Frequently asked questions

Who runs investment decisions at the Alfred I. duPont Testamentary Trust?

The trust's investment portfolio is managed by the Alfred I. duPont Trust Company, a Florida-chartered trust company headquartered in Jacksonville. The board of trustees, chaired by Winfred L. Thornton, oversees both the charitable distribution and asset management functions. The trust company employs a professional investment staff that manages a diversified portfolio across public equities, fixed income, and alternative assets.

How is the trust related to Nemours Children's Health?

The trust is the sole member of the Nemours Foundation, which operates Nemours Children's Health. This structure means the trust controls the health system entirely — it is not merely a donor. Nemours generates its own operating revenue (over $1.9 billion in 2022), which funds hospital operations independently, while the trust maintains a separate investment portfolio for grantmaking and capital projects.

What is the trust's annual charitable distribution?

The trust is required by Alfred I. duPont's will to distribute all net income annually to the Nemours Foundation for the benefit of children's health — primarily in Florida, with a specific allocation for the Delaware hospital. The exact annual distribution fluctuates with investment returns and Nemours' capital needs; the November 2023 $100 million commitment to Nemours' digital transformation is an example of a major supplemental distribution beyond ordinary income.

Does the trust invest in anything beyond Nemours?

Yes. While Nemours is the dominant asset, the Alfred I. duPont Trust Company manages a diversified financial portfolio. The trust also holds real estate assets, including timberland in the Florida Panhandle. Historically, it controlled significant stakes in the Florida East Coast Railway (sold in 2017) and the Florida Times-Union newspaper, though media exposure has been reduced.

Where does the underlying wealth come from?

The wealth originates from Alfred I. duPont's inherited stake in E.I. du Pont de Nemours and Company, the Delaware-based chemical and explosives manufacturer. duPont also built his own manufacturing and banking interests in Florida after relocating there. His 1935 will left the bulk of his estate — roughly $40 million at the time — to the testamentary trust.

Is the trust structured as a foundation or a family office?

Neither — it is a testamentary charitable trust governed by the terms of Alfred duPont's will rather than IRS foundation rules. It functions more like a holding company with a charitable purpose. The trust does not manage family wealth for duPont descendants; all assets are irrevocably dedicated to the charitable mission, with the Nemours Foundation as the primary beneficiary.

What is the trust's geographic focus?

The will specifies that the trust's charitable efforts must primarily benefit Florida — hence the Nemours Children's Hospital in Orlando and extensive pediatric clinics throughout the state. A secondary, historically rooted commitment serves Delaware through the Nemours/Alfred I. duPont Hospital for Children in Wilmington, near the duPont family's ancestral home. The trust's timberland and real estate holdings are concentrated in North Florida.
