CTM18590 - Shadow ACT: computation of: distributions outside an accounting period
Where a distribution is made outside an accounting period (AP) it is treated as made in an AP matching that of the company's immediate parent in which the distribution falls, except that the period is shortened to exclude any part included in a true AP of the distributing company. Where the distribution does not fall in an AP of the immediate parent, its immediate parent is taken and so on until an accounting period in which the distribution can be treated as falling is found.
