Earnings Per Share [Text Block] | Note 5. Income (Loss) Per Common Share We are authorized to issue 500,000,000 shares of common stock, $0.25 par value per share. At June 30, 2016, there were 388,800,542 shares of our common stock issued and 3,733,742 shares issued and held in treasury, for a net of 385,066,800 shares outstanding. For the three-month and six-month periods ended June 30, 2015, all outstanding options, restricted share units, and warrants were excluded from the computation of diluted loss per share, as our reported net losses for those periods would cause their conversion and exercise to have no effect on the calculation of loss per share. For the three-month and six-month periods ended June 30, 2016, 3,515,356 restricted stock units that are unvested or vested in the current period are included in the calculation of diluted income per share. There were no options outstanding as of June 30, 2016.
