Income (Loss) and Dividends per Common Share

Basic income (loss) per share is based on the weighted average number of common shares outstanding. Diluted income per share assumes exercise of stock options in all periods, provided the effect is not antidilutive. The per share calculations below exclude 5 million and 6 million of stock options for the three and nine months period ended September 30, 2018 and 10 million and 11 million stock options for the three and nine months period ended September 30, 2017 that were antidilutive.
