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.
Age 62 Plan financial
"These shares represent awards under the Age 62 Plan, a nonqualified deferred compensation plan of the Company."
Non-qualified Stock Option financial
"One-third of this stock option becomes exercisable on each of the 3rd, 4th, and 5th anniversaries of the grant date."
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."
nonqualified deferred compensation plan financial
"These shares represent awards under the Age 62 Plan, a nonqualified deferred compensation plan of the Company."
