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 for use by those who are informed about Korean accounting principles and practices. The accompanying consolidated financial statements have been condensed, restructured and translated into English with certain expanded descriptions from the Korean language financial statements. Certain information included in the Korean language financial statements, but not required for a fair presentation of the Company’s financial position, results of operations, change in stockholders’ equity or cash flows, is not presented in the accompanying consolidated financial statements.

(1) Adoption of Statements of Korea Accounting Standards (“SKAS”)

In 2009, Korea Accounting Institute (“KAI”) and the Financial Supervisory Service issued or revised various Korea accounting standards, none of which were newly adopted by the Company for the year ended December 31, 2010.

(2) Significant Accounting Policies for the Company’s Financial Statements

a. Cash and Cash Equivalents

Cash and cash equivalents include cash, substitute securities including checks issued by others, and checking accounts, ordinary deposits and financial instruments, which can be easily converted into cash and whose value changes due to changes in interest rates are not material, with maturities (or date of redemption) of three months or less from acquisition.

b. Allowance for Doubtful Accounts

The Company provides an allowance for doubtful accounts to cover estimated losses on receivables (account receivable - trade, loans, account receivable - other and other), based on collection experience and analysis of the collectability of individual outstanding receivables.

c. Inventories

The Company maintains perpetual inventory, which is adjusted to physical inventory count performed at year end. Inventories are stated at the lower of cost or market, with cost being determined as follows:

Description Method

Merchandises and finished goods Weighted-average method Work in process “ Raw materials “ Supplies “ Materials in -transit Specific Identification method Completed construction “ Uncompleted construction “ Others Weighted-average method or specific identification method

The costs of merchandise of the Glonet business unit of the Parent, raw materials and supplies of Doosan Heavy Industries & Construction Co., Ltd. and certain supplies and raw materials of Doosan Infracore Co., Ltd. and its subsidiaries are determined using the moving-average method. Doosan Electro-Materials Singapore Pte Ltd., Doosan Construction & Engineering Co., Ltd., Doosan Heavy Industries Vietnam Haiphong Co., Ltd. determine their cost of inventories using the first-in, first-out method (FIFO). The costs of finished goods and work-in-process of Doosan Heavy Industries & Construction Co., Ltd., work-in- process and raw materials of Doosan Engine Co., Ltd. and finished goods of Hanjung Power Co., Ltd. are determined using the specific identification method. When the market value of inventories (net realizable value for merchandises, finished goods, work-in-process and current replacement cost for raw materials) is less than the carrying value, the carrying value is stated at the lower of cost or market. The lower of cost or market method is applied by group of inventories and loss on inventory valuation is presented as a deduction from inventories and charged to cost of sales. As a result of such inventory valuation, the Company recognized loss on inventory valuation nil and ₩19,329 million for the years ended December 31, 2010 and 2009, respectively. However, when the circumstances which caused the valuation loss cease to exist, the valuation loss is reversed up to the original carrying amount before valuation loss. The said reversal is deducted from cost of sales. Reversal of loss on inventory valuation is ₩14,599 million and nil for the years ended December 31, 2010 and 2009, respectively. d. Securities (Excluding Equity Method Investment Securities)

Debt and equity securities are initially stated at the market value of consideration given for acquisition (market value of securities acquired if market value of consideration given is not available) plus incidental costs attributable to the acquisition of the securities and are classified into trading, available-for-sale and held-to-maturity securities depending on the purpose and nature of acquisition. In order to calculate realized gain (loss), securities are stated at cost which is determined by using the specific identification method for debt securities and the moving average method for equity securities.

- Trading securities

Securities that are bought and held principally for the purpose of selling them in the near term with active and frequent buying and selling, including securities which consist of a portfolio of securities with the clear objective of generating profits on short-term differences in price, are classified as trading securities. Trading securities are recorded at their fair value and unrealized gains or losses from trading securities are recorded as gain (loss) on valuation of trading securities included in the non-operating income (expense).

