Sustainable investing gives investors a more complete view of an investment’s overall risk profile and return potential. It adds useful information that may not appear in traditional financial analysis alone.
All public entities in Illinois that have public funds within their custody are subject to this law. This law applies to all current operating funds, special funds, interest and sinking funds, and any other funds. What that means for you is that changes will need to be made to the investment policy statement to reflect that sustainability factors are being incorporated into investment decision-making related to funds in your custody. The investment policy should include material, relevant, and decision-useful sustainability factors to be considered in evaluating investment decisions. Sample policy language can be found on our website.
The implementation of this integration can vary based on how funds are managed. For instance, if an investment manager is used, you can ask questions during the manager selection process or after selection to better understand how the manager is accounting for these investment risks. We have sample Sustainability Due Diligence Questionnaires for Investment Manager Evaluation and Security Analysis Due Diligence available on our website for your reference.
