Earnings Per Share [Text Block] | Note 5. Loss Per Common Share We are authorized to issue 750,000,000 shares of common stock, $0.25 par value per share. At September 30, 2019, there were 496,538,038 shares of our common stock issued and 6,287,271 shares issued and held in treasury, for a net of 490,250,767 shares outstanding. Basic and diluted loss per common share, after preferred dividends, was $(0.04) and $(0.19) for the three- and nine-month periods ended September 30, 2019, respectively. Basic and diluted loss per common share, after preferred dividends, was $(0.05) and $(0.01) for the three- and nine-month periods ended September 30, 2018, respectively. Diluted loss per share for the three and nine months ended September 30, 2019 and 2018 excludes the potential effects of outstanding shares of our convertible preferred stock, as their conversion would have no effect on the calculation of dilutive shares. For the three-month and nine-month periods ended September 30, 2019 and 2018, all restricted share units, deferred shares and warrants were excluded from the computation of diluted loss per share, as our reported loss for those periods would cause them to have no effect on the calculation of loss per share.
