Speaking at CBA's 2017 annual general meeting - his last as CEO - Ian Narev opted for a nostalgic and folksy tone - noting that the majority of the audience was retail investors.Narev had said this of another similar group of retail investors: "They were representative of the almost 800,000 retail shareholders who directly own more than half of your bank, and whose investment in CBA is collectively worth approximately $70 billion. When combined with Australian families who own CBA shares through their super or investment funds, the value of Australians' holdings rises to over $110 billion."For those in the room who had bought the minimum holding of CBA shares at the time of the 1991 float - 400 shares - and reinvested dividends every year since, their initial investment of $2,160 is now worth around $142,000, or around $162,000 including franking credits, Narev announced.Then, Narev was obliged to reel off a long list of failings under his watch, while looking to set a positive tone for his successor. "Beyond the obvious challenges, the 2018 financial year has already been a time of ongoing value creation," he said.Also up ahead is the sale of CBA's life insurance operations in Australia and New Zealand: the largest transaction in Australian financial services since 2010. Andrew Mohl, who has been a director since 2008, and would also have retired this week, in line with tenure guidelines, has agreed to serve a further year, as the Bank implements the transition of its life insurance business. This sale should be completed within the 2018 calendar year.Mohl will serve one more year on the Board and will retire at next year's AGM.
