A 'new scheme' is defined in FA97/Sch12/Para27(1) as the
lease of an asset which is not an 'existing scheme'. Paragraphs
27(2) to (4) then define an existing scheme. A lease counts as an
'existing scheme' if there was a written contract for the lease
prior to 26 November 1996 and it further satisfies one or other of
two requirements (see
BLM74635 and
BLM74640).
