Explanation of Responses:

Id	Content
F1	On August 19, 2025, the Reporting Person filed a Form 4 incorrectly reporting that the Reporting Person's 2024 Irrevocable Trust beneficially owned non-derivative securities. This amendment correctly states the amount of non-derivative securities beneficially owned by the Reporting Person.
