If a specified year is not a revaluation year, a billing authority’s baseline amount in respect of a designated area for the specified year is the amount calculated under sub-paragraph (2) or (3).

• K₂ is the small business non-domestic rating multiplier for the specified year; and

• K₁ is the small business non-domestic rating multiplier for the preceding year.

For a subsequent specified year which is not a revaluation year, the baseline amount is calculated in accordance with the formula—

$$L\times \frac{M2}{M1}$$

where—

• L is the amount calculated under sub-paragraph (2), this sub-paragraph or paragraph 5(1) for the preceding year;

• M₂ is the small business non-domestic rating multiplier for the specified year; and

• M₁ is the small business non-domestic rating multiplier for the preceding year.
