Disclosure of basis of preparation [Abstract]
Basis of preparation	2. Basis of preparation (a) Statement of compliance The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”). IFRS are the standards and related interpretations issued by the International Accounting Standards Board (“IASB”). The consolidated financial statements were authorized for issue by the Board of Directors on February 7, 2018, which will be submitted for approval to the shareholders’ meeting on March 22, 2018. (b) Basis of measurement The consolidated financial statements have been prepared on the historical cost basis except for the following material items in the statement of financial position. • derivative financial instruments are measured at fair value • financial instruments at fair value through profit or loss are measured at fair value • available-for-sale • liabilities for cash-settled share-based payment arrangements are measured at fair value • financial liabilities designated as hedged items in a fair value hedge accounting of which changes in fair value attributable to the hedged risk are recognized in profit or loss • liabilities for defined benefit plans that are recognized at the net of the total present value of defined benefit obligations less the fair value of plan assets (c) Functional and presentation currency The financial statements of the parent and each subsidiary are prepared in functional currency of the respective operation. These consolidated financial statements are presented in Korean won, which is the Parent Company’s functional currency and the currency of the primary economic environment in which the Group operates. (d) Use of estimates and judgments The preparation of the consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are evaluated on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future years affected. In preparing the these consolidated financial statements, the significant judgments made by management in applying the Group’s accounting policies and the key sources of estimation uncertainty were the same as those that applied to the consolidated financial statements as of and for the year ended December 31, 2016, except for the changes below. During 2017, the credit card segment of the Group had accumulated sufficient experience to properly calculate probability of default, loss given default and credit conversion factors by considering the characteristics of borrowers, or its homogeneous borrowing groups, with credit evaluation system and risk evaluation system based on BASEL II; and based on this newly accumulated experience, the calculation methodology of loan losses has been changed from roll rate analysis model to internal model approach. As a result of changes in accounting estimates described above, allowances for loan losses and provision for unused credit lines decreased by W W (e) Changes in accounting policies The Group applied for the first time certain standards and amendments, which are effective for annual periods beginning on or after January 1, 2017. 1) Amendments to IAS 7, ‘Statement of Cash Flows’ The Group applied amendments to IAS 7, ‘ Statement of Cash Flows 2) Amendments to IAS 12, ‘Income Taxes’ The Group applied amendments to IAS 12, ‘ Income Taxes 3) Amendments to IFRS 12, ‘Disclosure of Interests in Other Entities’ The Group applied amendments to IFRS 12, ‘ Disclosure of Interests in Other Entities

Disclosure of significant accounting policies [Abstract]
Significant accounting policies	3. Significant accounting policies The significant accounting policies applied by the Group in preparation of its consolidated financial statements are included below. The accounting policies set out below have been applied consistently to all periods presented in these consolidated financial statements, except for the changes in accounting policies described in 2-(e). (a) Operating segments 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 CEO to make decisions about resources to be allocated to the segment and assess its performance, and for which discrete financial information is available. Segment results that are reported to the CEO include items directly attributable to a segment as well as those that can be allocated on a reasonable basis. The Group’s reportable segments consist of banking, credit card, securities, life insurance, and others. (b) Basis of consolidation i) Subsidiaries Subsidiaries are entities controlled by the Group. The Group controls an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. The financial statements of subsidiaries are included in the consolidated financial statements from the date on which control commences until the date on which control ceases. If a member of the Group uses accounting policies other than those adopted in the consolidated financial statements for the same transactions and events in similar circumstances, appropriate adjustments are made to its financial statements in preparing the consolidated financial statements. ii) Structured entity The Group establishes or invests in various structured entities. A structured entity is an entity designed so that its activities are not governed by way of voting rights. When assessing control of a structured entity, the Group considers factors such as the purpose and the design of the investee; its practical ability to direct the relevant activities of the investee; the nature of its relationship with the investee; and the size of its exposure to the variability of returns of the investee. The Group does not recognize any non-controlling iii) Intra-group transactions Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated in preparing the consolidated financial statements. Intra-group losses are recognized as expense if intra-group losses indicate an impairment that requires recognition in the consolidated financial statements. iv) Non-controlling Non-controlling non-controlling non-controlling (c) Business combinations i) Business combinations A business combination is accounted for by applying the acquisition method, unless it is a combination involving entities or businesses under common control. Each identifiable asset and liability is measured at its acquisition-date fair value except for below: • Leases and insurance contracts are required to be classified on the basis of the contractual terms and other factors • Only those contingent liabilities assumed in a business combination that are a present obligation and can be measured reliably are recognized • Deferred tax assets or liabilities are recognized and measured in accordance with IAS 12 Income Taxes • Employee benefit arrangements are recognized and measured in accordance with IAS 19 Employee Benefits • Indemnification assets are recognized and measured on the same basis as the indemnified liability or asset • Reacquired rights are measured on the basis of the remaining contractual terms of the related contract • Liabilities or equity instruments related to share-based payment transactions are measured in accordance with the method in IFRS 2 Share-based Payment • Assets held for sale are measured at fair value less costs to sell in accordance with IFRS 5 Non-current As of the acquisition date, non-controlling non-controlling The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the acquisition-date fair values of the assets transferred by the acquirer, the liabilities incurred by the acquirer to former owners of the acquiree and the equity interests issued by the acquirer. However, any portion of the acquirer’s share-based payment awards exchanged for awards held by the acquiree’s employees that are included in consideration transferred in the business combination shall be measured in accordance with the method described above rather than at fair value. Acquisition-related costs are costs the acquirer incurs to effect a business combination. Those costs include finder’s fees; advisory, legal, accounting, valuation and other professional or consulting fees; general administrative costs, including the costs of maintaining an internal acquisitions department; and costs of registering and issuing debt and equity securities. Acquisition-related costs, other than those associated with the issue of debt or equity securities, are expensed in the periods in which the costs are incurred and the services are received. The costs to issue debt or equity securities are recognized in accordance with IAS 32 Financial Instruments: Presentation Financial Instruments: Recognition and Measurement ii) Goodwill The Group measures goodwill at the acquisition date as: • the fair value of the consideration transferred; plus • the recognized amount of any non-controlling • if the business combination is achieved in stages, the fair value of the pre-existing • the net recognized amount (generally fair value) of the identifiable assets acquired and liabilities assumed. When the excess is negative, bargain purchase gain is recognized immediately in profit or loss. When the Group additionally acquires non-controlling (d) Investments in associates and joint ventures An associate is an entity in which the Group has significant influence, but not control, over the entity’s financial and operating policies. Significant influence is presumed to exist when the Group holds between 20 and 50 percent of the voting power of another entity. A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the arrangement. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control. The investment in an associate and a joint venture is initially recognized at cost, and the carrying amount is increased or decreased to recognize the Group’s share of the profit or loss and changes in equity of the associate and the joint venture after the date of acquisition. Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated in preparing the consolidated financial statements. Intra-group losses are recognized as expense if intra-group losses indicate an impairment that requires recognition in the consolidated financial statements. If an associate or a joint venture uses accounting policies different from those of the Group for like transactions and events in similar circumstances, appropriate adjustments are made to its financial statements in applying the equity method. When the Group’s share of losses exceeds its interest in an equity accounted investee, the carrying amount of that interest, including any long-term investments, is reduced to nil and the recognition of further losses is discontinued except to the extent that the Group has an obligation or has to make payments on behalf of the investee for further losses. (e) Cash and cash equivalents Cash and cash equivalents comprise cash balances and demand deposits with maturities of three months or less from the acquisition date that are subject to an insignificant risk of changes in their fair value, and are used by the Group in the management of its short-term commitments. (f) Non-derivative The Group recognizes and measures non-derivative held-to-maturity available-for-sale Upon initial recognition, non-derivative i) Financial assets at fair value through profit or loss A financial asset is classified as at fair value through profit or loss if it is held for trading or is designated at fair value through profit or loss. Upon initial recognition, transaction costs are recognized in profit or loss when incurred. Financial assets at fair value through profit or loss are measured at fair value, and changes therein are recognized in profit or loss. A financial asset other than a financial asset held for trading may be designated as at fair value through profit or loss (“FVTPL”) upon initial recognition if: • such designation eliminates or significantly reduces a recognition or measurement inconsistency that would otherwise arise; or • the financial asset forms part of a group of financial assets or financial liabilities or both, which is managed and its performance is evaluated on a fair value basis, in accordance with the Group’s documented risk management or investment strategy, and information about the grouping is provided internally on that basis; or • it forms part of a contract containing one or more embedded derivatives that would be required to be separated from the host contract. ii) Held-to-maturity A non-derivative held-to-maturity held-to-maturity iii) Loans and receivables Loans and receivables are financial assets with fixed or determinable payments that are not quoted in an active market. Subsequent to initial recognition, loans and receivables are measured at amortized cost using the effective interest method. iv) Available-for-sale Available-for-sale non-derivative available-for-sale held-to-maturity v) De-recognition The Group derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows on the financial asset in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred. Any interest in transferred financial assets that is created or retained by the Group is recognized as a separate asset or liability. If the Group retains substantially all the risks and rewards of ownership of the transferred financial assets, the Group continues to recognize the transferred financial assets and recognizes financial liabilities for the consideration received. vi) Offsetting between financial assets and financial liabilities Financial assets and financial liabilities are offset and the net amount is presented in the consolidated statement of financial position only when the Group currently has a legally enforceable right to offset the recognized amounts, and there is the intention to settle on a net basis or to realize the asset and settle the liability simultaneously. (g) Derivative financial instruments including hedge accounting Derivatives are initially recognized at fair value. Subsequent to initial recognition, derivatives are measured at fair value, and changes therein are accounted for as described below. i) Hedge accounting The Group holds forward exchange contracts, interest rate swaps, currency swaps and other derivative contracts to manage interest rate risk and foreign exchange risk. The Group designated derivatives as hedging instruments to hedge the risk of changes in the fair value of assets, liabilities or firm commitments (a fair value hedge) and foreign currency risk of highly probable forecasted transactions or firm commitments (a cash flow hedge). On initial designation of the hedge, the Group formally documents the relationship between the hedging instrument(s) and hedged item(s), including the risk management objectives and strategy in undertaking the hedge transaction, together with the methods that will be used to assess the effectiveness of the hedging relationship. • Fair value hedge • Cash flow hedge • Hedge of net investment The Effects of Changes in Foreign Exchange Rates ii) Separable embedded derivatives Embedded derivatives are separated from the host contract and accounted for separately only if the following criteria has been met: (a) the economic characteristics and risks of the embedded derivative are not closely related to those of the host contract; (b) a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and (c) the hybrid instrument is not measured at fair value with changes in fair value recognized in profit or loss. Changes in the fair value of separable embedded derivatives are recognized immediately in profit or loss. iii) Other derivative financial instruments Changes in the fair value of other derivative financial instrument not designated as a hedging instrument are recognized immediately in profit or loss. iv) Unobservable valuation differences at initial recognition Any difference between the fair value of over the counter derivatives at initial recognition and the amount that would be determined at that date using a valuation technique in a situation in which the valuation is dependent on unobservable parameters is not recognized in profit or loss but is recognized on a straight-line basis over the life of the instrument or immediately when the fair value becomes observable. (h) Impairment of financial assets A financial asset not carried at fair value through profit or loss is assessed at each reporting date to determine whether there is objective evidence that it is impaired. A financial asset is impaired if objective evidence indicates that a loss event has occurred after the initial recognition of the asset, and that the loss event had a negative effect on the estimated future cash flows of that asset that can be estimated reliably. However, losses expected as a result of future events, regardless of likelihood, are not recognized. In addition, for an investment in an equity security, a significant or prolonged decline in its fair value below its cost is objective evidence of impairment. If financial assets have objective evidence that they are impaired, impairment losses should be measured and recognized. Objective evidence that a financial asset or group of assets is impaired includes observable data that comes to the attention of the holder of the asset about the following loss events: • significant financial difficulty of the issuer or obligor • a breach of contract, such as a default or delinquency in interest or principal payments; • the lender, for economic or legal reasons relating to the borrower’s financial difficulty, granting to the borrower a concession that the lender would not otherwise consider • it becoming probable that the borrower will enter bankruptcy or other financial reorganization • the disappearance of an active market for that financial asset because of financial difficulties • observable data indicating that there is a measurable decrease in the estimated future cash flows from a group of financial assets since the initial recognition of those assets, although the decrease cannot yet be identified with the individual financial assets in the group. i) Loans and receivables The Group first assesses whether objective evidence of impairment exists individually for loans and receivables that are individually significant, and individually or collectively for financial assets that are not individually