Most foundations have a charter aimed at improving the state of the world in which we live. The single most important resource to achieve this goal is through financial donations, or the income generated from endowments. The reputation risk of endowments being associated with speculative or unethical business practices, or investments that are in contrast with a foundation’s objective, has increasingly been an agenda item of foundation boards. In this project the PRIME Toolkit has been developed to help foundations manage their endowments in a socially responsible way.
