Amount of post-commencement supplement for a post-commencement period

Section 322 explains how to calculate the amount of the post-commencement ring fence expenditure supplement for a given post-commencement period.

• The supplement for a post-commencement period is calculated by applying the relevant percentage to the reference amount for that period.
• If the post-commencement period is shorter than 12 months, the supplement is reduced proportionally to reflect the shorter period.
• The relevant percentage used in the calculation is specified separately in section 310 of the Act.
• The reference amount for a post-commencement period is determined by following the rules set out in sections 325 to 329 of the Act.
