Debt Disclosure [Abstract]
Debt Disclosure [Text Block]	Debt Related Party Convertible Note In December 2014, in connection with the acquisition of Overland, the existing debt of Overland and the remaining debt of the Company were amended and restated into a $19.5 million convertible note held by FBC Holdings. In April 2016, the Company modified its convertible note with FBC Holdings, pursuant to which the holder made an additional advance and principal amount under the convertible note amount was increased to $24.5 million. The convertible note bears interest at an 8.0% simple annual interest rate, payable semi-annually. The obligations under the convertible note are secured by substantially all assets of the Company. At March 31, 2018, the Company had $23.8 million, net of unamortized debt costs of $0.7 million, outstanding on the convertible note. The Company has the option to pay accrued and outstanding interest either entirely in cash or common shares. If the Company choses to pay the interest in common shares, the calculation is based upon the number of common shares that may be issued as payment of interest on the convertible note and will be determined by dividing the amount of interest due by the current market price as defined in the convertible note agreement. For the three months ended March 31, 2018 and 2017, the Company issued 344,959 and zero common shares, respectively, for the settlement of accrued interest expense. In March 2018, the Company and FBC Holdings entered into an amendment to the convertible note, under which the maturity date was extended from March 31, 2018 to May 31, 2018. The amendment also altered the schedule for interest payments under the FBC Debenture by providing for future accrued interest to be paid twice monthly rather than semi-annually. In partial consideration for the extension, the Company agreed to pay to FBC Holdings a fee, payable in cash or common shares of the Company at the Company’s option, of $735,000, payable in full by May 16, 2018. In April 2018, the Company issued in the aggregate 950,579 common shares to FBC Holdings for payment of accrued interest and partial payment of fees related to the March 2018 amendment to the convertible note. In November 2015, the convertible note’s conversion price was adjusted to $75.00 per share. At the option of the Company, the convertible note is convertible into common shares at the conversion price at any time that the weighted average trading price for the common shares exceeds 150% of the conversion price (i.e. exceeds $112.50 per share), for ten consecutive trading days on its principal stock exchange that the common shares trade. The convertible note contains customary covenants, including covenants that limit or restrict the Company’s ability to incur liens, incur indebtedness, or make certain restricted payments. Upon the occurrence of an event of default under the convertible note, the Holder may declare all amounts outstanding to be immediately due and payable. The convertible note specifies a number of events of default (some of which are subject to applicable grace or cure periods), including, among other things, non-payment defaults, covenant defaults, cross-defaults to other materials indebtedness, bankruptcy and insolvency defaults, and material judgment defaults. As of March 31, 2018, the Company was in compliance with all covenants of the convertible note. For the three months ended March 31, 2018 and 2017, interest expense, including amortization of debt costs, on the convertible note was $0.6 million and $0.5 million, respectively.
