Goodwill And Intangible Assets Disclosure [Abstract] |
Sale of Intellectual Property | 9. Sale of Intellectual Property On April 12, 2017 the Company entered into an agreement to sell certain oncology assets and patents to Fosun. Fosun paid the Company a one-time nonrefundable payment of $0.6 million net of taxes in June 2017 and is required to pay royalties on net sales of products by Fosun and its affiliates and other consideration based on revenues from any licensees. The Company determined that the sale of the assets did not constitute a business and accordingly accounted for the transaction as a sale of assets. The Company evaluated the accounting for the payments received in 2017 under the multiple element accounting guidance and recorded the $0.6 million in payments received in revenue – other in the accompanying consolidated financial statements during the second quarter of 2017 as the deliverables under the agreement were substantially delivered as of June 30, 2017. See Note 2 — Summary of Significant Accounting Policies for additional information on the Company’s accounting for multiple element arrangements. The Company also evaluated the accounting for royalties and other consideration in the agreement. Since the amount of product that Fosun will ultimately be able to sell upon successfully utilizing this technology is uncertain, no royalty revenue will be recognized until such time when Fosun or its affiliates sell product to a third party and royalties are due to the Company.
