b) Correction of financial statements during the hyperinflationary periods

In accordance with the decision of the CMB dated 28 December 2023 and numbered 81/1820, it has been decided that issuers and capital market institutions subject to financial reporting regulations that apply Turkish Accounting/Financial Reporting Standards will apply inflation accounting by applying the provisions of TAS 29 "Financial Reporting Standard in Hyperinflationary Economies" starting from their annual financial reports for the accounting periods ending as of 31 December 2024. In addition, with the statement made by the Public Oversight Accounting and Auditing Standards Authority (KGK) on 23 November 2023, businesses applying TFRS have started to apply inflation accounting in accordance with TAS 29 Financial Reporting Standard in Hyperinflationary Economies starting from their financial statements for the annual reporting period ending on or after 31 December 2024. TAS 29 is applied to the financial statements, including the consolidated financial statements, of businesses whose functional currency is the currency of a hyperinflationary economy.

Prior period financial statements are also presented in the current measurement unit at the end of the reporting period for comparative purposes. The Group has therefore presented its consolidated financial statements as of 31 December 2023, on the purchasing power basis as of 31 December 2024.

The adjustments made in accordance with IAS 29 were made using the adjustment coefficient obtained from the Consumer Price Index (CPI) of Turkey published by the Turkish Statistical Institute (TURKSAT). As of 31 December 2024, the indices and adjustment coefficients used in the adjustment of the consolidated financial statements are as follows:

(All amounts disclosed in the consolidated financial statements and notes have been rounded off to the nearest thousand currency units and are expressed in terms of purchasing power of Turkish Lira as of 31 December 2024 unless otherwise stated.)

2. BASIS OF PRESENTATION OF FINANCIAL STATEMENTS (CONTINUED)

2.1 Basis of presentation of the consolidated financial statements (continued)

b) Correction of financial statements during the hyperinflationary periods (continued)

Assets and liabilities were separated into those that were monetary and non–monetary, with non– monetary items were further divided into those measured on either a current or historical basis to perform the required restatement of financial statements under TAS 29. Monetary items (other than index -linked monetary items) and non-monetary items carried at amounts current at the end of the reporting period were not restated because they are already expressed in terms of measuring unit as of 31 December 2024. Nonmonetary items which are not expressed in terms of measuring unit as of 31 December 2024 were restated by applying the conversion factors. The restated amount of a non monetary item was reduced, in accordance with appropriate TFRSs, in cases where it exceeds its recoverable amount or net realizable value. Components of shareholders' equity in the statement of financial position and all items in the statement of profit or loss and other comprehensive income have also been restated by applying the conversion factors.

The application of TAS 29 results in an adjustment for the loss of purchasing power of the Turkish lira presented in Net Monetary Position Gains (Losses) item in the profit or loss section of the statement of profit or loss and comprehensive income. In a period of inflation, an entity holding an excess of monetary assets over monetary liabilities loses purchasing power and an entity with an excess of monetary liabilities over monetary assets gains purchasing power to the extent the assets and liabilities are not linked to a price level. This gain or loss on the net monetary position is derived as the difference resulting from the restatement of non monetary items, owners' equity and items in the statement of profit or loss and other comprehensive income and the adjustment of index linked assets and liabilities.

All items included in the statement of comprehensive income, except those that affect the statement of comprehensive income of non-monetary items in the Statement of Financial Position, are indexed with coefficients calculated over the periods when the income and expense accounts are first reflected in the financial statements.

In addition, in the first reporting period in which TAS 29 is applied, the requirements of the Standard are applied as if the economy had always been hyperinflationary. Therefore, the statement of financial position at the beginning of the earliest comparative period, i.e as of 1 January 2022, was restated as the base of all subsequent reporting. Restated retained earnings/losses in the statement of financial position as of 1 January 2022 was derived as balancing figure in the restated statement of financial position. The financial statements of subsidiaries whose functional currencies are not in the hyperinflationary economy are subject to IAS 21. In this context, TAS 29 has been applied only to subsidiaries resident in Turkey, and other subsidiaries and affiliates have been evaluated and accounted within the scope of TAS 21.

As at 31 December 2024, the consolidated financial statements include the financial results of Türk Telekom and its subsidiaries that the Group has control over its financial and operational policies which are listed at Note 1.

Control is normally evidenced when the Company controls an investee if and only if the Company has all the following; a) power over the investee b) exposure, or rights, to variable returns from its involvement in the investee and c) the ability to use its power over the investee to affect the amount of company's returns. The results of subsidiaries acquired are included in the consolidated statements of income from the effective date of acquisition as appropriate.

When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies in line with those used by the Group. The consolidated financial statements are prepared using uniform accounting policies for similar transactions and events and are prepared with the same chart of accounts of the Company.

b) Business combinations

From 1 January 2010 the Group has applied revised TFRS 3 "Business Combinations" standard. The change in accounting policy has been applied prospectively and had no effect on business combinations completed during prior periods.

Business combinations are accounted for using the acquisition method as at the acquisition date, which is the date on which control is transferred to the Group. The cost of an acquisition is measured as the aggregate of the consideration transferred, measured at acquisition date fair value and the amount of any non-controlling interest in the acquirer.

The consideration transferred is measured at fair value, which is calculated as the sum of the acquisition-date fair values of the assets transferred by the Group, the liabilities incurred by the Group to former owners of the entity and the equity interests issued by the Group. When the agreement with the seller includes a clause that the consideration transferred could be adjusted for future events, the acquisition-date fair value of this contingent consideration is included in the cost of the acquisition. All transaction costs incurred by the Group have been recognized in general administrative expenses.

For each business combination, the Group elects whether it measures the non-controlling interest in the acquirer either at fair value or at the proportionate share of the acquirer's identifiable net assets.

When the Group acquires a business, it assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as at the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquirer.

Acquisition method requires allocation of the acquisition cost to the assets acquired and liabilities assumed at their fair values on the date of acquisition.

Acquired assets and liabilities and contingent liabilities assumed according to TFRS 3 are recognized at fair values on the date of the acquisition. Acquired company is consolidated starting from the date of acquisition.

If the fair values of the acquired identifiable assets, liabilities and contingent liabilities or cost of the acquisition are based on provisional assessment as at the balance sheet date, the Group made provisional accounting.

c) Transactions eliminated on consolidation

Intra-group balances and transactions, and any unrealized income and expenses arising from intragroup transactions, are eliminated in preparing the consolidated financial statements. Unrealized gains arising from transactions with associates are eliminated against the investment to the extent of the Group's interest in the investee. Unrealized losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment.

d) Foreign currency

i) Foreign currency transactions

Transactions in foreign currencies are translated to the functional currencies of the Group entities at the exchange rates ruling at the date of the transactions. Monetary assets and liabilities denominated in foreign currencies at reporting date are translated to the functional currency at the exchange rate ruling at the date. Foreign currency differences arising on translation of foreign currency transactions are recognized in the income statement, except for differences arising on qualifying cash flow hedges to the extent the hedge is effective, which are recognized in other comprehensive income.

Non-monetary assets and liabilities denominated in foreign currencies that are measured at fair value are retranslated to the functional currency at the exchange rate at the date that the fair value was determined. Non-monetary items in a foreign currency that are measured based on historical cost are translated using the exchange rate at the date of the transaction.

ii) Foreign operations

The assets and liabilities of foreign operations, including goodwill and fair value adjustments arising on acquisition, are translated to reporting currency at exchange rates at the reporting date. The income and expenses of foreign operations are translated to reporting currency at average exchange rates in the related periods.

Foreign currency differences are recognized in other comprehensive income and presented in the foreign currency translation reserve in equity.

The Group entities use USD, EUR or TL, as functional currency since these currencies are used to a significant extent in, or have a significant impact on, the operations of the related Group entities and reflect the economic substances of the underlying events and circumstances relevant to these entities. All currencies other than the functional currency selected for measuring items in the financial statements are treated as foreign currencies.

Accordingly, transactions and balances not already measured in the functional currency have been remeasured to the related functional currencies. The Group uses TL as the reporting currency.

iii)Hedge of net investment in a foreign operation

The Company acquires foreign currency bank loans in order to hedge its net investment in a foreign operation. Foreign exchange gain and/or loss resulting from the subsidiary's net investment portion of this loan is reclassified to other comprehensive income. Foreign exchange gain and/or loss resulting from the subsidiary's net investment portion of this loan reclassified to other comprehensive income will be transferred to profit and loss in case of disposal. Tax effects of foreign exchange gain and/or loss resulting from the subsidiary's net investment portion of this loan is recognized under other comprehensive income as well.

2.3 Significant accounting policies

a) Financial instruments

i. Recognition and initial measurement

Trade receivables are initially recognized when they are originated. All other financial assets and financial liabilities are initially recognized when the Group becomes a party to the contractual provisions of the instrument. A financial asset (unless it is a trade receivable without a significant financing component) or financial liability is initially measured at fair value plus, for an item not at FVTPL, transaction costs that are directly attributable to its acquisition or issue. A trade receivable without a significant financing component is initially measured at the transaction price.

ii. Classification and subsequent measurement

Financial assets

On initial recognition, a financial asset is classified as measured at: amortized cost, FVOCI – equity investment, or FVTPL.

Financial assets are not reclassified subsequent to their initial recognition unless the Group changes its business model for managing financial assets in which case all affected financial assets are reclassified on the first day of the first reporting period following the change in the business model. A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL:

  • it is held within a business model whose objective is to hold assets to collect contractual cash flows; and
  • its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.

