Estimates for each quarter of the NTI are revised when those for subsequent quarters of the same year are published. At the time of the first quarter of each year, revisions are made back four to six years, depending on the timing of the last TSA. They are not normally revised again except when historical revisions are carried out. Statistical revisions are carried out in order to incorporate the most recent information from the income and expenditure accounts, quarterly and annual surveys, as well as from benchmarking to the most recent tourism satellite account.
