GENERAL INFORMATION Tenaris S.A. (the "Company"), a Luxembourg corporation (societe anonyme holding), was incorporated on December 17, 2001, as a holding company in steel pipe manufacturing and distributing operations. The Company holds, either directly or indirectly, controlling interests in various subsidiaries. References in these financial statements to "Tenaris" refer to Tenaris S.A. and its consolidated subsidiaries. A list of the Company's subsidiaries is included in Note 32. Tenaris shares are listed on the New York, Buenos Aires, Milan, and Mexico City Stock Exchanges. These consolidated financial statements were approved for issue by the Company's Board of Directors on February 28, 2007. II. ACCOUNTING POLICIES A Basis of presentation The Consolidated Financial Statements of Tenaris and its subsidiaries have been prepared in accordance with International Financial Reporting Standards ("IFRS"). The consolidated financial statements are presented in thousands of U.S. dollars ("$"). Certain comparative amounts have been reclassified to conform to changes in presentation in the current year. The preparation of consolidated financial statements in conformity with IFRS requires management to make certain accounting estimates and assumptions that might affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the balance sheet dates, and the reported amounts of revenues and expenses during the reporting years. Actual results may differ from these estimates. B Group accounting (1) Subsidiary companies Subsidiary companies are entities which are controlled by Tenaris as a result of its ownership of more than 50% of the voting rights or its ability to otherwise govern an entity's financial and operating policies. Subsidiaries are consolidated from the date on which control is exercised by the Company and are no longer consolidated from the date that the Company ceases to have control. The purchase method of accounting is used to account for the acquisition of subsidiaries by Tenaris. The cost of an acquisition is measured as the fair value of the assets given, equity instruments issued and liabilities incurred or assumed at the date of acquisition, plus costs directly attributable to the acquisition. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. The excess of the cost of acquisition over the fair value of Tenaris share of the identifiable net assets acquired is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in the income statement. Material intercompany transactions and balances between Tenaris subsidiaries have been eliminated in consolidation. However, since the functional currency of some subsidiaries is its respective local currency, some financial gains (losses) arising from intercompany transactions are generated. These are included in the consolidated income statement under Financial results. See Note 32 for the list of the consolidated subsidiaries. 3 B Group accounting (Cont'd.) (2) Associated companies Investments in associated companies are accounted for by the equity method of accounting and initially recognized at cost. Associated companies are companies in which Tenaris owns between 20% and 50% of the voting rights or over which Tenaris has significant influence, but does not have control. Unrealized results on transactions between Tenaris and its associated companies are eliminated to the extent of Tenaris' interest in the associated companies. Unrealized losses are also eliminated but considered an impairment indicator of the asset transferred. Accounting policies of associated companies have been changed where necessary to ensure consistency with the policies adopted by the Company. The Company's pro-rata share of earnings in associated companies is recorded in Equity in earnings of associated companies. The Company's pro-rata share of changes in other reserves is recognized in reserves in the Statement of Changes in Equity. The Company's investment in Ternium S.A. ("Ternium") has been accounted for under the equity method, as Tenaris has significant influence as defined by IAS 28, Investments in Associates. At December 31, 2006, Tenaris held 11.46% of Ternium's common stock. The Company's investment in Ternium is carried at incorporation cost plus proportional ownership of Ternium's earnings and other shareholders' equity accounts. Because the exchange of its holdings in Amazonia and Ylopa for shares in Ternium was considered to be a transaction between companies under common control of San Faustin N.V., Tenaris recorded its initial ownership interest in Ternium at $229.7 million, the carrying value of the investments exchanged. This value was $22.6 million less than Tenaris' proportional ownership of Ternium's shareholders' equity at the transaction date. As a result of this treatment, Tenaris's investment in Ternium will not reflect its proportional ownership of Ternium's net equity position. Ternium carried out an initial public offering of its shares on February 1, 2006, listing its shares on the New York Stock Exchange. See Note 12 for a list of principal associated companies. C Segment information Until September 30, 2006 Tenaris reported under four business segments: Seamless, Welded and Other Metallic Products, Energy and Other. The acquisition of Maverick Tube Corporation and its subsidiaries ("Maverick") on October 5, 2006, and the sale of a significant ownership in Dalmine Energie on December 1, 2006 led to a reassessment in the definition of operating segments previously used by Tenaris. Together with the reassessment, Tenaris early adopted IFRS 8 "Operating Segments" as from the year ended December 31, 2006. As from these Financial Statements, Tenaris changed its segment reporting into three major business segments: Tubes, Projects and Other. The Tubes segment includes the operations that consist in the production and selling of both seamless and welded steel tubular products mainly for energy and industrial applications. The Projects segment includes the operations that consist in the production and selling of welded steel pipe products mainly used in the construction of major pipeline projects. The Other segment includes the operations that consist in the production and selling of sucker rods, hot briquetted iron, steel electrical conduit and other metallic products. Corporate general and administrative expenses have been allocated to the Tubes segment. Comparative amounts have been re-presented to conform to new disclosure. 4 C Segment information (Cont'd.) Tenaris groups its geographical information in five areas: South America, Europe, North America, Middle East and Africa, and Far East and Oceania. For purposes of reporting geographical information, net sales are attributable to geographical areas based on the customer's location; allocation of assets and capital expenditures and associated depreciation and amortization are based on the geographic location of the assets. D Foreign Currency Translation (1) Functional currency IAS 21(revised) defines the functional currency as the currency of the primary economic environment in which an entity operates. The functional currency of Tenaris S.A. is the U.S. dollar. The U.S. dollar is the currency that best reflects the economic substance of the underlying events and circumstances relevant to Tenaris global operations. Generally, the functional currency of Tenaris's subsidiaries is the respective local currency. Tenaris Argentine operations, however, which consist of Siderca S.A.I.C. ("Siderca") and its Argentine subsidiaries, have determined their functional currency to be the U.S. dollar, based on the following considerations: o Sales are mainly negotiated, denominated and settled in U.S. dollars. If priced in a currency other than the U.S. dollar, the price considers exposure to fluctuation in the rate of exchange rate versus the U.S. dollar; o Prices of critical raw materials and inputs are priced and settled in U.S. dollars; o The exchange rate of the currency of Argentina has long-been affected by recurring and severe economic crises; o Net financial assets and liabilities are mainly received and maintained in U.S. dollars. In addition to Siderca, the Company's distributing subsidiaries and intermediate holding subsidiaries also use the U.S. dollar as their functional currency, reflecting the transaction environment and cash flow of these operations. (2) Translation of financial information in currencies other than the functional currency Results of operations for subsidiaries whose functional currencies are not the U.S. dollar are translated into U.S. dollars at the average exchange rates for each quarter of the year. Balance sheet positions are translated at the end-of-year exchange rates. Translation differences are recognized in equity as currency translation adjustments. In the case of a sale or other disposal of any such subsidiary, any accumulated translation difference would be recognized in income as a gain or loss from the sale. (3) Transactions in currencies other than the functional currency Transactions in currencies other than the functional currency are accounted for at the exchange rates prevailing at the date of the transactions. Gains and losses resulting from the settlement of such transactions, including intercompany transactions, and from the translation of monetary assets and liabilities denominated in currencies other than the functional currency, are recorded as gains and losses from foreign exchange and included in Financial results in the income statement. E Property, plant and equipment Property, plant and equipment are recognized at historical acquisition or construction cost less accumulated depreciation and impairment losses. Property, Plant and Equipment acquired through acquisitions accounted for as business combinations have been valued initially at the fair market value of the assets acquired. 