Phantom Stock financial
"Each share of phantom stock represents a right to receive one share of Gallagher common 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.
Non-qualified Stock Option financial
"Non-qualified Stock Option ... underlying security title: Common Stock ... exercise price: 86.1700"
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
"Each notional stock unit represents a right to receive one share of Gallagher common stock."
tax-withholding disposition financial
"transaction_action: "tax-withholding disposition" ... Payment of exercise price or tax liability by delivering securities"
A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.
nonqualified deferred compensation plan financial
"awards under the Age 62 Plan, a nonqualified deferred compensation plan of the Company"
