Income Per Common Share [Abstract]

Income Per Common Share

(9) Income per Common Share

Basic net income per share was computed by dividing net income available to common stockholders for the period by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share was computed by dividing net income available to common stockholders for the period by the weighted average number of shares of common stock that would have been outstanding assuming dilution from stock-based compensation awards during the period.

The Company's time vested restricted stock, which is a participating security, is included in the computation of earnings per share pursuant to the two-class method. Undistributed net income allocated to unvested restricted stock was not material for the three month periods ended December 31, 2011 and 2010. The following table sets forth the computation of net income per share:
