performance shares financial
"performance for the performance shares granted in 2023"
Performance shares are a type of company stock given to executives or employees that only become theirs if the company meets specific goals, like hitting certain profits or growth targets. They motivate leaders to work toward the company’s success, because their additional shares depend on achieving these results.
dividend equivalent units financial
"including any accrued dividend equivalent units, as a result of the Issuer's Board"
Dividend equivalent units are bookkeeping credits that mirror cash dividends paid on actual shares, granted to holders of stock-based awards such as restricted stock units or deferred compensation. They matter to investors because they increase a company’s reported employee compensation cost and can lead to issuance of more shares or cash payouts over time, similar to extra pay linked to ownership that affects shareholder dilution and corporate cash flow.
restricted shares financial
"Each restricted share represents a contingent right to receive one common share"
Restricted shares are company stock that cannot be sold or transferred immediately because they are subject to legal or contractual limits, such as a required holding period or performance conditions. They matter to investors because these locked-up shares can affect a company’s available stock for trading, future dilution, and insider incentives—imagine a gift that can’t be cashed until certain conditions are met, which changes when and how much supply can suddenly enter the market.
withholding taxes financial
"Each restricted share represents a contingent right to receive one common share minus withholding taxes."
Withholding taxes are amounts a payer or government takes out of payments — such as wages, interest, or dividends — before the recipient gets the money, functioning like a cashier keeping part of a bill to pay taxes on your behalf. For investors this matters because it reduces the cash they actually receive, affects net returns and yield calculations, and may require additional paperwork or treaty claims to recover or offset the withheld amount against final tax bills.
contingent right financial
"Each restricted share represents a contingent right to receive one common share"
