Paragraph 4 Determination of aggregate non-core spending obligation
Before determining the amount of the aggregate non-core spending obligation for scheme year 2, 3 or 4, (“year t”), the Secretary of State must—
(a)
review the core group spending estimate for year t-1; and
(b)
increase or reduce that estimate, if it appears to the Secretary of State that the aggregate amount of benefits provided under Part 3 in year t-1 will be greater or less than the estimate.
