Key Terms

restricted stock unit financial

"in connection with the vesting of restricted stock unit awards pursuant"

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

sell-to-cover arrangements financial

"in connection with the vesting of restricted stock unit awards pursuant to sell-to-cover arrangements"

weighted-average price financial

"reflect the aggregate number and weighted-average price, respectively, of shares sold"

Weighted-average price is the average of multiple prices where each price is counted according to its size or importance—larger trades carry more weight than smaller ones, like averaging course grades by credit hours. It matters to investors because it gives a more realistic picture of the true price paid or received, helping assess trade execution, compare performance, calculate cost basis, and value positions more accurately than a simple average.
