text: The so-called temporary operating rule commit the government "to allow for a sharp Cyclically-Adjusted Current Budget (CACB) deterioration in the short-term during a severe economic crisis (throughout 2008-09 and 2009-10), by applying active loosening fiscal policy in addition to the automatic stabilizers, and then once the economy has emerged from the downturn, to set policies to improve the CACB each year going forward, so that it reaches balance and net debt start to decrease in the medium-term". In other words, the CACB is targeted only to reach a minimum of 0.0% in the medium term, after having been allowed temporarily to deteriorate throughout the 2008–09 and 2009-10 fiscal years. The CACB figures correspond to the commission's reported structural budget balance figures, except that it does not include the expenditure "Public sector net investment" and refrains from performing any adjustment for one-off revenues/expenditures. For comparison with the SGP's definition of structural budget balance, it shall be noted that the UK has been forecasted to spend on average 1.5% of GDP annually on "Public sector net investment" throughout the seven years from 2013–14 to 2019–20. When this extra expense is subtracted from the CACB balance, it will be equal to the commission's "structural budget balance before adjustment for one-off revenues/expenditures". As of 2015, the CACB surplus target and CACB definition has remained unchanged, but its achievement date has now been postponed from its initial set 2015-16 fiscal year to the 2017-18 fiscal year.
  The UK fiscal debt-ratio target under the "temporary operating rule", also differs from the SGP debt-ratio target, as it measure compliance with the target according to "net debt" rather than "gross debt", and only require a declining trend to start from 2015 to 2016, a target which was slightly postponed in 2015, so that it shall now only decrease starting from 2016 to 2017.
  As no MTO was nationally selected by the UK in "structural balance terms" – throughout the entire period covered by the table, the compliance colors for the UK indicate whether or not its structural balance each year respected its "Minimum MTO" as calculated in structural balance terms by the commission.
