Earnings Per Share [Abstract] |
Earnings Per Share [Text Block] | Note 5. 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, 2014, there were 350,156,592 shares of our common stock issued and 1,466,611 shares issued and held in treasury, for a net of 348,689,981 shares outstanding. The following table reconciles weighted average common shares used in the computations of basic and diluted earnings per share for the three- and six-month periods ended June 30, 2014 and 2013 (thousands, except per-share amounts):

Diluted loss per share for the three- and six-month periods ended June 30, 2014 and 2013 excludes the potential effects of outstanding shares of our convertible preferred stock, as their conversion and exercise would have no effect on the calculation of dilutive shares. For the three-month and six-month periods ended June 30, 2014 and 2013, 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.
