Preferred Stock [Abstract]
Preferred Stock	8. Preferred Stock During May 1998, as part of a private placement, the Company issued 4,000 shares of Convertible Preferred Stock for proceeds of $4.0 million. The proceeds of the offering are included in the proceeds to the May 1998 financing described in Note 7, above. During January 1999, the Company issued 346,127 shares of common stock in connection with the conversion of the Series A Convertible Preferred Stock and additional shares relating to the Adjustable Common Stock. The Adjustable Common Stock was issued during the private placement of May 1998 and was subject to adjustment based on the future average stock price of the Company's common stock as described in Note 7. Upon conversion, all outstanding shares of Preferred stock and Adjustable Common stock were eliminated. In November 1999, the Company adopted a Shareholders Rights Plan in which Preferred Stock purchase rights ("Rights") were distributed as a dividend at the rate of one Right for each share of common stock held as of the close of business on November 29, 1999. Each right entitled stockholders to buy, upon certain events, one one-hundredth of a share of a new Series B junior participating preferred stock of the Company at an exercise price of $100.00. The Rights are designed to guard against partial tender offers and other abusive tactics that might be used in an attempt to gain control of the Company or to deprive stockholders of their interest in the long-term value of the Company. The Rights were exercisable only if a person or group acquires 15% or more of the Company's common stock or announces a tender offer of which the consummation would result in ownership by a person or group of 15% or more of the Company's common stock. The Rights were redeemable for one cent per Right at the option of the Board of Directors prior to this event occurring. The Rights expired on November 14, 2009. Effective October 19, 2009, the Company executed an Amended and Restated Rights Agreement (the "Rights Agreement") between the Company and American Stock Transfer and Trust Company, LLC, as Rights Agent, amending and restating the Rights Agreement dated as of November 15, 1999 (the "Original Rights Agreement"). The purposes of this amendment of the Original Agreement include, among other things: to extend the expiration date of the Preferred Stock purchase rights issued from November 14, 2009 to November 14, 2019; to change how many new shares of common stock the Rights holders can purchase at a price of $100 per Right ( the "Purchase Right") after the 15% threshold is crossed from two times the number of the Company's common stock that the Purchase Price is worth to five times the number of Company's common stock that the Purchase Price is worth; to decrease the redemption price for Company-initiated redemption of the Rights from $0.01 to $0.0001. On July 28, 2011, we sold an aggregate of 2,000,000 shares of our Series A Preferred Stock (the "Redeemable Preferred Shares") to Amun, LLC, a Delaware limited liability company (the "Investor") pursuant to the terms of a Stock Purchase Agreement (the "Purchase Agreement") and related Stockholders Agreement (the "Stockholders Agreement"). The Redeemable Preferred Shares represent approximately a 28% of the economic interest in the Company and also entitle the Investor to a number of votes equal to 38.28% of the total number of votes entitled to be cast by holders of all shares of the Company's capital stock (including the Common Stock and Series A Preferred Stock) voting together as single class. Under the terms of these and other related agreements between the Company and the Investor, the Investor placed $2.825 million in cash into an escrow account, which amount is available under certain circumstances to pay certain Company related expenses and to fund the Company's working capital needs. Amounts received are included as restricted cash as of December 31, 2011. The Stockholder Agreement provides that the Investor will have the right to "put" the Redeemable Preferred Shares acquired pursuant to the Purchase Agreement back to the Company in return for the remaining cash held in escrow at the time of the put, upon the occurrence of certain events.
