Subsequent Events [Abstract] |
Subsequent Events | Subsequent Events On January 5, 2023, the Board of Directors of the Company approved the appointment of John C. Jacobs, as President and Chief Executive Officer and a member of the Board, effective as of January 23, 2023. Mr. Jacobs succeeded Stanley C. Erck, who provided the Board with notice on January 5, 2023 of his decision to retire as President and Chief Executive Officer and as a member of the Board, in each case effective as of January 23, 2023. On January 24, 2023, Gavi filed a demand for arbitration with the International Court of Arbitration based on claims stemming from the Gavi APA. Arbitration is inherently uncertain, and while the Company believes that it is entitled to retain the remaining Advance Payment Amount received from Gavi, it is possible that it could be required to refund all or a portion of the remaining Advance Payment Amount from Gavi (see Note 3 and Note 18). On January 31, 2023, the Company funded the outstanding principal amount of $325.0 million on the 2023 Notes, due February 1, 2023 and the indenture governing the 2023 Notes was subsequently satisfied and discharged in accordance with its terms. The Company’s related “capped call transactions” expired by their terms on January 27, 2023.
