Commonwealth Bank dealer groups have complied with most of the conditions imposed by the Australian Securities and Investments Commission, a review has found.

Independent reviewer KordaMentha Forensic examined how Commonwealth Financial Planning and Financial Wisdom dealt with clients of 15 problematic former advisers.

There were 2707 affected clients, but the dealer groups agreed to write to clients even when there was no evidence of them receiving financial advice.

This meant KordaMentha reviewed 4333 cases.

It found the dealer groups provided reasonable access to compliance experts to review cases.

They failed to meet a deadline for contacting clients in only two cases.

The report says the dealer groups helped the independent adviser examining the cases, and helped clients receive compensation when appropriate.

The bank has now paid $4.9 million to 185 clients of the advisers, in addition to $26.97 million paid to 707 customers of the same 15 advisers under a previous program.

“This report demonstrates the thorough approach we have taken to identify any past issues and put things right for customers,” Commonwealth Bank EGM Advice Review Program Leif Gamertsfelder said.

KordaMentha Forensic will continue to review advice given in 2012 and earlier by 17 potentially high-risk advisers.

A report on this investigation will be published next year.
