(13) Earnings Per Share

The computation of basic earnings per share (EPS) is based on the weighted average number of the Company’s common shares outstanding. The computation of diluted EPS is based on the weighted average number of the Company’s common shares outstanding and potential dilutive common shares during the period as determined by using the treasury stock method.

The following are computations of basic and diluted earnings per share (in thousands, except for per share amounts):

In the table above, potentially dilutive shares outstanding include the dilutive effect of unvested restricted stock awards. Shares under the Employee Stock Purchase Plan (“ESPP”) which commenced in 2024 are issued on the last day of the offering period and therefore are included in the weighted average shares outstanding when issued.

Potentially dilutive shares whose effect would have been antidilutive have been excluded from the computation of diluted earnings per share. The Company included all outstanding performance awards and restricted stock awards in the calculation of diluted earnings per share except as shown in the table below (in thousands):
