Certain monetary amounts, percentages and other figures included in this half-year report have been subject to rounding adjustments. Accordingly, figures shown as totals in certain tables may not be the arithmetic aggregation of the figures that precede them, and figures expressed as percentages in the text may not total 100% or, as applicable, when aggregated may not be the arithmetic aggregation of the percentages that precede them.

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

This half-year report and any other oral or written statements made by us to the public may contain “forward-looking statements”. Forward looking statements are based on management’s current views and assumptions and involve known and unknown risks that could cause actual results, performance or events to differ materially from those expressed or implied by those statements.

We use words such as “aim”, “will likely result”, “will continue”, “contemplate”, “seek to”, “future”, “objective”, “goal”, “should”, “will pursue”, “anticipate”, “estimate”, “expect”, “project”, “intend”, “plan”, “believe” and words and terms of similar substance to identify forward-looking statements, but they are not the only way we identify such statements. All forward-looking statements are management’s present expectations of future events and are subject to a number of factors and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements. These factors include the risks related to our business discussed under “Principal Risks and Uncertainties”, among them, the following:

·	our ability to implement our business strategy or to grow through acquisitions, joint ventures and other investments;

·	the competitive environment in our business and our industry;

·	our ability to price our products and services in accordance with our strategy;

·	trends in the levels of investment in oil and gas exploration and drilling worldwide;

·	general macroeconomic and political conditions and developments in the countries in which we operate or distribute pipes; and

·	our ability to absorb cost increases and to secure supplies of essential raw materials and energy.

By their nature, certain disclosures relating to these and other risks are only estimates and could be materially different from what actually occurs in the future. As a result, actual future gains or losses that may affect our financial condition and results of operations could differ materially from those that have been estimated. You should not place undue reliance on the forward-looking statements, which speak only as of the date of this half-year report. Except as required by law, we are not under any obligation, and expressly disclaim any obligation to, update or alter any forward-looking statements, whether as a result of new information, future events or otherwise.

COMPANY OVERVIEW

We are a leading global manufacturer and supplier of steel pipe products and related services for the world’s energy industry and for other industrial applications. Our customers include most of the world’s leading oil and gas companies as well as engineering companies engaged in constructing oil and gas gathering, transportation, processing and power generation facilities. Our principal products include casing, tubing, line pipe, and mechanical and structural pipes.

Over the last two decades, we have expanded our business globally through a series of strategic investments. We now operate an integrated worldwide network of steel pipe manufacturing, research, finishing and service facilities with industrial operations in the Americas, Europe, Asia and Africa and a direct presence in most major oil and gas markets.

Our mission is to deliver value to our customers through product development, manufacturing excellence, and supply chain management. We seek to minimize risk for our customers and help them reduce costs, increase flexibility and improve time-to-market. Our employees around the world are committed to continuous improvement by sharing knowledge across a single global organization.

For more information on the Company, including its competitive strengths, business segments and products see our restated annual report for the year ended December 31, 2014, and for a discussion and analysis of our financial condition and results of operations see “Business overview - Operating and Financial Review and Prospects” in this half-year report.

PRINCIPAL RISKS AND UNCERTAINTIES

We face certain risks associated to our business and the industry in which we operate. We are a global steel pipe manufacturer with a strong focus on manufacturing products and related services for the oil and gas industry. Demand for our products depends primarily on the level of exploration, development and production activities of oil and gas companies which is affected by current and expected future prices of oil and natural gas. Several factors, such as the supply and demand for oil and gas, and political and global economic conditions, affect these prices. Performance may be further affected by changes in governmental policies, the impact of credit restrictions on our customers’ ability to perform their payment obligations with us, and any adverse economic, political or social developments in our major markets. Furthermore, competition in the global market for steel pipe products may cause us to lose market share and hurt our sales and our profitability may be hurt if increases in the cost of raw materials and energy cannot be offset by higher selling prices. In addition, there is an increased risk that unfairly-traded steel pipe imports in markets in which Tenaris produces and sells its products may affect Tenaris’s market share, deteriorate the pricing environment and hurt sales and profitability. A recession in the developed countries, a cooling of emerging market economies or an extended period of below-trend growth in the economies that are major consumers of steel pipe products would likely result in reduced demand of our products, adversely affecting our revenues, profitability and financial condition.

