Earnings Per Share [Abstract]
Earnings Per Share	NOTE 5. Earnings Per Share Basic earnings (loss) per share is computed by dividing income (loss) available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings (loss) per share is computed similarly to basic earnings (loss) per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential additional common shares that were dilutive had been issued as determined by using the treasury stock method. Common share equivalents are excluded from the computation if their effect is anti-dilutive. The Company’s common share equivalents consist of convertible preferred stock, stock options and warrants. Common shares from the potential exercise of certain options and warrants are excluded from the computation of diluted earnings (loss) per share if their exercise prices are greater than the Company’s average stock price for the period. For the transition period from January 1, 2020 to February 1, 2020, the number of such shares excluded was 2,128,000. For both the 13 and 39-week periods ended October 31, 2020, the number of such shares excluded was 2,293,000. For the three and nine-month periods ended September 30, 2019, the number of such shares excluded was 569,000 and 560,000, respectively. For the 39-week period ended October 31, 2020, the dilutive effect of in-the-money warrants amounted to 312,000 shares. For the transition period from January 1, 2020 to February 1, 2020, the number of in-the-money warrants and preferred shares excluded from the computation of net loss per share because their inclusion would have been anti-dilutive amounted to 1,003,000. For the 13-week period ended October 31, 2020, the number of in-the-money warrants and preferred shares excluded from the computation of net loss per share amounted to 702,000. For the three and nine‑month periods ended September 30, 2019, the number of in-the-money warrants and preferred shares excluded from the computation of net loss per share amounted to 3,000 and 12,000.

NOTE 5. Earnings Per Share

Basic earnings (loss) per share is computed by dividing income (loss) available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings (loss) per share is computed similarly to basic earnings (loss) per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential additional common shares that were dilutive had been issued as determined by using the treasury stock method. Common share equivalents are excluded from the computation if their effect is anti-dilutive. The Company’s common share equivalents consist of convertible preferred stock, stock options and warrants.

Common shares from the potential exercise of certain options and warrants are excluded from the computation of diluted earnings (loss) per share if their exercise prices are greater than the Company’s average stock price for the period. For the transition period from January 1, 2020 to February 1, 2020, the number of such shares excluded was 2,128,000. For both the 13 and 39-week periods ended October 31, 2020, the number of such shares excluded was 2,293,000. For the three and nine-month periods ended September 30, 2019, the number of such shares excluded was 569,000 and 560,000, respectively. For the 39-week period ended October 31, 2020, the dilutive effect of in-the-money warrants amounted to 312,000 shares. For the transition period from January 1, 2020 to February 1, 2020, the number of in-the-money warrants and preferred shares excluded from the computation of net loss per share because their inclusion would have been anti-dilutive amounted to 1,003,000. For the 13-week period ended October 31, 2020, the number of in-the-money warrants and preferred shares excluded from the computation of net loss per share amounted to 702,000. For the three and nine‑month periods ended September 30, 2019, the number of in-the-money warrants and preferred shares excluded from the computation of net loss per share amounted to 3,000 and 12,000.
