693.2. In this Book, except Title VI.11, the following rules apply in respect of a taxpayer if one or more partnerships (each of which is in this section referred to as an “interposed partnership”) are interposed between the taxpayer and a given partnership, for a given fiscal period of the given partnership:(a) the taxpayer is deemed to be a member of a particular partnership at the end of a particular fiscal period of the particular partnership and that particular fiscal period is deemed to end in the taxpayer’s taxation year in which ends the fiscal period of the interposed partnership of which the taxpayer is directly a member, ifi. the particular fiscal period is that which ends in the fiscal period (in this section referred to as the “interposed fiscal period”) of the interposed partnership that is a member of the particular partnership at the end of that particular fiscal period, and
ii. the taxpayer is a member, or deemed to be a member under this subparagraph a, of the interposed partnership described in subparagraph i at the end of the interposed partnership’s interposed fiscal period; and
(b) the taxpayer’s share in an amount in respect of the given partnership for the given fiscal period is deemed to be equal to the proportion of that amount represented by the proportion obtained by multiplying the agreed proportion in respect of the taxpayer for the interposed fiscal period of the interposed partnership of which the taxpayer is directly a member, byi. if there is only one interposed partnership, the agreed proportion in respect of the interposed partnership for the given partnership’s given fiscal period, or
ii. if there is more than one interposed partnership, the result obtained by multiplying together all proportions each of which is the agreed proportion in respect of an interposed partnership for the particular fiscal period of the particular partnership referred to in subparagraph a of which the interposed partnership is a member at the end of that particular fiscal period.
If the first paragraph applies for the purpose of determining an amount that a corporation may deduct under Title V because of section 714, subparagraph b of that paragraph is to be read as follows:“(b) the proportion of the taxpayer’s share in the given partnership for the given fiscal period is deemed to be equal to the product obtained by multiplying the proportion of the taxpayer’s share in the interposed partnership of which the taxpayer is directly a member for the interposed partnership’s interposed fiscal period, by
i. if there is only one interposed partnership, the proportion of the interposed partnership’s share in the given partnership for the given fiscal period, or
ii. if there is more than one interposed partnership, the result obtained by multiplying together all proportions each of which is the proportion of an interposed partnership’s share in the particular partnership referred to in subparagraph a of which the interposed partnership is a member at the end of the particular partnership’s particular fiscal period for that particular fiscal period.”
