Basic and Diluted Per Share Data —

Basic net income per common share is based on the weighted average number of shares of common stock outstanding for the period less restricted stock shares issued in connection with the Company's long-term incentive plans and subject to risk of forfeiture. Diluted net income per common share assumes that outstanding common shares were increased by shares issuable upon (i) vesting of restricted stock shares, and (ii) granting of shares deferred under the long-term incentive plan. Restricted stock and shares under the long-term incentive plans have an exercise price of zero.

The reconciliation of basic net income per common share to diluted net income per common share is shown in the following table for the three-month periods ended March 31, 2012 and 2011:
