Employee Stock Purchase Plan financial
"Common Shares purchased by the administrator of the issuer's Employee Stock Purchase Plan ("ESPP") on behalf of the filer"
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
"Represents Common Shares purchased by a trust with cash received under the issuer's Long-Term Incentive ("LTI") Bonus Plan"
trust financial
"Represents Common Shares purchased by a trust with cash received under the issuer's Long-Term Incentive ("LTI") Bonus Plan"
A trust is a legal setup in which one party (the trustee) holds and manages assets—like cash, stocks or property—on behalf of other people (beneficiaries) according to instructions from the person who created it (the grantor). Think of it as a locked box with a keyholder who must follow written rules; for investors it matters because trusts influence who controls and benefits from assets, affect taxes and succession, and can change how quickly or transparently shares are bought, sold or voted.
