The company's property, plant and equipment measured at fair value at 30 June 2019 and 30 June 2018.

Non-financial assets fair value measurements – valuation processes
The company procured the service of the Jones Lang LaSalle (JLL) to undertake a comprehensive valuation of all non-financial assets at 30 June 2018. The company tests the procedures of the valuation model as an internal management review at least once every 12 months (with a formal revaluation undertaken once every three years). If a particular asset class experiences significant and volatile changes in fair value (i.e. where indicators suggest that the value of the class has changed materially since the previous reporting period), that class is subject to specific valuation in the reporting period, where practicable, regardless of the timing of the last specific valuation. The company has engaged JLL to provide written assurance that the models developed comply with AASB 13.

Significant inputs utilised by the company are derived and evaluated as follows:

Leasehold Improvements – Physical Depreciation and Obsolescence
Assets that do not transact with enough frequency or transparency to develop objective opinions of value from observable market evidence have been measured utilising the Depreciated Replacement Cost approach.

Sensitivity of inputs:
Leasehold Improvements & Property, Plant and Equipment – Consumed economic benefit / Obsolescence of asset
The significant unobservable inputs used in the fair value measurement of the Company’s leasehold improvements asset classes relate to the physical depreciation and obsolescence deduction. A significant increase (decrease) in this input would result in a significantly lower (higher) fair value measurement.

Movement in the carrying amounts for each class of property, plant & equipment between the beginning and the end of the current financial year:

Asset Revaluation
The company’s tangible non-finanical assets were independently valued at 30 June 2018 by JLL. The valuation was based on fair value. Through this review process, a revaluation gain of $1,041 related to the leasehold improvement being recognised in the assets revaluation reserve, a revaluation loss of $1,548 related to the plant and equipment being recognised in the comprehensive income.

At 30 June 2019 the directors reviewed the key assumptions made by the valuers at 21 May 2018 They have concluded that these assumptions remain materially unchanged.
