In accordance with the restructuring plan by the Ministry of Knowledge Economy (the “MKE”, formerly the Ministry of Commerce, Industry and Energy) on January 21, 1999 (the “Restructuring Plan”), the Company spun off its power generation division on April 2, 2001, resulting in the establishment of six power generation subsidiaries. Also, to create internal competition among the business divisions and ultimately improve efficiency, KEPCO launched the strategic business units on September 25, 2006.

(b) Basis of Presenting Consolidated Financial Statements

KEPCO maintains its accounting records in Korean Won and prepares the consolidated financial statements in the Korean language (Hangul) in conformity with the KEPCO Act, Accounting Regulations for Public Enterprise Associate Government Agency, which have been approved by the Korean Ministry of Strategy and Finance and, in the absence of specialized accounting regulations for utility companies, the accounting principles generally accepted in the Republic of Korea (collectively “Korean GAAP”). Certain accounting principles applied by the Company that conform with financial accounting standards and accounting principles in the Republic of Korea may not conform with generally accepted accounting principles in other countries. Accordingly, these consolidated financial statements are intended solely for use by those who are informed about Korean accounting principles and practices, the KEPCO Act and Accounting Regulations for Public Enterprise·Associate Government Agency. The accompanying consolidated financial statements have been condensed, restructured and translated into English (with certain expanded descriptions) from the Korean language consolidated financial statements. Certain information included in the Korean language consolidated financial statements, but not required for a fair presentation of the Company’s financial position, results of operations, changes in shareholders’ equity or cash flows, is not presented in the accompanying consolidated financial statements.

In 2007, the Company also adopted amended SKAS No. 16—“Income Taxes” which are amended such that additional payment of income taxes and income tax refunds, formerly classified as other income (expenses), are reclassified as income taxes. Moreover, consolidated subsidiaries’ deferred income tax assets and liabilities, formerly recorded at net amount, are separately recorded in the consolidated balance sheets.

(c) Principles of Consolidation

The consolidated financial statements include the accounts of KEPCO and its controlled subsidiaries (collectively referred to as the “Company”). Controlled subsidiaries include majority-owned entities by either the Company or controlled subsidiaries and other entities where the Company or its controlled subsidiary owns more than 30% of total outstanding common stock and is the largest shareholder.

For investments in companies, whether or not publicly held, that are not controlled, but under the Company’s significant influence, the Company utilizes the equity method of accounting. Significant influence is generally deemed to exist if the Company can exercise influence over the operating and financial policies of an investee. The ability to exercise that influence may be indicated in several ways, such as the Company’s representation on its board of directors, the Company’s participation in its policy making processes, material transactions with the investee, interchange of managerial personnel, or technological dependency. Also, if the Company owns directly or indirectly 20% or more of the voting stock of an investee and the investee is not required to be consolidated, the Company generally presumes that the investee is under significant influence.

When a controlling company still has control over its subsidiaries even after the controlling company sold a portion of its investment in the subsidiaries, the disposal gain or loss realized in connection with the sale of a subsidiary’s common stock should be presented as additions or deductions of consolidated capital surplus in the consolidated financial statements.

All intercompany balances including trade receivables and trade payables are eliminated in consolidation. Profits and losses on intercompany sales of products, property or other assets are eliminated in the consolidated financial statements based on the gross profit or loss recognized. For downstream sales, the full amount of intercompany profit is eliminated in the consolidated statements of income. For upstream sales, the elimination is allocated proportionately to consolidated income and minority interests.

As result, these investments are accounted for under equity method.

(f) Elimination of Investments and Shareholder’s Equity

For consolidated subsidiaries and investments accounted for under the equity method, if the acquisition date is not as of the fiscal year end of the investee, the nearest fiscal year end of such investee is considered as the acquisition date in determining the amount of goodwill or negative goodwill.

The equity securities other than securities in Korea Power Exchange, Kanglim Co., Ltd. and Cockatoo Coal Ltd. are non-marketable securities and stated at cost due to the lack of information to determine fair value.

Investment in affiliates in which the Company owns 20% or more of the voting stock should be stated at an amount as determined using equity method of accounting. However, as allowed per SKAS No. 8 “Investments in Securities”, as the difference between the equity method and cost is considered to be immaterial, the Company recorded the investment within available-for-sale securities at cost.

Korea Power Exchange operates under the regulations for government affiliated organization, electric power market managerial regulations, and the Electricity Enterprises Act. Moreover, considering the purpose of establishment and articles of incorporation of Korea Power Exchange, the Company does not appear to have significant management control. Therefore, the investment is accounted for as available-for-sale at fair value. Based on the valuation report by the third party, the Company recorded valuation loss of KRW10,158 million for its investment in Korea Power Exchange, which have been accounted for as accumulated other comprehensive income.

The stock of Kanglim Co., Ltd. was listed on the Korea Securities Dealers Automated Quotation (the “KOSDAQ”) and those securities are evaluated at quoted market value (closing price as of the balance sheet date). The Company recorded loss on valuation of KRW105 million, which have been accounted for as accumulated other comprehensive income.

The Company invested in overseas oil development industry with a consortium of Korean companies (the “Korean Consortium”) consisting of the Company, Korea National Oil Corporation and Daewoo Shipbuilding & Marine Engineering Co., Ltd. The Korean Consortium, owning 60% equity interest in the joint venture incorporated with Equator Exploration Limited and Nigerian governments, invested in KNOC Nigerian East 323, KNOC Nigerian West 321 and Dolphin Property Ltd. Additionally, the Company provides performance guarantees of US$25 million related to the oil and gas producing activities and US$54 million related to the construction of power generation plants and gas pipes to Nigerian government.

As investments in Cockatoo Coal Ltd. is recorded at fair value as a marketable security, the Company recorded gain on valuation of KRW1,829 million as accumulated other comprehensive income.

