Report on Review of Interim Financial Statements

(English Translation of a Report Originally Issued in Korean)

To the Shareholders and Board of Directors of

KT Corporation

Reviewed Financial Statements

We have reviewed the accompanying consolidated interim financial statements of KT Corporation and its subsidiaries (collectively referred to as the “Group”). These financial statements consist of the consolidated interim statement of financial position as at June 30, 2018, and the related consolidated interim statements of profit or loss, consolidated interim statements of comprehensive income for the three-month andsix-month periods ended June 30, 2018 and 2017, and consolidated interim statements of changes in equity and consolidated interim statements of cash flows for thesix-month periods ended June 30, 2018 and 2017, and a summary of significant accounting policies and other explanatory notes, expressed in Korean won.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated interim financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“Korean IFRS”) 1034Interim Financial Reporting, and for such internal control as management determines is necessary to enable the preparation of consolidated interim financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to issue a report on these consolidated interim financial statements based on our review.

We conducted our review in accordance with quarterly or semi-annual review standards established by the Securities and Futures Commission of the Republic of Korea. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Korean Standard on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe the accompanying consolidated interim financial statements do not present fairly, in all material respects, in accordance with Korean IFRS 1034Interim Financial Reporting.

Samil PricewaterhouseCoopers, 100, Hangangdaero, Yongsan-gu, Seoul 04386, Korea,www.samil.com

Other Matters

We have audited the consolidated statement of financial position of the Group as at December 31, 2017, and the related consolidated statements of profit or loss, comprehensive income, changes in equity and cash flows for the year then ended, in accordance with Korean Standards on Auditing. We expressed an unqualified opinion on those financial statements, not presented herein, in our audit report dated March 2, 2018. The consolidated statement of financial position as at December 31, 2017, presented herein for comparative purposes, is consistent, in all material respects, with the above audited statement of financial position as at December 31, 2017.

Review standards and their application in practice vary among countries. The procedures and practices used in the Republic of Korea to review such financial statements may differ from those generally accepted and applied in other countries.

August 14, 2018

This report is effective as of August 14, 2018, the review report date. Certain subsequent events or circumstances, which may occur between the review report date and the time of reading this report, could have a material impact on the accompanying interim consolidated financial statements and notes thereto. Accordingly, the readers of the review report should understand that there is a possibility that the above review report may have to be revised to reflect the impact of such subsequent events or circumstances, if any.

KT Corporation and Subsidiaries

Notes to the Consolidated Interim Financial Statements

June 30, 2018 and 2017 (Unaudited), and December 31, 2017

(1) New standards and amendments adopted by the Group

The Group newly applied the following amended and enacted standards and interpretations for the annual period beginning on January 1, 2018, and the application has following impacts on the consolidated interim financial statements.

• Korean IFRS 1115Revenue from Contracts with Customers

The Group has elected to apply Korean IFRS 1115Revenue from Contracts with Customers. In accordance with the transition provisions in Korean IFRS 1115, comparative figures have not restated. The Group elected the modified retrospective approach and recognized the cumulative impact of initially applying the revenue standard as an adjustment to retained earnings as at January 1 2018, the period of initial application. See Note 29 for further details on the impact of the application of the standard.

• Korean IFRS 1109Financial Instruments

The Group has applied Korean IFRS 1109Financial Instruments on January 1, 2018, the date of initial application. In accordance with the transitional provisions in Korean IFRS 1109, comparative figures have not been restated, and the differences between previous book amounts and book amounts at the date of initial application are recognized to retained earnings. See Note 29 for further details on the impact of the application of the standard.

• Amendments to Korean IFRS 1028Investments in Associates and Joint Ventures

When an investment in an associate or a joint venture is held by, or is held indirectly through, an entity that is a venture capital organization, or a mutual fund, unit trust and similar entities including investment-linked insurance funds, the entity may elect to measure that investment at fair value through profit or loss in accordance with Korean IFRS 1109. The amendments clarify that an entity shall make this election separately for each associate of joint venture, at initial recognition of the associate or joint venture. The Group does not expect the amendments to have a significant impact on the financial statements because the Group is not a venture capital organization

• Amendment to Korean IFRS 1040Transfers of Investment Property

Paragraph 57 of Korean IFRS 1040 clarifies that a transfer to, or from, investment property, including property under construction, can only be made if there has been a change in use that is supported by evidence, and provides a list of circumstances as examples. The Group does not expect the amendment to have a significant impact on the financial statements.

