The first question therefore is whether their assent to that scheme, either alone or in combination with their ultimate compliance with the request made by the scheme trustee that Mr. Macpherson should transfer the whole of his shares and that Mrs. Macpherson should transfer 20 per cent of her shares (making a total of 60 per cent of the issued shares), constituted a "contract, agreement or arrangement" falling within s. 80B (5). It will be seen from the terms of cl. 27 that the scheme trustee could, if he chose, call upon Mrs. Macpherson to transfer the whole of her shares or only part thereof, although it is clear that if he exercised his right to the extent of 60 per cent of the total number of each category of shares he would have to call upon each of the two shareholders to transfer some shares, since each held 50 per cent of each category. It is clear that the scheme of arrangement gave the trustee the right to nominate the number of shares to be transferred by each of the two shareholders. I agree with the conclusion expressed in the judgment of Jacobs J. that the arrangement between the trustee and Mr. and Mrs. Macpherson, approving the scheme of arrangement constituted an "agreement or arrangement" and that such agreement or arrangement "while it remained executory conditionally affected the beneficial interest of Mrs. Macpherson in all her shares as well as the beneficial interest of Mr. Macpherson in all his shares. However it did so only at the time of its making and while it remained executory". During the period when it was executory (i.e. from 28th February 1967, when the scheme became operative, until 15th March 1967 when the transfers were signed, approved by the directors and registered), it affected the whole of the shares held by her (including those which she in fact retained in the year of income). It was however an agreement or arrangement such that, upon the power being exercised by the trustee to the full extent, i.e. exercised in respect of some part of the shareholding of each of Mr. and Mrs. Macpherson to a total extent of 60 per cent of the shares, the power was incapable of further exercise. The agreement or arrangement thereafter ceased to have any effect or operation upon the remaining shareholding of Mrs. Macpherson and could not affect Mr. Macpherson's shares for he no longer held any. The agreement or arrangement was therefore wholly spent. It did not thereafter relate to, affect, or depend for its operation upon any of the matters referred to in pars (i) to (iv) of s. 80B (5) (b). Thus the shares which Mrs. Macpherson held beneficially during the year of loss and had also held beneficially during the year of income were, at the time of the transfer of the balance of her shares in 1967, no longer conditionally or at all subject to or affected by the agreement or arrangement. No other arrangement was made by Mrs. Macpherson which related to, affected or depended for its operation upon any of the matters referred to in pars (i) to (iv) in accordance with the finding of the Board of Review and the trial judge.
