Explanation of Responses:

Id	Content
F1	This report reflects the rescission of the sale previously reported on December 10, 2025, which was reported to have occurred on December 9, 2025. The transaction was rescinded because the broker failed to timely file a Notice of Proposed Sale under Rule 144(h), a necessary condition to the completion of the sale. On March 6, 2026, following discovery of this error, the broker rescinded the previously reported sale through its broker's error account and effected a sale of the same number of shares at the same price as the rescinded transaction.
