TOTAL SELECTED INDUSTRIES
For Total selected industries in 2009-10, applying off-June year adjustments resulted in an $8.1b (1%) increase in the estimate for IVA. Similarly, estimates of total income and total expenses increased by $14.0b (0.6%) and $11.6b (0.5%) respectively, and the off-June year adjusted estimate of wages and salaries was $1.0b (0.2%) higher than the original estimate.
In 2008-09, for Total selected industries, off-June adjustments decreased the original estimate of IVA by $2.3b. Estimates of total income and total expenses decreased by $16.2b and $17.8b respectively, and the off-June year adjusted estimate of wages and salaries increased by $1.5b.
In both years, differences between off-June adjusted estimates and original estimates for wages and salaries were minor, generally tending to increase slightly. In both 2008-09 and 2009-10, the largest adjustments were to Mining ($0.4b and $0.5b respectively) and Education and training ($0.2b and $0.3b respectively). This is consistent with these two industries exhibiting the greatest percentage of units reporting for an off-June year (see Table 1).
Differences between original and off-June adjusted total income estimates in 2009-10 were driven by increases in Mining ($6.5b) and Wholesale trade ($3.1b). In 2008-09, differences between original and off-June adjusted total income estimates were primarily a result of decreases in Manufacturing ($8.4b) and Wholesale trade ($7.8b). These movements likely reflect the subdued performance of the above industries during 2009, as a result of the global financial crisis and softening commodity prices during this period.Total income estimates for Education and training and Health care and social assistance remained unchanged, as off-June adjustment factors were not able to be generated for this data item for these industries (see 'Scope and Population' in Chapter 2).
Differences between original and off-June adjusted total expenses estimates in 2009-10 were driven by increases in Wholesale trade ($4.8b) and Mining ($3.1b), while original and off-June adjusted estimates of total expenses in 2008-09 differed mainly due to decreases in Wholesale trade ($10.6b) and Manufacturing ($7.9b).
The increases in off-June adjusted IVA estimates in 2009-10 were primarily a result of increases in Mining ($4.0b) and Manufacturing ($2.4b). In 2008-09, although alterations to the IVA estimate were relatively small overall, differences were almost entirely driven by a decrease in Manufacturing ($2.5b).
These findings demonstrate that changes in the key estimates of IVA, total income and total expenses were mostly attributable to substantial movements in the Mining, Manufacturing and Wholesale trade industries. As demonstrated in Table 1, the off-June reporting businesses in these industries make a substantial contribution to estimates of IVA, and the extent of variation between original and off-June adjusted estimates indicates that these industries were influenced by fluctuations in trading conditions over time. Conversely, although off-June reporting businesses also made a significant contribution to estimates of IVA in Education and training (Table 1), off-June adjusted estimates differ only marginally from original values, indicating that this industry experienced minimal variation in trading conditions over time.
In general, the results presented above were in line with initial expectations, and provide an estimate of the extent of variation caused by the issue of off-June reporting in EAS.
