Impax Sustainable Allocation Fund

The Morningstar Rating for funds, or “star rating,” is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product’s monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five- and ten-year (if applicable) Morningstar Rating metrics. The weights are 100% three-year rating for 36-59 months of total returns, 60% five-year rating, 40% three-year rating for 60-119 months of total returns, and 50% ten-year rating, 30% five-year rating, 20% three-year rating for 120 or more months of total returns. While the ten-year overall rating formula seems to give the most weight to the ten-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods.

Morningstar Percentile Rank is a standardized way of ranking items within a peer group, in this case, funds with the same Morningstar Category. The observation with the largest numerical value is ranked one; the observation with the smallest numerical value is ranked 100. The remaining observations are placed equal distance from one another on the rating scale. Note that lower percentile ranks are generally more favorable for returns (high returns), while higher percentile ranks are generally more favorable for risk measures (low risk).