On initial recognition of an equity investment that is not held for trading, the Group may irrevocably elect to present subsequent changes in the investment's fair value in other comprehensive income.

This election is made on an investment-by-investment basis. The Group holds 6,84% of shares of Cetel as equity investment and has elected to present changes in fair value of Cetel in other comprehensive income. Cost of Cetel is used as a measure for its fair value since management has insufficient more recent information to measure fair value.

ii. Classification and subsequent measurement (continued)

All financial assets not classified as measured at amortized cost or FVOCI as described above are measured at FVTPL. This includes all derivative financial assets (Note 15) and equity investments measured at FVTPL.

On initial recognition, the Group may irrevocably designate a financial asset that otherwise meets the requirements to be measured at amortized cost or at FVOCI as at FVTPL if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise.

Financial assets: Business model assessment

The Group makes an assessment of the objective of the business model in which a financial asset is held at a portfolio level because this best reflects the way the business is managed and information is provided to management. The information considered includes:

  • the stated policies and objectives for the portfolio and the operation of those policies in practice. These include whether management's strategy focuses on earning contractual interest income, maintaining a particular interest rate profile, matching the duration of the financial assets to the duration of any related liabilities or expected cash outflows or realizing cash flows through the sale of the assets;
  • how the performance of the portfolio is evaluated and reported to the Group's management;
  • the risks that affect the performance of the business model (and the financial assets held within that business model) and how those risks are managed;
  • how managers of the business are compensated e.g. whether compensation is based on the fair value of the assets managed or the contractual cash flows collected; and
  • the frequency, volume and timing of sales of financial assets in prior periods, the reasons for such sales and expectations about future sales activity.

Transfers of financial assets to third parties in transactions that do not qualify for derecognition are not considered sales.

Financial assets that are managed and whose performance is evaluated on a fair value basis are measured at FVTPL.

ii. Classification and subsequent measurement (continued)

Financial assets: Assessment whether contractual cash flows are solely payments of principal and interest

'Principal' is defined as the fair value of the financial asset on initial recognition. 'Interest' is defined as consideration for the time value of money and for the credit risk associated with the principal amount outstanding during a particular period of time and for other basic lending risks and costs (e.g. liquidity risk and administrative costs), as well as a profit margin.

Financial assets: Assessment whether contractual cash flows are solely payments of principal and interest (continued)

In assessing whether the contractual cash flows are solely payments of principal and interest, the Group considers the contractual terms of the instrument. This includes assessing whether the financial asset contains a contractual term that could change the timing or amount of contractual cash flows such that it would not meet this condition. In making this assessment, the Group considers:

  • contingent events that would change the amount or timing of cash flows;
  • terms that may adjust the contractual coupon rate, including variable rate features;
  • prepayment and extension features; and
  • terms that limit the Group's claim to cash flows from specified assets (e.g. non-recourse features).

A prepayment feature is consistent with the solely payments of principal and interest criterion if the prepayment amount substantially represents unpaid amounts of principal and interest on the principal amount outstanding, which may include reasonable additional compensation for early termination of the contract. Additionally, for a financial asset acquired at a significant discount or premium to its contractual par amount, a feature that permits or requires prepayment at an amount that substantially represents the contractual par amount plus accrued (but unpaid) contractual interest (which may also include reasonable additional compensation for early termination) is treated as consistent with this criterion if the fair value of the prepayment feature is insignificant at initial recognition.

Trade receivables and other receivables meet solely payments of principal and interest test since principal is the present value of the expected cash flows. Those receivables are managed in line with the held to collect business model.

Financial assets: Subsequent measurement and gains and losses

Financial assets at FVTPL are comprised of derivatives. These assets are
Financial assets at subsequently measured at fair value. Net gains and losses, including any interest, are
FVTPL recognized in profit or loss.
Financial assets at
amortized cost
Financial assets at amortized cost are comprised of cash and cash equivalents, trade
receivables, other receivables and other assets. These assets are subsequently
measured at amortized cost using the effective interest method. The amortized cost
is reduced by impairment losses. Interest income, foreign exchange gains and losses
and impairment are recognized in profit or loss. Any gain or loss on de-recognition
is recognized in profit or loss.
Equity investments
at FVOCI
Equity investments at FVOCI
include the Group's 6,84% of share of
Cetel. These
assets are subsequently measured at fair value. Dividends are recognized as income
in profit or loss unless the dividend clearly represents a recovery of part of the cost
of the investment. Other net gains and losses are recognized in OCI and are never
reclassified to profit or loss.

Cash and cash equivalents

Cash and cash equivalents include cash held in cash, deposits held in banks and other liquid investments with maturities of 3 months or less. Cash and cash equivalents used in the reporting of cash flows comprise cash and cash equivalents with a maturity of less than 3 months, excluding accrued interest income and blocked deposits. The Group calculates impairment by using the expected credit loss model in cases where cash and cash equivalents are not impaired for a certain reason. The expected credit loss calculation considers the past experiences of credit losses as well as the Group's forecasts for the future.

Financial liabilities: Classification, subsequent measurement and gains and losses

Financial liabilities are classified as measured at amortized cost or FVTPL. A financial liability is classified as at FVTPL if it is classified as held-for-trading, it is a derivative or it is designated as such on initial recognition. Financial liabilities at FVTPL are measured at fair value and net gains and losses, including any interest expense, are recognized in profit or loss. The Group does not have any financial liabilities at FVTPL except for derivatives and issued debt instruments.

Other financial liabilities are subsequently measured at amortized cost using the effective interest method. Interest expense and foreign exchange gains and losses are recognized in profit or loss. Any gain or loss on derecognition is also recognized in profit or loss.

Non-derivative financial liabilities

The Group initially recognized debt securities issued and subordinated liabilities on the date that they were originated. All other financial liabilities were recognized initially on the trade date, which was the date that the Group becomes a party to the contractual provisions of the instrument.

The Group classified non-derivative financial liabilities into the other financial liabilities category except for issued debt instruments. Such financial liabilities were recognized initially at fair value less any directly attributable transaction costs. Subsequent to initial recognition, these financial liabilities were measured at amortized cost using the effective interest method.

Non-derivative financial liabilities (continued)

Other financial liabilities were comprised of loans, trade and other payables, payables to related parties and other payables.

The amount of change in the fair value of the issued debt instruments at FVTPL that is attributable to changes in the credit risk of that liability is recognized in other comprehensive income and the remaining amount of change in the fair value is recognized in profit or loss.

Trade payables were payables to third parties in relation to their capacity as suppliers. Payables stemming from transactions with parties that were not suppliers or customers which were not classified as trade payables and were not a result of financing operations were recognized as other payables.

When a financial instrument gave rise to a contractual obligation on the part of the Group to deliver cash or another financial asset or to exchange another financial instrument under conditions that were potentially unfavourable, it was classified as a financial liability. The instrument was equity instrument if, the following were met:

a) The instrument included no contractual obligation to deliver cash or another financial asset to another entity; or to exchange financial assets or financial liabilities with another entity under conditions that were potentially unfavourableto the Group.

b) If the instrument would or might be settled in the Group's own equity instruments, it was a nonderivative that included no contractual obligation for the Group to deliver a variable number of its own equity instruments; or a derivative that would be settled only by the Group exchanging a fixed amount of cash or another financial asset for a fixed number of its own equity instruments.

Borrowing Costs

If financing costs arising from the loans are associated with acquisition or construction of qualifying assets, they are included in cost value of qualifying assets. Qualifying assets refer to assets which require a long time to be available for use or sales as intended. Other borrowing costs are accounted in statement of profit or loss in the period they occur.

iii. Derecognition

Financial assets

The Group derecognized a financial asset when the contractual rights to the cash flows from the asset expired, or it transferred the rights to receive the contractual cash flows in a transaction in which substantially all the risks and rewards of ownership of the financial asset were transferred. Any interest in such transferred financial assets that was created or retained by the Group was recognized as a separate asset or liability.

Financial liabilities

The Group derecognizes a financial liability when its contractual obligations are discharged or cancelled, or expired. The Group also derecognizes a financial liability when its terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value.

On derecognition of a financial liability, the difference between the carrying amount extinguished and the consideration paid (including any non-cash assets transferred or liabilities assumed) is recognized in profit or loss.

iv. Offsetting

Financial assets and financial liabilities are offset and the net amount presented in the statement of financial position when, and only when, the Group currently has a legally enforceable right to set off the amounts and it intends either to settle them on a net basis or to realize the asset and settle the liability simultaneously.

v. Impairment

Financial instruments and contract assets

The Group recognizes loss allowances for ECLs on:

  • financial assets measured at amortized cost;
  • contract assets (as defined in TFRS 15).

Under TFRS 9, loss allowances are measured on either of the following bases:

  • Lifetime ECLs are the ECLs that result from all possible default events over the expected life of a financial instrument; and
  • 12-month ECLs are the portion of ECLs that result from default events that are possible within the 12 months after the reporting date (or a shorter period if the expected life of the instrument is less than 12 months).

The Group measures loss allowances at an amount equal to lifetime ECL, except for the following, which are measured as 12-month ECL:

bank balances for which credit risk has not increased significantly since initial recognition.

Loss allowances for trade receivables, other receivables, other assets and contract assets are always measured at an amount equal to lifetime ECL.

When determining whether the credit risk of a financial asset has increased significantly since initial recognition and when estimating ECL, the Group considers reasonable and supportable information that is relevant and available without undue cost or effort. This includes both quantitative and qualitative information and analysis, based on the Group's historical experience and informed credit assessment and including forward-looking information.

