Past performance is not indicative of future results. Overall Morningstar Ratings are based on Risk-Adjusted Return.
The Morningstar Rating™ for funds, or “star rating,” is calculated for managed products 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 five stars, the next 22.5% receive four stars, the next 35% receive three stars, the next 22.5% receive two stars, and the bottom 10% receive one star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three- and five-year 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.
The Morningstar Sustainability Rating is a measure of the financially material environmental, social and governance, or ESG, risks in a portfolio relative to a portfolio's peer group.
The Morningstar Sustainability Rating is calculated through a three-step process.
First, Morningstar calculates the Morningstar Portfolio Sustainability Score for every portfolio reported within the trailing 12 months. This score is a historical holdings-based calculation using the company-level ESG Risk Rating from Sustainalytics, a leading provider of ESG research. The Sustainalytics’ company-level ESG Risk Rating measures the degree to which a company’s economic value may be at risk driven by ESG issues. To be considered material to the risk rating, an ESG issue must have a potentially substantial impact on the economic value of a company and therefore on the risk-return profile of an investment in the company. The ESG issues that are material vary across industry groups and companies.
Second, Morningstar uses these scores to calculate a portfolio's Morningstar Historical Portfolio Sustainability Score.
Third, Morningstar assigns a Morningstar Sustainability Rating for a portfolio based on its Morningstar Historical Portfolio Sustainability Score relative to its Morningstar Global Category.
Additionally, Morningstar applies ratings buffers to increase the rating's stability and makes ratings adjustments for portfolios with extreme Morningstar Historical Portfolio Sustainability Scores.
For each product category, 5 globes are assigned to the top 10%, 4 globes to the next 22.5%, 3 globes to the next 35%,2 globes to the next 22.5%, and 1 globe to the bottom 10%.
