# Methodology & Decision Framework

Every product operates within a defined decision framework.

Depending on the product, this may include:

* Fully rules-based methodologies (e.g. index strategies)
* Actively managed strategies with defined mandates and constraints
* High-level methodology disclosures for alpha-oriented products, where full transparency could compromise competitive advantage

Regardless of disclosure depth, all products operate within predefined and documented boundaries.

Material changes to a product’s methodology are communicated prospectively.
