Dispositions [Abstract] |
Dispositions | 7. Dispositions On November 4, 2015, XOMA and Ology Bioservices, Inc. (“Ology Bioservices”) entered into an asset purchase agreement under which Ology Bioservices agreed to acquire XOMA’s biodefense business and related assets (including certain contracts with the U.S. government), and to assume certain liabilities of XOMA. As part of the 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. 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. In February 2017, the Company executed an Amendment and Restatement to both the asset purchase agreement and Ology Bioservices License Agreement. Based on the payment terms pursuant to the amended Ology Bioservices License Agreement, the Company was entitled to receive cash consideration in aggregate of $4.6 million, all of which was received as of December 31, 2018. No further payments remain under the agreement, but the Company is still eligible to receive royalties in the future. The Company received $1.0 million during the three months ended March 31, 2018, which was recognized as other income, net in the condensed consolidated statement of operations and comprehensive loss.
