Earnings Per Share [Abstract]

EARNINGS PER SHARE [Text Block]

EARNINGS PER SHARE:

Basic earnings (loss) per share are calculated by dividing net income (loss) by the weighted-average shares of common stock outstanding during the period. Diluted earnings (loss) per share are calculated by dividing net income (loss) by the weighted-average shares of common stock and dilutive common equivalent shares outstanding during the period. Dilutive common equivalent shares included in this calculation consist of dilutive shares issuable upon the assumed exercise of outstanding common stock options, the assumed vesting of outstanding restricted stock units and performance based awards, and the assumed issuance of awards under the stock purchase plan, as computed using the treasury stock method.

A summary of the earnings (loss) per share calculation is as follows (in thousands, except per share amounts):

_______________ 

(1) The Company includes the shares underlying performance-based awards in the calculation of diluted earnings per share if the performance conditions have been satisfied as of the end of the reporting period and excludes such shares when the necessary conditions have not been met. The Company has included the shares underlying the 2013 and 2012 awards in the 2013 and 2012 calculations, respectively, as those shares were contingently issuable upon the satisfaction of the annual targets consisting of net revenue, non-GAAP operating earnings and achievement of strategic goals as of the end of the periods.  The Company has excluded all performance-based awards underlying the 2011 awards in the 2011 calculation as the performance conditions for those awards were not met as of the end of the period.

In the years ended December 31, 2013, and 2011 options to purchase 122,263 shares and 294,965 shares outstanding, respectively, were not included in the computation of diluted earnings per share for the periods then ended because they were determined to be anti-dilutive. In the year ended December 31, 2012, all shares attributable to stock-based awards were excluded in the computation of diluted earnings per share, as the Company was in a net loss position.
