In addition, the $400 million authorization does not include shares repurchased in connection with the administration of employee share-based compensation plans.

Canadian Securities Law Exemption

The Company has received an exemption decision issued by the Ontario Securities Commission dated April 1, 2022 for relief from the formal issuer bid requirements under Canadian securities laws. The exemption decision permits the Company to repurchase up to 15% of its outstanding common shares in any 12-month period through the facilities of the New York Stock Exchange (“NYSE”) under repurchase programs that the Company may implement from time to time. Canadian securities laws regulate an issuer’s ability to make repurchases of its own securities.

The decision allows the Company to make repurchases under its repurchase programs from time to time in excess of the maximum allowable in reliance on the existing “other published markets” exemption from the formal issuer bid requirements available under Canadian securities laws. The “other published markets” exemption caps the Company’s ability to repurchase its securities through the facilities of the NYSE at 5% of the issuer’s outstanding securities during any 12-month period.

The conditions of the exemption decision are as follows: (i) any repurchases made in reliance on the exemption decision must be permitted under, and part of, repurchase programs established and conducted in accordance with United States securities laws and NYSE rules, (ii) the aggregate number of common shares acquired in reliance on the exemption decision and the “other published markets” exemption by the Company and any person acting jointly or in concert with the Company within any period of 12 months does not exceed 15% of the outstanding common shares at the beginning of the 12-month period, (iii) the common shares are not listed

and posted for trading on an exchange in Canada, (iv) the exemption decision applies only to the acquisition of common shares until April 1, 2025, (v) at least 5 days prior to purchasing common shares in reliance on the exemption decision, the Company discloses the terms of the exemption decision and the conditions applicable thereto in a press release that is issued and filed on the System for Electronic Document Analysis and Retrieval (“SEDAR”) and includes such information as part of the news release required to be issued in accordance with the “other published markets exemption” in respect of any repurchase program that may be implemented by the Company, which this press releases satisfies, and (vi) the Company does not acquire common shares in reliance on the “other published markets” exemption if the aggregate number of common shares purchased by the Company and any person acting jointly or in concert with the Company within any period of 12 months exceeds 5% of the outstanding Shares at the beginning of the 12-month period .
