Employee Stock Purchase Plan financial

"Common Shares purchased by the administrator of the issuer's Employee Stock Purchase Plan"

An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.

Long-Term Incentive ("LTI") Bonus Plan financial

"Represents Common Shares purchased by a trust with cash received under the issuer's Long-Term Incentive"

American Depositary Shares financial

"Each American Depositary Share represents five (5) Common Shares"

American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.