significant. If the Group determines that no objective evidence of impairment exists for an individually assessed financial asset, whether significant or not, it includes the asset in a group of financial assets with similar credit risk characteristics and collectively assesses them for impairment. Assets that are individually assessed for impairment and for which an impairment loss is or continues to be recognized are not included in a collective assessment of impairment. If there is objective evidence that an impairment loss on loans and receivables has been incurred, the amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset’s original effective interest rate (i.e., the effective interest rate computed at initial recognition). If the interest rate of a loan or receivable is a floating rate, the discount rate used to evaluate impairment loss is the current effective interest rate defined in the loan agreement. The present value of estimated future cash flows of secured financial assets is calculated by including cash flows from collateral after deducting costs to acquire and sell the collateral. In assessing collective impairment, the Group rates and classifies financial assets, based on credit risk assessment or credit rating assessment process that takes into account asset type, industry, regional location, collateral type, delinquency and other relative factors. Future cash flow of financial assets applicable to collective impairment assessment is estimated by using statistical modeling of historical trends of the probability of default, timing of recoveries and the amount of loss incurred, adjusted for management’s judgment as to whether current economic and credit conditions are such that the impairment losses are likely to be greater or less than suggested by historical modeling. In adjusting the future cash flow by historical modeling, the result has to be in line with changes and trends of observable data. Methodologies and assumptions used to estimate future cash flow are evaluated on a regular basis in order to reduce any discrepancy between impairment loss estimation and actual loss. Impairment losses are recognized in profit or loss and reflected in an allowance account against loans and receivables. When a subsequent event causes the amount of impairment loss to decrease, and the decrease can be related objectively to an event occurring after the impairment was recognized, the decrease in impairment loss is reversed through profit or loss of the year. ii) Available-for-sale When a decline in the fair value of an available-for-sale available-for-sale available-for-sale iii) Held-to-maturity An impairment loss in respect of held-to-maturity (i) Property and equipment Property and equipment are initially measured at cost and after initial recognition, are carried at cost less accumulated depreciation and accumulated impairment losses. The cost of property and equipment includes expenditures arising directly from the construction or acquisition of the asset, any costs directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management and the initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located. Items of property and equipment are measured at cost less accumulated depreciation and accumulated impairment losses. The cost of replacing a part of an item of property or 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, where the carrying amount of the replaced part is derecognized. The cost of the day to day servicing of property and equipment are recognized in profit or loss as incurred. Property and equipment are depreciated on a straight-line basis over the estimated useful lives, which most closely reflect the expected pattern of consumption of the future economic benefits embodied in the asset. Leased assets under finance lease are depreciated over the shorter of the lease term and their useful lives. The estimated useful lives for the current and comparative years are as follows: Descriptions Depreciation method Useful lives Buildings Straight-line 40 years Other properties Straight-line 4~5 years Depreciation methods, useful lives and residual value are reassessed at each fiscal year-end (j) Intangible assets Intangible assets are measured initially at cost and, subsequently, are carried at cost less accumulated amortization and accumulated impairment losses. Amortization of intangible assets except for goodwill is calculated on a straight-line basis over the estimated useful lives of intangible assets from the date that they are available for use. The residual value of intangible assets is zero. However, as there are no foreseeable limits to the periods over which club memberships are expected to be available for use, this intangible asset is determined as having indefinite useful lives and not amortized. Descriptions Useful lives Software, capitalized development cost 5 years Other intangible assets 5 years or contract periods Amortization periods and the amortization methods for intangible assets with finite useful lives are reviewed at the end of each reporting period. The useful lives of intangible assets that are not being amortized are reviewed at the end of each reporting period to determine whether events and circumstances continue to support indefinite useful life assessments for those assets. Changes are accounted for as changes in accounting estimates. i) Research and development Expenditures on research activities, undertaken with the prospect of gaining new technical knowledge and understanding, are recognized in profit or loss as incurred. Development expenditures are capitalized only if development costs can be measured reliably, the product or process is technically and commercially feasible, future economic benefits are probable, and the Group intends to and has sufficient resources to complete development and to use or sell the asset. Other development expenditures are recognized in profit or loss as incurred. ii) Subsequent expenditures Subsequent expenditures are capitalized only when they increase the future economic benefits embodied in the specific asset to which it relates. All other expenditures, including expenditures on internally generated goodwill and brands, are recognized in profit or loss as incurred. (k) Investment property Property held for the purpose of earning rentals or benefiting from capital appreciation is classified as investment property. Investment property is measured initially at its cost. Transaction costs are included in the initial measurement. Subsequently, investment property is carried at depreciated cost less any accumulated impairment losses. The estimated useful lives for the current and comparative years are as follows: Descriptions Depreciation method Useful lives Buildings Straight-line 40 years (l) Leased assets i) Classification of a lease The Group classifies and accounts for leases as either a finance or operating lease, depending on the terms. Leases where the lessee assumes substantially all of the risks and rewards of ownership are classified as finance leases. All other leases are classified as operating leases. ii) Lessee Under a finance lease, the lessee recognizes the leased asset and a liability for future lease payments. Upon initial recognition the leased asset is measured at an amount equal to the lower of its fair value and the present value of the minimum lease payments. Subsequent to initial recognition, the asset is accounted for in accordance with the accounting policy applicable to that asset. Under an operating lease, the lessee recognizes the lease payments as expense over the lease term and does not recognize the leased asset in its statement of financial position. iii) Lessor Under a finance lease, the lessor recognizes a finance lease receivable. Over the lease term the lessor accrues interest income on the net investment. The receipts under the lease are allocated between reducing the net investment and recognizing finance income, so as to produce a constant rate of return on the net investment. Under an operating lease, the lessor recognizes the lease payments as income over the lease term and the leased asset in its statement of financial position. (m) Assets held for sale Non-current non-current The Group recognizes an impairment loss for any initial or subsequent write-down of an asset (or disposal group) to fair value less costs to sell, and a gain for any subsequent increase in fair value less costs to sell, up to the cumulative impairment loss previously recognized in accordance with IAS 36 Impairment of Assets An asset that is classified as held for sale or part of a disposal group classified as held for sale is not depreciated (or amortized). (n) Impairment of non-financial The carrying amounts of the Group’s non-financial The Group estimates the recoverable amount of an individual asset. If it is impossible to measure the individual recoverable amount of an asset, then the Group estimates the recoverable amount of cash-generating unit (“CGU”). A CGU is the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. The recoverable amount of an asset or CGU is the greater of its value in use and its fair value less costs to sell. The value in use is estimated by applying a pre-tax An impairment loss is recognized if the carrying amount of an asset or a CGU exceeds its recoverable amount. Impairment losses are recognized in profit or loss. Goodwill acquired in a business combination is allocated to each CGU that is expected to benefit from the synergies arising from the goodwill acquired. Any impairment identified at the CGU level will first reduce the carrying value of goodwill and then be used to reduce the carrying amount of the other assets in the CGU on a pro rata basis. Except for impairment losses in respect of goodwill which are never reversed, an impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized. (o) Non-derivative The Group classifies non-derivative i) Financial liabilities at fair value through profit or loss Financial liabilities at fair value through profit or loss include financial liabilities held for trading or designated as such upon initial recognition. Subsequent to initial recognition, financial liabilities at fair value through profit or loss are measured at fair value, and changes therein are recognized in profit or loss. Upon initial recognition, transaction costs that are directly attributable to the acquisition are recognized in profit or loss as incurred. The criteria for designation of financial liabilities at FVTPL upon initial recognition are the same as those of financial assets at FVTPL. ii) Other financial liabilities Non-derivative The Group derecognizes a financial liability from the consolidated statement of financial position when it is extinguished (i.e. when the obligation specified in the contract is discharged, cancelled or expires). (p) Foreign currency i) Foreign currency transactions Transactions in foreign currencies are translated to the respective functional currencies of Group entities at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the reporting date are retranslated to the functional currency at the exchange rate at that date. The foreign currency gain or loss on monetary items is the difference between amortized cost in the functional currency at the beginning of the period, adjusted for effective interest and payments during the period, and the amortized cost in foreign currency translated at the exchange rate at the end of the reporting period. Non-monetary Foreign currency differences arising on translation are recognized in profit or loss, except for differences arising on the translation of available-for-sale Non-monetary ii) Foreign operations If the presentation currency of the Group is different from a foreign operation’s functional currency, the financial statements of the foreign operation are translated into the presentation currency using the following methods: The assets and liabilities of foreign operations, whose functional currency is not the currency of a hyperinflationary economy, are translated to presentation currency at exchange rates at the reporting date. The income and expenses of foreign operations are translated to functional currency at exchange rates at the dates of the transactions. Foreign currency differences are recognized in other comprehensive income. Any goodwill arising on the acquisition of a foreign operation and any fair value adjustments to the carrying amounts of assets and liabilities arising on the acquisition of that foreign operation is treated as assets and liabilities of the foreign operation. Thus they are expressed in the functional currency of the foreign operation and translated at the closing rate. When a foreign operation is disposed of, the relevant amount in the translation is transferred to profit or loss as part of the profit or loss on disposal. In any other partial disposal of a foreign operation, the relevant proportion is reclassified to profit or loss. Foreign exchange gains or losses arising from a monetary item receivable from or payable to a foreign operation, the settlement of which is neither planned nor likely to occur in the foreseeable future and which in substance is considered to form part of the net investment in the foreign operation, are recognized in other comprehensive income in the translation reserve. iii) Net investment in a foreign operation If the settlement of a monetary item receivable from or payable to a foreign operation is neither planned nor likely to occur in the foreseeable future, then foreign currency difference arising on the item which in substance is considered to form part of the net investment in the foreign operation, are recognized in the other comprehensive income and shall be reclassified to profit or loss on disposal of the investment. (q) Equity i) Capital stock Ordinary shares are classified as equity. Incremental costs directly attributable to the issuance of ordinary shares and share options are recognized as a deduction from equity, net of any tax effects. Preference share capital is classified as equity if it is non-redeemable, Preference share capital is classified as a liability if it is redeemable on a specific date or at the option of the shareholders, or if dividend payments are not discretionary. Dividends thereon are recognized as interest expense in profit or loss as accrued. ii) Hybrid bonds The Group classifies issued financial instruments, or their component parts, as a financial liability or an equity instrument depending on the substance of the contractual arrangement of such financial instruments. Hybrid bonds where the Group has an unconditional right to avoid delivering cash or another financial asset to settle a contractual obligation are classified as equity instruments and presented in equity. iii) Capital adjustments Changes in ownership interests in a subsidiary that do not result in a loss of control, such as the subsequent purchase or sale by a parent of a subsidiary’s equity instruments, are accounted for as equity transactions in capital adjustments. (r) Employee benefits i) Short-term employee benefits Short-term employee benefits are employee benefits that are due to be settled within 12 months after the end of the period in which the employees render the related service. When an employee has rendered service to the Group during an accounting period, the Group recognizes the undiscounted amount of short-term employee benefits expected to be paid in exchange for that service. ii) Other long-term employee benefits Other long-term employee benefits include employee benefits that are settled beyond 12 months after the end of the period in which the employees render the related service, and are calculated at the present value of the amount of future benefit that employees have earned in return for their service in the current and prior periods, less the fair value of any related assets. The present value is determined by discounting the expected future cash flows using the interes

Disclosure of financial risk management [Abstract]
