Risks related to our business

Our financial statements indicate that we have a going concern uncertainty, which could adversely affect our ability to meet our ongoing financing needs and obtain third party financing.

We have suffered significant operating losses, working capital deficiencies and negative operating cash flow, and a significant amount of our short-term borrowings needs to be refinanced. In addition, starting in 2009, we experienced a significant decline in sales in the United States due to the anti-dumping and countervailing duties on seamless pipes made in China, which resulted in low utilization of our production capacity. Additionally, in connection with the global credit and economic crisis in the past few years, some of our customers experienced reductions in cash flows and availability of credit and increased costs of borrowing due to tightening of the credit markets, which had significant adverse effects on the their financial conditions. This may result in project modifications, delays or cancellations, general business disruptions, and delays in, or nonpayment of, amounts that are owed to us, which could have a significant adverse effect on our results of operations and cash flows. Moreover, because we depend on a limited number of customers, any decline in our major customers’ businesses could lead to a decline in purchase orders from these customers and materially and adversely affect our business, results of operations and financial condition.

We rely largely on operating cash flow and short-term borrowings for the working capital needs of our operations. As of December 31, 2012, our total bank and other borrowings amounted to $802.9 million, of which $787.0 million were short-term bank borrowings. Our substantial indebtedness could have important consequences to our investors. For example, it could:

·limit our ability to satisfy our obligations under our debt;

·increase our vulnerability to adverse general economic and industry conditions;

·require us to dedicate a substantial portion of our cash flow from operations to servicing and repaying our indebtedness, thereby reducing the availability of our cash flow to fund working capital, capital expenditures and other general corporate purposes;

·limit our flexibility in planning for or reacting to changes in our businesses and the industry in which we operate;

·place us at a competitive disadvantage compared to our competitors that have less debt;

·impair our ability to develop business opportunities or make strategic acquisitions; and

·increase the cost of additional financing.

4

In addition, our facility agreements with certain commercial banks contain various covenants. A failure to maintain the financial covenants, or a breach of any of the other restrictive covenants, would result in a default under the relevant facility agreements. If the lender accelerates the repayment of borrowings, we may not have sufficient cash or assets to repay the loans under the facility agreements. The existence of these conditions may raise the issue about our ability to continue as a going concern. We cannot assure you that our business will generate sufficient cash flow from operations in the future to service our debts and make necessary capital expenditures, in which case we may (i) seek additional financing, (ii) seek to refinance some or all of our debts or (iii) dispose of certain assets. See “—Restrictive covenants under our facility agreements and any future indebtedness may limit the manner in which we operate and an event of default under any of our facility agreements and any future indebtedness may adversely affect our operations; and our financial leverage may hinder our ability to expand and materially affect our results of operations.” and “—We and our subsidiaries have been in breach of certain financial covenants under certain loan agreements, which, if not managed carefully, may trigger events of default and accelerated payment and adversely affect our business, financial condition and results of operations.” Additionally, in 2012 and 2013 we also obtained high interest loans from non-commercial lenders. These loans typically had durations of no longer than seven days and annualized interest rates of approximately 90%. We paid interest of approximately RMB4.4 million ($0.7 million) and RMB2.7 million ($0.4 million) on these high interest loans in the year ended December 31, 2012 and the nine months ended September 30, 2013. If we are forced to place more reliance on these types of high interest loans in the future as sources of financing, our business and results of operations may be materially and adversely affected.

The existence of a going concern uncertainty could affect our ability to obtain financing from third parties or could result in increased costs of such financing. See our financial statements included in this annual report for more details. Although we believe that we will be able to renew a substantial portion of our bank borrowings and bank credit facilities when they fall due, any additional financing may not be available in the amounts we need or on terms acceptable to us, if at all. The incurrence of debt would divert cash for working capital and capital expenditures to service debt obligations and could result in operating and financial covenants that restrict our operations and our ability to pay dividends to our shareholders. We may not be able to refinance some or all of our existing facilities on commercially reasonable terms and in a timely manner. Our ability to refinance existing facilities and borrow additional funds is affected by a variety of factors, including (i) limitations imposed on us under the financing agreements that contain restrictive covenants and borrowing conditions that may limit our ability to raise additional debt, (ii) the decline in liquidity in the credit markets, (iii) prevailing interest rates, (iv) the strength of the lenders from whom we borrow, and (v) changes in the PRC government’s policies in connection with commercial loans. An event of default, any material negative change of our operation and financial conditions, an adverse action by a regulatory authority or a general deterioration in the economy that constricts the availability of credit may increase our cost of funds and make it difficult for us to renew existing credit facilities and obtain new loans. In the event that we are unable to meet our liabilities when they become due or if our creditors take legal actions against us for payment, we may have to liquidate long-term assets to repay our creditors. We may have difficulty converting our long-term assets into current assets in such a situation and may suffer material losses upon the sale of our long-term assets.

Restrictive covenants under our facility agreements and any future indebtedness may limit the manner in which we operate and an event of default under any of our facility agreements and any future indebtedness may adversely affect our operations; and our financial leverage may hinder our ability to expand and materially affect our results of operations.

Our facility agreements with certain commercial banks contain, and any future indebtedness we incur may contain, various covenants and conditions that limit our ability to, among other things:

·incur or guarantee additional debt;

·secure loans, make capital expenditures or engage in investments and acquisitions;

·enter into transactions with affiliates;

·create liens;

·announce cash dividends;

·make major investments;

·merge or consolidate with other companies, implement any divesture, reorganization, restructuring, discontinuance of business, receivership, bankruptcy, dissolution or other similar proceedings; and

·dispose of, lease, transfer or sell more than 10% of our assets.

5

As a result of these covenants, we are limited in the manner in which we conduct our business and may be unable to engage in certain business activities. Some of the facility agreements also include certain financial covenants including, but not limited to, specified financial ratios that we must comply over the term of the borrowings. In August 2011, one of our subsidiaries entered into a syndicated bank credit facility agreement with two major lead commercial banks and six other participating commercial banks that provided us with a syndicated bank credit facility of up to RMB3.5 billion, with an initial commitment of RMB2.86 billion for a term up to three years from the first drawdown date. This agreement contains financial covenants applicable to one of our major subsidiaries, including maintenance of debt to asset ratio not exceeding 72% in 2011, 71% in 2012 and 67% in 2013, minimum sales of RMB4 billion in 2011, RMB4.5 billion ($722.3 million) in 2012 and RMB5.5 billion ($882.8 million) in 2013, minimum net income of RMB80 million in 2011, RMB150 million ($24.1 million) in 2012 and RMB350 million ($56.2 million) in 2013, minimum current ratios of 170% in 2011, 180% in 2012 and 180% in 2013, and minimum quick ratios of 120% in 2011, 130% in 2012 and 130% in 2013. Additionally, we must also meet certain ratios and thresholds at the end of a one-year special observation period from July 1, 2011 to June 30, 2012. These ratios and thresholds include maximum debt to asset ratio of 70%, minimum sales of RMB4.2 billion ($674.1 million), minimum net income of RMB100 million ($16.1 million), minimum current ratio of 170% and minimum quick ratio of 120%.

A failure to maintain the financial covenants, or a breach of any of the other restrictive covenants, would result in a default under the relevant facility agreements. Upon the occurrence of any default under any of the facility agreements, the lender could elect to declare all borrowings outstanding, together with accrued and unpaid interests and fees, to be due and payable, or could require us to apply all of our available cash to repay these borrowings. If the lender accelerates the repayment of borrowings, we may not have sufficient cash or assets to repay the loans under the facility agreements. Even if we are able to obtain new financing, we may not be on commercially reasonable terms, or terms that are acceptable to us.  Our failure to comply with the financial or other covenants under our facility agreements could lead us to seek a waiver or an amendment of the covenants contained in the facility agreements, or alternative financing. Any waiver of the covenants in or amendment of the terms of our facility agreements may involve upfront fees, higher annual interest costs and other terms less favorable to us than those currently offered by the existing facilities. Additionally, we may not be able to obtain alternative financing on commercially reasonable terms or terms accepted to us, if at all.  For example, we did not meet certain ratios and thresholds set forth in the financial covenants in our syndicated bank credit facility agreement for the year ended December 31, 2011, the special observation period from July 1, 2011 to June 30, 2012 and the year ended December 31, 2012. See “—We and our subsidiaries have been in breach of certain financial covenants under certain loan agreements, which, if not managed carefully, may trigger events of default and accelerated payment and adversely affect our business, financial condition and results of operations.”

We may not be able to comply with the covenants contained in our facility agreements in the future, and if we breach the covenants, we may not be able to obtain waivers for the breaches or obtain alternative financing at commercially reasonable terms. Furthermore, defaults under our existing facility agreements may result in cross-defaults under our other loans with banks in China. Such events of default may result in a substantial amount of our debt becoming immediately due, which would have a material adverse effect on our financial condition and results of operations.  Our ability to make scheduled payments under our financing agreements and any future financing transactions and our ability to refinance our debts, if necessary, will depend, among other things, on our future operating performance. See above for a discussion on the risks regarding our ability to service our debt.

We and our subsidiaries have been in breach of certain financial covenants under certain loan agreements, which, if not managed carefully, may trigger events of default and accelerated payment and adversely affect our business, financial condition and results of operations.

In August 2011, one of our subsidiaries entered into a syndicated bank credit facility agreement with two major lead commercial banks and six other participating commercial banks that provided us with a syndicated bank credit facility of up to RMB3.5 billion, with an initial commitment of RMB2.86 billion for a term up to three years from the first drawdown date. This agreement contains financial covenants applicable to one of our major subsidiaries, including maintenance of debt to asset ratio not exceeding 72% in 2011, 71% in 2012 and 67% in 2013, minimum sales of RMB4 billion in 2011, RMB4.5 billion ($722.3 million) in 2012 and RMB5.5 billion ($882.8 million) in 2013, minimum net income of RMB80 million in 2011, RMB150 million ($24.1 million) in 2012 and RMB350 million ($56.2 million) in 2013, minimum current ratios of 170% in 2011, 180% in 2012 and 180% in 2013, and minimum quick ratios of 120% in 2011, 130% in 2012 and 130% in 2013. Additionally, we must also meet certain ratios and thresholds at the end of a one-year special observation period from July 1, 2011 to June 30, 2012. These ratios and thresholds also include maximum debt to asset ratio of 70%, minimum sales of RMB4.2 billion ($674.1 million), minimum net income of RMB100 million ($16.1 million), minimum current ratio of 170% and minimum quick ratio of 120%.

The subsidiary did not meet certain financial covenants under the syndicated loan facility agreement for the year ended December 31, 2011, the special observation period from July 1, 2011 to June 30, 2012 and the year ended December 31, 2012. In December 2012, the bank syndicate waived the past breaches of financial covenants during the observation period and agreed to continue to fulfill the terms of the syndicated loan facility. Additionally, we have informed the bank syndicate that we did not meet certain financial covenants for the year ended December 31, 2012. The bank syndicate held a review meeting and reached an agreement to waive the aforementioned breaches of financial covenants. The formal approval process within the bank syndicate is currently underway. However, the bank syndicate may not grant us a waiver for these breaches or any future breaches or noncompliance. Additionally, two of our other subsidiaries are also in breach of their financial covenants under project loans. Our lenders have not accelerated the repayment of these borrowings under the aforementioned credit facilities. Due to our breaches, we have classified our long-term loans under the syndicate loan facility and project loans from such banks into short-term loans due within one year. These two subsidiaries have entered into agreements with the lenders regarding the treatment and remedying of these breaches of financial covenants and the extension of the repayment schedules of these loans. However, if we have future breaches of financial covenants under these project loans and are unable to reach an agreement with our lenders, they may accelerate repayment of these loans and we may not be able to repay the loans, which would have a material and adverse effect on our financial condition, results of operations and business prospects. See the risk factor entitled “—Our financial statements indicate that we have a going concern uncertainty, which could adversely affect our ability to meet our ongoing financing needs and obtain third party financing.” Furthermore, accelerated payments and/or defaults under our existing facility agreements may result in cross-defaults or cross-accelerations under our other loans with banks in China, which would have a material adverse effect on our business, financial condition and results of operations.

Certain of our subsidiaries entered into bill financing arrangements and transactions which may not be and in certain cases were not in compliance with relevant PRC laws and regulations, and we cannot assure you that there will not be any legal or regulatory action taken against us which would result in material adverse effect on our business conditions and cash flows.

In the years ended December 31, 2010, 2011 and 2012 and to date in 2013, certain of our subsidiaries have used a portion of our credit facilities from certain banks as bill financing to fund a portion of our working capital requirements and business operational needs.  These transactions may not be in compliance and in certain cases were not with relevant PRC laws and regulations.

Under their terms, the bill financing facilities should be used to finance trade purchases. However, we entered into certain bill financing arrangements where the amounts of bank and commercial acceptance notes drawn down on the banks under the facilities were greater than our real expectation of purchasing needs from suppliers, which included both our subsidiaries and third parties. Moreover, on some occasions, the same purchase contracts (required for the issuance of bank acceptance notes under the bill financing facilities) were presented to two or more different banks to obtain financing. A portion of the notes we issued to our subsidiaries and third-party suppliers were then presented by the relevant suppliers to the banks for collection of an amount equal to the face value of the notes after deducting interest. Cash received from the notes presented in excess of the actual amount of purchases was then provided to us and utilized for operational purposes.

These bill financing arrangements may not be in compliance with the general principles under the PRC Negotiable Instruments Law. We have sought legal advice from our PRC legal advisor regarding these bill financing arrangements. Considering the relevant factors including, in particular, that we have settled in the past these notes when they were due, and under the assumption that we are able to settle the outstanding notes when they become due, our PRC legal advisor subsequently issued a legal opinion stating that our bill financing arrangements in the years ended December 31, 2010, 2011 and 2012 would not result in any criminal or administrative liabilities on us or our senior management or directors, and there would not be any civil liabilities. The nature of our bill financing arrangements in the year ended December 31, 2012 has remained consistent with previous years. We have also obtained written confirmations from all of the endorsing banks that they will not take any legal action against us in connection with the bank and commercial acceptance notes that have been duly settled. We have settled all of the bank and commercial acceptance notes involved in the bill financing transactions in 2010, 2011 and 2012 that have become due. We expect to settle the notes from bill financing transactions that are outstanding on the date of this annual report when they become due.  Although we have obtained the written confirmations from all of the endorsing banks that they will not take any legal action against us in connection with the bank and commercial acceptance notes that have been duly settled, the endorsing banks may legal action regarding notes that we have settled regardless due to unforeseen reasons and circumstances beyond our control.

In 2012, additionally, for purposes of raising financing from a number of commercial banks, Wuxi Seamless Oil Pipes Company Limited, or WSP China, Liaoyang Seamless Oil Pipes Co., Ltd., or Liaoyang Seamless, and Songyuan Seamless Oil Pipes Co., Ltd., or Songyuan Seamless, entered into a number of intragroup transactions, under which WSP China sold approximately RMB251 million ($40.1 million) worth of goods to Liaoyang Seamless, Liaoyang Seamless sold approximately RMB252 million ($40.3 million) of goods to Songyuan Seamless and Songyuan Seamless sold approximately RMB252 million ($40.3 million) of goods to WSP China. Official sales invoices were issued for these transactions.  However, physical delivery of the underlying goods in these transactions did not occur.  As these transactions were intragroup, they did not have an overall impact on our consolidated revenues and did not result in additional tax payable, although the PRC generally accepted accounting principles, or PRC GAAP, reports of each of these three respective individual entities would have reflected sales not supported by physical delivery of the underlying goods. These sales invoices allowed our subsidiaries to obtain additional bill financing from a number of commercial banks.  Due to the nature of these transactions, these commercial banks may declare any of our borrowings to become immediately due and payable and terminate our credit facilities so that no additional borrowings can be obtained.  If any of these borrowings become immediately due and payable, we may not have the means to repay them.

Our management has conducted an assessment, including obtaining PRC legal advice and testing the design and the effectiveness of our internal control over financial reporting as of December 31, 2012. This assessment identified a material weakness that these transactions occurred without proper approval and may not be in compliance and in certain cases were not compliant with relevant PRC laws and regulations, and therefore our internal controls have not been operating effectively. See “Item 15. Controls and Procedures — Management’s annual report on internal control over financial reporting.”  In light of the current financial environment and our capital needs, we may continue to rely on such bill financing arrangements and continue to allow these borrowings relating to increased bills payable to remain until they are repaid upon maturity. Any actions by banks or regulators against us relating to these transactions could cause a disruption to our business operations and impact future financing arrangements with banks, which may have an adverse effect on our business conditions and cash flows.  The banks may take legal action against us if we fail to settle outstanding bank and commercial acceptance notes when they become due, which may disrupt our business and impact our long-term relationships with the banks and future financing plans.

Declines in domestic and international oil and natural gas prices, or domestic and international exploration, drilling and production activities, would adversely affect our profitability.

Demand for our OCTG products depends significantly on the number of domestic and worldwide oil and gas wells drilled, completed and reworked, as well as the depth and drilling conditions of these wells. The level of such drilling activities in turn depends on the level of capital spending by major oil and gas companies. A decline in domestic and worldwide oil and gas exploration, drilling and production activities would adversely affect our results of operations. Capital spending on OCTG used for oil and natural gas exploration, drilling and production activities is driven in part by the prevailing prices for oil and natural gas and the perceived stability and sustainability of those prices. Although the prices of crude oil and natural gas rose in 2012, the global credit and economic crisis have in the past reduced worldwide demand for energy and resulted in significantly lower crude oil and natural gas prices. A substantial or extended decline in oil and natural gas prices can reduce our customers’ activities and their spending on our products. If the current global economic conditions and the availability of credit worsen or continue for an extended period, this could reduce our customers’ levels of expenditures and have a significant adverse effect on our revenue and operating results.

The reduction in cash flows being experienced by our customers resulting from declines in commodity prices, together with reduced availability of credit and increased costs of borrowing due to tightening of the credit markets, could have significant adverse effects on the financial conditions of some of our customers. This could result in project modifications, delays or cancellations, general business disruptions, and delays in, or nonpayment of, amounts that are owed to us, which could have a significant adverse effect on our results of operations and cash flows.

In addition, oil and natural gas prices are subject to significant volatility due to numerous factors beyond our control, including, but not limited to, changes in the supply and demand for oil and natural gas, market uncertainty, world events, regulatory control (including by the PRC government), political developments in petroleum producing regions and the price and availability of alternative energy sources. We cannot assure you that oil and natural gas prices will not decline further or that such prices will remain at sufficiently high levels to support levels of investment in exploration, drilling and production activities that will sustain demand for our products. Any further decline in the price of oil and natural gas, even for a short period of time, may reduce or curtail expenditures by oil and gas companies in connection with exploration, drilling and production activities, which may result in lower sales volumes and prices for our products in China and overseas and materially and adversely affect our results of operations and financial condition.

Our results of operations may be adversely affected by increases in raw material prices.

Steel is the principal raw material for our products. Cost for raw materials accounted for 73.4%, 78.3% and 77.5% of our cost of revenues in 2010, 2011 and 2012, respectively. Any increase in the price of steel could reduce our profit margin if we are unable to pass such increased costs on to our customers. From the end of 2003 to mid-2008, the price of steel increased substantially due in part to increasing demand, which significantly affected our gross margin. Since 2009, the price of steel has shown increasing volatility, although it exhibited a general upward trend through 2010 and the first half of 2011 before declining toward the end of 2011. We expect the volatility of price of steel to persist in the short to medium term. The price of steel has had, and will continue to have, a significant impact on our cost of revenues. If we are unable to manage our purchases of steel at prices acceptable to us or if the price of steel increase significantly and we are not able to pass on all or part of any such price increases to our customers, our profit margins may decrease and our results of operations would be materially and adversely affected.

Measures such as initiation of anti-dumping and anti-subsidy proceedings and imposition of anti-dumping and/or countervailing duties by governments in our overseas markets could materially and adversely affect our export sales.

Anti-dumping and anti-subsidy proceedings have been initiated by some countries in relation to steel products, resulting in anti-dumping and/or countervailing duties being imposed by those countries on steel products. Those and other similar measures could trigger trade disputes in the international steel product markets that could adversely affect our exports.

In April 2009, seven U.S. companies and the United Steelworkers Union filed a petition with the U.S. International Trade Commission, or the ITC, and the U.S. Department of Commerce, or the DOC, alleging that China-based OCTG manufacturers unfairly dumped OCTG products in the U.S. market and that Chinese producers were benefitting from massive government subsidies. WSP China was named as one of the major exporters of OCTG products from China. In June 2009, we were included as one of the mandatory respondent companies to the United States government’s countervailing duty investigation. On September 8, 2009, a preliminary determination was issued with a countervailing duty rate of 24.92% assigned to WSP China. On December 7, 2009, the DOC published its final determination in the countervailing duties investigation with a rate of 14.61% assigned to WSP China. The rate was subsequently changed to 14.95% in January 2010 due to certain ministerial errors made by the DOC. We were not selected as a mandatory respondent to the anti-dumping investigation and participated in this case as a separate rate respondent. In November 2009, we received a preliminary dumping rate of 36.53%, which was based on the average dumping rates of other OCTG producers that were selected as mandatory respondents. In December 2009, this rate was amended to 96.51% due to certain ministerial errors made by the DOC. On April 9, 2010, the DOC announced its final determination in the anti-dumping investigation with a rate of 29.94% assigned to WSP China. In May 2010, the ITC made a final ruling which requires all Chinese exports of OCTG products to the United States, including WSP China’s products, be subject up to approximately 32.07% of anti-dumping duties and 14.95% of countervailing duties. The anti-dumping and countervailing duties are applied to all Chinese exports of OCTG products to the United States starting from the date of the DOC’s preliminary determinations. WSP China has not exported OCTG products to the United States after the date of the DOC’s preliminary determinations. The anti-dumping and countervailing duties will apply to us if WSP China exports OCTG products to the United States in the future and we are not subject to any other penalties or fines. In 2010, 2011 and 2012, products sold to the United States by our subsidiaries accounted for 9.7%, 6.3% and 9.3% of our net revenues, respectively. The decrease in export revenue of products sold to the United States as a percentage of our net revenues mainly was attributable to the effect of anti-dumping and countervailing duties on the subject goods. As a result of the proceedings, our sales in the U.S. suffered and our results of operations have been materially and adversely affected.

Additionally, in 2012, we have identified an immaterial amount of goods originating from China that were incorrectly imported to the United States. We are presently repatriating the goods. We are unable to estimate the likelihood that legal liability will arise as a result of the incorrect importation of these goods, including any duties that may be imposed by regulators, or the amount of liability that we would incur should any legal proceedings take place.

There may be similar actions taken in the future in other countries against PRC-made seamless OCTG products. Any actions filed against us with respect to the products we sell, even without merit, may divert significant company resources and management attention, have an adverse impact on the prices and sales of our products in the relevant countries and adversely affect our business prospects and results of operations. If any decision is entered against us in such an action, we may be subject to additional tariff liabilities and our overseas sales may be materially and adversely affected. Additionally, in July 2013, nine US manufacturers sought anti-dumping and countervailing duty investigations on OCTG products from nine countries, including Thailand. In August 2013, the ITC announced that it had found reasonable grounds to pursue an anti-dumping case against the nine countries and that the DOC was investigating the matter.  If anti-dumping duties are imposed on Thailand, our business in Thailand and the operations of WSP Pipe Company Limited, or WSP Pipe, may be significantly and adversely affected.

We depend on a limited number of customers, and any loss of these customers could materially and adversely affect our revenue and profitability.

Our customers include oil and gas companies in China and abroad. Aggregate sales attributable to our five largest customers represented approximately 46.5%, 69.5% and 63.8% of our net revenues for the years ended December 31, 2010, 2011 and 2012, respectively. We cannot assure you that we will be able to maintain or improve our relationships with these customers, or that we will be able to continue to supply products to these customers at current levels or at all. In addition, our business is affected by competition in the oil and gas industry, and any decline in our major customers’ businesses in these markets could lead to a decline in purchase orders from these customers. If any of our key customers were to substantially reduce the size or amount of the orders they place with us or were to terminate their business relationship with us entirely, we cannot assure you that we would be able to obtain orders from other customers to replace any such lost sales on comparable terms or at all. If any of these relationships were to be so altered and we were unable to obtain replacement orders, our business, results of operations and financial condition would be materially and adversely affected.

Our sales contracts typically have a term of less than six months and, as a result, customers may reduce their orders or terminate their relationships with us almost immediately.

Sales of our products are typically conducted through sales contracts with a term of less than six months. As a result, our customers may choose to terminate their relationship with us after completion of the shipment or expiration of the contract, as the case may be. Our customers are also not obligated to continue placing orders with us at historical levels or at all. If any of our customers, particularly our key customers, were to materially reduce their orders with us or were to terminate entirely their business relationship with us with short notice, we might not have sufficient time to locate alternative customers and our business and results of operations could be materially and adversely affected.

We cannot assure you that our products will pass periodic inspection by the American Petroleum Institute or the qualification processes of potential customers, and any failure by us to pass such inspection or qualifications would adversely affect our business prospects and results of operations.

We have obtained certificates from the American Petroleum Institute, or API, to use the official API monogram on our products to demonstrate that our products meet API standards. These certificates are subject to periodic inspections by API. Furthermore, our growth strategies include increasing our sales in the PRC domestic market, as well as expanding into international markets such as North America, South America, the Middle East, Asia, Africa and Russia. It is standard industry practice that an OCTG manufacturer must first pass a qualification process to become an approved supplier of an oil and gas company before providing OCTG products to that company. We cannot assure you that we will be able to obtain the necessary certifications from API or approvals for new products from our existing customers or approvals from any new customers. Even if we can ultimately secure such approvals or certifications, we cannot assure you that such certifications and approvals can be obtained in a timely manner or can be maintained. If we fail to become an approved supplier of our potential customers, or if we are unable to obtain or maintain such approval in a timely manner, we may not be able to execute our expansion plans and our business prospects and results of operations may be materially and adversely affected.

If we are unable to compete effectively in the OCTG industry, our revenues may decrease and losses may increase.

We face intense competition in the domestic and international markets in which we operate. Domestically, we face competition from a number of manufacturers that produce OCTG that are similar to ours. Our major domestic competitors include Tianjin Pipe (Group) Corporation, Shanghai Baosteel Group Corporation and Pangang Group Chengdu Iron & Steel Co., Ltd., which are mostly state-owned enterprises. We also face competition from international manufacturers, such as JFE Steel Corporation in Japan, US Steel in the United States, Tenaris in Argentina, Vallourec & Mannesmann Tubes in France, TMK in Russia and Sumitomo in Japan. Our major competitors may have longer operating history, larger customer base, stronger customer relationships, greater brand or name recognition and greater financial, technical, marketing and public relations resources than we do. Some of our competitors may also be better positioned to develop superior product features and technological innovations and be able to better adapt to market trends than we are.

10

Our ability to compete depends on, among other things, high product quality, short lead-time, timely delivery, competitive pricing, wide range of product offerings and superior customer service and support. Increased competition may require us to reduce our prices or increase our costs and may have a material adverse effect on our financial condition and results of operations. Any decrease in the quality of our products or the level of our service to our customers or any occurrence of a price war among our competitors and us may adversely affect our business and results of operations. If we are unable to remain competitive, we may not be able to increase or even maintain our current share of the OCTG market in China or overseas.

We cannot assure you that we will be successful in implementing our future expansion plans, in particular our plans for international expansion, or in managing our growth.

Historically, we have expanded our production capacity and developed our overseas sales as part of our growth strategy. For example, as a part of our international expansion strategy, in April 2008, we established our wholly-owned subsidiary, Houston OCTG Group, Inc., or Houston OCTG, in Houston, Texas. In April 2009, WSP China established Chaoyang Seamless Oil Steel Casting Pipes Co., Ltd., or Chaoyang Seamless, in Chaoyang, Liaoning Province, China. In February 2010, we acquired WSP Pipe, a company in the Thai-Chinese Rayong Industrial Zone, Thailand from Mr. Longhua Piao, our chairman and chief executive officer. In February 2010, Bazhou Seamless Oil Pipes Co., Ltd., or Bazhou Seamless, established a wholly-owned subsidiary, Kuitun Seamless Special Steel Company Co., Ltd. or Kuitun Seamless, in Kuitun, Xinjiang Autonomous Region, China. Although we disposed of Kuitun Seamless and Chaoyang Seamless in 2011 and 2012, respectively, we may expand through organic growth and selective acquisitions in the future. Furthermore, we may continue to be exposed to liabilities of a disposal entity after its disposal.  In January 2012, we entered into an agreement with a third party to transfer our entire 51% equity interest in Chaoyang Seamless for nominal cash consideration. The disposal transaction was completed in January 2012. As part of this agreement, we waived the payment of RMB39.4 million ($6.3 million) owed by Chaoyang Seamless to WSP China. In October 2013, our board of directors approved the waiver of the payment of RMB27.0 million ($4.3 million) owed by Chaoyang Seamless to Bazhou Seamless and RMB78.5 million ($12.6 million) owed by Chaoyang Seamless to Liaoyang Seamless. In connection with this waiver, we recorded bad debt expenses of approximately RMB105.5 million ($16.9 million) reflected in our results of operations for the first half of 2013. Additionally, in November 2012, we sold production facilities held by Houston OCTG to a third party for approximately $43.0 million, and incurred a loss on disposal of approximately $5.1 million in the second half of 2012 related to the sale of these assets. Our future growth will depend on a number of factors, including but not limited to, our ability to manage expansion and overseas operations, obtain any required financing, achieve operational efficiency, and secure sufficient access to raw materials. Some of these factors are beyond our control. As a result, we may not be able to successfully manage our growth, expand our operations or achieve a satisfactory return on our investments in the expansion of our production capacity and international expansion, which could have a material adverse effect on our business, financial condition and results of operations. Additionally, we may incur further losses from any future dispositions of the equity or assets of our subsidiaries or additional types of restructuring, which will materially and adversely affect our results of operation.

In addition, we may need to increase the number of our employees and enhance our operational and financial systems to manage the increased complexity and the expanded geographical coverage of our operations associated with our growth. We cannot assure you that we will be able to attract and retain qualified management staff and employees or that our current operational and financial systems and controls will be adequate to accommodate future growth. This could have a material adverse effect on our business, financial condition and results of operations.

We face risks associated with the marketing, distribution and sale of our products internationally, and if we are unable to manage these risks effectively, they could impair our ability to expand our business overseas.

We have focused on international expansion in certain mature OCTG markets. In order to succeed, we need to take market share away from the existing suppliers of seamless OCTG in these markets. We cannot assure you that we will be able to do so in these competitive markets.

Moreover, our plans for international expansion may be hindered by the following:

·cultural differences and other difficulties in staffing and managing overseas operations;

·inherent difficulties and delays in contract enforcement and collection of receivables through the use of foreign legal systems;

·volatility in currency exchange rates;

·the risk that foreign countries may impose withholding taxes (or otherwise tax our foreign income or place restrictions on repatriation of profit);

·the risk of barriers, such as anti-dumping and other tariffs or other restrictions being imposed on foreign trade;

·changes in the political, regulatory, or economic conditions in a foreign country or region; and

·the burden of complying with foreign laws and regulations.

11

If we are unable to manage these risks effectively, our ability to conduct or expand our business overseas would be impaired, which may in turn materially and adversely affect our business, financial condition, results of operations and prospects.

Our business depends on our ability to attract and retain members of our senior management team and other key personnel.

Our future success is dependent on the efforts, performance and abilities of key members of our management team, particularly Mr. Longhua Piao, our chairman and chief executive officer. Mr. Piao founded our company and has extensive industry experience. We do not maintain key person insurance on any of our management personnel. As the OCTG industry in China becomes more competitive, we expect the competition for management and other skilled personnel to intensify. Failure to attract and retain qualified employees or the loss of any member of our senior management may result in a loss of organizational focus, poor operating execution or an inability to identify and execute potential strategic initiatives such as overseas expansion and new product offerings. This could, in turn, materially and adversely affect our business, financial condition and results of operations.

Our business relies on our ability to retain and attract experienced sales staff and our ability to maintain and expand our existing sales networks both domestically and overseas.

Our experienced sales staff constitutes an essential part of our business. In the domestic PRC market, our sales staff possesses strong technical backgrounds in the OCTG industry, which enable them to provide and deliver on-site technical support to our customers. We rely on our four sales offices located in the Daqing, Changqing, Xinjiang and Sichuan oilfields to directly sell our products to the major oilfields in China. In addition to providing on-site services to our customers throughout the sales process and after-sales support, our sales staff also helps us maintain good relationships with our customers. Internationally, we sell our products through our distributors and sales agents. The loss of services of any of our experienced sales staff without timely replacement, the inability to attract and retain sales personnel, or the loss of any of our major distributors or sales agents may have an adverse effect on our business. If we are unable to maintain our existing sales network, our operations may be materially and adversely affected.

We depend on a limited number of suppliers for a majority of our raw material requirements, and interruption of raw material delivery could prevent us from delivering our products in a timely manner to our customers in the required quantities, and in turn result in order cancellations, decreased revenue and loss of market share.

Our operations depend on our ability to obtain adequate and quality supplies of our primary raw materials, namely, round steel billets and green pipes, in a timely manner. If our suppliers fail to meet our quality standards or our quantity demands, our production and sales volume and our results of operation may be adversely affected. We made an upstream acquisition of Tuoketuo County Mengfeng Special Steel Co., Ltd., or Mengfeng, from Hebei Bishi Industry Group Co., Ltd., or Hebei Bishi, in July 2008 with the aim of stabilizing the supply, quality and cost of our raw materials. However, we stopped production at Mengfeng since the second half of 2011 as we are currently able to obtain raw materials at lower costs. As such, we will continue to rely on major suppliers to supply our primary raw materials to us. See “Item 4. Information on the Company—B. Business Overview—Manufacturing—Suppliers of raw materials.” We cannot guarantee that our long-term arrangements with these suppliers will provide us with a reliable supply of raw materials. If there is any supply shortage, we may be unable to deliver our products in a timely manner to our customers in the required quantities, which in turn could result in order cancellations, decreased revenue and loss of market share.

Significant product liability claims made against us, regardless of their success, could harm our business reputation, results of operations and financial condition.

Our OCTG products are sold primarily for use in oil and gas exploration, drilling and extraction activities. These activities are subject to inherent risks, including well failures, line pipe leaks and fires that could result in death, personal injury, property damage, pollution or loss of production, all of which could result in liability claims being made against us. We typically offer warranties on our products for a period of up to one year. During the warranty period, faulty products will be repaired or replaced by us, or returned to us. Actual defects or allegations of defects in our products may give rise to claims against us for losses and expose us to claims for damages. For instance, we are subject to multiple lawsuits alleging defective casing pipes used in oil and gas well operations the United States. See “—We are subject to litigation proceedings brought by third-parties. If any of the proceedings against us is successful, it may have an adverse effect on our financial condition and operating results.” and “Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Legal proceedings” for further information about the lawsuits. Any such claim, regardless of merit, could cause us to incur significant costs, divert our management’s attention, harm our business reputation or cause significant disruption to our operations. Furthermore, we can provide no assurance that we will be able to successfully defend against such claims. We do not have any product liability insurance covering our products sold outside of North America, and limited product liability insurance for most of our products sold inside North America. If any such claims were successful, we could be subject to substantial liabilities, which could materially and adversely affect our results of operations and our financial condition.

We may be unable to prevent possible resales or transfers of our products to countries, governments, entities, or persons targeted by United States economic sanctions, especially when we sell our products to distributors over which we have limited control.

The U.S. Department of the Treasury’s Office of Foreign Assets Control, or OFAC, administers certain laws and regulations, or U.S. Economic Sanctions Laws, that impose restrictions upon U.S. persons and, in some instances, foreign entities owned or controlled by U.S. persons, with respect to activities or transactions with certain countries, including the Western Balkans, Belarus, Burma (Myanmar), Cote d’Ivoire (Ivory Coast), Cuba, Democratic Republic of the Congo, Iran, Iraq, Lebanon, Liberia (former Taylor regime), Libya, North Korea, Somalia, Sudan, Syria and Zimbabwe, and governments, entities and individuals that are the subject of U.S. Economic Sanctions Laws, or Sanctions Targets. U.S. persons are also generally prohibited from facilitating such activities or transactions. We believe that U.S. Economic Sanctions Laws under their current terms are not applicable to our activities, however, we have nonetheless decided to adopt commercially reasonable measures to prevent any sales of our products to Sanctions Targets. If we become subject to U.S. Economic Sanctions Laws, a violation of these laws and regulations could subject us to fines, penalties and other sanctions. In the three years ended December 31, 2012, we did not have any direct sales to Sanctions Targets. However, we sell our products in international markets primarily through independent non-U.S. distributors who are responsible for interacting with the end customers of our products. We have limited control over these independent non-U.S. distributors, and these distributors may breach their covenant to us not to resell our products to Sanctions Targets. In addition, we do not always know the end customers to whom our distributors resell our products. We are aware of an insignificant amount of resales of our products by two non-U.S. and non-affiliated distributor customers to Sudan, a Sanctions Target, during the three years ended December 31, 2012. See “Item 5. Operating and Financial Review and Prospects—A. Operating Results—Internal control over distribution of our products.” Although we have adopted a written policy to prevent future direct or indirect sales to Sanctions Targets and have begun to implement internal control mechanisms to enforce such policy when possible, we cannot assure you that our measures will be able to prevent future sales or resales of our products, directly or indirectly, to Sanctions Targets.

If our products are sold or re-sold, directly or indirectly, to Sanctions Targets, we may fail to comply with U.S. Economic Sanctions Laws and we may be subject to civil or criminal penalties and other remedial measures, which could have an adverse impact on our business, results of operations, financial conditions, liquidity and reputation. Additionally, we act as suppliers to leading Chinese oil companies, such as China National Petroleum Corporation, or CNPC, and China Petroleum & Chemical Corporation, or Sinopec. These companies currently and have in the past had business transactions and relationships with Sanctions Targets. As a result of these transactions and relationships with U.S.-designated state sponsors of terrorism, CNPC and Sinopec have received negative publicity and been the target of divestment or similar initiatives by state and municipal governments, universities and other investors. As a supplier to CNPC, Sinopec and other companies with relations to Sanctions Targets, we have no control over their business or operations. We do not believe that our products sold to these companies have been used outside of China. However, our relationships with such companies may nevertheless harm our reputation. Some of our U.S. investors may be required to sell their interests in our company under the laws of certain U.S. states or under internal investment policies or may decide for reputational reasons to sell such interests, and some U.S. institutional investors may forego the purchase of our ADSs, all of which could materially and adversely affect the value of our ADSs and your investment in us.

If we are unable to continue developing our production technology or adopt new production technology, our business and prospects may be harmed.

The OCTG industry is competitive and the production technology underlying the industry is evolving. As customers’ needs, related technologies and market trends are subject to change, we cannot assure you that we will be able to correctly predict the trends in a timely manner, develop or adopt competitive technology on a timely basis, or respond effectively to competitive industry conditions and changing customer demands.

Responding and adapting to technological developments and changes in the OCTG industry and the integration of new technologies or industry standards may require substantial investment of resources, time and capital. Even if we implement such measures, there can be no assurance that we will succeed in adequately responding and adapting to such technological and industry changes. In the event that we are unable to respond successfully to technological and industry changes, our business, results of operations and competitiveness may be materially and adversely affected.