We have significant operations in various countries, including Argentina, Brazil, Canada, Colombia, Italy, Japan, Mexico, Nigeria, Romania and the United States, and we sell our products and services throughout the world. Therefore, like other companies with worldwide operations, our business and operations have been, and could in the future be, affected from time to time to varying degrees by political, economic and social developments and changes in, laws and regulations. These developments and changes may include, among others, nationalization, expropriations or forced divestiture of assets; restrictions on production, imports and exports, interruptions in the supply of essential energy inputs; exchange and/or transfer restrictions, inability or increasing difficulties to repatriate income or capital or to make contract payments; inflation; devaluation; war or other international conflicts; civil unrest and local security concerns, including high incidences of crime and violence involving drug trafficking organizations that threaten the safe operation of our facilities and operations; direct and indirect price controls; tax increases and changes in the interpretation, application or enforcement of tax laws and other retroactive tax claims or challenges; changes in laws, norms and regulations; cancellation of contract rights; and delays or denials of governmental approvals. As a global company, a portion of our business is carried out in currencies other than the U.S. dollar, which is the Company’s functional currency. As a result, we are exposed to foreign exchange rate risk, which could adversely affect our financial position and results of operations.

In 2009, Venezuela’s former President Hugo Chávez announced the nationalization of Tavsa, Matesi, Materiales Siderúrgicos S.A., or Matesi, and Complejo Siderurgico de Guayana, C.A., or Comsigua, and Venezuela formally assumed exclusive operational control over the assets of Tavsa. In 2010, Venezuela’s National Assembly declared Matesi’s assets to be of public and social interest and ordered the Executive Branch to take the necessary measures for the expropriation of such assets. Our investments in Tavsa, Matesi and Comsigua are protected under applicable bilateral investment treaties, including the bilateral investment treaty between Venezuela and the Belgian-Luxembourgish Union, and Tenaris continues to reserve all of its rights under contracts, investment treaties and Venezuelan and international law. Tenaris has consented to the jurisdiction of the International Centre for Settlement of Investment Disputes, or ICSID, in connection with the nationalization process. In August 2011 and July 2012, respectively, Tenaris and its wholly-owned subsidiary Talta - Trading e Marketing Sociedad Unipessoal Lda, or Talta, initiated arbitration proceedings against Venezuela before the ICSID seeking adequate and effective compensation for the expropriation of their investments in Matesi and Tavsa and Comsigua. However, we can give no assurance that the Venezuelan government will agree to pay a fair and adequate compensation for our interest in Tavsa, Matesi and Comsigua, or that any such compensation will be freely convertible into or exchangeable for foreign currency. For further information on the nationalization of the Venezuelan subsidiaries, see note 30 “Nationalization of Venezuelan Subsidiaries” to our restated annual report for the year ended December 31, 2014.

A key element of our business strategy is to develop and offer higher value-added products and services and to continuously identify and pursue growth-enhancing strategic opportunities. We must necessarily base any assessment of potential acquisitions, joint ventures and investments, on assumptions with respect to operations, profitability and other matters that may subsequently prove to be incorrect. Failure to successfully implement our strategy, or to integrate future acquisitions and strategic investments, or to sell acquired assets or business unrelated to our business under favorable terms and conditions, could affect our ability to grow, our competitive position and our sales and profitability.

