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 from the computation of EPS 0.5 million, 0.2 million and 0.1 million of options f or the years ended December 31, 2015, 2014 and 2013, respectively, because inclusion of the options would have been anti-dilutive. For the years ended December 31, 2015, 2014 and 2013, the Company met specified performance measures related to the $750 million of Subordinated Debentures 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.
