In the United Kingdom the revaluation was carried out by Gerald Eve, Chartered Surveyors, Fuller Peiser, Chartered Surveyors and Storey Sons & Parker, Chartered Surveyors, in accordance with the appraisal and valuation manual of the Royal Institution of Chartered Surveyors. Overseas properties were valued principally by independent local valuers. |