(*1) The KEPCO Act requires the Company to appropriate a legal reserve equal to at least 20 percent of net income for each accounting period until the reserve equals 50 percent of the common stock. The legal reserve is not available for cash dividends; however, this reserve may be credited to paid-in capital or offset against accumulated deficit by the resolution of the shareholders.

(*2) The reserve for the investment on social overhead capital and the reserve for research and human development are appropriated by the Company to avail itself of qualified tax credits to reduce corporate tax liabilities. These reserves are not available for cash dividends for a certain period as defined in the Tax Incentive Control Law.

(*3) Until December 10, 2002 under the Special Tax Treatment Control Law (the “Law”), investment tax credit was allowed for certain investments. The Company was, however, required to appropriate from retained earnings the amount of tax benefits received and transfer such amount into a reserve for business rationalization. Effective December 11, 2002, the Company is no longer required to establish a reserve for business rationalization for tax benefits received for certain investments. However, existing reserves are not available for cash dividends and can be credited only to paid-in capital or offset against any accumulated deficit by resolution of the shareholders.

(*4) Prior to 1990, according to the KEPCO Act, at least 20 percent of net income in each fiscal year was required to be established as a reserve for business expansion until such reserve equals the common stock. Beginning in 1990, no reserve is required.

(*5) The reserve for dividend equalization, which is considered a voluntary reserve, is appropriated by the Company to reduce fluctuation of dividend rate for the purpose of stock price and credit rating stabilization.

	Won (millions)
	2008			2009
Estimated accrual at beginning of year	KRW	1,776,614		2,190,771
Provision for retirement and severance benefits		483,909		93,273
Payments		(78,204	)	(123,585	)

Net balance at end of year	KRW	1,735,457		1,727,002

(*) Funding of the retirement and severance benefits are not required, however, tax deductions are limited if the liability is not funded. The Company purchased individual severance insurance deposits, which meet the funding requirement for tax deduction purposes, in which the beneficiary is the respective employee, with a balance of KRW434,174 million as of June 30, 2009, and are presented as a deduction from the accrual of retirement and severance benefits.

The company transferred KRW91 million to the National Pension in accordance with the National Pension Scheme of Korea, and it is reflected in the consolidated balance sheet as a reduction of the retirement and severance benefit liability.

(20) Liability for Decommissioning Costs

Under the Korean Electricity Business Act (EBA) Article 94, the Company is required to record a liability for the dismantling of nuclear power plants and disposal of spent fuel and low & intermediate radioactive wastes. In addition, under the Korean Atomic Energy Act (AEA), an entity which constructs and operates a nuclear power reactor and related facilities must obtain permission from the Ministry of Education, Science and Technology (the “MEST”, formerly the Ministry of Science and Technology).

Effective January 1, 2004, the Company early adopted SKAS No. 17 and retrospectively adjusted the liability for decommissioning costs to the estimated fair value using discounted cash flows to settle the asset retirement obligations of dismantling and disposal of the nuclear power plants, spent fuel and low & intermediate radioactive waste.

In 2008, Radio-active Waste Management Act (“RWMA”) was enacted, which is effective as of January 1, 2009, in an effort to centralize the disposal of spent fuel and low & intermediate radioactive waste and related management process.

Even after the enactment of RWMA, the Company is still responsible for dismantling of nuclear power plants without any changes in their operation and accounting treatment, but for the disposal of spent fuel and low & intermediate radioactive waste, the responsibility was transferred to newly established Korea Radioactive Waste Management Corporation (“KRMC”), a government-owned entity.

As of December 31, 2008 and June 30, 2009, the Company has recorded a liability of KRW5,470,764 million and KRW5,609,441 million, respectively, for dismantling and decontaminating existing nuclear power plants, consisting of dismantling costs of nuclear plants of KRW4,311,052 million and KRW4,310,967 million as of December 31, 2008 and June 30, 2009 and storage costs of spent fuel and low & intermediate radioactive waste of KRW1,159,712 million and KRW1,298,474 million as of December 31, 2008 and June 30, 2009, respectively. Accretion expense consists of period-to-period changes in the liability for decommissioning costs resulting from passage of time and changes in estimate related to either the timing or the amount of the initial estimate of undiscounted cash flows. This cost is included in cost of electric power in the accompanying statements of income.

For the year ended December 31, 2006, the Company computerized the processes for recording capitalized asset retirement costs and liability for decommissioning costs in relation to dismantling the nuclear power plants and storage of spent fuel and radioactive wastes. As part of the computerization process, the Company initiated a thorough investigation to identify accurate quantities of spent fuel and radioactive waste. As a result of the investigation, the Company found discrepancies between physical counts performed and pre existing data. In addition, the Company changed the timing of asset retirement cost recognition for spent fuel from when spent fuel is released to when new nuclear fuel is loaded. As a result of the discrepancy and the change in the timing of recognition, the Company adjusted the beginning balances of asset retirement costs and liability for decommissioning costs by KRW5,255 million and recognized it as a prior year error correction in the consolidated statements of income for year ended December 31, 2006.

Changes in the liability for decommissioning costs for the year ended December 31, 2008 and for the six-month period ended June 30, 2009 are summarized as follows:

	Won (millions)
	2008			2009
Balance at beginning of year	KRW	8,206,267		5,470,764
Liabilities incurred		470,376		131,888
Accretion expense for year		379,281		95,555
Payments for year		(8791	)	(88,766	)
Transfer to long-term other accounts payable		(3,576,369	)	—
Balance at end of year	KRW	5,470,764		5,609,441

(21) Provision for Decontamination of Transformer

Under the new regulation of Persistent Organic Pollutants Management Act, enacted in 2007, the Company is required to inspect and dispose of transformers and recorded a liability for inspection and disposal cost related to decontamination of existing transformers. Expenditures on inspection and disposal of transformers are expected to occur in the following 8 years and they can vary because of changes in assumed dates of regulatory requirement, technology.

