Suncorp Bank (Suncorp) upsized its Apollo Series 2012-1 residential mortgage-backed securities (RMBS) issue to A$1 billion (US$1.03 billion) from A$750 million based on an oversubscribed order book following launch on August 27. The deal's arranger says it attracted significant support from fund managers, while a bid from the Australian Office of Financial Management (AOFM) was scaled out almost completely.
