13.	Stockholders’ Equity

We have authority to issue 500,000 shares of preferred stock, $20 par value, and our Board of Directors is vested with the authority to establish and designate any series of preferred, to fix the number of shares therein and the variations in relative rights as between each series. In December 1995, our Board of Directors established a new series of preferred shares designated as Series A Participating Preferred Stock. The number of shares constituting the Series A Preferred Stock is 30,000. The Series A Preferred Stock is designed to participate in dividends, ranks senior to our common stock as to dividends and liquidation rights and has voting rights. Each share of the Series A Preferred Stock shall entitle the holder to one thousand votes on all matters submitted to a vote of the stockholders of the Company. No such shares were outstanding at December 31, 2018 and 2017.
