Organization and Business

1.	Organization and Business

SLM Corporation (“we,” “us,” “our,” or the “Company”) is a holding company that operates through a number of subsidiaries. We were formed in 1972 as the Student Loan Marketing Association, a federally chartered government-sponsored enterprise (the “GSE”), with the goal of furthering access to higher education by acting as a secondary market for federal student loans. In 2004, we completed our transformation to a private company through our wind-down of the GSE. The GSE’s outstanding obligations were placed into a Master Defeasance Trust Agreement as of December 29, 2004, which was fully collateralized by direct, noncallable obligations of the United States.

Currently, our primary business is to originate, service and collect loans we make to students and their families to finance the cost of their education. Since July 2010, we have originated only Private Education Loans. We use “Private Education Loans” to mean education loans to students or their families that are non-federal loans and loans not insured or guaranteed under the previously existing Federal Family Education Loan Program (“FFELP”). The core of our marketing strategy is to generate student loan originations by promoting our products on campus through the financial aid office and through direct marketing to students and their families. Since the beginning of 2006, virtually all of our Private Education Loans have been originated and funded by Sallie Mae Bank, a Utah industrial bank subsidiary, which is regulated by the Utah Department of Financial Institutions (“UDFI”) and the Federal Deposit Insurance Corporation (“FDIC”). We also provide servicing, loan default aversion and defaulted loan collection services for loans owned by other institutions, including the U.S. Department of Education (“ED”). We also operate Upromise, Inc. (“Upromise”), a consumer savings network that provides financial rewards on everyday purchases to help families save for college, and provide insurance products through Sallie Mae Insurance Services to protect their college investment through tuition, rental and life insurance services.

In addition, we are currently the largest holder, servicer and collector of loans made under the previously existing FFELP, and the majority of our income has been derived, directly or indirectly, from our portfolio of FFELP Loans and servicing we have provided for FFELP Loans. In 2010, Congress passed legislation ending the origination of education loans under FFELP. The terms and conditions of existing FFELP Loans were not affected by this legislation. Our FFELP Loan portfolio will amortize over approximately 20 years. The fee income we have earned from providing servicing and contingent collection services on such loans will similarly decline over time.

On May 29, 2013, we announced our intent to separate into two distinct publicly-traded entities — an education loan management business (“NewCo”) and a consumer banking business (“SLM BankCo”). It is our intent to effect the separation through the distribution of the common stock of NewCo, which was formed to hold the assets and liabilities associated with our education loan management business. In order to effect the separation, we will first undergo an internal corporate reorganization, which is necessary for the contemplated separation of NewCo from our consumer banking business. This internal corporate reorganization will be then followed by a pro rata share distribution of all of the shares of NewCo common stock to our stockholders that will implement the actual separation of NewCo. Throughout our Annual Report on Form 10-K, we sometimes collectively refer to the proposed internal corporate reorganization and separation as the “Spin-Off.”

Significant Accounting Policies

2.	Significant Accounting Policies

Use of Estimates

Our financial reporting and accounting policies conform to generally accepted accounting principles in the United States of America (“GAAP”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Current market conditions increase the risk and complexity of the judgments in these estimates and actual results could differ from estimates. Key accounting policies that include significant judgments and estimates include the allowance for loan losses, the effective interest rate method (amortization of student loan and debt premiums and discounts), fair value measurements, goodwill and acquired intangible asset impairment assessments, and derivative accounting.

Consolidation

The consolidated financial statements include the accounts of SLM Corporation and its majority-owned and controlled subsidiaries and those Variable Interest Entities (“VIEs”) for which we are the primary beneficiary, after eliminating the effects of intercompany accounts and transactions.

We consolidate any VIEs where we have determined we are the primary beneficiary. The primary beneficiary is the entity which has both: (1) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (2) the obligation to absorb losses or receive benefits of the entity that could potentially be significant to the VIE, except as described in the next paragraph. As it relates to our securitized assets as of December 31, 2013, we are the servicer of the securitized assets and own the Residual Interest of the securitization trusts. As a result, we are the primary beneficiary of our securitization trusts and consolidate those trusts.

In 2013, we sold Residual Interests in FFELP Loan securitization trusts to third parties. We will continue to service the student loans in the trusts under existing agreements. Prior to the sale of the Residual Interests, we had consolidated the trusts as VIEs because we had met the two criteria for consolidation. We had determined we were the primary beneficiary because (1) as servicer to the trust we had the power to direct the activities of the VIE that most significantly affected its economic performance and (2) as the residual holder of the trust, we had an obligation to absorb losses or receive benefits of the trust that could potentially be significant. Upon the sale of the Residual Interests we were no longer the residual holder, thus we determined we no longer met criterion (2) above and deconsolidated the trusts. As a result of these transactions, we removed securitization trust assets of $12.5 billion and the related liabilities of $12.1 billion from the balance sheet and recorded a $312 million gain as part of “gains on sales of loans and investments” in 2013.

Fair Value Measurement

We use estimates of fair value in applying various accounting standards for our financial statements. Fair value measurements are used in one of four ways:

•

In the consolidated balance sheet with changes in fair value recorded in the consolidated statement of income;

•

In the consolidated balance sheet with changes in fair value recorded in the accumulated other comprehensive income section of the consolidated statement of changes in stockholders’ equity;

•

In the consolidated balance sheet for instruments carried at lower of cost or fair value with impairment charges recorded in the consolidated statement of income; and

•

In the notes to the financial statements.

Fair value is defined as the price to sell an asset or transfer a liability in an orderly transaction between willing and able market participants. In general, our policy in estimating fair value is to first look at observable market prices for identical assets and liabilities in active markets, where available. When these are not available, other inputs are used to model fair value such as prices of similar instruments, yield curves, volatilities, prepayment speeds, default rates and credit spreads (including for our liabilities), relying first on observable data from active markets. Depending on current market conditions, additional adjustments to fair value may be based on factors such as liquidity, credit, and bid/offer spreads. Transaction costs are not included in the determination of fair value. When possible, we seek to validate the model’s output to market transactions. Depending on the availability of observable inputs and prices, different valuation models could produce materially different fair value estimates. The values presented may not represent future fair values and may not be realizable.

We categorize our fair value estimates based on a hierarchical framework associated with three levels of price transparency utilized in measuring financial instruments at fair value. Classification is based on the lowest level of input that is significant to the fair value of the instrument. The three levels are as follows:

•

Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access at the measurement date. The types of financial instruments included in level 1 are highly liquid instruments with quoted prices.

•

Level 2 — Inputs from active markets, other than quoted prices for identical instruments, are used to determine fair value. Significant inputs are directly observable from active markets for substantially the full term of the asset or liability being valued.

•

Level 3 — Pricing inputs significant to the valuation are unobservable. Inputs are developed based on the best information available. However, significant judgment is required by us in developing the inputs.

Loans

Loans, consisting primarily of federally insured student loans and Private Education Loans, that we have the ability and intent to hold for the foreseeable future are classified as held-for-investment and are carried at amortized cost. Amortized cost includes the unamortized premiums, discounts, and capitalized origination costs and fees, all of which are amortized to interest income as further discussed below. Loans which are held-for-investment also have an allowance for loan loss as needed. Any loans we have not classified as held-for-investment are classified as held-for-sale, and carried at the lower of cost or fair value. Loans are classified as held-for-sale when we have the intent and ability to sell such loans. Loans which are held-for-sale do not have the associated premium, discount, and capitalized origination costs and fees amortized into interest income. In addition, once a loan is classified as held-for-sale, there is no further adjustment to the loan’s allowance for loan losses that existed immediately prior to the reclassification to held-for-sale.

As market conditions permit, we may securitize loans as a source of financing for those loans. If we elect to use a securitization program to finance loans, loans are selected based on the required characteristics to structure the desired transaction at the most favorable financing terms (e.g., type of loan, mix of interim vs. repayment status, credit rating and maturity dates). Due to some of the structuring terms, certain transactions may qualify for sale treatment while others do not qualify for sale treatment and are recorded as financings. All of our student loans are initially categorized as held-for-investment until there is certainty as to each specific loan’s ultimate financing because we do not securitize all loans and currently all of our securitizations do not qualify for sale treatment. It is only when we have selected the loans to securitize and that securitization transaction qualifies as a sale do we transfer the loans into the held-for-sale classification and carry them at the lower of cost or fair value. If we anticipate recognizing a gain related to the impending securitization, then the fair value of the loans is higher than their respective cost basis and no valuation allowance is recorded.

Student Loan Income

For loans classified as held-for-investment, we recognize student loan interest income as earned, adjusted for the amortization of premiums and capitalized direct origination costs, accretion of discounts, and Repayment Borrower Benefits. These adjustments result in income being recognized based upon the expected yield of the loan over its life after giving effect to prepayments and extensions, and to estimates related to Repayment Borrower Benefits. The estimate of the prepayment speed includes the effect of consolidations, voluntary prepayments and student loan defaults, all of which shorten the life-of-loan. Prepayment speed estimates also consider the utilization of deferment, forbearance and extended repayment plans which lengthen the life-of-loan. For Repayment Borrower Benefits, the estimates of their effect on student loan yield are based on analyses of historical payment behavior of customers who are eligible for the incentives and its effect on the ultimate qualification rate for these incentives. We regularly evaluate the assumptions used to estimate the prepayment speeds and the qualification rates used for Repayment Borrower Benefits. In instances where there are changes to the assumptions, amortization is adjusted on a cumulative basis to reflect the change since the acquisition of the loan. We also pay an annual 105 basis point Consolidation Loan Rebate Fee on FFELP Consolidation Loans which is netted against student loan interest income. Additionally, interest earned on student loans reflects potential non-payment adjustments in accordance with our uncollectible interest recognition policy as discussed further in “Allowance for Loan Losses” of this Note 2. We do not amortize any premiums, discounts or other adjustments to the basis of student loans when they are classified as held-for-sale.

Allowance for Loan Losses

We consider a loan to be impaired when, based on current information, a loss has been incurred and it is probable that we will not receive all contractual amounts due. When making our assessment as to whether a loan is impaired, we also take into account more than insignificant delays in payment. We generally evaluate impaired loans on an aggregate basis by grouping similar loans. Impaired loans also include those loans which are individually assessed and measured for impairment at a loan level, such as in a troubled debt restructuring (“TDR”). We maintain an allowance for loan losses at an amount sufficient to absorb losses incurred in our portfolios at the reporting date based on a projection of estimated probable credit losses incurred in the portfolio.

In determining the allowance for loan losses on our non-TDR portfolio, we estimate the principal amount of loans that will default over the next two years (two years being the expected period between a loss event and default) and how much we expect to recover over time related to the defaulted amount. Expected defaults less our expected recoveries equal the allowance related to this portfolio. Our historical experience indicates that, on average, the time between the date that a customer experiences a default causing event (i.e., the loss trigger event) and the date that we charge off the unrecoverable portion of that loan is two years. Separately, for our TDR portfolio, we estimate an allowance amount sufficient to cover life-of-loan expected losses through an impairment calculation based on the difference between the loan’s basis and the present value of expected future cash flows (which would include life-of-loan default and recovery assumptions) discounted at the loan’s original effective interest rate (see “Allowance for Private Education Loan Losses” to this Note 2). The separate allowance estimates for our TDR and non-TDR portfolios, are combined into our total Allowance for Private Education Loan losses.

In estimating both the non-TDR and TDR allowance amounts, we start with historical experience of customer default behavior. We make judgments about which historical period to start with and then make further judgments about whether that historical experience is representative of future expectations and whether additional adjustments may be needed to those historical default rates. We also take the economic environment into consideration when calculating the allowance for loan losses. We analyze key economic statistics and the effect we expect it to have on future defaults. Key economic statistics analyzed as part of the allowance for loan losses are unemployment rates and other asset type delinquency rates. More judgment has been required over the last several years, compared with years prior, in light of the recent downturn in the U.S. economy and high levels of unemployment and its effect on our customer’s ability to pay their obligations.

Our allowance for loan losses is estimated using an analysis of delinquent and current accounts. Our model is used to estimate the likelihood that a loan receivable may progress through the various delinquency stages and ultimately charge off. The evaluation of the allowance for loan losses is inherently subjective, as it requires material estimates that may be susceptible to significant changes. The estimate for the allowance for loan losses is subject to a number of assumptions. If actual future performance in delinquency, charge-offs and recoveries are significantly different than estimated, this could materially affect our estimate of the allowance for loan losses and the related provision for loan losses on our income statement.

Below we describe in further detail our policies and procedures for the allowance for loan losses as they relate to our Private Education Loan and FFELP Loan portfolios.

Allowance for Private Education Loan Losses

We determine the collectability of our Private Education Loan portfolio by evaluating certain risk characteristics. We consider school type, credit score (FICO), existence of a cosigner, loan status and loan seasoning as the key credit quality indicators because they have the most significant effect on our determination of the adequacy of our allowance for loan losses. The type of school customers attend can have an impact on their job prospects after graduation and therefore affects their ability to make payments. Credit scores are an indicator of the creditworthiness of a customer and generally the higher the credit score the more likely it is the customer will be able to make all of their contractual payments. Loan status affects the credit risk because generally a past due loan is more likely to result in a credit loss than an up-to-date loan. Additionally, loans in a deferred payment status have different credit risk profiles compared with those in current pay status. Loan seasoning affects credit risk because a loan with a history of making payments generally has a lower incidence of default than a loan with a history of making infrequent or no payments. The existence of a cosigner lowers the likelihood of default. We monitor and update these credit quality indicators in the analysis of the adequacy of our allowance for loan losses on a quarterly basis.

To estimate the probable credit losses incurred in the loan portfolio at the reporting date, we use historical experience of customer payment behavior in connection with the key credit quality indicators and incorporate management expectation regarding macroeconomic and collection procedure factors. Our model is based upon the most recent 12 months of actual collection experience, seasonally adjusted, as the starting point and applies expected macroeconomic changes and collection procedure changes to estimate expected losses caused by loss events incurred as of the balance sheet date. Our model places a greater emphasis on the more recent default experience rather than the default experience for older historical periods, as we believe the recent default experience is more indicative of the probable losses incurred in the loan portfolio today. Similar to estimating defaults, we use historical customer payment behavior to estimate the timing and amount of future recoveries on charged-off loans. We use judgment in determining whether historical performance is representative of what we expect to collect in the future. We then apply the default and collection rate projections to each category of loans. Once the quantitative calculation is performed, we review the adequacy of the allowance for loan losses and determine if qualitative adjustments need to be considered. Additionally, we consider changes in laws and regulations that could potentially impact the allowance for loan losses. More judgment has been required over the last several years, compared with years prior, in light of the U.S. economy and its effect on our customer’s ability to pay their obligations. We believe that our model reflects recent customer behavior, loan performance, and collection performance, as well as expectations about economic factors.