Notes to the Consolidated Interim Financial Statements

June 30, 2018 and 2017 (Unaudited), and December 31, 2017

• Amendments to Korean IFRS 1102Share-based Payment

Amendments to Korean IFRS 1102 clarify accounting for a modification to the terms and conditions of a share-based payment that changes the classification of the transaction from cash-settled to equity-settled. Amendments also clarify that the measurement approach should treat the terms and conditions of a cash-settled award in the same way as for an equity-settled award. The Group does not expect the amendments to have a significant impact on the financial statements.

• Enactment of Interpretation 2122Foreign Currency Transaction and Advance Consideration

According to the enactment, the date of the transaction for the purpose of determining the exchange rate to use on initial recognition of the related asset, expense or income (or part of it) is the date on which an entity initially recognizes thenon-monetary asset ornon-monetary liability arising from the payment or receipt of advance consideration. The Group does not expect the enactment to have a significant impact on the financial statements.

(2) New standards and interpretations not yet adopted by the Group

Certain new accounting standards and interpretations that have been published that are not mandatory for annual reporting period commencing January 1, 2018 and have not been early adopted by the Group are set out below.

• Enactment of Korean IFRS 1116Leases

Korean IFRS 1116Leases issued on May 22, 2017 is effective for annual periods beginning on or after January 1, 2019, with early adoption permitted. This standard will replace Korean IFRS 1017Leases. The Group will apply the standards for annual periods beginning on or after January 1, 2019.

Under the new standard, with implementation of a single lease model, lessee is required to recognize assets and liabilities for all lease which lease term is 12 months or more and underlying assets are not low value assets. A lessee is required to recognize aright-of-use asset and a lease liability representing its obligation to make lease payments.

The Group performed an impact assessment to identify potential financial effects of applying Korean IFRS 1116. The Group is analyzing the effects on the financial statements based on available information as at June 30, 2018 to identify effects on 2018 interim financial statements; however, it is difficult to provide reasonable estimates of financial effects until the analysis is complete.

2.2 Accounting Policies

Significant accounting policies and method of computation used in the presentation of the condensed consolidated interim financial statements are consistent with those of the consolidated financial statements for the year ended December 31, 2017, except for the changes due to the application of amendment and enactments of standards described in Note 2.1 the one described below.

2.2.1 Income Tax Expense

Income tax expense for the interim period is recognized based on management’s best estimate of the weighted average annual income tax rate expected for the full financial year. The estimated average annual tax rate is applied to thepre-tax income.

2.2.2 Financial Assets

(a) Classification

From January 1, 2018, the Group classifies its financial assets in the following measurement categories:

• those to be measured subsequently at fair value (either through other comprehensive income, or through profit or loss), and

• those to be measured at amortized cost

The classification depends on the entity’s business model for managing the financial assets and the contractual terms of the cash flows.

For financial assets measured at fair value, gains and losses will either be recorded in profit or loss or other comprehensive income. For investments in debt instruments, this will depend on the business model in which the investment is held. The Group reclassifies debt investments when and only when its business model for managing those assets changes.

For investments in equity instruments that are not held for trading, this will depend on whether the Group has made an irrevocable election at the time of initial recognition to account for the equity investment at fair value through other comprehensive income. Changes in fair value of the investments in equity instruments that are not accounted for as other comprehensive income are recognized in profit or loss.

(b) Measurement

At initial recognition, the Group measures a financial asset, in the case of a financial asset not at fair value through profit or loss, at its fair value plus transaction costs that are directly attributable to the acquisition of the financial asset or the issuance of the financial liabilities. Transaction costs of financial assets carried at fair value through profit or loss are expensed in profit and loss.

Hybrid (combined) contracts with embedded derivatives are considered in their entirety when determining whether their cash flows are solely payment of principal and interest.

Debt instruments

Subsequent measurement of debt instruments depends on the Group’s business model for managing the asset and the cash flow characteristics of the asset. The Group classifies its debt instruments into one of the following three measurement categories:

• Amortized cost: Assets that are held for collection of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortized cost. A gain or loss on a debt investment that is subsequently measured at amortized cost and is not part of a hedging relationship is recognized in profit or loss when the asset is derecognized or impaired. Interest income from these financial assets is included in ‘finance income’ using the effective interest rate method.

