Earnings Per Share [Abstract]
Earnings Per Share	NOTE 4. Earnings Per Share Basic earnings per share are computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings per share are computed similarly to basic earnings 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 both the three and nine-month periods ended September 30, 2018, the number of such shares excluded were 164,000. For both the three and nine-month periods ended September 30, 2017, the number of such shares excluded were 43,000. For the three and nine-month periods ended September 30, 2018, 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 4,583,000, and the number of preferred shares excluded was 438,000. There were no in-the-money options or warrants for both the three and nine-month periods ended September 30, 2018 and 2017 that were required to be excluded from the computation of net loss per share.

NOTE 4. Earnings Per Share

Basic earnings per share are computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings per share are computed similarly to basic earnings 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 both the three and nine-month periods ended September 30, 2018, the number of such shares excluded were 164,000. For both the three and nine-month periods ended September 30, 2017, the number of such shares excluded were 43,000. For the three and nine-month periods ended September 30, 2018, 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 4,583,000, and the number of preferred shares excluded was 438,000. There were no in-the-money options or warrants for both the three and nine-month periods ended September 30, 2018 and 2017 that were required to be excluded from the computation of net loss per share.

All share and per share numbers in this report have been retroactively restated for the Company’s two reverse stock splits effected in October 2017 and March 2018.
