restricted stock unit financial

"Each restricted stock unit represents a contingent right to receive one share"

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

FICA tax financial

"Shares withheld for FICA tax for retirement eligible executives"

dividend share equivalents financial

"Includes dividend share equivalents, accrued quarterly"

Deferred Compensation Plan financial

"pursuant to 3M's 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.