Similar to the rules governing FFELP payment requirements, our collection policies allow for periods of nonpayment for customers requesting additional payment grace periods upon leaving school or experiencing temporary difficulty meeting payment obligations. This is referred to as forbearance status and is considered separately in our allowance for loan losses. The loss confirmation period is in alignment with our typical collection cycle and takes into account these periods of nonpayment.

On July 1, 2011, we adopted new guidance that clarified when a loan restructuring constitutes a TDR. In applying the new guidance we determined that certain Private Education Loans for which we grant forbearance of greater than three months should be classified as TDRs. If a loan meets the criteria for troubled debt accounting then an allowance for loan losses is established which represents the present value of the losses that are expected to occur over the remaining life of the loan. This accounting results in a higher allowance for loan losses than our previously established allowance for these loans as our previous allowance for these loans represented an estimate of charge-offs expected to occur over the next two years (two years being our loss confirmation period). The new accounting guidance was effective as of July 1, 2011 but was required to be applied retrospectively to January 1, 2011. This resulted in $124 million of additional provision for loan losses in the third quarter of 2011 from approximately $3.8 billion of student loans being classified as TDRs. This new accounting guidance is only applied to certain customers who use their fourth or greater month of forbearance since the time period this new guidance is effective. This new accounting guidance has the effect of accelerating the recognition of expected losses related to our Private Education Loan portfolio. The increase in the provision for losses as a result of this new accounting guidance does not reflect a decrease in credit expectations of the portfolio or an increase in the expected life-of-loan losses related to this portfolio. We believe forbearance is an accepted and effective collection and risk management tool for Private Education Loans. We plan to continue to use forbearance and as a result, we expect to have additional loans classified as TDRs in the future (see “Note 4 — Allowance for Loan Losses” for a further discussion on the use of forbearance as a collection tool).

As part of concluding on the adequacy of the allowance for loan losses, we review key allowance and loan metrics. The most relevant of these metrics considered are the allowance coverage of charge-offs ratio; the allowance as a percentage of total loans and of loans in repayment; and delinquency and forbearance percentages.

Certain Private Education Loans do not require customers to begin repayment until six months after they have graduated or otherwise left school. Consequently, our loss estimates for these programs are generally low while the customer is in school. At December 31, 2013, 17 percent of the principal balance in the higher education Private Education Loan portfolio was related to customers who are in an in-school/grace/deferment status and not required to make payments. As this population of customers leaves school, they will be required to begin payments on their loans, and the allowance for loan losses may change accordingly.

We consider a loan to be delinquent 31 days after the last payment was contractually due. We use a model to estimate the amount of uncollectible accrued interest on Private Education Loans and reserve for that amount against current period interest income.

In general, Private Education Loan principal is charged off against the allowance when at the end of the month the loan exceeds 212 days past due. The charged-off amount equals the estimated loss of the defaulted loan balance. Actual recoveries, as they are received, are applied against the remaining loan balance that was not charged off. If periodic recoveries are less than originally expected, the difference results in immediate additional provision expense and charge-off of such amount.

Our allowance for Private Education Loan losses also provides for possible additional future charge-offs related to the receivable for partially charged-off Private Education Loans. At the end of each month, for loans that are 212 days past due, we charge off the estimated loss of a defaulted loan balance. Actual recoveries are applied against the remaining loan balance that was not charged off. We refer to this remaining loan balance as the “receivable for partially charged-off loans.” If actual periodic recoveries are less than expected, the difference is immediately charged off through the allowance for loan losses with an offsetting reduction in the receivable for partially charged-off Private Education Loans. If actual periodic recoveries are greater than expected, they will be reflected as a recovery through the allowance for Private Education Loan losses once the cumulative recovery amount exceeds the cumulative amount originally expected to be recovered. Private Education Loans which defaulted between 2008 and 2013 for which we have previously charged off estimated losses have, to varying degrees, not met our post-default recovery expectations to date and may continue not to do so. According to our policy, we have been charging off these periodic shortfalls in expected recoveries against our allowance for Private Education Loan losses and the related receivable for partially charged-off Private Education Loans and we will continue to do so.

Allowance for FFELP Loan Losses

FFELP Loans are insured as to their principal and accrued interest in the event of default subject to a Risk Sharing level based on the date of loan disbursement. These insurance obligations are supported by contractual rights against the United States. For loans disbursed after October 1, 1993, and before July 1, 2006, we receive 98 percent reimbursement on all qualifying default claims. For loans disbursed on or after July 1, 2006, we receive 97 percent reimbursement. For loans disbursed prior to October 1, 1993, we receive 100 percent reimbursement.

Similar to the allowance for Private Education Loan losses, the allowance for FFELP Loan losses uses historical experience of customer default behavior and a two-year loss confirmation period to estimate the credit losses incurred in the loan portfolio at the reporting date. We apply the default rate projections, net of applicable Risk Sharing, to each category for the current period to perform our quantitative calculation. Once the quantitative calculation is performed, we review the adequacy of the allowance for loan losses and determine if qualitative adjustments need to be considered.

Cash and Cash Equivalents

Cash and cash equivalents includes term federal funds, Eurodollar deposits, commercial paper, asset-backed commercial paper, treasuries, money market funds and bank deposits with original terms to maturity of less than three months.

Restricted Cash and Investments

Restricted cash primarily includes amounts held in student loan securitization trusts and other secured borrowings. This cash must be used to make payments related to trust obligations. Amounts on deposit in these accounts are primarily the result of timing differences between when principal and interest is collected on the trust assets and when principal and interest is paid on trust liabilities.

Securities pledged as collateral related to our derivative portfolio, where the counterparty has rights to replace the securities, are classified as restricted. When the counterparty does not have these rights, the security is recorded in investments and disclosed as pledged collateral in the notes. Additionally, certain counterparties require cash collateral pledged to us to be segregated and held in restricted cash accounts.

Investments

Our available-for-sale investment portfolio consists of investments that are AAA equivalent securities and are carried at fair value, with the temporary changes in fair value carried as a separate component of stockholders’ equity, net of taxes. The amortized cost of debt securities in this category is adjusted for amortization of premiums and accretion of discounts, which are amortized using the effective interest rate method. Other-than-temporary impairment is evaluated by considering several factors, including the length of time and extent to which the fair value has been less than the amortized cost basis, the financial condition and near-term prospects of the security (considering factors such as adverse conditions specific to the security and ratings agency actions), and the intent and ability to retain the investment to allow for an anticipated recovery in fair value. The entire fair value loss on a security that is other-than-temporary impairment is recorded in earnings if we intend to sell the security or if it is more likely than not that we will be required to sell the security before the expected recovery of the loss. However, if the impairment is other-than-temporary, and those two conditions do not exist, the portion of the impairment related to credit losses is recorded in earnings and the impairment related to other factors is recorded in other comprehensive income. Securities classified as trading are accounted for at fair value with unrealized gains and losses included in investment income. Securities that we have the intent and ability to hold to maturity are classified as held-to-maturity and are accounted for at amortized cost unless the security is determined to have an other-than-temporary impairment. In this case it is accounted for in the same manner described above.

We also have other investments, including a receivable for cash collateral posted to derivative counterparties. These investments are accounted for at amortized cost in other investments.

Interest Expense

Interest expense is based upon contractual interest rates adjusted for the amortization of debt issuance costs and premiums and the accretion of discounts. Our interest expense may also be adjusted for net payments/receipts related to interest rate and foreign currency swap agreements and interest rate futures contracts that qualify and are designated as hedges. Interest expense also includes the amortization of deferred gains and losses on closed hedge transactions that qualified as hedges. Amortization of debt issuance costs, premiums, discounts and terminated hedge-basis adjustments are recognized using the effective interest rate method.

Transfer of Financial Assets and Extinguishments of Liabilities

We account for loan sales and debt repurchases in accordance with the applicable accounting guidance. Our securitizations and other asset-backed secured financings are accounted for as on-balance sheet secured borrowings. See “Securitization Accounting” of this Note 2 for further discussion on the criteria assessed to determine whether a transfer of financial assets is a sale or a secured borrowing. If a transfer of loans qualifies as a sale we derecognize the loan and recognize a gain or loss as the difference between the carrying basis of the loan sold and liabilities retained and the compensation received.

We periodically repurchase our outstanding debt in the open market or through public tender offers. We record a gain or loss on the early extinguishment of debt based upon the difference between the carrying cost of the debt and the amount paid to the third party and is net of hedging gains and losses when the debt is in a qualifying hedge relationship.

We recognize the results of a transfer of loans and the extinguishment of debt based upon the settlement date of the transaction.

Securitization Accounting

Our securitizations use a two-step structure with a special purpose entity that legally isolates the transferred assets from us, even in the event of bankruptcy. Transactions receiving sale treatment are also structured to ensure that the holders of the beneficial interests issued are not constrained from pledging or exchanging their interests, and that we do not maintain effective control over the transferred assets. If these criteria are not met, then the transaction is accounted for as an on-balance sheet secured borrowing. In all cases, irrespective of whether they qualify as accounting sales our securitizations are legally structured to be sales of assets that isolate the transferred assets from us. If a securitization qualifies as a sale, we then assess whether we are the primary beneficiary of the securitization trust and are required to consolidate such trust. If we are the primary beneficiary then no gain or loss is recognized. See “Consolidation” of this Note 2 for additional information regarding the accounting rules for consolidation when we are the primary beneficiary of these trusts.

Irrespective of whether a securitization receives sale or on-balance sheet treatment, our continuing involvement with our securitization trusts is generally limited to:

•

Owning the equity certificates of certain trusts.

•

The servicing of the student loan assets within the securitization trusts, on both a pre- and post-default basis.

•

Our acting as administrator for the securitization transactions we sponsored, which includes remarketing certain bonds at future dates.

•

Our responsibilities relative to representation and warranty violations.

•

Temporarily advancing to the trust certain borrower benefits afforded the borrowers of student loans that have been securitized. These advances subsequently are returned to us in the next quarter.

•

Certain back-to-back derivatives entered into by us contemporaneously with the execution of derivatives by certain Private Education Loan securitization trusts.

•

The option held by us to buy certain delinquent loans from certain Private Education Loan securitization trusts.

•

The option to exercise the clean-up call and purchase the student loans from the trust when the asset balance is 10 percent or less of the original loan balance.

•

The option (in certain trusts) to call rate reset notes in instances where the remarketing process has failed.

The investors of the securitization trusts have no recourse to our other assets should there be a failure of the trusts to pay when due. Generally, the only arrangements under which we have to provide financial support to the trusts are representation and warranty violations requiring the buyback of loans.

Under the terms of the transaction documents of certain trusts, we have, from time to time, exercised our options to purchase delinquent loans from Private Education Loan trusts, to purchase the remaining loans from trusts once the loan balance falls below 10 percent of the original amount, or to call rate reset notes. Certain trusts maintain financial arrangements with third parties also typical of securitization transactions, such as derivative contracts (swaps) and bond insurance policies that, in the case of a counterparty failure, could adversely impact the value of any Residual Interest.

We do not record servicing assets or servicing liabilities when our securitization trusts are accounted for as on-balance sheet secured financings. As of December 31, 2013 and 2012, all of our securitization trusts are on-balance sheet, except as discussed in the next sentence, and as a result we do not have servicing assets or liabilities recorded on the consolidated balance sheet related to these securitization trusts. As of December 31, 2013, we have $58 million of servicing assets on our balance sheet related to Residual Interests in FFELP Loan securitization trusts we sold in 2013. See “Note 3 — Student Loans” for further details.

Derivative Accounting

The accounting guidance for our derivative instruments, which includes interest rate swaps, cross-currency interest rate swaps, interest rate futures contracts, interest rate cap contracts and Floor Income Contracts, requires that every derivative instrument, including certain derivative instruments embedded in other contracts, be recorded at fair value on the balance sheet as either an asset or liability. Derivative positions are recorded as net positions by counterparty based on master netting arrangements (see “Note 7 — Derivative Financial Instruments — Risk Management Strategy”) exclusive of accrued interest and cash collateral held or pledged.

Many of our derivatives, mainly interest rate swaps hedging the fair value of fixed-rate assets and liabilities, and cross-currency interest rate swaps, qualify as effective hedges. For these derivatives, the relationship between the hedging instrument and the hedged items (including the hedged risk and method for assessing effectiveness), as well as the risk management objective and strategy for undertaking various hedge transactions at the inception of the hedging relationship, is documented. Each derivative is designated to either a specific (or pool of) asset(s) or liability(ies) on the balance sheet or expected future cash flows, and designated as either a “fair value” or a “cash flow” hedge. Fair value hedges are designed to hedge our exposure to changes in fair value of a fixed rate or foreign denominated asset or liability, while cash flow hedges are designed to hedge our exposure to variability of either a floating rate asset’s or liability’s cash flows or an expected fixed rate debt issuance. For effective fair value hedges, both the derivative and the hedged item (for the risk being hedged) are marked-to-market with any difference reflecting ineffectiveness and recorded immediately in the statement of income. For effective cash flow hedges, the change in the fair value of the derivative is recorded in other comprehensive income, net of tax, and recognized in earnings in the same period as the earnings effects of the hedged item. The ineffective portion of a cash flow hedge is recorded immediately through earnings. The assessment of the hedge’s effectiveness is performed at inception and on an ongoing basis, generally using regression testing. For hedges of a pool of assets or liabilities, tests are performed to demonstrate the similarity of individual instruments of the pool. When it is determined that a derivative is not currently an effective hedge, ineffectiveness is recognized for the full change in value of the derivative with no offsetting mark-to-market of the hedged item for the current period. If it is also determined the hedge will not be effective in the future, we discontinue the hedge accounting prospectively, cease recording changes in the fair value of the hedged item, and begin amortization of any basis adjustments that exist related to the hedged item.

