Ordinary Shares financial
"He directly holds 30,000 Ordinary Shares and two stock option grants"
Ordinary shares are a type of ownership stake in a company, giving shareholders a right to participate in the company’s profits and decision-making through voting. They are similar to owning a piece of a business, and their value can rise or fall based on the company's performance. Investors buy ordinary shares to potentially earn dividends and benefit from the company's growth over time.

"The November 23, 2018 option grant is described as fully vested and exercisable"
semi-annual installments financial
"The August 18, 2023 grant vests in seven semi-annual installments"
exercise price financial
"One option has an exercise price of NT$41.10 per share"
The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.