The Group assumes that the credit risk on a financial asset has increased significantly if it is more than 30 days past due.

v. Impairment (continued)

Financial instruments and contract assets (continued)

The Group considers a financial asset to be in default when:

  • the borrower is unlikely to pay its credit obligations to the Group in full, without recourse by the Group to actions such as realizing security (if any is held); or
  • the financial asset is more than 90 days past due.

The Group considers bank balances to have low credit risk when its credit risk rating is equivalent to the globally understood definition of 'investment grade'.

The maximum period considered when estimating ECLs is the maximum contractual period over which the Group is exposed to credit risk.

12-month expected credit losses are that result from possible default events within the 12 months after the reporting date.

The maximum period considered when estimating expected credit losses is the maximum contractual period over which the Group is exposed to credit risk.

Measurement of ECLs

ECLs are a probability-weighted estimate of credit losses. Credit losses are measured as the present value of all cash shortfalls.

ECLs are discounted at the effective interest rate of the financial asset.

For trade receivables, other receivables, other assets and contract assets the Group applies the simplified approach to providing for expected credit losses prescribed in TFRS 9, which requires the use of the lifetime expected loss provision for all trade receivables. The Group performed the calculation of ECL rates separately for individual, corporate, public and wholesale customers. The ECLs were calculated based on actual credit loss experience over the past years.

Exposures within each group were segmented based on common credit risk characteristics such as delinquency status.

Actual credit loss experience was adjusted to reflect differences between economic conditions during the period over which the historical data was collected, current conditions and the Group's view of economic conditions over the expected lives of the receivables. Future collection performance of receivables are estimated by considering general economic conditions to incorporate forward looking information to the expected credit loss calculations.

Credit-impaired financial assets

At each reporting date, the Group assesses whether financial assets carried at amortized cost are credit-impaired. A financial asset is 'credit-impaired' when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred.

a) Financial instruments (continued)

v. Impairment (continued)

Evidence that a financial asset is credit-impaired includes the following observable data:

  • significant financial difficulty of the borrower or issuer;
  • a breach of contract such as a default or being more than 90 days past due;
  • the restructuring of a loan or advance by the Group on terms that the Group would not consider otherwise;
  • it is probable that the borrower will enter bankruptcy or other financial re-organization; or
  • the disappearance of an active market for a security because of financial difficulties.

Presentation of impairment in the statement of financial position

Loss allowances for financial assets measured at amortized cost are deducted from the gross carrying amount of the assets.

Impairment losses related to trade and other receivables, including contract assets, are presented separately in the statement of profit or loss. Impairment losses on other financial assets are presented under 'general administrative expenses', similar to the presentation under TAS 39, and not presented separately in the consolidated statement of profit or loss due to materiality considerations.

Write-off

The gross carrying amount of a financial asset is written off (either partially or in full) to the extent that there is no realistic prospect of recovery. This is generally the case when the Group determines that the debtor does not have assets or sources of income that could generate sufficient cash flows to repay the amounts subject to the write-off. However, financial assets that are written off could still be subject to enforcement activities in order to comply with the Group's procedures for recovery of amounts due.

Financial assets are written off when there is no reasonable expectation of recovery, such as a debtor failing to engage in a repayment plan with the Group. Where trade receivables, other receivables, other assets and contract assets have been written off, the Group continues to engage in enforcement activity to attempt to recover the receivable due. Where recoveries are made, these are recognized in profit or loss.

vi. Derivative financial instruments

Cash flow hedges

The Group has adopted TFRS 9 Financial Instruments, replacing TAS 39 in accordance with the risk management strategy and objectives as of 1 July 2018. The high-level aim of the new hedge accounting model is that financial reporting will reflect more accurately how an entity manages its risk and the extent to which hedging mitigates those risks. Specifically, the new model aims to provide a better link between an entity's risk management strategy, the rationale for hedging and the impact of hedging on the financial statements.

vi. Derivative financial instruments (continued)

Cash flow hedges (continued)

The Group enters into participating cross currency swap transactions in order to hedge the changes in cash flows of floating and fixed rate financial instruments. While applying cash flow hedge accounting, the effective portion of the changes in the fair value of the hedging instrument is accounted for under "other comprehensive income/expense items to be reclassified to profit or loss" in equity, and the ineffective portion is recognized in profit or loss. The changes recognized in equity is removed and included in profit or loss in the same period when the hedged cash flows effect the profit or loss. In addition, time value of options included in participating cross currency swaps are accounted for cost of hedging and recognized under other comprehensive income. Cash flow hedge gains/(losses) and the effects of inflation accounting on the time value changes of options are transferred to retained earnings when the cash flow hedge is discontinued. Cash flow hedge losses and gains are reclassified to the income statement as the hedged item is realized.

Under IFRS 9, a hedging relationship is discontinued in its entirety when as a whole it ceases to meet the qualifying criteria after considering the rebalancing of the hedging relationship. Voluntary discontinuation when the qualifying criteria are met is prohibited. Hedge accounting is discontinued when the risk management objective for the hedging relationship has changed, the hedging instrument expires or is sold, terminated or exercised, and there is no longer an economic relationship between the hedged item and hedging instrument or when the effect of credit risk starts dominating the value changes that result from the economic relationship.

When the Group discontinues hedge accounting for a cash flow hedge it shall account for the amount that has been accumulated in the cash flow hedge reserve in accordance as follows;

-if the hedged future cash flows are still expected to occur, that amount shall remain in the cash flow hedge reserve until the future cash flows occur.

-if the hedged future cash flows are no longer expected to occur, that amount shall be immediately reclassified from the cash flow hedge reserve to profit or loss as a reclassification adjustment. A hedged future cash flow that is no longer highly probable to occur may still be expected to occur. The amount recognized in OCI prior discontinuation will be reclassified from OCI to Profit and Loss, in accordance with the contractual cash flow of the hedged item.

The new hedge effectiveness testing model is prospective only and can be qualitative, depending on the complexity of the hedge. Effectiveness range 80%-125% in TAS 39 is replaced by an objectivesbased test that focuses on the economic relationship between the hedged item and the hedging instrument, and the effect of credit risk on that economic relation.

b) Property, plant and equipment

i) Recognition and measurement

Property, plant and equipment ("PPE") of the Group other than lands is carried at cost less accumulated depreciation and any accumulated impairment losses. The Group elected to measure property, plant and equipment of the Company on a deemed cost basis in the first period of application of TAS 29 "Financial Reporting in Hyper Inflationary Economy" since detailed records of the acquisition date and costs of items of PPE were not available for the Company prior to 1 January 2000.

The deemed cost values for buildings as at 1 January 2000 were appraised by CMB licensed realestate valuation companies. The network equipment and vehicles values were appraised by Detecon International GmbH (a subsidiary of Deutsche Telecom AG). Other than the PPE for which cost was determined on a deemed cost basis, the cost of PPE generally comprises its purchase price, including import duties and non-refundable purchase taxes and any directly attributable costs of bringing the asset to its working condition and location for its intended use. PPE that are recognized at deemed cost basis or at cost are restated for the effects of inflation in accordance with TAS 29.

Lands accounted as property, plant and equipment are measured at revalued amount. Revalued amount for lands is the fair value at the date of the revaluation less any subsequent accumulated depreciation and subsequent accumulated impairment losses.

Cost includes expenditure that is directly attributable to the acquisition of the asset. The cost of selfconstructed assets includes the cost of materials and direct labor costs are located and capitalized borrowing costs. Purchased software that is integral to the functionality of the related equipment is capitalized as part of that equipment. When parts of an item of property and equipment have different useful lives, they are accounted for as separate items (major components) of property and equipment.

Gains and losses on disposal of an item of property and equipment are calculated as the difference between the net proceeds from disposal and the carrying amount of the item and are recognized net within "income / (expense) from investing activities" in profit or loss.

ii) Subsequent cost

The cost of replacing part of an item of property and equipment is recognized in the carrying amount of the item if it is probable that the future economic benefits embodied within the part will flow to the Group and its cost can be measured reliably. The carrying amount of the replaced part is derecognized. The costs of the day-to-day servicing of property and equipment are recognized in consolidated statement of profit / (loss) as incurred.

iii) Depreciation

Depreciation is calculated effective from purchase or replacement date to write off the cost of items of property, plant and equipment less their estimated residual values using the straight-line basis over their estimated useful lives. Land is not depreciated.

b) Property, plant and equipment (continued)

iii)Depreciation (continued)

Useful lives of property, plant and equipment are as follows:

Property plant and equipment Useful life (years)
Buildings 21-50 years
Outside plant 5-21 years
Transmission equipment 5-21 years
Switching equipment 5-8 years
Data networks 3-10 years
Vehicles 5 years
Furniture and fixtures 3-5 years
Set-top box and satellite receiver 4 years
Other property, plant and equipment 2-8 years

Useful lives and residual values are reviewed at each reporting date and adjusted if appropriate.

The useful lives of the Company's tangible assets are limited to the duration of the concession agreement, except for those that are outside the scope of the concession agreement. The Group has made changes to the remaining useful lives of the tangible and intangible assets within the scope of the concession as of 1 January 2024, after receiving confirmation from the relevant authority regarding their compliance with accounting standards, due to the concrete progress made in the negotiations with official institutions regarding the extension of the fixed line concession agreement. Accordingly, the remaining life of the Company's tangible and intangible assets is at most 25,2 years, excluding those outside the scope of the concession agreement.

