INTRODUCTION
7 Trend estimates are derived by applying a 13-term Henderson moving average to the seasonally adjusted series. The 13-term Henderson average (like all Henderson averages) is symmetric, but as the end of a time series is approached, asymmetric forms of the average are applied. While the asymmetric weights enable trend estimates for recent months to be produced, they result in revisions to the estimates for the most recent six months as additional observations become available. There may also be revisions because of changes in the original data and as a result of the re-estimation of the seasonal factors. Details of trend-cycle weighting patterns are available on request from Time Series Analysis Section on 02 6252 6076. SIGN CONVENTION 8 In keeping with balance of payments conventions, credit entries are shown without sign and debit items are shown as negative entries. However, references to debit items in Key Figures, Key Points, and Analysis and Comments are made without regard to sign. COMMODITY BREAKDOWNS OF GOODS 9 For details of the classification used for rural and non-rural goods see table 6.6 in Balance of Payments and International Investment Position, Australia: Concepts, Sources and Methods, 1998 (Cat. no. 5331.0). 10 Table 6.7 in 5331.0 provides details of the classification used for goods debits. Most of the 25 commodity groups shown in table 4 for merchandise goods debits are further sub-divided into a total of 106 commodity sub-groups. The information at this level is available as a special data service, and can be obtained from Balance of Payments Section on Canberra 02 6252 7590. COMMODITY BREAKDOWNS OF SERVICES 11 The quarterly detailed services data published in Table 6 are consistent with the monthly aggregates shown in Table 5. Subject to confidentiality constraints, a further breakdown of services data on a quarterly basis is available on request. Detailed annual data are published for 49 services commodities in the annual publication, Balance of Payments and International Investment Position, Australia (Cat. no. 5363.0). Services trade data by major partner countries and by Australian State of production/consumption are published on a financial year basis and a calendar year basis in feature articles in this publication. Additional detail and additional presentations of the data are available on request. For further information contact Balance of Payments Section on Canberra 02 6252 5336. 12 Monthly indicators for many of the services components that are surveyed only quarterly are not available. In particular, the Freight and Other transportation components of Total services credits are not available for publication on a monthly basis. Therefore the estimates for these items shown in table 5 are derived by dividing the quarterly estimate by three. RELATED PRODUCTS AND SERVICES 13 Detailed data on exports and imports of goods dissected by commodity and country are available on an international trade basis by contacting the National Information and Referral Service. Contact details are shown on the back of this publication. 14 Users may also wish to refer to the following publications which are available from ABS Bookshops:
