American Depositary Shares financial
"American Depositary Shares (TSM) are listed as a direct holding."
American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.
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
"Common Shares (2330.TW) with nature of ownership reported as By ESPP Trust."
Immediate Family Member financial
"Common Shares (2330.TW) indirectly owned, reported as By Immediate Family Member."