Failure to protect our intellectual property rights may materially and adversely affect our competitive position and operations, and we may be exposed to infringement or misappropriation claims by third parties.

Our success is in part attributable to the technologies, know-how and other intellectual properties that we have developed or acquired. See “Item 4. Information on the Company—B. Business Overview—Intellectual property rights” for information relating to our patents and trademarks. Although we rely upon a combination of trade secrets, confidentiality policies, non-disclosure and other contractual arrangements, and patent and trademark laws to protect our intellectual property rights, there can be no assurance that the steps we have taken to protect our intellectual property rights are adequate to prevent or deter infringement or other misappropriation of our intellectual property. We may not be able to detect unauthorized uses or take appropriate and timely steps to enforce our intellectual property rights. Any significant infringement of our proprietary technologies and processes or our intellectual property rights could weaken our competitive position and have an adverse effect on our operations. To protect our intellectual property rights, we may have to commence legal proceedings against any misappropriation or infringement. However, there can be no assurance that we will prevail in such proceedings. Furthermore, as we only hold PRC patents, if third parties manufacture and sell products using our technology outside of China in competition against us, we would not have a legal cause of action against them.

Furthermore, we may be subject to litigation involving claims of patent infringement or the violation of other intellectual property rights of third parties. The defense of intellectual property suits, patent opposition proceedings and related legal and administrative proceedings can be both costly and time-consuming and may significantly divert the efforts and resources of our technical and management personnel. An adverse determination in any such litigation or proceedings to which we may become a party could subject us to significant liability to third parties, require us to seek licenses from third parties, to pay ongoing royalties, or to redesign our products or subject us to injunctions prohibiting the manufacture and sale of our products or the use of our technologies, which could materially and adversely affect our business, financial condition or results of operations. Protracted litigation could also result in our customers or potential customers deferring or limiting their purchase or use of our products until resolution of such litigation, which could adversely affect our business.

Failure to maintain an effective quality control system at our manufacturing facilities could have a material adverse effect on our business and operations.

The performance, quality and safety of our products are critical to the success of our business. These factors depend significantly on the effectiveness of our quality control systems, which in turn depend on a number of factors, including the design of our quality control systems, our quality-training program, and our ability to ensure that our employees adhere to the quality control policies and guidelines. Any significant failure or deterioration of our quality control systems could have a material adverse effect on our business reputation, results of operations and financial condition.

If disruptions in our transportation network occur or our shipping costs substantially increase, we may be unable to deliver our products in a timely manner and our cost of revenues could increase.

We are highly dependent upon transportation systems, including train, truck and ocean shipping, to deliver our products. The transportation network is potentially exposed to disruption from a variety of causes, including labor disputes or port strikes, acts of war or terrorism and natural disasters. If our delivery times or our shipping costs increase unexpectedly for any reasons, our revenues and results of operation could be materially and adversely affected.

14

Our growth strategies require significant capital investments and may require us to seek external financing, which may not be available on terms favorable to us.

Our business operations and growth strategies require substantial capital investments, the availability of which depends on our ability to generate cash flow from operations, borrow funds on satisfactory terms and raise funds in the capital markets. Our ability to arrange for financing to support our capital expenditures and the cost of such financing are dependent on numerous factors, including general economic and capital markets conditions, interest rates and credit availability from banks or other lenders, many of which are beyond our control. In addition, increases in interest rates or failure to obtain external financing on terms favorable to us will affect our financing costs and our results of operations. We may not be able to obtain financing in amounts or on terms acceptable to us, if at all, especially in the current global credit and economic crisis, which may have an adverse effect on our operating results and financial condition.

We may not be successful in our future acquisitions and investments.

If we are presented with appropriate opportunities, we may acquire additional businesses or assets as part of our growth strategy. Future acquisitions, investments and joint ventures may expose us to potential risks, and the success of our acquisitions, investments and joint ventures depend on a number of factors, including:

·our ability to identify suitable opportunities for acquisitions, investments or joint ventures;

·whether we are able to reach an acquisition, investment or joint venture agreement on terms that are satisfactory to us;

·the extent to which we are able to exercise control over the acquired company or business;

·the economic, business or other strategic objectives and goals of the acquired company or business compared to those of our company;

·the diversion of management attention and resources from our existing business;

·our ability to finance the acquisition, investment or joint venture; and

·our ability to integrate successfully the acquired company or business.

If we fail to make acquisitions or investments or form joint ventures that are strategically important to us, our growth and business prospects may be limited. If we encounter difficulties in integrating the business we acquired, our financial condition and results of operations may be materially and adversely affected.

If we fail to establish or maintain an effective system of internal controls, we may be unable to accurately report our financial results or prevent fraud, and investor confidence and the market price of our ADSs may be adversely impacted.

We are subject to reporting obligations under the U.S. securities law. The Securities and Exchange Commission, or the SEC, as required by Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, has adopted rules requiring every public company to include a management report on such company’s internal control over financial reporting in its annual report, which must also contain management’s assessment of the effectiveness of the company’s internal control over financial reporting. Additionally, Section 404 of the Sarbanes-Oxley Act also requires an independent registered public accounting firm to attest to the effectiveness of the company’s internal control over financial reporting. As a non-accelerated filer under Rule 12b-2 of the Securities Exchange Act of 1934, we are exempt from the auditor attestation requirement. However, if we become an accelerated filer or a large accelerated filer, we will once again be subject to this requirement.

In connection with the preparation of this annual report on Form 20-F, we carried out an evaluation of the effectiveness of our internal control over financial reporting. Based on this evaluation, our chief executive officer and chief financial officer concluded that our internal control over financial reporting was not effective due to material weaknesses, as defined by Auditing Standard 5, “An Audit of Internal Control Over Financial Reporting That Is Integrated with An Audit of Financial Statements.” See “Item 15. Control and Procedures.” The material weaknesses identified were:

15

·inadequate procedures for approving related party transactions, including lack of information provided to the audit committee for approval before the transactions occurred and certain related party transactions were reported to the board of directors only after they had occurred;

·due to the need to obtain bank financing, bill financing transactions and increased bills payable in intragroup transactions occurred without following proper approval and other procedures and, such transactions may not be in compliance with relevant PRC laws and regulations;

·inadequate logistical controls and procedures to ensure accurate shipment of goods; and

·insufficient skilled resources available for the purposes of financial reporting and internal audit.

We have designed certain control measures for proper implementation to address these material weaknesses. However, if we fail to maintain effective internal control over financial reporting in the future, we may not be able to conclude that we have effective internal control over financial reporting at a reasonable assurance level. This could in turn result in the loss of investor confidence in the reliability of our financial statements and negatively impact the trading price of our ADSs. Furthermore, we have incurred and anticipate that we will continue to incur considerable costs and use significant management time and other resources in an effort to comply with Section 404 and other requirements of the Sarbanes-Oxley Act.

We may be required to strictly perform under a long-term supply agreement to purchase iron ore pellets, which could materially and adversely affect our financial condition and results of operations.

In November 2009, we entered into a five-year supply agreement with an iron ore supplier in Brazil to purchase iron ore pellets. Under this agreement, we have committed to purchase a minimum amount of 300,000 tonnes of iron ore pellets to be delivered by separate shipments on a yearly basis from 2010 through 2014. However, the contractual terms of this supply agreement were not strictly performed by us and the supplier in 2010 and 2011. We and the supplier adopted a more flexible approach regarding the performance of the agreement in 2010. When we could not agree on the pricing terms of the iron ore pellets for one shipment, we agreed that the tonnage to be delivered by the shipment is deemed to be cancelled. As a result, we purchased less than 300,000 tonnes of iron ore pellets in 2010 and none in 2011, primarily due to our internal lack of iron ore pellet requirements and low market demand for sales of iron ore pellets. In 2012, although we did not purchase any iron ore pellets, we received commissions from our supplier for finding a third-party buyer for 334,117 tonnes of iron ore pellets. Nonetheless, if the supplier chooses to enforce our obligations strictly in accordance with the contractual terms under this supply agreement in the future, absent any express modification of the terms, we may be obliged to comply with our purchase obligations under this supply agreement. We may not be able to perform strictly in accordance with the terms under the agreements or enter into a satisfactory arrangement with this supplier. If we encounter problems with this supplier, we may expend additional resources in resolving disputes that may arise under this agreement.

We have previously resold some of the iron ore pellets that we purchased under the supply agreement, as in past years the prices for iron ore pellets imported under multi-year supply agreements have generally been lower than the prices on the spot market. However, if in the future we are not able to resell iron ore pellets that we purchase in excess of the demand of our steel billet manufacturing subsidiaries or generate sufficient profit from the resale of the iron ore pellets, we may overstock our inventory of iron ore pellets or be unable to recover our costs of purchasing the iron ore pellets. If the price of iron pellets rapidly declines and we are forced to provide an impairment charge on our inventory of iron ore pellets, or if we are forced to sell our stock at a reduced price to improve the aging of our inventory, our results of operations would be materially and adversely affected.

Our ability to distribute future dividends will be subject to various factors, some of which are beyond our control, and we may not be able to fulfill our dividend policy in the future.

In March 2009, we declared a cash dividend in the amount of $0.15 per ordinary share and a one-time special cash dividend in the amount of $0.225 per ordinary share out of our annual profits for the years ended December 31, 2007 and 2008. Our ability to distribute future dividends will be subject to various factors including, but not limited to, available cash and distributable reserves, investment requirements, and cash flow and working capital requirements, as well as the withholding tax obligations for dividend distribution under the PRC tax law. These factors depend on other factors that are beyond our control, including a possible economic downturn and delays in the payments made by customers. If we encounter any of these problems or others, we may not be able to declare and pay dividends in the future as currently planned.

16

We are not required to pay dividends. Our shareholders or ADS holders also do not have contractual or other rights to require us to pay dividends. Our board may decide at any time, in its discretion, to change the amount of dividends under the dividend policy, change or revoke our dividend policy, or discontinue any payment of dividends.

Our ability to make distributions or other payments to our shareholders depends primarily on payments from WSP China, whose ability to make such payments is subject to PRC regulations. Under PRC laws and accounting rules, dividends may be paid only out of distributable profits. Distributable profits with respect to WSP China refers to its after-tax profits as determined under PRC accounting standards, less any recovery of accumulated losses and allocations to statutory funds that it is required to make. For example, it is required to allocate 10% of its after-tax profit to statutory reserves until such reserves reach 50% of WSP China’s registered capital. Allocations to these statutory reserves and funds can only be used for specific purposes and are not transferable to us in the form of loans, advances or cash dividends. As a result, WSP China may not be able to pay dividends to us in any given year if it does not have distributable profits as determined under PRC accounting standards, even if we have profits for the relevant year as determined under U.S. GAAP. Accordingly, if we do not receive dividend distributions from WSP China, our liquidity, financial condition and ability to make dividend distributions will be materially and adversely affected.

Further, our dividend policy, to the extent implemented, will significantly restrict our cash reserves and may adversely affect our ability to fund unexpected capital expenditures. We may be required to borrow money or raise capital by issuing equity securities, which we may not be able to do so on attractive terms or at all. If we are unable to fulfill our dividend policy, or pay dividends at levels anticipated by investors, the market price of our ADSs may be negatively affected and the value of your investment may be reduced.

Our business is substantially dependent on the continuing devotion of our chairman and chief executive officer, and our business may be materially and adversely affected if we lose his service.

Mr. Longhua Piao, our chairman and chief executive officer, is a director and controlling shareholder of several private companies, including Eastar Industries, Inc., Expert Master Holdings Limited, or EMH, Lianyungang Eastar Photonics Technologies Co., Ltd., Regalia Investments Holdings Ltd., WSP Pipe LLC, Wuxi Huayi Investment Company Limited, Wuxi Longhua Steel Pipes Company Limited, or Wuxi Longhua, and Cambodian WS Mining Industry Holding Ltd. The changing business environment may demand more of Mr. Piao’s time outside of our company. Mr. Piao may not be able to devote substantially all of his time to our business given his duties to other companies. In addition, although none of these companies currently engage in the production and sale of OCTG products, they may enter into such business in the future. See “Item 6. Directors, Senior Management and Employees—C. Board Practices—Code of business conduct and ethics” for more details on our code of business conduct and ethics with respect to conflict of interests. If Mr. Piao is not able to devote a substantial amount of his time to our business, or if any dispute arises between Mr. Piao and us, we may not be able to find a suitable replacement in a timely manner or at all, and our business may be adversely and materially affected.

Control or significant influence by our existing shareholders may limit your ability to affect the outcome of decisions requiring the approval of shareholders.

EMH owns approximately 50.9% of our issued share capital as of the date of this annual report. Mr. Piao, our chairman and chief executive officer, is the sole shareholder of EMH, and has control over our business, including matters relating to our management and policies and certain matters requiring the approval of our shareholders, such as election of directors, approval of significant corporate transactions and the timing and distribution of dividends. Furthermore, our articles of association contain a quorum requirement of at least a majority of our total outstanding shares present in person or by proxy. EMH, with an aggregate shareholding sufficient to constitute a quorum, could approve by itself actions that require a majority vote at shareholder meetings, which may not be in the best interest of our other shareholders. Furthermore, UMW China Ventures (L) Ltd., or UMW China Ventures, which beneficially owns approximately 22.5% of our issued share capital as of the date of this annual report will have significant influence over our business. UMW China Ventures is a wholly-owned subsidiary of UMW Holdings Berhad, or UMW. Our vice chairman, Badrul Feisal bin Abdul Rahim, was nominated by UMW. To the extent the interests of EMH or UMW conflict with the interests of other shareholders, the interests of other shareholders may be disadvantaged and harmed. Moreover, we have in the past entered into related party transactions with affiliates of EMH and UMW, and we expect to continue to enter into related party transactions, subject to our audit committee’s review and approval, if applicable.

We have limited insurance coverage in China.

The insurance industry in China is still at a relatively early stage of development. We have determined that balancing the risks of disruption or liability from our business, or the loss or damage to our property, including our facilities, equipment and office furniture, the cost of insuring for these risks on the one hand, and the difficulties associated with acquiring such insurance on commercially reasonable terms on the other hand, makes it impractical for us to have such insurance. As a result, we only maintain property insurance with respect to our operations that covers general property, plant and equipment, and shipping and transportation.

We do not have any product liability insurance covering our products, except for limited product liability insurance covering our products sold in North America by Houston OCTG. A large number of our product liability insurance policies for products sold by Houston OCTG have reached their maximum payouts. We do not maintain business interruption or key-man insurance in China. Consequently, any uninsured occurrence of loss or damage to property, litigation or business disruption may result in our incurring substantial costs and the diversion of resources, which could have an adverse effect on our operating results. The occurrence of certain incidents including fire, severe weather, earthquake, war, flooding, power outages and the consequences resulting from them may not be covered adequately, or may not be covered at all, by our insurance policies. If we were to incur substantial liabilities that were not covered by our insurance, or if our business operations were interrupted for more than a short period of time, we could incur costs and losses that could materially and adversely affect our results of operations.

We may not be able to obtain the necessary PRC government authorizations, land use rights certificates or building ownership certificates for some of our properties and plants.

Pursuant to an agreement entered into in July 2008 with Hebei Bishi, WSP China acquired Mengfeng, a company located in Inner Mongolia, China. However, we have not obtained the necessary PRC government authorizations for Mengfeng’s blast furnace project, the land use rights certificate for a piece of property of approximately 89,233 square meters and any of the ownership certificates for Mengfeng’s buildings. In addition, we do not have the land use rights certificates or building ownership certificates for certain plants or facilities owned by three of our other subsidiaries. We are in the process of obtaining PRC government authorizations, land use rights certificates and building ownership certificate for these properties. However, we may not be able to obtain them. If we fail to obtain such authorization or certificates in a timely manner, or at all, we may be subject to severe penalties and fines, which could materially and adversely affect our financial condition and results of operations.

Economic and political conditions and instability in Thailand may adversely affect our operations.

WSP Pipe’s operations are subject to the changing economic and political conditions in Thailand. Our results of operations may be influenced in part by the political situation in Thailand, which is unstable. The political upheavals may have a severe adverse effect on Thailand’s economic and democratic development. Current and future political instability in Thailand could have a material adverse effect on our businesses and operations. In addition, we cannot assure you that the Thai government would not amend foreign ownership rules or impose additional restrictions on foreign ownership that would have an adverse effect on our business.

We are subject to litigation proceedings brought by third-parties. If any of the proceedings against us is successful, it may have an adverse effect on our financial condition and operating results.

We are subject to litigation proceedings brought by third-parties. For instance, in August 2009, Western Oil Gas Development Corp. brought a lawsuit against us in a district court in Canadian County, Oklahoma, alleged that a casing pipe provided by us caused damages to its well. In May 2010, WSP China was subject to a lawsuit in a district court in Desoto Parish, Louisiana, as the manufacturer of a casing pipe used in an alleged oil and gas well operation failure. In August 2010, WSP China was subject to a third-party petition in the District Court of Lipscomb County, Texas, as the manufacturer of a casing pipe in an alleged oil and gas well operation failure. In March 2011, Cimarex Energy Co. filed a lawsuit against us, WSP China, Houston OCTG and other defendants in Nueces County, Texas, seeking total damages in the amount of $11.0 million resulting from defects in casing pipes provided by us. In addition, certain of our subsidiaries are subject to litigation proceedings brought by our suppliers for raw materials and services that we have purchased from them and additional damages, we have incurred significant costs as a result of these proceedings, including settlement payments. See “Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Legal proceedings” for further information about the lawsuits. We believe that the allegations in these cases are without merit and we intend to vigorously defend ourselves against the claims. The outcome of these cases, like other litigation proceedings, is uncertain. We cannot assure you that in the future we will not be subject to litigation proceedings brought by third-parties arising from our operations or products. Regardless of their merit, litigation and other preparations undertaken to defend such cases can be costly, and we may incur substantial costs and expenses in doing so. They may also divert the attention of our management from our business and operations. If any of the cases against us is successful, it may result in substantial monetary liabilities, which may have a material adverse effect on our financial condition and operating results.

Risks related to doing business in China

China’s economic, political and social conditions, as well as governmental policies, could affect the financial markets in China, our liquidity and access to capital and our ability to operate our business.

Substantially all of our business operations are conducted in China. Accordingly, our results of operations, financial condition and prospects are subject to a significant degree to economic, political and legal developments in China. China’s economy differs from the economies of developed countries in many respects, including with respect to the amount of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. While the PRC economy has experienced significant growth in the past 30 years, growth has been uneven across different regions and among various economic sectors of China. The PRC government has implemented various measures to encourage economic development and guide the allocation of resources. Some of these measures benefit the overall PRC economy, but may have a negative effect on us. For example, our financial condition and results of operations may be adversely affected by government control over capital investments or changes in tax regulations that are applicable to us. More generally, if the business environment in China deteriorates from the perspective of domestic or international investors, our business in China may also be adversely affected.

Uncertainties with respect to the PRC legal system could materially and adversely affect us.

We conduct our business primarily through our subsidiaries in China. PRC laws and regulations govern our operations in China. Our subsidiaries are generally subject to laws and regulations applicable to foreign investments in China and, in particular, laws applicable to wholly foreign-owned enterprises. The PRC legal system is based on written statutes. Prior court decisions may be cited for reference but have limited precedential value.

Since 1979, PRC legislation and regulations have significantly enhanced the protections afforded to various forms of foreign investments in China. However, China has not developed a fully integrated legal system and recently enacted laws and regulations that may not sufficiently cover all aspects of economic activities in China. In particular, because these laws and regulations are relatively new, and because of the limited volume of published decisions and their non-binding nature, the interpretation and enforcement of these laws and regulations, including those related to bill financing arrangements (See “Item 4. Information on the Company—B. Business Overview—Regulations—Regulations on negotiable instruments” and “Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Bill financing”), involve uncertainties. In addition, the PRC legal system is based in part on government policies and internal rules (some of which are not published on a timely basis or at all) that may have a retroactive effect. As a result, we may not be aware of our violation of these policies and rules until some time after the violation. In addition, any litigation in China, regardless of outcome, may be protracted and result in substantial costs and diversion of resources and management attention.

PRC regulations relating to offshore investment activities by PRC residents may increase our administrative burden and restrict our domestic, overseas and cross-border investment activity. If our shareholders who are PRC residents fail to make any required applications and filings under such regulations, we may be unable to distribute profits and may become subject to liability under PRC laws.

In October 2005, the PRC State Administration of Foreign Exchange, or SAFE, issued the Notice on Issues Relating to the Administration of Foreign Exchange in Fund-Raising and Return Investment Activities of Domestic Residents Conducted via Offshore Special Purpose Companies, or SAFE Circular 75. To further clarify and simplify the implementation of SAFE Circular 75, SAFE issued the Implementing Rules Relating to the Administration of Foreign Exchange in Fund-Raising and Round-trip Investment Activities of the Domestic Residents Conducted via Offshore Special Purpose Companies, or Circular 19, effective on July 1, 2011. According to SAFE Circular 75 and Circular 19, prior to establishing or assuming control of an offshore enterprise for the purpose of financing that offshore enterprise with assets or equity interests in an onshore enterprise in China, each PRC resident, whether a natural or legal person, must complete certain overseas investment foreign exchange registration procedures with the relevant local SAFE branch. An amendment to the registration with the local SAFE branch is required to be filed upon certain prescribed events. If our shareholders who are PRC citizens or residents do not complete their registration with the local SAFE authorities, our PRC subsidiaries will be prohibited from distributing their profits and proceeds from any reduction in capital, share transfer or liquidation to us, and we may be restricted in our ability to contribute additional capital to our PRC subsidiaries.

19

We are committed to complying, and to ensuring that our shareholders who are PRC citizens or residents, comply with the SAFE Circular 75 requirements. However, we may not at all times be fully aware or informed of the identities of all our beneficial owners who are PRC citizens or residents, and we may not always be able to compel our beneficial owners to comply with the SAFE Circular 75 requirements. As a result, we cannot assure you that all of our shareholders or beneficial owners who are PRC citizens or residents will at all times comply with, or in the future make or obtain any applicable registrations or approvals required by, SAFE Circular 75 or other related regulations. In the event that a PRC shareholder with a direct or indirect stake in an offshore parent company fails to make the required SAFE registration, the PRC subsidiaries of that offshore parent company may be prohibited from making distributions of profit to the offshore parent and from paying the offshore parent proceeds from any reduction in capital, share transfer or liquidation in respect of the PRC subsidiaries. Furthermore, failure to comply with the various SAFE registration requirements described above could result in liability under PRC law for foreign exchange evasion.

One of our current beneficial owners, Mr. Longhua Piao, who is a PRC resident, has registered with the local SAFE branch as required under these regulations relating to offshore investment activities. However, if Mr. Piao does not timely amend his SAFE registrations pursuant to regulations or if future beneficial owners of our company who are PRC residents do not comply with the registration procedures, such beneficial owners may be subject to fines and legal sanctions, our ability to contribute additional capital into our PRC subsidiaries and our PRC subsidiaries’ ability to distribute dividends to our company may be limited and our business may be adversely affected.

The regulations on mergers and acquisitions of PRC enterprises may delay or inhibit our ability to complete certain mergers and acquisitions which could affect our ability to expand our business or maintain our market shares.

On August 8, 2006, six PRC regulatory agencies, namely, the PRC Ministry of Commerce, the State Assets Supervision and Administration Commission, the State Administration for Taxation, the State Administration for Industry and Commerce, the China Securities Regulatory Commission and SAFE, jointly adopted the Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the New M&A Rule, which became effective on September 8, 2006 and was amended on June 22, 2009. Among other things, this New M&A Rule, established additional procedures and requirements that could make merger and acquisition activities by foreign investors more time-consuming and complex, including requirements in some instances that the Ministry of Commerce be notified in advance of any change-of-control transaction in which a foreign investor takes control of a PRC domestic enterprise. In the future, we may grow our business in part by acquiring complementary businesses. Complying with the requirements of the New M&A Rule to complete such transactions could be time-consuming, and any required approval processes, including obtaining approval from the Ministry of Commerce, may delay or inhibit our ability to complete such transactions, which could affect our ability to expand our business or maintain our market share.

Restrictions on currency exchange may limit our ability to utilize our revenues effectively.

The PRC government imposes controls on the convertibility of Renminbi into foreign currencies and, in certain cases, the remittance of currency out of China. We receive much of our revenues in Renminbi. Under our current structure, our income is primarily derived from dividend payments from our PRC subsidiaries. Shortages in the availability of foreign currency may restrict the ability of our PRC subsidiaries to remit sufficient foreign currency to pay dividends or make other payments to us, or otherwise satisfy their foreign currency denominated obligations. Under the existing PRC foreign exchange regulations, payments of current account items, including profit distributions, interest payments and expenditures from trade-related transactions, can be made in foreign currencies without prior approval from the SAFE by complying with certain procedural requirements. However, approval from appropriate government authorities is required where Renminbi is to be converted into foreign currency and remitted out of China to pay capital expenses such as the repayment of bank loans denominated in foreign currencies. The PRC government may also at its discretion restrict access in the future to foreign currencies for current account transactions. If the foreign exchange control system prevents us from obtaining sufficient foreign currency to satisfy our currency demands, we may not be able to pay dividends in foreign currencies to our shareholders, including holders of our ADSs.

Fluctuations in exchange rates could adversely affect our business as well as result in foreign currency exchange losses.

Our financial statements are expressed in U.S. dollars. The functional currency of WSP Holdings is U.S. dollars and the functional currency of our PRC operating subsidiaries is Renminbi. The value of the Renminbi against the U.S. dollar and other currencies is affected by, among other things, changes in China’s political and economic conditions and China’s foreign exchange policies. On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of the Renminbi to the U.S. dollar. Under the new policy, the Renminbi was permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. Following the removal of the U.S. dollar peg, the Renminbi appreciated more than 20% against the U.S. dollar over three years. From July 2008 until June 2010, however, the Renminbi traded stably within a narrow range against the U.S. dollar.

20

There remains significant international pressure on the PRC government to adopt a more flexible currency policy, which could result in a further and more significant appreciation of the Renminbi against foreign currencies. On June 20, 2010, the People’s Bank of China announced that the PRC government would reform the Renminbi exchange rate regime and increase the flexibility of the exchange rate. Between June 20, 2010 and December 31, 2012, the Renminbi appreciated by approximately 9.1% against the U.S. dollar.

A substantial portion of our sales is denominated in U.S. dollars and Renminbi, while substantially all of our costs and expenses are denominated in Renminbi. As a result, appreciation of Renminbi could increase our costs. If we were to increase our prices to compensate for the increased costs, we may decrease the market competitiveness of our products. This could result in a decrease in our international sales and materially and adversely affect our business.

In addition, as we rely primarily on dividends paid to us by WSP China, our operating subsidiary in China for our cash requirement, any significant revaluation of the Renminbi may have a material adverse effect on our financial condition and results of operations. The value of, and any dividends payable on, our ADSs in foreign currency terms will also be affected. For example, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, an appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amount available to us. Conversely, when converting the U.S. dollars we received from our financing activities and oversea sales into Renminbi for our operations, any appreciation of the Renminbi against the U.S. dollar will decrease the Renminbi amount we receive from the conversion.

There are only limited hedging transactions available in China to reduce our exposure to exchange rate fluctuations. From time to time, we entered into foreign currency forward contracts to limit the effects of foreign exchange rate fluctuations on our financial results. However, the availability and effectiveness of these transactions may be limited and we may not be able to successfully hedge our exposure.

Our business benefits from certain PRC government incentives, and expiration of, or changes to, these incentives could have a material adverse effect on our results of operations.

The PRC government has provided various incentives to foreign invested enterprises. Based on an approval in September 2008 and effective retrospectively from January 1, 2008, WSP China was classified as a “high and new technology enterprise” by the Chinese government. This classification allows WSP China to enjoy a preferential tax rate of 15% instead of the general 25% income tax rate until December 31, 2010. In September 2011, we obtained an approval from the PRC government for a renewal of the “high and new technology enterprise” status, effective retrospectively from January 1, 2011. When our current preferential income tax rate treatment expires in December 2013, WSP China may not continue to qualify as a “high and new technology enterprise” and enjoy the benefit from the preferential tax rate. See “Item 5. Operating and Financial Review and Prospects—A. Operating Results—Taxation” for more details.

Furthermore, value-added tax, or VAT, in China is charged on sales based on the sales price of our products to customers at a general rate of 17%. We are deemed to have paid a 4% VAT tax based on the general rate minus a 13% VAT refund on export sales, which we are entitled to receive upon filing the VAT returns. In July 2007, the PRC tax authorities reduced such refund to 5% for certain steel products, which did not include seamless OCTG products. However, there is no assurance that the rate of refund for seamless OCTG products will not be reduced by the PRC tax authorities in the future, and a decrease of the refund will have a material adverse effect on our results of operations.

We may be treated as a resident enterprise for PRC tax purposes under the New EIT Law, which may subject us to PRC income tax for our income originated both within and outside the PRC and PRC income tax withholding for any dividends we pay to our non-PRC shareholders.

Under the New Enterprise Income Tax Law, or the New EIT law, enterprises established under the laws of non-PRC jurisdictions, but whose de facto management body is located in the PRC, may be treated as “resident enterprises” for PRC tax purposes. The implementing rules of the New EIT Law define de facto management as having substantial and overall management and control over the production and operations, personnel, accounting, and properties of the enterprise. Based on our analysis of the current facts, we believe that WSP Holdings and its subsidiary, First Space Holdings Limited, or FSHL, should not be treated as resident enterprises for PRC tax purposes. However, the New EIT Law and its implementing rules are ambiguous in terms of some definitions, requirements and detailed procedures, and currently no official interpretation or application of this new resident enterprise classification is available. Therefore, it is unclear as to how tax authorities will determine tax residency based on the facts of each case. For the years ended December 31, 2010, 2011 and 2012, our calculation of income taxes generally reflects our status as a non-China tax resident company. If the PRC governmental authorities hold that WSP Holdings or FSHL should be treated as a resident enterprise for PRC tax purposes after January 1, 2008, the effective date of the New EIT Law, our worldwide income will be subject to PRC income tax at the 25% uniform tax rate, which will include any dividend income we receive from our subsidiaries, unless such dividend income is otherwise exempted from taxable income under the New EIT Law. If we are required to pay income tax for dividends we receive from our subsidiaries, it will materially and adversely affect our financial condition and results of operations.

21

Moreover, unlike the previous PRC tax law, which specifically exempts withholding tax on any dividends payable to non-PRC shareholders, the New EIT Law and its implementing rules provide that a withholding tax rate of 10% will be applicable to dividends payable to non-PRC shareholders that are derived from sources within the PRC, unless a tax treaty exists between the PRC and the relevant jurisdictions where such non-PRC shareholders reside and such treaty provides for a reduction or exemption of the relevant tax. We are a Cayman Islands holding company and our income mainly comes from dividends we receive from our subsidiaries, primarily from those located in China. In 2009, FSHL was recognized by the relevant tax authorities as a tax resident company in the Hong Kong Special Administrative Region, a withholding tax at 5% will be applicable on PRC dividends paid to FSHL. The relevant tax authorities may evaluate FSHL China’s qualification as a tax resident company in the Hong Kong Special Administrative Region. We cannot assure you that FSHL will continue to qualify for such status under evaluations by the tax authorities in the future. In the event the status of FSHL as a tax resident company in the Hong Kong Special Administrative Region is discontinued, dividends payable to FSHL will become subject to the standard PRC enterprise income tax rate, which could materially increase our tax obligations, which could have a material adverse effect on our financial condition and results of operations.

As uncertainties remain regarding the interpretation and implementation of the New EIT Law and its implementation rules, we cannot assure you that if we are regarded as a PRC resident enterprise, any dividends to be distributed by us to our non-PRC shareholders and ADS holders would not be subject to any PRC withholding tax at a rate of up to 10%. Similarly, any gain realized on the transfer of ADSs or shares by non-PRC investors may be also subject to a 10% withholding tax if such gain is regarded as income derived from sources within China. We are a Cayman Islands holding company and our income mainly comes from dividends we receive from our subsidiaries, primarily from those located in China. Due to the lack of publicly available interpretations on this subject, there is uncertainty as to whether the dividends we pay to our non-PRC shareholders or the gain you may realize from the transfer of our ordinary shares or ADSs will be subject to the 10% withholding tax. If we are required under the New EIT Law to withhold PRC income tax on such dividends, your investment in our ADSs may be materially and adversely affected.

We face risks related to natural calamities or health epidemics, which could disrupt our operations.

Our business could be materially and adversely affected by natural calamities or health epidemics such as swine influenza, avian influenza, severe acute respiratory syndrome or other epidemics. Any recurrence of natural calamities or epidemics in China or elsewhere may have a material and adverse effect on our business operations. Such recurrence may restrict our ability to travel or ship our products inside or outside of China, or may require us to temporary close our manufacturing facilities. Such closures or travel or shipment restrictions would severely disrupt our business operations and adversely affect our results of operations. We have not adopted any written preventive measures or contingency plans to combat any future outbreak of swine influenza, avian influenza or any other epidemics.

Labor laws in China may adversely affect our results of operations.

On June 29, 2007, the PRC government promulgated the Labor Contract Law of the PRC, or the Labor Contract Law, which became effective on January 1, 2008. The Labor Contract Law imposes greater liabilities on employers and significantly impacts the cost of an employer’s decision to reduce its workforce. Further, it requires certain terminations to be based upon seniority and not the merits of employees. In the event we decide to significantly change or decrease our workforce, the Labor Contract Law could adversely affect our ability to enact such changes in a manner that is most advantageous to our business or in a timely and cost effective manner, thus materially and adversely affecting our financial condition and results of operations.

22

Risks related to our ADSs

Substantial future sales or perceived sales of our ADSs in the public market could cause the price of our ADSs to decline.

Additional sales of our ordinary shares in the public market, or the perception that these sales could occur, could cause the market price of our ADSs to decline. In addition, certain holders of our ordinary shares have the right to cause us to register the sale of a certain number of our shares under the Securities Act of 1933, as amended, or the Securities Act. Registration of these shares under the Securities Act would result in these shares becoming freely tradable without restriction under the Securities Act immediately upon the effectiveness of the registration. Sales of these registered shares in the public market could cause the price of our ADSs to decline.

You may not have the same voting rights as the holders of our ordinary shares and may not receive voting materials in time to be able to exercise your right to vote.

Except as described in this annual report and in the deposit agreement, holders of our ADSs will not be able to exercise voting rights attaching to the shares represented by our ADSs on an individual basis. Holders of our ADSs will appoint the depositary or its nominee to vote the shares represented by the ADSs. You may not receive voting materials in time to instruct the depositary to vote and it is possible that you, or persons who hold their ADSs through brokers, dealers or other third parties, will not have the opportunity to exercise a right to vote. Upon our written request, the depositary will mail to you a shareholder meeting notice which contains, among other things, a statement as to the manner in which your voting instructions may be given, including an express indication that such instructions may be given or deemed given to the depositary to give a discretionary proxy to a person designated by us if no instructions are received by the depositary from you on or before the response date established by the depositary. However, no voting instruction shall be deemed given and no such discretionary proxy shall be given with respect to any matter as to which we inform the depositary that (i) we do not wish such proxy to be given, (ii) substantial opposition exists, or (iii) such matter materially and adversely affect the rights of shareholders.

Your right to participate in any future rights offerings may be limited, which may cause dilution to your holdings and you may not receive cash dividends if it is impractical to make them available to you.

We may from time to time distribute rights to our shareholders, including rights to acquire our securities. However, we cannot make rights available to you in the United States unless we register the rights and the securities to which the rights relate under the Securities Act or an exemption from the registration requirements is available. Also, under the deposit agreement, the depositary bank will not make rights available to you unless the distribution to ADS holders of both the rights and any related securities are either registered under the Securities Act or exempted from registration under the Securities Act. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act. Accordingly, you may be unable to participate in our rights offerings and may experience dilution in your holdings.

In addition, the depositary of our ADSs has agreed to pay to you the cash dividends or other distributions it or the custodian receives on our ordinary shares or other deposited securities after deducting its fees and expenses. You will receive these distributions in proportion to the number of ordinary shares your ADSs represent. However, the depositary may, at its discretion, decide that it is inequitable or impractical to make a distribution available to any holders of ADSs. For example, the depositary may determine that it is not practicable to distribute certain property through the mail, or that the value of certain distributions may be less than the cost of mailing them. In these cases, the depositary may decide not to distribute that property and you will not receive that distribution.

We are a Cayman Islands company and, because judicial precedent regarding the rights of shareholders is more limited under Cayman Islands law than that under U.S. law, you may have less protection for your shareholder rights than you would under U.S. law.

Our corporate affairs are governed by our amended and restated memorandum and articles of association, the Cayman Islands Companies Law and the common law of the Cayman Islands. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as that from English common law, which has persuasive, but not binding, authority on a court in the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws than the United States. In addition, some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands.

23

As a result of all of the above, public shareholders of our company may have more difficulty in protecting their interests in the face of actions taken by management, members of the board of directors or the controlling shareholder of our company than they would as shareholders of a U.S. public company.

You may have difficulty enforcing judgments obtained against us.

We are a Cayman Islands company and most of our assets are located outside of the United States. Most of our current operations are conducted in China. In addition, most of our directors and officers are nationals and residents of countries other than the United States. A substantial portion of the assets of these persons is located outside of the United States. As a result, it may be difficult for you to effect service of process within the United States upon these persons. It may also be difficult for you to enforce in U.S. courts judgments on the civil liability provisions of the U.S. federal securities laws against us and our officers and directors, most of whom are not residents in the United States and the substantial majority of whose assets are located outside of the United States. In addition, there is uncertainty as to whether the courts of the Cayman Islands or China would recognize or enforce judgments of U.S. courts.

We may be classified as a passive foreign investment company, which could result in adverse U.S. federal income tax consequences to U.S. holders of our ADSs or ordinary shares.

Based on the market price of our ADSs, the value of our assets and the composition of our income and assets, we do not believe we were a “passive foreign investment company,” or PFIC, for U.S. federal income tax purposes for our taxable year ended December 31, 2012. However, the application of the PFIC rules is subject to uncertainty in several respects, and we cannot assure you the U.S. Internal Revenue Service will not take a contrary position. A non-U.S. corporation will be considered a PFIC for any taxable year if either (i) at least 75% of its gross income is passive income or (ii) at least 50% of the value of its assets (based on an average of the quarterly values of the assets) is attributable to assets that produce or are held for the production of passive income. We must make a separate determination each year as to whether we are a PFIC, and accordingly, even if we were not a PFIC for the taxable year that ended December 31, 2012, our PFIC status may change in the current taxable year or a future taxable year. If we are treated as a PFIC for any taxable year during which a U.S. Holder (as defined in “Item 10. Additional Information—E. Taxation—United States federal income taxation—Passive foreign investment company”) held an ADS or an ordinary share, certain adverse U.S. federal income tax consequences could apply to that U.S. Holder. See “Item 10. Additional Information—E. Taxation— United States federal income taxation—Passive foreign investment company.”

Our ADSs may not comply with the minimum listing requirements of the New York Stock Exchange. Delisting could adversely affect the liquidity of our ADSs and the market price of our ADSs could decrease, and our ability to obtain adequate financing for the continuation of our operations would be substantially impaired.