5 E Property, plant and equipment (Cont'd.) Major overhaul and rebuilding expenditures are capitalized as property, plant and equipment only when the investment enhances the condition of assets beyond its original condition. The carrying amount of the replaced part is derecognized. Ordinary maintenance expenses on manufacturing properties are recorded as cost of products sold in the year in which they are incurred. Borrowing costs that are attributable to the acquisition or construction of certain capital assets are capitalized as part of the cost of the asset, in accordance with IAS 23, Borrowing Costs. Capital assets for which borrowing costs may be capitalized are those that require a substantial period of time to prepare for their intended use. Depreciation is calculated using the straight-line method to depreciate the cost of each asset to its residual value over its estimated useful life, as follows: Buildings and improvements 30-50 years Plant and production equipment 10-20 years Vehicles, furniture and fixtures, and other equipment 4-10 years The residual values and useful lives of significant plant and equipment are reviewed, and adjusted if appropriate, at each year-end date. Any charges from such reviews are included in Cost of sales in the income statement. Management's reestimation of assets useful lives, performed in accordance with IAS 16, did not materially affect depreciation expenses for 2006. Tenaris depreciates each significant part of an item of property, plant and equipment for its different production facilities that (i) can be properly identified as an independent component with a cost that is significant in relation to the total cost of the item, and (ii) has a useful operating life that is different from another significant part of that same item of property, plant and equipment. Gains and losses on disposals are determined by comparing net proceeds with the carrying amount of assets. These are included in Other operating income or Other operating expenses in the income statement. F Intangible assets (1) Goodwill Goodwill represents the excess of the acquisition cost over the fair value of the Tenaris' share of net assets acquired as part of business combinations. In accordance with IFRS 3, beginning January 1, 2005, goodwill is considered to have an indefinite life and is not amortized, but is subject to annual impairment testing. In the event of impairment, impairment losses on goodwill are not reversed. No impairment losses related to goodwill were recorded by Tenaris during the three years covered by these financial statements. Goodwill is included in `Intangible assets, net' on the balance sheet. Goodwill is allocated to cash-generating units for the purpose of impairment testing. The allocation is made to those cash-generating units expected to benefit from the business combination which generated the goodwill being tested. Negative goodwill represents an excess of the fair value of identifiable net assets acquired in a business combination over the cost of the acquisition. IFRS 3 requires negative goodwill to be recognized immediately as a gain in the income statement. 6 F Intangible assets (Cont'd.) (1) Goodwill (Cont'd.) During 2004 International Financial Reporting Standard (IFRS) 3, "Business Combinations" was issued, which was applied by Tenaris for all business combinations that occurred after March 31, 2004. As per this standard, prior to January 1, 2005 goodwill was amortized on a straight line basis over its estimated useful life, not to exceed 15 years, and tested for impairment at each balance sheet date in the event indicators of impairment were present. As required by IFRS 3, Tenaris ceased amortization of goodwill for periods beginning on or after January 1, 2005. In addition, accumulated amortization as of December 31, 2004 has been netted against the cost of the goodwill. For years ending on or after December 31, 2005 goodwill is required to be tested annually for impairment, as well as when there are indicators of impairment. Amortization of goodwill expense included in the year ended December 31, 2004 amounted to $9.4 million. Upon the adoption of IFRS 3, which must be adopted together with the revised IAS 38, Intangible Assets, and IAS 36, Impairment of Assets, previously accumulated negative goodwill is required to be derecognized through an adjustment to retained earnings. The derecognition of negative goodwill in this manner resulted in an increase of $110.8 million in the opening balance of the Company's equity at January 1, 2005. Amortization of negative goodwill in income amounted to $9.0 million in the year ended December 31, 2004. (2) Information systems projects Costs associated with developing or maintaining computer software programs are generally recognized as an expense as incurred. However, costs directly related to the development, acquisition and implementation of information systems are recognized as intangible assets if it is probable they have economic benefits exceeding one year. Information systems projects recognized as assets are amortized using the straight-line method over their useful lives, not exceeding a period of 3 years. Amortization charges are classified as Selling, general and administrative expenses in the income statement. (3) Licenses, patent and trademarks Expenditures on acquired patents, trademarks, technology transfer and licenses are capitalized and amortized using the straight-line method over their estimated useful lives, not exceeding a period of 3 years. o (4) Research and development Research expenditures as well as development costs that do not fulfill the criteria for capitalization are recorded as cost of sales in the income statement as incurred. Research and development expenditures included in cost of sales for the years 2006, 2005 and 2004 totaled $46.9 million , $34.7 million and $26.3 million, respectively. (5) Customer relationships intangible asset acquired in a business combination In accordance with IFRS 3 and IAS 38, Tenaris has recognized the value of customer relationships separately from goodwill attributable to the acquisition of Maverick, as further disclosed in Note 28. Customer relationships are amortized over a useful average life of approximately 14 years. 7 G Impairment of non financial assets In accordance with IFRS 3 (Business Combinations) and the related revised versions of IAS 36 (Impairment of Assets) and IAS 38 (Intangible Assets), long-lived assets, including identifiable intangible assets and goodwill are regularly reviewed for impairment. Intangible assets with indefinite life, including goodwill, are subject to at least an annual impairment test for possible impairment whereas, the remaining long lived assets are tested whenever events or changes in circumstances indicate that the balance sheet carrying amount of the asset may not be recoverable. To carry out these tests, assets are grouped into cash generating units (CGUs). The value in use of these units is determined on the basis of the present value of net future cash flows which will be generated by the assets tested. Cash flows are discounted at discount rates that reflects specific country and currency risks. H Other Investments Other investments consist primarily of investments in financial debt instruments. All of Tenaris investments are classified as financial assets "at fair value through profit or loss". As explained in section IV, Tenaris applied the transition provisions of IAS 39 and designated as "financial assets carried at fair value through profit or loss" the investments that were previously recognized as "available-for-sale". Purchases and sales of financial investments are recognized as of the trade date, which is the date that Tenaris commits to purchase or sell the investment, and which is not significantly different from the actual settlement date. The change in fair value of financial investments designated as held at fair value through profit or loss is charged to Financial results in the income statement. Income from financial investments is recognized in Financial results in the income statement. Interest receivable on investments in debt securities is calculated using the effective interest method. The fair values of quoted investments are based on current mid prices. If the market for a financial investment is not active or the securities are not listed, Tenaris estimates fair value by using standard valuation techniques. I Inventories Inventories are stated at the lower of cost (calculated principally on the first-in-first-out "FIFO" method) and net realizable value. The cost of finished goods and goods in process is comprised of raw materials, direct labor, other direct costs and related production overhead costs. Tenaris estimates net realizable value of inventories item by item or by grouping, where applicable, similar or related items. Net realizable value is the estimated selling price in the ordinary course of business, less any estimated costs of completion and selling expenses. Goods in transit at year end are valued at supplier invoice cost. Tenaris establishes an allowance for obsolete or slow-moving inventory related to finished goods, supplies and spare parts. For slow moving or obsolete finished products, an allowance is established for based on management's analysis of product aging. An allowance for slow-moving inventory of supplies and spare parts is established based on management's analysis of such items to be used as intended and the consideration of potential obsolescence due to technological changes. J Trade receivables Trade receivables are recognized initially at fair value, generally original invoice amount. Tenaris analyzes its trade accounts receivable on a regular basis and, when aware of a specific client's difficulty or inability to meet its obligations to Tenaris, impairs any amounts due by means of a charge to an allowance for doubtful accounts receivable. Additionally, this allowance is adjusted periodically based on the aging of receivables. 