1. Significant Accounting Policies
Basis of Presentation
The accompanying unaudited, consolidated financial statements of SLM Corporation (“Sallie Mae,” “SLM,” the “Company,” “we,” or “us”) have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information. Accordingly, they do not include all the information and footnotes required by GAAP for complete consolidated financial statements. 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. In the opinion of management, all adjustments considered necessary for a fair statement of the results for the interim periods have been included. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Operating results for the three and six months ended June 30, 2018 are not necessarily indicative of the results for the year ending December 31, 2018 or for any other period. These unaudited financial statements should be read in conjunction with the audited financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2017 (the “2017 Form 10-K”).
Consolidation
The consolidated financial statements include the accounts of the Company 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: (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.
Recently Issued and Adopted Accounting Pronouncements
In November 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash.” Whereas restricted cash balances have traditionally been excluded from the statement of cash flows, this ASU requires restricted cash and restricted cash equivalents to be included within the beginning and ending totals of cash, cash equivalents and restricted cash presented on the statement of cash flows for all periods presented. Restricted cash and restricted cash equivalent inflows and outflows with external parties are required to be classified within the operating, investing, and/or financing activity sections of the statement of cash flows, whereas transfers between cash and cash equivalents and restricted cash and restricted cash equivalents should no longer be presented on the statement of cash flows. ASU No. 2016-18 also requires (a) the nature of the restrictions to be disclosed to help provide information about the sources and uses of these balances during a reporting period and (b) a reconciliation of the cash, cash equivalents and restricted cash totals on the statement of cash flows to the related balance sheet line items when cash, cash equivalents, and restricted cash are presented in more than one line item on the balance sheet. The reconciliation can be presented either on the face of the statement of cash flows or in the notes to the financial statements and must be provided for each period that a balance sheet is presented. We adopted the new accounting pronouncement on January 1, 2018, and the adoption did not have a material impact to our statement of cash flows.
In February 2018, the FASB issued ASU No. 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the tax law and tax rate changes under the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) enacted on December 22, 2017. Under the Tax Act, deferred taxes were adjusted to reflect the reduction of the historical corporate income tax rate to the newly enacted corporate income tax rate, which left the tax effects on items within accumulated other comprehensive income stranded at an

inappropriate tax rate. This guidance is effective for fiscal years beginning after December 15, 2018, and for interim periods within those fiscal years, with early adoption permitted. We adopted this standard effective January 1, 2018 and recorded a $0.6 million reclass from accumulated other comprehensive income to retained earnings in the first quarter of 2018.

Our investment portfolio is comprised primarily of mortgage-backed securities issued by Ginnie Mae, Fannie Mae and Freddie Mac, with amortized costs of $72 million, $49 million, and $46 million, respectively, at June 30, 2018. We own these securities to meet our requirements under the Community Reinvestment Act. In the second quarter of 2018, we elected to sell nine securities totaling $41 million to better align the portfolio with the Community Reinvestment Act requirements, and we recognized a $2 million loss upon the sale of those securities. As of June 30, 2018, 75 of the 84 separate mortgage-backed securities in our investment portfolio had unrealized losses, and 35 of the 75 securities in a net loss position were issued under Ginnie Mae programs that carry a full faith and credit guarantee from the U.S. Government. The remaining securities in a net loss position carry a principal and interest guarantee by Fannie Mae or Freddie Mac, respectively. We have the ability and the intent to hold these securities for a period of time sufficient for the market price to recover to at least the adjusted amortized cost of the security. As of December 31, 2017, 62 of the 92 separate mortgage-backed securities in our investment portfolio had unrealized losses, and 31 of the 62 securities in a net loss position were issued under Ginnie Mae programs that carry a full faith and credit guarantee from the U.S. Government. The remainder carried a principal and interest guarantee by Fannie Mae or Freddie Mac, respectively.
We also invest in Utah Housing Corporation bonds for the purpose of complying with the Community Reinvestment Act. These bonds are Aa3 rated by Moody’s Investors Service. The amortized cost of the investment on the consolidated balance sheet at June 30, 2018 and December 31, 2017 was $19 million and $20 million, respectively. We have the intent and ability to hold these bonds for a period of time sufficient for the market price to recover to at least the adjusted amortized cost of the security.

As of June 30, 2018, the amortized cost and fair value of securities, by contractual maturities, are summarized below. Contractual maturities versus actual maturities may differ due to the effect of prepayments.

The mortgage-backed securities have been pledged to the Federal Reserve Bank (the “FRB”) as collateral against any advances and accrued interest under the Primary Credit lending program sponsored by the FRB. We had $161 million and $218 million par value of mortgage-backed securities pledged to this borrowing facility at June 30, 2018 and December 31, 2017, respectively, as discussed further in Note 6, “Borrowings.”
3. Loans Held for Investment
Loans held for investment consist of Private Education Loans, FFELP Loans and Personal Loans. We use “Private Education Loans” to mean education loans to students or their families that are not made, insured or guaranteed by any state or federal government. Private Education Loans do not include loans insured or guaranteed under the previously existing Federal Family Education Loan Program (“FFELP”). We use “Personal Loans” to mean those unsecured loans to individuals that may be used for non-educational purposes. We began acquiring Personal Loans from third parties in the fourth quarter of 2016 and originating Personal Loans in the first quarter of 2018.
Our Private Education Loans are made largely to bridge the gap between the cost of higher education and the amount funded through financial aid, government loans and customers’ resources. Private Education Loans bear the full credit risk of the customer. We manage this risk through risk-performance underwriting strategies and qualified cosigners. Private Education Loans may be fixed rate or may carry a variable interest rate indexed to LIBOR. As of June 30, 2018, and December 31, 2017, 73 percent and 77 percent, respectively, of all of our Private Education Loans were indexed to LIBOR. We provide incentives for customers to include a cosigner on the loan, and the vast majority of loans in our portfolio are cosigned. We also encourage customers to make payments while in school.
In connection with the separation of Navient Corporation (“Navient”) from SLM (the “Spin-Off”), we retained the right to require Navient to purchase delinquent loans (at fair value) when the borrower has a lending relationship with both us and Navient (“Split Loans”). In the second quarter of 2018, we sold our remaining $43 million portfolio of Split Loans (both current and non-current loans) to Navient and recognized a net gain of $2 million.
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 on or after July 1, 2006, we receive 97 percent reimbursement on all qualifying claims. For loans disbursed after October 1, 1993, and before July 1, 2006, we receive 98 percent reimbursement on all qualifying claims. For loans disbursed prior to October 1, 1993, we receive 100 percent reimbursement on all qualifying claims.

4. Allowance for Loan Losses
Our provision for credit losses represents the periodic expense of maintaining an allowance sufficient to absorb incurred probable losses in the held-for-investment loan portfolios. The evaluation of the allowance for loan losses is inherently subjective, as it requires material estimates that may be susceptible to significant changes. We believe the allowance for loan losses is appropriate to cover probable losses incurred in the loan portfolios.

Troubled Debt Restructurings (“TDRs”)
All of our loans are collectively assessed for impairment, except for loans classified as TDRs (where we conduct individual assessments of impairment). We modify the terms of loans for certain borrowers when we believe such modifications may increase the ability and willingness of a borrower 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. The majority of our loans that are considered TDRs involve a temporary forbearance of payments and do not change the contractual interest rate of the loan. Once a loan qualifies for TDR status, it remains a TDR for allowance purposes for the remainder of its life. As of June 30, 2018, and December 31, 2017, approximately 61 percent and 66 percent, respectively, of TDRs were classified as such due to their forbearance status. For additional information, see Note 6, “Allowance for Loan Losses” in our 2017 Form 10-K.
Within the Private Education Loan portfolio, loans greater than 90 days past due are considered to be nonperforming. FFELP Loans are at least 97 percent guaranteed as to their principal and accrued interest by the federal government in the event of default and, therefore, we do not deem FFELP Loans as nonperforming from a credit risk perspective at any point in their life cycle prior to claim payment and continue to accrue interest on those loans through the date of claim.
At June 30, 2018 and December 31, 2017, all TDR loans had a related allowance recorded. The following table provides the recorded investment, unpaid principal balance and related allowance for our TDR loans.

|  | Recorded Investment |  | Unpaid Principal Balance |  | Allowance

Private Education Loan Key Credit Quality Indicators
FFELP Loans are at least 97 percent insured and guaranteed as to their principal and accrued interest in the event of default; therefore, there are no key credit quality indicators associated with FFELP Loans.
For Private Education Loans, the key credit quality indicators are FICO scores, the existence of a cosigner, the loan status and loan seasoning. The FICO scores are assessed at original approval and periodically refreshed/updated through the loan’s term. The following table highlights the gross principal balance of our Private Education Loan portfolio stratified by key credit quality indicators.

Total deposits |  | $ | 16,745,957 |  |  | $ | 15,505,383 |  |

Our total deposits of $16.7 billion were comprised of $8.7 billion in brokered deposits and $8.0 billion in retail and other deposits at June 30, 2018, compared to total deposits of $15.5 billion, which were comprised of $8.2 billion in brokered deposits and $7.3 billion in retail and other deposits, at December 31, 2017.
Interest bearing deposits as of June 30, 2018 and December 31, 2017 consisted of retail and brokered non-maturity savings deposits, retail and brokered non-maturity money market deposits (“MMDAs”) and retail and brokered certificates of deposit (“CDs”). Interest bearing deposits include deposits from Educational 529 and Health Savings plans that diversify our funding sources and additional deposits we consider to be core. These and other large omnibus accounts, aggregating the deposits of many individual depositors, represented $5.7 billion of our deposit total as of June 30, 2018, compared with $5.5 billion at December 31, 2017.
Some of our deposit products are serviced by third-party providers. Placement fees associated with the brokered CDs are amortized into interest expense using the effective interest rate method. We recognized placement fee expense of $3 million and $2 million in the three months ended June 30, 2018 and 2017, respectively, and placement fee expense of $6 million and $4 million in the six months ended June 30, 2018 and 2017, respectively. Fees paid to third-party brokers related to brokered CDs were $12 million and $3 million for the three months ended June 30, 2018 and 2017, respectively, and fees paid to third-party brokers related to brokered CDs were $19 million and $5 million for the six months ended June 30, 2018 and 2017, respectively.