Financial risk management	4. Financial risk management (a) Overview As a financial services provider, the Group is exposed to various risks relating to lending, credit card, insurance, securities investment, trading and leasing businesses, its deposit taking and borrowing activities in addition to the operating environment. The principal risks to which the Group is exposed are credit risk, market risk, interest rate risk, liquidity risk and operational risk. These risks are recognized, measured and reported in accordance with risk management guidelines established at the controlling company level and implemented at the subsidiary level through a carefully stratified checks-and-balances i) Risk management principles The Group risk management is guided by the following core principles: • identifying and managing all inherent risks; • standardizing risk management process and methodology; • ensuring supervision and control of risk management independent of business activities; • continuously assessing risk preference; • preventing risk concentration; • operating a precise and comprehensive risk management system including statistical models; and • balancing profitability and risk management through risk-adjusted profit management. ii) Risk management organization The Group risk management system is organized along the following hierarchy: from the top and at the controlling company level, the Group Risk Management Committee, the Group Risk Management Council, the Chief Risk Officer and the Group Risk Management Team, and at the subsidiary level, the Risk Management Committees and the Risk Management Team of the relevant subsidiary. The Group Risk Management Committee, which is under the supervision of the controlling company’s board of directors, sets the basic group wide risk management policies and strategies. The controlling company’s Chief Risk Officer reports to the Group Risk Management Committee, and the Group Risk Management Council, whose members consist of the controlling company’s Chief Risk Officer and the risk management team heads of each of subsidiaries, coordinates the risk management policies and strategies at the group level as well as at the subsidiary level among each of subsidiaries. Each of subsidiaries also has a separate Risk Management Committee, Risk Management Working Committee and Risk Management Team, whose tasks are to implement the group wide risk management policies and strategies at the subsidiary level as well as to set risk management policies and strategies specific to such subsidiary in line with the Group wide guidelines. The Group also has the Group Risk Management Team, which supports the controlling company’s Chief Risk Officer in his or her risk management and supervisory role. In order to maintain the group wide risk at an appropriate level, the Group use a hierarchical risk limit system under which the Group Risk Management Committee assigns reasonable risk limits for the entire group and each subsidiary, and the Risk Management Committee and the Management Council of each subsidiary manage the subsidiary-specific risks by establishing and managing risk limits in more detail by type of risk and type of product for each department and division within such subsidiary. The Group Risk Management Committee consists of directors of the controlling company. The Group Risk Management Committee convenes at least once every quarter and may also convene on an ad hoc basis as needed. Specifically, the Group Risk Management Committee does the following: (i) establish the overall risk management policies consistent with management strategies, (ii) set reasonable risk limits for the entire group and each of subsidiaries, (iii) approve appropriate investment limits or allowed loss limits, (iv) enact and amend risk management regulations, and (v) decide on other risk management-related issues the Board of Directors or the Group Risk Management Committee sees fit to discuss. The results of the Group Risk Management Committee meetings are reported to the Board of Directors of the controlling company. The Group Risk Management Committee makes decisions through affirmative votes by a majority of the committee members. The Group Risk Management Council is comprised of the controlling company’s chief risk officer, head of risk management team, and risk officers from each subsidiary. The Group Risk Management Council holds meetings for risk management executives from each subsidiary to discuss the Group’s group wide risk management guidelines and strategy in order to maintain consistency in the group wide risk policies and strategies. iii) Risk management framework The Group takes the following steps to implement the foregoing risk management principles: • Risk capital management – • Risk monitoring – • Risk review – • Risk management – (b) Credit risk i) Credit risk management Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet its contractual obligations, and arises principally from the Group’s receivables from customers and investment securities. The Group’s credit risk management encompasses all areas of credit that may result in potential economic loss, including not just transactions that are recorded on statements of financial position, but also off-balance • Credit Risk Management of Shinhan Bank Major policies for Shinhan Bank’s credit risk management, including Shinhan Bank’s overall credit risk management plan and credit policy guidelines, are determined by the Risk Policy Committee of Shinhan Bank, the executive decision-making body for management of credit risk. The Risk Policy Committee is headed by the Chief Risk Officer, and also comprises of the Chief Credit Officer, the heads of each business unit and the head of the Risk Management Department. In order to separate the loan approval functions from credit policy decision-making, Shinhan Bank has a Credit Review Committee that performs credit review evaluations, which focus on improving the asset quality and profitability from the loans being made, and operates separately from the Risk Policy Committee. Shinhan Bank complies with credit risk management procedures pursuant to internal guidelines and regulations and continually monitors and improves these guidelines and regulations. Its credit risk management procedures include: • credit evaluation and approval; • credit review and monitoring; and • credit risk assessment and control Each of Shinhan Bank’s borrowers is assigned a credit rating, which is based on a comprehensive internal credit evaluation system that considers a variety of criteria. For retail borrowers, the credit rating takes into account the borrower’s past dealings with Shinhan Bank and external credit rating information, among others. For corporate borrowers, the credit rating takes into account financial indicators as well as non-financial Loans are generally approved after evaluations and approvals by the manager at the branch level as well as the committee of the applicable business unit at Shinhan Bank. The approval limit for retail loans is made based on Shinhan Bank’s automated credit scoring system. In the case of large corporate loans, approval limits are also reviewed and approved by a Credit Officer at the headquarter level. Depending on the size and the importance of the loan, the approval process is further reviewed by the Credit Officer Committee or the Master Credit Officer Committee. If the loan is considered, further evaluation is made by the Credit Review Committee, which is Shinhan Bank’s highest decision-making body in relation to credit approval. Pursuant to the foregoing credit review and monitoring procedures and in order to promptly prevent deterioration of loan qualities, Shinhan Bank classifies potentially problematic borrowers into (i) borrowers that show early warning signals, (ii) borrowers that require close monitoring and (iii) normal borrowers, and treats them differentially accordingly. In order to maintain portfolio-level credit risk at an appropriate level, Shinhan Bank manages its loans using value-at-risk • Credit Risk Management of Shinhan Card Major policies for Shinhan Card’s credit risk management are determined by Shinhan Card’s Risk Management Council and Shinhan Card’s Risk Management Committee is responsible for approving them. Shinhan Card’s Risk Management Council is headed by the Chief Risk Officer, and also comprises of the heads of each business unit, supporting unit and relevant department at Shinhan Card. In order to separate credit policy decision-making from credit evaluation functions, Shinhan Card also has a Risk Management Committee, which evaluates applications for corporate loans exceeding a certain amount and other loans deemed important. Shinhan Card uses an automated credit scoring system to approve credit card applications or credit card authorizations. The credit scoring system is divided into two sub-systems: If a credit score awarded to an applicant is above a minimum threshold, the application is approved unless overridden based on other considerations such as delinquencies with other credit card companies. Shinhan Card continually monitors all accountholders and accounts using a behavior scoring system. The behavior scoring system predicts a cardholder’s payment pattern by evaluating the cardholder’s credit history, card usage and amounts, payment status and other relevant data. The behavior score is recalculated each month and is used to manage the accounts and approval of additional loans and other products to the cardholder. Shinhan Card also uses the scoring system to monitor its overall risk exposure and to modify its credit risk management strategy. ii) Maximum exposure to credit risk The Group’s maximum exposure to credit risk without taking account of any collateral held or other credit enhancements as of December 31, 2016 and 2017 are as follows: 2016 2017 Due from banks and loans (*1)(*3): Banks W 13,922,969 13,373,140 Retail 115,972,280 124,868,554 Government 11,776,346 14,442,747 Corporations 116,001,132 123,637,882 Card receivable 18,704,516 20,119,514 276,377,243 296,441,837 Trading assets 22,638,409 23,829,943 Financial assets designated at FVTPL (*5) 2,228,186 2,344,701 AFS financial assets (*6) 32,822,071 37,186,552 HTM financial assets (*7) 19,805,084 24,990,680 Derivative assets 3,002,859 3,400,178 Other financial assets (*1)(*2) 13,975,889 12,041,304 Financial guarantee contracts 3,424,022 3,267,707 Loan commitments and other credit liabilities 76,055,306 75,518,079 W 450,329,069 479,020,981 (*1) The maximum exposure amounts for due from banks, loans and other financial assets are measured as net of allowances.

Under the guidelines set forth by the Financial Supervisory Commission of Korea, all major commercial banks in Korea, including Shinhan Bank, follow the standardized approach under Basel III for purposes of computing Bank of International Settlement (BIS) ratios for risk classifications of loans to banks and governments. Under this standardized approach under Basel III, risk classification for loans to banks and governments are determined on the basis of sovereign credit ratings, and not internal credit ratings assigned by the lending bank that are specific to the individual banks and governments. More specifically, this approach involves classifying loans to banks and governments in a given jurisdiction as either Grade 1 or Grade 2 based on the sovereign credit ratings for the government of such jurisdiction as determined by the Organization for Economic Co-operation (*2) The Group holds collateral against due from banks and loans to customers in the form of mortgage interests over property, other registered securities over assets, and guarantees.

Interest rate risk from non- Foreign exchange risk arises from the Group’s assets and liabilities which are denominated in currencies other than Korean won. The Group’s market risks arise primarily from Shinhan Bank, and to a lesser extent, Shinhan Investment, which incurs market risk relating to its trading activities. Shinhan Bank’s Risk Policy Committee acts as the executive decision making body in relation to market risks setting the risk management policies and risk limits and controlling market risks arising from trading and non-trading Shinhan Investment’s Risk Management Working Committee is the executive decision-making body for managing market risks related to Shinhan Investment, and determines, among other things, Shinhan Investment’s overall market risk management policies and strategies, and assesses and approves trading activities and limits. In addition, Shinhan Investment’s Risk Management Department manages various market risk limits and monitors operating conditions on an independent basis from Shinhan Investment’s operating departments. i) Market risk management from trading positions Trading activities are to realize short-term trading profits in debt and stock markets and foreign exchange markets based on short-term forecast of changes in market situation and profits from arbitrage transactions in derivatives such as swap, forward, futures and option transactions. The Group manages market risk related to its trading positions using VaR, market value-based tool. Shinhan Bank currently uses ten-day pre-set Shinhan Investment currently uses the ten-day Value-at-risk • VaR estimates possible losses over a certain period at a particular confidence level using past market movement data. Past market movement, however, is not necessarily a reliable indicator of future events, particularly those that are extreme in nature; • VaR may underestimate the probability of extreme market movements; • Shinhan Bank’s VaR models assume that a holding period of generally one to ten days is sufficient prior to liquidating the underlying positions, but such assumption regarding the length of the holding period may prove to be inadequate; • The 99.9% confidence level does not take into account or provide indication of any losses that might occur beyond this confidence level; and • VaR does not capture all complex effects of various risk factors on the value of positions and portfolios and could underestimate potential losses In order to streamline such differences and use a consistent VaR among operating subsidiaries, the Group has adopted starting in 2013 a unified group-wide market risk measurement methodology, which uses the ten-day An analysis of the Group’s requisite capital in light of the market risk for trading positions as of and for the years ended December 31, 2016 and 2017 based on the standard guidelines for risk management promulgated by the Financial Supervisory Service, was as follows: 2016 Average Maximum Minimum December 31 Interest rate W 376,486 422,592 348,686 422,592 Stock price 159,555 191,957 134,595 134,595 Foreign exchange 132,802 139,694 124,046 132,225 Option volatility 6,078 9,214 2,707 9,215 W 674,921 763,457 610,034 698,627 2017 Average Maximum Minimum December 31 Interest rate W 431,065 463,340 414,689 415,139 Stock price 186,652 225,553 157,730 199,041 Foreign exchange 113,208 121,041 105,823 121,041 Option volatility 10,405 12,599 7,809 12,599 W 741,330 822,533 686,051 747,820 Shinhan Life Insurance was excluded when the Group estimated the market risk, because insurance company was not included in the Group’s subsidiaries for the consolidated BIS capital ratio.

Through its asset and liability management system, Shinhan Bank measures and manages its interest rate risk based on various analytical measures such as interest rate gap, duration gap and net present value and net interest income simulations, and monitors on a monthly basis its interest rate VaR limits, interest rate earnings at risk (“EaR”) limits and interest rate gap ratio limits.

Disclosure of significant estimate and judgment [Abstract]
Significant estimate and judgment	5. Significant estimate and judgment The preparation of consolidated financial statements requires the application of certain critical accounting judgments and assumptions relative to the future. Management’s estimate of the outcome may differ from an actual outcome if managements’ estimate and assumption based on its best judgment at the reporting date are different from an actual environment. The change in an accounting estimate is recognized prospectively in profit or loss in the year of the change, if the change affects that year only, or the year of the change and future years, if the change affects both. (a) Goodwill The Group assesses annually whether any objective evidence of impairment on goodwill exists in accordance with the accounting policy as described in note 3. The recoverable amount of an asset or cash-generating unit is the greater of its value in use and its fair value less costs to sell. Value in use is measured based on estimates. (b) Income taxes The Group is subject to tax law from various countries. Within the normal business process, there are various types of transaction and different accounting method that may add uncertainties to the decision of the final income taxes. Deferred tax is recognized, using the asset-liability method, in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. A deferred tax liability is recognized for taxable temporary differences and a deferred tax asset is recognized for deductible temporary differences to the extent that it is probable that taxable profit will be available against which they can be utilized and the taxable profit will be created in appropriate periods. However, actual income tax in the future may not be identical to the recognized deferred tax assets and liabilities, and this difference can affect current and deferred tax at the year when the final tax effect is finalized. (c) Fair value of financial instruments The fair values of financial instruments which are not actively traded in the market are determined by using valuation techniques. The Group determines valuation method and assumptions based on significant market conditions at the end of each reporting year. Diverse valuation techniques are used to determine the fair value of financial instruments, from general market accepted valuation model internally developed valuation model that incorporates various types of assumptions and variables. (d) Allowances for loan losses, guarantees and unused loan commitments The Group determines and recognizes allowances for losses on loans through impairment testing and recognizes provision for guarantees and unused loan commitments. The accuracy of provisions of credit losses is determined by the methodology and assumptions used for estimating expected cash flows of the borrower for allowances on individual loans and collectively assessing allowances for groups of loans, guarantees and unused loan commitments. (e) Defined benefit obligation The present value of defined benefit obligation that is measured by actuarial valuation method uses various assumptions which can change according to various elements. The rate used to discount post-employment benefit obligations is determined by reference to market yields at the end of the reporting year on high quality corporate bonds. The currency and term of the corporate bonds are consistent with the currency and estimated term of the post-employment benefit obligations. Actuarial gains and losses including experience adjustments and the effects of changes in actuarial assumptions are recognized in other comprehensive income or loss. Other significant assumptions related to defined benefit obligation are based on current market situation. (f) Impairment of available-for-sale When there is a significant or prolonged decline in the fair value of an investment in an equity instrument below its original cost, there is objective evidence that available-for-sale (g) Hedging relationship The hedging instruments are expected to be “highly effective” in offsetting the changes in the fair value or cash flows of the respective hedged items during the period. For a cash flow hedge of a forecasted transaction, the transaction should be highly probable to occur and should present an exposure to variations in cash flows that could ultimately affect reported net income.

