Industry super fund REI Super has retained Ibbotson Associates to its investment consulting mandate for another three years.
It comes after a thorough due diligence process, which was assisted by SuperRatings.
Chief executive of REI Super Mal Smith said Ibbotson and the super fund have had a relationship for more than a decade.
During this time, Ibbotson helped the fund create the Premium Income option, which is a low-volatility investment option for those entering retirement or who are over 55 years.
The Morningstar Investment Management group, to which Ibbotson belongs, had around US$169 billion in assets under advisement and management at 30 September 2014.
