Due to the net loss during the three and nine months ended September 30, 2022, the denominator in the diluted earnings per share calculation does not include the effects of the stock awards for which the average market price for the period exceeds the exercise price, as it would result in a less dilutive computation. As a result, reporting diluted earnings per share for the three and nine months ended September 30, 2022 are the same as basic earnings per share.
