(the “notes”)

This document (the “supplement”) supplements the Note Prospectus in connection with any secondary market transactions in the notes by us, CIBCWM or any of our other 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 20, 2021 (the “Final Pricing Supplement”) as the arithmetic average of the Closing Level of the Index on each scheduled Trading Day from and including December 17, 2021 to and including December 30, 2021, excluding any scheduled Trading Day on which a Market Disruption Event occurs.

The determination period for the Initial Level expired on December 30, 2021. The arithmetic average of the Closing Level of the Index on each scheduled Trading Day from and including December 17, 2021 to and including December 30, 2021 was 4,712.17, rounded to two decimal places.

Therefore, the Initial Level for the notes is 4,712.17.
