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, 2019, and the related consolidated interim statements of profit or loss and comprehensive income for the three-month andsix-month periods ended June 30, 2019 and 2018, and consolidated interim statements of changes in equity and cash flows for thesix-month periods ended June 30, 2019 and 2018, 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, 2018, 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 11, 2019. The consolidated statement of financial position as at December 31, 2018, presented herein for comparative purposes, is consistent, in all material respects, with the above audited statement of financial position as at December 31, 2018.

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.

This report is effective as of August 14, 2019, 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.

2. Significant Accounting Policies

2.1 Basis of Preparation

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

The Group’s consolidated interim financial statements for the six-month period ended June 30, 2019, have been prepared in accordance with Korean IFRS 1034Interim Financial Reporting. These consolidated interim financial statements have been prepared in accordance with Korean IFRS which is effective or early adopted as at June 30, 2019.

(1) New and amended standards adopted by the Group

The Group has applied the following standards and amendments for the first time for their annual reporting period commencing January 1, 2019.

• Enactment of Korean IFRS 1116Leases

Korean IFRS 1116Leases replaces Korean IFRS 1017Leases. Under Korean IFRS 1116, with implementation of a single lease model, lessee is required to recognize assets and liabilities for all lease which lease term is over 12 months 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.

With implementation of Korean IFRS 1116Lease, the Group has changed accounting policy. The Group has adopted Korean IFRS 1116 retrospectively, as permitted under the specific transitional provisions in the standard, and recognized the cumulative impact of initially applying the standard as at January 1, 2019, the date of initial application. The Group has not restated comparatives for the 2018 reporting period. The impact of the adoption of the leasing standard and the new accounting policies are disclosed in Note 30.

• Korean IFRS 1109Financial Instruments

The narrow-scope amendments made to Korean IFRS 1109Financial Instruments enable entities to measure certain prepayable financial assets with negative compensation at amortized cost. When a modification of a financial liability measured at amortized cost that does not result in the derecognition, a modification gain or loss shall be recognized in profit or loss. The amendment does not have a significant impact on the financial statements.

• Amendments to Korean IFRS 1019Employee Benefits

The amendments require that an entity shall calculate current service cost and net interest for the remainder of the reporting period after a plan amendment, curtailment or settlement based on updated actuarial assumptions from the date of the change. The amendments also require that a reduction in a surplus must be recognized in profit or loss even if that surplus was not previously recognized because of the impact of the asset ceiling. The amendment does not have a significant impact on the financial statements.

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

The amendments clarify that an entity shall apply Korean IFRS 1109 to financial instruments in an associate or joint venture to which the equity method is not applied. These include long-term interests that, in substance, form part of the entity’s net investment in an associate or joint venture. The amendment does not have a significant impact on the financial statements

• Enactment to Interpretation of Korean IFRS 2123Uncertainty over Income Tax Treatments

The Interpretation explains how to recognize and measure deferred and current income tax assets and liabilities where there is uncertainty over a tax treatment, and includes guidance on how to determine whether each uncertain tax treatment is considered separately or together. It also presents examples of circumstances where a judgement or estimate is required to be reassessed. The enactment does not have a significant impact on the financial statements.

• Annual Improvements to Korean IFRS 2015 – 2017 Cycle:

• Korean IFRS 1103Business Combination

The amendments clarify that when a party to a joint arrangement obtains control of a business that is a joint operation, and had rights to the assets and obligations for the liabilities relating to that joint operation immediately before the acquisition date, the transaction is a business combination achieved in stages. In such cases, the acquirer shall remeasure its entire previously held interest in the joint operation. The amendment does not have a significant impact on the financial statements.

• Korean IFRS 1111Joint Agreements

The amendments clarify that when a party that participates in, but does not have joint control of, a joint operation might obtain joint control of the joint operation in which the activity of the joint operation constitutes a business.

