The Planning Document cites three classes of expenditure in decreasing order of obligation: those connected with commitments made by the Government, those bound to established practices such as appropriations for future labour contracts and for the National Road Agency and the State Railways, and lastly those in connection with new initiatives.
The Planning Document puts expenditures for commitments already made at € billion and gives rough estimates of the second and third classes of respectively € billion (not counting the resources for the renewal of public employment contracts, still to be determined) and € billion.
