"Stock Option (Right to Buy)"

10b5-1 trading plan regulatory

"sales were effected pursuant to a 10b5-1 trading plan"

A 10b5-1 trading plan is a pre-arranged strategy that allows company insiders to buy or sell company stock at set times, regardless of their current knowledge about the company's situation. It acts like a scheduled appointment for trading, helping prevent the appearance of impropriety or insider trading. This plan provides a way for insiders to sell or buy shares in a controlled, transparent manner, offering reassurance to investors about fair trading practices.

weighted-average price financial

"The price reported in Column 4 is a weighted-average price"

Weighted-average price is the average of multiple prices where each price is counted according to its size or importance—larger trades carry more weight than smaller ones, like averaging course grades by credit hours. It matters to investors because it gives a more realistic picture of the true price paid or received, helping assess trade execution, compare performance, calculate cost basis, and value positions more accurately than a simple average.
