Subsequent Event [Line Items]
Subsequent Events [Text Block]	Subsequent Events During the second quarter of 2014, certain investors elected to convert a total of $22.0 million principal of the $38.0 million in aggregate principal of the 8.0% Senior Unsecured Convertible Notes. Under the terms of the Notes they are convertible into shares of the Company's common stock at a conversion rate of 645.1613 shares of common stock per $1,000 principal amount of convertible notes, equivalent to a conversion price of approximately $1.55 per share of common stock plus a "make-whole" payment equal to the lesser of three years of interest payments or interest payments from the date of conversion through maturity of the convertible notes.  As a result of these conversions, the Company retired $22.0 million of outstanding principal and issued 17.5 million shares of common stock.  The remaining principal balance of the 8.0% Senior Unsecured Convertible Notes is $1.0 million.
