    <ffd:OfferingNote contextRef="offrl_1" id="ixv-381">Proposed maximum offering price per unit is estimated solely for the purpose of calculating the registration fee pursuant to Rule 457(c) under the Securities Act of 1933, as amended (the "Securities Act"). The offering price per share and aggregate offering price are based upon the average of the high and low prices per share of the registrant's Common Stock, as reported on the New York Stock Exchange, on April 29, 2026, a date within five business days prior to the filing of this prospectus supplement. This "Calculation of Registration Fee" table shall be deemed to update the "Calculation of Registration Fee" table in the registrant's Registration Statement on Form S-3ASR (File No. 333-277698), which was filed on March 6, 2024, in accordance with Rules 456(b) and 457(r) under the Securities Act. The prospectus supplement to which this exhibit is attached is a final prospectus for the related offering.</ffd:OfferingNote>
