Item 3.D.  Risk Factors

You should carefully consider the risks described below.

The global economic downturn in recent years reduced worldwide demand for steel products in 2008 and 2009. While the rate of deterioration of the global economy slowed in the second half of 2009 and the global economy showed some signs of stabilization and improvement in 2010 and the first half of 2011, there can be no assurance that such recovery will continue.

Difficulties affecting the U.S. and global financial sectors, adverse conditions and volatility in the U.S. and worldwide credit and financial markets, fluctuations in oil and commodity prices and the

4

general weakness of the U.S. and global economy have increased the uncertainty of global economic prospects in general and have adversely affected the global and Korean economies. The global economic downturn in recent years had a pronounced negative effect on the global demand for steel products and their prices in 2008 and 2009. While the rate of deterioration of the global economy slowed in the second half of 2009 and the global economy showed some signs of stabilization and improvement in 2010 and the first half of 2011, the overall prospects for the Korean and global economy in the second half of 2011 and beyond remain uncertain.

In response to sluggish demand from our customers in industries adversely impacted by the deteriorating global economic conditions in the second half of 2008, such as the automotive and construction industries, we reduced our crude steel production and sales prices in December 2008 and the first quarter of 2009. Signs that the pace of deterioration in market conditions had slowed began to appear in the second quarter of 2009, however, and demand from certain segments of our customer base, including the domestic automotive and construction industries, showed signs of recovery starting in the second quarter of 2009. In response, we began to incrementally increase our crude steel production starting in April 2009 and our production level normalized in the second half of 2009. Our crude steel production decreased from 34.7 million tons in 2008 to 31.7 million tons in 2009 but rebounded to 35.3 million tons in 2010. Prices of our steel products also gradually recovered starting in the third quarter of 2009.

However, there can be no assurance that such recovery will continue, and we may decide to adjust our future crude steel production or our sales prices on an on-going basis subject to market demand for our products, the production outlook of the global steel industry and global economic conditions in general. Deterioration of market conditions may result in changes in assumptions underlying the carrying value of certain assets, which in turn could result in impairment of such assets, including intangible assets such as goodwill. We expect fluctuation in demand for our steel products to continue to prevail at least in the near future, which may adversely affect our business, results of operations or financial condition.

Korea is our most important market, and our current business and future growth could be materially and adversely affected if economic conditions in Korea deteriorate.

We are incorporated in Korea, and a substantial portion of our operations and assets are located in Korea. Korea is our most important market, accounting for 56.4% of our total sales volume of steel products in 2010. Domestic demand for our products is affected by the condition of major steel consuming industries, such as construction, shipbuilding, automotive, electrical appliances and downstream steel processors, and the Korean economy in general. In addition, the trading operations of Daewoo International Corporation are affected by the general level of trade between Korea and other countries, which in turn tends to fluctuate based on general conditions in the Korean and global economies. As a result, we are subject to political, economic, legal and regulatory risks specific to Korea.

The economic indicators in Korea in recent years have shown mixed signs, and future growth of the Korean economy is subject to many factors beyond our control. Recent difficulties affecting the U.S. and global financial sectors, adverse conditions and volatility in the worldwide credit and financial markets, fluctuations in oil and commodity prices and the general weakness of the U.S. and global economy have increased the uncertainty of global economic prospects in general and have adversely affected, and may continue to adversely affect, the Korean economy. Due to recent liquidity and credit concerns and volatility in the global financial markets, the value of the Won relative to the Dollar has also fluctuated significantly in recent years. Furthermore, as a result of adverse global and Korean economic conditions, there has been continuing volatility in the stock prices of Korean companies. Any future deterioration of the Korean or global economy could adversely affect our business, financial condition and results of operations.

5

Developments that could have an adverse impact on Korea’s economy in the future include:

•     difficulties in the housing and financial sectors in the United States and elsewhere and increased sovereign default risks in select countries and the resulting adverse effects on the global financial markets;

•     declines in consumer confidence and a slowdown in consumer spending;

•     adverse changes or volatility in foreign currency reserve levels, commodity prices (including oil prices), exchange rates (including fluctuation of the Dollar or Japanese Yen exchange rates or revaluation of the Chinese renminbi), interest rates or stock markets;

•     continuing adverse conditions in the economies of countries that are important export markets for Korea, such as the United States, Japan and China, or in emerging market economies in Asia or elsewhere;

•     increasing delinquencies and credit defaults by retail and small- and medium-sized enterprise borrowers;

•     the continued emergence of the Chinese economy, to the extent its benefits (such as increased exports to China) are outweighed by its costs (such as competition in export markets or for foreign investment and the relocation of the manufacturing base from Korea to China);

•     the economic impact of any pending or future free trade agreements;

•     social and labor unrest;

•     substantial decreases in the market prices of Korean real estate;

•     a decrease in tax revenues and a substantial increase in the Government’s expenditures for fiscal stimulus measures, unemployment compensation and other economic and social programs that, together, would lead to an increased Government budget deficit;

•     financial problems or lack of progress in the restructuring of Korean conglomerates, other large troubled companies, their suppliers or the financial sector;

•     loss of investor confidence arising from corporate accounting irregularities and corporate governance issues at certain Korean conglomerates;

•     geo-political uncertainty and risk of further attacks by terrorist groups around the world;

•     the occurrence of severe health epidemics in Korea and other parts of the world;

•     deterioration in economic or diplomatic relations between Korea and its trading partners or allies, including deterioration resulting from trade disputes or disagreements in foreign policy;

•     political uncertainty or increasing strife among or within political parties in Korea;

•     hostilities involving oil producing countries in the Middle East and any material disruption in the supply of oil or increase in the price of oil;

•     the occurrence of severe earthquakes, tsunamis or other natural disasters in Korea and other parts of the world, particularly in trading partners (such as the March 2011 earthquake in Japan, which also resulted in the release of radioactive materials from a nuclear plant that had been damaged by the earthquake); and

•     an increase in the level of tensions or an outbreak of hostilities between North Korea and Korea or the United States.

6

We rely on export sales for a significant portion of our total sales. Adverse economic and financial developments in Asia in the future may have an adverse effect on demand for our products in Asia and increase our foreign exchange risks.

Our export sales and overseas sales to customers abroad accounted for 43.6% of our total sales volume of steel products in 2010. Our export sales volume to customers in Asia, including China, Japan, Indonesia, Thailand and Malaysia, accounted for 61.9% of our total export sales volume for steel products in 2010, and we expect our sales to these countries, especially to China, to remain important in the future. Accordingly, adverse economic and financial developments in these countries may have an adverse effect on demand for our products. Economic weakness in Asia may also adversely affect our sales to the Korean companies that export to the region, especially companies in the construction, shipbuilding, automotive, electrical appliances and downstream steel processing industries. Weaker demand in these countries, combined with addition of new steel production capacity, particularly in China, may also reduce export prices in Dollar terms of our principal products. We attempt to maintain and expand our export sales to generate foreign currency receipts to cover our foreign currency purchases and debt service requirements. Consequently, any decrease in our export sales could also increase our foreign exchange risks.

Depreciation of the value of the Won against the Dollar and other major foreign currencies may have a material adverse effect on the results of our operations and on the price of the ADSs.

The Won has fluctuated significantly against major currencies in recent years. The market average exchange rate, as announced by the Seoul Money Brokerage Services, Ltd., depreciated from Won 938.2 to US$1.00 as of December 31, 2007 to Won 1,573.6 to US$1.00 as of March 3, 2009 but appreciated to Won 1,075.0 to US$1.00 as of June 23, 2011. Depreciation of the Won may materially affect the results of our operations because, among other things, it causes:

•     an increase in the amount of Won required for us to make interest and principal payments on our foreign currency-denominated debt, which accounted for approximately 53.5% of our total long-term debt (excluding discounts on debentures issued and including current portion) as of December 31, 2010;

•     an increase in Won terms in the costs of raw materials and equipment that we purchase from overseas sources and a substantial portion of our freight costs, which are denominated primarily in Dollars; and

•     foreign exchange translation losses on liabilities, which lower our earnings for accounting purposes.

Appreciation of the Won, on the other hand, (i) causes our export products to be less competitive by raising our prices in Dollar terms and (ii) reduces net sales and accounts receivables in Won from export sales, which are primarily denominated in Dollars. However, because of the larger positive effects of the appreciation of the Won (i.e., the reverse of the negative effects caused by the depreciation of the Won, as discussed above), appreciation of the Won generally has a positive impact on our results of operations.

Fluctuations in the exchange rate between the Won and the Dollar will also affect the Dollar equivalent of the Won price of the shares of our common stock on the KRX KOSPI Market and, as a result, will likely affect the market price of the ADSs. These fluctuations will also affect the Dollar conversion by the depositary for the ADRs of cash dividends, if any, paid in Won on shares of common stock represented by the ADSs.

We are dependent on imported raw materials, and significant increases in market prices of essential raw materials could adversely affect our margins and profits.

We purchase substantially all of the principal raw materials we use from sources outside Korea, including iron ore and coal. POSCO imported approximately 49.3 million dry metric tons of iron ore and 26.2 million wet metric tons of coal in 2010. Iron ore is imported primarily from Australia, Brazil and South Africa. Coal is imported primarily from Australia, Canada and China. Although we have not experienced significant unanticipated supply disruptions in the past, supply disruptions, which could be caused by political or other events in the countries from which we import these materials, could adversely affect our operations.

In addition, we are particularly exposed to increases in the prices of coal, iron ore and nickel, which represent the largest components of our cost of goods sold. The prices of our key raw materials have fluctuated significantly in recent years. For example, the average market price of coal per wet metric ton (benchmark free on board price of Australian premium hard coking coal) was US$250 in 2008, US$172 in 2009 and US$191 in 2010. The average market price of iron ore per dry metric ton (free on board price of Platts Iron Ore index with iron (Fe) 62% content) was US$126 in 2008, US$68 in 2009 and US$136 in 2010. Our long-term supply contracts generally have terms of three to ten years and provide for periodic price adjustments to the then-market prices. We typically adjust the prices on a quarterly basis and maintain approximately one month of inventory of raw materials. Future increases in prices of our key raw materials and our inability to pass along such increases to our customers could adversely affect our margins and profits. Increased prices may also cause potential customers to defer purchase of steel products, which would have an adverse effect on our business, financial condition and results of operations.

Excess capacity and oversupply in the global steel industry may adversely affect our profitability.

In recent years, driven in part by strong growth in steel consumption in the developing world, particularly in China, the global steel industry has experienced renewed interest in expansion of steel production capacity. China is the largest steel producing country in the world by a significant margin, with the balance between its domestic production and demand being an important factor in the determination of global steel prices. In addition, Chinese steel exports may have a significant impact on steel prices in markets outside of China, including Korea.

The increased production capacity, combined with a decrease in demand due to the recent slowdown of the global economy, has resulted in production over-capacity in the global steel industry. Production over-capacity in the global steel industry may intensify if the slowdown of the global economy is prolonged or demand from developing countries that have experienced significant growth in the past several years does not meet the recent growth in production capacity. Production over-capacity in the global steel industry is likely to:

•     reduce export prices in Dollar terms of our principal products, which in turn may reduce our sales prices in Korea;

•     increase competition in the Korean market as foreign producers seek to export steel products to Korea as other markets experience a slowdown;

•     negatively affect demand for our products abroad and our ability to expand export sales; and

•     affect our ability to increase steel production in general.

There is no assurance that we will be able to continue to compete successfully in this economic environment or that the prolonged slowdown of the global economy or production over-capacity will not have a material adverse effect on our business, results of operations or financial condition.

We may not be able to successfully execute our diversification strategy.

In part to prepare for the eventual maturation of the Korean steel market, our overall strategy includes securing new growth engines by diversifying into new businesses related to our steel operations that we believe will offer greater potential returns, such as liquefied natural gas (“LNG”) production, logistics and magnesium coil and sheet production, as well as entering into new businesses not related to our steel operations such as power generation, development of alternative energy, advanced materials and energy resources, information and technology related consulting services and wireless broadband Internet access service. From time to time, we may selectively acquire or invest in companies to pursue such diversification strategy. On September 20, 2010, we acquired a 68.15% interest in Daewoo International for Won 3.37 trillion. Daewoo International is a global trading company that primarily engages in trading of steel and raw materials as well as investing in energy and mineral development projects. It also manufactures and sells textiles, operates a department store in Korea, and holds a 24% interest in Kyobo Life Insurance, Korea’s third largest life insurance company in terms of market share in 2010. We submitted a letter of intent to Asiana Airlines Inc. and Daewoo E&C Co., Ltd. on March 4, 2011 and our Board of Directors decided on May 13, 2011 to participate in the final bid for the acquisition of a controlling stake in Korea Express Co., Ltd., a leading logistics company in Korea. Korea Express is being sold in an auction process and the preferred bidder is expected to be selected in the second quarter of 2011.

The success of the overall diversification strategy will depend, in part, on our ability to realize the growth opportunities and anticipated synergies. The realization of the anticipated benefits depends on numerous factors, some of which are outside our control, including the availability of qualified personnel, establishment of new relationships and expansion of existing relationships with various customers and suppliers, procurement of necessary technology and know-how to engage in such businesses and access to investment capital at reasonable costs. The realization of the anticipated benefits may be impeded, delayed or reduced as a result of numerous factors, some of which are outside our control. These factors include:

•     difficulties in integrating the operations of the acquired business, including information and accounting systems, personnel, policies and procedures, and in reorganizing or reducing overlapping operations, marketing networks and administrative functions, which may require significant amounts of time, financial resources and management attention;

•     unforeseen contingent risks or latent liabilities relating to the acquisition that may become apparent in the future;

•     difficulties in managing a larger business; and

•     loss of key management personnel or customers.

Accordingly, we cannot assure you that our diversification strategy can be completed profitably or that the diversification efforts will not adversely affect our combined business, financial condition and results of operations.

Consolidation and new market entrants in the global steel industry may increase competition.

In recent years, there has been a trend toward industry consolidation among our competitors. For example, consolidation of Mittal and Arcelor in 2006 has created a company with approximately 10% of global steel production capacity. Competition from global steel manufacturers with expanded production capacity such as ArcelorMittal and new market entrants, especially from China and India, have resulted in significant price competition and may result in declining margins and reductions in revenue. Our larger competitors may use their resources, which may be greater than ours, against us in a variety of ways, including by making additional acquisitions, investing more aggressively in product development and capacity and displacing demand for our export products.

9

Competition from steel substitute materials may reduce demand for steel products.

