Mission-Related Investment

Private foundations hold endowments — pools of invested assets whose returns fund grantmaking over time. Traditionally, foundations kept their endowment investments entirely separate from their charitable purpose, optimizing purely for financial return. MRIs challenge that separation by asking whether some portion of the endowment can do double duty: earning competitive returns while also supporting the mission. A foundation focused on affordable housing, for example, might hold mortgage-backed securities tied to low-income housing development as part of its fixed-income allocation.

The MRI concept is distinct from a program-related investment (PRI). An MRI is evaluated primarily as an investment and must meet the same financial return expectations as comparable assets in the portfolio. It lives in the endowment. A PRI, by contrast, is classified as a charitable distribution and is made primarily for programmatic impact, with financial return as secondary. Foundations and their legal counsel must track this distinction carefully because the two carry different regulatory treatment.

Families building a philanthropic program through their family office often find MRIs useful when their impact investing goals and foundation mission overlap. Consider a family foundation whose mission is advancing health equity: it might hold equity in community health clinics through a private fund structured to deliver both mission impact and a return, classifying that position as an MRI within the endowment's asset allocation.

Because MRIs involve fiduciary obligations, tax considerations, and regulatory definitions that vary by jurisdiction and evolve over time, families must work with qualified attorneys and CPAs before implementing them. The governance process — including how the investment committee evaluates MRI candidates — should be documented in the foundation's investment policy statement.
