This article presents recent statistics on the structure of general government debt and its relationship to gross domestic product (GDP) in the European Union (EU). In the context of the SGP's Excessive deficit procedure notification process, Eurostat publishes government debt data twice a year, in April and October, as well as quarterly government debt data transmitted to it in line with Regulation 549/2013 (ESA2010 transmission programme). In order to analyse the debt structure in European countries, Eurostat collects additionally results from an annual survey containing Member States' information on government gross debt by sector of debt holder, by instrument, by initial and remaining maturity and by currency of issuance. The survey also contains information on (one-off) guarantees granted by the general government to non-government units as well as the market value of the Maastricht debt instruments and the apparent cost of government debt. One-off guarantees are contingent liabilities which are not included in general government gross debt.
