(a) so much of the straddling period as falls before 1 January 2006, and

(b) so much of the straddling period as falls on or after that date,

are treated as separate accounting periods for the purposes of this Chapter.

(4) But special provision is made elsewhere in this Chapter in relation to straddling periods (see sections 311, 324 and 327(4) to (7)).
