Article 25 — Calculation of unit rates Regulation (EU) 2019/317 1. Member States shall calculate the *en route* and terminal unit rates before the start of each year of the reference period. 2. Those rates shall be calculated by dividing the forecast number of total *en route* or terminal service units for the relevant year, calculated in accordance with points 1 and 2 of [Annex VIII](#_DxCrossRefBm1409944008) respectively, into the algebraic sum of the following elements: (a) the determined costs, expressed in nominal terms, for the relevant year as set in the performance plan; (b) the adjustments for inflation in accordance with [Article 26](#_DxCrossRefBm1409944007); (c) the adjustments resulting from the application of the traffic risk sharing mechanism in accordance with [Article 27(2)](#_DxCrossRefBm1409944006) to (5); (d) the adjustments resulting from the application of the cost risk sharing mechanism in accordance with [Article 28(4)](#_DxCrossRefBm1409943970) to (6); (e) the adjustments resulting from the application of the financial incentive schemes in accordance with [Article 11(3)](#_DxCrossRefBm1409943980) and (4); (f) the adjustments resulting from the modulation of air navigation charges in accordance with [Article 32](#_DxCrossRefBm1409944005); (g) the adjustments resulting from traffic variations, in accordance with Article 27(8); (h) the adjustments resulting from traffic variations, in accordance with Article 27(9); (i) a deduction of other revenue, in accordance with paragraph 3 of this Article; (j) cross-financing between *en route* charging zones, or between terminal charging zones, in accordance with point (e) of Article 15(2) of Regulation (EC) No 550/2004; (k) adjustments for differences in revenue resulting from the temporary application of the unit rate in accordance with [Article 29(5)](#_DxCrossRefBm1409943991); (l) adjustments relating to previous reference periods. 3. For the purpose of point (i) of paragraph 2, the following revenues of air navigation service providers obtained in year n shall be deducted from the determined costs as ‘other revenue’: (a) public funds obtained from public authorities, including financial support from Union assistance programmes; (b) revenue obtained from commercial activities, where the Member State or Member States concerned have decided that those revenues are to be deducted; (c) with regard to terminal air navigation services, revenue obtained from contracts or agreements concluded between air navigation service providers and airport operators, where the Member State or Member States concerned have decided that those revenues are to be deducted. As regards point (a), public funds covering staff costs and other operating costs shall be deducted from the determined costs no later than in year n+2. Public funds covering depreciation costs shall be deducted from the determined costs in accordance with the depreciation schedule of the financed asset (duration and annuity). A Member State may decide not to deduct from determined costs an amount related to the administrative costs incurred for the reporting on the funding agreement if these administrative costs are not included in the cost base for charges. Equally, a Member State may decide not to deduct from determined costs public funds received to cover costs not known at the time of drafting the performance plan and therefore not included in the cost base for charges. Airspace users shall not be charged for the costs covered by public funds. As regards points (b) and (c), the revenue referred to in those points shall be deducted from the determined costs no later than in year n+2. 4. Unit rates shall be calculated in national currency. Where Member States decide to establish a common charging zone in accordance with [Article 21(4)](#_DxCrossRefBm1409943997), the unit rate shall be calculated in a single currency, which may be the euro or another national currency of one of the Member States concerned. The Member States concerned shall notify the Commission and the CRCO of Eurocontrol of the applicable currency.
