The work to be carried out for the compilation of this statistical operation varies according to two types of units, those subject to a restrictive budget and public accounting, and those that are not. In the first group, the revenue and expenditure under the various budget items/sub-items are allocated to the various national accounts transactions on the basis of their economic nature according to ESA criteria. In a second stage, the Non-Financial Transactions (revenue and expenditure) of each of these sub-sectors are quantified, applying the recording criteria established in the ESA.
In the case of those public entities subject to the Spanish General Chart of Accounts or any of its adaptations, classified in the General Government sector, the identification and quantification of their operations, for national accounting purposes, is carried out on the basis of the monthly information contained in their profit and loss account, variations in the balance sheet, annual report and additional questionnaires requested for this purpose.
Finally, for each of the three sub-sectors, the counterpart unit is analysed for interest transactions, current transfers and capital transfers, both in revenue and expenditure, so that in the total each transaction is the sum of the data for each sub-sector, except for the aforementioned transactions which are consolidated between sub-sectors.