8 K Cash and cash equivalents Cash and cash equivalents are comprised of cash in banks, short-term money market funds and highly liquid short-term securities with a maturity of less than 90 days at the date of purchase. Assets recorded in cash and cash equivalents are carried at fair market value, or at historical cost which approximates fair market value. For the purposes of the cash flow statement, cash and cash equivalents is comprised of cash, bank accounts and short-term highly liquid investments and overdrafts. On the balance sheet, bank overdrafts are included in borrowings in current liabilities. L Shareholders' Equity (1) Basis of presentation The consolidated statement of changes in equity includes: o The value of share capital, legal reserve, share premium and other distributable reserve calculated in accordance with Luxembourg Law; o The currency translation adjustments, retained earnings, minority interest and other reserves calculated in accordance with IFRS; (2) Share Capital Ordinary shares are classified as equity. (3) Dividends Paid by Tenaris to Shareholders Dividends payable are recorded in Tenaris' financial statements in the year in which they are approved by the Company's shareholders, or when interim dividends are approved by the Board of Directors in accordance with the by-laws of the Company. Dividends may be paid by Tenaris to the extent that it has distributable retained earnings, calculated in accordance with Luxembourg law. As a result, retained earnings included in the consolidated financial statements may not be wholly distributable. See Note 26. M Borrowings Borrowings are recognized initially for an amount equal to the proceeds received net of transaction costs. In subsequent years, borrowings are stated at amortized cost. N Income Taxes - Current and Deferred Under present Luxembourg law, the Company is not subject to income tax, withholding tax on dividends paid to shareholders or capital gains tax payable in Luxembourg as long as the Company maintains its status as a "1929 Holding Billionaire Company". Following a previously announced decision by the European Commission, the Grand-Duchy of Luxembourg has terminated its 1929 holding company regime, effective January 1, 2007. However, under the implementing legislation, pre-existing publicly listed companies -including Tenaris- will be entitled to continue benefiting from their current tax regime until December 31, 2010. The current income tax charge is calculated on the basis of the tax laws in effect in the countries where the Company's subsidiaries operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions when appropriate. 9 N Income Taxes - Current and Deferred (Cont.) Deferred income taxes are calculated applying the liability method on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. The principal temporary differences arise from fair value adjustments of assets acquired in business combinations, the effect of currency translation on fixed assets, depreciation on property, plant and equipment, valuation of inventories and provisions for pensions. Deferred tax assets are also recognized for net operating loss carry-forwards. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the time period when the asset is realized or the liability is expected to be settled, based on tax laws that have been enacted or substantively enacted by the balance sheet date. Deferred tax assets are recognized to the extent it is probable that future taxable income will be available to utilize those recognized deferred tax assets against such income. O Employee-related liabilities (a) Employee severance indemnity Employee severance indemnity costs are assessed annually using the projected unit credit method. Employee severance indemnity obligations are measured at the present value of the estimated future cash outflows, based on actuarial calculations provided by independent advisors and in accordance with current legislation and labor contracts in effect in each respective country. The cost of this obligation is charged to the income statement over the expected service lives of employees. This provision is primarily related to the liability accrued for employees at Tenaris' Italian and Mexican subsidiaries. (b) Defined benefit pension obligations Certain officers of Tenaris are covered by defined benefit employee retirement plans designed to provide post-retirement, termination and other benefits. Post-retirement costs are assessed using the projected unit credit method. Post-retirement obligations are measured at the present value of the estimated future cash outflows, based on actuarial calculations provided by independent advisors. Benefits provided under one of Tenaris's plans are provided in U.S. dollars, and are calculated based on seven-year salary averages. Tenaris accumulates assets for the payment of benefits expected to be disbursed by this plan in the form of investments that are subject to time limitations for redemption. These investments are neither part of a specific pension plan nor are they segregated from Tenaris' other assets. As a result, this plan is considered to be "unfunded" under IFRS definitions. In its newly acquired Canadian subsidiary (Prudential Steel Ltd.) Tenaris sponsors funded and unfunded non-contributory defined benefit pension plans that cover substantially all of the employees of its company. The plans provide defined benefits based on years of service and, in the case of salaried employees, final average salary. In addition Tenaris provides an unfunded non-contributory post-employment benefits plan to retirees from salaried employment. Certain other officers and former employees of one specific Tenaris subsidiary are covered by a separate plan defined as "funded" under IFRS definitions. All of Tenaris' plans recognize actuarial gains and losses over the average remaining service lives of employees. 10 O Employee-related liabilities (Cont.) (c) Other compensation obligations Employee entitlements to annual leave and long-service leave are accrued as earned. Other length of service based compensation to employees in the event of dismissal or death is charged to income in the year in which it becomes payable. P Employee statutory profit sharing Under Mexican law, the Company's Mexican subsidiaries are required to pay their employees an annual benefit calculated on a basis similar to that used for local income tax purposes. Employee statutory profit sharing is calculated using the liability method, and is recorded in Current other liabilities and Non-current other liabilities on the balance sheet. Because Mexican employee statutory profit sharing is determined on a basis similar to that used for determining local income taxes, Tenaris accounts for temporary differences arising between the statutory calculation and reported expense as determined under IFRS in a manner similar to the calculation of deferred income tax. Q Provisions and other liabilities Tenaris is subject to various claims, lawsuits and other legal proceedings, including customer claims, in which a third party is seeking payment for alleged damages, reimbursement for losses or indemnity. Tenaris' potential liability with respect to such claims, lawsuits and other legal proceedings cannot be estimated with certainty. Management periodically reviews the status of each significant matter and assesses potential financial exposure. If a potential loss from a claim or proceeding is considered probable and the amount can be reasonably estimated, a liability is recorded. Accruals for loss contingencies reflect a reasonable estimate of the losses to be incurred based on information available to management as of the date of preparation of the financial statements, and take into consideration Tenaris' litigation and settlement strategies. These estimates are primarily constructed with the assistance of legal counsel. As the scope of liabilities become better defined, there may be changes in the estimates of future costs which could have a material adverse effect on its results of operations, financial condition and net worth. If Tenaris expects to be reimbursed for an accrued expense, as would be the case for an expense or loss covered under an insurance contract, and reimbursement is considered virtually certain, the expected reimbursement is recognized as a receivable. R Revenue recognition Tenaris' products and services are sold based upon purchase orders, contracts or upon other persuasive evidence of an arrangement with customers, including that the sales price is known or determinable. Sales are recognized as revenue upon delivery and when collection is reasonably assured. Delivery is defined by the transfer of risk provision of sales contracts and may include delivery to a storage facility located at one of the Company's subsidiaries. Other revenues earned by Tenaris are recognized on the following bases: o Interest income: on the effective yield basis. o Dividend income from investments in other companies: when Tenaris' right to collect is established. S Cost of sales and sales expenses Cost of sales and sales expenses are recognized in the income statement on the accrual basis of accounting. Commissions, freight and other selling expenses, including shipping and handling costs, are recorded in Selling, general and administrative expenses in the income statement. 