“ …in my view, s 152(3) [now section 273(3)] is effective to provide that any information, including unpublished confidential information, and even information which might prejudice the interests of the company, is assumed to be available in the hypothetical sale if it would be reasonably required by a prudent prospective purchaser of the asset in question. It is therefore necessary to consider, in each case, what information a prudent prospective purchaser of the asset in question would reasonably require. In the context of s 152(3) I understand the word 'require' to mean 'demand as a condition of buying'; information is 'required' if the purchase would not proceed without it.” 205. The question of what a prudent purchaser would reasonably require is essentially a value judgment, informed by the expert evidence. In Caton’s Administrators, Dr Brice also had regard to an observation in Dymond’s Capital Taxes. At page 51a Dr Brice stated as follows: “ Dymond, para 23.328 also says that where the holding is less than 25% it may be that the buyer will expect less information but this is a matter for expert evidence. The size of the company is important and a buyer investing£200,000 would obviously be entitled to know more than one investing£2,000 . Where the holding was small, say less than£50,000 and less than 5% of the capital, the buyer would not normally be expected to have more than the information which was published or which he could find out without questioning the directors.”