(5) Valuation Processes for Fair Value Measurements Categorized Within Level 3

The Group uses external experts that perform the fair value measurements required for financial reporting purposes. External experts report directly to the chief financial officer (CFO), and discusses valuation processes and results with the CFO in line with the Group’s closing dates.

(6) Gains and Losses 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 instrument. 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 for the year.

In relation to this, details and changes of the total deferred difference for the six-month periods ended June 30, 2019 and 2018, are as follows:

(in millions of Korean won)	2019			2018

30. Changes in Accounting Policies

As explained in Note 2.1 (1), the Group has adopted Korean IFRS 1116, retrospectively, from January 1, 2019, but has not restated comparatives for the 2018 reporting period, as permitted under the specific transitional provisions in the standard. The reclassifications and the adjustments arising from the new leasing rules are, therefore, recognized in the consolidated statement of financial position on January 1, 2019.

(1) Adjustments recognized on adoption of Korean IFRS 1116 Lease

On adoption of Korean IFRS 1116, the Group recognized lease liabilities in relation to leases which had previously been classified as ‘operating leases’ under the principles of Korean IFRS 1017. These liabilities were measured at the present value of the remaining lease payments, discounted using the lessee’s incremental borrowing rate as at January 1, 2019. The weighted average lessee’s incremental borrowing rate applied to the lease liabilities on January 1, 2019 was 2.00%~7.48%.

For leases previously classified as ‘finance leases’, the Group recognized the carrying amount of the lease asset and lease liability immediately before transition as the carrying amount of theright-of-use asset and the lease liability at the date of initial application. The measurement principles of Korean IFRS 1116 are only applied after that date.

(in millions of Korean won)	2019
Operating lease commitments as at December 31, 20181	W	637,927
Discounted using the lessee’s incremental borrowing rate of at the date of initial application		615,786
Add: finance lease liabilities recognized as at December 31, 2018		163,858
Lease liability recognized as at January 1, 2019	W	779,644
Of which are:
Current lease liabilities	W	314,680
Non-current lease liabilities		464,964
	W	779,644

¹  It excluded short-term leases and leases for which the underlying asset is of low value.

The associatedright-of-use assets for property leases were measured on a retrospective basis as if the new rules had always been applied. Otherright-of use assets were measured at the amount equal to the lease liability, adjusted by the amount of any prepaid or accrued lease payments relating to that lease recognized in the consolidated statement of financial position as at December 31, 2018.

(ii) Amounts recognized in the consolidated statements of profit or loss

The consolidated statement of profit or loss shows the following amounts relating to leases:

	Six-Month Periods Ended June 30,

Expense relating to short-term leases		2,244		—
Expense relating to leases oflow-value assets that are not short-term leases		17,082		—
Expense relating to variable lease payments not included in lease liabilities		3,127		—

The total cash outflow for leases forsix-month period ended June 30, 2019, wasW274,008 million.

Notes to the Consolidated Interim Financial Statements

June 30, 2019 and 2018 (Unaudited), and December 31, 2018

The change in accounting policy affected the following items in the consolidated statement of financial position on January 1, 2019:

• property and equipment: decrease byW209,760 million

• intangible assets: decrease byW26,207 million

• right-of-use assets: increase byW925,570 million

• lease receivables: increase byW3,376 million

• prepayments: decrease byW2 million

• prepaid expenses: decrease byW83,074 million

• other liabilities: increase byW266 million

• lease liabilities: increase byW615,786 million

The net impact on retained earnings on January 1, 2019, was a decrease ofW6,149 million

(iii) Practical expedient applied

In applying Korean IFRS 1116 for the first time, the Group did not used the practical expedients permitted by the standard:

• the use of a single discount rate to a portfolio of leases with reasonably similar characteristics

• reliance on previous assessments on whether leases are onerous

• the accounting for operating leases with a remaining lease term of less than 12 months as at January 1, 2019, as short-term leases

• the exclusion of initial direct costs for the measurement of theright-of-use asset at the date of initial application, and

• the use of hindsight in determining the lease term where the contract contains options to extend or terminate the lease

The Group has also elected not to reassess whether a contract is, or contains a lease at the date of initial application. Instead, for contracts entered into before the transition date, the Group relied on its assessment made applying Korean IFRS 1017 and Interpretation 2104Determining whether an Arrangement contains a Lease.

