AD+(IRV-RV)×PF366 where–

IRV is the increased rateable value of those lands and heritages;
RV is their rateable value immediately prior to the effective day; and
PF has the same meaning as in regulation 9(1).
(2) Where the rateable value of lands and heritages to which this Part applies is reduced with effect from a day in the relevant year, the amount payable as rates in respect of those lands and heritages for any day in the relevant year on or after that effective day shall, subject to Parts IV to VI, be calculated in accordance with the formula–
AD×RRVRV where–
AD and RV have the same meanings as in paragraph (1); and
RRV is the reduced rateable value of those lands and heritages.
(3) Where the rateable value of lands and heritages is changed for a second or subsequent time whilst this Part applies to them, paragraphs (1) and (2) shall have effect with the substitution, in the definition of “AD” in paragraph (1), for “whichever of regulations 11(1) or 12 applies” of “this paragraph or paragraph (2)”.
