Stockholders' Equity Note Disclosure [Text Block] | NOTE 16 – 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. Under this program the Company reacquired and retired - 0 -, 45,100 and - 0 - shares of its common stock in the years ended December 31, 2017, 2016 and 2015, respectively. At December 31, 2017, the Company had 216,575 shares remaining on 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. There is no expiration date or other restriction governing the period over which the Company can make its share repurchases under the program.
