Seasonal Factors
The annual seasonal reanalysis has been undertaken on data up to September 2005. This has resulted in revisions to the seasonally adjusted and trend estimates for some series. Each year a seasonal reanalysis is performed on all time series to re-estimate and assess the appropriateness of any prior corrections which have previously been applied.
Revisions
As foreshadowed in the July 2005 issue, ABS has been undertaking quality assurance activity on housing loan outstandings associated with securitisation programs. Estimates for housing loan outstandings associated with securitisation programs in table 12 of this issue have been revised from March 2002 to June 2005. These revisions are in respect of loan outstandings only, and have not resulted in revisions to loan commitments data tabulated elsewhere in this publication.
In the last issue, data quality assurance procedures identified misreporting in the state breakdown of owner occupied housing commitments for September. The ABS estimated the state breakdown of the number and value of refinancing commitments for owner occupied housing. These estimates have been replaced with corrected reported values.