• Fair value through other comprehensive income: Assets that are held for collection of contractual cash flows and for selling the financial assets, where the assets’ cash flows represent solely payments of principal and interest, are measured at fair value through other comprehensive income. Movements in the carrying amount are taken through other comprehensive income, except for the recognition of impairment loss (and reversal of impairment loss), interest income and foreign exchange gains and losses which are recognized in profit or loss. When the financial asset is derecognized, the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to profit or loss. Interest income from these financial assets is included in ‘finance income’ using the effective interest rate method. Foreign exchange gains and losses are presented in ‘finance income or finance costs’ and impairment loss in ‘finance costs or operating expenses’.

• Fair value through profit or loss: Assets that do not meet the criteria for amortized cost or fair value through other comprehensive income are measured at fair value through profit or loss. A gain or loss on a debt investment that is subsequently measured at fair value through profit or loss and is not part of a hedging relationship is recognized in profit or loss and presented net in the statement of profit or loss within ‘finance income or finance costs’ in the period in which it arises.

Equity instruments

The Group subsequently measures all equity investments at fair value. Where the Group’s management has elected to present fair value gains and losses on equity investments in other comprehensive income, there is no subsequent reclassification of fair value gains and losses to profit or loss following the derecognition of the investment. Dividends from such investments continue to be recognized in profit or loss as ‘finance income’ when the Group’s right to receive payments is established.

Changes in the fair value of financial assets at fair value through profit or loss are recognized in ‘finance income or finance costs’ in the statement of profit or loss as applicable. Impairment loss (and reversal of impairment loss) on equity investments measured at fair value through other comprehensive income are not reported separately from other changes in fair value.

(c) Impairment

The Group assesses on a forward looking basis the expected credit losses associated with its debt instruments and contract assets carried at amortized cost and fair value through other comprehensive income. The impairment methodology applied depends on whether there has been a significant increase in credit risk. For trade receivables and contract assets, the Group applies the simplified approach, which requires expected lifetime losses to be recognized from initial recognition of the receivables.

(d) Derivative instruments and Hedging Activities

Derivatives are initially recognized at fair value on the date a derivative contract is entered into and are subsequently remeasured at their fair value at the end of each reporting period. Changes in the fair value of any derivative instrument that does not qualify for hedge accounting are recognized immediately in profit or loss. The accounting for subsequent changes in fair value depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged and the type of hedge relationship designated.

The Group designates their currency derivatives as hedges of foreign exchange risk associated with the cash flows of highly probable forecast transactions.

The Group documents at the inception of the hedging transaction the economic relationship between hedging instruments and hedged items including whether the hedging instrument is expected to offset changes in cash flows of hedged items. The Group documents its risk management objective and strategy for undertaking various hedge transactions at the inception of each hedge relationship.

The fair values of various derivative financial instruments used for hedging purposes are disclosed in Note 28.

The full fair value of a hedging derivative is classified as anon-current asset or liability when the remaining maturity of the hedged item is more than 12 months; it is classified as a current asset or liability when the remaining maturity of the hedged item is less than 12 months. Derivatives held for trading are classified as a current asset or liability.

The new accounting policies related to hedge accounting applied from January 1, 2018 are as follows:

21

KT Corporation and Subsidiaries

Notes to the Consolidated Interim Financial Statements

June 30, 2018 and 2017 (Unaudited), and December 31, 2017

• Cash flow hedges

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in the cash flow hedge reserve within equity, limited to the cumulative change in fair value (present value) of the hedged item (the present value of the cumulative change in the future expected cash flows of the hedged item) from the inception of the hedge. The ineffective portion is recognized in ‘finance income (costs)’.

Amounts accumulated in equity are reclassified in the periods when the hedged item affects profit or loss.

When a hedging instrument expires, or is sold, terminated, exercised, or when a hedge no longer meets the criteria for hedge accounting, any accumulated cash flow hedging reserve cumulative deferred gain or loss and deferred costs of hedging in equity at that time remains in equity until the forecast transaction occurs, resulting in the recognition of anon-financial asset such as inventory. When the forecast transaction is no longer expected to occur, the cumulative gain or loss and deferred costs of hedging that were reported in equity are immediately reclassified to profit or loss.

