Equity [Abstract]
Stockholders' Deficiency	Stockholders’ Deficiency On December 31, 2017, the Company’s authorized share capital consisted of 620,000,000 shares, of which 600,000,000 are designated common shares and 20,000,000 are designated preferred shares. The Company’s Board of Directors is authorized to issue preferred shares in series with rights, privileges and qualifications of each series determined by the Board. As of December 31, 2017 and 2016, no preferred shares were outstanding or issued. Rights Offering On November 16, 2016, the Company completed a rights offering (the “Rights Offering”), pursuant to which it raised approximately $35.3 million in gross proceeds through the sale of 23,523,195 shares of its common stock. The Rights Offering was made pursuant to a registration statement on Form S-1 and declared effective by the SEC on October 21, 2016. As part of the Rights Offering, each stockholder of the Company received a subscription right for each share of common stock owned as of the record date of October 12, 2016. Each subscription right entitled its holder to invest $0.65 towards the purchase of shares of the Company's common stock at a subscription price equal to the lower of $1.50 or 85% of the volume weighted average price of Company shares during market hours on the expiration date of the Rights Offering. The Rights Offering expired on November 8, 2016. Through basic subscriptions and oversubscriptions, the Rights Offering was fully subscribed. The subscription price was set at $1.50. The Company used the net proceeds of the Rights Offering, together with proceeds from the Term Loan and cash on hand, to fully satisfy PharmAthene's claim under the Plan. Rights Offering-Backstop Agreement On October 13, 2016, in connection with the Rights Offering as discussed above, the Company entered into an investment agreement or “backstop agreement”, with an affiliate of MacAndrews & Forbes Incorporated (“M&F”) (see Note 13), and certain other backstop parties (the “Backstop Parties”). Under the terms of the backstop agreement, the Backstop Parties agreed to purchase, pursuant to a separate private placement, a number of shares of common stock equal to the numbers of shares that were not subscribed for in the Rights Offering. Because the Rights Offering was fully subscribed, the Backstop Parties were not required to draw on such commitment. The Company issued 708,530 shares to Backstop Parties, of which approximately 565,000 shares were received by M&F, in payment of the five percent backstop fee ($1,764,240) payable to the Backstop Parties in connection with the backstop agreement. The fair value of the shares issued in satisfaction of the backstop fee was expensed in the income statement in the fourth quarter of 2016. There are no remaining payment obligations to the Backstop Parties under the backstop agreement.
