(1) For the purpose of determining the amount of any post-commencement supplement, a qualifying company is to be taken at all times in its post-commencement periods to have a continuing mixed pool (the “ring fence pool”) of—
(a) the carried forward qualifying Schedule 19B amount (if any),
(b) the company's ring fence losses, and
(c) post-commencement supplement.
(2) The ring fence pool continues even if the amount in it is nil.
(3) For the purpose of determining the amount of any post-commencement supplement, a qualifying company is also to be taken in its post-commencement periods to have a non-qualifying pool consisting of the carried forward non-qualifying Schedule 19B amount.
(4) But the non-qualifying pool ceases to exist when the amount in it is reduced to nil.
(5) In this section—
“the carried forward qualifying Schedule 19B amount”, in relation to a qualifying company, means the amount in its qualifying pool for the purposes of Part 4 of Schedule 19B to ICTA immediately before 1 January 2006, and
“the carried forward non-qualifying Schedule 19B amount”, in relation to a qualifying company, means the amount in its non-qualifying pool for the purposes of Part 4 of Schedule 19B to that Act immediately before 1 January 2006.
