004. The Court of Appeals affirmed the Superior Court's decision granting the Company's motion to dismiss the complaint, but granted the plaintiffs leave to re-plead the first count, which alleged violations of the D.C. Consumer Protection Procedures Act. The Court of Appeals affirmed the dismissal of the remaining two counts with prejudice.

In July 2003, a borrower in California filed a class action complaint against the Company and certain of its affiliates in state court in San Francisco in connection with a monthly payment amortization error discovered by the Company in the fourth quarter of 2002. The complaint asserts claims under the California Business and Professions Code and other California statutory provisions. The complaint further seeks certain injunctive relief and restitution. On May 14, 2004, the court issued an order dismissing two of the three counts of the complaint.

The Company, together with a number of other FFELP industry participants, filed a lawsuit challenging the DOE's interpretation of and non-compliance with provisions in the HEA governing origination fees and repayment incentives on loans made under the FDLP. The lawsuit, which was filed November 3, 2000 in the United States District Court for the District of Columbia, alleges that the DOE's interpretations of and non-compliance with these statutory provisions are contrary to the statute's unambiguous text, and are arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law, and violate both the HEA and the Administrative Procedure Act. The Company together with the other plaintiffs and the DOE have filed cross-motions for summary judgment. The court has not ruled on these motions.

The Company has cooperated with the Securities and Exchange Commission (the "SEC") concerning an informal investigation that the SEC initiated on January 14, 2004. There are currently no data requests outstanding and the SEC has not sought to interview any additional witnesses. The investigation concerns certain 2003 year-end accounting entries made by employees of one of the Company's collection agency subsidiaries. The Company's Audit Committee engaged outside counsel to

investigate the matter and management conducted its own investigation. These investigations by the Audit Committee and management have been completed and the amounts in question were less than $100,000.

The Company is also subject to various claims, lawsuits and other actions that arise in the normal course of business. Most of these matters are claims by borrowers disputing the manner in which their loans have been processed. Management believes that these claims, lawsuits and other actions will not have a material adverse effect on the Company's business, financial condition or results of operations.

8. Subsequent Events

Bank One Agreement

On July 30, 2004, following the merger of JPMorgan Chase and Bank One, the Company and Bank One entered into a comprehensive agreement under which, among other things:

•: the Company agreed to the termination of its marketing services agreement with Bank One, effectively allowing Bank One to "in-source" the marketing of its own education loans;
•: Bank One pays a $14 million termination fee to the Company;
•: the Company extended its ExportSS agreement, from March 2005 through August 2008. The ExportSS agreement governs the Company's purchases of certain Bank One-branded FFELP student loans and certain Private Credit Student Loans.
•: for a $9 million fee, Bank One terminated a separate loan purchase agreement that was entered into with USA Group prior to the Company's July 2000 acquisition of that entity. Following the termination, (1) the Company retains the right to purchase FFELP loans originated under this agreement for the 2004-2005 academic year and all new loans made to existing borrowers ("serial loans") and (2) all loans that the Company originates and services on the Sallie Mae servicing platforms on behalf of Bank One will be committed for sale under the ExportSS agreement after the 2004-2005 academic year.

For the year ended 2003, marketing fees received under this arrangement were $37 million, of which, $15 million was capitalized as a reduction to student loan premiums and $22 million was recognized in other income. The Company also incurred marketing expenses of $15 million over the same period.

The Company's separate joint venture with JPMorgan Chase remains in place. Under its terms, the Company will offer JPMorgan Chase new loan purchase and servicing terms for a five-year period beginning September, 2007. If the Company and JPMorgan Chase are unable to mutually agree upon such terms by May 31, 2005, then either party may trigger a "Dutch auction" process. Under that process, the electing party offers to purchase the other party's 50 percent interest or sell its 50 percent interest in the joint venture at a specified price. The non-electing party then has the right to either sell its interest in the joint venture or purchase the electing party's interest, in either case at the originally offered price.

Acquisition of Southwest Student Services Corporation

On August 5, 2004, the Company announced that it reached agreement with the Helios Education Foundation to purchase the outstanding stock of its student loan subsidiary, Southwest Student Services Corporation ("Southwest"). The transaction includes Southwest's student loan portfolio, which as of the date of the announcement was approximately $4.5 billion, its Phoenix-based loan origination and servicing center and its sales and marketing operations.

Southwest, which was founded in 1982, provides for the origination, funding, acquisition and servicing of education loans. It is among the top 30 originators of federal student loans, issuing approximately $300 million in Stafford and PLUS loans and $1.5 billion in Consolidation Loans annually, and it is the nation's ninth largest holder of federal student loans. Southwest provides student loans and related services nationally with a primary focus on colleges and universities in Arizona and Florida. Southwest employs nearly 300 individuals.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Three and six months ended June 30, 2004 and 2003
(Dollars in millions, except per share amounts, unless otherwise stated)

OVERVIEW

We are the largest private source of funding, delivery and servicing support for education loans in the United States primarily through our participation in the FFELP. Our primary business is to originate, acquire and hold student loans. We also provide a wide range of financial services, processing capabilities and information technology to meet the needs of educational institutions, lenders, students and their families, and guarantee agencies. We earn fees for student loan servicing, guarantee processing, student loan default management and loan collections. SLM Corporation is a holding company that operates through a number of subsidiaries including the Student Loan Marketing Association, a federally chartered government-sponsored enterprise. References in this quarterly report to "the Company" refer to SLM Corporation and its subsidiaries.

Our results can be materially affected by changes in:

•: applicable laws and regulations, which may change the volume, average term, effective yields and refinancing options of student loans under the FFELP or provide advantages to competing FFELP and non-FFELP loan providers;
•: demand and competition for education financing;
•: financing preferences of students and their families;
•: borrower default rates on privately insured loans;
•: prepayment rates on student loans, particularly prepayments through loan consolidation;
•: access to the capital markets for non-GSE funding at favorable spreads; and
•: our operating execution and efficiencies, including errors, omissions, and breakdowns in internal control.

We have provided the discussion of the GSE within the context of this "Management's Discussion and Analysis of Financial Condition and Results of Operations" ("MD&A") because we have substantially completed the Wind-Down of the GSE and have ceased all operating activities such that the GSE will no longer be a source of liquidity for the Company's purchase of student loans. For the remainder of 2004, GSE activities will consist of repurchasing long-term GSE debt and preparing for the completion of the Wind-Down, now scheduled for the first quarter of 2005. All GSE debt that remains outstanding upon completion of these Wind-Down activities will be defeased through the creation of a fully collateralized trust, consisting of cash or financial instruments backed by the full faith and credit of the U.S. government with cash flows that match the interest and principal obligations of the defeased debt. At June 30, 2004, the GSE had $10.8 billion in assets remaining, of which $2.2 billion were student loans. This represents 9 percent of total Managed assets and 2 percent of Managed student loans. At June 30, 2004, the GSE's non-student loan assets primarily consisted of cash and cash equivalents and investments.

MD&A disclosures applicable solely to the GSE are included at the end of this MD&A in the section titled "STUDENT LOAN MARKETING ASSOCIATION." Discussions of Private Credit Student Loan securitizations are applicable to the Company only. The discussions of off-balance sheet loans, our fee-based businesses, and our operations on a Managed Basis, as well as the discussions set

forth below under the headings "SELECTED FINANCIAL DATA," "OTHER INCOME," "FEDERAL AND STATE TAXES" and "ALTERNATIVE PERFORMANCE MEASURES" do not involve the GSE and relate to the Company on a consolidated basis.

Through the first half of 2004, the GSE purchased the majority of our student loans and these purchases were initially financed through the issuance of short-term GSE debt obligations and then refinanced through student loan securitizations that were conducted through the GSE. Once securitized, the GSE no longer owned the student loans and the bonds issued by the trust are not obligations of the GSE. During the second quarter of 2004, the GSE originated a FFELP Stafford securitization and recorded a gain of $32 million. The Retained Interest related to that securitization, as well as all other Retained Interests in securitizations originated by the GSE that remained on the GSE's balance sheet, have been sold by the GSE to SLM Corporation. The liquidity provided to the Company by the GSE has been replaced by non-GSE financing, including securitizations originated by non-GSE subsidiaries of SLM Corporation. The GSE will no longer sponsor securitizations of student loans. (See also "LIQUIDITY AND CAPITAL RESOURCES" for further discussion of the effects of the GSE Wind-Down.)

The GSE has no employees, so the management of its operations is provided by the Company under a management services agreement. We also service the majority of the GSE's student loans under a servicing agreement between the GSE and Sallie Mae, Inc., a wholly owned, non-GSE subsidiary of SLM Corporation which includes the division of Sallie Mae Servicing.

See "STUDENT LOAN MARKETING ASSOCIATION—Privatization Act—GSE Wind-Down" for a more detailed discussion of the GSE and the progress of the Company's Wind-Down effort.

RESULTS OF OPERATIONS

NET INTEREST INCOME

Net interest income is derived largely from our portfolio of student loans that remain on-balance sheet. The "Taxable Equivalent Net Interest Income" analysis below is designed to facilitate a comparison of non-taxable asset yields to taxable yields on a similar basis. Additional information regarding the return on our student loan portfolio is set forth under "Student Loans—Student Loan Spread Analysis After Reclassification of Realized Derivative Transactions—Non-GAAP Presentation." Information regarding the provisions for losses is contained in Note 2 to the consolidated financial statements.

Taxable Equivalent Net Interest Income

The amounts in the following table are adjusted for the impact of certain tax-exempt and tax-advantaged investments based on the marginal federal corporate tax rate of 35 percent.