Steel competes with other natural and synthetic materials that may be used as steel substitutes, such as aluminum, cement, composites, glass, plastic and wood. Government regulatory initiatives mandating the use of such materials instead of steel, whether for environmental or other reasons, as well as the development of attractive alternative substitutes for steel products, may reduce demand for steel products and adversely affect our business, results of operations or financial condition.

Expansion of our production operations abroad is important to our long-term success, and our limited experience in the operation of our business outside Korea increases the risk that our international expansion efforts will not be successful.

We conduct international trading and construction operations abroad, and our business relies on a global trading network comprised of overseas subsidiaries, branches and representative offices. Although many of our subsidiaries and overseas branches are located in developed countries, we also operate in numerous countries with developing economies. In addition, we intend to continue to expand our production operations internationally by carefully seeking out promising investment opportunities, particularly in China, India, and Southeast Asia, in part to prepare for the eventual maturation of the Korean steel market. We may enter into joint ventures with foreign steel producers that would enable us to rely on these businesses to conduct our operations, establish local networks and coordinate our sales and marketing efforts abroad. To the extent that we enter into these arrangements, our success will depend in part on the willingness of our partner companies to dedicate sufficient resources to their partnership with us.

In other situations, we may decide to establish manufacturing facilities by ourselves instead of relying on partners. The demand and market acceptance for our products produced abroad are subject to a high level of uncertainty and are substantially dependent upon the market condition of the global steel industry. We cannot assure you that our international expansion plan will be profitable or that we can recoup the costs related to such investments.

Expansion of our trading, construction and production operations abroad requires management attention and resources. In addition, we face additional risks associated with our expansion outside Korea, including:

•     challenges caused by distance, language and cultural differences;

•     higher costs associated with doing business internationally;

•     legal and regulatory restrictions, including foreign exchange controls that might prevent us from repatriating cash earned in countries outside Korea;

•     longer payment cycles in some countries;

•     credit risk and higher levels of payment fraud;

•     currency exchange risks;

•     potentially adverse tax consequences;

•     political and economic instability; and

•     seasonal reductions in business activity during the summer months in some countries.

The March 11, 2011 natural disaster in Japan and its continuing effects could materially adversely affect our business.

On March 11, 2011, Japan experienced a 9.0 moment magnitude scale undersea earthquake, which triggered tsunami waves that resulted in extensive and severe infrastructure damage throughout the eastern coast of Japan. The earthquake also caused a number of nuclear accidents, including an

10

ongoing major accident at the Fukushima nuclear power plant, making it the most costly natural disaster on record. Some of our Japanese suppliers of manufacturing equipment as well as our Japanese customers have temporarily suspended their operations due to the March 2011 natural disaster, and some continue to be affected by unreliable power, shipping constraints, problems with their suppliers, and the continuing effects. Although we believe that we have sufficient access to manufacturing equipment typically sourced from Japan to cover our short-term needs, we may experience shortages or delays in the supply of manufacturing equipment in the long-term. If we are not able to obtain such equipment from alternative sources on a timely basis or at commercially reasonable terms, or at all, it could adversely impact the production of our products. In addition, sales to our customers located in Japan represented 18.4% of our total export sales volume for steel products in 2008, 10.9% in 2009 and 11.0% in 2010, and demand from such customers may decrease as a result of the slowdown in their business operations due to the recent natural disaster and its continuing effects.

We may from time to time engage in acquisitions for which we may be required to seek additional sources of capital.

From time to time, we may selectively acquire or invest in companies or businesses that may complement our business. In order to finance these acquisitions, we intend to use cash on hand, funds from operations, issuances of equity and debt securities, and, if necessary, financings from banks and other sources as well as entering into consortiums with financial investors. However, no assurance can be given that we will obtain sufficient financing for such acquisitions or investments on terms commercially acceptable to us or at all. We also cannot assure you that such financings and related debt payment obligations will not have a material adverse impact on our financial condition, results of operations or cash flow.

Further increases in, or new impositions of, anti-dumping or countervailing proceedings may have an adverse impact on our export sales.

Currently, several of our products are subject to anti-dumping or countervailing proceedings, including in the United States and several emerging markets. Our products that have been subject to anti-dumping or countervailing proceedings in the aggregate have not accounted for a material portion of our total sales in recent years. However, there can be no assurance that increases in, or new impositions of, anti-dumping duties, countervailing duties, quotas or tariffs on our sales of products abroad may not have a material adverse impact on our exports in the future. See “Item 4. Information on the Company — Item 4.B. Business Overview — Markets — Exports.”

Cyclical fluctuations based on macroeconomic factors may adversely affect POSCO E&C’s business and performance.

In order to complement our steel operations, we engage in engineering and construction activities through POSCO Engineering & Construction Co., Ltd. (“POSCO E&C”), an 89.5%-owned subsidiary. The engineering and construction segment, which accounted for approximately 7.0% of our consolidated sales in 2010 after adjusting for inter-company sales, is highly cyclical and tends to fluctuate based on macroeconomic factors, such as consumer confidence and income, employment levels, interest rates, inflation rates, demographic trends and policies of the Government. Although we believe that POSCO E&C’s strategy of focusing on high-value-added plant construction and urban planning and development projects such as Songdo New City has enabled it to be exposed to a lesser degree to general economic conditions in Korea in comparison to some of its domestic competitors, our construction revenues have fluctuated in the past depending on the level of domestic construction activity including new construction orders. POSCO E&C’s construction operations could suffer in the future in the event of a general downturn in the construction market resulting in weaker demand, which could adversely affect POSCO E&C’s business, results of operations or financial condition.

11

Many of POSCO E&C’s domestic and overseas construction projects are on a fixed-price basis, which could result in losses for us in the event that unforeseen additional expenses arise with respect to the project.

Many of POSCO E&C’s domestic and overseas construction projects are carried out on a fixed-price basis according to a predetermined timetable, pursuant to the terms of a fixed-price contract. Under such fixed-price contracts, POSCO E&C retains all cost savings on completed contracts but is also liable for the full amount of all cost overruns and may be required to pay damages for late delivery. The pricing of fixed-price contracts is crucial to POSCO E&C’s profitability, as is its ability to quantify risks to be borne by it and to provide for contingencies in the contract accordingly.

POSCO E&C attempts to anticipate increases in costs of labor, raw materials and parts and components in its bids on fixed-price contracts. However, the costs incurred and gross profits realized on a fixed-price contract may vary from its estimates due to factors such as:

•     unanticipated variations in labor and equipment productivity over the term of a contract;

•     unanticipated increases in labor, raw material, parts and components, subcontracting and overhead costs, including as a result of bad weather;

•     delivery delays and corrective measures for poor workmanship; and

•     errors in estimates and bidding.

If unforeseen additional expenses arise over the course of a construction project, such expenses are usually borne by POSCO E&C, and its profit from the project will be correspondingly reduced or eliminated. If POSCO E&C experiences significant unforeseen additional expenses with respect to its fixed price projects, it may incur losses on such projects, which could have a material adverse effect on its financial condition and results of operations.

POSCO E&C’s domestic residential property business is highly dependent on the real estate market in Korea.

The performance of POSCO E&C’s domestic residential property business is highly dependent on the general condition of the real estate market in Korea. The construction industry in Korea is experiencing a downturn, due to excessive investment in recent years in residential property development projects, stagnation of real property prices and reduced demand for residential property, especially in areas outside of Seoul, including as a result of deteriorating conditions in the Korean economy. In addition, as liquidity and credit concerns and volatility in the global financial markets increased significantly starting in September 2008, there has been a general decline in the willingness by banks and other financial institutions in Korea to engage in project financing and other lending activities to construction companies, which may adversely impact POSCO E&C’s ability to meet its desired funding needs. The Government has taken measures to support the Korean construction industry, including easing of regulations imposed on redevelopment of apartment buildings and resale restrictions in the metropolitan areas, as well as reductions in property taxes. While the Korean real estate market has steadily recovered since the second half of 2009 and into 2010, there can be no assurance that declines in demand or prices will not take place in the Korean real estate market in the future or that a slowdown of the Korean real estate market will not have a material adverse effect on POSCO E&C’s business, results of operations or financial condition.

We are subject to environmental regulations, and our operations could expose us to substantial liabilities.

We are subject to national and local environmental laws and regulations, including increasing pressure to reduce emission of carbon dioxide relating to our manufacturing process, and our steel manufacturing and construction operations could expose us to risk of substantial liability relating to

12

environmental or health and safety issues, such as those resulting from discharge of pollutants and carbon dioxide into the environment, the handling, storage and disposal of solid or hazardous materials or wastes and the investigation and remediation of contaminated sites. We may be responsible for the investigation and remediation of environmental conditions at currently and formerly operated manufacturing or construction sites. We may also be subject to associated liabilities, including liabilities for natural resource damage, third party property damage or personal injury resulting from lawsuits brought by the government or private litigants. In the course of our operations, hazardous wastes may be generated at third party-owned or operated sites, and hazardous wastes may be disposed of or treated at third party-owned or operated disposal sites. If those sites become contaminated, we could also be held responsible for the cost of investigation and remediation of such sites, for any associated natural resource damage, and for civil or criminal fines or penalties.

Failure to protect our intellectual property rights could impair our competitiveness and harm our business and future prospects.

We believe that developing new steel manufacturing technologies that can be differentiated from those of our competitors, such as FINEX, strip casting and silicon steel manufacturing technologies, is critical to the success of our business. We take active measures to obtain protection of our intellectual property by obtaining patents and undertaking monitoring activities in our major markets. However, we cannot assure you that the measures we are taking will effectively deter competitors from improper use of our proprietary technologies. Our competitors may misappropriate our intellectual property, disputes as to ownership of intellectual property may arise and our intellectual property may otherwise become known or independently developed by our competitors. Any failure to protect our intellectual property could impair our competitiveness and harm our business and future prospects.

We rely on trade secrets and other unpatented proprietary know-how to maintain our competitive position, and unauthorized disclosure of our trade secrets or other unpatented proprietary know-how could negatively affect our business.

We rely on trade secrets and unpatented proprietary know-how and information. We enter into confidentiality agreements with each of our employees and consultants upon the commencement of an employment or consulting relationship. These agreements generally provide that all inventions, ideas, discoveries, improvements and patentable material made or conceived by the individual arising out of the employment or consulting relationship and all confidential information developed or made known to the individual during the term of the relationship is our exclusive property. We cannot assure the enforceability of these types of agreements, or that they will not be breached. We also cannot be certain that we will have adequate remedies for any breach. The disclosure of our trade secrets or other know-how as a result of such a breach could adversely affect our business.

Escalations in tension with North Korea could have an adverse effect on us and the market value of our securities.

Relations between Korea and North Korea have been tense throughout Korea’s modern history. The level of tension between the two Koreas has fluctuated and may increase abruptly as a result of current and future events. In recent years, there have been heightened security concerns stemming from North Korea’s nuclear weapons and long-range missile programs and increased uncertainty regarding North Korea’s actions and possible responses from the international community. In January 2003, North Korea renounced its obligations under the Nuclear Non-Proliferation Treaty. Since the renouncement, Korea, the United States, North Korea, China, Japan and Russia have held numerous rounds of six party multi-lateral talks in an effort to resolve issues relating to North Korea’s nuclear weapons program.

In addition to conducting test flights of long-range missiles, North Korea announced in October 2006 that it had successfully conducted a nuclear test, which increased tensions in the region and

13

elicited strong objections worldwide. In May 2009, North Korea announced that it had successfully conducted a second nuclear test and test-fired three short-rangesurface-to-air missiles. In response, the United Nations Security Council unanimously passed a resolution in June 2009 that condemned North Korea for the nuclear test and decided to expand and tighten sanctions against North Korea. In March 2010, a Korean warship was destroyed by an underwater explosion, killing many of the crewmen on board. The government formally accused North Korea of causing the sinking in May 2010, and North Korea has denied responsibility for the sinking and has threatened retaliation for any attempt to punish it for the act. On November 23, 2010, North Korean forces fired more than one hundred artillery shells targeting Yeonpyeong Island located near the maritime border between Korea and North Korea on the west coast of the Korean peninsula, killing two Korean soldiers and two civilians as well as causing substantial property damage. Korea responded by firing approximately 80 artillery shells and putting the military on its highest alert level. The Government condemned North Korea for the act and vowed stern retaliation should there be further provocation.

In addition, there recently has been increased uncertainty with respect to the future of North Korea’s political leadership and concern regarding its implications for economic and political stability in the region On September 28, 2010, Kim Jong-il, the North Korean ruler who reportedly suffered a stroke in August 2008, named Kim Jong-un, his third son who is reported to be in his twenties, as the vice chairman of the Central Military Commission and the general of the North Korean army. Although Kim Jong-il has designated his son to be his successor, the implementation of the succession plan remains uncertain. North Korea’s economy also faces severe challenges. In November 2009, the North Korean government redenominated its currency at a ratio of 100 to 1 as part of a currency reform undertaken in an attempt to control inflation and reduce income gaps. Such developments may further aggravate social and political tensions within North Korea.

Over the longer term, reunification of the two Koreas could occur. Reunification may entail a significant economic commitment by Korea. In President Lee Myung Bak’s national address on August 15, 2010, he suggested the possible adoption of a reunification tax in order to prepare for the long-term economic burden associated with reunification. Such discussions on reunification are preliminary, and it has not been decided whether or when such tax would be implemented. If a reunification tax is implemented, it may lead to a decrease in domestic consumption, which in turn may have a material adverse effect on the Korean economy. In addition, there can be no assurance that the level of tension on the Korean peninsula will not escalate in the future. Any further increase in tension, which may occur, for example, if North Korea experiences a leadership crisis, high-level contacts between Korea and North Korea break down, or military hostilities occur, could have a material adverse effect on our business, financial condition and results of operations.

If you surrender your ADRs to withdraw shares of our common stock, you may not be allowed to deposit the shares again to obtain ADRs.

Under the deposit agreement, holders of shares of our common stock may deposit those shares with the ADR depositary’s custodian in Korea and obtain ADRs, and holders of ADRs may surrender ADRs to the ADR depositary and receive shares of our common stock. However, under current Korean laws and regulations, the depositary bank is required to obtain our prior consent for the number of shares to be deposited in any given proposed deposit that exceeds the difference between (i) the aggregate number of shares deposited by us for the issuance of ADSs (including deposits in connection with the initial and all subsequent offerings of ADSs and stock dividends or other distributions related to these ADSs) and (ii) the number of shares on deposit with the depositary bank at the time of such proposed deposit. It is possible that we may not give the consent. As a result, if you surrender ADRs and withdraw shares of common stock, you may not be able to deposit the shares again to obtain ADRs. See “Item 10. Additional Information — Item 10.D. Exchange Controls.”