2.2.3 Revenue Recognition

From January 1, 2018, the Group has applied Korean IFRS 1115Revenue from Contracts with Customers.

(a) Identifying performance obligations

The Group provides telecommunication services and sells handsets as their main business. With the implementation of Korean IFRS 1115, the Group identifies performance obligations with a customer such as providing telecommunication services, selling handsets and others. The timing of revenue recognition depends on whether a performance obligation is satisfied at a point in time or over time. Where a performance obligation is satisfied over time, the related revenue is also recognized over time.

(b) Allocation the transaction price

With the implementation of Korean IFRS 1115, the Group allocates the transaction price to each performance obligation identified in the contract based on a relative stand-alone selling prices of the goods or services being provided to the customer. To allocate the transaction price to each performance obligation on a relative stand-alone price basis, the Group determines the stand-alone selling price at contract inception of the distinct goods or services underlying each performance obligation in the contract and allocate the transaction price in proportion to those stand-alone selling price. The stand-alone selling price is the price at which the Group would sell promised goods or services separately to the customer. The best evidence of a stand-alone selling price is the observable price of goods or services when the Group sells that goods or services separately in similar circumstances and to similar customers. The Group recognizes the allocated amount as contract assets or contract liabilities, and amortizes it through the remaining period which is adjusted in operating income.

Notes to the Consolidated Interim Financial Statements

June 30, 2018 and 2017 (Unaudited), and December 31, 2017

(c) Incremental costs of obtaining a contract

The Group pays the commission fees when new customer subscribe for telecommunication services. The incremental costs of obtaining a contract are those commission fees that the Group incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained.

According to Korean IFRS 1115, the Group recognizes as an asset the incremental cost of obtaining contract and amortize it through the contract period. However, as a practical expedient, the Group recognizes the incremental costs of obtaining a contracts as an expense when incurred if the amortization period of the asset is one year or less.

3. Critical Accounting Estimates and Assumptions

The Group makes estimates and assumptions concerning the future. The estimates and assumptions are continuously evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the current circumstances. Actual results may differ from these estimates.

Significant accounting estimates and assumptions applied in the preparation of these condensed consolidated interim financial statements are the same as those applied to the consolidated financial statements for the year ended December 31, 2017, except for the estimates used to determine income tax expense, and accounting estimates and assumptions for implementation of Korean IFRS 1109 and Korean IFRS 1115 explained as below.

(a) Impairment of financial assets

The provision for impairment for financial assets are based on assumptions about risk of default and expected loss rates. The Group uses judgement in making these assumptions and selecting the inputs to the impairment calculation based on the Group’s past history, existing market conditions as well as forward looking estimates at the end of each reporting period.

(b) Amortization of Contract Assets, Contract Liabilities and Contract Cost Assets

Contract assets, contract liabilities and contract cost assets recognized under the application of Korean IFRS 1115 are amortized over the expected periods of customer relationships. The estimate of the expected terms of customer relationship is based on the historical data. If management’s estimate changes, it may cause significant differences in the timing of revenue recognition and amounts recognized.

¹ The Group did not conduct fair value estimation since the book amount is a reasonable approximation of the fair value.

² In the prior financial year, a portion of the equity instrument was classified asavailable-for-sale financial assets and financial assetsheld-to-maturity.

³  As at December 31, 2017, equity instruments that do not have a quoted price in an active market are measured at cost because their fair value cannot be measured reliably and excluded from the fair value disclosures.

(2) Fair Value Hierarchy

Assets measured at fair value or for which the fair value is disclosed are categorized within the fair value hierarchy, and the defined levels are as follows:

• Quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1).

• Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (that is, prices) or indirectly (that is, derived from prices) (Level 2).

• Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs) (Level 3).

(6) Gain and Loss on Valuation at the Transaction Date

In the case that the Group values derivative financial instruments using inputs not based on observable market data, and the fair value calculated by the said valuation technique differs from the transaction price, then the fair value of the financial instruments is recognized as the transaction price. The difference between the fair value at initial recognition and the transaction price is deferred and amortized using a straight-line method by maturity of the financial instruments. However, in the case that inputs of the valuation techniques become observable in markets, the remaining deferred difference is immediately recognized in full in profit of the reporting period.

