Government Finance Statistics (GFS) provide information on the finances of public sector entities classified in a uniform and systematic way and provide for analysis of the impact of government finances on the rest of the economy. The statistics are produced on an accrual basis, in which revenues, expenses, assets and liabilities are recorded as they are earned, accrued or incurred, regardless of when cash changes hands. Cashflow data are also compiled to supplement the accrual data. The accrual series commenced in 1998-99. GFS for the years 1961-62 to 1997-98 were only prepared on a cash basis.
