Earnings Per Share [Text Block] | Note 14: Income (Loss) per Common Share We are authorized to issue 750,000,000 shares of common stock, $0.25 par value per share. At December 31, 2018, there were 487,830,728 shares of our common stock issued and 5,226,791 shares issued and held in treasury, for a net of 482,603,937 shares outstanding. We calculate basic earnings per share using, as the denominator, the weighted average number of common shares outstanding during the period. Diluted earnings per share uses, as its denominator, the weighted average number of common shares outstanding during the period plus the effect of potential dilutive common shares during the period using the treasury stock method for options, warrants, and restricted stock units, and if-converted method for convertible preferred shares. Potential dilutive common shares include outstanding restricted stock unit awards, stock units, warrants and convertible preferred stock for periods in which we have reported net income. For periods in which we reported net losses, potential dilutive common shares are excluded, as their conversion and exercise would not reduce earnings per share. Under the if-converted method, preferred shares would not dilute earnings per share in any of the periods presented. A total of 157,816 shares of preferred stock were outstanding at December 31, 2018, 2017 and 2016. The following table represents net income per common share – basic and diluted (in thousands, except earnings per share):

There were no options outstanding for the years ended December 31, 2018, 2017 and 2016, and no warrants outstanding for the years ended December 31, 2017 and 2016. For the years ended December 31, 2018 and 2017, all outstanding restricted stock units, warrants and deferred shares were excluded from the computation of diluted loss per share, as our reported net losses for that period would cause their conversion and exercise to have no effect on the calculation of loss per share. For the year ended December 31, 2016, the calculation of diluted income per common share included (i) 4,309,440 restricted stock units that were unvested or which vested during the year and (ii) 635,602 deferred shares that were dilutive.
