The pending US$4.6 billion acquisition of GE Capital Finance Australasia by an investor group including KKR & Co. and Deutsche Bank AG is the second-largest cross-border deal.

Macquarie Bank, AustralianSuper and Slater & Gordon also feature in the top five outbound Australian deals.
Macquarie Group has also been the biggest beneficiary of Australian M&A fees, capturing 20 per cent of the market.
UBS and Goldman Sachs rank second and third, respectively, when it comes to M&A fees in 2015, said Thomson Reuters.
