The purpose of the Portfolio Additional Estimates Statements (PAES), like that of the Portfolio Budget Statements (PB Statements), is to inform Senators and Members of Parliament of the proposed allocation of resources to Government outcomes by agencies within the portfolio. The focus of the PAES differs from the PB Statements in one important aspect. While the PAES include an Agency Resource Statement to inform Parliament of the revised estimate of the total resources available to an agency, the focus of the PAES is on explaining the changes in resourcing by outcome(s) since the Budget. As such, the PAES provides information on new measures and their impact on the financial and/or non-financial planned performance of programs supporting those outcomes.
The PAES facilitate understanding of the proposed appropriations in Appropriation Bills (No. 3 and No. 4) 2012-13. In this sense the PAES is declared by the Additional Estimates Appropriation Bills to be a 'relevant document' to the interpretation of the Bills according to section 15AB of the Acts Interpretation Act 1901.
Whereas the Mid-Year Economic and Fiscal Outlook 2012-13 is a mid-year budget report which provides updated information to allow the assessment of the Government's fiscal performance against its fiscal strategy, the PAES update the most recent budget appropriations for agencies within the portfolio.
