Restricted Stock financial

"Represents the number of shares of Restricted Stock awarded for current year."

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

vested financial

"Represents the number of shares of Restricted Stock originally awarded that have now vested."

tax withholding obligations financial

"after choosing to surrender shares back to Issuer to satisfy the tax withholding obligations that arose"