- Held-to-maturity securities

Debt securities that have fixed or determinable payments with a fixed maturity are classified as held-to- maturity securities only if the Company has both the positive intent and ability to hold those securities to maturity. However, debt securities, whose maturity dates are due within one year from the end of the reporting period, are classified as current assets.

After initial recognition, held-to-maturity securities are stated at amortized cost in the statements of financial position. When held-to-maturity securities are measured at amortized costs, the difference between their acquisition cost and face value is amortized using the effective interest rate method and the amortization is included in the cost and interest income.

- Available-for-sale securities

Debt and equity securities that do not fall under the classifications of trading or held-to-maturity securities are categorized and presented as available-for-sale securities included in investment assets. However, if an available-for-sale security matures or it is certain that such security will be disposed of within one year from the end of the reporting period, it is classified as a current asset.

Available-for-sale securities are recorded at fair value. Unrealized gain or loss from available-for-sale securities are presented as gain or loss on valuation of available-for-sale securities included in accumulated other comprehensive income (loss) of stockholders’ equity. In addition, accumulated gain or loss on valuation of available-for-sale securities are reflected in either gain or loss on disposal of available- for-sale securities or loss on impairment of available-for-sale securities upon disposal or recognition of impairment of the securities. However, available-for-sale equity securities that are not marketable and whose fair value cannot be reliably measured are recorded at acquisition cost.

When there is objective evidence that the available-for-sale securities are impaired and the recoverable amount is lower than the cost (amortized cost for debt securities) of the available-for-sale securities, an impairment loss is recognized as loss on impairment of available-for-sale securities in non-operating expense and the related unrealized gain or loss remaining in stockholders’ equity is adjusted to the impairment loss. If the value of impaired securities subsequently recovers and the recovery can be objectively related to an event occurring after the impairment loss was recognized, the reversal of impairment loss can be recognized up to the previously recorded impairment loss as a reversal of loss on impairment of available-for-sale securities in non-operating income. However, if the fair value increases after the impairment loss is recognized but does not relate to the recovery of impairment loss as described above, the increase in fair value is recorded in stockholders’ equity. The Company recorded loss on impairment of long-term investment securities totaling nil and ₩1,798 million and recovery of loss on impairment of those totaling ₩49 million and ₩8,808 million for the years ended December 31, 2010 and 2009, respectively.

e. Equity Method Investment Securities

Investments in equity securities of companies, over which the Company exercises significant influence, are reported using the equity method of accounting.

- Accounting for changes in the equity of the investee

Under the equity method of accounting, the Company records changes in its proportionate equity of the net assets of the investee depending on the nature of the underlying changes in the investee as follows: (i) “equity in income (loss) of associates” in the non-operating income (expense) for net income (loss) of the investee; (ii) “increase (decrease) in retained earnings of associates” in the retained earnings for changes in beginning retained earnings of the investee; and (iii) “increase (decrease) in equity of associates” in accumulated other comprehensive income (loss) for other changes in stockholders’ equity of the investee.

When the equity method investee’s unappropriated retained earnings carried over from prior period changes due to significant error corrections, the Company records the changes in equity as “equity in income (loss) of associates” included in the non-operating income (expense) if the impact of the changes on the Company’s consolidated financial statements is not significant. If the changes results from the changes in accounting policies of the equity method investee, they are reflected in unappropriated retained earnings carried over from prior period in accordance with SKAS on changes in accounting policy and errors corrections. When the investee declares cash dividends, the dividends to be received are deducted directly from equity method investment securities.

- Treatment of investment difference

Difference between the acquisition cost and the Company’s proportionate equity in the fair value of net assets of the investee upon acquisition (“Investment difference”) are considered (negative) goodwill and accounted for in accordance with the accounting standards for business combination. The goodwill portion is amortized over useful lives (5 years) on a straight line method while the negative goodwill portion is amortized over the weighted average useful lives of depreciable non-monetary assets of the investee. The amortization is included in “equity income (loss) of associates”. When the Company’s equity interest in the investee increases due to an increase (or decrease) in contributed capital with (or without) consideration, the changes in the Company’s proportionate equity in the investee is accounted for as investment difference. If the Company’s equity interest decreases, the changes are accounted for as “gain (loss) on disposal of the equity method investment securities”. However, if the investee is the Company’s subsidiary, those changes are accounted for as capital surplus (capital adjustments).