The amount of difference deferred and its changes for thesix-month periods ended June 30, 2018 and 2017, are as follows:

(in millions of Korean won)	2018			2017

Report on Review of Interim Financial Statements

(English Translation of a Report Originally Issued in Korean)

To the Shareholders and Board of Directors of

KT Corporation

Reviewed Financial Statements

We have reviewed the accompanying separate interim financial statements of KT Corporation (the “Company”). These financial statements consist of the separate interim statement of financial position as at June 30, 2018, and the related separate interim statements of profit or loss, separate interim statements of comprehensive income for the three-month andsix-month periods ended June 30, 2018 and 2017, and separate interim statements of changes in equity and separate interim statements of cash flows for thesix-month periods ended June 30, 2018 and 2017, and a summary of significant accounting policies and other explanatory notes, expressed in Korean won.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these separate interim financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“Korean IFRS”) 1034Interim Financial Reporting, and for such internal control as management determines is necessary to enable the preparation of separate interim financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to issue a report on these separate interim financial statements based on our review.

We conducted our review in accordance with quarterly or semi-annual review standards established by the Securities and Futures Commission of the Republic of Korea. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Korean Standard on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe the accompanying separate interim financial statements are not presented fairly, in all material respects, in accordance with the Korean IFRS 1034Interim Financial Reporting.

Samil PricewaterhouseCoopers, 100, Hangangdaero,Yongsan-gu, Seoul 04386, Korea,www.samil.com

Other Matters

We have audited the separate statement of financial position of the Company as at December 31, 2017, and the related separate statements of profit or loss, comprehensive income, changes in equity and cash flows for the year then ended, in accordance with Korean Standards on Auditing. We expressed an unqualified opinion on those financial statements, not presented herein, in our audit report dated March 2, 2018. The separate statement of financial position as at December 31, 2017, presented herein for comparative purposes, is consistent, in all material respects, with the above audited statement of financial position as at December 31, 2017.

Review standards and their application in practice vary among countries. The procedures and practices used in the Republic of Korea to review such financial statements may differ from those generally accepted and applied in other countries.

August 14, 2018

This report is effective as of August 14, 2018, the review report date. Certain subsequent events or circumstances, which may occur between the review report date and the time of reading this report, could have a material impact on the accompanying separate interim financial statements and notes thereto. Accordingly, the readers of the review report should understand that there is a possibility that the above review report may have to be revised to reflect the impact of such subsequent events or circumstances, if any.

Notes to the Separate Interim Financial Statements

June 30, 2018 and 2017 (Unaudited), and December 31, 2017

1. General Information

KT Corporation (the “Company”) commenced operations on January 1, 1982, when it was spun off from the Korea Communications Commission (formerly, the Korean Ministry of Information and Communications) to provide telephone services and to engage in the development of advanced communications services under the Act of Telecommunications of Korea. The address of the Company’s registered office is 90,Buljeong-ro,Bundang-gu, Seongnam City, Gyeonggi Province, Korea.

On October 1, 1997, upon the announcement of the Act on the Management of Government-Invested Institutions and the Privatization Law, the Company became a government-funded institution under the Commercial Code of Korea.

On December 23, 1998, the Company’s shares were listed on the Korea Exchange.

On May 29, 1999, the Company issued 24,282,195 additional shares and issued American Depository Shares (ADS), representing new shares and 20,813,311 government-owned shares, at the New York Stock Exchange. On July 2, 2001, the additional ADS representing 55,502,161 government-shares were issued at the New York Stock Exchange.

In 2002, the Company acquired the entire government-owned shares in accordance with the Korean Government’s privatization plan. At the end of the reporting period, the Korean Government does not own any share in the Company.

2. Significant Accounting Policies

2.1 Basis of Preparation

The Company maintains its accounting records in Korean won and prepares statutory financial statements in the Korean language (Hangul) in accordance with the International Financial Reporting Standards as issued by the Republic of Korea (Korean IFRS). The accompanying separate interim financial statements have been condensed, restructured and translated into English from the Korean language financial statements.

Certain information attached to the Korean language financial statements, but not required for a fair presentation of the Company’s financial position, financial performance or cash flows, is not presented in the accompanying separate interim financial statements.

The separate interim financial statements of the Company as at and for thesix-month period ended June 30, 2018, have been prepared in accordance with Korean IFRS 1034Interim Financial Reporting. These separate interim financial statements have been prepared in accordance with Korean IFRS which is effective or has been early adopted as at June 30, 2018.

