In application of the last paragraph of article L. 1424-35, when the board of directors has not set the provisional amount of revenue for the departmental or territorial fire and rescue service on 15 December of the year preceding the financial year, this is equal, taking into account, where applicable, any transfer operations that have taken place during the year, to the amount of contributions from these local authorities and public establishments recorded in the last known administrative account, corrected by the change, on that date, in the latest INSEE index of the annual average consumer price and increased by expenditure linked to the old-age-technical slide.
When, on 1 January of the year in question, there is no decision by the Board of Directors to set the methods for calculating the contributions of the département, the communes and the public establishments for inter-communal cooperation, the contribution of these authorities and establishments to the provisional amount of revenue is apportioned as follows:
The contribution of each commune and each public establishment for inter-communal cooperation is equal to:
a) For 80% of its amount to the share of the commune or public establishment for inter-communal cooperation in the total contributions of the communes and public establishments for inter-communal cooperation recorded in the most recent administrative account of the departmental fire and rescue service, corrected, where applicable, to take account of transfer operations that occurred during the year ;
b) For 20% of its amount, the product of the population multiplied by the relative difference between the average per capita tax potential of all the communes in the same demographic group and the per capita tax potential of the commune or public establishment for inter-communal cooperation.
The per capita tax potential is calculated by applying the provisions of article L. 2334-4. For public establishments for inter-municipal cooperation, the per capita fiscal potential is equal to the ratio between the average fiscal potential of the member municipalities and the average population of these municipalities.
These data are assessed on 1st January of the year preceding the financial year for which the contribution is calculated, with the exception of the population calculated under the conditions provided for in article L. 2334-2.
The municipalities are classified by demographic groups determined according to the size of their population. The demographic groups are defined in accordance with Article L. 2334-3.
The public establishments for inter-municipal cooperation are classified in the manner defined in the preceding paragraph according to the average population of their member communes.