14

You may not be able to exercise preemptive rights for additional shares of common stock and may suffer dilution of your equity interest in us.

The Commercial Code and our articles of incorporation require us, with some exceptions, to offer shareholders the right to subscribe for new shares in proportion to their existing ownership percentage whenever new shares are issued. If we issue new shares to persons other than our shareholders (See “Item 10.B. Memorandum and Articles of Association — Preemptive Rights and Issuance of Additional Shares”), a holder of our ADSs will experience dilution of such holding. If none of these exceptions is available, we will be required to grant preemptive rights when issuing additional common shares under Korean law. Under the deposit agreement governing the ADSs, if we offer any rights to subscribe for additional shares of our common stock or any rights of any other nature, the ADR depositary, after consultation with us, may make the rights available to you or use reasonable efforts to dispose of the rights on your behalf and make the net proceeds available to you. The ADR depositary, however, is not required to make available to you any rights to purchase any additional shares unless it deems that doing so is lawful and feasible and:

•     a registration statement filed by us under the Securities Act is in effect with respect to those shares; or

•     the offering and sale of those shares is exempt from or is not subject to the registration requirements of the Securities Act.

We are under no obligation to file any registration statement under the Securities Act to enable you to exercise preemptive rights in respect of the common shares underlying the ADSs, and we cannot assure you that any registration statement would be filed or that an exemption from the registration requirement under the Securities Act would be available. Accordingly, if a registration statement is required for you to exercise preemptive rights but is not filed by us, you will not be able to exercise your preemptive rights for additional shares and may suffer dilution of your equity interest in us.

U.S. investors may have difficulty enforcing civil liabilities against us and our directors and senior management.

We are incorporated in Korea with our principal executive offices located in Seoul. The majority of our directors and senior management are residents of jurisdictions outside the United States, and the majority of our assets and the assets of such persons are located outside the United States. As a result, U.S. investors may find it difficult to effect service of process within the United States upon us or such persons or to enforce outside the United States judgments obtained against us or such persons in U.S. courts, including actions predicated upon the civil liability provisions of the U.S. federal securities laws. It may also be difficult for an investor to enforce in U.S. courts judgments obtained against us or such persons in courts in jurisdictions outside the United States, including actions predicated upon the civil liability provisions of the U.S. federal securities laws. It may also be difficult for a U.S. investor to bring an action in a Korean court predicated upon the civil liability provisions of the U.S. federal securities laws against our directors and senior management andnon-U.S. experts named in this annual report.

We could be adversely affected if the U.S. government were to determine that our affiliate’s Iran-related business activities are sanctionable under the recently expanded U.S. Iranian sanction laws and regulations.

In May 2010, we acquired a 43.1% interest in Sungjin Geotec Co., Ltd. (“Sungjin Geotec”), a manufacturer of specialized equipment used in the power and energy industries. In 2008, Sungjin Geotec entered into a EUR 100 million supply contract with Pars Oil and Gas Company (“POGC”), a subsidiary of National Iranian Oil Company, to supply equipment for projects used to develop natural gas fields located in South Pars, Iran. Sungjin Geotec recognized revenues of approximately

15

Won 8.6 billion in 2008, Won 83.5 billion in 2009 and Won 61.0 billion in 2010 from such activities, and it expects that its contract with POGC will be completed by the end of 2011.

In July 2010, the United States adopted legislation that expands U.S. economic sanctions against foreign companies doing business with Iran in certain sectors. The Comprehensive Iran Sanctions, Accountability, and Divestment Act of 2010 (the “CISADA”) expands the scope of sanctionable activities by, among other things, broadening the definition of “investment” under the Iran Sanctions Act (the “ISA”) arguably to include the supply of goods for use in petroleum and gas production. The CISADA also expands the severity of potential sanctions available under the ISA and imposes mandatory investigation and reporting requirements designed to increase the likelihood of enforcement. The CISADA requires the imposition of sanctions against parties found by the U.S. administration, following an investigation, to have engaged in conduct sanctionable under the ISA, subject to certain waiver provisions and exceptions.

Under the ISA, as amended, sanctions can also be imposed against a company that has actual knowledge of, or should have known of, sanctionable conduct engaged in by another company that it owns or controls. A range of sanctions may be imposed on companies that engage in sanctionable activities, including among other things the blocking of any property subject to U.S. jurisdiction in which the sanctioned company has an interest, which could include a prohibition on transactions or dealings involving securities of the sanctioned company. By its terms, the CISADA is applicable to certain investments in Iran that commenced on or after July 1, 2010, and it is not clear whether a supply of equipment after that date pursuant to a legally binding contractual obligation that arose prior to July 1, 2010 would or would not be determined to be sanctionable under the CISADA.

Sungjin Geotec’s supply contract with POGCand/or performance thereunder may be sanctionable under the CISADA if the CISADA’s revised definition of “investment” is interpreted to cover the supply of goods to parties developing gas fields in Iran and if future performance under the supply contract is not considered to have “commenced” prior to the enactment of the CISADA. Accordingly, there can be no assurance that Sungjin Geotec’s Iran-related business activities do not constitute sanctionable activities or that we will not be subjected to sanctions under the ISA as amended by the CISADA. Our business and reputation could be adversely affected if the U.S. government were to determine that Sungjin Geotec’s Iran-related business activities constitute sanctionable activity attributable to us. Investors in our securities may also be adversely affected if we are sanctioned under the CISADA or if their investment in the securities is restricted under any sanctions regimes with which the investors are required to comply. As noted above, sanctions under the ISA could include the blocking of any property in which we have an interest, which would effectively prohibit all U.S. persons from receiving any payments from us, or otherwise acquiring, holding, withholding, using, transferring, withdrawing, transporting, importing, or exporting any property in which we have any interest.

We expect to continue operations and investments relating to countries targeted by United States and European Union economic sanctions.

The U.S. Department of the Treasury’s Office of Foreign Assets Control, or “OFAC,” enforces certain laws and regulations (“OFAC Sanctions”) 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, governments, entities and individuals that are the subject of OFAC Sanctions (“U.S. Sanctions Targets”). U.S. persons are also generally strictly prohibited from facilitating such activities or transactions. Similarly, the European Union enforces certain laws and regulations (“E.U. Sanctions”) that impose restrictions upon nationals of E.U. member states, persons located within E.U. member states, entities incorporated or constituted under the law of an E.U. member state, or business conducted in whole or in part in E.U. member states with respect to activities or transactions with certain countries, governments, entities and individuals that are the subject of E.U. Sanctions (“E.U. Sanctions Targets” and together with U.S. Sanctions Targets, “Sanctions Targets”). E.U. persons are also generally prohibited from activities that promote such activities or transactions.

16

We engage in limited business activities and investments relating to Iran and Myanmar. We also hold a 70.0% interest in Myanmar-POSCO Steel Co., Ltd., an entity that is an E.U. Sanctions Target under Council Regulation (EC) No. 194/2008, as amended. Such activities and investments do not involve any U.S. goods or services, and we do not export or reexport U.S. goods or services directly or indirectly to any Sanctions Target. For each of 2008, 2009 and 2010, our activities and investments relating to Sanctions Targets accounted for less than 1.0% of our total consolidated revenues and total consolidated assets, respectively.

On September 20, 2010, we acquired a 68.15% interest in Daewoo International for Won 3.37 trillion. Daewoo International is a global trading company that primarily engages in the trading of steel and raw materials, including with certain Sanctions Targets, as well as investing in energy development projects. Daewoo International generated approximately 7% of its revenues in 2010 from its trading activities with Iranian entities. Daewoo International also has a portfolio of investments in energy exploration and production projects, including a gas field exploration project in Myanmar, in which Daewoo International has invested Won 653 billion since 1998 and plans to make substantial further investments in the future. This project is not expected to generate any revenues until 2013. On a consolidated basis under Korean GAAP, Daewoo International generated revenues of Won 16,112 billion in 2010 and had total assets of Won 5,652 billion as of December 31, 2010.

We expect to continue to engage in business activities and make investments in Sanctions Targets over the foreseeable future. Although we believe that OFAC Sanctions under their current terms are not applicable to our activities, our reputation may be adversely affected, some of our U.S. investors may be required to divest their investments in us under the laws of certain U.S. states or under internal investment policies or may decide for reputational reasons to divest such investments, and some U.S. institutional investors may forego the purchase of our Notes. We are aware of initiatives by U.S. governmental entities and U.S. institutional investors, such as pension funds, to adopt or consider adopting laws, regulations, or policies prohibiting transactions with or investment in, or requiring divestment from, entities doing business with countries identified as state sponsors of terrorism. We cannot assure you that the foregoing will not occur or that such occurrence will not have a material adverse effect on the value of our securities.

Korean GAAP differs in significant respects from accounting standards applicable in certain other countries, including U.S. GAAP and the International Financial Reporting Standards.

Our financial statements included in this offering circular are prepared in accordance with Korean GAAP and reconciled to U.S. GAAP. Korean GAAP differs in significant respects from accounting standards applicable in certain other countries, including U.S. GAAP. See “Item 5. Operating and Financial Review and Prospects — Item 5.B. Liquidity and Capital Resources — U.S. GAAP Reconciliation” and “— Recent Accounting Pronouncements in U.S. GAAP” and Note 32 of Notes to Consolidated Financial Statements.

In March 2007, the Financial Services Commission and the Korea Accounting Institute announced a road map for the adoption of Korean IFRS, pursuant to which all listed companies in Korea, including us, will be required to prepare their annual financial statements beginning in 2011 that differ in certain respects from IFRS applied in other countries.

In preparation of such adoption, we began preparing our internal financial statements under both Korean GAAP and Korean IFRS starting in January 2010. Beginning in 2011, we have discontinued reporting under Korean GAAP with reconciliation to U.S. GAAP and instead have commenced reporting under Korean IFRS and we also plan to release annual financial statements prepared pursuant to IFRS as issued by the International Accounting Standards Board, or IASB. Although our accounting department is currently analyzing the effects of adopting IFRS on our annual financial statements, it is not possible to estimate with any degree of certainty the exact impact on our annual financial statements from such adoption because the IFRS accounting policies to be adopted

17

by us for such financial statements have not been finalized. Accordingly, there can be no assurance that the adoption of IFRS will not adversely affect our reporting results of operations or financial condition.

We had total assets of Won 67,946 billion and total shareholders’ equity of Won 37,201 billion as of December 31, 2010, compared to total assets of Won 50,312 billion and total shareholders’ equity of Won 31,664 billion as of December 31, 2009.

Business Strategy

Leveraging on our success during the past four decades, our goal is to strengthen our position as one of the leading steel producers in the world and strive to rank among the top three global steel companies in technology leadership, operational excellence and production capacity. In recent years, the global steel industry has undergone significant consolidation, resulting in the emergence of steel companies with expanded production capacity. We seek to achieve continued global excellence in this era of consolidation through a renewed emphasis on growth and innovation. Over the next decade, we seek to expand our position as a global company by adding significant production bases outside Korea. We also intend to secure growth by further solidifying our market position in the steel sector, while allocating additional resources into businesses that we believe will offer us greater potential returns and serve as our new growth engines, such as the engineering and construction, energy and information and technology businesses.

We seek to strengthen our competitiveness and pursue growth through the following core business strategies:

Continue to Seek Growth Opportunities in the Steel Sector

We carefully seek out promising investment opportunities abroad, primarily in China, India, Southeast Asia and Mexico, in part to prepare for the eventual maturation of the Korean steel market. We believe that China, India, Southeast Asia and Mexico will continue to offer substantial growth opportunities, and we plan to selectively seek investment opportunities and expand our production base in these countries.

19

For example, we obtained the approval of the Government of India in May 2011 to construct an integrated steel mill in Orissa State, and we are currently in the process of acquiring the land on which the plant will be constructed. With respect to development of iron ore mines in Orissa State, we are waiting for the final judgment from the Indian Supreme Court on mining rights. In June 2010, we also signed a memorandum of understanding with the Government of Karnataka, a state in southwest India, to construct an integrated steel mill in Karnataka, and we are in discussions with the Government of Karnataka to obtain a mining lease and secure land with appropriate infrastructure. In Vietnam, we completed the construction of plant in September 2009 with an annual production capacity of 1.2 million tons of cold rolled products and commenced commercial production in October 2009. In Mexico, we completed the construction of a plant in August 2009 with an annual production capacity of 0.4 million tons of cold rolled products and commenced commercial production in June 2009 to produce automotive steel sheets to supply automotive manufacturers in Mexico, Southeastern United States and South America. In Indonesia, we entered into a joint venture agreement with PT Krakatau Steel, a government-owned steel company in Indonesia, in August 2010 to construct a steel mill with an annual capacity of 6.0 million tons. The steel mill is expected to commence commercial production with an initial annual capacity of 3 million tons upon completion of the first phase of construction in 2013.

We are also building a global distribution network of supply chain management centers to provide processing and logistics services and more effectively respond to changes in consumer trends in the global steel market. In 2010, we operated 48 supply chain management centers worldwide that recorded aggregate sales of 3.6 million tons of steel products. We plan to continue expanding our global network of supply chain management centers. In Korea, we plan to continue to expand our production facilities and upgrade our facilities that utilize advanced manufacturing technologies, and we plan to enhance the quality of our products through continued modernization and rationalization of our facilities.

Maintain Technology Leadership

As part of our strategy, we have identified core products that we plan to further develop, such as premium automotive steel sheets, silicon steel and API-grade steel, and we will continue to invest in developing innovative products that offer the greatest potential returns and enhance the overall quality of our products. In order to increase our competitiveness, we plan to make additional investments in the development of new manufacturing technologies, such as FINEX, strip casting, endless rolling and environment-friendly manufacturing processes. We will continue to refine FINEX, a low cost, environmentally friendly steel manufacturing process that optimizes our production capacity by utilizing non-agglomerated iron ore fines and using non-coking coal as an energy source and a reducing agent. We believe that FINEX offers considerable environmental and economic advantages through elimination of major sources of pollution such as sintering and coking plants, as well as reducing operating and raw material costs. We also plan to accelerate development of other advanced technologies, such as strip casting that directly casts coils from liquid steel and a rolling process that rolls hot rolled coils up to 40 slabs at a time. We plan to further devote additional resources to our research and development efforts and increase the proportion of our sales of higher margin, higher value-added products.

