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.

ESPP trust financial

"Common Shares purchased and held under the issuer's Employee Stock Purchase Plan ("ESPP")."

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

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

indirect ownership financial

"Indirect holdings reported through an ESPP trust, LTI trust, and spouse"
