Inflation assumption*

DTF long-term forecast

"A balanced view of long-term inflation"

* The "Old" Partnerships Victoria methodology described here is the general methodology applicable to most projects. The Partnerships Victoria guidance also set out a special methodology for projects where there is material systematic risk transfer. The special methodology was much the same as the new National PPP Guidelines methodology.

* This is the inflation assumption to be used (if required) to convert between real and nominal discount rates. It is not necessarily the inflation assumption used for escalation purposes which is determined in accordance with Annexure 5. It is expected that the rate determined in accordance with Annexure 5 will be a balanced view of long-term inflation.