(note 49) (*2) The Group recognized full impairment on the goodwill allocated to PT. Shinhan Indo Finance in prior year. iii) Goodwill impairment test The recoverable amounts of each CGU were evaluated based on their respective value in use. • Explanation on evaluation method The income approach was applied when evaluating the recoverable amounts based on value in use, considering the characteristics of each unit or group of CGU. • Projection period When evaluating the value in use, 5.5 years of cash flow estimates – July 1, 2017 through December 31, 2022 – was used in projection and the value thereafter was reflected as terminal value. In case of Shinhan Life Insurance, only the 30 years of future cash flows were applied since the present value of the future cash flows thereafter is not significant. • Discount rates and terminal growth rates The required rates of return expected by shareholders were applied to the discount rates by calculating the cost of capital which comprises a risk-free interest rate, a market risk premium and systemic risk (beta factor). Expected terminal growth rate is on the basis of inflation rates. Discount rates and terminal growth rates applied to each CGU are as follows: Discount rates Terminal growth rate Banking 6.6%~13.5% 0.7%~3.4% Credit card 7.6% 1.7% Securities 11.3%, 12,9% 3.4% Life insurance 8.5% — Others 9.4%, 12.0% 1.7% iv) Key assumptions Key assumptions used in the discounted cash flow calculations of CGUs (other than Shinhan Life Insurance) are as follows: 2017 2018 2019 2020 2021 2022 and CPI growth 1.9 % 1.7 % 1.5 % 1.6 % 1.7 % 1.7 % Real retail sales growth 2.5 % 2.1 % 1.9 % 2.0 % 2.2 % 2.2 % Real GDP growth 2.9 % 2.3 % 1.9 % 2.6 % 2.8 % 2.8 % Key assumptions used in the discounted cash flow calculations of Shinhan Life Insurance are as follows: Key assumptions Rate of return on investment 3.15 % Risk-based capital ratio 204.70 % The values for the CPI growth rate, real retail sales growth rate, real GDP growth rate, rate of return on investment and risk-based capital ratio are based on a combination of internal and external analysis. v) Total recoverable amount and total carrying value of CGUs to which goodwill has been allocated, are as follows: Amount Total recoverable amount W 42,196,357 Total carrying value(*) 37,160,566 W 5,035,791 (*) The goodwill recognized at the acquisition of the retail business of ANZ Vietnam is excluded from the table as the measurement of the fair value of assets acquired and liabilities assumed are not completed (see Note 49).

Insurance liabilities [Abstract]
Liability under insurance contracts	28. Liability under insurance contracts (a) Insurance risk Insurance risk, arising out of underwriting of insurance contract and benefit payment, means a risk in which the amount from an unexpected loss is larger than the premium amount. Insurance risk management aims to minimize risk, of benefit to be paid in excess of what was initially assumed at the time of pricing due to occurrence of an unusual occasion or change of economic environment. The insurance products that the Group provides are life insurance products and can be categorized as individual insurance and group insurance with regard to the insured person. In group insurance contacts the insured person is an employee or member of an entity and the policy holder is either the entity or a representative of the entity. The group insurances comprise savings insurances and protection type insurances. The protection type insurance means an insurance in which the aggregate of the insurance proceeds payable upon survival under the base age condition, cases where a male at the full age of 40 purchases an insurance policy, shall not exceed insurance premiums already paid. The savings insurance means an insurance, other than a protection type insurance product, in which the aggregate of insurance proceeds payable upon survival may exceed insurance premiums already paid. Individual insurances comprise death insurances (in which the insurance event is death), pure endowment insurances (in which the insurance event is survival) and endowment insurances (in which the insurance event is both survival and death). (b) Insurance risk management Insurance risk management comprises acceptance and administration of insurance contracts, calculation and adjustment of premium rate, review and payment of claims, reinsurance and closing accounts. Each insurance component is managed by a department operating for the risk component. The Risk Management Team and other related departments conduct preemptive risk management when they develop or revise an insurance product. Insurance risk is continuously improved through regularly reviewing experience rate analysis, insurance risk measurement, underwriting and claims inspection process after product selling. i) Underwriting The Group reviews and improves the medical underwriting guideline based on the changes of medical environment. The Group reassesses and reinforces underwriting standards through profit and loss analysis over insurance contracts. Consultants are updated with the latest underwriting standards. The Group distributes underwriting manual for consultants to prevent mis-selling. ii) Risk management through reinsurance The Group cedes an insurance contract to reinsurer if risks of the contract need to be transferred or diversified to ensure claims payment ability and to maintain financial sustainability of the Group. To achieve the objectives of reinsurance activity, the Group runs reinsurance business efficiently by profit-loss analysis, cedes insurance contracts to reliable reinsurer and observes relevant regulations through the internal control system. iii) Developing insurance product When an insurance product is developed or revised, the Group prices insurance premium based on the analysis of expected and actual insurance risk difference and sensitivity to the risk factors. The Group also reviews the appropriateness of the premium and the profitability of the products through the historical loss experience analysis. The Group reviews compliance of risk management policy and appropriateness of expected profit-loss based on experience rate as a part of post selling risk management for a high risk product. Policy and underwriting standard of the product would be revised in line with the result of the review to improve insurance risk. iv) Assessment of claims requests and payment A standard process for accepting requests and claims payment is enacted to regulate the assessment process of claims requests. The Group pays reasonable benefit using insurance risk management system score, assessment process by types of claims and historical insurance loss experience analysis. The Group monitors deficiency of insurance policy through claim assessment process, and based on that, modifies insurance policies and contracts. The claims payment process is continuously improved reflecting the result of insurance event inspection process monitoring, internal audit and customer complaints etc. (c) Insurance liabilities as of December 31, 2016 and 2017 are as follows: 2016 2017 Policy reserve W 22,366,865 24,515,364 Policyholder’s equity adjustment 10,569 (76 ) W 22,377,434 24,515,288 (d) Policy reserve as of December 31, 2016 and 2017 are as follows: 2016 2017 Interest rate linked W 15,177,891 16,464,193 Fixed interest rate 7,188,974 8,051,171 W 22,366,865 24,515,364 (e) The details of policy reserves as of December 31, 2016 and 2017 are as follows: 2016 Individual insurance Group insurance Pure Death Endowment Subtotal Pure protection Savings Subtotal Total Premium reserve W 4,848,027 9,451,671 6,958,191 21,257,889 37,777 297 38,074 21,295,963 Guarantee reserve 11,265 44,288 156 55,709 — — — 55,709 Unearned premium reserve 3 376 — 379 465 — 465 844 Reserve for outstanding claims 79,017 714,129 155,735 948,881 29,788 — 29,788 978,669 Interest rate difference guarantee reserve 1,882 163 13 2,058 — — — 2,058 Mortality gains reserve 6,212 5,275 222 11,709 4 — 4 11,713 Interest gains reserve 17,356 268 21 17,645 — — — 17,645 Long term duration dividend reserve 56 10 2 68 — — — 68 Reserve for policyholder’s profit dividend 2,862 — — 2,862 — — — 2,862 Reserve for losses on dividend insurance contract 1,334 — — 1,334 — — — 1,334 W 4,968,014 10,216,180 7,114,340 22,298,534 68,034 297 68,331 22,366,865 2017 Individual insurance Group insurance Pure Death Endowment Subtotal Pure Savings Subtotal Total Premium reserve W 5,343,670 10,628,661 7,323,183 23,295,514 32,538 57 32,595 23,328,109 Guarantee reserve 11,678 50,615 151 62,444 — — — 62,444 Unearned premium reserve 3 364 — 367 652 — 652 1,019 Reserve for outstanding claims 98,596 784,535 176,566 1,059,697 26,068 — 26,068 1,085,765 Interest rate difference guarantee reserve 2,280 159 12 2,451 — — — 2,451 Mortality gains reserve 7,736 5,195 200 13,131 5 — 5 13,136 Interest gains reserve 18,463 268 20 18,751 — — — 18,751 Long term duration dividend reserve 59 10 1 70 — — — 70 Reserve for policyholder’s profit dividend 2,374 — — 2,374 — — — 2,374 Reserve for losses on dividend insurance contract 1,245 — — 1,245 — — — 1,245 W 5,486,104 11,469,807 7,500,133 24,456,044 59,263 57 59,320 24,515,364 (f) Reinsurance credit risk as of December 31, 2016 and 2017 are as follows: 2016 Reinsurance Reinsurance AA- W 930 2,377 A- 820 1,692 W 1,750 4,069 2017 Reinsurance Reinsurance AA- W 1,893 3,420 A- 1,217 3,387 W 3,110 6,807 (g) Income or expenses on insurance for the years ended December 31, 2015, 2016 and 2017 are as follows: 2015 2016 2017 Insurance income: Premium income W 4,421,381 4,558,453 4,550,277 Reinsurance income 4,239 6,840 10,532 Separate account income 22,208 20,805 38,999 4,447,828 4,586,098 4,599,808 Insurance expenses: Claims paid (1,946,669 ) (2,007,831 ) (2,213,285 ) Reinsurance premium expenses (5,306 ) (8,405 ) (13,220 ) Provision for policy reserves (2,277,549 ) (2,325,010 ) (2,147,139 ) Separate account expenses (22,207 ) (20,805 ) (38,999 ) Discount charge (458 ) (548 ) (632 ) Acquisition costs (596,124 ) (559,213 ) (543,752 ) Collection expenses (14,139 ) (15,367 ) (15,716 ) Deferred acquisition costs 418,975 373,490 336,851 Amortization of deferred acquisition costs (436,512 ) (440,913 ) (423,955 ) (4,879,989 ) (5,004,602 ) (5,059,847 ) Net loss on insurance W (432,161 ) (418,504 ) (460,039 ) (h) Maturity of premium reserve as of December 31, 2016 and 2017 are as follows: 2016 Less than 1 ~ 3 3 ~ 7 7 ~ 10 10 ~ 20 More than Total Fixed interest rate W 25,096 175,097 549,783 598,030 1,186,510 4,026,275 6,560,791 Interest rate linked 38,828 220,839 1,711,187 469,287 1,227,833 11,067,198 14,735,172 Ending balance W 63,924 395,936 2,260,970 1,067,317 2,414,343 15,093,473 21,295,963 2017 Less than 1 ~ 3 3 ~ 7 7 ~ 10 10 ~ 20 More than Total Fixed interest rate W 62,611 256,126 646,634 550,935 1,227,656 4,629,667 7,373,629 Interest rate linked 32,364 660,966 1,549,321 384,276 1,359,071 11,968,482 15,954,480 Ending balance W 94,975 917,092 2,195,955 935,211 2,586,727 16,598,149 23,328,109 (i) Liability adequacy test, LAT Liability adequacy tests were performed on the premium reserve, unearned premium reserve and guarantee reserve for the contracts held at December 31, 2016 and 2017.

Interests in unconsolidated structured entities	48. Interests in unconsolidated structured entities (a) The nature and extent of interests in unconsolidated structured entities The Group is involved in assets-backed securitization, structured financing, beneficiary certificates and other structured entities and characteristics of these structured entities are as follows: Description Assets-backed securitization Securitization vehicles are established to buy assets from originators and issue asset-backed securities in order to facilitate the originators’ funding activities and enhance their financial soundness. The Group is involved in the securitization vehicles by purchasing (or committing to purchase) the asset-backed securities issued and/or providing other forms of credit enhancement. The Group does not consolidate a securitization vehicle if (i) the Group is unable to make or approve decisions as to the modification of the terms and conditions of the securities issued by such vehicle or disposal of such vehicles’ assets, (ii) (even if the Group is so able) if the Group does not have the exclusive or primary power to do so, or (iii) if the Group does not have exposure, or right, to a significant amount of variable returns from such entity due to the purchase (or commitment to purchase) of asset-backed securities so issued or subordinated obligations or by providing other forms of credit support. Structured financing Structured entities for project financing are established to raise funds and invest in a specific project such as M&A (mergers and acquisitions), BTL (build-transfer-lease), shipping finance, etc. The Group is involved in the structured entities by originating loans, investing in equity, or providing credit enhancement. Investment fund Investment fund means an investment trust, a PEF (private equity fund) or a partnership which invests in a group of assets such as stocks or bonds by issuing a type of beneficiary certificates to raise funds from the general public, and distributes its income and capital gains to their investors. The Group manages assets by investing in shares of investment fund or playing a role of an operator or a GP (general partner) of investment fund, on behalf of other investors.

