(2)	The amounts shown for Compensation Actually Paid have been calculated in accordance with Item 402(v) of Regulation S-K and do not reflect compensation actually earned, realized, or received by the Company’s NEOs. These amounts reflect the Summary Compensation Table Total on page 79 with certain adjustments as described in footnote 3 below.

(3)	Compensation Actually Paid does not necessarily represent cash and/or equity value transferred to the applicable named executive officer without restriction, but rather is a valuation that reflects the exclusions and inclusions of certain amounts for the PEO and the non-PEO NEOs as set forth below. Equity values are calculated in accordance with FASB ASC Topic 718. Amounts in the Exclusion of Stock Awards column are the totals from the Stock Awards columns set forth in the Summary Compensation Table.

(a)

This column includes the year-end value of the portion(s) of performance stock unit awards approved in a prior year with a grant date in the current reporting year when the “Core Earnings” Return on Equity measure for that portion is established. See discussion of our Long-term Incentive Program in the Compensation Discussion and Analysis above.

(4)	The Peer Group TSR set forth in this table utilizes the S&P 400 Financials Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our 2022 Annual Report. The comparison assumes $100 was invested for the period starting December 31, 2019, through the end of the listed year in the Company and in the S&P 400 Financials Index, respectively.

(5)	We determined Cumulative Net Student Loan Cash Flows to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and other non-PEO NEOs in 2022. Cumulative Net Student Loan Cash Flows is a non-GAAP financial measure that does not represent a comprehensive basis of accounting. This performance measure may not have been the most important financial performance measure for years 2021 and 2020 and we may determine a different financial performance measure to be the most important financial performance measure in future years. For more information on the definition of Cumulative Net Student Loan Cash Flows, please refer to the definition at footnote 18.
