The following are significant items or events that occurred in the third-quarter 2020 and will affect the company’s performance in 2020.

Impact of COVID-19 on Sallie Mae
During the third quarter of 2020, economic and consumer trends appeared to be slightly improving and progress was made on vaccine trials and possible treatments to mitigate the spread of the COVID-19 virus. However, the absence of actions by the U.S. government to pass further economic relief legislation and the threat of a “second-wave” of COVID-19 infections in the fourth quarter of 2020 led to continued uncertainty in the economy. For the quarter ended Sept. 30, 2020, the company considered the current economic forecasts as well as how the significant uncertainty may affect future unemployment rates and the economy in estimating the company’s allowance for credit losses. We remain cautious about the near term economic forecasts and have not changed the economic scenarios used in determining the allowance for credit losses in the third quarter of 2020 from the scenarios used in the second quarter of 2020. Provisions for credit losses in the current quarter decreased by $103 million compared with the year-ago quarter. During the third quarter of 2020, the provision for credit losses was affected by a benefit of $98 million from improvements in the economic forecasts used compared to the second quarter of 2020, a benefit of $68 million from faster prepayment speeds, and a benefit of $43 million from the sale of our Personal Loan portfolio. The benefit from the economic forecasts was heavily influenced by a recalibration of the college graduate unemployment rate that occurred in the third quarter of 2020. The benefit from faster prepayment speeds was to reflect actual loan prepayment speeds being higher than what our models were predicting due to the significant amount of COVID-19 related government stimulus. These benefits were mostly offset by $129 million in additional provision for new commitments to lend that were entered into during the quarter, and other factors. As the year progresses and COVID-19’s economic impact becomes clearer, the company could experience significant changes in its allowance for loan losses. For further discussion of the risk COVID-19 poses to the business, the company’s response to the pandemic, and the expected impacts of COVID-19 on the business, please refer to the company’s quarterly report on Form 10-Q for the fiscal quarter ended Sept. 30, 2020 (filed with the Securities and Exchange Commission (“SEC”) on Oct. 21, 2020). The COVID-19 crisis is unprecedented and has had a significant impact on the economic environment globally and in the U.S. There is a significant amount of uncertainty as to the length and breadth of the impact to the U.S. economy and, consequently, on the company. Please refer to Part II, Item 1A. “Risk Factors — COVID-19 Pandemic” in the company’s quarterly report on Form 10-Q for the fiscal quarter ended March 31, 2020 (filed with the SEC on April 22, 2020), for risks associated with COVID-19. Also, see page 6 for a cautionary note regarding 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 the company’s Annual Report on Form 10-K for the year ended Dec. 31, 2019 (filed with the SEC on Feb. 28, 2020) and subsequent filings with the SEC.

Restructuring Activities
During the third quarter of 2020, the company initiated a restructuring program to reduce costs and improve operating efficiencies by better aligning its organizational structure with its new corporate strategic initiatives. In conjunction with these restructuring plans, involuntary termination benefit arrangements and certain other costs that are incremental and incurred as a direct result of our restructuring plan are classified as restructuring expenses in the accompanying consolidated statements of income. Restructuring expenses of $24 million were recorded in the three and nine months ended Sept. 30, 2020. For further discussion of the company’s new strategic imperatives and restructuring activities, please refer to the company’s quarterly report on Form 10-Q for the fiscal quarter ended Sept. 30, 2020 (filed with the SEC on Oct. 21, 2020).

Sale of Personal Loan Portfolio
At the end of 2019, the company announced the ceasing of personal loan purchases and originations. In the third quarter of 2020, the entire personal loan portfolio, including $697 million of principal and $7 million in accrued interest, was sold, resulting in a $43 million reduction to the company’s provision for credit losses. This opportunity was taken to reduce the risk to the balance sheet and focus our capital and attention on the core student loan business.

Guidance
Given the economic uncertainties resulting from COVID-19, the company withdrew guidance for 2020 earlier in 2020.

Footnotes:
(1) Sallie Mae provides “Core Earnings” because it is one of several measures management uses to evaluate management performance and allocate corporate resources. The difference between “Core Earnings” and GAAP net income is driven by mark-to-fair value unrealized gains and losses on derivative contracts recognized in GAAP, but not in “Core Earnings” results. See the “Core Earnings” to GAAP Reconciliation in this press release for a full reconciliation of GAAP and “Core Earnings.” “Core Earnings” exclude periodic unrealized gains and losses caused by the mark-to-fair value valuations on derivatives that do not qualify for hedge accounting treatment under GAAP, but include current period accruals on the derivative instruments. Under GAAP, for our derivatives held to maturity, the cumulative net unrealized gain or loss over the life of the contract will be equal to $0. Management believes the company’s derivatives are effective economic hedges, and, as such, they are a critical element of the company’s interest rate risk management strategy. Our “Core Earnings” are not defined terms within GAAP and may not be comparable to similarly titled measures reported by other companies.
(2) We calculate and report our Return on Assets (“ROA”) as the ratio of (a) GAAP net income (loss) numerator (annualized) to (b) the GAAP total average assets denominator.
(3) We calculate and report our non-GAAP “Core Earnings” Return on Assets (“Core Earnings ROA”) as the ratio of (a) “Core Earnings” net income (loss) numerator (annualized) to (b) the GAAP total average assets denominator.
(4) We calculate and report our Return on Common Equity (“ROCE”) as the ratio of (a) GAAP net income (loss) attributable to common stock numerator (annualized) to (b) the net denominator, which consists of GAAP total average equity less total average preferred stock.
(5) We calculate and report our non-GAAP “Core Earnings” Return on Common Equity (“Core Earnings ROCE”) as the ratio of (a) “Core Earnings” net income (loss) attributable to common stock numerator (annualized) to (b) the net denominator, which consists of GAAP total average equity less total average preferred stock.

______
(1) Derivative Accounting: “Core Earnings” exclude periodic unrealized gains and losses caused by the mark-to-fair value valuations on derivatives that do not qualify for hedge accounting treatment under GAAP, but include current period accruals on the derivative instruments. 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 Sallie Mae Bank where the derivative instruments are held.
The following table reflects our provisions for credit losses and total portfolio net charge-offs:

|  | Three Months Ended |  |  |  | Nine Months Ended |  |
|  | September 30, |  |  |  | September 30, |  |
(Dollars in thousands) |  | 2020 |  | 2019 |  | 2020 |  | 2019
Provisions for credit losses |  | $ | (3,640) |  |  | $ | 99,526 |  |  | $ | 409,505 |  |  | $ | 256,691 |
Total portfolio net charge-offs |  | (53,770) |  |  | (67,905) |  |  | (154,838) |  |  | (183,604) |

In 2020, we began to evaluate management’s performance internally using a measure that starts with “Core Earnings” net income as disclosed above for a period, and further adjusting it by increasing it by the impact of GAAP provisions for credit losses and decreasing it by the total portfolio net charge-offs recorded in that period, net of the tax impact of these adjustments.
