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.

Long-Term Incentive (LTI) Bonus Plan financial

"cash received under the issuer’s Long-Term Incentive (LTI) Bonus Plan"

investment control financial

"over which the filer has obtained investment control"

average purchase price financial

"translated from the average purchase price of NT$2,524.2277"
