Stockholders' Equity Note [Abstract]
Stockholders' Equity	8. Stockholders’ Equity Preferred Stock As of June 30, 2017, there were 335,273 shares of the Company’s 6% Convertible Exchangeable Preferred Stock (“Preferred Stock”) issued and outstanding at an issue price of $10.00 per share. Dividends on the Preferred Stock are cumulative from the date of original issuance at the annual rate of 6% of the liquidation preference of the Preferred Stock, payable quarterly on the first day of February, May, August and November, commencing February 1, 2005. Any dividends must be declared by the Company’s Board and must come from funds that are legally available for dividend payments. The Preferred Stock has a liquidation preference of $10.00 per share, plus accrued and unpaid dividends. The Company may automatically convert the Preferred Stock into common stock if the closing price of the Company’s common stock has exceeded $2,961, which is 150% of the conversion price of the Preferred Stock, for at least 20 trading days during any 30-day trading period, ending within five trading days prior to notice of automatic conversion. The Preferred Stock has no maturity date and no voting rights prior to conversion into common stock, except under limited circumstances. The Company may, at its option, redeem the Preferred Stock in whole or in part, out of funds legally available at the redemption price of $10.00 per share. The Preferred Stock is exchangeable, in whole but not in part, at the option of the Company on any dividend payment date beginning on November 1, 2005 (the “Exchange Date”) for the Company’s 6% Convertible Subordinated Debentures (“Debentures”) at the rate of $10.00 principal amount of Debentures for each share of Preferred Stock. The Debentures, if issued, will mature 25 years after the Exchange Date and have terms substantially similar to those of the Preferred Stock. No such exchanges have taken place to date. On May 30, 2017, the Board declared a quarterly cash dividend in the amount of $0.15 per share on the Company’s 6% Convertible Exchangeable Preferred Stock (“Preferred Stock”). The cash dividend was paid on August 1, 2017 to the holders of record of the Preferred Stock as of the close of business on July 14, 2017. Common Stock June 2016 At Market Issuance On June 23, 2016, the Company entered into a sales agreement with FBR (the “FBR Sales Agreement”), under which the Company may issue and sell shares of its common stock, from time to time through FBR, acting as its sales agent. Under the FBR Sales Agreement, FBR may sell the shares of common stock by any method that is deemed to be an “at the market offering”. The Company will pay FBR a commission of 3.0% of the gross sales price per share sold. The Company is not obligated to make any sales of common stock under the FBR Sales Agreement. In the six months ended June 30, 2017, the Company sold 183,118 shares of common stock under the sales agreement for net proceeds of approximately $1.1 million. This now concludes the Company’s existing sales agreement with FBR.