Short-term Borrowings
Asset-Backed Commercial Paper Funding Facility
On February 21, 2018, we amended and extended the maturity of our $750 million ABCP Facility. We hold 100 percent of the residual interest in the ABCP Facility trust. Under the amended ABCP Facility, we incur financing costs of between 0.35 percent and 0.45 percent on unused borrowing capacity and approximately 3-month LIBOR plus 0.85 percent on outstandings. The amended ABCP Facility extends the revolving period, during which we may borrow, repay and reborrow funds, until February 20, 2019. The scheduled amortization period, during which amounts outstanding under the ABCP Facility must be repaid, ends on February 20, 2020 (or earlier, if certain material adverse events occur). At both June 30, 2018 and December 31, 2017, there were no borrowings outstanding under the ABCP Facility. We expect to amend and extend the ABCP Facility on an annual basis.

____
(1) Other assets primarily represent accrued interest receivable.
Other Borrowing Sources
We maintain discretionary uncommitted Federal Funds lines of credit with various correspondent banks, which totaled $125 million at June 30, 2018. The interest rate we are charged on these lines of credit is priced at Fed Funds plus a spread at the time of borrowing and is payable daily. We did not utilize these lines of credit in the six months ended June 30, 2018 or in the year ended December 31, 2017.
We established an account at the FRB to meet eligibility requirements for access to the Primary Credit borrowing facility at the FRB’s Discount Window (the “Window”). The Primary Credit borrowing facility is a lending program available to depository institutions that are in generally sound financial condition. All borrowings at the Window must be fully collateralized. We can pledge to the FRB asset-backed and mortgage-backed securities, as well as FFELP Loans and Private Education Loans, as collateral for borrowings at the Window. Generally, collateral value is assigned based on the estimated fair value of the pledged assets. At June 30, 2018 and December 31, 2017, the value of our pledged collateral at the FRB totaled $2.5 billion and $2.6 billion, respectively. The interest rate charged to us is the discount rate set by the FRB. We did not utilize this facility in the six months ended June 30, 2018 or in the year ended December 31, 2017.

7. Derivative Financial Instruments
We maintain an overall interest rate risk management strategy that incorporates the use of derivative instruments to reduce 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 or liabilities, so any adverse impacts related to movements in interest rates are managed within low to moderate limits. As a result of interest rate fluctuations, hedged balance sheet positions will appreciate or depreciate in market value or create variability in cash flows. Income or loss on the derivative instruments linked to the hedged item will generally offset the effect of this unrealized appreciation or depreciation or volatility in cash flows for the period the item is being hedged. We view this strategy as a prudent management of interest rate risk. Please refer to Note 11, “Derivative Financial Instruments” in our 2017 Form 10-K for a full discussion of our risk management strategy.
Title VII of 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 (“CME”) and the London Clearing House (“LCH”). The CME and the LCH made amendments to their respective rules that resulted in the prospective accounting treatment of certain daily variation margin payments being considered as the legal settlement of the outstanding exposure of the derivative instead of the posting of collateral. The CME rule changes, which became effective in January 2017, and the LCH rule changes, which became effective in January 2018, result in all variation margin payments on derivatives cleared through the CME and LCH being accounted for as legal settlement. As of June 30, 2018, $5.9 billion notional of our derivative contracts were cleared on the CME and $0.6 billion were cleared on the LCH. The derivative contracts cleared through the CME and LCH represent 90.3 percent and 9.7 percent, respectively, of our total notional derivative contracts of $6.5 billion at June 30, 2018.
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. Interest income (expense) related to variation margin on derivatives that are not designated as hedging instruments or are designated as fair value relationships is recognized as a gain (loss) rather than as interest income (expense). Changes in fair value for derivatives not designated as hedging instruments will be presented as realized gains (losses).
Our exposure is limited to the value of the derivative contracts in a gain position less any collateral held and plus any collateral posted. When there is a net negative exposure, we consider our exposure to the counterparty to be zero. At June 30, 2018 and December 31, 2017, we had a net positive exposure (derivative gain positions to us, less collateral held by us and plus collateral posted with counterparties) related to derivatives of $30 million and $20 million, respectively.

10. 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” in our 2017 Form 10-K.
During the six months ended June 30, 2018, there were no significant transfers of financial instruments between levels or changes in our methodology or assumptions used to value our financial instruments.
The following table summarizes the valuation of our financial instruments that are marked to fair value on a recurring basis.

11. Arrangements with Navient Corporation
In connection with the Spin-Off, we entered into a separation and distribution agreement (the “Separation and Distribution Agreement”) and other ancillary agreements with Navient. Please refer to Note 16, “Arrangements with Navient Corporation” in our 2017 Form 10-K for a full discussion of these agreements.
Indemnification Obligations
Navient is responsible for, and has agreed to indemnify us against, all claims, actions, damages, losses or expenses that may arise from the conduct of all activities of pre-Spin-Off SLM Corporation (“pre-Spin-Off SLM”) occurring prior to the Spin-Off other than those specifically excluded in the Separation and Distribution Agreement. Some significant examples of the types of indemnification obligations Navient has under the Separation and Distribution Agreement and related ancillary agreements include:

• | Navient will indemnify the Company and Sallie Mae Bank, a Utah industrial bank subsidiary of the Company (the “Bank”), for any liabilities, costs or expenses they may incur arising from any action or threatened action related to the servicing, operations and collections activities of pre-Spin-Off SLM and its subsidiaries with respect to Private Education Loans and FFELP Loans that were assets of the Bank or Navient at the time of the Spin-Off; provided that written notice was provided to Navient on or prior to April 30, 2017, the third anniversary date of the Spin-Off. Navient will not indemnify for changes in law or changes in prior existing interpretations of law that occur on or after April 30, 2014.

• | Pursuant to a tax sharing agreement, Navient has agreed to indemnify us for $283 million in deferred taxes that we are legally responsible for but that relate to gains recognized by our predecessor on debt repurchases made prior to the Spin-Off. The remaining amount of this indemnification at June 30, 2018 was $18 million. In connection with the Spin-Off, we also recorded a liability related to uncertain tax positions of $27 million for which we are indemnified by Navient. As of June 30, 2018, the remaining balance of the indemnification receivable related to those uncertain tax positions was $26 million. In addition, we believe we are indemnified by Navient for uncertain tax positions relating to historical transactions among entities that are now subsidiaries of Navient that should have been recorded at the time of the Spin-Off. The remaining balance of the indemnification receivable related to those uncertain tax positions was $110 million at June 30, 2018.

Amended Loan Participation and Purchase Agreement
Prior to the Spin-Off, the Bank sold substantially all of its Private Education Loans to several former affiliates, now subsidiaries of Navient (collectively, the “Purchasers”), pursuant to this agreement. This agreement predates the Spin-Off but was significantly amended and reduced in scope in connection with the Spin-Off. Post-Spin-Off, the Bank retained only the right to require the Purchasers to purchase Split Loans (at fair value) when the Split Loans either (1) are more than 90 days past due; (2) have been restructured; (3) have been granted a hardship forbearance or more than six months of administrative forbearance; or (4) have a borrower or cosigner who has filed for bankruptcy. In the second quarter of 2018, we sold our remaining $43 million portfolio of Split Loans (both current and non-current loans) to Navient and recognized a net gain of $2 million.

12. Regulatory Capital
The Bank is subject to various regulatory capital requirements administered by the FDIC and the Utah Department of Financial Institutions (the “UDFI”). Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material adverse effect on our business, results of operation and financial condition. Under the FDIC’s regulations implementing the Basel III capital framework (“U.S. Basel III”) and the regulatory framework for prompt corrective action, the Bank must meet specific capital standards that involve quantitative measures of its assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and its classification under the prompt corrective action framework are also subject to qualitative judgments by the regulators about components of capital, risk weightings and other factors.
The Bank is required to report regulatory capital and ratios in accordance with U.S. Basel III. Among other things, U.S. Basel III established Common Equity Tier 1 as a tier of capital, modified methods for calculating risk-weighted assets, introduced a capital conservation buffer (which is being phased in over several years), and revised the capital thresholds of the prompt corrective action framework, including the “well capitalized” standard.
“Well capitalized” regulatory requirements are the quantitative measures established by regulation to ensure capital adequacy. To qualify as “well capitalized,” the Bank must maintain minimum amounts and ratios (set forth in the table below) of Common Equity Tier 1, Tier 1 and Total capital to risk-weighted assets and of Tier 1 capital to average assets. The following capital amounts and ratios are based upon the Bank’s assets.

|  | Actual |  | “Well Capitalized” Regulatory Requirements
|  | Amount | Ratio |  | Amount |  | Ratio
As of June 30, 2018: |  |  |  |  |  |  |
Common Equity Tier 1 Capital (to Risk-Weighted Assets) |  | $ | 2,617,021 |  | 12.0 | % |  | $ | 1,417,350 |  | > | 6.5 | %
Tier 1 Capital (to Risk-Weighted Assets) |  | $ | 2,617,021 |  | 12.0 | % |  | $ | 1,744,431 |  | > | 8.0 | %
Total Capital (to Risk-Weighted Assets) |  | $ | 2,889,876 |  | 13.3 | % |  | $ | 2,180,539 |  | > | 10.0 | %
Tier 1 Capital (to Average Assets) |  | $ | 2,617,021 |  | 11.2 | % |  | $ | 1,164,750 |  | > | 5.0 | %
As of December 31, 2017: |  |  |  |  |  |  |
Common Equity Tier 1 Capital (to Risk-Weighted Assets) |  | $ | 2,350,081 |  | 11.9 | % |  | $ | 1,288,435 |  | > | 6.5 | %
Tier 1 Capital (to Risk-Weighted Assets) |  | $ | 2,350,081 |  | 11.9 | % |  | $ | 1,585,767 |  | > | 8.0 | %
Total Capital (to Risk-Weighted Assets) |  | $ | 2,597,926 |  | 13.1 | % |  | $ | 1,982,208 |  | > | 10.0 | %
Tier 1 Capital (to Average Assets) |  | $ | 2,350,081 |  | 11.0 | % |  | $ | 1,067,739 |  | > | 5.0 | %

Bank Dividends
The Bank is chartered under the laws of the State of Utah and its deposits are insured by the FDIC. The Bank’s ability to pay dividends is subject to the laws of Utah and the regulations of the FDIC. Generally, under Utah’s industrial bank laws and regulations as well as FDIC regulations, the Bank may pay dividends from its net profits without regulatory approval if, following the payment of the dividend, the Bank’s capital and surplus would not be impaired. The Bank paid no dividends for the six months ended June 30, 2018 and June 30, 2017.

