CRSP Market Indexes Notification – Changes to Index Governance

Beginning July 1, 2026, governance of the CRSP Market Indexes will transition to the standard Morningstar Indexes Governance framework, replacing the governance authorities and procedures currently outlined in the CRSP Market Indexes Governance Committees Terms of Reference.

The index design review functions previously performed by the CRSP Index Management Committee will be assumed by the Morningstar Index Methodology Committee. Similarly, the functions of the CRSP Index Operating and Index Eligibility Committees will be covered by the Morningstar Index Operations Committee. The Morningstar Index Oversight Committee provides an additional layer of independent oversight across the Morningstar Indexes business, including CRSP indexes, in accordance with the IOSCO Principles for Financial Benchmarks and EU Benchmark Regulation, and as a result the CRSP Index Advisory Council will be dissolved.

This update will be reflected in a new version of the CRSP Market Indexes Methodology Guide, which will be published on July 1, 2026. No changes are being made to index construction or calculation methodologies as a result of this update.