(22) Other Current Liabilities

(34) Reconciliation to United States Generally Accepted Accounting Principles

The accompanying consolidated financial statements are prepared in accordance with Korean GAAP which differs in certain respects from U.S. generally accepted accounting principles (“U.S. GAAP”). The significant differences between Korean GAAP and U.S. GAAP that affect the Company’s consolidated financial statements are described below.

(a) Revenue Recognition

The Company reads meters and bills customers on a cycle basis. The Company does not accrue revenue for power sold to customers between the meter-reading date and balance sheet date but records the revenue in the subsequent period. Under Korean GAAP, such practice is consistent with the Accounting Regulations for Public Enterprise Associated Government Agency, which have been approved by the Korean Ministry of Strategy and Finance (formerly the Korean Ministry of Finance and Economy) and considered by the utility industry in Korea as Korean GAAP. However under U.S. GAAP beginning in 2006, the Company recognizes unbilled revenue representing the sale of power between the cycle meter-reading date and the balance sheet date. Prior to 2006, the Company did not recognize any difference for amounts recognized under Korean GAAP, and had concluded that such prior year uncorrected differences were quantitatively and qualitatively immaterial to the Company’s prior year consolidated financial statements using the income statement approach.

In September 2006, the Securities and Exchange Commission (“SEC”) issued Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year Financial Statements” (“SAB 108”). SAB 108 requires the use of the “dual approach” (both an income statement approach and a balance sheet approach) when evaluating whether an error is material to an entity’s financial statements, based on all relevant quantitative and qualitative factors. The SEC issued SAB 108 to address what the SEC identified as diversity in practice whereby entities were using either an income statement approach or a balance sheet approach, but not both.

Effective December 31, 2006, the Company adopted SAB 108 and recorded the effects of prior year uncorrected differences which arose prior to January 1, 2006, as a cumulative effect adjustment to beginning retained earnings as of January 1, 2006 in accordance with the “dual approach” set forth in SAB 108.

(b) Asset Revaluation and Depreciation

Under Korean GAAP, property, plant and equipment are stated at cost, except for those assets that are stated at their appraised values in accordance with the KEPCO Act and the Assets Revaluation Law of Korea. In connection with an asset revaluation, a new basis for the property, plant and equipment is established. Asset revaluations are not permitted after January 1, 2001.

Under U.S. GAAP, property, plant and equipment must be stated at cost less accumulated depreciation and impairment. The revaluation of property, plant and equipment and the resulting depreciation of revalued amounts are not included in consolidated financial statements prepared in accordance with U.S. GAAP. When revalued assets are sold, revaluation surplus related to those assets under Korean GAAP would be reflected in income as additional gain on the sale of property, plant and equipment under U.S. GAAP.

(c) Special Depreciation

Under Korean GAAP, special depreciation allowed prior to 1944, which represents accelerated depreciation of certain facilities and equipment acquired for energy saving and anti-pollution purposes, is not recognized under U.S. GAAP. The U.S.GAAP reconciliation reflects the adjustment of special depreciation to the Company’s normal depreciation method, based on the economic useful life of the asset.

(d) Accounting for Regulation

U.S. GAAP, pursuant to Statements of Financial Accounting Standards (“SFAS”) No. 71 “Accounting for the Effects of Certain Types of Regulation” differs in certain respects from the application of U.S. GAAP by non-regulated businesses. As a result, a regulated utility is required to defer the recognition of costs (a regulatory asset) or recognize obligations (a regulatory liability) if it is probable that, through the rate-making process, there will be a corresponding increase or decrease in future utility rates.

The Government of the Republic of Korea approves the rates that the Company charges to its customers. The Company’s utility rates designed to recover its reasonable costs plus a fair investment return. However, as discussed in Note 1(a), on April 2, 2001, six power generation subsidiaries were established in accordance with the Restructuring Plan. Since the power generation subsidiaries’ rate are determined by a competitive system in the market, they no longer meet the criteria for application of SFAS No.71.Accordingly, since 2001, only the Company’s power transmission and distribution divisions have been subject to the criteria for the application of SFAS No.71.

The Company recognizes a regulatory liability or regulatory asset in consolidated financial statements by a charge or credit to operations to match revenues and expenses under the regulations for the establishment of utility rates. These assets or liabilities relate to the adjustments for capitalized foreign currency translation, reserve for self-insurance and deferred income taxes.

The following table shows the components of regulated assets and liabilities as of December 31, 2008 and June 30, 2009.

	Korean Won(in millions)						Translation into U.S. Dollar (Note 2) (in thousands)
	2008			2009			2009
Capitalized foreign currency translation	KRW	609,723		KRW	583,965		$	458,551
Reserve for self-insurance		(115,268	)		(114,681	)		(90,052	)
Deferred income taxes		(1,068,372	)		(1,045,716	)		(821,135	)
	KRW	(573,917	)	KRW	(576,432	)	$	(452,636	)

The regulated assets resulting from capitalized foreign currency translation are anticipated to be recovered over the weighted-averaged useful life of property, plant and equipment.

Regulatory assets and liabilities are established based on the current regulations and rate-making process. Accordingly, these assets and liabilities may be significantly changed due to the potential future deregulation or changes in the rate-making process.

(e) Reversal of Eliminated Profit on Transactions with Subsidiaries and Affiliated Companies

Under Korean GAAP, the Company’s share of the profit on transactions between KEPCO and its affiliated companies is eliminated in the preparation of the consolidated financial statements. No elimination of such profit is required in accordance with U.S. GAAP for regulated enterprises, where the sales prices are reasonable and it is probable that, through the rate making process, future revenues approximately equal to the sales price will result from the Company’s use of the utility plant. The Company meets both of these criteria, and no elimination of profit is necessary for reporting under U.S. GAAP.

