Earnings Per Share

12 Months Ended

Jun. 30, 2022

Basic earnings (loss) per common share is computed by dividing net earnings (loss) available to common shareholders by the weighted-average number of shares of common stock outstanding during the period.

The diluted earnings (loss) per common share is computed by dividing the diluted earnings (loss) available to common shareholders by the weighted-average number of shares of common stock and potentially dilutive shares of common stock

outstanding during the period. The dilutive effect of equity awards is calculated based on the average stock price for each fiscal period, using the treasury stock method. For the fiscal years ended June 30, 2022 and June 30, 2021, diluted shares outstanding include the dilutive effect of the potential shares of the Company's common stock issuable from stock options, performance and restricted shares. For the fiscal year ended June 30, 2022 and June 30, 2021, the diluted shares outstanding also include the dilutive effect of the potential shares of the Company's common stock issuable upon conversion of outstanding convertible debt.

The following is a reconciliation of the numerators and denominators of the basic and diluted earnings (loss) per share computations for the periods presented ($000):