13. Commitments, Contingencies and Guarantees
Commitments
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 at the start of the second semester or subsequent trimesters). At June 30, 2018, we had $1.7 billion of outstanding contractual loan commitments which we expect to fund during the remainder of the 2018/2019 academic year. At June 30, 2018, we had a $0.6 million reserve recorded in “Other Liabilities” to cover expected losses that may occur during the one-year loss emergence period on these unfunded commitments.
Contingencies
In the ordinary course of business, we and our subsidiaries are routinely 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 may be asserted against us and our subsidiaries.
It is common for the Company, our subsidiaries and affiliates to receive information and document requests and investigative demands from state attorneys general, legislative committees, and administrative agencies. These requests may be for informational or regulatory purposes and may relate to our business practices, the industries in which we operate, or other companies with whom we conduct business. Our practice has been and continues to be to cooperate with these bodies and be responsive to any such requests.
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, management does not believe there are loss contingencies, if any, arising from pending investigations, litigation or regulatory matters for which reserves should be established.

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

The following information is current as of July 24, 2018 (unless otherwise noted) and should be read in connection with SLM Corporation’s Annual Report on Form 10-K for the year ended December 31, 2017 (filed with the Securities and Exchange Commission (the “SEC”) on February 23, 2018) (the “2017 Form 10-K”), and subsequent reports filed with the SEC. Definitions for capitalized terms used in this report not defined herein can be found in the 2017 Form 10-K.
References in this Form 10-Q to “we,” “us,” “our,” “Sallie Mae,” “SLM” and the “Company” refer to SLM Corporation and its subsidiaries, except as otherwise indicated or unless the context otherwise requires.
This report contains “forward-looking” statements and information based on management’s current expectations as of the date of this report. Statements that are not historical facts, including statements about our beliefs, opinions or expectations and statements that assume or are dependent upon future events, are forward-looking statements. Forward-looking statements are subject to risks, uncertainties, assumptions and other factors that may cause actual results to be materially different from those reflected in such forward-looking statements. These factors include, among others, the risks and uncertainties set forth in Item 1A. “Risk Factors” and elsewhere in our 2017 Form 10-K and subsequent filings with the SEC; increases in financing costs; limits on liquidity; increases in costs associated with compliance with laws and regulations; failure to comply with consumer protection, banking and other laws; changes in accounting standards and the impact of related changes in significant accounting estimates; any adverse outcomes in any significant litigation to which we are a party; credit risk associated with our exposure to third-parties, including counterparties to our derivative transactions; and changes in the terms of education loans and the educational credit marketplace (including changes resulting from new laws and the implementation of existing laws). We could also be affected by, among other things: changes in our funding costs and availability; reductions to our credit ratings; cybersecurity incidents and cyberattacks and other failures or breaches of our operating systems or infrastructure, including those of third-party vendors; damage to our reputation; risks associated with restructuring initiatives, including failures to successfully implement cost-cutting programs and the adverse effects of such initiatives on our business; changes in the demand for educational financing or in financing preferences of lenders, educational institutions, students and their families; changes in law and regulations with respect to the student lending business and financial institutions generally; changes in banking rules and regulations, including increased capital requirements; increased competition from banks and other consumer lenders; the creditworthiness of our customers; changes in the general interest rate environment, including the rate relationships among relevant money-market instruments and those of our earning assets versus our funding arrangements; rates of prepayment on the loans that we make or acquire; changes in general economic conditions and our ability to successfully effectuate any acquisitions; and other strategic initiatives. The preparation of our consolidated financial statements also requires management to make certain estimates and assumptions, including estimates and assumptions about future events. These estimates or assumptions may prove to be incorrect. All forward-looking statements contained in this quarterly report on Form 10-Q are qualified by these cautionary statements and are made only as of the date of this report. We do not undertake any obligation to update or revise these forward-looking statements to conform such statements to actual results or changes in our expectations.
We report financial results on a GAAP basis and also provide certain non-GAAP core earnings performance measures. The difference between our “Core Earnings” and GAAP results for the periods presented were the unrealized, mark-to-market gains/losses on derivative contracts (excluding current period accruals on the derivative instruments), net of tax. These are recognized in GAAP, but not in “Core Earnings” results. We provide “Core Earnings” measures because this is what management uses when making management decisions regarding our performance and the allocation of corporate resources. Our “Core Earnings” are not defined terms within GAAP and may not be comparable to similarly titled measures reported by other companies. For additional information, see “Key Financial Measures” and “ ‘Core Earnings’ ” in this Form 10-Q for the quarter ended June 30, 2018 for a further discussion and a complete reconciliation between GAAP net income and “Core Earnings.”
Through this discussion and analysis, we intend to provide the reader with some narrative context for how our management views our consolidated financial statements, additional context within which to assess our operating results, and information on the quality and variability of our earnings, liquidity and cash flows.

(1) We calculate and report our non-GAAP operating efficiency ratio as the ratio of (a) the total non-interest expense numerator to (b) the net revenue denominator (which consists of the sum of net interest income, before provision for credit losses, and non-interest income, excluding any gains and losses on sales of loans and securities, net and the net impact of derivative accounting as defined in the “Core Earnings” adjustments to GAAP table set forth in this Form 10-Q.) We believe doing so provides useful information to investors because it is a measure used by our management team to monitor our effectiveness in managing operating expenses. Other companies may use similarly titled non-GAAP financial measures that are calculated differently from the way we calculate our ratio. Accordingly, our non-GAAP operating efficiency ratio may not be comparable to similar measures used by other companies.

Overview
The following discussion and analysis presents a review of our business and operations as of and for the three and six months ended June 30, 2018.
Key Financial Measures
Our operating results are primarily driven by net interest income from our Private Education Loan portfolio, provision expense for credit losses, and operating expenses. The growth of our business and the strength of our financial condition are primarily driven by our ability to achieve our annual Private Education Loan origination goals while sustaining credit quality and maintaining cost-efficient funding sources to support our originations. A brief summary of our key financial measures (net interest income; secured financings and loan sales; allowance for loan losses; charge-offs and delinquencies; operating expenses; “Core Earnings;” Private Education Loan originations; and funding sources) can be found in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2017 Form 10-K.
2018 Management Objectives
For 2018, we have set out the following major goals for ourselves: (1) prudently grow our Private Education Loan assets and revenues while continuing to diversify the mix of our funding sources; (2) maintain our strong capital position; (3) expand our product offerings to increase the level of engagement with our existing customers and attract new customers; (4) manage operating expenses while improving efficiency; (5) maintain our strong governance, risk oversight and compliance
44

infrastructure; and (6) leverage our culture to engage employees, recognize and reward contributions to business results, and develop talent to support our business strategy and growth. Here is how we plan to achieve these objectives:
Prudently Grow Private Education Loan Assets and Revenues
We will continue to pursue managed growth in our Private Education Loan portfolio in 2018 by leveraging our Sallie Mae brand, our relationship with more than 2,000 colleges and universities, and our direct consumer marketing efforts. In the first six months of 2018, we introduced six new graduate student loan products tailored to meet the needs of students in their specific fields of study. We are determined to maintain overall credit quality and cosigner rates in our Smart Option Student Loan originations. Originations were 8 percent higher in the first six months of 2018 compared with the year-ago period. The average FICO scores at approval and the cosigner rates for originations in the six months ended June 30, 2018 were 746 and 86.6 percent, compared with 747 and 87.6 percent in the six months ended June 30, 2017, respectively. In addition, to help facilitate the expected increase in our Private Education Loan originations, we plan to continue diversifying the mix of our funding sources in 2018.
A key part of our strategy to grow our Private Education Loan volume and market share will be to continue to improve our customers’ experience by maintaining cutting edge technology and providing high quality service, whether our customers choose to contact us online or over the telephone. In 2018, we are continuing to improve customer and agent-facing systems to improve the efficiency of customer service and put more self-service at our customers’ fingertips through mobile, online and call center resources.
Maintain Our Strong Capital Position
We intend to maintain levels of capital at the Bank that significantly exceed those necessary to be considered “well capitalized” by the FDIC. The Company is a source of strength for the Bank and will obtain or provide additional capital as, and if, necessary to the Bank. We regularly evaluate the quality of assets, stability of earnings, and adequacy of our allowance for loan losses, and we continue to believe our existing capital levels are sufficient to support the Bank’s plan for significant growth over the next several years while remaining “well capitalized.” As our balance sheet grows in 2018, these ratios will be stable as we now expect to generate earnings and capital sufficient to cover growth in our risk-weighted assets and remain significantly in excess of the capital levels required to be considered “well capitalized” by our regulators. As of June 30, 2018, the Bank had a Common Equity Tier 1 risk-based capital ratio of 12.0 percent, a Tier 1 risk-based capital ratio of 12.0 percent, a Total risk-based capital ratio of 13.3 percent and a Tier 1 leverage ratio of 11.2 percent, all exceeding the current regulatory guidelines for “well capitalized” institutions by a significant amount.
We do not plan to pay a common stock dividend or repurchase common shares in 2018 (except to repurchase common stock acquired as a result of taxes withheld in connection with award exercises and vesting under our employee stock-based compensation plans).
Expand Our Product Offerings to Increase Level of Engagement With Our Existing Customers and Attract New Customers
We are making investments in 2018 that will accelerate the diversification of our consumer lending platform into the Personal Loan and credit card businesses. In the first half of 2018, we began to offer six new graduate student loan products that are tailored to meet the needs of students in their specific fields of study. We expect the diversification of our consumer lending platform and these new product offerings to enhance our Private Education Loan business.
In 2017, we built the infrastructure necessary to originate and service unsecured Personal Loans to be used for non-educational purposes. In the first half of 2018, we started to originate our Personal Loan product, and recently exceeded $100 million in total originated Personal Loans. In addition, in the first six months of 2018, we acquired $594 million of Personal Loans originated by third parties.
In 2018, we have begun to lay the foundation for our credit card business. This process has included identifying and selecting a partner to help issue credit cards and service credit card accounts and to assemble the team to execute our business plan.
We believe that these two new consumer finance products are an extension of our core competencies of underwriting, marketing and servicing unsecured credits.