Our ADSs are currently listed on the New York Stock Exchange. The New York Stock Exchange has minimum requirements that a company must meet in order to remain listed on the New York Stock Exchange. These requirements include maintaining a minimum average closing price of $1.00 per share over a period of consecutive 30 trading days. On August 1, 2011, we received notice from the NYSE that the price of our ADSs was below listing requirements. To regain compliance with this requirement, we implemented a change in the ratio of our ADSs to ordinary shares from one ADS representing two ordinary shares to one ADS representing ten ordinary shares, effective as of February 15, 2012. For our ADSs holders, this ratio change has the same effect of a five-for-one ADS reverse split. However, this ratio change may not ensure our future compliance with the New York Stock Exchange continued listing standards relating to minimum average closing price if our ADS price continues to decline. If our ADSs are delisted as a result of our failure to comply with any of the New York Stock Exchange’s minimum listing requirements, the liquidity of our ADSs would be adversely affected, the market price of our ADSs could further decrease, and our ability to obtain adequate financing for the continuation of our operations would be substantially impaired, which could have a material adverse effect on our financial condition and results of operations.

Item 4.INFORMATION ON THE COMPANY

A.History and Development of the Company

Our legal and commercial name is WSP Holdings Limited. We are a holding company incorporated in the Cayman Islands and conduct substantially all of our operations through our subsidiaries in China. WSP China was initially set up as a PRC-foreign joint venture under PRC laws in November 1999. WSP China underwent a series of corporate reorganizations and, in August 2006, became a wholly-owned subsidiary of FSHL, a company incorporated in the British Virgin Islands. In preparation for our initial public offering, WSP Holdings Limited was incorporated in the Cayman Islands in November 2006. WSP Holdings Limited was owned 69.4% and 30.6% by EMH and UMW China Ventures, respectively, at the time of its incorporation. EMH is wholly-owned by our chairman and chief executive officer, Mr. Longhua Piao, and UMW China Ventures is an indirect wholly-owned subsidiary of UMW. In December 2006, WSP Holdings acquired the entire share capital of FSHL from its shareholders through a share exchange, and WSP Holdings became the ultimate holding company of our businesses.

In January 2007, we and three other investors established WSP Industries Canada Inc., or WSP Industries, in British Columbia, Canada. As part of our international expansion strategy review, we dissolved and liquidated WSP Industries in May 2009.

In April 2008, FSHL and Liaoning Steel Pipe Co., Ltd., or Liaoning Pipe, established Liaoyang Seamless, a limited liability company with registered capital in the amount of $40 million, in Liaoyang, Liaoning province, China. FSHL holds a 70% equity interest in Liaoyang Seamless. The purpose of Liaoyang Seamless is to manufacture finished OCTG products. In April 2008, WSP China established a wholly-owned subsidiary, Songyuan Seamless, in Songyuan, Jilin province, China. The purpose of Songyuan Seamless is to manufacture finished OCTG products.  In January 2013, Songyuan Seamless entered into an equity transfer agreement with Liaoning Pipe to acquire all of Liaoning Pipe’s 30% equity interest in Liaoyang Seamless for total consideration of RMB49.0 million ($7.9 million). The transaction was funded by selling certain assets of Liaoyang Seamless to Liaoning Pipe. Liaoyang Seamless also entered into a lease agreement with Liaoning Pipe to lease back these assets to continue Liaoyang Seamless’s operations. The term of the lease is for three years and expires on December 31, 2015 with monthly rent payment of RMB 434,000 (approximately $69,000). The acquisition transaction was completed in July 2013.

In April 2008, FSHL established a wholly-owned subsidiary, Houston OCTG, in Houston, Texas, United States. The purpose of Houston OCTG was to serve as our sales office for the North and South American markets. Following the imposition of countervailing and anti-dumping duties by the U.S. government, we completed construction of one threading line with an annual production capacity of 120,000 tonnes in July 2010 and another heat treatment line with an annual production capacity of 100,000 tonnes in April 2011 through Houston OCTG to counteract the impact. In November 2012, we sold production facilities, including land, equipment and related permits and licenses, held by Houston OCTG to Southern Tube LLC, an affiliate of Nippon Steel & Sumitomo Metal Corporation for total consideration of $43.0 million. In connection with the sale of these assets, we incurred a loss on disposal of approximately $5.1 million in the second half of 2012.

In July 2008, WSP China entered into an agreement with Hebei Bishi to acquire 100% equity ownership of Mengfeng, in Tuoketuo County, Inner Mongolia Autonomous Region, China, with a total consideration of approximately $40.5 million. Mengfeng was approved as a seamless steel pipe manufacturer and its current primary business is to provide raw materials for our subsidiaries in China. As of the date of this annual report, WSP China has paid a total of approximately $38.2 million to Hebei Bishi under this agreement.

In October 2008, WSP China established two new wholly-owned subsidiaries, Bazhou Seamless, and Luntai County Longhua Mining Industrial Co., Ltd., or Luntai Mining, in Kuerle, Xinjiang Autonomous Region, China. The purpose of these two companies is to manufacture finished OCTG products. In November 2010, we dissolved and liquidated Luntai Mining due to change of operational strategy.

In April 2009, WSP China, together with two unrelated individuals, established Chaoyang Seamless. WSP China held a 51% equity interest in Chaoyang Seamless. In January 2012, we entered into an agreement with a third party to transfer our entire 51% equity interest in Chaoyang Seamless for nominal cash consideration. The disposal transaction was completed in January 2012.

Jiangsu Fanli Pipe Co., Ltd., or Jiangsu Fanli, was established in China on April 16, 2004 as a limited liability company with a registered capital of $1.5 million. In April 2006, the registered capital of Jiangsu Fanli was increased to $7.3 million and WSP China acquired 70% equity interest in Jiangsu Fanli through capital injection. The remaining equity interest was owned 24%, 4% and 2% by Mr. Cheng Huang, Mr. Xiang Huang and Mr. Jianming Gu, respectively, all of whom are independent third parties. In February 2010, WSP China, together with three non-controlling shareholders entered into an agreement with Zhejiang Jianli Company Limited, or Zhejiang Jianli, to transfer their entire equity interests in Jiangsu Fanli to Zhejiang Jianli. Pursuant to the agreement, WSP China retained certain assets of Jiangsu Fanli, including current assets, and assumed all liabilities incurred before the disposal. On the same date, WSP China entered into another agreement with Zhejiang Jianli to purchase certain hot-rolling production assets from Zhejiang Jianli. These two transactions have been accounted as nonmonetary exchange transactions in accordance with an authoritative guidance and, accordingly, the exchanges of nonmonetary assets between WSP China and Zhejiang Jianli are recorded based on the fair value of the assets exchanged. The transactions were completed in February 2010.

25

In February 2010, through our wholly-owned subsidiary FSHL, we acquired WSP Pipe from Mr. Longhua Piao, our chairman and chief executive officer for no monetary consideration. WSP Pipe was a shell company incorporated in the Thai-Chinese Rayong Industrial Zone, Thailand. In 2011, we completed the construction of an OCTG pipe manufacturing and sales facility through WSP Pipe, which consists of two hot-rolling production lines with a combined annual production capacity of 180,000 tonnes. We completed the construction of and began trial production on one hot-rolling production line in May 2011 and the other in September 2011. We also completed the construction of one threading line with an annual production capacity of 50,000 tonnes in October 2011.

In February 2010, Bazhou Seamless established a wholly-owned subsidiary, Kuitun Seamless, in Kuitun, Xinjiang Autonomous Region, China. The purpose of Kuitun Seamless is to provide raw materials for Bazhou Seamless. In July 2011, we disposed of our entire equity interest in Kuitun Seamless to Shandong Shiheng Special Steel Co., Ltd. for a cash consideration of $9.8 million.

The following diagram illustrates our corporate structure as of the date of this annual report.

 

(1)In November 2012, we sold production facilities held by Houston OCTG to a third party for approximately $43.0 million.

(2)In January 2013, Songyuan Seamless entered into an Equity Transfer Agreement with Liaoning Pipe to acquire all of Liaoning Pipe’s 30% equity interest in Liaoyang Seamless for total consideration of RMB49.0 million ($7.9 million).

Going private transaction

In December 2011, our board of directors formed a special committee of independent directors consisting of Messrs. Dennis D. Zhu, Weidong Wang and Michael Muhan Liu after receiving a non-binding proposal letter from H.D.S. Investments LLC, or HDS, notifying the board of its interest in acquiring all of our shares in a possible going private transaction for US$0.60 per ADS (before the effectiveness of our ADS to ordinary share ratio change in February 2012) in cash, subject to certain conditions.

In February 2013, we announced that we had entered into an Agreement and Plan of Merger, or the Merger Agreement, with WSP OCTG Group Ltd., or Parent, a company owned by HDS, and JM OCTG Group Ltd., a company with limited liability and a direct wholly-owned subsidiary of Parent, or Merger Sub.  The transaction contemplated under the Merger Agreement represents a total transaction value of approximately $893.6 million, including the assumption of our Company’s outstanding debt.

Subject to satisfaction or waiver of the closing conditions in the Merger Agreement, Merger Sub will merge with and into our Company, with our Company continuing as the surviving corporation.  Pursuant to the Merger Agreement, each of our ordinary shares issued and outstanding immediately prior to the effective time of the Merger will be cancelled and cease to exist in exchange for the right to receive $0.32 without interest, and each ADS will represent the right to surrender the ADS in exchange for $3.20 in cash without interest, except for (a) ordinary shares held of record by EMH and UMW China Ventures, which will be contributed to Parent immediately prior to the merger in exchange for equity interests of Parent, and (b) ordinary shares owned by shareholders who have validly exercised and have not effectively withdrawn or lost their rights to dissent from the merger under the Cayman Islands Companies Law, or the dissenting shares, which will be cancelled for the right to payment of fair value of the dissenting shares in accordance with the Cayman Islands Companies Law.

The $0.32 per ordinary share or $3.20 per ADS offer represents a premium of 60.0% over our closing price of $2.00 per ADS (adjusted for the change in the ratio of the ADSs from one ADS representing two ordinary shares to one ADS representing ten ordinary shares effective February 15, 2012) on December 12, 2011, the last trading day prior to our announcement of its receipt of a “going-private” proposal, and a premium of 52.5% to the volume-weighted average closing price calculated using the market data quoted on the New York Stock Exchange of the ADSs during the 60 trading days prior to December 12, 2011.

HDS has provided us with a limited guarantee in favor of us guaranteeing the payment of certain monetary obligations of Parent and Merger Sub arising under the Merger Agreement up to a capped amount. HDS has committed, at or prior to the closing of the Merger, to contribute to Parent, and to cause Parent to contribute to Merger Sub, an equity investment in an amount sufficient to fund the merger consideration and related transaction expenses upon the terms set forth in an equity commitment letter.

Our board of directors, acting upon the unanimous recommendation of the special committee, approved the Merger Agreement and the merger and resolved to recommend that our shareholders vote to authorize and approve the Merger Agreement and the merger. The special committee negotiated the terms of the Merger Agreement with the assistance of its legal and financial advisors.

27

On August 15, 2013, upon the approval of the special committee, we entered into an amendment to the Merger Agreement with Parent and Merger Sub to extend the termination date of the Merger Agreement to December 31, 2013.

The merger, which is currently expected to close during the fourth quarter of 2013, is subject to the authorization and approval of the Merger Agreement by an affirmative vote of shareholders representing at least two-thirds of the ordinary shares present and voting in person or by proxy as a single class at a meeting of our shareholders, as well as certain other customary closing conditions. EMH and UMW collectively beneficially own sufficient ordinary shares to approve the Merger Agreement and the merger and have agreed to vote in favor of such approval. If completed, the merger will result in our becoming a privately-held company and our ADSs no longer being listed on the New York Stock Exchange. However, we cannot assure you that the merger will be completed.

For additional information regarding the going private transaction, please refer to our Schedule 13E-3/A and preliminary proxy statement and a Form 6-K filed with the SEC on June 27, 2013 and August 15, 2013.

The terms of credit and other banking facilities provided to WSP Pipe by Bangkok Bank Public Company Limited, or Bangkok Bank, require us to remain a public company listed on the New York Stock Exchange. We are currently in discussions with Bangkok Bank regarding obtaining a waiver for this requirement.

B.Business Overview

We are a leading Chinese manufacturer of seamless OCTG, including casing, tubing and drill pipes used for oil and natural gas exploration, drilling and extraction. We sell our products in both domestic and international markets. In China, we target sales of our products primarily at leading Chinese oil companies. For instance, in 2012, we were one of the three largest OCTG suppliers to CNPC and one of the two PRC-based non-API OCTG suppliers to Sinopec. In the international markets, we have established an extensive overseas customer base, covering oilfields in North and South America, the Middle East, Asia, Africa and Russia.

We offer a comprehensive range of seamless OCTG products to our customers. Our product portfolio can generally be divided into two categories:

·API products, which are products manufactured according to the standards formulated by the API; and

·Non-API products, which are products tailor-made to meet our customers’ specifications, and that are generally manufactured to a higher standard than API products.

To offer our customers a one-stop-shop solution for their OCTG requirements for oil and gas drilling and extraction, we focus our research and development efforts on producing higher margin, higher value-added non-API products. We have developed nine series of non-API products that are suitable for challenging drilling conditions, including deep or super-deep wells, high temperature, highly pressurized and highly corrosive conditions. For example, our non-API products have been used in wells with a depth of over 7,800 meters in Puguang gas fields in Sichuan Province, China. In addition to our seamless OCTG products, we also sell green pipes to our customers upon request. In 2009, 2010 and 2011, we sold steel billets and other unfinished products to meet our customers’ production requirements. We also sold iron ore pellets in 2009 and 2010.

In 2009 and 2010, we experienced a decrease in both sales of API and non-API products primarily due to decreased demand for our OCTG products as a result of the anti-dumping and countervailing duties imposed on Chinese OCTG products by the United States government, the worldwide economic crisis and oversupply in the domestic PRC market. In 2011, we experienced an increase in both sales of API and non-API products primarily due to increased demand for our OCTG products from the international markets such as South America, Middle East and Central Asia. However, we experienced a decrease in both sales of API and non-API products, primarily due to decreases in sales volume for both API and non-API products. Sales of our non-API products as a percentage of net revenues increased from 14.9% in 2010 to 21.1% in 2011, but decreased to 16.1% in 2012. For the same periods, sales of API products accounted for 58.9%, 65.0% and 71.4%, respectively, of our net revenues.

Additionally, in 2009, we entered into a five-year agreement to purchase iron ore pellets from a supplier in Brazil, on a yearly basis from 2010 through 2014. In 2010, we purchased 175,000 tonnes of iron ore pellets and sold them to a domestic steel company. Sales of iron ore pellets as a percentage of our net revenues was 6.8% in 2010. In 2011 and 2012, we did not purchase any iron ore pellets due to our internal lack of iron ore pellet requirements and low market demand for sales of iron ore pellets. However, in 2012, we received commissions of approximately $2.7 million from our supplier for finding a third-party buyer for 334,117 tonnes of iron ore pellets.

As of December 31, 2012, our key operating assets included eighteen threading lines and two drill pipe production lines with an aggregate annual production capacity of approximately 1,404,000 tonnes of seamless OCTG. In addition, we have five production lines with an aggregate annual production capacity of 1,430,000 tonnes for the manufacturing of green pipes, which are semi-finished pipes that can be further processed into end-products. We have expanded our hot-rolling OCTG pipe production capacity and pipe threading capacity with the construction of production facilities in Thailand and additional production facilities in China. We ceased the operation of production line in Houston following the disposal of our production facilities, including land, equipment and related permits and licenses, held by Houston OCTG to Southern Tube LLC in November 2012.

We believe that we have a strong reputation in the OCTG industry in China and have been building a growing reputation internationally. We distinguish ourselves by the quality of our products, our customer-oriented research and development capabilities, our long-standing and strong customer relationship, our experienced management team, our ability to timely meet customers’ production requirements, and the quality of our after-sales support. We strive to provide our customers located in China with on-site support that includes engineering assistance to address any technical difficulties that may arise during the installation or operation of our products.

We have grown significantly since our inception until 2009. However, our business was adversely affected in 2009 and 2010 by decreased demand for our products resulting from anti-dumping and countervailing duties imposed on Chinese OCTG products by the United States government, the worldwide economic crisis and oversupply in the domestic PRC market. Our business prospects and financial results improved in 2011, primarily due to increases in both the sales of non-API and API products, but worsened in 2012 due to negative trends in sales volume. In 2010, 2011 and 2012, our net revenues were $470.5 million, $686.1 million and $561.3 million, respectively. We had net losses of $132.8 million, $76.8 million and $89.9 million in 2010, 2011 and 2012, respectively.

Our industry

Overview of seamless OCTG

OCTG refers to a group of pipe and other tubular products used in the exploration, drilling and extraction of oil, gas and other hydrocarbon products. OCTG mainly consist of casing, tubing and drill pipes. Unless otherwise indicated, discussions relating to OCTG in this annual report are limited to these three types of OCTG:

·Casing. Casing pipes serve as the structural retainer for the walls of oil and gas wells, or wellbore. Casing pipes are ordinarily produced with outside diameter sizes of 114.3 mm to 508.0 mm. Casing pipes are inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore.

·Tubing. Tubing pipes are steel tubes suspended inside casing pipes that are used to convey oil or gas to the surface. Tubing pipes typically have diameters of 60.3 mm to 114.3 mm.

·Drill pipes. Drill pipes are pipes used to drill wells. Drill pipes are the conduit between the wellhead motor and the drill bit. Drill pipes, typically around nine meters in length, are screwed together to form a continuous pipe extending from the drilling rig to the drill bit at the bottom of the well. Rotation of the drill pipe, and the resulting rotation of the drill bit, causes the bit to bore through the rock formation. Drill pipes are reusable and not considered regular consumables.

Two basic processes are used in the manufacturing of OCTG. The seamless process involves heating a solid round bar of steel, or billet, cross-rolling or piercing the heated billet to produce a short hollow shell, then elongating and sizing the shell into a finished tube. OCTG manufactured through this process are normally referred to as seamless OCTG. The other process is a welded process, in which tubes are produced from a piece of flat steel, either coil or strip, that is formed into a tubular shape through rolling. Seamless OCTG are generally considered to represent a higher value product compared to OCTG produced by the welded process due to the higher strength of seamless OCTG and its ability to operate under more difficult operating environments.

Our products

Our products are key components in the oil and natural gas drilling and extraction process and are widely used in oil and gas wells in major oilfields throughout China and increasingly in overseas oil fields. The drilling process involves drilling a well to connect the oil or gas layer to the surface by casing and tubing. As the depth of the oil or natural gas layer varies from several hundred to several thousand meters, the oil extraction process requires special casing designed for the depth of the extraction. In addition, the tubing must have a high degree of precision uniformity and tensile strength in order to withstand ground pressure, external and internal pressure and the pull force at the wellhead during the extraction process. The following diagram is an illustration of a typical oil well.

We manufacture a broad range of seamless OCTG, which can be subdivided into API products and non-API products.

·API products . These are manufactured in accordance with a standard which is considered to be the basic or minimum standard that must be met for oilfield equipment. API is the primary trade association of the oil and natural gas industry in the United States and promotes the standardization of oilfield equipment by setting and maintaining more than 500 standards and recommended practices. The API standard is a benchmark standard, and API products are produced according to the API specifications.

·Non-API products . These are custom-made products. In addition to meeting API standards, non-API products are made with qualifications or specifications developed to meet customers’ special needs, such as higher strength, higher corrosion resistance or premium connectors. Non-API products are generally made to a higher standard than API products, and therefore more stringent technical standards and complex manufacturing techniques are required.

The table below sets forth our net revenues attributable to the two product categories for the periods indicated.

	For the year ended December 31,
	2010		2011		2012
API net revenues (in thousands)	$	277,290	$	446,223	$	400,622
Sales volume (tonnes)	271,986		391,088		357,530
Average sales price	$	1,020	$	1,141	$	1,121
Non-API net revenues (in thousands)	$	70,143	$	144,766	$	90,161
Sales volume (tonnes)	37,543		72,358		54,369
Average sales price	$	1,868	$	2,001	$	1,658

We manufacture three major types of seamless OCTG, namely casing, tubing and drill pipes, all of which are used extensively in the oil and gas industries. The three major types of OCTG that we manufacture are described in detail below.

·Casing . Casing is a large-diameter pipe that lines the wellbore. Casing is used to prevent the wall of the wellbore from collapsing and allows drilling fluid to circulate and extraction to take place. The following diagram illustrates different types of casing used in the extraction process:

There are several layers of casing: surface casing, intermediate casing and production casing. Surface casing is used to protect the well from contamination in the shallow water and gas layers. It also supports the wellhead equipment and sustains the weight of the other layers of casing. Intermediate casing is used to isolate different layers of pressure to facilitate normal circulation of drilling fluid and also to protect the production casing. Intermediate casing also facilitates the installation of blow-out preventors, anti-leakage devices and tailpipes in the well. Production casing, also called the oil string, is the conduit through which oil and gas pass from the reservoir to the surface. Production casing also protects the well and separates fluids into various layers.

·Tubing . Tubing is a pipe used for the transportation of crude oil and natural gas from the oil or gas layer to the surface after drilling has been completed. Tubing must be made to withstand the pressure generated from the extraction process. Tubing is manufactured in the same way as casing, except that an additional process known as “upsetting” is applied to thicken the pipes.

·Drill pipes . Drill pipes are steel tubes fitted with threaded ends and are used to connect the rig surface equipment with the bottomhole assembly. Drill pipes are also used to transport drilling fluid to the bit and to raise, lower and rotate the bottomhole assembly and the bit. Drill pipes must be manufactured to withstand severe external and internal pressure, distortion, bending and vibration.

In addition to the above types of seamless OCTG, we also produce line pipes, also known as liners, which are a special type of casing pillar that extends to the wellhead. Line pipes can be broadly divided into drilling liners and oil extraction liners. We classify our line pipe products as API products. We also produce green pipes, which are semi-finished pipes that we further process into our end-products. We sell green pipes to customers upon request. In 2009, 2010 and 2011, we sold steel billets and other unfinished products to meet our customers’ production requirements. We also sold iron ore pellets in 2009 and 2010.

Marketing and sales

Our marketing and sales approach varies according to the targeted market. China is currently our most important market. For sales in China, we mainly engage in direct sales. We have also established four representative offices in Daqing, Changqing, Xinjiang and Sichuan oilfields in China. Our representative offices, except the representative offices in Daqing and Houston, have field engineers who provide on-site technical support to our customers. Our engineers can also be sent to other oilfields when our customers request on-site technical support. We also encourage our on-site technicians to promote our products, especially our non-API products that compete with imported non-API products. Our customers typically conduct a quality review to ensure the integrity and stability of our operations before doing business with us.

In order to offset the significant decline in business from North America due to countervailing duties on seamless pipes made in China, we will continue to increase sales and marketing efforts in other international markets. Through our subsidiary, Houston OCTG, we have been actively pursuing customers in Central and South America. In February 2010, we also acquired WSP Pipe, a company incorporated in the Thai-Chinese Rayong Industrial Zone, Thailand, which is not subject to countervailing duties imposed by the U.S. government. We have been successful in our penetration efforts, tapping into new markets and securing new customers in Northern and Western Africa, particularly in Algeria and Nigeria. In 2010, we secured contract wins worth a total of approximately $91.8 million to sell our products to Venezuela, which represents further penetration into the South American market. We secured the contract wins through bidding for open tenders announced by the Venezuelan government. In 2011, our success in penetrating the South American market continued as we secured new contract wins for sales of our products to Ecuador. We are qualified to sell products to certain major oil companies in the Middle East and have begun providing casing and drill pipe to them. In 2012, we secured contract wins for sales of our products in Oman, which represents our penetration into the Middle Eastern market. We currently have an extensive customer base covering more than 25 countries and regions.

31

For international sales, we currently rely mainly on distributors in major international markets that purchase products from us and then sell our products to operators of oil and gas fields. As part of our after-sales support function, we send our technicians overseas to our customers’ locations upon request. In 2010, 2011 and 2012, international sales accounted for approximately 37.3%, 46.8% and 44.4%, respectively, of our net revenues.

Customers

We have adopted a customer-oriented approach to sales and marketing and strive to provide high-quality customer support, including after-sales support. We believe our approach has enabled us to establish long-standing customer relationships with a broad customer base across major oilfields in China, including Daqing, Changqing, Xinjiang, Sichuan and Yanchang oilfields. The Daqing, Changqing, Xinjiang and part of Sichuan oilfields are operated by CNPC. In 2012, we were one of the three largest OCTG suppliers to CNPC and one of the two China-based non-API suppliers to Sinopec.

We typically extend our PRC customers credit with terms between 60 to 90 days. The credit terms are determined based on, among other things, prevailing market conditions, the size of the companies, their profitability, transaction volume, payment history, industry information on their credit worthiness and duration of their business relationship with us. We usually give credit to customers who have long-standing business relationships or large volume transactions with us.

Our overseas customer base covers a wide geographical area and our products are used in oilfields in North and South America, the Middle East, Asia, Africa and Russia. For overseas customers and distributors, payment is usually made through telegraphic transfer or a letter of credit that is issued prior to the shipment of products. We extend credit up to 180 days to certain large customers who have established long-standing business relationships with us.

Sales of our products are typically conducted either through purchase orders or sales contracts with a term of less than six months. We typically offer a warranty on our products for up to one year. During the warranty period, we will repair or replace faulty products. In 2010, 2011 and 2012, we incurred warranty costs of $45,000, $2.5 million and $5.6 million, respectively.

Our customers of other products are typically domestic manufacturers of steel products, and we only sell other products at our customers’ request. Sales of our other products are made via purchase orders placed by our customers. We sometimes enter into short-term sales contracts with terms of 60 to 90 days with our customers pursuant to which we sell our products at a fixed price during the term of each contract. We do not typically offer a warranty on our sale of other products.

In 2010, 2011 and 2012, sales to our five largest customers accounted for approximately 46.5%, 69.5% and 63.8%, respectively, of our net revenues. Sales to CNPC accounted for 20.2%, 34.2% and 39.8% of our net revenues for the years ended December 31, 2010, 2011 and 2012, respectively. Sales to PDVSA Services B.V. accounted for 11.1%, 22.3% and 6.2% of our net revenues for the years ended December 31, 2010, 2011 and 2012, respectively. The following table lists our five largest customers for the periods indicated.

Pricing policy

Our products are not currently subject to any price controls or regulations by PRC government authorities. The government does not participate in our pricing decisions. In determining product pricing, we primarily consider the following factors: estimated overall market price level, costs, brand name and customer recognition of competing products. We generally set our prices according to the market prices at the relevant markets. Prices for our API products in the PRC domestic market are generally set based on the prevailing market prices, which are usually the prices at which CNPC purchases from its major suppliers. Our export prices are typically higher than our domestic prices. Our export prices fluctuate depending on local market conditions, exchange rates and other factors. The prices of our OCTG are competitive compared to those charged by our international competitors. We generally set prices of our other products according to the market prices at the relevant markets. In determining product pricing, we primarily consider the following factors: estimated overall market price level, costs, brand name and customer recognition of competing products.

Logistics

We usually deliver our finished products to customers in China by train or by truck in circumstances requiring urgent delivery. Our deliveries overseas are primarily made by ship. We have engaged a number of overseas shipping agents to transport our finished products overseas. For short-distance delivery of our products, for example, from our site to train stations, we have entered into a transportation framework agreement with Wuxi Quanhua Material Co., Ltd., or Quanhua Material, a related party. Under this agreement, Quanhua Material agreed to provide transportation services to us for a fee that is negotiated based on the prevailing market price. This agreement initially expired on December 31, 2011 and has been renewed on an annual basis for an additional year.

Wuxi has a well-developed transportation infrastructure and an easy access to port facilities and railroads. Wuxi is located on both the Shanghai-Nanjing expressway and the Shanghai-Nanjing rail line. The Hangzhou-Beijing Grand Canal also flows through Wuxi. We have a 20,000-square-meter logistics center in Wuxi. We procure our raw materials from Wuxi and other provinces in China. Raw materials from Wuxi are usually delivered to our facilities by truck or barge, while raw materials from other provinces are usually delivered to us by train or ship.

Manufacturing

The following diagram illustrates our manufacturing process.

OCTG Manufacturing Process

Hot-rolling production process. Our production process begins with the transportation of round steel billets from our suppliers to our production plants in Wuxi. Typically, these round steel billets have diameters of between 180 mm to 330 mm, weigh approximately 442 kg to 481 kg and have a length between 1.8 meters to 4.5 meters. After passing quality inspection, round steel billets are processed and manufactured into green pipes, which are semi-finished pipes. Green pipes are further processed into final products.

Round steel billets can be manufactured into green pipes through either the hot-rolling process or the cold-draw process. For the hot-rolling process, the round steel billets are first heated to the required temperature, then a hole is pierced length-wise through each individual round steel billet. The pierced round steel billet then undergoes an elongation process to round the pierced hole into the required circular shape. After that, it is reheated to standardize the durability of each pipe through a process called “stretch reducing.” For the cold-draw process, the round steel billets are similarly heated and a hole is pierced, but the resulting steel pipe is elongated and shaped through a cold-draw process that uses a mold. The pipes are then straightened and cut into standard lengths of 9.3 meters to 13 meters. Finally, the pipes are subject to various inspections, including size inspections, surface inspections, and nondestructive and hydrostatic tests, before being classified as green pipes or line pipes.

Tubing and casing production process. For the manufacture of tubing, green pipes undergo an “upsetting” process to thicken the walls of the pipes. Apart from this step, the manufacture of tubing and casing is identical. First, green pipes are threaded on each end. The threading is then inspected and, if necessary, rethreaded to ensure that the thread accurately connects to the coupling. Next, the tubing and casing are strengthened by surface treatment and are subject to various inspections, including drifting and hydrostatic tests before they are coated and packaged into tubing and casing. Tubing and casing are manufactured in our threading lines.

Drill pipe production process. In order to produce drill pipes, green pipes are initially “upsetted” to thicken the walls. Next, the pipes are threaded and receive a strength-enhancing copper plating, after which a non-destructive test is conducted. The pipes are then welded to tool joints. The drill pipes then undergo weld heat treatment and a weld finishing process to remove welding stress. Various testing, including a hardness test, pressure test and non-destructive test is then carried out on the finished drill pipes before final coating and packaging. Drill pipes are manufactured in our drill pipe production line.

(1)Comparison of actual output against annual production capacity is not meaningful as our annual production capacity is calculated using an estimated product mix for each production line, which may differ from the actual product mix manufactured from the production line.

(2)We operated these production lines at Jiangsu Fanli. Following the disposal of our equity interest in Jiangsu Fanli in 2010, we ceased the operation of these production lines.

(3)In February 2012, we ceased production of the No. 4 threading line and its equipment was transferred to WSP Pipe. In December 2012, the new threading line began production in Thailand.

In 2010, we expanded our production capacity by introducing four new threading lines, which increased our aggregate annual production capacity by 420,000 tonnes to 1,344,000 tonnes. In 2010, Houston OCTG completed the construction of a pipe threading line with an annual capacity of 120,000 tonnes while Bazhou Seamless completed the construction of three pipe threading lines with an annual capacity of 100,000 tonnes each.

In May 2010, Liaoyang Seamless completed the construction of a hot-rolling OCTG pipe production line with an annual production capacity of 300,000 tonnes. In October 2011, Bazhou Seamless completed the construction of a pipe heat treatment production line with an annual production capacity of 200,000 tonnes.

In April 2011, Bazhou Seamless completed the construction of a hot-rolling OCTG pipe production line with an annual production capacity of 500,000 tonnes. In April 2011, Houston OCTG completed the construction of a pipe heat treatment production line with an annual production capacity of 100,000 tonnes.

In the second half of 2011, we completed construction of an OCTG pipe manufacturing and sales facility at WSP Pipe in the Thai-Chinese Rayong Industrial Zone in Thailand. The first of two hot-rolling production lines with a production capacity of 60,000 tonnes per year commenced trial production in May 2011, whereas the second hot-rolling production line with a production capacity of 120,000 tonnes per year was completed and commenced trial production in September 2011. We also completed the construction of a new threading line with an annual production capacity of 50,000 tonnes at WSP Pipe in October 2011.

We ceased the operation of our production line in Houston following the disposal of our production facilities, including land, equipment and related permits and licenses, held by Houston OCTG to Southern Tube LLC in November 2012. In December 2012, we completed the construction of a new threading line with an annual production capacity of 100,000 tonnes in Thailand.

Suppliers of raw materials

The major raw materials used in our products are round steel billets of various steel grades and green pipes, which are primarily sourced within China. To ensure a steady supply of round steel billets, we have entered into two long-term arrangements for the supply of round steel billets. In December 2006, we entered into a five-year cooperation agreement with Wuxi Xuefeng Steel Co. Ltd., or Wuxi Xuefeng, under which Wuxi Xuefeng was committed to supply us with 300,000 to 600,000 tonnes of round steel billets per year. The purchase price was subject to the parties’ periodic negotiations. This agreement expired in 2011 and going forward, we expect to fulfill our requirements for round steel billets through individual purchase orders from Wuxi Xuefeng on an as needed basis.

36

In July 2008, we acquired Mengfeng, a manufacturer of crude steel billets with a designed annual capacity of 600,000 tonnes to stabilize the supply, quality and cost of our raw materials. However, we stopped production at Mengfeng since the second half of 2011 as we are currently able to obtain raw materials at lower costs. Additionally, in April 2009, we, together with two unrelated individuals, established Chaoyang Seamless in Chaoyang, Liaoning Province, China. We held a 51% equity interest in Chaoyang Seamless, through which we acquired tangible and intangible assets from a sponge iron and steel billet company in Liaoning province. The purpose of this investment was to further ensure a steady supply of raw materials for our growing OCTG manufacturing capacities in China, especially our OCTG production lines in northeastern China. In January 2012, we entered into an agreement with a third party to transfer our entire 51% equity interest in Chaoyang Seamless for nominal cash consideration. The disposal transaction was completed in January 2012. We expect to purchase raw materials from Chaoyang Seamless in the future.

Historically, we relied on third-party green pipe suppliers and subcontractors to supply us with green pipes for our production needs, which was subject to fluctuations in market supply. Starting from 2006, we have significantly reduced our reliance on green pipe suppliers by expanding our in-house manufacturing capabilities of green pipes. As of December 31, 2012, we had five hot-rolling production lines capable of producing 1,450,000 tonnes of green pipes. Our green pipe production facilities are located in Wuxi, Jiangsu Province, Liaoyang, Liaoning Province, Kuerle, Xinjiang Autonomous Region and the Thai-Chinese Rayong Industrial Zone, Thailand. Our in-house production of green pipes allows us to monitor the quality of our green pipes without having to rely on the quality assurances of other manufacturers or suppliers. By producing green pipes ourselves, we have also streamlined our in-house production process and shortened the production cycle of our OCTG.

Expenditures on raw materials accounted for 73.4%, 78.3% and 77.5% of our cost of revenues in 2010, 2011 and 2012, respectively. In 2010, 2011 and 2012, purchases from our five largest suppliers accounted for approximately 29.9%, 29.0% and 45.8%, respectively, of our total raw material purchases.

Quality control and certifications

We have implemented a stringent quality control system at all stages of our production process. In order to ensure that our raw materials meet the required quality standards for production, we have implemented a set of procedures for the selection of our suppliers, following guidelines set forth in a quality control handbook issued by API. We have adopted a series of quality control tests to inspect all raw materials supplied to us and our projects in different stages of the production process, including the following:

·Size and surface inspection. Our quality assurance staff inspects the size and surface of the tubes to ensure that the tubes meet the required standard during the tube manufacturing process.

·Non-destructive test. This test is conducted to ensure that no damage occurred to the tube during the upsetting, heat treatment and hot straightening treatments. For the blind areas at the end of the pipes, a magnetic power detectoscope is used to conduct the test. If we find damage within the pipe during the course of this test, our quality assurance staff will further investigate the area with a portable ultrasound detectoscope.

·Thread inspection. This test is conducted by our production staff by physically examining the thread after the threading stage of the production process to ensure that the thread accurately conforms to the required parameters.

·Hydrostatic test. In this test, the pipes are rolled onto a hydrostatic testing machine where water is pumped into the pipes to ensure that the pipes can withstand the requisite internal pressure and to confirm that there is no leakage.

·Drifting test. This test is conducted to inspect the straightness of the pipes and to determine if any protrusions exist along the inner walls.

·Physical and chemical analysis. This test analyzes the chemical composition, mechanical performance and metallographic structure of the pipe materials.

·Hardness and pressure test. The pipes are physically tested through a weld finishing test and hardness test to ensure that the pipes can withstand the requisite external pressure and exhibit the required hardness before final coating.

37

We also conduct quality control tests on our finished products. The pipes are subject to physical checks by our quality assurance staff to ensure that there are no visible defects and that all finished pipes accurately conform to the intended parameters and lengths.

We have a team of over 300 quality assurance staff equipped with advanced testing equipment. We also provide regular training to our production staff and have established a set of mandatory internal procedures and standards.

We have obtained certificates of registration from API certifying that our quality management system was in compliance with the ISO 9001 and API specification Q1 quality system standards in February 2002 and ISO/TS 29001 in December 2004. These certificates of registration are effective from the date of registration and have no expiration dates, provided that we continue passing the annual inspections by API. The scope of these registrations and the approved quality management systems apply to the manufacture of casing, tubing, line pipes and drill pipes, threading of tool joints and rotary-shouldered connections.

We further obtained certificates of authority to use the official API monogram on our manufactured products under the conditions of API Specification 5CT, API Specification 5D and API Specification 5L in February 2002 and API Specification 7 in February 2005. These certificates are subject to periodic inspection by API and must be renewed every three years. The expiration date of our current API certificates is May 2014.

In addition, we have obtained various industrial awards or certificates. In January 2008, WSP China was awarded “AAA” grade supplier certification by Daqing Oilfield Materials and Equipment Group, which procures production materials and equipment for Daqing Oilfield Company Limited, or Daqing Oilfield, a subsidiary of PetroChina Company Limited, the largest oil and natural gas producer in China. This certification means WSP China’s products and services meet the high standards set by Daqing Oilfield for suppliers.

Competition

We face competition in the domestic and international markets in which we operate. We believe we differentiate ourselves from our competitors and capture market share both in the domestic and international markets through our sales network, pricing strategies, quality and variety of our products, response time to customers’ specific demands and our ability to provide custom-made products. Furthermore, maintaining a balance of domestic sales and exports also provides us with the flexibility to reallocate sales to the markets with strong demand.

The PRC seamless OCTG market is dominated by a few major steel producers with a large number of small producers competing for the remaining small portion of the market. We face competition mainly from top producers who have succeeded in establishing a strong brand name with oil companies. Our major competitors in the PRC seamless OCTG market include Tianjin Pipe (Group) Corporation, Shanghai Baosteel Group Corporation and Pangang Group Chengdu Iron & Steel Co., Ltd. Among these major competitors, we are the only one specializing in seamless OCTG products, while the others also produce welded OCTG or non-OCTG products. Many of our competitors are state-owned enterprises which may have greater resources and better brand recognition than we do.

The competitors in our export markets include leading seamless pipe producers in the world, particularly those in Argentina, Japan, the United States, France and Russia. Our international competitors include JFE Steel Corporation in Japan, US Steel in the United States, Tenaris in Argentina, Vallourec & Mannesmann Tubes in France, TMK in Russia and Sumitomo in Japan.

