        <footnote id="F1">On May 23, 2018, the reporting person was granted financial-based performance share units that would be measured over a three year time period. The payout could be increased to 200% of target or reduced to 0% based on achievement of the key metrics. The performance share units have been accumulating quarterly dividend equivalents. Based on company performance over the three period ending on December 31, 2020, the Compensation Committee certified on February 22, 2021 that the reporting person was entitled to 99.7% of his target opportunity.</footnote>