Manage Operating Expenses While Improving Efficiency
We will continue to measure our effectiveness in managing operating expenses by monitoring our operating efficiency ratio. We calculate and report our non-GAAP operating efficiency ratio as the ratio of (a) the total non-interest expense numerator to (b) the net revenue denominator (which consists of the sum of net interest income, before provision for credit losses, and non-interest income, excluding any gains and losses on sales of loans and securities, net and the net impact of derivative accounting as defined in our “Core Earnings” adjustments to GAAP table in “- ‘Core Earnings’ ’’ in this Form 10-Q). We believe doing so provides useful information to investors because it is a measure used by our management team to monitor our effectiveness in managing operating expenses. Other companies may use similarly titled non-GAAP financial measures that are calculated differently from the way we calculate our ratio. Accordingly, our non-GAAP operating efficiency ratio may not be comparable to similar measures used by other companies. Our long-term objective is to achieve steady declines in this ratio over the next several years.
The non-GAAP operating efficiency ratio for the three months ended June 30, 2018 was 38.3 percent compared with 39.7 percent for the year-ago period. The non-GAAP operating efficiency ratio for the six months ended June 30, 2018 was 37.4 percent compared with 38.2 percent for the six months ended June 30, 2017. The improvement in the non-GAAP operating efficiency ratio in the three and six months ended June 30, 2018 compared with the three and six month periods ended June 30, 2017, respectively, was primarily due to the growth rate in net interest income exceeding the growth rate in our expense base. The growth in our expense base in the six months ended June 30, 2018 was driven by growth in the portfolio and costs related to product diversification, platform enhancements, customer experience, FDIC assessments and higher compensation and benefits costs, including approximately $7 million related to stock compensation expense due to retirement eligible employees and to certain severance related expenses.
We expect our operating efficiency ratio to decline steadily over the next several years as the number of loans on which we earn either net interest income or servicing revenue grows to a level commensurate with our loan origination platform and we continue to manage the growth of our expense base.
Maintain Our Strong Governance, Risk Oversight and Compliance Infrastructure
We have built customer protection policies, procedures and compliance management systems sufficient to meet or exceed currently applicable regulatory standards. In addition, we have developed a strong governance framework, which includes robust oversight, education, policies and procedures supported by enterprise risk management, compliance and internal audit functions. Our goal is to consistently comply with or exceed regulatory standards for compliance and risk management.
Leverage Our Culture to Engage Employees, Recognize and Reward Contributions to Business Results, and Develop Talent to Support our Business Strategy and Growth
In the first half of 2018, we completed focus groups with a cross-functional representative sample of employees to better understand and act upon their feedback through the annual employee engagement survey. We continued to reward top performers during the year-end compensation process through differentiation of pay based on the results of the performance measurement process. Each area of the business completed its organizational planning to identify critical talent needed now and in the future, against which leadership will develop talent and employees will align their development plans.
In the second quarter of 2018, we launched a new competency model that will provide a framework and common language to define the type of talent to move the organization forward. The core and leadership competencies will provide several tools for our employees to charter their career development. We also continued to focus on talent development by piloting a leadership development program to enhance leadership competencies to more effectively achieve results. This experience included a launch of a new multi-rater assessment tool that will be leveraged to create individual development plans. We also completed our quarterly Awards of Excellence Program to recognize our highest performing employees who also demonstrate the values of our Company in the work they do.

GAAP Consolidated Earnings Summary
Three Months Ended June 30, 2018 Compared with Three Months Ended June 30, 2017
For the three months ended June 30, 2018, net income was $110 million, or $0.24 diluted earnings per common share, compared with net income of $71 million, or $0.15 diluted earnings per common share, for the three months ended June 30, 2017. The year-over-year increase in net income was due to a $71 million increase in net interest income, which was offset by a $13 million increase in provisions for credit losses, and a $24 million increase in total non-interest expenses. The reduction of the federal statutory corporate income tax rate from 35 percent to 21 percent because of the Tax Act, which was enacted on December 22, 2017, contributed approximately $21 million to net income.
The primary contributors to each of the identified drivers of changes in net income for the current quarter compared with the year-ago quarter are as follows:
•Net interest income increased by $71 million in the current quarter compared with the year-ago quarter due to a $3.7 billion increase in average loans outstanding and a 23 basis point increase in net interest margin. Net interest margin increased primarily as a result of the benefit from an increase in LIBOR rates, which increased the yield on our variable rate Private Education Loan portfolio more than it increased our cost of funds, and of growth in the higher-yielding Personal Loan portfolio. Cost of funds increased primarily due to the increase in LIBOR rates.
•Provisions for credit losses increased $13 million compared with the year-ago quarter. This increase was primarily the result of growth in the reserve for our Personal Loan portfolio. The provision for Personal Loans grew because the portfolio increased from $70 million at June 30, 2017 to $966 million at June 30, 2018. Provision expenses for our Private Education Loan portfolio declined $3 million compared with the year-ago quarter because of improved credit performance.
• Gains on sales of loans, net, resulted in a net gain of $2 million in the second quarter of 2018 as we sold the $43 million Split Loan portfolio.
•Losses on sales of securities, net, were $2 million in the second quarter of 2018 due to the sale of $41 million of mortgage-backed securities. There were no sales of securities in the year-ago period.
•Losses on derivatives and hedging activities, net, resulted in a net loss of $5 million in the second quarter of 2018 compared with a net loss of $4 million in the year-ago quarter.
•Other income increased $1 million primarily due to an increase in the tax indemnification receivable related to uncertain tax positions.
•Second-quarter 2018 operating expenses (including acquired intangible asset amortization expense) were $135 million, compared with $111 million in the year-ago quarter. The increase in operating expenses was driven by growth in the portfolio and costs related to product diversification, platform enhancements, customer experience, and higher compensation and benefits costs. Earlier this year, we indicated our intention to invest $30 million in 2018 in technology infrastructure and product diversification. We now plan to increase our investment to $40 million. The additional expense will be for marketing costs to increase our Personal Loan originations. In the second-quarter 2018, we spent $5 million toward those investments.
•Income tax expense decreased $5 million compared with the year-ago quarter. The effective tax rate decreased in the second-quarter 2018 to 26.7 percent from 38.8 percent in the year-ago quarter. The change was primarily a result of the reduction in the federal statutory corporate income tax rate from 35 percent to 21 percent under the Tax Act. During the second quarter of 2018, we recorded an additional $1 million in interest on our uncertain tax positions primarily because of an increase in the federal statutory interest rates. This amount was offset by an increase in other income due to the tax indemnification receivable related to the uncertain tax positions.
48

Six Months Ended June 30, 2018 Compared with Six Months Ended June 30, 2017
For the six months ended June 30, 2018, net income was $236 million, or $0.52 diluted earnings per common share, compared with net income of $166 million, or $0.35 diluted earnings per common share, for the six months ended June 30, 2017. The year-over-year increase in net income increase was primarily due to a $136 million increase in net interest income and an $8 million increase in total non-interest income, which was offset by a $42 million increase in provisions for credit losses and a $46 million increase in total non-interest expenses. The reduction of the federal statutory corporate income tax rate from 35 percent to 21 percent contributed approximately $44 million to net income.
The primary contributors to each of the identified drivers of changes in net income for the first six months of 2018 compared with the year-ago period are as follows:
•Net interest income increased by $136 million in the first six months compared with the year-ago period primarily due to a $3.7 billion increase in average loans outstanding. Net interest margin increased by 22 basis points primarily because of the benefit from an increase in LIBOR rates, which increased the yield on our variable rate Private Education Loan portfolio more than it increased our cost of funds, and of growth in the higher-yielding Personal Loan portfolio. Cost of funds increased primarily due to the increase in LIBOR as well as an increase in the amount of funding from higher-cost, long-term secured borrowings.
•Provisions for credit losses increased $42 million compared with the year-ago period primarily due to a $29 million increase in the provision for Personal Loans. The provision for Personal Loans grew because the portfolio increased from $70 million at June 30, 2017 to $966 million at June 30, 2018. The year-ago period also benefited from an update to our life-of-loan forecasting model for TDRs.
•Gains on sales of loans, net, resulted in a net gain of $2 million in the six months ended June 30, 2018 as we sold the $43 million Split Loan portfolio.
•Losses on sales of securities, net, were $2 million in the six months ended June 30, 2018 due to the sale of $41 million of mortgage-backed securities in the period. There were no sales of securities in the year-ago period.
•Losses on derivatives and hedging activities, net, resulted in a net loss of $1 million in the first six months of 2018 compared with a net loss of $9 million in the year-ago period. The primary factors affecting the change were interest rates and whether derivatives qualified for hedge accounting treatment.
•First-half 2018 operating expenses (including acquired intangible asset amortization expense) were $260 million, compared with $214 million in the year-ago period. The increase in operating expenses was driven by growth in the portfolio and costs related to product diversification, platform enhancements, customer experience, FDIC assessments and higher compensation and benefits costs. Earlier this year, we indicated our intention to invest $30 million in 2018 in technology infrastructure and product diversification. We now plan to increase our investment to $40 million. The additional expense will be for marketing costs to increase our Personal Loan originations. Year-to-date, those investments have totaled approximately $6 million.
•Income tax expense decreased $15 million compared with the year-ago period. The effective tax rate decreased in the first six months of 2018 to 25.6 percent from 36.6 percent in the year-ago period. The change was primarily a result of the reduction in the federal statutory corporate income tax rate from 35 percent to 21 percent under the Tax Act. The effective tax rate for the six months ended June 30, 2017 included a $6 million benefit recorded in the first quarter of 2017 related to a new stock compensation accounting standard, which changed the treatment of excess tax benefits/deficiencies related to the settlement of employee stock-based awards.