(f) Foreign Currency Translation

As discussed in note, under Korean GAAP, the Company capitalizes certain foreign exchange transaction and translation gains and losses on borrowings associated with certain qualified assets during the construction period.

Under U.S. GAAP, all foreign exchange transaction gains and losses (referred to as either transaction or translation gains (losses) under Korean GAAP) should be included in the results of operations for the current period. Accordingly, the amounts of foreign exchange transaction and translation gains and losses included in property, plant and equipment under Korean GAAP were reversed into results of operations for the current period under U.S. GAAP.

Under Korean GAAP, convertible bonds denominated in foreign currency are regarded as non-monetary liabilities since they have equity-like characteristics. Accordingly, the Company does not recognize the associated foreign currency translation gain or loss.

Under U.S. GAAP, convertible bonds denominated in foreign currency are translated at exchange rates as of the balance sheet date, and the resulting foreign currency translation gain or loss is included in the results of operations.

(g) Intangible Assets

Under Korean GAAP, all costs incurred during the research phase are expensed as incurred. Costs incurred during the development phase are recognized as an asset only if all of the following criteria for recognition are satisfied; (1) it is probable that future economic benefits that are attributable to the asset will flow into the entity; and (2) the cost of the asset can be reliably measured. If the costs incurred fail to satisfy all of these criteria, they are recorded as periodic expense as incurred.

Under U.S. GAAP, all costs incurred during the research and development stages are expensed as incurred with the exception of certain computer software costs defined in Statement of Position (the “SOP”) 98-1. Under SOP 98-1, internal and external costs incurred to develop internal-use computer software during the application development stage should be capitalized.

(h) Deferred Income Taxes

Under Korean GAAP, prior to January 1, 2005, deferred taxes were not recognized for temporary differences related to the conversion right of the convertible bond issued, unrealized gains and losses on investment securities, equity in other comprehensive income of affiliates and unrealized gains and losses on derivatives considered to be cash flow hedges that were reported as a separate component of shareholders’ equity. Effective January 1, 2005, the Company adopted SKAS No. 16 “Income Taxes.” In accordance with this standard, deferred taxes are recognized on the temporary differences related to the conversion right of the convertible bond issued, unrealized gains and losses on investment securities, equity in other comprehensive income of affiliates and unrealized gains and losses on derivatives considered to be cash flow hedges and are reported as a separate component of shareholders’ equity.

Under U.S. GAAP, deferred taxes are recognized on the temporary differences related to unrealized holding gains and losses on available-for-sale securities and unrealized gains and losses on derivatives considered to be cash flow hedges and are included in equity as a component of accumulated other comprehensive income, net of applicable taxes.

Changes in corporate tax rates for fiscal year 2009 and 2010 thereafter in Korea were enacted from 27.5% into 24.2% and 22%, respectively. According to FAS 109 paragraph 27, “Deferred tax liabilities and assets shall be adjusted for the effect of a change in tax laws or rates. The effect shall be included in income from continuing operations for the period that includes the enactment date.” In compliance with FAS 109, the effect of changes in tax rates was calculated of which amounts KRW42,314 million and accounted for tax expense (income from continuing operation).

(i) Accounting for Uncertainty in Income Taxes

In July 2006, the FASB issued FASB Interpretation No. 48 (“FIN48”) - “Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109,” which set outs a consistent framework to use to determine the appropriate level of tax reserve for uncertain tax positions. This interpretation uses two-step approach wherein a tax benefit is recognized if a position is more-likely-than-not to be sustained. The amount of the benefit is then measured to be the highest tax benefit which is greater than 50% likely to be realized. The difference between the benefit recognized for a position in accordance with this FIN 48 and the tax benefit claimed on a tax return is referred to as an unrecognized tax benefit.

The Company adopted FIN 48 effective January 1, 2007, and elected to classify interest and penalties related to tax positions as a component of income tax expense.

The beginning balances of unrecognized tax benefits reconcile to the balance as of December 31, 2008 and June 30, 2009 in the following table:

	Korean Won(in millions)				Translation into U.S. Dollar (Note) (in thousands)
	2008			2009	2009
Total unrecognized tax benefits at January 1	KRW	5,690		12,695	$	9,969
Amount of increase for current year’s tax position		11,394		46		36
Gross amount of increases for prior years’ tax position		458		0		0
Gross amount of decreases for prior years’ tax position		(4,847	)	0		0
Total unrecognized tax benefit at December 31 (or June 30 for 2009)	KRW	12,695		12,741	$	10,005

Any changes in the amounts of unrecognized tax benefits related to temporary differences would result in a reclassification to deferred tax liability, and any changes in the amounts of unrecognized tax benefits related to permanent differences would result in an adjustment to income tax expense and therefore, the Company’s effective tax rate. As of December 31, 2008 and June 30, 2009, the unrecognized tax benefits included above which would, if recognized, affect the effective tax rate is KRW6,438 million and KRW6,461 million, respectively.

The Company’s continuing practice is to recognize interest and penalties, if any, related to income tax matters in income tax expense. After the adoption of FIN 48, the Company has total gross accrual for interest income and penalties of KRW3,537 million and KRW3,741 million as of December 31, 2008 and June 30, 2009.

The Company’s major tax jurisdiction is the Republic of Korea, and during the periods ended December 31, 2008 and June 30, 2009, tax examinations for six entities, including KEPCO, were carried out. The Unrecognized tax benefits as of June 30, 2009 reflects tax examination results.

(j) Liabilities for Decommissioning Costs

Prior to 2003

Under Korean GAAP, prior to January 1, 2003, the Company accrued for estimated decommissioning costs of nuclear facilities based on engineering studies and the expected decommissioning dates of the nuclear power plant. Annual additions to the reserve were in amounts such that the expected costs would be fully accrued for at the estimated dates of decommissioning on a straight-line basis.

Under U.S. GAAP, prior to January 1, 2003, accounting for liabilities for decommissioning costs was substantially the same as Korean GAAP.

