Stockholders Equity Note [Abstract]
Stockholder's Equity	NOTE 10 – STOCKHOLDERS’ EQUITY We have never declared or paid cash dividends on our Common Stock. Our U.S. Credit Facility permits us to pay dividends up to $3.0 million per fiscal year to its stockholders so long as we have not defaulted at the time of such dividend and no default would result from declaring or paying such dividend. The payment of dividends is within the discretion of our Board of Directors. See Note 7 for additional information regarding our credit agreements. During November 2015 the Company’s board of directors authorized a share repurchase plan to repurchase up to an aggregate of $100 million of the Company’s outstanding common stock, $0.66 2/3 par value per share.