Leased assets are depreciated by the same method used for property and equipment over the shorter of the lease term and their useful lives.

c) Intangible assets

i) Goodwill

Goodwill that arises on the acquisition of subsidiaries is included in intangible assets.

The Group measures goodwill at the acquisition date as:

  • a) The fair value of the consideration transferred; plus
  • b) The recognized amount of any non-controlling interests in the acquiree; plus
  • c) If the business combination is achieved in stages, the fair value of the pre-existing equity interest in the acquiree; less
  • d) The net recognized amount (generally fair value) of the identifiable assets acquired and liabilities assumed.

When the excess is negative, a bargain purchase gain is recognized immediately in profit or loss. The consideration transferred does not include amounts related to the settlement of pre-existing relationships. Such amounts are generally recognized in profit or loss. Transactions costs, other than those associated with the issuance of debt or equity securities, that the Group incurs in connection with a business combination are expensed as incurred.

Subsequent measurement

Goodwill is measured at cost less accumulated impairment losses.

2. BASIS OF PRESENTATION OF FINANCIAL STATEMENTS (CONTINUED)

2.3 Significant accounting policies (continued)

c) Intangible assets (continued)

ii) Other intangible assets

Intangible assets acquired separately are measured on initial recognition at cost. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and any accumulated impairment losses. Internally generated intangible assets, excluding capitalized development costs, are not capitalized and expenditure is charged to the consolidated income statement during the year when the expenditure is incurred.

The useful lives of intangible assets are assessed to be either finite or infinite. The Group does not have any intangible assets with infinite useful lives. Intangible assets with finite lives are amortized on a straight line basis over the shorter of their useful economic lives or remaining concession period. Whenever there is an indication that the intangible asset may be impaired it is assessed for impairment. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed each financial year end at least.

The Group has recognized the sum of the cost of the investments required for the telecommunication service that it is obliged to perform under the concession agreement and the comparable profit margin applied to construction services and infrastructure investments of the same quality as the amount of the investments as intangible assets in accordance with IFRS Interpretation 12 "Concession Service Agreements" ("IFRS Interpretation 12") and recognized as "Concession Rights and Assets" in the consolidated financial statements.

Changes in the expected useful lives or the expected pattern of consumption of future economic benefits embodied in the asset are accounted for by changing the amortization period or method, as appropriate, and treated as changes in estimates. The amortization expense on intangible assets with finite lives is recognized in the consolidated income statement. The amortization periods for intangible assets are between 3 and 25 years. The useful lives of the Company's tangible assets are limited to the duration of the concession agreement, except for those that are outside the scope of the concession agreement. The Group has made changes to the remaining useful lives of the tangible and intangible assets within the scope of the concession as of 1 January 2024, after receiving confirmation from the relevant authority regarding their compliance with accounting standards, due to the concrete progress made in the negotiations with official institutions regarding the extension of the fixed line concession agreement. Accordingly, the remaining life of the Company's tangible and intangible assets is at most 25,2 years, excluding those outside the scope of the concession agreement.

iii) Research and development

Research costs are expensed as incurred. Development expenditure on an individual project is recognized as an intangible asset when the Group can demonstrate the technical feasibility of completing the intangible asset so that it will be available for use or sale, its intention to complete and its ability to use or sell the asset, how the asset will generate future economic benefits, the availability of resources to complete the asset and the ability to measure reliably the expenditure during development.

c) Intangible assets (continued)

iii) Research and development (continued)

Impairment test is performed periodically in order to identify whether there is any impairment in the development stage. After initial recognition, development costs are recognized at cost less amortization and impairment. Amortization of the asset begins when development is complete and the asset is available for use. It is amortized over the period of expected future benefit. Periodic impairment tests are applied to the assets in order to foresee any probable impairment on the assets in the period that they are not ready for utilization yet.

iv) TV contents

Rights to feature contents such as films, TV shows etc. acquired under license agreements along with related obligations are recorded at the contract value when a license agreement is executed or the license period has begun. The amounts recognized are amortized on the licensing period or a per play basis over the licensing period. To the extent that it is determined that the content has no future programming usefulness and will no longer be exploited, the unamortized cost of the content is written off.

d) Investment properties

Investment properties, which are properties held to earn rent and/or for capital appreciation are measured initially at cost plus all direct transaction costs. The carrying amount includes the cost of replacing part of an existing investment property at the time that cost is incurred if the recognition criteria are met; and excludes the costs of day-to-day servicing of an investment property. The Group decided to measure investment property on a deemed cost basis in the first period of application of TAS 29, since detailed records of the acquisition date and costs of items of investment property were not available prior to 1 January 2000 and restated these deemed cost basis for the effects of inflation.

Investment properties are transferred from/to property, plant and equipment when their utilization purpose is changed. When investment properties are disposed, the difference between sales revenue and the carrying amount is charged to the consolidated income statement.

Market values of the investment properties at 1 January 2000 were determined by CMB licensed independent real-estate appraisers. Following initial recognition, investment properties are carried at costs less any accumulated amortization and any accumulated impairment losses.

Depreciation is charged to investment properties excluding land, over their estimated useful economic lives, using the straight-line method. The useful lives of buildings that are owned by the Group range between 15 - 50 years. The remaining useful life of the investment property is limited by the concession agreement, except for the exception of the concession agreement. When considering the Concession agreement the remaining useful lives of investment property is 25,2 years at the most.

2. BASIS OF PRESENTATION OF FINANCIAL STATEMENTS (CONTINUED)

2.3 Significant accounting policies (continued)

e) Assets held for sale

The Group classifies a non-current asset as held for sale if its carrying amount will be recovered principally through a sale transaction rather than through continuing use. For this to be the case, the asset (or the group of assets held for sale) must be available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets and its sale must be highly probable. For the sale to be highly probable management must be committed to a plan to sell the asset (or the group of assets held for sale) and an active program to set the buyers and complete the plan must have been initiated. Furthermore, the asset (or the group of assets held for sale) must be actively marketed for sale at a price that is reasonable in relation to its fair value. In addition, the sale should be expected to qualify for recognition as a completed sale within one year from the date of classification and actions required to complete the plan should indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.

In case the period to complete sale of assets is extended due to circumstances which are not under the control of the Group, the assets will continue to be classified as assets held for sale provided that the Group has still an active sales program.

The Group measures assets held for sale at the lower of its carrying amount and fair value less costs to sell. The Group does not depreciate a non-current asset when it is classified as held for sale and the gain or loss arising from the sale of the assets is classified at income / expense from investing activities accounts.

f) Leases

The Group has applied TFRS 16 using the modified retrospective approach and therefore the comparative information has not been restated and continues to be reported under TAS 17 and TFRS Interpretation 4.

g) Inventory

Inventories are recognized at the lower of cost and net realizable value. Costs comprise purchase cost and, where applicable and those overheads that have been incurred in bringing the inventories to their present location and condition. Cost is calculated using the weighted average method. Net realizable value is the less marketing, selling and other various expenses to be incurred in order to realize sale.

h) Impairment

Non-financial assets

Property, plant and equipment

At each balance sheet date, the Group assesses whether there is an indication that any of its PPE and intangible assets may be impaired. If such an indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss. Where it is not possible to estimate the recoverable amount of an individual asset, the Group estimates the recoverable amount of the cash-generating unit to which the asset belongs.

The recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money.

2. BASIS OF PRESENTATION OF FINANCIAL STATEMENTS (CONTINUED)

2.3 Significant accounting policies (continued)

h) Impairment (continued)

If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying amount, the carrying amount of the asset (cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognized in the consolidated income statement.

Where an impairment loss subsequently reverses, the carrying amount of the asset (cash-generating unit) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (cash-generating unit) in prior years. A reversal of an impairment loss is recognized immediately in the consolidated income statement.

Goodwill

Goodwill is reviewed for impairment, annually or more frequently if events or changes in circumstances indicate that the carrying value may be impaired. Whenever the carrying amount exceeds the recoverable amount, an impairment loss is recognized in the consolidated income statement. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of the cash-generating units or groups of cash-generating units that are expected to benefit from the synergies of the acquisition, irrespective of whether other assets or liabilities are assigned to these units or groups of units. Each unit or group of units to which the goodwill is allocated represents the lowest level within the Group at which the goodwill is monitored for internal management purposes. Impairment is determined by assessing the recoverable amount of the cash-generating unit (group of cash generating units), to which the goodwill relates.

Where the recoverable amount of the cash-generating unit (group of cash-generating units) is less than the carrying amounts of the net assets assigned to the cash-generating unit, an impairment loss is recognized. Impairment losses relating to goodwill cannot be reversed in future periods.

i) Reserve for employee severance indemnity

Payments to defined contribution retirement benefit plans are charged as an expense in the year in which the contributions relate to. Payments made to the Social Security Institution of Turkey and Turkish Republic Retirement Fund are dealt with as payments to defined contribution plans where the Group's obligations under the plans are equivalent to those arising in a defined contribution retirement benefit plan. The Group pays contributions to the Social Security Institution of Turkey on a mandatory basis.

The Group has no further payment obligations once the contributions have been paid. The contributions are recognized as an employee benefit expense in the period to which the employees' service relates.

