| Add: Weighted-average stock options(b) |  |  | 6 |  |  | 7 |  |  | 6
| Diluted |  |  | 1,051 |  |  | 1,089 |  |  | 1,141

The Company’s unvested restricted stock awards, which include the right to receive non-forfeitable dividends or dividend equivalents, are considered participating securities. Calculations of EPS under the two-class method exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities. The related participating securities are similarly excluded from the denominator. T he dilutive effect of unexercise d stock options excludes 0.2 million, 0.1 million and 7.6 million options from the computation of EPS f or the years ended December 31, 2014, 2013 and 2012, respectively, because inclusion of the options would have been anti-dilutive. For the years ended December 31, 2014, 2013 and 2012, the Company met specified performance measures related to the Subordinated D ebentures of $750 million issued in 2006, and maturing in 2036. If the performance measur es were not achieved in any given quarter, the Company would be required to issue common shares and apply the proceeds to make interest payments.
