restricted stock financial
"Grant to the reporting person of restricted stock under the Kaiser Aluminum Corporation 2021 Equity and Incentive Compensation Plan"
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.
2021 Equity and Incentive Compensation Plan financial
"under the Kaiser Aluminum Corporation 2021 Equity and Incentive Compensation Plan, as amended and restated"
annual cash retainer financial
"in lieu of all or a portion of the reporting person's annual cash retainer for serving as a member of the Board of Directors"
average closing price financial
"Equal to the average closing price of the Issuer's common stock as reported by the Nasdaq Stock Market, LLC for the 20 trading days prior"
The average closing price is the arithmetic mean of a security’s end-of-day prices over a chosen period, found by adding each day’s closing price and dividing by the number of days. It smooths out daily ups and downs to show a typical market value—like averaging daily temperatures to understand a month’s climate—and helps investors spot trends, judge whether a stock is generally rising or falling, and make clearer buy or sell decisions.