We may be required to record a significant charge to earnings if we must reassess our goodwill or other assets as a result of changes in assumptions underlying the carrying value of certain assets, particularly as a consequence of deteriorating market conditions. At June 30, 2015 we had $1,740 million in goodwill corresponding mainly to the acquisition of Hydril, in 2007 ($920 million) and Maverick, in 2006 ($675 million). As of December 31, 2014, we recorded an impairment charge of $206 million on the value of our welded pipe assets in Colombia and Canada, reflecting the decline in oil prices, their impact on drilling activity and consequently on the demand outlook for welded pipe products in the regions served by these facilities. Additionally, as of September 30, 2014 we also recorded a $161 million impairment on the carrying value of our investment in Usiminas. This action followed a discussion with the SEC Staff after which the Company revised the carrying value of its Usiminas investment as of September 30, 2014. If our management were to determine in the future that the goodwill or other assets were impaired, particularly as a consequence of deteriorating market conditions, we would be required to recognize a non-cash charge to reduce the value of these assets, which would adversely affect our results of operations.

Potential environmental, product liability and other claims arising from the inherent risks associated with the products we sell and the services we render, including well failures, line pipe leaks, blowouts, bursts and fires, that could result in death, personal injury, property damage, environmental pollution or loss of production could create significant liabilities for us. Environmental laws and regulations may, in some cases, impose strict liability (even joint and several strict liability) rendering a person liable for damages to natural resources or threats to public health and safety without regard to negligence or fault. In addition, we are subject to a wide range of local, provincial and national laws, regulations, permit requirements and decrees relating to the protection of human health and the environment, including laws and regulations relating to hazardous materials and radioactive materials and environmental protection governing air emissions, water discharges and waste management. Laws and regulations protecting the environment have become increasingly complex and more stringent and expensive to implement in recent years. The cost of complying with such regulations is not always clearly known or determinable since some of these laws have not yet been promulgated or are under revision. These costs, along with unforeseen environmental liabilities, may increase our operating costs or negatively impact our net worth.

We conduct business in certain countries known to experience governmental corruption. Although we are committed to conducting business in a legal and ethical manner in compliance with local and international statutory requirements and standards applicable to our business, there is a risk that our employees or representatives may take actions that violate applicable laws and regulations that generally prohibit the making of improper payments to foreign government officials for the purpose of obtaining or keeping business, including laws relating to the 1997 OECD Convention on Combating Bribery of Foreign Public Officials in International Business Transactions such as the U.S. Foreign Corrupt Practices Act, or FCPA.

As a holding company, our ability to pay expenses, debt service and cash dividends depends on the results of operations and financial condition of our subsidiaries, which could be restricted by legal, contractual or other limitations, including exchange controls or transfer restrictions, and other agreements and commitments of our subsidiaries.

The Company’s controlling shareholder may be able to take actions that do not reflect the will or best interests of other shareholders.

BUSINESS OVERVIEW

Operating and Financial Review and Prospects

The following discussion and analysis should be read in conjunction with the audited restated consolidated financial statements and the related notes included in our restated annual report for the year ended December 31, 2014, and is based on, and should be read in conjunction with, the unaudited consolidated condensed interim financial statements for the six-month period ended June 30, 2015, included in this half-year report.

Certain information contained in this discussion and analysis and presented elsewhere in this half-year report, including information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks and uncertainties. See “Cautionary Statement Concerning Forward-Looking Statements” in this half-year report. In evaluating this discussion and analysis, you should specifically consider the various risk factors identified in “Principal Risks and Uncertainties”, other risk factors identified elsewhere in this half-year report and other factors that could cause results to differ materially from those expressed in such forward-looking statements.

Market Background and Outlook

Oil and gas drilling activity in North America continued to decline during the second quarter but, over the last month, the US rig count has shown signs of stabilizing at around 50% of last year’s level. The Canadian rig count is also down over 40% year on year. In most other areas of the world, oil and gas drilling activity continues to decline at a more gradual pace as companies reduce their investments, delaying projects as they adjust costs to the lower oil price environment.

Demand for OCTG products this year is being affected by the decline in drilling activity and by inventory adjustments which are ongoing in the Middle East, sub-Saharan Africa and in North America as the level of imports has declined.

