Deferred Stock Units financial

"The deferred stock units ("DSUs") represent the portion of the reporting person's annual equity award..."

Deferred stock units are promises from a company to give an employee shares of stock at a future date, often after certain conditions are met or after leaving the company. They function like a form of delayed compensation, allowing employees to earn shares over time. For investors, they represent potential future ownership in the company, but do not provide immediate voting rights or dividends until the shares are actually received.

dividend equivalents financial

"DSUs earn dividend equivalents when dividends are declared on the Company's common stock."

Payments tied to employee or contractor equity awards that mirror the cash dividends paid on the company’s stock; they give the holder the same economic benefit as owning the shares without transferring actual shares—often paid in cash or additional award units when the award becomes payable. Investors care because these payments affect a company’s compensation costs, cash flow and potential share dilution, and they signal how management is being rewarded and aligned with shareholders.

change in control financial

"payable ... at the earlier of the reporting person's separation from service or a change in control."

A "change in control" occurs when the ownership or management of a company shifts significantly, such as through a merger, acquisition, or sale of a large part of its assets. This change can impact how the company is run and may influence its future direction. For investors, it matters because it can affect the company's stability, strategy, and value, often signaling potential changes in investment risk or opportunity.

Non-Employee Director Deferred Compensation Plan financial

"deferred pursuant to the Company's Amended and Restated Non-Employee Director Deferred Compensation Plan."
