While the originally notified CBA only took into account the costs strictly necessary in Trnava in order to accommodate the project, the modified version also takes into account the share of the overall fixed and common costs that can be imputed to the project.
Kui algselt esitatud analüüsis arvestati ainult Trnavas projekti läbiviimiseks vältimatult vajalikke kulusid, siis uues variandis arvestatakse ka üld- ja püsikulude selle osaga, mida saab projekti arvele kanda.
