1. An issuer whose securities are admitted to official listing shall provide the competent authorities with all the information which the latter consider appropriate in order to protect investors or ensure the smooth operation of the market.

2. Where protection of investors or the smooth operation of the market so requires, an issuer may be required by the competent authorities to publish such information in such a form and within such time limits as they consider appropriate. Should the issuer fail to comply with such requirement, the competent authorities may themselves publish such information after having heard the issuer.
