The Board of Trustees, through its Committee on Investments and investment staff, oversee, review and implement investment policies and guidelines. They are guided by two objectives: to support program initiatives and beneficiaries and to preserve the value of The Duke Endowment portfolio.

In 1924, our founder James B. Duke made an initial gift of $40 million. A bequest of $67 million was added to the Trust after his death in 1925. Since then, the assets of The Duke Endowment have achieved significant growth, from $107 million to $5 billion. During the same time, approximately $4.5 billion has been distributed in grants.

During 2022, the investment return on the Endowment’s portfolio was ‑5.3 percent.* Investment performance was driven by declines in public equities, fixed income and venture capital. 

The Endowment’s investment portfolio decreased in value from $5.8 billion to $4.9 billion from December 31, 2021, to December 31, 2022, impacted by investment returns, grants and expenses. The Endowment’s total assets were $5.0 billion at year end. 

For the 10-year period ending December 31, 2022, the Endowment’s investment portfolio, net of fees, returned 11.1 percent annualized, outperforming its policy benchmark, which returned 5.2 percent annualized, and a 70 percent MSCI All Country World Index/​30 percent Bloomberg Barclays U.S. Aggregate Bond Index benchmark, which returned 6.1 percent annualized over the same period.
