This document (the “supplement”) supplements the Note Prospectus in connection with any secondary market transactions in the notes by us, the agent or any of our respective affiliates. Certain terms used but not defined in this supplement have the meanings set forth in the Note Prospectus.

The Initial Level for the notes was defined in the final pricing supplement dated December 6, 2023 (the “Final Pricing Supplement”) as the arithmetic average of the Closing Level of the Index on each scheduled Trading Day from and including December 4, 2023 to and including March 5, 2024, excluding any scheduled Trading Day on which a Market Disruption Event occurs.

The determination period for the Initial Level expired on March 5, 2024. The arithmetic average of the Closing Level of the Index on each scheduled Trading Day from and including December 4, 2023 to and including March 5, 2024 was 4,850.581.

Therefore, the Initial Level for the notes is 4,850.581.
