Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2021

The financial reporting and accounting policies of SLM Corporation 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. Actual results could differ from those estimates. Key accounting policies that include significant judgments and estimates include the valuation of allowance for credit losses.

Consolidation

The consolidated financial statements include the accounts of SLM Corporation and its majority-owned and controlled subsidiaries after eliminating the effects of intercompany accounts and transactions.

We consolidate any variable interest entity (“VIE”) where we have determined we are the primary beneficiary. The primary beneficiary is the entity which has both: (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance; and (ii) the obligation to absorb losses or receive benefits of the entity that could potentially be significant to the VIE.

Cash and Cash Equivalents

Cash and Cash Equivalents Cash and cash equivalents include cash held in the Federal Reserve Bank of San Francisco (the “FRB”) and commercial bank accounts, and other short-term liquid instruments with original maturities of three months or less. Fees associated with investing cash and cash equivalents are amortized into interest income using the effective interest rate method.

Trading and Available-for-Sale Investments

Trading Investments

We periodically sell Private Education Loans through securitization transactions where we are required to retain a five percent vertical risk retention interest (i.e., five percent of each class issued in the securitizations). We classified those vertical risk retention interests related to the transactions as available-for-sale investments, except for the interest in the residual classes, which we classified as trading investments recorded at fair value with changes recorded through earnings.

Available-for-Sale Investments

Investments consisted of mortgage-backed securities, Utah Housing Corporation bonds, and U.S. government-sponsored enterprises and Treasury securities. We record our investment purchases and sales on a trade date basis. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts, which are amortized using the effective interest rate method.

Our investments are classified as available-for-sale and reported at fair value. Unrealized gains or losses on available-for-sale investments are recorded in equity and reported as a component of other comprehensive income (loss), net of applicable income taxes.

We assess unrealized losses on available-for-sale debt securities that we have the ability and intent to hold for a period of time sufficient to recover the amortized cost of the security, for the purpose of determining credit impairment. If any credit impairment exists, an allowance for losses is established for the amount of the unrealized loss that is determined to be credit-related.

Other Investments

Other InvestmentsWe hold investments in non-marketable securities and account for these investments at cost, less impairment, plus or minus observable price changes of identical or similar securities of the same issuer.

Loans Held for Investment

Loans, consisting of Private Education Loans, FFELP Loans, and our suite of credit cards (“Credit Cards”) 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 discussed under “Loan Interest Income.” Loans which are held for investment are reported net of an allowance for credit losses.

Loans Held for Sale

Any loans we have not classified as held for investment are classified as held-for-sale and are 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. When a decision has been made to sell loans not previously classified as held for sale, such loans are transferred into the held-for-sale classification and carried at the lower of amortized cost basis (which excludes any allowance for credit losses) or fair value. At the time of the transfer to the held-for-sale classification, any amount by which the amortized cost basis exceeds fair value is accounted for as a valuation allowance. In addition, once a loan is classified as held-for-sale, we reverse any allowance for loan loss applicable to these loans.

As market conditions permit, we may sell or securitize loans as a source of financing for other loans. Due to varying 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 education loans are initially categorized as held for investment. It is only when we have selected the loans to sell or securitize and the transaction qualifies as a sale that 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 or sale, then the fair value of the loans is higher than their respective cost basis and no valuation allowance is recorded.

Restricted Cash

Restricted CashRestricted 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.

Allowance For Credit Losses

Allowance for Credit Losses

Adoption of CECL

On January 1, 2020, we adopted the Financial Accounting Standards Board’s (“FASB’s”) Accounting Standard Update (“ASU”) No. 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“CECL”). Under this guidance, for all loans carried at amortized cost, upon loan origination we are required to measure our allowance for credit losses based on our estimate of all current expected credit losses over the remaining contractual term of the assets. Updates to that estimate each period are recorded through provision expense. The estimate of loan losses must be based on historical experience, current conditions, and reasonable and supportable forecasts. The ASU does not mandate the use of any specific method for estimating credit loss, permitting companies to use judgment in selecting the approach that is most appropriate in their circumstances.