We also have derivatives, primarily Floor Income Contracts and certain basis swaps, that we believe are effective economic hedges but do not qualify for hedge accounting treatment. These derivatives are classified as “trading” and as a result they are marked-to-market through earnings with no consideration for the fair value fluctuation of the economically hedged item.

The “gains (losses) on derivative and hedging activities, net” line item in the consolidated statements of income includes the unrealized changes in the fair value of our derivatives (except effective cash flow hedges which are recorded in other comprehensive income), the unrealized changes in fair value of hedged items in qualifying fair value hedges, as well as the realized changes in fair value related to derivative net settlements and dispositions that do not qualify for hedge accounting. Net settlement income/expense on derivatives that qualify as hedges are included with the income or expense of the hedged item (mainly interest expense).

Servicing Revenue

Servicing revenue includes third-party loan servicing and Guarantor servicing revenue.

We perform loan servicing functions for third-parties in return for a servicing fee. Our compensation is typically based on a per-unit fee arrangement or a percentage of the loans outstanding. We recognize servicing revenues associated with these activities based upon the contractual arrangements as the services are rendered. We recognize late fees on third-party serviced loans as well as on loans in our portfolio according to the contractual provisions of the promissory notes, as well as our expectation of collectability.

We provide a full complement of administrative services to FFELP Guarantors including account maintenance for Guarantor agencies. The fees associated with these services are recognized as the services are performed based on contractually determined rates.

Contingency Revenue

We receive fees for collections of delinquent debt on behalf of clients performed on a contingency basis. Revenue is earned and recognized upon receipt of the delinquent customer funds.

We also receive fees from Guarantor agencies for performing default aversion services on delinquent loans prior to default. The fee is received when the loan is initially placed with us and we are obligated to provide such services for the remaining life of the loan for no additional fee. In the event that the loan defaults, we are obligated to rebate a portion of the fee to the Guarantor agency in proportion to the principal and interest outstanding when the loan defaults. We recognize fees received, net of an estimate of future rebates owed due to subsequent defaults, over the service period which is estimated to be the life of the loan.

Other Income

Our Upromise subsidiary has a number of programs that encourage consumers to save for the cost of college education. We have established a consumer savings network which is designed to promote college savings by consumers who are members of this program who generate rewards when they purchase goods and services from the companies that participate in the program (“Participating Companies”). Participating Companies generally pay Upromise fees based on member purchase volume, either online or in stores depending on the contractual arrangement with the Participating Company. We recognize revenue as marketing and administrative services are rendered based upon contractually determined rates and member purchase volumes.

Goodwill and Acquired Intangible Assets

We account for goodwill and acquired intangible assets in accordance with the applicable accounting guidance. Under this guidance goodwill is not amortized but is tested periodically for impairment. We test goodwill for impairment annually as of October 1 at the reporting unit level, which is the same as or one level below a business segment. Goodwill is also tested at interim periods if an event occurs or circumstances change that would indicate the carrying amount may be impaired.

We assess qualitative factors to determine whether it is “more-likely-than-not” that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The “more-likely-than-not” threshold is defined as having a likelihood of more than 50 percent. If, after assessing relevant qualitative factors, we conclude that it is “more-likely-than-not” that the fair value of a reporting unit as of October 1 is less than its carrying amount, we will complete Step 1 of the goodwill impairment analysis. Step 1 consists of a comparison of the fair value of the reporting unit to the reporting unit’s carrying value, including goodwill. If the carrying value of the reporting unit exceeds the fair value, Step 2 in the goodwill impairment analysis is performed to measure the amount of impairment loss, if any. Step 2 of the goodwill impairment analysis compares the implied fair value of the reporting unit’s goodwill to the carrying value of the reporting unit’s goodwill. The implied fair value of goodwill is determined in a manner consistent with determining goodwill in a business combination. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of the goodwill, an impairment loss is recognized in an amount equal to that excess.

Other acquired intangible assets include but are not limited to tradenames, customer and other relationships, and non-compete agreements. Acquired intangible assets with finite lives are amortized over their estimated useful lives in proportion to their estimated economic benefit. Finite-lived acquired intangible assets are reviewed for impairment using an undiscounted cash flow analysis when an event occurs or circumstances change indicating the carrying amount of a finite-lived asset or asset group may not be recoverable. If the carrying amount of the asset or asset groups exceeds the undiscounted cash flows, the fair value of the asset or asset group is determined using an acceptable valuation technique. An impairment loss would be recognized if the carrying amount of the asset (or asset group) exceeds the fair value of the asset or asset group. The impairment loss recognized would be the difference between the carrying amount and fair value. Indefinite-life acquired intangible assets are not amortized. We test these indefinite life acquired intangible assets for impairment annually as of October 1 or at interim periods if an event occurs or circumstances change that would indicate the carrying value of these assets may be impaired. The annual or interim impairment test of indefinite-lived acquired intangible assets is based primarily on a discounted cash flow analysis.

Restructuring and Other Reorganization Expenses

From time to time we implement plans to restructure our business. In conjunction with these restructuring plans, involuntary benefit arrangements, disposal costs (including contract termination costs and other exit costs), as well as certain other costs that are incremental and incurred as a direct result of our restructuring plans, are classified as restructuring expenses in the accompanying consolidated statements of income.

We sponsor the SLM Corporation Employee Severance Plan (the “Severance Plan”) which provides severance benefits in the event of termination of our full-time employees (with the exception of certain specified levels of management) and part-time employees who work at least 24 hours per week. The Severance Plan establishes specified benefits based on base salary, job level immediately preceding termination and years of service upon termination of employment due to Involuntary Termination or a Job Abolishment, as defined in the Severance Plan. The benefits payable under the Severance Plan relate to past service and they accumulate and vest. Accordingly, we recognize severance costs to be paid pursuant to the Severance Plan when payment of such benefits is probable and reasonably estimable. Such benefits, including severance pay calculated based on the Severance Plan, medical and dental benefits, outplacement services and continuation pay, have been incurred during 2013, 2012 and 2011, as a direct result of our restructuring initiatives. Accordingly, such costs are classified as restructuring expenses in the accompanying consolidated statements of income.

Contract termination costs are expensed at the earlier of (1) the contract termination date or (2) the cease use date under the contract. Other exit costs are expensed as incurred and classified as restructuring expenses if (1) the cost is incremental to and incurred as a direct result of planned restructuring activities and (2) the cost is not associated with or incurred to generate revenues subsequent to our consummation of the related restructuring activities.

Other reorganization expenses include third-party costs and severance incurred in connection with our previously announced plan to separate our existing organization into two distinct publicly-traded entities.

Accounting for Stock-Based Compensation

We recognize stock-based compensation cost in our consolidated statements of income using the fair value based method. Under this method we determine the fair value of the stock-based compensation at the time of the grant and recognize the resulting compensation expense over the vesting period of the stock-based grant.

Income Taxes

We account for income taxes under the asset and liability approach which requires the recognition of deferred tax liabilities and assets for the expected future tax consequences of temporary differences between the carrying amounts and tax basis of our assets and liabilities. To the extent tax laws change, deferred tax assets and liabilities are adjusted in the period that the tax change is enacted.

“Income tax expense/(benefit)” includes (i) deferred tax expense/(benefit), which represents the net change in the deferred tax asset or liability balance during the year plus any change in a valuation allowance, and (ii) current tax expense/(benefit), which represents the amount of tax currently payable to or receivable from a tax authority plus amounts accrued for unrecognized tax benefits. Income tax expense/(benefit) excludes the tax effects related to adjustments recorded in equity.

If we have an uncertain tax position, then that tax position is recognized only if it is more likely than not to be sustained upon examination based on the technical merits of the position. The amount of tax benefit recognized in the financial statements is the largest amount of benefit that is more than fifty percent likely of being sustained upon ultimate settlement of the uncertain tax position. We recognize interest related to unrecognized tax benefits in income tax expense/(benefit), and penalties, if any, in operating expenses.

Earnings (Loss) per Common Share

We compute earnings (loss) per common share (“EPS”) by dividing net income allocated to common shareholders by the weighted average common shares outstanding. Net income allocated to common shareholders represents net income applicable to common shareholders (net income adjusted for preferred stock dividends including dividends declared, accretion of discounts on preferred stock including accelerated accretion when preferred stock is repaid early, and cumulative dividends related to the current dividend period that have not been declared as of period end). Diluted earnings per common share is computed by dividing income allocated to common shareholders by the weighted average common shares outstanding plus amounts representing the dilutive effect of stock options outstanding, restricted stock, restricted stock units, and the outstanding commitment to issue shares under the Employee Stock Purchase Plan. See “Note 10 — Earnings (Loss) per Common Share” for further discussion.

Discontinued Operations

A “Component” of a business comprises operations and cash flows that can be clearly distinguished operationally and for financial reporting purposes from the rest of the Company. When we determine that a Component of our business has been disposed of or has met the criteria to be classified as held-for-sale such Component is presented separately as discontinued operations if the operations of the Component have been or will be eliminated from our ongoing operations and we will have no continuing involvement with the Component after the disposal transaction is complete. If a Component is classified as held-for-sale, then it is carried at the lower of its cost basis or fair value. Included within discontinued operations are the accounting results related to our Campus Solutions and 529 college-savings plan administration business, which have been sold as of December 31, 2013. See “Note 16 — Discontinued Operations” for further discussion.

Statement of Cash Flows

Included in our financial statements is the consolidated statement of cash flows. It is our policy to include all derivative net settlements, irrespective of whether the derivative is a qualifying hedge, in the same section of the statement of cash flows that the derivative is economically hedging.

As discussed in “Restricted Cash and Investments” of this Note 2, our restricted cash balances primarily relate to on-balance sheet securitizations. This balance is primarily the result of timing differences between when principal and interest is collected on the trust assets and when principal and interest is paid on the trust liabilities. As such, changes in this balance are reflected in investing activities.

Reclassifications

Certain reclassifications have been made to the balances as of and for the years ended December 31, 2012 and 2011, to be consistent with classifications adopted for 2013, which had no effect on net income, total assets or total liabilities.

Student Loans

3.	Student Loans

Student loans consist of FFELP and Private Education Loans.

There are three principal categories of FFELP Loans: Stafford, PLUS, and FFELP Consolidation Loans. Generally, Stafford and PLUS Loans have repayment periods of between five and ten years. FFELP Consolidation Loans have repayment periods of twelve to thirty years. FFELP Loans do not require repayment, or have modified repayment plans, while the customer is in-school and during the grace period immediately upon leaving school. The customer may also be granted a deferment or forbearance for a period of time based on need, during which time the customer is not considered to be in repayment. Interest continues to accrue on loans in the in-school, deferment and forbearance period. FFELP Loans obligate the customer to pay interest at a stated fixed rate or a variable rate reset annually (subject to a cap) on July 1 of each year depending on when the loan was originated and the loan type. FFELP Loans disbursed before April 1, 2006 earn interest at the greater of the borrower’s rate or a floating rate based on the SAP formula, with the interest earned on the floating rate that exceeds the interest earned from the customer being paid directly by ED. In low or certain declining interest rate environments when student loans are earning at the fixed borrower rate, and the interest on the funding for the loans is variable and declining, we can earn additional spread income that we refer to as Floor Income. For loans disbursed after April 1, 2006, FFELP Loans effectively only earn at the SAP rate, as the excess interest earned when the borrower rate exceeds the SAP rate (Floor Income) is required to be rebated to ED.

FFELP Loans are insured as to their principal and accrued interest in the event of default subject to a Risk Sharing level based on the date of loan disbursement. These insurance obligations are supported by contractual rights against the United States. For loans disbursed after October 1, 1993 and before July 1, 2006, we receive 98 percent reimbursement on all qualifying default claims. For loans disbursed on or after July 1, 2006, we receive 97 percent reimbursement.

On December 23, 2011, the President signed the Consolidated Appropriations Act of 2012 into law. This law includes changes that permit FFELP lenders or beneficial holders to change the index on which the Special Allowance Payments (“SAP”) are calculated for FFELP Loans first disbursed on or after January 1, 2000. The law allows holders to elect to move the index from the Commercial Paper (“CP”) Rate to the one-month LIBOR rate. We elected to use the one-month LIBOR rate rather than the CP rate commencing on April 1, 2012 in connection with our entire $128 billion of CP indexed loans. This change will help us to better match loan yields with our financing costs. This election did not materially affect our results for 2012.

Our Private Education Loans are made largely to bridge the gap between the cost of higher education and the amount funded through financial aid, federal loans or customers’ resources. Private Education Loans bear the full credit risk of the customer. We manage this additional risk through historical risk-performance underwriting strategies and the addition of qualified cosigners. Private Education Loans generally carry a variable rate indexed to LIBOR or Prime indices. We encourage customers to include a cosigner on the loan, and the majority of loans in our portfolio are cosigned. We also encourage customers to make payments while in school. Similar to FFELP loans, Private Education Loans are generally non-dischargeable in bankruptcy. Most loans have repayment terms of 15 years or more, and for loans made prior to 2009, payments are typically deferred until after graduation; however, since 2009 we began to encourage interest-only or fixed payment options while the customer is enrolled in school and today, the majority of new loans make payments while in school.

The estimated weighted average life of student loans in our portfolio was approximately 7.5 years and 8.0 years at December 31, 2013 and 2012, respectively. The following table reflects the distribution of our student loan portfolio by program.

⁽¹⁾	The FFELP category is primarily Stafford Loans, but also includes federally guaranteed PLUS and HEAL Loans.

As of December 31, 2013 and 2012, 76 percent and 75 percent, respectively, of our student loan portfolio was in repayment.

Loan Sales

In 2013, we sold Residual Interests in FFELP Loan securitization trusts to third parties. We will continue to service the student loans in the trusts under existing agreements. As a result of these transactions, we removed securitization trust assets of $12.5 billion and the related liabilities of $12.1 billion from the balance sheet and recorded a $312 million gain as part of “gains on sales of loans and investments” in 2013.

