The big industry fund AustralianSuper has announced a merger with public sector fund AGEST Super.
The merger will take place in 2012 after the funds conduct due diligence, and will bring AustralianSuper's total funds under management to $46 billion.
AustralianSuper chief executive Ian Silk said the union of the two funds would provide greater benefits for AGEST members and maximise their retirement savings.
"We aim to keep growing as scale enables us to deliver the best prospects for secure retirement to the greatest possible number of Australian workers," Silk said.
AGEST has 130,000 members and $4.3 billion in assets.
This is the second merger announcement for AustralianSuper in 2011, with Westscheme merging into the fund in June.
The two funds have announced the signing of a non-binding MOU to explore a potential merger.
The board must shift its focus from managing inflation to stimulating the economy with the trimmed mean inflation figure edging closer to the 2.5 per cent target, economists have said.
ASIC chair Joe Longo says superannuation trustees must do more to protect members from misconduct and high-risk schemes.
Super fund mergers are rising, but poor planning during successor fund transfers has left members and employers exposed to serious risks.
