“The hallmark requires one to envisage a hypothetical promoter of an arrangementwhich is the same or substantially similar to the arrangement in question and thento ask oneself whether it would be reasonable to expect that such a promoterwould be able to obtain a premium fee. It is, therefore, an objective test applied toa hypothetical promoter. The test does not require an examination of the subjectivecondition of the promoter. The fact that UKCO does not receive a premium fee isneither here nor there. It is equally irrelevant that it would be unreasonable toexpect that UKCO as promoter would be in a position to obtain a premium fee forthe services that it provided. Both considerations go to the subjective condition ofUKCO and are, accordingly, irrelevant.”
