A more difficult question, however, is whether it is not true to say of the entire amount of each half-yearly distribution that as a whole, without any distinction being drawn amongst its ingredients, it should be put into the category of income as being the fruit of the carrying out of a plan or scheme, devised by the managers, carried out by the managers and the trustees in co-operation, and joined in by the certificate holders, for the purpose of yielding regular periodical returns to the certificate holders upon their invested capital. This was not exactly the view taken by the commissioner when he made the assessment; he was content to treat that portion of the distributed fund which came from dividends received by the trustees as the income of the certificate holders derived from property; and it was only that portion which came from the proceeds of sale of rights and from profits on realizations of investments that he took to be the certificate holders' income from personal exertion as having arisen from the carrying out of a profit-making scheme. In order to support one or other of these views, counsel for the commissioner devoted a great deal of attention to the history of the dealings in securities and rights which actually took place in the course of the administration of the trust. The evidence established that these dealings were considerable; they occurred frequently and produced substantial profits. Indeed, most sales of securities were made at prices in excess of cost. Moreover, all the profits thus made, less such losses as were sustained, were paid out to the certificate holders in the half-yearly distributions, the managers exercising the discretion given them by cl. 13 (B) to include all these profits (less losses) in the "cash produce". This was a course of action which obviously had been contemplated from the beginning; and if the proper conclusion from the evidence were that the managers and the trustees co-operated in pursuing a systematic course of buying and selling securities for the purpose of producing profits and thereby swelling the half-yearly amounts of "cash produce" available for distribution to certificate holders, the commissioner's opinion that such profits should be treated as assessable income of the certificate holders when paid over to them would be clearly correct. But the evidence of the only witness in the case, Mr. T. R. Groom the managing director of Unit Trusts Ltd. was that at no time were securities acquired for the express purpose of re-sale at a profit, and that sales were normally made when the managers anticipated a fall in the value of shares. The purpose (he explained in effect) was to preserve for the fund any increase in value which had occurred and which it seemed likely would otherwise be lost. He said (p. 115) that the general policy of the managers was to hold the securities as investments, and that their "standard idea" in buying was to buy the best available securities and to hold them unless there appeared to be some very good reason for selling. The factors they had before them in buying, he said (p. 114), were security, realizability, yield and possibility of capital appreciation, in that order. They had said something similar in a report for the half-year ended 15th December 1946: " it is not the policy of the managers to buy securities with a view to their resale at a profit " Now, Mr. Groom's evidence on these points was accepted by the Board of Review who saw him as a witness, and on this evidence the majority of the Board made findings which a member, Mr. Bock, expressed in these words (p. 14): "The over-riding consideration in the changing of investment was to ensure security of capital, which, in the manager's view, included not only the purchase cost to them but also any advance in the market price which may have taken place after the date of purchase. From the witness's evidence I think it must fairly be said that during the relevant period the managers kept themselves closely informed of market trends and wherever they were of the opinion that securities were likely to fall in market value, parcels of shares were sold to avoid a reduction in value of each unit in the trust which would be consequent upon a decline in market value of the shares held". We would not be justified in taking a different view, and the case therefore cannot be treated as one in which beneficiaries receive from trustees profits made by the sale of property acquired for the purpose of profit-making by sale.
