Earnings Per Share

(15)  EARNINGS PER SHARE

The following table summarizes the computations of basic earnings per share (“Basic EPS”) and diluted earnings per share (“Diluted EPS”). Basic EPS is computed as net income divided by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur from common shares issuable through stock-based compensation plans including stock options, restricted stock, restricted stock units, ESPP purchase rights, warrants, and other convertible securities using the treasury stock method.

For the fiscal years ended March 31, 2017 and 2016, an immaterial amount of options to purchase, restricted stock units and restricted stock to be released were excluded from the treasury stock method computation of diluted shares as their inclusion would have had an antidilutive effect.

For the fiscal year ended March 31, 2015, stock options to purchase, restricted stock units and restricted stock to be released in the amount of 3 million shares were excluded from the treasury stock method computation of diluted shares as their inclusion would have had an antidilutive effect.
