9.5 Financial instruments

Derivative financial instruments As part of its interest rate risk on mid and long-term liabilities managing policy, the Group uses derivative financial instruments. These consist of interest rate swaps and cross-currency swaps matched with bond issues and bank loans. Interest rate swaps are initially and subsequently valued in the balance sheet at their fair value through the income statement. Changes in the fair value of derivative instruments are recognized through the income statement, with the exception of particular cases in respect of hedge accounting set out below. Where a financial instrument can be qualified for hedge accounting, it is valued and accounted for in accordance with hedge accounting criteria contained in IFRS 9: ¯ if the derivative is designated as a cash flow hedge, changes in the value of the effective part of the derivative are recorded in other elements of the comprehensive income statement and are presented in fair value reserves within equity capital. They are taken to the income statement when the hedged item is itself recognized in the income statement. Conversely, the ineffective part of the derivative is recognized directly in the income statement. Where the hedged transaction is a future debt issue, the reclassification to the income statement is carried out over the term of the debt issue, once the issue has taken place. When the forecasted transaction leads to the recognition of a non-financial asset or liability, the cumulative changes in the fair value of a hedging instrument formerly recognized through shareholders’ equity are included in the initial valuation of the asset or liability in question; ¯ if the derivative instrument is designated as a fair value hedge, changes in the value of the instrument and of the hedged item are recognized in the income statement in the same period; ¯ a hedge of a net investment in a foreign entity receives the same accounting treatment as a cash flow hedge. Changes in the fair value of the hedging instrument are recognized in equity, for the effective part of the hedging relationship, whereas changes in connection with the ineffective part of the hedge are recognized in net finance costs. When the investment in the foreign entity is sold, all changes in the fair value of the hedging instrument previously recognized through equity are transferred to the income statement.

Hedge accounting is applicable if the hedging relationship is clearly defined and documented when it is set up and if the effectiveness of the hedging relationship is demonstrated prospectively and retrospectively at the initial date and at each subsequent closing period, to ensure that an economic relationship exists between the hedged item and hedging instrument. Derivatives are entered on the assets side of the balance sheet under “Other current financial assets” or on the liabilities side under “Current debt”. Such derivatives can be cancelled at any time by paying or receiving a cash amount corresponding to their fair value. The best criterion for measuring the fair value of a contract is the price agreed upon between a buyer and seller operating on a free market under market conditions. At the date of the agreement, this is generally the transaction price. Subsequently, the value of the contract must be based on observable market data which constitute the most reliable indication of fair value for financial instruments: ¯ updated future cash flows for bonds and bank loans; ¯ quoted prices on an organized market for non-consolidated listed investments; ¯ market value for interest rate and foreign exchange instruments, valued using discounting of differential future cash flows or on the basis of quoted prices issued by third party financial institutions. The fair value for forward contracts to sell foreign currencies corresponds to the difference between the currency amounts converted at the contractually fixed rates for each maturity and the currency amounts converted at the forward rate for the same maturities. The fair value of a financial instrument reflects the effect of non- performance risk: the counterparty credit risk (Credit Valuation Adjustment – CVA) and the own credit risk of Aéroports de Paris SA (Debit Valuation Adjustment – DVA). For derivatives, the Group has elected to determine the CVA using a mixed model including market data (use of counterparty’s spreads CDS) and historical statistic data.
