(12)The expected improvement in cost-efficiency for the second reference period should be measured against determined costs for 2014 of EUR 6,242 millionnote in EUR2009. On the basis of the most recent traffic assumptions for 2014note, the baseline value for the determined unit cost should be EUR 58,09 in EUR2009. Thus, the cost-efficiency target should provide for a reduction in determined unit costs by 3,3 % per year over the second reference period. The baseline value of EUR 58,09 in EUR2009 is higher than the Union-wide performance target of EUR 53,92 in EUR2009 set for 2014, because the projected traffic volume for 2014 is lower than originally assumed in Commission Decision 2011/121/EUnote.
