        <footnote id="F3">Each unit represents a contingent right to receive one share of Company common stock.</footnote>
        <footnote id="F4">The number of shares acquired upon vesting of the performance-based stock units is contingent upon the achievement of pre-established performance metrics, approved by the Compensation Committee, over a three-year performance period (fiscal 2018-2020) and continued employment through the end of the performance period. The number of shares reflected is at the target award amount. No stock units will vest below a minimum level of performance. At or above the minimum level of performance, the actual number of vested shares may range from 0% to 200% of the target award amount. In the event of termination before the end of the performance period due to death, disability or retirement at or after age 62 with at least five years of service, a proportionate number of shares will vest based on the number of days employed to total days during the performance period.</footnote>