Notes to the Separate Interim Financial Statements

June 30, 2018 and 2017 (Unaudited), and December 31, 2017

(1) New standards and amendments adopted by the Company

The Company newly applied the following amended and enacted standards and interpretations for the annual period beginning on January 1, 2018, and the application has following impacts on the separate interim financial statements.

• Amendments to Korean IFRS 1028Investments in Associates and Joint Ventures

When an investment in an associate or a joint venture is held by, or is held indirectly through, an entity that is a venture capital organization, or a mutual fund, unit trust and similar entities including investment-linked insurance funds, the entity may elect to measure that investment at fair value through profit or loss in accordance with Korean IFRS 1109. The amendments clarify that an entity shall make this election separately for each associate of joint venture, at initial recognition of the associate or joint venture. The Company does not expect the amendments to have a significant impact on the financial statements because the Company is not a venture capital organization.

• Amendment to Korean IFRS 1040Transfers of Investment Property

Paragraph 57 of Korean IFRS 1040 clarifies that a transfer to, or from, investment property, including property under construction, can only be made if there has been a change in use that is supported by evidence, and provides a list of circumstances as examples. The Company does not expect the amendment to have a significant impact on the financial statements.

• Amendments to Korean IFRS 1102Share-based Payment

Amendments to Korean IFRS 1102 clarify accounting for a modification to the terms and conditions of a share-based payment that changes the classification of the transaction from cash-settled to equity-settled. Amendments also clarify that the measurement approach should treat the terms and conditions of a cash-settled award in the same way as for an equity-settled award. The Company does not expect the amendments to have a significant impact on the financial statements.

• Enactment of Interpretation 2122Foreign Currency Transaction and Advance Consideration

According to the enactment, the date of the transaction for the purpose of determining the exchange rate to use on initial recognition of the related asset, expense or income (or part of it) is the date on which an entity initially recognizes thenon-monetary asset ornon-monetary liability arising from the payment or receipt of advance consideration. The Company does not expect the enactment to have a significant impact on the financial statements.

• Korean IFRS 1109Financial Instruments

The Company has applied Korean IFRS 1109Financial Instruments on January 1, 2018, the date of initial application. In accordance with the transitional provisions in Korean IFRS 1109, comparative figures have not been restated. See Note 28 for further details on the impact of the application of the standard.

KT Corporation

Notes to the Separate Interim Financial Statements

June 30, 2018 and 2017 (Unaudited), and December 31, 2017

• Korean IFRS 1115Revenue from Contracts with Customers

The Company has elected to apply Korean IFRS 1115Revenue from Contracts with Customers. In accordance with the transition provisions in Korean IFRS 1115, comparative figures have not been restated. The Company elected the modified retrospective approach and recognized the cumulative impact of initially applying the revenue standard as an adjustment to retained earnings as at January 1 2018, the period of initial application. See Note 28 for further details on the impact of the application of the standard.

(2) New standards and interpretations not yet adopted by the Company

Certain new accounting standards and interpretations that have been published that are not mandatory for annual reporting period commencing January 1, 2018 and have not been early adopted by the Company are set out below.

• Enactment of Korean IFRS 1116Leases

Korean IFRS 1116Leases issued on May 22, 2017 is effective for annual periods beginning on or after January 1, 2019, with early adoption permitted. This standard will replace Korean IFRS 1017Leases. The Company will apply the standards for annual periods beginning on or after January 1, 2019.

Under the new standard, with implementation of a single lease model, lessee is required to recognize assets and liabilities for all lease which lease term is 12 months or more and underlying assets are not low value assets. A lessee is required to recognize aright-of-use asset and a lease liability representing its obligation to make lease payments.

The Company performed an impact assessment to identify potential financial effects of applying Korean IFRS 1116. The Company is analyzing the effects on the financial statements based on available information as at June 30, 2018 to identify effects on 2018 interim financial statements; however, it is difficult to provide reasonable estimates of financial effects until the analysis is complete.

2.2 Accounting Policies

Significant accounting policies and method of computation used in the presentation of the condensed separate interim financial statements are consistent with those of the separate financial statements for the year ended December 31, 2017, except for the changes due to the application of amendment and enactments of standards described in Note 2.1 the one described below.

