| (i) | Financial instruments |
| (i) | Classification |
The Group classifies its financial assets in the following categories:
| • | financial assets at fair value through profit or loss, |
| • | loans and receivables, |
| • | held-to-maturity investments, and |
| • | available-for-sale financial assets. |
The classification depends on the purpose for which the investments were acquired. Management determines the classification of its investments at initial recognition and, in the case of assets classified as held-to-maturity, re-evaluates this designation at the end of each reporting period. See Note 33 for details about each type of financial asset.
| (ii) | Reclassification |
The Group may choose to reclassify a non-derivative trading financial asset out of the held for trading category if the financial asset is no longer held for the purpose of selling it in the near term. Financial assets other than loans and receivables are permitted to be reclassified out of the held for trading category only in rare circumstances arising from a single event that is unusual and highly unlikely to recur in the near term. In addition, the Group may choose to reclassify financial assets that would meet the definition of loans and receivables out of the held for trading or available-for-sale categories if the Group has the intention and ability to hold these financial assets for the foreseeable future or until maturity at the date of reclassification.
Reclassifications are made at fair value as of the reclassification date. Fair value becomes the new cost or amortized cost as applicable, and no reversals of fair value gains or losses recorded before reclassification date are subsequently made. Effective interest rates for financial assets reclassified to loans and receivables and held-to-maturity categories are determined at the reclassification date. Further increases in estimates of cash flows adjust effective interest rates prospectively.
| (iii) | Recognition and derecognition |
Regular way purchases and sales of financial assets are recognized on trade date, the date on which the Group commits to purchase or sell the asset. Financial assets are derecognized when the rights to receive cash flows from the financial assets have expired or have been transferred and the Group has transferred substantially all the risks and rewards of ownership.
When securities classified as available-for-sale are sold, the accumulated fair value adjustments recognized in other comprehensive income are reclassified to profit or loss as gains and losses from investment securities.
| (iv) | Measurement |
At initial recognition, the Group measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss, transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at fair value through profit or loss are expensed in profit or loss.
Loans and receivables and held-to-maturity investments are subsequently carried at amortized cost using the effective interest method.
Available-for-sale financial assets and financial assets at fair value through profit or loss are subsequently carried at fair value. Gains or losses arising from changes in the fair value are recognized as follows:
| • | for ‘financial assets at fair value through profit or loss’ – in profit or loss |
| • | for available-for-sale financial assets that are monetary securities denominated in a foreign currency – translation differences related to changes in the amortized cost of the security are recognized in profit or loss and other changes in the carrying amount are recognized in other comprehensive income |
| • | for other monetary and non-monetary securities classified as available-for-sale – in other comprehensive income |
Dividends on financial assets at fair value through profit or loss and available-for-sale equity instruments are recognized in profit or loss when the Group’s right to receive payments is established.
Details on how the fair value of financial instruments is determined are disclosed in Note 33.
| (iv) | Impairment |
The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or group of financial assets is impaired. A financial asset or a group of financial assets is impaired and impairment losses are incurred only if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset (a ‘loss event’) and that loss event has an impact on the estimated future cash flows of the financial asset or group of financial assets that can be reliably estimated. In the case of equity investments classified as available-for-sale, a significant or prolonged decline in the fair value of the security below its cost is considered an indicator that the assets are impaired.
For loans and receivables, the amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset’s original effective interest rate. The carrying amount of the asset is reduced and the amount of the loss is recognised in profit or loss. If a loan or held-to-maturity investment has a variable interest rate, the discount rate for measuring any impairment loss is the current effective interest rate determined under the contract. As a practical expedient, the Group may measure impairment on the basis of an instrument’s fair value using an observable market price.
If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtor’s credit rating), the reversal of the previously recognized impairment loss is recognized in profit or loss.
Impairment testing of trade receivables is described in Note 33.
If there is objective evidence of impairment for available-for-sale financial assets, the cumulative loss – measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that financial asset previously recognized in profit or loss – is removed from equity and recognized in profit or loss.
Impairment losses on equity instruments that were recognised in profit or loss are not reversed through profit or loss in a subsequent period.
If the fair value of a debt instrument classified as available-for-sale increases in a subsequent period and the increase can be objectively related to an event occurring after the impairment loss was recognised in profit or loss, the impairment loss is reversed through profit or loss.
| (v) | Derecognition of financial assets |
The Group derecognizes a financial asset only when the contractual rights to the cash flows from the asset expire, or when it transfers the financial asset and substantially all the risks and rewards of ownership of the asset to another party. If the Group neither transfers nor retains substantially all the risks and rewards of ownership and continues to control the transferred asset, the Group recognizes its retained interest in the asset and an associated liability for amounts it may have to pay. If the Group retains substantially all the risks and rewards of ownership of a transferred financial asset, the Group continues to recognize the financial asset and also recognizes a collateralized borrowing for the proceeds received.
| (vi) | Income recognition |
Interest income is recognised using the effective interest method. When a receivable is impaired, the Group reduces the carrying amount to its recoverable amount, being the estimated future cash flow discounted at the original effective interest rate of the instrument, and continues unwinding the discount as interest income. Interest income on impaired loans is recognised using the original effective interest rate.
Dividends are recognised as revenue when the right to receive payment is established. This applies even if they are paid out of pre-acquisition profits. However, the investment may need to be tested for impairment as a consequence.
| (vii) | Derivative financial instruments |
Forward foreign exchange, interest rate and foreign exchange swaps (IRS, Cross Currency Swaps etc.) and option transaction fair values are calculated with market levels of interest rates and Central Bank of Republic of Turkey (CBRT) exchange rates via Bloomberg financial terminal. If market levels are not available for valuation date, fair value for forward contracts will be value of discounted future value of difference between contract price level and forward value of CBRT exchange rate with risk fee rates for the period. Interest rate and currency swaps will be valued with the difference of discounted cash flows of each leg of the swaps using risk free rates and CBRT exchange rates. Option transactions will be valued with option pricing models using risk free rates and CBRT exchange rates.
| (viii) | Offsetting financial assets and financial liabilities |
Financial assets and liabilities are offset and the net amount presented in the statement of financial position where the Group has a legally enforcable right to offset the recognized amounts, and there is an intention to settle on a net basis or to realize the asset and settle the liability simultaneously.
