Net Income/(Loss) Per Share of Common Stock

Note L – Net Income/(Loss) Per Share of Common Stock

Basic net income/(loss) per share is based on the weighted average number of shares of common stock outstanding during the period, which does not include unvested restricted common stock subject to forfeiture of 2,849, 3,651 and 4,427 shares for the years ended December 31, 2021, 2020 and 2019, respectively. Diluted net income per share reflects: a) the potential dilution assuming shares of common stock were issued upon the exercise of outstanding in-the-money options and the assumed proceeds, which are deemed to be the proceeds from the exercise plus compensation cost not yet recognized attributable to future services using the treasury method, were used to purchase shares of the Company’s common stock at the average market price during the period, and b) the vesting of granted non-vested restricted stock awards for which the assumed proceeds upon vesting are deemed to be the amount of compensation cost not yet recognized attributable to future services using the treasury stock method, to the extent dilutive.

Diluted	81,628	78,635	83,646

The year ended December 31, 2020 resulted in a net loss; therefore, there was no difference in the weighted average number of common shares for basic and diluted loss per share as the effect of all potentially dilutive shares outstanding was anti-dilutive. For the years ended December 31, 2021, 2020 and 2019, options to purchase approximately 5, 89 and 5 shares of common stock, respectively, have been excluded from the calculation of diluted net (loss)/income per share, as the result would have been anti-dilutive. For the year ended December 31, 2021 and 2020, 7 and 2,524 restricted shares were excluded from the calculation of diluted net (loss) per share, as the result would have been anti-dilutive. For the years ended December 31, 2019, all unvested restricted stock awards were dilutive. The Company had contingently issuable performance awards outstanding that did not meet the performance conditions as of year ended December 31, 2021 and, therefore, were excluded from the

calculation of diluted net income/(loss) per common share for the year ended December 31, 2021 and 2020. The maximum number of potentially dilutive shares that could be issued upon vesting for these performance awards was approximately 17,000 and 300,000 as of December 31, 2021 and 2020, respectively. These amounts were also excluded from the computation of weighted average potentially dilutive securities.
