Note 27 - Measurement of fair value of financial instruments

Financial instruments at fair value are classified at various levels. 

Level 1: Valuation based on quoted prices in an active market
Fair value of financial instruments that are traded in the active markets is based on market price on the balance sheet date. A market is considered active if market prices are easily and regularly available from a stock exchange, dealer, broker, industry group, price-setting service or regulatory authority, and these prices represent actual and regularly occurring market transactions at an arm’s length. This category also includes quoted shares and Treasury bills. 

Level 2: Valuation based on observable market data
Level 2 consists of instruments that are valued by the use of information that does not consist in quoted prices, but where the prices are directly or indirectly observable for the assets or liabilities concerned, and which also include quoted prices in non-active markets.

Level 3: Valuation based on other than observable data
If valuation data are not available for level 1 and 2, valuation methods are applied that are based on non-observable information.
