Paragraph 7 Determination of aggregate non-core spending obligation
Before determining the amount of the obligation for scheme year 3 or 4 (“year t”), the Secretary of State must (in addition to the steps in paragraph 4 to 6) calculate the difference between—
(a)
the aggregate amount of benefits provided under Part 3 in year t-2 (“At-2”); and
(b)
the core group spending estimate (with any increase or reduction previously made to it) for year t-2 (“Et-2”).
