Key Terms

5 terms

performance shares financial

"as a result of the Issuer's Board ... certification to the achievement of 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.

restricted shares financial

"Each restricted share represents a contingent right to receive one common share minus withholding taxes."

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.

dividend equivalent units financial

"including any accrued dividend equivalent units ... dividend equivalent units with respect to restricted shares accrued upon approval by the 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.

vesting financial

"These shares vest 20%, 30% and 50% on the first three anniversaries of the grant date"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

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.
