Briefs: CBA's CEO bonus targets defined, two directors retire from CBA board 21 September 2012 4:23PM Briefs, Ian Narev, CEO of Commonwealth Bank, will qualify for A$4.1 million in bonus shares. Narev will qualify for three quarters of the bonus if the bank's total shareholder return is in the top quartile of a peer group of more than a dozen (non-resource) companies listed in the top 20 on the ASX. The remaining quarter depends on the bank improving its customer satisfaction rating against rivals. Colin Galbraith and Fergus Ryan will leave the board of Commonwealth Bank next month after 12 years. The bank is yet to announce their replacements.
