For corporates (financial and non financial), we use the same analysis scheme that we have built for equities assessment. Our philosophy is to have a single ESG score for each company whether it issues equity or debt.
On the other side, we have an ESG analysis scheme dedicated to sovereigns. For this purpose, we collect data from the World Bank, OECD, NGO (Transparency International, Reporters without borders...). This analysis is in-house realized, we don't use any provider or external consulting company to provide us rating or data.