- Difference between the fair value and book value of net assets of the investee

Upon acquisition of the equity method investment securities, the Company’s proportionate shares in the differences between the fair values and book values of the identifiable assets and liabilities of the investee are amortized/reversed and included in “equity in income (loss) of associates” in accordance with the investee’s methods of accounting for the assets and liabilities.

- Elimination of unrealized gain or loss from intercompany transactions

The Company’s proportionate share in the gain (loss) arising from transactions between the Company and the investee, which remains in the book value of assets held as of the end of the reporting period is considered unrealized gain (loss) and adjusted to equity method investment securities. If the investee is a subsidiary of the Company, unrealized gain (loss) from sale of an asset by the Company to the investee (downstream transaction) is fully eliminated and adjusted to equity method investment securities.

- Impairment loss on equity method investment securities

When there is objective evidence that the equity method investment securities is impaired and the recoverable amount is lower than the carrying amount of the equity method investment securities, an impairment loss is recognized as “loss on impairment of equity method investment securities” included in non-operating expense and the unamortized investment difference shall be first reduced. When the recoverable amount is recovered after the recognition of impairment loss, the reversal of impairment loss can be recognized as income up to the previously recorded impairment loss. The book value of the equity method investment securities after the reversal of the impairment loss cannot exceed the book value calculated as if the impairment loss would not been originally recognized. The reversal of the impairment loss recognized against the unamortized investment difference is not allowed.

- Translation of financial statements of overseas investees

For overseas investees whose financial statements are prepared in foreign currencies, the equity method of accounting is applied after assets and liabilities are translated in accordance with the accounting treatments for the translation of the financial statements of overseas’ subsidiaries for consolidated financial statements. The Company’s proportionate share of the difference between assets net of liabilities and stockholders’ equity after translation into Korean won is accounted for as “increase (decrease) in equity of associates” included in accumulated other comprehensive income (loss). f. Property, Plant and Equipment

Property, plant and equipment are stated at cost (acquisition cost or manufacturing cost plus expenditures directly related to preparing the assets ready for use). Assets acquired from investment-in-kind, by donation or free of charge in other ways are stated at fair value. However, certain assets, for which the revaluation method in accordance with the Korean Assets Revaluation Act or revaluation model in accordance with the amendment to SKAS No. 5 is selected, are recorded at revalued amounts.

Expenditures after acquisition or completion that increase future economic benefit in excess of the most recently assessed capability level of the asset are capitalized and other expenditures are charged to expense as incurred.

In accordance with the Company’s policy, borrowing costs in relation to the manufacture, purchase, construction or development of assets are charged to current operations as incurred.

When the expected future cash flow from use or disposal of the property, plant and equipment is lower than the carrying amount due to obsolescence, physical damage or other causes, the carrying amount is adjusted to the recoverable amount (the higher of net sales price or value in use) and the difference is recognized as an impairment loss. When the recoverable amount subsequently exceeds the carrying amount of the impaired asset, the excess is recorded as a reversal of impairment loss to the extent that the reversed asset does not exceed the carrying amount before previous impairment as adjusted by depreciation. The Company recorded loss on impairment of property, plant and equipment totaling ₩1,629 million and ₩1,277 million and recovery of loss on impairment of those totaling ₩41 million and ₩2,991 million for the years ended December 31, 2010 and 2009, respectively.

Depreciation is computed by the straight-line method based on the useful lives of the related units of property, plant and equipment as summarized below. Depreciation related to the manufacture of other assets is included in the manufacturing cost whereas other depreciation is included in selling and administrative expenses.

Description Useful lives(years)

Buildings 3~60 Structures 2~40 Machinery 2~20 Others 2~20 g. Intangible Assets

Intangible assets are initially recognized at acquisition cost (purchase cost plus expenditures directly related to preparing the asset ready for use) and subsequently presented at amortized cost. Development cost is amortized over 5 ~20 years using the straight-line method when it can be used or sold and intangible assets other than development cost are amortized using the straight-line method over the useful lives as summarized below. Amortization related to the manufacture of other assets is included in the manufacturing cost of the assets whereas other amortization is included in selling and administrative expenses.

