restricted stock financial

"provides for the issuance of restricted stock with a value of $37,500"

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.

non-employee director compensation program financial

"The non-employee director compensation program adopted by the Board in May 2011"

average closing price financial

"The price per share was based on the average closing price during June 2026"

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.
