Restatement of Financial Statements [Text Block] | Note 2. Restatement of Consolidated Financial Statements On November 4, 2015, the Audit Committee of the Company’s Board of Directors (the “Audit Committee”), in connection with an internal review initiated by Company management, concluded that, because of a misapplication of the accounting guidance related to certain of the Company’s warrants, the Company’s previously issued consolidated financial statements for all periods beginning with the quarterly period ended September 30, 2010 through June 30, 2015 (collectively, the “Affected Periods”) should no longer be relied upon. As such, the Company is restating in this Annual Report its financial statements for the following periods: (i) the years ended December 31, 2014 and December 31, 2013, and (ii) all quarterly periods of 2014 and 2013, and (iii) the quarterly periods ended March 31, 2015 and June 30, 2015. However, these restatements result in non-cash, non-operating financial statement corrections and will have no impact on the Company’s current or previously reported cash position, operating expenses or total operating, investing or financing cash flows, or net operating loss carryforward. The Company’s December 31, 2012 opening balances were adjusted to reflect the cumulative impact of these restatements as a decrease in additional paid-in capital of approximately $4.9 million and a decrease in accumulated deficit of approximately $4.4 million, for a total change to stockholders’ equity of approximately $0.5 million. The warrants at issue (collectively, the “Warrants”) consist of the following outstanding as of December 31, 2014 and December 31, 2013: December 31, 2014 2013 Issued to Investors on July 28,2010, entitling the holders to purchase 1,034,996 1,034,996 1,034,996 Issued to Investors on October 25, 2013, entitling the holders to purchase 1,250,000 1,117,178 1,250,000 Issued to Investors on November 17, 2014, entitling the holders to purchase 2,734,590 2,734,590 - Total 4,886,764 2,284,996 The Warrants were classified as equity on the Company’s consolidated balance sheets. The corresponding Consolidated Statements of Operations did not include the non-cash changes in the estimated fair value of such Warrants. Those Warrants, however, contain a cash settlement feature regarding fundamental transactions that allowed those Warrant holders to have a different settlement option than the Company’s stockholders upon certain fundamental transactions, including a change of control of the Company, thereby precluding equity treatment for the Warrants. Based on Accounting Standards Codification 815, Derivatives and Hedging The cumulative effect of these adjustments on our financial statements is a 7.7% decrease in the accumulated deficit in the amount of approximately $5.8 million as of December 31, 2014. The restatement had no impact on net cash flows from operating, investing or financing activities as the adjustments resulting from the non-cash change in the fair value of the warrant liability for each period and the statements of operations only impacted net loss from operations.