Description Useful lives(years)

Goodwill 5~20 Industrial rights 5~20 Other intangible assets 5~20

When the recoverable amount (the higher of net sales price or value in use) of intangible assets is significantly lower than the carrying amount due to obsolescence and other, the difference is recognized as an impairment loss. When the recoverable amount subsequently exceeds the carrying amount of the impaired asset, the excess is recorded as a reversal of impairment loss to the extent that the reversed asset does not exceed the carrying amount before previous impairment as adjusted by amortization. The Company recorded loss on impairment of intangible assets totaling ₩44,681 million and ₩8,068 million for the years ended December 31, 2010 and 2009, respectively.

Doosan Construction & Engineering Co., Ltd., a subsidiary of the Company, recorded the negative goodwill which was the excess of the market value of the transferred net asset over the acquisition cost from the merger with other subsidiaries.

The negative goodwill is amortized to net income over the weighted useful lives of non-monetary depreciation (including amortizing) assets using straight-line method. h. Government Subsidies and Others

Government subsidies and contributions for construction granted for the purpose of acquisition of certain assets are recorded as a deduction from the assets granted or other assets acquired for the temporary use of the assets granted. When the related assets are acquired, they are recorded as a deduction from the acquired assets and offset against the depreciation of the acquired assets over their useful lives. In addition, government subsidies and contributions for construction without any repayment obligation is offset against the related expenses for which they are intended to compensate, however, if there is no matching expense, they are recorded as operating or non-operating income depending on whether they are directly related to the Company’s principal operating activities. Government subsidies and contributions for construction with a repayment obligation are recorded as a liability. i. Present Value Discount for Assets and Liabilities

Receivables or payables from long-term installment transactions, long-term loans/borrowings or the other similar transactions are stated at present value which is determined by discounting total amounts receivable or payable in the future using the effective interest rate, if the nominal value is significantly different from the present value. The discount or premium resulting from the determination of present value is reported in the statements of financial position as a direct deduction from or addition to the nominal value of the related receivables or payables and the amortization by the effective interest rate method is included in the period income (loss). j. Bonds and Discounts on Bonds

Discounts on bonds are amortized over the redemption period of the bonds using the effective interest rate method, which are recognized as interest expense. k. Accrued Severance Indemnities

In accordance with the Company's policy, all employees with more than one year of service are entitled to receive lump-sum severance payments upon termination of their employment, based on their current rates of salary and length of service. The accrual for severance indemnities is computed as if all employees were to terminate at the end of the reporting period and amounted to ₩1,161,625 million and ₩1,111,993 million as of December 31, 2010 and 2009, respectively.

The Company has insured a portion of its obligations for severance indemnities by making deposits with Dongyang Life Insurance and other, which will be directly paid to employees, and records them as deposits for severance insurance which are directly deducted from accrued severance indemnities.

Actual payments for severance indemnities amounted to ₩147,997 million and ₩200,174 million for the years ended December 31, 2010 and 2009, respectively.

l. Provisions

The Company recognizes a provision for a liability with uncertain timing or amount when (i) there is a present obligation of the Company arising from past events, (ii) it is highly likely that an outflow of resources will be required to settle the obligation, and (iii) the amount for the settlement of the obligation can be reliably measured. If there is a significant difference between the nominal value and present value of such provision, the provision is stated at the present value of the expenditures expected to be required to settle the obligation.

