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"

investment control financial

"over which the filer has obtained investment control"

indirect ownership financial

"designated as indirect ownership, including holdings by trusts and spouse"
