Basic net income per common share is computed by dividing net income by the average common shares outstanding for the period. Diluted net income per common share reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted. The dilutive effect of outstanding options and restricted share units is reflected in diluted net income per common share, unless the impact is anti-dilutive, by application of the treasury stock method.
As of March 31, 2017 and 2016, there were 2.2 million and 2.5 million, respectively, potentially dilutive shares related to Warrants and stock options to purchase shares of common stock that were outstanding during 2017 and 2016, but were not included in the computation of diluted net income per common share because the effect would have been anti-dilutive.
