In recent days, a joint Fairfax Media and Four Corners investigation has been building towards exposing a systemic and uncontrolled culture at CBA's insurance arm, CommInsure, where profits are put before the best interests of people both inside and outside the bank, and which has continued after CEO Ian Narev's promises to become an "ethical bank". As the investigation showed, CommInsure's lack of ethics extended even to its own employees. One staff member suffering depression and post-traumatic stress disorder was not afforded the support he'd expected.  The allegations made are of concern not least because CommInsure has more than 4 million policyholders and collects A$2.5 billion in premiums every year, placing it as one of the country's largest life insurers. The scandal also "escalates concerns about the culture inside the Commonwealth Bank, still trying to repair its reputation after a Senate inquiry recommended a royal commission into the bank's financial planning scandal," Fairfax Media observes. The Senate has now adopted a motion moved by Senator John Williams to broaden the terms of reference of a financial services inquiry  (the Scrutiny of Financial Advice inquiry) to include the $44 billion life insurance industry, Fairfax media reports. The latest allegations prompted CBA boss Ian Narev to release a statement over the weekend."Life insurance is there to support customers and their families at times of great need and distress. Insurance providers have a responsibility to deal with claims as sensitively, as quickly and as fairly as possible," the statement said.
