Fair value of derivative instruments and risk management
This section explains the judgments and estimates made in determining the fair values of the financial instruments that are recognized and measured at fair value in the financial statements. To provide an indication of the reliability of the inputs used in determining fair value, the Group has classified its financial instruments into the three levels prescribed under the accounting standards. An explanation of each level is as follows:
 
  
Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity can access at the measurement date;
 
  
Level 2 inputs are inputs, other than quoted prices included within Level 1, that are observable for the asset or liability, either directly or indirectly; and
 
  
Level 3 inputs are unobservable inputs for the asset or liability.

(*)
Since the
bid-ask
spread is unobservable input; in the valuation of participating cross currency swap contracts, prices in the
bid-ask
price range that were considered the most appropriate were used instead of mid prices. If mid prices were used in the valuation the fair value of participating cross currency swap contracts would have been TL 116,684 lower as at 31 December 2019 (31 December 2018: TL 123,995).
There were no transfers between fair value hierarchy levels during the year.

Net off / Offset
The Company signed a Credit Support Annex (CSA) against the default risk of parties in respect of a EUR 433,400 participating cross currency swap transaction executed on 15 July 2016 and restructured respectively on 26 May 2017 and 9 August 2018. Additionally, in the 25 June 2019, The Company signed a new CSA to EUR 56,004 participating cross currency swap transaction. As per the CSA, the swap’s current
(mark-to-market)
value will be determined on the 10th and 24th calendar day of each calendar month, and if the
mark-to-market
value is positive and exceeds a certain threshold, the bank will be posting cash collateral to the Company which will be equal to an amount exceeding the threshold (i.e. if the
mark-to-market
value is negative, the Company would be required to post collateral to the bank by an amount exceeding the threshold).
With respect to valuations, on a
bi-weekly
basis, a transfer will take place between the parties only if the
mark-to-market
value changes by at least EUR 1,000. Following the execution of CSA, the bank transferred to the Company EUR 224,843 as collateral (31 December 2019: TL 1,495,341) which was the amount exceeding the threshold and the Company transferred EUR 99,473 as collateral to the bank (31 December 2019: TL 661,555) which was the amount exceeding the threshold. The Company clarified this with the derivative assets included in the statement of financial position because it has the legal right to offset the collateral amount TL 833,786 that it recognizes under the borrowings and intends to pay according to the net fair value. This amount was netted from the borrowings and deducted from the derivative instruments in the balance sheet. As of 31 December 2019, were this transaction not conducted, derivative financial instruments assets would have been TL 1,679,299 and current borrowings TL 8,462,119.
 
Market risk
The Group uses various types of derivatives to manage market risks. All such transactions are carried out within the guidelines set by the treasury and risk management department. Generally, the Group seeks to apply hedge accounting to manage volatility in profit or loss.
Currency risk
The Group’s risk management policy is to hedge its estimated foreign currency exposure in respect of borrowing payments with various maturities at any point in time. The Group uses participating cross currency contracts to hedge its currency risk, mostly with a maturity of over one year from the reporting date. These contracts are generally designated as cash flow hedges.
The Group designates the hedge ratio, between the amount of the hedged item and the hedging instrument is 1:1 to hedge its currency risk.
The time value of options in participating cross currency swap contracts are included in the designation of the hedging instrument and are separately accounted for as a cost of hedging, which is recognized in equity in a cost of hedging reserve. The Group’s policy is for the critical terms of the participating cross currency contracts to align with the hedged item.
The Group determines the existence of an economic relationship between the hedging instruments and hedged item based on the currency, amount and timing of their respective cash flows. The Group assesses whether the derivative designated in each hedging relationship is expected to be and has been effective in offsetting changes in cash flows of the hedged item using the hypothetical derivative method.
In these hedge relationships, the main sources of ineffectiveness are;
 
  
The effect of the counterparties’ credit risk on the fair value of the swap contracts, which is not part of the hedged risk and associated credit risk considered to be very low at inception in the fair value of the hedged cash flows attributable to the change in exchange rates;
 
  
The entire fair value of the derivative contracts including currency basis was designated as the hedging instrument in cash flow hedge. The hypothetical derivative is modelled to exclude the impact of currency basis.
Interest rate risk
The Group adopts a policy of ensuring that its interest rate risk exposure is at a fixed rate. This is achieved partly by entering into fixed-rate instruments and partly by borrowing at a floating rate and using cross currency and interest rate swaps as hedges of the variability in cash flows attributable to movements in interest rates. The Group applies a hedge ratio of 1:1.
The Group determines the existence of an economic relationship between the hedging instrument and hedged item based on the reference interest rates, tenors, repricing dates and maturities and the notional or par amounts.
The Group assesses whether the derivative designated in each hedging relationship is expected to be effective in offsetting changes in cash flows of the hedged item using the hypothetical derivative method.
In these hedge relationships, the main sources of ineffectiveness are:
 
  
The effect of the counterparties’ credit risk on the fair value of the swap contracts, which is not part of the hedged risk and associated credit risk considered to be very low at inception in the fair value of the hedged cash flows attributable to the change in interest rates;
 
Cash flow sensitivity analysis for variable-rate instruments
A reasonable potential change of 100 basis points in interest rates and 10% change in foreign exchange currency at the reporting date would have increased (decreased) equity and profit or loss by the amounts shown below. This analysis assumes that all other variables remain constant.