For defined benefit plans and other long-term employment benefits, the cost of providing benefits is determined using the projected unit credit method, with actuarial valuations being carried out at each balance sheet date. The Company recognizes the service cost of the previous period as expense at the earlier of the dates below:

  • The date of the change or reduction in the plan, and
  • The date of the recognition of the related restructuring costs (see: TAS 37) or the benefits deriving from the termination of the employment contract,

2.3 Significant accounting policies (continued)

i) Reserve for employee severance indemnity (continued)

The retirement benefit obligation recognized in consolidated statement of financial position represents the present value of the defined benefit obligation as adjusted for any unrecognized past service cost. There is no funding requirement for defined benefit plans. The Group recognizes actuarial gains and losses in the other comprehensive income.

j) Provisions

Provisions are recognized when the Group has a present obligation as a result of a past event, and it is probable that an outflow of resources embodying economic benefits will be required to settle that obligation, and a reliable estimate can be made of the amount of the obligation.

Provisions are measured at the management's best estimate of the expenditure required to settle the obligation at the balance sheet date and are discounted to present value where the effect is material.

k) Contingent assets and liabilities

Possible assets or obligations that arise from past events and for which their existence will be confirmed only by the occurrence or non-occurrence of one or more uncertain future events not entirely within the control of the Group are treated as contingent assets or liabilities. A contingent liability is disclosed, unless the possibility of an outflow of resources embodying economic benefits is remote. If the possibility of transfer of assets is probable, contingent liability is recognized in the financial statements.

A contingent asset is disclosed in consolidated financial statements, when the possibility of an inflow of economic benefits to the entity is probable. If it has become virtually certain that an inflow of economic benefits will arise, the asset and the related income are recognized in the financial statements of the period in which the change occurs.

l) Related parties

a) Parties are considered related to the Company if a person or a close member of that person's family is related to a reporting entity;

if that person:

  • Has control or joint control over the reporting entity;
  • Has significant influence over the reporting entity; or
  • Is a member of the key management personnel of the reporting entity or of a parent of the reporting entity.

b) The entity and the reporting entity are members of the same group.

  • The entity and the company are members of the same group.

  • One entity is an associate or joint venture of the other entity (or an associate or joint venture of a member of a group of which the other entity is a member).

  • Both entities are joint ventures of the same third party.

  • One entity is a joint venture of a third entity and the other entity is an associate of the third entity.

  • The entity is controlled or jointly controlled by a person identified in (a).

  • A person identified in (a) (i) has significant influence over the entity or is a member of the key management personnel of the entity (or of a parent of the entity).

m)Revenue

Revenue is measured based on the consideration specified in a contract with a customer and excludes amounts collected on behalf of third parties. The Group recognizes revenue when it transfers control over a product or service to a customer.

i) Fixed line revenues

Revenues from fixed-line telecommunication services like network access, local usage, domestic and international long distance and infrastructure leases are recognized on an accrual basis as services are provided.

Connection fees that are assessed as distinct are recognized as revenue. Connection fees for activities that are an improvement to or an extension of the Group's own network, rather than a transfer of goods or services to the customer are determined as not distinct and no separate revenue is recognized.

For distinct connection fees in a bundle, revenue recognized is measured based on their stand-alone selling prices. The stand-alone selling prices of connection fees are estimated based on expected cost plus a margin approach.

Distinct connection fees are immediately recognized as revenue when connection services are provided and the cost of connection is also recognized immediately as an expense.

Revenues from sale of indefeasible right of use contracts, which are long term capacity/line rental arrangements, are accounted over the term of the contract.

ii) Mobile revenues

Revenues generated from mobile telecommunication services such as outgoing and incoming traffic, roaming revenues, revenues from value added services and monthly fees which are recognized at the time services are rendered. With respect to prepaid outgoing revenues, the Group generally collects cash in advance by selling scratch cards to dealers and distributors. In such cases, the Group does not recognize revenues until the subscribers use the service and present such amounts under deferred revenues in the consolidated financial statements.

The Group recognizes content revenue based on the agreement between the Group and the content providers. As the Group is the primary obligor of the service, the revenue received from the subscribers is presented on gross basis and the portion paid to the content providers is recognized as operating expense.

m)Revenue (continued)

iii) Equipment sale revenues

Revenues from sales of phone device, modem and other network equipment are recorded as revenue when control over a product or service is transferred to a customer.

For bundled packages, the Group accounts for individual products and services separately if they are distinct – i.e. if a product or service is separately identifiable from other items in the bundled package and if a customer can benefit from it either on its own or together with other resources that are readily available to the customer. The consideration is allocated between distinct products and services in a bundle based on their stand-alone selling prices. The stand-alone selling prices are determined based on the list prices at which the Group sells those products and services separately. For items that are not sold separately the Group estimates stand-alone selling prices using the expected cost plus a margin approach. Equipment revenues are presented in other revenues. Cost of products and services are recognized as expense when related revenue is recognized.

iv) TV revenues

Revenues from TV subscriptions are charged to contract customers on a monthly basis. Revenues are invoiced and recorded as part of a periodic billing cycle, and are recognized as the services are provided. Pay-per-view revenue is recognized when the movie is rented. Advertising revenue is recognized as the commercials are aired.

v) Subscriber acquisition costs

Subscriber acquisition costs include commissions and premiums incurred for acquisition and retention of subscribers.

The Group capitalizes these commission and premiums as incremental costs of obtaining a contract with a customer and if they are expected to be recovered.

Subscriber acquisition costs are amortized consistently during the subscriber life cycle and subscriber retention costs are amortized consistently during the renewal period and amortization expense is recognized in marketing, sales and distribution expenses.

vi) Significant financing component

To estimate the transaction price in a contract, the Group adjusts the promised amount of consideration for the time value of money if that contract contains a significant financing component. Significant financing component exists if the timing of payments agreed to by the parties to the contract (either explicitly or implicitly) provides the customer or the Group with a significant benefit of financing the transfer of goods or services to the customer.

Indefeasible right of use ("IRU") contracts of the Group are adjusted for significant financing component. For bundled contracts where the control of equipment is transferred to the customer upfront but collection is made in instalments, no significant financing component is recognized based on materiality considerations.

n) Income from investing activities and expense from investing activities

Income from investing activities are comprised of incomes from scrap and property, plant and equipment sales. Expense from investing activities are comprised of loss on sales of property, plant and equipment sales.

o) Financial income and financial expenses

The Group's finance income and finance costs include:

  • interest income;
  • interest expense;
  • derivative transaction cost, bank charges and commissions and other transaction cost;
  • coupon payments of bond;
  • gains and losses on hedging instruments recognized in profit or loss;
  • foreign currency gains or losses on financial assets and financial liabilities.

Interest income or expense is recognized using the effective interest method.

The 'effective interest rate' is the rate that exactly discounts estimated future cash payments or receipts through the expected life of the financial instrument to:

  • the gross carrying amount of the financial asset; or
  • the amortized cost of the financial liability.

In calculating interest income and expense, the effective interest rate is applied to the gross carrying amount of the asset (when the asset is not credit-impaired) or to the amortized cost of the liability. However, for financial assets that have become credit-impaired subsequent to initial recognition, interest income is calculated by applying the effective interest rate to the amortized cost of the financial asset. If the asset is no longer credit-impaired, then the calculation of interest income reverts to the gross basis.

Borrowing costs that cannot be matched with acquisition, construction or production of an asset are recognized in profit or loss by using effective interest rate.

Rediscount, interest and foreign exchange gains and losses arising from trading transactions are recognized in other operating income and expense.

Accounting for significant financing component is disclosed in detail in Note 2.4.(m).

p) Earnings per share

Earnings per share is calculated by dividing the consolidated profit/(loss) for the period attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period.

r) Taxes

Income tax expense is comprised of current and deferred tax. Income tax expense is recognized in the consolidated statement of profit / (loss) except to the extent that it relates to a business combination or items recognized directly in equity or other comprehensive income.

2.3 Significant accounting policies (continued)

r) Taxes (continued)

i) Current tax

Current tax is comprised of the expected tax payable or receivable on the taxable income or loss for the year and any adjustment to tax payable or receivable in respect of previous years. It is measured using tax rates enacted or substantively enacted at the reporting date. Current tax also includes any tax arising from dividends. Prepaid corporation taxes and corporate tax liabilities are offset when they relate to income taxes levied by the same taxation authority.

Turkish tax legislation does not permit a parent company and its subsidiary to file a consolidated tax return. Therefore, provisions for taxes, as reflected in the consolidated financial statements, have been calculated on a separate-entity basis.

ii) Deferred tax

Deferred tax is recognized on temporary differences between the carrying amounts of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit and are accounted for using the liability method.

Deferred tax liabilities are generally recognized for all taxable temporary differences and deferred tax assets are recognized to the extent that it is probable that taxable profits will be available against which deductible temporary differences can be utilized.

Deferred tax is not recognized for• Temporary differences on the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit and loss;

• Temporary differences related to investments in subsidiaries, associates and joint arrangements to the extent that the Group's able to control the timing of the reversal of the temporary differences and it is probable that they will not reverse in the foreseeable future; and

• Taxable temporary differences arising on the initial recognition of goodwill.

The carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered.

The Company and the other consolidated subsidiaries have reflected their deferred tax asset and liabilities by netting their individual balances; however, there is no netting on a consolidation basis. Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset realized.

Deferred tax assets are recognized for unused tax loses, unused tax credits a deductible temporary differences to the extent that it is possible that future taxable profits will be available against which they can be used. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefit will be realized.

iii) Tax exposures

In determining the amount of current and deferred tax the Group takes into account the impact of uncertain tax positions and whether additional taxes and interest may be due. This assessment relies on estimates and assumptions and may involve a series of judgments about future events. New information may become available that causes the Group to change its judgment regarding the adequacy of existing tax liabilities; such changes to tax liabilities will impact tax expense in the period that such a determination is made.

