The reference periods as well as the methods for the evaluation and territorial distribution of the expenditure carried out by the department and appearing in the administrative accounts prior to the transfer of each competence are determined by a two-thirds majority of the members of the commission mentioned in Article L. 3663-3. Failing agreement by the members of the commission, the right to compensation for transferred investment costs is equal to the average expenditure, excluding tax and amortisation of debt capital, net of European funds and assistance funds received by the department, shown in the department’s administrative accounts, relating to the territory of the Lyon metropolis and recorded over the five financial years preceding the date of creation of the metropolis. In the absence of agreement by the members of the commission, the right to compensation for the operating costs transferred is equal to the average updated expenditure shown in the administrative accounts of the department, relating to the territory of the metropolis of Lyon and recorded over the three financial years preceding the date of creation of the metropolis. The expenditure taken into account to determine the right to compensation is updated at the average annual growth rate of this expenditure recorded over the three financial years concerned.