Certain Collection Tools — Private Education Loans

Forbearance involves granting the customer a temporary cessation of payments (or temporary acceptance of smaller than scheduled payments) for a specified period of time. Using forbearance extends the original term of the loan. Forbearance does not grant any reduction in the total repayment obligation (principal or interest). While in forbearance status, interest continues to accrue and is capitalized to principal when the loan re-enters repayment status. Our forbearance policies include limits on the number of forbearance months granted consecutively and the total number of forbearance months granted over the life of the loan. In some instances, we require good-faith payments before granting forbearance. Exceptions to forbearance policies are permitted when such exceptions are judged to increase the likelihood of collection of the loan. Forbearance as a collection tool is used most effectively when applied based on a customer’s unique situation, including historical information and judgments. We leverage updated customer information and other decision support tools to best determine who will be granted forbearance based on our expectations as to a customer’s ability and willingness to repay their obligation. This strategy is aimed at mitigating the overall risk of the portfolio as well as encouraging cash resolution of delinquent loans.

Forbearance may be granted to customers who are exiting their grace period to provide additional time to obtain employment and income to support their obligations, or to current customers who are faced with a hardship and request forbearance time to provide temporary payment relief. In these circumstances, a customer’s loan is placed into a forbearance status in limited monthly increments and is reflected in the forbearance status at month-end during this time. At the end of the granted forbearance period, the customer will enter repayment status as current and is expected to begin making scheduled monthly payments on a go-forward basis.

Forbearance may also be granted to customers who are delinquent in their payments. In these circumstances, the forbearance cures the delinquency and the customer is returned to a current repayment status. In more limited instances, delinquent customers will also be granted additional forbearance time.

During 2009, we instituted an interest rate reduction program to assist customers in repaying their Private Education Loans through reduced payments, while continuing to reduce their outstanding principal balance. This program is offered in situations where the potential for principal recovery, through a modification of the monthly payment amount, is better than other alternatives currently available. Along with demonstrating the ability and willingness to pay, the customer must make three consecutive monthly payments at the reduced rate to qualify for the program. Once the customer has made the initial three payments, the loan’s status is returned to current and the interest rate is reduced for the successive twelve month period.

Allowance for Loan Losses

4.	Allowance for Loan Losses

Our provisions for loan losses represent the periodic expense of maintaining an allowance sufficient to absorb incurred probable losses, net of expected recoveries, in the held-for-investment loan portfolios. The evaluation of the provisions for loan losses is inherently subjective as it requires material estimates that may be susceptible to significant changes. We believe that the allowance for loan losses is appropriate to cover probable losses incurred in the loan portfolios. We segregate our Private Education Loan portfolio into two classes of loans — traditional and non-traditional. Non-traditional loans are loans to (i) customers attending for-profit schools with an original Fair Isaac and Company (“FICO”) score of less than 670 and (ii) customers attending not-for-profit schools with an original FICO score of less than 640. The FICO score used in determining whether a loan is non-traditional is the greater of the customer or cosigner FICO score at origination. Traditional loans are defined as all other Private Education Loans that are not classified as non-traditional.

Charge-offs are reported net of expected recoveries. For Private Education Loans, the expected recovery amount is transferred to the receivable for partially charged-off loan balance. Charge-offs include charge-offs against the receivable for partially charged-off loans which represents the difference between what was expected to be collected and any shortfalls in what was actually collected in the period. See “Receivable for Partially Charged-Off Private Education Loans” for further discussion.

Key Credit Quality Indicators

FFELP Loans are substantially insured and guaranteed as to their principal and accrued interest in the event of default; therefore, the key credit quality indicator for this portfolio is loan status. The impact of changes in loan status is incorporated quarterly into the allowance for loan losses calculation.

For Private Education Loans, the key credit quality indicators are school type, FICO scores, the existence of a cosigner, the loan status and loan seasoning. The school type/FICO score are assessed at origination and maintained through the traditional/non-traditional loan designation. The other Private Education Loan key quality indicators can change and are incorporated quarterly into the allowance for loan losses calculation. The following table highlights the principal balance (excluding the receivable for partially charged-off loans) of our Private Education Loan portfolio stratified by the key credit quality indicators.

Receivable for Partially Charged-Off Private Education Loans

At the end of each month, for loans that are 212 days past due, we charge off the estimated loss of a defaulted loan balance. Actual recoveries are applied against the remaining loan balance that was not charged off. We refer to this remaining loan balance as the “receivable for partially charged-off loans.” If actual periodic recoveries are less than expected, the difference is immediately charged off through the allowance for loan losses with an offsetting reduction in the receivable for partially charged-off Private Education Loans. If actual periodic recoveries are greater than expected, they will be reflected as a recovery through the allowance for Private Education Loan losses once the cumulative recovery amount exceeds the cumulative amount originally expected to be recovered. Private Education Loans which defaulted between 2008 and 2013 for which we have previously charged off estimated losses have, to varying degrees, not met our post-default recovery expectations to date and may continue not to do so. According to our policy, we have been charging off these periodic shortfalls in expected recoveries against our allowance for Private Education Loan losses and the related receivable for partially charged-off Private Education Loans and we will continue to do so. There was $336 million and $198 million in the allowance for Private Education Loan losses at December 31, 2013 and 2012, respectively, providing for possible additional future charge-offs related to the receivable for partially charged-off Private Education Loans.

The following table summarizes the activity in the receivable for partially charged-off loans.

Represents the current period recovery shortfall – the difference between what was expected to be collected and what was actually collected. These amounts are included in the Private Education Loan total charge-offs as reported in the “Allowance for Loan Losses Metrics” tables.

⁽⁴⁾

The allowance for estimated recovery shortfalls of the receivable for partially charged-off Private Education Loans is a component of the $2.1 billion, $2.2 billion and $2.2 billion overall allowance for Private Education Loan losses as of December 31, 2013, 2012 and 2011, respectively.

Troubled Debt Restructurings (“TDRs”)

We modify the terms of loans for certain customers when we believe such modifications may increase the ability and willingness of a customer to make payments and thus increase the ultimate overall amount collected on a loan. These modifications generally take the form of a forbearance, a temporary interest rate reduction or an extended repayment plan. For customers experiencing financial difficulty, certain Private Education Loans for which we have granted either a forbearance of greater than three months, an interest rate reduction or an extended repayment plan are classified as TDRs. Approximately 45 percent and 43 percent of the loans granted forbearance have qualified as a TDR loan at December 31, 2013, and 2012, respectively. The unpaid principal balance of TDR loans that were in an interest rate reduction plan as of December 31, 2013 and 2012 was $1.5 billion and $1.0 billion, respectively.

At December 31, 2013 and 2012, all of our TDR loans had a related allowance recorded. The following table provides the recorded investment, unpaid principal balance and related allowance for our TDR loans.

5.	Goodwill and Acquired Intangible Assets

Goodwill

All acquisitions must be assigned to a reporting unit or units. A reporting unit is the same as, or one level below, an operating segment. We have four reportable segments: Consumer Lending, Business Services, FFELP Loans and Other. The following table summarizes our goodwill, accumulated impairments and net goodwill for our reporting units and reportable segments.

Goodwill Impairment Testing

We perform our goodwill impairment testing annually in the fourth quarter as of October 1. No goodwill was deemed impaired in 2013. As part of the 2013 annual impairment testing, we retained a third-party appraisal firm to assist in the valuations required to perform Step 1 impairment testing. The income approach was the primary approach used to estimate the fair value of each reporting unit.

The income approach measures the value of each reporting unit’s future economic benefit determined by its discounted cash flows derived from our projections plus an assumed terminal growth rate adjusted for what we believe a market participant would assume in an acquisition. These projections are generally five-year projections that reflect the anticipated cash flow fluctuations of the respective reporting units. If a component of a reporting unit is winding down or is assumed to wind down, the projections extend through the anticipated wind-down period and no residual value is ascribed.

Under our guidance, the third-party appraisal firm developed the discount rate for each reporting unit incorporating such factors as the risk free rate, a market rate of return, a measure of volatility (Beta) and a company-specific and capital markets risk premium, as appropriate, to adjust for volatility and uncertainty in the economy and to capture specific risk related to the respective reporting units. We considered whether an asset sale or an equity sale would be the most likely sale structure for each reporting unit and valued each reporting unit based on the more likely hypothetical scenario.

The discount rates reflect market-based estimates of capital costs and are adjusted for our assessment of a market participant’s view with respect to execution, source concentration and other risks associated with the projected cash flows of individual reporting units. We reviewed and approved the discount rates provided by the third-party appraiser including the factors incorporated to develop the discount rates for each reporting unit.

We and the third-party appraisal firm also considered a market approach for each reporting unit. Market-based multiples for comparable publicly traded companies and similar transactions were evaluated as an indicator of the value of the reporting units to assess the reasonableness of the estimated fair value derived from the income approach.

The following table illustrates the carrying value of equity for each reporting unit with remaining goodwill as of December 31, 2013, and the percentage by which the estimated fair value determined in conjunction with Step 1 impairment testing in the fourth quarter of 2013 exceeds the carrying value of equity.


(Dollars in millions)	Carrying Value of Equity		% of Fair Value in Excess of Carrying Value
FFELP Loans	$	930		202	%
Consumer Lending		4,335		80	%
Servicing		137		966	%
Contingency Services		53		193	%

We acknowledge that continued weakness in the economy coupled with changes in legislation and the regulatory environment could adversely affect the operating results of our reporting units. If the forecasted performance of our reporting units is not achieved, or if our stock price declines resulting in deterioration in our total market capitalization, the fair value of one or more of the reporting units could be significantly reduced, and we may be required to record a charge, which could be material, for an impairment of goodwill.

To assess impairment for the FFELP, Consumer Lending, and Servicing reporting units at October 1, 2012 and 2011, we assessed relevant qualitative factors to determine whether it was “more-likely-than-not” that the fair value of an individual reporting unit was less than its carrying value. These qualitative factors included consideration of the significant amount of excess fair value over the carrying values of these reporting units as of October 1, 2010 when we performed a Step 1 goodwill impairment test and engaged an appraisal firm to estimate the fair values of these reporting units, the current legislative environment, our stock price during 2012 and 2011, market capitalization and EPS results as well as significant reductions in our operating expenses. After assessing these relevant qualitative factors, we determined that it was more-likely-than-not that the fair values of these reporting units exceeded their carrying amounts.

During 2012, we finalized the purchase accounting for a Contingency Services acquisition that resulted in goodwill. We performed Step 1 impairment testing for the Contingency Services reporting unit as of October 1, 2012, resulting in no indicated impairment.

Accumulated impairment and amortization includes impairment amounts only if the acquired intangible asset has been deemed partially impaired. When an acquired intangible asset is considered fully impaired, and no longer in use, the cost basis and any accumulated amortization related to the asset is written off.

⁽²⁾	Intangible assets not subject to amortization include tradenames and trademarks totaling $6 million and $10 million, net of accumulated impairment as of December 31, 2013 and 2012, respectively.

We recorded amortization of acquired intangible assets from continuing operations totaling $13 million, $18 million, and $21 million in 2013, 2012 and 2011, respectively. We will continue to amortize our intangible assets with definite useful lives over their remaining estimated useful lives. We estimate amortization expense associated with these intangible assets will be $9 million, $7 million, $5 million, $2 million and $2 million in 2014, 2015, 2016, 2017 and 2018, respectively.

- Definition

The entire disclosure for the aggregate amount of goodwill and a description of intangible assets, which may include (a) for amortizable intangible assets (also referred to as finite-lived intangible assets), the carrying amount, the amount of any significant residual value, and the weighted-average amortization period, (b) for intangible assets not subject to amortization (also referred to as indefinite-lived intangible assets), the carrying amount, and (c) the amount of research and development assets acquired and written off in the period, including the line item in the income statement in which the amounts written off are aggregated, if not readily apparent from the income statement. Also discloses (a) for amortizable intangibles assets in total and by major class, the gross carrying amount and accumulated amortization, the total amortization expense for the period, and the estimated aggregate amortization expense for each of the five succeeding fiscal years, (b) for intangible assets not subject to amortization the carrying amount in total and by major class, and (c) for goodwill, in total and for each reportable segment, the changes in the carrying amount of goodwill during the period (including the aggregate amount of goodwill acquired, the aggregate amount of impairment losses recognized, and the amount of goodwill included in the gain (loss) on disposal of a reporting unit). If any part of goodwill has not been allocated to a reportable segment, discloses the unallocated amount and the reasons for not allocating. For each impairment loss recognized related to an intangible asset (excluding goodwill), discloses: (a) a description of the impaired intangible asset and the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method for determining fair value, (c) the caption in the income statement or the statement of activities in which the impairment loss is aggregated, and (d) the segment in which the impaired intangible asset is reported. For each goodwill impairment loss recognized, discloses: (a) a description of the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method of determining the fair value of the associated reporting unit, and (c) if a recognized impairment loss is an estimate not finalized and the reasons why the estimate is not final.

Borrowings

6.	Borrowings

Borrowings consist of secured borrowings issued through our securitization program, borrowings through secured facilities, unsecured notes issued by us, term and other deposits at Sallie Mae Bank, and other interest-bearing liabilities related primarily to obligations to return cash collateral held. To match the interest rate and currency characteristics of our borrowings with the interest rate and currency characteristics of our assets, we enter into interest rate and foreign currency swaps with independent parties. Under these agreements, we make periodic payments, generally indexed to the related asset rates or rates which are highly correlated to the asset rates, in exchange for periodic payments which generally match our interest obligations on fixed or variable rate notes (see “Note 7 — Derivative Financial Instruments”). Payments and receipts on our interest rate and currency swaps are not reflected in the following tables.

2013 Sales of FFELP Securitization Trust Residual Interests

On February 13, 2013, we sold the Residual Interest in a FFELP Loan securitization trust to a third party. We will continue to service the student loans in the trust under existing agreements. The sale removed securitization trust assets of $3.82 billion and related liabilities of $3.68 billion from our balance sheet.

On April 11, 2013, we sold the Residual Interest in a FFELP Loan securitization trust to a third party. We will continue to service the student loans in the trust under existing agreements. The sale removed securitization trust assets of $2.03 billion and related liabilities of $1.99 billion from our balance sheet.

On June 13, 2013, we sold the three Residual Interests in FFELP Loan securitization trusts to a third party. We will continue to service the student loans in the trusts under existing agreements. The sale removed securitization trust assets of $6.60 billion and related liabilities of $6.42 billion from our balance sheet.

