    The TWSE listed company shall at all times assess the status of its achievement of the aforementioned forecast information. If the assessment reveals any likelihood that it cannot be achieved, it shall immediately make an announcement of material information on the MOPS, and explain that the aforementioned forecast information is no longer applicable. If subsequently the TWSE listed company wishes to update (or correct) the aforementioned forecast information, it shall separately holds an investor conference, or hold a press conference pursuant to the Taiwan Stock Exchange Corporation Procedures for Verification and Disclosure of Material Information of Companies with Listed Securities, or handle the matter pursuant to the Regulations Governing the Publication of Financial Forecasts of Public Companies.
