Key Terms

4 terms

10b5-1 trading plan financial

"made pursuant to a 10b5-1 trading plan"

A 10b5-1 trading plan is a pre-arranged strategy that allows company insiders to buy or sell company stock at set times, regardless of their current knowledge about the company's situation. It acts like a scheduled appointment for trading, helping prevent the appearance of impropriety or insider trading. This plan provides a way for insiders to sell or buy shares in a controlled, transparent manner, offering reassurance to investors about fair trading practices.

weighted average sale price financial

"The price reported in Column 4 is a weighted average sale price"

sell to cover financial

"funded by a "sell to cover" transaction"

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.

restricted stock units financial

"arising as a result of the release of restricted stock units"

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.
