Suncorp Bank chief executive David Foster is to leave the bank after 10 years. The group's chief financial officer, John Nesbitt, will take over as head of the bank.Foster said, in a media release issued yesterday, that the completion of the non-core banking portfolio run-off was a "major milestone achievement", leaving the bank in a strong position and signalling it was a good time for a leadership transition.In 2009, in the midst of the financial crisis, Suncorp Bank put $18 billion of impaired commercial and property loans into a run-off portfolio.In June, Suncorp announced the sale of $1.6 billion of the remaining $2.8 billion of the portfolio to Goldman Sachs. The assets were sold at a "weighted realisation" of 60 cents in the dollar.At the time the Goldman Sachs sale was announced, Suncorp said it expected further run-offs and individual loan sales to reduce the remaining portfolio by $700 million this year.A balance of about $500 million has been absorbed back into the bank's overall lending portfolio.
