The work to be carried out in the preparation of this statistical operation varies according to two types of unit, those subject to a restrictive budget and public accounting, and those that are not. In the first group, the income and expenditure included in the various budget concepts/sub-concepts are allocated to the various national accounting operations, depending on their economic nature according to the ESA criteria. In a second stage, the Non-Financial Operations (income and expenditure) of each of these subsectors are quantified, applying the registration criteria set out in the ESA.
In the case of those public entities subject to the General Accounting Plan of the Spanish Company or any of its adaptations, classified in the public administration sector, the identification and quantification of their operations, for the purposes of national accounting, is carried out on the basis of the monthly information contained in their profit and loss account, changes in the balance sheet, memory and additional questionnaires requested for that purpose.
Finally, for each of the three subsectors, the counterpart unit of interest transactions, current transfers and capital transfers, in terms of both income and expenditure, is analysed, so that in the total each transaction is the sum of the data of each subsector, except for the aforementioned transactions that are consolidated between subsectors.