The Group believes that its accruals for tax liabilities are adequate for all open tax years based on its assessment of many factors, including interpretations of tax law and prior experience.

s) Segment reporting

An operating segment is a component of the Group that engages in business activities from which it may earn revenues and incur expenses, including revenues and expenses that relate to transactions with any of the Group's other components. All operating segments' operating results are reviewed regularly by the Group's board of directors to make decisions about resources to be allocated to the segment and assess its performance, and for which discrete financial information is available.

t) Determination of fair values

A number of the Group's accounting policies and disclosures require the determination of fair value, for both financial and non-financial assets and liabilities. Fair values have been determined for measurement and/or disclosure purposes based on the following methods. When applicable, further information about the assumptions made in determining fair values is disclosed in the notes specific to that asset or liability.

i) Trade and other receivables

The fair value of trade and other receivables is estimated as the present value of future cash flows discounted at the market rate of interest at the reporting date. Short-term receivables with no stated interest rate are measured at the original invoice amount if the effect of discounting is immaterial. This fair value is determined at initial recognition and at the end of each reporting period for disclosure purposes.

ii) Derivatives

The fair value of interest rate swaps and forward exchange contracts are based on broker quotes. Those quotes are tested for reasonableness by discounting estimated future cash flows based on the terms and maturity of each contract and using market interest rates for a similar instrument at the measurement date. Fair values reflect the credit risk of the instrument and include adjustments to take account of the credit risk of the Group entity and counterparty when appropriate.

iii) Issued debt instruments

The fair values of issued debt instruments are measured by using quoted market price at the date of valuation.

iv) Other non-derivative financial liabilities

Other non-derivative financial liabilities are measured at fair value, at initial recognition and for disclosure purposes, at each annual reporting date. Fair value is calculated based on the present value of future principal and interest cash flows, discounted at the market rate of interest at the measurement date.

v) Lands

Lands accounted as property, plant and equipment are measured at revalued amount. Revalued amount for lands is the fair value at the date of the revaluation less any subsequent accumulated depreciation and subsequent accumulated impairment losses.

vi) Foreign currency protected TL Deposits

Foreign currency protected TL Deposits are a financial asset with cash flows that include principal and interest, but they also feature a derivative product, as these cash flows may change depending on the change in exchange rates. Therefore, Currency Foreign currency protected TL Deposits are considered as hybrid contracts and accounted as financial assets whose fair value is recognized in profit or loss in line with the directions of TFRS 9 regarding hybrid contracts. Changes in the fair value of foreign currency protected TL Deposits are accounted in the "Income/Expense from Investing Activities" Item in the Statement of Profit or Loss and Other Comprehensive Income.

The accounting policies adopted in preparation of the consolidated financial statements as of 31 December 2024 are consistent with those of the previous financial year, except for the adoption of new and amended TFRS and TFRS interpretations effective as of 1 January 2024 and thereafter. The effects of these standards and interpretations on the Group's financial position and performance have been disclosed in the related paragraphs.

i) The new standards, amendments and interpretations which are effective as at 1 January 2024 are as follows:

Amendments to TAS 1- Classification of Liabilities as Current and Non-Current Liabilities

In March 2020 and January 2023, POA issued amendments to TAS 1 to specify the requirements for classifying liabilities as current or non-current. According to the amendments made in January 2023 if an entity's right to defer settlement of a liability is subject to the entity complying with the required covenants at a date subsequent to the reporting period ("future covenants"), the entity has a right to defer settlement of the liability even if it does not comply with those covenants at the end of the reporting period. In addition, January 2023 amendments require an entity to provide disclosure when a liability arising from a loan agreement is classified as non-current and the entity's right to defer settlement is contingent on compliance with future covenants within twelve months. This disclosure must include information about the covenants and the related liabilities. The amendments clarify that the requirement for the right to exist at the end of the reporting period applies to covenants which the entity is required to comply with on or before the reporting date regardless of whether the lender tests for compliance at that date or at a later date. The amendments also clarified that the classification of a liability is unaffected by the likelihood that the entity will exercise its right to defer settlement of the liability for at least twelve months after the reporting period. The amendments must be applied retrospectively in accordance with TAS 8.

The amendments did not have a significant impact on the financial position or performance of the Group.

Amendments to TFRS 16 - Lease Liability in a Sale and Leaseback

In January 2023, POA issued amendments to TFRS 16. The amendments specify the requirements that a seller-lessee uses in measuring the lease liability arising in a sale and leaseback transaction, to ensure the seller-lessee does not recognise any amount of the gain or loss that relates to the right of use it retains. In applying requirements of TFRS 16 under "Subsequent measurement of the lease liability" heading after the commencement date in a sale and leaseback transaction, the seller lessee determines 'lease payments' or 'revised lease payments' in such a way that the seller-lessee would not recognise any amount of the gain or loss that relates to the right of use retained by the sellerlessee. The amendments do not prescribe specific measurement requirements for lease liabilities arising from a leaseback. The initial measurement of the lease liability arising from a leaseback may result in a seller-lessee determining 'lease payments' that are different from the general definition of lease payments in TFRS 16. The seller-lessee will need to develop and apply an accounting policy that results in information that is relevant and reliable in accordance with TAS 8. A seller-lessee applies the amendments retrospectively in accordance with TAS 8 to sale and leaseback transactions entered into after the date of initial application of TFRS 16.

The amendments did not have a significant impact on the financial position or performance of the Group.

i) The new standards, amendments and interpretations which are effective as at 1 January 2022 are as follows: (continued)

Amendments to TAS 7 and TFRS 7 - Disclosures: Supplier Finance Arrangements

The amendments issued by POA in September 2023 specify disclosure requirements to enhance the current requirements, which are intended to assist users of financial statements in understanding the effects of supplier finance arrangements on an entity's liabilities, cash flows and exposure to liquidity risk. Supplier finance arrangements are characterized by one or more finance providers offering to pay amounts an entity owes its suppliers and the entity agreeing to pay according to the terms and conditions of the arrangements at the same date as, or a date later than, suppliers are paid. The amendments require an entity to provide information about terms and conditions of those arrangements, quantitative information on liabilities related to those arrangements as at the beginning and end of the reporting period and the type and effect of non-cash changes in the carrying amounts of those liabilities. In the context of quantitative liquidity risk disclosures required by TFRS 7, supplier finance arrangements are also included as an example of other factors that might be relevant to disclose.

The amendments did not have a significant impact on the financial position or performance of the Group.

ii) Standards issued but not yet effective and not early adopted

Standards, interpretations and amendments to existing standards that are issued but not yet effective up to the date of issuance of the consolidated financial statements are as follows. The Group will make the necessary changes if not indicated otherwise, which will be affecting the consolidated financial statements and disclosures, when the new standards and interpretations become effective.

Amendments to TFRS 10 and TAS 28: Sale or Contribution of Assets between an Investor and its Associate or Joint Venture

In December 2017, POA postponed the effective date of this amendment indefinitely pending the outcome of its research project on the equity method of accounting. Early application of the amendments is still permitted.

The Group will wait until the final amendment to assess the impacts of the changes.

TFRS 17 - The new Standard for insurance contracts

POA issued TFRS 17 in February 2019, a comprehensive new accounting standard for insurance contracts covering recognition and measurement, presentation and disclosure. TFRS 17 model combines a current balance sheet measurement of insurance contract liabilities with the recognition of profit over the period that services are provided. The mandatory effective date of the Standard postponed to accounting periods beginning on or after 1 January 2026 with the announcement made by the POA.

The standard is not applicable for the Group and will not have an impact on the financial position or performance of the Group.

Amendments to TAS 21 - Lack of exchangeability

In May 2024, POA issued amendments to TAS 21. The amendments specify how an entity should assess whether a currency is exchangeable and how it should determine a spot exchange rate when exchangeability is lacking. When an entity estimates a spot exchange rate because a currency is not exchangeable into another currency, it discloses information that enables users of its financial statements to understand how the currency not being exchangeable into the other currency affects, or is expected to affect, the entity's financial performance, financial position and cash flows. The amendments will be effective for annual reporting periods beginning on or after 1 January 2025. Early adoption is permitted but will need to be disclosed. When applying the amendments, an entity cannot restate comparative information.

The amendments did not have a significant impact on the financial position or performance of the Group.

iii) The amendments which are effective immediately upon issuance

Amendments to TAS 12 - International Tax Reform – Pillar Two Model Rules

In September 2023, POA issued amendments to TAS 12, which introduce a mandatory exception in TAS 12 from recognizing and disclosing deferred tax assets and liabilities related to Pillar Two income taxes. The amendments clarify that TAS 12 applies to income taxes arising from tax laws enacted or substantively enacted to implement the Pillar Two Model Rules published by the Organization for Economic Cooperation and Development (OECD). The amendments also introduced targeted disclosure requirements for entities affected by the tax laws. The temporary exception from recognition and disclosure of information about deferred taxes and the requirement to disclose the application of the exception apply immediately and retrospectively upon issue of the amendments.

The amendments did not have a significant impact on the financial position or performance of the Group.

iv)The new amendments that are issued by the International Accounting Standards Board (IASB) but not issued by Public Oversight Authority (POA)

The following two amendments to IFRS 9 and IFRS 7 and Annual Improvements to IFRS Accounting Standards as well as IFRS 18 and IFRS 19 are issued by IASB but not yet adapted/issued by POA. Therefore, they do not constitute part of TFRS. The Group will make the necessary changes to its consolidated financial statements after the amendments and new Standard are issued and become effective under TFRS.

