Schedule of Weighted Average of Potential Class A Common Stock Excluded from Computation of Earnings (Loss) Per Share

For the three and six months ended June 30, 2023 and 2022, the following weighted average shares of potential class A common stock were excluded from the diluted earnings (loss) per share calculation because their impact would have been anti-dilutive (in thousands):

Tabular disclosure of securities (including those issuable pursuant to contingent stock agreements) that could potentially dilute basic earnings per share (EPS) in the future that were not included in the computation of diluted EPS because to do so would increase EPS amounts or decrease loss per share amounts for the period presented, by antidilutive securities.