Intellectual property rights

We recognize the importance of protecting and enforcing our intellectual property rights by actively seeking legal protection for our products and proprietary information through patents, trademarks and technical know-how. See “Item 5. Operating and Financial Review and Prospects—C. Research and Development” for more information relating to our patents.

As of the date of this annual report, we had 132 patents and 67 pending patent applications in China, which include both utility model and invention patents. Most of our patents and patent applications relate to the manufacture of our non-API products. Specifically these patents deal with the production of specialized connectors, couplings and casings, and the production of our non-API products is substantially dependent on these patents. We own or have applied for patents to protect technologies that we believe are significant to our business. As with patent rights in most other jurisdictions, a patent holder in China has the right to exclude others from using and otherwise exploiting the patented technology within China without a license from the patent holder. Most of our patents cover utility models and have terms of ten years. Five of our patents cover inventions and have terms of 20 years. As we only hold PRC patents, if third parties manufacture and sell products using our technology outside China in competition against us, we may not have a legal cause of action against them.

38

In addition, we maintain trademarks for the name “WSP” in Saudi Arabia, Indonesia, Colombia and Hong Kong. Our trademarks registration in Hong Kong covers our logos. We also have pending trademark applications in Malaysia, the United States, Canada and several other countries. As our brand name is becoming more recognized in the OCTG market, we are working to increase, maintain and enforce our rights in our trademark portfolio, the protection of which is important to our reputation and branding. We have one registered domain name. We have also entered into confidentiality agreements with our employees and business partners to protect our confidential information and know-how.

Environmental and safety matters

We believe we have been in substantial compliance with national and local environmental laws and regulations in China. We have installed waste treatment facilities and implemented waste treatment procedures to ensure that waste produced during our production processes is discharged in compliance with applicable laws and regulations. We have designated staff to handle solid waste and its disposal by selling re-usable steel scraps and defective pipes and disposing of other waste to waste collection companies. In addition, we have installed two sets of jet cloth filters to filter the oxidized dust generated from hot-rolling pipe production and pipe processing.

In order to handle the waste water generated from our production lines for hot-rolling pipe production and pipe processing, we have installed three waste water disposal systems. Processed waste water is recycled and is not discharged. Emulsified liquid waste generated in pipe processing is delivered to qualified companies for disposal.

We have installed improved ventilation systems for four of our threading lines by installing an axial-flow machine, increasing the number of air-vents and enlarging ventilation windows. These measures have contributed to an improvement in air quality and lower temperatures at our production facilities. In addition, in order to reduce the negative impact of our operations on the environment, we use natural gas in our hot-rolling pipe production lines for each stage of our hot-rolling production process. The burning of natural gas emits minimal pollutants when compared to oil and coal.

The local environmental regulatory authority of Wuxi, Jiangsu Province conducts regular inspections of our operations to ensure that we are in compliance with all applicable domestic environmental laws and regulations. We currently comply with the ISO 14001:2004 environmental standards. ISO 14001 specifies the requirements for an environmental management system, which helps to minimize operational impact on the environment.

Since pollution caused by our production activities is much less than those of larger-scale iron and steel operations, we currently do not perform any research and development on environmental matters.

We have not been subject to any fines or legal action involving non-compliance with any relevant environmental regulations, nor are we aware of any threatened or pending action by any environmental regulatory authority in any location where we operate our business.

Insurance

We maintain property insurance with respect to our operations that covers general property, plants and machinery, and shipping and transportation. In addition, we have limited product liability insurance that covers our sales in North America by Houston OCTG. A large number of our product liability insurance policies for products sold by Houston OCTG have reached their maximum payouts. We are currently in the process of negotiating this policy. However, we do not maintain product liability, business interruption or key-man insurance in China. We believe that our insurance coverage is customary for similar operations in our industry in China. However, we cannot assure you that our existing insurance policies are sufficient to protect us from all losses and liabilities that we may incur.

Regulations

This section sets forth a summary of the most significant regulations or requirements that affect our business activities in China or our shareholders’ right to receive dividends and other distributions from us.

Regulations on seamless OCTG manufacturing and sales businesses

The PRC government maintains a Catalogue for the Guidance of Foreign Investment Industries, or the Catalogue, which was issued jointly by the National Development and Reform Commission, or the NDRC, and the Ministry of Commerce. The Catalogue distinguishes between encouraged and discouraged industries, with discouraged industries being further classified into those where foreign investment is restricted and those where foreign investment is prohibited. OCTG manufacturing and sales is neither a discouraged nor an encouraged business.

Under the PRC law, operators of seamless OCTG manufacturing and sales businesses are not required to obtain any special licenses from government agencies, other than regular business licenses and other permits that must be held by every business entity located in China.

Regulations on environmental protection

The OCTG industry is not considered as a heavy pollution industry by the PRC State Environmental Protection Authority. However, we are still subject to a variety of governmental regulations related to environmental protection. The major environmental regulations applicable to us include the Environmental Protection Law of the People’s Republic of China, the Water Pollution Prevention Law of the People’s Republic of China, the Atmospheric Pollution Prevention Law of the People’s Republic of China, the Environmental Noise Pollution Prevention Regulations of the People’s Republic of China, the Environmental Impact Assessment Law of the People’s Republic of China and the Regulations Governing Environmental Protection in Construction Projects. Also, general environmental regulations relating to noise and the treatment of industrial waste are applicable to our operations.

All phases of our operations are subject to environmental regulations and discharge standards promulgated by government agencies in China. Before we may begin project development and production, we must comply with environmental regulations and standards. Environmental regulations set forth limits and prohibitions on spills, releases or emissions of various substances produced in association with certain processing and manufacturing operations. A breach of any regulations may result in imposition of fines and penalties and even curtailment or suspension of our operations. Furthermore, future changes in environmental laws and regulations could occur that result in stricter standards and enforcement, larger fines and liability, and increased capital expenditures and operating costs, which could have a material adverse effect on our financial condition or results of operations.

Regulation on PRC iron and steel industry

According to the Catalogue, steel production is neither a discouraged nor an encouraged business. In July 2005, the NDRC issued the Development Policy for the Iron and Steel Industry, or the Iron and Steel Policy, outlining the government’s comprehensive policy for the iron and steel industry. The Iron and Steel Policy sets forth the government’s guidance and regulations on all aspects of the iron and steel industry in China, including resource and equipment utilization, regional concentration of outputs, quality improvements, technological innovation, investment management and industry consolidation. The Iron and Steel Policy stipulates minimum plant size, capacity investment and technologies to be used in the industry. Pursuant to the Iron and Steel Policy, government approvals are required for the establishment of new steel plants and their upgrades, among other things. The Iron and Steel Policy also provides that as a matter of “general principle,” foreign investors may not own controlling stakes in PRC enterprises engaging in the iron and steel business. For violators of the policy, the Iron and Steel Policy provides various administrative punishments, including withholding manufacturing permits, environmental impact evaluation reports and waste discharge licenses.

In July 2008, WSP China acquired Mengfeng, a company located in Inner Mongolia, China. Mengfeng has been approved as a seamless steel pipe manufacturer by the Hohhot Municipal Commission of Development and Planning. However, Mengfeng has already built a seamless steel pipe production line which is currently in trial production. Because Mengfeng is part of our integrated OCTG manufacturing business and its steel billet outputs are primarily used for our production of OCTG rather than for sale to any third party, our management believes that WSP China’s ownership in Mengfeng is not in violation of the Iron and Steel Policy. However, there are substantial uncertainties regarding the interpretation and application of the Iron and Steel Policy. Accordingly, there can be no assurance that the PRC regulatory authorities, in particular the NDRC, will not in the future take a view that is contrary to the view of our management. If the PRC government determines that WSP China’s ownership in Mengfeng does not comply with the PRC government restrictions on foreign investment under the Iron and Steel Policy, we could be subject to severe penalties.

Regulations on negotiable instruments

Pursuant to the PRC Negotiable Instruments Law, adopted by the Standing Committee of the National People’s Congress on May 10, 1995 (as amended on August 28, 2004) and various PRC regulations, negotiable instruments including bank acceptance notes and commercial acceptance notes shall be issued in good faith and based on actual underlying transactions.

Under the PRC Negotiable Instruments Law and other relevant PRC regulations, administrative and criminal liabilities may apply to those who:

·counterfeit negotiable instruments;

·knowingly draft, sell or transfer counterfeit negotiable instruments;

·issue cheques that cannot be honored either due to insufficient funds or incorrect signature or seal;

·issue bills of exchange or promissory notes without reliable sources of funds for the purpose of obtaining money through fraud;

·make false entries on bills of exchange or promissory notes when issuing such instruments for the purpose of obtaining property or money through fraud;

·use negotiable instruments of others without authorization, or use overdue or invalid negotiable instruments for the purpose of obtaining property or money through fraud; or

·commit one of the abovementioned acts as the payer, in conspiracy with the drawer or holder of the negotiable instrument.

In addition, those who violate the PRC Negotiable Instruments Law and cause damages to others may be subject to civil liabilities.

In 2010, 2011, 2012 and to date in 2013, we entered into certain bill financing arrangements which were not in compliance with the general principles under the PRC Negotiable Instruments Law. See “Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Bill financing.”

Regulations on foreign currency exchange

Pursuant to the Foreign Currency Administration Rules promulgated in 1996 and amended in 2008 and various regulations issued by SAFE, and other relevant PRC government authorities, Renminbi are freely convertible only to the extent of current account items, such as trade related receipts and payments, interest and dividends. Capital account items, such as direct equity investments, loans and repatriation of investment, require prior approval from SAFE or its local counterpart for conversion of Renminbi into a foreign currency, such as U.S. dollars, and remittance of the foreign currency outside of China.

Payments for transactions that take place within China must be made in Renminbi. Unless otherwise approved, PRC companies must repatriate foreign currency payments received from abroad. Foreign-invested enterprises may retain foreign exchange in accounts with designated foreign exchange banks subject to a cap set by SAFE or its local counterpart. Unless otherwise approved, domestic enterprises must convert all of their foreign currency receipts into Renminbi.

Regulations on dividend distribution

The principal laws and regulations governing dividend distributions by wholly foreign-owned enterprises and Sino-foreign equity joint ventures include:

·Wholly Foreign-Owned Enterprise Law (1986), as amended in 2000;

·Wholly Foreign-Owned Enterprise Law Implementing Rules (1990), as amended in 2001;

·Sino-foreign Equity Joint Venture Enterprise Law (1979), as amended in 2001; and

·Sino-foreign Equity Joint Venture Enterprise Law Implementing Rules (1983), as amended in 2001.

41

Under these laws and regulations, wholly foreign-owned enterprises and Sino-foreign equity joint ventures in China may pay dividends only out of their accumulated profits, if any, as determined in accordance with the PRC accounting standards and regulations. Additionally, these foreign-invested enterprises are required to set aside 10% of their after-tax profits based on the PRC accounting standards each year, if any, to fund their general reserve fund, until the accumulative amount of such reserves reaches 50% of their registered capital. These reserves are not distributable as cash dividends. Wholly foreign-owned enterprises are also required to allocate a portion of their after-tax profits, as determined by the board of directors, to its staff welfare and bonus funds, which may not be distributed to equity owners.

In addition, dividends we pay to our non-PRC shareholders may be subject to a 10% withholding tax. After FSHL was qualified as a tax resident company in the Hong Kong Special Administrative Region in 2009, a withholding tax at 5% is applicable on dividends paid to FSHL. See “Item 10 Additional Information—E. Taxation—People’s Republic of China taxation.”

C.     Organizational Structure

We hold our interest in the operating subsidiaries indirectly through our wholly-owned intermediate holding company, FSHL, a company incorporated in the British Virgin Islands.

The following discussion of our financial condition and results of operations is based upon and should be read in conjunction with our consolidated financial statements and their related notes included in this annual report. This report contains forward-looking statements. See “Item 5. Operating and Financial Review and Prospects—G. Safe Harbor.” In evaluating our business, you should carefully consider the information provided under the caption “Item 3. Key Information—D. Risk Factors” in this annual report. We caution you that our businesses and financial performance are subject to substantial risks and uncertainties.

A.     Operating Results

Overview

We are a leading Chinese manufacturer of seamless OCTG, including casing, tubing and drill pipes used for oil and natural gas exploration, drilling and extraction. We sell our products in both domestic and international markets. We offer a comprehensive range of seamless OCTG products to our customers. Our product portfolio can generally be divided into API products and non-API products.

In China, we target sales of our products primarily at leading Chinese oil companies. For instance, in 2012, we were one of the three largest OCTG suppliers to CNPC, and one of the two China-based non-API suppliers to Sinopec. In the international markets, we have established an extensive overseas customer base, covering oilfields in North and South America, the Middle East, Asia, Africa and Russia.

We have grown significantly since our inception until 2009. However, our business was adversely affected in 2009 and 2010 by decreased demand for our products resulting from anti-dumping and countervailing duties imposed on Chinese OCTG products by the United States government, the worldwide economic crisis and oversupply in the domestic PRC market. Our business prospects and financial results improved in 2011, primarily due to increases in both the sales of non-API and API products, but worsened in 2012 due to negative trends in sales volume. In 2010, 2011 and 2012, our net revenues were $470.5 million, $686.1 million and $561.3 million, respectively. We had net losses of $132.8 million, $76.8 million and $89.9 million in 2010, 2011 and 2012, respectively. As of December 31, 2010, 2011 and 2012, our annual production capacities of seamless OCTG were 1,344,000, 1,394,000 and 1,404,000 tonnes, respectively.

43

Sales.  In 2009, we began facing challenges in our business prospects resulted from declines in our sales in the United States due to the anti-dumping and countervailing duties imposed on Chinese OCTG products by the U.S. government as well as oversupply condition in domestic market, and these challenges have continued into 2013.  We also face challenges as a result of the global slowdown and uncertainties in our targeted markets, namely China, North America, South America, the Middle East and Central Asia, which have caused project modifications, delays or cancellations, general business disruptions, and delays in, or nonpayment of, amounts that are owed to us from our customers.  In addition, because we depend on a limited number of customers, declines in our major customers’ businesses have also lead to a decline in purchase orders from these customers, which have adversely affected our business.

In light of the above challenges, we have been exploring, on a longer-term basis, to broaden our customer base in international markets such as South America, the Middle East, Central Asia and Africa, which provide opportunities for sales growth.  For example, in South America, we won a mandate from a state-owned oil company in Venezuela for $81.0 million of API and non-API casing pipes, API tubing pipes, line pipes and connectors in June 2011.  In the Middle East, we won a purchase order of $26.5 million for our API tubing pipes and other products in the first quarter of 2012.  We have also developed and launched in 2011 new series of non-API products for commercial use in our efforts to expand in domestic markets such as Xinjiang Autonomous Region, Sichuan Province, Shaanxi Province, Henan Province and Shandong Province, which provide opportunities for sales of higher-margin products. As we continue to face challenges, we will continue to pursue aggressively international and domestic opportunities to increase sales.

Operations.  We have faced challenges in our operations due to overcapacity and production stoppages at some of our production facilities.  Declines in our sales have resulted in a low capacity utilization of our plants in Liaoning Province, Inner Mongolia Autonomous Region and Xinjiang Autonomous Region, and the maintenance of under-utilized facilities has added further pressure to our financial condition.  Our newly completed facilities in Thailand, which commenced commercial production in May 2011, have undergone a period of equipment testing, trial production, efficiency upgrades and personnel training, which caused production delays.  We are also facing challenges in our ability to win additional purchase orders of our products to allow our production facilities to operate at full capacity. The maintenance of these facilities before they reach full utilization imposes significant pressure on our financial and operational conditions.

In light of the above challenges in our operations, we have been scaling down certain projects and downsizing our workforce to bring our production capacity in line with demand for our products, as well as conserve cash to improve our financial condition.  We have disposed of certain assets, including our equity interests in Kuitun Seamless in July 2011 and Chaoyang Seamless in January 2012, and the production facilities held by Houston OCTG in November 2012.  Our production facilities in Thailand became fully operational in the first quarter of 2012.  We are also increasing our efforts in winning purchase orders in our targeted markets in order to increase utilization of our production capacities.  We continue to adopt initiatives that will reduce overcapacity, improve our cost structure and streamline our operating structure in today’s challenging environment.

Financial condition.  We also face challenges in our financial condition due to significant operating losses and working capital deficiencies experienced by us since 2009, and negative operating cash flow experienced by us from 2009 to 2012.  We have relied, and will continue to rely, largely on operating cash flow and short-term borrowings for the working capital needs of our operations.  A significant amount of our short-term borrowings is required to be refinanced, which raises challenges in our ability to continue as a going concern.  Given our reliance on borrowings, we face challenges in our relationship with our lenders and the lenders’ continued support for us is crucial to our operations. Please see “Item 3. Key Information—D. Risk Factors—Risks related to our business—Our financial statements indicate that we have a going concern uncertainty, which could adversely affect our ability to meet our ongoing financing needs and obtain third party financing” and “Item 3. Key Information—D. Risk Factors—Risks related to our business—We and our subsidiaries have been in breach of certain financial covenants under certain loan agreements, which, if not managed carefully, may trigger events of default and accelerated payment and adversely affect our business, financial condition and results of operations.”

In light of these challenges, we have been focused on deleveraging and improving our liquidity and cash flows.  For example, in August 2011, we entered into a syndicated loan facility with eight commercial banks for a total of RMB2.86 billion, which allowed us to replace certain of our existing short-term borrowings with mid-term working capital loans.  We actively communicate with our lenders and inform them on a regular basis of our business conditions in order to maintain a good relationship with them and ensure the availability of their loans to us.  We have also taken various actions to conserve cash, such as reducing working capital requirements in operations through reduction of accounts receivables, inventories and other measures and reducing capital spending through delaying or scaling down certain projects. Specifically, the actions we have taken include:

44

·shutting down non-profitable or under-utilized plants and thereby reducing costs in connection with the maintenance of our production facilities;

·suspending expansion in our production facilities and thereby reducing capital expenditures and working capital;

·disposing certain assets, including our equity interests in Kuitun Seamless and Chaoyang Seamless in July 2011 and January 2012, respectively, and the production facilities held by Houston OCTG in November 2012;

·increasing our efforts in accounts receivable collection, in particular the collection of accounts receivable from overseas customers;

·seeking extension for the payment of current and previous accounts payable; and

·improving our inventory management.

We believe that our actions have alleviated some of the pressure for our cash needs.  As we continue to face high leverage and large near-term maturities, we will continue to take actions to conserve cash.

The following subsection provides a discussion of the economic and industry-wide factors that affect our results of operations, including:

·Demand for seamless OCTG in the domestic and international markets;

·Supply of raw materials;

·Production capacity;

·Pricing; and

·Product mix and geographical distribution.

Overall, demand for our products in our targeted markets and pricing environment affect the revenues we generate from sales of our products while the supply of raw materials is the primary cost factor in our cost of goods sold.  Declines in sales during the past few years have also resulted in under-utilization of our production capacity, which prompted us to scale down our operations.  Product mix and geographical distribution affect our gross margin and operating margin.

Factors affecting our results of operations

Demand for seamless OCTG in the domestic and international markets

Demand for our OCTG products depends significantly on the number of domestic and worldwide oil and gas wells drilled, completed and reworked, as well as the depth and drilling conditions of these wells. The level of such drilling activities in turn depends on the level of capital spending by major oil and gas companies. Capital spending on OCTG used for oil and natural gas exploration, drilling and production activities is driven in part by the prevailing prices of oil and natural gas and the perceived stability and sustainability of those prices. Domestic demand for our products is largely driven by the growth of the oil and gas industry in China. China’s strong demand for oil and gas in recent years has resulted in significant increases in drilling activities in China, leading to a greater demand for seamless OCTG.

Our revenues and net income decreased from 2009 to 2010 due in part to decreases in oil and natural gas prices resulting in from lower demand for our OCTG products. Our revenues and net income increased from 2010 to 2011 due in part to increases in both the sales of non-API and API products. Our revenues and net income decreased from 2011 to 2012 due in part to decreases in both the sales of non-API and API products. From 2010 to 2011, revenues increased by 45.8%, while volume of products sold decreased by 4.0%. From 2011 to 2012, revenues decreased by 18.2% and volume of products sold decreased by 17.6%. In 2010, 2011 and 2012, approximately 37.3%, 46.8% and 44.4%, respectively, of our net revenues were derived from export sales.

45

Since 2005, China has been a net exporter of API OCTG and a net importer of non-API OCTG. North America, Russia and the Middle East are other important seamless OCTG markets. With the existing and conventional reservoirs gradually being depleted, major oil and gas exploration and production companies have significantly shifted their exploration and development focuses to non-conventional deep-water oil sources and non-conventional gas sources in recent years. The shift to more challenging operating conditions have increased demand for high quality seamless OCTG.

However, worldwide developed economies suffered a sharp downturn in late 2008 as looming housing-related asset write-downs at major financial institutions paralyzed credit markets and sparked a serious global banking crisis. The global credit and economic crisis reduced worldwide demand for energy. As a result, after rising steadily for six years to peak at around $147 per barrel in July 2008, oil prices collapsed to the $35 to $50 per barrel range towards the end of 2008. In 2009, oil prices fluctuated between $34 and $80 per barrel. The significant fluctuation in oil and gas prices in 2009 that resulted in lower activity, higher inventories, and the belief that demand will not increase significantly in 2010 as a result of the economic slowdown, has led to rapid and substantial reductions in exploration and production expenditures. In the midst of a weak global economic environment and anti-dumping and countervailing duties imposed by the U.S. government, sales of both our API and non-API products have been adversely affected in 2009. Our marketing and sales strategy at the beginning of 2008 emphasized international sales of OCTG products because of strong overseas demand for high-end, non-API products and higher export prices for API products compared to Chinese domestic market prices for API products. In response to weakening international demand for OCTG products starting from the fourth quarter of 2008, we adjusted our strategy by concentrating on sales of OCTG products to domestic customers. As a result, 61.6% of our net revenues in 2009 were attributable to the domestic market as compared to 34.7% in 2008.

Changes in our sales mix to the Chinese domestic market also helped offset some of our sales decreases in international markets. Domestic average selling prices for our products, especially for API products, remained at low levels despite increasing raw materials costs. Domestic prices for our non-API products remained comparatively higher because our sophisticated proprietary technologies make our products attractive to customers.

In 2010, global demand for our OCTG products remained weak with oil prices recovering slowly amid worries of Europe’s financial crisis and growing oil stockpiles. Sales of both our API and non-API products in 2010 have continued to be adversely affected by the weak global economic environment and anti-dumping and countervailing duties imposed by the U.S. government. As a result of our continued focus on sales of OCTG products to domestic customers due to weakening international demand for OCTG products, 62.7% of our net revenues in 2010 were attributed to the domestic market as compared to 61.6% in 2009.

Towards the end of 2010, U.S. crude oil prices have risen to above $87 a barrel on expectations of higher energy demand and lower U.S. interest rates with the US Federal Reserve taking measures to boost the economy. In the beginning of 2011, U.S. crude oil prices hovered above $100 a barrel amid global economic uncertainty due to concerns that the political upheaval in North Africa and the Middle East may disrupt oil output in the Organization of the Petroleum Exporting Countries, or the OPEC nations. Towards the second quarter of 2011, oil prices traded slightly below $100 a barrel within a narrow range amid signs of slowing global economic growth and growing concerns of European debt crisis. In August 2011, oil prices fell below $80 a barrel amid worries of a bout-dip recession following the downgrade of the U.S. credit rating by the Standard & Poor’s. However, the worsening debt crisis in Europe and the United States as intensified by the escalating unrest in the Middle East caused oil prices to continue trending upward toward the end of 2011 and in the first quarter of 2012. In 2012, worldwide economic growth slowed down due to the global credit and economic crisis, which reduced worldwide demand for energy and resulted in significantly lower crude oil and natural gas prices. In 2013, we expect sales prices in China for our non-API products to remain at current levels for the near term because our products are capable of being used in extreme oil and gas exploration environments. Our customers also recognize the technological advantages of our products, such as our T-series premium connection and anti-corrosion pipes which use our proprietary technologies. Our non-API products have price advantages compared to those products produced by our international competitors because of our lower costs of production, and we provide faster delivery to our international customers than most of our international competitors. See “Item 3. Key Information—D. Risk Factors—Risks related to our business —Declines in domestic and international oil and natural gas prices, or domestic and international exploration, drilling and production activities, would adversely affect our profitability.”

Supply of raw materials

Our primary raw materials consist primarily of round steel billets and green pipes. The prices of round steel billets and green pipes fluctuate in response to global and domestic demand and supply, which have resulted in significant price volatility in recent years. The price of steel has been volatile, but generally trending upward from 2010 to 2012. We have in the past purchased round steel billets directly from suppliers, but have fulfilled and expect to continue to fulfill our requirements for round steel billets through individual purchase orders from Wuxi Xuefeng as Wuxi Xuelang and Anshan Binggong on an as needed basis.

Additionally, in July 2008, we acquired Mengfeng, a manufacturer of crude steel billets with a designed annual capacity of 600,000 tonnes to stabilize the supply, quality and cost of our raw materials. However, Mengfeng has currently stopped production activities due to continued operating losses and is rescheduling its production planning. Additionally, in April 2009, we, together with two unrelated individuals, established Chaoyang Seamless in Chaoyang, Liaoning Province, China. We held a 51% equity interest in Chaoyang Seamless, through which we acquired tangible and intangible assets from a sponge iron and steel billet company in Liaoning province. The purpose of this investment was to further ensure a steady supply of raw materials for our growing OCTG manufacturing capacities in China, especially our OCTG production lines in northeastern China. In January 2012, we entered into an agreement with a third party to transfer our entire 51% equity interest in Chaoyang Seamless for nominal cash consideration. The disposition transaction was completed in January 2012. However, we expect to purchase raw materials from Chaoyang Seamless in the future.

Historically, we purchased green pipes primarily from other manufacturers. In January 2007, we began production of green pipes at our new hot-rolling pipe plant in Wuxi with an annual production capacity of 450,000 tonnes of green pipes. We completed the construction of a hot-rolling pipe production line with an annual production capacity of 300,000 tonnes in Liaoyang in 2010 and a hot-rolling pipe production line with an annual production capacity of 500,000 tonnes in Kuerle in April 2011. In the second half of 2011, we completed the construction of an OCTG pipe manufacturing and sales facility at WSP Pipe in the Thai-Chinese Rayong Industrial Zone in Thailand. The first of two hot-rolling production lines with a production capacity of 60,000 tonnes per year commenced trial production in May 2011, whereas the second hot-rolling production line with a production capacity of 120,000 tonnes per year was completed and commenced trial production in September 2011.

Our production of green pipes allows us to monitor the quality of our green pipes without having to rely on the quality assurances of other manufacturers or suppliers. By producing green pipes in-house, we have streamlined our in-house production process and shortened the production cycle of our OCTG.

Production capacity

We have expanded our production capacity significantly in the past few years. As of December 31, 2010, 2011 and 2012, our production capacities of seamless OCTG were 1,344,000, 1,394,000 and 1,404,000 tonnes, respectively. Our annual production capacity is the maximum production capacity that can be achieved at the optimal level of operations of our production lines, calculated using an estimated product mix for each production line. As of December 31, 2012, our key operating assets included eighteen threading lines and two drill pipe production lines. See “Item 4. Information on the Company—B. Business Overview—Manufacturing.” Our overall capacity utilization rate is not comparable year to year due to the fact that our actual output from each production line reflects the actual product mix produced from a particular line, which differs from estimated product mix because the types of products we actually produce are based on customer specifications. We may increase our production capacity in the future depending on the circumstances.

Pricing

In determining product pricing, we primarily consider factors including projected overall market price levels, costs and customer recognition of competing products. The domestic prices of our API products are generally set based on the prevailing domestic market prices, which are usually the prices at which CNPC, the largest owner of oilfields in China, purchases from its major suppliers. Our export prices are usually set based on the prevailing international market prices, which are typically higher than our domestic prices. The prices of our OCTG are competitive with those charged by our international competitors.

Average sales price for our non-API products increased from 2010 to 2011 primarily due to increased sales of higher priced non-API products in the international markets.  Average sales price for our non-API products decreased from 2011 to 2012 primarily due to increased sales of lower priced non-API products in the domestic market.

47

In 2010, average export prices decreased from 2009, primarily due to sales of lower priced API and non-API products as a result of weakening international market demand. In 2011, average export prices increased from 2010 primarily due to sales of higher priced API and non-API products. In 2012, average export prices decreased from 2011 primarily due to sales of lower priced API and non-API products in the international markets.

From time to time, we have also sold non-OCTG products such as green pipes, which allows us to reduce the stock of our inventory of raw materials or unfinished products in different stages of our manufacturing process. We generally set prices of other products according to the market prices at the relevant markets. In determining product pricing, we primarily consider the following factors: estimated overall market price level, costs, brand name and customer recognition of competing products.

Product mix and geographical distribution

Our gross margin and operating margin are substantially affected by our product mix, particularly with respect to API and non-API OCTG products. Our non-API products are generally non-standard products with customized specifications that are developed to meet special needs, such as improved strength, higher corrosion resistance, improved sealing and premium connectors, among others. Because non-API products typically command a price premium compared with API products, our gross margin and operating margin will increase if a higher percentage of our net revenues are derived from sales of non-API products. Sales of our non-API products as a percentage of net revenues increased from 14.9% in 2010 to 21.1% in 2011, and decreased to 16.1% in 2012, while sales of our API products as a percentage of net revenues increased from 58.9% in 2010 to 65.0% in 2011, and increased to 71.4% in 2012. The following table sets forth sales volume and average sales prices of our API and non-API products for the periods indicated.

	For the year ended December 31,
	2010		2011		2012

Non-API
Sales volume (tonnes)	37,543		72,358		54,369
Average sales price	$	1,868	$	2,001	$	1,658

We generate revenues from both domestic and export sales. Domestically, we are a major player in the seamless OCTG market. In recent years, we have also devoted efforts to expand our export sales and our international presence because export prices are generally higher than domestic prices for the same products and exports provide us with revenue diversification and allow us to build global brand recognition. Revenues from domestic sales accounted for 62.7%, 53.2% and 55.6% of our net revenues in 2010, 2011 and 2012, respectively. Revenues from export sales accounted for 37.3%, 46.8% and 44.4% of our net revenues in 2010, 2011 and 2012, respectively. The increase in export sales as a percentage of total revenues from 2010 to 2011 was primarily due to increased sales of both API and non-API products. We rely mainly on distributors and agents to sell our products to oil and gas fields overseas. In 2011, we increased our sales in overseas market as the overseas markets recover and continued to develop our ability to conduct direct sales overseas. The decrease in export sales as a percentage of total revenues from 2011 to 2012 was primarily due to lower international market demand for our products. The following table sets forth the sales volume and average sales prices of our domestic and export sales for the periods indicated. Our domestic and export sales below also include our sales of non-OCTG products.

Overview of financial results

Net revenues

Our net revenues primarily consist of sales of OCTG products. Our OCTG products fall into two categories, API products and non-API products. Our primary OCTG products consist of tubing, casing and drill pipes. See”—Factors affecting our results of operations—Product mix and geographical distribution” for details on our product mix. We also generate, to a lesser extent, revenues from other non-OCTG pipe products, such as green pipes, which are semi-finished pipes that can be further processed into end-products, as well as iron ore pellets, iron ore billets and other unfinished products. The following table sets forth the net revenues of our API, non-API and other products for the periods indicated. Net revenues are net of business taxes.

	For the year ended December 31,
Net revenues (in thousands)	2010		2011		2012
API	$	277,290	$	446,223	$	400,622
Non-API	70,143		144,766		90,161
Iron ore	31,918		—		—
Others	91,114		95,136		70,514
Total	$	470,465	$	686,125	$	561,297

We have built an extensive customer base, covering customers located in China, as well as in North and South America, the Middle East, Asia, Africa and Russia. Sales of our OCTG products to the South American market increased as a result of our successful penetration into this market and accounted for 25.5% of our export sales in 2012. We determine the geographical market of our net revenues based on the location of the initial purchasers of our products. The following table sets forth the breakdown of our net revenues by geographic market for the periods indicated. See”—Factors affecting our results of operations—Product mix and geographical distribution” for a discussion of our domestic and export sales trends.

Cost of revenues

Our cost of revenues consists primarily of our manufacturing costs adjusted for changes in inventory. Our manufacturing costs primarily include the costs of raw materials used to manufacture our products, most significantly, green pipes and round steel billets. Green pipes have accounted for a significant portion of our raw materials costs in the past. Since we began using green pipes produced by our former subsidiary Jiangsu Fanli and our hot-rolling pipe plant in 2007, the costs of round steel billets have become the primary component of our costs of raw materials. The remaining components of our manufacturing costs include shipping and handling costs, labor, utility, depreciation and miscellaneous expenses such as overhead costs, maintenance costs and sundry costs. Labor costs consist of wages, salaries and other statutory employee benefits for our production workers. Depreciation includes charges on our machinery and equipment for the production of our goods. We include in our cost of revenues write-down for value of potentially obsolete or slow-moving inventories, based on specific analysis of our sales forecasts and inventory conditions.

We incur significant shipping and handling costs in connection with the shipping of our products to our customers located in other parts of China and overseas. We usually deliver our finished products to customers in China by train or by truck in circumstances requiring urgent delivery. Our overseas deliveries are primarily made by ship. Our export contracts are usually entered into on a Free On Board, or FOB, basis, which means that we pay for shipping of the goods to the port of shipment, plus loading costs. Our customers pay freight, insurance, unloading costs and shipping from the port of destination to the factory. We engage a number of overseas shipping agents to transport our finished products overseas. Shipping and handling costs were $33.8 million, $41.0 million and $32.5 million in 2010, 2011 and 2012, respectively.

VAT in China is charged on sales at a general rate of 17% based on the sales price of our products to customers. We are deemed to have paid a 4% VAT based on the general rate minus a 13% VAT refund on export sales, which we are entitled to receive immediately upon filing the VAT returns. The 4% VAT is recorded as a cost of revenues on export sales.

Operating expenses

Our operating expenses include selling and marketing expenses, impairment of long-lived assets and general and administrative expenses.

Selling and marketing expenses

Selling and marketing expenses primarily include salary and benefits, samples, promotion and marketing expenses, and commissions or service fees to sales agents.

We generally sell our products directly to oilfields in China through our four sales offices located in the Daqing, Changqing, Xinjiang and Sichuan oilfields, which cover all major oilfields in China. Internationally, we sell our products primarily through distributors and sales agents. We sell directly to our distributors, who interact independently with the end-customers. With respect to sales agents, we typically pay them a commission or a service fee.

Our selling and marketing expenses also include costs of product warranties. In connection with the warranties relating to our products, we provide a warranty to customers that our products will meet the stated functionality as agreed to in each sales contract. We provide for the estimated warranty costs under these guarantees based upon historical experience and management’s estimate of the level of future claims. Our provisions for estimated warranty costs were $0.5 million, $4.0 million and $5.5 million in 2010, 2011 and 2012, respectively. The increase in provisions for estimated warranty costs from 2010 to 2011 was primarily due to a provision made for a legal settlement in the United States. We have defective product issues occasionally and such defects typically become evident within the first few months of sales.

General and administrative expenses

General and administrative expenses comprise primarily of salaries and benefits, share-based compensation expenses, professional fees, guarantee fees, and business travel expenses.

We incurred general and administrative expenses of approximately $67.0 million, $61.8 million and $78.1 million in 2010, 2011 and 2012, respectively. Our general and administrative expenses decreased from 2010 to 2011 primarily due to the accrual by one of our subsidiaries of an impairment loss of approximately $17.1 million, and increased from 2011 to 2012 primarily due to the increased expenses generated from production stoppage of a number of our subsidiaries, such as depreciation of equipment and salary expenses reclassified to general and administrative expenses. In addition, the disposal of production facilities held by Houston increased our general and administrative expenses.

50

Impairment on long-lived assets

We measure impairment by comparing the carrying value of the long-lived assets to future undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, we would recognize an impairment loss based on the fair value of the assets.

Based on the results of our impairment test, we recorded an impairment charge of $17.1 million for Chaoyang Seamless in 2010, nil in 2011 and nil in 2012. We did not conduct an impairment test for Houston OCTG, as its production facilities were sold in November 2012.

Research and development expenses

Our research and development expenses are not disclosed as a separate item in the income statement but allocated to cost of revenues and other operating expenses, depending on whether the costs are related to the design, production, testing or enhancement of our products and manufacturing process and the personnel who participate in the research and development projects. The OCTG industry in which we operate is characterized by rapid development and increasing demand for non-API products. In 2006, we did not have a separate department for research and development, even though many employees have devoted part of their time in research and development activities. We established our research and development department in July 2007. We incurred research and development expenses of approximately $1.7 million, $1.5 million and $1.5 million in 2010, 2011 and 2012, respectively. We expect to incur more research and development expenses in the future as we devote greater resources to improving our technical know-how in OCTG production, in particular relating to the production of non-API products.

Other operating income (expense)

Other operating income (expense) primarily includes income or expense from sales of auxiliary materials and gains or losses from disposal of fixed assets. We do not expect that other operating income (expense) will be material in our business.

Taxation

WSP Holdings is a tax-exempted company incorporated in the Cayman Islands. FSHL is a tax-exempted company incorporated in the British Virgin Islands.

FSHL’s subsidiaries registered in China are subject to the New EIT Law on the taxable income in accordance with the relevant PRC income tax laws.

In September 2008, WSP China was officially granted the “high and new technology enterprise” status for a period of three years with retrospective effect from January 1, 2008. Therefore, WSP China is entitled to a preferential income tax rate of 15% in 2008, 2009 and 2010 as long as it maintains its qualification as a “high and new technology enterprise” under the New EIT Law. WSP China has used the 15% preferential tax rate in the calculation of current and deferred tax balances, which was consistent with the preferential tax rate applicable to WSP China prior to January 1, 2008. In September 2011, we obtained an approval from the PRC authorities for a renewal of the “high and new technology” enterprise status, effective retroactively from January 1, 2011. We expect that WSP China will maintain its qualification as a “high and new technology enterprise” in the foreseeable future as it has successfully fulfilled the required conditions in the past. See “—C. Research and Development” for more information relating to our research and development results and efforts. If WSP China fails to maintain the “high and new technology enterprise” status, the calculation of deferred tax balances will be based on the uniform tax rate of 25%.

As of December 31, 2010, 2011 and 2012, the measurement of our deferred tax assets has been reduced by a valuation allowance in the amount of $33.1 million, $47.3 million and $52.2 million, respectively, as based on the available evidence it is more likely than not that some portion of our deferred tax assets are not expected to be realized. The recognition of valuation allowance has partly contributed to the decrease in our effective income tax rate in 2010, 2011 and 2012.

Our other entities registered in China are subject to the 25% enterprise income tax rates. Houston OCTG is subject to United States federal corporate income tax rate of 34% and Texas state margin tax.