Adoption of the standard had a material impact on how we record and report our financial condition and results of operations, and on regulatory capital. The following table illustrates the impact of the cumulative effect adjustment made upon adoption of CECL on January 1, 2020:


	January 1, 2020
(Dollars in thousands)	As reported under CECL		Pre-CECL Adoption		Impact of CECL Adoption
Assets:
Allowance for credit losses:
Private Education Loans	$	1,435,130	$	374,300	$	1,060,830
FFELP Loans	4,485		1,633		2,852
Personal Loans	145,060		65,877		79,183
Credit Cards	290		102		188
Total	$	1,584,965	$	441,912	$	1,143,053

Deferred tax asset	$	415,540	$	109,369	$	306,171

Liabilities:
Allowance for credit losses:
Off-balance sheet exposures	$	118,239	$	2,481	$	115,758

Equity:
Retained Earnings	$	897,873	$	1,850,512	$	(952,639)

This transition adjustment shown above is inclusive of qualitative adjustments incorporated into our CECL allowance as necessary, to address any limitations in the models used.

Under regulations issued by the FDIC and other federal banking agencies, banking organizations that adopt CECL during the 2020 calendar year, including the Bank, may elect to delay for two years, and then phase in over the following three years, the effects on regulatory capital of CECL relative to the incurred loss methodology. The Bank has elected to use this option. Therefore, the regulatory capital impact of the Bank’s transition adjustments recorded on January 1, 2020 from the adoption of CECL, and 25 percent of the ongoing impact of CECL on the Bank’s allowance for credit losses, retained earnings, and average total consolidated assets, each as reported for regulatory capital purposes (collectively, the “adjusted transition amounts”), were deferred for the two-year period ending January 1, 2022. From January 1, 2022 to January 1, 2025, the adjusted transition amounts will be phased in for regulatory capital purposes at a rate of 25 percent per year, with the phased-in amounts included in regulatory capital at the beginning of each year. For additional information, see Note 18, “Regulatory Capital.”

Allowance for Credit Losses - 2021 and 2020

We maintain an allowance for credit losses for the lifetime expected credit losses on loans in our portfolios, as well as for future loan commitments, at the reporting date.

In determining the lifetime expected credit losses on our Private Education Loan portfolio loan segments, we use a discounted cash flow model. This method requires us to project future principal and interest cash flows on our loans in those portfolios.

To estimate the future expected cash flows, we use a vintage-based model that considers life of loan loss expectations, prepayments (both voluntary and involuntary), defaults, recoveries, and any other adjustments deemed necessary, to determine the adequacy of the allowance at each balance sheet date. These cash flows are discounted at the loan’s effective interest rate to calculate the present value of those cash flows. Management adjusts the effective interest rate used to discount expected cash flows to incorporate expected prepayments. The difference between the present value of those cash flows and the amortized cost basis of the underlying loans is the allowance for credit losses. Entities that measure credit losses based on the present value of expected future cash flows are permitted to report the entire change in present value as credit loss expense, but may alternatively report the change in present value due to the passage of time as interest income. We have elected to report the entire change in present value as credit loss expense.

In determining the loss rates used for the vintage-based approach, we start with our historical loss rates, stratify the loans within each vintage, and then adjust the loss rates based upon economic factors forecasted over a reasonable and supportable forecast period. The reasonable and supportable forecast period is meant to represent the period in which we

believe we can estimate the impact of forecasted economic factors in our expected losses. At the end of the reasonable and supportable forecast period, we immediately revert our forecast of expected losses to our historical averages. We use a two-year reasonable and supportable forecast period, although this period is subject to change as our view evolves on our ability to reasonably forecast economic conditions to estimate future losses.

In estimating our current expected credit losses, we use a combination of expected economic scenarios coupled with our historical experience to derive a base case adjusted for any qualitative factors (as described below). We also develop an adverse and favorable economic scenario. At each reporting date, we determine the appropriate weighting of these alternate scenarios based upon the current economic conditions and our view of the risks of alternate outcomes. This weighting of expectations is used in calculating our current expected credit losses recorded each period.

In estimating recoveries, we use both estimates of what we would receive from the sale of defaulted loans as well as historical borrower payment behavior to estimate the timing and amount of future recoveries on charged-off loans.

We use historical experience and economic forecasts to estimate future prepayment speeds. As with our loss forecasts, at the end of the two-year reasonable and supportable forecast for prepayments, we immediately revert to our historical long-term prepayment rates.

In addition to the above modeling approach, we also take certain other qualitative factors into consideration when calculating the allowance for credit losses. These qualitative factors include, but are not limited to, changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not already included in the analysis, and the effect of other external factors such as legal and regulatory requirements on the level of estimated current expected credit losses.

