Net Income Per Share

5. NET INCOME PER SHARE

Basic net income per share is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding. Common shares outstanding includes common stock issued plus restricted stock units for which no future service is required as a condition to the delivery of the underlying common stock less treasury shares. Diluted net income per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding plus all dilutive potential common shares outstanding during the period. All dilutive potential common shares outstanding consider common stock deliverable pursuant to nonvested restricted stock units. These dilutive shares totaled 109,738 and 114,269 from the assumed settlement of diluted nonvested restricted stock units at March 31, 2013 and 2012, respectively. The following table presents securities outstanding that could potentially dilute basic EPS in the future that were not included in the computation of diluted EPS because they were antidilutive for years ended March 31, 2013 and 2012:

In connection with Ambac’s emergence from bankruptcy in the second quarter of 2013, Ambac’s pre-Effective Date common stock and equity interests, including stock options, warrants and other rights to acquire shares, have been cancelled. Accordingly, the stock options and restricted stock units referenced in the table above will not be antidilutive to the new common stock that was issued in May 2013.
