The number of shares of common stock that will be delivered for each performance stock unit depends on the achievement of certain performance factors. Depending on actual performance, the number of shares of common stock delivered upon the vesting date (based on the terms outlined in the respective award agreement) can range from 0% to 150% of the number presented above. The restricted stock units are subject to vesting over three years with one third, rounded down to the nearest whole share of stock, vesting in each period. The dividend equivalent units will vest proportionately with the underlying restricted stock units to which they relate.

Performance Stock Units financial
"Each performance stock unit converts into one share of common stock."
Performance stock units are a type of company award that grants employees shares of stock only if certain performance goals are met. They motivate employees to work toward specific company achievements, aligning their interests with those of shareholders. For investors, they can influence a company's future stock supply and reflect management’s confidence in reaching key targets.
Restricted Stock Units financial
"The restricted stock units are subject to vesting over three years."
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
Dividend Equivalent Units financial
"The dividend equivalent units will vest proportionately with the underlying units."
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.
tax-withholding disposition financial
"Payment of exercise price or tax liability by delivering securities."
A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.
