Key Terms

3 terms

Restricted Share Unit financial

"Each restricted share unit ("RSU") represents a contingent right to receive one share"

A restricted share unit (RSU) is a promise by a company to give an employee a set number of company shares at a future date, typically after meeting time or performance conditions. For investors, RSUs matter because when they convert into actual shares they increase the number of shares outstanding (like unlocking more tickets in a game), which can dilute existing holders, and they align employee incentives with company performance, influencing behavior and long-term value.

tax withholding obligation financial

"shares of common stock withheld by the Issuer to cover the reporting person's tax withholding obligation"

Rule 10b5-1 regulatory

"No Rule 10b5-1 plan is reported for these transactions"

Rule 10b5-1 is a regulation that allows company insiders to buy or sell their shares at predetermined times, even if they have access to non-public information. It acts like setting a schedule in advance for transactions, helping prevent accusations of unfair trading. This rule provides a way for insiders to plan trades transparently, giving investors confidence that these transactions are not based on hidden information.
