Note (5) - Earnings Per Share: The Company computes earnings per share using the two-class method. The two-class method of computing earnings per share is an earnings allocation formula that determines earnings per share for common stock and any participating securities according to dividends declared (whether paid or unpaid) and participation rights in undistributed earnings. Shares of the Company’s common stock subject to unvested restricted stock awards and restricted stock units are considered participating securities because they contain a non-forfeitable right to cash dividends (in the case of restricted stock awards) or dividend equivalents (in the case of restricted stock units) paid prior to vesting or forfeiture, if any, irrespective of whether the awards or units ultimately vest. Basic and diluted earnings per share for the nine and three months ended March 31, 2021 and 2020 are computed as follows (in thousands, except per share data):

At March 31, 2021 and 2020, other than 1,202,275 shares and 1,068,753 shares, respectively, of common stock subject to unvested restricted stock awards or restricted stock units, there were no potentially dilutive securities outstanding.
