Non-qualified Stock Option financial
"security_title: "Non-qualified Stock Option""
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.
Notional Stock Units financial
"security_title: "Notional Stock Units""
Phantom Stock financial
"security_title: "Phantom Stock""
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.
Age 62 Plan financial
"awards under the Age 62 Plan, a nonqualified deferred compensation plan"
nonqualified deferred compensation plan financial
"a nonqualified deferred compensation plan of the Company"
A nonqualified deferred compensation plan is an arrangement where an employer lets select employees postpone receiving part of their pay or bonuses until a future date, often at retirement, so taxes are paid later. It matters to investors because these payouts are typically unsecured promises by the company—like an internal IOU—so they create future cash obligations and expose the company to extra liability risk if the business falters, and they also reveal how executives are being paid and motivated.