Pursue Cost-Cutting through Operational and Process Innovations

We seek to achieve cost reductions in this era of increasing raw material costs through our companywide process for innovation and enhancing efficiency of operations. We believe that strategic cost cutting measures through utilization of efficient production methods and management discipline will strengthen our corporate competitiveness. After implementation of Six Sigma innovations in recent years, we are now implementing the Quick Six Sigma program, a customized program that we believe will enhance our corporate culture that rewards innovative ideas at all stages of our operations and enable us to benchmark successful innovations to all relevant processes within the company. We will

20

also strive to invest more in human resources development to nurture employees who are capable of working in the global environment.

Secure Procurement of Raw Materials through Strategic Investments

We purchase substantially all of the principal raw materials we use, including iron ore, coal and nickel, from sources outside Korea. Import prices of many of the principal raw materials, including iron ore and nickel, have fluctuated substantially in recent years. To secure adequate procurement of principal raw materials, we have invested and will continue to explore additional investment opportunities in various raw material development projects abroad, as well as enter into long-term contracts with leading suppliers of raw materials, principally in Australia and Brazil.

Selectively Seek Opportunities in Growth Industries

We will continue to selectively seek opportunities in growth industries to diversify our business both vertically and horizontally. New businesses not related to our steel operations in which we intend to focus our diversification include power generation, alternative energy development and information and technology.

POSCO Power Corporation, our consolidated subsidiary in which we hold an 85.7% interest, is the largest private power generation company in Korea. Through POSCO ICT Co., Ltd., a72.5%-owned subsidiary, we also engage in information and technology consulting services as well as automation and system integration engineering services. POSCO E&C, our consolidated subsidiary in which we hold an 89.5% interest, is one of the leading engineering and construction companies in Korea that primarily engages in the planning, design and construction of industrial plants and architectural works and civil engineering. On September 20, 2010, we acquired a 68.15% interest in Daewoo International for Won 3.37 trillion. Daewoo International is a global trading company that primarily engages in trading of steel and raw materials as well as investing in energy development projects. We will continue to selectively seek opportunities to indentify new growth engines and diversify our operations. On March 4, 2011, we submitted a letter of intent to Asiana Airlines Inc. and Daewoo E&C Co., Ltd. for the acquisition of a controlling stake in Korea Express Co., Ltd., a leading logistics company in Korea. Korea Express is being sold in an auction process and the preferred bidder is expected to be selected in the second quarter of 2011.

We will continue to selectively seek opportunities to identify new growth engines and diversify our operations.

Our domestic sales volume increased from 21.0 million tons in 2006 to 22.9 million tons in 2008, reflecting a general increase in demand from our domestic customers. In 2009, our domestic sales volume decreased to 19.4 million tons principally due to the weak demand for steel products in certain key industries such as the automotive and construction industries. In 2010, our domestic sales volume rebounded to 21.8 million tons due to an increase in demand from the automotive industry and the household goods industry, the impact of which was partially offset by a decrease in demand from the construction industry. Our market share decreased from 42.3% in 2006 to 38.6% in 2007 before rebounding to 39.1% in 2008. Our market share further increased to 42.8% in 2009 but decreased to 41.6% in 2010.

Domestic sales volume of other Korean steel companies, such as Hyundai Steel Co., Ltd. and Dongbu Steel Co., Ltd., increased from 18.1 million tons in 2006 to 21.2 million tons in 2007 primarily due to an increase in their production capacity, and the aggregate market share of other Korean steel companies increased from 36.4% in 2006 to 38.5% in 2007. In 2008, in part due to our decision to sell a greater portion of our sales volume to consumers in Korea due to more favorable domestic prices, domestic sales volume of other Korean steel producers decreased to 20.7 million tons and their aggregate market share decreased to 35.3%. In 2009, domestic sales volume of other Korean steel producers further decreased to 16.9 million tons in 2009 as the general demand for steel products decreased in response to the economic downturn in Korea in the first half of 2009. In 2010, domestic sales volume of other Korean steel producers rebounded to 19.2 million tons primarily due to a general recovery of the Korean economy.

In recent years, domestic consumers of steel products have also relied on imports from foreign competitors, primarily from China, Japan and Russia. Import volume of steel products steadily increased from 10.6 million tons in 2006 to 15.0 million tons in 2008, resulting in an increase in their aggregate domestic market share from 21.3% in 2006 to 25.6% in 2008. However, due to the global economic downturn, import volume of steel products decreased significantly to 9.0 million tons of steel products in 2009, resulting in a decrease in market share to 19.9%. Imports from foreign competitors showed strong growth in 2010 as import sales volume rebounded to 11.3 million tons.

We sell in Korea higher value-added and other finished products to end-users and semi-finished products to other steel manufacturers for further processing. Local distribution companies and sales affiliates sell finished steel products to low-volume customers. We provide service technicians for large customers and distributors in each important product area.

Exports

Our export sales and overseas sales to customers abroad represented 43.6% of our total sales volume of steel products in 2010, 61.9% of which was generated from exports sales and overseas sales to customers in Asian countries. Our export sales and overseas sales to customers abroad in terms of sales volume increased by 45.0% to 16.8 million tons in 2010 compared to 2009, reflecting general improvement of the global economy and increase in demand for our products from customers abroad. The tables below set out our export sales and overseas sales to customers abroad in terms of sales volume of steel products by geographical market and by product for the periods indicated.

Recent difficulties affecting the U.S. and global financial sectors, adverse conditions and volatility in the U.S. and worldwide credit and financial markets, fluctuations in oil and commodity prices and the general weakness of the U.S. and global economies have increased the uncertainty of global economic prospects in general and have adversely affected the global and Korean economies. Such developments weakened global demand in steel consumption in 2008 and 2009. The World Steel Association forecasts that global apparent crude steel use is expected to increase by 5.6% to 1,466 million metric tons in 2011 after increasing by 13.9% in 2010.

In recent years, driven in part by strong growth in steel consumption in China, the global steel industry has experienced renewed interest in expansion of steel production capacity. World Steel Dynamics estimated the global crude steel production capacity to be 1,638 million tons in 2010. The increased production capacity, combined with weakening demand due primarily to the recent slowdown of the global economy, has resulted in production over-capacity in the global steel industry. Production over-capacity in the global steel industry may intensify if the slowdown of the global economy occurs or demand from developing countries that have experienced significant growth in the past several years does not meet the recent growth in production capacity.

We distribute our export products mostly through Korean trading companies, including Daewoo International, and our overseas sales subsidiaries. Our largest export market in 2010 was Asian countries other than China and Japan, which accounted for 26.6% of our export volume of steel products, including sales by our overseas subsidiaries. The principal products exported to Asian countries other than China and Japan were cold rolled products and hot rolled products. Sales volume to Asian countries other than China and Japan increased by 5.0% from 2.3 million tons in 2008 to 2.4 million tons in 2009 primarily due to our decision to export more to such countries because of relatively more stable market conditions of the Southeast Asian region compared to China and Japan. Our exports to Asian countries other than China and Japan increased by 82.6% to 4.5 million tons in 2010 primarily due to the inclusion of export trading activities of Daewoo International in such region in 2010 as well as a general recovery of the automotive industry in Thailand and an increase in our supply of hot rolled products to POSCO-Vietnam Co., Ltd.

Our exports to China amounted to 2.6 million tons in 2008, 3.9 million tons in 2009 and 4.1 million tons in 2010. Our exports to China increased by 54.0% in 2009 primarily due to a strong increase in demand from Chinese customers. The increase in our exports to China slowed to 4.3% in 2010 primarily due to adjustment of our export sales mix to Asian countries in response to the recovery of demand from Asian countries other than China and Japan. Sales volume to Japan decreased by 8.6% to 2.0 million tons in 2008 and further decreased by 35.2% to 1.3 million tons in 2009 as we elected to focus our sales efforts in China and other markets with greater growth opportunities. Sales volume to Japan rebounded by 46.3% to 1.8 million tons in 2010 primarily due to a general recovery of the Japanese automotive industry.

Our exports to North America and Europe remained stable at 1.3 million tons in 2008 and 1.2 million tons in 2009. Our exports to North America increased by 151.9% to 1.9 million tons in 2010 primarily due to a general recovery of the U.S. automotive industry, while our exports to Europe increased by 101.1% to 0.9 million tons in 2010 primarily due to a general recovery of the European automotive industry as well as our procurement of a new customer for our stainless steel products. A significant part of our sales in North America are made to USS-POSCO Industries (“UPI”), a50-50 joint venture between U.S. Steel Corporation and us. We sell hot rolled products to UPI, which uses

27

such products to manufacture cold rolled and galvanized steel products and tin-plate products for sale in the United States. Our sales to UPI were 519 thousand tons in 2008, 325 thousand tons in 2009 and 398 thousand tons in 2010.

Anti-Dumping and Countervailing Proceedings

In the United States, a number of our products have been subject to anti-dumping and countervailing proceedings since 1992. As a result of these proceedings, our sales of corrosion resistant steel are subject to a countervailing duty margin of 0.10% and an anti-dumping duty margin of 0.05% (which is effectively zero pursuant to the de minimis margin rule). Our sales of stainless steel plates in coils are subject to an anti-dumping duty of 1.19% and our sales of stainless steel sheets and strips in coils are subject to an anti-dumping duty of 0.92%.

In China, we were subject to an anti-dumping duty of 11% on our sales of stainless cold rolled steel from December 2000 to April 2011. During such period, we agreed to certain price undertakings and exported certain types of stainless cold rolled steel products to China that were exempt from such anti-dumping duty. On April 7, 2011, China withdrew the anti-dumping duties imposed on stainless cold rolled steel products imported from Korea.

In India, our sales of stainless cold rolled steel have been subject to an anti-dumping duty ranging from $62.61 per ton to $234.98 per ton starting in November 2009 for a five-year period. In Russia, our sales of stainless steel have been subject to an anti-dumping duty of 4.8% starting in November 2010 for a three-year period. Recently, several countries have initiated anti-dumping investigations and other safeguard proceedings relating to our global sales operations, including initiation of anti-dumping investigations by the Brazilian government on our sales of plates in August 2010 and coated steel in April 2011. We are also subject to anti-dumping proceedings in Thailand but we were not assessed any dumping margin rate in the latest round of assessment completed in July 2010.

Pricing Policy

We determine the sales price of our products based on market conditions. In setting prices, we take into account our costs, including those of raw materials, supply and demand in the Korean market, exchange rates, and conditions in the international steel market.

Our export prices can fluctuate considerably over time, depending on market conditions and other factors. The export prices of our higher value-added steel products in the largest markets are determined considering the prices of similar products charged by our competitors. Our export prices in Dollar terms increased in 2008 due to strong overseas demand, particularly from China and Japan, and increase in prices of raw materials such as iron ore and coal. However, we reduced our export prices in late 2008 in response to the intensification of the global financial crisis and continued to reduce our export prices in the first half of 2009. Starting in the third quarter of 2009, our export prices gradually started to recover due to an increase in demand driven by improvement in business confidence and higher level of economic activities as well as a decrease in our inventory level. This trend continued in the first half of 2010, but we maintained similar pricing levels in the second half of 2010. We may decide to adjust our future sales prices on an on-going basis subject to market demand for our products, prices of raw materials, the production outlook of the global steel industry and global economic conditions in general.

Raw Materials

Steel Production

The principal raw materials used in producing steel through the basic oxygen steelmaking method are iron ore and coal. We import all of the coal and virtually all of the iron ore that we use. In 2010, POSCO imported approximately 49.3 million dry metric tons of iron ore and 26.2 million wet

28

metric tons of coal. Iron ore is imported primarily from Australia, Brazil and South Africa. Coal is imported primarily from Australia, Canada and China. In 2010, we purchased most of our iron ore and coal imports pursuant to long-term contracts. The long-term contracts generally have terms of three to ten years and provide for periodic price adjustments to the then-market prices. The long-term contracts to purchase iron ore and coal generally provide for quarterly adjustments to the purchase prices to be determined through negotiation between the supplier and us. Such price negotiations are driven by various factors, including the global economic outlook, global market prices of raw materials and steel products, supply and demand outlook of raw materials and production costs of raw materials. Typically, globally influenced buyers and sellers of raw materials determine benchmark prices of raw materials, based on which other buyers and sellers negotiate their prices after taking into consideration the quality of raw materials and other factors. We typically have an option to increase or decrease the fixed purchase amounts up to 5% or 10% each year. We or the suppliers may cancel the long-term contracts only if performance under the contracts is prevented by causes beyond our or their control and these causes continue for a specified period.

We also make investments in exploration and production projects abroad to enhance our ability to meet the requirements for high-quality raw materials, either as part of a consortium or through acquisition of a minority interest. We purchased approximately 23.1% of our iron ore and coal imports in 2010 from foreign mines in which we have made investments. Our major investments to procure supplies of coal include an investment of A$424 million in July 2008 to acquire a 10% interest in Macarthur Coal Ltd. to secure approximately 1.0 million tons of coal per year. In May 2010, we also acquired a 7.8% interest in Minas de Revuboe in Mozambique, which expects to supply 430 thousand tons of coal per year when it is in full operation starting in 2014, for US$18.9 million. In addition, in July 2010, we acquired a 70% interest in Hume Coal in Australia for A$50.2 million. We expect Hume Coal, which is currently at an exploration stage, to supply 1.3 million tons of coal per year starting in 2015.

Our major investments to procure supplies of iron ore include an investment of US$500 million in December 2008 to acquire a 6.5% interest in Nacional Minérios S.A., an iron ore mining company in Brazil, in a consortium with Japanese steel manufacturers and trading companies. In 2009, we started importing iron ore from the Brazilian venture and we expect to secure approximately 5.0 million tons annually by 2012. We also made an initial investment of A$248 million in January 2010 to acquire a 3.75% interest in Roy Hill Holdings Pty., Ltd. We plan to increase our total shareholding interest up to 15% to secure approximately 8.5 million tons of iron ore per year. In July 2010, we acquired a 24.5% interest in the API iron ore joint venture in Pilbara, Australia for A$184 million, which expects to supply 9.8 million tons of iron ore starting in 2014. We will continue to seek opportunities to enter into additional strategic relationships that would enhance our ability to meet the requirements for principal raw materials.

The average market price of coal per wet metric ton (benchmark free on board price of Australian premium hard coking coal) was US$250 in 2008, US$172 in 2009 and US$191 in 2010. The average market price of iron ore per dry metric ton (free on board price of Platts Iron Ore index with iron (Fe) 62% content) was US$126 in 2008, US$68 in 2009 and US$136 in 2010. We currently do not depend on any single country or supplier for our coal or iron ore.

