The Australian Stock Exchange listing rules include ‘continuous disclosure’ provisions.
The general rule (3.1) is that “Once an entity is or becomes aware of any information concerning it that a reasonable person would expect to have a material effect on the price or value of the entity’s securities, the entity must immediately tell ASX that information”.
Does that include significant accidents? Maybe, as it might fit under the general rule. Maybe not. The listing rules give a set of “non-exhaustive” examples. Significant accidents, incidents, new risks, notices given by regulators, etc are not among these examples. Should they be?