Basis of preparation	2. Basis of preparation (a) Statement of compliance The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”). IFRS are the standards and related interpretations issued by the International Accounting Standards Board (“IASB”). The consolidated financial statements were authorized for issue by the Board of Directors on February 7, 2018, which will be submitted for approval to the shareholders’ meeting on March 22, 2018. (b) Basis of measurement The consolidated financial statements have been prepared on the historical cost basis except for the following material items in the statement of financial position. • derivative financial instruments are measured at fair value • financial instruments at fair value through profit or loss are measured at fair value • available-for-sale • liabilities for cash-settled share-based payment arrangements are measured at fair value • financial liabilities designated as hedged items in a fair value hedge accounting of which changes in fair value attributable to the hedged risk are recognized in profit or loss • liabilities for defined benefit plans that are recognized at the net of the total present value of defined benefit obligations less the fair value of plan assets (c) Functional and presentation currency The financial statements of the parent and each subsidiary are prepared in functional currency of the respective operation. These consolidated financial statements are presented in Korean won, which is the Parent Company’s functional currency and the currency of the primary economic environment in which the Group operates. (d) Use of estimates and judgments The preparation of the consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are evaluated on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future years affected. In preparing the these consolidated financial statements, the significant judgments made by management in applying the Group’s accounting policies and the key sources of estimation uncertainty were the same as those that applied to the consolidated financial statements as of and for the year ended December 31, 2016, except for the changes below. During 2017, the credit card segment of the Group had accumulated sufficient experience to properly calculate probability of default, loss given default and credit conversion factors by considering the characteristics of borrowers, or its homogeneous borrowing groups, with credit evaluation system and risk evaluation system based on BASEL II; and based on this newly accumulated experience, the calculation methodology of loan losses has been changed from roll rate analysis model to internal model approach. As a result of changes in accounting estimates described above, allowances for loan losses and provision for unused credit lines decreased by W W (e) Changes in accounting policies The Group applied for the first time certain standards and amendments, which are effective for annual periods beginning on or after January 1, 2017. 1) Amendments to IAS 7, ‘Statement of Cash Flows’ The Group applied amendments to IAS 7, ‘ Statement of Cash Flows 2) Amendments to IAS 12, ‘Income Taxes’ The Group applied amendments to IAS 12, ‘ Income Taxes 3) Amendments to IFRS 12, ‘Disclosure of Interests in Other Entities’ The Group applied amendments to IFRS 12, ‘ Disclosure of Interests in Other Entities

Disclosure of significant accounting policies [Abstract]
Operating segments	(a) Operating segments 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 CEO to make decisions about resources to be allocated to the segment and assess its performance, and for which discrete financial information is available. Segment results that are reported to the CEO include items directly attributable to a segment as well as those that can be allocated on a reasonable basis. The Group’s reportable segments consist of banking, credit card, securities, life insurance, and others.
Basis of consolidation	(b) Basis of consolidation i) Subsidiaries Subsidiaries are entities controlled by the Group. The Group controls an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. The financial statements of subsidiaries are included in the consolidated financial statements from the date on which control commences until the date on which control ceases. If a member of the Group uses accounting policies other than those adopted in the consolidated financial statements for the same transactions and events in similar circumstances, appropriate adjustments are made to its financial statements in preparing the consolidated financial statements. ii) Structured entity The Group establishes or invests in various structured entities. A structured entity is an entity designed so that its activities are not governed by way of voting rights. When assessing control of a structured entity, the Group considers factors such as the purpose and the design of the investee; its practical ability to direct the relevant activities of the investee; the nature of its relationship with the investee; and the size of its exposure to the variability of returns of the investee. The Group does not recognize any non-controlling iii) Intra-group transactions Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated in preparing the consolidated financial statements. Intra-group losses are recognized as expense if intra-group losses indicate an impairment that requires recognition in the consolidated financial statements. iv) Non-controlling Non-controlling non-controlling non-controlling
Business combinations	(c) Business combinations i) Business combinations A business combination is accounted for by applying the acquisition method, unless it is a combination involving entities or businesses under common control. Each identifiable asset and liability is measured at its acquisition-date fair value except for below: • Leases and insurance contracts are required to be classified on the basis of the contractual terms and other factors • Only those contingent liabilities assumed in a business combination that are a present obligation and can be measured reliably are recognized • Deferred tax assets or liabilities are recognized and measured in accordance with IAS 12 Income Taxes • Employee benefit arrangements are recognized and measured in accordance with IAS 19 Employee Benefits • Indemnification assets are recognized and measured on the same basis as the indemnified liability or asset • Reacquired rights are measured on the basis of the remaining contractual terms of the related contract • Liabilities or equity instruments related to share-based payment transactions are measured in accordance with the method in IFRS 2 Share-based Payment • Assets held for sale are measured at fair value less costs to sell in accordance with IFRS 5 Non-current As of the acquisition date, non-controlling non-controlling The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the acquisition-date fair values of the assets transferred by the acquirer, the liabilities incurred by the acquirer to former owners of the acquiree and the equity interests issued by the acquirer. However, any portion of the acquirer’s share-based payment awards exchanged for awards held by the acquiree’s employees that are included in consideration transferred in the business combination shall be measured in accordance with the method described above rather than at fair value. Acquisition-related costs are costs the acquirer incurs to effect a business combination. Those costs include finder’s fees; advisory, legal, accounting, valuation and other professional or consulting fees; general administrative costs, including the costs of maintaining an internal acquisitions department; and costs of registering and issuing debt and equity securities. Acquisition-related costs, other than those associated with the issue of debt or equity securities, are expensed in the periods in which the costs are incurred and the services are received. The costs to issue debt or equity securities are recognized in accordance with IAS 32 Financial Instruments: Presentation Financial Instruments: Recognition and Measurement ii) Goodwill The Group measures goodwill at the acquisition date as: • the fair value of the consideration transferred; plus • the recognized amount of any non-controlling • if the business combination is achieved in stages, the fair value of the pre-existing • the net recognized amount (generally fair value) of the identifiable assets acquired and liabilities assumed. When the excess is negative, bargain purchase gain is recognized immediately in profit or loss. When the Group additionally acquires non-controlling
Investments in associates and joint ventures	(d) Investments in associates and joint ventures An associate is an entity in which the Group has significant influence, but not control, over the entity’s financial and operating policies. Significant influence is presumed to exist when the Group holds between 20 and 50 percent of the voting power of another entity. A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the arrangement. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control. The investment in an associate and a joint venture is initially recognized at cost, and the carrying amount is increased or decreased to recognize the Group’s share of the profit or loss and changes in equity of the associate and the joint venture after the date of acquisition. Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated in preparing the consolidated financial statements. Intra-group losses are recognized as expense if intra-group losses indicate an impairment that requires recognition in the consolidated financial statements. If an associate or a joint venture uses accounting policies different from those of the Group for like transactions and events in similar circumstances, appropriate adjustments are made to its financial statements in applying the equity method. When the Group’s share of losses exceeds its interest in an equity accounted investee, the carrying amount of that interest, including any long-term investments, is reduced to nil and the recognition of further losses is discontinued except to the extent that the Group has an obligation or has to make payments on behalf of the investee for further losses.
Cash and cash equivalents	(e) Cash and cash equivalents Cash and cash equivalents comprise cash balances and demand deposits with maturities of three months or less from the acquisition date that are subject to an insignificant risk of changes in their fair value, and are used by the Group in the management of its short-term commitments.
Non-derivative financial assets	(f) Non-derivative The Group recognizes and measures non-derivative held-to-maturity available-for-sale Upon initial recognition, non-derivative i) Financial assets at fair value through profit or loss A financial asset is classified as at fair value through profit or loss if it is held for trading or is designated at fair value through profit or loss. Upon initial recognition, transaction costs are recognized in profit or loss when incurred. Financial assets at fair value through profit or loss are measured at fair value, and changes therein are recognized in profit or loss. A financial asset other than a financial asset held for trading may be designated as at fair value through profit or loss (“FVTPL”) upon initial recognition if: • such designation eliminates or significantly reduces a recognition or measurement inconsistency that would otherwise arise; or • the financial asset forms part of a group of financial assets or financial liabilities or both, which is managed and its performance is evaluated on a fair value basis, in accordance with the Group’s documented risk management or investment strategy, and information about the grouping is provided internally on that basis; or • it forms part of a contract containing one or more embedded derivatives that would be required to be separated from the host contract. ii) Held-to-maturity A non-derivative held-to-maturity held-to-maturity iii) Loans and receivables Loans and receivables are financial assets with fixed or determinable payments that are not quoted in an active market. Subsequent to initial recognition, loans and receivables are measured at amortized cost using the effective interest method. iv) Available-for-sale Available-for-sale non-derivative available-for-sale held-to-maturity v) De-recognition The Group derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows on the financial asset in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred. Any interest in transferred financial assets that is created or retained by the Group is recognized as a separate asset or liability. If the Group retains substantially all the risks and rewards of ownership of the transferred financial assets, the Group continues to recognize the transferred financial assets and recognizes financial liabilities for the consideration received. vi) Offsetting between financial assets and financial liabilities Financial assets and financial liabilities are offset and the net amount is presented in the consolidated statement of financial position only when the Group currently has a legally enforceable right to offset the recognized amounts, and there is the intention to settle on a net basis or to realize the asset and settle the liability simultaneously.
Derivative financial instruments including hedge accounting	(g) Derivative financial instruments including hedge accounting Derivatives are initially recognized at fair value. Subsequent to initial recognition, derivatives are measured at fair value, and changes therein are accounted for as described below. i) Hedge accounting The Group holds forward exchange contracts, interest rate swaps, currency swaps and other derivative contracts to manage interest rate risk and foreign exchange risk. The Group designated derivatives as hedging instruments to hedge the risk of changes in the fair value of assets, liabilities or firm commitments (a fair value hedge) and foreign currency risk of highly probable forecasted transactions or firm commitments (a cash flow hedge). On initial designation of the hedge, the Group formally documents the relationship between the hedging instrument(s) and hedged item(s), including the risk management objectives and strategy in undertaking the hedge transaction, together with the methods that will be used to assess the effectiveness of the hedging relationship. • Fair value hedge • Cash flow hedge • Hedge of net investment The Effects of Changes in Foreign Exchange Rates ii) Separable embedded derivatives Embedded derivatives are separated from the host contract and accounted for separately only if the following criteria has been met: (a) the economic characteristics and risks of the embedded derivative are not closely related to those of the host contract; (b) a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and (c) the hybrid instrument is not measured at fair value with changes in fair value recognized in profit or loss. Changes in the fair value of separable embedded derivatives are recognized immediately in profit or loss. iii) Other derivative financial instruments Changes in the fair value of other derivative financial instrument not designated as a hedging instrument are recognized immediately in profit or loss. iv) Unobservable valuation differences at initial recognition Any difference between the fair value of over the counter derivatives at initial recognition and the amount that would be determined at that date using a valuation technique in a situation in which the valuation is dependent on unobservable parameters is not recognized in profit or loss but is recognized on a straight-line basis over the life of the instrument or immediately when the fair value becomes observable.
