## Questions

### Who runs investment decisions at IHS?

Sir Chris Hohn is the founder, CEO, and sole portfolio manager of IHS. He makes all investment decisions personally, drawing on a tight team of analysts in London. Hohn was formerly a manager at Perry Capital before establishing IHS in 1993.

### What is the relationship between IHS and the Children's Investment Fund Foundation (CIFF)?

IHS is the family office and investment vehicle of Sir Chris Hohn. A portion of its returns flows to CIFF, the philanthropic foundation Hohn established with his former wife. CIFF has an endowment estimated at over $4.8B (per CIFF, 2024) and focuses on children's health, education, and climate issues. The two entities operate with shared governance but distinct legal structures.

### Does IHS accept external capital from other investors?

No. IHS operates as a single-family office and does not manage funds on behalf of external limited partners. All capital under management belongs to Sir Chris Hohn and his philanthropic entities. The firm was originally open to outside investors in its hedge fund structure but shifted to a closed family-office model.

### How does IHS's philanthropic mandate affect its investment decisions?

Hohn has said the long-term horizon of CIFF allows him to be patient with activist campaigns. The investment team does not rely on quarterly liquidity withdrawals, which reduces short-term pressure. However, the strategy remains return-driven; philanthropy is a use of proceeds, not a constraint on the portfolio.

### Which campaigns is IHS best known for?

The most famous campaign was targeting ABN AMRO in 2007, where IHS helped force the Dutch bank's auction to a consortium led by Royal Bank of Scotland (per Financial Times, 2007). Other notable engagements include positions in United Technologies, where Hohn pushed for restructuring, and Japan's NTT (per Reuters, 2018).

### Where is IHS headquartered, and does it have additional offices?

IHS is headquartered in London, United Kingdom. Public records show no additional offices; the firm operates from a single location in Mayfair. Hohn has stated a preference for a compact team based in one city.