We expect our revenues to decline further in the third quarter, when we will have an unusually low level of shipments of premium products. Average selling prices will be lower during the second half reflecting lower market prices and a less favorable product mix. Our margins in the third quarter will continue to be affected by low utilization of production capacity, but should improve in the fourth quarter as shipments start to recover.

Going into 2016, we expect shipments to continue to recover as customer inventory reductions come to an end and our margins will benefit from cost reduction measures and from the full impact of the current low raw material costs.

In the current difficult market conditions, we are advancing with the restructuring of our operations and remain focused on reducing our costs, strengthening our market position and enhancing our service deployment in key regions. Our expected cash flow will allow us to maintain our strong financial position.

Summary

Our sales in the first half of 2015 declined 21% compared to the first half of 2014, mainly due to lower shipments of tubular products. EBITDA declined 44% to $792 million in the first half of 2015 compared to $1,421 million in the first half of the previous year, following the decline in sales and a reduction in the Ebitda margin, from 27.1% in the first half of 2014 to 19.2% in the first half of 2015. During the first half of 2015 we had severance costs amounting to $105 million, associated to the adjustment of the workforce to current market conditions. Net income attributable to owners of the parent during the first half of 2015 was $321 million, or $0.27 per share ($0.54 per ADS), which compares with $830 million, or $0.70 per share ($1.41 per ADS), in the first half of 2014. The 62% decline in net income mainly reflects a challenging operating environment affected by lower shipments, inefficiencies associated with low utilization of production capacity and severance costs to adjust the workforce to current market conditions.

Cash flow from operations amounted to $1,426 million during the first half of 2015, including working capital reductions of $912 million. Following a dividend payment of $354 million in May 2015, and capital expenditures of $523 million during the first half of 2015, we reached a net cash position (cash and other current investments less total borrowings) of $1.8 billion at the end of June 2015.

The following table shows our net sales by business segment for the periods indicated below:

†2015 first half Tubes operating income includes severance charges of $100 million. If these charges were not included operating income would have been $569 million with a margin of 15.1%.

Net sales of tubular products and services decreased 23% to $3,759 million in the first half of 2015, compared to $4,865 million in the first half of 2014, as a result of a 20% decline in shipments following the adjustment in oil and gas drilling activity in response to the collapse in oil and gas prices and inventory adjustments taking place in the Middle East and Africa and in the United States.

Operating income from tubular products and services decreased 57% to $469 million in the first half of 2015, from $1,099 million in the first half of 2014, following the decline in sales and a reduction in operating margins affected by inefficiencies associated with low utilization of production capacity and severance costs to adjust the workforce to current market conditions, which amounted to $100 million for the segment.

Others

The following table indicates, for our Others business segment, net sales, operating income and operating income as a percentage of net sales for the periods indicated below:

Millions of U.S. dollars	For the six-month period ended June 30,
	2015			2014			Increase / (Decrease)

Net sales		363			376			(4	%)
Operating income		22			16			34	%
Operating income (% of sales)		5.9	%		4.3	%

Net sales of other products and services decreased 4% to $363 million in the first half of 2015, compared to $376 million in the first half of 2014, mainly due to lower sales of sucker rods, reflecting the decline in activity in the oil and gas business.

Operating income from other products and services increased 34%, to $22 million in the first half of 2015, compared to $16 million during the first half of 2014, mainly due to an improvement in the operating margins of the industrial equipment business in Brazil.

Selling, general and administrative expenses, or SG&A, amounted to $874 million in the first half of 2015 and $1,007 million in the first half of 2014, however, it increased as a percentage of net sales to 21.2% in the first half of 2015 compared to 19.2% in the first half of 2014 mainly due to the effect of fixed and semi fixed expenses on lower sales and the effect of $38 million in severance indemnities related to the adjustment of the workforce to current market conditions.

Financial results amounted to a loss of $10 million in the first half of 2015, compared to a gain of $43 million in the first half of 2014. Net finance income amounted to $7 million in the first half of 2015, compared to $3 million in the first half of 2014. In the first half of 2014 we had positive other financial results amounting to $39 million, mainly due to the positive impact from the Argentine peso devaluation against the U.S. dollar on our Argentine peso-denominated borrowings and liabilities.

