Macquarie Group has upgraded its earnings guidance thanks to an increased contribution from Macquarie Funds. The group expects its results for the 12 months to March 2015 to be "slightly up" on the A$1.3 billion it earned in 2013/14.In its previous guidance, in July, Macquarie said the funds division would produce a net profit contribution in 2014/15 that was broadly in line with the 2013/14 result.The division's assets under management fell by 4.6 per cent to A$405 billion during the June quarter. This was related to a transfer of assets following an acquisition in the US.The outlook now is for Macquarie Funds' results to be up on the 2013/14 result.In a presentation to be delivered at an investor forum on Hong Kong this week, Macquarie chief financial officer Patrick Upfold said the outlook for the group's five other divisions was unchanged.
