Methodology Versioning

Methodology Updates and Versions

• Each rating report and fact sheet explicitly states the methodology version under which it was produced.

• When we update the methodology (e.g., weights, questions, mapping to ratings), we:

  • Publish a methodology update note

  • Explain the expected impact on existing ratings

  • Apply the new version to each subsequent rating

This ensures that ratings remain comparable over time while the framework evolves with the market.
