rr_StrategyNarrativeTextBlock

Clearwater Management Company (“CMC”) serves as the investment manager to the Fund and is responsible for the oversight of the Fund’s subadvisers. The allocation among subadvisers will vary over time, but the current intent of the Fund’s adviser is that under normal market conditions approximately 60% of the Fund’s total assets will be allocated to Parametric and the remaining assets will be allocated to one or more of the Fund’s two other subadvisers that provide day-to-day management.
