Ann: IOOF response to APRA notice and action, page-107

I'd say it's due to a few things.

1. This is a very big deal, they basically knowingly broke the law, because they felt like it and it was good for business.
2. The RC will have a huge effect of banking in this country for at least the next 5 years. New reforms, tighter regulation, less profitability etc etc.

3. And similar to the last point, it's going to be really hard to make money in this country on anything to do with banking, financial services and Insurance. That's due to the rate environment we are in, low wage growth and low inflation.

Banking and Financial services are just going to be really hard areas to see earnings growth over the foreseesable future.
The banks have been selling their Insurance and Financial service arms for a reason. They want to stick to core business service lines and run a very lean and tight ship with tightening capital requirements and increased regulation.