51

The subsidiaries of FSHL that are tax residents in China are subject to the PRC dividend withholding tax at 10% when these Chinese subsidiaries distribute dividends paid out of profits that arise on or after January 1, 2008. In 2009, following FSHL’s qualification as a tax resident company in the Hong Kong Special Administrative Region, a withholding tax at 5% will be applicable on China dividends paid to FSHL. The qualification for tax residency in the Hong Kong Special Administrative Region is subject to an annual application and renewal process. FSHL made no renewal in 2011 and 2012 due to the continued operating losses of its PRC subsidiaries. A provision for PRC dividend withholding tax of $0.8 million has been made based on the 40% of the 2009 undistributed earnings of our PRC subsidiaries as of December 31, 2009, which are expected to be distributed. The remaining undistributed earnings of our PRC subsidiaries of approximately $90.8 million at December 31, 2009 are considered to be reinvested, and no deferred tax liability has been made for the PRC dividend withholding taxes that would be payable upon the distribution of those amounts to FSHL as of December 31, 2009. In 2009, we distributed dividends out of the annual profits of WSP China for the year ended December 31, 2007. No withholding tax is necessary on any dividend amount paid out of retained earnings of WSP China before January 1, 2008. A reversal of provision for PRC dividend withholding tax of $0.4 million was made based on 40% of the 2010 undistributed earnings of the Company’s PRC subsidiaries due to operating losses. As of December 31, 2011 and 2012, no provision for PRC dividend withholding tax was required to be made for our PRC subsidiaries due to continued operating losses.

The calculation of income taxes reflects the status of WSP Holdings and FSHL as non-China tax resident companies. The tax residency of a company is normally a question of fact. For a company, such as WSP Holdings and FSHL, which has been established outside China, tax residency will only be in China if the location of effective management of the company is in China.

Because the concept of tax residency is new in China, it is possible that the tax authorities may in the future assert that WSP Holdings and/or one or more of its non-Chinese subsidiaries are tax residents in China. In the event that this occurs, WSP Holdings or FSHL will become subject to the New EIT Law on its worldwide income. This would cause any income earned by WSP Holdings and FSHL to be subject to China’s 25% EIT. As there is an exemption for any dividends received by a China tax resident company from another tax resident company, such taxable income would not include any dividends from the Chinese subsidiaries.

We have made an assessment of the level of tax authority based on the technical merits for each tax position, including the potential application of interest and penalties, and have measured the unrecognized tax benefits associated with the tax positions. As of December 31, 2010, 2011 and 2012, the Company had additional unrecognized tax benefits of $3,698, nil and nil, respectively, that related to net operating loss carryforwards. The aforementioned liability is recorded as non-current liabilities because the related payment is not anticipated within one year of the balance sheet date. In 2010, the Company had recorded an additional liability for an uncertain tax position related to the government grant received by one of its subsidiaries. We classify interest and/or penalties related to income tax matters in income tax expense. We had additional accrued interest and penalties as of December 31, 2010, 2011 and 2012 of approximately $2,558,000, $944,000 and $792,000, respectively, arising from the unrecognized tax benefit balances for 2007.

For a discussion on VAT, see “Item 5—A. Operating Results—Overview of financial results—Cost of revenues.”

Critical accounting policies

We prepare our financial statements in conformity with U.S. GAAP, which require us to make judgments, estimates and assumptions. We continually evaluate these estimates and assumptions based on the most recently available information, our own historical experience and various other assumptions that we believe to be reasonable under the circumstances. Since the use of estimates is an integral component of the financial reporting process, actual results could differ from those estimates.

An accounting policy is considered critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time such estimate is made, and if different accounting estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the consolidated financial statements. We believe that the following accounting policies involve a higher degree of judgment and complexity in their application and require us to make significant accounting estimates. The following descriptions of critical accounting policies, judgments and estimates should be read in conjunction with our consolidated financial statements and other disclosures included in this annual report.

52

Revenue recognition

We recognize revenue when persuasive evidence of an arrangement with the customer exists, the product has been shipped and title has passed, provided that we do not have significant future performance obligations, the amount due from the customer is fixed or determinable, and collectability is reasonably assured. There is no significant customer acceptance process. We assess whether the amount due from the customer is fixed or determinable based on the payment terms of the agreement. We assess collection based on a number of factors, including past transaction history with the customer and creditworthiness of the customer.

We present revenue net of value added tax, sales returns and applicable local government levies.

Iron ore sales

Sales of iron ore is recognized on the same criteria above except that revenue is recognized when the iron ore is collected by the customer at the destination port. We record the sales of iron ore on a gross basis, as we act as principal in the transaction taking the risks and rewards of ownership and take the title of the products.

In November 2009, we entered into a five-year commitment to purchase a minimum of 300,000 tonnes of iron ore pellets to be delivered by separate shipments on a yearly basis from 2010 through 2014. The commitment for purchase of iron ore pellets is not determinable as the contract does not include a stated purchase price.

In November 2010, we entered into another commitment to purchase approximately 600,000 tonnes of iron ore fines for a total amount of $75 million. The commitment for purchase of iron ore fines is to be completed within a period of one year through one or two shipments per month. However, this commitment expired in 2011 through lapse of time, as no shipments were made over the one-year period.

Warranty

We sell the majority of our products to customers along with unconditional repair or replacement warranties for a 12-month period from the date of purchase. We determine the estimated liability for warranty claims based on our historical experience and management’s estimate of the level of future claims. Our provision for warranty claims is derived based on the average percentage of actual warranty claims over our revenues in the past five years. Our estimate of the accrued product warranty claims may change in the near term depending on the significance of our sales to the United States and any unsettled warranty claims. We foresee fewer warranty claims in the future due to the significant decline in our sales to the United States. Estimated costs for product warranties are recognized at the time when revenue is recognized.

Impairment of long-lived assets

We review our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When these events occur, we measure impairment by comparing the carrying amount of the asset to future undiscounted net cash flows expected to result from the use of the asset and its eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the asset, we will recognize an impairment loss based on the fair value of the asset. In recent years, we have experienced a low capacity utilization of our production facilities due to unfavorable economic conditions. In view of these changes in our operating circumstances and the operating losses incurred by certain asset groups, we performed an impairment test for these asset groups namely, WSP China, Liaoyang Seamless, Songyuan Seamless, Mengfeng, Bazhou Seamless and WSP Pipe on December 31, 2012. The future undiscounted net cash flows of the asset groups exceed their carrying amounts and therefore we recognized no impairment loss. The impairment test that we performed for certain asset groups on December 31, 2012 was assisted by an independent third party valuation firm. The valuation analysis, which is based on our financial projections, utilizes generally accepted valuation methodologies such as the future undiscounted net cash flows as stipulated under the step one of the two-step process of the relevant authoritative accounting pronouncement. The valuation analysis considers certain principal factors such as the nature, financial and operating results of our business, the global economic outlook in general and the specific economic and competitive elements affecting our business, industry and market, the market-derived investment returns of entities engaged in a similar line of business and returns from other similar types of projects, the stage of development, contemporaneous business plans and relevant financial risks of our business. The valuation analysis also incorporates certain major assumptions concerning the political, legal, fiscal and economic conditions, future movement of exchange rates and interest rates, the availability of financial resources, management competency and availability of key personnel, industry trends and market conditions. Based on the result of the impairment test, the aggregate future undiscounted net cash flows from the reporting units is greater than the sum of carrying value of the relevant reporting units by approximately $1.3 billion.

53

The projected undiscounted cash flow estimate included, among other things, an analysis of projected revenue growth, gross margins, effective tax rates, capital expenditures and working capital requirements. These assumptions are inherently uncertain and subjective. The key assumptions of our cash flow forecasts were consistent with the assumptions that we used in developing our business plan, which included:

·Net revenues of WSP China will grow at a compound annual growth rate, or CAGR, of -0.4% for the periods between 2012 and 2019, with sales volume of up to 460,000 tonnes of finished products. As Bazhou Seamless is projected to operate under normal capacity, net revenues will grow at CAGR of 51.8%. Sales price of finished products per tonne is expected to increase by 2.6% to 3.9% per annum.

·Cost of revenues is projected to increase by 0.6% to 2.7% for all asset groups from 2012 through 2019, except for Songyuan Seamless and Mengfeng, where cost of revenues is projected to decrease by 5.6% and 0.5%. Cost of revenues for all assets group represents approximately 77.1% to 95% of sales.

·Operating expenses as a percentage of net revenues are expected to remain at 2.0% to 9.3% for all asset groups during the projection period.

·The availability of finance will not be a constraint on the forecasted growth of all asset groups’ related business.

·There will be no material changes in the existing political, legal, fiscal and economic conditions in China;

·There will be no material deviation in industry trends and market conditions from economic forecasts.

Goodwill

The excess of the purchase price over the fair value of net assets acquired is recorded on the consolidated balance sheet as goodwill. Goodwill is not amortized but is tested for impairment annually or more frequently if events or changes in circumstances indicate that it might be impaired. We perform an annual goodwill impairment test on December 31 of each fiscal year for all reporting units. Goodwill is tested following a two-step process. The first step compares the fair value of each reporting unit to its carrying amount, including goodwill. If the fair value of each reporting unit exceeds its carrying amount, goodwill is not considered to be impaired and the second step will not be required. If the carrying amount of a reporting unit exceeds its fair value, the second step compares the implied fair value of goodwill to the carrying value of a reporting unit’s goodwill. The implied fair value of goodwill is determined in a manner similar to accounting for a business combination with the allocation of the assessed fair value determined in the first step to the assets and liabilities of the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned to the assets and liabilities is the implied fair value of goodwill. An impairment loss is recognized for any excess in the carrying value of goodwill over the implied fair value of goodwill. The Company’s goodwill resulted from the acquisition of Chaoyang Seamless in 2009. There was no impairment loss identified on goodwill for the year ended December 31, 2011. After the disposal of Chaoyang Seamless in January 2012, the Company no longer holds any goodwill.

Accounts receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Amounts collected on trade accounts receivable are included in net cash provided by operating activities in the consolidated statements of cash flows.

The allowance for doubtful accounts is our estimate of the amount of probable credit losses in our existing accounts receivable. We consider factors such as customer credit-worthiness, past transaction history with the customer and current economic industry trends when we determine the collectability of specific customer accounts. Allowance for doubtful accounts for accounts receivable was $20.1 million, $22.6 million and $22.8 million as of December 31, 2010, 2011 and 2012, respectively. The slight increase in allowance for doubtful accounts from 2010 to 2011 was primarily due to an increase in provisions for long overdue receivables.

54

Inventories

Inventories are stated at the lower of cost or market. Cost is determined by the weighted average method. Cost comprises direct materials and where applicable, direct labor costs, toll manufacturing costs and overhead that has been incurred in bringing the inventories to their present location and condition. Write-downs of potentially obsolete or slow-moving inventories are recorded based on the management’s specific analysis of future sales forecasts and economic conditions.

Income taxes

Deferred income taxes are recognized for temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements, net operating loss carry forwards and credits, by applying enacted statutory tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws and regulations applicable to us as enacted by the relevant tax authorities.

Management must exercise significant judgment to determine our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. We base the valuation allowance on our estimates of taxable income in each jurisdiction in which we operate and the period over which our deferred tax assets will be recoverable. If actual results differ from these estimates or we adjust these estimates in future periods, we may need to establish an additional valuation allowance, which could materially impact our financial position and results of operations.

U.S. GAAP requires that an entity recognize the impact of an uncertain income tax position on the income tax return at the largest amount that is more likely than not to be sustained upon audit by the relevant tax authority.

Contingencies

Certain conditions may exist as of the date the financial statements are issued, which may result in a loss to us which will only be resolved when one or more future events occur or fail to occur. We assess such contingent liabilities, and such assessment inherently involves an exercise of judgment. If the assessment of a contingency indicates that it is probable that a material loss has been incurred and the amount of the liability can be estimated, then the estimated liability would be accrued in our financial statements. If the assessment indicates that a potentially material loss contingency is not probable but is reasonably possible or is probable but cannot be estimated, then the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, would be disclosed.

Internal control over distribution of our products

In the years ended December 31, 2010, 2011 and 2012, we did not have any direct sales to Sanctions Targets.

We sell our products in international markets primarily through independent, non-U.S. distributors who are responsible for interacting with the end customers of our products. We have limited control over the parties to whom these independent distributors resell our products, and certain independent distributors may have sold an insignificant amount of our products to Sanctions Targets. We are aware of an insignificant amount of resales of our products by two non-U.S. and non-affiliated distributor customers to Sudan, a Sanctions Target, during the three years ended December 31, 2012. To the best of our knowledge, in 2010, 2011 and 2012, our indirect sales to Sanctions Targets accounted for approximately 1.1%, 0.6% and nil, respectively, of our net revenues.

We have adopted a written policy to prevent direct or indirect sales to Sanctions Targets and have begun to implement internal control mechanisms to enforce such policy, which include contractually requiring all of our distributors to covenant with us that they will not resell any of our products to any Sanctions Targets. However, we cannot guarantee that our measures will be able to prevent future sales or resales of our products to Sanctions Targets. See “Item 3. Key Information—D. Risk factors—Risks related to our business—We may be unable to prevent possible resales or transfers of our products to countries, governments, entities, or persons targeted by United States economic sanctions, especially when we sell our products to distributors over which we have limited control.”

Year ended December 31, 2012 compared to year ended December 31, 2011

Net revenues

Our net revenues decreased by 18.2% from $686.1 million in 2011 to $561.3 million in 2012.

·API products. Sales of our API products decreased by 10.2% from $446.2 million in 2011 to $400.6 million in 2012 primarily due to decreases in sales volume. Sales volume of our API products decreased by 8.6% from 391,088 tonnes in 2011 to 357,530 tonnes in 2012, primarily due to decreased demand for our API products in the domestic market. The average sales price of our API products decreased from $1,141 per tonne in 2011 to $1,121 per tone in 2012, primarily due to the decrease in export price of API products.

·Non-API products. Sales of our non-API products decreased by 37.7% from $144.8 million in 2011 to $90.2 million in 2012 primarily due to decreases in sales volume of non-API products in 2012. Sales volume of our non-API products decreased by 24.9% from 72,358 tonnes in 2011 to 54,369 tonnes in 2012, primarily due to decreased demand for our non-API products in the international markets. The average sales price of our non-API products decreased from $2,001 per tonne in 2011 to $1,658 per tone in 2012, primarily due to sales of lower priced non-API products in the domestic market.

·Iron ore. Sales of iron ore were nil for both 2011 and 2012 due to our internal lack of iron ore pellet requirements and low market demand for sales of iron ore pellets. However, in 2012, we received commissions of approximately $2.7 million from our supplier for finding a third-party buyer for 334,117 tonnes of iron ore pellets.

·Other products. Sales of other products decreased by 25.9% from $95.1 million in 2011 to $70.5 million in 2012, primarily due to the decrease in sales volume of other products.

56

Net revenues from domestic sales decreased by 14.5% from $364.9 million in 2011 to $312.1 million in 2012, primarily due to lower sales volume as a result of decreased demand for our products.

Net revenues from export sales decreased by 22.4% from $321.2 million in 2011 to $249.2 million in 2012, primarily due to lower sales volume as a result of the weakening demand for our non-API products in the international markets.

Cost of revenues

Our cost of revenues decreased by 15.8% from $637.6 million in 2011 to $536.8 million in 2012, primarily due to the decreases in raw material purchases, utility costs and labor due to lower production activities and scale of operations. Shipping and handling costs decreased by 20.6% from $41.0 million in 2011 to $32.5 million in 2012. Our cost of revenues as a percentage of net revenues increased from 92.9% in 2011 to 95.6% in 2012. The increase was primarily attributable to the decrease in production line utilization leading to increasing costs of processing products.

Gross profit and gross margin

As a result of the foregoing, our gross profit decreased by 49.5% from $48.5 million in 2011 to $24.5 million in 2012. Our gross margin decreased from 7.1% in 2011 to 4.4% in 2012, primarily due to the decrease in production line utilization leading to increasing costs of processing products, as well as slight decreases in selling prices.

Selling and marketing expenses

Our selling and marketing expenses decreased by 50.1% from $34.5 million in 2011 to $17.2 million in 2012, primarily due to decreasing sales volume of our products which resulted in lower selling and marketing activities. Our selling and marketing expenses as a percentage of net revenues decreased from 5.0% in 2011 to 3.1% in 2012.

General and administrative expenses

Our general and administrative expenses increased by 26.5% from $61.8 million in 2011 to $78.1 million in 2012, primarily due to the increased expenses generated from production stoppage of a number of our subsidiaries, such as depreciation of equipment and salary expenses reclassified to general and administrative expenses. In addition, the disposal of production facilities held by Houston OCTG increased our general and administrative expenses. Our general and administrative expenses as a percentage of net revenues increased from 9.0% in 2011 to 13.9% in 2012.

Interest expenses, net

Our net interest expense increased by 19.6% from $30.6 million in 2011 to $36.6 million in 2012, primarily due to the decrease of interest capitalization.

Income tax expenses

We had an income tax expense of $0.1 million in 2011, compared to an income tax benefit of $6.1 million in 2012, primarily due to our subsidiaries’ loss from operations, which resulted in increased income tax benefits. Our effective tax rate was 5% in 2012, compared to nil in 2011, primarily due to the increase in income tax benefits.

Net loss

As a result of the foregoing, we had net loss of $89.9 million in 2012, compared to net loss of $76.8 million in 2011. Our net margin was negative 16.0% in 2012, compared to negative 11.2% in 2011.

Net loss attributable to WSP Holdings Limited

As a result of the foregoing, net loss attributable to WSP Holdings Limited was $84.2 million in 2012, compared to $68.5 million in 2011. Net margin attributable to us was negative 15.0% in 2012, compared to negative 10.0% in 2011.

Year ended December 31, 2011 compared to year ended December 31, 2010

Net revenues

Our net revenues increased by 45.8% from $470.5 million in 2010 to $686.1 million in 2011.

57

·API products. Sales of our API products increased by 60.9% from $277.3 million in 2010 to $446.2 million in 2011 primarily due to increases in sales volume and average sales price. Sales volume of our API products increased by 43.8% from 271,986 tonnes in 2010 to 391,088 tonnes in 2011, primarily due to increased demand for our products in both the domestic and international markets as a result of contract wins in South America and increased orders from our primary PRC customers under improved market conditions. The average sales price of our API products increased from $1,020 per tonne in 2010 to $1,141 per tonne in 2011, primarily due to sales of higher-priced API products in both the domestic and international markets.

·Non-API products. Sales of our non-API products increased by 106.4% from $70.1 million in 2010 to $144.8 million in 2011 primarily due to increases in sales volume and average sales price. Sales volume of our non-API products increased by 92.7% from 37,543 tonnes in 2010 to 72,358 tonnes in 2011, primarily due to increased demand for our products in both the domestic and international markets as a result of increased orders from our primary PRC customers under improved market conditions. The average sales price of our non-API products increased from $1,868 per tonne in 2010 to $2,001 per tonne in 2011 primarily, due to sales of higher-priced non-API products in the international markets.

·Iron ore. Sales of iron ore was nil in 2011 compared to $31.9 million in 2010 due to our internal lack of iron ore pellet requirements and low market demand for sales of iron ore pellets.

·Other products. Sales of other products increased by 4.4% from $91.1 million in 2010 to $95.1 million in 2011 due to an increase in sales of unfinished products to meet our customers’ production requirements.

Net revenues from domestic sales increased by 23.7% from $294.9 million in 2010 to $364.9 million in 2011 primarily due to increases in average sales price and total sales volume of our products as a result of increased orders from our primary PRC customers under improved market conditions.

Net revenues from export sales increased by 83.0% from $175.5 million in 2010 to $321.2 million in 2011 primarily due to higher sales volume as a result of improving demand for our products in the international markets, including contract wins in South America, and an increase in the average sales price. Our products in the international market command a price premium and our export prices are usually set based on the prevailing market prices, which are generally higher than the domestic prices.

Cost of revenues

Our cost of revenues increased by 36.4% from $467.4 million in 2010 to $637.6 million in 2011 primarily due to increases in raw materials purchases, utility costs and employee costs as a result of higher production activities and scale of operations. Shipping and handling costs increased by 21.2% from $33.8 million in 2010 to $41.0 million in 2011. Our cost of revenues as a percentage of net revenues decreased from 99.3% in 2010 to 92.9% in 2011. The decrease was primarily attributable to an increase in our average sales prices of our API and non-API products.

Gross profit and gross margin

As a result of the foregoing, our gross profit increased by 1,482.7% from $3.1 million in 2010 to $48.5 million in 2011. Our gross margin increased from 0.7% in 2010 to 7.1% in 2011, primarily due to higher sales prices of our API and non-API products.

Selling and marketing expenses

Our selling and marketing expenses increased by 65.5% from $20.8 million in 2010 to $34.5 million in 2011, primarily due to increases in sales commissions attributable to higher export sales and provisions for product warranty claims. As a result, our selling and marketing expenses as a percentage of net revenues increased from 4.4% in 2010 to 5.0% in 2011.

General and administrative expenses

Our general and administrative expenses decreased by 7.8% from $67.0 million in 2010 to $61.8 million in 2011, primarily due to decreased legal settlement charges from 2010 to 2011 relating to a legal settlement charge of approximately $7.8 million with a customer in 2010. Our general and administrative expenses as a percentage of net revenues decreased from 14.2% in 2010 to 9.0% in 2011.

58

Interest expenses, net

Our net interest expense increased by 17.5% from $26.0 million in 2010 to $30.6 million in 2011, primarily due to an increase in borrowings resulted from increased working capital requirements.

Income tax expenses

Our income tax expenses decreased from $9.4 million in 2010 to $0.1 million in 2011, primarily due to a lower tax expense and an increase in deferred tax credits attributable to losses from operations. Our effective tax rate was 0% in 2011, compared to negative 8.0% in 2010, primarily due to decreases in provision of valuation allowance on deferred income tax assets, expenses eligible for tax deductions and unrecognized tax benefits.

Net loss

As a result of the foregoing, we had net loss of $76.8 million in 2011, compared to our net loss of $132.8 million in 2010. Our net margin was negative 11.2% in 2011, compared to negative 28.2% in 2010.

Net loss income attributable to WSP Holdings Limited

As a result of the foregoing, net loss attributable to us was $68.5 million for the year ended December 31, 2011, compared to net loss attributable to us of $118.8 million for the year ended December 31, 2010. Net margin attributable to us was negative 10.0% in 2011, compared to negative 25.2% in 2010.

B.     Liquidity and Capital Resources

Cash flows and working capital

Since 2009, we have experienced a significant decline in sales to the United States due to anti-dumping and countervailing duties on seamless pipes made in China imposed by the United States government. See “Item 8—Financial Information—A. Consolidated Statements and Other Financial Information—Legal proceedings.” Products sold to the United States accounted for 9.7%, 6.3% and 9.3% of our net revenues in 2010, 2011 and 2012, respectively, compared to 34.3% of our net revenues in 2008, the year before the enactment of the anti-dumping and countervailing duties. As a result, our business operations have been adversely affected, and we suffered significant operating losses and working capital deficiencies in 2010 and 2011.  As of December 31, 2012, we had cash and cash equivalents balance of $26.1 million, restricted cash of $206.8 million, term deposits of $0.3 million, unused bank credit facilities of $36.1 million and short-term borrowings of $787.0 million.

Future uses of cash will include, among others:

·Continuing capital expenditures;

·Repayment of bank borrowings; and

·Continuing use of cash in operations.

We have taken various actions to conserve cash, procure additional financing and improve the liquidity. Such actions include reducing working capital requirements in operations through reduction of accounts receivables, inventories and other measures and reducing capital spending through delaying or scaling down certain projects. Our ability in meeting future cash flow requirements is dependent on many events outside of our direct control, including, among other things, successful renewal of bank borrowings, additional financing from the banks and capital market, and recovery of demand and selling prices for OCTG products.

In August 2011, one of our subsidiaries entered into a syndicated bank credit facility agreement with two major lead commercial banks and six other participating commercial banks, which provide us with a syndicated bank credit facility of up to RMB3.5 billion (with an initial commitment of RMB2.86 billion) for a term up to three years from the first drawdown date. The interest will accrue on a daily basis at a rate equal to five percent plus the prevailing interest rate published by the People’s Bank of China on the unpaid principal balance then outstanding.

59

According to the repayment schedules specified in the loan agreements, which do not include $210.9 million of borrowings due after one year that was reclassified as current liability due to breach of financial covenants, $501.7 million of the borrowings became due for repayment during the first nine months of 2013. We were able to renew $70.2 million and repay $431.4 million of these borrowings and obtained new bank borrowings of $470.9 million. While we are required to repay approximately $256.9 million bank borrowings for the remainder of 2013, we believe we will be able to renew a substantial portion of our bank borrowings and bank credit facilities as they fall due. For details on our borrowings, please see “—Borrowings.”

In order to counteract the adverse impact of anti-dumping and countervailing duties imposed by the United States, we have actively pursued new opportunities in other international markets. Since the end of 2010, we secured several new order wins in the international markets such as Venezuela and Ecuador. In 2012, we secured new contract wins for sales of our products to Oman. In the first three quarters of 2013, we secured new contract wins for sales of our products to United Arab Emirates.

In the past, we had significant working capital commitments for purchases of raw materials, which included commitments for purchases of iron ore pellets from an iron ore supplier. However, we foresee no significant or immediate working capital commitments for purchases of iron ore pellets due to the fact that the contractual terms have not been strictly performed by the supplier and us in practice and that certain contractual terms are still subject to further negotiations between we and the supplier. Additionally, we made no purchases from this supplier in 2011 due to our internal lack of iron ore pellet requirements and low market demand for sales of iron ore pellets. We expect to maintain a similar level of working capital requirements in 2013 as 2012. We expect that we will be able to meet our working capital requirements in 2013 with cash flows generated from our operations and our credit facilities. For details on our borrowings, please see “—Borrowings.”

The following table sets forth a summary of our cash flows for the periods indicated.

Operating activities

Net cash generated from operating activities was $3.3 million in 2012, compared to net cash generated from operating activities of $60.8 million in 2011. Net cash generated from operating activities in 2012 was primarily attributable to net loss of $89.9 million adjusted by depreciation of property, plant and equipment of $48.4 million, a decrease in accounts payable in the amount of $6.8 million resulting from our decreasing use of bills payable, a decrease in other payables and accrued expenses in the amount of $12.2 million due to slower operating activities, and a decrease in advances from customers in the amount of $3.4 million, partially offset by a decrease in accounts receivable in the amount of $54.6 million resulting from decreased product sales and a decrease in inventories of $37.9 million.

Net cash generated from operating activities was $60.8 million in 2011, compared to net cash used in operating activities of $5.1 million in 2010.

Investing activities

Net cash generated from investing activities was $47.3 million in 2012, compared to net cash used in investing activities of $187.6 million in 2011. Net cash generated from investing activities in 2012 was primarily attributable to a decrease in restricted cash of $47.7 million due to a decrease in our use of bank acceptance bills which required cash deposits as security and the disposal of Houston OCTG’s assets and fixed assets of approximately $38.6 million.

Financing activities

Net cash used in financing activities was $45.3 million in 2012, compared to net cash provided by financing activities of $97.6 million in 2011.

Borrowings

We had the following outstanding borrowings as of the dates indicated.

	As of December 31,
(in thousands)	2010		2011		2012
Short-term bank loans	$	508,355	$	714,310	$	743,833
Credit from bills receivable discounted with recourse	88,191		38,916		43,154
Long-term bank loans due for settlement over one year	135,896		79,354		15,910
Long-term bank loan due for settlement within one year	—		20,315		—
Total	$	732,442	$	852,895	$	802,897

Our bank and other borrowings increased in 2010 and 2011 mainly due to the expansion of our production capacity and our working capital requirements. In 2012, our bank and other borrowings decreased mainly due to a decrease in expenditures and the disposal of assets.

61

Our short-term borrowings are used primarily for working capital and capital expenditures purposes. As of December 31, 2010, 2011 and 2012, the average interest rate of our short-term bank loans was 6.0%, 6.2% and 6.5%, respectively. Our short-term bank loans have floating interest rates tied to the benchmark interest rate for loans of similar maturity announced by the People’s Bank of China. As of December 31, 2012, we had outstanding secured loans with an aggregate amount of $730.0 million, which were secured by certain land use rights, buildings, machines and equipment and letters of credit issued by other banks. Our short-term borrowings also include loans not due within one year that were reclassified as short-term borrowings due to technical breaches of these loans.

In August 2011, we entered into a syndicated bank credit facility agreement with two major lead commercial banks and six other participating commercial banks, which provide us with a syndicated bank credit facility of up to RMB3.5 billion (with an initial commitment of RMB2.86 billion) for a term up to three years from the first drawdown date. The interest will accrue on a daily basis at a rate equal to five percent plus the prevailing interest rate published by the People’s Bank of China on the unpaid principal balance then outstanding. This agreement contains financial covenants, which are applicable to one of our major operating subsidiaries, including maintenance of levels of debt to assets ratio not exceeding 72% in 2011, 71% in 2012 and 67% in 2013, minimum sales of RMB4 billion in 2011, RMB4.5 billion ($722.3 million) in 2012 and RMB5.5 billion ($882.8 million) in 2013, minimum net profit of RMB80 million in 2011, RMB150 million ($24.1 million) in 2012 and RMB350 million ($56.2 million) in 2013, minimum current ratio of 170% in 2011, 180% in 2012 and 180% in 2013, and minimum quick ratio of 120% in 2011, 130% in 2012 and 130% in 2013. As of December 31, 2012, we have drawn down approximately RMB2.7 billion ($424.4 million) out of the total approved loan facility of RMB2.9 billion ($455.0 million). Additionally, under these covenants, we must also meet certain ratios and thresholds at the end of a one-year special observation period from July 1, 2011 to June 30, 2012. These ratios and thresholds include maximum debt to asset ratio of 70%, minimum sales of RMB4.2 billion ($674.1 million), minimum net income of RMB100 million ($16.1 million), minimum current ratio of 170% and minimum quick ratio of 120%. As of December 31, 2012, our unutilized credit facilities amounted to $36.1 million. According to the repayment schedules specified in the loan agreements, which do not include $210.9 million of borrowings due after one year that was reclassified as current liability due to breach of financial covenants, $501.7 million of the borrowings became due for repayment during the first nine months of 2013. We were able to renew $70.2 million and repay $431.4 million of those borrowings and obtained new bank borrowings of $470.9 million. We are required to repay approximately $256.9 million in bank borrowings during the fourth quarter of 2013.

As of December 31, 2012, we had outstanding balance of long-term loans from two local banks of $15.9 million. These loans were obtained pursuant to various loan agreements that we entered into with the two local banks from 2009 to 2012. The loan agreements have terms ranging from one to six years. We used the loans primarily for project financing purposes. The interest rate will be adjusted periodically in accordance with the benchmark interest rate announced by the People’s Bank of China. In 2012, the average interest rate of our long-term loans was 6.8% and all long-term loans were secured loans.

Our facility agreements with certain commercial banks contain various covenants and conditions that limit our ability to conduct our business and restrict us from engaging in certain business activities. Some of these facility agreements include financial covenants, such as debt to assets ratio. Failure to maintain any of the financial covenants or a breach of any other restrictive covenants would result in a default under the relevant facility agreements and entitle the lenders to declare all borrowings outstanding, together with accrued and unpaid interests and fees, to be due and payable. In addition, our failure to comply with the financial or other covenants under the facility agreements could lead us to seek a waiver or an amendment of the covenants contained in the facility agreements, or alternative financing. Any waiver of the covenants in or amendment of the terms of our facility agreements may involve upfront fees, higher annual interest costs and other terms less favorable to us than those currently offered by the existing facilities. Additionally, we may not be able to obtain alternative financing on commercially reasonable terms or terms accepted to us, if at all.

Under the syndicated loan facility agreement for the year ended December 31, 2011, the special observation period was from July 1, 2011 to June 30, 2012 and the year ended December 31, 2012. In December 2012, the bank syndicate waived the past breaches of financial covenants during the observation period and agreed to continue to fulfill the terms of the syndicated loan facility. Additionally, we have informed the bank syndicate that we did not meet certain financial covenants for the year ended December 31, 2012. The bank syndicate held a review meeting and reached an agreement to waive the aforementioned breaches of financial covenants. The formal approval process within the bank syndicate is currently underway. However, the bank syndicate may not grant us a waiver for any future breaches or noncompliance.

Furthermore, based on the financial position and results of operations of one of our subsidiaries as of and for the year ended December 2009, such subsidiary failed to meet the financial covenant related to maximum debt to asset ratio under facility agreements with two banks. We agreed to implement measures to address these breaches and obtained waivers for these breaches from the two banks. Nonetheless, there was a delay in implementing certain remedial measures required by one bank and we remained non-compliant with relevant financial covenant in 2010, which gave the bank the right to accelerate repayment of the outstanding amount under the relevant facility agreement. The breach of covenant was rectified in April 2011. Notwithstanding the waiver, it was uncertain whether we would be able to meet the covenants in the future, and consequently the corresponding loans were reclassified as current liability. Accordingly, in 2012 we reclassified our long-term loans of $85.4 million from such bank into short-term loans due within one year. Additionally, another of our subsidiaries, which commenced commercial production in the second half of 2011, is also in breach of its financial covenants under a project loan. Accordingly, we reclassified our long-term loans of $31.5 million from such bank into short-term loans due within one year.

See “Item 3. Key Information—D. Risk Factors—Risks related to our business—Restrictive covenants under our facility agreements and any future indebtedness may limit the manner in which we operate and an event of default under any of our facility agreements and any future indebtedness may adversely affect our operations; and our financial leverage may hinder our ability to expand and materially affect our results of operations.” and “Item 3. Key Information—D. Risk Factors—Risks related to our business—We and our subsidiaries have been in breach of certain financial covenants under certain loan agreements, which, if not managed carefully, may trigger events of default and accelerated payment and adversely affect our business, financial condition and results of operations.”

We are in compliance with the financial covenants under our other facility agreements as of December 31, 2012.

Additionally, in 2012 and 2013 we also obtained high interest loans from non-commercial lenders. These loans typically had durations of no longer than seven days and annualized interest rates of approximately 90%. We paid interest of approximately RMB4.4 million ($0.7 million) and RMB2.7 million ($0.4 million) on these high interest loans in the year ended December 31, 2012 and the nine months ended September 30, 2013.

Bill financing

In the years ended December 31, 2010, 2011 and 2012 and to date in 2013, certain of our subsidiaries have used a portion of our credit facilities from certain banks as bill financing to fund a portion of our working capital requirements and business operational needs.  These transactions may not be in compliance and in certain cases were not with relevant PRC laws and regulations.

Under their terms, the bill financing facilities should be used to finance trade purchases. However, we entered into certain bill financing arrangements where the amounts of bank and commercial acceptance notes drawn down on the banks under the facilities were greater than our real expectation of purchasing needs from suppliers, which included both our subsidiaries and third parties. Moreover, on some occasions, the same purchase contracts (required for the issuance of bank acceptance notes under the bill financing facilities) were presented to two or more different banks to obtain financing. A portion of the notes we issued to our subsidiaries and third-party suppliers were then presented by the relevant suppliers to the banks for collection of an amount equal to the face value of the notes after deducting interest. Cash received from the notes presented in excess of the actual amount of purchases was then provided to us and utilized for operational purposes.

These bill financing arrangements were not in compliance with the general principles under the PRC Negotiable Instruments Law. However, we continued to enter into other such arrangements in 2013. The cash thereby obtained was then refunded by the suppliers to us. The total amount of the bill financing, being the difference between the aggregate amount of such bank and commercial acceptance notes issued and the aggregate amount of related actual purchases, was approximately RMB323.6 million, RMB1.419 billion, RMB757.8 million ($120.6 million) and RMB1,191.0 million ($193.7 million) in 2010, 2011 and 2012 and the nine months ended September 2013, respectively. Excluding the cash deposits that we paid upfront to the endorsing banks pursuant to the arrangements, the funding we obtained from the banks through this kind of bill financing in 2010, 2011 and 2012 and the nine months ended September 30, 2013, was estimated to be approximately RMB354.8 million, RMB323.6 million, RMB213.2 million ($33.9 million) and RMB693.8 million ($112.9 million), respectively.

We have sought legal advice from our PRC legal advisor regarding these bill financing arrangements. Considering the relevant factors including, in particular, that we have settled in the past these notes when they were due, and under the assumption that we are able to settle the outstanding notes when they become due, our PRC legal advisor subsequently issued a legal opinion stating that our bill financing arrangements in the years ended December 31, 2010, 2011 and 2012 would not result in any criminal or administrative liabilities on us or our senior management or directors, and there would not be any civil liabilities. The nature of our bill financing arrangements in the year ended December 31, 2012 has remained consistent with previous years. We have also obtained written confirmations from all of the endorsing banks that they will not take any legal action against us in connection with the bank and commercial acceptance notes that have been duly settled. We have settled all of the bank and commercial acceptance notes involved in the bill financing transactions in 2010, 2011 and 2012 that have become due. We expect to settle the notes from bill financing transactions that are outstanding on the date of this annual report when they become due.  Although we have obtained the written confirmations from all of the endorsing banks that they will not take any legal action against us in connection with the bank and commercial acceptance notes that have been duly settled, the endorsing banks may legal action regarding notes that we have settled regardless due to unforeseen reasons and circumstances beyond our control.

63

In 2012, additionally, for purposes of raising financing from a number of commercial banks, WSP China, Liaoyang Seamless and Songyuan Seamless entered into a number of intragroup transactions, under which WSP China sold approximately RMB251 million ($40.1 million) worth of goods to Liaoyang Seamless, Liaoyang Seamless sold approximately RMB252 million ($40.3 million) of goods to Songyuan Seamless and Songyuan Seamless sold approximately RMB252 million ($40.3 million) of goods to WSP China. Official sales invoices were issued for these transactions.  However, physical delivery of the underlying goods in these transactions did not occur.  As these transactions were intragroup, they did not have an overall impact on our consolidated revenues and did not result in additional tax payable, although the PRC GAAP reports of each of these three respective individual entities would have reflected sales not supported by physical delivery of the underlying goods. These sales invoices allowed our subsidiaries to obtain additional bill financing from a number of commercial banks.  Due to the nature of these transactions, these commercial banks may declare any of our borrowings to become immediately due and payable and terminate our credit facilities so that no additional borrowings can be obtained.  If any of these borrowings become immediately due and payable, we may not have the means to repay them.

Our management has conducted an assessment, including obtaining PRC legal advice and testing the design and the effectiveness of our internal control over financial reporting as of December 31, 2012. This assessment identified a material weakness that these transactions occurred without proper approval and may not be in compliance and in certain cases were not compliant with relevant PRC laws and regulations, and therefore our internal controls have not been operating effectively. See “Item 15. Controls and Procedures—Management’s annual report on internal control over financial reporting.”  In light of the current financial environment and our capital needs, we may continue to rely on such bill financing arrangements and continue to allow these borrowings relating to increased bills payable to remain until they are repaid upon maturity. Any actions by banks or regulators against us relating to these transactions could cause a disruption to our business operations and impact future financing arrangements with banks, which may have an adverse effect on our business conditions and cash flows.  The banks may take legal action against us if we fail to settle outstanding bank and commercial acceptance notes when they become due, which may disrupt our business and impact our long-term relationships with the banks and future financing plans.

Capital expenditures

Our capital expenditures are generally used to purchase buildings, plants and machinery. In 2010, 2011 and 2012, our capital expenditures amounted to $161.0 million, $93.4 million and $39.0 million, respectively.

