Earnings Per Share [Text Block] | Note 5. Earnings (Loss) Per Common Share We are authorized to issue 500,000,000 shares of common stock, $0.25 par value per share. At March 31, 2017, there were 399,911,009 shares of our common stock issued and 4,085,599 shares issued and held in treasury, for a net of 395,825,410 shares outstanding. Diluted income (loss) per share for the three months ended March 31, 2017 and 2016 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 months ended March 31, 2017, 2,735,569 restricted stock units that were unvested during the quarter and 727,262 in deferred shares were included in the calculation of diluted earnings (loss) per share. For the three -month period ended March 31, 2016, all outstanding restricted share units and warrants were excluded from the computation of diluted earnings (loss) per share, as our reported net loss for that period would cause their vesting and exercise to have no effect on the calculation of earnings (loss) per share. There were no warrants outstanding during the three months ended March 31, 2017.
