Phantom Shares financial

"These phantom shares were acquired through reinvestment of dividend equivalents"

Phantom shares are a form of employee or executive compensation that mimics the economic value of owning company stock without actually issuing real shares; holders receive cash or equivalent payments tied to the company’s share price or dividends. Think of it like a receipt that pays out if the stock rises — it aligns managers’ interests with shareholders but does not dilute ownership, while creating a future cash obligation that investors should watch as it can affect company cash flow and valuation.

dividend equivalents financial

"acquired through reinvestment of dividend equivalents under the CubeSmart Trust Executive Deferred Compensation Plan"

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.

Executive Deferred Compensation Plan financial