11 T Earnings per share Earnings per share are calculated by dividing the net income attributable to equity holders of the Company by the daily weighted average number of common shares outstanding during the year. U Derivative financial instruments Accounting for derivative financial instruments and hedging activities is included within the Section III, "Financial Risk Management". III. FINANCIAL RISK MANAGEMENT The multinational nature of Tenaris' operations and customer base expose the company to a variety of risks, including the effects of changes in foreign currency exchange rates and interest rates. To manage the volatility related to these exposures, management evaluates exposures on a consolidated basis to take advantage of logical exposure netting. For a portion of the remaining exposures, the Company or its subsidiaries may enter into various derivative transactions in order to manage potential adverse impacts on the Tenaris' financial performance. Such derivative transactions are executed in accordance with internal policies in areas such as counterparty exposure and hedging practices. A. Financial Risk Factors (i) Foreign exchange rate risk management Tenaris manufactures and sells its products in a number of countries throughout the world and as a result is exposed to foreign exchange rate risk. The purpose of Tenaris' foreign currency hedging program is to reduce the risk caused by short-term changes in exchange rates. Tenaris aims to neutralize the potential negative impact of currency fluctuations in the value of other currencies with respect to the dollar. Because a number of subsidiaries have functional currencies other than the U.S. dollar, the results of hedging activities as reported in accordance with IFRS may not reflect management's assessment of its foreign exchange risk hedging program. (ii) Interest rate risk management Tenaris' financing strategy is to manage interest expense using a mixture of fixed-rate and variable-rate debt. To manage this risk in a cost efficient manner, Tenaris enters into interest rate swaps in which it agrees to exchange with the counterparty, at specified intervals, the difference between fixed and variable interest amounts calculated by reference to an agreed-upon notional principal amount. Tenaris have entered into interest rate swaps related to long-term debt to partially hedge future interest payments, as well as to convert borrowings from floating to fixed rates. (iii) Concentration of credit risk No single customer comprised more than 10% of our net sales in 2006. Tenaris' credit policies related to sales of products and services are designed to identify customers with acceptable credit history, and to allow Tenaris to require the use of credit insurance, letters of credit and other instruments designed to minimize credit risk whenever deemed necessary. Tenaris maintains allowances for impairment for potential credit losses. Derivative counterparties and cash transactions are limited to high credit quality financial institutions. Tenaris has established strict counterparty credit guidelines and normally enter into transactions with investment grade financial institutions. (iv) Liquidity risk Management maintains sufficient cash and marketable securities or credit facilities to finance normal operations. Tenaris also has committed credit facilities and has access to the market for adequately backup its short-term working capital needs. B. Fair value estimation 12 For purposes of estimating the fair value of financial assets and liabilities with maturities of less than one year, the market value was considered. Most borrowings are comprised of variable rate debt or fixed rate debt that in general terms are comparable to market rate. As a result, the fair value of Tenaris' borrowings approximates its current amounts and is not disclosed separately. C. ACCOUNTING FOR DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES Derivative financial instruments are initially recognized in the balance sheet at fair value on the date a derivative contract is entered into and are subsequently remeasured at fair value. As a general rule, Tenaris recognizes the full amount related to the change in fair value of derivative financial instruments in Financial results in the income for the year. Beginning January 1, 2006, Tenaris has adopted hedge accounting treatment, as established by IAS 39, for certain qualifying derivative financial instruments. These transactions are classified as cash flow hedges (mainly currency forward contracts on highly probable forecast transactions and interest rate swaps and collars). The effective portion of the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in equity. Amounts accumulated in equity are recognized in the income statement in the same period than any offsetting losses and gains on the hedged item. The gain or loss relating to the ineffective portion is recognized immediately in the income statement. The fair value of Tenaris derivative financial instruments (asset or liability) continues to be reflected on the Balance Sheet. For transactions designated and qualifying for hedge accounting, <180>Tenaris documents at the inception of the transaction the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedge transactions. At December 31, 2006, the effective portion of designated cash flow hedges amounts to $2.1 million and is included in Other Reserves in equity. Tenaris does not hold or issue derivative financial instruments for speculative trading purposes. IV. IMPACT OF NEW ACCOUNTING PRONOUNCEMENTS Standards early adopted by Tenaris IFRS 8 "Operating Segments" replaces IAS 14 and requires an entity to report financial and descriptive information about its reportable segments (as aggregations of operating segments). Financial information is required to be reported on the same basis as is used internally for evaluating operating segment performance and deciding how to allocate resources to operating segments also giving certain descriptive information. See Section II C. 13 Interpretations and amendments to published standards effective in 2006 (a) IAS 19, Employee Benefits: Actuarial Gains and Losses, Group Plans and Disclosures (Amendment) On December 16, 2004, the International Accounting Standards Board ("IASB") issued International Accounting Standard No. 19, "Employee Benefits: Actuarial Gains and Losses, Group Plans and Disclosures (Amendment)" ("IAS 19"). IAS 19 gives entities the option to recognize actuarial gains and losses in full during the period in which they occur, outside of profit and loss, in the statement of recognized income and expense. Previously, entities were only permitted to recognize actuarial gains and losses in profit and loss either (1) in the period in which they occur or (2) spread over the service life of employees. As Tenaris does not intend to change the accounting policy adopted for recognition of actuarial gains and losses, this amendment did not impact in the Company Financial Statements. (b) IAS 21, The Effects of Changes in Foreign Exchange Rates - Net Investment in Foreign Operations In December 2005, the IASB issued an amendment to IAS 21, The Effects of Changes in Foreign Exchange Rates - Net Investment in Foreign Operations. The amendment clarifies the requirements of IAS 21 regarding an entity's investment in foreign operations. As per the amendment, the entity that has a monetary item that is, in substance, a part of the entity's net investment in that foreign operation may be any subsidiary of the group. Exchange differences on such monetary items are reclassified to the separate component of equity in the financial statements that include the foreign operation and the reporting entity. The application of this amendment from January 1, 2006 did not have a material impact in the Company's financial statements. Management assessed the relevance of other new standards, amendments or interpretations and concluded that they are not relevant to Tenaris. Interpretations and amendments to published standards that are not yet effective and have not been early adopted (a) IFRS 7, Financial Instruments: Disclosure, and a complementary amendment to IAS 1, presentation of financial statements - Capital disclosure IFRS 7 introduces new disclosures about financial instruments such as qualitative and quantitative information about exposures to risks arising from financial instruments. Tenaris will apply IFRS 7 and the amendment to IAS 1 for annual periods beginning on January 1, 2007. (b) IFRIC 9, Reassessment of Embedded Derivatives IFRIC 9 requires an entity to assess whether an embedded derivative is required to be separated from the host contract and accounted for as a derivative when the entity first becomes a party to the contract. Subsequent reassessment is prohibited unless there is a significant change in the terms of the contract. (c) IFRIC 10, Interim Financial Reporting and Impairment Under this interpretation, no reversal to an impairment loss recognized in an interim period in respect of goodwill or an investment in either an equity instrument or a financial asset carried at cost is allowed. Tenaris will apply IFRIC 10 from January 1, 2007, but it is not expected to have any impact on the Company's financial statements. Management assessed the relevance of other new standards, amendments or interpretations not yet effective and concluded that they are not relevant to Tenaris. 14 V.

By application of this method, Tenaris recognizes gains and losses on deferred income tax due to the effect of the change in the value of the Argentine peso on the tax bases of the fixed assets of its Argentine subsidiaries, which have the U.S. dollar as their functional currency. These gains and losses are required by IFRS even though the devalued tax basis of the relevant assets will result in a reduced dollar value of amortization deductions for tax purposes in future periods throughout the useful life of those assets. As a result, the resulting deferred income tax charge does not represent a separate obligation of Tenaris that is due and payable in any of the relevant periods. 9 Earnings and dividends per share Earnings per share are calculated by dividing the net income attributable to equity holders of the Company by the daily weighted average number of ordinary shares in issue during the year.

