F1 Grant was initially made on October 22, 2024, subject to performance conditions concerning fiscal 2025, which have been deemed satisfied by the Compensation Committee of the Board of Directors. The earned awards vest 20% on the first anniversary of the grant date and an additional 20% vest over each of the ensuing four years based on continued employment with the Company. In addition, under the 2019 Incentive Plan, employees are eligible for accelerated vesting upon the anniversary of their 25th, 30th and 35th years of service.
F2 Not applicable. Grant of Restricted Stock Units.
F3 Upon a previous transfer of shares from one broker to another broker, a fractional share of .563 was liquidated by the broker transferring the shares due to an administrative inability to hold a fractional share in the account. Therefore, the total owned has been reduced by such amount.