FFELP Loans — Other Secured Borrowing Facilities

We have various secured borrowing facilities that we use to finance our FFELP loans. Liquidity is available under these secured credit facilities to the extent we have eligible collateral and available capacity. The maximum borrowing capacity under these facilities will vary and is subject to each agreement’s borrowing conditions. These include but are not limited to the facility’s size, current usage and the availability and fair value of qualifying unencumbered FFELP Loan collateral. Our borrowings under these facilities are non-recourse. The maturity dates on these facilities range from June 2014 to January 2016. The interest rate on certain facilities can increase under certain circumstances. The facilities are subject to termination under certain circumstances. As of December 31, 2013 there was approximately $10.0 billion outstanding under these facilities with approximately $10.4 billion of assets securing these facilities. As of December 31, 2013, the maximum unused capacity under these facilities was $10.6 billion. As of December 31, 2013, we had $2.7 billion of unencumbered FFELP Loans.

Private Education Loans — Other Secured Borrowing Facilities

We have a facility that was used to fund the call and redemption of our SLM 2009-D Private Education Loan Trust ABS, which occurred on August 15, 2013. The maturity date of the new facility is August 15, 2015. Our borrowings under this facility are non-recourse. The interest rate can increase under certain circumstances. The facility is subject to termination under certain circumstances. As of December 31, 2013, there was $843 million outstanding under the facility. The book basis of the assets securing the facility as of December 31, 2013 was $1.6 billion. Additional borrowings are not available under this facility.

Other Funding Sources

Deposits

Sallie Mae Bank raises deposits through intermediaries in the brokered Certificate of Deposit (“CD”) market and through direct retail deposit channels. As of December 31, 2013, bank deposits totaled $9.2 billion of which $4.5 billion were brokered term deposits, $4.4 billion were retail and other deposits and $299 million were deposits from affiliates that eliminate in our consolidated balance sheet. Cash and liquid investments totaled $2.2 billion as of December 31, 2013.

In addition to its deposit base, Sallie Mae Bank has borrowing capacity with the Federal Reserve Bank (“FRB”) through a collateralized lending facility. FRB is not obligated to lend; however, in general we can borrow as long as Sallie Mae Bank is generally in sound financial condition. Borrowing capacity is limited by the availability of acceptable collateral. As of December 31, 2013, borrowing capacity was approximately $900 million and there were no outstanding borrowings.

Senior Unsecured Debt

We issued $3.75 billion, $2.7 billion and $2.0 billion of unsecured debt in 2013, 2012 and 2011, respectively.

Debt Repurchases

Risk Management Strategy

We maintain an overall interest rate risk management strategy that incorporates the use of derivative instruments to minimize the economic effect of interest rate changes. Our goal is to manage interest rate sensitivity by modifying the repricing frequency and underlying index characteristics of certain balance sheet assets and liabilities so the net interest margin is not, on a material basis, adversely affected by movements in interest rates. We do not use derivative instruments to hedge credit risk associated with debt we issued. As a result of interest rate fluctuations, hedged assets and liabilities will appreciate or depreciate in market value. Income or loss on the derivative instruments that are linked to the hedged assets and liabilities will generally offset the effect of this unrealized appreciation or depreciation for the period the item is being hedged. We view this strategy as a prudent management of interest rate sensitivity. In addition, we utilize derivative contracts to minimize the economic impact of changes in foreign currency exchange rates on certain debt obligations that are denominated in foreign currencies. As foreign currency exchange rates fluctuate, these liabilities will appreciate and depreciate in value. These fluctuations, to the extent the hedge relationship is effective, are offset by changes in the value of the cross-currency interest rate swaps executed to hedge these instruments. Management believes certain derivative transactions entered into as hedges, primarily Floor Income Contracts and basis swaps, are economically effective; however, those transactions generally do not qualify for hedge accounting under GAAP (as discussed below) and thus may adversely impact earnings.

Although we use derivatives to offset (or minimize) the risk of interest rate and foreign currency changes, the use of derivatives does expose us to both market and credit risk. Market risk is the chance of financial loss resulting from changes in interest rates, foreign exchange rates and market liquidity. Credit risk is the risk that a counterparty will not perform its obligations under a contract and it is limited to the loss of the fair value gain in a derivative that the counterparty owes us. When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, have no credit risk exposure to the counterparty; however, the counterparty has exposure to us. We minimize the credit risk in derivative instruments by entering into transactions with highly rated counterparties that are reviewed regularly by our Credit Department. We also maintain a policy of requiring that all derivative contracts be governed by an International Swaps and Derivative Association Master Agreement. Depending on the nature of the derivative transaction, bilateral collateral arrangements generally are required as well. When we have more than one outstanding derivative transaction with the counterparty, and there exists legally enforceable netting provisions with the counterparty (i.e., a legal right to offset receivable and payable derivative contracts), the “net” mark-to-market exposure, less collateral the counterparty has posted to us, represents exposure with the counterparty. When there is a net negative exposure, we consider our exposure to the counterparty to be zero. At December 31, 2013 and 2012, we had a net positive exposure (derivative gain positions to us less collateral which has been posted by counterparties to us) related to SLM Corporation and Sallie Mae Bank derivatives of $83 million and $79 million, respectively.

Our on-balance sheet securitization trusts have $10.7 billion of Euro and British Pound Sterling denominated bonds outstanding as of December 31, 2013. To convert these non-U.S. dollar denominated bonds into U.S dollar liabilities, the trusts have entered into foreign-currency swaps with highly–rated counterparties. In addition, the trusts have entered into $12.8 billion of interest rates swaps which are primarily used to convert Prime received on securitized student loans to LIBOR paid on the bonds. At December 31, 2013, the net positive exposure on swaps in securitization trusts is $968 million.

Our securitization trusts had total net exposure of $772 million related to financial institutions located in France; of this amount, $577 million carries a guaranty from the French government. The total exposure relates to $5.1 billion notional amount of cross-currency interest rate swaps held in our securitization trusts, of which $3.4 billion notional amount carries a guaranty from the French government. Counterparties to the cross currency interest rate swaps are required to post collateral when their credit rating is withdrawn or downgraded below a certain level. As of December 31, 2013, no collateral was required to be posted and we are not holding any collateral related to these contracts. Adjustments are made to our derivative valuations for counterparty credit risk. The adjustments made at December 31, 2013 related to derivatives with French financial institutions (including those that carry a guaranty from the French government) decreased the derivative asset value by $63 million. Credit risks for all derivative counterparties are assessed internally on a continual basis.

Accounting for Derivative Instruments

Derivative instruments that are used as part of our interest rate and foreign currency risk management strategy include interest rate swaps, basis swaps, cross-currency interest rate swaps, and interest rate floor contracts with indices that relate to the pricing of specific balance sheet assets and liabilities. The accounting for derivative instruments requires that every derivative instrument, including certain derivative instruments embedded in other contracts, be recorded on the balance sheet as either an asset or liability measured at its fair value. As more fully described below, if certain criteria are met, derivative instruments are classified and accounted for by us as either fair value or cash flow hedges. If these criteria are not met, the derivative financial instruments are accounted for as trading.

Fair Value Hedges

Fair value hedges are generally used by us to hedge the exposure to changes in fair value of a recognized fixed rate asset or liability. We enter into interest rate swaps to economically convert fixed rate assets into variable rate assets and fixed rate debt into variable rate debt. We also enter into cross-currency interest rate swaps to economically convert foreign currency denominated fixed and floating debt to U.S. dollar denominated variable debt. For fair value hedges, we generally consider all components of the derivative’s gain and/or loss when assessing hedge effectiveness and generally hedge changes in fair values due to interest rates or interest rates and foreign currency exchange rates or the total change in fair values.

Cash Flow Hedges

We use cash flow hedges to hedge the exposure to variability in cash flows for a forecasted debt issuance and for exposure to variability in cash flows of floating rate debt. This strategy is used primarily to minimize the exposure to volatility from future changes in interest rates. Gains and losses on the effective portion of a qualifying hedge are recorded in accumulated other comprehensive income and ineffectiveness is recorded immediately to earnings. In the case of a forecasted debt issuance, gains and losses are reclassified to earnings over the period which the stated hedged transaction affects earnings. If we determine it is not probable that the anticipated transaction will occur, gains and losses are reclassified immediately to earnings. In assessing hedge effectiveness, generally all components of each derivative’s gains or losses are included in the assessment. We generally hedge exposure to changes in cash flows due to changes in interest rates or total changes in cash flow.

Trading Activities

When derivative instruments do not qualify as hedges, they are accounted for as trading instruments where all changes in fair value are recorded through earnings. We sell interest rate floors (Floor Income Contracts) to hedge the embedded Floor Income options in student loan assets. The Floor Income Contracts are written options which have a more stringent hedge effectiveness hurdle to meet. Specifically, our Floor Income Contracts do not qualify for hedge accounting treatment because the pay down 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. Additionally, the term, the interest rate index and the interest rate index reset frequency of the Floor Income Contracts are different from that of the student loans. Therefore, Floor Income Contracts do not qualify for hedge accounting treatment, and are recorded as trading instruments. Regardless of the accounting treatment, we consider these contracts to be economic hedges for risk management purposes. We use this strategy to minimize our exposure to changes in interest rates.

We use basis swaps to minimize earnings variability caused by having different reset characteristics on our interest-earning assets and interest-bearing liabilities. These swaps possess a term of up to 13 years and are primarily indexed to LIBOR or Prime rates. The specific terms and notional amounts of the swaps are determined based on a review of our asset/liability structure, our assessment of future interest rate relationships, and on other factors such as short-term strategic initiatives. Hedge accounting requires that when using basis swaps, 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; however, they generally do not meet this effectiveness criterion because the index of the swap does not exactly match the index of the hedged assets. Additionally, some of our FFELP Loans can earn at either a variable or a fixed interest rate depending on market interest rates and, therefore, swaps economically hedging these FFELP Loans do not meet the criteria for hedge accounting treatment. As a result, these swaps are recorded at fair value with changes in fair value reflected currently in the statement of income.

⁽¹⁾

Fair values reported are exclusive of collateral held and pledged and accrued interest. Assets and liabilities are presented without consideration of master netting agreements. Derivatives are carried on the balance sheet based on net position by counterparty under master netting agreements, and classified in other assets or other liabilities depending on whether in a net positive or negative position.

⁽²⁾	“Other” includes embedded derivatives bifurcated from securitization debt as well as derivatives related to our Total Return Swap Facility and back-to-back private credit floors.

⁽³⁾	The following table reconciles gross positions with the impact of master netting agreements to the balance sheet classification:


	Other Assets						Other Liabilities

Net position	$	937		$	818		$	(794	)	$	(982	)

The above fair values include adjustments for counterparty credit risk for both when we are exposed to the counterparty, net of collateral postings, and when the counterparty is exposed to us, net of collateral postings. The net adjustments decreased the overall net asset positions at December 31, 2013 and 2012 by $91 million and $111 million, respectively. In addition, the above fair values reflect adjustments for illiquid derivatives as indicated by a wide bid/ask spread in the interest rate indices to which the derivatives are indexed. These adjustments decreased the overall net asset positions at December 31, 2013 and 2012 by $84 million and $107 million, respectively.

⁽¹⁾	At December 31, 2013 and 2012, $0 million and $9 million, respectively, were held in restricted cash accounts.

⁽²⁾	The trusts do not have the ability to sell or re-pledge securities they hold as collateral.

Our corporate derivatives contain credit contingent features. At our current unsecured credit rating, we have fully collateralized our corporate derivative liability position (including accrued interest and net of premiums receivable) of $762 million with our counterparties. Further downgrades would not result in any additional collateral requirements, except to increase the frequency of collateral calls. Two counterparties have the right to terminate the contracts with further downgrades. We currently have a liability position with these derivative counterparties (including accrued interest and net of premiums receivable) of $148 million and have posted $148 million of collateral to these counterparties. If the credit contingent feature was triggered for these two counterparties and the counterparties exercised their right to terminate, we would not be required to deliver additional assets to settle the contracts. Trust related derivatives do not contain credit contingent features related to our or the trusts’ credit ratings.

- Definition

The entire disclosure for derivative instruments and hedging activities including, but not limited to, risk management strategies, non-hedging derivative instruments, assets, liabilities, revenue and expenses, and methodologies and assumptions used in determining the amounts.

The “Derivatives at fair value” line in the above table represents the fair value of our derivatives in a gain position by counterparty, exclusive of accrued interest and collateral. At December 31, 2013 and 2012, these balances included $1.6 billion and $2.4 billion, respectively, of cross-currency interest rate swaps and interest rate swaps designated as fair value hedges that were offset by an increase in interest-bearing liabilities related to the hedged debt. As of December 31, 2013 and 2012, the cumulative mark-to-market adjustment to the hedged debt was $(2.1) billion and $(2.8) billion, respectively.

Equity [Abstract]

Stockholders' Equity

9.	Stockholders’ Equity

Preferred Stock

At December 31, 2013, we had outstanding 3.3 million shares of 6.97 percent Cumulative Redeemable Preferred Stock, Series A (the “Series A Preferred Stock”) and 4.0 million shares of Floating-Rate Non-Cumulative Preferred Stock, Series B (the “Series B Preferred Stock”). Neither series has a maturity date but can be redeemed at our option. Redemption would include any accrued and unpaid dividends up to the redemption date. The shares have no preemptive or conversion rights and are not convertible into or exchangeable for any of our other securities or property. Dividends on both series are not mandatory and are paid quarterly, when, as, and if declared by the Board of Directors. Holders of Series A Preferred Stock are entitled to receive cumulative, quarterly cash dividends at the annual rate of $3.485 per share. Holders of Series B Preferred Stock are entitled to receive quarterly dividends based on 3-month LIBOR plus 170 basis points per annum in arrears. Upon liquidation or dissolution of the Company, holders of the Series A and Series B Preferred Stock are entitled to receive $50 and $100 per share, respectively, plus an amount equal to accrued and unpaid dividends for the then current quarterly dividend period, if any, pro rata, and before any distribution of assets are made to holders of our common stock.

Common Stock

Our shareholders have authorized the issuance of 1.125 billion shares of common stock (par value of $.20). At December 31, 2013, 429 million shares were issued and outstanding and 31 million shares were unissued but encumbered for outstanding stock options, restricted stock units and dividend equivalent units for employee compensation and remaining authority for stock-based compensation plans. The stock-based compensation plans are described in “Note 11 — Stock-Based Compensation Plans and Arrangements.”

