Article 1 
1. Gross national income at market prices (GNI) and gross domestic product at market prices (GDP) shall be defined in accordance with the European System of Accounts 2010 (ESA 2010) established by Regulation (EU) No 549/2013. 2. In accordance with point 8.89 of Annex A to Regulation (EU) No 549/2013, GDP means the final result of the production activity of resident producer units. It can be defined in three ways: (a) production approach: GDP is the sum of gross value added of the various institutional sectors or the various industries plus taxes and less subsidies on products (which are not allocated to sectors and industries). It is also the balancing item in the total economy production account; (b) expenditure approach: GDP is the sum of final uses of goods and services by resident institutional units (final consumption and gross capital formation) plus exports and minus imports of goods and services; (c) income approach: GDP is the sum of uses in the total economy generation of income account (compensation of employees, taxes on production and imports less subsidies, gross operating surplus and mixed income of the total economy). 3. In accordance with point 8.94 of Annex A to Regulation (EU) No 549/2013, GNI means the total primary income receivable by resident institutional units: compensation of employees, taxes on production and imports less subsidies, property income (receivable less payable), gross operating surplus and gross mixed income. GNI equals GDP minus primary income payable by resident institutional units to non-resident institutional units plus primary income receivable by resident institutional units from the rest of the world.
