Asset Retirement Obligation Disclosure [Abstract] |
Sale of Non-Financial Assets | Asset Sale In September 2020, the Company completed the sale of its XERMELO product and related assets (the “XERMELO sale”) to TerSera pursuant to an Asset Purchase and Sale Agreement entered into in July 2020. The final consideration paid by TerSera was $160.0 million and the net gain recognized in connection with the XERMELO sale was $132.6 million. The gain is reflected on the consolidated statement of comprehensive income (loss) for the year ended December 31, 2020. The Company remains eligible to receive development, regulatory and sales milestone payments of up to an aggregate of $65.0 million for the development and commercialization of XERMELO in patients with biliary tract cancer and mid-teens royalty payments on net sales of XERMELO in biliary tract cancer. The Company has determined that these amounts are constrained until the achievement, if any, of specific events. If or when the constraint is determined to be resolved, the Company will re-evaluate the overall gain in connection with the XERMELO sale and recognize an adjustment on a cumulative catch-up basis in the period that the determination is made. Such adjustment would be included in Gain on sale of XERMELO in the consolidated statement of comprehensive income (loss). The XERMELO sale did not meet the criteria for reporting discontinued operations as there was not a strategic shift that has (or will have) a major effect on the Company’s operations. For the years ended December 31, 2020 and 2019, the pretax net loss on the condensed consolidated statement of comprehensive income (loss) for the Company’s XERMELO operations is $12.2 million, and $15.4 million, respectively. As a result of the XERMELO sale, the Company implemented a reduction in force which reduced its workforce by approximately fifty percent. The Company incurred and recognized severance charges of approximate $5.5 million. Of this charge, $2.5 million was recorded in research and development expense and $3.0 million was recorded in selling, general and administrative expense in the accompanying consolidated statement of comprehensive income (loss) for the year ended December 31, 2020.