In March 2011, we retired 70 million shares of common stock held in treasury. This retirement decreased the balance in treasury stock by $1.9 billion, with corresponding decreases of $14 million in common stock and $1.9 billion in additional paid-in capital. There was no impact to total equity from this transaction.

Dividend and Share Repurchase Program

In 2013, we increased the quarterly dividend on our common stock to $.15 per share, up from $.125 per share in the prior year. In 2013, we authorized the repurchase of up to $800 million of outstanding common stock in open market transactions and we repurchased 27 million shares for an aggregate purchase price of $600 million. In 2012, we authorized the repurchase of up to $900 million of outstanding common stock in open market transactions and we repurchased 58 million shares for an aggregate purchase price of $900 million. In 2011, we authorized the repurchase of up to $300 million of outstanding common stock in open market transactions and we repurchased 19 million shares for an aggregate purchase price of $300 million.

The following table summarizes our common share repurchases and issuances.

Stock-Based Compensation Plans and Arrangements

11.

Stock-Based Compensation Plans and Arrangements

As of December 31, 2013, we have one active stock-based compensation plan that provides for grants of equity awards to our employees and non-employee directors. We also maintain the ESPP. Shares issued under these stock-based compensation plans may be either shares reacquired by us or shares that are authorized but unissued.

Our SLM Corporation 2012 Omnibus Incentive Plan was approved by shareholders on May 24, 2012. At December 31, 2013, 20 million shares were authorized to be issued from this plan.

An amendment to our ESPP was approved by our shareholders on May 24, 2012 that authorized the issuance of 6 million shares under the plan and kept the terms of the plan substantially the same.

The total stock-based compensation cost recognized in the consolidated statements of income for 2013, 2012 and 2011 was $47 million, $47 million and $56 million, respectively. As of December 31, 2013, there was $19 million of total unrecognized compensation expense related to unvested stock awards net of estimated forfeitures, which is expected to be recognized over a weighted average period of 1.8 years. We amortize compensation expense on a straight-line basis over the related vesting periods of each tranche of each award.

Stock Options

Stock options granted prior to 2012 expire 10 years after the grant date, and those granted since 2012 expire in 5 years. The exercise price must be equal to or greater than the market price of our common stock on the grant date. We have granted time-vested, price-vested and performance-vested options to our employees and non-employee directors. Time-vested options granted to management and non-management employees generally vest over three years. Price-vested options granted to management employees vest upon our common stock reaching a targeted closing price for a set number of days. Performance-vested options granted to management employees vest one-third per year for three years based on corporate earnings-related performance targets. Options granted to non-employee directors vest upon the director’s election to the Board.

The fair values of the options granted in the years ended December 31, 2013, 2012 and 2011 were estimated as of the grant date using a Black-Scholes option pricing model with the following weighted average assumptions:


	Years Ended December 31,
	2013			2012			2011
Risk-free interest rate		.65	%		.60	%		1.57	%
Expected volatility		31	%		44	%		54	%
Expected dividend rate		3.35	%		3.13	%		2.58	%
Expected life of the option		2.8 years			2.8 years			4.1 years
Weighted average fair value of options granted	$	3.11		$	4.12		$	5.18

The expected life of the options is based on observed historical exercise patterns. Groups of employees (and non-employee directors) that have received similar option grant terms are considered separately for valuation purposes. The expected volatility is based on implied volatility from publicly-traded options on our stock at the grant date and historical volatility of our stock consistent with the expected life of the option. The risk-free interest rate is based on the U.S. Treasury spot rate at the grant date consistent with the expected life of the option. The dividend yield is based on the projected annual dividend payment per share based on the dividend amount at the grant date, divided by the stock price at the grant date.

The following table summarizes stock option activity in 2013.


(Dollars in millions, except per share data)	Number of Options			Weighted Average Exercise Price per Share		Weighted Average Remaining Contractual Term		Aggregate Intrinsic Value⁽¹⁾
Outstanding at December 31, 2012		25,992,747		$	19.84
Granted		3,980,008			17.92
Exercised⁽²⁾⁽³⁾		(7,614,500	)		12.81
Canceled		(2,085,495	)		34.94

Outstanding at December 31, 2013⁽⁴⁾⁽⁵⁾		20,272,760		$	20.55		4.1 yrs	$	198

Exercisable at December 31, 2013		14,426,174		$	21.84		4.1 yrs	$	145

⁽¹⁾

The aggregate intrinsic value represents the total intrinsic value (the aggregate difference between our closing stock price on December 31, 2013 and the exercise price of in-the-money options) that would have been received by the option holders if all in-the-money options had been exercised on December 31, 2013.

⁽²⁾

The total intrinsic value of options exercised was $73 million, $27 million and $14 million for 2013, 2012 and 2011, respectively.

⁽³⁾

No cash was received from option exercises in 2013. The actual tax benefit realized for the tax deductions from option exercises totaled $28 million for 2013.

⁽⁴⁾

As of December 31, 2013, there was $4 million of unrecognized compensation cost related to stock options net of estimated forfeitures, which is expected to be recognized over a weighted average period of 1.5 years.

⁽⁵⁾

For net-settled options, gross number is reflected.

Restricted Stock

Restricted stock awards generally vest over three years and in some cases based on corporate earnings-related performance targets. Outstanding restricted stock is entitled to dividend equivalent units that vest subject to the same vesting requirements or lapse of transfer restrictions, as applicable, as the underlying restricted stock award. The fair value of restricted stock awards is based on our stock price at the grant date.

The following table summarizes restricted stock activity in 2013.


	Number of Shares			Weighted Average Grant Date Fair Value
Non-vested at December 31, 2012		187,792		$	11.55
Granted		51,073			17.91
Vested⁽¹⁾		(193,370	)		12.47
Canceled		(6,140	)		17.91

Non-vested at December 31, 2013⁽²⁾		39,355		$	14.29

⁽¹⁾

The total fair value of shares that vested during 2013, 2012 and 2011 was $2 million, $4 million and $6 million, respectively.

⁽²⁾

As of December 31, 2013, there was $.01 million of unrecognized compensation cost related to restricted stock net of estimated forfeitures, which is expected to be recognized over a weighted average period of .1 years.

Restricted Stock Units and Performance Stock Units

Restricted stock units (“RSUs”) and performance stock units (“PSUs”) are equity awards granted to employees that entitle the holder to shares of our common stock when the award vests. RSUs may be time-vested over three years or vested at grant but subject to transfer restrictions, while PSUs vest based on corporate earnings-related performance targets over a three-year period. Outstanding RSUs and PSUs are entitled to dividend equivalent units that vest subject to the same vesting requirements or lapse of transfer restrictions, as applicable, as the underlying award. The fair value of RSUs and PSUs is based on our stock price at the grant date.

The following table summarizes RSU and PSU activity in 2013.


	Number of RSUs/ PSUs			Weighted Average Grant Date Fair Value
Outstanding at December 31, 2012		4,473,464		$	15.49
Granted		2,457,570			17.98
Vested and converted to common stock⁽¹⁾		(1,730,669	)		15.32
Canceled		(73,478	)		16.52

Outstanding at December 31, 2013⁽²⁾		5,126,887		$	16.72

⁽¹⁾

The total fair value of RSUs/PSUs that vested and converted to common stock during 2013, 2012 and 2011 was $27 million, $13 million and $.4 million, respectively.

⁽²⁾

As of December 31, 2013, there was $15 million of unrecognized compensation cost related to RSUs/PSUs net of estimated forfeitures, which is expected to be recognized over a weighted average period of 1.8 years.

Employee Stock Purchase Plan

Under the ESPP, employees can purchase shares of our common stock at the end of a 12-month offering period at a price equal to the share price at the beginning of the 12-month period, less 15 percent, up to a maximum purchase price of $7,500 plus accrued interest. The purchase price for each offering is determined at the beginning of the offering period.

The fair values of the stock purchase rights of the ESPP offerings were calculated using a Black-Scholes option pricing model with the following weighted average assumptions.


	Years Ended December 31,
	2013			2012			2011
Risk-free interest rate		.15	%		.13	%		.27	%
Expected volatility		29	%		29	%		42	%
Expected dividend rate		3.51	%		3.27	%		1.87	%
Expected life of the option		1 year			1 year			1 year
Weighted average fair value of stock purchase rights	$	2.95		$	3.01		$	3.63

The expected volatility is based on implied volatility from publicly-traded options on our stock at the grant date and historical volatility of our stock consistent with the expected life. The risk-free interest rate is based on the U.S. Treasury spot rate at the grant date consistent with the expected life. The dividend yield is based on the projected annual dividend payment per share based on the current dividend amount at the grant date divided by the stock price at the grant date.

The fair values were amortized to compensation cost on a straight-line basis over a one-year vesting period. As of December 31, 2013, there was $.1 million of unrecognized compensation cost related to the ESPP net of estimated forfeitures, which is expected to be recognized in January 2014.

During 2013, 2012 and 2011, plan participants purchased 218,389 shares, 192,755 shares and 278,266 shares, respectively, of our common stock.

Fair Value Disclosures [Abstract]

Fair Value Measurements

12.

Fair Value Measurements

We use estimates of fair value in applying various accounting standards for our financial statements.

We categorize our fair value estimates based on a hierarchical framework associated with three levels of price transparency utilized in measuring financial instruments at fair value. For additional information regarding our policies for determining fair value and the hierarchical framework, see “Note 2 — Significant Accounting Policies — Fair Value Measurement.”

During 2013, there were no significant transfers of financial instruments between levels.

Student Loans

Our FFELP Loans and Private Education Loans are accounted for at cost or at the lower of cost or market if the loan is held-for-sale. FFELP Loans classified as held-for-sale are those which we have the ability and intent to sell under various ED loan purchase programs. In these instances, the FFELP Loans are valued using the committed sales price under the programs. For all other FFELP Loans and Private Education Loans, fair values were determined by modeling loan cash flows using stated terms of the assets and internally-developed assumptions to determine aggregate portfolio yield, net present value and average life.

FFELP Loans

The significant assumptions used to determine fair value of our FFELP loans are prepayment speeds, default rates, cost of funds, capital levels, and expected Repayment Borrower Benefits to be earned. In addition, the Floor Income component of our FFELP Loan portfolio is valued with option models using both observable market inputs and internally developed inputs. A number of significant inputs into the models are internally derived and not observable to market participants. While the resulting fair value can be validated against market transactions where we are a participant, these markets are not considered active. As such, these are level 3 valuations.

Private Education Loans

The significant assumptions used to determine fair value of our Private Education Loans are prepayment speeds, default rates, recovery rates, cost of funds and capital levels. A number of significant inputs into the models are internally derived and not observable to market participants nor can the resulting fair values be validated against market transactions. As such, these are level 3 valuations.

Cash and Investments (Including “Restricted Cash and Investments”)

Cash and cash equivalents are carried at cost. Carrying value approximates fair value. Investments classified as trading or available-for-sale are carried at fair value in the financial statements. Investments in mortgage-backed securities are valued using observable market prices. These securities are primarily collateralized by real estate properties in Utah and are guaranteed by either a government sponsored enterprise or the U.S. government. Other investments (primarily municipal bonds) for which observable prices from active markets are not available were valued through standard bond pricing models using observable market yield curves adjusted for credit and liquidity spreads. These valuations are immaterial to the overall investment portfolio. The fair value of investments in commercial paper, asset-backed commercial paper, or demand deposits that have a remaining term of less than 90 days when purchased are estimated to equal their cost and, when needed, adjustments for liquidity and credit spreads are made depending on market conditions and counterparty credit risks. No additional adjustments were deemed necessary. These are level 2 valuations.

Borrowings

Borrowings are accounted for at cost in the financial statements except when denominated in a foreign currency or when designated as the hedged item in a fair value hedge relationship. When the hedged risk is the benchmark interest rate and not full fair value, the cost basis is adjusted for changes in value due to benchmark interest rates only. Foreign currency-denominated borrowings are re-measured at current spot rates in the financial statements. The full fair value of all borrowings is disclosed. Fair value was determined through standard bond pricing models and option models (when applicable) using the stated terms of the borrowings, observable yield curves, foreign currency exchange rates, volatilities from active markets or from quotes from broker-dealers. Fair value adjustments for unsecured corporate debt are made based on indicative quotes from observable trades and spreads on credit default swaps specific to the Company. Fair value adjustments for secured borrowings are based on indicative quotes from broker-dealers. These adjustments for both secured and unsecured borrowings are material to the overall valuation of these items and, currently, are based on inputs from inactive markets. As such, these are level 3 valuations.

Derivative Financial Instruments

All derivatives are accounted for at fair value in the financial statements. The fair value of a majority of derivative financial instruments was determined by standard derivative pricing and option models using the stated terms of the contracts and observable market inputs. In some cases, we utilized internally developed inputs that are not observable in the market, and as such, classified these instruments as level 3 fair values. Complex structured derivatives or derivatives that trade in less liquid markets require significant estimates and judgment in determining fair value that cannot be corroborated with market transactions. It is our policy to compare our derivative fair values to those received by our counterparties in order to validate the model’s outputs. Any significant differences are identified and resolved appropriately.

When determining the fair value of derivatives, we take into account counterparty credit risk for positions where there is exposure to the counterparty on a net basis by assessing exposure net of collateral held. The net exposures for each counterparty are adjusted based on market information available for the specific counterparty, including spreads from credit default swaps. When the counterparty has exposure to us under derivatives with us, we fully collateralize the exposure, minimizing the adjustment necessary to the derivative valuations for our credit risk. While trusts that contain derivatives are not required to post collateral, when the counterparty is exposed to the trust the credit quality and securitized nature of the trusts minimizes any adjustments for the counterparty’s exposure to the trusts. The net credit risk adjustment (adjustments for our exposure to counterparties net of adjustments for the counterparties’ exposure to us) decreased the valuations by $91 million at December 31, 2013.

