EARNINGS PER SHARE

Share-based awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are participating securities and included in the computation of both basic and diluted earnings per share. Our grants of restricted stock awards to our employees and directors are considered participating securities and we have prepared our earnings per share calculations to exclude outstanding unvested restricted stock awards, using the two-class method, in the basic and diluted weighted average shares outstanding calculation.

The following table sets forth the computation of the basic and diluted earnings per share for the years ended December 31, 2013, 2014 and 2015:

The fully diluted weighted average shares outstanding for the year ended December 31, 2015, and the corresponding calculation of fully diluted earnings per share, included approximately 0.3 million shares that would have been issued upon the conversion of our convertible subordinated notes as a result of the application of the if-converted method prescribed by the FASB ASC 260. There were no shares for the year ended December 31, 2014 that would have been issued upon conversion under the if-converted method for our convertible subordinated notes.

The fully diluted weighted average shares outstanding for the year ended December 31, 2013, and the corresponding calculation of fully diluted earnings per share, included approximately 4.4 million shares that would have been issued upon conversion of our convertible junior subordinated debentures as a result of the application of the if-converted method prescribed by ASC 260. The convertible junior subordinated debentures were redeemed in March and April 2014. As a result, there was no impact on our calculation of fully diluted earnings per share for the years ended December 31, 2014 and 2015.

Options to purchase 0.5 million shares were not included in the computation of diluted earnings per share for the year ended December 31, 2013, because the effect would be anti-dilutive as the exercise prices exceeded the average market price of the common shares. There were no options excluded in the computation of diluted earnings per share for the years ended December 31, 2014 and 2015.