	Total liabilities and stockholders' equity	$	72,259			$	56,006

Net interest margin				2.02	%			2.82	%

The decrease in the net interest margin from the three and six months ended June 30, 2003 to the three and six months ended June 30, 2004 was primarily due to the decrease in Floor Income and other student loan spread related items as discussed under "Student Loans—Student Loan Spread Analysis After Reclassification of Realized Derivative Transactions—Non-GAAP Presentation." The decrease in the net interest margin was also due to the increase in lower yielding short-term investments caused by the build up of non-GSE funding in anticipation of the early completion of the GSE Wind-Down.

Reclassification of Realized Derivative Transactions—Non-GAAP Presentation

The Financial Accounting Standards Board's ("FASB's) Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging Activities," requires net settlement income/expense on derivatives and realized gains/losses on derivative dispositions ("realized derivative transactions") that do not qualify as accounting hedges under SFAS No. 133 to be recorded in a separate income statement line item below net interest income. We believe that it is also helpful to the understanding of our business to include two presentations of net interest income and net interest margin. The first is a GAAP presentation presented above that includes the net settlement income/expense on trading derivatives and realized gains/losses recorded in the derivative market value adjustment line, which excludes these items from net interest income and margin. The second is a non-GAAP presentation that reclassifies these derivative net settlements and realized gains and losses to the financial statement line item of the economically hedged item, where they are primarily included in net interest income and margin. We believe that this second presentation is meaningful as it reflects how we manage interest rate risk through the match funding of interest sensitive assets and liabilities.

The presentations of our taxable equivalent net interest income, average balance sheets, rate/volume analysis, student loan spread and funding costs in the following tables will reflect the reclassifications. The table below details the reclassification of the derivative net settlements and

realized gains/losses related to derivative dispositions that is used in the following non-GAAP presentations as discussed above.

The 58 basis point and 61 basis point differences between the three and six months ended June 30, 2004 non-GAAP net interest margins, respectively, versus the GAAP net interest margins in the same periods is primarily due to the inclusion of payments on Floor Income Contracts in the non-GAAP presentation which reduced net interest income by 59 and 65 basis points, respectively, for the three and six months ended June 30, 2004. (See "Reclassification of Realized Derivative Transactions—Non-GAAP Presentation" above.) For a discussion of other fluctuations between the three and six months ended June 30, 2004 net interest margins versus the three and six months ended June 30, 2003 net interest margins, see "Average Balance Sheets" above.

Student Loans

For both federally insured and Private Credit Student Loans, we account for premiums paid, discounts received and certain origination costs incurred on the acquisition of student loans in accordance with SFAS No. 91, "Accounting for Nonrefundable Fees and Costs Associated with Originating or Acquiring Loans and Initial Direct Costs of Leases." The unamortized portion of the premiums and discounts are included in the carrying value of the student loan on the consolidated balance sheet. We recognize income on our student loan portfolio based on the expected yield of the student loan after giving effect to the amortization of purchase premiums and the accretion of student loan discounts, as well as borrower benefit programs. Origination fees charged on Private Credit Student Loans are deferred and amortized to income over the lives of the student loans. In the "Student Loan Spread Analysis After Reclassification of Realized Derivative Transactions—Non-GAAP Presentation" table below, this amortization of origination fees is netted with the amortization of the premiums.

Student Loan Spread Analysis After Reclassification of Realized Derivative Transactions—Non-GAAP Presentation (see "Reclassification of Realized Derivative Transactions—Non-GAAP Presentation")

The following table analyzes the reported earnings from student loans both on-balance sheet and those off-balance sheet in securitization trusts. For student loans off-balance sheet, we will continue to earn securitization and servicing fee revenues over the life of the securitized loan portfolios. The off-balance sheet information presented in "LIQUIDITY AND CAPITAL RESOURCES—Securitization Activities—Servicing and Securitization Revenue" analyzes the on-going servicing revenue and Residual Interest earned on the securitized portfolios of student loans. For an analysis of our student loan spread for the entire portfolio of Managed student loans on a similar basis to the on-balance sheet analysis, see "ALTERNATIVE PERFORMANCE MEASURES—Student Loan Spread Analysis—Managed Basis."

Discussion of On-Balance Sheet Student Loan Spread, Non-GAAP Presentation

When compared with the second quarter of 2003, the decrease in the student loan spread is primarily due to lower Floor Income, higher spreads on our debt funding student loans, the increase in the average balance of Consolidation Loans as a percentage of the on-balance sheet portfolio and higher premium amortization and borrower benefit expenses. The increase in the spread to the index on our debt is due to the replacement of lower cost GSE funding with non-GSE funding in connection with the GSE Wind-Down. GSE debt generally has lower credit spreads than non-GSE funding sources and our non-GSE liabilities are significantly longer in duration than our GSE liabilities. Also, we use higher cost, longer-term debt to fund Consolidation Loans.

Consolidation Loans have lower spreads than other FFELP loans due to the 105 basis point Consolidation Loan Rebate Fee. The negative effect of this fee is partially offset by the absence of the

30 basis point Offset Fee on GSE student loans, higher SAP yield and lower student loan premium amortization discussed below. As long as interest rates remain at historically low levels and absent a program change in the next HEA reauthorization, we expect Consolidation Loans to be actively marketed by the student loan industry and remain an attractive refinancing option for borrowers, resulting in Consolidation Loans representing an increasing percentage of our federally guaranteed student loan portfolio.

The average balance of Consolidation Loans increased as a percentage of the average on-balance sheet FFELP student loan portfolio from 53 percent in the second quarter of 2003 to 57 percent in the second quarter of 2004.

The year-over-year increase in the premium amortization and borrower benefit expense is primarily the result of revised life of loan estimates for higher consolidation activity in the fourth quarter of 2003.

Floor Income

For on-balance sheet student loans, gross Floor Income is included in student loan income. The following table summarizes the components of Floor Income from on-balance sheet student loans, net of payments under Floor Income Contracts, for the three and six months ended June 30, 2004 and 2003.

	Three months ended June 30,

Net Floor Income	$	21		$	2	$	23		$	49		$	29	$	78

Net Floor Income in basis points		8			—		8			23			13		36

The decrease in Floor Income for the three months ending June 30, 2004 versus the year-ago period is primarily due to the increase in Floor Income Contracts and to the decline in Treasury bill and commercial paper rates from the July 1, 2002 reset of borrower rates to June 30, 2003. Treasury bill and commercial paper rates did not decline as steeply from the July 1, 2003 reset to June 30, 2004 as compared to the same period in 2003.

For off-balance sheet student loans, future Fixed Rate Embedded Floor Income is estimated using a discounted cash flow option pricing model and is included in the Residual Interest valuation which is initially recognized as a gain on sale. Variable Rate Embedded Floor Income is recognized as earned in servicing and securitization revenue.

The following table analyzes the ability of the FFELP student loans in our Managed student loan portfolio to earn Floor Income after June 30, 2004 and 2003. Three-month Treasury bill loans are based on the last Treasury bill auctions of June 2004 and 2003 of 1.38 percent and .90 percent, respectively. Commercial paper rate loans are based on the last commercial paper rates of 1.47 percent for June 2004 and 1.04 percent for June 2003. One-year Treasury bill loans are based on the last Treasury bill auctions of May 2004 and 2003 of 1.07 percent and 1.12 percent, respectively.

Ending balance of Private Credit Student Loans in repayment		$	2,201		$	2,403		$	2,201		$	2,403

The increase in the provision for Private Credit Student Loan losses of $2 million for the three months ending June 30, 2004 versus the year-ago period is primarily due to the increase in Private Credit Student Loans entering repayment prior to being securitized as compared to the three months ended June 30, 2003. For the three months ended June 30, 2004, Private Credit Student Loan charge-offs increased by $5 million over the comparable period in 2003, which is due to the increase in securitization activity in 2003 as we primarily securitize loans that are current, leaving a higher percentage of delinquent loans on-balance sheet, and to the increase in career training loans as a percentage of the on-balance sheet portfolio.

We charge borrower fees on the majority of Private Credit Student Loans, both at origination and when the loan enters repayment. Such fees are deferred and recognized into income as a component of interest over the life of the related pool of loans. The unamortized balance of deferred origination fee revenue at June 30, 2004 and 2003 was $168 million and $126 million, respectively.

Delinquencies

The table below presents our on-balance sheet Private Credit Student Loan delinquency trends as of June 30, 2004 and 2003. Delinquencies have the potential to adversely impact earnings through increased servicing and collection costs and if the delinquent accounts charge off.

Additionally, the forbearance balance at June 30, 2004 includes $5 million of career training loans in "closed school" status.
⁽³⁾: The delinquency period is based on the number of days scheduled payments are contractually past due.

On-Balance Sheet Funding Costs After Non-GAAP Reclassification (see "Reclassification of Realized Derivative Transactions—Non-GAAP Presentation")

Our borrowings are generally variable-rate indexed (after the effect of interest rate swaps) principally to LIBOR, the 91-day Treasury bill or the commercial paper rate. The following table summarizes the average balance of on-balance sheet debt (by index, after giving effect to the impact of interest rate swaps) for the three and six months ended June 30, 2004 and 2003.

	Three months ended June 30,								Six months ended June 30,

We continue to shift our financing from Treasury bill indexed debt to commercial paper and LIBOR indexed debt as FFELP student loans with interest rates indexed to the commercial paper rate and Private Credit Student Loans indexed to the Prime rate become a larger percentage of our portfolio. LIBOR-based debt, swapped to the daily reset LIBOR index, funds a portion of our daily reset commercial paper indexed assets, as we expect daily reset LIBOR indexed debt to remain highly correlated with daily reset commercial paper indexed assets.

