Dispositions [Abstract] |
Dispositions | 6. Dispositions Biodefense Assets On November 4, 2015, XOMA and Nanotherapeutics Inc. (“Nanotherapeutics”) entered into an asset purchase agreement (the “Nanotherapeutics Purchase Agreement”), pursuant to which Nanotherapeutics agreed, subject to the terms and conditions set forth in the Nanotherapeutics Purchase Agreement, to acquire XOMA’s biodefense business and related assets (including, subject to regulatory approval, certain contracts with the U.S. government), and to assume certain liabilities of XOMA (the “Transaction”). As part of the Transaction, the parties will, subject to the terms and conditions of the asset purchase agreement and the satisfaction of certain conditions, enter into an intellectual property license agreement (the “License Agreement”), pursuant to which XOMA agreed to license to Nanotherapeutics, subject to the terms and conditions set forth in the License Agreement, certain intellectual property rights related to the purchased assets. Under the License Agreement, the Company is eligible to receive up to $4.5 million of cash payments upon Nanotherapeutics’ execution of a contract with the Defense Threat and Reduction Agency. In addition, the Company is eligible to receive 15% royalties on net sales of products. Manufacturing Facility On November 5, 2015, XOMA and Agenus West, LLC, a wholly-owned subsidiary of Agenus Inc. (“Agenus”), entered into an asset purchase agreement (the “Agenus Purchase Agreement”), pursuant to which Agenus agreed, subject to the terms and conditions set forth in the Agenus Purchase Agreement, 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. The remaining $0.5 million of Agenus common stock will only be received upon the Company’s satisfaction of certain organizational matters, which XOMA may or may not be able 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 has determined that such assets qualify 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 loss for the year ended December 31, 2015.
