Immediate public disclosure of the information in question must be effected if the issuer should learn that insider trading, as defined in Article 57 hereof, has taken, or is taking place. In unusual cases, where the trading is insignificant and did not have any influence on the market, and measures sufficient to halt the insider trading and prevent its recurrence have already been taken, exceptions could be made which should be discussed with the Agency. The Agency can provide current information regarding market activity in the issuer's securities with which to help assess the significance of such trading.
