The Australian reports that Westpac and Commonwealth Bank are offering higher commissions to win more business from mortgage brokers. Both banks have been losing share in the mortgage market for some time. CBA-owned Bankwest has raised upfront commissions from 50 to 70 basis points (although this is partly offset by a reduction in the first-year trailing commission). Westpac is offering an extra 10 basis points of upfront commission until the end of its financial year, September 30.Five former directors of Trio Capital have given undertakings that they will not work in the superannuation industry for periods of up to 12 years. The Australian Prudential Regulation Authority announced yesterday that Cameron Anderson, Michael Anderson, Terrence Hallinan, Lorenzo Macolino and John Harte had given enforceable undertakings. All five have acknowledged APRA's concern that they failed to carry out their duties properly as directors of a superannuation trustee. Trio board members did not adequately conduct due diligence in connection with the appointment of related-party investment managers.
