Earnings (Loss) Per Share (EPS)

Basic EPS was computed by dividing net income or loss by the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per share was computed under the treasury stock method, assuming the conversion as of the beginning of the period, for all dilutive stock options. Diluted EPS was computed by dividing net income by the sum of the weighted average number of shares of common stock outstanding and potentially dilutive securities outstanding during the period under the treasury stock method. Potentially dilutive securities include stock options and restricted stock units and shares that the Company is contractually obligated to issue in the future.

The following table indicates the computation of basic and diluted earnings per share:

The computation of diluted EPS does not include certain unvested awards, on a weighted average basis, because their inclusion would have an anti-dilutive effect on EPS. The awards excluded because of their anti-dilutive effect were as follows:



	Three Months Ended June 30,		Six Months Ended June 30,
