For comparison purposes, the following table shows two other TSR calculations based on (A) a per share price of $4.52, the 409A valuation of a share of common stock on December 31, 2019 and (B) on a per share price of $19.00, the target price of our common stock in our IPO. The closing price of our common stock was $87.29, $91.27, and $63.56 on December 31, 2020, December 31, 2021 and December 30, 2022, respectively.

No portion of NEO compensation is directly dependent upon our net income (loss) for the years presented; however, SEC rules require that net income be presented as a performance measure in this table. (7) This column shows our actual revenue for each year covered by the table. We consider revenue to be a key metric in our executive compensation program, as this is the primary financial metric used in determining payouts under our annual cash bonus program. See the Compensation Discussion and Analysis section for more information regarding the use of this performance measure in our executive compensation program. | ||
