The Budget Project Plan provides details on the timing of the release of parameters. All parameters released to departments and agencies are classified 'Highly Protected'. Due to this classification agencies will need to put in place special arrangements before parameters will be released to them. When parameters are released they will be faxed to agencies via secure fax. If agencies do not have access to a secure fax they will need to make arrangements with another agency to use their secure fax.
Price adjustment is done by applying a deflator to constant price estimates.
Before these estimates can be indexed, it is necessary to convert the headline CPI forecast into a year on year index number. This number is then used to form a cumulative index. These two steps are shown in the table below. In the budget year, estimates for new items are already in the correct price base since this price base is factored into initial costings. The impact on the balance sheet would also need to be updated as a result of the change in expenses.
