8(1)The modification referred to in paragraph 6(3)(b) above is that, in determining whether the condition in paragraph 1(1)(b)(ii) above is fulfilled with respect to the account period of the primary fund referred to in paragraph 6(1) above, the United Kingdom equivalent profits of the primary fund for that period shall be treated as increased by the primary fund’s share of the excess income (if any) of the qualifying fund which is attributable to that period.
(2)For the purposes of this paragraph, the excess income of the qualifying fund for any account period of that fund is the amount (if any) by which its United Kingdom equivalent profits for that account period exceed the amount of the distributions made for that period, as determined for the purposes of the application of paragraph 1(1) above to the qualifying fund.
(3)If an account period of the qualifying fund coincides with an account period of the primary fund, then the excess income (if any) of the qualifying fund for that period is the excess income which is attributable to that period of the primary fund.
(4)In a case where sub-paragraph (3) above does not apply, the excess income of the qualifying fund which is attributable to an account period of the primary fund is the appropriate fraction of the excess income (if any) of the qualifying fund for any of its account periods which comprises the whole or any part of the account period of the primary fund and, if there is more than one such account period of the qualifying fund, the aggregate of the excess income (if any) of each of them.
(5)For the purposes of sub-paragraph (4) above, the appropriate fraction is—
where—
A is the number of days in the account period of the primary fund which are also days in an account period of the qualifying fund; and
B is the number of days in that account period of the qualifying fund or, as the case may be, in each of those account periods of that fund which comprises the whole or any part of the account period of the primary fund.
