Explanation of Responses:
(1)	Represents shares withheld by the Issuer in satisfaction of the applicable withholding taxes due in connection with the vesting of restricted share units and delivery of the converted common shares.
(2)	Represents the conversion of restricted share units into common shares of the Issuer. These restricted share units were previously vested and deferred under the Issuer's Deferred Compensation Plan.

As a result, the award shall vest 25% per year over the four-year period following the date of grant. The common shares are reported on Table I.
