## Questions

### What is the source of the wealth managed by Samjo Management?

The underlying wealth originates from Samuel J. Heyman's control and transformation of GAF Corporation into International Specialty Products (ISP), a pure-play specialty chemicals company. The fortune was substantially monetized through the $3.2 billion all-cash sale of ISP to Ashland Inc. in 2011. Heyman was a prominent corporate raider and investor in the 1980s, patterning his career after successful proxy-fight activists of the era.

### Does Samjo Management participate in fund commitments or only direct deals?

Samjo Management uses a hybrid approach, allocating to external fund managers for specialized access while maintaining a separate book of direct investments. Direct activity has historically focused on public equities and real estate assets, particularly in the New York and Northeast regions. The office does not publicly disclose its asset allocation split between funds and direct investments.
