Key Terms

restricted stock unit, fair market value, prorated, indemnification agreement

4 terms

restricted stock unit financial

"a restricted stock unit (“RSU”) award"

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.

fair market value financial

"with a fair market value of $220,000"

The price a willing buyer and a willing seller would agree on for an asset or security when neither is under pressure and both have access to the same information. Think of it as the market’s neutral estimate of what something is worth, like the price two neighbors would settle on for a car after comparing similar listings. Investors care because fair market value guides buying and selling decisions, tax reporting, portfolio valuation, and how accurately company assets are reflected in financial statements.

prorated financial

"prorated to reflect the number of months of service"

Prorated means dividing or allocating a quantity, cost, or benefit proportionally based on the amount of time or usage involved. For example, if a service fee is paid monthly but someone uses only part of the month, the fee is adjusted to reflect the actual time used. This ensures fairness by matching costs or benefits to the actual period or amount involved, which can impact how investors evaluate expenses, returns, or value.

indemnification agreement regulatory

"the Company’s standard form of indemnification agreement"

An indemnification agreement is a contract in which one party promises to cover losses, costs, or legal claims that another party might face, acting like a tailored safety net or private insurance policy. For investors, it matters because such agreements shift potential financial risk away from a company or its officers and onto the indemnifier, which can affect a company’s future liabilities, cash flow and how risky the investment appears during deal-making or litigation.