2003

Under Korean GAAP, effective January 1, 2003, the Company adopted Korea Accounting Standard Board issued Statement of Korea Accounting Standards (“SKAS”) No. 5 “Tangible Assets.” Under this standard, the Company would record the fair value of the liabilities for the decommissioning costs as a liability in the period in which the Company incurs a legal obligation associated with the retirement of tangible long-lived assets. However, this standard was only applicable to new plants (with an associated asset retirement liability) put into service after January 1, 2003. For plant’s put into service before January 1, 2003, SKAS No. 5 did not apply and the previous Korean GAAP (as described above) was required. Since the Company did not place into service any assets with liabilities for decommissioning costs during 2003, SKAS No. 5 had no impact on the 2003 consolidated financial statements.

Under U.S. GAAP, effective January 1, 2003, the Company adopted SFAS No. 143 “Accounting for Asset Retirement Costs” Under SFAS No. 143, the Company is required to recognize an estimated liability for legal obligations associated with the retirement of tangible long-lived assets. The Company measures the liability at fair value when incurred and capitalizes a corresponding amount as part of the book value of the related long-lived assets. The increase in the capitalized cost is included in determining depreciation expense over the estimated useful life of these assets. Since the fair value of the liabilities for decommissioning costs is determined using a present value approach, accretion of the liability due to the passage of time is recognized each period as expense until the settlement of the liability.

SFAS No. 143 applies to all existing long-lived assets including those acquired before January 1, 2003. As a result of the adoption of SFAS No. 143, the Company recognized a pre-tax gain as a cumulative effect of accounting change of KRW1,775,306 million on January 1, 2003. In addition, for the year ended December 31, 2003, the Company recorded accretion expense and depreciation expense under U.S. GAAP while reversing the provision for decommissioning costs recorded under Korean GAAP.

2004 and thereafter

In October 2004, KASB issued Statement of SKAS No. 17 “Provisions and Contingent Liability & Asset”. In January 2005, the Company decided to early adopt SKAS No. 17. Under this standard, the Company retrospectively adjusted the liability for decommissioning costs at the estimated fair value using discounted cash flows (also based on engineering studies and the expected decommissioning dates) to settle the liabilities for decommissioning costs and the same amount was recognized as an utility asset. Under SKAS No. 17, the discount rate was set at the date of adoption and should be applied in all future periods. In addition, any new plants would use the discount rate in effect at the time of its commencement. Accretion expense consists of period-to-period changes in the liability for decommissioning costs resulting from the passage of time and revisions to either

the timing or the amount of the original estimate of undiscounted cash flows. In addition, as required by SKAS No. 17, the cumulative effect of a change in accounting included any changes in estimate that took place during 2004. Due to the adoption of this standard, the Company re-measured the liability for decommissioning costs as of January 1, 2004 and reflected the cumulative effect of a change in accounting up to prior year into current year retained earnings.

Under U.S. GAAP, the Company continues to apply SFAS No. 143 in 2004 and thereafter.

Since the adoption of SKAS No. 17 and up to date, Korean GAAP and U.S. GAAP for recording the liabilities for decommissioning costs are substantially the same except for the following:

• Under U.S. GAAP, the discount rate for existing decommissioning liabilities was set when the Company adopted SFAS No. 143 (6.49% as of January 1, 2003). Under Korean GAAP, the discount rate for existing decommissioning liabilities was set when the Company adopted SKAS No. 17 (4.36% as of December 2004).

• Under U.S. GAAP, any changes that result in upward revisions to the undiscounted estimated cash flows shall be treated as a new liability and discounted at the then current discount rate. Any downward revisions to the undiscounted estimated cash flows will result in a reduction of the liability for decommissioning costs and shall be reduced from the recorded discounted liability at the rate that was used at the time the obligation was originally recorded. Under Korean GAAP, regardless of upward or downward revisions to the undiscounted estimated cash flows, the historical discount rate will be applied in all future periods.

In 2008, as the regulation that defines responsibility of decommission were changed from the Electricity Enterprise Act to Radioactive Waste Management Act, Korea Radioactive Management Corporation (KRMC) was established. This made the responsibility to decommissioning the used nuclear fuel and low-level waste transferred from the Company to KRMC and the Company no more needs to account for the related liabilities and assets. Radioactive Waste Management Act does not result in the difference between K-GAAP and US-GAAP when treating the liabilities for decommissioning costs of the used nuclear fuel and low-level as of December 31, 2009

As explained in note, under Korean GAAP, the Company has accrued (Won) 5,584,458 million for the cost of dismantling and decontaminating existing nuclear power plants as of June 30, 2009. Under U.S. GAAP, the Company has accrued KRW4,175,633 million for the cost of dismantling and decontaminating existing nuclear power plants as of June 30, 2009. Substantially all of the difference between the U.S. GAAP liability and the Korean GAAP liability is due to the impact of the discount rate described in the first bullet above.

Amounts reconciled from Korean GAAP to U.S. GAAP for capitalized asset retirement costs, net of accumulated depreciation and liabilities for decommission costs are as follows:

	Korean Won(in millions)					Translation into U.S. Dollar (Note 2) (in thousands)
	2008			2009		2009
Decrease in capitalized asset retirement costs, net of accumulated depreciation	KRW	(866,658	)	(846,419	)	$	(664,640	)
Decrease in liabilities for decommissioning Costs		1,397,480		1,408,825			1,106,262
	KRW	530,822		562,406		$	441,622

Details of the Company’s asset retirement costs as of December 31, 2008 and June 30, 2009 under U.S. GAAP are as follows:

	Korean Won(in millions)					Translation into U.S. Dollar (Note 2) (in thousands)
	2008			2009		2009
Capitalized asset retirement costs	KRW	1,134,699		1,219,350		$	957,479
Less : accumulated depreciation		(395,025	)	(492,961	)		(387,091	)
	KRW	739,674		726,389		$	570,388