(2) The Group’s leasing activities and how these are accounted for

The Group leases various repeater server rack, offices, track facilities, machinery, and cars. Rental contracts are typically made for fixed periods of 1 to 10 years, but may have extension options as described in (ii) below. Lease terms are negotiated on an individual basis and contain a wide range of different terms and conditions. The lease agreements do not impose any covenants, but leased assets may not be used as security for borrowing purposes

Notes to the Consolidated Interim Financial Statements

June 30, 2019 and 2018 (Unaudited), and December 31, 2018

Until the 2018 financial year, leases of property, plant and equipment were classified as either finance or operating leases. Payments made under operating leases (net of any incentives received from the lessor) were charged to profit or loss on a straight-line basis over the period of the lease.

From January 1, 2019, leases are recognized as aright-of-use asset and a corresponding liability at the date at which the leased asset is available for use by the Group. Each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. Theright-of-use asset is depreciated over the shorter of the asset’s useful life and the lease term on a straight-line basis.

Assets and liabilities arising from a lease are initially measured on a present value basis. Lease liabilities include the net present value of the following lease payments.

• fixed payments (includingin-substance fixed payments), less any lease incentives receivable

• variable lease payment that are based on an index or a rate

• amounts expected to be payable by the lessee under residual value guarantees

• the exercise price of a purchase option if the lessee is reasonably certain to exercise that option, and

• payments of penalties for terminating the lease, if the lease term reflects the lessee exercising that option

The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be determined, the lessee’s incremental borrowing rate is used, being the rate that the lessee would have to pay to borrow the funds necessary to obtain an asset of similar value in a similar economic environment with similar terms and conditions.

Right-of-use assets are measured at cost comprising the following:

• the amount of the initial measurement of lease liability

• any lease payments made at or before the commencement date less any lease incentives received

• any initial direct costs (leasehold deposits), and

• restoration costs

• Present value discount on leasehold deposits

Payments associated with short-term leases and leases oflow-value assets are recognized on a straight-line basis as an expense in profit or loss. Short-term leases are leases with a lease term of 12 months or less.Low-value assets comprise tools and equipment.

Notes to the Consolidated Interim Financial Statements

June 30, 2019 and 2018 (Unaudited), and December 31, 2018

(i) Variable lease payments

There are no contracts with variable lease payments included in lease liabilities.

(ii) Extension and termination options.

Extension options are included in a number of property across the Group. These terms are used to maximize operational flexibility in terms of managing contracts. The majority of extension options held are exercisable only by the Group and not by the respective lessor. There are no contracts with termination options.

(iii) Residual value guarantees

The Group does not provide residual value guarantees in relation to equipment leases to optimize lease costs during the contract period.

31. Events after the Reporting Period

After the reporting period, the Group issued overseas bonds as follows:

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 of the Company as at June 30, 2019, and the related separate interim statements of profit or loss and comprehensive income for the three-month andsix-month periods ended June 30, 2019 and 2018, and separate interim statements of changes in equity and cash flows for thesix-month periods ended June 30, 2019 and 2018, 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 Standards 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 Korean IFRS 1034 Interim 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, 2018, 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 11, 2019. The separate statement of financial position as at December 31, 2018, presented herein for comparative purposes, is consistent, in all material respects, with the above audited statement of financial position as at December 31, 2018.

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.

The amendment does not have a significant impact on the financial statements.

• Amendments to Korean IFRS 1019Employee Benefits

The amendments require that an entity shall calculate current service cost and net interest for the remainder of the reporting period after a plan amendment, curtailment or settlement based on updated actuarial assumptions from the date of the change.

The amendment does not have a significant impact on the financial statements.

