10. The community shall, regarding the amount of any contribution, abstain from providing for a maximum or provide only for the maximum that results from the application of the rules prescribed in the second, third and fourth paragraphs.
For each municipality that must contribute to the sharing, a quotient is calculated by dividing the amount of the municipality’s contribution by its population. The average of the quotients calculated is then determined.
If the quotient calculated for a municipality is in excess of five times the average, the amount of the municipality’s contribution is reduced to eliminate the amount in excess.
The second paragraph does not apply again to take into account the new amount of contribution resulting from the reduction provided for in the third paragraph.
