Earnings Per Share [Abstract]
Earnings Per Share	NOTE 4. Earnings Per Share Basic earnings (loss) per share are computed by dividing income (loss) available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings (loss) per share are 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. 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 three-month periods ended March 31, 2019 and 2018, the number of such shares excluded were 4,971,000 and 423,000, respectively. For the three-month period ended March 31, 2019, the number of in-the-money warrants excluded from the computation of net loss per share because their inclusion would have been anti-dilutive amount to 93,000, and the number of preferred shares excluded was 322,000. There were no in-the-money options or warrants for the three-month period ended March 31, 2018 that were required to be excluded from the computation of net loss per share, but the number of preferred shares excluded was 764,000. All share and per share numbers in this report have been retroactively restated for the Company’s reverse stock split effected in March 2018.

NOTE 4. Earnings Per Share

Basic earnings (loss) per share are computed by dividing income (loss) available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings (loss) per share are 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. 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 three-month periods ended March 31, 2019 and 2018, the number of such shares excluded were 4,971,000 and 423,000, respectively. For the three-month period ended March 31, 2019, the number of in-the-money warrants excluded from the computation of net loss per share because their inclusion would have been anti-dilutive amount to 93,000, and the number of preferred shares excluded was 322,000. There were no in-the-money options or warrants for the three-month period ended March 31, 2018 that were required to be excluded from the computation of net loss per share, but the number of preferred shares excluded was 764,000.

All share and per share numbers in this report have been retroactively restated for the Company’s reverse stock split effected in March 2018.
