Synthetic Genomics Asset Acquisition [Abstract]
Synthetic Genomics Asset Acquisition	13. Synthetic Genomics Asset Acquisition On February 28, 2018, C3J completed an acquisition of certain synthetic phage assets (the “synthetic phage assets”) from “SGI” for consideration consisting of $8.0 million in cash and $27.0 million in equity. The cash payments consisted of: $1.0 million paid at closing on February 28, 2018, $1.0 million at one year from closing, $1.0 million at two years from closing, and $5.0 million at three years from closing (the payments due on the one, two, three year anniversary are collectively the “time-based payment obligation”). The equity payment (the “equity payment” and, together with the time-based payment obligation, the “deferred purchase price arrangement”) is due upon the earlier of the initial public offering of shares of C3J’s common stock pursuant to an effective registration statement under the Securities Act of 1933, as amended, the sale of all or substantially all of C3J’s assets to a third party, or a consolidation or merger into a third party. On December 20, 2018, in contemplation of the Merger (see Note 5), the deferred purchase price arrangement was amended. Under the amended agreement, the purchase consideration consisted of (i) closing consideration of $1.0 million paid on February 28, 2018, (ii) cash payments of $1.0 million on January 31, 2019, $1.0 million on January 31, 2020, and $2.0 million on January 31, 2021, (iii) an issuance of that number of shares of C3J’s common stock equal to ten percent of C3J’s fully-diluted capitalization, excluding options and restricted stock awards, immediately prior to the closing of the Merger, and (iv) potential milestone payments of up to $39.5 million related to the development and relevant regulatory approval of products utilizing bacteriophage from the synthetic phage assets acquired from SGI (the “milestone payment obligation”). The equity payment was determined to be a derivative liability in accordance with ASC 815, Derivatives and Hedging and was initially recorded at its fair value of $2.8 million. Throughout 2018 and until May 9, 2019, the derivative liability was adjusted to its fair value based upon a payment probability assessment and marked-to-market at the end of each period (see Note 4). Following the December 20, 2018 amendment to the deferred purchase price arrangement, the Company considered the probability of the reduction to the share issuance consideration in estimating the fair value of the derivative liability. For the six months ended June 30, 2019, the Company recognized $0.5 million of interest expense related to the time-based payment obligations. In connection with the Merger, the Company converted its equity payment obligation to SGI by issuing 516,976 shares of C3J’s common stock in connection with the amended agreement, after considering the Merger exchange ratio and reverse stock split in the manner described above. Through May 9, 2019, the derivative liability associated with the equity payment was updated for its estimated market value. Upon closing of the Merger, the fair value of the derivative liability was estimated at zero as the equity payment is no longer required to be made in the future. The change in fair value is reflected in other income.