Equity in earnings of non-consolidated companies generated a gain of $12 million in the first half of 2015, compared to a gain of $33 million in the first half of 2014. These results are mainly derived from our equity investment in Ternium (NYSE:TX).

Income tax charges amounted to $167 million in the first half of 2015, equivalent to 34.7% of income before equity in earnings of non-consolidated companies and income tax, compared to $343 million in the first half of 2014, or 29.6% of income before equity in earnings of non-consolidated companies and income tax. During the first half of 2015, our tax rate was negatively affected by the effect of certain currencies devaluation against the U.S. dollar, on the tax base used to calculate deferred taxes at subsidiaries which have the U.S. dollar as their functional currency (e.g., Argentine and Mexican peso).

Income attributable to non-controlling interests amounted to $5 million in the first half of 2015, compared to $18 million in the first half of 2014. These results are mainly attributable to NKKTubes, our Japanese subsidiary.

Net cash provided by operations during the first half of 2015 amounted to $1,426 million (including working capital reductions of $912 million), compared to $1,178 million in the first half of 2014.

Capital expenditures amounted to $523 million in the first half of 2015, compared to $412 million in the first half of 2014. The increase has to do mainly with the progress in the construction of the greenfield seamless facility in Bay City, Texas.

Following a dividend payment of $354 million in May 2015, our financial position at June 30, 2015, amounted to a net cash position (i.e., cash and other current investments less total borrowings) of $1.8 billion, compared with a net cash position of $1.3 billion at June 30, 2014.

MAIN EVENTS OF THE PERIOD

Annual General Meeting of Shareholders

On May 6, 2015, the Company’s annual general shareholders’ meeting approved all resolutions on its agenda.

Among other resolutions adopted at the meeting, the shareholders approved our previously issued audited consolidated financial statements as of and for the year ended December 31, 2014 and the annual accounts as at December 31, 2014, and acknowledged the related management and independent auditors’ reports and certifications. (Our audited restated consolidated financial statements for the year ended December 31, 2014, will be submitted to the consideration of our next annual general shareholders’ meeting to be held on May 4, 2016).

The meeting also approved the payment of a dividend for the year ended December 31, 2014, of $0.45 per share (or $0.90 per ADS), or approximately $531 million, which includes the interim dividend of $0.15 per share (or $0.30 per ADS) paid in November 2014. Tenaris paid the balance of the annual dividend in the amount of $0.30 per share ($0.60 per ADS), or approximately $354 million, in May 2015.

The annual general meeting of shareholders approved the re-election of the current members of the board of directors, each to hold office until the meeting that will be convened to decide on the 2015 accounts.

The board of directors subsequently confirmed and re-appointed Amadeo Vázquez y Vázquez, Jaime Serra Puche and Roberto Monti as members of Tenaris’s audit committee, with Mr. Vázquez y Vázquez to continue as chairman. All three members of the audit committee qualify as independent directors under the articles and applicable law.

The meeting appointed PricewaterhouseCoopers Société coopérative, Cabinet de révision agréé (member firm of PwC International Limited) as Tenaris’s independent auditors for the fiscal year ending December 31, 2015.

On May 6, 2015, the Company also held an extraordinary general meeting of shareholders, which decided to renew for a five-year period the authorization granted to its board of directors to issue shares within the limits of the authorized share capital without shareholder approval.

RELATED PARTY TRANSACTIONS

Tenaris is a party to several related party transactions, which include, among others, purchases and sales of goods (including steel pipes, flat steel products, steel bars, raw materials, gas and electricity) and services (including engineering services and related services) from or to entities controlled by San Faustin or in which San Faustin holds significant interests. Material related party transactions are subject to the review of the audit committee of the Company’s board of directors and the requirements of the Company’s articles of association and Luxembourg law. For further detail on Tenaris’s related party transactions, see Note 13 “Related party transactions” to our unaudited consolidated condensed interim financial statements included in this half-year report.

