Morningstar Information

Morningstar RatingTM   As of Dec 31, 2021
Period Stars Category Size
Overall 3 Stars557
3-Year 3 Stars557
5-Year 3 Stars478
10-Year 3 Stars315

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 10–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% 10–year rating/30% five–year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods.