OTHER INCOME

Servicing and Securitization Revenue

Servicing and securitization revenue, the ongoing revenue from securitized loan pools, which includes interest earned on the Residual Interest asset, revenue we receive for servicing the loans in the securitization trusts, and Embedded Floor Income on securitized student loans not previously included in the gain on sale calculation, is discussed in detail in "LIQUIDITY AND CAPITAL RESOURCES—Securitization Activities."

Guarantor Servicing Fees, Debt Management Fees and Other Income

The following table summarizes the components of guarantor servicing fees, debt management fees and other income for the three and six months ended June 30, 2004 and 2003.

		Three months ended June 30,				Six months ended June 30,
		2004		2003		2004		2003
Guarantor servicing and debt management fees:
	Guarantor servicing fees	$	23	$	25	$	58	$	60
	Debt management fees		70		52		150		111

	Total guarantor servicing and debt management fees	$	93	$	77	$	208	$	171

Other income:
	Late fees	$	30	$	15	$	51	$	32
	Third party servicing fees		12		13		25		28
	Gains on sales of mortgages and other loan fees		6		15		11		21
	Other		21		17		40		28

	Total other income	$	69	$	60	$	127	$	109

The $16 million and $37 million increase in guarantor servicing and debt management fees in the three and six months ended June 30, 2004, respectively, versus the year-ago periods is due to the growth in the debt management business. The $9 million and $18 million increase in other income for the three and six months ended June 30, 2004, respectively, versus the year-ago periods is mainly attributed to an accrual for late fees in the second quarter of 2004, partially offset by lower gains on sales of mortgage loans.

OPERATING EXPENSES

The following table summarizes the components of operating expenses for the three and six months ended June 30, 2004 and 2003.

	Three months ended June 30,				Six months ended June 30,
	2004		2003		2004		2003

Definite life intangible asset amortization		7		7		14		14

Total operating expenses	$	206	$	190	$	415	$	369

The increase in operating expenses for the three and six months ended June 30, 2004 versus the year-ago periods is mainly attributable to the operating expenses of Academic Management Services Corp. ("AMS") acquired in the fourth quarter of 2003, increased servicing and debt management expenses consistent with the growth in borrowers and the growth in the debt management business. Student loan servicing expenses as a percentage of the average balance of student loans serviced was .14 percent and .16 percent for the three months ended June 30, 2004 and 2003, respectively, and .15 percent and .16 percent for the six months ended June 30, 2004 and 2003, respectively.

Preferred Channel Originations

We originated $2.3 billion and $8.2 billion in student loan volume through our Preferred Channel in the three and six months ended June 30, 2004, respectively, versus $1.9 billion and $6.8 billion in the three and six months ended June 30, 2003. In both June 2004 and 2003, we delayed the processing of disbursement for Consolidated Loans to allow borrowers to take advantage of lower interest rates that took effect on July 1.

In the second quarter of 2004, we grew the Sallie Mae brand Preferred Channel Originations by 35 percent versus the year-ago quarter. As of June 30, 2004, our own brands constituted 32 percent of our Preferred Channel Originations, up from 28 percent in the year-ago period. The pipeline of loans that we currently service and are committed to purchase was $5.1 billion and $4.4 billion at June 30, 2004 and 2003, respectively. The following tables further break down our Preferred Channel

FEDERAL AND STATE TAXES

The Company is subject to federal and state income taxes, while the GSE is exempt from all state, local and District of Columbia income taxes. Our effective tax rate for the three and six months ended June 30, 2004 was 36 percent and 33 percent, respectively, versus 35 percent for both the three and six months ended June 30, 2003. The effective tax rate for the period ended June 30, 2004 reflects the permanent benefit of the exclusion of the gains on equity forward contracts under SFAS No. 150, "Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity," adopted in the third quarter of 2003. As SFAS No. 150 was implemented in the third quarter of 2003, the effective tax rate for the three and six months ended June 30, 2003 does not include any impact from equity forward contracts.

EFFECTS OF SFAS NO. 133—DERIVATIVE ACCOUNTING

SFAS No. 133 requires the Company to recognize changes in the fair value of derivative instruments currently in earnings unless specific hedge accounting criteria, as specified by SFAS No. 133, are met. We believe that our derivatives are effective economic hedges and they are a critical element of our interest rate risk management strategy. However, under SFAS No. 133, some of our derivatives, primarily Floor Income Contracts, Eurodollar futures contracts, certain basis swaps and

equity forward contracts (discussed in detail below), do not qualify for "hedge treatment" under SFAS No. 133. Consequently, the stand-alone derivative must be marked-to-market in the income statement with no consideration for the corresponding change in fair value of the hedged item. The derivative market value adjustment is primarily caused by interest rate volatility and changing credit spreads during the period and the volume and term of derivatives not receiving hedge accounting treatment.

Our Floor Income Contracts are written options. SFAS No. 133's hedge criteria regarding effectiveness when using written options is more stringent than other hedging relationships. Because the paydown of principal of the student loans underlying the Floor Income embedded in those student loans does not exactly match the change in the notional amount of our written Floor Income Contracts, the written Floor Income Contracts do not qualify as effective hedges under SFAS No. 133. The Floor Income Contracts effectively fix the amount of Floor Income we will earn over the contract period, thus eliminating the timing and uncertainty associated with Floor Income for that period. Prior to SFAS No. 133, we accounted for Floor Income Contracts as hedges and amortized the upfront cash compensation ratably over the lives of the contracts. Under SFAS No. 133, the upfront payment is deemed a liability and changes in fair value are recorded through income throughout the life of the contract. The change in the value of Floor Income Contracts is caused by changing interest rates that cause the amount of Floor Income earned on the underlying student loans and transferred to the counterparties to vary. The change in the market value of the Floor Income Contracts is economically offset by the change in value of the student loan portfolio earning Floor Income, but that offsetting change in value is not recognized under SFAS No. 133.

Basis swaps are used to convert the floating rate debt from one interest rate index to another to match the interest rate characteristics of the assets financed by that debt. We primarily use basis swaps to change the index of our fixed rate and LIBOR-based debt to better match the cash flows of our student loan assets that are primarily indexed to commercial paper or the Treasury bill. SFAS No. 133 requires that the change in the cash flows of the hedge effectively offset both the change in the cash flows of the asset and the change in the cash flows of the liability. Our basis swaps hedge variable interest rate risk and do not meet this effectiveness test because student loans can earn at either a variable or a fixed interest rate depending on market interest rates. We also have basis swaps that do not meet the SFAS No. 133 effectiveness test that economically hedge off-balance sheet instruments. As a result, these swaps are recorded at fair value with subsequent changes in value reflected in the income statement.

Generally, a decrease in current interest rates and the respective forward interest rate curves results in an unrealized loss related to our written Floor Income Contracts and Eurodollar futures contracts. Related to our basis swaps, if the two underlying indexes (and related forward curve) do not move in parallel we will experience unrealized gains/losses.

Under SFAS No. 150, equity forward contracts that allow a net settlement option either in cash or the Company's stock are required to be accounted for in accordance with SFAS No. 133 as derivatives. As a result, we now account for our equity forward contracts as stand-alone derivatives in accordance with SFAS No. 133 and mark them to market through earnings.

ALTERNATIVE PERFORMANCE MEASURES

In addition to evaluating the Company's GAAP-based financial information, management, credit rating agencies, lenders and analysts also evaluate the Company on certain non-GAAP performance measures that we refer to as "core cash" measures. While "core cash" measures are not a substitute for reported results under GAAP, we rely on "core cash" measures in operating our business because we believe they provide additional information on the operational and performance indicators that are most closely assessed by management.

We report pro forma "core cash" measures, which are the primary financial performance measures used by management not only in developing financial plans and tracking results, but also in establishing corporate performance targets and determining incentive compensation. Management believes this information provides additional insight into the financial performance of the Company's core business activities. Our "core cash" measures are not defined terms within GAAP and may not be comparable to similarly titled measures reported by other companies. "Core cash" measures reflect only current period adjustments to GAAP as described below. Accordingly, the Company's "core cash" measures presentation does not represent another comprehensive basis of accounting. A more detailed discussion of the differences between GAAP and "core cash" measures follows.

1): Securitization: Under GAAP, certain securitization transactions are accounted for as sales of assets. Under "core cash," we present all securitization transactions as long-term non-recourse financings. The upfront "gains on sale from securitization" as well as ongoing "servicing and securitization revenue" presented in accordance with GAAP are excluded from "core cash" and replaced by the interest income, provision for loan losses, and interest expense as they are earned or incurred on the securitized loans.
: The following table summarizes "core cash" securitization adjustments for the three and six months ended June 30, 2004 and 2003.

