"cash in an amount equal to the fair market value of one share of common stock"

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.

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.
