    <ffd:OfferingNote contextRef="offrl_1" id="ixv-381">The Registrant is relying upon Rule 457(c) under the Securities Act of 1933 ("Securities Act") to calculate the registration fee. The maximum aggregate offering price is estimated solely for purposes of determining the registration fee based on the average of the high and low sales prices of the shares of Common Shares, as reported by the New York Stock Exchange on May 15, 2026, in accordance with Rule 457(c) under the Securities Act. The proposed maximum offering price per security will be determined from time to time by the Registrant in connection with the sale by the Registrant of the securities registered under this Registration Statement.

No separate consideration will be received by the Registrant. Any shares issued pursuant to an offering of rights to purchase common shares, including any shares issued pursuant to an over-subscription privilege or a secondary over subscription privilege, will be shares registered under this Registration Statement.