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

These include long-term interests that, in substance, form part of the entity’s net investment in an associate or joint venture. The amendment does not have a significant impact on the financial statements.

• Enactment to Interpretation of Korean IFRS 2123Uncertainty over Income Tax Treatments

The Interpretation explains how to recognize and measure deferred and current income tax assets and liabilities where there is uncertainty over a tax treatment, and includes guidance on how to determine whether each uncertain tax treatment is considered separately or together.

• Paragraph 57A of Korean IFRS 1012Income Tax

The amendment is applied to all the income tax consequences of dividends and requires an entity to recognize the income tax consequences of dividends in profit or loss, other comprehensive income or equity according to where the entity originally recognized those past transactions or events. The amendment does not have a significant impact on the financial statements.

• Korean IFRS 1023Borrowing Costs

(5) Valuation Processes for Fair Value Measurements Categorized Within Level 3

The Company uses external experts that perform the fair value measurements required for financial reporting purposes. External experts report directly to the chief financial officer (CFO), and discusses valuation processes and results with the CFO in line with the Company’s closing dates.

(6) Gains and Losses on Valuation at the Transaction Date

In the case that the Company 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 instrument. 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 for the period.

28. Changes in Accounting Policies

As explained in Note 2.1 (1), the Company has adopted Korean IFRS 1116, retrospectively, from January 1, 2019, but has not restated comparatives for the 2018 reporting period, as permitted under the specific transitional provisions in the standard. The reclassifications and the adjustments arising from the new leasing rules are, therefore, recognized in the statement of financial position on January 1, 2019.

(1) Adjustments recognized on adoption of Korean IFRS 1116 Lease

On adoption of Korean IFRS 1116, the Company recognized lease liabilities in relation to leases which had previously been classified as ‘operating leases’ under the principles of Korean IFRS 1017. These liabilities were measured at the present value of the remaining lease payments, discounted using the lessee’s incremental borrowing rate as at January 1, 2019. The weighted average lessee’s incremental borrowing rate applied to the lease liabilities on January 1, 2019 was 3.22%.

For leases previously classified as ‘finance leases’, the Company recognized the carrying amount of the lease asset and lease liability immediately before transition as the carrying amount of theright-of-use asset and the lease liability at the date of initial application. The measurement principles of Korean IFRS 1116 are only applied after that date.

(in millions of Korean won)	2019
Operating lease commitments as at December 31, 20181	W	587,931
Discounted using the lessee’s incremental borrowing rate of at the date of initial application		559,512
Add: finance lease liabilities recognized as at December 31, 2018		163,710
Add: adjustments as a result of a different treatment of extension and termination options		60,678
Lease liability recognized as at January 1, 2019	W	783,900
Of which are:
Current lease liabilities	W	313,471
Non-current lease liabilities		470,429
	W783,900

¹  It excluded short-term leases and leases for which the underlying asset is of low value.

KT Corporation

Notes to the Separate Interim Financial Statements

June 30, 2019 and 2018 (Unaudited), and December 31, 2018

The associatedright-of-use assets for property leases were measured on a retrospective basis as if the new rules had always been applied. Otherright-of use assets were measured at the amount equal to the lease liability, adjusted by the amount of any prepaid or accrued lease payments relating to that lease recognized in the statement of financial position as at December 31, 2018.

(i) Amounts recognized in the statement of financial position

The statement of financial position shows the following amounts relating to leases:

(in millions of Korean won)	June 30, 2019		January 1, 2019
Right-of-use assets
Property and building	W	561,326	W	610,986
Machinery and track facilities		207,335		234,507
Others		99,607		83,119

Non-current		431,918		470,429
	W	734,837	W	783,900

¹  It included in the line item ‘trade and other payables’ in the statement of financial position.

Additions to theright-of-use assets forsix-month period ended June 30, 2019 wereW163,113 million.

