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, 2012 and 2011.
 
In August 2011, our Board of Directors authorized the purchase of up to $5 million of our common stock under a stock repurchase program.  Under this program, during the years ended December 31, 2012 and 2011, we repurchased 68,250 shares and 322,250 shares, respectively, of our common stock at a total cost of $0.9 million and $4.1 million, respectively.  No stock repurchases remain available under the 2011 program as the entire $5 million was utilized.
 
In May 2012, our Board of Directors authorized the purchase of up to an additional $5 million of our common stock under a stock repurchase program.  Under this program, during the year ended December 31, 2012 we repurchased 312,527 shares of our common stock at a total cost of $4.1 million, leaving approximately $0.9 million available for future stock repurchases under the program.  Restrictive covenants under our revolving credit facility prohibited any such further purchases in 2012.
