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.

American Depositary Share financial

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

An American Depositary Share (ADS) is a U.S.-listed certificate that represents a specified number of shares in a foreign company, held by a custodian bank; it works like a receipt that allows U.S. investors to buy and trade foreign equity on American exchanges without dealing with another country’s markets. Investors care because ADSs make foreign stocks easier to access, improve liquidity and settlement in dollars, and can affect dividend payments, voting rights and regulatory oversight compared with buying the underlying foreign shares directly.

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

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