Diluted earnings per share are computed using the weighted-average number of common shares and dilutive potential common shares outstanding during the period. Dilutive potential common shares result from the assumed exercise of outstanding stock options and unvested restricted stock, by application of the treasury stock method that have a dilutive effect on earnings per share and the notional shares of the Company in the West Corporation Nonqualified Deferred Compensation Plan. At December 31, 2015, 2014 and 2013, 2,210,894, 623,670 and 713,662 stock options were outstanding, respectively, with an exercise price equal to or exceeding the market value of our common stock that were therefore excluded from the computation of shares contingently issuable upon exercise of the options.
