Lloyds Banking Group has put most of its troubled loans in Australia behind it.The UK-based bank said that its impaired loans in Australia decreased by £56 million, to £39 million, at December 2012, compared with £95 million at December 2011.Impaired loans as a percentage of gross loans decreased to 1.0 per cent, from 2.3 per cent, over 2012. The impairment charge in Australia more than halved to £15 million, helped by the sale of many problem loans. It put its "non-core Australian corporate" loan book at £2.3 billion. Commercial real estate loans are now immaterial at around £100 million.Lloyds no longer breaks out any data on its earnings in Australia.One bright spot is its asset finance business, Capital Finance, which Lloyds said achieved new business growth, of 16 per cent, in 2012, and "continues to benefit from strong credit management and improving credit quality supported by a resilient Australian economy."      Lloyds said it "restricted new origination in Australia to [only] key clients with strong UK linkage."