Stainless Steel Production

The principal raw materials for the production of stainless steel are wrought nickel, ferrochrome, stainless steel scrap and carbon steel scrap. We purchase a substantial portion of our requirements for wrought nickel from leading producers in Australia, Indonesia, New Caledonia and Japan, as well as Korea. A substantial portion of the requirements for ferrochrome are purchased from producers in South Africa, India and Kazakhstan. Most of the requirements for stainless steel scrap are sourced from domestic and overseas suppliers in Japan, United States, European Union and Southeast Asian countries. As for the requirements for carbon steel scrap, scrap from the Pohang Steelworks is also utilized. The average market price of nickel per ton trading on the London Metal

29

Exchange decreased from US$21,111 in 2008 to US$14,655 in 2009 but rebounded to US$21,809 in 2010.

In order to secure stable sources of nickel for stainless steel production, we entered into a joint venture in May 2006 with Société Minière du Sud Pacifique S.A. to establish SNNC Co., Ltd. (“SNNC”) a company primarily engaged in nickel smelting. We hold a 49% interest in SNNC and Société Minière du Sud Pacifique S.A., a major mining company based in New Caledonia, holds the remaining 51% interest. SNNC operates a nickel smelting works with a production capacity of 30 thousand tons of nickel per year.

Transportation

Since 1983, we have retained a fleet of dedicated bulk carriers to transport our raw materials through long-term contracts with shipping companies in Korea. These dedicated bulk carriers transported approximately 71% of our coal and iron ore in 2010, with the remaining 29% transported by other vessels through chartering contracts. All imported raw materials are unloaded at our port facilities in Pohang and Gwangyang. Costs of transportation of iron ore and coal represented approximately 11% and 8%, respectively, of the total cost of such materials in 2010.

The Steelmaking Process

Our major production facilities, Pohang Works and Gwangyang Works, produce steel by the basic oxygen steelmaking method. The stainless steel plant at Pohang Works produces stainless steel by the electric arc furnace method. Continuous casting improves product quality by imparting a homogenous structure to the steel. Pohang Works and Gwangyang Works produce all of their products through continuous casting.

Steel — Basic Oxygen Steelmaking Method

First, molten pig iron is produced in a blast furnace from iron ore, which is the basic raw material used in steelmaking. Molten pig iron is then refined into molten steel in converters by blowing pure oxygen at high pressure to remove impurities. Different desired steel properties may also be obtained by regulating the chemical contents.

At this point, molten steel is made into semi-finished products such as slab, blooms or billets at the continuous casting machine. Slab, blooms and billets are produced at different standardized sizes and shapes. Slab, blooms and billets are semi-finished lower margin products that we either use to produce our further processed products or sell to other steelmakers that produce further processed steel products.

Slab are processed to produce hot rolled coil products at hot strip mills or to produce plates at plate mills. Hot rolled coils are an intermediate stage product that may either be sold to our customers as various finished products or be further processed by us or our customers into higher value-added products, such as cold rolled sheets and silicon steel sheets. Blooms and billets are processed into wire rods at wire rod mills.

Stainless Steel — Electric Arc Furnace Method

Stainless steel is produced from stainless steel scrap, chrome, nickel and steel scrap using an electric arc furnace. Stainless steel is then processed into higher value-added products by methods similar to those used for steel production. Stainless steel slab are produced at a continuous casting mill. The slab are processed at hot rolling mills into stainless steel hot coil, which can be further processed at cold strip mills to produce stainless cold rolled steel products.

30

Competition

Domestic Market

We are the largest fully integrated steel producer in Korea. We generally face fragmented competition in the domestic market. In hot rolled products, where we had a market share of approximately 40% in 2010, we face competition from a Korean steel producer that operatesmini-mills and produces hot rolled coil products from slabs and from various foreign producers, primarily from China and Japan. In cold rolled products and stainless steel products, where we had a market share of approximately 55% and 60%, respectively, in 2010, we compete with smaller specialized domestic manufacturers and various foreign producers, primarily from China and Japan. For a discussion of domestic market shares, see “— Markets — Domestic Market.”

We may face increased competition in the future from new specialized or integrated domestic manufacturers of steel products in the Korean market. Our biggest competitors in Korea are Hyundai Steel Co., Ltd. with an annual crude steel production of approximately 12.0 million tons and Dongbu Steel Co., Ltd. with an annual crude steel production of approximately 4.6 million tons. Hyundai Steel Co., Ltd. completed construction of an integrated steel mill with an annual capacity of 4 million tons in January 2010 and added a second furnace with the same capacity in November 2010.

The Korean Government does not impose quotas on or provide subsidies to local steel producers. As a World Trade Organization signatory, Korea has also removed all steel tariffs.

Export Markets

The competitors in our export markets include all the leading steel manufacturers of the world. In recent years, there has been a trend toward industry consolidation among our competitors, and smaller competitors in the global steel market today may become larger competitors in the future. For example, Mittal Steel’s takeover of Arcelor in 2006 created a company with approximately 10% of global steel production capacity. Competition from global steel manufacturers with expanded production capacity such as ArcelorMittal, and new market entrants, especially from China and India, could result in a significant increase in competition. Major competitive factors include range of products offered, quality, price, delivery performance and customer service. Our larger competitors may use their resources, which may be greater than ours, against us in a variety of ways, including by making additional acquisitions, investing more aggressively in product development and capacity and displacing demand for our export products.

Various export markets currently impose tariffs on different types of steel products. However, we do not believe that tariffs significantly affect our ability to compete in these markets.

Subsidiaries and Global Joint Ventures

Steel Production

In order to effectively implement our strategic initiatives and to solidify our leadership position in the global steel industry, we have established various subsidiaries and global joint ventures around the world.

We established POSCO Specialty Steel Co., Ltd. as a wholly-owned subsidiary in Korea in February 1997. POSCO Specialty Steel produces high-quality steel products for the automotive, machinery, nuclear power plant, shipbuilding, aeronautics and electronics industries. Production facilities operated by POSCO Specialty Steel have an aggregate annual production capacity of 840 thousand tons of wire rods, round bars, steel pipes and semi-finished products. POSCO Specialty Steel Co., Ltd. produced 728 thousand tons of such products in 2010.

In order to expand our sale of value-added products, we established POSCO Coated and Color Sheet Co., Ltd. by merging a coated steel manufacturer and a color sheet manufacturer in March 1999. POSCO Coated and Color Sheet produces 600 thousand tons a year of both galvanized and

31

aluminized steel sheets widely used in the construction, automotive parts and home appliances industries. POSCO Coated and Color Sheet also produces color sheets with an annual capacity of 350 thousand tons that are mainly used for interior and exterior materials and home appliances.

We entered into an agreement with Sagang Group Co. to establish Zhangjiagang Pohang Stainless Steel Co., Ltd., a joint venture company in China for the manufacture and sale of stainless cold rolled steel products. We have an 82.5% interest in the joint venture (including 23.9% interest held by POSCO China Holding Corporation). The plant commenced production of stainless cold rolled steel products in December 1998. The joint venture also completed the construction of new mills in July 2006 with additional annual production capacity of approximately 800 thousand tons of stainless hot rolled products. Zhangjiagang Pohang Stainless Steel produced 831 thousand tons of stainless steel products in 2010.

We established Qingdao Pohang Stainless Steel Co., Ltd., a wholly owned subsidiary set up to manufacture and sell stainless cold rolled steel products in China. Construction of the plant operated by Qingdao Pohang Steel began in April 2003 and became operational in December 2004, with an annual production capacity of 180 thousand tons of stainless cold rolled steel products. Qingdao Pohang Steel produced 188 thousand tons of such products in 2010.

In August 2003, we entered into a joint venture agreement with Benxi Iron and Steel Group in China to establish Benxi Steel POSCO Cold Rolled Sheet Co., Ltd. and build a cold rolling mill with annual production capacity of 1.9 million tons. The cold rolling mill became operational in March 2006 and produced 1.7 million tons of such products in 2010. We currently hold a 25% interest in this joint venture.

In November 2003, we launched POSCO China Holding Corporation, a wholly-owned holding company for our investments in China. POSCO China Holding Corporation also provides support to our Chinese investment projects and affiliated companies with their marketing efforts in China and solidifies their business relationships with clients and suppliers.

In addition to the above investments, we are carefully seeking out additional promising investment opportunities abroad. In June 2005, we entered into a memorandum of understanding with Orissa State Government of India for the construction of an integrated steel mill and the development of iron ore mines in Orissa State. We estimate the aggregate costs of the initial phase of construction and mine development to be approximately $3.7 billion and an additional cost of approximately $8.3 billion in order to increase the annual production capacity to 12 million tons of plates and hot rolled products. In 2008, we obtained stage one clearance for 2,959 acres of forest land from the Indian Supreme Court, and acquired approximately 500 acres of land for the construction of a steel mill and a port. In the process of acquiring land for construction, we have provided rehabilitation and resettlement packages (including construction of 60 transit homes) for local residents affected by our project. On May 2, 2011, we obtained the final forest clearance from the Ministry of Environment in India. Currently, we are in the process of acquiring approximately 4,000 acres of land for the construction. We are also waiting for the judgment from the Indian Supreme Court on mining rights for the development of iron ore mines in Orissa State.

We entered into an agreement with Nippon Steel Corporation to establish POSCO Vietnam Co., Ltd., a joint venture company in Vietnam for the manufacture and sale of cold rolled steel products. We have an 85% interest in the joint venture. We completed the construction of a plant in September 2009 with an annual production capacity of 1.2 million tons of cold rolled products and commenced commercial production. POSCO Vietnam produced 966 thousand tons of such products in 2010.

In Mexico, we completed the construction of a plant in August 2009 with an annual production capacity of 0.4 million tons of cold rolled products and commenced commercial production to supply automotive manufacturers in Mexico, Southeastern United States and South America.

32

In the United States, we entered into a joint venture in March 2007 with US Steel and SeAH to establish United Spiral Pipe LLC to produce American Petroleum Institute-compliant pipes (“API Pipes”) and non-API pipes. We hold a 35% interest in the company. US Steel and we each supply 50% of the hot rolled steel required for the production of pipes. In response to weak demand for the API Pipes in recent years, United Spiral Pipe is currently producing non-API Pipes that are used for general construction piling purposes. United Spiral Pipe started commercial production in May 2010 and produced 18 thousand tons of such products in 2010.

In order to secure an alternative sales source for stainless hot rolled steel products and an export base for expanding into the Southeast Asia stainless steel markets, we acquired a 15% interest in Thainox Stainless Public Company Limited, a major stainless steel manufacturer in Thailand, in 2007.

We have also established supply chain management centers around the world to provide processing and logistics services such as cutting flat steel products to smaller sizes to meet customers’ needs. In 2010, our 48 supply chain management centers recorded aggregate sales of 3.5 million tons of steel products.

Steel Trading

Our trading activities consist of exporting and importing a wide range of steel products that are both obtained from and supplied to POSCO, as well as between other suppliers and purchasers in Korea and overseas. To strengthen our global market presence, we are coordinating these trading activities through a global trading network comprised of overseas subsidiaries, branches and representative offices. Such subsidiaries and offices support our trading activities by locating suitable local suppliers and purchasers on behalf of ourselves as well as customers, identifying business opportunities and providing information regarding local market conditions. Our consolidated subsidiaries engaged in steel trading include POSCO Processing & Service Co., Ltd. that primarily focuses in the domestic market, and POSCO Asia Company Limited located in Hong Kong, POSCO Japan Co., Ltd. located in Tokyo, Japan and POSCO America Corporation located in New Jersey, U.S.A.

On September 20, 2010, we acquired a 68.15% interest in Daewoo International for Won 3.37 trillion. Daewoo International is a global trading company that primarily engages in trading of steel and raw materials as well as investing in energy and mineral development projects. It also manufactures and sells textiles, operates a department store in Korea, and holds a 24% interest in Kyobo Life Insurance, Korea’s third largest life insurance company in terms of market share in 2010. Daewoo International was established in December 2000 when the international trading and construction businesses of Daewoo Corporation were spun off into three separate companies as part of a debt workout program of Daewoo Corporation.

Daewoo International’s trading activities consist of exporting and importing a wide variety of products and commodities, including iron and steel, chemicals, natural resources and energy, automotive parts, machinery and plant equipment, electronics products, raw materials for steel production, non-ferrous metals, agricultural commodities, livestock and textiles. Daewoo International is also engaged in third-country trade, which does not involve exports from or imports to Korea. In the past three years, export sales represented more than 50%, third-country trade represented approximately 40% and import sales represented less than 10% of Daewoo International’s total sales on a consolidated basis. More than 50% of Daewoo International’s export sales are derived from its export of steel products including products manufactured by us.

Engineering and Construction

POSCO E&C is one of the leading engineering and construction companies in Korea, primarily engaged in the planning, design and construction of industrial plants and architectural works and civil

33

engineering projects. In particular, POSCO E&C has established itself as one of the premier engineering and construction companies in Korea through:

•     its strong and stable customer base; and

•     its cutting-edge technological expertise obtained from construction of advanced integrated steel plants, as well as participation in numerous modernization and rationalization projects at our Pohang Works and Gwangyang Works.

Leveraging its technical know-how and track record of building some of the leading industrial complexes in Korea, POSCO E&C has also focused on diversifying its operations into construction of high-end apartment complexes and participating in a wider range of architectural works and civil engineering projects, as well as engaging in urban planning and development projects and expanding its operations abroad. One of its landmark urban planning and development projects includes the development of a 5.7 million-square meter area of Songdo International City in Incheon, which POSCO E&C is co-developing with Gale International, a respected real estate developer based in the United States. POSCO E&C also has substantial experience in the energy field obtained from the construction of various power plants for member companies of the POSCO Group, specializing primarily in engineering and construction of LNG and coal-fired thermal power plants. In recent years, POSCO E&C has obtained various orders for such power plants, including LNG-fired power plants in Incheon, Korea and coal-fired thermal power plants in Ventanas, Chile. In response to increasing demand from the energy industry, POSCO E&C plans to continue to target opportunities in power plant construction, which it believes offers significant growth potential, and thereby enhance itsknow-how and profitability. In order to further enhance its expertise, POSCO E&C acquired several companies with technological leadership in their fields in recent years, including acquiring an 88.7% interest in Daewoo Engineering Corporation in 2008 and a 43.1% interest in Sunggin Geotec Corporation in 2010. Daewoo Engineering Corporation is a leading engineering company in Korea with expertise in chemical, petrochemical and industrial plants and civil works, and Sunggin Geotec Corporation is a leading manufacturer in Korea of specialized equipment used in the petrochemical and energy industries.

