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.

Long-Term Incentive Bonus Plan financial

"purchased by a trust with cash received under the issuer's Long-Term Incentive ("LTI") Bonus Plan"

bona fide gift financial

"transaction code description shows the disposition as a Bona fide gift"

A bona fide gift is a genuine, voluntary transfer of money, property, or benefits from one party to another made without expectation of repayment, services, or hidden conditions. Investors care because such gifts can affect company disclosures, related‑party transaction rules, tax treatment, and perceived conflicts of interest; think of it like someone giving you a present with no strings attached — but on a corporate scale, auditors and regulators need to verify it really is unconditional.

indirect ownership financial

"Indirect holdings are reported as By LTI Trust and By ESPP Trust"

TSM VP Tzu-Sou Chuang reported a bona fide gift of 500,000 Common Shares (2330.TW). The shares were transferred at $0.0000 per share, indicating a non-market, no‑consideration disposition rather than an open‑market sale or purchase.

What indirect TSM share holdings are reported for Tzu-Sou Chuang in trusts?

Does the TSM Form 4 show any open-market buying or selling by Tzu-Sou Chuang?

No open-market buying or selling is shown; the only disposition is a bona fide gift of 500,000 shares at $0.0000 per share. The other entries are holdings through employee-related trusts, not new market transactions in TSM stock.

What does a bona fide gift transaction mean for TSM insider activity?
