restricted stock units ("RSUs") financial
"Represents an annual grant of restricted stock units ("RSUs") granted under the Company's Stock Incentive Plan"
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
Stock Option (Right to Buy) financial
"Consists of stock options granted under the Company's Stock Incentive Plan"
Stock Incentive Plan financial
"granted under the Company's Stock Incentive Plan, as amended and restated, for Board and Committee service"
A stock incentive plan is a company program that gives employees or directors pieces of ownership or the right to buy shares over time, similar to receiving a bonus paid in company stock instead of cash. Investors pay attention because these plans align staff incentives with long‑term company performance but can also dilute existing shareholders and affect reported profits when grants are expensed, so they influence both ownership percentages and financial results.
Black-Scholes value financial
"dividing by the Black-Scholes value of a single option calculated as of the date of the grant"