Energy

We have accumulated several decades of experience and know-how in a wide range ofenergy-related fields, including natural gas and other forms of power generation. As part of our diversification efforts, we strive to identify business opportunities for power generation, renewable energy, LNG logistics and natural resources exploration.

In 2006, we acquired the largest domestic private power utility company that operates LNG combined cycle power generation facilities with total power generation capacity of 1,800 megawatts and renamed it POSCO Power Corporation. POSCO Power expanded its power generation capacity by constructing additional power plants with power generation capacity of 1,200 megawatts that began commercial operation in June 2011. In December 2010, POSCO Power also completed the construction of a 284 megawatts combined cycle power generation facility utilizing by-product gas generated from our Gwangyang Works. We expect POSCO Power’s total power generation capacity to reach approximately 3,300 megawatts by the end of 2011.

In an effort to reduce our dependency on oil, we became the first private company in Korea to import LNG in 2005 and have been using natural gas for energy generation at our steel production facilities. We operate an LNG receiving terminal with total storage capacity of 365,000 cubic meters in Gwangyang.

In order to meet the increasing demand and regulatory requirements for clean energy, POSCO Power signed a strategic partnership agreement in February 2007 with FuelCell Energy, a global leader in the field of molten carbonate fuel cell technology, pursuant to which POSCO Power is exploring opportunities to expand its business into the stationary fuel cell market. In consultation with

34

the FuelCell Energy, the POSCO Power completed construction of a fuel cell stack manufacturing plant with an annual production capacity of 34 megawatts in 2011 with the objective of enhancing the company’s capability to meet the growing domestic demand for fuel cell energy.

We are also actively seeking business opportunities in the exploration and production of oil and natural gas. In 2007, we participated in the Aral Sea Exploration Project in Uzbekistan, purchasing a 9.8% interest from Korea National Oil Corporation. Additionally, we acquired a 12.5% interest in 2008 in the Namangan-Tergachi and Chust-Pap Oil and Gas Exploration Project in Uzbekistan. On September 20, 2010, we also acquired a 68.15% interest in Daewoo International for Won 3.37 trillion. Daewoo International is a global trading company that primarily engages in trading of steel and raw materials as well as investing in energy and mineral development projects throughout the world. In particular, Daewoo International joined a consortium with Korea Gas Corporation, ONGC Videsh Ltd. and The Gas Authority of India Ltd. in November 2002, which made a successful bid in the gas exploration, development and production project in the MyanmarA-1 gas field. In October 2005, the consortium made a successful bid in the gas exploration, development and production project in the MyanmarA-3 gas field, located adjacent to the MyanmarA-1 gas field. In December 2008, the consortium entered into a sales agreement with China National United Oil Corporation to sell the gas produced from theA-1 andA-3 gas fields for a period of 30 years after the commencement of production. In August 2010, Myanmar Oil & Gas Enterprise, the national oil and gas company of Myanmar, acquired a 15% interest in each of the projects. As of December 31, 2010, Daewoo International had invested approximately US$273 million in theA-1 gas field project and approximately US$191 million in theA-3 gas field project and held a 51% interest in each of the projects. Production of gas from these gas fields is expected to commence in 2013.

Such energy and mineral development projects, while entailing higher risks than the traditional trading business, offer higher potential returns. Daewoo International intends to continue to expand its operations by carefully seeking out promising energy development projects abroad. Daewoo International mitigates the risks associated with such investments through subsidies from the Korea National Oil Corporation and the Korea Resources Corporation, government agencies that promote natural resources development activities and subsidize a portion of the investment amount in the event the investor fails to develop viable deposits. If the natural resources development activities are successful, the investor must reimburse the relevant agency for the subsidy amount, together with accrued interest.

Others

We acquired or established several subsidiaries that address specific services to support the operations of Pohang Works and Gwangyang Works. POSCON Co., Ltd., acquired in 1986, provides industrial engineering services to POSCO and its subsidiaries and manufacturing services utilizing automation technology. POSDATA Co., Ltd., founded in 1989, provides information and technology consulting and system network integration and outsourcing services. In January 2010, POSDATA Co., Ltd. merged with POSCON Co., Ltd. and changed its name to POSCO ICT Co., Ltd. POSCO Plant Engineering Co., Ltd., created from merger of POSCO Machinery & Engineering Co., Ltd. and POSCO Machinery Co., Ltd. in January 2010, provides engineering services related to plant construction and operations. POSCO Chemtech Company Ltd., formerly POSCO Refractories and Environment Company, Ltd., specializes in the manufacturing of refractories and lime used in steel manufacturing processes as well as a wide range of chemical products.

Insurance

As of December 31, 2010, our property, plant and equipment are insured against fire and other casualty losses up to Won 22,031 billion. In addition, we carry general insurance for vehicles and accident compensation insurance for our employees to the extent we consider appropriate.

Our principal properties are Pohang Works, which is located at Youngil Bay on the southeastern coast of Korea, and Gwangyang Works, which is located in Gwangyang City in the southwestern region of Korea. We expect to increase our production capacity in the future when we increase our capacity as part of our facilities expansion or as a result of continued modernization and rationalization of our existing facilities. For a discussion of major items of our capital expenditures currently in progress, see “Item 5. Operating and Financial Review and Prospects — Item 5.B. Liquidity and Capital Resources — Liquidity — Capital Expenditures and Capital Expansion.”

Pohang Works

Construction of Pohang Works began in 1970 and ended in 1983. Pohang Works currently has an annual crude steel and stainless steel production capacity of 15.0 million tons. Pohang Works produces a wide variety of steel products. Products produced at Pohang Works include hot rolled sheets, plates, wire rods and cold rolled sheets, as well as specialty steel products such as stainless steel sheets and silicon steel sheets. These products can also be customized to meet the specifications of our customers.

Situated on a site of 8.9 million square meters at Youngil Bay on the southeastern coast of Korea, Pohang Works consists of 40 plants, including iron-making, crude steelmaking and continuous casting and other rolling facilities. Pohang Works also has docking facilities capable of accommodating ships as large as 200,000 tons for unloading raw materials, storage areas for up to 34 days’ supply of raw materials and separate docking facilities for ships carrying products for export. Pohang Works is equipped with a highly advanced computerized production-management system allowing constant monitoring and control of the production process.

The following table sets out Pohang Works’ capacity utilization rates for the periods indicated.

(1) Calculated by dividing actual crude steel and stainless steel output by the actual crude steel and stainless steel production capacity for the relevant period as determined by us.

Gwangyang Works

Construction of Gwangyang Works began in 1985 on a site of 13.7 million square meters reclaimed from the sea in Gwangyang City in the southwestern region of Korea. Gwangyang Works

36

currently has an annual crude steel production capacity of 20.8 million tons. Gwangyang Works specializes in high volume production of a limited number of steel products. Products manufactured at Gwangyang Works include both hot and cold rolled types.

Gwangyang Works is comprised of 51 plants, including iron-making plants, steelmaking plants, continuous casting plants, hot strip mills and thin-slab hot rolling plants. The site also features docking and unloading facilities for raw materials capable of accommodating ships of as large as 300,000 tons for unloading raw materials, storage areas for 38 days’ supply of raw materials and separate docking facilities for ships carrying products for export.

We believe Gwangyang Works is one of the most technologically advanced integrated steel facilities in the world. Gwangyang Works has a completely automated, linear production system that enables the whole production process, from iron-making to finished products, to take place without interruption. This advanced system reduces the production time for hot rolled products to only four hours. Like Pohang Works, Gwangyang Works is equipped with a highly advanced computerized production-management system allowing constant monitoring and control of the production process.

Capacity utilization has kept pace with increases in capacity. The following table sets out Gwangyang Works’ capacity utilization rates for the periods indicated.

	As of or for the Year Ended December 31,
	2006		2007		2008		2009		2010

(2)	Crude steel production capacity increased by an additional 2.80 million tons per year on July 7, 2010. Capacity utilization rate in 2010 was calculated by applying increase in production capacity subsequent to such date.

The Environment

We believe we are in compliance with applicable environmental laws and regulations in all material respects. Our levels of pollution control are higher than those mandated by Government standards. We established an on-line environmental monitoring system with real-time feedback on pollutant levels and a forecast system of pollutant concentration in surrounding areas. We also undergo periodic environmental inspection by both internal and external inspectors in accordance with ISO 14001 standards to monitor execution and maintenance of our environmental management plan. We recently invested in comprehensive flue gas treatment facilities at some of our sinter plants, dust collector at steelmaking plants and coke wastewater treatment facilities. In addition, we recycle most of the by-products from the steelmaking process. We also have been developing environmentally friendly products such as chrome-free steel sheets in an effort to compete with products from the European Union, the United States and Japan and to meet strengthened environmental regulations. Anticipating the trend toward increasing regulation of chrome in various steel products, we introduced chrome-free steel products meeting international environmental standards in 2006 that are used to manufacture automotive oil tanks.

We plan to continue to invest in developing more environmentally friendly steel manufacturing processes. We commenced research and development for a new steel manufacturing technology called FINEX in 1992 jointly with the Research Institute of Industrial Science and Technology and VOEST Alpine, an Australian company, and we completed the construction of our first FINEX plant in May 2003 with an annual steel production capacity of 0.6 million tons and a second FINEX plant in May 2007 with an annual steel production capacity of 1.5 million tons. The total annual steel production capacity of our FINEX plants is 2.1 million tons. We are now preparing for the construction of our third FINEX plant, which we expect will commence operations in 2013.

37

We will continue to refine FINEX, a low cost, environmentally friendly steel manufacturing process that we believe optimizes our production capacity by utilizing non-agglomerated iron ore fines and using non-coking coal as an energy source and a reducing agent. We believe that FINEX offers considerable environmental and economic advantages by eliminating major sources of pollution such as sinter and coke plants, as well as decreasing operating and raw material costs.

Our climate change response program seeks to minimize the risks from changes in climate as well as to maximize the opportunities available in such environment by enhancing the energy efficiency of our production process. We invested Won 80 billion in facilities and equipments for the program in 2010, and we spent Won 28 billion in our research and development activities in 2010 to reduce carbon dioxide emissions. Energy saving activities such as diagnosing energy consumption and holding education workshops resulted in a saving of Won 114 billion in energy expenditures in 2010. We are also involved in a forestation project in Uruguay, which was registered as the world’s first Clean Development Mechanism project sponsored by a steel producer. Clean Development Mechanism is one of the Kyoto Protocol’s project-based mechanisms designed to promote projects that reduce emissions. We have disclosed our carbon dioxide emission levels and efforts to deal with climate changes through various channels, including participating in the Carbon Disclosure Project in 2010. The Carbon Disclosure Project is an organization based in the United Kingdom that works with major corporations around the world to disclose their greenhouse gas emission levels.

POSCO spent Won 215 billion in 2008, Won 297 billion in 2009 and Won 636 billion in 2010 on anti-pollution facilities. In 2010, approximately 11% of our investments in facilities were dedicated to investing in low-emission, anti-pollution facilities.

Item 4A.  Unresolved Staff Comments

We do not have any unresolved comments from the Securities and Exchange Commission staff regarding our periodic reports under the Exchange Act of 1934.

Item 5.  Operating and Financial Review and Prospects

Item 5.A.  Operating Results

The following discussion and analysis is based on our consolidated financial statements, which have been prepared in accordance with Korean GAAP. Korean GAAP varies in certain significant respects from accounting principles generally accepted in the United States of America. Information relating to the nature and effect of such differences is presented in Note 32 of Notes to the Consolidated Financial Statements.

Overview

We are the largest fully integrated steel producer in Korea. We have four reportable operating segments — a steel segment, an engineering and construction segment, a trading segment and a segment that contains operations of all other entities which fall below the reporting thresholds. The steel segment includes production of steel products and sale of such products. The engineering and construction segment includes planning, designing and construction of industrial plants, civil engineering projects and commercial and residential buildings, both in Korea and overseas. The trading segment consists of exporting and importing a wide range of steel products that are both obtained from and supplied to POSCO, as well as between other suppliers and purchasers in Korea and overseas. The “others” segment includes power generation, LNG production, network and system integration, logistics and magnesium coil and sheet production. See Note 31 of Notes to Consolidated Financial Statements.

One of the major factors contributing to our historical performance has been the growth of the Korean economy, and our future performance will depend at least in part on Korea’s general economic growth and prospects. For a description of recent developments that have had and may

38

continue to have an adverse effect on our results of operations and financial condition, see “Item 3. Key Information — Item 3.D. Risk Factors — Korea is our most important market, and our current business and future growth could be materially and adversely affected if economic conditions in Korea deteriorate.” A number of other factors have had or are expected to have a material impact on our results of operations, financial condition and capital expenditures. These factors include:

•     our sales volume, unit prices and product mix;

•     costs and production efficiency;

•     exchange rate fluctuations;

•     acquisition of Daewoo International in September 2010; and

•     transition to International Financial Reporting Standards starting in 2011.

As a result of these factors, our financial results in the past may not be indicative of future results or trends in those results.

Sales Volume, Prices and Product Mix

In recent years, our net sales have been affected by the following factors:

•     the demand for our products in the Korean market and our capacity to meet that demand;

•     our ability to compete for sales in the export market;

•     price levels; and

•     our ability to improve our product mix.

Domestic demand for our products is affected by the condition of major steel consuming industries, such as construction, shipbuilding, automotive, electrical appliances and downstream steel processors, and the Korean economy in general.

Our crude steel output decreased from 34.7 million in 2008 to 31.7 million tons in 2009 and sales volume decreased from 33.5 million tons in 2008 to 31.1 million tons in 2009. In response to sluggish demand from our customers in industries adversely impacted by deteriorating global economic conditions in the second half of 2008, such as automotive and construction industries, we reduced our crude steel production and sales prices in December 2008 and the first quarter of 2009. Signs that the pace of deterioration in market conditions had slowed began to appear in the second quarter of 2009, however, and demand from certain segments of our customer base, including the domestic automotive and construction industries, showed signs of recovery starting in the second quarter of 2009. In response, we began to incrementally increase our crude steel production starting in April 2009 and our production level normalized in the second half of 2009. As a result of production cuts in the first half of 2009, prices for our steel products remained depressed until the third quarter of 2009, during which time prices started to recover and continued to gradually increase up to the end of 2009. In 2010, we increased our crude steel output to 35.3 million tons and our sales volume increased to 38.7 million tons.

