Employee Stock Purchase Plan financial

"Common Shares purchased by the administrator of 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.

ESPP financial

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

An Employee Stock Purchase Plan (ESPP) is a company program that lets employees buy the company’s shares at a reduced price, usually by setting aside a small portion of their pay over time. It matters to investors because it encourages employees to own part of the business—like giving staff a discounted membership— which can boost commitment and performance, while also potentially increasing the number of shares available and affecting shareholder value.

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