Recognition of deferred tax assets
We recognize deferred tax effects of temporary differences between the financial statement carrying amounts and the tax basis of our assets and liabilities.
Deferred tax assets are recognized only to the extent that it is probable that the associated deductions will be available for use against future profits and that there will be sufficient future taxable profit available against which the temporary differences can be utilized, provided the asset can be reliably quantified. In estimating future taxable profit, management use "base case" approved forecasts which incorporate a number of assumptions, including a prudent level of future uncontracted revenue in the forecast period. In arriving at a judgment in relation to the recognition of deferred tax assets, management considers the regulations applicable to tax and advice on their interpretation. Future taxable income may be higher or lower than estimates made when determining whether it is appropriate to record a tax asset and the amount to be recorded. Furthermore, changes in the legislative framework or applicable tax case law may result in management reassessing the recognition of deferred tax assets in future periods.
