Key Terms

restricted stock, independent directors, annual grant

3 terms

restricted stock financial

"Represents an annual grant of restricted stock to independent directors."

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.

independent directors financial

"Represents an annual grant of restricted stock to independent directors."

Members of a company’s board who do not have significant business, family, or financial ties to the company and are not part of its management; they are chosen to provide impartial oversight of strategy, financial reporting, executive pay and risk. They matter to investors because independent directors act like an objective referee, helping ensure decisions favor shareholders’ long-term interests rather than insiders, which can strengthen trust and reduce the chance of mismanagement or conflicts of interest.