Amendments to IFRS 9 and IFRS 7 – Classification and measurement of financial instruments

In May 2024, IASB issued amendments to the classification and measurement of financial instruments (amendments to IFRS 9 and IFRS 7). The amendment clarifies that a financial liability is derecognised on the 'settlement date'. It also introduces an accounting policy option to derecognise financial liabilities that are settled through an electronic payment system before settlement date if certain conditions are met. The amendment also clarified how to assess the contractual cash flow characteristics of financial assets that include environmental, social and governance (ESG)-linked features and other similar contingent features as well as the treatment of non-recourse assets and contractually linked instruments. Additional disclosures in IFRS 7 for financial assets and liabilities with contractual terms that reference a contingent event (including those that are ESG-linked), and equity instruments classified at fair value through other comprehensive income are added with the amendment.

The Group does not expect a significant impact on the financial statements.

Annual Improvements to IFRS Accounting Standards – Volume 11

In July 2024, the IASB issued Annual Improvements to IFRS Accounting Standards – Volume 11, amending the followings:

  • IFRS 1 First-time Adoption of International Financial Reporting Standards – Hedge Accounting by a First-time Adopter: These amendments are intended to address potential confusion arising from an inconsistency between the wording in IFRS 1 and the requirements for hedge accounting in IFRS 9.

  • IFRS 7 Financial Instruments: Disclosures – Gain or Loss on Derecognition: The amendments update the language on unobservable inputs in the Standard and include a cross reference to IFRS 13.

  • IFRS 9 Financial Instruments – Lessee Derecognition of Lease Liabilities and Transaction Price: IFRS 9 has been amended to clarify that, when a lessee has determined that a lease liability has been extinguished in accordance with IFRS 9, the lessee is required to apply derecognition requirement of IFRS 9 and recognise any resulting gain or loss in profit or loss. IFRS 9 has been also amended to remove the reference to 'transaction price".

  • IFRS 10 Consolidated Financial Statements – Determination of a 'De Facto Agent': The amendments are intended to remove the inconsistencies between IFRS 10 paragraphs.

  • IAS 7 Statement of Cash Flows – Cost Method: The amendments remove the term of "cost method" following the prior deletion of the definition of 'cost method'.

The standard is not applicable for the Group and will not have an impact on the financial position or performance of the Group.

The Group does not expect a significant impact on the financial statements.

Amendments to IFRS 9 and IFRS 7 - Contracts Referencing Nature-dependent Electricity

In December 2024, the Board issued Contracts Referencing Nature-dependent Electricity (Amendments to IFRS 9 and IFRS 7). The amendment clarifies the application of the "own use" requirements and permits hedge accounting if these contracts are used as hedging instruments. The amendment also adds new disclosure requirements to enable investors to understand the effect of these contracts on a company's financial performance and cash flows.

The Group does not expect a significant impact on the financial statements.

IFRS 18 – The new Standard for Presentation and Disclosure in Financial Statements

In April 2024, IASB issued IFRS 18 which replaces IAS 1. IFRS 18 introduces new requirements on presentation within the statement of profit or loss, including specified totals and subtotals. IFRS 18 requires an entity to classify all income and expenses within its statement of profit or loss into one of five categories: operating; investing; financing; income taxes; and discontinued operations. It also requires disclosure of management-defined performance measures and includes new requirements for aggregation and disaggregation of financial information based on the identified 'roles' of the primary financial statements and the notes. In addition, there are consequential amendments to other accounting standards, such as IAS 7, IAS 8 and IAS 34.

Its impact on the group financial statements is being evaluated.

IFRS 19 – Subsidiaries without Public Accountability: Disclosures

In May 2024, IASB issued IFRS 19, which allows eligible entities to elect to apply reduced disclosure requirements while still applying the recognition, measurement and presentation requirements in other IFRS accounting standards. Unless otherwise specified, eligible entities that elect to apply IFRS 19 will not need to apply the disclosure requirements in other IFRS accounting standards. An entity that is a subsidiary, does not have public accountability and has a parent (either ultimate or intermediate) which prepares consolidated financial statements, available for public use, which comply with IFRS accounting standards may elect to apply IFRS 19.

It is not valid on the Group's financial statements.

2.4 Significant accounting assessments, estimates and assumptions

In the process of applying the Group's accounting policies, the management has made the following judgments that have the most significant effect on the amounts recognized in the consolidated financial statements (excluding those involving estimations).

i) Operating Lease Commitments – Group as Lessor: The Company has entered into a crossoccupation agreement with PTT. The Group has determined that it retains all the significant risks and rewards of ownership of its properties subject to the agreement which are leased out on operating leases.

ii) Income from Sales Campaign: Group makes sales campaigns with suppliers under which they bundle telecommunication services with equipment supplied by the suppliers. The Group management accounts bundled offers as an agent if the sale transaction satisfies the below conditions:

  • Group, has no inventory risk.
  • Group has no responsibility on technical qualifications of equipment delivered to customers and responsibility after sale belongs to supplier.
  • Group does not make any modification on the equipment.
  • Group earns either a fixed rate of commission or zero profit on the transaction.

iii) Prepaid Card Sales Agent - Principal Analysis: Since TT Mobil is primarily responsible for providing the service, has credit and inventory risk and determinant in setting prices; starting from April 2010, TT Mobil recognizes prepaid card incomes on a gross basis.

iv) Commission income: The Group renders intermediary collection services regarding handsets sold by the distributors at the Group exclusive sale channels. Accordingly, the arrangement with the customer includes both handset principal amount and GSM services. Total considerations have been collected from the customers with up to 24 month instalments via GSM bills where each benefit is clearly identifiable and separable. The Group does not recognize any revenues from the sale of handsets and acts as an agent since it has no control over price, nor risk on stock. However, the collection risk of handset principal amount is on the Group and the distributors collect this amount from the Group on monthly basis. Apart from the GSM revenues, since customer base and sales channels are made available to the distributors, the Group charges a commission to those distributors. This commission income is classified under other revenues and it is recognized when the handset is delivered to the customer.

v) Content Sales: Since TT Mobil is primarily responsible for providing the service, has credit and determinant in setting prices; TT Mobil recognizes content revenues on a gross basis.

vi) Liabilities within the scope of vendor financing: For capital expenditures, the Group carries out vendor financing with some of its suppliers in accordance with the agreements made with banks and those suppliers. Since the terms are not substantially different with the discounted present value of the cash flows under the new terms of the liabilities, the Group continues to classify those liabilities as trade payable.

2.4 Significant accounting assessments, estimates and assumptions (continued)

Key sources of estimation uncertainty

The key assumptions concerning the future, and other key sources of estimation uncertainty at the balance sheet date, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are discussed below.

The Group determines whether property, plant and equipment are impaired by estimating the recoverable amount of the assets whenever there is an indication of impairment. This requires an estimation of the value in use of the cash-generating units. Estimating the value in use requires the Group to make an estimate of the expected future cash flows from the cash-generating unit and also to choose a suitable discount rate in order to calculate the present value of those cash flows (Note 16).

The estimates used by the Group in the application of TFRS Interpretation 12 are as follows:

  • The Company assesses that approximately 30% of the foreseen network investments related to the replacement of the network equipment which are reclassified to intangible assets and which are then recognized in the financial statements as intangible assets are the contractual replacements as required by the concession agreement.

  • In accordance with TFRS Interpretation 12, the Company has determined the cost of the investments in intangible assets recognized under the scope of TFRS Interpretation 12 by adding the profit margin, which is applied in the market for similar construction services, to the cost of acquiring the related network equipment. The estimated profit margin used in construction services provided in exchange for concession right is 13% (31 December 2023: 13%) for the year ended as of 31 December 2024. The profit margin of property, plant and equipment accounted within the scope of TFRS Interpretation 12 amounting to TL 9.760.589 (31 December 2023: TL 10.047.103) (Note 20) is TL 1.112.546 for the year ended as of 31 December 2024 (31 December 2023: TL 1.155.862) (Note 3).

  • A deferred tax asset is recognized only to the extent that it is probable that a tax benefit will be realized in the future. If it is probable that a tax benefit will be realized, a deferred tax asset is recognized on unused tax losses, unused tax credits and other deductible temporary differences. With the expectation to recover certain part of its tax losses carried forward in Türk Telekom, TT Mobil; TTNET and TTINT group has recognized deferred tax assets on statutory tax losses available for offsetting with future statutory taxable profits. Every year, the Group re-assesses its tax loss carry forwards and if there is a material change in the deferred tax asset recognized in the consolidated financial statements, the deferred tax assets are also changed (Note 11).

2. BASIS OF PRESENTATION OF FINANCIAL STATEMENTS (CONTINUED)

2.4 Significant accounting assessments, estimates and assumptions (continued) Key sources of estimation uncertainty (continued)

  • Assumptions used in the impairment test of property, plant and equipment and intangible assets have been explained in Note 16.

For trade receivables, other receivables, other assets and contract assets the Group applies the simplified approach to providing for expected credit losses prescribed in TFRS 9, which requires the use of the lifetime expected loss provision for all trade receivables. The Group performed the calculation of ECL rates separately for individual, corporate, public and wholesale customers. The ECLs were calculated based on actual credit loss experience over the past years. Exposures within each group were segmented based on common credit risk characteristics such as delinquency status. Actual credit loss experience was adjusted to reflect differences between economic conditions during the period over which the historical data was collected, current conditions and the Group's view of economic conditions over the expected lives of the receivables. Future collection performance of receivables is estimated by considering general economic conditions to incorporate forward looking information to the expected credit loss calculations.

