Earnings Per Share [Text Block] | Note 8 – Earnings per Share Basic net income per share is computed based on the weighted average number of common shares outstanding for each period presented. Diluted net income per share reflects the potential dilution that would have occurred if securities to issue common stock were exercised, converted, or resulted in the issuance of common stock that would have then shared in our earnings. The following table summarizes the earnings and the weighted average number of common shares used in the calculation of basic and diluted earnings per share (in thousands, except for share and per share amounts):

For the three and nine months ended September 30, 2025, 6,450 stock options were excluded from the calculation of diluted weighted average shares of common stock outstanding because the inclusion of these securities would have an anti-dilutive impact. For the three and nine months ended September 30 2024, we did not exclude any stock options from the calculation of diluted weighted average shares of common stock outstanding because the inclusion of these securities would have an anti-dilutive effect.
