Capitalized terms used but not defined in this supplement have the meanings set forth in the Note Prospectus.

The Starting Value for the notes was defined in the final Term Sheet dated June 29, 2023 (the “Final Term Sheet”). The Starting Value was defined as the lowest closing level of the Market Measure on any Market Measure Business Day (subject to adjustment as set forth in the Final Term Sheet) during the Starting Value Determination Period. The closing level of the Market Measure on June 29, 2023, the first day of the Starting Value Determination Period, was 4,396.44.
