                                            Registrant is relying upon Rule 457(c) under the Securities Act of 1933 (&#x201c;Securities
                                            Act&#x201d;) 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 June 11, 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.</ffd:OfferingNote>
