Earnings Per Share [Text Block] | NOTE 4 - EARNINGS PER SHARE The Company provides dual presentation of basic and diluted earnings per share.

Diluted earnings per share adds the dilutive effects of stock options and restricted stock to average shares outstanding. The following table sets forth the composition of the weighted-average common shares (denominator) used in the basic and diluted earnings-per-share computation.

Options to purchase 13,600 shares of common stock, at prices ranging from $17.55 to $ 23.00 , were outstanding during the three and nine months ended September 30, 2018. Also outstanding were 20,425 shares of restricted stock. None of the outstanding options or restricted stock were anti-dilutive. When shares recognized as equity are repurchased, the amount of the consideration paid, which includes directly attributable costs, is recognized as a deduction from equity. Repurchased shares are classified as treasury shares and are presented in the treasury share reserve. When treasury shares are sold or reissued subsequently, the amount received is recognized as an increase in equity and the resulting surplus or deficit on the transaction is presented within the share premium. The reserve for the Company’s treasury shares comprises the cost of the Company’s shares held by the Company. As of September 30, 2019, the Company held 435,581 of the Company’s shares, which is an increase of 31,669 for the quarter, and 49,416 for the nine months ended September 30, 2019, from the 386,165 shares held as of December 31, 2018.
