Discontinued Operations and Disposal Groups [Abstract]
Sale of PerClot	Sale of PerClot Overview On July 28, 2021 we entered into an asset purchase agreement, Transitional Manufacturing and Supply Agreement (“TMSA”), and other ancillary agreements related to the sale of PerClot®, a polysaccharide hemostatic agent used in surgery (“PerClot”), to a subsidiary of Baxter International, Inc. (“Baxter”) and an agreement to terminate all of our material agreements with Starch Medical, Inc. (“SMI”) related to PerClot (collectively the “Baxter Transaction”). Under the terms of the Baxter Transaction, Baxter will pay an aggregate of up to $54.5 million in consideration (we will receive up to $41.0 million and SMI will receive up to $13.5 million), consisting of (i) $25.0 million at closing, of which $6.0 million was paid to SMI; (ii) $18.8 million upon our receipt of Premarket Approval (“PMA”) from the US Food and Drug Administration (the “FDA”) for PerClot and our transfer of the PMA to Baxter, of which $4.5 million was paid to SMI; and (iii) up to $10.0 million upon Baxter’s achievement of certain cumulative worldwide net sales of PerClot prior to December 31, 2026 and December 31, 2027, of which up to $3.0 million is payable to SMI. In addition, at the conclusion of our manufacturing and supply services for Baxter, Baxter will pay $780,000 upon transfer of our PerClot manufacturing equipment. Under the terms of the Baxter Transaction, we will continue to provide to Baxter certain transition services relating to the sale of SMI PerClot outside of the US. Within the terms of the TMSA, we will manufacture and supply PerClot for Baxter post PMA for a contractual period of 21 months, subject to short-term renewal provisions. Accounting for the Transaction Upon closing of the Baxter Transaction, we received $25.0 million from Baxter and paid $6.0 million to SMI. We derecognized intangible assets with a carrying value of $1.6 million and wrote-off $1.5 million of prepaid royalties previously recorded on our Consolidated Balance Sheets related to PerClot. Under the terms of the agreement, Baxter acquired intellectual property related to our development efforts for PerClot. We recorded a pre-tax gain of $15.9 million, included as Gain from sale of non-financial assets within the Consolidated Statements of Operations and Comprehensive Loss for the year ended December 31, 2021. The PerClot product line was included as part of our Medical Devices segment. PerClot PMA On May 23, 2023 the FDA granted PMA of PerClot for use to control bleeding in certain open and laparoscopic surgical procedures. Pursuant to the terms of the TMSA of the Baxter Transaction, we transferred the ownership of the PMA to Baxter following approval. In May 2023 we received a payment of $18.8 million from Baxter, of which $4.5 million was paid to SMI. As a result, we recorded a pre-tax gain of $14.3 million as the assets were derecognized upon closing of the Baxter Transaction in fiscal year 2021, which was included as Gain from sale of non-financial assets within the Consolidated Statements of Operations and Comprehensive Loss for the twelve months ended December 31, 2023. Following receipt of the PMA, under the terms of the TMSA, we began manufacturing and supplying PerClot for Baxter and recorded $5.1 million of PerClot revenues on the Consolidated Statements of Operations and Comprehensive Loss during the twelve months ended December 31, 2023. The Company accounted for this TMSA in accordance with the provision of ASU 2016-02, Leases Topic 842 (“ASC 842”) by bifurcating the lease and non-lease components and recognizing each component based on ASC 842 and ASU 2014-09, Revenue from Contracts with Customers Topic 606. The amount of lease revenue was $278,000 for the twelve months ended December 31, 2023.