“Core Earnings”
We prepare financial statements in accordance with GAAP. However, we also produce and report our after-tax earnings on a separate basis that we refer to as “Core Earnings.” The difference between our “Core Earnings” and GAAP results for periods presented generally is driven by the unrealized, mark-to-market gains (losses) on derivatives contracts recognized in GAAP, but not in “Core Earnings.”
“Core Earnings” recognizes the difference in accounting treatment based upon whether a derivative qualifies for hedge accounting treatment and eliminates the earnings impact associated with hedge ineffectiveness and derivatives we use as an economic hedge but which do not qualify for hedge accounting treatment. We enter into derivative instruments to economically hedge interest rate and cash flow risk associated with our portfolio. We believe that our derivatives are effective economic hedges, and as such, are a critical element of our interest rate risk management strategy. Those derivative instruments that qualify for hedge accounting treatment have their related cash flows recorded in interest income or interest expense along with the hedged item. Hedge ineffectiveness related to these derivatives is recorded in “Gains (losses) on derivatives and hedging activities, net.” Some of our derivatives do not qualify for hedge accounting treatment and the stand-alone derivative must be marked-to-fair value in the income statement with no consideration for the corresponding change in fair value of the hedged item. These gains and losses, recorded in “Gains (losses) on derivatives and hedging activities, net,” are primarily caused by interest rate volatility and changing credit spreads during the period as well as the volume and term of derivatives not receiving hedge accounting treatment. Cash flows on derivative instruments that do not qualify for hedge accounting are not recorded in interest income and interest expense; they are recorded in non-interest income: “Gains (losses) on derivatives and hedging activities, net.”
The adjustments required to reconcile from our “Core Earnings” results to our GAAP results of operations, net of tax, relate to differing treatments for our derivative instruments used to hedge our economic risks that do not qualify for hedge accounting treatment or that do qualify for hedge accounting treatment but result in ineffectiveness, net of tax. The amount recorded in “Gains (losses) on derivatives and hedging activities, net” includes (a) the accrual of the current payment on the interest rate swaps that do not qualify for hedge accounting treatment, (b) the change in fair values related to future expected cash flows for derivatives that do not qualify for hedge accounting treatment and (c) ineffectiveness on derivatives that receive hedge accounting treatment. For purposes of “Core Earnings”, we are including in GAAP earnings the current period accrual amounts (interest reclassification) on the swaps and excluding the remaining ineffectiveness (and change in fair values for those derivatives not qualifying for hedge accounting treatment). “Core Earnings” is meant to represent what earnings would have been had these derivatives qualified for hedge accounting and there was no ineffectiveness.
“Core Earnings” are not a substitute for reported results under GAAP. We provide a “Core Earnings” basis of presentation because (i) earnings per share computed on a “Core Earnings” basis is one of several measures we utilize in establishing management incentive compensation and (ii) we believe it better reflects the financial results for derivatives that are economic hedges of interest rate risk but which do not qualify for hedge accounting treatment.
GAAP provides a uniform, comprehensive basis of accounting. Our “Core Earnings” basis of presentation differs from GAAP in the way it treats derivatives as described above.
The following table shows the amount in “Losses on derivatives and hedging activities, net” that relates to the interest reclassification on the derivative contracts.

(1) Derivative Accounting: “Core Earnings” exclude periodic unrealized gains and losses 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 (but include current period accruals on the derivative instruments), net of tax. Under GAAP, for our derivatives held to maturity, the cumulative net unrealized gain or loss over the life of the contract will equal $0.
(2) “Core Earnings” tax rate is based on the effective tax rate at the Bank where the derivative instruments are held.

“Loan consolidations to third-parties” and “Repayments and other” are both significantly affected by the volume of loans in our portfolio in full principal and interest repayment status. Loans in full principal and interest repayment status in our Private Education Loan portfolio at June 30, 2018 increased by 34 percent compared with June 30, 2017, and now total 39 percent of our Private Education Loan portfolio at June 30, 2018.
“Loan consolidations to third-parties” for the three months ended June 30, 2018 total 3.0 percent of our Private Education Loan portfolio in full principal and interest repayment status at June 30, 2018, or 1.2 percent of our total Private Education Loan portfolio at June 30, 2018, compared with the year-ago period of 2.6 percent of our Private Education Loan portfolio in full principal and interest repayment status, or 0.9 percent of our total Private Education Loan portfolio, respectively. Historical experience has shown that loan consolidation activity is heightened in the period when the loan initially enters full principal and interest repayment status and then subsides over time.
The “Repayments and other” category includes all scheduled repayments, as well as voluntary prepayments, made on loans in repayment (including loans in full principal and interest repayment status) and also includes charge-offs. Consequently,
56

this category can be significantly affected by the volume of loans in repayment. The increase in the volume of loans in repayment accounts for the vast majority of the aggregate increase in loan consolidations, scheduled repayments, unscheduled prepayments and capitalized interest set forth above.

Private Education Loan Allowance for Loan Losses
In establishing the allowance for Private Education Loan losses as of June 30, 2018, we considered several factors with respect to our Private Education Loan portfolio, in particular, credit quality and delinquency, forbearance and charge-off trends.
Private Education Loans in full principal and interest repayment status were 39 percent of our total Private Education Loan portfolio at June 30, 2018 compared with 35 percent at June 30, 2017.
For a more detailed discussion of our policy for determining the collectability of Private Education Loans and maintaining our allowance for Private Education Loan losses, see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies and Estimates — Allowance for Loan Losses” in the 2017 Form 10-K.

_______

(1) | Represents fair value adjustments on loans sold.

(2) | Loans in repayment include loans on which borrowers are making interest only or fixed payments, as well as loans that have entered full principal and interest repayment status after any applicable grace period.

As part of concluding on the adequacy of the allowance for loan losses, we review key allowance and loan metrics. The most significant of these metrics considered are the allowance coverage of net charge-offs ratio; the allowance as a percentage of ending total loans and of ending loans in repayment; and delinquency and forbearance percentages. The allowance as a percentage of ending total loans and of ending loans in repayment increased at June 30, 2018 compared with June 30, 2017 because of an increase in our TDRs (for which we hold a life-of-loan allowance) and an increase in the percentage of loans in full principal and interest repayment status.

Use of Forbearance as a Private Education Loan Collection Tool
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 a loan is 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. We grant forbearance in our servicing centers if a borrower who is current requests it for increments of three months at a time, for up to 12 months. 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. 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 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 their 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. If specific requirements are met, the forbearance can cure 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.
The tables below show the composition and status of the Private Education Loan portfolio aged by number of months in active repayment status (months for which a scheduled monthly payment was due). Active repayment status includes loans on which borrowers are making interest only or fixed payments, as well as loans that have entered full principal and interest repayment status after any applicable grace period. Our experience shows that the percentage of loans in forbearance status decreases the longer the loans have been in active repayment status. At June 30, 2018, loans in forbearance status as a percentage of total loans in repayment and forbearance were 2.5 percent for Private Education Loans that have been in active repayment status for fewer than 25 months. Approximately 73 percent of our Private Education Loans in forbearance status have been in active repayment status fewer than 25 months.

Liquidity and Capital Resources
Funding and Liquidity Risk Management
Our primary liquidity needs include our ongoing ability to fund our businesses throughout market cycles, including during periods of financial stress, our ongoing ability to fund originations of Private Education Loans and servicing our Bank deposits. To achieve these objectives, we analyze and monitor our liquidity needs, maintain excess liquidity and access diverse funding sources, such as deposits at the Bank, issuance of secured debt primarily through asset-backed securitizations and other financing facilities. It is our policy to manage operations so liquidity needs are fully satisfied through normal operations to avoid unplanned asset sales under emergency conditions. Our liquidity management is governed by policies approved by our Board of Directors. Oversight of these policies is performed in the Asset and Liability Committee, a management-level committee.
These policies take into account the volatility of cash flow forecasts, expected maturities, anticipated loan demand and a variety of other factors to establish minimum liquidity guidelines.
Key risks associated with our liquidity relate to our ability to access the capital markets and the markets for bank deposits at reasonable rates. This ability may be affected by our performance, competitive pressures, the macroeconomic environment and the impact they have on the availability of funding sources in the marketplace.