Our major capital expenditure projects are almost completed and we have taken steps to slow down and eliminate certain expansion plans in view of our current capital conditions. We are in the process of completing the construction of a pipe heat treatment line with an annual processing capacity of 20,000 tonnes in Thailand through our subsidiary, WSP Pipe Ltd. The construction of our pipe heat treatment line with an annual processing capacity of 100,000 tonnes in Liaoyang through our subsidiary, Liaoyang Seamless, is also nearing completion. We estimate that our capital expenditures in 2013 will be approximately $27.0 million mainly attributable to balance of payments due to major capital expenditure projects which commenced in prior years. We have constantly been reevaluating and revising our capital expenditure plan based on the prevailing economic conditions and future expectations, as well as the availability of funding. We will monitor our expansion plans carefully to meet anticipated demand while taking appropriate cost cutting measures to ensure our financial stability.

We will continue to make capital expenditures from time to time to meet the expected growth of our operations. We expect that we will be able to meet our capital expenditures requirements in 2013 with cash flows generated from our operations and a similar level of bank borrowings as in 2012. As of December 31, 2012, our existing bank borrowings amounted to $802.3 million. We are monitoring the funding requirement for our capital expenditures and will make necessary adjustments to the capital investments related to our existing projects.

C.     Research and Development

We believe our strong commitment to research and development has been one of the key factors in our success. The OCTG industry in which we operate is characterized by rapid development and increasing demand for high quality products. We have focused our research and development efforts on the following major areas:

64

·development and application of new materials;

·design of premium connectors;

·improvement of production techniques (including improved corrosion-resistance and upsetting); and

·development of quality control systems.

Our senior management team leads our research and development efforts and sets strategic directions for the advancement of our products and manufacturing processes. We have a technical team to design and engineer our proprietary products and processes, many of whom have years of experience in the OCTG and steel industry. In addition, engineers from different departments also assist with our research and technology development activities on a project by project basis. The in-depth knowledge and expertise in the OCTG industry of our researchers and engineers enable us to conduct research and development of our products efficiently.

In 2006 we entered into a technological cooperation arrangement with Southwest Petroleum University in China to conduct collaborative research on drilling pipes. We have established a postdoctoral research program at our company, which is devoted to research in OCTG areas such as the development of oil well pipes and casing. We have also used our research capabilities to attract new recruits.

We plan to continue to invest in research and development in order to broaden our product offerings, especially with respect to our non-API products. Since 2006, our research and development team has focused on the development of new materials such as 13Cr, 9Cr, super high-intensity tubing and casing as well as hot-rolling processes. As of the date of this annual report, we had 132 patents and 67 pending patent applications in China and had developed several other proprietary processes and technologies as a result of our research and development activities, many of which we have applied in our manufacturing processes and our products. See “Item 4. Information on the Company—B. Business Overview—Intellectual property rights” for more information relating to our patents and patent applications.

D.     Trend Information

Other than as disclosed elsewhere in this annual report, we are not aware of any trends, uncertainties, demands, commitments or events for the period from January 1, 2012 to December 31, 2012 that are reasonably likely to have a material adverse effect on our net revenues, income, profitability, liquidity or capital resources, or that caused the disclosed financial information to be not necessarily indicative of future operating results or financial conditions.

E.     Off-Balance Sheet Commitments and Arrangements

As of December 31, 2012, we have provided guarantees to banks in respect of banking facilities utilized by Chaoyang Seamless. These guarantees were terminated in May 2013. We have also historically provided guarantees to banks in respect of banking facilities utilized by third parties. We recognize the liability for the guarantees at their fair value on the date of entering into the guarantee. These third parties also provided guarantees to us for some of our bank borrowings. Guaranteed parties included our related parties, vendors, processors and other unrelated parties, who had no trading relationship with us. There were no guaranteed balances of outstanding debt arrangements from third parties as of December 31, 2010, 2011 and 2012.

We have not entered into any derivative contracts that are indexed to our shares and classified as shareholder’s equity, or that are not reflected in our consolidated financial statements. Furthermore, we do not have any retained or contingent interest in assets transferred to an unconsolidated entity that serves as credit, liquidity or market risk support to such entity. We do not have any variable interest in any unconsolidated entity that provides financing, liquidity, market risk or credit support to us or engages in leasing, hedging or research and development services with us.

B.      Compensation of Directors and Executive Officers

Compensation of directors and executive officers

For the year ended December 31, 2012, the aggregate cash compensation that we paid to our executive officers and directors was approximately $2.1 million. No executive officer is entitled to any severance benefits upon termination of his or her employment with our company.

Share incentive plan

Our board of directors has adopted a 2007 Share Incentive Plan, which is intended to attract and retain the best available personnel for positions of substantial responsibility, provide additional incentive to employees, directors and consultants and promote the success of our business. We have reserved 10,000,000 shares for issuance under our 2007 Share Incentive Plan. The following paragraphs describe the principal terms of our 2007 Share Incentive Plan.

Administration. Our 2007 Share Incentive Plan is administered by our board of directors or, after our board of directors makes the designation, by our compensation committee. In each case, our board of directors or our compensation committee will determine the provisions, terms and conditions of each option grant, including, but not limited to, the option vesting schedule, repurchase provisions, forfeiture provisions, form of payment upon settlement of the award, payment contingencies and satisfaction of any performance criteria.

Awards. The following paragraphs briefly describe the principal features of the various awards that may be granted under our 2007 Share Incentive Plan.

·Options. Options provide for the right to purchase a specified number of our ordinary shares at a specified price and period determined by our compensation committee in one or more installments after the grant date.

·Restricted Shares. A restricted share award is the grant of a specified number of our ordinary shares determined by our compensation committee. A restricted share is subject to restrictions on transferability and other restrictions as our compensation committee may impose. A restricted share may be repurchased by us upon termination of employment or service during a restricted period. Our compensation committee shall also determine in the award agreement whether the participant will be entitled to vote the restricted shares or receive dividends on such shares.

·Restricted Share Units. Restricted share units represent the right to receive a specified number of our ordinary shares at a specified date in the future. On the date specified in the award agreement, we shall deliver to the holder unrestricted ordinary shares which will be freely transferable.

Change of control. If change of control occurs due to third-party acquisition, all outstanding options or share purchase rights may, at the discretion of our compensation committee, be assumed, or equivalent options or rights will be substituted by the successor corporation or parent or subsidiary of successor corporation. In the event that the successor corporation refuses to assume or substitute for the options or share purchase rights, all options or share purchase rights will become fully vested and exercisable and all forfeiture restrictions shall lapse.

Amendment, modification and termination. Unless terminated earlier, our 2007 Share Incentive Plan will expire in 2017. Our board of directors has the authority to amend or terminate our 2007 Share Incentive Plan subject to shareholders’ approval to the extent necessary to comply with applicable laws and regulations. However, no such action may materially adversely affect any awards previously granted pursuant to our 2007 Share Incentive Plan without the prior written consent of the plan participants.

Share options

The following paragraphs describe the principal terms of our options.

Option agreement. Options granted under our 2007 Share Incentive Plan are evidenced by an option agreement that contains, among other things, provisions concerning exercisability and forfeiture upon termination of employment or consulting arrangement, as determined by our board.

Vesting schedule. Options granted under our 2007 Share Incentive Plan vest over a two-year period following a specified vesting commencement date. 50% of the options granted vest at the first anniversary of the grant date and the remaining 50% shall vest at the secondary anniversary of the grant date, subject to the optionee continuing to be an employee or a service provider on each vesting date.

Option exercise. The term of options granted under our 2007 Share Incentive Plan may not exceed three years from the date of vesting.

Termination of options. Where the option agreement permits the exercise of the options that were vested before the recipient’s termination of service with us, or the recipient’s disability or death, the options will terminate to the extent not exercised or purchased on the last day of a specified period or the last day of the original term of the options, whichever occurs first.

In August 2007, we granted certain of our officers, employees and consultants options to purchase 5,206,000 of our ordinary shares. All of these options expired in August 24, 2012.

C.     Board Practices

There are no severance benefits payable to our directors upon termination of their directorships.

Committees of the board of directors

Special committee

See “Item 4. Information on the Company—A. History and Development of the Company.”

Code of business conduct and ethics

Our code of business conduct and ethics provides that our directors and officers are expected to avoid any action, position or interest that conflicts with the interests of our company or gives the appearance of a conflict. Directors and officers have an obligation under our code of business conduct and ethics to advance our company’s interests when the opportunity to do so arises.

72

Duties of directors

Under Cayman Islands law, our directors have a duty of loyalty to act honestly and in good faith, with a view to our best interests. Our directors also have a duty to exercise the skill they possess with such care and diligence that a reasonably prudent person would exercise in comparable circumstances. In fulfilling their duty of care, our directors must ensure compliance with our memorandum and articles of association. We have the right to seek damages if a duty owed by our directors is breached. If a director has a personal interest in a matter before the board of directors of our company, the director will disclose such interest to the board of directors, excuse himself or herself from the discussion of the matter and will not take part in the vote on the matter.

Terms of directors and officers

In accordance with our articles of association, all directors are eligible for re-election once every three years. At each annual general meeting, one-third of our directors (or, if their number is not a multiple of three, the number nearest to but not less than one-third) will retire from office by rotation. A retiring director shall be eligible for re-election and shall continue to act as a director at the meeting during which he has proposed his retirement. The directors to retire by rotation shall include any director who wishes to retire and not to offer himself for re-election. Any other directors subject to retirement shall be those who have been longest in office since their last re-election or appointment. In addition, a director must vacate his directorship if he resigns, becomes mentally unsound or dies, is absent from board meetings for six consecutive months without special leave from our board, becomes bankrupt or ceases to be a director under the law or is removed by our shareholders. A director may be removed by an ordinary resolution of our shareholders. Officers are selected by and serve at the discretion of the board of directors. The compensation of our directors is determined by the board of directors. There is no mandatory retirement age for directors.

Employment agreements

We have entered into employment agreements with each of our executive officers. Under some of these agreements there is a specified period of employment, while under others there is not. We may terminate the employment for cause, at any time, without notice or remuneration, for certain acts of the executive officer, including but not limited to a conviction of a criminal offense involving integrity or honesty, being guilty of fraud, gross misconduct, or gross incompetence or unsatisfactory or poor performance after receiving a written warning. An executive officer may terminate his employment at any time by giving the company a specified period of written notice or payment in lieu of notice, and under most agreements neither party may terminate for 36 months absent good reason. These agreements do not provide for any special termination benefits, nor do we have other arrangements with these executive officers for special termination benefits.

Each executive officer has agreed to hold, both during and after the employment agreement expires or is terminated, in strict confidence and not to use, except as required in the performance of his duties in connection with the employment with our company, any confidential information, technical data, trade secrets and know-how of our company or the confidential information of any third party, including our subsidiaries, received by us. The executive officers have also agreed to disclose in confidence to us all inventions, designs and trade secrets which they conceive, develop or reduce to practice and that they shall be our absolute property. In addition, each executive officer has agreed to be bound by the non-competition restrictions set forth in his or her employment agreement. Specifically, each executive officer has agreed, while being employed by us and for a period of one year after termination of his or her employment, not to:

·solicit business from or perform services for any person who was a client, customer, supplier or prospective client of ours or of our subsidiaries during the executive officers’ employment;

·solicit or induce any person to terminate his or her employment or consulting relationship with us or our subsidiaries; or

·engage, invest or assist in any business that competes with our existing or future business or our subsidiaries.

Each of the executive officer’s employment may be terminated for cause if the employee is convicted or pleads guilty to a crime which the board reasonably believes has had or will have a detrimental effect on us, the employee has been negligent or acted dishonestly to our detriment, the employee continues to engage in misconduct or fails to perform his/her required duties despite opportunity for cure, the employee has died or has a disability for more than 180 days in any 12-month period. In addition, we may terminate the employment without cause, at any time, upon one month written notice.

The excess of the VAT export rebate, if any, over the expenses as indicated above was kept by Wuxi Eastar as profit. The purchases of accessories and machinery from Wuxi Eastar were $2.5 million, at prices exclusive of VAT with a markup of 3% charged by Wuxi Eastar.

Based on a building lease agreement dated June 19, 2006 and subsequently amended, WSP China has rented from Wuxi Longhua a piece of land and certain buildings located in Wuxi, China for production and storing purposes, for which we paid $805,000, $844,000 and $119,000 in 2010, 2011 and 2012, respectively. The lease initially expired on August 31, 2009, and has been renewed for one-year terms, with the latest expiration date being December 31, 2013.

In view of the purpose and nature of the transactions, we accounted for them as financing transactions with the banks in our financial statements. See “Item 5.

Legal proceedings

In April 2009, seven U.S. companies and the United Steelworkers Union filed a petition with the International Trade Commission and the Department of Commerce, alleging that China based OCTG manufacturers unfairly dumped OCTG products in the U.S. market and that Chinese producers were benefitting from massive government subsidies. We were named as one of the major exporters of OCTG products from China and included as one of the mandatory respondent companies to the United States government’s countervailing duty investigation. On September 8, 2009, a preliminary determination was issued with a countervailing duty rate of 24.92% assigned to us. On December 7, 2009, the DOC published its final determination in the countervailing duties investigation with a rate of 14.61% assigned to WSP China. The rate was subsequently changed to 14.95% in January 2010 due to certain ministerial errors made by the DOC.

WSP China was not classified as a mandatory respondent to the anti-dumping investigation and participated in this case as a separate rate respondent. In November 2009, we received a preliminary anti-dumping rate of 36.53% which was based on the average dumping rates of other OCTG producers that were selected as mandatory respondents. In December 2009, this rate was amended to 96.51%, due to certain ministerial errors made by the DOC. On April 9, 2010, the DOC announced its final determination in the anti-dumping investigation with a rate of 29.94% assigned to WSP China. In May 2010, the ITC made a final ruling which requires all Chinese exports of OCTG products to the United States, including WSP China’s products, be charged up to about 32.07% anti-dumping duties and 14.95% countervailing duties.

The anti-dumping and countervailing duties are applied to all Chinese exports of OCTG products to the United States starting from the date of the DOC’s preliminary determinations. WSP China did not export OCTG products to the United States in 2009 and 2010 after the date of the DOC’s preliminary determinations. The anti-dumping and countervailing duties will apply to us if WSP China exports OCTG products to the United States in the future and we are not subject to any other penalties or fines.

In December 2008, SB International, Inc., a Texas corporation, brought a case against us, Houston OCTG, WSP China, Mr. Longhua Piao and certain other individuals in the District Court of Dallas County, Texas, alleging that the defendants interfered with the plaintiff’s contracts and business relations with its customers. The petition also contained claims for theft of information, conversion, breach of fiduciary duty, misappropriation of confidential information, fraud and conspiracy. There is no specific amount of damages claimed in the petition. We filed a counterclaim against SB International, Inc. and certain other plaintiffs, requesting for declaratory judgment and claims for breach of fiduciary duty, negligence, constructive fraud, request for accounting and breach of contract. In February 2011, this case was settled for $7.8 million.

In May 2007, Frank H. Migl and several other plaintiffs brought a lawsuit against Watson Pipe, Inc., Atlas Tubular, L.P., Halliburton Energy Services, Inc. and Xxtreme Inspection in the District Court of Lavaca County, Texas. The plaintiffs alleged that a casing pipe ruptured in one of plaintiffs’ oil and gas wells, which caused over $7.0 million in damages. In 2008, the plaintiffs amended the petition to add WSP China as a defendant, and one of the defendants filed a petition against WSP China as third-party defendant, alleging that WSP China supplied the defective products for the operation. In January 2011, this case was settled for $0.8 million.

In December 2009, Dewbre Petroleum Corporation, as the plaintiff, brought a lawsuit against SB International, Inc., Tubular Synergy Group, LP, Padre Tubular Resources, Inc. and Xxtreme Pipe Storage, LLC in the District Court of Nueces County, Texas. The plaintiff alleged that a defective pipe caused damage to its well. In January 2010, the plaintiffs amended the petition to add WSP China as a defendant, alleging that WSP China supplied the defective pipe. The plaintiff claimed total damages in the amount of approximately $20.8 million. In May 2011, this case was settled for $4.3 million.

In August 2009, Western Oil and Gas Development Corp., as the plaintiff, brought a lawsuit against WSP China, J&B Pipe Supply, Inc., SB International, Inc. and certain other party in the District Court of Canadian County, Oklahoma. The plaintiff alleged that a casing pipe provided by WSP China caused damage to its well. The plaintiff claimed total damages in the amount of approximately $9.5 million. J&B Pipe Supply, Inc. and SB International, Inc. have filed cross claims against WSP China for indemnification and breach of warranty. In June 2011, this case was settled for $4.5 million.

In April 2010, Penn Virginia Oil & Gas, L.P., as the plaintiff, brought a lawsuit against WSP China and certain other parties in the District Court of Panola County, Texas, alleging that WSP China supplied a defective casing pipe, which caused a failed operation in an oil and gas well. The plaintiff claimed total damages in the amount of approximately $4.8 million. In January 2011, this case was settled for $2.3 million.

78

In May 2010, Chesapeake Energy Corporation and certain other parties, as the plaintiffs, brought a lawsuit against WSP China and certain other parties in the District Court of Desoto Parish, Louisiana, alleging that WSP China supplied a defective casing pipe, which caused a failed operation in an oil and gas well. We intend to vigorously defend ourselves against the claims. The plaintiffs claimed total damages in the amount of approximately $15.0 million. The trial date for this case has not been set. In connection with this case, certain landowners who were affected by the failed oil and gas well operation mentioned above filed a lawsuit against Chesapeake Energy Corporation in the District Court of Desoto Parish, Louisiana in November 2009. Such landowners claimed damages up to $50,000 for each of them and their minor children in a group of 36 individuals. In May 2010, the landowners amended the petition to name WSP China as a co-defendant in the lawsuit. In October 2012, the case was settled for $13,300.

In connection with a lawsuit brought by Mewbourne Oil Company against Trident Steel Corporation for selling defective casing pipes, in August 2010, Trident Steel Corporation filed a third-party petition against Minmetals, Inc. and WSP China in the District Court of Lipscomb County, Texas, stating that it fulfilled the Mewbourne Oil Company’s purchase order using the casing pipes manufactured by Minmetals, Inc. and WSP China. We have had settlement discussions regarding this lawsuit, but Mewbourne Oil Company’s settlement demands have been in excess of $2 million. The trial date for this case has been set for December 2, 2013.

In March 2011, Cimarex Energy Co. filed a lawsuit against us, WSP China, Houston OCTG and other defendants in Nueces County, Texas, seeking total damages in the amount of $11.0 million resulting from defects in casing pipes provided by us. In March 2012, this case was settled for $5.0 million.

In 2011, 2012 and 2013, a number of our suppliers filed lawsuits against our subsidiaries Wuxi Seamless, Bazhou Seamless and Mengfeng seeking past due payments for raw materials and services that we have purchased from them and additional damages. The total of these past due amounts and damages is estimated to be approximately RMB86.0 million ($14.0 million), of which RMB17.1 million ($2.8 million) have already been settled. As a result of these claims and lawsuits, certain of our bank accounts and assets were frozen by court order.

In August 2013, Energy Holdings, Inc. and Texas Energy Operations, LC brought a lawsuit against WSP Holdings, WSP China, Houston OCTG, J&B Tubular Pipe Supply, Inc., Texas Tubular Sales, LP, and National Oilwell Varco, LP d/b/a NOV Tuboscope in a district court in Dallas County, Texas. Plaintiffs brought suit against defendants for improper manufacture, sales and ultimate failure of oil and gas well casing that the plaintiffs installed in the Gibbons #1 well in Jackson County, Oklahoma. Substantial discovery will take place in 2014 and the potential liability will be assessable as the discovery in the case proceeds.

Except as disclosed above, we are not currently a party to any other material legal or administrative proceedings. However, we are, from time to time, a party to various legal or administrative proceedings arising in the ordinary course of our business.

Dividend policy

From time to time, we have paid dividends to shareholders. We declared a dividend of $15.0 million in January 2005, which was in turn contributed by our shareholders to increase the registered capital of WSP China. We declared dividends in aggregate of $28.8 million in June 2006 and August 2006 and $32.5 million in October 2007. In March 2009, we declared a cash dividend in the amount of $0.15 per ordinary share, or $1.50 per ADS, and a one-time special cash dividend in the amount of $0.225 per ordinary share, or $2.25 per ADS, out of our annual profits for the years ended December 31, 2007 and 2008.

In March 2009, our board also approved our dividend policy to declare annual dividend in the range of 30% to 50% of our annual profit going forward. Our board of directors has complete discretion on whether to pay dividends, subject to the approval of our shareholders. Even if our board of directors decides to pay dividends, the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that our board of directors may deem relevant. The timing and amount of dividend payments are subject to the discretion of our board of directors and is dependent upon various factors, including our cash flow and working capital requirements, as well as the withholding tax obligations under the New EIT Law. Depending on future events and other changes in the regulatory environment or the business climates, our board of directors may determine at a later time to change our dividend policy.

Cash dividends on our ADSs, if any, will be paid in U.S. dollars.

B.     Memorandum and Articles of Association

The following are summaries of the material provisions of our amended and restated memorandum and articles of association, as well as the Companies Law (2011 Revision) of the Cayman Islands, which is referred to as the Companies Law below, in so far as they relate to the material terms of our shares. This summary is not complete, and you should read our amended and restated memorandum and articles of association.

Registered Office

Our registered office is located at the offices of Codan Trust Company (Cayman) Limited, Cricket Square, Hutchins Drive, P.O. Box 2681, Grand Cayman, KY1-1111, Cayman Islands.

Objects

Our amended and restated memorandum of association states that the objects for which the Company is established are unrestricted, and that the Company shall have and be capable of exercising all the functions of a natural person of full capacity irrespective of any question of corporate benefit, as provided in section 27(2) of the Companies Law and in view of the fact that the Company is an exempted company that the Company will not trade in the Cayman Islands with any person, firm or corporation except in furtherance of the business of the Company carried on outside the Cayman Islands.

Board of Directors

See “Item 6. Directors, Senior Management and Employees—C. Board Practices—Board of directors.”

Meetings

Subject to the company’s regulatory requirements, an annual general meeting and any extraordinary general meeting shall be called by not less than ten clear days’ notice in writing. Notice of every general meeting will be given to all of our shareholders other than those that, under the provisions of our amended and restated articles of association or the terms of issue of the ordinary shares they hold, are not entitled to receive such notices from us, and also to our principal external auditors. Extraordinary general meetings may be called only by the chairman of our board of directors or a majority of our board of directors, and may not be called by any other person.

Notwithstanding that a meeting is called by a shorter notice than that mentioned above, but, subject to applicable regulatory requirements, it will be deemed to have been duly called, if it is so agreed (1) in the case of a meeting called as an annual general meeting by all of our shareholders entitled to attend and vote at the meeting; (2) in the case of any other meeting, by a majority in number of our shareholders having a right to attend and vote at the meeting, being a majority together holding not less than 95% in nominal value of the ordinary shares giving that right.

81

Two shareholders present in person or by proxy (in the case of a shareholder being a corporation, by its duly authorized representative) that represent not less than one-third in nominal value of our total issued and outstanding voting shares will constitute a quorum. No business other than the appointment of a chairman may be transacted at any general meeting unless a quorum is present at the commencement of business. If present, the chairman of our board of directors shall be the chairman presiding at any shareholders meetings.

A corporation being a shareholder shall be deemed for the purpose of our amended and restated articles of association to be present in person if represented by its duly authorized representative being the person appointed by resolution of the directors or other governing body of such corporation to act as its representative at the relevant general meeting or at any relevant general meeting of any class of our shareholders. Such duly authorized representative shall be entitled to exercise the same powers on behalf of the corporation that he represents as that corporation could exercise if it were our individual shareholder.

The quorum for a separate general meeting of the holders of a separate class of shares is described in “—Modification of Rights” below.

Voting rights attaching to the shares

Subject to any special rights or restrictions as to voting for the time being attached to any shares, at any general meeting on a show of hands every shareholder who is present in person or by proxy (or, in the case of a shareholder being a corporation, by its duly authorized representative) shall have one vote, and on a poll every shareholder present in person or by proxy (or, in the case of a shareholder being a corporation, by its duly appointed representative) shall have one vote for each fully paid share of which such shareholder is the holder.

No shareholder shall be entitled to vote or be reckoned in a quorum, in respect of any share, unless such shareholder is registered as our shareholder at the applicable record date for that meeting and all calls or installments due by such shareholder to us have been paid.

If a recognized clearing house or depositary (or its nominee(s)) is our shareholder, it may authorize such person or persons as it thinks fit to act as its representative(s) at any meeting or at any meeting of any class of shareholders provided that, if more than one person is so authorized, the authorization shall specify the number and class of shares in respect of which each such person is so authorized. A person authorized pursuant to this provision is entitled to exercise the same powers on behalf of the recognized clearing house or depositary (or its nominee(s)) as if such person was the registered holder of our shares held by that clearing house or depositary (or its nominee(s)) including the right to vote individually on a show of hands.

Protection of minority shareholders

The Grand Court of the Cayman Islands may, on the application of shareholders holding not less than one fifth of our shares in issue, appoint an inspector to examine our affairs and to report thereon in a manner as the Grand Court shall direct.

Any shareholder may petition the Grand Court of the Cayman Islands that may make a winding up order, if the court is of the opinion that it is just and equitable that we should be wound up, or, as an alternative to a winding up order, (a) an order regulating the conduct of our affairs in the future, (b) an order requiring us to refrain from doing or continuing an act complained of by the shareholder petitioner or to do an act which the shareholder petitioner has complained it has omitted to do, (c) an order authorising civil proceedings to be brought in our name and on our behalf by the shareholder petitioner on such terms as the Court may direct, or (d) an order providing for the purchase of the shares of any of our shareholders by other shareholders or us and, in the case of a purchase by us, a reduction of our capital accordingly.

Claims against us by our shareholders must, as a general rule, be based on the general laws of contract or tort applicable in the Cayman Islands or their individual rights as shareholders as established by our amended and restated memorandum and articles of association.

The Cayman Islands courts ordinarily would be expected to follow English case law precedents which permit a minority shareholder to commence a representative action against, or derivative actions in our name to challenge (1) an act which is ultra vires or illegal, (2) an act which constitutes a fraud against the minority and the wrongdoers are themselves in control of us, and (3) an irregularity in the passing of a resolution which requires a qualified (or special) majority.

82

Pre-emption rights

There are no pre-emption rights applicable to the issue of new shares under either Cayman Islands law or our amended and restated memorandum and articles of association.

Liquidation rights

Subject to any special rights, privileges or restrictions as to the distribution of available surplus assets on liquidation for the time being attached to any class or classes of shares (1) if we are wound up and the assets available for distribution among our shareholders are more than sufficient to repay the whole of the capital paid up at the commencement of the winding up, the excess shall be distributed pari passu among those shareholders in proportion to the amount paid up at the commencement of the winding up on the shares held by them, respectively and (2) if we are wound up and the assets available for distribution among the shareholders as such are insufficient to repay the whole of the paid-up capital, those assets shall be distributed so that, as nearly as may be, the losses shall be borne by the shareholders in proportion to the capital paid up at the commencement of the winding up on the shares held by them, respectively.

If we are wound up, the liquidator may with the sanction of our special resolution and any other sanction required by the Companies Law, divide among our shareholders in specie or kind the whole or any part of our assets (whether they shall consist of property of the same kind or not) and may, for such purpose, set such value as the liquidator deems fair upon any property to be divided and may determine how such division shall be carried out as between the shareholders or different classes of shareholders. The liquidator may also vest the whole or any part of these assets in trustees upon such trusts for the benefit of the shareholders as the liquidator shall think fit, but so that no shareholder will be compelled to accept any assets, shares or other securities upon which there is a liability.

Modification of rights

Except with respect to share capital (as described below) and the location of the registered office, alterations to our amended and restated memorandum and articles of association may only be made by special resolution, meaning a majority of not less than two-thirds of votes cast at a shareholders meeting.

Subject to the Companies Law, all or any of the special rights attached to shares of any class (unless otherwise provided for by the terms of issue of the shares of that class) may be varied, modified or abrogated with the sanction of a special resolution passed at a separate general meeting of the holders of the shares of that class. The provisions of our amended and restated articles of association relating to general meetings shall apply similarly to every such separate general meeting, but so that the quorum for the purposes of any such separate general meeting or at its adjourned meeting shall be a person or persons together holding (or represented by proxy) on the date of the relevant meeting not less than one-third in nominal value of the issued shares of that class, every holder of shares of the class shall be entitled on a poll to one vote for every such share held by such holder and that any holder of shares of that class present in person or by proxy may demand a poll.

The special rights conferred upon the holders of any class of shares shall not, unless otherwise expressly provided in the rights attaching to or the terms of issue of such shares, be deemed to be varied by the creation or issue of further shares ranking pari passu therewith.

Alteration of capital

We may from time to time by ordinary resolution:

·increase our capital by such sum, to be divided into shares of such amounts, as the resolution shall prescribe;

·consolidate and divide all or any of our share capital into shares of larger amount than our existing shares;

·cancel any shares which at the date of the passing of the resolution have not been taken or agreed to be taken by any person, and diminish the amount of its share capital by the amount of the shares so cancelled subject to the provisions of the Companies Law;

·sub-divide our shares or any of them into shares of smaller amount than is fixed by our amended and restated memorandum of association, subject nevertheless to the Companies Law, and so that the resolution whereby any share is sub-divided may determine that, as between the holders of the shares resulting from such subdivision, one or more of the shares may have any such preferred or other special rights, over, or may have such deferred rights or be subject to any such restrictions as compared with the others as we have power to attach to unissued or new shares; and

·divide shares into several classes and without prejudice to any special rights previously conferred on the holders of existing shares, attach to the shares respectively any preferential, deferred, qualified or special rights, privileges, conditions or such restrictions that in the absence of any such determination in general meeting may be determined by our directors.

83

We may, by special resolution, subject to any confirmation or consent required by the Companies Law, reduce our share capital or any capital redemption reserve in any manner authorized by law.

Transfer of shares

Subject to any applicable restrictions set forth in our amended and restated articles of association, any of our shareholders may transfer all or any of his or her shares by an instrument of transfer in the usual or common form or in a form prescribed by the NYSE or in any other form that our directors may approve.

Our directors may decline to register any transfer of any share which is not paid up or on which we have a lien. Our directors may also decline to register any transfer of any share unless:

·the instrument of transfer is lodged with us accompanied by the certificate for the shares to which it relates and such other evidence as our directors may reasonably require to show the right of the transferor to make the transfer;

·the instrument of transfer is in respect of only one class of share;

·the instrument of transfer is properly stamped (in circumstances where stamping is required); and

·a fee of such maximum sum as the New York Stock Exchange may determine to be payable or such lesser sum as our directors may from time to time require is paid to us in respect thereof.

If our directors refuse to register a transfer they shall, within two months after the date on which the instrument of transfer was lodged, send to each of the transferor and the transferee notice of such refusal.

The registration of transfers may, on notice being given by advertisement in such one or more newspapers or by any other means in accordance with the requirements of the New York Stock Exchange, be suspended and the register closed at such times and for such periods as our directors may from time to time determine; provided, however, that the registration of transfers shall not be suspended nor the register closed for more than 30 days in any year as our directors may determine.

Share repurchase

We are empowered by the Companies Law and our amended and restated articles of association to purchase our own shares, subject to certain restrictions. Our directors may only exercise this power on our behalf, subject to the Companies Law, our amended and restated memorandum and articles of association and to any applicable requirements imposed from time to time by the New York Stock Exchange, the SEC, or by any other recognized stock exchange on which our securities are listed.

Dividends

Subject to the Companies Law, we may in a general meeting declare dividends in any currency to be paid to our shareholders. Dividends may be declared and paid out of our profits, realized or unrealized, or from any reserve set aside from profits which our directors determine is no longer needed. Our board of directors may also declare and pay dividends out of the share premium account or any other fund or account that can be authorized for this purpose in accordance with the Companies Law.

Except in so far as the rights attaching to, or the terms of issue of, any share otherwise provides (1) all dividends shall be declared and paid according to the amounts paid up on the shares in respect of which the dividend is paid, but no amount paid up on a share in advance of calls shall be treated for this purpose as paid up on that share and (2) all dividends shall be apportioned and paid pro rata according to the amounts paid upon the shares during any portion or portions of the period in respect of which the dividend is paid.

84

Our directors may also pay any dividend that is payable on any shares semi-annually or on any other dates, whenever our financial position, in the opinion of our directors, justifies such payment.

Our directors may deduct from any dividend or bonus payable to any shareholder all sums of money (if any) presently payable by such shareholder to us on account of calls, installments or otherwise.

No dividend or other money payable by us on or in respect of any share shall bear interest against us.

In respect of any dividend proposed to be paid or declared on our share capital, our directors may resolve and direct that (1) such dividend be satisfied wholly or in part in the form of an allotment of shares credited as fully paid up, provided that our members entitled thereto will be entitled to elect to receive such dividend (or part thereof if our shareholders so determine) in cash in lieu of such allotment or (2) the shareholders entitled to such dividend will be entitled to elect to receive an allotment of shares credited as fully paid up in lieu of the whole or such part of the dividend as our directors may think fit. We may also, on the recommendation of our directors, resolve in respect of any particular dividend that, notwithstanding the foregoing, it may be satisfied wholly in the form of an allotment of shares credited as fully paid up without offering any right of shareholders to elect to receive such dividend in cash in lieu of such allotment.

Any dividend interest or other sum payable in cash to the holder of shares may be paid by check or warrant sent by mail addressed to the holder at his registered address, or addressed to such person and at such addresses as the holder may direct. Every check or warrant shall, unless the holder or joint holders otherwise direct, be made payable to the order of the holder or, in the case of joint holders, to the order of the holder whose name stands first on the register in respect of such shares, and shall be sent at his or their risk and payment of the check or warrant by the bank on which it is drawn shall constitute a good discharge to us.

All dividends unclaimed for one year after having been declared may be invested or otherwise made use of by our board of directors for the benefit of our company until claimed. Any dividend unclaimed after a period of six years from the date of declaration of such dividend may be forfeited by our board of directors and, if so forfeited, shall revert to us.

Whenever our directors or our shareholders in a general meeting have resolved that a dividend be paid or declared, our directors may further resolve that such dividend be satisfied wholly or in part by the distribution of specific assets of any kind, and in particular, of paid up shares, debentures or warrants to subscribe for our securities or securities of any other company. Where any difficulty arises with regard to such distribution, our directors may settle it as they think expedient. In particular, our directors may issue fractional certificates, ignore fractions altogether or round the same up or down, fix the value for distribution purposes of any such specific assets, determine that cash payments shall be made to any of our shareholders upon the footing of the value so fixed in order to adjust the rights of the parties, vest any such specific assets in trustees as may seem expedient to our directors, and appoint any person to sign any requisite instruments of transfer and other documents on behalf of a person entitled to the dividend, which appointment shall be effective and binding on our shareholders.

Untraceable shareholders

We are entitled to sell any shares of a shareholder who is untraceable, provided that:

·all checks or warrants in respect of dividends of such shares, not being less than three in number, for any sums payable in cash to the holder of such shares have remained un-cashed for a period of 12 years prior to the publication of the advertisement and during the three months referred to in third bullet point below;

·we have not during that time received any indication of the whereabouts or existence of the shareholder or person entitled to such shares by death, bankruptcy or operation of law; and

·we have caused an advertisement to be published in newspapers in the manner stipulated by our amended and restated articles of association, giving notice of our intention to sell these shares, and a period of three months has elapsed since such advertisement and the New York Stock Exchange has been notified of such intention.

The net proceeds of any such sale shall belong to us, and when we receive these net proceeds we shall become indebted to the former shareholder for an amount equal to such net proceeds.

85

C.     Material Contracts

We have not entered into any material contracts other than in the ordinary course of business and other than those described in “Item 4. Information on the Company” or elsewhere in this annual report.

D.     Exchange Controls

E.      Taxation

People’s Republic of China taxation

Prior to January 1, 2008, under the Income Tax Law for Enterprises with Foreign Investment and Foreign Enterprises then in effect, any dividends payable to non-PRC investors were exempt from any PRC withholding tax. In addition, under the then effective PRC laws, any dividends payable, or distributions made by us to holders or beneficial owners of our ADSs were not subject to any PRC tax, provided that the holders or beneficial owners have not been physically resident in China for a period of one year or more and have not become subject to PRC tax.

In March 2007, the PRC National People’s Congress passed the New EIT Law, and in December 2007, the State Council promulgated the implementing rules of the New EIT Law, both of which became effective on January 1, 2008. Under the New EIT Law, enterprises established under the laws of non-PRC jurisdictions, but whose de facto management body is located in China, may be treated as resident enterprises for PRC tax purposes. The New EIT Law and its implementing rules are relatively new and ambiguous in terms of some definitions, requirements and detailed procedures, and currently no official interpretation or application of this new resident enterprise classification is available. Therefore, it is unclear as to how tax authorities will determine tax residency based on the facts of each case. All of our management members reside in China. If WSP Holdings or FSHL is treated as a resident enterprise for PRC tax purposes, their worldwide income will be subject to PRC income tax at the 25% uniform tax rate, which will include any dividend income we receive from our subsidiaries, unless such dividend income is otherwise exempted from taxable income under the New EIT Law.

Moreover, the New EIT Law and its implementing rules provide that an income tax rate of 10% will be applicable to dividends payable to non-PRC shareholders that are derived from sources within China, unless a tax treaty exists between China and the relevant jurisdictions where such non-PRC shareholders reside and such treaty provides for a reduction or exemption of the relevant tax. We are a Cayman Islands holding company and our income mainly comes from dividends we receive from our subsidiaries, primarily from those located in the PRC. Since the New EIT Law and its implementing rules are relatively new and ambiguous in certain aspects, there is uncertainty as to how this New EIT Law will be implemented and whether the dividends we pay to our non-PRC shareholders will be subject to the 10% income tax. If we are required under the New EIT Law to withhold PRC income tax on such dividends, your investment in our ADSs may be materially and adversely affected. In addition, in 2009, FSHL was recognized by relevant tax authorities as a tax resident company in the Hong Kong Special Administrative Region. As a result, a withholding tax at 5% will be applicable on China dividends paid to FSHL.

Cayman Islands taxation

The Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciations and there is no taxation in the nature of inheritance tax or estate duty or withholding tax applicable to us or to any holder of ADSs or ordinary shares. There are no other taxes likely to be material to us levied by the Government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or after execution brought within the jurisdiction of the Cayman Islands. No stamp duty is payable in the Cayman Islands on transfers of shares of Cayman Islands companies except those which hold interests in land in the Cayman Islands. The Cayman Islands is not party to any double tax treaties. There are no exchange control regulations or currency restrictions in the Cayman Islands.

Pursuant to Section 6 of the Tax Concessions Law (1999 Revision) of the Cayman Islands, we have obtained an undertaking from the Governor-in-Cabinet:

·that no law which is enacted in the Cayman Islands imposing any tax to be levied on profits or income or gains or appreciations shall apply to our company or its operations; and

·that the aforesaid tax or any tax in the nature of estate duty or inheritance tax shall not be payable on the shares, debentures or other obligations of our company.

86

The undertaking for us is for a period of twenty years from December 12, 2006.

United States federal income taxation

The following discussion describes the material U.S. federal income tax consequences under present law to U.S. Holders (defined below) of an investment in the ADSs or ordinary shares. This discussion applies only to U.S. Holders that hold the ADSs or ordinary shares as capital assets and that have the U.S. dollar as their functional currency. This discussion is based on the federal income tax laws of the United States as in effect on the date of this annual report and on U.S. Treasury regulations in effect or, in some cases, proposed, as of the date of this annual report, as well as judicial and administrative interpretations thereof available on or before such date. All of the foregoing authorities are subject to change, which change could apply retroactively and could affect the tax consequences described below.