The evaluation of the allowance for credit losses is inherently subjective, as it requires material estimates that may be susceptible to significant changes. If actual future performance in delinquency, charge-offs, and recoveries is significantly different than estimated, or management assumptions or practices were to change, this could materially affect the estimate of the allowance for credit losses, the timing of when losses are recognized, and the related provision for credit losses on our consolidated statements of income.

When calculating our allowance for credit losses and liability for unfunded commitments, we incorporate several inputs that are subject to change period to period. These include, but are not limited to, CECL model inputs and any overlays deemed necessary by management. The most impactful CECL model inputs include:

•Economic forecasts;

•Weighting of economic forecasts;

•Prepayment speeds; and

•Recovery rates.

Management overlays can encompass a broad array of factors not captured by model inputs, including but not limited to, changes in servicing policies, collection administrative practices, state law changes that could impact servicing and collection practices, and observed differences between forecasted and actual results.

Allowance for Private Education Loan Losses

Allowance for Private Education Loan Losses - 2021 and 2020

In addition to the key assumptions/estimates described above, some estimates are unique to our Private Education Loan portfolio. Estimates are made on our Private Education Loans regarding when each borrower will separate from school. The cash flow timing of when a borrower will begin making full principal and interest payments is dependent upon when the student either graduates or leaves school. These dates can change based upon many factors. We receive information regarding projected graduation dates from a third-party clearinghouse. The separation from school date is updated quarterly based on updated information received from the clearinghouse.

Additionally, when we have a contractual obligation to fund a loan or a portion of a loan at a later date, we make an estimate regarding the percentage of this obligation that will be funded. This estimate is based on historical experience. For unfunded commitments, we recognize the related life of loan allowance as a liability. Once the loan is funded, that liability transfers to the allowance for Private Education Loan losses.

Key Credit Quality Indicators - Private Education Loans - 2021 and 2020

We determine the collectability of our Private Education Loan portfolio by evaluating certain risk characteristics. We consider credit score at original approval and periodically refreshed/updated credit scores through the loan’s term, existence of a cosigner, loan status, and loan seasoning as the key credit quality indicators because they have the most significant effect on the determination of the adequacy of our allowance for credit losses. Credit scores are an indicator of the creditworthiness of borrowers and the higher the credit scores the more likely it is the borrowers will be able to make all of their contractual payments. Loan status affects the credit risk because a past due loan is more likely to result in a credit loss than a current loan. Additionally, loans in the 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 as well. We monitor and update these credit quality indicators in the analysis of the adequacy of our allowance for credit losses on a quarterly basis.

We collect on defaulted loans through a mix of in-house collectors, third-party collectors, and sales to third-parties. For December 31, 2021 and 2020, we used both an estimate of recovery rates from in-house collections as well as expectations of future sales of defaulted loans to estimate the timing and amount of future recoveries on charged-off loans.

Private Education Loans generally do not require borrowers to begin principal and interest repayment until at least six months after the borrowers have graduated or otherwise separated from school. Consequently, the loss estimates for these loans are generally low while the borrower is in school and then increase upon the end of the grace period after separation from school. At both December 31, 2021 and 2020, 24 percent of the principal balance of the Private Education Loan portfolio was related to borrowers who were then in an in-school (fully deferred), grace, or other deferment status and not required to make payments.

Our collection policies for Private Education Loans allow for periods of nonpayment for certain borrowers requesting an extended grace period upon leaving school or experiencing temporary difficulty meeting payment obligations. This is referred to as forbearance and is considered in estimating the allowance for credit losses.

As part of concluding on the adequacy of the allowance for credit losses for Private Education Loans, we review key allowance and loan metrics. The most relevant of these metrics considered are the allowance as a percentage of ending total loans, delinquency percentages, and forbearance percentages.

We consider a Private Education Loan to be delinquent if the borrower has not made a required payment prior to the 31st day after such payment was contractually due.

Troubled Debt Restructurings ("TDRs")

Troubled Debt Restructurings (“TDRs”) - 2021 and 2020

In estimating the expected defaults for our Private Education Loans that are considered TDRs, we follow the same discounted cash flow process described above but use the historical loss rates related to past TDR loans. The appropriate gross loss rates are determined for each individual loan by evaluating loan maturity, risk characteristics, and macroeconomic conditions.