Where the expenditure required to settle a provision is expected to be reimbursed by another party, the reimbursement is recognized as a separate asset when, and only when, it is virtually certain that reimbursement will be received if the Company settles the obligation. The expense generated by the provision is presented net of the amount of expected reimbursement. m. Translation of Assets and Liabilities Denominated in Foreign Currency

Transactions denominated in foreign currencies are recorded in Korean won translated at the exchange rate prevailing on the transaction date and the resulting gain (loss) from foreign currency transactions is included in non-operating income (expense). Monetary assets and liabilities denominated in foreign currency are translated into Korean won at the Base Rates announced by Money Brokerage Services, Ltd. at the end of the reporting period, which were ₩1,138.90 and ₩1,167.60 to USD 1.00 at December 31, 2010 and 2009, respectively, and the resulting gain (loss) from foreign currency translation is included in non-operating income (expense). n. Derivative Instruments

The Company records rights and obligations arising from derivative instruments in assets and liabilities, which are stated at fair value. Gains and losses that result from the changes in the fair value of derivative instruments are recognized in current earnings. However, for derivative instruments that cash flow hedge accounting applies to, the effective portion of the gain or loss on the derivative instruments are recorded as gain (loss) on valuation of derivatives included in accumulated other comprehensive income (loss). o. Leases

A lease is classified as a finance lease or an operating lease depending on the extent of transfer to the Company of the risks and rewards incidental to ownership. If a lease meets any one of the following criteria, it is accounted for as a finance lease:

 The lease transfers ownership of the asset to the lessee by the end of the lease term;  The lessee has the option to purchase the asset at a bargain price and it is certain that the option will be exercised;  The lease term is for the major part (75% or more) of the economic life of the asset even if title is not transferred;  At the date of lease commencement the present value of the minimum lease payments amounts to at least substantially all (90% or more) of the fair value of the leased asset; or  The leased assets are of such a specialized nature that only the Company can use them without major modifications.

All other leases are treated as operating leases.

(1) Lessees

For operating leases, lease payments excluding guaranteed residual value are recognized as an expense on a straight-line basis over the lease term and contingent rent is expensed as incurred. Finance leases are recognized as assets and liabilities at the lower of fair value of the leased property or the present value of the minimum lease payments discounted using the implicit interest rate of the lessor (or the Company’s incremental borrowing rate if the implicit interest rate is not practicable to determine). Any initial direct costs incurred by the Company are added to the amount recognized as an asset. The depreciation policy for depreciable leased assets is consistent with that for the similar depreciable assets that are owned by the Company. Annual minimum lease payments excluding guaranteed residual value is allocated to interest expense, which is calculated using the effective interest rate, and finance lease repayment amount. Contingent rent relating to financing are charged as expenses in the periods in which they are incurred, however, if the amount is material, it is allocated to principal and interest, respectively, over the remaining lease term.

(2) Lessors

For operating leases, lease payments on a lease contract are recognized as other income on a straight- line basis over the lease term. For finance leases, lessors are required to present finance lease assets as receivables in statements of financial position, at an amount equal to the fair value of the leased property at the inception of lease and required to recognize the lease payments received as repayment of the finance lease receivables and interest income. p. Revenue Recognition

Revenue generated from sale of goods is recognized upon delivery; however, revenue is recognized when the terms of the sales have been fully met if there are sales terms related with post-delivery.

In the case of returnable sales, revenue and cost generated from sale of goods are eliminated respectively and gross margin is appropriated as reserve for returned goods. The costs expected from returned goods is additionally reflected in the provision related. Reserve for returned goods for refund amounted to ₩6,051 million and ₩6,910 million for the years ended December 31, 2010 and 2009, respectively.

Interest is recognized on a time proportion basis that takes into account the effective yield on the asset. Dividend is recognized when the stockholders’ right to receive payment is established. Royalties is recognized on an accrual basis in accordance with the economic substance of the relevant agreement.

Revenue from construction projects is recognized using the percentage-of-completion method, measured by the ratio of actual costs incurred to estimated total costs for each project. Revenue from housing projects is recognized using the percentage-of-completion method starting after the sales contracts is made. When loss from service or construction contract is probable, the loss is immediately recognized as provision for construction losses and charged to cost of sales or cost of construction in the same period. In addition, when the Company has an obligation for construction warranty after the construction or service is completed, total estimated construction warranty expense is included in cost of construction or service in the fiscal year during which the construction is completed or service is rendered, and records the provision for construction warranty liability in the statements of financial position.