	Three months ended June 30,						Six months ended June 30,
	2004			2003			2004			2003
"Core cash" securitization adjustments:
Net interest income on securitized loans, after provisions for losses	$	251		$	266		$	513		$	496
Gains on student loan securitizations		(198	)		(314	)		(312	)		(620	)
Servicing and securitization revenue		(124	)		(200	)		(261	)		(389	)

Total "core cash" securitization adjustments	$	(71	)	$	(248	)	$	(60	)	$	(513	)

2): Derivative Accounting: "Core cash" measures exclude the periodic unrealized gains and losses caused by the one-sided mark-to-market derivative valuations prescribed by SFAS No. 133 and recognize the economic effect of these hedges, which results in recognition of any cash paid or received being recognized ratably as an expense or revenue over the hedged item's life. The effects of derivatives hedging Floor Income is discussed below under Floor Income. See also "EFFECTS OF SFAS NO. 133—DERIVATIVE ACCOUNTING" for a more detailed discussion.
: The table below separates the effect of the unrealized derivative marks-to-market included in the derivative market value adjustment under SFAS No. 133 from the non-Floor Income realized derivative transactions for the three and six months ended June 30, 2004 and 2003, respectively, in

accordance with the accounting principles employed in all years prior to the SFAS No. 133 implementation.

3): Floor Income: The timing and amount (if any) of Floor Income earned is uncertain and in excess of expected spreads and, therefore, we exclude such income from "core cash" measures when it is not economically hedged from "core cash" measures.
: We employ derivatives, primarily Floor Income Contracts and Eurodollar futures contracts, to economically hedge Floor Income. As discussed under "EFFECTS OF SFAS NO. 133—DERIVATIVE ACCOUNTING," these derivatives do not qualify as effective accounting hedges and therefore are marked-to-market through the derivative market value adjustment. For "core cash" measures, we reverse the fair value adjustments on the Floor Income Contracts and include the amortization of net premiums received (net of Eurodollar futures contracts' realized gains or losses) in income. Since we exclude Floor Income that is not economically hedged, we also exclude net settlements on derivative contracts, primary payments on Floor Income Contracts, and certain gains and losses on derivatives and financial instruments that were economically hedging Floor Income. The following table summarizes the Floor Income adjustments for the three and six months ended June 30, 2004 and 2003.

	Three months ended June 30,						Six months ended June 30,

Student Loan Spread Analysis—Managed Basis

The following table analyzes the earnings from our portfolio of Managed student loans on a "core cash" basis. This analysis includes both on-balance sheet and off-balance sheet loans in securitization trusts and derivatives economically hedging these line items (see "NET INTEREST INCOME—Reclassification of Realized Derivative Transactions—Non-GAAP Presentation") and excludes Floor Income while including the amortization of upfront payments on Floor Income Contracts.

Discussion of Managed Student Loan Spread

The decrease in the second quarter of 2004 Managed student loan spread versus the second quarter of 2003 is primarily due to higher spreads on our debt funding student loans and the increase in the average balance of Consolidation Loans as a percentage of the Managed portfolio. The increase in the spread to the index on our debt is due to the replacement of lower cost GSE funding with non-GSE funding in connection with the GSE Wind-Down. GSE debt generally has lower credit spreads than non-GSE funding sources and our non-GSE liabilities are significantly longer in duration than our GSE liabilities. Also, we use higher cost, longer-term debt to fund Consolidation Loans.

Consolidation Loans have lower spreads than other FFELP loans due to the 105 basis point Consolidation Loan Rebate Fee. The negative effect of this fee is partially offset by the absence of the

30 basis point Offset Fee on GSE student loans, higher SAP yield and lower student loan premium amortization. As long as interest rates remain at historically low levels and absent a program change in the next HEA reauthorization, we expect Consolidation Loans to be actively marketed by the student loan industry and remain an attractive refinancing option for borrowers, resulting in Consolidation Loans representing an increasing percentage of our federally guaranteed student loan portfolio.

The 2004 student loan spread was positively impacted by the increase in the average balance of Managed Private Credit Student Loans as a percentage of the average Managed student loan portfolio from 9 percent in the second quarter 2003 to 11 percent in the second quarter 2004. Private Credit Student Loans are subject to credit risk and therefore earn higher spreads which averaged 4.72 percent in the second quarter of 2004 for the Managed Private Credit Student Loan portfolio versus a spread of 1.57 percent for the Managed guaranteed student loan portfolio. The second quarter Managed Student Loan spread also benefited from higher amortization of upfront premiums received on Floor Income Contracts.

Allowance for Private Credit Student Loan Losses—Managed Basis

An analysis of our allowance for loan losses for Managed Private Credit Student Loans for the three and six months ended June 30, 2004 and 2003 is presented in the following table.

Ending balance of Managed Private Credit Student Loans in repayment		$	4,792		$	3,629		$	4,792		$	3,629

The increase in the provision for Managed Private Credit Student Loans for the second quarter of 2004 versus the year-ago quarter is primarily attributed to the revision of our default assumptions in the fourth quarter of 2003 and growth in the portfolio.

Delinquencies—Managed Basis

The table below presents our Private Credit Student Loan delinquency trends as of June 30, 2004 and 2003 on a Managed Basis. Delinquencies have the potential to adversely impact earnings through increased servicing and collection costs and if the delinquent accounts charge off.

Loans in forbearance status increased from 10 percent of loans in repayment and forbearance status at June 30, 2003 to 11 percent of loans in repayment and forbearance status at June 30, 2004. The increase over the year-ago period is associated with several small Private Credit Student Loan programs. The forbearance ratios at June 30, 2004 for all of the primary programs (Signature, LAW, MBA, etc.) are the same or lower than the year-ago period.

⁽²⁾: Loans for borrowers who have temporarily ceased making full payments due to hardship or other factors, consistent with the established loan program servicing procedures and policies. Additionally, the forbearance balance at June 30, 2004 included $5 million of career training loans in "closed school" status.
⁽³⁾: The delinquency period is based on the number of days scheduled payments are contractually past due.

LIQUIDITY AND CAPITAL RESOURCES

We depend on the debt capital markets to support our business plan and we have developed deep and diverse funding sources to ensure continued access to the capital markets as we complete our transition from GSE funding to SLM Corporation non-GSE funding. Our biggest funding challenge going forward is to maintain cost effective liquidity to fund the growth in the Managed portfolio of student loans as well as refinancing previously securitized loans when consolidated back on-balance sheet. At the same time we must maintain earnings spreads and control interest rate risk to preserve earnings growth. The main source of non-GSE funding is student loan securitizations. In the first half of 2004, we securitized $22.7 billion in student loans in nine transactions versus $13.1 billion in eight transactions in the first half of 2003. Securitizations now comprise approximately 67 percent of total Managed debt at June 30, 2004. We expect approximately 75 percent of our student loan funding to come through securitizations by 2006. Our securitizations backed by FFELP loans are unique securities in the asset-backed class as they are backed by student loans with an explicit guarantee on 98 percent of principal and interest. This guarantee is subject to service compliance but is not related to the Company's GSE subsidiary. As evidenced by the 2004 volume, we have built a highly liquid and deep market for student loan securitizations by broadening our investor base worldwide. At June 30, 2004, we financed 98 percent of our Managed student loans from non-GSE sources versus 64 percent at June 30, 2003. In addition to securitizations, in the first half of 2004 we also significantly increased and diversified other non-GSE financing through the issuance of $9.9 billion in SLM Corporation, term, unsecured non-GSE debt. In total, at June 30, 2004, non-GSE on-balance sheet debt, exclusive of on-balance sheet securitizations, totaled $30.7 billion, a 115 percent increase over June 30, 2003.

Another major objective when financing our business is to minimize interest rate risk through match funding of our assets and liabilities. Generally, on a pooled basis to the extent practicable, we match the interest rate and reset characteristics of our Managed assets and liabilities. In this process, we use derivative financial instruments extensively to reduce our interest rate and foreign currency exposure. This interest rate risk management helps us to achieve a stable student loan spread irrespective of the interest rate environment. (See also "Interest Rate Risk Management" below.)

The following tables present the ending balances at June 30, 2004 and 2003 and average balances and average interest rates of our Managed borrowings for the three and six months ended June 30, 2004 and 2003. The average interest rates include derivatives that are economically hedging the underlying debt, but do not qualify for hedge accounting treatment under SFAS No. 133. (See "NET

SLM Corporation's stand-alone liquidity is derived from our asset-backed commercial paper program, the issuance of unsecured commercial paper, $3 billion in committed bank lines of credit, and short-term investment portfolio, due mainly to broad market acceptance of our principal asset of government guaranteed student loans.

During the second quarter of 2004, we launched our first asset-backed commercial paper conduit. This is a major new source of short-term liquidity for the Company, as we can borrow up to $5 billion under this structure.

GSE Financing Activities

As of June 30, 2004, we have substantially completed the Wind-Down of the GSE. The GSE will no longer finance the purchase of student loans and will have minimal debt issuances through the completion of the Wind-Down, now scheduled no later than the first quarter of 2005. In August 2004, the Company repurchased approximately $1.7 billion of GSE debt through a tender offer and recorded a loss of $103 million. Any GSE debt securities not tendered must be defeased under the terms of the Privatization Act in an irrevocable defeasance trust that is collateralized by cash, U.S. Treasury securities and agency securities that are backed by the full faith and credit of the U.S. government. Based on interest rates of August 6, 2004, management estimates additional losses to defease the debt securities that were not tendered to be between $108 million and $118 million. Management expects to defease any GSE debt that is remaining outstanding after the tender offer no later than the first quarter of 2005. (See also "STUDENT LOAN MARKETING ASSOCIATION—Privatization Act—GSE Wind-Down.")

Securitization Activities

Securitization Program

Our FFELP Stafford, Private Credit Student Loan and certain Consolidation Loan securitizations are structured such that they meet the sale criteria of SFAS No. 140, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities—a Replacement of SFAS No. 125," by using a two-step transaction with a qualifying special purpose entity ("QSPE") that legally isolates the transferred assets from the Company, even in the event of bankruptcy, and are accounted for off-balance sheet as a sale. The holders of the beneficial interests issued by the QSPE are not constrained from pledging or exchanging their interests and we do not maintain effective control over the transferred assets. In all of our off-balance sheet securitizations, we retain the right to receive the cash flows from the securitized student loans in excess of cash flows required to pay interest and principal on the bonds issued by the trust and servicing and administration fees.