Deposits
The following table summarizes total deposits.

|  | June 30, |  | December 31,
(Dollars in thousands) |  | 2018 |  | 2017
Deposits - interest bearing |  | $ | 16,743,885 |  |  | $ | 15,504,330 |
Deposits - non-interest bearing |  | 2,072 |  |  | 1,053 |
Total deposits |  | $ | 16,745,957 |  |  | $ | 15,505,383 |

Our total deposits of $16.7 billion were comprised of $8.7 billion in brokered deposits and $8.0 billion in retail and other deposits at June 30, 2018, compared to total deposits of $15.5 billion, which were comprised of $8.2 billion in brokered deposits and $7.3 billion in retail and other deposits, at December 31, 2017.
Interest bearing deposits as of June 30, 2018 and December 31, 2017 consisted of retail and brokered non-maturity savings deposits, retail and brokered non-maturity MMDAs and retail and brokered CDs. Interest bearing deposits include deposits from Educational 529 and Health Savings plans that diversify our funding sources and additional deposits we consider to be core. These and other large omnibus accounts, aggregating the deposits of many individual depositors, represented $5.7 billion of our deposit total as of June 30, 2018, compared with $5.5 billion at December 31, 2017.
Some of our deposit products are serviced by third-party providers. Placement fees associated with the brokered CDs are amortized into interest expense using the effective interest rate method. We recognized placement fee expense of $3 million and $2 million in the three months ended June 30, 2018 and 2017, respectively, and placement fee expense of $6 million and $4 million in the six months ended June 30, 2018 and 2017, respectively. Fees paid to third-party brokers related to brokered CDs were $12 million and $3 million for the three months ended June 30, 2018 and 2017, respectively, and fees paid to third-party brokers related to brokered CDs were $19 million and $5 million for the six months ended June 30, 2018 and 2017, respectively.
Interest bearing deposits at June 30, 2018 and December 31, 2017 are summarized as follows:

Counterparty Exposure
Counterparty exposure related to financial instruments arises from the risk that a lending, investment or derivative counterparty will not be able to meet its obligations to us.
Excess cash is generally invested with the FRB on an overnight basis or in the FRB’s Term Deposit Facility, minimizing counterparty exposure on cash balances.
Our investment portfolio is primarily comprised of a small portfolio of mortgage-backed securities issued by government agencies and government-sponsored enterprises that are purchased to meet Community Reinvestment Act targets. Additionally, our investing activity is governed by Board-approved limits on the amount that is allowed to be invested with any one issuer based on the credit rating of the issuer, further minimizing our counterparty exposure. Counterparty credit risk is considered when valuing investments and considering impairment.
Related to derivative transactions, protection against counterparty risk is generally provided by International Swaps and Derivatives Association, Inc. Credit Support Annexes (“CSAs”), or clearinghouses for over-the-counter derivatives. CSAs require a counterparty to post collateral if a potential default would expose the other party to a loss. All derivative contracts entered into by the Bank are covered under CSAs or clearinghouse agreements and require collateral to be exchanged based on the net fair value of derivatives with each counterparty. Our exposure is limited to the value of the derivative contracts in a gain position, less any collateral held by us and plus collateral posted with the counterparty.
Title VII of 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 CME and the LCH. The CME and the LCH made amendments to their respective rules that resulted in the prospective accounting treatment of certain daily variation margin payments being considered as the legal settlement of the outstanding exposure of the derivative instead of the posting of collateral. The CME rule changes, which became effective in January 2017, and the LCH rule changes, which became effective in January 2018, result in all variation margin payments on derivatives cleared through the CME and LCH being accounted for as legal settlement. As of June 30, 2018, $5.9 billion notional of our derivative contracts were cleared on the CME and $0.6 billion were cleared on the LCH. The derivative contracts cleared through the CME and LCH represent 90.3 percent and 9.7 percent, respectively, of our total notional derivative contracts of $6.5 billion at June 30, 2018.
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. Interest income (expense) related to variation margin on derivatives that are not designated as hedging instruments or are designated as fair value relationships is recognized as a gain (loss) rather than as interest income (expense). Changes in fair value for derivatives not designated as hedging instruments will be presented as realized gains (losses).
Our exposure is limited to the value of the derivative contracts in a gain position less any collateral held and plus any collateral posted. When there is a net negative exposure, we consider our exposure to the counterparty to be zero. At June 30, 2018 and December 31, 2017, we had a net positive exposure (derivative gain positions to us, less collateral held by us and plus collateral posted with counterparties) related to derivatives of $30 million and $20 million, respectively.
We have liquidity exposure related to collateral movements between us and our derivative counterparties. Movements in the value of the derivatives, which are primarily affected by changes in interest rates, may require us to return cash collateral held or may require us to access primary liquidity to post collateral to counterparties.
As of June 30, 2018, LCH was not rated by any of the major rating agencies. However, all derivative counterparties are evaluated internally for credit worthiness. LCH has been deemed by management to have strong liquidity and robust capital levels as of our most recent credit review and has been assigned our strongest risk rating.

Regulatory Capital
The Bank is subject to various regulatory capital requirements administered by federal and state banking authorities. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material adverse effect on our business, results of operations and financial condition. Under U.S. Basel III and the regulatory framework for prompt corrective action, the Bank must meet specific capital standards that involve quantitative measures of its assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and its classification under the prompt corrective action framework are also subject to qualitative judgments by the regulators about components of capital, risk weightings and other factors.
“Well capitalized” regulatory requirements are the quantitative measures established by regulation to ensure capital adequacy. To qualify as “well capitalized,” the Bank must maintain minimum amounts and ratios (set forth in the table below) of Common Equity Tier 1, Tier 1 and Total capital to risk-weighted assets and of Tier 1 capital to average assets. The following capital amounts and ratios are based upon the Bank’s assets.

|  | Actual |  | “Well Capitalized” Regulatory Requirements
(Dollars in thousands) |  | Amount | Ratio |  | Amount |  | Ratio
As of June 30, 2018 |  |  |  |  |  |  |
Common Equity Tier 1 Capital (to Risk-Weighted Assets) |  | $ | 2,617,021 |  | 12.0 | % |  | $ | 1,417,350 |  | > | 6.5 | %

Capital Management
The Bank seeks to remain “well capitalized” at all times with sufficient capital to support asset growth and operating needs, address unexpected credit risks and to protect the interests of depositors and the Deposit Insurance Fund administered by the FDIC. The Bank is required by its regulators, the UDFI and the FDIC, to comply with mandated capital ratios. We intend to maintain levels of capital at the Bank that significantly exceed the levels of capital necessary to be considered “well capitalized” by the FDIC. The Company is a source of strength for the Bank and will provide additional capital if necessary. The Board of Directors and management periodically evaluate the quality of assets, the stability of earnings, and the adequacy of the allowance for loan losses for the Bank. We believe that current and projected capital levels are appropriate for 2018. As our balance sheet continues to grow in 2018, these ratios will be stable as we now expect to generate earnings and capital sufficient to cover growth in our risk-weighted assets and remain significantly in excess of the capital levels required to be considered “well capitalized” by our regulators. We do not plan to pay dividends on our common stock. We do not intend to initiate share repurchase programs as a means to return capital to shareholders. We only expect to repurchase common stock acquired in connection with taxes withheld in connection with award exercises and vesting under our employee stock-based compensation plans. Our Board of Directors will periodically reconsider these matters.
The Bank must comply with U.S. Basel III, which is aimed at increasing both the quantity and quality of regulatory capital. Certain aspects of U.S. Basel III, including new deductions from and adjustments to regulatory capital and a capital conservation buffer, are being phased in over several years. The Bank’s Capital Policy requires management to monitor these capital standards and the Bank’s compliance with them. The Bank is subject to the following minimum regulatory capital ratios under U.S. Basel III: a Common Equity Tier 1 risk-based capital ratio of 4.5 percent, a Tier 1 risk-based capital ratio of 6.0 percent, a Total risk-based capital ratio of 8.0 percent, and a Tier 1 leverage ratio of 4.0 percent. In addition, the Bank is subject to a phased-in Common Equity Tier 1 capital conservation buffer: 1.25 percent of risk-weighted assets for 2017; 1.875 percent for 2018; and the fully phased-in level of greater than 2.5 percent effective as of January 1, 2019. Failure to maintain the buffer will result in restrictions on the Bank’s ability to make capital distributions, including the payment of dividends, and to pay discretionary bonuses to executive officers. Including the buffer, by January 1, 2019, the Bank will be required to maintain the following minimum capital ratios: a Common Equity Tier 1 risk-based capital ratio of greater than 7.0 percent, a Tier 1 risk-based capital ratio of greater than 8.5 percent and a Total risk-based capital ratio of greater than 10.5 percent.
To qualify as “well capitalized” under the prompt corrective action framework for insured depository institutions, the Bank must maintain a Common Equity Tier 1 risk-based capital ratio of at least 6.5 percent, a Tier 1 risk-based capital ratio of at least 8.0 percent, a Total risk-based capital ratio of at least 10.0 percent, and a Tier 1 leverage ratio of at least 5.0 percent.
As of June 30, 2018, the Bank had a Common Equity Tier 1 risk-based capital ratio of 12.0 percent, a Tier 1 risk-based capital ratio of 12.0 percent, a Total risk-based capital ratio of 13.3 percent and a Tier 1 leverage ratio of 11.2 percent, which are each in excess of the current “well capitalized” standard for insured depository institutions. If calculated today based on the fully phased-in U.S. Basel III standards, our ratios would also exceed the capital levels required under U.S. Basel III and the “well capitalized” standard.
Dividends
The Bank is chartered under the laws of the State of Utah and its deposits are insured by the FDIC. The Bank’s ability to pay dividends is subject to the laws of Utah and the regulations of the FDIC. Generally, under Utah’s industrial bank laws and regulations as well as FDIC regulations, the Bank may pay dividends to the Company from its net profits without regulatory approval if, following the payment of the dividend, the Bank’s capital and surplus would not be impaired. The Bank paid no dividends for the six months ended June 30, 2018 and June 30, 2017. For the foreseeable future, we expect the Bank to only pay dividends to the Company as may be necessary to provide for regularly scheduled dividends payable on the Company’s Series B Preferred Stock.

Borrowings
Outstanding borrowings consist of unsecured debt and secured borrowings issued through our term ABS program and our ABCP Facility. The issuing entities for those secured borrowings are VIEs and are consolidated for accounting purposes. The following table summarizes our borrowings at June 30, 2018 and December 31, 2017, respectively. For additional information, see Notes to Consolidated Financial Statements, Note 6, “Borrowings.”

