Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per ShareBasic earnings per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted earnings per share is applicable only in periods of net income and is computed by dividing net income by the weighted average number of common shares outstanding for the period, inclusive of potentially dilutive common shares outstanding for the period. Periods of net loss require the diluted computation to be the same as the basic computation. There were no potentially dilutive common shares outstanding during fiscal years 2019 and 2020. There was an aggregate of 0.9 million potentially dilutive common share equivalents outstanding during fiscal year 2021, but were not included in the computation of diluted earnings per share because their effect would have been anti-dilutive.
