(1) For each year presented, Mr. Patrick W. Smith was our principal executive officer (PEO); reflects amounts reported in the Summary Compensation Table (“SCT”) for the respective years. Our non-PEO NEOs for 2022 were Ms. Bagley and Messrs. Isner, Kunins, Larson, Ahsan, and Zito. Our non-PEO NEOs for 2021 and 2020 were Messrs. Larson, Ahsan, Isner, and Kunins. Average compensation for the non-PEO NEOs reflects amounts reported in the SCT for the respective years.

(2) Amounts shown for compensation actually paid (“CAP”) are computed in accordance with Item 402(v) of Regulation S-K under the Exchange Act and do not reflect the actual amount of compensation earned by or paid to the NEOs during the applicable year. These amounts reflect total compensation as reported in the SCT with certain adjustments as required by item 402(v) of Regulation S-K as described in footnote (3) below.

(3) CAP reflects the exclusions and inclusions of equity awards for the PEO and the other NEOs as set forth below and calculated in accordance with FASB ASC Topic 718, Compensation - Stock Compensation. The valuation methodologies and assumptions used to calculate CAP are based on the grant date fair value of these awards as disclosed in the company’s consolidated audited financial statements filed with the SEC on Form 10-K for the years reflected in the table below:

Compensation Actually Paid	$	31,929,509	$	30,194,861	$	2,091,584

(a) For the PEO and other NEOs, for each covered year, fair value of awards that are granted and vest in the same covered fiscal year equals $0, and fair value of awards granted in prior years that are determined to fail to meet the applicable vesting conditions during the covered fiscal year equals $0.

(b) The amount shown for 2020 represents the total stock compensation expense for modified shares related to a PSU award for Mr. Smith. See the SCT for more information.

(4) TSR shown in this table utilizes the Russell Midcap Index which we use in the stock performance graph required by Item 201(e) of Regulation S-K included in the company’s consolidated audited financial statements filed with the SEC on Form 10-K for the years reflected in the table above. The comparison assumes $100 was invested for the period starting December 31, 2019 through December 31 of the applicable fiscal year in each of the company’s Common Stock and the Russell Midcap Index. All dollar values assume reinvestment of the pre-tax value of dividends paid by companies included in the Russell Midcap Index. The historical stock price performance of our Common Stock shown is not necessarily indicative of future stock price performance.

(5) Pursuant to Item 402(v) of Regulation S-K, we determined adjusted EBITDA to be the most important financial performance measure used to link company performance to CAP to our PEO and other NEOs in 2022. 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 such measure in future years. Adjusted EBITDA is defined as Adjusted EBITDA (Most comparable GAAP Measure: Net income) - Earnings before interest expense, investment interest income, taxes, depreciation, amortization and non-cash stock-based compensation expense, realized and unrealized gains and losses on strategic investments and marketable securities, and certain other pre-tax items. For a reconciliation of Adjusted EBITDA to earnings, see “Fiscal 2022 Company Highlights and Compensation Overview” above.
