Net Income Per Share |
Net Income Per Share | ​ ​ (17) Net Income Per Share ​ Basic net income per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted-average number of common shares outstanding during the period and, if dilutive, potential common shares outstanding during the period. The Company’s potential common shares consist of the incremental common shares issuable upon the exercise of stock options, the release of restricted stock units and the shares purchasable via the employee stock purchase plan as of the balance sheet date. ​ The following table presents the calculation of basic and diluted net income per share: ​
