Income Per Common Share [Abstract]

Income Per Common Share

6.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.

Unvested stock-based compensation awards that contain non-forfeitable rights to dividends are treated as participating securities and included in the computation of earnings per share pursuant to the two-class method. The Company’s time vested restricted stock is a participating security. The following table sets forth the computation of net income per share for the years ended September 30:
