The fund will now be part of AMP's corporate super business, SignatureSuper.
AMP's corporate super business will manage all aspects of the corporate super fund.
Previously, Russell had managed the fund's investments while Aon administered the fund.
The fund has over $400 million in funds under management (FUM).
In 2003, AMP established SignatureSuper, which is aimed at corporate funds with more than $20 million in FUM.
The business recorded an overall 14 per cent increase in membership in the 12 months to November, AMP Corporate Superannuation director Greg Healy said.
