“(1) Subject to the following provisions of this Schedule, a chargeable gain accruing to any person on the disposal of any asset is a gain on the disposal of a business asset if that asset was a business asset throughout its relevant period of ownership. (2) Where— (a) a chargeable gain accrues to any person on the disposal of any asset, (b) that gain does not accrue on the disposal of an asset that was a business asset throughout its relevant period of ownership, and (c) that asset has been a business asset throughout one or more periods comprising part of its relevant period of ownership, a part of that gain shall be taken to be a gain on the disposal of a business asset and, in accordance with sub-paragraph (4) below, the remainder shall be taken to be a gain on the disposal of a non-business asset. (3) Subject to the following provisions of this Schedule, where sub-paragraph (2) above applies, the part of the chargeable gain accruing on the disposal of the asset that shall be taken to be a gain on the disposal of a business asset is the part of it that bears the same proportion to the whole of the gain as is borne to the whole of its relevant period of ownership by the aggregate of the periods which— (a) are comprised in its relevant period of ownership, and (b) are periods throughout which the asset is to be taken (after applying paragraphs 8 and 9 below) to have been a business asset. (4) So much of any chargeable gain accruing to any person on the disposal of any asset as is not a gain on the disposal of a business asset shall be taken to be a gain on the disposal of a non-business asset. (5) Where, by virtue of sub-paragraphs (2) to (4), above, a gain on the disposal of a business asset accrues on the same disposal as a gain on the disposal of a non-business asset— (a) the two gains shall be treated for the purposes of taper relief as separate gains accruing on separate disposals of separate assets; but (b) the periods after5th April 1998 for which each of the assets shall be taken to have been held at the time of their disposal shall be the same and shall be determined without reference to the length of the periods mentioned in sub-paragraph (3)(a) and (b) above.”
“Where any apportionment falls to be made for the purposes of this Schedule it shall be made— (a) on a just and reasonable basis; and (b) on the assumption that an amount falling to be apportioned by reference to any period arose or accrued at the same rate throughout the period over which it falls to be treated as having arisen or accrued.”
“It seems to me that the language of paragraph 3(3) does require an apportionment of the gain to be made to be made and gives an instruction as to how that apportionment is to be made. That provision states: “… the part of the chargeable gain accruing on the disposal of the asset that shall be taken to be a gain on the disposal of a business asset is that part of it that bears the same proportion to the whole of the gain as is borne to the whole of the relevant period of ownership….” (Emphasis added)
“It seems to me clear that paragraph 21(b) expressly envisages that the apportionment of an amount over the relevant period of ownership should be done on the basis that the gain accrued at the same rate throughout the period. Effectively, this reinforces the view that, when a gain must be apportioned over a period of time, a time apportionment method is the correct method to use. From this it also follows, in my view, that a time apportionment of the gain between the BATR period and the non-BATR period cannot be regarded as being unjust or unreasonable.”
“In my view, the statutory provisions in this case are clear and require time apportionment even though the greater part of the gain in this case arose from the growth in value during the BATR period.
“(4) For the purpose of calculating the amount of the supplementary charge on the company for the straddling period— (a) so much of that period as falls before24 March 2011 , and so much of that period as falls on or after that date, are treated as separate accounting periods, and (b) the company's adjusted ring fence profits for the straddling period are apportioned to the two separate accounting periods in proportion to the number of days in those periods. (5) But if the basis of apportionment in subsection (4)(b) would work unjustly or unreasonably in the company's case, the company may elect for its profits to be apportioned on another basis that is just and reasonable and specified in the election. (6) The amount of the supplementary charge on the company for the straddling period is the sum of the amounts of supplementary charge that would, in accordance with subsections (4) and (5), be chargeable on the company for those separate accounting periods.”
“I do not see…that the fact that time apportionment represented the default position says anything important about when a company could elect for a different basis of apportionment. At most, it might be inferred that something of more than minimal significance was needed to justify departure from time apportionment.”
“I do not think the application of section 7(4) could be said to work "unjustly or unreasonably" unless time apportionment would prejudice the company in question to a more than minimal extent. It seems to me, however, that any company which earned profits at a significantly faster rate in the Earlier Period than the Later Period, and so stands to be materially prejudiced by time apportionment, can avail itself of section 7(5). It matters not, in my view, whether the differential profitability arose from the exceptional or the routine. The FTT thought that section 7(5) applies to all companies "whose profits are not smoothly spread throughout the year, but whose profits differ greatly from one part of the year to the other, and who could be disadvantaged by … a change of tax rate part way through an accounting period". I agree.”
