We informed clients about an important update where Morningstar will rename the Morningstar Sustainability Rating for Funds to the Morningstar ESG Risk Rating for Funds.

This change aims to better align the name with the ratings' intended meaning and provide consistency with the naming conventions used by Morningstar and Sustainalytics at the issuer level.

On May 7, 2025, at 8:00 p.m. CDT, Morningstar Fund API Center will update the data point name within feeds and the ESG Fund Ratings API. Please note that the data point definitions will also be updated to reflect their new names.

Client Action:

For clients receiving the rating data through feeds: Clients need to act on this update, as the name change will not flow automatically to the feed header. Clients must update the header's name by editing the feed configuration in the Fund API Center platform to ensure they reflect the updated data point names.
For clients receiving the rating data through APIs: Clients need to update their processes to ingest the updated names to ensure no disruption. Review the attached technical spec for additional details about the name change.
User Acceptance Testing: Fund API Center will deploy this update to the user acceptance testing (UAT) environment on Apr. 14 at 8:00 p.m. CDT.

Please note that the rating's methodology and calculation will not be modified at this time; it will remain a risk-based measure, and the globe iconography associated with it will remain the same.

This update ensures that our ratings provide a more transparent, more accurate representation of the relative ESG risks associated with investment portfolios, empowering investors to make well-informed decisions.

We appreciate your understanding and support as we implement these enhancements, reinforcing our commitment to delivering high-quality, transparent investment information.
