Net Earnings (Loss) Per Share
Net Earnings (Loss) Per Share
The Company calculates basic net EPS using net earnings and the weighted-average number of shares outstanding during the reporting period. Diluted net EPS includes the weighted-average dilutive effect of restricted stock awards, stock options, and performance-based awards.
The reconciliations of the numerators and denominators of each of the basic and diluted net EPS calculations were as follows:

(1)
U.S. GAAP requires the denominator used in the diluted EPS calculation for discontinued operations to be the same as that of continuing operations, regardless of net earnings (loss) from continuing operations.
(2)
The Company excludes shares potentially issuable under employee stock plans that could dilute basic EPS in the future from the calculation of diluted net earnings (loss) per share, as their effect, if included, would have been anti-dilutive for the periods presented.