The allowance for our TDR portfolio is included in our overall allowance for Private Education Loans. Our TDR portfolio is comprised mostly of loans with interest rate reductions and loans with forbearance usage greater than three months, as further described below.

We adjust the terms of loans for certain borrowers when we believe such changes will help our customers manage their student loan obligations, achieve better student outcomes, and increase the collectability of the loans. These changes generally take the form of a temporary forbearance of payments, a temporary interest rate reduction, a temporary interest rate reduction with a permanent extension of the loan term, and/or a short-term extended repayment alternative. When we give a borrower facing financial difficulty an interest rate reduction, we temporarily reduce the rate (currently to 4.0 percent) for a two-year period and, in the vast majority of cases, permanently extend the final maturity of the loan. The combination of these two loan term changes helps reduce the monthly payment due from the borrower and increases the likelihood the borrower will remain current during the interest rate modification period as well as when the loan returns to its original contractual interest rate.

We classify a loan as a TDR due to forbearance using a two-step process. The first step is to identify a loan that was in full principal and interest repayment status and received more than three months of forbearance in a 24-month period; however, during the first nine months after a loan had entered full principal and interest repayment status, we do not count up to the first six months of forbearance received during that period against the three-month policy limit. The second step is to evaluate the creditworthiness of the loan by examining its most recent refreshed FICO score. Loans that have met the criteria in the first test and have a FICO score above a certain threshold (based on the most recent quarterly FICO

score refresh) will not be classified as TDRs. Loans that have met the criteria in the first test and have a FICO score under the threshold (based on the most recent quarterly FICO score refresh) will be classified as TDRs.

A loan also becomes a TDR when it is modified to reduce the interest rate on the loan (regardless of when such modification occurs and/or whether such interest rate reduction is temporary). Once a loan qualifies for TDR status, it remains a TDR for allowance purposes for the remainder of its life. About half our loans that are considered TDRs involve a temporary forbearance of payments and do not change the contractual interest rate of the loan. As of both December 31, 2021 and 2020, approximately 47 percent of TDRs were classified as such due to their forbearance status. For additional information, see Note 7, “Allowance for Credit Losses.”

On March 27, 2020, then President Trump signed into law the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), which, among other things, allows us to (i) elect to suspend the requirements under GAAP for loan modifications related to COVID-19 that would otherwise be categorized as TDRs, and (ii) suspend any determination of a loan modified as a result of the effects of COVID-19 as being a TDR, including impairment for accounting purposes. Furthermore, on December 27, 2020, the Consolidated Appropriations Act, 2021 (the “CAA”) was signed into law. The CAA provides for additional COVID-19 focused relief and extends certain provisions of the CARES Act.

We have elected to suspend TDR accounting for both forbearance and interest rate modifications of loans that occur as a result of COVID-19 for the applicable period of the CARES Act and CAA relief. The relief from TDR guidance applies to modifications of loans that were not more than 30 days past due as of December 31, 2019, and that occur during the period beginning on March 1, 2020, and ending on the earlier of (i) sixty days after the date on which the national emergency related to the COVID-19 outbreak is terminated, or (ii) January 1, 2022. We are continuing to apply TDR accounting to those loans that were more than 30 days past due as of December 31, 2019 and were subsequently modified.

Off-Balance Sheet Exposure for Contractual Loan Commitments

Off-Balance Sheet Exposure for Contractual Loan Commitments - 2021 and 2020

When we approve a Private Education Loan at the beginning of an academic year, that approval may cover the borrowing for the entire academic year. As such, we do not always disburse the full amount of the loan at the time of such approval, but instead have a commitment to fund a portion of the loan at a later date (usually the start of the second semester or subsequent trimesters). We estimate expected credit losses over the contractual period in which we are exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by us. The discounted cash flow approach described above includes expected future contractual disbursements. The portion of the allowance for credit losses related to future disbursements is shown as a liability on the face of the balance sheet, and related provision for credit losses is reflected on the income statement.

