Stockholders' Equity Note Disclosure [Text Block] | NOTE 15 – Stock Repurchase Plan: On August 1, 2008, the Company’s Board of Directors approved an increase to the outstanding authorization under its common stock repurchase program to allow for the repurchase of 1,000,000 additional shares of the Company’s outstanding shares of common stock. During the year ended December 31, 2018, the Company reacquired and retired the remaining 58,216 shares of its common stock under this program. On May 2, 2019, the Company’s Board of Directors approved a stock repurchase program of up to 750,000 shares of Company’s outstanding common stock. There is no expiration date or other restriction governing the period over which the Company can make share repurchases under the program. All purchases under this program will be open market transactions. Under this program, the Company reacquired and retired 43,458 and 49,091 shares of its common stock during the years ended December 31, 2020 and 2019, respectively. At December 31, 2020, the Company had 657,451 shares remaining under its common stock repurchase program. Shares purchased under the common stock repurchase program are constructively retired and returned to unissued status. The Company considers several factors in determining when to make share repurchases, including among other things, the cost of equity, the after-tax cost of borrowing, the debt to total capitalization targets and the expected future cash needs.
