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 On January 7, 2025, the Reporting Person filed a Form 4 which inadvertently reported the incorrect number of shares sold on January 6, 2025 pursuant to a Rule 10b5-1 trading plan (the "Original Form 4"). The Original Form 4 reported a sale of 5,000 shares and this Form 4 amendment is being filed to report the correct number of shares sold as 1,838.
