During the fourth quarter of fiscal 2024, none of our directors or Section 16 officers adopted orterminated any “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement” (as each term is defined an Item 408(a) of Regulation S-K).

On October 24, 2024, the Company and Karen J. Holcom, the Company’s Senior Vice President and Chief Financial Officer, entered into a fourth amendment to Ms. Holcom's Severance Agreement. The amendment modified the calculation of the minimum bonus component of severance that would be payable to Ms. Holcom on a qualifying termination of employment by replacing its reference to a specified percentage of Ms. Holcom's base salary (100%) with a reference to Ms. Holcom's target annual incentive bonus as in effect at the time of her termination. The foregoing description of the amendment to Ms. Holcom's Severance Agreement is a summary only and is qualified in its entirety by the full text of the amendment, which is filed as Exhibit 10(iii)A(43) to this Annual Report on Form 10-K.
