Employee Stock Purchase Plan financial

"purchased and held under the issuer's Employee Stock Purchase Plan"

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.

American Depositary Share financial

"Each American Depositary Share represents five (5) Common Shares"

An American Depositary Share (ADS) is a U.S.-listed certificate that represents a specified number of shares in a foreign company, held by a custodian bank; it works like a receipt that allows U.S. investors to buy and trade foreign equity on American exchanges without dealing with another country’s markets. Investors care because ADSs make foreign stocks easier to access, improve liquidity and settlement in dollars, and can affect dividend payments, voting rights and regulatory oversight compared with buying the underlying foreign shares directly.

New Taiwan dollars financial

"average purchase price of NT$2,309.9996 in New Taiwan dollars"

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.