q. Loss on Impairment

Real estate for the purpose of investment is recorded as other non-current investments. When the recoverable amounts of investments in properties are significant below the book value caused by obsolescence, physical impairment and sharp decrease in market value, the difference is reflected in current earnings. The Company recorded loss on impairment of other non-current investments amounted to ₩32,617 million for the year ended December 31, 2010. r. Income Tax

The Company recognizes deferred income tax assets or liabilities for the temporary differences between the carrying amount of an asset and liability for the financial reporting purposes and the amounts used for income tax purposes. A deferred tax liability is generally recognized for all taxable temporary differences with some exceptions and a deferred tax asset is recognized to the extent when it is probable that taxable income will be available against which the deductible temporary difference can be utilized in the future. Deferred income tax asset (liability) is classified as current or non-current asset (liability) depending on the classification of related asset (liability) in the statements of financial position. Deferred income tax asset (liability), which does not relate to specific asset (liability) account in the statements of financial position such as deferred income tax asset recognized for tax loss carryforwards, is classified as current or non- current asset (liability) depending on the expected reversal period. Deferred income tax assets and liabilities in the same tax jurisdiction and in the same current or non-current classification are presented on a net basis. Current and deferred income tax expense are included in income tax expense in the statement of operations and additional income tax or tax refunds for the prior periods are included in income tax expense for the current period when recognized. However, income tax resulting from transactions or events, which was directly recognized in stockholders’ equity in current or prior periods, or business combinations, is directly adjusted to equity account or goodwill (or negative goodwill). s. Currency Translation for Foreign Operations

Assets and liabilities of a foreign branch or company subject to the equity method of accounting for investments are translated into Korean won at the rates of exchange in effect at the end of the reporting period, while their equity is translated at the exchange rate at the time of transaction, and statement of operations’ accounts at the average rate over the period.

Resulting translation gains and losses are recorded as accumulated other comprehensive income (loss). Corresponding gains and losses are recognized as gain or loss when the foreign branch or company is liquidated or sold. t. Use of Estimates

The Company’s management uses reasonable estimates and assumptions in preparing the accompanying consolidated financial statements in accordance with accounting principles generally accepted in the Republic of Korea. The estimates and assumptions can change according to additional experience, changes in circumstances, new information and other and may be different from actual results.

(3) Basis for Presenting Consolidated Financial Statements a. Offset of Investments in Subsidiaries against Stockholders’ Equity

As of the date of initial investment in subsidiaries, the Company’s investments in subsidiaries are offset against their corresponding stockholders’ equity of subsidiaries. Difference between the acquisition cost and the Company’s proportionate equity in the fair value of net assets of subsidiaries upon acquisition (“Investment difference”) is considered (negative) goodwill.

When investment in subsidiaries is acquired during a period, the Parent prepares the consolidated financial statements using the subsidiaries’ financial statements (including the interim financial statements) as of the closest date to the date of acquisition of the investment. b. Treatment of Investment Difference

The excess of the acquisition cost over the Company’s proportionate equity in the fair value of net assets of the investee upon acquisition are considered goodwill and the Company amortized goodwill over useful lives on a straight-line method. The excess of the Company’s proportionate equity in the fair value of net assets of the investee upon acquisition over the acquisition cost are considered negative goodwill, which is reversed over the weighted average useful lives of depreciable non-monetary assets of the investee and is reversed at the time of disposal of non-depreciable non-monetary assets. c. Elimination of Inter-company Unrealized Gains and Losses

Significant unrealized gains and losses from inter-company transactions are fully eliminated. d. Translation of Financial Statements of Subsidiaries

For overseas subsidiaries whose financial statements are prepared in foreign currencies, accounts of consolidated statements of financial position are translated by the exchange rate at the end of the reporting period, accounts of consolidated statements of income are translated by the average exchange rate of the reporting period. Net translation adjustments are recorded as a component of stockholders’ equity.

For consolidated statements of cash flows, beginning balance of cash are translated by the exchange rate at the end of the prior reporting period and ending balance of cash are translated by the exchange rate at the end of the reporting period. Net translation adjustments are recorded as changes in cash according to translation.
