Merger cash price $31.50 per share Used to determine cash-out value of RSUs and stock options
restricted stock unit financial
"Each restricted stock unit represents a contingent right to receive one share"
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.
stock option financial
"each reported stock option ("Option") was cancelled and converted into the right"
A stock option is a contract that gives you the right to buy or sell a company's stock at a specific price within a certain time frame. People use them to potentially make money if the stock's price moves favorably or to protect against losses. It's like holding a coupon that can be used to buy or sell stock at a set price later on.
tax withholdings financial
"cash payment (without interest, and less applicable tax withholdings and other"
exercise price financial
"excess of $31.50 per share over the per-share price of such Option"
The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.
contingent right to receive financial
"represents a contingent right to receive one share of the Issuer's common"