2.2.1 Income Tax Expense

Income tax expense for the interim period is recognized based on management’s best estimate of the weighted average annual income tax rate expected for the full financial year. The estimated average annual tax rate is applied to thepre-tax income.

KT Corporation

Notes to the Separate Interim Financial Statements

June 30, 2018 and 2017 (Unaudited), and December 31, 2017

2.2.2 Financial Assets

(a) Classification

From January 1, 2018, the Company classifies its financial assets in the following measurement categories:

• those to be measured subsequently at fair value (either through other comprehensive income, or through profit or loss), and

• those to be measured at amortized cost

The classification depends on the entity’s business model for managing the financial assets and the contractual terms of the cash flows.

For financial assets measured at fair value, gains and losses will either be recorded in profit or loss or other comprehensive income. For investments in debt instruments, this will depend on the business model in which the investment is held. The Company reclassifies debt investments when and only when its business model for managing those assets changes.

For investments in equity instruments that are not held for trading, this will depend on whether the Company has made an irrevocable election at the time of initial recognition to account for the equity investment at fair value through other comprehensive income. Changes in fair value of the investments in equity instruments that are not accounted for as other comprehensive income are recognized in profit or loss.

(b) Measurement

At initial recognition, the Company measures a financial asset, in the case of a financial asset not at fair value through profit or loss, at its fair value plus transaction costs that are directly attributable to the acquisition of the financial asset or the issuance of the financial liabilities. Transaction costs of financial assets carried at fair value through profit or loss are expensed in profit or loss.

Hybrid (combined) contracts with embedded derivatives are considered in their entirety when determining whether their cash flows are solely payment of principal and interest.

Debt instruments

Subsequent measurement of debt instruments depends on the Company’s business model for managing the asset and the cash flow characteristics of the asset. The Company classifies its debt instruments into one of the following three measurement categories:

• Amortized cost: Assets that are held for collection of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortized cost. A gain or loss on a debt investment that is subsequently measured at amortized cost and is not part of a hedging relationship is recognized in profit or loss when the asset is derecognized or impaired. Interest income from these financial assets is included in ‘finance income’ using the effective interest rate method.

12

KT Corporation

Notes to the Separate Interim Financial Statements

June 30, 2018 and 2017 (Unaudited), and December 31, 2017

• Fair value through other comprehensive income: Assets that are held for collection of contractual cash flows and for selling the financial assets, where the assets’ cash flows represent solely payments of principal and interest, are measured at fair value through other comprehensive income. Movements in the carrying amount are taken through other comprehensive income, except for the recognition of impairment loss (and reversal of impairment loss), interest income and foreign exchange gains and losses which are recognized in profit or loss. When the financial asset is derecognized, the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to profit or loss. Interest income from these financial assets is included in ‘finance income’ using the effective interest rate method. Foreign exchange gains and losses are presented in ‘finance income or finance costs’ and impairment loss in ‘finance costs’.

• Fair value through profit or loss: Assets that do not meet the criteria for amortized cost or fair value through other comprehensive income are measured at fair value through profit or loss. A gain or loss on a debt investment that is subsequently measured at fair value through profit or loss and is not part of a hedging relationship is recognized in profit or loss and presented net in the statement of profit or loss within ‘finance income or finance costs ’ in the period in which it arises.

Equity instruments

The Company subsequently measures all equity investments at fair value. Where the Company’s management has elected to present fair value gains and losses on equity investments in other comprehensive income, there is no subsequent reclassification of fair value gains and losses to profit or loss following the derecognition of the investment. Dividends from such investments continue to be recognized in profit or loss as ‘finance income’ when the Company’s right to receive payments is established.

Changes in the fair value of financial assets at fair value through profit or loss are recognized in ‘finance income or finance costs’ in the statement of profit or loss as applicable. Impairment loss (and reversal of impairment loss) on equity investments measured at fair value through other comprehensive income are not reported separately from other changes in fair value.

(c) Impairment

The Company assesses on a forward looking basis the expected credit losses associated with its debt instruments carried at amortized cost and fair value through other comprehensive income. The impairment methodology applied depends on whether there has been a significant increase in credit risk. For trade receivables, the Company applies the simplified approach, which requires expected lifetime losses to be recognized from initial recognition of the receivables.