Management Certification

We confirm, to the best of our knowledge, that:

the unaudited consolidated condensed interim financial statements prepared in conformity with International Financial Reporting Standards included in this half year report, give a true and fair view of the assets, liabilities, financial position and profit or loss of Tenaris S.A. and its consolidated subsidiaries, taken as a whole; and

the interim management report included in this half year report, includes a fair review of the important events that have occurred during the six-month period ended June 30, 2015, and their impact on the unaudited consolidated condensed interim financial statements for such period, material related party transactions and a description of the principal risks and uncertainties they face.

CONSOLIDATED CONDENSED INTERIM FINANCIAL STATEMENTS

JUNE 30, 2015

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of

Tenaris S.A.

We have reviewed the accompanying consolidated condensed interim statement of financial position of Tenaris S.A. and its subsidiaries as of 30 June 2015, and the related consolidated condensed interim statements of income and of comprehensive income for each of the three-month and the six-month periods ended 30 June 2015 and 2014, and the consolidated condensed interim statements of changes in equity and of cash flows for the six-month periods ended 30 June 2015 and 2014. These consolidated condensed interim financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying consolidated condensed interim financial statements for them to be in conformity with International Accounting Standard 34 “Interim Financial Reporting” as issued by the International Accounting Standards Board and adopted by the European Union.

We previously audited in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated statement of financial position as of 31 December 2014, and the related consolidated statements of income, of comprehensive income, of changes in equity and of cash flows for the year then ended (not presented herein), and in our report dated 29 May 2015, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated condensed interim statement of financial position as of 31 December 2014, is fairly stated in all material respects in relation to the consolidated statement of financial position from which it has been derived.

The preparation of Consolidated Condensed Interim 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 as of the balance sheet dates, and the reported amounts of revenues and expenses for the reported periods. Actual results may differ from these estimates.

Material inter-company transactions, balances and unrealized gains (losses) on transactions 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 inter-company transactions are generated. These are included in the Consolidated Condensed Interim Income Statement under Other financial results.

There were no changes in valuation techniques during the period and there have been no changes in the risk management department or in any risk management policies since the year ended December 31, 2014.

Whenever necessary, certain comparative amounts have been reclassified to conform to change in presentation in current period.

None of the accounting pronouncements issued after December 31, 2014 and as of the date of these Financial Statements have a material effect on the Company’s financial condition or result of operations.

11	Contingencies, commitments and restrictions to the distribution of profits

Contingencies

This note should be read in conjunction with Note 25 to the Company’s audited Restated Consolidated Financial Statements for the year ended December 31, 2014.

Tenaris is from time to time subject to various claims, lawsuits and other legal proceedings, including customer claims, in which third parties are seeking payment for alleged damages, reimbursement for losses or indemnity. Some of these claims, lawsuits and other legal proceedings involve highly complex issues, and often these issues are subject to substantial uncertainties. Accordingly, potential liability with respect to a large portion of such claims, lawsuits and other legal proceedings cannot be estimated with certainty. Management with the assistance of legal counsel periodically reviews the status of each significant matter and assesses potential financial exposure. If a potential loss from a claim, lawsuit or proceeding is considered probable and the amount can be reasonably estimated, a provision 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 litigation and settlement strategies. The Company believes that the aggregate provisions recorded for potential losses in these financial statements are adequate based upon currently available information. However, if management’s estimates prove incorrect, current reserves could be inadequate and Tenaris could incur a charge to earnings which could have a material adverse effect on Tenaris’ results of operations, financial condition, net worth and cash flows.

Set forth below is a description of Tenaris' material ongoing legal proceedings:

Tax assessment in Italy

An Italian subsidiary of Tenaris received on December 24, 2012 a tax assessment from the Italian tax authorities related to allegedly omitted withholding tax on dividend payments made in 2007. The assessment, which was for an estimated amount of EUR282 million (approximately $316 million), comprising principal, interest and penalties, was appealed with the tax court in Milan. In February 2014, the tax court issued its decision on this tax assessment, partially reversing the assessment for 2007 and lowering the claimed amount to approximately EUR9 million (approximately $10 million), including principal, interest and penalties. On October 2, 2014, the Italian tax authorities appealed against the tax court decision on the first assessment. On June 12, 2015, the tax court accepted the defense arguments by the Tenaris subsidiary and rejected the appeal by the Italian tax authorities, thus reversing the entire 2007 assessment and recognizing that the dividend payment was exempt from withholding tax.

Tax assessment in Italy (Cont.)

On December 24, 2013, the Italian subsidiary received a second tax assessment from the Italian tax authorities related to allegedly omitted withholding tax on dividend payments made in 2008. This second assessment, based on the same arguments of the first assessment, is for an estimated amount, as of June 30, 2015, of EUR248 million (approximately $277 million), comprising principal, interest and penalties. On February 20, 2014, the assessment for 2008 was appealed with the tax court in Milan. A first hearing on this appeal was held on June 22, 2015, and a new hearing will take place on October 12, 2015.

Based on the tax court decisions on the first assessment, Tenaris believes that it is not probable that the ultimate resolution of either the first or the second tax assessment will result in a material obligation.

CSN claims relating to the January 2012 acquisition of Usiminas shares

In 2013, Confab was notified of a lawsuit filed in Brazil by Companhia Siderúrgica Nacional (CSN) and various entities affiliated with CSN against Confab and the other entities that acquired a participation in Usiminas’ control group in January 2012.

The CSN lawsuit alleges that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-along tender offer to all non-controlling holders of Usiminas ordinary shares for a price per share equal to 80% of the price per share paid in such acquisition, or BRL28.8, and seeks an order to compel the acquirers to launch an offer at that price plus interest. If so ordered, the offer would need to be made to 182,609,851 ordinary shares of Usiminas not belonging to Usiminas’ control group, and Confab would have a 17.9% share in that offer.

On September 23, 2013, the first instance court issued its decision finding in favor of Confab and the other defendants and dismissing the CSN lawsuit. The claimants appealed the court decision and the defendants filed their response to the appeal. It is currently expected that the court of appeals will issue its judgment on the appeal within 2015.

The Company is aware that on November 10, 2014, CSN filed a separate complaint with Brazil’s securities regulator Comissão de Valores Mobiliários (CVM) on the same grounds and with the same purpose as the lawsuit referred to above. The CVM proceeding is underway and the Company has not yet been served with process or requested to provide its response.

Finally, on December 11, 2014, CSN filed a claim with Brazil’s antitrust regulator Conselho Administrativo de Defesa Econômica (CADE). In its claim, CSN alleged that the antitrust clearance request related to the January 2012 acquisition, which was approved by CADE without restrictions in August 2012, contained a false and deceitful description of the acquisition aimed at frustrating the minority shareholders’ right to a tag-along tender offer, and requested that CADE investigate and reopen the antitrust review of the acquisition and suspend the Company’s voting rights in Usiminas until the review is completed. On May 6, 2015, CADE rejected CSN’s claim. CSN did not appeal the decision and on May 19, 2015, CADE finally closed the file.

Tenaris believes that all of CSN's claims and allegations are groundless and without merit, as confirmed by several opinions of Brazilian legal counsel and previous decisions by CVM, including a February 2012 decision determining that the above mentioned acquisition did not trigger any tender offer requirement, and, more recently, the first instance court decision on this matter first referred to above. Accordingly, no provision was recorded in these Consolidated Condensed Interim Financial Statements.

