The following table shows the total compensation for our NEOs for the past three fiscal years as set forth in the Summary Compensation Table, the “Compensation Actually Paid” to our CEO (also referred to as the principal executive officer (“PEO”)) and, on an average basis, our non-PEO NEOs and Company performance for the fiscal years listed below, our Total Shareholder Return (“TSR”), the TSR of the Nasdaq Computer Index (“Peer Group TSR”), and our company-selected measure for 2022, SaaS Revenue. The Compensation Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the years shown.

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 with certain adjustments as described in footnote 3 below. 3. Amounts in this column represent the Compensation Actually Paid in the indicated fiscal years to the PEO and, on an average basis, the non-PEO NEOs, based on their total compensation reported in the Summary Compensation Table for the indicated fiscal years and adjusted as set forth below. Equity values are calculated in accordance with FASB ASC Topic 718.

The Peer Group TSR set forth in this table utilizes the Nasdaq Computer Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended December 31, 2022. The comparison assumes $100 was invested for the period starting October 1, 2020, the date our common stock commenced trading on Nasdaq after our direct listing, through the end of the listed year in the Company and in the Nasdaq Computer Index, respectively. Historical stock performance is not necessarily indicative of future stock performance. 5. We determined SaaS Revenue to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs in 2022. SaaS Revenue by business segment is listed in Item 7 our annual report filed on Form 10-K for the most recent fiscal year; the sum of the SaaS Revenue by business segment equals the amount shown in the table above. 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. | ||
