ESG Integration

ESG Integration

ESG integration is the practice of incorporating material environmental, social and governance (ESG) information or insights alongside traditional measures into the investment decision process to improve long term financial outcomes of portfolios. Unless otherwise stated in Fund documentation or included within the Fund’s investment objective, inclusion of this statement does not imply that the Fund has an ESG-aligned investment objective, but rather describes how ESG information is considered as part of the overall investment process.


The Fund manager considers ESG information in the research, security selection and portfolio review stages of the investment process. The Fund manager conducts bi-weekly credit meetings, wherein each credit is examined through an internal relative value analysis, which contains qualitative governance considerations combined with environmental, societal and governance metrics derived from third-party data providers. The Fund manager conducts regular portfolio risk reviews with Risk and Quantitative Analysis group. These reviews include discussion of the portfolio’s exposure to material ESG risks.
