Z is the small business non-domestic rating multiplier for the financial year beginning in 2016.
(2) The amount referred to in sub-paragraph (1) is the amount certified by the appropriate valuation officer as the rateable value which would have been shown in the list for the hereditament for 31st March 2017 on the assumption that—

The notional chargeable amount for a relevant year for an altered hereditament is found by applying the formula—
A×D
