877Election for fixed-rate writing down in relation to resulting assetU.K.
(1)This section applies if—

(b)no election under section 730 (writing down at fixed rate: election for fixed-rate basis) has been or is subsequently made in respect of the original undivided asset.
(2)An election under that section may be made in respect of any of the resulting assets.
(3)But such an election may be made only within the period during which such an election could have been made in relation to the original undivided asset.

(c)the appropriate proportion of every amount falling to be taken into account in relation to the original undivided asset is attributed to each of the notional original assets, and
(d)this Part applies in relation to each of the notional original assets and its corresponding resulting asset accordingly.
(5)For the purposes of subsection (4)(c) the appropriate proportion of every amount falling to be taken into account in relation to the original undivided asset that is to be attributed to each notional original asset is found by reference to the notional original asset's corresponding resulting asset.
(6)The appropriate proportion in relation to each resulting asset is—
where—
AVL is the accounting value of that resulting asset at the beginning of the later period, and
