        <footnote id="F1">In May 2016 the Reporting Person was granted share units (sometimes called performance shares) under the Company's LTIP.  The May 2016 share units, which are contingent on continued employment through the second anniversary of the date of grant, once earned are payable in common shares on a one-for-one basis.  The May 2106 grant was earned (vested) on May 10, 2018 on paid in common shares.</footnote>
        <footnote id="F2">This amount represents grants made to the Reporting Person under the Company's Long-Term Incentive Plan in 2016, 2017 and 2018 of either (i) share units, which are time-based, and paid on a one-for-one basis in common shares on the third anniversary from the date of grant if the Reporting Person is still then employed by the Company, and (ii) performance shares, which are time-based and Company performance-based, and are also paid, if earned, on a one-for-one basis in common shares on the third anniversary from the date of grant if the Reporting Person is still then employed by the Company and based on the Company's performance over a three year performance period.</footnote>