This amount included the interim dividend paid in November, 2005, in the amount of $0.127 per share or approximately $149.9 million. Tenaris paid the balance of the annual dividend amounting to approximately $204.2 million corresponding to $0.173 per share during 2006. During 2005 Tenaris paid $199.5 million corresponding to $0.169 per share. The ratio of ordinary shares per American Depositary Shares (ADSs) was changed from a ratio of one ADS equal to ten ordinary shares to a new ratio of one ADS equal to two ordinary shares. The implementation date for this change was April 26, 2006, for shareholders of record at April 17, 2006. Earnings per ADS reflected above have been adjusted for this change in the conversion ratio. 19 10 Property, plant and equipment, net Vehicles, Land, Plant and furniture Spare building and production and Work in parts and Year ended December 31, 2006 improvements equipment fixtures progress equipment Total ------------------------------------------------------------------------ Cost Values at the beginning of the year 408,191 5,442,181 126,315 173,715 24,237 6,174,639 Translation differences 9,741 124,256 3,784 16,450 1,047 155,278 Additions 6,527 14,030 931 387,516 5,400 414,404 Disposals / Consumptions (11,842) (34,608) (5,434) (21) (12,559) (64,464) Transfers / Reclassifications 12,633 171,274 19,505 (211,450) 7,731 (307) Increase due to business combinations (see Note 28) 126,003 277,066 26,581 27,557 3,730 460,937 Disposal due to sale of subsidiaries (8,306) (2,233) (3,509) (924) (1,174) (16,146) ------------------------------------------------------------------------ Values at the end of the year 542,947 5,991,966 168,173 392,843 28,412 7,124,341 ------------------------------------------------------------------------ Depreciation Accumulated at the beginning of the year 136,231 3,700,676 100,823 - 6,871 3,944,601 Translation differences 1,865 56,212 2,197 - 330 60,604 Depreciation charge 11,094 174,279 11,332 - 785 197,490 Disposal due to sale of subsidiaries (1,478) (1,562) (2,057) - (651) (5,748) Disposals / Consumptions (38) (8,941) (2,865) - (3) (11,847) Transfers / Reclassifications (733) (2,723) 3,470 - (14) - ------------------------------------------------------------------------ Accumulated at the end of the year 146,941 3,917,941 112,900 - 7,318 4,185,100 ------------------------------------------------------------------------ At December 31, 2006 396,006 2,074,025 55,273 392,843 21,094 2,939,241 ------------------------------------------------------------------------ Vehicles, Land, Plant and furniture Spare building and production and Work in parts and Year ended December 31, 2005 improvements equipment fixtures progress equipment Total ------------------------------------------------------------------------ Cost Values at the beginning of the year 353,416 5,386,286 118,193 84,942 19,263 5,962,100 Translation differences 5,566 (104,101) (244) 388 (844) (99,235) Additions 2,722 10,159 2,494 238,314 10,706 264,395 Disposals / Consumptions (2,043) (9,344) (3,322) - (5,119) (19,828) Transfers / Reclassifications 24,593 118,426 6,843 (150,097) 231 (4) Increase due to business combinations (see Note 28) 23,937 40,755 2,351 168 - 67,211 -------------------------------------------------------------------------- Values at the end of the year 408,191 5,442,181 126,315 173,715 24,237 6,174,639 -------------------------------------------------------------------------- Depreciation Accumulated at the beginning of the year 128,148 3,568,058 94,577 - 6,716 3,797,499 Translation differences 1,778 (37,199) (158) - (376) (35,955) Depreciation charge 13,177 170,491 8,649 - 698 193,015 Disposals / Consumptions (515) (7,047) (2,229) - (167) (9,958) Transfers / Reclassifications (6,357) 6,373 (16) - - - -------------------------------------------------------------------------- Accumulated at the end of the year 136,231 3,700,676 100,823 - 6,871 3,944,601 -------------------------------------------------------------------------- At December 31, 2005 271,960 1,741,505 25,492 173,715 17,366 2,230,038 -------------------------------------------------------------------------- Property, plant and equipment include capitalized interest of $19,686.

Impairment testing of the CGU is carried out and the value in use determined in accordance with the discounted cash flow method. In order to perform the test, Tenaris, uses projections for the next 5 years based on past performance and expectations of market development. After the fifth year a perpetuity rate with no grow up increase was utilized. The discount rates used for these tests are based on Tenaris' weighted average cost of capital adjusted for specific country and currency risks associated with the cash flow projections. Discount rates used range from 9% to 12%. No impairment charge resulted from the impairment tests performed. As explained in Note 28 Tenaris acquired Maverick on October 5, 2006. Goodwill of $1,113 million arised from this acquisition as the difference between the acquisition price and the fair value on the acquisition date of the identifiable tangible and intangible assets and liabilities determined mainly by an independent valuation. On account of the recent date of the transaction, the company's fair value is the same as its transaction value. Accordingly, no impairment needs to be recorded. 12 Investments in associated companies Year ended December 31, 2006 2005 ------------------------------------------ At the beginning of the year 257,234 99,451 Translation differences (4,016) (22,869) Equity in earnings of associated companies 95,260 117,003 Dividends and distributions received - (59,127) Reorganization of Dalmine Energie, Lomond and others 10,014 - Capitalization of convertible loan in Amazonia 40,505 120,058 Increase in equity reserves in Ternium 23,961 2,718 ------------------------------------------ At the end of the year 422,958 257,234 ------------------------------------------ The principal associated companies are: Percentage of ownership and voting rights at December 31, Value at December 31, ------------------------------------------------------------- Company Country of incorporation 2006 2005 2006 2005 ------------------------------------------------------------------------------------------------------------------------ Ternium S.A.

The main covenants on these loan agreements are limitations on liens and encumbrances, restrictions in investments and capital expenditures, limitations in the sale of certain assets and compliance with financial ratios (e.g, leverage ratio and interest coverage ratio calculated on each subsidiary's financial statements). In addition, Tenaris's loan agreement is secured with a pledge of a percentage of Maverick's shares, as explained in Note 28. Tenaris is allowed to make payments such as dividends, repurchase or redemption of shares up to the greater of $475 million or 25% of consolidated net income for the previous fiscal year; once the outstanding amount of Tenaris' facility is less than $425 million, no restrictions will apply. Tenaris' consolidated debt includes $127 million of Dalmine and $26 million of Confab secured by certain properties of these subsidiaries. As of December 31, 2006, Tenaris was in compliance with all of its covenants. The weighted average interest rates before tax shown below were calculated using the rates set for each instrument in its corresponding currency as of December 31, 2006 and 2005. These rates reflect the upward trend in the reference rates. 2006 2005 ----------------- ------------------ Bank borrowings 6.12% 5.14% Other loans 5.50% 4.51% Finance lease liabilities 3.71% 3.14% Breakdown of long-term borrowings by currency and rate is as follows: Non current bank borrowings Year ended December 31, Currency Interest rates 2006 2005 -------------------------------------------------------------------------------------------------- USD Variable 3,140,894 546,921 USD Fixed 10,289 - EURO Variable 40,462 93,621 EURO Fixed 6,246 30,709 JPY Variable - 23,310 JPY Fixed 11,854 17,084 BRS Variable 25,938 23,306 ----------------------------------- 3,235,683 734,951 Less: Current portion of medium and long - term loans (412,631) (99,055) ----------------------------------- Total non current bank borrowings 2,823,052 635,896 ----------------------------------- Non current other loans Year ended December 31, Currency Interest rates 2006 2005 ------------------------------------------------------------------------------------------------- COP Variable 622 - USD Variable 52,853 49,332 ---------------------------------- 53,475 49,332 Less: Current portion of medium and long - term loans (2,996) (10,925) ---------------------------------- Total non current other loans 50,479 38,407 ---------------------------------- 26 20 Borrowings (Cont'd.)