11	Contingencies, commitments and restrictions to the distribution of profits (Cont.)

Commitments

Set forth is a description of Tenaris’ main outstanding commitments:

A Tenaris company is a party to a contract with Nucor Corporation under which it is committed to purchase on a monthly basis a minimum volume of hot-rolled steel coils at prices that are negotiated annually by reference to prices to comparable Nucor customers. The contract became effective in May 2013 and will be in force until December 2017; provided, however, that either party may terminate the contract at any time after January 1, 2015 with 12-month prior notice. Due to the current weak pipe demand associated with the reduction in drilling activity, the Company reached a temporary agreement with Nucor to purchase steel volumes in accordance with its needs. As of June 30, 2015, the estimated aggregate contract amount through June 30, 2016, calculated at current prices, is approximately $249 million.

A Tenaris company, entered into various contracts with suppliers pursuant to which it committed to purchase goods and services for a total amount of approximately $444.7 million related to the investment plan to expand Tenaris’ U.S. operations with the construction of a state-of-the-art seamless pipe mill in Bay City, Texas. As of June 30, 2015 approximately $570 million had already been invested.

(*) Main balances included in this level correspond to Available for sale assets related to Tenaris’ interest in the nationalized Venezuelan companies. For further detail regarding Available for sale assets, see Note 30 to the Company’s audited Restated Consolidated Financial Statements for the year ended December 31, 2014.

Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (that is, as prices) or indirectly (that is, derived from prices).

Level 3 - Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs).

There were no transfers between Level 1 and 2 during the period.

The fair value of financial instruments traded in active markets is based on quoted market prices at the reporting date. A market is regarded as active if quoted prices are readily and regularly available from an exchange, dealer, broker, industry group, pricing service, or regulatory agency, and those prices represent actual and regularly occurring market transactions on an arm’s length basis. The quoted market price used for financial assets held by Tenaris is the current bid price. These instruments are included in Level 1 and comprise primarily corporate and sovereign debt securities.

The fair value of financial instruments that are not traded in an active market (such as certain debt securities, certificates of deposits with original maturity of more than three months, forward and interest rate derivative instruments) is determined by using valuation techniques which maximize the use of observable market data where available and rely as little as possible on entity specific estimates. If all significant inputs required to value an instrument are observable, the instrument is included in Level 2. Tenaris values its assets and liabilities included in this level using bid prices, interest rate curves, broker quotations, current exchange rates, forward rates and implied volatilities obtained from market contributors as of the valuation date.

If one or more of the significant inputs are not based on observable market data, the instruments are included in Level 3. Tenaris values its assets and liabilities in this level using observable market inputs and management assumptions which reflect the Company’s best estimate on how market participants would price the asset or liability at measurement date.

14	Fair Value (Cont.)

Estimation

Financial assets or liabilities classified as assets at fair value through profit or loss are measured under the framework established by the IASB accounting guidance for fair value measurements and disclosures.

The fair values of quoted investments are generally based on current bid prices. If the market for a financial asset is not active or no market is available, fair values are established using standard valuation techniques.

For the purpose of estimating the fair value of Cash and cash equivalents and Other Investments expiring in less than ninety days from the measurement date, the Company usually chooses to use the historical cost because the carrying amount of financial assets and liabilities with maturities of less than ninety days approximates to their fair value.

The fair value of all outstanding derivatives is determined using specific pricing models that include inputs that are observable in the market or can be derived from or corroborated by observable data. The fair value of forward foreign exchange contracts is calculated as the net present value of the estimated future cash flows in each currency, based on observable yield curves, converted into U.S. dollars at the spot rate of the valuation date.

Borrowings are comprised primarily of fixed rate debt and variable rate debt with a short term portion where interest has already been fixed, they are classified under other financial liabilities and measured at their carrying amount. Tenaris estimates that the fair value of its main financial liabilities is approximately 100.1% and 100.4% of its carrying amount including interests accrued as of June 30, 2015 and 2014, respectively. Tenaris estimates that a change of 100 basis points in the reference interest rates would have an estimated impact of approximately 0.4% and 0.3% in the fair value of borrowings as of June 30, 2015 and 2014, respectively. Fair values were calculated using standard valuation techniques for floating rate instruments and comparable market rates for discounting flows.
