Phantom Shares financial

"Each phantom share is the equivalent of one Issuer common share."

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.
