## Questions

### Who runs investment decisions at Iscar?

The Wertheimer family allocates its capital through a corporate-investor structure tied to the IMC Group, with CEO Jacob Harpaz — a company veteran who worked alongside founder Stef Wertheimer for decades — overseeing operations. No dedicated family-office investment committee is publicly identified. The family's posture is hands-on industrial ownership rather than third-party fund management.

### How is Iscar related to Berkshire Hathaway?

Berkshire Hathaway acquired 80% of the IMC Group from the Wertheimer family in 2006 for $4 billion and purchased the remaining 20% in 2013 for $2.05 billion. Iscar now operates as a wholly owned Berkshire subsidiary. The Wertheimer family's investment capital is managed separately from Iscar's corporate balance sheet, though the family maintains influence through long-standing operational relationships.

### What investment structures does Iscar use — direct, fund commitments, or both?

Iscar invests directly, not through fund commitments. Its known deployment vehicles are joint ventures with industrial partners — Blades Technology Ltd. with Pratt & Whitney and Techjet Aerofoils with Rolls-Royce — and direct ownership of industrial parks and real estate. There is no public evidence of the family acting as a limited partner in third-party funds.

### Which sectors does Iscar explicitly avoid?

The firm has shown no appetite for financial services, enterprise software, consumer internet, or life sciences. Its observable portfolio is confined to precision manufacturing, aerospace components, industrial real estate, and economic-development infrastructure in Israel and Turkey — a narrow, hard-asset mandate with no disclosed diversification into intangible-asset sectors.
