(c) Director and Officer Trading Arrangements

A portion of our directors’ and officers’ compensation is in the form of equity awards and, from time to time, they may engage in open-market transactions involving Company securities for diversification or other personal reasons. All such transactions in Company securities by directors and officers must comply with the Company’s Insider Trading Policy, which requires that transactions be in accordance with applicable U.S. federal securities laws that prohibit trading while in possession of material nonpublic information. Rule 10b5-1 under the Exchange Act provides an affirmative defense that enables directors and officers to prearrange transactions in the Company’s securities in a manner that avoids concerns about initiating transactions while in possession of material nonpublic information. The Company’s Insider Trading Policy permits our directors and executive officers to enter into trading plans designed to comply with Rule 10b5-1.

The following table describes the contracts, instructions or written plans for the purchase or sale of securities adopted by our directors or officers (as defined in Rule 16a-1(f) under the Exchange Act) during the three months ended September 30, 2024, that are intended to satisfy the affirmative defense conditions of Rule 10b5-1(c). No other Rule 10b5-1 trading arrangements or "non-Rule 10b5-1 trading arrangements" (as defined by Regulation S-K Item 408(c)) were entered into or terminated by our directors or officers during such period.

(1)The plan duration is until the date listed in this column or such earlier date upon the completion of all trades under the plan (or the expiration of the orders relating to such trades without execution) or the occurrence of such other termination events as specified in the plan.