To partially hedge future interest payments, as well as to minimize the effect of floating rates, Tenaris has entered into zero cost interest rate collars. In these contracts, effective as from April 2007, the Company has agreed to exchange with the counterparty, at specified intervals, the difference between interest amounts calculated by reference to an agreed-upon notional principal amount of USD 1,500.0 million, to the extent that it is lower than the floor or greater than the cap established in such contracts.

Based on management's assessment and the advice of legal counsel, it is not anticipated that the ultimate resolution of pending litigation will result in amounts in excess of recorded provisions (Notes 23 and 24) that would be material to Tenaris' consolidated financial position or results of operations. Conversion of tax loss carry-forwards On December 18, 2000, the Argentine tax authorities notified Siderca S.A.I.C. ("Siderca", a subsidiary of the Company organized in Argentina) of an income tax assessment related to the conversion of tax loss carry-forwards into Debt Consolidation Bonds under Argentine Law No. 24.073. The adjustments proposed by the tax authorities represent an estimated contingency of ARP70.2 million (approximately $23.0 million) at December 31, 2006 in taxes and penalties. Based on the views of Siderca's tax advisors, Tenaris believes that the ultimate resolution of the matter will not result in a material obligation. Accordingly, no provision was recorded in these financial statements. Asbestos-related Litigation Dalmine S.p.A. ("Dalmine"), a subsidiary of the Company organized in Italy is currently subject to thirteen civil proceedings for work-related injuries arising from the use of asbestos in its manufacturing processes during the period from 1960 to 1980. In addition, another eighteen asbestos related out-of-court claims and one civil party claim have been forwarded to Dalmine. As of December 31, 2006, the total claims pending against Dalmine were thirty two (of which, three are covered by insurance): during 2006 two new claims were filed four claims were dismissed and one claim was settled. Aggregate settlement costs to date for Tenaris are Euro3.8 million. Dalmine estimates that its potential liability in connection with the claims not yet settled is approximately Euro 12.6 million ($ 16.6 million). Accruals for Dalmine's potential liability are based on the average of the amounts paid by Dalmine for asbestos-related claims plus an additional amount related to some reimbursements requested by the social security authority. The maximum potential liability is not determinable as in some cases the requests for damages do not specify amounts, and instead is to be determined by the court. The timing of payment of the amounts claimed is not presently determinable. 26 Contingencies, commitments and restrictions on the distribution of profits (Cont'd.) Maverick litigation 34 On December 11, 2006, The Bank of New York ("BNY"), as trustee for the holders of the Maverick 2004 4% Convertible Senior Subordinated Notes due 2033 issued pursuant to an Indenture between Maverick and BNY ("Noteholders"), filed a complaint against Maverick and Tenaris in the United States District Court for the Southern District of New York. The complaint alleges that Tenaris's acquisition of Maverick triggered the "Public Acquirer Change of Control" provision of the Indenture. The complaint asserts breach of contract claim against Maverick for refusing to deliver the consideration specified in the Public Acquirer Change of Control provision of the Indenture to Noteholders who tendered their notes for such consideration, seeks a declaratory judgment that Tenaris' acquisition of Maverick was a Public Acquirer Change of Control under the Indenture, and asserts claims for tortuous interference with contract and unjust enrichment against Tenaris. Tenaris believes that these claims are without merit. Accordingly, no provision was recorded in these financial statements. Were plaintiff to prevail, Tenaris estimates that the recovery would be approximately $50 million. European Commission Fine On January 25, 2007, the Court of Justice of the European Commission confirmed the December 8, 1998 decision by the European Commission to fine eight international steel pipe manufacturers, including Dalmine, for violation of European competition laws. Pursuant to the Court's decision, Dalmine is required to pay a fine of Euro10.1 million ($13.3 million). Since the infringements for which the fine was imposed took place prior to the acquisition of Dalmine by Tenaris in 1996, Dalmine's former owner, who had instructed Dalmine to appeal, is required and has acknowledged its responsibility to pay 84.1% of the fine. The remaining 15.9% of the fine will be paid out of the provision that Dalmine established in 1999 for such proceeding. BHP litigation and arbitration proceeding against Fintecna On December 30, 2003 Dalmine and a consortium led by BHP Billiton Petroleum Ltd. ("BHP") settled a litigation concerning the failure of an underwater pipeline. The pipe that was the subject of the litigation with BHP was manufactured and sold, and the tort alleged by BHP took place, prior to the privatization of Dalmine. According to the terms of the settlement, Dalmine paid BHP a total of GBP 108.0 million ($207.2 million), inclusive of expenses. Techint Investments Netherlands B.V. ("Tenet") - the subsidiary party of the Company that was party to the Dalmine privatization contract - commenced arbitration proceedings against Fintecna S.p.A. ("Fintecna"), an Italian state-owned entity and successor to ILVA S.p.A., the former owner of Dalmine, seeking indemnification from Fintecna for any amounts paid or payable by Dalmine to BHP. On December 28, 2004, an arbitral tribunal rendered a final award in the arbitration proceeding against Fintecna, pursuant to which, Fintecna paid Tenaris a total amount of Euro 93.8 million ($127.2 million) on March 15, 2005. Neither party has any further oustanding obligations in respect of the BHP litigation. Commitments Set forth is a description of Tenaris' main outstanding commitments: o Tenaris has transportation capacity agreements with Transportadora de Gas del Norte S.A. (TGN), corresponding to capacity of 1,000,000 cubic meters per day until 2017, the outstanding value of this commitment is approximately $68.0 million. We also expect to obtain additional gas transportation capacity of 315,000 cubic meters per day until 2027. This commitment is subject to the enlargement of the trunk pipelines in Argentina that are expected to be ready by 2008. 35 26 Contingencies, commitments and restrictions on the distribution of profits (Cont'd.) Commitments (Cont'd.) o In July 2004, Tenaris' subsidiary Matesi Materiales Siderurgicos S.A. ("Matesi") entered into a twenty-year agreement with C.V.G. Electrificacion del Caroni, C.A. ("Edelca") for the purchase of electric power under certain take-or-pay conditions, with an option to terminate the contract at any time upon three years notice. The outstanding value of the contract at December 31, 2006 is approximately $65.9million. o In August 2004 Matesi entered into a ten-year off-take contract pursuant to which Matesi is required to sell to Sidor on a take-or-pay basis 29.9% of Matesi's HBI production. In addition, Sidor has the right to increase its proportion on Matesi's production by an extra 19.9% until reaching 49.8% of Matesi's HBI production. Under the contract, the sale price is determined on a cost-plus basis. The contract is renewable for additional three year periods unless Matesi or Sidor objects its renewal more than a year prior to its termination. o Tenaris entered into a contract with Siderar for the supply of steam generated at the power generation facility owned by Tenaris in San Nicolas. Under this contract, Tenaris is required to provide 250 tn/hour of steam, and Siderar has the obligation to take or pay this volume. This outsourcing contract is due to terminate in 2018. In October 2004, Tenaris detected technical problems at its electric power generating facility located in San Nicolas, Argentina during the routine maintenance of the equipment. GE Energy, the generator's manufacturer, assumed the cost of the repairs of the generator, estimated at $9.0 million. Tenaris recognized a receivable with the manufacturer for the cost of the repairs. Tenaris impaired the