Phantom Stock financial
"Each share of phantom stock is deemed invested in one share of NBT Bancorp Inc. 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.
Deferred Compensation Plan financial
"pursuant to the terms of the Deferred Compensation Plan"
A deferred compensation plan is an arrangement where an employer agrees to pay part of an employee’s pay or bonus at a later date instead of immediately, often to reduce current tax bills or to tie rewards to long-term performance. For investors it matters because these promises create future cash obligations and influence executive incentives and retention; they can affect a company’s reported liabilities, cash flow planning and the risk profile if the business faces financial trouble.
open-market sale financial
"transaction_code_description": "Sale in open market or private transaction""
An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.
401k financial
"nature_of_ownership": "401k""
An employer-sponsored retirement savings plan in the United States that lets workers set aside part of their paycheck into investments with tax advantages; some plans also include employer matching contributions, which is like free money added to your savings. It matters to investors because 401(k) balances represent a large pool of household retirement assets that influence personal financial security, investor behavior, and long-term demand for stocks and bonds.
