Note, Warrant And Common Stock Purchase Agreement [Abstract] |
Note, Warrant And Common Stock Purchase Agreement [Text Block] | Note 12 – Note, Warrant, & Common Stock Purchase Agreement with related parties In October 2014, the Company entered into a Note and Warrant Purchase Agreement (the “Note and Warrant Purchase Agreement”) with four members of the Company’s Board of Directors to issue an aggregate of $1,000,000 in principal amount of promissory notes (the “Notes”) and warrants (the “Warrants”) to purchase an aggregate of 200,000 shares of the common stock, no par value (the “Common Stock”), of the Company (the “Notes and Warrants Offering”). The Notes incurred interest at a rate of 15.0% per annum and had a maturity date of October 22, 2017. Interest only payments were due monthly with the option to prepay the outstanding principal on or after December 31, 2015. The Warrants expire three years after their initial issuance date and may be exercised for a purchase price equal to $2.20 per share of Common Stock, the closing price per share of the Company’s Common Stock on the New York Stock Exchange MKT on the date preceding the date of the Note and Warrant Purchase Agreement. During the year ended December 31, 2016, 100,000 of the warrants were exercised and 100,000 remain outstanding as of the year ended. During the year ended December 31, 2016, the Company paid down the Notes. Based on the guidance provided in accordance with ASC 405 Extinguishment of Liabilities (“ASC 405”) and ASC 470 Debt Modifications and Extinguishments (“ASC 470”), the pay-down of the Notes is considered an extinguishment of debt and, as such, the difference between the net carrying amount of the Notes and the costs of extinguishment was recognized as a loss on the Company’s condensed consolidated statements of operations. During the year ended December 31, 2016, the Company recorded a loss on early extinguishment of debt of $108,000. The Notes were issued with common stock warrants with an estimated fair value of $145,000. The unamortized balance of the discount on the Notes, of $80,000, and deferred fees incurred from the issuance of the Note of approximately $28,000, were recorded as a loss on early extinguishment. Concurrently with the Note and Warrant Purchase Agreement, the Company entered into a common stock purchase agreement (the “Common Stock Purchase Agreement”) with one member of the Company’s Board of Directors to sell, in a private offering, 100,000 shares of the Company’s Common Stock (the “Private Placement Shares”), for gross proceeds of $220,000 (the “Common Stock Offering” and, together with the Notes and Warrants Offering, the “Private Offering”). The Common Stock Purchase Agreement contains terms and conditions that are customary for a transaction of this type. The Company received gross proceeds of $1,220,000 in the Private Offering, which were used, together with cash on hand, to make two payments of $1,000,000 each to Mevion as deposits pursuant to the terms of purchase commitments with Mevion.
