Analytics & Insights

Gleaning financially material information from companies requires expert capabilities, trusting partnerships, and robust data sets. From climate to governance structures, our commitment to rigorous analysis helps investors gain insights they need to make informed decisions.


Our proprietary ESG scoring system draws on data from multiple providers, the Sustainability Accounting Standards Board (SASB)’s widely accepted, transparent materiality framework and relevant corporate governance codes to generate a unique ESG score for approximately 10,000 issuers.

Why We Built R-Factor™

Quality data about companies’ ESG practices is critical for effective investment analysis, but the lack of standardization and transparency in ESG reporting and scoring presents major challenges for investors.

Defining Characteristics of R-Factor™

We designed R-Factor™ around four core pillars:

Supporting Sustainable Capital Markets

R-Factor™ supports the development of sustainable capital markets by helping investors identify ESG solutions that integrate financially material ESG data while incentivizing companies to improve their ESG practices and disclosure in areas that matter.