Changes in liabilities for decommissioning costs as of December 31, 2008 and June 30, 2009 under U.S. GAAP is as follows:

	Korean Won(in millions)					Translation into U.S. Dollar (Note 2) (in thousands)
	2008			2009		2009
Balance at beginning of year	KRW	5,911,298		4,061,056		$	3,198,495
Liabilities incurred		470,376		131,888			103,563
Accretion expense for the year		320,250		84,210			66,125
Liabilities reversed (*1)		—		—			—
Payments		(8,791	)	(88,766	)		(69,703	)

Others		956,520		—			—
Balance at end of year	KRW	4,073,284		4,188,388		$	3,298,480

(*1) In 2007, the usage period of Kori-1 nuclear generation unit was extended by 10 years under the permission of MESK. Accordingly, the Company recorded the difference between previously estimated and newly estimated amounts for the decrease in the liability.

(k) Convertible Bonds

Under Korean GAAP, the value of conversion rights is recognized as capital surplus. Also, the convertible bonds are not subject to foreign currency translation as convertible bonds are regarded as non-monetary foreign currency liabilities.

Under U.S. GAAP, per SFAS No. 133, unless a conversion right would be considered an embedded derivative instrument requiring bifurcation, no portion of the proceeds from the issuance of the convertible debt securities shall be attributed to the conversion feature. The Company has determined that the conversion feature embedded in our convertible debt should not be bifurcated. Also, the convertible bonds are subject to foreign currency translation because these convertible bonds were regarded as monetary foreign currency liabilities.

(l) Principles of Consolidation

Under Korean GAAP, minority interests in consolidated subsidiaries are presented as a component of shareholders’ equity in the consolidated balance sheet.

Under U.S. GAAP, minority interests are presented outside of the shareholders’ equity section in the consolidated balance sheet.

(m) Reserve for Self-insurance

Under Korean GAAP, in accordance with Accounting Regulations for Public Enterprise Associate Government Agency, the Company provides a self-insurance reserve for loss from accident and liability

to third parties that may arise in connection with the Company’s non-insured facilities. The self-insurance reserve is recorded until the amount meets a certain percentage of non-insured buildings and machinery.

U.S. GAAP considers loss from accidents and liability to third parties to be a contingency that is only provided for when a liability has been incurred. Contingent losses for self-insurance are generally recognized as a liability (undiscounted) when probable and reasonably estimable.

(n) Gain or loss on disposal of subsidiaries

Under Korean GAAP, when the parent company disposes of a portion of its investment in a subsidiary but still retains a controlling interest, any gain or loss on disposal should be recognized in capital surplus.

Under US GAAP, such gain or loss on disposal is recognized in other income.

(o) Gain on Valuation of Non-marketable Securities

Under Korean GAAP, non-marketable securities should be classified as available-for-sale and carried at cost or fair value if applicable, with unrealized holding gains and losses reported as other comprehensive income until realized.

However, under U.S. GAAP, investments in non-marketable equity securities that do not have readily determinable fair value are stated at cost using the cost method. As a result of the reconciliation of difference, the shareholders’ equity as of December 31, 2008 increased by KRW10,157 million compared to that under Korean GAAP.

(p) Fair Value Hierarchy

Effective January 1, 2008, the Company adopted SFAS No. 157 “Fair Value Measurements”. In accordance with the provisions of FSP No. FAS 157-2, the Company has decided to defer the adoption of SFAS No. 157 a year for nonfinancial assets and nonfinancial liabilities that are recognized or disclosed at fair value in the financial statements on a nonrecurring basis.

SFAS No. 157 provides for the following:

(i) Defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, and establishes a framework for measuring fair value;

(ii) Establishes a three-level hierarchy for fair value measurements based upon the observable inputs to the valuation of an asset or liability at the measurement date;

(iii) Requires consideration of nonperformance risk when valuing liabilities; and

(iv) Expands disclosures about instruments measured at fair value.

The Company classifies fair value balances based on the fair value hierarchy defined by SFAS No. 157. The classification of valuation hierarchy for fair value measurements is based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy:

Level 1—Quoted prices for identical instruments in active markets;

Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose significant inputs are observable: and

Level 3—Instruments whose significant inputs are unobservable.

Following is a description of the valuation methodologies the Company used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy.

Investment securities

The Company classified available-for-sale equity securities with marketability within Level 1 of the valuation hierarchy where quoted prices are available in an active market. The Company generally

classifies its securities within Level 2 of the valuation hierarchy where quoted prices for identical instruments in active markets are not available, the Company determines the fair values of its securities using pricing models, quoted prices of securities with similar characteristics or discounted cash flow models. These models are primarily industry-standard models that consider various assumptions, including time value and yield curve as well as other relevant economic measures.

Derivatives

Derivatives are composed of cross currency swap and interest rate swaps valued using internal models that use readily observable market inputs, such as foreign currency exchange rates and swap rates. The Company classified derivatives as Level 2 within the valuation hierarchy.

Under Korean GAAP, fair value of derivatives is determined assuming the same nonperformance risk for the entity and the counterparty. However, U.S. GAAP requires consideration of both the entity’s nonperformance risk and counterparty nonperformance risk in determining the fair value of a derivative instrument. Due to such differences, for U.S. GAAP purpose, net income and other comprehensive income for the year ended June 30, 2009 were increased by KRW17,574 compared to those under Korean GAAP.

The following table presents assets and liabilities measured and recorded at fair value on a recurring basis as of June 30, 2009:

(in millions of Korean won)	Level 1		Level 2		Level 3		Total
Assets:
Investment securities	KRW	36,857	KRW	488,472	KRW	—	KRW	525,329

(q) Fair Value of Financial Instruments

The following methods and assumptions were used to estimate the fair value of each class of significant financial instruments in which it is practicable to estimate that value:

(i) Cash and cash equivalents, short term financial instruments, trade receivables, short-term borrowings, and trade payables: The carrying amount approximates fair value because of its nature or relatively short maturity.

