Should I put all my hard-earned super into a single pension fund, or are there benefits from splitting it between 2 or 3 separate managers? Over the years I've built up a healthy balance in my super fund (accumulation phase). When I retire the lazy option is just to roll from the accumulation account into a corresponding pension account. Even if I'm happy with my current fund is that a smart thing to do? Splitting it up will almost certainly increase the cost. But is there a "risk" discussion to be had? With luck a pension might have to run 30 years or so and a lot can happen in 30 years. In theory the value of the fund is in the underlying assets and the manager is just a "middle-man". But a fund manager in trouble might make accessing the assets messy. What is regarded as good practice in this area ?