Prior to 2003, all of our securitization structures were off-balance sheet transactions. In certain 2003 and 2004 Consolidation Loan securitization structures, we hold rights that can affect the remarketing of the bonds, which are not significantly limited in nature, and as a result, these securitizations did not qualify as QSPEs. Accordingly, they are accounted for on-balance sheet as variable interest entities ("VIEs") with the securitized federally insured student loans reflected in the balance sheet as "federally insured student loans in trust." These securitization structures were developed to broaden and diversify the investor base for Consolidation Loan securitizations by allowing us to issue bonds with non-amortizing, fixed rate and foreign currency denominated tranches.

⁽¹⁾: In the second quarter of 2004, the Company closed its first asset-backed commercial paper conduit. The conduit is a multi-seller conduit that allows the Company to borrow up to $5 billion. The conduit is a revolving 364-day facility with annual extensions. The Company may purchase loans out of this trust at its discretion and as a result, the trust is not a QSPE and the securitization was accounted for on-balance sheet as a VIE).
⁽²⁾: In certain Consolidation Loan securitization structures, the Company holds rights that can affect the remarketing of the bonds; and as a result, these securitizations did not qualify as QSPEs. Accordingly, they are accounted for on-balance sheet as VIEs with the securitized federally insured student loans reflected in the balance sheet as "federally insured student loans in trust."

The increase in the Private Credit Student Loans securitization gain percentage in 2004 is due to the underlying student loans having higher spreads and the related bonds having a lower funding cost due primarily to the maturing of the Private Credit Student Loan marketplace which has resulted in greater acceptance by investors and lower spreads on the debt issued.

At June 30, 2004 and December 31, 2003, securitized student loans outstanding totaled $74.4 billion and $55.1 billion, respectively. In 2004, we expect to issue between $25.0 billion and

$27.5 billion of term asset-backed securities with our asset-backed commercial paper program adding another $5 billion.

Liquidity Risk

Except for minor short-term debt issuances by the GSE in connection with the Wind-Down, all of our future financing activity will come from non-GSE sources, and as a result, our long-term funding, credit spreads and liquidity exposure to the capital markets have shifted from the government agency capital markets to the corporate and asset-backed capital markets. A major disruption in the fixed income capital markets that limits our ability to raise funds or significantly increases the cost of those funds could have a material impact on our ability to acquire student loans or on our results of operations. Going forward, securitizations will continue to be the primary source of long-term financing. Except for our asset-backed commercial paper conduit, our securitizations are structured such that we do not provide any level of financial, credit or liquidity support to any of the trusts. Our exposure is limited to the recovery of the Retained Interest asset on the balance sheet related to our off-balance sheet deals. Our FFELP Stafford Retained Interests are subject to prepayment risk primarily from consolidating loans that could materially impair their value. Our FFELP securitizations have minimal credit and interest rate risk and as a result, outside of the prepayment risk, we believe that, even in times of great stress in the capital markets, the likelihood is remote that any of these off-balance sheet arrangements could be impaired to the point at which they could result in a material adverse impact on the Company.

Retained Interest on Securitized Loans

The Residual Interest plus any reserve or cash accounts constitute the Retained Interest asset on-balance sheet. The Retained Interests are recorded at fair value at the time of sale and each subsequent quarter using a discounted cash flow methodology. At June 30, 2004 and December 31, 2003, the fair value of the Retained Interest was $2.3 billion and $2.5 billion, respectively. The average balance of the Retained Interest for the three months ended June 30, 2004 and 2003 was $2.5 billion and $2.7 billion, respectively, and for the six months ended June 30, 2004 and 2003 was $2.5 billion and $2.4 billion, respectively. The deferred tax liability associated with these assets was $254 million and $275 million at June 30, 2004 and December 31, 2003, respectively.

Embedded Fixed Rate Floor Income

Included in the gain on student loan securitizations of Consolidation Loans is an estimate of the Embedded Fixed Rate Floor Income from the loans securitized. Depending on interest rate levels, the ongoing re-evaluation of this estimate of Embedded Fixed Rate Floor Income can cause volatility in the fair value of the Retained Interest asset. The fair value of the Embedded Fixed Rate Floor Income included in the Retained Interest asset as of June 30, 2004 and December 31, 2003 was $442 million and $727 million, respectively.

Servicing and Securitization Revenue

The following table summarizes the components of servicing and securitization revenue for the three and six months ended June 30, 2004 and 2003.

		Three months ended June 30,						Six months ended June 30,
		2004			2003			2004			2003
Servicing revenue		$	78		$	77		$	154		$	152
Securitization revenue, exclusive of Embedded Floor Income			23			54			53			104

Servicing and securitization revenue, before Embedded Floor Income			101			131			207			256

Embedded Floor Income			66			109			144			194
	Less: Floor Income previously recognized in gain calculation		(43	)		(40	)		(90	)		(61	)

Net Embedded Floor Income			23			69			54			133

Total servicing and securitization revenue		$	124		$	200		$	261		$	389

Average off-balance sheet student loans		$	39,318		$	37,811		$	38,552		$	36,527

Average balance of Retained Interest		$	2,468		$	2,695		$	2,455		$	2,446

Servicing and securitization revenue as a percentage of the average balance of off-balance sheet student loans (annualized)			1.27	%		2.12	%		1.36	%		2.15	%

Fluctuations in servicing and securitization revenue are generally driven by the amount of and the difference in the timing of Floor Income recognition on off-balance sheet student loans, as well as the impact of Consolidation Loan activity on FFELP Stafford student loan securitizations. Consolidation of FFELP Stafford loans are prepayments in FFELP Stafford trusts and higher than forecasted levels of consolidation activity can result in an impairment of the Residual Interest asset and negatively impact yields used to recognize subsequent income. We recorded $50 million and $7 million of impairment related to the Retained Interests for the six months ended June 30, 2004 and 2003, respectively. These impairment charges are recorded as a loss and are included as a reduction in securitization revenue. The impairment charge for 2004 is primarily the result of (a) FFELP Stafford loans continuing to consolidate at levels faster than projected, resulting in $17 million of impairment and (b) rising interest rates which decreased the value of the Floor Income component of our Retained Interest resulting in $33 million of impairment. Impairment for 2003 was due to FFELP Stafford loans prepaying faster than projected. We receive annual servicing fees of 90 basis points, 50 basis points and 70 basis points of the outstanding securitized loan balance related to our Stafford, Consolidation Loan and Private Credit Student Loan securitizations, respectively.

Interest Rate Risk Management

Interest Rate Gap Analysis

We manage our interest rate risk on a Managed Basis. As a result, we use on and off-balance sheet derivatives to hedge the basis, interest rate and foreign currency risk in our securitization trusts as the trusts typically issue asset-backed securities with a variety of interest rate terms and in multiple currencies to fund student loans indexed to either the 91-day Treasury bill, commercial paper or in the case of Private Credit Student Loans, the Prime rate.

In the table below, the Company's variable rate assets and liabilities are categorized by reset date of the underlying index. Fixed rate assets and liabilities are categorized based on their maturity dates. An interest rate gap is the difference between volumes of assets and volumes of liabilities maturing or repricing during specific future time intervals. The following gap analysis reflects rate-sensitive positions at June 30, 2004 and is not necessarily reflective of positions that existed throughout the period.

	(in millions)
2006	18.0	$33.82 – $41.88	$	37.47
2007	13.4	37.70 – 41.09		38.69
2008	8.7	38.35 – 40.56		39.28
2009	7.1	37.89 – 38.58		38.18

	47.2		$	38.26

At June 30, 2004, the total common shares that could potentially be acquired over the next five years under outstanding equity forward contracts was 47.2 million shares at an average price of $38.26 per share. We have remaining authority to enter into additional share repurchases and equity forward contracts for 20.7 million shares.

In July 2003, the Board of Directors voted to retire 170 million shares of common stock held in treasury, effective in September 2003. Based on an average price of $18.04 per share, this retirement decreased the balance in treasury stock by $3.1 billion, with corresponding decreases of $34 million in common stock and $3.1 billion in retained earnings.

STUDENT LOAN MARKETING ASSOCIATION

Privatization Act—GSE Wind-Down

The Privatization Act generally provides that the GSE's non-GSE affiliates cannot purchase FFELP loans as long as the GSE is acquiring such loans. On June 30, 2004, the Company purchased FFELP student loans through non-GSE affiliates and as a result the GSE was required by statute to terminate all such activity. Going forward, the GSE will no longer be a source of liquidity for the Company's purchase of student loans and the Company's GSE-related financing activities will primarily consist of refinancing the remainder of its assets through non-GSE sources, and repurchasing long-term GSE debt. All GSE debt that remains outstanding upon completion of these Wind-Down activities will be defeased through creation of a fully collateralized trust, consisting of cash or financial instruments backed by the full faith and credit of the U.S. government with cash flows that provide for the interest and principal obligations of the defeased debt. In August of the 2004, the Company repurchased approximately $1.7 billion of GSE debt through a tender offer and recorded a loss of $103 million. Based on current interest rates on August 6, 2004 the Company estimates that additional losses related to future debt repurchases and the eventual defeasance of the debt will be between $108 million and $118 million.