Notes to the Separate Interim Financial Statements

June 30, 2018 and 2017 (Unaudited), and December 31, 2017

(d) Derivative instruments and Hedging Activities

Derivatives are initially recognized at fair value on the date a derivative contract is entered into and are subsequently remeasured at their fair value at the end of each reporting period. Changes in the fair value of any derivative instrument that does not qualify for hedge accounting are recognized immediately in profit or loss. The accounting for subsequent changes in fair value depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged and the type of hedge relationship designated.

The Company designates their currency derivatives as hedges of foreign exchange risk associated with the cash flows of highly probable forecast transactions.

The Company documents at the inception of the hedging transaction the economic relationship between hedging instruments and hedged items including whether the hedging instrument is expected to offset changes in cash flows of hedged items. The Company documents its risk management objective and strategy for undertaking various hedge transactions at the inception of each hedge relationship.

The fair values of various derivative financial instruments used for hedging purposes are disclosed in Note 27.

The full fair value of a hedging derivative is classified as anon-current asset or liability when the remaining maturity of the hedged item is more than 12 months; it is classified as a current asset or liability when the remaining maturity of the hedged item is less than 12 months. Derivatives held for trading are classified as a current asset or liability.

The new accounting policies related to hedge accounting applied from January 1, 2018 are as follows:

• Cash flow hedges

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in the cash flow hedge reserve within equity, limited to the cumulative change in fair value (present value) of the hedged item (the present value of the cumulative change in the future expected cash flows of the hedged item) from the inception of the hedge. The ineffective portion is recognized in ‘finance income (finance costs)’.

Amounts accumulated in equity are reclassified in the periods when the hedged item affects profit or loss.

When a hedging instrument expires, or is sold, terminated, exercised, or when a hedge no longer meets the criteria for hedge accounting, any accumulated cash flow hedging reserve cumulative deferred gain or loss and deferred costs of hedging in equity at that time remains in equity until the forecast transaction occurs, resulting in the recognition of anon-financial asset such as inventory. When the forecast transaction is no longer expected to occur, the cumulative gain or loss and deferred costs of hedging that were reported in equity are immediately reclassified to profit or loss.

2.2.3 Revenue Recognition

From January 1, 2018, the Company has applied Korean IFRS 1115Revenue from Contracts with Customers.

(a) Identifying performance obligations

The Company provides telecommunication services and sells handsets as their main business. With the implementation of Korean IFRS 1115, the Company identifies performance obligations with a customer such as providing telecommunication services, selling handsets and others. The timing of revenue recognition depends on whether a performance obligation is satisfied at a point in time or over time. Where a performance obligation is satisfied over time, the related revenue is also recognized over time.

(b) Allocation the transaction price

With the implementation of Korean IFRS 1115, the Company allocates the transaction price to each performance obligation identified in the contract based on a relative stand-alone selling prices of the goods or services being provided to the customer. To allocate the transaction price to each performance obligation on a relative stand-alone price basis, the Company determines the stand-alone selling price at contract inception of the distinct goods or services underlying each performance obligation in the contract and allocate the transaction price in proportion to those stand-alone selling price. The stand-alone selling price is the price at which the Company would sell promised goods or services separately to the customer. The best evidence of a stand-alone selling price is the observable price of a goods or services when the Company sells that goods or services separately in similar circumstances and to similar customers. The Company recognizes the allocated amount as contract assets or contract liabilities, and amortizes it through the remaining period which is adjusted in operating income.

(c) Incremental costs of obtaining a contract

The Company pays the commission fees when new customer subscribe for telecommunication services. The incremental costs of obtaining a contract are those commission fees that the Company incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained.

According to Korean IFRS 1115, the Company recognizes as an asset the incremental cost of obtaining contract and amortize it through the contract period. However, as a practical expedient, the Company recognizes the incremental costs of obtaining a contracts as an expense when incurred if the amortization period of the asset is one year or less.

(6) Gains and losses on valuation at the transaction date

In the case that the Company measured the fair value of derivative financial instruments with unobservable inputs, the Company recognized the fair value of the instrument at the transaction price if the fair value at initial measurement is different from the transaction price. The difference between the fair value at initial measurement and the transaction price is deferred and amortized using a straight-line method until the maturity of the instrument. However, in the case where inputs of the valuation techniques become observable in markets, the remaining deferred difference is immediately recognized in full in profit of the reporting period.

In relation to this, details and changes of the total deferred difference for thesix-month periods ended June 30, 2018 and 2017, are as follows:
