Employee Stock Purchase Plan financial
"Common Shares purchased and held under the issuer's Employee Stock Purchase Plan ("ESPP")."
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 Bonus Plan financial
"Represents Common Shares purchased by a trust with cash received under the issuer's Long-Term Incentive ("LTI") Bonus Plan, over which the filer has obtained investment control."
