Note 7 – Earnings Per Share

The Company follows FASB's guidance regarding the calculation of earnings per share (“EPS”) for nonvested stock awards with rights to non-forfeitable dividends. The guidance requires nonvested stock awards with rights to non-forfeitable dividends to be included as part of the basic weighted average share calculation under the two-class method.

The following table summarizes EPScalculations:
