Earnings Per Share [Text Block] | Note 5. Earnings (Loss) Per Common Share We are authorized to issue 750,000,000 shares of common stock, $0.25 par value per share. At March 31, 2018, there were 405,166,416 shares of our common stock issued and 4,864,799 shares issued and held in treasury, for a net of 400,301,617 shares outstanding. Basic and diluted income per common share, after preferred dividends, was $0.02 and $0.07 for the three -month periods ended March 31, 2018 and 2017, respectively. Diluted income (loss) per share for the three months ended March 31, 2018 and 2017 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.