In 2009, unit sales price in Won for all of our principal product lines, other than silicon steel sheets, decreased, and the weighted average unit prices for our products decreased by 5.2% in 2009 compared to 2008 despite a depreciation in the average value of the Won against the Dollar in 2009 compared to 2008 that contributed to an increase in our export prices in Won terms. The average exchange rate of the Won against the Dollar depreciated from Won 1,102.6 to US$1.00 in 2008 to Won 1,276.4 to US$1.00 in 2009. Unit sales price of stainless steel products, which accounted for 7.3% of total sales volume, decreased by 23.5% in 2009. Unit sales price of hot rolled products, which accounted for 25.8% of total sales volume, decreased by 7.8% in 2009. Unit sales price of wire rods, which accounted for 7.8% of total sales volume, decreased by 2.8% in 2009. Unit sales price of cold rolled products, which accounted for 36.2% of total sales volume, decreased by 2.2% in 2009. Unit

39

sales price of plates, which accounted for 14.7% of total sales volume, decreased by 1.9% in 2009. On the other hand, unit sales price of silicon steel sheets, which accounted for 2.9% of total sales volume, increased by 8.1% in 2009.

In 2010, unit sales price in Won for all of our principal product lines, other than silicon steel sheets, increased, and the weighted average unit prices for our products increased by 8.5% in 2010 compared to 2009 despite an appreciation in the average value of the Won against the Dollar in 2010 compared to 2009 that contributed to a decrease in our export prices in Won terms. The average exchange rate of the Won against the Dollar appreciated from Won 1,276.4 to US$1.00 in 2009 to Won 1,156.3 to US$1.00 in 2010. Unit sales price of hot rolled products, which accounted for 22.1% of total sales volume, increased by 16.3% in 2010. Unit sales price of wire rods, which accounted for 6.1% of total sales volume, increased by 5.8% in 2010. Unit sales price of stainless steel products, which accounted for 6.7% of total sales volume, increased by 3.6% in 2010. Unit sales price of cold rolled products, which accounted for 35.1% of total sales volume, increased by 3.6% in 2010. Unit sales price of plates, which accounted for 11.9% of total sales volume, increased by 2.7% in 2010. On the other hand, unit sales price of silicon steel sheets, which accounted for 2.8% of total sales volume, decreased by 0.7% in 2010.

Partly in response to the weakening demand resulting from the global economic downturn, our export prices in dollar terms decreased in the first half of 2009. Starting in the third quarter of 2009, our export prices in dollar terms gradually started to recover due to an increase in demand driven by improvement in business confidence and higher level of economic activities as well as a decrease in our inventory level. This trend continued in the first half of 2010, but we maintained similar pricing levels in the second half of 2010. We may decide to adjust our future export sales prices on an on-going basis subject to market demand for our products, the production outlook of the global steel industry and global economic conditions in general. See “Item 4. Information on the Company — Item 4.B. Business Overview — Markets — Exports.”

The table below sets out the average unit sales prices for our semi-finished and finished steel products for the periods indicated.

	For the Year Ended December 31,
Products	2008		2009		2010
	(In thousands of Won per ton)
Hot rolled products	W	800.3	W	737.5	W	857.6

Costs and Production Efficiency

Our major costs and operating expenses are raw material purchases, depreciation, labor and other purchases. The table below sets out a breakdown of our total costs and operating expenses as a percentage of our net sales for the periods indicated.

	For the Year Ended December 31,
	2008			2009			2010
	(Percentage of net sales)
Cost of goods sold		78.0	%		84.2	%		85.0	%
Selling and administrative expenses(1)		4.8			5.3			5.5
Total operating expenses		82.8			89.5			90.5
Gross margin		22.0			15.8			15.0
Operating margin		17.2			10.5			9.5

(1) See Note 25 of Notes to Consolidated Financial Statements.

In 2010, our gross margin decreased to 15.0% from 15.8% in 2009 as the increase in sales was outpaced by the increase in cost of goods sold in 2010. Our gross margin was negatively affected in 2010 due to the consolidation of Daewoo International’s results in 2010 compared to no such consolidation in 2009. Daewoo International, as a global trading company that primarily engages in trading of steel and raw materials, typically recognizes revenues from its trading activities on a gross basis that results in lower margin levels. We are closely monitoring changes in market conditions and we implemented the following measures in recent years to address challenges posed by the global economic downturn:

•     pursuing cost reduction through enhancing product designs, improving productivity and reducing transportation costs;

•     focusing on marketing activities to increase our domestic market share and export sales; and

•     establishing a special sales committee to more effectively respond to changes in market trends and preparing responses to various scenarios of future sales.

Our production efficiency prior to the recent global economic downturn had benefited from operation near or in excess of stated capacity levels. Production capacity represents our maximum production capacity that can be achieved with an optimal level of operations of our facilities. In 2009, we reduced our crude steel production in the first quarter of the year but began to incrementally increase our crude steel production starting in April 2009, and our production level normalized in the second half of 2009. See “Item 4. Information on the Company — Item 4.D. Property, Plants and Equipment.”

The table below sets out certain information regarding our efficiency in the production of steel products for the periods indicated.

	For the Year Ended December 31,
	2008		2009		2010
Crude steel and stainless steel production capacity (million tons per year)(1)		34.6		34.6		37.6
Actual crude steel and stainless steel output (million tons)		34.7		31.7		35.3
Capacity utilization rate (%)		100.3		91.6		93.9
Steel product sales (million tons)(2)		33.5		31.1		38.7

(1)	Includes production capacity of POSCO Specialty Steel Co., Ltd. and Zhangjiagang Pohang Stainless Steel Co., Ltd.
(2)	Includes sales by our consolidated sales subsidiaries of steel products purchased by them from third parties, including trading companies to which we sell steel products. These sales amounted to approximately 0.9 million tons in 2008, 0.5 million tons in 2009 and 1.2 million tons in 2010.

Exchange Rate Fluctuations

The Won has fluctuated significantly against major currencies in recent years, which has affected our results of operations and liquidity. The market average exchange rate, as announced by the Seoul Money Brokerage Services, Ltd., depreciated from Won 938.2 to US$1.00 as of December 31, 2007 to Won 1,573.6 to US$1.00 as of March 3, 2009 but appreciated to Won 1,075.0 to US$1.00 on June 23, 2011. Depreciation of the Won may materially affect the results of our operations because, among other things, it causes:

•     an increase in the amount of Won required for us to make interest and principal payments on our foreign currency-denominated debt, which accounted for approximately 53.5% of our total long-term debt (excluding discounts on debentures issued and including current portion) as of December 31, 2010;

•     an increase in Won terms in the costs of raw materials and equipment that we purchase from overseas sources and a substantial portion of our freight costs, which are denominated in Dollars; and

•     foreign exchange translation losses on liabilities, which lower our earnings for accounting purposes.

Appreciation of the Won, on the other hand, (i) causes our export products to be less competitive by raising our prices in Dollar terms and (ii) reduces net sales and accounts receivables in Won from export sales, which are primarily denominated in Dollars. However, because of the larger positive effects of the appreciation of the Won (i.e., the reverse of the negative effects caused by the depreciation of the Won, as discussed above), appreciation of the Won generally has a positive impact on our results of operations. See “Item 3. Key Information — Item 3.A. Selected Financial Data — Exchange Rate Information.”

We attempt to minimize our exposure to currency fluctuations by attempting to maintain export sales, which result in foreign currency receipts, at a level that covers foreign currency obligations to the extent feasible. As a result, a decrease in our export sales could increase our foreign exchange risks. From time to time we also enter into cross currency swap agreements in the management of our interest rate and currency risks and currency forward contracts with financial institutions to reduce the fluctuation risk of future cash flows. As of December 31, 2010, we had entered into swap contracts, currency forward contracts and currency future contracts. The net valuation loss of our derivatives contracts was Won 24 billion and the net transaction gain was Won 15 billion in 2010. We may incur further losses under our existing contracts or any swap or other derivative product transactions entered into in the future. See Note 24 of Notes to Consolidated Financial Statements.

Acquisition of Daewoo International in September 2010

On September 20, 2010, we acquired a 68.15% interest in Daewoo International for Won 3.37 trillion. On a consolidated basis under Korean GAAP, Daewoo International generated revenues of Won 16,112 billion and net income of Won 119 billion in 2010, compared to revenues of Won 11,544 billion and net income of Won 131 billion in 2009. On a consolidated basis under Korean GAAP, Daewoo International had total assets of Won 5,652 billion and total shareholders’ equity of Won 1,589 billion as of December 31, 2010 and total assets of Won 4,695 billion and total shareholders’ equity of Won 1,399 billion as of December 31, 2009.

In accordance with Korean GAAP, the results of operations of Daewoo International for the year ended December 31, 2010 are consolidated in their entirety in each line item of our consolidated statement of income in 2010 as if the acquisition had occurred on January 1, 2010 and thepre-acquisition net earnings of Daewoo International are deducted in determining our consolidated net income.

Transition to International Financial Reporting Standards Starting in 2011

In March 2007, the Financial Services Commission and the Korea Accounting Institute announced a road map for the adoption of Korean IFRS, pursuant to which all listed companies in Korea, including us, will be required to prepare their annual financial statements beginning in 2011 that differ in certain respects from IFRS applied in other countries.

In preparation of such adoption, we began preparing our internal financial statements under both Korean GAAP and Korean IFRS starting in January 2010. Beginning in 2011, we have discontinued reporting under Korean GAAP with reconciliation to U.S. GAAP and instead have commenced reporting under Korean IFRS and we also plan to release annual financial statements prepared pursuant to IFRS as issued by the IASB. Although our accounting department is currently analyzing the effects of adopting IFRS on our annual financial statements, it is not possible to estimate with any degree of certainty the exact impact on our annual financial statements from such adoption because the IFRS accounting policies to be adopted by us for such financial statements have not been finalized. Accordingly, there can be no assurance that the adoption of IFRS will not adversely affect our reporting results of operations or financial condition.

Inflation

Inflation in Korea, which was 4.7% in 2008, 2.8% in 2009, and 2.9% in 2010, has not had a material impact on our results of operations in recent years.

Critical Accounting Estimates

Our financial statements are prepared in accordance with Korean GAAP and reconciled to U.S. GAAP. The preparation of these financial statements under Korean GAAP as well as the U.S. GAAP reconciliation requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. We have identified the following areas where we believe assumptions and estimates are particularly critical to our financial statements:

Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts for exposures in our receivable balances that represent our estimate of probable losses in our short-term and long-term receivable balances from the inability of our customers to make required payments. If the financial condition of our customers were to deteriorate and negatively impact their ability to make payments, additional allowances may be required. Determining the allowance for doubtful accounts requires significant management judgment and estimates including, among others, the credit worthiness of our customers, experience of historical collection patterns, potential events and circumstances affecting future collections and the ongoing risk assessment of our customers’ ability to pay.

Trade account receivables are analyzed on a regular basis and, upon our becoming aware of a customer’s inability to meet its financial commitments to us, we reduce the value of the receivable is reduced through a charge to the allowance for doubtful accounts. In addition, we record a charge to the allowance for doubtful accounts upon receipt of customer claims in connection with sales that management estimates are unlikely to be collected in full. The percentage of allowance for doubtful accounts to gross account receivables was 3.72% as of December 31, 2010 and 4.52% as of December 31, 2009. The percentage of allowance for doubtful accounts to gross account receivables as of December 31, 2010 decreased compared to December 31, 2009 primarily due to a decrease in accounts receivables that were overdue.

Specifically, allowance for doubtful accounts are recorded when any of the following loss events occurs: (i)��there is objective evidence as to uncollectibility of the account observed through

43

bankruptcy, default or involuntary dissolution of the customer; (ii) we lose a lawsuit against the customer or our right of claim gets extinguished; (iii) our costs to collect the account exceed the payments to be received; or (iv) dispute with the customer over the collection of the account persists over three years.

The actual average annual uncollected percentage rate of accounts receivables resulting in write-offs for the three years in the period ended December 31, 2010 was 0.59%. These historical results, as well as current known conditions impacting the collectability of our accounts receivable balances, are significant factors for us when we estimate the amount of the necessary allowance for doubtful accounts. Historically, losses from uncollectible accounts receivables have been within expectations and in line with the allowances established. However, unforeseen circumstances such as adverse market conditions that deviate significantly from our estimates may require us to change the timing of, and make additional allowances to, our receivable balances. In this case, our results of operations, financial condition and net worth could be materially and adversely affected.

Valuation of Investment Securities and Derivatives

We invest in various financial instruments including debt and equity securities and derivatives. Depending on the accounting treatment specific to each type of financial instrument, an estimate of fair value is required to determine the instrument’s effect on our consolidated financial statements.

If available, quoted market prices provide the best indication of fair value. We determine the fair value of our financial instruments using quoted market prices when available, including quotes from dealers trading those securities. If quoted market prices are not available, we determine the fair value based on pricing or valuation models, quoted prices of instruments with similar characteristics, or discounted cash flows. Determining the fair value of unlisted financial instruments involves a significant degree of management resources and judgment as no quoted prices exist and such securities are generally very thinly traded. The fair value of unlisted equity securities held for investment (excluding those of affiliates and subsidiaries) is based on the latest obtainable net asset value of the investees, which often reflects cost or other reference events. Derivatives for which quoted market prices are not available are valued using valuation models such as the discounted cash flow method. The key inputs used in the valuation of such derivatives depend upon the type of derivative and the nature of the underlying instrument and include interest rate yield curves, foreign exchange rates, the spot price of the underlying instrument, volatility and correlation. The fair values based on pricing and valuation models, discounted cash flow analysis, or net asset values are subject to various assumptions used that, if changed, could significantly affect the fair value of the investments.

When the fair value of a listed equity security or the net equity value of an unlisted equity security declines compared to acquisition cost and is not expected to recover (impaired investment security), the value of the equity security is adjusted to its fair value or net asset value, with the valuation loss charged to current operations. When the fair value of aheld-to-maturity or anavailable-for-sale investment debt security declines compared to the acquisition cost and is not expected to recover (impaired investment security), the carrying value of the debt security is adjusted to its fair value with the resulting valuation loss charged to current operations.

As part of this impairment review, the investee’s operating results, net asset value and future performance forecasts as well as general market conditions are taken into consideration. If we believe, based on this review, that the market value of an equity security or a debt security may realistically be expected to recover, the loss will continue to be classified as temporary. If economic or specific industry trends worsen beyond our estimates, valuation losses previously determined to be recoverable may need to be charged as a valuation loss in current operations.

