Recognition and measurement

Provisions are recognised when:

• there is a present legal or constructive obligation to make a future sacrifice of economic benefits as a result of past transactions or events
• it is probable that a future sacrifice of economic benefits will arise
• a reliable estimate can be made of the amount of the obligation.

The amount recognised as a provision is the best estimate of the consideration required to settle the present obligation at the reporting date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows.
