Note 14	Earnings (Loss) Per Share

Basic net income (loss) per share (EPS) is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income (loss) by the weighted average number of common and dilutive potential common shares outstanding during the period. Basic and diluted EPS (in thousands, except per share amounts):

During the quarter and nine months ended September 30, 2017, 5.3 million and 5.2 million shares of common stock, respectively, of potentially issuable shares from stock awards were excluded from the calculation of diluted EPS because of their antidilutive effect.

During the quarter and nine months ended September 30, 2016, 4.6 million and 4.8 million shares of common stock, respectively, of potentially issuable shares from stock awards were excluded from the calculation of diluted EPS because of their antidilutive effect.
