Non-qualified Stock Option financial
"Non-qualified Stock Option expiring in March 2027"
A non-qualified stock option (NSO) is a contract that lets an employee or service provider buy company shares at a fixed price for a set period, like a voucher to purchase stock later at today’s price. It matters to investors because exercising NSOs creates ordinary income for the holder and can increase share count, affecting a company’s earnings and ownership mix; think of it as a future sale that can dilute existing shareholders and has immediate tax consequences for the recipient.
phantom stock financial
"Each share of phantom stock represents a right to receive one share"
A phantom stock is a form of compensation that gives employees or executives the benefits of stock ownership, such as the increase in stock value, without actually giving them real shares. It acts like a promise to pay the employee the equivalent value of company stock later, often as a bonus or incentive. This allows companies to motivate and reward staff without diluting ownership or transferring actual shares.
Notional Stock Units financial
"Each notional stock unit represents a right to receive one share"
Age 62 Plan financial