The Privatization Act requires that the GSE maintain a minimum statutory capital adequacy ratio (the ratio of the GSE's stockholders' equity to total assets plus 50 percent of the credit equivalent

amount of certain off-balance sheet items) of at least 2.25 percent or be subject to certain "safety and soundness" requirements designed to restore compliance. While the GSE may not finance or guarantee the activities of its non-GSE affiliates, it may, subject to its minimum capital requirements, dividend retained earnings and surplus capital to SLM Corporation, which in turn may contribute such amounts to its non-GSE subsidiaries. At June 30, 2004, the GSE's statutory capital adequacy ratio was 16.03 percent.

The GSE has also received guidance from the U.S. Department of the Treasury's Office of Sallie Mae Oversight ("OSMO") regarding safety and soundness considerations affecting its Wind-Down. As a result, in connection with any dividend declarations, the GSE will supplement the statutory minimum capital ratio requirement with a risk-based capital measurement formula. At June 30, 2004, the GSE's capital ratio under this measurement formula was 63.60 percent, which was above OSMO's minimum recommended level of 4.00 percent. Management does not expect the capital levels of our consolidated balance sheet to change as a result of this supplemental formula.

The Privatization Act imposes certain restrictions on intercompany relations between the GSE and its affiliates during the Wind-Down Period. The GSE may, however, continue to issue new debt obligations maturing on or before September 30, 2008 although, because of the accelerated Wind-Down described above, we are limiting the maturity on any new GSE debt to six months. The GSE has not issued any long-term debt since July 2003 and in June 2004, we announced that the GSE will no longer issue short-term floating rate notes, but will continue to issue other short-term debt as necessary, until all current GSE assets are refinanced. The legislation further provides that the legal status and attributes of the GSE's debt obligations, including the exemptions from Securities and Exchange Commission registration and state taxes, will be fully preserved until their respective maturities. Such debt obligations will remain GSE debt obligations, whether such obligations were outstanding at the time of, or issued subsequent to, the reorganization of the GSE into the current holding company structure.

In connection with the Wind-Down of the GSE, we have securitized, sold, and transferred the majority of the GSE's assets such that at June 30, 2004, the GSE had $10.8 billion in assets remaining of which $2.2 billion were student loans. This represents 9 percent of total Managed assets and 2 percent of Managed student loans. At June 30, 2004, the GSE's non-student loan assets primarily consisted of cash and cash equivalents and investments. For loans securitized by the GSE, the GSE retains an interest in the loans, which is recognized on the balance sheet as "Retained Interest in securitized receivables." In connection with the GSE Wind-Down, the GSE sold all of its Retained Interests to a non-GSE subsidiary of the Company.

Given the GSE's current exemption from state income taxes, management is continually evaluating the impact upon the Company's overall state tax position resulting from planned sales and transfers of GSE assets. It is currently projected that for 2005, the Company's state tax rate will increase by 0.5 percent to 1 percent above current levels as a result of the GSE asset transfers.

The following table summarizes the GSE's asset sales and transfers for the three and six months ended June 30, 2004 and 2003 (carrying value includes accrued interest).

RECENT DEVELOPMENTS

Bank One Agreement

On July 30, 2004, following the merger of JPMorgan Chase and Bank One, the Company and Bank One entered into a comprehensive agreement under which, among other things:

•: we agreed to the termination of our marketing services agreement with Bank One, effectively allowing Bank One to "in-source" the marketing of its own education loans;
•: Bank One pays a $14 million termination fee to the Company;
•: our ExportSS agreement, through which we purchase certain Bank One-branded FFELP student loans and certain Private Credit Student Loans is extended from March 2005 through August 2008;
•: for a $9 million fee, Bank One terminated a separate loan purchase agreement that was entered into with USA Group prior to our July 2000 acquisition of that entity. Following the termination, (1) we retain the right to purchase FFELP loans originated under this agreement for the 2004-2005 academic year and all serial loans and (2) all loans that we originate and service on the our servicing platforms on behalf of Bank One will be committed for sale under the ExportSS agreement after the 2004-2005 academic year.

Under the marketing agreement, in 2003 we recognized marketing expenses of approximately $15 million. At the same time, we had approximately $37 million in marketing fees, of which approximately $22 million was recognized in other income and $15 million was capitalized as a reduction in loan purchase premium. We believe we can offset this lost income as well as an expected gradual reduction in loan purchase volume from Bank One with increased Private Credit and FFELP loan originations through our more profitable internal brands.

Our separate joint venture with JPMorgan Chase remains in place. Under its terms, we will offer JPMorgan Chase new loan purchase and servicing terms for a five-year period beginning September, 2007. If the Company and JPMorgan Chase are unable to mutually agree upon such terms by May 31, 2005, then either party may trigger a "Dutch auction" process. Under that process, the electing party offers to purchase the other party's 50 percent interest or sell its 50 percent interest in the joint venture at a specified price. The non-electing party then has the right to either sell its interest in the joint venture or purchase the electing party's interest, in either case at the originally offered price. If we are the successful purchaser in a Dutch auction, then for a two-year period following the closing:

•: JPMorgan Chase may not compete with the Company in the marketing, purchasing, servicing or ownership of education loans (except with respect to the continuation of business activities under the Bank One name or the name of any other entity with which JPMorgan Chase affiliates),
•: we may use certain Chase trademarks for a nominal annual fee, and
•: we acquire all rights to make additional FFELP student loans (serial loans) to customers of the joint venture.

If JPMorgan Chase is the successful purchaser in a Dutch auction, then for a two-year period following the closing:

•: it may use certain Sallie Mae trademarks for a nominal annual fee (but the Company would not be constrained by any non-compete restriction), and
•: we would be required to act as origination and servicing agent for JPMorgan Chase at market rates.

Acquisition of Southwest Student Services Corporation

OTHER RELATED EVENTS AND INFORMATION

Congress reauthorizes the Higher Education Act ("HEA") every five years. The HEA was originally scheduled to expire on September 30, 2003, but by its terms was automatically extended to September 30, 2004. We now expect that Congress will actively debate provisions of the HEA that govern the FFELP and the FDLP during 2004 and final action on the next reauthorization may not occur until 2005 (following another short extension of the current Act).

As with past HEA reauthorizations, there are many legislative proposals being advanced by schools, industry participants and other interested stakeholders. Sallie Mae has joined the "Coalition for Better Student Loans," a group of organizations representing colleges, universities, financial aid administrators, parents and other loan providers that has advanced a series of proposals designed to strengthen federal student loan programs, including:

•: lowering the cost of borrowing by eliminating origination fees paid by needy students,
•: raising Stafford loan limits to permit schools to offer students more federal student loans with their below-market interest rates and student-friendly repayment terms,
•: making it easier for students to repay their loans by offering more flexible repayment options,
•: maintaining a viable loan consolidation program, and
•: extending loan forgiveness to borrowers who work in certain highly needed occupations.

The President's budget also contains proposals to increase first-year loan limits, expand extended repayment options for FFELP borrowers, mandate a one percent guaranty fee for borrowers, and phase out higher special allowance payments associated with certain tax-exempt student loan bonds. Other proposals have already been announced by Presidential hopefuls or introduced by Members of Congress, including proposals to provide financial incentives to schools to join the FDLP, repeal the "single holder rule," permit borrowers who already completed their higher education studies to refinance or reconsolidate previously consolidated loans, require lenders to win student loan contracts by bidding at an auction and eliminate floor income on variable rate student loans. Under the single holder rule, if only one lender holds all of a borrower's loans, then another lender cannot consolidate the loans away from the current holder unless the current holder declines to consolidate loans for the borrower or is unwilling to offer income-sensitive repayment terms. If the single holder rule is repealed, the Company's student loan portfolio could be subject to an increased level of consolidation activity. In addition, if the reconsolidation proposal is enacted, the Company could experience a significant increase in refinancing activity, which, in turn, would have a material adverse effect on the Company's financial condition and results of operations. If adopted, a student loan auction proposal, depending on its structure, could have a material adverse effect on the Company's student loan spread. Finally, enactment of the proposal to eliminate Floor Income would decrease the Company's interest income in certain interest rate environments.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Sensitivity Analysis

The effect of short-term movements in interest rates on our results of operations and financial position has been limited through our interest rate risk management. The following tables summarize the effect on earnings for the three and six months ended June 30, 2004 and 2003 and the effect on fair values at June 30, 2004 and December 31, 2003, based upon a sensitivity analysis performed by us assuming a hypothetical increase in market interest rates of 100 basis points and 300 basis points while funding spreads remain constant. We have chosen to illustrate the effects of a hypothetical increase in interest rates, as an increase gives rise to a larger absolute value change to the financial statements. The effect on earnings was performed on our variable rate assets, liabilities and hedging instruments while the effect on fair values was performed on our fixed rate assets, liabilities and hedging instruments.

A primary objective in our funding is to minimize our sensitivity to changing interest rates by generally funding our floating rate student loan portfolio with floating rate debt. However, as discussed under "Student Loans—On-Balance Sheet Floor Income," in the current low interest rate environment, we can have a fixed versus floating mismatch in funding as the student loan earns at the fixed borrower rate and the funding remains floating. Therefore, absent other hedges, in a low interest rate environment, the hypothetical rise in interest rates in the above table has a greater adverse effect on earnings and fair values due to the reduction in potential Floor Income than in higher interest rate environments where the interest rate formula rises above the borrower rate and the student loans become a floating rate asset that is matched with floating rate debt.