The following discussion does not deal with the tax consequences to any particular investor or to persons in special tax situations such as:

·banks;

·certain financial institutions;

·insurance companies;

·broker dealers;

·traders that elect to mark to market;

·tax-exempt entities;

·persons liable for alternative minimum tax;

·persons holding an ADS or ordinary share as part of a straddle, hedging, conversion or integrated transaction;

·persons who acquired ADSs or ordinary shares pursuant to the exercise of any employee stock options or otherwise as compensation;

·persons that actually or constructively own 10% or more of our voting stock; or

·persons holding ADSs or ordinary shares through partnerships or other pass-through entities.

INVESTORS ARE URGED TO CONSULT THEIR TAX ADVISORS ABOUT THE APPLICATION OF THE U.S. FEDERAL TAX RULES TO THEIR PARTICULAR CIRCUMSTANCES AS WELL AS THE STATE AND LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF ADSS OR ORDINARY SHARES.

The discussion below of the U.S. federal income tax consequences to “U.S. Holders” will apply if you are the beneficial owner of ADSs or ordinary shares and you are, for U.S. federal income tax purposes:

·an individual who is citizen or resident of the United States;

·a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) organized under the laws of the United States, any State or the District of Columbia;

·an estate whose income is subject to U.S. federal income taxation regardless of its source; or

·a trust that (1) is subject to the primary supervision of a court within the United States and the control of one or more U.S. persons or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

87

The discussion below does not address the consequences of the recently enacted Medicare tax on “net investment income.” In addition, if you are a partner in a partnership or other entity taxable as a partnership that holds ADSs or ordinary shares, your tax treatment generally will depend on your status and the activities of the partnership.

The discussion below assumes that the representations contained in the deposit agreement are true and that the obligations in the deposit agreement and any related agreement will be complied with in accordance with their terms. If you hold ADSs, you should be treated as the holder of the underlying ordinary shares represented by those ADSs for U.S. federal income tax purposes.

The U.S. Treasury has expressed concerns that intermediaries in the chain of ownership between the holder of an ADS and the issuer of the security underlying the ADS may be taking actions that are inconsistent with the beneficial ownership of the underlying shares (for example, pre-releasing ADSs to persons who do not have the beneficial ownership of the securities underlying the ADSs). Accordingly, the availability of the reduced tax rate for dividends received by non-corporate U.S. Holders, including individuals, (discussed below) could be affected by actions taken by intermediaries in the chain of ownership between the holder of ADSs and our company if as a result of such actions the holders of ADSs are not properly treated as beneficial owners of underlying shares.

Taxation of dividends and other distributions on the ADSs or ordinary shares

Subject to the passive foreign investment company rules discussed below, the gross amount of our distributions to you with respect to the ADSs or ordinary shares, including any amounts withheld with respect to PRC taxes, generally will be included in your gross income as dividend income on the date of actual or constructive receipt by the depositary, in the case of ADSs, or by you, in the case of ordinary shares, to the extent that the distribution is paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). To the extent that the amount of the distribution exceeds our current and accumulated earnings and profits (determined under U.S. federal income tax principles), it will be treated first as a tax-free return of your tax basis in your ADSs or ordinary shares, and to the extent the amount of the distribution exceeds your tax basis, the excess will be taxed as capital gain. We do not intend to calculate our earnings and profits under U.S. federal income tax principles. Therefore, a U.S. Holder should expect that a distribution will generally be reported as a dividend even if that distribution would otherwise be treated as a non-taxable return of capital or as capital gain under the rules described above. Such dividends will not be eligible for the dividends-received deduction allowed to corporations in respect of dividends received from other U.S. corporations.

With respect to non-corporate U.S. Holders, including individual U.S. Holders, dividends may be taxed as qualified dividend income at the lower applicable capital gains rate provided that specified conditions are satisfied, including (1) the ADSs or ordinary shares, as applicable, are readily tradable on an established securities market in the United States, (2) we are not a passive foreign investment company (as discussed below) with respect to the U.S. Holder for either our taxable year in which the dividend is paid or the preceding taxable year, and (3) such holder meets specified holding period and other requirements. We expect the ADSs will continue to be listed on the New York Stock Exchange, and if so, the ADSs will be treated as readily tradable on an established securities market in the United States for purposes of clause (1). You should consult your tax advisors regarding the availability of the lower rate for dividends paid with respect to our ADSs or ordinary shares, as well as the effects of any change in applicable law after the date of this annual report.

Dividends generally will constitute foreign source income for foreign tax credit limitation purposes. If the dividends are qualified dividend income (as discussed above), the amount of the dividend taken into account for purposes of calculating the foreign tax credit limitation will in general be limited to the gross amount of the dividend, multiplied by the reduced applicable rate divided by the highest rate of tax normally applicable to dividends. PRC taxes withheld from dividends on the ADSs or ordinary shares at a rate not exceeding the rate provided for in the treaty between China and the United States will be creditable against your US federal income tax liability, subject to applicable restrictions and limitations that may vary depending upon your individual circumstances. Instead of claiming a credit, you generally may elect to deduct such PRC taxes in computing your taxable income, subject to generally applicable limitations. Such election would then apply to all of your applicable foreign taxes. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For this purpose, dividends distributed by us with respect to the ADSs or ordinary shares will generally constitute “passive category income” but could, in the case of some U.S. Holders, constitute “general category income.” The rules governing foreign tax credits are complex. Therefore, you should consult you own tax advisors regarding the availability of foreign tax credits in your particular circumstances.

88

Taxation of disposition of ADSs or ordinary shares

Subject to the passive foreign investment company rules discussed below, you will recognize capital gain or loss on any sale, exchange or other taxable disposition of an ADS or ordinary share equal to the difference between the amount realized for the ADS or ordinary share and your tax basis in the ADS or ordinary share. If you are a non-corporate U.S. holder, including an individual U.S. Holder, you may be eligible for reduced tax rates if you have held the ADSs or ordinary shares for more than a year. The deductibility of capital losses is subject to limitations. Any such gain or loss that you recognize will generally be treated as U.S. source income or loss for foreign tax credit limitation purposes, subject to exceptions and limitations.

Passive foreign investment company

Based on the market price of our ADSs, the value of our assets, and the composition of our income and assets, we do not believe we were a PFIC for U.S. federal income tax purposes for our taxable year ended December 31, 2012. However, the application of the PFIC rules is subject to uncertainty in several respects, and we cannot assure you that the U.S. Internal Revenue Service will not take a contrary position. A non-U.S. corporation is considered a PFIC for U.S. federal income tax purposes, for any taxable year if either:

·at least 75% of its gross income is passive income, or the “income test,” or

·at least 50% of the value of its assets (based on an average of the quarterly values of the assets during a taxable year) is attributable to assets that produce or are held for the production of passive income, or the “asset test.”

For this purpose, we will be treated as owning our proportionate share of the assets and earning our proportionate share of the income of any other corporation in which we own, directly or indirectly, 25% or more (by value) of the stock.

We must make a separate determination each year as to whether we are a PFIC. As a result, it is possible that our PFIC status will change in the current taxable year ending December 31, 2013, or a future taxable year. The relative percentage of our passive income compared to our active income has varied significantly year to year, including as a result of decreases in our gross profit from the sales of goods as a percentage of our gross income. For purposes of the income test, our gross income from the sales of goods is generally reduced by our cost of goods sold. Therefore, for example, if our cost of goods sold were to increase without an offsetting increase in our revenues from the sale of the related goods, or if our revenues decrease without an offsetting decrease in our cost of goods sold, we may become a PFIC under the income test. In addition, because the total value of our assets for purposes of the asset test generally will be calculated using the market price of our ADSs and ordinary shares, our PFIC status will depend in part on the market price of our ADSs and ordinary shares. Accordingly, it is possible that fluctuations in the market price of the ADSs and ordinary shares will result in our being a PFIC for any year. If we are a PFIC for any year during which you hold ADSs or ordinary shares, you generally will continue to be required to treat us as a PFIC for all succeeding years during which you hold such ADSs or ordinary shares. In addition, if we are a PFIC for any taxable year and any of our foreign subsidiaries is also a PFIC, a U.S. Holder would be treated as owning a proportionate amount (by value) of the shares of the subsidiary PFIC for purposes of the rules governing PFICs. You are urged to consult your tax advisors about the application of the PFIC rules to any of our subsidiaries.

If we are a PFIC for any taxable year during which you hold ADSs or ordinary shares, you will be subject to special tax rules with respect to any “excess distribution” that you receive and any gain you realize from a sale or other disposition (including a pledge) of the ADSs or ordinary shares, unless you make a “mark-to-market” election as discussed below. Distributions you receive in a taxable year that are greater than 125% of the average annual distributions you received during the shorter of the three preceding taxable years or your holding period for the ADSs or ordinary shares will be treated as an excess distribution. Under these special tax rules:

·the excess distribution or gain will be allocated ratably over your holding period for the ADSs or ordinary shares;

·the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which we were a PFIC, will be treated as ordinary income; and

·the amount allocated to each other year will be subject to the highest tax rate in effect for that year and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax attributable to each such year.

89

The tax liability for amounts allocated to years prior to the year of disposition or “excess distribution” cannot be offset by any net operating losses for such years, and gains (but not losses) realized on the sale of the ADSs or ordinary shares cannot be treated as capital, even if you hold the ADSs or ordinary shares as capital assets.

Alternatively, a U.S. Holder of “marketable stock” in a PFIC may make a mark-to-market election for stock of a PFIC to elect out of the tax treatment discussed in the two preceding paragraphs. If you make a mark-to-market election for the ADSs or ordinary shares, you will include in income each year an amount equal to the excess, if any, of the fair market value of the ADSs or ordinary shares as of the close of your taxable year over your adjusted basis in such ADSs or ordinary shares. You are allowed a deduction for the excess, if any, of the adjusted basis of the ADSs or ordinary shares over their fair market value as of the close of the taxable year. However, deductions are allowable only to the extent of any net mark-to-market gains on the ADSs or ordinary shares included in your income for prior taxable years. Amounts included in your income under a mark-to-market election, as well as gain on the actual sale or other disposition of the ADSs or ordinary shares, are treated as ordinary income. Ordinary loss treatment also applies to the deductible portion of any mark-to-market loss on the ADSs or ordinary shares, as well as to any loss realized on the actual sale or disposition of the ADSs or ordinary shares, to the extent that the amount of such loss does not exceed the net mark-to-market gains previously included for such ADSs or ordinary shares. Your basis in the ADSs or ordinary shares will be adjusted to reflect any such income or loss amounts. If you make a mark-to-market election, the tax rules that apply to distributions by corporations which are not PFICs would apply to distributions by us, except that the lower applicable capital gains rate discussed above under “Taxation of dividends and other distributions on the ADSs or ordinary shares” would not apply.

The mark-to-market election is available only for stock which is regularly traded on a qualified exchange or other market, as defined in applicable U.S. Treasury Regulations. We expect that the ADSs will continue to be listed on New York Stock Exchange and, consequently, if you are a holder of ADSs and the ADSs are regularly traded on the New York Stock Exchange, the mark-to-market election would be available to you were we to be or become a PFIC.

In general, if a non-U.S. corporation is a PFIC, a holder of shares in that corporation may avoid taxation under the rules described above by making a “qualified electing fund” election to include its share of the corporation’s income on a current basis, or a “deemed sale” election once the corporation no longer qualifies as a PFIC. However, you may make a qualified electing fund election with respect to your ADSs or ordinary shares only if we agree to furnish you annually with required tax information, and we do not presently intend to prepare or provide such information.

If you hold ADSs or ordinary shares in any year in which we are a PFIC, you will be required to file an annual information report with the U.S. Internal Revenue Service regarding distributions received on the ADSs or ordinary shares and any gain realized on the disposition of the ADSs or ordinary shares.

You are urged to consult your tax advisor regarding the application of the PFIC rules to your investment in ADSs or ordinary shares.

Information reporting and backup withholding

Dividend payments with respect to ADSs or ordinary shares and proceeds from the sale, exchange or redemption of ADSs or ordinary shares that are made within the United States or through certain U.S. related financial intermediaries generally are subject to information reporting to the Internal Revenue Service and may be subject to U.S. backup withholding. Backup withholding will not apply, however, to a U.S. Holder who furnishes a correct taxpayer identification number and makes any other required certification or who is otherwise exempt from backup withholding. U.S. Holders who are required to establish their exempt status can provide such certification on Internal Revenue Service Form W-9. U.S. Holders should consult their tax advisors regarding the application of the U.S. information reporting and backup withholding rules.

Backup withholding is not an additional tax. Amounts withheld as backup withholding can be credited against your U.S. federal income tax liability, and you can obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the Internal Revenue Service and furnishing any required information.

Additional reporting requirements

Certain U.S. Holders who are individuals may be required to report information relating to an interest in our ADSs or ordinary shares, subject to certain exceptions (including an exception for ADSs or ordinary shares held in accounts maintained by certain financial institutions). U.S. Holders should consult their tax advisers regarding the effect, if any, of this legislation on their ownership and disposition of the ADSs and ordinary shares.

H.Documents on Display

We are subject to the periodic reporting and other informational requirements of the Securities Exchange Act of 1934. Under the Securities Exchange Act of 1934, we are required to file reports and other information with the SEC. Copies of reports and other information, when so filed, may be inspected without charge and may be obtained at prescribed rates at the public reference facilities maintained by the SEC. The SEC also maintains a web site at www.sec.gov that contains reports, proxy and information statements, and other information regarding registrants that make electronic filings with the SEC using its EDGAR system. As a foreign private issuer, we are exempt from the rules under the Securities Exchange Act of 1934 prescribing the furnishing and content of quarterly reports and proxy statements, and officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Securities Exchange Act of 1934.

We will furnish JPMorgan Chase Bank, N.A., the depositary of our ADSs, with our annual reports, which will include a review of operations and annual audited consolidated financial statements prepared in conformity with U.S. GAAP, and all notices of shareholders’ meetings and other reports and communications that are made generally available to our shareholders. The depositary will make such notices, reports and communications available to holders of ADSs and, upon our request, will mail to all record holders of ADSs the information contained in any notice of a shareholders’ meeting received by the depositary from us.

Our financial statements have been prepared in accordance with U.S. GAAP.

I.Subsidiary Information

For a listing of our subsidiaries, see “Item 4. Information on the Company—C. Organizational Structure.”

Item 11.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the potential loss arising from adverse changes in market rates and prices, such as interest rates, foreign currency exchange rates and commodity prices.

Inflation

According to the National Bureau of Statistics of China, China’s overall national inflation rate, as represented by the general consumer price index, was approximately 3.2% in 2010, 5.4% in 2011 and 2.6% in 2012. Inflation in China has not materially impacted our results of operations in recent years, but we can provide no assurance that we will not be affected in the future.

Interest rate risk

Our exposure to interest rate risk primarily relates to the interest rates for our outstanding debt and the interest income generated by excess cash invested in liquid investments with original maturities of three months or less. As of December 31, 2012, we had short-term and long-term bank loans in the amount of $787.0 million and $15.9 million, respectively. Our short-term bank loans and long-term borrowings are subject to floating interest rates. As of December 31, 2012, our total borrowings amounted to $802.9 million with interest rates varying from 3.0% to 12.0% for the year ended December 31, 2012. Assuming the principal amount of the outstanding bank borrowings remains approximately the same as of December 31, 2012, a 1% increase in each applicable interest rate would add approximately $8.0 million to our interest expenses for the year ended December 31, 2012. We have not used any derivative financial instruments to manage our interest risk exposure. Interest-earning instruments carry a degree of interest rate risk. We have not been exposed to material risks due to changes in interest rates. However, our future interest income may be lower than expected due to changes in market interest rates.

91

Foreign currency risk

Our financial statements are expressed in U.S. dollars. The functional currency of WSP Holdings is U.S. dollar and the functional currency of our PRC subsidiaries is Renminbi. Our overseas sales are denominated in U.S. dollars, whereas our domestic sales are denominated in Renminbi. A substantial portion of our costs and expenses, however, is denominated in Renminbi. Consequently, fluctuations in exchange rates, particularly among the U.S. dollar and Renminbi, could affect our gross and net margins and result in foreign exchange and operating losses. To the extent we hold assets denominated in U.S. dollars, including the net proceeds to us from the initial public offering, any appreciation of the Renminbi against the U.S. dollar could result in a change to our statement of operations and a reduction in the value of our U.S. dollar denominated assets. On the other hand, a decline in the value of Renminbi against the U.S. dollar could reduce the U.S. dollar equivalent amounts of our financial results, the value of your investment in our company and the dividends we may pay in the future, if any, all of which may have a material adverse effect on the prices of our ADSs.

On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of the Renminbi to the U.S. dollar. Under the new policy, the Renminbi was permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. This change in policy caused the Renminbi to appreciate approximately 21.5% against the U.S. dollar over the following three years. From July 2008 until June 2010, however, the Renminbi traded stably within a narrow range against the U.S. dollar. On June 20, 2010, the People’s Bank of China announced that the PRC government would reform the Renminbi exchange rate regime and increase the flexibility of the exchange rate. Between June 20, 2010 and December 31, 2012, the Renminbi appreciated by approximately 9.1% against the U.S. dollar.  It is difficult to predict how long the current situation may last and when and how it may change again.

Because a substantial portion of our costs and expenses is denominated in Renminbi, a resumption of the appreciation of the Renminbi against the U.S. dollar would further increase our costs in U.S. dollar terms. In addition, as we rely entirely on dividends paid to us by our operating subsidiaries in China, any significant depreciation of the Renminbi against the U.S. dollar may have a material adverse effect on our revenues and financial condition, and the value of, and any dividends payable on, our ordinary shares. For example, to the extent that we need to convert U.S. dollars into Renminbi for our operations, appreciation of the Renminbi against the U.S. dollar would have an adverse effect on the Renminbi amount we receive from the conversion. Conversely, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our common shares or for other business purposes, appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amount available to us. The Renminbi appreciated by approximately 1.0% against the U.S. dollar in 2012. Based on the amount of our U.S. dollar-denominated financial assets as of December 31, 2012, a 10% decrease in the exchange rate of the U.S. dollar against the Renminbi would have resulted in a decrease of approximately $12.3 million in the value of our U.S. dollar-denominated financial assets at December 31, 2012.

We have been monitoring and managing our foreign exchange exposure as an integral part of our overall risk management program. We maintain a foreign currency risk management strategy that uses forward contracts to limit the effects of foreign exchange rate fluctuations on financial results, when necessary. For instance, in July 2008, we entered into a series of monthly forward foreign exchange contracts with Standard Chartered Bank (China) Limited, pursuant to which Standard Chartered Bank agreed to purchase from WSP China a total of $120.0 million in U.S. dollar in exchange for certain amount of RMB at a fixed exchange rate. We settled these contracts in 2009 and have not entered into any new contracts. In accordance with ASC 815-10, “Derivatives and Hedging”, we apply the marked-to-market rules and recognize gains or losses resulted from changes in the fair value of the forward contracts in the consolidated statements of operations. See also “Item 3. Key Information—D. Risk Factors—Risks related to doing business in China—Fluctuations in exchange rates could adversely affect our business as well as result in foreign currency exchange losses.”

Commodity price risk

We are exposed to market risk of price fluctuations related to the purchase of raw materials, especially round steel billets. We purchase round steel billets directly from suppliers in PRC. In order to secure a steady supply of round steel billets, in December 2006, we entered into a five-year cooperation agreement with Wuxi Xuefeng, under which Wuxi Xuefeng was committed to supply us with 300,000 to 600,000 tonnes of round steel billets per year. The purchase price was subject to the parties’ periodic negotiations. This agreement expired in 2011 and going forward, we expect to fulfill our requirements for round steel billets through individual purchase orders from Wuxi Xuefeng on an as needed basis. We also purchase round steel billets from other PRC suppliers at market prices. We do not use any commodity derivatives to manage our commodity price risks.

The depositary may sell (by public or private sale) sufficient securities and property received in respect of a share distribution, rights and/or other distribution prior to such deposit to pay such charge.

The following additional charges shall be incurred by the ADR holders, by any party depositing or withdrawing shares or by any party surrendering ADSs or to whom ADSs are issued (including, without limitation, issuance pursuant to a stock dividend or stock split declared by us or an exchange of stock regarding the ADRs or the deposited securities or a distribution of ADSs), whichever is applicable:

Fees payable to and from the depositary

Prior to 2012, our depositary reimbursed us certain expenses we incurred that were related to establishment and maintenance of the ADR program, including investor relations expenses and exchange application and listing fees. The depositary deducted the reimbursed expenses from the amount of fees payable to us, which we record as other income. We received from the depositary reimbursement of $692,000, nil and nil for the years ended December 31, 2010, 2011 and 2012, respectively, for certain reasonable expenses related to our ADS program.

In 2012, we paid $200,000 million in service fees to our depositary.

Item 15.CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures

Under the supervision and with the participation of our management, including our chief executive officer and our chief financial officer, we carried out an evaluation of the effectiveness of our disclosure controls and procedures, which is defined in Rules 13a-15(e) of the Exchange Act, as of the period covered by this annual report. Based on that evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were not effective as of the end of the period covered by this annual report.

Management’s annual report on internal control over financial reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such item is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, for our company. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements in accordance with U.S. GAAP and includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of a company’s assets, (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that a company’s receipts and expenditures are being made only in accordance with authorizations of a company’s management and directors, and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of a company’s assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial statements would be prevented or detected. Also, projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

94

Our management has conducted an assessment, including testing of the design and the effectiveness of our internal control over financial reporting as of December 31, 2012. In making its assessment, management used the criteria in “Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.” Based on this evaluation, our chief executive officer and chief financial officer concluded that our internal control over financial reporting was not effective due to three material weaknesses, as defined by Auditing Standard 5, “An Audit of Internal Control Over Financial Reporting That Is Integrated with An Audit of Financial Statements.” See “Item 15. Control and Procedures.” The material weaknesses identified were:

·inadequate procedures for approving related party transactions, including lack of information provided to the audit committee for approval before the transactions occurred and certain related party transactions were reported to the board of directors only after they had occurred;

·due to the need to obtain bank financing, bill financing transactions and increased bills payable in intragroup transactions without physical delivery of the underlying goods occurred without following proper approval and other procedures and, such transactions may not be in compliance with relevant PRC laws and regulations;

·inadequate logistical controls and procedures to ensure accurate shipment of goods; and

·insufficient skilled resources available for the purposes of financial reporting and internal audit.

We have designed certain control measures for implementation to address certain of these material weaknesses and will continue to monitor the status of implementation to ensure that these control procedures are operating effectively. We are in the process of implementing measures to address these material weaknesses. For example, we have provided supplemental information about the related party transactions to the audit committee and are in the process of ensuring future related party transactions will be timely and accurately reported. We have arranged for the shipment of these products back to Thailand. We will also strengthen our resources by recruiting more accounting personnel with sufficient experience and qualification and by enhancing training provided to our staff for the purposes of financial reporting and internal audit.

Changes in internal controls over financial reporting

There were no adverse changes in our internal controls over financial reporting that occurred during the year ended December 31, 2012 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Item 16A.AUDIT COMMITTEE FINANCIAL EXPERT

Mr. Dennis D. Zhu qualifies as an “audit committee financial expert” as defined in Item 16A of Form 20-F. Messrs. Weidong Wang, Dennis D. Zhu and Michael Muhan Liu satisfy the “independence” requirements of Section 303A of the Corporate Governance Rules of the New York Stock Exchange and Rule 10A-3 under the Securities Exchange Act of 1934.

Item 16B.CODE OF ETHICS

Our board of directors has adopted a code of ethics that applies to our directors, officers, employees and agents, including certain provisions that specifically apply to our chief executive officer, chief financial officer, chief operating officer, chief technology officer, vice presidents and any other persons who perform similar functions for us.

Item 16C.PRINCIPAL ACCOUNTANT FEES AND SERVICES

WSP HOLDINGS LIMITED

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

WSP Holdings Limited

We have audited the accompanying consolidated balance sheets of WSP Holdings Limited and its subsidiaries (collectively, the “Company”) as of December 31, 2011 and 2012 and the related consolidated statements of operations, comprehensive income, changes in stockholders’ equity, and cash flows for the years then ended. We have also audited the condensed parent company financial statements for the years ended December 31, 2011 and 2012 included in Schedule I. These consolidated financial statements and condensed parent company financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and the condensed parent company financial statements based on our audit.

We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatements. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall consolidated financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2011 and 2012, and the results of their operations and their cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the related parent company financial statements included in Schedule I, when considered in relation to the consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2(a) to the consolidated financial statements, the fact that the Company suffered significant operating loss and had working capital deficiency while a significant amount of short-term borrowings is required to be refinanced raises substantial doubt about the Company’s ability to continue as a going concern. Management’s plans and actions in regard to these matters are further described in Note 2(a). The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

We also have audited the adjustments to the financial statements and parent company financial statements included in Schedule I for the years ended December 31, 2010 and 2011, respectively, to retrospectively apply the change in accounting for the presentation of comprehensive income, as described in Note 2(cc) to the consolidated financial statements. In our opinion, such adjustments are appropriate and have been properly applied. We were not engaged to audit, review, or apply any procedures to the financial statements and parent company financial statements included in Schedule I of the Company for the year ended December 31, 2010, other than those adjustments, and, accordingly, we do not express an opinion or any other form of assurance on the 2010 financial statements or financial statement schedule taken as a whole.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF WSP HOLDINGS LIMITED

We have audited, before the effects of the adjustments to retrospectively apply the change in the presentation of comprehensive income described in Note 2(cc), the accompanying consolidated statements of operations, changes in equity and cash flows of WSP Holdings Limited and its subsidiaries (the “Company”) for the year ended December 31, 2010 and the related financial statement schedule included in Schedule I. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on the financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements, before the effects of the adjustments to retrospectively apply the change in the presentation of comprehensive income described in Note 2(cc), present fairly, in all material respects, the results of the Company’s operations and the Company’s cash flows for the year ended December 31, 2010 in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to such consolidated financial statements taken as a whole, presents fairly in all material respects, the information set forth therein.

We were not engaged to audit, review, or apply any procedures to the adjustments to retrospectively apply the change in the presentation of comprehensive income described in Note 2(cc) and, accordingly, we do not express an opinion or any other form of assurance about whether such adjustments are appropriate and have been properly applied. Those adjustments were audited by MaloneBailey, LLP.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern.  The fact that the Company suffered significant operating loss and had working capital deficiency and negative operating cash flow while a significant amount of short-term borrowings is required to be refinanced raises substantial doubt about the Company’s ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

1.ORGANIZATION AND DESCRIPTION OF BUSINESS

WSP Holdings Limited (“WSP Holdings”) was incorporated in the Cayman Islands on November 16, 2006. WSP Holdings together with its subsidiaries (collectively the “Company”), is a Chinese manufacturer of seamless casing, tubing and drill pipes used for oil and natural gas exploration, drilling and extraction.

The Company holds its interest in the operating subsidiaries indirectly through a wholly owned intermediate holding company, First Space Holdings Limited (“FSHL”) that was incorporated in the British Virgin Islands (“BVI”).

A majority of the Company’s business is conducted through a wholly owned operating subsidiary established in the People’s Republic of China (“PRC”), Wuxi Seamless Oil Pipes Company Limited (“WSP China”).

As of December 31, 2012, the Company’s subsidiaries are as follows:

Name	Date ofincorporation/acquisition	Place ofincorporation	Equityinterestholder	Percentageof legalownership

WSP China was established in the PRC on November 17, 1999. Through a series of recapitalization and reorganization, WSP China was ultimately owned by WSP Holdings, which in turn owned by Expert Master Holdings Limited, an entity controlled by Mr. Longhua Piao, (“Mr. Piao”), a PRC citizen and UMW China Ventures (L) Ltd., an entity controlled by UMW Holdings Berhad (“UMW”), a company incorporated in Malaysia.

In December 2007, the Company completed an initial public offering of American depositary shares (“ADSs”) in the New York Stock Exchange in the United States of America.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(a)Basis of presentation, principles of consolidation and going concern

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

All intercompany accounts and transactions have been eliminated. The results of subsidiaries acquired or disposed of during the respective periods are included in the consolidated statements of operations from the effective date of acquisition or up to the effective date of disposal, as appropriate. The portion of the income or loss applicable to non-controlling interests in subsidiary undertakings is reflected in the consolidated statements of operations.

Since 2009 the Company experienced a significant decline in sales to the United States of America due to anti-dumping and countervailing duty on seamless pipes made in China, imposed by the United States government as set out in Note 28(c). In 2012, products sold to the United States of America accounted for 9.3% of the Company’s net revenues, compared to 9.7% and 6.3% of the Company’s net revenues, in 2010 and 2011, respectively. The Company suffered significant operating losses and had working capital deficiencies for the year ended December 31, 2012. In addition, the Company has a significant amount of short term borrowings, totaling $786,987, which requires the Company to secure additional funds given the Company’s current cash position. The Company’s available liquidity includes cash and cash equivalents, restricted cash, term deposit, and unused credit facilities. As of December 31, 2012, the Company had cash and cash equivalents balance of $26,105, restricted cash of $206,802, term deposit of $318 and unused bank credit facilities of $36,113 which are subject to renewal within the next twelve months.

Future uses of cash will include, among other possible demands:

· Continuing capital expenditures;

· Repayment of bank borrowings; and

· Continuing use of cash in operations

The Company has taken various actions to conserve cash, procure additional financing and improve the liquidity. Such actions include reducing working capital requirements in operations through reduction of accounts receivables, inventories and other measures and reducing capital spending through delaying or scaling down certain projects. The Company’s ability in meeting future cash flow requirements is dependent on many events outside of its direct control, including, among other things, successful renewal of bank borrowings, additional financing from the banks and capital market, and recovery of demand and selling prices for Oil Country Tubular Goods (“OCTG”) products.

According to the repayment schedules specified in the loan agreements, which do not include $210,920 of borrowings due after one year that was reclassified as current liability due to breach of financial covenants, $501,657 of the borrowings became due for repayment during the first nine months of 2013. The Company was able to renew $70,235 and repay $431,422 of those borrowings and obtained new bank borrowings of $470,894. While the Company is required to repay approximately $256,894 bank borrowings as of the date of this report through December 31, 2013, the Company believes it will be able to renew a substantial portion of its bank borrowings and bank credit facilities as they fall due. However, there is no guarantee that such renewal will occur. In August 2011, the Company entered into a syndicated bank credit facility agreement with two lead banks and six other participating commercial banks which agreed to grant the Company a total of $455,016 (RMB 2,860,000) of the syndicated bank credit facility in replacement of certain existing loan facilities from the relevant banks. As of December 31, 2012, the Company had drawn down $424,436 out of the total approved loan facility. Under the syndicated bank credit facility agreement and other bank agreements, the Company is required to comply with certain financial covenants, including but not limited to, maintaining certain required financial ratios and asset pledge. The Company is currently in violation of the covenants. See more discussion in Note 17.

In order to counteract the adverse impact of anti-dumping and countervailing duty imposed by the United States of America, the Company is actively pursuing new opportunities in other international markets. Since the end of 2011 and in 2012, the Company secured several new order wins in international markets such as Venezuela, Ecuador and Oman.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization of assets and the liquidation of liabilities in the ordinary course of business.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES — continued

(b)Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenue and expenses in the financial statements and accompanying notes. Significant accounting estimates reflected in the Company’s consolidated financial statements include allowance for doubtful accounts, the useful lives and impairment for property, plant and equipment, goodwill and acquired intangible assets, write-down in value of inventory, provision for product warranty, provision for income tax and share-based payments. Actual results could differ from those estimates.

(c)Cash and cash equivalents

Cash and cash equivalents consist of cash on hand and highly liquid short-term deposits which are unrestricted as to withdrawal and use, and which have maturities of three months or less when purchased.

(d)Accounts receivable and allowance for doubtful accounts

Accounts receivable are recorded at the invoiced amount and do not bear interest. Amounts collected on accounts receivable are included in the net cash from operating activities in the consolidated statements of cash flows. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. Management considers the following factors when determining the collectability of specific customer accounts: customer credit-worthiness, past transaction history with the customer, and current economic industry trends.

(e)Inventories

Inventories are stated at the lower of cost or market value. Cost is determined by the weighted average method. Write-downs of potentially obsolete or slow-moving inventories are recorded based on the management’s specific analysis of future sales forecasts and economic conditions.

(f)Property, plant and equipment

Property, plant and equipment are recorded at cost less accumulated depreciation except for land in the United States of America and Thailand which is stated at cost and is not amortized. Assets under construction are not depreciated until construction is completed and the assets are ready for their intended use. Gains and losses from the disposal of property, plant and equipment are included in income from operations. Depreciation is provided on a straight-line basis over the estimated useful lives of the assets. Estimated useful lives of property, plant and equipment are as follows:

Buildings	20-30 years
Equipment, furniture and fixtures	5 years
Plant and machinery	10 years
Motor vehicles	5 years
Computer equipment and software	3-5 years

(g)Prepaid lease payments for land use rights

All land in the PRC is owned by the PRC government. The government in the PRC, according to the relevant PRC law, may sell the right to use the land for a specified period of time. Payments for acquiring land use rights represent prepayments of rentals over the periods the rights are granted and are stated at the amount prepaid less accumulated amortization and any recognized impairment loss. Amortization is provided over the term of the land use right agreement on a straight-line basis. Prepaid lease payments which are to be amortized in the next twelve months or less are classified as current assets.

(h)Intangible assets

Intangible assets are initially measured based on their cost less accumulated amortization. Amortization is calculated on a straight-line basis over their expected useful economic lives.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES — continued

(i)Impairment of long-lived assets

The Company reviews its long lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may no longer be recoverable. When these events occur, the Company measures impairment by comparing the carrying value of the long-lived assets to the estimated undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, the Company would recognize an impairment loss based on the fair value of the assets.

(j)Goodwill

The excess of the purchase price over the fair value of net assets acquired is recorded on the consolidated balance sheet as goodwill. Goodwill is not amortized but is tested for impairment annually or more frequently if events or changes in circumstances indicate that it might be impaired. The Company performs its annual goodwill impairment test on December 31 of each year for all reporting units. Goodwill is tested following a two-step process. The first step compares the fair value of each reporting unit to its carrying amount, including goodwill. If the fair value of each reporting unit exceeds its carrying amount, goodwill is not considered to be impaired and the second step will not be required. If the carrying amount of a reporting unit exceeds its fair value, the second step compares the implied fair value of goodwill to the carrying value of a reporting unit’s goodwill. The implied fair value of goodwill is determined in a manner similar to accounting for a business combination with the allocation of the assessed fair value determined in the first step to the assets and liabilities of the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned to the assets and liabilities is the implied fair value of goodwill. An impairment loss is recognized for any excess in the carrying value of goodwill over the implied fair value of goodwill. The Company’s goodwill resulted from acquisition of Chaoyang Seamless, which is identified by management as held for sale as of December 31, 2011. The Company no longer holds any goodwill after disposal of Chaoyang Seamless, see Note 5.

(k)Equity-method investment

An affiliated company over which the Company has the ability to exercise significant influence, but does not have a controlling interest is accounted for using the equity method. Significant influence is generally considered to exist when the Company has an ownership interest in the voting stock of the investee of between 20% and 50%, and other factors, such as representation on the investee’s Board of Directors, voting rights and the impact of commercial arrangements, are considered in determining whether the equity method of accounting is appropriate. The Company’s share of earnings of equity affiliate is included in the accompanying consolidated statements of operations below provision for income taxes.

The Company reviews the investment for other-than temporary impairment whenever events or changes in circumstances indicate that the carrying value may no longer be recoverable based on the specific identification method. The Company considers available quantitative and qualitative evidence in evaluating potential impairment and recognize the impairment loss if the carrying value exceeds fair value.

(l)Interest capitalization

Interest expenses incurred in relation to construction in progress are capitalized only during periods in which activities necessary to prepare the property, plant and equipment for its intended use are in progress. Capitalized interest expenses are recorded in construction in progress, and reclassified to property, plant and equipment upon substantial completion. Interest expenses incurred for such items after the construction is substantially completed and ready for the intended use are charged to expense as incurred.

(m)Revenue recognition

The Company’s principal sources of revenues are the sales of specialized oil pipes and to a lesser extent, sales of iron ore. The Company recognizes revenue when (1) there is persuasive evidence of an arrangement with the customer, (2) product is shipped and title has passed, and the Company has no significant future performance obligation, (3) the amount due from the customer is fixed or determinable, and (4) collectability is reasonably assured. There is no significant customer acceptance process. The Company assesses whether the amount due from the customer is fixed or determinable based on the terms of the agreement with the customer, including, but are not limited to, the payment terms associated with the transaction. The Company assesses collection based on a number of factors, including past transaction history with the customer and creditworthiness of the customer.

Sales of iron ore is recognized on the same criteria above except (2) that revenue is recognized when the iron ore is collected by the customer at the destination port.

The Company presents revenue net of value added tax (“VAT”), applicable local government levies and sales returns. VAT on sales is calculated at 17% on revenue from product sales and paid after deducting input VAT on purchases. Net VAT balance between input VAT and output VAT is reflected in the accrued expenses and other current liabilities or prepaid expenses and other current assets. For products sold to overseas customers by the PRC entities, the Company first pays VAT at 17% and then receives a refund of 13%. The Company records VAT refund receivables on an accrual basis. VAT refund is recorded as a deduction to VAT payable on the consolidated balance sheets.

(n)Shipping and handling costs

Shipping and handling costs of products sold are included in cost of revenues and amounted to $33,796 and $40,954 and $32,512, for the years ended December 31, 2010, 2011 and 2012, respectively.

(o)Government grants

Government grants include cash subsidies as well as other subsidies received from the PRC government by the subsidiaries of the Company. Such subsidies are generally provided as incentives from the local government to encourage the expansion of local business. Government grants are recognized when received and all the conditions specified in the grant have been met. Government grant recognized as other operating income were $2,015, $343 and $3,255 for each of the years ended December 31, 2010, 2011 and 2012, respectively. Capital grants received in advance of the acquisition of equipment are recorded initially in other current liabilities and then offset against the cost of the related equipment upon acquisition.

(p)Research and development costs

Research and development costs are incurred in the development of the new products and processes, including significant improvements and refinements to existing products. All research and development costs are expensed as incurred. The Company incurred research and development expenses of $1,743, $1,536 and $1,452 for the years ended December 31, 2010, 2011 and 2012, respectively.

(q)Product warranty

The Company provides a warranty to customers that its products will meet the stated functionality as agreed to in each sales arrangement. The Company provides for the estimated warranty costs under these guarantees based upon historical experience and management’s estimate of the level of future claims.

(r)Retirement and other post-retirement benefits

Contributions to retirement schemes, which are defined contribution plans, are charged to expense as and when the related employee service is provided.

(s)Operating leases

Leases where substantially all the rewards and risks of ownership of assets remain with the leasing company are accounted for as operating leases. Payments made under operating leases are charged to the consolidated statements of operations on a straight-line basis over the lease period.

(t)Income taxes

Deferred income taxes are recognized for temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements, net operating loss carry forwards and credits, by applying enacted statutory tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws and regulations applicable to the Company as enacted by the relevant tax authorities.

