| Earnings Per Common Share |
2. Earnings Per Common Share
Basic earnings per share is the amount of earnings (adjusted for dividends declared on our preferred stock) available to each Common Share outstanding during the reporting periods. Diluted earnings per share is the amount of earnings available to each Common Share outstanding during the reporting periods adjusted to include the effects of potentially dilutive Common Shares. Potentially dilutive Common Shares include stock options and other stock-based awards. Potentially dilutive Common Shares are excluded from the computation of diluted earnings per share in the periods where the effect would be antidilutive.
Our basic and diluted earnings per Common Share are calculated as follows: | | | | | | | | | | | | | | | | Three months ended September 30, | | Nine months ended September 30, | dollars in millions, except per share amounts | 2018 |