During the three and six months ended June 30, 2004, certain FFELP student loans were earning Floor Income and we locked-in a portion of that Floor Income through the use of futures and Floor Income Contracts. The result of these hedging transactions was to convert a portion of the fixed rate nature of student loans to variable rate, and to fix the relative spread between the student loan asset rate and the variable rate liability.

In the above table under the scenario where interest rates increase 100 basis points, the increase in pre-tax net income before the unrealized derivative market value adjustment for 2004 is primarily due to the impact of (i) our off-balance sheet Consolidation Loan securitizations and the related Embedded Floor Income recognized as part of the gain on sale, which results in no change in the Embedded Floor Income as a result of the increase in rates and (ii) our unhedged on-balance sheet loans not currently having significant Floor Income due to the recent increase in interest rates, which results in these loans being more variable rate in nature. The decrease in pre-tax net income in 2003 before the unrealized derivative market value adjustment reflects lower Floor Income on the unhedged portion of our student loan portfolio. Under the scenario where interest rates increase 300 basis points, the change in pre-tax net income before the unrealized derivative market value adjustment is not proportional to the change under the scenario where interest rates increase 100 basis points because of the additional spread earned on loans hedged with futures and swaps mentioned above and the greater proportion of loans earning at a floating rate under a 300 basis point increase in rates.

Item 4. Controls and Procedures

The Company carried out an evaluation, as required by the Securities Exchange Act of 1934 (the "Exchange Act") Rule 13a-15(b), under the supervision and with the participation of the Company's management, including the Company's Chief Executive Officer, Executive Vice President, Finance and Executive Vice President, Accounting and Risk Management, of the effectiveness of the design and operation of the Company's disclosure controls and procedures as of the end of the period covered by this report.

Disclosure controls and procedures include internal controls and other procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act, such as this Annual Report, is properly recorded, processed, summarized and reported within the time periods required by the Securities and Exchange Commission's (the "SEC's") rules and forms. Management does not expect that its disclosure controls and procedures will prevent all errors and fraud. A control system, irrespective of how well it is designed and operated, can only provide reasonable assurance—and cannot guarantee—that it will succeed in its stated objectives.

We monitor our disclosure controls and procedures and our internal controls and make modifications as necessary. By monitoring our control systems, we intend that they be maintained as dynamic systems that change as conditions warrant. The evaluation of our disclosure controls and procedures as of the end of the period covered by this report is performed on a quarterly basis so that the conclusions of management (including the Chief Executive Officer, Executive Vice President, Finance and Executive Vice President, Accounting and Risk Management) concerning controls effectiveness can be reported in our Quarterly Reports on Form 10-Q and Annual Reports on Form 10-K. In addition, our disclosure controls and procedures are evaluated on an ongoing basis by our internal auditors, by our Corporate Finance and Corporate Accounting Departments. As a result of such ongoing evaluations, we periodically make changes to our disclosure controls and procedures to improve the quality of our financial statements and related disclosures. Since the date of the last evaluation, we have taken, and continue to take, steps to improve the design and operation of our internal controls.

Based upon their evaluation, the Chief Executive Officer, Executive Vice President, Finance and Executive Vice President, Accounting and Risk Management, concluded that, as of the end of the period covered by this report, our disclosure controls and procedures are effective in timely alerting them to material information and in providing reasonable assurance that our financial statements are fairly presented in conformity with generally accepted accounting principles. In addition, during the period covered by this quarterly report, there have been no changes to our internal controls over financial reporting that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

The Company was named as a defendant in a putative class action lawsuit brought by three Wisconsin residents on December 20, 2001 in the Superior Court for the District of Columbia. The lawsuit sought to bring a nationwide class action on behalf of all borrowers who allegedly paid "undisclosed improper and excessive" late fees over the past three years. The plaintiffs sought damages of one thousand five hundred dollars per violation plus punitive damages and claimed that the class consisted of two million borrowers. In addition, the plaintiffs alleged that the Company charged excessive interest by capitalizing interest quarterly in violation of the promissory note. On February 28, 2003, the Court granted the Company's motion to dismiss the complaint in its entirety. Oral argument was held on April 7, 2004. The Court of Appeals affirmed the Superior Court's decision granting our motion to dismiss the complaint, but granted plaintiffs leave to re-plead the first count, which alleged violations of the D.C. Consumer Protection Procedures Act. The Court of Appeals affirmed the dismissal of the remaining two counts with prejudice.

The Company, together with a number of other FFELP industry participants, filed a lawsuit challenging the DOE's interpretation of and non-compliance with provisions in the HEA governing origination fees and repayment incentives on loans made under the FDLP. The lawsuit, which was filed November 3, 2000 in the United States District Court for the District of Columbia, alleges that the Department's interpretations of and non-compliance with these statutory provisions are contrary to the statute's unambiguous text, and are arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law, and violate both the HEA and the Administrative Procedure Act. The Company together with the other plaintiffs and the DOE have filed cross-motions for summary judgment. The Court has not ruled on these motions.

The Company has cooperated with the SEC concerning an informal investigation that the SEC initiated on January 14, 2004. There are currently no data requests outstanding and the SEC has not sought to interview any additional witnesses. The investigation concerns certain 2003 year-end accounting entries made by employees of one of the Company's debt collection agency subsidiaries. The Company's Audit Committee engaged outside counsel to investigate the matter and management conducted its own investigation. These investigations by the Audit Committee and management have been completed and the amounts in question were less than $100,000.

We are also subject to various claims, lawsuits and other actions that arise in the normal course of business. Most of these matters are claims by borrowers disputing the manner in which their loans have

been processed. Management believes that these claims, lawsuits and other actions will not have a material adverse effect on our business, financial condition or results of operations.

Item 2. Changes in Securities, Use of Proceeds and Issuer Purchases of Equity Securities

STUDENT LOAN MARKETING ASSOCIATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Information at June 30, 2004 and for the three and six months ended
June 30, 2004 and 2003 is unaudited)
(Dollars in thousands, unless otherwise stated)

1. Significant Accounting Policies

Basis of Presentation

The accompanying unaudited consolidated financial statements of the Student Loan Marketing Association ("SLMA" or the "GSE") have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP in the United States of America for complete consolidated financial statements. In the opinion of management, all adjustments considered necessary for a fair statement have been included. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Operating results for the three and six months ended June 30, 2004 may not necessarily be indicative of the results for the year ending December 31, 2004. These unaudited financial statements should be read in conjunction with the audited financial statements and related notes included in the Company's 2003 Annual Report on Form 10-K.

Going Concern—GSE Wind-Down

The financial statements have been prepared using the going concern basis of accounting, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company continues to use going concern accounting as substantially all assets and operations of the GSE will be transferred to its parent, SLM Corporation. Under the Privatization Act, the GSE must wind down its operations and dissolve on or before September 30, 2008. As of June 2004, the Company had substantially completed the Wind-Down of the GSE and announced that it is planning to dissolve the GSE no later than the first quarter of 2005. Accordingly, SLMA will not continue as a going concern and its assets will be realized and liabilities satisfied through the Wind-Down process. SLM Corporation had previously announced a target Wind-Down date of June 30, 2006.

The Privatization Act generally provides that the GSE's non-GSE affiliates cannot purchase FFELP loans as long as the GSE is acquiring such loans. On June 30, 2004, SLM Corporation purchased FFELP student loans through non-GSE affiliates and as a result the GSE was required by statute to terminate all such activity. Going forward, the GSE will no longer be a source of liquidity for SLM Corporation's purchase of student loans and SLM Corporation's GSE related financing activities will primarily consist of refinancing the remainder of the GSE's assets through non-GSE sources, and repurchasing long-term GSE debt. All GSE debt that remains outstanding upon completion of these Wind-Down activities will be defeased through the creation of a fully collateralized trust, consisting of cash or financial instruments backed by the full faith and credit of the U.S. government with cash flows that match the interest and principal obligations of the defeased debt. In August 2004, SLM Corporation repurchased approximately $1.7 billion of GSE debt through a tender offer and recorded a loss of $103 million. Also in connection with the Wind-Down, the GSE will no longer issue short-term floating rate notes, but will continue to issue other short-term debt, as necessary, until all current GSE assets are refinanced. At June 30, 2004, the GSE had $10.8 billion in assets remaining of which $2.2 billion were student loans.

The Privatization Act requires that on the dissolution date, the GSE shall repurchase or redeem, or make proper provisions for repurchase or redemption of any outstanding preferred stock. The GSE

redeemed its Series A, Adjustable Rate Cumulative Preferred Stock, its only outstanding preferred stock, in the fourth quarter of 2001. Also upon the dissolution, all of its remaining assets will be transferred to SLM Corporation.

2. Student Loans

SLMA purchases student loans from originating lenders. SLMA's portfolio consists principally of loans originated under two federally sponsored programs—the Federal Family Education Loan Program ("FFELP") and the Health Education Assistance Loan Program ("HEAL"). SLMA also purchases Private Credit Student Loans.

The following table reflects the distribution of SLMA's student loan portfolio by program as of June 30, 2004 and 2003.

	June 30,
	2004			2003

Allowance for loan losses		(2	)		(53	)

Total student loans, net	$	2,228		$	31,250

⁽¹⁾: The HEAL program was integrated into the FFELP in 1998, so there are no new originations under that program.

3. Allowance for Student Loan Losses

The provision for loan losses represents the periodic expense of maintaining an allowance sufficient to absorb losses, net of recoveries, inherent in the student loan portfolios. The allowance for Private Credit Student Loan losses is an estimate of losses in the portfolio at the balance sheet date that will be charged off in subsequent periods. The evaluation of the provision for loan losses is inherently subjective as it requires material estimates that may be susceptible to significant changes. SLMA believes that the allowance for loan losses is adequate to cover probable losses in the student loan portfolio.