(ii) Investments: The fair value of investments with marketability is estimated based on quoted market prices for those or similar investments. For other investments for which there are no quoted market prices, it was not practicable to estimate the fair value of investments in unlisted companies.

(iii) Long-term debt: The fair value of long-term debt is estimated based on the quoted market prices for the same or similar issues, or on the current rates offered for debt of the same remaining maturities.

The carrying amounts and estimated fair values of the Company’s consolidated financial instruments as of December 31, 2008 and June 30, 2009 are summarized as follows :

	Korea Won (in millions)
	2008						2009

(s) Recent Changes in U.S. GAAP

In September 2006, the FASB issued statement No. 157, “Fair Value Measurements” (SFAS 157). SFAS 157 defines fair value, establishes a framework for measuring fair value in accordance with accounting principles generally accepted in the United States, and expands disclosures about fair value measurements. Specifically, SFAS No. 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date; establishes a three-level hierarchy for fair value measurements based on the assumptions that market participants would use in pricing the asset or liability; requires consideration of the risk in a particular valuation technique and the risk inherent in the inputs, and nonperformance risk when valuing liabilities; and expands disclosures about the inputs used to measure fair value, recurring fair value measurements using significant unobservable inputs and the effect of the measurements on earnings for the period.

Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. This hierarchy requires the Company to use observable market data and to minimize the use of unobservable inputs when determining fair value. SFAS 157 is effective for fiscal years beginning after November 15, 2007, with earlier application encouraged. SFAS 157 is required to be applied prospectively, except for certain financial instruments. Any amounts recognized upon adoption as a cumulative effect adjustment will be recorded to the opening balance of retained earnings in the year of adoption. The impact of adoption of SFAS 157 is disclosed in Note 34(p).

In February 2008, the FASB issued Staff Position No. 157-1, “Application of FASB Statement No. 157 to FASB Statement No. 13 and Other Accounting Pronouncements That Address Fair Value Measurements for Purpose of Lease Classification or Measurement Under Statement 13” (“FSP 157-1”) in order to amend SFAS No. 157 to exclude FASB Statement No. 13, “Accounting for Leases” (“SFAS No. 13”) and other accounting pronouncements that address fair value measurements for purposes of lease classification or measurement under SFAS No. 13. In addition, in February 2008, the FASB issued Staff Position No. 157-2, “Effective Date of FASB Statement No. 157” (“FSP 157-2”), which defers the effective date of SFAS 157 to fiscal years beginning after November 15, 2008 for non-financial assets and non-financial liabilities, except for those that are recognized or disclosed at fair value in an entity’s financial statements on a recurring basis (at least annually). In October 2008, the FASB issued Staff Position No. 157-3, “Determining the Fair Value of a Financial Asset When the Market for That Asset Is Not Active” (“FAS 157-3”), which further clarifies the application of SFAS No. 157 in an inactive market and provides an example to illustrate key considerations in determining the fair value of a financial asset in an inactive market. FAS 157-3 was effective immediately upon issuance.

Effective January 1, 2008, the Company adopted SFAS No. 157, FSP 157-1, FSP 157-2 and FSP 157-3 for all financial instruments and non-financial instruments accounted for at fair value on a recurring basis. Adoption of SFAS 157 did not have a material effect on our financial position or results of operations.

In February 2007, the Financial Accounting Standards Board (“FASB”) issued Statements of Financial Accounting Standards (“SFAS”) No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities,” SFAS No. 159 provides an option to elect fair value as an alternative measurement for selected financial assets, financial liabilities, unrecognized firm commitments and written loan commitments not previously recorded at fair value. Accordingly, SAFS No. 159 provides an opportunity to reduce both complexity in accounting for financial instruments and the volatility in earnings caused by measuring related assets and liabilities differently. This Statement is effective for fiscal years beginning after November 15, 2007. Effective January 1, 2008, the adoption of SFAS No. 159 did not have a material impact on its results from operations or financial position.

In December 2007, the FASB issued SFAS No. 141R, “Business Combinations” (SFAS 141R). SFAS 141R establishes principles and requirements for how an acquirer in a business combination recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed and any noncontrolling interest; recognizes and measures the goodwill acquired in the business combination or a gain from a bargain purchase; and determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination. SFAS 141R is to be applied prospectively to business combinations for which the acquisition date is on or after the beginning of an entity’s fiscal year that begins on or after December 15, 2008. The Company is evaluating the impact of SFAS 141R on our consolidated financial statements for any potential business combinations subsequent to January 1, 2009.

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements, an Amendment of ARB No. 51” (SFAS 160). SFAS 160 requires the ownership interest in subsidiaries held by parties other than the parent be clearly identified and presented in the consolidated balance sheets within equity, but separate from the parent’s equity; the amount of consolidated net income attributable to the parent and the noncontrolling interest be clearly identified and presented on the face of the consolidated statement of earnings; and changes in a parent’s ownership interest while the parent retains its controlling financial interest in its subsidiary be accounted for consistently. This statement is effective for fiscal years beginning on or after December 15, 2008. The Company is currently evaluating the impact that the adoption may have on our consolidated financial statements.

In March 2008, the FASB issued SFAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities—an amendment of FASB Statement No. 133” (SFAS 161). SFAS 161 requires increased qualitative, quantitative, and credit-risk disclosures. Required qualitative disclosures include: (1) How and why an entity is using a derivative instrument or hedging activity (e.g., for risk management or other purposes). (2) How the entity is accounting for its derivative instrument and hedged items under Statement 133 (and related guidance). (3) How the instrument affects the entity’s financial position, financial performance, and cash flows. This statement is effective for fiscal years beginning on or after November 15, 2008. The Company is currently evaluating the impact that the adoption may have on our consolidated financial statements.

