Trading conducted by the dealing department of the issuer for its own account and hedge trading conducted by it in connection with call (put) warrants issued by it may not affect the fairness of market prices or harm shareholder equity, and an effective internal control system shall be established and executed in connection with such trading.
An issuer of call (put) warrants shall issue a letter of report to the TWSE by the 5th of each month, providing information on purchases and sales of the underlying securities of its issued warrants by its dealing department for the preceding month (including the trading day, the name of the security and the volume of the transaction).
The provisions of the preceding two paragraphs will apply mutatis mutandis to the risk management institutions engaged by issuers using outsourced risk management, and, in the event of a foreign issuer, to the dealing department of its branch office within ROC territory or the dealing department of a branch office established within ROC territory by a directly or indirectly wholly-owned subsidiary of such a foreign institution.
Except where regulations provide otherwise, during the duration of the call (put) warrants, there may be no inter-account transfers of the warrants' underlying security between the issuer's dealing department and positions in the security held in the issuer's hedge accounts.
The "dealing department" referred to in the preceding four paragraphs includes any unit or trading account that is equivalent to a dealing department.
