Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share We had 33,070 shares of nonvested restricted stock at September 30, 2022 and 26,618 shares of nonvested restricted stock at September 30, 2021 that were excluded from the calculation of diluted earnings per share, as their effect on earnings per share would be anti-dilutive. The nonvested restricted stock is considered a participating security since the restricted stock contains nonforfeitable rights to dividends. As such, we use the two-class method to compute basic and diluted earnings per share for all periods presented since this method yields the most dilutive result. The following table illustrates the earnings allocation method utilized in the calculation of basic and diluted earnings per share.