Uncollectible Interest - 2021 and 2020

The majority of the total accrued interest receivable on our Private Education Loan portfolio represents accrued interest on deferred loans where no payments are due while the borrower is in school and on fixed-pay loans where the borrower makes a $25 monthly payment that is smaller than the interest accrued on the loan in that month. The accrued interest on these loans will be capitalized and increase the unpaid principal balance of the loans when the borrower exits the grace period after separation from school. The discounted cash flow approach described above considers both the collectability of principal as well as this portion of accrued interest that is expected to capitalize to the balance of the loan. Therefore, the allowance for this portion of accrued interest balance is included in our allowance for credit losses. The discounted cash flow approach does not consider interest accrued on loans that are in a full principal and interest repayment status or in interest-only repayment status. We separately capture the amount of expected uncollectible interest associated with these loans using historical experience to estimate the uncollectible interest for the next four months at each period-end date. This amount is recorded as a reduction of interest income. Accrued interest receivable is separately disclosed on the face of the balance sheet.

Allowance For Credit Card Loans

Allowance for Credit Card Loans - 2021 and 2020

We use the gross loss approach when estimating the allowance for credit losses for our Credit Card portfolio. Because our Credit Card portfolio is new and we do not have sufficient historical loss experience, we use estimated loss rates reported by other financial institutions to estimate our allowance for credit losses for Credit Cards, net of expected recoveries. In addition, we use a model that utilizes purchased credit card information with risk characteristics similar to those of our own portfolio as a challenger model. We then consider any qualitative factors that may change our future expectations of losses.

As all of our Credit Card loans are unconditionally cancelable by us, the issuer, we do not record any estimate of credit losses for unused portions of our Credit Card commitments.

Deposits

Our retail deposit accounts are principally certificates of deposit (“CDs”), money market deposit accounts (“MMDAs”), and high-yield savings (“HYS”) accounts. CDs are accounts that have a stipulated maturity and interest rate. Retail CDs may be withdrawn early, but a penalty is assessed. MMDA and HYS accounts are both interest and non-interest bearing accounts that have no maturity or expiration date. For retail MMDA and HYS accounts, the depositor may be required to give written notice of any intended withdrawal not less than seven days before the withdrawal is made.

The Bank also includes brokered CDs in its funding base. Early withdrawal of brokered CDs is prohibited (except in the case of death or legal incapacity). Other deposit accounts include large interest-bearing omnibus accounts deposited in the Bank by commercial entities having custodial responsibilities for many underlying accounts. These omnibus accounts may be structured with or without fixed maturities, and may have fixed or variable interest rates.

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 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 consolidated 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.

Loan Interest Income

For all loans, including impaired loans (regardless of the delinquency status of the impaired loans), classified as held for investment, we recognize interest income as earned, adjusted for the amortization of deferred direct origination and acquisition costs. Deferred fees or costs are required to be recognized as yield adjustments over the life of the related loans and are recognized by the interest method. The objective of the interest method is to arrive at periodic interest income (including recognition of fees and costs) at a constant effective yield on the net investment in the receivable (i.e., the principal amount of the receivable adjusted by unamortized fees or costs, purchase premium or discount, and any hedging activity—these unamortized costs will collectively be referred to as “basis adjustments”). The difference between the periodic interest income so determined and the interest income determined by applying the stated interest rate to the outstanding principal amount of the receivable is the amount of periodic amortization of deferred direct origination and acquisition costs.

For the amortization of the basis adjustments, we determine the constant effective yield necessary to apply the interest method based upon the contractual terms of the loan contract, with no consideration given to expected prepayments.

For fixed-rate loans, when a prepayment occurs the unamortized balance of the basis adjustments is adjusted so that future amortization (based upon the contractual terms of the loan) will result in a constant effective yield equal to the original effective interest rate. Prepayments do not result in a change in the effective interest rate of the loan. We determine the contractual payments on a pool basis; as such, when a prepayment occurs, future contractual payments will be determined assuming the pool will make smaller payments through the original term of the contract. The adjustment to the unamortized basis adjustment balance is recorded in interest income.

For variable-rate loans, the effective interest rate at the time of origination is the loan’s effective interest rate assuming all future contractual payments. The effective interest rate remains the same for that loan until the loan rate changes. If there is no prepayment and no change in the stated interest rate, the periodic amortization of the basis adjustments is equal to the difference between the effective interest rate multiplied by the book basis and the contractual interest due. We determine the contractual payments on a pool basis; as such, when a prepayment occurs, future contractual payments will be determined assuming the pool will make smaller payments through the original term of the contract. The adjustment to the unamortized basis adjustment balance is recorded in interest income.

When the interest rate on a variable-rate loan changes, the effective interest rate is recalculated using the same methodology described in the previous paragraph; however, the future contractual payments are changed to reflect the new interest rate. There is no forecasting of future expected changes in interest rates. The accounting basis used to determine the effective interest rate of the cash flows is equal to the balances of the unpaid principal balance and unamortized basis adjustments at the time of the rate change.

We also pay to the U.S. Department of Education (the “DOE”) an annual 105 basis point Consolidation Loan Rebate Fee on FFELP consolidation loans, which is netted against loan interest income. Additionally, interest earned on education loans reflects potential non-payment adjustments in accordance with our uncollectible interest recognition policy. We do not amortize any adjustments to the basis of loans when they are classified as held-for-sale.

With the adoption of CECL on January 1, 2020, we continue to analyze the collectability of accrued interest associated with loans not currently in full principal and interest repayment status or interest-only repayment status as discussed above; however, we have changed the recognition of the allowance for this portion of uncollectible interest (amounts to be capitalized after separation from school and the expiration of the grace period) to the provisions for credit losses from our historical practice of recording it as a reduction of interest income, as well as classifying this allowance as part of our allowance for credit losses as opposed to our historical practice of recording it as a reduction of accrued interest income receivable.

The allowance for the portion of uncollectible interest on loans making full interest payments will continue to be recorded as a reduction of interest income. As we maintain an allowance for uncollectible interest on loans making full interest payments and an allowance for credit losses for the interest on loans where all, or a portion of the interest, will be capitalized in the future, we do not place loans in nonaccrual status prior to charge-off. At December 31, 2021 and 2020, we had no loans in nonaccrual status.

We recognize certain fee income (primarily late fees) on all loans when earned according to the contractual provisions of the promissory notes, as well as our expectation of collectability. Fee income is recorded when earned in “other non-interest income” in the accompanying consolidated statements of income.

Interest Expense

Interest ExpenseInterest expense is based upon contractual interest rates adjusted for the amortization of issuance costs. We incur interest expense on interest-bearing deposits comprised of non-maturity savings deposits, brokered and retail CDs, and brokered and retail MMDAs, as well as on unsecured and secured financings. Interest expense is recognized when amounts are contractually due to deposit and debt holders and is adjusted for net payments/receipts related to interest rate swap agreements that qualify and are designated hedges of interest-bearing liabilities. 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. We incur certain fees related to our Private Education Loan multi-lender secured borrowing facility (the “Secured Borrowing Facility”), including an unused Secured Borrowing Facility fee, and also incur fees related to our term asset-backed securities (“ABS”). These fees are included in interest expense.

Gains on Sale of Loans, Net

Gains on Sale of Loans, NetWe may participate and sell loans to third-parties and affiliates, including entities that were related parties prior to the Spin-Off. These sales may occur through whole loan sales or securitization transactions that qualify for sales treatment. If a transfer of loans qualifies as a sale, we derecognize the loan and recognize a gain or loss as the difference between the carry basis of the loan sold and liabilities retained and the compensation received. We recognize the results of a transfer of loans based upon the settlement date of the transaction. These loans were initially recorded as held for investment and were transferred to held-for-sale immediately prior to sale or securitization.

Other Income

Included in other income are late fees on both Private Education Loans and FFELP Loans, which we recognize when the cash has been received, fees related to our Credit Card program, income for servicing private student loans for third-parties, and changes to our tax indemnification receivable from Navient.

Our former Upromise subsidiary had a number of programs that encouraged consumers to save for the cost of college education. We had established a consumer savings network, which was designed to promote college savings by consumers who were members of this program by encouraging them to purchase goods and services from the merchants that participated in the program. Participating merchants generally paid Upromise fees based on member purchase volume, either online or in stores, depending on the contractual arrangement with the merchant. We recognized revenue as marketing and administrative services were rendered, based upon contractually determined rates and member purchase volumes. On May 31, 2020, we sold our Upromise subsidiary to a third party, resulting in the loss of revenue from that business for the second half of 2020.

Securitization Accounting

Our securitization transactions use a two-step structure with a special purpose entity VIE that legally isolates the transferred assets from us in the event of bankruptcy or receivership. 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. 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. We are considered the primary beneficiary if we have both: (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance; and (ii) the obligation to absorb losses or receive benefits of the entity that could potentially be significant to the VIE. There can be considerable judgment as it relates to determining the primary beneficiary of the VIEs. There are no “bright line” tests. Rather, the assessment of who has the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and who has the obligation to absorb losses or receive benefits of the entity that could potentially be significant to the VIE can be very qualitative and judgmental in nature. If we are the primary beneficiary, then no gain or loss is recognized.

We have determined that as the servicer of Sallie Mae securitization trusts, we meet the first primary beneficiary criterion because we have the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance.

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;

•Our responsibilities relative to representation and warranty violations; and

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

In 2021 and 2020, we executed several secured financing transactions. Based upon our relationships with these securitizations, we believe the consolidation assessment is straightforward. We consolidated our secured financing transactions because either we did not meet the accounting criterion for sales treatment or we determined we were the primary beneficiary of the VIE because we retained (i) the residual interest in the securitization and therefore had the obligation to absorb losses or receive benefits of the entity that could potentially be significant to the VIE, as well as (ii) the power to direct the activities of the VIE in our role as servicer.

The investors in our securitization trusts have no recourse to our other assets should there be a failure of the trust to pay when due. Generally, the only recourse the securitization trusts have to us is in the event we breach a seller representation or warranty or our duties as master servicer and servicer, in which event we are obligated to repurchase the related loans from the trust.

From time to time, we also engage in certain transactions that are not consolidated on our balance sheet due to the transaction having met the criterion for sales treatment. In these transactions, we remove loans from our consolidated balance sheet and recognize any assets retained and liabilities assumed at fair value, and record a gain or loss on the transferred loans. Our continuing involvement in these securitization transactions mainly consists of acting as the primary servicer and holding certain retained interests. We provide additional information regarding these types of activities in Note 11, “Borrowings — Unconsolidated VIEs.”

Derivative Accounting

We account for our derivatives, consisting of interest rate swaps, at fair value on the consolidated balance sheets as either an asset or liability. Derivative positions are recorded as net positions by counterparty based on master netting arrangements (see Note 12, “Derivative Financial Instruments”), exclusive of accrued interest and cash collateral held or pledged. The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) requires all standardized derivatives, including most interest rate swaps, to be submitted for clearing to central counterparties to reduce counterparty risk. Two of the central counterparties we use are the Chicago Mercantile Exchange (the “CME”) and the London Clearing House (the “LCH”). All variation margin payments on derivatives cleared through the CME and LCH are accounted for as legal settlement. As of December 31, 2021, $5.2 billion notional of our derivative contracts were cleared on the CME and $0.3 billion were cleared on the LCH. The derivative contracts cleared through the CME and LCH represent 94.4 percent and 5.6 percent, respectively, of our total notional derivative contracts of $5.5 billion at December 31, 2021.

For derivatives cleared through the CME and LCH, the net gain (loss) position includes the variation margin amounts as settlement of the derivative and not collateral against the fair value of the derivative. The amount of variation margin included as settlement as of December 31, 2021 was $(72) million and $8 million for the CME and LCH, respectively. Changes in fair value for derivatives not designated as hedging instruments are presented as realized gains (losses).

We determine the fair value for our derivative contracts primarily using pricing models that consider current market conditions and the contractual terms of the derivative contracts. These pricing models consider interest rates, time value, forward interest rate curves, and volatility factors. Inputs are generally from active financial markets.

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 fair value. Our derivative instruments are classified and accounted for by us as fair value hedges, cash flow hedges, and trading hedges.

Each derivative is designated to a specific (or pool of) liability(ies) on the consolidated balance sheets, and is designated as either a “fair value” hedge or a “cash flow” hedge. Fair value hedges are designed to hedge our exposure to the changes in fair value of a fixed-rate liability. For effective fair value hedges, both the hedge and the hedged item (for the risk being hedged) are recorded at fair value with any difference reflecting ineffectiveness recorded immediately in the consolidated statements of income. Cash flow hedges are designed to hedge our exposure to variability in cash flows related to variable-rate deposits. The assessment of the hedge’s effectiveness is performed at inception and on an ongoing basis, using regression testing. For hedges of a pool of 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 fair value of the derivative with no offsetting amount from the hedged item since the last time it was effective. If it is also determined the hedge will not be effective in the future, we discontinue the hedge accounting prospectively and begin amortization of any basis adjustments that exist related to the hedged item.

On March 12, 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (“Topic 848”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” On January 7, 2021, the FASB issued ASU No. 2021-01, “Reference Rate Reform (“Topic 848”): Scope” that clarified the scope of Topic 848. Topic 848 contains temporary optional expedients and exceptions for applying GAAP to contract modifications, hedging relationships, and other transactions affected by reference rate reform.

Our derivative portfolio is made up of interest rate swaps that are centrally cleared through either the CME or the LCH. On October 16, 2020, both the CME and the LCH changed the price alignment interest and discount rate applied when valuing these transactions to the Secured Overnight Financing rate (“SOFR”). The ISDA 2020 LIBOR Fallbacks Protocol (the “ISDA Fallback Protocol”) was made available for adherence on October 23, 2020, with an effective date of January 25, 2021. Once adhered to by both counterparties in a bilateral relationship and the effective date is reached, the ISDA Fallback Protocol represents a change to the contractual terms of derivatives governed by each respective ISDA agreement between the Company and a derivative counterparty. We have elected the option provided in Topic 848 to not reassess previous accounting determinations as well as the option to not dedesignate a hedging relationship due to a current or future change in a critical or contractual term related to reference rate reform, including changes in the discount rate.

As our liabilities may begin to use alternatives to LIBOR before LIBOR is no longer published, for cash flow hedges of forecasted LIBOR based payments, we have elected the expedient offered in Topic 848 to disregard the potential change in the designated hedged interest rate risk that may occur because of reference rate reform when we assesses whether the hedged forecasted transactions are probable, in accordance with the requirements of “Derivatives and Hedging” Topic 815. We have also elected the expedient provided by Topic 848 to assume the reference rate will not be replaced for the remainder of the hedging relationship when assessing hedge effectiveness.

Topic 848 allows for different elections to be made at different points in time. We intend to reassess our elections of optional expedients and exceptions included within Topic 848 when changes or additions are necessary.

Stock-Based Compensation

Stock-Based CompensationWe recognize stock-based compensation cost in our consolidated statements of income using the fair value 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. We do not apply a forfeiture rate to our stock-based compensation expense, but rather record forfeitures when they occur. We record all excess tax benefits/deficiencies related to the settlement of employee stock-based compensation to the income tax expense line item on our consolidated statements of income.

Restructuring Activities

During the third quarter of 2020, we initiated a restructuring program to reduce costs and improve operating efficiencies by better aligning our organizational structure with our new corporate strategic imperatives. In conjunction with these restructuring plans, involuntary benefit arrangements, and 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. Restructuring expenses of $26 million were recorded in the year ended December 31, 2020. Of that total, $20 million related to severance benefits and $6 million related to other related costs, primarily legal and consulting fees. We recorded $1 million in additional restructuring expenses in the year ended December 31, 2021. There were no restructuring expenses recorded in the year ended December 31, 2019.

We sponsor employee severance plans that provide severance benefits in the event of termination of our full-time employees and part-time employees who work at least 24 hours per week. The severance plans establish 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 plans. The benefits payable under the severance plans relate to past service. Accordingly, we recognize severance costs to be paid pursuant to the severance plans 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, were incurred during the year ended December 31, 2020, as a direct result of our restructuring initiative. Accordingly, such costs are classified as restructuring expenses in the accompanying consolidated statements of income. We finalized this restructuring plan in 2020.

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 when applicable, 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.

An uncertain 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 consolidated financial statements is the largest amount of benefit that is more than 50 percent likely of being sustained upon ultimate settlement of the uncertain tax position. We recognize interest and penalties related to unrecognized tax benefits in income tax expense (benefit).

In connection with the Spin-Off, we recorded a liability related to uncertain tax positions of $27 million for which we are indemnified by Navient. If there is an adjustment to the indemnified uncertain tax liability, an offsetting adjustment to the indemnification receivable will be recorded as pre-tax adjustment to other income in the income statement.

As of the date of the Spin-Off on April 30, 2014, we recorded liabilities related to deferred taxes and uncertain tax positions and an indemnification receivable of $291 million. As of December 31, 2021, with respect to those amounts recorded at the Spin-Off, the remaining liability balance is $5 million (related to uncertain tax positions) and the remaining indemnification receivable balance is $5 million (related to uncertain tax positions).
