Computation of Earnings Per Share
COMPUTATION OF EARNINGS PER SHARE

The computation of basic earnings per share is based on net earnings divided by the weighted average number of shares of common stock outstanding for each year. The computation of diluted earnings per share includes the common stock equivalency of dilutive options granted to employees under the Company's stock incentive plan and shares issuable on redemption of its Convertible Notes.

Equity awards

Excluded from the diluted earnings per share calculation for the years ended December 31, 2016, 2015 and 2014, respectively, are 472,328, 487,071 and 342,994 shares associated with equity awards granted to employees that are anti-dilutive based on the average stock price.

Convertible Notes

For the years ended December 31, 2016, 2015 and 2014, shares issuable under the Convertible Notes that were dilutive during the period were included in the calculation of earnings per share as the conversion price for the Convertible Notes was less than the average share price of the Company's stock.

Warrants

Excluded from the diluted earnings per share calculation for the years ended December 31, 2016, 2015 and 2014, respectively were 3,383,826, 3,422,477, and 3,411,539 shares, issuable under the warrants sold in connection with the Company’s Convertible Note offering as they would be anti-dilutive.
