The new methodology was called for in the 2005 code of conduct on implementation of the EU's stability and growth pact, in order to ensure that the member states' budgetary strategies reflect real medium-term needs, by taking account not just of debt levels but also implicit liabilities, notably costs related to ageing populations, in particular projected healthcare and pension expenditure.
Uut metodoloogiat on vaja seoses ELi stabiilsus- ja kasvupakti rakendamise 2005. aasta tegevusjuhendi nõuetega, et tagada tegelike keskpika perioodi vajaduste kajastumine liikmesriikide eelarvestrateegiates, arvestades mitte ainult võlataset, vaid ka bilansiväliseid kohustusi, eriti vananeva elanikkonnaga kaasnevaid kulusid, eelkõige planeeritavaid kulutusi tervishoiule ja pensionile.
