[I]t can be considered to be an established fact that UBCs share of the relevant market is always more than 40 per cent and nearly 45 per cent. This percentage does not however permit the conclusion that UBC automatically controls the market. It must be determined having regard to the strength and number of the competitors. It is necessary first of all to establish that on the whole of the relevant market the said percentage represents grosso mondo a share several times greater than that of its competitor Castle and Cooke which is the best placed of all the competitors, the other coming far behind. This fact together with the others to which attention has already been drawn may be regarded as a factor which affords evidence of UBCs preponderant strength.