value of these assets under Property, Plant and Equipment for $11.7 million. The reparation of the generating facility was completed by September 2005. o Under a lease agreement entered into in 2000 between Gade Srl (Italy) and Dalmine relating to a building located in Sabbio Bergamasco and used by Dalmine's former subsidiary, Tad Commerciale, Dalmine is obligated to bid in the auction for the purchase of a building owned by Gade for a minimum amount of EUR 8.3 million ($10.0 million). As of the present, a date for the auction has not been announced. Restrictions on the distribution of profits As of December 31, 2006, shareholders' equity as defined under Luxembourg law and regulations consisted of: (all amounts in thousands of U.S. dollars) Share capital 1,180,537 Legal reserve 118,054 Share premium 609,733 Retained earnings including net income for the year ended December 31, 2006 1,527,096 --------------- Total shareholders equity in accordance with Luxembourg law 3,435,420 --------------- At least 5% of the net income per year as calculated in accordance with Luxembourg law and regulations must be allocated to the creation of a legal reserve equivalent to 10% of share capital. As of December 31, 2006, this reserve is fully allocated and additional allocations to the reserve are not required under Luxembourg law. Dividends can not be paid from this reserve. Tenaris may pay dividends to the extent that it has distributable retained earnings and distributable reserve calculated in accordance with Luxembourg law and regulations, and providing the compliance of the covenant related to restricted payments stated in Note 28. 36 26 Contingencies, commitments and restrictions on the distribution of profits (Cont'd.) Restrictions on the distribution of profits (Cont'd.) At December 31, 2006, the distributable reserve, including retained earnings and profit for the financial year, of Tenaris under Luxembourg law totalled $1,527.1 million, as detailed below. (all amounts in thousands of U.S. dollars) Retained earnings at December 31, 2005 under Luxembourg law 1,171,738 Dividends received 566,831 Other income and expenses for the year ended December 31, 2006 (7,240) Dividends paid (204,233) --------------- Retained earnings at December 31, 2006 under Luxembourg law 1,527,096 --------------- 27 Ordinary shares and share premium Number of ordinary shares 2006 2005 --------------------------------------- At January 1 and December 31 1,180,536,830 1,180,536,830 --------------------------------------- The total of issued and outstanding ordinary shares as of December 31, 2006 is 1,180,536,830 with a par value of $1.00 per share with one vote each. 28 Business combinations and other acquisitions (a) Acquisition of Maverick Tube Corporation ("Maverick") On October 5, 2006, Tenaris completed the acquisition of Maverick, pursuant to which Maverick was merged with and into a wholly owned subsidiary of Tenaris. On that date, Tenaris paid $65 per share in cash for each issued and outstanding share of Maverick's common stock. The value of the transaction at the acquisition date was $3,160 million, including Maverick's financial debt. With operations in the United States, Canada and Colombia, Maverick is a producer of oil country tubular goods (OCTG), line pipe and coiled tubing for use in oil and natural gas wells and other applications, also producing welded pipes for electrical conduits. Maverick has a combined annual capacity of two million short tons of steel pipes with a size range from one-quarter inch to 16 inches. In 2005, Maverick reported net revenues of approximately $1.8 billion, of which 82% were from its energy products division. To finance the acquisition and the payment of related obligations, Tenaris and some of its subsidiaries entered into syndicated loan facilities in an aggregate of $2.7 billion; the balance was met from cash on hand. In connection with the financing of the Maverick acquisition 75% of the issued and outstanding shares of Maverick were pledged. Immediately upon each payment or prepayment under the Tenaris loan agreement, the number of shares subject to the pledge shall be reduced by the percentage by which the aggregate outstanding principal amount of the loans under such agreement is reduced by operation of such payment or prepayment until the aggregate outstanding principal amount of such loans is less than or equal to $ 250 million. In addition, Tamsa and Siderca granted drag-along rights in favor of the lenders under the Tenaris loan agreement with respect to the remaining 25% of the issued and outstanding shares of capital stock of Maverick. Goodwill arising on the acquisition of Maverick, $1,113, million is the difference between the acquisition price and the fair value on the acquisition date of the identifiable tangible and intangible assets and liabilities determined mainly by independent valuation. This goodwill reflects the opportunity for Tenaris to increase its presence in North America, primarily in the OCTG market. Tenaris began consolidating Maverick's balance sheet and results of operations in the fourth quarter of 2006. 37 28 Business combinations and other acquisitions (Cont'd.) (b) Acquisition of a steel pipe business in Argentina On January 31, 2006, Siat S.A., a subsidiary of Tenaris, completed its acquisition of the welded pipe assets and facilities located in Villa Constitucion, province of Santa Fe, Argentina, belonging to Industria Argentina de Acero, S.A. ("Acindar") for $29.3 million. The facilities acquired have an annual capacity of 80,000 tons of welded pipes. (c) Capitalization of Convertible Debt of Consorcio Siderurgia Amazonia, Ltd. ("Amazonia") and Exchange of Interests in Amazonia and Ylopa Servicos de Consultadoria Lda. ("Ylopa") for shares of Ternium S.A. ("Ternium") On February 3, 2005, Ylopa exercised its option to convert the convertible debt it held in Amazonia into common stock. In connection of this conversion, Tenaris recognized a gain of $83.1 million in 2004. As a result, Tenaris' ownership stake in Amazonia increased from 14.5% to 21.2%, and its indirect ownership in Sidor C.A. ("Sidor") increased from 8.7% to 12.6%. On September 9, 2005, the Company exchanged its interests in Amazonia and Ylopa, for 209,460,856 shares in Ternium, a newly-formed subsidiary of San Faustin N.V. (a Netherlands Antilles corporation and the controlling shareholder of Tenaris) to consolidate its Latin American holdings in flat and long steel producers Siderar S.A.I.C., Sidor C.A. and Hylsamex, S.A de C.V. As a result of the exchange, which was carried out based on fair values as determined by an internationally recognized investment bank engaged for this purpose, Tenaris obtained an ownership interest of approximately 17.9% in Ternium. Subsequently, on October 27, 2005, Usinas Siderurgicas de Minas Gerais S.A. ("Usiminas") exchanged its interests in Amazonia, Ylopa and Siderar S.A.I.C., plus additional consideration of approximately $114.1 million provided as a convertible loan, for an equity stake in Ternium. As a result of this transaction, at December 31, 2005, Tenaris' ownership stake in Ternium was reduced to 15.0% of Ternium's outstanding common stock. As this was an equity transaction in Ternium, the effect of $2.7 million at Tenaris' percentage of ownership was recognized in Other reserves in equity. Because the exchange of Tenaris' holdings in Amazonia and Ylopa for shares in Ternium was a transaction between companies under common control, Tenaris initially recorded its ownership interest in Ternium at the carrying value of the investments exchanged. At the transaction date, the carrying value of Amazonia and Ylopa was $229.7 million while Tenaris' proportional ownership in the equity of Ternium at September 30, 2005 amounted to $252.3 million. The difference of $22.6 million between the carrying value of Amazonia and Ylopa and Tenaris' proportional ownership in the equity of Ternium will remain in the future. As a result of this accounting treatment, Tenaris reported value of its investment in Ternium will not reflect its proportional ownership of Ternium's net equity position. In addition, in August 2005, Tenaris extended to Ternium two subordinated convertible loans consisting of principal amount of $39.7 million. The principal amount of these loans at the date issued corresponded to the amount of certain distributions received from Amazonia during the second and third quarters of 2005 in connection with Ternium's participation in Amazonia's financial debt restructuring in 2003. At the date of Ternium's initial public offering ("IPO"), the loans totaled approximately $40.5 million, including accrued interest. Until September 30, 2005, Tenaris recognized its proportional earnings in Amazonia and Ylopa, which amounted to $26.5 million. As from the quarter ended December 31, 2005, Tenaris recognized earnings from its investment in Ternium to the extent of its proportional ownership in Ternium. 