Other Borrowing Sources
We maintain discretionary uncommitted Federal Funds lines of credit with various correspondent banks, which totaled $125 million at June 30, 2018. The interest rate charged to us on these lines of credit is priced at Fed Funds plus a spread at the time of borrowing and is payable daily. We did not utilize these lines of credit in the six months ended June 30, 2018 or in the year ended December 31, 2017.
We established an account at the FRB to meet eligibility requirements for access to the Primary Credit borrowing facility at the FRB’s Window. The Primary Credit borrowing facility is a lending program available to depository institutions that are in generally sound financial condition. All borrowings at the Window must be fully collateralized. We can pledge to the FRB asset-backed and mortgage-backed securities, as well as FFELP Loans and Private Education Loans, as collateral for borrowings at the Window. Generally, collateral value is assigned based on the estimated fair value of the pledged assets. At June 30, 2018 and December 31, 2017, the value of our pledged collateral at the FRB totaled $2.5 billion and $2.6 billion, respectively. The interest rate charged to us is the discount rate set by the FRB. We did not utilize this facility in the six months ended June 30, 2018 or in the year ended December 31, 2017.
Contractual Loan Commitments
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 at the start of the second semester or subsequent trimesters). At June 30, 2018, we had $1.7 billion of outstanding contractual loan commitments which we expect to fund during the remainder of the 2018/2019 academic year. At June 30, 2018, we had a $0.6 million reserve recorded in “Other Liabilities” to cover expected losses that may occur during the one-year loss emergence period on these unfunded commitments.

Critical Accounting Policies and Estimates
Management’s Discussion and Analysis of Financial Condition and Results of Operations addresses our consolidated financial statements, which have been prepared in accordance with GAAP. A discussion of our critical accounting policies, which include allowance for loan losses, fair value measurement, transfers of financial assets and the VIE consolidation model, and derivative accounting, can be found in our 2017 Form 10-K. There were no significant changes to these critical accounting policies during the second quarter of 2018. However, related to derivative accounting, in the first quarter of 2018 we changed the accounting treatment of variation margin payments on derivatives cleared through the LCH as a result of the LCH adopting rule changes, as described below.
Derivative Accounting
The CME and the LCH made amendments to their respective rules that resulted in the prospective accounting treatment of certain daily variation margin payments being considered as the legal settlement of the outstanding exposure of the derivative instead of the posting of collateral. The CME rule changes, which became effective in January 2017, and the LCH rule changes, which became effective in January 2018, result in all variation margin payments on derivatives cleared through the CME and LCH being accounted for as legal settlement. As of June 30, 2018, $5.9 billion notional of our derivative contracts were cleared on the CME and $0.6 billion were cleared on the LCH. The derivative contracts cleared through the CME and LCH represent 90.3 percent and 9.7 percent, respectively, of our total notional derivative contracts of $6.5 billion at June 30, 2018.
For derivatives cleared through the CME and the 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. Interest income (expense) related to variation margin on derivatives that are not designated as hedging instruments or are designated as fair value relationships is recognized as a gain (loss) rather than as interest income (expense). Changes in fair value for derivatives not designated as hedging instruments will be presented as realized gains (losses).

Item 3. | Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Sensitivity Analysis
Our interest rate risk management program seeks to manage and control interest rate risk, thereby reducing our exposure to fluctuations in interest rates and achieving consistent and acceptable levels of profit in any rate environment and sustainable growth in net interest income over the long term. We evaluate and monitor interest rate risk through two primary methods:

• | Earnings at Risk (“EAR”), which measures the impact of hypothetical changes in interest rates on net interest income; and

• | Economic Value of Equity (“EVE”), which measures the sensitivity or change in the economic value of equity to changes in interest rates.

A number of potential interest rate scenarios are simulated using our asset liability management system. The Bank is the primary source of interest rate risk within the Company. At present, the majority of the Bank’s earning assets are priced off of 1-month LIBOR. Therefore, 1-month LIBOR is considered a core rate in our interest rate risk analysis. Other interest rate changes are correlated to changes in 1-month LIBOR for analytic purposes, with higher or lower correlations based on historical relationships. In addition, key rates are modeled with a floor, which indicates how low each specific rate is likely to move in practice. Rates are adjusted up or down via a set of scenarios that includes both rate shocks and ramps. Rate shocks represent an immediate and sustained change in 1-month LIBOR, with the resulting changes in other indices correlated accordingly. Interest rate ramps represent a linear increase in 1-month LIBOR over the course of 12 months, with the resulting changes in other indices correlated accordingly.
The following tables summarize the potential effect on earnings over the next 24 months and the potential effect on market values of balance sheet assets and liabilities at June 30, 2018 and 2017, based upon a sensitivity analysis performed by management assuming a hypothetical increase or decrease in market interest rates of 100 basis points and a hypothetical increase in market interest rates of 300 basis points while funding spreads remain constant. At today’s level of interest rates, a 300 basis point downward rate shock does not provide a meaningful indication of interest rate sensitivity and has therefore not been included in the results reported below. The EVE sensitivity is applied only to financial assets and liabilities, including hedging instruments, that existed at the balance sheet date, and does not take into account new assets, liabilities, commitments or hedging instruments that may arise in the future.
The results indicate a market risk profile that has increased in sensitivity from the prior year’s results. A portion of the change is due to two modeling assumption changes that are detailed in the discussion that follows. The majority of the increased sensitivity in the risk profile, however, is structural and is planned to reverse itself as fixed rate loan originations over the next 12 months will gradually offset a block of fixed rate funding that has been placed on the balance sheet in the first half of 2018, in anticipation of fixed rate Private Education Loan disbursements. A discussion of the impact of the two changes in modeling assumptions follows.

| June 30,
| 2018 |  | 2017
| +300 Basis Points |  | +100 Basis Points |  | -100 Basis Points |  | +300 Basis Points |  | +100 Basis Points |  | -100 Basis Points
EAR - Shock | +10.3% |  | +3.6% |  | -2.8% |  | +8.2% |  | +2.7% |  | -2.6%
EAR - Ramp | +9.4% |  | +3.5% |  | -2.1% |  | +5.1% |  | +2.4% |  | -1.7%
EVE | +11.6% |  | +3.9% |  | -4.1% |  | +1.8% |  | +0.5% |  | -0.5%

The EVE results in the table above for June 30, 2018 reflect two changes in the modeling assumptions. First, we have lengthened the assumed average lives of our indeterminate maturity retail deposit balances, which are now expected to persist longer than previously assumed. As an indication of the significance of this change, the December 31, 2017 results showed sensitivity of +6.4 percent for the “+300 basis points shock,” +2.0 percent for the “+100 basis points shock,” and -1.9 percent for the “-100 basis points shock.” Without the modeling changes lengthening the average life of deposits, the December 31,
71

2017 results would have been +5.4 percent for the “+300 basis points shock,” +1.6 percent for the “+100 basis points shock” and -1.4 percent for the “-100 basis points shock.” A similar impact is noticeable when comparing June 30, 2018 results to June 30, 2017 results; EVE sensitivity has increased. A second modeling change recognizes the more competitive market for indeterminate maturity retail deposits. Beginning with the March 31, 2018 results, we assume that the interest rates offered on these deposits would not reprice below a given level, despite a downward interest rate shock scenario. The model holds retail deposit rates at levels similar to the rates available in the market throughout the low interest rate environment of the past several years. As we look at the impact this change had in the quarter it was implemented, had this change not been incorporated into the March 31, 2018 EVE results, which reported a -3.0 percent change in the “-100 basis points shock,” the EVE sensitivity for March 31, 2018 would have been -1.8 percent in the “-100 basis points shock.” The upward rate scenario results were not impacted by this change.
A primary objective in our funding is to manage our sensitivity to changing interest rates by generally funding our assets with liabilities of similar interest rate repricing characteristics. This funding objective is frequently obtained through the use of derivatives. Uncertainty in loan repayment cash flows and the pricing behavior of our non-maturity retail deposits pose challenges in achieving our interest rate risk objectives. In addition to these considerations, we can have a mismatch in the index (including the frequency of reset) of floating rate debt versus floating rate assets.
As part of its suite of financial products, the Bank offers fixed-rate Private Education Loans. As with other Private Education Loans, the term to maturity is lengthy, and the customer has the option to repay the loan faster than the promissory note requires. Asset securitization and fixed-rate CDs provide intermediate to long-term fixed-rate funding for some of these assets. Additionally, a portion of the fixed-rate loans have been hedged with derivatives, which have been used to convert a portion of variable-rate funding to fixed-rate to match the anticipated cash flows of these loans. Any unhedged position arising from the fixed-rate loan portfolio is monitored and modeled to ensure that the interest rate risk does not cause the Company to exceed its policy limits for earnings at risk or for the value of equity at risk.
In the preceding tables, the interest rate sensitivity analysis reflects the heavy balance sheet mix of fully variable LIBOR-based loans, which exceeds the mix of fully variable funding, which includes brokered CDs that have been converted to LIBOR through derivative transactions. The analysis does not anticipate that retail MMDAs or retail savings balances, while relatively sensitive to interest rate changes, will reprice to the full extent of interest rate shocks or ramps. Also considered is (i) the impact of FFELP loans, which receive floor income in low interest rate environments, and will therefore not reprice fully with interest rate shocks and (ii) the impact of fixed-rate loans that have not been fully match-funded through derivative transactions and fixed-rate funding from CDs and asset securitization. An additional consideration is the implementation of a loan cap of 25 percent on variable-rate loans originated on and after September 25, 2016. As of June 30, 2018, there were $6.1 billion of loans with 25 percent interest rate caps on the balance sheet. While the Bank typically exhibits a sensitivity profile that will result in a slight increase in net interest income as rates rise, and decrease somewhat when interest rates fall, this sensitivity position will fluctuate somewhat during the year, depending on the funding mix in place at the time of the analysis.
Although we believe that these measurements provide an estimate of our interest rate sensitivity, they do not account for potential changes in credit quality, balance sheet mix and size of our balance sheet. They also do not account for other business developments that could affect net income, or for management actions that could affect net income or could be taken to change our risk profile. Accordingly, we can give no assurance that actual results would not differ materially from the estimated outcomes of our simulations. Further, such simulations do not represent our current view of expected future interest rate movements.

