        <footnote id="F1">Represents 173.00 shares elected to be received in lieu of annual cash retainer, payable quarterly in advance, and annual cash committee retainers payable in advance for the third quarter of fiscal year 2021 and 52 shares elected to be received in lieu of annual cash retainer, payable quarterly for the second quarter of fiscal year 2021 (&quot;Additional Second Quarter Shares&quot;), all in accordance with prior election under the Non-Executive Director Compensation Plan and the U.S. Deferred Compensation Plan. The receipt of these shares has been deferred pursuant to the Non-Executive Director Compensation Plan. The Additional Second Quarter Shares should have been issued on March 31, 2021 as a result of the election made by the director, in addition to the shares reported in the Form 4 filing made at that time, but were not due to a computational error.</footnote>