The following table summarizes changes in the allowance for student loan losses for SLMA's Private Credit and federally insured student loan portfolios for the three and six months ended June 30, 2004 and 2003.

		Three months ended June 30,						Six months ended June 30,
		2004			2003			2004			2003

Deductions
	Reductions for student loan sales and securitizations		(18,370	)		(62,443	)		(36,657	)		(82,737	)
	Charge-offs		(223	)		(3,567	)		(4,662	)		(7,214	)

Balance at end of period		$	2,473		$	52,655		$	2,473		$	52,655

SLMA receives certain fees related to originated loans at both origination and the commencement of repayment. These origination fees are charged to cover, in part, anticipated loan losses. Such fees are deferred and recognized into income as a component of interest over the average life of the related pool of loans.

4. Student Loan Securitization

When SLMA sold student loans in securitizations prior to September 30, 2003, it retained a Residual Interest and, in some cases, a cash reserve account, all of which are Retained Interests in the securitized receivables. In 2003, and in the second quarter of 2004, SLMA sold its Retained Interests in securitizations to SLM Corporation in a cash transaction.

A-10

The following table summarizes securitization activity for the three and six months ended June 30, 2004 and 2003. Those securitizations listed as sales are off-balance sheet transactions and those listed as financings remain on-balance sheet.

Total securitizations	6	$	17,156					6	$	10,829

⁽¹⁾: In the second quarter of 2004, SLMA closed its first asset-backed commercial paper conduit. The conduit is a multi-seller conduit that allows SLMA to borrow up to $5 billion. The conduit is a revolving 364-day facility with annual extensions. SLMA may purchase loans out of this trust at its discretion. As a result, the trust did not qualify as a qualifying special purpose entity ("QSPE") and the securitization was accounted for on-balance sheet as a Variable Interest Entity ("VIE").
⁽²⁾: In certain Consolidation Loan securitization structures, SLMA holds rights that can affect the remarketing of the bonds; and as a result, these securitizations did not qualify as QSPEs. Accordingly, they are accounted for on-balance sheet as VIEs with the securitized federally insured student loans reflected in the balance sheet as "federally insured student loans in trust."

A-11

Key economic assumptions used in estimating the fair value of the Retained Interests at the date of securitization related to those securitization transactions that qualify as sales during the three and six months ended June 30, 2004 and 2003 were as follows:

	Three months ended June 30,
	2004			2003
	FFELP Stafford		Consolidation⁽¹⁾	FFELP Stafford		Consolidation
Prepayment speed	**		—	9	%	7	%

Residual cash flows discounted at (weighted average)	12	%	—	12	%	6	%

⁽¹⁾: No Consolidation Loan securitizations in the period qualified for sale treatment.
**: 20% CPR for 2004, 15% CPR for 2005 and 6% CPR thereafter.

SLMA is a member of a group of affiliated companies and has significant transactions with members of the group. Accordingly, the terms of such transactions may not necessarily be indicative of transactions amongst wholly unrelated companies.

In connection with the Wind-Down of the GSE, SLM Corporation has securitized, sold and transferred the majority of SLMA's assets. The following table summarizes SLMA's asset sales and transfers for the three and six months ended June 30, 2004 and 2003 (carrying value includes accrued interest).

⁽¹⁾: These VIEs consist of securitized Consolidation Loans totaling $2.4 billion and $2.3 billion for the three months ended June 30, 2004 and 2003, respectively, and $10.5 billion and $4.3 billion for the six months ended June 30, 2004 and 2003, respectively, and the sales are recorded net of debt issued. Included in the $10.5 billion of loans sold in 2004 were $2.2 billion of Consolidation Loans acquired by SLMA from SLM Education Loan Corporation, a non-GSE subsidiary of the Company.
⁽²⁾: The student loans were sold by SLMA to a subsidiary of SLM Corporation at fair market value.
⁽³⁾: This dividend was recorded at fair market value.
⁽⁴⁾: SLMA sold basis swaps and floor contracts to SLM Corporation at fair market value.
⁽⁵⁾: SLMA sold its Retained Interests in securitized receivables to a subsidiary of SLM Corporation at fair market value.
⁽⁶⁾: SLMA sold its subsidiaries to SLM Corporation in connection with the GSE Wind-Down. This consisted primarily of $5.1 billion in student loans and $1.2 billion in short-term and long-term debt.

As described above, such transactions were among a group of related parties. Such transactions were conducted at estimated market value, which was determined using discounted cash flow models and other estimation techniques. Different assumptions or changes in future market conditions could significantly affect the estimates of fair value.

In connection with the transfer of employees from SLMA to SLM Corporation and its non-GSE subsidiaries, SLMA and SLM Corporation and various of its non-GSE subsidiaries entered into

A-16

Management Services Agreements ("MSAs") whereby all management and administrative support would be provided to SLMA for a monthly fee. Intercompany expenses under the MSAs for the three months ended June 30, 2004 and 2003 totaled $16 million and $26 million, respectively and for the six months ended June 30, 2004 and 2003 totaled $33 million and $47 million, respectively. Effective January 1, 2003, only third party loan acquisition costs are being booked directly to SLMA and are included in other operating expenses.

Intercompany expenses under the servicing contract between SLMA and Sallie Mae, Inc., a wholly owned non-GSE subsidiary of SLM Corporation which includes the division of Sallie Mae Servicing, for the three months ended June 30, 2004 and 2003 totaled $24 million and $39 million, respectively and for the six months ended June 30, 2004 and 2003 totaled $62 million and $84 million, respectively.

At June 30, 2004 and December 31, 2003, SLMA had a net intercompany receivable of $49 million and a net intercompany liability of $530 million, respectively, with SLM Corporation and several of its non-GSE subsidiaries. The net receivable at June 30, 2004 primarily related to the sale of student loans and other assets to a subsidiary of SLM Corporation. This receivable was settled in early July 2004. Exclusive of the intercompany asset sales, the GSE had a net payable incurred in the normal course of business, exclusive of the intercompany promissory note owed to Hemar Insurance Corporation of America ("HICA") discussed below.

SLMA purchases insurance for its Private Credit Student Loan portfolio from HICA. SLMA pays HICA insurance premiums in return for HICA's guarantee of payment of principal and interest on Private Credit Student Loans. In connection with this arrangement, HICA invests its insurance reserves related to SLMA's HICA insured loans in a Master Promissory Note of SLMA to HICA. In addition to the intercompany balances between SLMA and SLM Corporation, at June 30, 2004 and December 31, 2003, SLMA owed HICA $69 million under this note at the end of each period.

7. Contingencies

SLMA and various affiliates were defendants in a lawsuit brought by College Loan Corporation ("CLC") in the United States District Court for the Eastern District of Virginia alleging various breach of contract and common law tort claims in connection with CLC's consolidation loan activities. The Complaint sought compensatory damages of at least $60 million.

On June 25, 2003, after five days of trial, the jury returned a verdict in favor of SLMA on all counts. CLC has since filed an appeal. Oral argument, before the U.S. Court of Appeals for the Fourth Circuit, was held on June 4, 2004. The Court of Appeals has not yet issued a decision in the case.

SLMA was named as a defendant in a putative class action lawsuit brought by three Wisconsin residents on December 20, 2001 in the Superior Court for the District of Columbia. The lawsuit sought to bring a nationwide class action on behalf of all borrowers who allegedly paid "undisclosed improper and excessive" late fees over the past three years. The plaintiffs sought damages of one thousand five hundred dollars per violation plus punitive damages and claimed that the class consisted of two million borrowers. In addition, the plaintiffs alleged that SLMA charged excessive interest by capitalizing interest quarterly in violation of the promissory note. On February 28, 2003, the Court granted SLMA's

A-17

motion to dismiss the complaint in its entirety. Oral argument was held on April 7, 2004. The Court of Appeals affirmed the Superior Court's decision granting SLMA's motion to dismiss the complaint, but granted plaintiffs leave to re-plead the first count, which alleged violations of the D.C. Consumer Protection Procedures Act. The Court of Appeals affirmed the dismissal of the remaining two counts with prejudice.

In July 2003, a borrower in California filed a class action complaint against SLMA and certain of its affiliates in state court in San Francisco in connection with a monthly payment amortization error discovered by SLMA in the fourth quarter of 2002. The complaint asserts claims under the California Business and Professions Code and other California statutory provisions. The complaint further seeks certain injunctive relief and restitution. On May 14, 2004, the court issued an order dismissing two of the three counts of the complaint.

SLMA, together with a number of other FFELP industry participants, filed a lawsuit challenging the DOE's interpretation of and non-compliance with provisions in the HEA governing origination fees and repayment incentives on loans made under the FDLP. The lawsuit, which was filed November 3, 2000 in the United States District Court for the District of Columbia, alleges that the DOE's interpretations of and non-compliance with these statutory provisions are contrary to the statute's unambiguous text, and are arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law, and violate both the HEA and the Administrative Procedure Act. SLMA together with the other plaintiffs and the DOE have filed cross-motions for summary judgment. The Court has not ruled on these motions.

SLMA is also subject to various claims, lawsuits and other actions that arise in the normal course of business. Most of these matters are claims by borrowers disputing the manner in which their loans have been processed. Management believes that these claims, lawsuits and other actions will not have a material adverse effect on SLMA's business, financial condition or results of operations.
