Note 5. | Income (Loss) Per Common Share
We are authorized to issue 750,000,000 shares of common stock, $0.25 par value per share. At June 30, 2017, there were 402,957,303 shares of our common stock issued and 4,429,844 shares issued and held in treasury, for a net of 398,527,459 shares outstanding. Diluted income (loss) per share for the three and six months ended June 30, 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 -month period ended June 30, 2017, all restricted share units and deferred shares were excluded from the computation of diluted loss per share, as our reported loss for that period would cause them to have no effect on the calculation of loss per share. For the six -month period ended June 30, 2017, 3,619,975 restricted stock units that were unvested or which vested in the current period and 1,352,470 deferred shares were included in the calculation of diluted income per share. For the three -month and six -month periods ended June 30, 2016, 3,515,356 restricted stock units that were unvested or which vested in the current period and 635,602 deferred shares were included in the calculation of diluted income per share. There were no options or warrants outstanding as of June 30, 2017 or June 30, 2016.
