Screening doesn't differ too much between internally managed equity and fixed income asset classes. We screen corporate issuers for both exclusion strategy that covers all internal investments and do norms-based screening. Latter is based on external service provider's analysis and classification, whereas the former is based on our internal exclusion list. However, majority of the items on the exclusion list are on the list because of the business involvement screening done by the ESG research provider. In SSA category, we run internal screening that ranks lowest scoring countries off from the investment universe.The scoring incorporates factors that relate to countries' social issues, among other things. Agencies and supranationals are subject to norm based screening.