Inputs specific to each class of derivatives disclosed in the table below are as follows:

•

Interest rate swaps — Derivatives are valued using standard derivative cash flow models. Derivatives that swap fixed interest payments for LIBOR interest payments (or vice versa) and derivatives swapping quarterly reset LIBOR for daily reset LIBOR or one-month LIBOR were valued using the LIBOR swap yield curve which is an observable input from an active market. These derivatives are level 2 fair value estimates in the hierarchy. Other derivatives swapping LIBOR interest payments for another variable interest payment (primarily T-Bill or Prime) or swapping interest payments based on the Consumer Price Index for LIBOR interest payments are valued using the LIBOR swap yield curve and observable market spreads for the specified index. The markets for these swaps are generally illiquid as indicated by a wide bid/ask spread. The adjustment made for liquidity decreased the valuations by $84 million at December 31, 2013. These derivatives are level 3 fair value estimates.

•

Cross-currency interest rate swaps — Derivatives are valued using standard derivative cash flow models. Derivatives hedging foreign-denominated bonds are valued using the LIBOR swap yield curve (for both USD and the foreign-denominated currency), cross-currency basis spreads, and forward foreign currency exchange rates. The derivatives are primarily British Pound Sterling and Euro denominated. These inputs are observable inputs from active markets. Therefore, the resulting valuation is a level 2 fair value estimate. Amortizing notional derivatives (derivatives whose notional amounts change based on changes in the balance of, or pool of, assets or debt) hedging trust debt use internally derived assumptions for the trust assets’ prepayment speeds and default rates to model the notional amortization. Management makes assumptions concerning the extension features of derivatives hedging rate-reset notes denominated in a foreign currency. These inputs are not market observable; therefore, these derivatives are level 3 fair value estimates.

•

Floor Income Contracts — Derivatives are valued using an option pricing model. Inputs to the model include the LIBOR swap yield curve and LIBOR interest rate volatilities. The inputs are observable inputs in active markets and these derivatives are level 2 fair value estimates.

The carrying value of borrowings designated as the hedged item in a fair value hedge is adjusted for changes in fair value due to benchmark interest rates and foreign-currency exchange rates. These valuations are determined through standard bond pricing models and option models (when applicable) using the stated terms of the borrowings, and observable yield curves, foreign currency exchange rates, and volatilities.

The following table summarizes the valuation of our financial instruments that are marked-to-market on a recurring basis.

The significant inputs that are unobservable or from inactive markets related to our level 3 derivatives detailed in the table above would be expected to have the following impacts to the valuations:

•

Consumer Price Index/LIBOR basis swaps — These swaps do not actively trade in the markets as indicated by a wide bid/ask spread. A wider bid/ask spread will result in a decrease in the overall valuation.

•

Prime/LIBOR basis swaps — These swaps do not actively trade in the markets as indicated by a wide bid/ask spread. A wider bid/ask spread will result in a decrease in the overall valuation. In addition, the unobservable inputs include Constant Prepayment Rates of the underlying securitization trust the swap references. A decrease in this input will result in a longer weighted average life of the swap which will increase the value for swaps in a gain position and decrease the value for swaps in a loss position, everything else equal. The opposite is true for an increase in the input.

•

Cross-currency interest rate swaps — The unobservable inputs used in these valuations are Constant Prepayment Rates of the underlying securitization trust the swap references. A decrease in this input will result in a longer weighted average life of the swap. All else equal in a typical currency market, this will result in a decrease to the valuation due to the delay in the cash flows of the currency exchanges as well as diminished liquidity in the forward exchange markets as you increase the term. The opposite is true for an increase in the input.

Commitments, Contingencies and Guarantees

At the time of this filing, Sallie Mae Bank remains subject to a cease and desist order originally issued in August 2008 by the FDIC and the UDFI. In July 2013, the FDIC notified us that it plans to replace the existing cease and desist order on Sallie Mae Bank with a new formal enforcement action against Sallie Mae Bank that would more specifically address certain cited violations of Section 5 of the Federal Trade Commission Act (the “FTC Act”), including practices relating to payment allocation practices and the disclosures and assessments of certain late fees, as well as alleged violations under the Servicemembers Civil Relief Act (the “SCRA”). In November 2013, the FDIC notified us that the new formal enforcement action would be against Sallie Mae Bank and an additional enforcement action would be against Sallie Mae, Inc. (“SMI”), in its capacity as a servicer of education loans for other financial institutions, and would include civil money penalties and restitution. Sallie Mae Bank has been notified by the UDFI that it does not intend to join the FDIC in issuing any new enforcement action. With respect to alleged civil violations of the SCRA, Sallie Mae Bank and SMI are also separately negotiating a comprehensive settlement, remediation and restitution plan with the Department of Justice (the “DOJ”), in its capacity as the agency having primary authority for enforcement of such matters. As of December 31, 2013, we reserved $70 million for estimated amounts and costs that are probable of being incurred for expected compliance remediation efforts with respect to the FDIC and DOJ matters described above.

We have made and continue to make changes to Sallie Mae Bank’s oversight of significant activities performed outside Sallie Mae Bank by affiliates and to our business practices in order to comply with all applicable laws and regulations and the terms of any cease and desist orders, including in connection with our pursuit of a strategic plan to separate our existing organization into two publicly-traded companies. We are cooperating fully with the FDIC, DOJ and Consumer Financial Protection Bureau (the “CFPB”) in response to their investigations and requests for information and are in active discussions with each with respect to any potential actions to be taken against us. We could be required to, or otherwise determine to, make further changes to the business practices and products of Sallie Mae Bank and our other affiliates to respond to regulatory concerns.

Contingencies

In the ordinary course of business, we and our subsidiaries are defendants in or parties to pending and threatened legal actions and proceedings including actions brought on behalf of various classes of claimants. These actions and proceedings may be based on alleged violations of consumer protection, securities, employment and other laws. In certain of these actions and proceedings, claims for substantial monetary damage are asserted against us and our subsidiaries.

In the ordinary course of business, we and our subsidiaries are subject to regulatory examinations, information gathering requests, inquiries and investigations. In connection with formal and informal inquiries in these cases, we and our subsidiaries receive numerous requests, subpoenas and orders for documents, testimony and information in connection with various aspects of our regulated activities.

In view of the inherent difficulty of predicting the outcome of such litigation and regulatory matters, we cannot predict what the eventual outcome of the pending matters will be, what the timing or the ultimate resolution of these matters will be, or what the eventual loss, fines or penalties related to each pending matter may be.

We are required to establish reserves for litigation and regulatory matters where those matters present loss contingencies that are both probable and estimable. When loss contingencies are not both probable and estimable, we do not establish reserves.

Based on current knowledge, reserves have been established for certain litigation or regulatory matters where the loss is both probable and estimable. Based on current knowledge, management does not believe that loss contingencies, if any, arising from pending investigations, litigation or regulatory matters will have a material adverse effect on our consolidated financial position, liquidity, results of operations or cash flows.

Effective tax rate		37.1	%		34.6	%		35.3	%

The effective tax rates for discontinued operations for the years ended December 31, 2013, 2012 and 2011 are 16.2 percent, 40.7 percent, and 37.7 percent, respectively. The effective tax rate varies from the statutory U.S. federal rate of 35 percent primarily due to the release of valuation allowances against capital loss carryforwards for 2013, and due to the impact of state taxes, net of federal benefit, for 2013, 2012 and 2011.

Included in other deferred tax assets is a valuation allowance of $19 million and $29 million as of December 31, 2013 and 2012, respectively, against a portion of our federal, state and international deferred tax assets. The valuation allowance is primarily attributable to deferred tax assets for federal and state capital loss carryovers and state and international net operating loss carryovers that management believes it is more likely than not will expire prior to being realized. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income of the appropriate character (i.e. capital or ordinary) during the period in which the temporary differences become deductible. Management considers, among other things, the economic slowdown, the scheduled reversals of deferred tax liabilities, and the history of positive taxable income available for net operating loss carrybacks in evaluating the realizability of the deferred tax assets.

As of December 31, 2013, we have apportioned state net operating loss carryforwards of $438 million which begin to expire in 2024 and international net operating loss carryforwards of $.3 million which begin to expire in 2032.

As of December 31, 2013, the gross unrecognized tax benefits are $56.0 million. Included in the $56.0 million are $28.1 million of unrecognized tax benefits that, if recognized, would favorably impact the effective tax rate.

The Company or one of its subsidiaries files income tax returns at the U.S. federal level, in most U.S. states, and various foreign jurisdictions. U.S. federal income tax returns filed for years 2010 and prior have either been audited or surveyed and are now resolved. Various combinations of subsidiaries, tax years, and jurisdictions remain open for review, subject to statute of limitations periods (typically 3 to 4 prior years). We do not expect the resolution of open audits to have a material impact on our unrecognized tax benefits.

Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

We monitor and assess our ongoing operations and results by three primary operating segments — the Consumer Lending operating segment, the Business Services operating segment and the FFELP Loans operating segment. These three operating segments meet the quantitative thresholds for reportable segments. Accordingly, the results of operations of our Consumer Lending, Business Services and FFELP Loans segments are presented separately. We have smaller operating segments that consist of business operations that have either been discontinued or are winding down. These operating segments do not meet the quantitative thresholds to be considered reportable segments. As a result, the results of operations for these operating segments (Purchased Paper business and mortgage and other loan business) are combined with gains/losses from the repurchase of debt, the financial results of our corporate liquidity portfolio and all overhead within the Other reportable segment. The management reporting process measures the performance of our operating segments based on our management structure, as well as the methodology we used to evaluate performance and allocate resources. Management, including our chief operating decision makers, evaluates the performance of our operating segments based on their profitability. As discussed further below, we measure the profitability of our operating segments based on “Core Earnings.” Accordingly, information regarding our reportable segments is provided based on a “Core Earnings” basis.

Consumer Lending Segment

In this segment, we originate, acquire, finance and service Private Education Loans. The Private Education Loans we make are primarily to bridge the gap between the cost of higher education and the amount funded through financial aid, federal loans or customers’ resources. We continue to offer loan products to parents and graduate students where we believe we are competitive with similar federal education loan products. In this segment, we earn net interest income on our Private Education Loan portfolio (after provision for loan losses). Operating expenses for this segment include costs incurred to acquire and to service our loans. With the elimination of FFELP in July 2010, these FFELP-related revenue sources will continue to decline.

Managed growth of our Private Education Loan portfolio is central not only to our strategy for growing the Consumer Lending segment but also for the future of Sallie Mae Bank. In 2013, we originated $3.8 billion of Private Education Loans, an increase of 14 percent and 39 percent from the years ended December 31, 2012 and 2011, respectively. As of December 31, 2013, 2012 and 2011, we had $37.5 billion, $36.9 billion, and $36.3 billion of Private Education Loans outstanding, respectively.

Private Education Loans bear the full credit risk of the customer and cosigner. We manage this risk by underwriting and pricing based upon customized credit scoring criteria and the addition of qualified cosigners. For the year ended December 31, 2013, our annual charge-off rate for Private Education Loans (as a percentage of loans in repayment) was 2.8 percent, as compared with 3.4 percent for the prior year.

Since the beginning of 2006, virtually all of our Private Education Loans have been originated and funded by Sallie Mae Bank. At December 31, 2013, Sallie Mae Bank had total assets of $10.7 billion, including $6.7 billion in Private Education Loans and $1.4 billion of FFELP Loans. As of the same date, Sallie Mae Bank had total deposits of $9.2 billion. Sallie Mae Bank currently relies on both retail and brokered deposits to fund its assets and periodically sells originated Private Education Loans to affiliates for inclusion in securitization trusts or collection.

We face competition for Private Education Loans from a group of the nation’s larger banks and local credit unions.

The following table includes asset information for our Consumer Lending segment.

Business Services Segment

We are currently the largest holder, servicer and collector of loans made under the previously existing FFELP, and the majority of our income has been derived, directly or indirectly, from our portfolio of FFELP Loans and servicing we have provided for FFELP Loans. In 2010, Congress passed legislation ending the origination of education loans under FFELP. The terms and conditions of existing FFELP Loans were not affected by this legislation. Our FFELP Loan portfolio will amortize over approximately 20 years. The fee income we have earned from providing servicing and contingent collections services on such loans will similarly decline over time. We also provide servicing, loan default aversion and defaulted loans collection services on behalf of Guarantors of FFELP Loans and other institutions, including the ED. With the elimination of FFELP in July 2010, these FFELP-related revenue sources will continue to decline.

•

Servicing revenues from the FFELP Loans we own and manage represent intercompany charges to the FFELP Loans segment at rates paid to us by the trusts which own the loans. These fees are legally the first payment priority of the trusts and exceed the actual cost of servicing the loans. Intercompany loan servicing revenues declined to $530 million in 2013 from $670 million in 2012. Intercompany loan servicing revenues will decline as the FFELP portfolio amortizes. Prepayments of FFELP Loans could further accelerate the rate of decline.

•

In 2013, we earned account maintenance fees on FFELP Loans serviced for Guarantors of $38 million, down from $44 million in 2012. These fees will continue to decline as the portfolio amortizes. Prepayments of FFELP Loans could further accelerate the rate of decline.

•

We provide default aversion, post default collections and claims processing to 15 of the 30 Guarantor agencies that serve as an intermediary between the U.S. federal government and FFELP lenders and are responsible for paying the claims made on defaulted loans. In 2013, collection revenue from Guarantor clients totaled $303 million, compared to $264 million the prior year. As FFELP Loans are no longer originated, these revenues will generally decline over time unless we acquire additional work for Guarantor clients. The rate at which these revenues will decrease will also be affected by the Bipartisan Budget Act (the “Budget Act”) enacted on December 26, 2013 and effective on July 1, 2014, which reduces the amount to be paid to Guarantor agencies for defaulted FFELP Loans that are rehabilitated under Section 428F of the Higher Education Act (the “HEA”). The precise effect of the Budget Act will depend on the decisions of our Guarantor agency clients about their continued participation in FFELP default collections, as well as by how the fee reduction is implemented by ED. We earned approximately $283 million in fee income from these activities in 2013.

In 2013, FFELP-related revenues accounted for 77 percent of total Business Services segment revenues, as compared with 82 percent and 82 percent, respectively, for the previous two years. Total Business Services segment revenues were $1.16 billion for the year ended December 31, 2013, down from $1.20 billion for the prior year.

ED Collection and Servicing Contracts

Since 1997, we have provided collection services on defaulted student loans to ED. The current contract runs through April 21, 2015. There are 21 other collection providers, of which we compete with 16 providers for account allocation based on quarterly performance metrics. The remaining five providers are small businesses that are ensured a particular allocation of business. As a consistent top performer, our share of allocated accounts has ranged from six percent to eight percent for this contract period. Currently, we are participating in ED’s procurement process for a new debt collection contract and expect them to announce the recipients by April 30, 2014.

