Convertible Preferred Stock And Stock Warrants [Abstract]
Convertible Preferred Stock And Stock Warrants	Note 11 — Convertible Preferred Stock and Stock Warrants On August 12, 2009, the Company sold 16,000 units (the "Units"), consisting of preferred stock and warrants for $1,000 per Unit. Each Unit consisted of one share of Series A of cumulative convertible preferred stock ("Convertible Preferred Stock"), detachable warrants to purchase up to 155 shares of the Company's common stock at an exercise price of $2.31 per share ("Exercisable Warrants") and detachable Contingent Warrants to purchase up to 500 shares of the Company's common stock at an exercise price of $2.45 per share ("Contingent Warrants"). The gross proceeds from the issuance of the Units were allocated, at the transaction date, based upon the preferred stock and warrants relative fair values. At the date of the transaction, the Company recorded approximately 68% of the proceeds or $10.8 million (net of the discount recognized from the allocation of proceeds to the detachable warrants) as preferred stock in stockholders' equity. The fair value of the detachable warrants was assessed at $5.2 million and recorded as a warrant liability. The Company determined the conversion option embedded within the preferred stock had intrinsic value and was beneficial to the holders of the preferred stock. Accordingly, $5.2 million was recorded as a beneficial conversion discount with an offset to additional paid-in capital at the date of the transaction. The preferred stock conversion period was estimated to be 36 months based on an evaluation of the conversion options. *Preferred Stock* Each share of Convertible Preferred Stock was convertible at any time, at the holder's option, into 434.782 shares of the Company's common stock. Dividends accrued at a rate of 15% of the liquidation preference per year and accumulated, if not paid quarterly. Subsequent to February 11, 2010, the Company had the ability to automatically convert the preferred shares into common shares if the closing price of the common stock met certain price criteria. In the event any Convertible Preferred Stock was automatically converted, the Company was also obligated to pay an amount, in cash or common stock, equal to eight quarterly dividend payments less any dividends previously paid. During January and February 2011, the Company paid dividends on the outstanding shares of Convertible Preferred Stock in shares of the Company's common stock. The payment, at an annual rate of 15% of the liquidation preference, had a value of $300 per share. In February 2011, the Company exercised its contractual right to mandatorily convert all outstanding shares of Convertible Preferred Stock into shares of common stock at the prevailing conversion rate of 434.782 shares of common stock for each share of preferred stock. *Stock Warrants* Exercisable Warrants were exercisable upon issuance and expire August 12, 2014, if not exercised. Contingent Warrants became exercisable on November 9, 2009, and expire November 9, 2014, if not exercised. The warrants contain anti-dilution price protection in the event the Company issues shares of common stock or securities exercisable for, or convertible into, common stock at a price per share less than the warrants' exercise price. Due to the anti-dilution price adjustment provision in the warrant agreements, the warrants are considered a liability and are recorded at fair value. The warrant liability is adjusted to fair value at the end of each reporting period through the statement of operations over the life of the warrants. In accordance with contractual anti-dilution price adjustment provisions, the warrants were re-priced as a result of the payment of a portion of the initial and deferred commitment fees related to the Company's Term Loan with common stock on March 31, 2010 and September 30, 2010. At March 31, 2012, all outstanding warrants have an exercise price of $1.21 per share. During the three months ended March 31, 2012, no warrants were exercised to purchase shares of the Company's common stock. At March 31, 2012, Exercisable and Contingent Warrants to purchase up to 1,892,600 shares of common stock remain outstanding. The Company uses the Black-Scholes option-pricing model to estimate the fair value of the warrant liability at the end of each reporting period. At March 31, 2012, inputs into the fair value calculation included the actual remaining term of the warrants, a volatility rate of 58.1%, a risk-free rate of return of 0.4%, and an assumed dividend rate of zero.
