The performance targets in the key performance area of cost-efficiency expressed in en route determined unit costs submitted by Switzerland as regards FABEC should be revised downwards to a level that is in line with the reduction of the average en route determined unit costs on Union level over the second reference period and over the combined period of the first and the second reference period. That downwards revision should include a reduction in en route determined costs over the second reference period and a revision of the forecasted traffic expressed in service units.
