General Government Gross Debt (or Maastricht Debt) is defined as debt liabilities of government in the categories Currency and Deposits, Debt Securities and Loans. Its compilation is the responsibility of the Central Statistics Office (CSO) who publish annual and quarterly estimates on the CSO website. Liabilities related to public-private partnerships (PPPs) which are classified off-balance sheet are not recorded as part of the General Government Gross Debt. The CSO do not compile a public sector net debt figure. The General Government Net Debt figure published by the CSO comprises General Government Gross Debt less government assets recorded under the same instrument categories as those contributing to General Government Gross Debt. Therefore it does not include liabilities of off-balance sheet PPPs.
