The metropolitan authority may neutralise the depreciation allowance for public buildings, less the amount of the annual write-back of equipment subsidies received to finance these facilities, and the depreciation allowance for equipment subsidies paid, by means of an expenditure from the investment section and a revenue from the operating section.
For the application of 20° of article L. 5217-12-1, the metropolitan authority proceeds with the annual write-back of equipment subsidies received and funds allocated to depreciable fixed assets, by means of an expense in the investment section and a revenue in the operating section. This write-back in the operating section is carried out at the same rate as the depreciation of the asset for which the subsidy was received and relates to an annual share corresponding to the amount of this subsidy in relation to the depreciation period of the subsidised asset. However, the departmental equipment grant for collèges is written back globally for an amount at most equal to the annual depreciation allowance for all school buildings and equipment.
