Dispositions | 6. Dispositions Biodefense Assets On November 4, 2015, the Company and Ology Bioservices entered into an asset purchase agreement under which Ology Bioservices agreed to acquire XOMA’s biodefense business and related assets (including, subject to government approval, certain contracts with the U.S. government), and to assume certain liabilities of XOMA. As part of that transaction, the parties entered into an intellectual property license agreement (the “Ology Bioservices License Agreement”), under which XOMA agreed to license to Ology Bioservices certain intellectual property rights related to the purchased assets. Under the Ology Bioservices License Agreement, the Company was eligible to receive contingent consideration up to a maximum of $4.5 million in cash and 23,008 shares of common stock of Ology Bioservices, based upon Ology Bioservices achieving certain specified future operational objectives. In addition, the Company is eligible to receive 15% royalties on net sales of any future Ology Bioservices products covered by or involving the related patents or know-how. On March 17, 2016, the Company effected a novation of its NIAID 4 contract to Ology Bioservices. On March 23, 2016, the Company completed the transfer of NIAID 4 and certain related third-party service contracts and materials, and the grant of exclusive and non-exclusive licenses for certain of its patents and general know-how to Ology Bioservices. The Company believes that NIAID 4 and certain related third-party service contracts and materials related to the biodefense program transferred to Ology Bioservices include a sufficient number of key inputs and processes necessary to generate output from a market participant’s perspective. Accordingly, the Company has determined that such assets qualified as a business. The transaction had no impact on the Company’s consolidated financial statements as of, and for the year ended, December 31, 2016. In February 2017, the Company executed an Amendment and Restatement to both the asset purchase agreement and Ology Bioservices License Agreement primarily to (i) remove Ology Bioservices’ obligation to issue 23,008 shares to the Company of its common stock under the asset purchase agreement, and (ii) revise the payment schedule related to the timing of the $4.5 million cash payments due to the Company under the Ology Bioservices License Agreement. Of the $4.5 million, $3.0 million was contingent upon Ology Bioservices achieving certain specified future operating objectives, which Ology Bioservices achieved in 2017. Based on the payment terms pursuant to the amended Ology Bioservices License Agreement, the Company is entitled to receive an aggregate of $4.6 million. The Company received $2.2 million during the year ended December 31, 2017, which was recognized as other income in the consolidated statement of comprehensive income (loss). As the amended Ology Bioservices License Agreement involves extended payment terms, the remaining $2.4 million, of which $1.7 million is due in monthly installments through July 2018 and $0.7 million is due in quarterly installments through September 2018, will be recognized as other income as the payments are received. Manufacturing Facility On November 5, 2015, the Company and Agenus West, LLC, a wholly-owned subsidiary of Agenus Inc. (“Agenus”), entered into an asset purchase agreement under which Agenus agreed to acquire XOMA’s manufacturing facility in Berkeley, California, together with certain related assets, including certain intellectual property related to the purchased assets under an intellectual property license agreement, and to assume certain liabilities of XOMA, in consideration for the payment to XOMA of up to $5.0 million in cash and the issuance to XOMA of shares of Agenus’ common stock having an aggregate value of up to $1.0 million. On December 31, 2015, XOMA completed the sale of the manufacturing facility, including certain related equipment and furniture, and the grant of non-exclusive licenses for certain of its patents and general know-how to Agenus for cash consideration of $4.7 million, net of the assumed liabilities of $0.3 million at closing. In addition to the cash consideration, XOMA received 109,211 shares of common stock of Agenus with an aggregate value of $0.5 million, which the Company subsequently sold in August 2016. The remaining $0.5 million of Agenus common stock will only be received upon the Company’s satisfaction of certain organizational matters, which XOMA is unlikely to satisfy. Agenus also paid $0.2 million to the Company as consideration for the employees who would not have otherwise been retained by the Company had the manufacturing facility closed on October 31, 2015. At closing, the carrying value of the assets sold was $2.2 million. The Company believes that the assets related to the manufacturing facility and certain other assets sold to Agenus include all key inputs and processes necessary to generate output from a market participant’s perspective. Accordingly, the Company determined that such assets qualified as a business. The Company recorded the gain on the sale of a business of $3.5 million in the other income (expense), net line of the consolidated statement of comprehensive income (loss) for the year ended December 31, 2015.
