Employee Stock Purchase Plan financial

"Common Shares purchased and held under the 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.

ESPP Trust financial

"total shares following transaction 120.0000, indirect ownership by ESPP Trust"

indirect ownership financial

"Ownership type reported as indirect with nature of ownership by ESPP Trust"

average purchase price financial

"The price was translated from the average purchase price of NT$2,367.1117"

New Taiwan dollars financial

"average purchase price of NT$2,367.1117 in New Taiwan dollars, at the rate of NT$32.288"

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. Changes in the currency’s strength can also impact international trade and financial markets involving Taiwan.