(ii) Amounts recognized in the statement of profit or loss

The statement of profit or loss shows the following amounts relating to leases:

	Six-Month Periods Ended June 30,
(in millions of Korean won)	2019		2018
Depreciation ofright-of-use assets
Property and building	W	161,322	W	—
Machinery and track facilities		46,341		—
Others		18,751		—
	W	226,414	W	—
Interest expense relating to lease liabilities	W	21,500	W	—
Expense relating to leases oflow-value assets that are not short-term leases		11,516		—

The total cash outflow for leases forsix-month period ended June 30, 2019, wasW217,520 million.

KT Corporation

Notes to the Separate Interim Financial Statements

June 30, 2019 and 2018 (Unaudited), and December 31, 2018

The change in accounting policy affected the following items in the statement of financial position on January 1, 2019:

• property and equipment: decrease byW209,703 million

• intangible assets: decrease byW26,208 million

• right-of-use assets: increase byW928,612 million

• lease receivables: increase byW3,376 million

• prepaid expenses: decrease byW82,036 million

• lease liabilities: increase byW620,190 million

The net impact on retained earnings on January 1, 2019, was a decrease ofW 6,149 million

(iii) Practical expedient applied

The Company has also elected not to reassess whether a contract is, or contains a lease at the date of initial application. Instead, for contracts entered into before the transition date, the Company relied on its assessment made applying Korean IFRS 1017 and Interpretation 2104Determining whether an Arrangement contains a Lease.

(2) The Company’s leasing activities and how these are accounted for

The Company leases various repeater server rack, offices, track facilities, machinery, and cars. Rental contracts are typically made for fixed periods of 1 to 10 years, but may have extension options as described in (ii) below. Lease terms are negotiated on an individual basis and contain a wide range of different terms and conditions. The lease agreements do not impose any covenants, but leased assets may not be used as security for borrowing purposes

Until the 2018 financial year, leases of property and equipment were classified as either finance or operating leases. Payments made under operating leases (net of any incentives received from the lessor) were charged to profit or loss on a straight-line basis over the period of the lease.

From January 1, 2019, leases are recognized as aright-of-use asset and a corresponding liability at the date at which the leased asset is available for use by the Company. Each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. Theright-of-use asset is depreciated over the shorter of the asset’s useful life and the lease term on a straight-line basis.

55

KT Corporation

Notes to the Separate Interim Financial Statements

June 30, 2019 and 2018 (Unaudited), and December 31, 2018

Assets and liabilities arising from a lease are initially measured on a present value basis. Lease liabilities include the net present value of the following lease payments.

• fixed payments (includingin-substance fixed payments), less any lease incentives receivable

• variable lease payment that are based on an index or a rate

• amounts expected to be payable by the lessee under residual value guarantees

• the exercise price of a purchase option if the lessee is reasonably certain to exercise that option, and

• payments of penalties for terminating the lease, if the lease term reflects the lessee exercising that option

The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be determined, the lessee’s incremental borrowing rate is used, being the rate that the lessee would have to pay to borrow the funds necessary to obtain an asset of similar value in a similar economic environment with similar terms and conditions.

Right-of-use assets are measured at cost comprising the following:

• the amount of the initial measurement of lease liability

• any lease payments made at or before the commencement date less any lease incentives received

• any initial direct costs (leasehold deposits), and

• restoration costs

• Present value discount on leasehold deposits

Payments associated with short-term leases and leases oflow-value assets are recognized on a straight-line basis as an expense in profit or loss. Short-term leases are leases with a lease term of 12 months or less.Low-value assets comprise tools and equipment.

(i) Variable lease payments

There are no contracts with variable lease payments

(ii) Extension and termination options

Extension options are included in a number of property and equipment across the Company. These terms are used to maximize operational flexibility in terms of managing contracts. The majority of extension options held are exercisable only by the Company and not by the respective lessor. There are no contracts with termination options.

(iii) Residual value guarantees

The Company does not provide residual value guarantees in relation to equipment leases to optimize lease costs during the contract period.
