With the objective of providing transparency to our long-term expected returns, the documents below detail the methodologies underlying our models. A good place to start is with the methodology overview document, which provides background on the building block approach. This is the common framework that serves as the foundation on which each model is built. Each asset class then has its own methodology document detailing specifics related to that asset class. These are living documents that will evolve over time, and we encourage you to check back in the future for updates.
