5 terms
Restricted Stock Units financial
"in connection with the vesting of Restricted Stock Units. These sales are mandated"
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.
sell to cover financial
"tax withholding obligation to be funded by a "sell to cover" transaction and do not"
Sell to cover is when a person who receives company stock through options or awards sells just enough shares immediately to pay required taxes, exercise costs, or fees, keeping the rest. Think of it like cashing part of a bonus to cover the tax bill so you can keep the remainder. For investors, it can create predictable small selling pressure and slightly change the number of shares actually held by insiders without increasing long‑term dilution.
equity incentive plans financial
"mandated by the Issuer's election under its equity incentive plans to require the satisfaction"
Equity incentive plans are company programs that pay employees, executives, or directors with company stock, stock options, or share units instead of or in addition to cash, aiming to align their interests with shareholders—like giving team members a stake in the house they help build. For investors this matters because such plans can motivate better company performance but also dilute existing ownership and increase reported compensation costs, so they affect future earnings, voting power, and share value.
