NAV per share at 30 Jun 2010

Caledonia Investments plc ("Caledonia") announces that its unaudited diluted net asset value ("NAV") per share as at 30 June 2010, calculated on a cum-income basis, was 1854p.

Due to the significant decline in the FTSE All-Share index since Caledonia’s latest review of unquoted investment valuations at 31 March 2010, net assets were reduced by £47.8m. This adjustment was calculated by applying the 12.6% decline in the FTSE All-Share index between 31 March and 30 June 2010 to the aggregate valuation of unquoted investments for which market prices were not readily available.

The monthly reported NAV per share, together with performance statistics and information on the valuation of principal investments, is available on Caledonia’s website at www.caledonia.com.