38 28 Business combinations and other acquisitions (Cont'd.) (c) Capitalization of Convertible Debt of Consorcio Siderurgia Amazonia, Ltd. ("Amazonia") and Exchange of Interests in Amazonia and Ylopa Servicos de Consultadoria Lda. ("Ylopa") for shares of Ternium S.A. ("Ternium") (Cont'd.) On February 6, 2006, Ternium completed its IPO, issuing an additional 248,447,200 shares (equivalent to 24,844,720 ADS) at a price of $2.00 per share, or $20.00 per ADS. Tenaris received an additional 20,252,338 shares upon the mandatory conversion of its loans to Ternium. In addition to the shares issued to Tenaris, Ternium issued shares to other shareholders corresponding to their mandatory convertible loans. On February 23, 2006, the underwriters of Ternium's IPO exercised an over allotment option under which Ternium issued an additional 37,267,080 shares (equivalent to 3,726,708 ADS). As a result of the IPO and the conversion of loans, as of February 6, 2006, Tenaris' ownership stake in Ternium amounted to 11.46%. The effect of these transactions resulted in an additional increase of the Company's proportional ownership in Ternium's equity of approximately $26.7 million, which Tenaris recognized in Other Reserves in equity. At December 31, 2006, the closing price of Ternium shares as quoted on the New York Stock Exchange was $29.54 per ADS, giving Tenaris' ownership stake a market value of approximately $679 million. At December 31, 2006, the carrying value of Tenaris's ownership stake in Ternium was approximately $408 million. (d) Acquisition of S.C. Donasid S.A. ("Donasid") On May 4, 2005, Tenaris completed the acquisition of 97% of the equity in S.C. Donasid S.A., a Romanian steel producer, for approximately $47.9 million in cash and assumed liabilities. The shares of Siprofer A.G. and Donasid Service S.r.l. were also acquired as part of this transaction. (e) Minority Interest During the year ended December 31, 2006, additional shares of Silcotub and Dalmine were acquired from minority shareholders for approximately $11.2 million. The assets and liabilities arising from the acquisitions are as a follows: Maverick (*) Others Total 2006 Total 2005 ------------------------------------------------------------- Other assets and liabilities (net) (698,163) 5,207 (692,956) (41,755) Property, plant and equipment 438,046 22,891 460,937 67,211 Customer relationships 1,493,800 - 1,493,800 - Goodwill 1,112,885 1,402 1,114,287 769 ------------------------------------------------------------- Net assets acquired 2,346,568 29,500 2,376,068 26,225 Minority interest - 11,181 11,181 (527) ------------------------------------------------------------- Sub-total 2,346,568 40,681 2,387,249 25,698 Cash-acquired 70,660 - 70,660 - ------------------------------------------------------------- Purchase consideration 2,417,228 40,681 2,457,909 25,698 Liabilities paid as part of purchase agreement 743,219 - 743,219 22,594 ------------------------------------------------------------- Total disbursement 3,160,447 40,681 3,201,128 48,292 ------------------------------------------------------------- (*) Includes costs directly attributable to the acquisition. Net cash consideration (total disbursement less cash acquired and common stock issued in acquisition of minority interest) amounted to $ 48,292 at December 31, 2005. The businesses acquired in 2006 contributed revenues of $432.0 million and net income of $14.5 million to Tenaris (not including the financial cost related to the operation recorded in other subsidiaries different from Maverick). Businesses acquired in 2005 did not materially contribute to the Company's revenue and income. 39 28 Business combinations and other acquisitions (Cont'd.) Pro forma data including acquisitions for all of 2006 Had the Maverick transaction been consummated on January 1, 2006, then unaudited pro forma 2006 twelve month Tenaris net sales and net income on continuing operations would have been approximately $9.3 billion and $2.0 billion, respectively. These pro forma results were prepared based on public information and unaudited accounting records maintained under USGAAP prior to acquisition and adjusted by depreciation and amortization of tangible and intangible assets and interest expense of the borrowing incurred for the acquisition ($2.7 billion). Carrying amounts of assets, liabilities and contingent liabilities in Maverick's books, determined in accordance with IFRSs, immediately before the combination are not disclosed separately, as Maverick did not report IFRS information. o Subsequent event: Hydril Company ("Hydril") On February 12, 2007, Tenaris announced that it has entered into a definitive merger agreement to acquire Hydril for $97 per share of Hydril's common stock and $97 per share of Hydril's Class B common stock, payable in cash. Tenaris will finance the acquisition through a combination of cash on hand and debt, for which bank commitments have been secured. The agreement is subject to the receipt of clearance from U.S. antitrust authorities, majority approval of Hydril's shareholders and other customary conditions and is expected to close in the second quarter 2007. Hydril is a North American manufacturer of premium connections and pressure control products for oil and gas drilling and production. For 2006, Hydril reported revenues of $503 million, operating income of $132.2 million and net income of $91.3 million under US GAAP. o o 29 Cash flow disclosures o (i) Changes in working capital Year ended December 31, 2006 2005 2004 ---------------------------------------------------- Inventories (455,567) (101,143) (411,045) Receivables and prepayments (181,878) 1,513 (82,845) Trade receivables (226,678) (387,240) (271,225) Other liabilities 7,605 34,526 (37,443) Customer advances 236,446 (14,156) 72,678 Trade payables 150,555 32,561 108,693 ---------------------------------------------------- (469,517) (433,939) (621,187) ---------------------------------------------------- (ii) Income tax accruals less payments Tax accrued 873,967 568,753 220,376 Taxes paid (817,131) (419,266) (175,717) ---------------------------------------------------- 56,836 149,487 44,659 ---------------------------------------------------- (iii) Interest accruals less payments, net Interest accrued 32,237 29,236 32,683 Interest received 11,150 17,227 11,986 Interest paid (21,478) (44,544) (27,696) ----------------------------------------------------- 21,909 1,919 16,973 ----------------------------------------------------- (iv) Cash and cash equivalents Cash and bank deposits 1,372,329 707,356 311,579 Bank overdrafts (7,300) (24,717) (4,256) Restricted bank deposits (21) (2,048) (13,500) ----------------------------------------------------- 1,365,008 680,591 293,823 ----------------------------------------------------- 30 Discontinued operations 40 Sale of a 75% interest in Dalmine Energie On December 1, 2006, Tenaris completed for $58.9 million the sale of a 75% participation of Dalmine Energie, its Italian supply business, to E.ON Sales and Trading GmbH, a wholly owned subsidiary of E.ON Energie AG ("E.ON") and an indirect subsidiary of E.ON AG. Following consummation of the sale, Tenaris maintains a 25% interest in Dalmine Energie. As a result of this transaction, Tenaris has de-consolidated Dalmine Energie and recognized a $40.0 million gain. As per the sale agreement, Tenaris has an irrevocable option to sell to E.ON, at any time during the one year exercise period (in two years from the date of the sale agreement), its 25% remaining interest in Dalmine Energie for a purchase price in cash of EUR 13.0 million plus interests. Also, E.ON has an irrevocable option to purchase from Tenaris, at any time during the one year exercise period (in two years from the date of the sale agreement), Tenaris' 25% remaining interest in Dalmine Energie for a purchase price in cash of EUR 17.5 million plus interests and adjustments.