Impairment of financial assets	(h) Impairment of financial assets A financial asset not carried at fair value through profit or loss is assessed at each reporting date to determine whether there is objective evidence that it is impaired. A financial asset is impaired if objective evidence indicates that a loss event has occurred after the initial recognition of the asset, and that the loss event had a negative effect on the estimated future cash flows of that asset that can be estimated reliably. However, losses expected as a result of future events, regardless of likelihood, are not recognized. In addition, for an investment in an equity security, a significant or prolonged decline in its fair value below its cost is objective evidence of impairment. If financial assets have objective evidence that they are impaired, impairment losses should be measured and recognized. Objective evidence that a financial asset or group of assets is impaired includes observable data that comes to the attention of the holder of the asset about the following loss events: • significant financial difficulty of the issuer or obligor • a breach of contract, such as a default or delinquency in interest or principal payments; • the lender, for economic or legal reasons relating to the borrower’s financial difficulty, granting to the borrower a concession that the lender would not otherwise consider • it becoming probable that the borrower will enter bankruptcy or other financial reorganization • the disappearance of an active market for that financial asset because of financial difficulties • observable data indicating that there is a measurable decrease in the estimated future cash flows from a group of financial assets since the initial recognition of those assets, although the decrease cannot yet be identified with the individual financial assets in the group. i) Loans and receivables The Group first assesses whether objective evidence of impairment exists individually for loans and receivables that are individually significant, and individually or collectively for financial assets that are not individually significant. If the Group determines that no objective evidence of impairment exists for an individually assessed financial asset, whether significant or not, it includes the asset in a group of financial assets with similar credit risk characteristics and collectively assesses them for impairment. Assets that are individually assessed for impairment and for which an impairment loss is or continues to be recognized are not included in a collective assessment of impairment. If there is objective evidence that an impairment loss on loans and receivables has been incurred, the amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset’s original effective interest rate (i.e., the effective interest rate computed at initial recognition). If the interest rate of a loan or receivable is a floating rate, the discount rate used to evaluate impairment loss is the current effective interest rate defined in the loan agreement. The present value of estimated future cash flows of secured financial assets is calculated by including cash flows from collateral after deducting costs to acquire and sell the collateral. In assessing collective impairment, the Group rates and classifies financial assets, based on credit risk assessment or credit rating assessment process that takes into account asset type, industry, regional location, collateral type, delinquency and other relative factors. Future cash flow of financial assets applicable to collective impairment assessment is estimated by using statistical modeling of historical trends of the probability of default, timing of recoveries and the amount of loss incurred, adjusted for management’s judgment as to whether current economic and credit conditions are such that the impairment losses are likely to be greater or less than suggested by historical modeling. In adjusting the future cash flow by historical modeling, the result has to be in line with changes and trends of observable data. Methodologies and assumptions used to estimate future cash flow are evaluated on a regular basis in order to reduce any discrepancy between impairment loss estimation and actual loss. Impairment losses are recognized in profit or loss and reflected in an allowance account against loans and receivables. When a subsequent event causes the amount of impairment loss to decrease, and the decrease can be related objectively to an event occurring after the impairment was recognized, the decrease in impairment loss is reversed through profit or loss of the year. ii) Available-for-sale When a decline in the fair value of an available-for-sale available-for-sale available-for-sale iii) Held-to-maturity An impairment loss in respect of held-to-maturity
Property and equipment	(i) Property and equipment Property and equipment are initially measured at cost and after initial recognition, are carried at cost less accumulated depreciation and accumulated impairment losses. The cost of property and equipment includes expenditures arising directly from the construction or acquisition of the asset, any costs directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management and the initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located. Items of property and equipment are measured at cost less accumulated depreciation and accumulated impairment losses. The cost of replacing a part of an item of property or 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, where the carrying amount of the replaced part is derecognized. The cost of the day to day servicing of property and equipment are recognized in profit or loss as incurred. Property and equipment are depreciated on a straight-line basis over the estimated useful lives, which most closely reflect the expected pattern of consumption of the future economic benefits embodied in the asset. Leased assets under finance lease are depreciated over the shorter of the lease term and their useful lives. The estimated useful lives for the current and comparative years are as follows: Descriptions Depreciation method Useful lives Buildings Straight-line 40 years Other properties Straight-line 4~5 years Depreciation methods, useful lives and residual value are reassessed at each fiscal year-end
Intangible assets	(j) Intangible assets Intangible assets are measured initially at cost and, subsequently, are carried at cost less accumulated amortization and accumulated impairment losses. Amortization of intangible assets except for goodwill is calculated on a straight-line basis over the estimated useful lives of intangible assets from the date that they are available for use. The residual value of intangible assets is zero. However, as there are no foreseeable limits to the periods over which club memberships are expected to be available for use, this intangible asset is determined as having indefinite useful lives and not amortized. Descriptions Useful lives Software, capitalized development cost 5 years Other intangible assets 5 years or contract periods Amortization periods and the amortization methods for intangible assets with finite useful lives are reviewed at the end of each reporting period. The useful lives of intangible assets that are not being amortized are reviewed at the end of each reporting period to determine whether events and circumstances continue to support indefinite useful life assessments for those assets. Changes are accounted for as changes in accounting estimates. i) Research and development Expenditures on research activities, undertaken with the prospect of gaining new technical knowledge and understanding, are recognized in profit or loss as incurred. Development expenditures are capitalized only if development costs can be measured reliably, the product or process is technically and commercially feasible, future economic benefits are probable, and the Group intends to and has sufficient resources to complete development and to use or sell the asset. Other development expenditures are recognized in profit or loss as incurred. ii) Subsequent expenditures Subsequent expenditures are capitalized only when they increase the future economic benefits embodied in the specific asset to which it relates. All other expenditures, including expenditures on internally generated goodwill and brands, are recognized in profit or loss as incurred.
Investment property	(k) Investment property Property held for the purpose of earning rentals or benefiting from capital appreciation is classified as investment property. Investment property is measured initially at its cost. Transaction costs are included in the initial measurement. Subsequently, investment property is carried at depreciated cost less any accumulated impairment losses. The estimated useful lives for the current and comparative years are as follows: Descriptions Depreciation method Useful lives Buildings Straight-line 40 years
Leased assets	(l) Leased assets i) Classification of a lease The Group classifies and accounts for leases as either a finance or operating lease, depending on the terms. Leases where the lessee assumes substantially all of the risks and rewards of ownership are classified as finance leases. All other leases are classified as operating leases. ii) Lessee Under a finance lease, the lessee recognizes the leased asset and a liability for future lease payments. Upon initial recognition the leased asset is measured at an amount equal to the lower of its fair value and the present value of the minimum lease payments. Subsequent to initial recognition, the asset is accounted for in accordance with the accounting policy applicable to that asset. Under an operating lease, the lessee recognizes the lease payments as expense over the lease term and does not recognize the leased asset in its statement of financial position. iii) Lessor Under a finance lease, the lessor recognizes a finance lease receivable. Over the lease term the lessor accrues interest income on the net investment. The receipts under the lease are allocated between reducing the net investment and recognizing finance income, so as to produce a constant rate of return on the net investment. Under an operating lease, the lessor recognizes the lease payments as income over the lease term and the leased asset in its statement of financial position.
Assets held for sale	(m) Assets held for sale Non-current non-current The Group recognizes an impairment loss for any initial or subsequent write-down of an asset (or disposal group) to fair value less costs to sell, and a gain for any subsequent increase in fair value less costs to sell, up to the cumulative impairment loss previously recognized in accordance with IAS 36 Impairment of Assets An asset that is classified as held for sale or part of a disposal group classified as held for sale is not depreciated (or amortized).
Impairment of non-financial assets	(n) Impairment of non-financial The carrying amounts of the Group’s non-financial The Group estimates the recoverable amount of an individual asset. If it is impossible to measure the individual recoverable amount of an asset, then the Group estimates the recoverable amount of cash-generating unit (“CGU”). A CGU is the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. The recoverable amount of an asset or CGU is the greater of its value in use and its fair value less costs to sell. The value in use is estimated by applying a pre-tax An impairment loss is recognized if the carrying amount of an asset or a CGU exceeds its recoverable amount. Impairment losses are recognized in profit or loss. Goodwill acquired in a business combination is allocated to each CGU that is expected to benefit from the synergies arising from the goodwill acquired. Any impairment identified at the CGU level will first reduce the carrying value of goodwill and then be used to reduce the carrying amount of the other assets in the CGU on a pro rata basis. Except for impairment losses in respect of goodwill which are never reversed, an impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized.
Non-derivative financial liabilities	(o) Non-derivative The Group classifies non-derivative i) Financial liabilities at fair value through profit or loss Financial liabilities at fair value through profit or loss include financial liabilities held for trading or designated as such upon initial recognition. Subsequent to initial recognition, financial liabilities at fair value through profit or loss are measured at fair value, and changes therein are recognized in profit or loss. Upon initial recognition, transaction costs that are directly attributable to the acquisition are recognized in profit or loss as incurred. The criteria for designation of financial liabilities at FVTPL upon initial recognition are the same as those of financial assets at FVTPL. ii) Other financial liabilities Non-derivative The Group derecognizes a financial liability from the consolidated statement of financial position when it is extinguished (i.e. when the obligation specified in the contract is discharged, cancelled or expires).
Foreign currency	(p) Foreign currency i) Foreign currency transactions Transactions in foreign currencies are translated to the respective functional currencies of Group entities at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the reporting date are retranslated to the functional currency at the exchange rate at that date. The foreign currency gain or loss on monetary items is the difference between amortized cost in the functional currency at the beginning of the period, adjusted for effective interest and payments during the period, and the amortized cost in foreign currency translated at the exchange rate at the end of the reporting period. Non-monetary Foreign currency differences arising on translation are recognized in profit or loss, except for differences arising on the translation of available-for-sale Non-monetary ii) Foreign operations If the presentation currency of the Group is different from a foreign operation’s functional currency, the financial statements of the foreign operation are translated into the presentation currency using the following methods: The assets and liabilities of foreign operations, whose functional currency is not the currency of a hyperinflationary economy, are translated to presentation currency at exchange rates at the reporting date. The income and expenses of foreign operations are translated to functional currency at exchange rates at the dates of the transactions. Foreign currency differences are recognized in other comprehensive income. Any goodwill arising on the acquisition of a foreign operation and any fair value adjustments to the carrying amounts of assets and liabilities arising on the acquisition of that foreign operation is treated as assets and liabilities of the foreign operation. Thus they are expressed in the functional currency of the foreign operation and translated at the closing rate. When a foreign operation is disposed of, the relevant amount in the translation is transferred to profit or loss as part of the profit or loss on disposal. In any other partial disposal of a foreign operation, the relevant proportion is reclassified to profit or loss. Foreign exchange gains or losses arising from a monetary item receivable from or payable to a foreign operation, the settlement of which is neither planned nor likely to occur in the foreseeable future and which in substance is considered to form part of the net investment in the foreign operation, are recognized in other comprehensive income in the translation reserve. iii) Net investment in a foreign operation If the settlement of a monetary item receivable from or payable to a foreign operation is neither planned nor likely to occur in the foreseeable future, then foreign currency difference arising on the item which in substance is considered to form part of the net investment in the foreign operation, are recognized in the other comprehensive income and shall be reclassified to profit or loss on disposal of the investment.
Equity	(q) Equity i) Capital stock Ordinary shares are classified as equity. Incremental costs directly attributable to the issuance of ordinary shares and share options are recognized as a deduction from equity, net of any tax effects. Preference share capital is classified as equity if it is non-redeemable, Preference share capital is classified as a liability if it is redeemable on a specific date or at the option of the shareholders, or if dividend payments are not discretionary. Dividends thereon are recognized as interest expense in profit or loss as accrued. ii) Hybrid bonds The Group classifies issued financial instruments, or their component parts, as a financial liability or an equity instrument depending on the substance of the contractual arrangement of such financial instruments. Hybrid bonds where the Group has an unconditional right to avoid delivering cash or another financial asset to settle a contractual obligation are classified as equity instruments and presented in equity. iii) Capital adjustments Changes in ownership interests in a subsidiary that do not result in a loss of control, such as the subsequent purchase or sale by a parent of a subsidiary’s equity instruments, are accounted for as equity transactions in capital adjustments.
Employee benefits	(r) Employee benefits i) Short-term employee benefits Short-term employee benefits are employee benefits that are due to be settled within 12 months after the end of the period in which the employees render the related service. When an employee has rendered service to the Group during an accounting period, the Group recognizes the undiscounted amount of short-term employee benefits expected to be paid in exchange for that service. ii) Other long-term employee benefits Other long-term employee benefits include employee benefits that are settled beyond 12 months after the end of the period in which the employees render the related service, and are calculated at the present value of the amount of future benefit that employees have earned in return for their service in the current and prior periods, less the fair value of any related assets. The present value is determined by discounting the expected future cash flows using the interest rate of corporate bonds that have maturity dates approximating the terms of the Group’s obligations and that are denominated in the same currency in which the benefits are expected to be paid. Any actuarial gains and losses are recognized in profit or loss in the period in which they arise. iii) Retirement benefits: defined contribution plans When an employee has rendered service to the Group during a period, the Group recognizes the contribution payable to a defined contribution plan in exchange for that service as a liability (accrued expense), after deducting any contribution already paid. If the contribution already paid exceeds the contribution due for service before the end of the reporting period, the Group recognizes that excess as an asset (prepaid expense) to the extent that the prepayment will lead to a reduction in future payments or a cash refund. iv) Retirement benefits: defined benefit plans A defined benefit plan is a post-employment benefit plan other than a defined contribution plan. The Group’s net obligation in respect of defined benefit plans is calculated by estimating the amount of future benefit that employees have earned in return for their service in the current and prior periods; that benefit is discounted to determine its present value. The fair value of plan assets is deducted. The calculation is performed annually by an independent actuary using the projected unit credit method. Remeasurements of the net defined benefit liability, which comprise actuarial gains and losses, the return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognized immediately in other comprehensive income. The Group determines the net interest expense (income) on the net defined benefit liability (asset) for the period by applying the discount rate used to measure the defined benefit obligation at the beginning of the annual period to the then-net The discount rate is the yield at the reporting date on high-quality corporate bonds that have maturity dates approximating the terms of the Group’s obligations and that are denominated in the same currency in which the benefits are expected to be paid. The Group recognizes service cost and net interest on the net defined benefit liability (asset) in profit or loss and remeasurement of the net defined benefit liability (asset) in other comprehensive income. When the benefits of a plan are changed or when a plan is curtailed, the resulting change in benefit that relates to past service or the gain or loss on curtailment is recognized immediately in profit or loss. The Group recognizes gains and losses on the settlement of a defined benefit plan when the settlement occurs. v) Termination benefits Termination benefits are recognized as an expense when the Group is committed demonstrably, without realistic possibility of withdrawal, to a formal detailed plan to either terminate employment before the normal retirement date, or to provide termination benefits as a result of an offer made to encourage voluntary redundancy. Termination benefits for voluntary redundancies are recognized as an expense if the Group has made an offer of voluntary redundancy, it is probable that the offer will be accepted, and the number of acceptances can be estimated reliably. If benefits are payable more than 12 months after the reporting period, then they are discounted to their present value.
