Big tip.. but what is it?

We have this already, don't we?

Yes but this is now more explicit in the code of ethics

What's so important about it?

It explicitly allows professional accountants (including auditors) to break confidentiality if the public interest and report to authorities

Why is that?

It's an attempt to improve the reputation of accountants and auditors in the battle against fraud, corruption, money laundering etc.

Where can I find more info?