Since the second quarter of 2009, we have been one of four large servicers awarded a servicing contract by ED to service Direct Student Loan Program (“DSLP”) federal loans owned by ED. We serviced approximately 5.7 million accounts under this DSLP servicing contract as of December 31, 2013. The DSLP servicing contract spans five years with one five-year renewal at the option of ED. In November 2013, ED gave notice to Sallie Mae of its intent to exercise its five-year renewal option to extend the DSLP servicing contract. As such, we will continue to compete for DSLP servicing volume from ED with the three other large servicing companies that also have similar contracts. New account allocations for the upcoming contract year are awarded annually based on each company’s performance on five different metrics over the most recently ended contract year: defaulted borrower count, defaulted borrower dollar amount, a survey of borrowers, a survey of schools and a survey of ED personnel. Pursuant to the contract terms related to annual volume allocation of new loans, the maximum any servicer could be awarded is 40 percent of net new borrowers in that contract year. Our share of new loans serviced for ED under the contract increased to 18 percent in 2013 from 15 percent in the prior contract year as a result of our relative standing, as compared to other servicing companies, on the ED Scorecard. We earned $109 million of revenue under the contract for the year ended December 31, 2013.

Other

Upromise generates transaction fees through our Upromise consumer savings network. Since inception through December 31, 2013, members have earned approximately $800 million in rewards by purchasing products at hundreds of online retailers, booking travel, purchasing a home, dining out, buying gas and groceries, using the Upromise World MasterCard, or completing other qualified transactions. We earn a fee for the marketing and administrative services we provide to companies that participate in the Upromise savings network. We also compete with other loyalty shopping services and companies.

Previously, we provided program management services for 529 college-savings plans through our 529 college-savings plan administration business and our Campus Solutions business provided processing capabilities to educational institutions designed to help campus business offices increase their services to students and families. However, in the second quarter of 2013, we sold our Campus Solutions business and recorded an after-tax gain of $38 million. Additionally, in the fourth quarter of 2013, we sold our 529 college-savings plan administration business and recorded an after-tax gain of $65 million. The results of both of these businesses are reported in discontinued operations for all periods presented.

At December 31, 2013 and 2012, the Business Services segment had total assets of $892 million and $867 million, respectively.

FFELP Loans Segment

Our FFELP Loans segment consists of our FFELP Loan portfolio (approximately $104.6 billion as of December 31, 2013) and the underlying debt and capital funding the loans. We are currently the largest holder of FFELP Loans. FFELP Loans are insured or guaranteed by state or not-for-profit agencies and are also protected by contractual rights to recovery from the United States pursuant to guaranty agreements among ED and these agencies. These guarantees generally cover at least 97 percent of a FFELP Loan’s principal and accrued interest for loans disbursed. In the case of death, disability or bankruptcy of the borrower, these guarantees cover 100 percent of the loan’s principal and accrued interest.

As a result of the long-term funding used in the FFELP Loan portfolio and the insurance and guarantees provided on these loans, the net interest margin recorded in the FFELP Loans segment is relatively stable and the capital we choose to retain with respect to the segment is modest.

In 2013, we sold Residual Interests in FFELP Loan securitization trusts to third parties. We continue to service the student loans in the trusts under existing agreements. As a result of the sale of the Residual Interests in FFELP securitizations, we removed securitization trust assets of $12.5 billion and the related liabilities of $12.1 billion from our balance sheet and recorded a $312 million gain as part of “gains on sales of loans and investments” for the year ended December 31, 2013.

Our FFELP Loan portfolio will amortize over approximately 20 years. Our goal is to maximize the cash flow generated by the portfolio. We will seek to acquire other third-party FFELP Loan portfolios to add net interest income and servicing revenue.

HEA continues to regulate every aspect of the FFELP, including ongoing communications with borrowers and default aversion requirements. Failure to service a FFELP Loan properly could jeopardize the insurance and guarantees and federal support on these loans. The insurance and guarantees on our existing loans were not affected by the July 2010 termination of the FFELP program.

Other Segment

The Other segment consists primarily of the financial results related to activities of our holding company, including the repurchase of debt, the corporate liquidity portfolio and all overhead. We also include results from certain, smaller wind-down and discontinued operations within this segment. Overhead expenses include costs related to executive management, the Board of Directors, accounting, finance, legal, human resources, stock-based compensation expense and certain information technology costs related to infrastructure and operations.

At December 31, 2013 and 2012, the Other segment had total assets of $3.0 billion and $1.8 billion, respectively.

Measure of Profitability

The tables below include the condensed operating results for each of our reportable segments. Management, including the chief operating decision makers, evaluates the Company on certain performance measures that we refer to as “Core Earnings” performance measures for each operating segment. We use “Core Earnings” to manage each business segment because “Core Earnings” reflect adjustments to GAAP financial results for two items, discussed below, that create significant volatility mostly due to timing factors generally beyond the control of management. Accordingly, we believe that “Core Earnings” provide management with a useful basis from which to better evaluate results from ongoing operations against the business plan or against results from prior periods. Consequently, we disclose this information as we believe it provides investors with additional information regarding the operational and performance indicators that are most closely assessed by management. The two items adjusted for in our “Core Earnings” presentations are (1) our use of derivative instruments to hedge our economic risks that do not qualify for hedge accounting treatment or do qualify for hedge accounting treatment but result in ineffectiveness and (2) the accounting for goodwill and acquired intangible assets. The tables presented below reflect “Core Earnings” operating measures reviewed and utilized by management to manage the business. Reconciliation of the “Core Earnings” segment totals to our consolidated operating results in accordance with GAAP is also included in the tables below.

Our “Core Earnings” performance measures are not defined terms within GAAP and may not be comparable to similarly titled measures reported by other companies. Unlike financial accounting, there is no comprehensive, authoritative guidance for management reporting. The management reporting process measures the performance of the operating segments based on the management structure of the Company and is not necessarily comparable with similar information for any other financial institution. Our operating segments are defined by the products and services they offer or the types of customers they serve, and they reflect the manner in which financial information is currently evaluated by management. Intersegment revenues and expenses are netted within the appropriate financial statement line items consistent with the income statement presentation provided to management. Changes in management structure or allocation methodologies and procedures may result in changes in reported segment financial information.

Summary of “Core Earnings” Adjustments to GAAP

The two adjustments required to reconcile from our “Core Earnings” results to our GAAP results of operations relate to differing treatments for: (1) our use of derivative instruments to hedge our economic risks that do not qualify for hedge accounting treatment or do qualify for hedge accounting treatment but result in ineffectiveness and (2) the accounting for goodwill and acquired intangible assets. The following table reflects aggregate adjustments associated with these areas.

“Core Earnings” adjustments to GAAP:
Net impact of derivative accounting⁽¹⁾	$	243		$	(194	)	$	(540	)

Total “Core Earnings” adjustments to GAAP	$	128		$	(123	)	$	(344	)


⁽¹⁾ Derivative accounting: “Core Earnings” exclude periodic unrealized gains and losses that are caused by the mark-to-market valuations on derivatives that do not qualify for hedge accounting treatment under GAAP as well as the periodic unrealized gains and losses that are a result of ineffectiveness recognized related to effective hedges under GAAP. These unrealized gains and losses occur in our Consumer Lending, FFELP Loans and Other business segments. Under GAAP, for our derivatives that are held to maturity, the cumulative net unrealized gain or loss over the life of the contract will equal $0 except for Floor Income Contracts where the cumulative unrealized gain will equal the amount for which we sold the contract. In our “Core Earnings” presentation, we recognize the economic effect of these hedges, which generally results in any net settlement cash paid or received being recognized ratably as an interest expense or revenue over the hedged item’s life.
⁽²⁾ Goodwill and acquired intangible assets: Our “Core Earnings” exclude goodwill and intangible asset impairment and amortization of acquired intangible assets.
⁽³⁾ Net Tax Effect: Such tax effect is based upon our “Core Earnings” effective tax rate for the year.

Discontinued Operations And Disposal Groups [Abstract]

Discontinued Operations

Discontinued Operations

In 2013, we sold our Campus Solutions business and our 529 college-savings plan administration business and recorded an after-tax gain of $38 million and $65 million, respectively. These businesses comprise operations and cash flows that can be clearly distinguished operationally and for financial reporting purposes from the rest of the Company and we will have no continuing involvement.

Risks And Uncertainties [Abstract]

Concentrations of Risk

17.

Concentrations of Risk

Our business is primarily focused in providing and/or servicing to help students and their families save, plan and pay for college. We primarily originate, service and/or collect loans made to students and their families to finance the cost of their education. We provide funding, delivery and servicing support for education loans in the United States, through our Private Education Loan programs and as a servicer and collector of loans for ED. In addition we are the largest holder, servicer and collector of loans under the discontinued FFELP. Because of this concentration in one industry, we are exposed to credit, legislative, operational, regulatory, and liquidity risks associated with the student loan industry.

Concentration Risk in the Revenues Associated with Private Education Loans

We compete in the private credit lending business with banks and other consumer lending institutions, some with strong consumer brand name recognition and greater financial resources. We compete based on our products, origination capability and customer service. To the extent our competitors compete aggressively or more effectively, we could lose market share to them or subject our existing loans to refinancing risk. Our product offerings may not prove to be profitable and may result in higher than expected losses.

We are a leading provider of saving- and paying-for-college products and programs. This concentration gives us a competitive advantage in the marketplace. This concentration also creates risks in our business, particularly in light of our concentrations as a Private Education Loan lender and as a servicer for the FFELP and DSLP. If population demographics result in a decrease in college-age individuals, if demand for higher education decreases, if the cost of attendance of higher education decreases, if public resistance to higher education costs increases, or if the demand for higher education loans decreases, our consumer lending business could be negatively affected. In addition, the federal government, through the DSLP, poses significant competition to our private credit loan products. If loan limits under the DSLP increase, DSLP loans could be more widely available to students and their families and DSLP loans could increase, resulting in further decreases in the size of the Private Education Loan market and demand for our Private Education Loan products.

Concentration Risk in the Revenues Associated with FFELP Loans

On July 1, 2010, the HCERA legislation eliminated FFELP Loan originations, a major source of our net income. All federal loans to students are now made through the DSLP. The terms and conditions of existing FFELP Loans were not affected by this legislation. Despite the end of FFELP, Congress, ED and the Administration still exercise significant authority over the servicing and administration of existing FFELP Loans. Because of the ongoing uncertainty around efforts to reduce the federal budget deficit, the timing, method and manner of implementation of various education lending initiatives has become less predictable.

The net interest margin we earn on our FFELP Loan portfolio, which totaled $1.5 billion in 2013, will decline over time as the portfolio amortizes.

We also earn maintenance fees for the life of the loan for servicing the Guarantor’s portfolio of loans. The portfolio that generates the maintenance fee is now in runoff, and the maintenance fees we earn will decline ratably with the portfolio. We earned maintenance fees of $38 million in 2013.

Our student loan contingent collection business is also affected by HCERA. We currently have 15 Guarantors as clients. We earn revenue from Guarantors for collecting defaulted loans as well as for managing their portfolios of defaulted loans. In 2013, collection revenue from Guarantor clients totaled $303 million. We anticipate that revenue from Guarantors will begin to steadily decline as the portfolio of defaulted loans we manage is resolved and amortizes.

Concentration Risk in the Servicing of Direct Loans

The DSLP is serviced by four private sector institutions, including Sallie Mae. Defaulted Direct Loans are collected by 22 private sector companies, including Sallie Mae. Because of the concentration of our business in servicing and collecting on Direct Loans, we are exposed to risks associated with ED reducing the amount of new loan servicing and collections allocated to us or the termination of our servicing or collection contracts.

•

Our acting as administrator for the securitization transactions we sponsored, which includes remarketing certain bonds at future dates.

•

Our responsibilities relative to representation and warranty violations.

•

Temporarily advancing to the trust certain borrower benefits afforded the borrowers of student loans that have been securitized. These advances subsequently are returned to us in the next quarter.

•

Certain back-to-back derivatives entered into by us contemporaneously with the execution of derivatives by certain Private Education Loan securitization trusts.

•

The option held by us to buy certain delinquent loans from certain Private Education Loan securitization trusts.

•

The option to exercise the clean-up call and purchase the student loans from the trust when the asset balance is 10 percent or less of the original loan balance.

•

The option (in certain trusts) to call rate reset notes in instances where the remarketing process has failed.

Discontinued Operations

Discontinued Operations

A “Component” of a business comprises operations and cash flows that can be clearly distinguished operationally and for financial reporting purposes from the rest of the Company. When we determine that a Component of our business has been disposed of or has met the criteria to be classified as held-for-sale such Component is presented separately as discontinued operations if the operations of the Component have been or will be eliminated from our ongoing operations and we will have no continuing involvement with the Component after the disposal transaction is complete. If a Component is classified as held-for-sale, then it is carried at the lower of its cost basis or fair value. Included within discontinued operations are the accounting results related to our Campus Solutions and 529 college savings plan administration business, which have been sold as of December 31, 2013. See “Note 16 — Discontinued Operations” for further discussion.

Derivative accounting: “Core Earnings” exclude periodic unrealized gains and losses that are caused by the mark-to-market valuations on derivatives that do not qualify for hedge accounting treatment under GAAP as well as the periodic unrealized gains and losses that are a result of ineffectiveness recognized related to effective hedges under GAAP. These unrealized gains and losses occur in our Consumer Lending, FFELP Loans and Other business segments. Under GAAP, for our derivatives that are held to maturity, the cumulative net unrealized gain or loss over the life of the contract will equal $0 except for Floor Income Contracts where the cumulative unrealized gain will equal the amount for which we sold the contract. In our “Core Earnings” presentation, we recognize the economic effect of these hedges, which generally results in any net settlement cash paid or received being recognized ratably as an interest expense or revenue over the hedged item’s life.

⁽²⁾	Goodwill and acquired intangible assets: Our “Core Earnings” exclude goodwill and intangible asset impairment and amortization of acquired intangible assets.

⁽³⁾	Net Tax Effect: Such tax effect is based upon our “Core Earnings” effective tax rate for the year.
