## About

The Williams International Pension Plan for Employees was established in 1969 as a noncontributory defined-benefit plan covering eligible employees of Williams International, the Pontiac, Michigan-based manufacturer of small gas-turbine engines for business jets and cruise missiles. Founder Sam Williams built the company into a critical defense supplier; since his death in 2009, his son Gregg Williams has led both the operating business and its affiliated pension trust. The plan provides retirement, disability, and death benefits while maintaining an investment strategy that reflects the engineering rigor of the industrial enterprise it serves. The plan pursues a multi-asset strategy spanning venture capital, buyout, growth equity, mezzanine, and secondaries, with exposure through both direct investments and fund-of-funds commitments. Stage coverage runs from seed and early-stage to expansion-stage and late-stage vehicles. The geographic focus remains concentrated in North America, consistent with the manufacturing footprint that includes facilities in Michigan, Utah, Florida, and Alabama. The plan shares governance proximity with Williams International's 401(k) vehicle and the Sam Williams Foundation, the family's philanthropic arm. Gregg Williams serves as trustee of the foundation and maintains active membership in industry associations including the General Aviation Manufacturers Association board and the Living Legends of Aviation. Structurally, the plan blurs the line between corporate pension and de facto family-investment vehicle. With a single-family-controlled sponsor, no external LP reporting obligations, and a founder legacy still embedded in governance, the fund enjoys an independence of mandate that most corporate plans cede to consultants. Succession of both the operating company and the pension trust now rests with the second generation — a concentrated governance model that preserves decision velocity but concentrates key-person risk.

## Questions

### Is the plan open to co-investment alongside external general partners?

The plan's strategy includes direct early-stage and expansion-stage investments, which structurally accommodates co-investment alongside GPs. However, because the plan does not publicly disclose specific fund relationships or co-investment vehicles, external managers should not assume an open-door co-investment posture without direct inquiry to the Pontiac office.

### How is the pension plan related to the Sam Williams Foundation?

Both entities share governance through Gregg Williams, who controls the operating company, oversees the pension trust, and serves as trustee of the Sam Williams Foundation. The foundation represents the family's philanthropic arm. There is no public evidence of commingled assets between the two, though the shared governance means allocation philosophy and key-person risk are concentrated across the entire Williams entity structure.
