Key Terms

stock option award agreement, vesting, beneficial ownership, pecuniary interest

4 terms

stock option award agreement financial

"pursuant to the terms and conditions of a stock option award agreement"

A stock option award agreement is a legal document that gives a person the right to buy a company’s shares at a fixed price later, with clear rules about when those rights become usable, how long they last, and any conditions for exercising them. For investors it matters because these agreements can increase the total shares outstanding and affect company costs and incentives—like a coupon that can turn into new stock, changing ownership and future stock supply.

vesting financial

"These options vest in 12 equal installments"

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.

beneficial ownership regulatory

"disclaims beneficial ownership of such shares"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

pecuniary interest financial

"except to the extent of his pecuniary interest therein"
