(i) Land controlled by the PTA has been revalued as at 1 July 2011 by Landgate (Valuation Services) and Burgess Rawson. The valuations were performed during the year ended 30 June 2012 and recognised at 30 June 2012. The fair value was determined by reference to market values. See note 2(g).

To ensure the valuations provided by Valuation Services were compliant at 30 June 2012 with the fair value requirements under AASB 116, Valuation Services provided the Department of Treasury with information that tracked the general movement in the market value of land and in building construction costs from the 1 July 2011 (the date of valuation) to 30 June 2012. Department of Treasury reviewed the information and determined that the valuations provided by Valuation Services (as at 1 July 2011) were compliant with fair value requirements for 30 June 2012 reporting without further adjustment by reference to market values based on existing use.

Land and buildings which are commercially leased were independently valued on the capitalised value of current lease by Burgess Rawson. The valuations were performed during the year ended 30 June 2012 and recognised at 30 June 2012.

(iii) Freight network infrastructure was revalued on 30 June 2010 at depreciated replacement cost. A model was developed using independent third party audited information, engineering and independent valuers. As a reliable market value does not exist for the freight network infrastructure the effect and disclosure on the current and future periods cannot be determined.