In May 2008, the FASB issued SFAS No. 162, “The Hierarchy of Generally Accepted Accounting Principles” (SFAS 162). SFAS 162 is intended to improve financial reporting by identifying a consistent framework, or hierarchy, for selecting accounting principles to be used in preparing financial statements that are presented in conformity with U.S. generally accepted accounting principles (GAAP) for nongovernmental entities. SFAS 162 addresses to establish that the GAAP hierarchy should be directed to entities because it is the entity (not its auditor) that is responsible for selecting accounting principles for financial statements that are presented in conformity with GAAP. Statement 162 is effective 60 days following the SEC’s approval of the Public Company Accounting Oversight Board Auditing amendments to AU Section 411, The Meaning of Present Fairly in Conformity with Generally Accepted Accounting Principles. The Company is currently evaluating the impact that the adoption may have on our consolidated financial statements.

In May 2008, the FASB issued FASB Staff Position (FSP) APB14-1. “Accounting for Convertible Debt Instruments That May be Settled in Cash upon Conversion (Including Partial Cash Settlement)”. This Statement clarifies that convertible debt instruments that may be settled in cash upon conversion (including partial cash settlement), not addressed by Paragraph 12 of APB Opinion No. 14, “Accounting for Convertible Debt and Debt Issued with Stock Purchase Warrants”. Additionally, this

FSP specifies that issuers of such instruments should separately account for the liability and equity components in a manner that will reflect the entity’s nonconvertible debt borrowing rate when interest cost is recognized in subsequent periods. This FSP is effective for financial statements issued for fiscal years beginning after December 15, 2008. The Company is currently evaluating the impact that the adoption may have on our consolidated financial statements.

In June 2008, the FASB ratified the consensus reached by the EITF on Issue 07-5, “Determining Whether an Instrument (or Embedded Feature) Is Indexed to an Entity’s Own Stock” (Issue 07-5). Under Issue 07-5, an instrument (or embedded feature) would not be considered indexed to an entity’s own stock if its settlement amount is affected by variables other than those used to determine the fair value of a “plain vanilla” option or forward contract on equity shares, or if the instrument contains a feature (such as a leverage factor) that increases exposure to those variables. An equity-linked financial instrument (or embedded feature) would not be considered indexed to the entity’s own stock if the strike price is denominated in a currency other than the issuer’s functional currency. Issue 07-5 is effective for the Company on January 1, 2009, and the Company is currently evaluating the impact of adopting Issue 07-5 on the Company’s consolidated financial condition, operating results and cash flows.

In December 2008, the FASB issued FSP No. FAS 140-4 and FIN 46R-8, Disclosures by Public Entities (Enterprises) About Transfers of Financial Assets and Interests in Variable Interest Entities (“FSP No. FAS 140-4 and FIN 46R-8”). FSP No. FAS 140-4 and FIN 46R-8 amends the disclosure requirements of SFAS No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities, and FIN 46R and is effective for the first reporting period ending after December 15, 2008, or December 31, 2008 for the Company. The adoption of FSP No. FAS 140-4 and FIN 46R-8 did not have a material impact on its results from operations or financial condition.

In January 2009, the FASB issued FSP No. EITF 99-20-1, Amendments to the Impairment Guidance of EITF Issue No. 99-20 (“FSP No. EITF 99-20-1”). FSP No. EITF 99-20-1 amends the impairment guidance in EITF No. 99-20 to align impairment guidance in EITF 99-20 with that in SFAS No. 115 and related impairment guidance. FSP No. EITF 99-20-1 applies to beneficial interests within the scope of EITF 99-20 and is effective for periods ending after December 15, 2008, or December 31, 2008 for the Company. The adoption of FSP No. EITF 99-20-1 did not have a material impact on its results from operations or financial condition.

In April 2009, the FASB issued FSP No. FAS 115-2 and FAS 124-2. FSP No. FAS 115-2 and FAS 124-2 amends the other-than-temporary impairment guidance in GAAP for debt securities and the presentation and disclosure requirements of other-than-temporary impairments on debt and equity securities in the financial statements. This FSP does not amend existing recognition and measurement guidance related to other-than temporary impairments of equity securities. FSP No. FAS 115-2 and FAS 124-2 are effective for interim reporting periods ending after June 15, 2009, or June 30, 2009 for the Company, with early adoption permitted. The Company did not early adopt this FSP. The Company is currently evaluating the impact of the adoption of FSP No. FAS 115-2 and FAS 124-2 to its financial condition, results of operations and cash flows.

In May 2009, the FASB issued SFAS No. 165, “Subsequent Events” (SFAS 165). SFAS No. 165 establishes standards of accounting for and disclosure of events that occur after the balance sheet date but before the date that the financial statements are issued or are available to be issued. Specifically, the Statement sets forth (1) the period after the balance sheet date during which management of a reporting entity will evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements, (2) the circumstances under which an entity will recognize events or transactions occurring after the balance sheet date in its financial statements and (3) the disclosures that an entity will make about events or transactions that occurred after the balance sheet date. This Statement is effective for interim and annual periods ending after June 15, 2009. The Company is currently evaluating the impact that the adoption may have on our consolidated financial statements.

(t) Impact on Reconciliation of Adoption of Statement of Korean Accounting Standards

Effective January 1, 2007, the Company adopted the SKAS No. 21 “Preparation and Presentation of Financial Statements”, SKAS No. 23 “Earning per Share”, SKAS No.25 “Consolidation Financial Statement” and amended SKAS No.16 “Income Taxes”. The impact of those statements on the reconciliation to U.S. GAAP in 2007 was immaterial.

(u) Effect on Net Income and Shareholders’ Equity

Basic earning per share (EPS) excludes dilution and is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. Earnings per share for as of December 31, 2008 and June 30, 2009 under U.S. GAAP are as follows:
