Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding for the period. Diluted earnings per share is computed in a similar manner to basic earnings per share after assuming the issuance of shares of common stock for all potentially dilutive equity incentive awards using the treasury stock method.

The following is a reconciliation of net income and the shares of common stock used in the computation of basic and diluted earnings per share:
