The business supervisory body says that mining corporations need to make sure they obey permanent disclosure rules, when making statements all through the debate concerning the projected resources super profits tax.

The Australian Securities and Investments Commission says the Directors of resources Companies need to check whether they have an adequate amount of information to form a view on the impact of the tax, when stating statements to financial markets.

ASIC's Deputy Chairman, Belinda Gibson says accountability for obedience with the stock exchange's permanent disclosure rules eventually lies with Directors.

She said that norms need that the markets are totally informed and that they cannot be misguided by any source.

So, it is all dependent upon what kind of statements are made by directors related to their firms, if it is in relation with the resources tax, which what they say is appropriate and that all material information is provided to the market.