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement.

(u)Foreign currency translation

The Company has chosen United States dollar (“$”) as its reporting currency. The functional currency of WSP Holdings, FSHL and Houston OCTG is United States dollar, while the functional currency of the Company’s major operating subsidiaries in the PRC is Renminbi and the functional currency of the Company’s operating subsidiary in Thailand is Baht. Monetary assets and liabilities denominated in other currencies are translated into the applicable functional currencies at the rates of exchange in effect at the balance sheet date. Nonmonetary assets and liabilities denominated in other currencies are remeasured into the applicable functional currencies at historical exchange rates and transactions denominated in other currencies are converted at the applicable rates of exchange prevailing when the transactions occurred. Exchange gains and losses are recognized in the consolidated statements of operations.

The group entities with functional currency other than United States dollar translate their financial position and operating results into United States dollar. Balance sheet accounts are translated using the exchange rates in effect at the balance sheet date. Transactions in currencies other than the United States dollar are translated using the average exchange rate prevailing in the period when transactions occurred. Translation adjustments are reported as cumulative translation adjustments and are shown as a separate component of other comprehensive income in the accompanying consolidated statements of changes in equity and comprehensive income.

(v)Foreign currency risk

The Renminbi is not a freely convertible currency. The State Administration for Foreign Exchange, under the authority of the People’s Bank of China, controls the conversion of Renminbi into other currencies. The value of the Renminbi is subject to changes in central government policies and to international economic and political developments affecting supply and demand in the China Foreign Exchange Trading System market. The cash and cash equivalents of the Company included aggregate amounts of $34,471, $22,424 and $19,410 as of December 31, 2010, 2011 and 2012, respectively, which were denominated in Renminbi.

In addition to Renminbi, the Company may from time to time review its working capital requirements and hold the excess capital in other foreign currencies. The Company had total amount of cash and cash equivalents of $1,374, $116 and $431 as of December 31, 2010, 2011 and 2012, respectively, which are held in currency other than functional currency of the respective entities.

(w)Concentration of credit risks

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash and accounts and bills receivable. The Company places its cash and cash equivalents and restricted cash with financial institutions. The Company does not require collateral or other security to support financial instruments subject to credit risks. The Company establishes an allowance for doubtful accounts primarily based upon the age of receivables and factors surrounding the credit risk of specific customers.

Net revenues from customers accounting for 10% or more of total net revenues are as follows:

	Year ended
Customer	December 31,2010	December 31,2011	December 31,2012
	%	%	%
A	20	34	40
B	11	22	—

(x)Fair value

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.

Authoritative literature provides a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement as follows:

Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

(y)Financial instruments

Financial instruments include cash and cash equivalents, restricted cash, term deposits, accounts and bills receivable, amounts due from related parties, advances to suppliers, equity-method investments, accounts payable, advances from customers and other payables, amounts due to related parties, borrowings and foreign currency forward contracts. The carrying amounts of cash and cash equivalents, restricted cash, term deposits, accounts and bills receivable, advances to suppliers, amounts due from related parties, advances from customers, accounts payable, other payables and amounts due to related parties approximate their fair value due to the short term maturities of these instruments.

Equity-method investments have no quoted market prices and it is not practicable to estimate their fair value without incurring excessive costs. The Company reviews the investments for impairment whenever events or changes in circumstances indicate that the carrying amount may no longer be recoverable. The Company would recognize an impairment loss if it is determined that the impairment is other than temporary.

Bank borrowings bear a floating rate of interest. Because the stated interest rate reflects the market rate, the carrying value of the bank borrowings approximates its fair value.

Foreign currency forward contracts are marked to market based on the prevailing forward exchange rate quoted by the contracted bank with changes in the fair value recognized in the consolidated statements of operations. The Company does not designate the foreign currency forward contracts as hedging instruments. Assets and liabilities resulted from foreign currency forward contracts are recorded at its fair value (level 1 inputs).

(z)Stock-based compensation

Stock-based compensation expense is recognized based on grant-date fair value estimated in accordance with an authoritative pronouncement. The Company recognizes the compensation costs net of a forfeiture rate on a straight-line basis over the requisite service period of the award with a corresponding impact reflected in additional paid-in capital. The estimate of forfeitures will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of change and will also impact the amount of stock compensation expense to be recognized in future periods.

(aa)Net income (loss) per share

Basic net income (loss) per ordinary share is computed by dividing net income (loss) attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period.

Diluted net income (loss) per ordinary share reflects the potential dilution that could occur if securities or other contracts to issue ordinary shares were exercised or converted into ordinary shares.

(bb)Assets held for sale

For the business where management has committed to a plan to divest, which is typically demonstrated by approval from the Board of Directors, the business is valued at the lower of its carrying amount or estimated fair value less cost to sell. If the carrying amount of the business exceeds its estimated fair value, an impairment loss is recognized. Upon designation as an asset held for sale, we cease depreciation.

(cc)Recently adopted accounting pronouncement

In June 2011, the FASB issued an update to ASC 220, Comprehensive Income. This ASU requires entities to present components of comprehensive income in either a continuous statement of comprehensive income or two separate but consecutive statements that would include reclassification adjustments by component for items that are reclassified from other comprehensive income to net income on the face of the financial statements. In December 2011, the FASB issued an update to this ASU indefinitely deferring the implementation of the reclassification adjustments by component requirement of the ASU issued in June 2011. The Company adopted this pronouncement effective January 1, 2012 and the adoption did not have any significant impact on the Company’s financial condition or results of operations.

In September 2011, the FASB issued an update to ASC 350, Intangibles—Goodwill and Other. This ASU amends the guidance in ASC 350-20 on testing for goodwill impairment. The revised guidance allows entities testing for goodwill impairment to have the option of performing a qualitative assessment before calculating the fair value of the reporting unit. The ASU does not change how goodwill is calculated or assigned to reporting units, nor does it revise the requirement to test annually for impairment. The ASU is limited to goodwill and does not amend the annual requirement for testing other indefinite-lived intangible assets for impairment. The Company adopted this pronouncement effective January 1, 2012 and the adoption did not have any significant impact on the Company’s financial condition or results of operations.

(dd)Recently issued accounting pronouncements not yet adopted

In December 2011, the FASB issued changes to the disclosure of offsetting assets and liabilities. These changes require an entity to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The enhanced disclosures will enable users of an entity’s financial statements to understand and evaluate the effect or potential effect of master netting arrangements on an entity’s financial position, including the effect or potential effect of rights of setoff associated with certain financial instruments and derivative instruments. The ASU is effective for annual reporting periods beginning on or after January 1, 2013. The Company does not expect the adoption to have a significant impact on its consolidated financial statements.

In July 2012, the FASB issued revised guidance on “Testing Indefinite-Lived Intangible Assets for Impairment.” The revised guidance applies to all entities, both public and nonpublic, that have indefinite-lived intangible assets, other than goodwill, reported in their financial statements. Under the revised guidance, an entity has the option first to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform a quantitative impairment test by comparing the fair value with the carrying amount in accordance with Subtopic 350-30. An entity also has the option to bypass a qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment test. An entity will be able to resume performing the qualitative assessment in any subsequent period. In conducting a qualitative assessment, an entity should consider the extent to which relevant events and circumstances, both individually and in the aggregate, could have affected the significant inputs used to determine the fair value of the indefinite-lived intangible asset since the last assessment. An entity also should consider whether there have been changes to the carrying amount of the indefinite-lived intangible asset when evaluating whether it is more likely than not that the indefinite-lived intangible asset is impaired. An entity should consider positive and mitigating events and circumstances that could affect its determination of whether it is more likely than not that the indefinite-lived intangible asset is impaired. The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The Company does not expect the adoption to have a significant impact on its consolidated financial statements.

In February 2013, the FASB issued ASU 2013-02, “Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income” (“ASU 2013-02”). Under ASU 2013-02, an entity is required to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. ASU 2013-02 does not change the current requirements for reporting net income or other comprehensive income in the financial statements. The amendments in this update will be effective for fiscal periods beginning after December 15, 2012. The Company does not expect the adoption to have a significant impact on its consolidated financial statements.

In March 2013, the FASB issued ASU 2013-05, “Foreign Currency Matters (Topic 830)—Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity”. These amendments provide guidance on releasing Cumulative Translation Adjustments when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. In addition, these amendments provide guidance on the release of CTA in partial sales of equity method investments and in step acquisitions. For public entities, the amendments are effective on a prospective basis for fiscal years and interim reporting periods within those years, beginning after December 15, 2013. The amendments should be applied prospectively to derecognition events occurring after the effective date. Prior periods should not be adjusted. The Company does not expect the adoption to have a significant impact on its consolidated financial statements.

(dd)Recently issued accounting pronouncements not yet adopted

In July 2013, the FASB issued ASU 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists”. These amendments provide that an unrecognized tax benefit, or a portion thereof, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except to the extent that a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date to settle any additional income taxes that would result from disallowance of a tax position, or the tax law does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, then the unrecognized tax benefit should be presented as a liability. For public entities, the amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Company is currently in the process of evaluating the impact of the adoption on its consolidated financial statements.

3.DISPOSAL OF KUITUN SEAMLESS SPECIAL STEEL CO., LTD. (“KUITUN SEAMLESS”)

On July 18, 2011, the Company’s wholly-owned subsidiary, Bazhou Seamless, entered into an agreement with Shandong Shiheng Special Steel Co., Ltd. to dispose of its entire equity interests in Kuitun Seamless for a net cash consideration of $9,831 and at the same time, to retain certain assets, mainly office equipment, furniture and fixtures of Kuitun Seamless following the disposal. The gain on disposal of Kuitun Seamless was $3,268, which was reported as “Gain on disposal of subsidiary” included in other operating income for the year ended December 31, 2011.

The Company determined that disposal of Kuitun Seamless did not constitute a discontinued operation, as the operation capacity of Kuitun Seamless was absorbed by other subsidiaries of the Company.

4.DISPOSAL OF JIANGSU FANLI PIPE CO., LTD. (“JIANGSU FANLI”)

On February 28, 2010, the Company’s wholly-owned subsidiary, WSP China, together with three non-controlling investors of Jiangsu Fanli entered into an agreement with Zhejiang Jianli Company Limited (“Zhejiang Jianli”) to dispose of their entire equity interests in Jiangsu Fanli. Pursuant to the agreement, WSP China retained possession of certain assets of Jiangsu Fanli, including current assets and assumed all liabilities incurred before the disposal. On the same date, WSP China entered into an agreement with Zhejiang Jianli to purchase certain hot-rolling production assets. These two transactions were accounted for as nonmonetary transactions in accordance with an authoritative guidance and, accordingly, the exchanges of nonmonetary assets between WSP China and Zhejiang Jianli were recorded based on the fair value of the assets exchanged amounting to $13,913. A gain of $2,583 is resulted from non-monetary transactions which is included in other operating income. Given that Jiangsu Fanli is not wholly owned by WSP China before the disposal, the sales proceeds collected by WSP China on behalf of the non-controlling investors of $1,383 will be returned to the non-controlling investors. The Company determined that disposal of Jiangsu Fanli did not constitute a discontinued operation, as the operation capacity of Jiangsu Fanli was absorbed by other subsidiaries of the Company.

5.DISPOSAL OF CHAOYANG SEAMLESS

Pursuant to WSP China’s board of directors’ approval on November 21, 2011, WSP China entered into an agreement with a PRC individual to dispose of its entire 51% equity interest in Chaoyang Seamless on January 17, 2012 for a nominal cash consideration. Accordingly, the assets and liabilities of Chaoyang Seamless are separately reported as “assets and liabilities held for sale” as of December 31, 2011 at the lower of their carrying value or fair value less cost to sell. There have been no impairments related to Chaoyang Seamless. The carrying amounts of the major classes of assets and liabilities held for sale are as follows:

	As ofDecember 31,2011
Cash	$	18
Restricted cash	6,110
Other current assets	10,343
Property, plant and equipment, net	2,918
Land use rights	286
Goodwill	450
Other non-current assets	189
Total assets held for sale	$	20,314
Borrowings	$	14,442
Other payables and accrued liabilities	33,117
Total liabilities held for sale	$	47,559

The assets and liabilities shown in above table excluded due from and due to group company balances within WSP Holdings which are eliminated through consolidation.

The disposal transaction was completed in January 2012. WSP China, the Company’s wholly-owned subsidiary, has provided and may continue to provide guarantees for certain of Chaoyang Seamless’ bank loans until their maturity. These guarantees are counter-guaranteed by the personal assets of the current shareholders of Chaoyang Seamless. The gain on disposal of Chaoyang Seamless was $2,512, which was reported as “Gain on disposal of subsidiary” included in other operating income for the year ended December 31, 2012.

The Company determined that disposal of Chaoyang Seamless did not qualify as discontinued operations, as the Company had significant continuing direct cash outflows with Chaoyang Seamless after the disposal.

6.DISPOSAL OF PRODUCTION FACILITIES HELD BY HOUSTON OCTG

In November 2012, the Company sold its production facilities held by Houston OCTG to a third party for approximately $43,000, resulting in a loss of $5,051, which was reported in “General and administrative expenses” included in other operating income for the year ended December 31, 2012. The Company determined that disposal of production facilities did not qualify as discontinued operations, as significant continuing direct cash flows are generated by Houston OCTG after the disposal.

7.RESTRICTED CASH

Restricted cash mainly represents bank deposits used to pledge the bank acceptance notes. The Company entered into credit agreements with commercial banks in China (“endorsing banks”) which agree to provide credit within stipulated limits. Within the stipulated credit limits, the Company can issue bank acceptance notes to its suppliers as payments for the purchases. In order to issue bank acceptance notes, the Company is generally required to make initial deposits with the endorsing banks in amounts of certain percentage of the face amount of the bank acceptance notes to be issued by the Company. The cash in such accounts is restricted for use over the terms of the bank acceptance notes, which are normally three to six months.

12.IMPAIRMENT

The Company performed an impairment test on December 31, 2010 of certain asset groups for which there is an indication that the carrying amount of an asset may no longer be recoverable. In view of the drop in utilization rate of production facilities and operating losses, the Company performed the impairment test for certain asset groups namely, WSP China, Liaoyang Seamless, Songyuan Seamless, Mengfeng, Chaoyang Seamless and Houston OCTG on December 31, 2010. The carrying amounts of Chaoyang Seamless exceeded the future undiscounted net cash flows, therefore the Company recognized impairment loss of $14,544, $678, $1,468 and $365 on property, plant and equipment, intangible assets, prepaid lease payments for land use rights and deposit on acquisition of property, plant and equipment, respectively, as of December 31, 2010. The impairment loss was allocated to the long-lived assets of the group on a pro rata basis using the relative carrying amounts of those assets.

The Company performed the impairment tests on December 31, 2011 and 2012 for these similar asset groups with addition of Bazhou Seamless and WSP Pipe, except for Chaoyang Seamless which was classified as held for sale as of December 31, 2011 and Houston OCTG whose production facilities were sold in November 2012. The future undiscounted net cash flows of these asset groups exceeded their respective carrying amounts as of December 31, 2011 and 2012, respectively, therefore the Company recognized no impairment loss. The impairment tests were based in part on valuation analysis reports provided by American Appraisal China Limited, a third party valuation firm.

The Company performed an impairment test for goodwill on December 31, 2010 and Chaoyang Seamless constitutes a separate reporting unit on its own. Based on the results that the fair value of the reporting unit exceeds its carrying amount (following the impairment loss discussed above), the Company recognized no impairment loss on goodwill during the year ended December 31, 2010.

No impairment loss was identified on goodwill for the year ended December 31, 2011 as the carrying value of Chaoyang Seamless as a disposal group was less than its fair value less cost to sell, see Note 5.

15.EQUITY-METHOD INVESTMENT

On October 13, 2008, WSP China acquired a 29% equity interest of Wuxi Bright Wanbang Oil & Gas Anticorrosion Co., Ltd. (“Wuxi Bright Wanbang”) for $1,076 in cash. As the Company has the ability to exercise significant influence but does not have a controlling interest, the long-term investment was recorded using the equity method of accounting as follows:

	As ofDecember 31,2011			As ofDecember 31,2012
Investment cost	$	1,076		$	1,076
Share of loss	(350		)	(306		)
Exchange difference	91			93
	$	817		$	863

The excess of the cost of investment over the Company’s share of the fair value of net assets of the investee company’s identifiable assets, liabilities and contingent liabilities at the date of acquisition represented goodwill of $30 which was included in the carrying amount of the investment and was not amortized.

Short-term bank loans

The Company’s bank loans bear interest rates ranging from 3% to 12% per annum. Certain financial covenants (including maintaining a required debt to equity ratio) related to the long-term loans granted to a subsidiary in the PRC by certain banks were not met as of December 31, 2009 nor subsequently. The Company obtained a conditional waiver of such breach in July 2010 from each of the banks and agreed to enhance the capital of the subsidiary by $15,000 by March 31, 2011. However, the Company failed to enhance the capital of the subsidiary by the required deadline on March 31, 2011. The Company completed the capital injection in the subsidiary by April 7, 2011 and obtained a waiver from one of the banks dated April 26, 2011 who agreed not to accelerate the repayment of bank loans or reduce the loan credit facility. Notwithstanding the waiver, it is uncertain whether the Company would be able to meet the covenants in the future.

The Company did not meet certain ratios and thresholds for the year ended December 31, 2011 set forth in the financial covenants in the syndicated bank credit facility agreement described in Note 2(a). Additionally, the Company did not meet certain ratios and thresholds for the special observation period from July 1, 2011 to June 30, 2012 set forth in the financial covenants in this facility agreement. In December 2012, the bank syndicate waived the past breaches of financial covenants during the observation period and agreed to continue to fulfill the terms of the syndicated bank credit facility. However, the Company did not meet certain financial covenants for the year ended December 31, 2012. The bank syndicate held a review meeting and reached an agreement to waive the aforementioned breaches of financial covenants. The formal approval process within the bank syndicate is currently underway.

Furthermore, another of our subsidiaries, which commenced commercial production in the second half of 2011, is also in breach of its financial covenants under a project loan.

As a result, the corresponding loans in the total amount of $261,697 and $210,920 as described above were reclassified as current liability and included in “Borrowings — due with one year” at December 31, 2011 and 2012, respectively.

Loans received in connection with bills receivable discounted with recourse

The Company received loans from the banks and assigned certain bills receivables to the banks with recourse. The maturities of those loans are normally under 1 year.

Long-term bank loans

In 2009, the Company entered into various long-term loan agreements with various Chinese banks for an aggregated amount of $196,391, with $175,742 being unsecured loans, to facilitate its business expansion. Certain land use rights, property, plant and equipment were pledged to secure long-term loan of $20,649 from a bank, which has been repaid in full by the Company and renewed as short-term loan in June 2010. In 2010, the Company entered into additional long-term loan agreements with various Chinese banks for an aggregated amount of $67,646, with the entire amount being unsecured loans, to facilitate its business expansion. In 2011, the Company entered into additional long-term loan agreements with various Chinese banks and a foreign bank for an aggregated amount of $168,854 with the entire amount being secured loans. Certain long-term bank loans were reclassified as short-term bank loans as described above.

In 2012, the Company repaid $35,136 of matured long-term loans. Several banks have reached an agreement with us to adjust the repayment plans for some of long-term loans.

As of December 31, 2012, the principal payments for all long-term loans for the next five years are as follows:

2013	$	—
2014	15,910
2015	—
Thereafter	—
Total long-term bank loans	$	15,910

As of December 31, 2011 and 2012, the long-term loans bear either a benchmark interest rate announced by the People’s Bank of China, or at the premium up to 30% of such benchmark interest rate. In addition, the long-term loans interest rate of one of our overseas subsidiaries was determined by Singapore Interbank Offered Rate (“SIBOR”) plus margin and 2.5%.

Interest cost capitalized was $7,831, $15,430 and $12,657 for the years ended December 31, 2010, 2011 and 2012, respectively.

18.PRODUCT WARRANTY

The Company sells the majority of its products to customers along with unconditional repair or replacement warranties for a 12 month period from the date of purchase. The Company determines its estimated liability for warranty claims based on its experience of the amount of claims actually made. It is reasonably possible that the Company’s estimate of the accrued product warranty claims will change in the near term.

23.INCOME TAXES

WSP Holdings is a tax-exempted company incorporated in the Cayman Islands. FSHL is a tax-exempted company incorporated in the BVI.

FSHL’s subsidiaries registered in the PRC (the “PRC entities”) are subject to PRC Enterprise Income Tax (“EIT”) on the taxable income in accordance with the relevant PRC income tax laws.

On March 16, 2007, the National People’s Congress enacted a new enterprise income tax law, which took effect on January 1, 2008. The law applies a uniform 25% enterprise income tax rate to both foreign invested enterprises and domestic enterprises. According to the tax law, entities that qualify as high and new technology enterprises (“HNTE”) supported by the PRC government are allowed a 15% preferential tax rate instead of the uniform tax rate of 25%.

WSP China was officially granted the HNTE status in September 2008. Accordingly, WSP China has used the 15% preferential tax rate in the calculation of current and deferred tax balances because the company expects to retain the HNTE status in the foreseeable future.

Other PRC entities are subject to the 25% EIT rate since January 1, 2008.

Houston OCTG is subject to United States federal corporate income tax rate of 34% and Texas state margin tax.

The subsidiaries of FSHL that are tax residents in China, will be subject to the Chinese dividend withholding tax at 10% when these Chinese subsidiaries distribute dividends paid out of profits that arise on or after January 1, 2008. In 2009, following FSHL’s qualification as a tax resident company in the Hong Kong Special Administrative Region, a withholding tax at 5% is applicable on dividends paid to FSHL by these Chinese subsidiaries. The qualification for tax residency in the Hong Kong Special Administrative Region is subject to an annual application and approval process. FSHL has not made an application for the tax qualification in 2011 and 2012 due to operating losses of the Chinese subsidiaries.

A provision for PRC dividend withholding tax has been made based on a certain percentage of the 2010 and 2011 undistributed earnings of the Company’s PRC subsidiaries, which are expected to be distributed as dividends to the parent companies. There were no remaining undistributed earnings of the Company’s PRC subsidiaries as of December 31, 2011 and 2012 due to the losses incurred since 2010.

The calculation of income taxes reflects the status of WSP Holdings and FSHL as non-China tax resident companies. The tax residency of a company is normally a question of fact. For a company, such as WSP Holdings and FSHL, which have been established outside China, tax residency will only be in China if the location of effective management of the company is in China. China for this purpose does not include Hong Kong, Macau, or Taiwan. Because the concept of tax residency is still relatively new in China, it is possible that the tax authorities could in the future assert that WSP Holdings and/or one or more of its non-Chinese subsidiaries are tax residents in China. In the event that this occurs, WSP Holdings or FSHL will become subject to the PRC Enterprise Income Tax Law on its worldwide income. This would cause any income WSP Holdings and FSHL earned to be subject to China’s 25% EIT. As there is an exemption for any dividends received by a China tax resident company from another tax resident company, such taxable income would not include any dividends from the Chinese subsidiaries.

The Company has made its assessment of the level of tax authority for each tax position (including the potential application of interest and penalties) based on the technical merits, and has measured the unrecognized tax benefits associated with the tax positions. As of January 1, 2010, the Company had a beginning amount of $5,563 of unrecognized tax benefits carried forward from the year ended December 31, 2009 and had additional unrecognized tax benefits of $3,698 related to net operating loss carryforwards and certain government subsidies as of December 31, 2010. As of December 31, 2011 and 2012, the Company had no additional unrecognized tax benefits.

The aforementioned liability is recorded as non-current liabilities because the related payment is not anticipated within one year of the balance sheet date. The Company classifies interest and/or penalties related to income tax matters in income tax expense. A reconciliation of the beginning and ending amount of unrecognized tax benefits for 2010, 2011 and 2012 is as follows:

Balance at January 1, 2010	$	5,563
Additions based on tax positions related to 2010	3,698
Interest	2,558
Balance at December 31, 2010	$	11,819
Additions based on tax positions related to 2011	—

Additions based on tax positions related to 2012	—
Interest and penalties	792
Balance at December 31, 2012	$	13,555

There are no ongoing examinations by taxing authorities at this time. The Company’s PRC subsidiaries’ tax years starting from 2008 remain open for non-transfer pricing matters and from 2003 remain open for transfer pricing matters. The Company does not anticipate any significant change within the next 12 months of its uncertain tax positions, except the continuous interest and penalty.

(c)In April 2009, seven companies and the United Steelworkers Union in the United States of America filed a petition with the International Trade Commission (“ITC”) and the Department of Commerce (“DOC”), alleging that China-based OCTG manufacturers unfairly dumped OCTG products in the United States market and that Chinese producers were benefitting from massive government subsidies. WSP China was named as one of the major Chinese exporters of the OCTG products to the United States and was included as one of the mandatory respondent companies to the United States government’s countervailing duty investigation. On September 8, 2009, a preliminary determination was issued with a countervailing duty rate of 24.92% assigned to WSP China. On December 7, 2009, the DOC published its final determination in the countervailing duties investigation with a rate of 14.61% assigned to WSP China. The rate was subsequently changed to 14.95% in January 2010 due to certain ministerial errors made by the DOC. WSP China was not classified as a mandatory respondent to the anti-dumping investigation and participated in this case as a separate rate respondent. In November 2009, the Company received a preliminary anti-dumping rate of 36.53% which was based on the average dumping rates of other OCTG producers that were selected as mandatory respondents. On April 9, 2010, the DOC announced its final determination in the anti-dumping investigation with a rate of 29.94% assigned to WSP China. In May 2010, the ITC made a final ruling which requires all Chinese exports of OCTG products to the United States, including WSP China’s products, be charged up to about 32.07% anti-dumping duties and 14.95% countervailing duties.

The plaintiffs claimed total damages in the amount of approximately $15,000. The trial date for this case has not been set. The Company intends to vigorously defend itself against the claims. In connection with this case, certain landowners who were affected by the failed oil and gas well operation mentioned above, have filed a lawsuit against Chesapeake Louisiana, L.P. in the District Court of Desoto Parish, Louisiana in November 2009. Such landowners claimed damages up to $50 for each of them and their minor children in a group of 36 individuals. In May 2010, the plaintiffs amended the petition to name WSP China as a co-defendant in the lawsuit. In October 2012, the Company paid $13 in settlement of the case.

(h)In connection with a lawsuit brought by Mewbourne Oil Company against Trident Steel Corporation for selling defective casing pipes, in August 2010, Trident Steel Corporation filed a third-party petition against Minmetals, Inc. and WSP China in the District Court of Lipscomb County, Texas, stating that it fulfilled the Mewbourne Oil Company’s purchase order using the casing pipes manufactured by Minmetals, Inc. and WSP China.

The total of these past due amounts and damages is estimated to be approximately $13,990, of which $2,780 have already been settled. As a result of these claims and lawsuits, certain of the Company’s bank accounts and assets were frozen by court order.

(k)In August 2013, Energy Holdings, Inc. and Texas Energy Operations, LC brought a lawsuit against WSP Holdings, WSP China, Houston OCTG, J&B Tubular Pipe Supply, Inc., Texas Tubular Sales, LP, and National Oilwell Varco, LP d/b/a NOV Tuboscope in a district court in Dallas County, Texas. Plaintiffs brought suit against defendants for improper manufacture, sales and ultimate failure of oil and gas well casing that plaintiffs installed in the Gibbons #1 well in Jackson County, Oklahoma. The substantial discovery will take place in 2014 and the potential liability will be assessable as the discovery in the case proceeds.

In addition to the contingencies mentioned above, the Company is subject to claims and legal proceedings that arise in the ordinary course of its business. Each of these matters is subject to various uncertainties, and it is possible that some of these matters may be decided unfavorably to the Company. Based on the information currently available, the Company was unable to make a reasonable estimate of any further liability because of the uncertainty related to the outcome and/or the amount or range of loss. Accordingly, the Company did not accrue any provision for the contingencies as of December 31, 2012, other than those settled as described above.

Bill financing

The Company utilizes a portion of its credit facilities from certain banks as bill financing to fund a portion of its working capital requirements and business operational needs.

The Company entered into certain bill financing arrangements where the amounts of bank and commercial acceptance notes drawn down on the banks under the facilities were greater than its real expectation of purchasing needs from suppliers, which included both the Company’s subsidiaries and third parties. On some occasions, the same purchase contracts (required for the issuance of bank acceptance notes under the bill financing facilities) were presented to two or more different banks to obtain financing. A portion of the notes the Company issued to its subsidiaries and third-party suppliers were then presented by the relevant suppliers to the banks for collection of an amount equal to the face value of the notes after deducting interest. Cash received from the notes presented in excess of the actual amount of purchases was then provided to the Company and utilized for operational purposes. Such transactions have been accounted as financing transactions with the banks.

The total amount of the bill financing, being the difference between the aggregate amount of such bank and commercial acceptance notes issued and the aggregate amount of related actual purchases, was approximately RMB 1,419,000 ($225,200), RMB 757,850 ($120,571) and RMB 1,190,966 ($193,716) in 2011, 2012 and the nine months ended September 30, 2013, respectively. Excluding the cash deposits that the Company paid upfront to the endorsing banks pursuant to the arrangements, the funding the Company obtained from the banks through this kind of bill financing in 2011, 2012 and the nine months ended September 30, 2013, was estimated to be approximately RMB 323,600 ($51,400), RMB 213,180 ($33,916) and RMB 693,822 ($112,853), respectively.

In 2012, additionally, for purposes of raising financing from a number of commercial banks, WSP China, Liaoyang Seamless and Songyuan Seamless entered into a number of intragroup transactions, under which WSP China sold approximately RMB 251,000 ($40,100) worth of goods to Liaoyang Seamless, Liaoyang Seamless sold approximately RMB 252,000 ($40,300) of goods to Songyuan Seamless and Songyuan Seamless sold approximately RMB 252,000 ($40,300) of goods to WSP China. Official sales invoices were issued for these transactions. However, physical delivery of the underlying goods in these transactions did not occur. As these transactions were intragroup, they did not have an overall impact on our consolidated revenues and did not result in additional tax payable, although the PRC GAAP reports of each of these three respective individual entities would have reflected sales not supported by physical delivery of the underlying goods. These sales invoices allowed our subsidiaries to obtain additional bill financing from a number of commercial banks. Due to the nature of these transactions, these commercial banks may declare any of our borrowings to become immediately due and payable and terminate our credit facilities so that no additional borrowings can be obtained. If any of these borrowings become immediately due and payable, we may not have the means to repay them.

Anti-dumping

In April 2009, seven U.S. companies and the United Steelworkers Union filed a petition with the U.S. International Trade Commission, or the ITC, and the U.S. Department of Commerce, or the DOC, alleging that China-based OCTG manufacturers unfairly dumped OCTG products in the U.S. market and that Chinese producers were benefitting from massive government subsidies. Wuxi Seamless Oil Pipes Company Limited, or WSP China, was named as one of the major exporters of OCTG products from China. In June 2009, we were included as one of the mandatory respondent companies to the United States government’s countervailing duty investigation. On September 8, 2009, a preliminary determination was issued with a countervailing duty rate of 24.92% assigned to WSP China. On December 7, 2009, the DOC published its final determination in the countervailing duties investigation with a rate of 14.61% assigned to WSP China. The rate was subsequently changed to 14.95% in January 2010 due to certain ministerial errors made by the DOC. We were not selected as a mandatory respondent to the anti-dumping investigation and participated in this case as a separate rate respondent. In November 2009, we received a preliminary dumping rate of 36.53%, which was based on the average dumping rates of other OCTG producers that were selected as mandatory respondents. In December 2009, this rate was amended to 96.51% due to certain ministerial errors made by the DOC. On April 9, 2010, the DOC announced its final determination in the anti-dumping investigation with a rate of 29.94% assigned to WSP China. In May 2010, the ITC made a final ruling which requires all Chinese exports of OCTG products to the United States, including WSP China’s products, be subject up to approximately 32.07% of anti-dumping duties and 14.95% of countervailing duties. The anti-dumping and countervailing duties are applied to all Chinese exports of OCTG products to the United States starting from the date of the DOC’s preliminary determinations. WSP China has not exported OCTG products to the United States after the date of the DOC’s preliminary determinations. The anti-dumping and countervailing duties will apply to us if WSP China exports OCTG products to the United States in the future and we are not subject to any other penalties or fines. In 2010, 2011 and 2012, products sold to the United States by our subsidiaries accounted for 9.7%, 6.3% and 9.3% of our net revenues, respectively. The decrease in export revenue of products sold to the United States as a percentage of our net revenues mainly was attributable to the effect of anti-dumping and countervailing duties on the subject goods. As a result of the proceedings, our sales in the U.S. suffered and our results of operations have been materially and adversely affected.

There may be similar actions taken in the future in other countries against PRC-made seamless OCTG products. Any actions filed against us with respect to the products we sell, even without merit, may divert significant company resources and management attention, have an adverse impact on the prices and sales of our products in the relevant countries and adversely affect our business prospects and results of operations. If any decision is entered against us in such an action, we may be subject to additional tariff liabilities and our overseas sales may be materially and adversely affected. Additionally, in July 2013, nine US manufacturers sought anti-dumping and countervailing duty investigations on OCTG products from nine countries, including Thailand. In August 2013, the ITC announced that it had found reasonable grounds to pursue an anti-dumping case against the nine countries and that the DOC was investigating the matter.  If anti-dumping duties are imposed on Thailand, our business in Thailand and the operations of WSP Pipe may be significantly and adversely affected.

Additionally, in 2012, we have identified an immaterial amount of goods originating from China that were incorrectly imported to the United States. We are presently repatriating the goods. We are unable to estimate the likelihood that legal liability will arise as a result of the incorrect importation of these goods, including any duties that may be imposed by regulators, or the amount of liability that we would incur should any legal proceedings take place.

30.        MAINLAND CHINA CONTRIBUTION PLAN

Full time employees of the Company in the PRC participate in a government mandated multiemployer defined contribution plan pursuant to which certain pension benefits, medical care, unemployment insurance, employee housing fund and other welfare benefits are provided to employees. PRC labor regulations require the Company to accrue for these benefits based on certain percentages of the employees’ salaries. The total contributions for such employee benefits were $4,891, $7,540 and $6,909, for the years ended December 31, 2010, 2011 and 2012, respectively.

31.        STATUTORY NON-DISTRIBUTABLE RESERVES

The principal regulations in the PRC governing distribution of dividends paid by wholly foreign-owned enterprises include:

·             Wholly Foreign-Owned Enterprise Law (1986) as amended; and

·             Wholly Foreign-Owned Enterprise Law Implementation Rules (1990) as amended.

Under these regulations, wholly foreign-owned enterprises in the PRC may pay dividends only out of their accumulated profits, if any, determined in accordance with the PRC accounting standards and regulations.

In addition, according to the Company Law in the PRC, companies are required to set aside 10% of their after-tax profit to general reserves each year, based on the PRC accounting standards, until the cumulative total of such reserves reaches 50% of the registered capital. These general reserves are not distributable as cash dividends to equity owners.

In addition, a PRC company may set aside other amounts determined at its discretion. Once set aside, these amounts can only be used for designated purpose and are not available for future distribution to, owners or shareholders. The general reserves and discretionary reserves are collectively referred to as statutory non-distributable reserves.

Due to the loss position, no appropriations were made by WSP China for the years ended December 31, 2010, 2011 and 2012, respectively. As of December 31, 2012, the statutory non-distributable reserves of WSP China were $37,119.

32.        SUBSEQUENT EVENTS

In January 2013, Songyuan Seamless entered into an Equity Transfer Agreement with Liaoning Steel Pipe Co., Ltd. (“Liaoning Pipe”) to acquire all of Liaoning Steel’s 30% equity interest in Liaoyang Seamless for a total consideration of RMB 48,950 (approximately $7,800). The transaction was funded by selling certain assets of Liaoyang Seamless to Liaoning Pipe. Liaoyang Seamless also entered into a lease agreement with Liaoning Pipe to lease back these assets to continue Liaoyang Seamless’s operations. The term of the lease is for three years and expires on December 31, 2015 with monthly rent payment of RMB 434 (approximately $69). The acquisition transaction was completed in July 2013.

On February 21, 2013, the Company announced that it entered into an Agreement and Plan of Merger (the “Merger Agreement”) with WSP OCTG GROUP Ltd. (“Parent”), a company owned by H.D.S. Investments LLC, and JM OCTG GROUP Ltd. (“Merger Sub”), a company with limited liability and a direct wholly-owned subsidiary of Parent. Subject to satisfaction or waiver of the closing conditions in the Merger Agreement, Merger Sub will merge with and into the Company, with the Company continuing as the surviving corporation (the “Merger”). Pursuant to the Merger Agreement, each of the Company’s ordinary shares issued and outstanding immediately prior to the effective time of the Merger (the “Shares”) will be cancelled and cease to exist in exchange for the right to receive $0.32 without interest, and each ADS, which represents ten ordinary shares, will represent the right to surrender the ADS in exchange for $3.20 in cash without interest, except for (a) Shares held of record by Expert Master Holdings Limited (“EMH”), a company wholly-owned by Mr. Piao and UMW China Ventures (L) Ltd. (“UMW”), which will be contributed to Parent immediately prior to the Merger in exchange for equity interests of Parent, and (b) Shares owned by shareholders who have validly exercised and have not effectively withdrawn or lost their rights to dissent from the Merger under the Cayman Islands Companies Law (the “Dissenting Shares”), which will be cancelled for the right to payment of fair value of the Dissenting Shares in accordance with the Cayman Islands Companies Law.

One of our subsidiaries had a bank loan with a restrictive covenant that requires the Company to keep its status as a New York Stock Exchange traded company. The above going private transaction, if completed, would trigger the covenant violation. The related debt is already classified as current liability due to other covenant violations. The Company is currently in discussions with the bank regarding obtaining a waiver for this requirement.

In March 2013, the Company entered into an agreement with a third party to transfer its entire 29% equity interests in Wuxi Bright Wanbang Oil & Gas Anticorrosion Co., Ltd., for a total consideration of RMB 3,480 (approximately $560), which resulted in a loss on disposal of RMB1,043 (approximately $170) reflected in its results of operations for the first quarter of 2013.

In October 2013, the Company held a special board meeting and approved to waive the payment of RMB 27,000 (approximately $4,300) owed by Chaoyang Seamless to Bazhou Seamless and RMB 78,500 (approximately $12,500) owed by Chaoyang Seamless to Liaoyang Seamless. In anticipation of the waiver, the Company recorded additional bad debt expense of RMB 105,500 ($16,800) in its results of operations for the first half year of 2013.

Notes to Additional Information

1.Basis for Preparation

The Condensed Financial Information of the Company only has been prepared using the same accounting policies as set out in the Company’s consolidated financial statements except that the Company has used equity method to account for its investment in its subsidiary, FSHL.

2.Investments in Subsidiaries

The Company and its subsidiaries were included in the consolidated financial statements where inter-company balances and transactions were eliminated upon consolidation. For purpose of the Company’s stand-alone financial statements, its investments in subsidiaries were reported using the equity method of accounting. The Company’s share of income and losses from its subsidiaries were reported as shares of earnings (loss) of subsidiaries in the accompanying financial statements. The Company will cease to record any loss incurred by the subsidiaries when the Company’s investments in the subsidiaries are reduced to zero as the Company does not have the obligations to fund the loss of the subsidiaries.
