3.17 Provisions
Provisions are recognized when the Group has a present obligation (legal or constructive) as a result of a past event and it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. The risks and uncertainties that inevitably surround many events and circumstances are taken into account in reaching the best estimate of provisions, and where the effect of the time value of money is material, the amount of provisions are the present value of the expenditures expected to be required to settle the obligation.
Provisions on confirmed and unconfirmed acceptances and guarantees, unfunded commitments of credit cards and unused credit lines of consumer and corporate loans are recognized using a valuation model that applies the credit conversion factor, probability of default, and loss given default.
Provisions are reviewed at the end of each reporting period and adjusted to reflect the current best estimate. If it is no longer probable that an outflow of resources embodying economic benefits will be required to settle the obligation, the provisions are reversed.
If the Group has a contract that is onerous, the present obligation under the contract is recognized and measured as provisions. An onerous contract is a contract in which the unavoidable costs of meeting the obligations under the contract exceed the economic benefits expected to be received under it. The unavoidable costs under a contract reflect the minimum net cost to exit from the contract, which is the lower of the cost of fulfilling it and any compensation or penalties arising from failure to fulfill it.
