MacArthur Foundation seeks to achieve strong, risk-adjusted net investment returns over time, at a cost comparable to other institutions with similar asset allocations. They use two methods for the ongoing management of its investment assets: an investment portfolio designed to earn a financial return sufficient to support a substantial, stable level of grantmaking and related operating activity over the planning horizon; and an impact investments portfolio dedicated to the advancement of the Foundation's program and philanthropic purposes. The Foundation maintains a broadly diversified portfolio with allocation to a variety of asset classes, both public and private, largely through investments in multi-investor pooled funds managed by outside investment managers that invest in underlying companies or securities. They manage risk through rigorous analytical research and broad diversification.