Share-based payment transactions	(s) Share-based payment transactions The grant date fair value of share-based payment awards granted to employees is recognized as an employee expense, with a corresponding increase in equity, over the period that the employees unconditionally become entitled to the awards. The amount recognized as an expense is adjusted to reflect the number of awards for which the related service and non-market non-market non-vesting true-up The fair value of the amount payable to employees in respect of share appreciation rights, which are settled in cash, is recognized as an expense with a corresponding increase in liabilities, over the period that the employees unconditionally become entitled to payment. The liability is remeasured at each reporting date and at settlement date. Any changes in the fair value of the liability are recognized as personnel expense in profit or loss.
Provisions	(t) Provisions A provision is recognized if, as a result of a past event, the Group has a present legal or constructive obligation that can be estimated reliably, and it is probable that an outflow of economic benefits will be required to settle the obligation. The risks and uncertainties that inevitably surround many events and circumstances are taken into account in reaching the best estimate of a provision. Where the effect of the time value of money is material, provisions are determined at the present value of the expected future cash flows. Provisions are reviewed at the end of each reporting period and adjusted to reflect the current best estimate. If it is no longer probable that an outflow of resources embodying economic benefits will be required to settle the obligation, the provision is reversed. Provision shall be used only for expenditures for which the provision was originally recognized.
Financial guarantee contract	(u) Financial guarantee contract A financial guarantee contract is a contract that requires the issuer (the Group) to make specified payments to reimburse the holder for a loss it incurs because a specified debtor fails to make payments when due in accordance with the original or modified terms of a debt instrument. Financial guarantee contracts are initially measured at their fair values and, if not designated as at fair value through profit or loss, are subsequently measured at the higher of: • The amount determined in accordance with IAS 37 Provisions, Contingent Liabilities and Contingent Assets • The initial amount recognized, less, when appropriate, cumulative amortization recognized in accordance with IAS 18. Revenue
Insurance contracts	(v) Insurance contracts Insurance contracts are defined as “a contract under which one party (the insurer) accepts significant insurance risk from another party by agreeing to compensate the policyholder if a specified uncertain future event adversely affects the policyholder”. A contract that qualifies as an insurance contract remains an insurance contract until all rights and obligations are extinguished or expire. Such a contract that does not contain significant insurance risk is classified as an investment contract and is within the scope of IAS 39, Financial Instruments Recognition and Measurement Insurance Contracts i) Reserves for insurance contracts The Group accounts for insurance contracts based on the Insurance Business Law and other related Insurance Supervisory Regulation. These insurance contracts are calculated based on insurance terms, premium and policy reserves approved by the Financial Supervisory Commission, as follows: • Premium reserve • Unearned premium reserve • Guarantee reserve • Reserve for outstanding claims • Estimated amount: The expenses to be incurred in the course of settlement of the insured event, such as lawsuit or arbitration (if partial amount is settled, the remainder is recognized) • Reserve for ineffective contracts: Reserve for ineffective contracts due to default in premium payment (Partial amount of surrender value) • Unpaid claims: The amount of claims, surrender value and dividend to be paid is determined but not paid yet • IBNR (Incurred But Not Reported): Estimated amount using a statistical method considering the company’s experience rate • Reserve for participating policyholder’s dividend – ii) Policyholders’ equity adjustment At year end, unrealized holding gains and losses on available-for-sale non-participating iii) Liability adequacy test (the “LAT”) Liability adequacy tests are performed by the Group in order to ensure the adequacy of the contract liabilities, net of related deferred acquisition costs and deferred policyholders’ participation liability or asset. iv) Reinsurance contracts According to IFRS 4, “ Insurance Contracts 1) reinsurance assets against the related insurance liabilities; or 2) income or expense from reinsurance contracts against the expense or income from the related insurance contracts. If reinsurance assets are determined to be impaired, impairment loss is recognized in the profit and loss for the current period. v) Deferred acquisition costs (the “DAC”) Policy acquisition costs, which include commissions, certain direct and incremental underwriting and agency expenses associated with acquiring insurance policies, are deferred and amortized using the straight-line method over the contract year, up to seven years. Actual acquisition costs incurred in excess of estimated acquisition costs are expensed.
Financial income and expense	(w) Financial income and expense i) Interest Interest income and expense are recognized in profit or loss using the effective interest method. The effective interest rate is the rate that exactly discounts the estimated future cash payments and receipts through the expected life of the financial asset or liability (or, where appropriate, a shorter year) to the carrying amount of the financial asset or liability. When calculating the effective interest rate, the Group estimates future cash flows considering all contractual terms of the financial instrument, but not future credit losses. The calculation of the effective interest rate includes all fees and points paid or received that are an integral part of the effective interest rate. Transaction costs include incremental costs that are directly attributable to the acquisition or issue of a financial asset or liability. Once an impairment loss has been recognized on a loan, although the accrual of interest in accordance with the contractual terms of the instrument is discontinued, interest income is recognized at the rate of interest that was used to discount estimated future cash flows for the purpose of measuring the impairment loss. ii) Fees and commission Fees and commission income and expense that are integral to the effective interest rate on a financial asset or liability are included in the measurement of the effective interest rate. Fees and commission income, including account servicing fees, investment management fees, sales commission, placement fees and syndication fees, are recognized as the related services are performed. When a loan commitment is not expected to result in the draw-down of a loan, the related loan commitment fees are recognized on a straight-line basis over the commitment period. Fees and commission expense relate mainly to transaction and service fees, which are expensed as the services are received. iii) Insurance Income The Group recognizes insurance income for the insurance premium paid of which the payment date arrived by the premium payment methods of the insurance contract; and recognizes advance receipts for the insurance premium paid of which the payment date has not arrived at the end of the reporting period. iv) Dividends Dividend income is recognized when the right to receive income is established.
Customer loyalty program	(x) Customer loyalty program For customer loyalty programmes, the fair value of the consideration received or receivable in respect of the initial sale is allocated between award credits (“points”) and other components of the fee and commission income. The Group provides awards, in the form of price discounts and by offering a variety of gifts. The fair value allocated to the points is estimated by reference to the fair value of the monetary and/or non-monetary A provision for onerous contracts is recognized when the expected benefits to be derived by the Group from customer loyalty programmes are lower than the unavoidable cost of meeting its obligations under the programmes.
Income tax	(y) Income tax Income tax expense comprises current and deferred tax. Current tax and deferred tax are recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or in other comprehensive income. i) Current tax Current tax is the expected tax payable or receivable on the taxable profit or loss for the year, using tax rates enacted or substantively enacted at the end of the reporting period and any adjustment to tax payable in respect of previous years. The taxable profit is different from the accounting profit for the period since the taxable profit is calculated excluding the temporary differences, which will be taxable or deductible in determining taxable profit (tax loss) of future periods, and non-taxable non-deductible ii) Deferred tax Deferred tax is recognized, using the asset-liability method, in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. A deferred tax liability is recognized for all taxable temporary differences. A deferred tax asset is recognized for all deductible temporary differences to the extent that it is probable that taxable profit will be available against which they can be utilized. However, deferred tax is not recognized for the following temporary differences: taxable temporary differences arising on the initial recognition of goodwill, or the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting profit or loss nor taxable income. The Group files its national income tax return with the Korean tax authorities under the consolidated corporate tax system, which allows it to make national income tax payments based on the combined profits or losses of the Controlling Company and its wholly owned domestic subsidiaries. Deferred taxes are measured based on the future tax benefits expected to be realized in consideration of the expected combined profits or losses of eligible companies in accordance with the consolidated corporate tax system. Consolidated corporate tax amounts, once determined, are allocated to each of the subsidiaries and are used as a basis for the income taxes to be recorded in their separate financial statements. The Group recognizes a deferred tax liability for all taxable temporary differences associated with investments in subsidiaries, associates, and interests in joint ventures, except to the extent that the Group is able to control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. The Group recognizes a deferred tax asset for all deductible temporary differences arising from investments in subsidiaries and associates, to the extent that it is probable that the temporary difference will reverse in the foreseeable future and taxable profit will be available against which the temporary difference can be utilized. The carrying amount of a deferred tax asset is reviewed at the end of each reporting period and reduces the carrying amount to the extent that it is no longer probable that sufficient taxable profit will be available to allow the benefit of part or all of that deferred tax asset to be utilized. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred tax liabilities and deferred tax assets reflects the tax consequences that would follow from the manner in which the Group expects, at the end of the reporting period to recover or settle the carrying amount of its assets and liabilities. Deferred tax assets and liabilities are offset only if the Group has a legally enforceable right to set off current tax assets against current tax liabilities, and the deferred tax assets and the deferred tax liabilities relate to income taxes levied by the same taxation authority on either: the same taxable entity; or different taxable entities which intend either to settle current tax liabilities and assets on a net basis, or to realize the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred tax liabilities or assets are expected to be settled or recovered.
Accounting for trust accounts	(z) Accounting for trust accounts The Group accounts for trust accounts separately from its group accounts under the Financial Investment Services and Capital Markets Act and thus the trust accounts are not included in the consolidated financial statements except Guaranteed Fixed Rate Money Trusts controlled by the Group, based on an evaluation of the substance of its relationship with the Group and the SPE’s risks and rewards. Funds transferred between Group account and trust accounts are recognized as borrowings from trust accounts in other liabilities with fees for managing the accounts recognized as non-interest
Earnings per share	(aa) Earnings per share The Group presents basic and diluted earnings per share (EPS) data for its ordinary shares. Basic EPS is calculated by dividing the profit or loss attributable to ordinary shareholders of the Group by the weighted average number of ordinary shares outstanding during the period, adjusted for own shares held. Diluted EPS is determined by adjusting the profit or loss attributable to ordinary shareholders and the weighted average number of ordinary shares outstanding, adjusted for own shares held, for the effects of all dilutive potential ordinary shares, which comprise convertible notes and share options granted to employees.
