5.2. Where the amount of the contribution of the municipality established under section 1.1 is revised under section 5.1, the amount established under section 1.2 is revised using the formula provided for in section 1.2 with the following modification:B = the amount of the revised contribution of the municipality established under section 5.1.
If the amount calculated under the first paragraph is less than zero, it is deemed to be equal to zero.
An amount equal to the difference between the amount calculated under the first paragraph and the amount calculated under section 1.2 is added to or subtracted from the contribution for the following municipal fiscal year, as the case may be. If the municipality no longer receives police services after 1 January of that fiscal year and the amount cannot be added to or subtracted from the contribution, the amount is claimed from or refunded to the municipality, as the case may be. In no case does that amount bear interest.
