Reading guide
Robin argues that material information announcements on the Market Observation Post System should be factual and restrained. If a company wants to celebrate how wonderful it is, he suggests buying media space: Taiwanese readers and investors cannot distinguish a journalist's reporting from a company's promotional copy, and media outlets need advertising budgets to survive. Announcements on the exchange-supervised disclosure platform, however, must take the regulator's approach and standards into account. In the example, passive-component manufacturer YAGEO issued a September 26 announcement titled “YAGEO Group AI Summit Concludes Successfully, with Every Seat Filled.” On October 7, the Taiwan Stock Exchange imposed an NT$200,000 contractual penalty because material information announcements must not contain advertising-like statements. It reiterated that such disclosures must not provide unconfirmed information, expound management philosophy, or serve as an advertising platform.
Key points
- Material information disclosures should be factual and restrained; promotional material belongs in paid media.
- The YAGEO example: an AI forum announcement resulted in an NT$200,000 contractual penalty in October 2024.
- TWSE rules prohibit using material information disclosures to expound management philosophy, provide unconfirmed information, or advertise.
