During the transposition period, there were some arguments raised by Member States that existing public tariffs do not represent a comparable price because important elements, for example from general taxation (e.g. capital investment costs), are not represented in the public tariff which is not fully cost-recovering.
Des éléments importants, tels que la fiscalité générale (par exemple les coûts d'investissement), ne sont pas représentés dans les tarifs publics qui ne couvrent pas totalement les coûts.
