Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share Basic net income per share is calculated by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share assumes the conversion of all potentially dilutive securities and is calculated by dividing net income by the sum of the weighted average number of shares of common stock outstanding plus all potentially dilutive securities. Dilutive common shares consist primarily of stock options and restricted stock awards. ASU 2016-09 impacts the calculation of diluted weighted average shares under the treasury stock method as the Company no longer increases or decreases the assumed proceeds from an employee vesting in, or exercising, a share-based payment award by the amount of excess tax benefits or deficiencies taken to additional paid-in capital.
