A number of accounting policies and disclosures require the determination of fair value, for both financial and non-financial assets and liabilities. The methods for determining fair values are described below. When applicable further information about the assumptions made in determining fair values is disclosed in the notes specific to that asset or liability.
The fair value of derivatives is calculated based on their quoted closing bid price at the balance sheet date or, in the lack thereof, other inputs that are observable for the asset or liability, either directly (i. e. as prices) or indirectly (i. e. derived from prices). In the second case, the fair value of derivatives is estimated as the present value of future cash flows, discounted using the market interest rate at the reporting date. Information on the structure of Polish and eurozone interest rates and Polish złoty exchange rate are used in order to estimate future cash flows and market interest rate.
(ii) Non-derivative financial assets
The fair value of non-derivative financial asset for disclosure purposes is estimated as the present value of future cash flows discounted using the market rate of interest rate as at the balance sheet date.
(iii) Non-derivative financial liabilities
Fair value, which is determined for disclosure purposes, is calculated based on liabilities’ quoted closing bid price at the balance sheet date or, in the lack thereof, estimated on the present value of future principal and interest cash flows, discounted using the market interest rate at the reporting date. Market interest rate is estimated as interbank interest rate for a given currency zone (WIBOR, EURIBOR) plus a margin regarding the Group’s credit risk. A market interest rate for a finance lease contract is estimated based on interest rates for similar lease contracts.
