EARNINGS PER SHARE

Basic earnings per share is calculated on the basis of weighted average outstanding shares of common stock. Diluted earnings per share is computed on the basis of basic weighted average outstanding shares of common stock adjusted for the dilutive effect of stock options, restricted stock unit awards, and other dilutive securities.

The following table reconciles the income and average share amounts used to compute both basic and diluted earnings per share:
