4 terms

NQOs technical

"Stock Options (Right to Buy NQOs)"

dividend reinvestment financial

"Includes acquisition of shares pursuant to dividend reinvestment."

Dividend reinvestment is when the money earned from a company's profit sharing, called dividends, is automatically used to buy more shares of that company instead of being received as cash. This process helps investors grow their holdings over time without extra effort, much like using earned interest to buy more of a savings account. It encourages long-term investment growth by continuously increasing the amount of shares owned.

substantially equal installments technical

"Options become exercisable in three substantially equal installments"

withholding financial

"option shares may be used to satisfy withholding"