Asset and Liability Funding Gap
The table below presents our assets and liabilities (funding) arranged by underlying indices as of June 30, 2018. In the following GAAP presentation, the funding gap only includes derivatives that qualify as effective hedges (those derivatives which are reflected in net interest income, as opposed to those reflected in the “gains (losses) on derivatives and hedging activities, net” line on the consolidated statements of income). The difference between the asset and the funding is the funding gap for the specified index. This represents at a high level our exposure to interest rate risk in the form of basis risk and repricing risk, which is the risk that the different indices may reset at different frequencies or may not move in the same direction or at the same magnitude. (Note that all fixed-rate assets and liabilities are aggregated into one line item, which does not capture the differences in time due to maturity.)

(Dollars in millions) Index |  | Frequency of Variable Resets |  | Assets |  | Funding (1) |  | Funding Gap
3-month Treasury bill |  | weekly |  | $ | 128.5 |  |  | $ | — |  |  | $ | 128.5 |
Prime |  | monthly |  | 2.6 |  |  | — |  |  | 2.6 |
3-month LIBOR |  | quarterly |  | — |  |  | 399.2 |  |  | (399.2 | )
1-month LIBOR |  | monthly |  | 13,599.1 |  |  | 8,880.8 |  |  | 4,718.3 |
1-month LIBOR |  | daily |  | 756.9 |  |  | — |  |  | 756.9 |
Non-Discrete reset(2) |  | daily/weekly |  | 2,158.4 |  |  | 3,146.5 |  |  | (988.1 | )
Fixed Rate(3) |  |  |  | 7,543.7 |  |  | 11,762.7 |  |  | (4,219.0 | )
Total |  |  |  | $ | 24,189.2 |  |  | $ | 24,189.2 |  |  | $ | — |

______________________

(1) | Funding (by index) includes the impact of all derivatives that qualify as effective hedges.

(2) | Assets include restricted and unrestricted cash equivalents and other overnight type instruments. Funding includes liquid retail deposits and the obligation to return cash collateral held related to derivatives exposures.

(3) | Assets include receivables and other assets (including premiums and reserves). Funding includes unswapped time deposits, liquid MMDAs swapped to fixed rates and stockholders' equity.

The “Funding Gap” in the above table shows primarily mismatches in the 1-month LIBOR, fixed-rate, Non-Discrete reset and 3-month LIBOR categories. As changes in 1-month and 3-month LIBOR are generally quite highly correlated, the funding gap associated with 3-month LIBOR is expected to partially offset the 1-month LIBOR gaps. We consider the overall risk to be moderate since the funding in the Non-Discrete bucket is our liquid retail portfolio, which we have significant flexibility to reprice at any time, and the funding in the fixed-rate bucket includes $2.3 billion of equity and $0.5 billion of non-interest bearing liabilities. In addition, as of June 30, 2018, a block of fixed rate funding has been placed on the balance sheet in anticipation of upcoming fixed rate loan disbursements.
We use interest rate swaps and other derivatives to achieve our risk management objectives. Our asset liability management strategy is to match assets with debt (in combination with derivatives) that have the same underlying index and reset frequency or have interest rate characteristics that we believe are highly correlated. The use of funding with index types and reset frequencies that are different from our assets exposes us to interest rate risk in the form of basis and repricing risk. This could result in our cost of funds not moving in the same direction or with the same magnitude as the yield on our assets. While we believe this risk is low, as all of these indices are short-term with rate movements that are highly correlated over a long period of time, market disruptions (which have occurred in recent years) can lead to a temporary divergence between indices, resulting in a negative impact to our earnings.

Item 4. | Controls and Procedures

Disclosure Controls and Procedures
Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of June 30, 2018. Based on this evaluation, our principal executive officer and principal financial officer concluded that, as of June 30, 2018, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is (a) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (b) accumulated and communicated to our management, including our principal executive officer and principal financial officer as appropriate, to allow timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting
No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the fiscal quarter ended June 30, 2018 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. | Legal Proceedings

We and our subsidiaries and affiliates are subject to various claims, lawsuits and other actions that arise in the normal course of business. It is common for the Company, our subsidiaries and affiliates to receive information and document requests and investigative demands from state attorneys general, legislative committees and administrative agencies. These requests may be for informational or regulatory purposes and may relate to our business practices, the industries in which we operate, or other companies with whom we conduct business. Our practice has been and continues to be to cooperate with these bodies and be responsive to any such requests.
Pursuant to the terms of the Spin-Off and applicable law, Navient assumed responsibility for all liabilities (whether accrued, contingent or otherwise and whether known or unknown) arising out of or resulting from the conduct of pre-Spin-Off SLM and its subsidiaries’ businesses prior to the Spin-Off, other than certain specifically identified liabilities relating to the conduct of our consumer banking business. Nonetheless, given the prior usage of the Sallie Mae and SLM names by entities now owned by Navient, we and our subsidiaries may from time to time be improperly named as defendants in legal proceedings where the allegations at issue are the legal responsibility of Navient. Most of these legal proceedings involve matters that arose in whole or in part in the ordinary course of business of pre-Spin-Off SLM. Likewise, as the period of time since the Spin-Off increases, so does the likelihood any allegations that may be made may be in part for our own actions in a post-Spin-Off time period and in part for Navient’s conduct in a pre-Spin-Off time period. We will not be providing information on these proceedings unless there are material issues of fact or disagreement with Navient as to the bases of the proceedings or responsibility therefor that we believe could have a material, adverse impact on our business, assets, financial condition, liquidity or outlook if not resolved in our favor.
On January 18, 2017, the Illinois Attorney General filed a separate lawsuit in Illinois state court against Navient - its subsidiaries Navient Solutions, Inc., Pioneer Credit Recovery, Inc., and General Revenue Corporation - and the Bank arising out of the Multi-State Investigation. On March 20, 2017, the Bank moved to dismiss the Illinois Attorney General action as to the Bank, arguing, among other things, the complaint failed to allege with sufficient particularity or specificity how the Bank was responsible for any of the alleged conduct, most of which predated the Bank’s existence. The Illinois Court heard oral arguments on July 18, 2017. On July 10, 2018, the Court granted the Bank’s motion to dismiss without prejudice. The Court granted the Illinois Attorney General 28 days to amend the complaint. As contemplated by the Separation and Distribution Agreement relating to, and the structure of, the Spin-Off, Navient is legally responsible for, has assumed, and has accepted responsibility to indemnify the Company against, all costs, expenses, losses and remediation that may arise from these matters.
On July 17, 2018, the Mississippi Attorney General filed a lawsuit in Mississippi state court against Navient, Navient Solutions, LLC, and the Bank arising out of the Multi-State Investigation. The complaint alleges unfair and deceptive trade practices against all three defendants as to private loan origination practices from 2000 to 2009. The complaint further alleges that Navient assumed responsibility for these matters under the Separation and Distribution Agreement for the alleged conduct. The Bank intends to seek indemnification from Navient as to all costs, expenses, losses and remediation that may arise from this lawsuit. The Bank was served with the complaint on July 19, 2018 and currently has 30 days to respond.
To date, three other state attorneys general (California, Washington and Pennsylvania) have filed suits against Navient and one or more of its current subsidiaries arising out of matters arising from the Multi-State Investigation. Neither SLM, the Bank, nor any of their current subsidiaries are named in, or otherwise a party to, the California, Washington or Pennsylvania lawsuits, and no claims are asserted against them. Each complaint asserts in its own fashion that Navient assumed responsibility for these matters under the Separation and Distribution Agreement for the alleged conduct in the complaints.
Regulatory Update
On May 13, 2014, the Bank reached a settlement with the Department of Justice (the “DOJ”) regarding compliance with the SCRA. In connection with the settlement, the Bank became subject to the DOJ Consent Order, which was approved by the U.S. District Court for the District of Delaware on September 29, 2014. Under the terms of the Separation and Distribution Agreement, Navient is responsible for funding all liabilities under the regulatory order and, as of the date hereof, has funded all liabilities other than fines directly levied against the Bank in connection with these matters which the Bank is required to pay.
76

The Bank continues to be in full compliance with the DOJ Consent Order, including policy and procedure updates. Pursuant to the terms of the DOJ Consent Order, the Bank will remain subject to certain DOJ reporting and record-keeping requirements until September 29, 2018.
In May 2014, the Bank received a Civil Investigative Demand (“CID”) from the Consumer Financial Protection Bureau (the “CFPB”) as part of the CFPB Investigation. Two state attorneys general also provided the Bank identical CIDs and other state attorneys general have become involved in the Multi-State Investigation. To the extent requested, the Bank has been cooperating fully with the CFPB and the attorneys general conducting the Multi-State Investigation. Given the timeframe covered by the CIDs, the CFPB Investigation and the Multi-State Investigation, and the focus on practices and procedures previously conducted by Navient and its servicing subsidiaries prior to the Spin-Off, Navient is leading the response to these investigations. Consequently, we have no basis from which to estimate either the duration or ultimate outcome of these investigations. Additional lawsuits may arise from the Multi-State Investigation which may or may not name the Company, the Bank or any of their current subsidiaries as parties to these suits. As with the Illinois lawsuit described above, the Bank is not responsible for any of the alleged conduct in the Multi-State Investigation or any claims that may arise from related lawsuits. As contemplated by the Separation and Distribution Agreement relating to, and the structure of, the Spin-Off, Navient is legally responsible for, has assumed, and has accepted responsibility to indemnify the Company against, all costs, expenses, losses and remediation that may arise from these matters.
With regard to the CFPB Investigation, we note that on January 18, 2017, the CFPB filed a complaint in federal court in Pennsylvania against Navient, along with its subsidiaries, Navient Solutions, Inc. and Pioneer Credit Recovery, Inc. The complaint alleges these Navient entities, among other things, engaged in deceptive practices with respect to their historic servicing and debt collection practices. Neither SLM, the Bank, nor any of their current subsidiaries are named in, or otherwise a party to, the lawsuit and are not alleged to have engaged in any wrongdoing. The CFPB’s complaint asserts Navient’s assumption of these liabilities pursuant to the Separation and Distribution Agreement.
