(1)For the years ended December 31, 2022 and December 31, 2020, we excluded from the calculation of diluted loss per share 3.8 million and 5.3 million shares, respectively, potentially issuable under incentive compensation plans or convertible securities, as their effect, if included, would have been anti-dilutive.

Our calculation of diluted (loss) earnings per common share excludes shares of common stock that are issuable upon exercise of stock options when the exercise price is greater than the average market price of our common stock. We also exclude unvested restricted stock awards that are antidilutive as a result of unrecognized compensation cost. Such shares were 13.8 million, 3.2 million and 3.2 million for 2022, 2021 and 2020, respectively.
