The Company’s corporate headquarters in Boca Raton met the criteria to be classified as held for sale during the third quarter of 2022. The asset was measured at the lower of its carrying amount or estimated fair value less costs to sell upon classification to held for sale, which was $104 million, and did not result in any valuation reserve being recorded. Accordingly, the Company presented its corporate headquarters in Boca Raton within current assets held for sale in the Consolidated Balance Sheets as of December 31, 2022. The Company has entered into an agreement in principle with a third-party buyer to sell this facility. The completion of the sales transaction, which is expected to occur in the first half of 2023, is subject to various conditions, including an intention for the Company to lease back a portion of the building’s office space from the new owner.
