Employee Stock Purchase Plan financial

"issuer's Employee Stock Purchase Plan ("ESPP")"

An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.

average purchase price financial

"translated from the average purchase price of NT$2,309.9996"

New Taiwan dollars financial

"in New Taiwan dollars, at the rate of NT$32.768 to US$1"

The New Taiwan Dollar (NTD) is the official currency used in Taiwan for everyday transactions, like buying groceries or paying bills. For investors, it matters because its value can influence Taiwan’s economy and affect the profitability of investments related to the region.
