Assets Held for Sale	(7) Assets Held for Sale On January 12, 2021, the Company and Catalent entered into an asset purchase agreement, pursuant to which the Company agreed to sell to Catalent certain assets related to the Company’s manufacturing activities located at the facilities situated in Chelsea, Massachusetts (the “Chelsea Facility”) and Waltham, Massachusetts (the “Waltham Facility”), for a purchase price of $80 million, plus an additional $2.3 million for raw materials transferred, and the assumption by Catalent of certain liabilities relating to such manufacturing activities. The Company closed the transaction on February 10, 2021. The Company determined that the criterion to classify the Chelsea manufacturing operations as assets held for sale within the Company’s consolidated balance sheet effective December 31, 2020 were met. Accordingly, the assets were classified as current assets held for sale at December 31, 2020 as the Company, at that time, expected to divest the Chelsea manufacturing operations within the next twelve months. The classification to assets held for sale impacted the net book value of the assets expected to be transferred upon sale. The estimated fair value of the Chelsea manufacturing operations was determined using the purchase price in the purchase agreement along with estimated broker, accounting, legal, and other selling expenses, which resulted in a fair value less costs to sell of approximately $71.8 million. The carrying value of the assets being classified as held for sale was approximately $129.7 million, which includes property and equipment of $129.6 million and prepaid expenses of $0.1 million. As a result, the Company recorded a loss on assets held for sale of $57.9 million against the Chelsea manufacturing operations. Upon completion of the divestiture, final net proceeds were $74.0 million. Additionally, the expected divestiture of the Chelsea Facility group was not deemed to represent a fundamental strategic shift that would have a major effect on the Company’s operations, and accordingly, the operating results of the Chelsea manufacturing operations were not reported as discontinued operations in the Company’s consolidated statement of income as of December 31, 2020.
