The arm-wrestling between ASIC and ANZ - and Australia's big banks generally - over poor culture and non-compliance continued yesterday, when ANZ confirmed it had engaged PricewaterhouseCoopers back in January 2016 to conduct an independent compliance review within its OnePath subsidiaries.This was necessary in the light of a series of events described by the bank as "compliance breaches that were proactively reported to the Australian Securities and Investments Commission from early 2013."For its part, ASIC said it sought the review "following a significant number of breaches reported by the ANZ Group in relation to its life and general insurance, superannuation, and funds management activities." "These activities are operated through [ANZ's] wholly-owned OnePath group of subsidiary companies."ANZ disclosed, via a media statement, that since February 2013 it has paid out compensation to the tune of approximately A$4.5 million, via payments made to around 1.3 million OnePath customers. In addition, as ASIC helpfully pointed out, the bank has faced costs for "rectifications and other remediation of approximately $49 million."In this instance, ANZ cast its net far and wide as breaches included not following up on unbanked cheques and superannuation contributions that were not being allocated to the customer's correct account. None of the breaches relate to life insurance claims, the bank insisted via a media statement yesterday. Examples of breaches included: Superannuation fund members had $28.7 million in contributions allocated to incorrect super accounts for periods of up to 12 months. ANZ has now returned these funds to the correct accounts and provided over $400,000 compensation for lost earnings and/or incorrect fees. OnePath failed to take further action in relation to 21,000 cheques sent to customers but not banked within 15 months. These cheques included proceeds of insurance claims, superannuation benefits and refunds of premiums. $2.9 million was ultimately returned to customers with a further $11.6 million treated as unclaimed monies.ASIC Deputy Chair Peter Kell said: "Appropriate compliance and systems to monitor compliance are essential for banks to adhere to their AFS obligations. This is important in maintaining customer trust and confidence in the sector."ASIC acknowledged the co-operation it had been given from ANZ.
