| | z) | Fair value measurement - |
Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:
| | - | In the principal market for the asset or liability, or |
| | - | In the absence of a principal market, in the most advantageous market for the asset or liability. |
The principal or the most advantageous market must be accessible by the Group. Also, the fair value of a liability reflects its non-performance risk.
When available, the Group measures the fair value of an instrument using the quoted price in an active market for that instrument. A market is regarded as active if transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis.
If there is no quoted price in an active market, then the Group uses valuation techniques that maximize the use of relevant observable inputs and minimize the use of unobservable inputs.
The chosen valuation technique incorporates all of the factors that market participants would take into account in pricing a transaction.
All assets and liabilities for which fair value is measured or disclosed in the consolidated financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level of input used that is significant to the fair value measurement as a whole:
| | - | Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities. |
| | - | Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable. |
| | - | Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable. |
For assets and liabilities that are recognized at fair value in the consolidated financial statements on a recurring basis, the Group determines whether transfers have occurred between levels in the hierarchy by re-assessing categorization at the end of each reporting period.
For the purpose of fair value disclosures, the Group has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above.
Also, fair values of financial instruments measured at amortized cost are disclosed in Note 32.7(b).