Assumptions used by Company in goodwill impairment test are explained in Note 16. The Group determines the useful life of an asset by considering its future economic benefits. This evaluation is driven by the Group's previous experience on similar assets. The Group also considers useful life of the asset from technical and commercial perspectives due to changes and developments in market in order to assess whether additional impairment is required or not.

There are other estimations made by the management during the determination of provisions for litigations (Note 23).

3. SEGMENT REPORTING

The Group has two main segments; fixed line and mobile. Fixed line services are provided by Türk Telekom, TTNet, Argela, Innova, Sebit, AssisTT, TTES, TT Venture, TT Destek Hizmetleri and TTINT Group whereas mobile service is provided by TT Mobil. Group management assesses segment performance over earnings before interest, tax, depreciation and amortization ("Adjusted EBITDA"). Adjusted EBITDA is calculated by adjusting the profit before tax by i) adding income/expense from investing activities, depreciation, amortization and impairment expenses and ii) deducting exchange gains/losses, monetary gain and loss, interest and rediscount income/ expenses on current accounts presented in other operating income and expense. Group management uses adjusted EBITDA as it is comparable with other companies in the sector. EBITDA is not a measure of financial performance indicator defined in TFRS and may not be comparable to similar indicators defined by other companies. As Group management does not monitor Group's performance over geographical segments, geographical segment reporting is not presented. The segment results and balance sheet items are presented below:

As of 31 December 2024 deferred tax expense amounting to TL 734.453 (31 December 2023: TL 758.254 income) are recognized in the consolidated statement of other comprehensive income.

The Company and its subsidiaries located in Turkey are subject to taxation in accordance with the tax regulations and the legislation effective in Turkey where the Group companies operate. Corporate tax returns are required to be filed by the twenty-fifth day of the fourth month following the balance sheet date and taxes must be paid in one instalment by the end of the fourth month.

In Turkey, the corporate tax rate is 25% as of 31 December 2024. As of the three months period ended 31 December 2024, corporate tax provisions have been calculated and accrued at 25% (31 December 2023: 25%).

The tax legislation provides for a temporary tax of 25% to be calculated and paid based on earnings generated for first three quarters for the period ended 31 December 2024. The amounts thus calculated and paid are offset against the final corporate tax liability for the year.

In Turkey, the tax legislation does not permit a parent company and its subsidiaries to file a consolidated tax return. Therefore, provision for taxes, as reflected in the consolidated financial statements, has been calculated on a separate-entity basis.

Corporate tax losses can be carried forward for a maximum period of five years following the year in which the losses were incurred. The tax authorities can inspect tax returns and the related accounting records for a retrospective maximum period of five years.

Dividend payments made to resident and non-resident individuals, non-resident legal entities and corporations resident in Turkey (except for the ones exempt from corporate and income tax), are subject to an income tax of 15%.

Dividend payments made from a corporation resident in Turkey to a corporation also resident in Turkey are not subject to income tax. Furthermore, income tax is not calculated in case the profit is not distributed or transferred to equity.

The dividend income (excluding the participation certificates of investment funds and profit shares derived from the share certificates of investment trusts) derived by entities from the participation in the capital of another resident entity is exempt from corporate tax. Furthermore, 25% of the income derived by entities from the sale of participation shares and real estates (immovable property) preferential rights, founders' shares and redeemed shares which are carried in assets at least for two years is exempt from corporate tax as of 31 December 2024.

33. TAXATION ON INCOME (CONTINUED)

In order to be able to benefit from the exemption, the relevant income should be kept under a fund account in the liabilities and should not be withdrawn from the enterprise for 5 years. The sales amount should be collected by the end of the second calendar year following the year of sale.

The reconciliation between tax expense and the product of accounting profit multiplied by applicable tax is as follows:

Tax Advantages Obtained within the Scope of Investment Incentive System

Earnings of the Group that are derived from investments linked to an investment incentive certificate are subject to corporate tax at discounted rates for a certain period, which starts when the investment starts to partly or fully operate, and ends when the maximum investment contribution amount is reached. Within this scope, the Group has accounted for TL 2.559.795 (31 December 2023: TL 5.212.348) of tax advantages as deferred tax assets which are expected to be recovered in the foreseeable future in the consolidated financial statements as of 31 December 2024.

Deferred tax assets are recognized for deductible temporary differences, carry forward tax losses and indefinite-life investment incentives which allows payment of corporate tax at discounted rates, as long as it is probable that sufficient taxable income will be generated in the future. In this context, the Group recognizes deferred tax assets from investment incentives based on long-term plans, including taxable profit projections derived from business models, which are re-evaluated at each balance sheet date to assess recoverability of such deferred tax assets.

The Group expects to recover such deferred tax assets within 2 years from the balance sheet date. In the sensitivity analysis performed as of 31 December 2024, when the inputs of the key macroeconomic and sectoral assumptions that form the business plans are increased/decreased by 10%, there is no change in the projected 2-year recovery periods of deferred tax assets related to investment incentives.

34. FINANCIAL RISK MANAGEMENT OBJECTIVES AND POLICIES

All Group companies meet their cash needs determined in business plans approved by their boards, by using credits or capital increase with guidance of the central management. The Group may choose long or short term financing according to their financing needs and market assumptions.

The Group's risk management policies are designed to identify and analyze the risks faced by the Group, to determine appropriate risks limits and controls, and to observe commitment to these limits. Risk management policies and systems are constantly under review to reflect changes in the Group's activities and market conditions.

The Group audit committee oversees how management monitors compliance with the Group's risk management policies and procedures, and reviews the adequacy of the risk management framework in relation to the risks faced by the Group. The Group audit committee is assisted in its oversight role by internal audit.Internal audit undertakes both regular and ad hoc reviews of risk management controls and procedures, the results of which are reported to the audit committee.

Financial risk factors

The Group's principal financial instruments comprise forward market transactions, bank loans and cash and short-term deposits. The main purpose of these financial instruments is to raise funds for the Group's operations and to hedge interest rate risk. The Group has various other financial assets and liabilities such as trade receivables and trade payables, which arise directly from its operations. The main risks arising from the Group's financial instruments are cash flow interest rate risk, liquidity risk, foreign currency risk and credit risk. The board reviews and agrees to policies for managing each of these risks.

34. FINANCIAL RISK MANAGEMENT OBJECTIVES AND POLICIES (CONTINUED)

Credit risk (continued)

Financial losses due to Group's receivables and financial assets which result from not implementing agreement clauses related to financial assets by a customer or other party constitutes credit risk.

When determining the credit risk exposure as at the balance sheet date, items like guarantees received, which increase the credit worthiness have not been considered.

As of 31 December 2024, the maximum credit risk Company exposure is reflected by presenting all financial assets from carrying amount on consolidated balance sheet.

Liquidity risk

Liquidity risk is uncertainty to cover future financial obligations.

The Group's objective is to maintain a balance between current assets and liabilities through close monitoring of payment plans and cash projections.

The Group manages current and long-term funding by maintaining adequate reserves, banking facilities, reserve borrowing facilities and loan agreements with suppliers through continuously monitoring forecast and actual cash flows and matching the maturity profile of financial assets and liabilities.

34. FINANCIAL RISK MANAGEMENT OBJECTIVES AND POLICIES (CONTINUED)

Interest rate risk

The value of a financial instrument will fluctuate as a result of changes in market prices. The Group's interest rate risk is primarily attributable to its borrowings.

The interest-bearing financial liabilities have variable interest rates, whereas the interest bearing financial assets have a fixed interest rate and future cash flows associated with these financial instruments will not fluctuate in amount. The Group is subject to interest risk due to financial liabilities and finance lease obligations. Policy of the Group is to manage this risk through fixed and variable rates borrowings. In order to cover for these risks, the Group has entered into interest rate swaps (Note 15).

The interest rate risk table is presented below:

31 December 2024 31 December 2023
Financial instruments with fixed interest rate
Financial assets (*) 4.023.899 17.274.651
Financial liabilities (36.247.463) (57.024.515)
(32.223.564) (39.749.864)
Financial instruments with variable interest rate
Financial liabilities (30.120.917) (35.374.631
Effect of hedging 4.684.728 27.249.012
(25.436.189) (8.125.619)

(*) Financial assets consists of cash at banks - time deposit (Note 4).

If the base point of denominated interest rates for financial instruments with variable interest rate was higher 0,25%, with all other variables held constant, the Group's income before tax and minority interest would be lower by TL 11.961 (31 December 2023: TL 20.953) and interest rate was lower 0,25%, with all other variables held constant, the Group's income before tax and minority interest would be higher by TL 11.970 (31 December 2023: TL 21.049) as of 31 December 2024.

On the other side because of hedging, if the base point of interest rate higher/lower 0,25%, equity would have no effect (31 December 2023: would have no effect). If the base point of interest rate lower 0,25%, equity would have no effect (31 December 2023: would have no effect).

Explanation on the presentation of financial assets and liabilities at their fair values

The below table summarizes the carrying and fair values of financial asset and liabilities in the Group's consolidated financial statements.

Due to their short-term nature, the fair value of trade and other receivables represents their book value. The fair value of borrowings with fixed interests is obtained by calculating their discounted cash flows using the market interest rate effective at the reporting date. The fair value of foreign currency denominated borrowings with variable interests is obtained by discounting the projected cash flows using estimated market interest rates.
