weighted average sale price financial
"The reported price in Column 4 is a weighted average sale price."
restricted stock units financial
"Includes 56,645 RSUs that have not yet vested, 676 shares held"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
deferred compensation plan financial
"40,348 shares, the receipt of which has been deferred under the issuer'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.
401(k) plan financial
"676 shares held in the issuer's 401(k) plan, and 40,348 shares"
A 401(k) plan is a workplace retirement account that lets employees set aside part of their pay into a tax-advantaged savings pot, often with employers adding matching contributions — like a workplace piggy bank for future income. It matters to investors because the amount people save and how employers fund these plans influence consumer spending, corporate payroll costs and the flow of money into financial markets, which can affect stock prices and company valuations.
