Buy Plan / Sale Plan: These are also open market purchases/sales of shares, but in this case the transaction is part of a trading plan. Rule 10b5-1 allows insiders to setup a trading plan to buy/sell stocks over a certain period of time. Since the purchases/sales are predetermined, this protects the insiders from violating insider trading law.

Transaction was made pursuant to a contract, instruction or written plan for the purchase or sale of equity securities of the issuer that is intended to satisfy the affirmative defense conditions of Rule 10b5-1(c).

Explanation of Responses:

Id	Content
F1	The sale of shares was effected pursuant to a Rule 10b5-1 plan adopted by the reporting person on December 7, 2022.

Remarks:

This amendment is being filed solely to correct the transaction date in Column 2 of Table I originally filed by the reporting person on October 3, 2023.