New standards and interpretations not yet adopted	(ab) New standards and interpretations not yet adopted The following new standards and amendments to existing standards have been published and are mandatory for the Group to adopt for annual periods beginning on or after January 1, 2018, and the Group has not early adopted them. i) IFRS 9, Financial Instruments IFRS 9, Financial Instruments Financial Instruments: recognition and measurement IFRS 9 will generally be applied retrospectively; however, the Group plans to take advantage of the exemption allowing it not to restate the comparative information for prior periods with respect to classification and measurement (including impairment) changes. For hedge accounting, the new standard will be applied prospectively except for certain cases such as accounting for the time value of options. Main characteristics of IFRS 9 are the followings; 1) classification and measurement of financial instruments based on characteristics of contractual cash flows and business model for financial instrument management, 2) impairment model based on expected credit losses, and 3) expanded scope of hedged items and hedging instruments which qualify for hedge accounting and changes in assessment method for effect of hedging relationships. For the application of IFRS 9, the Group implemented changes in its accounting processes and internal controls related to financial instruments. The Group assessed the potential financial impact of the initial adoption of IFRS 9 based on the circumstances and available information as of December 31, 2017 as follows: 1) Classification and measurement of financial assets The Group classifies financial assets as subsequently measured at amortized cost, fair value through other comprehensive income or fair value through profit or loss on the basis of both the Group’s business model for managing the financial assets and the contractual cash flow characteristics of the financial assets as shown in the below table when the new standard IFRS 9 is adopted. Furthermore, if a hybrid contract contains a host that is an asset within the scope of this standard, an embedded derivative shall not be separated from the host and the hybrid contract is accounted as a financial asset. Contractual cash flow characteristics Business model objectives Principal and interest Others Collection of the contractual cash flows Measured at amortized cost (*1)(“AC”) Fair value through profit or loss (*2) Collection of the contractual cash flows and to sale of assets Measured at fair value through other comprehensive income (*1)(“FVOCI”) sale of assets and others Measured at fair value through profit or loss (“FVPL”) (*1) The Group may irrevocably designate a financial asset as measured at fair value through profit or loss to eliminate or significantly reduce accounting mismatch. (*2) The Group may make an irrevocable election for equity instruments that are not held for trading as measured at fair value through other comprehensive income. As there are additional requirements for a financial asset to be classified as measured at amortized costs or at fair value through other comprehensive income under IFRS 9 compared to the existing IAS 39, the adoption of IFRS 9 would potentially increase the proportion of financial assets that are measured at fair value through profit or loss, increasing volatility in the Group’s profit or loss. The expected impacts on the classification and measurement of financial assets as of December 31, 2017 based on the information from the revised accounting system are as follows: Classification by Amount by IAS 39 IFRS 9 IAS 39 (*1) IFRS 9 (*1) Due from banks Loans and receivables FVPL W 902,124 833,942 AC 19,988,001 19,988,001 Loans Loans and receivables FVPL 750,342 778,985 AC 277,126,028 277,126,028 Other financial assets Loans and receivables AC 12,090,983 12,090,983 Trading assets (debt securities) Fair value through profit or loss FVPL 23,451,755 23,451,755 Trading assets (equity securities) Fair value through profit or loss FVPL 4,823,244 4,823,244 Trading assets (gold deposits) Fair value through profit or loss FVPL 189,297 189,297 Fair value through profit or loss (debt securities) Fair value through profit or loss FVPL 2,030,522 2,030,522 Designated at FVPL 80,288 80,288 Fair value through profit or loss (equity securities) Fair value through profit or loss FVPL 1,162,553 1,162,553 Designated at FVPL 71,803 71,803 Fair value through profit or loss (hybrid financial assets) Fair value through profit or loss FVPL 233,892 233,892 Available-for-sale Available-for-sale FVPL 528,745 533,452 FVOCI 36,657,807 36,657,807 Available-for-sale Available-for-sale FVPL 4,339,979 4,350,969 FVOCI 590,405 590,405 Held-to-maturity Held-to-maturity FVPL 565,813 529,906 AC 24,424,867 24,424,867 Total W 410,008,448 409,948,699 (*1) Allowance for credit losses was excluded in the carrying amount. (*2) Based on IFRS 4, the Group applies the overlay approach method for financial assets related to insurance contract (Due from banks in the amount of W Available-for-sale W Available-for-sale W Held-to-maturity W Upon adoption of IFRS 9, the Group expects to make reclassification adjustments between profit or loss and other comprehensive income on the date of initial application an amount which is equal to the difference between i) the amount reported in profit or loss for the designated financial assets applying IFRS 9; and ii) the amount that would have been reported in profit or loss for the designated financial assets if the insurer had applied IAS 39. Based on management’s evaluation to date, upon adoption of IFRS 9 as of January 1, 2018, financial assets amounting to W held-to-maturity W available-for-sale 2) Classification and measurement of financial liabilities In accordance with the new standard IFRS 9, the amount of change in the fair value of the financial liability designated as measured at fair value through profit or loss that is attributable to changes in the credit risk of that liability will be presented in other comprehensive income, not profit or loss. Amounts presented in other comprehensive income shall not be subsequently transferred to profit or loss. However, when the treatment of the effects of changes in the liability’s credit risk would create or enlarge an accounting mismatch, the related change in the fair value can be presented in profit or loss. As some portion of the changes in fair value of the financial liability that is designated at fair value through profit or loss, which was recognized as profit or loss under IAS 39, will be presented as other comprehensive income, the profit or loss related to fair value of financial liability may decrease. The Group designated liabilities amounting to W W W W 3) Impairment: Financial assets and contract assets Under the current standard IAS 39, impairment is recognized based on incurred loss model only when there is an objective evidence of impairment. However, under the new standard IFRS 9, impairment is recognized based on expected credit loss impairment model for the debt instruments, lease receivable, contract assets, loan commitments, and financial guarantee contracts measured at amortized cost or financial assets that are measured at fair value through other comprehensive income. Unlike the current standard IAS 39 which is based on incurred loss model, credit losses may be recognized earlier under IFRS 9. As shown below, this standard requires to measure the amount for loss allowance in 3 stages based on the 12-month Stages Loss allowance Stage 1 Credit risk has not increased significantly since initial recognition (*1) 12-month Stage 2 Credit risk has increased significantly since initial recognition Lifetime expected credit losses: the expected credit losses that result from all possible default events over the expected life of a financial instrument. Stage 3 Credit-impaired (*1) The Group may assume that the credit risk on a financial instrument has not increased significantly since initial recognition if the credit risk is low at the reporting date. According to IFRS 9, the Group will only recognize the cumulative changes in lifetime expected credit losses since initial recognition as a loss allowance for financial assets impaired at its initial recognition. Under IFRS 9, the Group will apply the simplified approach for which the Group will consider a debt security to have low credit risk when its credit risk rating is equivalent to the definition of ‘investment-grade’. Based on management’s evaluation to date using the information from the revised accounting system as of December 31, 2017, the expected impacts on the allowance for loan losses are as follows: Classification Under Amount Under IAS 39 IFRS 9 IAS 39 IFRS 9 Allowance for loan losses Loans and receivables Due from banks AC W 14,054 15,062 Loans AC 2,307,276 2,871,986 FVPL 3,328 — Other financial assets AC 49,679 51,818 Available-for-sale Debt securities FVOCI — 18,711 Held-to-maturity Debt securities AC — 8,824 W 2,374,337 2,966,401 Contingent liabilities Financial guarantee contract Financial guarantee W 36,506 37,288 Allowances for unused Allowances for unused 168,006 222,499 W 204,512 259,787 4) Hedge accounting New standard IFRS 9 retains the mechanics of hedge accounting (fair value hedge, cash flow hedge, and hedge of a net investment in a foreign operation) of current standard IAS 39. However, this standard mitigated IAS 39 by amending the complex and rule-based requirements related to hedge accounting under IAS 39 to principle-based requirements to align hedge accounting more closely with risk management. Furthermore, this standard expanded the eligible hedged items and the hedging instruments and eased the requirement for the hedge accounting by removing quantitative threshold (80~125%) and changing hedge effectiveness test method. When applying hedge accounting under IFRS 9, the hedge accounting can be applied to certain transactions that do not meet the requirements for hedge accounting under IAS 39 and volatility of the profit or loss can be decreased. The Group will adopt IFRS 9 hedge accounting requirements and plans to apply hedge accounting for the risk management activities if the hedge accounting requirements can be met. As December 31, 2017, no hedge accounting is applied under IFRS 9 for risk management activities for which no hedge accounting has been applied under the existing IAS 39. ii) IFRS 15, Revenue from Contracts with Customers IFRS 15, published on November 6, 2015, is a new accounting standard about revenue recognition, is effective for annual reporting periods beginning on or after January 1, 2018, with earlier application permitted. It replaces existing revenue recognition standards, including IAS 18, ‘ Revenue Construction Contracts SIC-31, Revenue-Barter Transactions Involving Advertising Services Customer Loyalty Programmes Agreements for the Construction of Real Estate Transfers of Assets from Customers The Group adopts IFRS 15 from January 1, 2018 using the cumulative effect method and the effect of initially applying this standard is recognized at the date of initial application (i.e. January 1, 2018). As a result, the Group will not apply the requirements of IFRS 15 to the comparative period presented. The existing standards suggest revenue recognition guidance by type of transactions such as sale of goods, rendering of services, interest revenue, royalty revenue, dividends revenue and construction contracts. However, according to IFRS 15, all types of contracts recognize revenue through five-step revenue recognition model (① ‘Identifying the contract’ g g g g Since the second half of 2017, the Group has formed a separate Task Force Team to prepare for the adoption of IFRS 15 and set up the relating accounting policies and processes. The Group assessed the impact of the new standard by evaluating contracts, identifying relating performance obligations, determining when the performance obligations were met to recognize revenue and assessing the revenue amount to be recognized. As a result of the assessment, there are no significant impacts from the adoption of IFRS 15 in relation to the timing of when the Group recognizes or when revenue should be recognized gross as a principal or net as an agent. iii) Amendments to IFRS 2 Classification and Measurement of Share-based Payment Transactions The amendments clarified that measuring cash-settled share-based payment should reflect the vesting conditions and non-vesting iv) IFRS 16, Leases IFRS 16, ‘ Leases Leases Determining whether an Arrangement Contains a Lease Revenue from Contracts with Customers The Group classifies whether the contract itself is a lease or the contract involves a lease at the point of lease commencement date and distinguishes whether the contract itself is a lease or the contract involves a lease based on IFRS 16. However, the Group may choose as its accounting policy not to reassess all the contracts before the date of initial application, as a practical expedient.

Goodwill	(a) Goodwill The Group assesses annually whether any objective evidence of impairment on goodwill exists in accordance with the accounting policy as described in note 3. The recoverable amount of an asset or cash-generating unit is the greater of its value in use and its fair value less costs to sell. Value in use is measured based on estimates.
Income taxes	(b) Income taxes The Group is subject to tax law from various countries. Within the normal business process, there are various types of transaction and different accounting method that may add uncertainties to the decision of the final income taxes. Deferred tax is recognized, using the asset-liability method, in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. A deferred tax liability is recognized for taxable temporary differences and a deferred tax asset is recognized for deductible temporary differences to the extent that it is probable that taxable profit will be available against which they can be utilized and the taxable profit will be created in appropriate periods. However, actual income tax in the future may not be identical to the recognized deferred tax assets and liabilities, and this difference can affect current and deferred tax at the year when the final tax effect is finalized.
Fair value of financial instruments	(c) Fair value of financial instruments The fair values of financial instruments which are not actively traded in the market are determined by using valuation techniques. The Group determines valuation method and assumptions based on significant market conditions at the end of each reporting year. Diverse valuation techniques are used to determine the fair value of financial instruments, from general market accepted valuation model internally developed valuation model that incorporates various types of assumptions and variables.
Allowances for loan losses, guarantees and unused loan commitments	(d) Allowances for loan losses, guarantees and unused loan commitments The Group determines and recognizes allowances for losses on loans through impairment testing and recognizes provision for guarantees and unused loan commitments. The accuracy of provisions of credit losses is determined by the methodology and assumptions used for estimating expected cash flows of the borrower for allowances on individual loans and collectively assessing allowances for groups of loans, guarantees and unused loan commitments.
Defined benefit obligation	(e) Defined benefit obligation The present value of defined benefit obligation that is measured by actuarial valuation method uses various assumptions which can change according to various elements. The rate used to discount post-employment benefit obligations is determined by reference to market yields at the end of the reporting year on high quality corporate bonds. The currency and term of the corporate bonds are consistent with the currency and estimated term of the post-employment benefit obligations. Actuarial gains and losses including experience adjustments and the effects of changes in actuarial assumptions are recognized in other comprehensive income or loss. Other significant assumptions related to defined benefit obligation are based on current market situation.
Impairment of available-for-sale equity investments	(f) Impairment of available-for-sale When there is a significant or prolonged decline in the fair value of an investment in an equity instrument below its original cost, there is objective evidence that available-for-sale
Hedging relationship	(g) Hedging relationship The hedging instruments are expected to be “highly effective” in offsetting the changes in the fair value or cash flows of the respective hedged items during the period. For a cash flow hedge of a forecasted transaction, the transaction should be highly probable to occur and should present an exposure to variations in cash flows that could ultimately affect reported net income.

Under the guidelines set forth by the Financial Supervisory Commission of Korea, all major commercial banks in Korea, including Shinhan Bank, follow the standardized approach under Basel III for purposes of computing Bank of International Settlement (BIS) ratios for risk classifications of loans to banks and governments. Under this standardized approach under Basel III, risk classification for loans to banks and governments are determined on the basis of sovereign credit ratings, and not internal credit ratings assigned by the lending bank that are specific to the individual banks and governments.

Sensitivity analysis for fair value measurements in Level 3	• Sensitivity analysis for fair value measurements in Level 3 Although the Group believes that its estimates of fair value are appropriate, the use of different methodologies or assumptions could lead to different measurements of fair value. For level 3 fair value measurement, changing one or more of the unobservable inputs used to reasonably possible alternative assumptions would have the following effects on profit or loss, or other comprehensive income as of December 31, 2016 and 2017. 2016 Favorable Unfavorable Financial assets: Effects on profit or loss for the period (*1): Financial assets designated at fair value through profit or loss W 2,737 (3,260 ) Derivative assets 38,746 (17,927 ) 41,483 (21,187 ) Effects on other comprehensive income for the period: Available-for-sale 59,782 (34,830 ) W 101,265 (56,017 ) Financial liabilities: Effects on profit or loss for the period (*1): Financial liabilities designated at fair value through profit or loss W 80,057 (108,955 ) Derivative liabilities 80,589 (49,740 ) W 160,646 (158,695 ) 2017 Favorable Unfavorable Financial assets: Effects on profit or loss for the period (*1): Trading assets W 2,792 (2,742 ) Financial assets designated at fair value through profit or loss 1,843 (1,941 ) Derivative assets 29,059 (28,077 ) 33,694 (32,760 ) Effects on other comprehensive income for the period: Available-for-sale 39,460 (25,505 ) W 73,154 (58,265 ) Financial liabilities: Effects on profit or loss for the period (*1): Financial liabilities designated at fair value through profit or loss W 72,063 (56,754 ) Derivative liabilities 32,770 (33,343 ) W 104,833 (90,097 ) (*1) Fair value changes are calculated by increasing or decreasing the volatility of the underlying asset (-10~10%) (-10~10%). (*2) Fair value changes are calculated by increasing or decreasing discount rate (-1~1%)
The method of measuring the fair value of financial instruments measured at amortized cost	• The method of measuring the fair value of financial instruments measured at amortized cost is as follows: Type Measurement methods of fair value Cash and due from banks The carrying amount and the fair value for cash are identical and most of deposits are floating interest rate deposits or next day deposits of a short-term instrument. For this reason, the carrying value approximates fair value. Loans The fair value of the loans is measured by discounting the expected cash flow at the market interest rate and credit risk. Held-to-maturity The fair value of held-to-maturity Deposits and borrowings The carrying amount and the fair value for demand deposits, cash management account deposits, call money as short-term instrument are identical. The fair value of others is measured by discounting the contractual cash flow at the market interest rate that takes into account the residual risk. Debt securities issued Where available, the fair value of deposits and borrowings is based on the published price quotations in an active market. In case there is no data for an active market price, it is measured by discounting the contractual cash flow at the market interest rate that takes into account the residual risk.