Significant management judgment is involved in the evaluation of declines in value of individual investments. The estimates and assumptions used by our management to evaluate declines in value can be impacted by many factors, such as the financial condition, earnings capacity and near-term

44

prospects of the company in which we have invested, the length of time and the extent to which fair value has been less than cost, and our intent and ability to hold the related security for a period of time sufficient to allow for any recovery in market value. The evaluation of these investments is also subject to the overall condition of the economy and its impact on the capital markets. Any changes in these assumptions could significantly affect the valuation and timing of recognition of valuation losses classified as other than temporary.

We have estimated fair values of material non-marketable securities. We estimated these fair values based on pricing or valuation models, quoted prices of instruments with similar characteristics, or discounted cash flow models. The discounted cash flow model valuation technique is based on the estimated cash flow projections of the underlying investee. Key assumptions and estimates include market conditions, revenue growth rates, operating margin rates, income tax rates, depreciation and amortization rates, the level of capital expenditures, working capital amounts and the discount rates. These estimates are based on historical results of the investee and other market data. In these cash flows projections, the two most significant estimates are the discount rates and revenue growth rates. If the discount rates used in these valuations were increased by one percentage point, then the estimated fair values would have decreased by 18% in total. In addition, if the revenue growth rate assumptions were decreased by 1% in the cash flow models, then the estimated fair values would have decreased by 12% in total.

We recognized losses on impairment of investments of Won 121 billion in 2008, Won 286 billion in 2009 and Won 52 billion in 2010. Loss on impairment of investments increased in 2009 primarily due to an impairment loss of Won 209 billion resulting from a decrease in the fair value of our investment in LG Powercom. We recorded such impairment loss because the estimated recoverable amount of our investment in LG Powercom was less than its carrying value.

Historically, our estimates and assumptions used to evaluate impairment of investments have been within expectations. However, unforeseen circumstances such as adverse market conditions that deviate significantly from our estimates may require us to recognize additional losses on impairment of investments. We base our fair value estimates on assumptions we believe to be reasonable, but which are unpredictable and inherently uncertain. The use of alternative estimates and assumptions could increase or decrease the estimated fair values of our investments and potentially result in different impacts on our results of operations.

Long-lived Assets

The depreciable lives and salvage values of our long-lived assets are estimated and reviewed each year based on industry practices and prior experience to reflect economic lives of long-lived assets. Also, these assets are reviewed for impairment if events or changes in circumstances indicate that the carrying amount of an asset may not be recovered. There were no significant changes in assumption to estimated useful lives or salvage value assumptions in 2008, 2009 and 2010. The recoverable amount is measured at the greater of net selling price or value in use. When the book value of long-lived asset exceeds the recoverable value of the asset due to obsolescence, physical damage or a decline in market value and such amount is material, the impairment of asset is recognized and the asset’s carrying value is reduced to its recoverable value and the resulting impairment loss is charged to current operations. Such recoverable value is based on our estimates of the future use of assets that is subject to changes in market conditions.

Our estimates of the useful lives and recoverable values of long-lived assets are based on historical trends adjusted to reflect our best estimate of future market and operating conditions. Also, our estimates include the expected future period in which the future cash flows are expected to be generated from continuing use of the assets that we review for impairment and cash outflows to prepare the assets for use that can be directly attributed or allocated on a reasonable and consistent basis. If applicable, estimates also include net cash flows to be received or paid for the disposal of the assets at the end of their useful lives. As a result of the impairment review, when the sum of the

45

discounted future cash flows expected to be generated by the assets is less than the book value of the assets, we recognize impairment losses based on the recoverable value of those assets. We make a number of significant assumptions and estimates in the application of the discounted cash flow model to forecast cash flows, including business prospects, market conditions, selling prices and sales volume of products, costs of production and funding sources. The estimated cash flow forecast amounts are derived from the most recent financial budgets for the next five years. For periods beyond the five year forecast period, we use a terminal value approach to estimate the cash flows for the remaining years based on an expected estimated growth rate. This estimated growth rate is based on actual historical results. As of December 31, 2010, we estimated an average discount rate of 10.35% and an average rate of revenue growth of 6.37%. However, given the current economic environment, it is likely that the estimates and assumptions will be more volatile than they have been in the past. Further impairment charges may be required if triggering events occur, such as adverse market conditions, that suggest deterioration in an asset’s recoverability or fair value. Assessment of the timing of when such declines become other than temporary and the amount of such impairment is a matter of significant judgment. Results in actual transactions could differ from those estimates used to evaluate the impairment of such long-lived assets. If our future cash flow projections are not realized, either because of an extended recessionary period or other unforeseen events, impairment charges may be required in future periods.

If the estimated average discount rates used in these valuations were increased by one percentage point, then the estimated fair values would have decreased by 19% in total. If the estimated average rate of revenue growth rate were decreased by 1%, then the estimated fair values would have decreased by 18% in total.

Inventories

Inventories are stated at the lower of cost or net realizable value. Costs of inventories are determined using the moving-weighted average or weighted average method whilematerials-in-transit are determined using the specific identification method. Amounts of inventory are written down to net realizable value due to losses occurring in the normal course of business and the allowance is reported as a contra inventory account, while the related charge is recognized in cost of goods sold.

The net realizable value is determined based on the latest selling price available at the end of each quarter taking into account the directly attributable selling costs. The latest selling price is the base price which is the negotiated selling price based upon the recent transactions entered into with major customers. Considering that our inventory turnover is approximately two months and inventories at balance sheet date would be sold during the following two months, we perform valuation of inventories using the base price as of the balance sheet date and adjust for significant changes in selling price occurring subsequent to the balance sheet date. The selling price range used for determining the net realizable value of our inventories ranged from the inventory cost amount less 2.3% of gross profit margin to the inventory cost amount plus 22.3% of gross profit margin. For inventories in which expected selling prices are less than the cost amount, the necessary adjustment to write down the inventories to net realizable value is made.

Deferred Income Tax Assets

In assessing the realization of our deferred income tax assets, our management considers whether it is probable that a portion or all of the deferred income tax assets will not be realized. The ultimate realization of our deferred income tax assets is dependent on whether we are able to generate future taxable income in specific tax jurisdictions during the periods in which temporary differences become deductible.

Our management has scheduled the expected future reversals of the temporary differences and projected future taxable income in making this assessment. However, changes in our evaluation

46

of our deferred income tax assets from period to period could have a significant effect on our net results and financial condition.

Operating Results — 2010 Compared to 2009

Sales

Our sales increased by 64.5% to Won 60,638 billion in 2010 from Won 36,855 billion in 2009. The increase in sales was due primarily to the consolidation of Daewoo International’s revenues of Won 16,112 billion in 2010 as a result of the acquisition of Daewoo International in September 2010 compared to no consolidation of such revenues in 2009, as well as an increase in the sales volume and the weighted average unit sales price per ton of our steel products in 2010 compared to 2009. Including the steel trading activities of Daewoo International in 2010, our overall sales volume of steel products increased by 24.5% in 2010 compared to 2009, and the weighted average unit sales price per ton of our steel products increased by 8.6% in 2010 compared to 2009.

The sales volume of each of our principal product lines, other than wire rods which showed a slight decrease, increased in 2010 compared to 2009. Our sales volume of cold rolled products, which accounted for 35.1% of total sales volume in 2010, showed the greatest increase among our principal product lines with an increase of 20.7% primarily due to an increase in demand from the automotive industry. Our sales volume of silicon steel sheets, which accounted for 2.8% of total sales volume in 2010, increased by 20.1% primarily due to an increase in demand from manufacturers of power transformers and generators. Our sales volume of stainless steel products, which accounted for 6.7% of total sales volume in 2010, increased by 13.7% primarily due to an increase in demand from the automotive industry and the household goods industry. On the other hand, sales volume of wire rods, which accounted for 6.1% of total sales volume in 2010, decreased by 1.6% primarily due to increased purchase of wire rods imported from China by domestic customers.

The unit sales prices in Won of each of our principal product lines, other than silicon steel sheets, increased in 2010 compared to 2009. See “— Overview — Sales Volume, Prices and Product Mix” above. The weighted average unit prices of our products increased by 8.6% in 2010 compared to 2009 primarily due to increases in the sales prices of our principal products ranging from 9.8% to 25.0% in May 2010 in response to the global economic recovery following reductions in the sales prices of our principal products in May 2009 in response to the global economic downturn, the impact of which increase was partially offset by an appreciation in the average value of the Won against the Dollar in 2010 compared to 2009 that contributed to a decrease in our export prices in Won terms. The average exchange rate of the Won against the Dollar, as announced by Seoul Money Brokerage Services, Ltd., appreciated to Won 1,156.3 to US$1.00 in 2010 from Won 1,276.4 to US$1.00 in 2009.

Domestic Sales

Our sales to domestic customers increased by 36.4% in terms of sales revenues and by 12.2% in terms of sales volume of steel products in 2010 compared to 2009. Our domestic sales accounted for approximately 56.4% of our total sales volume of steel products in 2010, compared to 62.6% in 2009. The increase in domestic sales revenues in 2010 compared to 2009 was attributable primarily to an increase in the sales volume and the weighted average unit sales price per ton of our steel products sold to domestic customers in 2010 compared to 2009. In 2010, the volume of steel products sold in Korea increased primarily due to an increase in demand from the automotive industry and the household goods industry, the impact of which was partially offset by a decrease in demand from the construction industry.

Export Sales

Our export sales and overseas sales to customers abroad increased by 108.8% in terms of sales revenues and by 45.0% in terms of sales volume of steel products in 2010 compared to 2009. Our export sales and overseas sales to customers abroad accounted for approximately 43.6% of our

47

total sales volume of steel products in 2010 compared to 37.4% in 2009. The increase in export sales and overseas sales to customers abroad in terms of sales revenues in 2010 compared to 2009 was attributable primarily to the consolidation of Daewoo International’s export sales and overseas sales to customers abroad in 2010 as a result of the acquisition of Daewoo International in 2010 compared to no consolidation of such sales in 2009, as well as an increase in the sales volume and the weighted average unit sales price per ton of our steel products sold abroad in 2010 compared to 2009. In 2010, the volume of our export sales and overseas sales to customers abroad increased primarily due to an increase in demand from customers in Southeast Asia, North America, Japan and Europe.

Cost of Goods Sold

Our cost of goods sold increased by 66.1% to Won 51,561 billion in 2010 from Won 31,037 billion in 2009. The increase in cost of goods sold was due primarily to the consolidation of Daewoo International’s cost of goods sold of Won 15,164 billion in 2010 as a result of the acquisition of Daewoo International in 2010 compared to no consolidation of such cost in 2009, as well as an increase in our sales volume of steel products as discussed above and increases in the average prices in Won terms of key raw materials that were used to manufacture finished goods sold in 2010 compared to 2009.

Gross Profit

Our gross profit in 2010 increased by 56.0% to Won 9,077 billion from Won 5,818 billion in 2009. Our gross margin in 2010 decreased to 15.0% from 15.8% in 2009 as the increase in sales was outpaced by the increase in cost of goods sold in 2010, as described above. Our gross margin was negatively affected in 2010 due to the consolidation of Daewoo International’s results in 2010 compared to no such consolidation in 2009. Daewoo International, as a global trading company that primarily engages in trading of steel and raw materials, typically recognizes revenues from its trading activities on a gross basis that results in lower margin levels.

Selling and Administrative Expenses

Our selling and administrative expenses increased by 71.3% to Won 3,339 billion in 2010 from Won 1,949 billion in 2009. The significant increase in our selling and administrative expenses resulted principally from increases in transportation expenses, labor-related expenses, fees and charges and depreciation expense. Such factors were principally attributable to the following:

•     Transportation expenses increased by 93.1% to Won 1,251 billion in 2010 from Won 648 billion in 2009 principally due to the consolidation of Daewoo International’s transportation expenses in 2010 following the acquisition of Daewoo International in 2010 compared to no consolidation of such expenses in 2009, as well as an increase in our sales volume as a result of the general recovery of the global economy in 2010 that led to an increase in demand for, and shipping of, our products.

•     Our labor-related expenses included in selling and administrative expenses, which consist of salaries, welfare and provision for severance benefits, increased by 66.9% to Won 751 billion in 2010 from Won 450 billion in 2009, primarily reflecting the consolidation of labor-related expenses of employees of Daewoo International in 2010 following the acquisition of Daewoo International in 2010 compared to no consolidation of such expenses in 2009, as well as increases in our incentive pay and related provision for severance benefits that reflect an increase in our operating income.

•     Fees and charges, which include certain administrative fees and professional service fees, increased by 69.0% to Won 267 billion in 2010 from Won 158 billion in 2009 primarily due to the consolidation of Daewoo International’s fees and charges in 2010 as a result of the acquisition of Daewoo International in 2010 compared to no consolidation of such expenses in 2009. Fees and charges of Daewoo International in 2010 consisted primarily

48

of fees paid to financial institutions in connection with accounts receivable-related financing activities as well as legal and consulting fees incurred in connection with its sale to us.

•     Depreciation expense increased by 86.8% to Won 231 billion in 2010 from Won 124 billion in 2009 primarily due to the amortization of certain intangible assets, including goodwill, acquired by us in connection with our acquisitions of Daewoo International and Sungjin Geotec in 2010.

Operating Income

Due to the factors described above, our operating income increased by 48.3% to Won 5,738 billion in 2010 from Won 3,868 billion in 2009. Our operating margin decreased to 9.5% in 2010 from 10.5% in 2009.

Non-operating Income (Expenses), Net

Our net non-operating expenses increased by 210.9% to Won 401 billion in 2010 from Won 129 billion in 2009 primarily due to a net loss on foreign currency translation in 2010 compared to a net gain on foreign currency translation in 2009 and an increase in interest expense, the impact of which was partially offset by a net equity in earnings of equity method accounted investees in 2010 compared to a net equity in losses of equity method accounted investees in 2009 and a decrease in loss on impairment of investments. Such factors were principally attributable to the following:

•     We recorded net loss on foreign currency translation of Won 203 billion in 2010 compared to a net gain of Won 436 billion in 2009 as the Won depreciated against the Yen in 2010 while it appreciated against the Yen in 2009. The Won appreciated at a slower level against the Dollar in 2010 compared to 2009. In terms of the market average exchange rate announced by Seoul Money Brokerage Services, Ltd., the Won depreciated against the Yen to Won 1,397.1 per Yen 100 as of December 31, 2010 from Won 1,262.8 per Yen 100 as of December 31, 2009, while the Won appreciated to Won 1,262.8 per Yen 100 as of December 31, 2009 from Won 1,393.9 per Yen 100 as of December 31, 2008. The Won appreciated against the Dollar to Won 1,138.9 to US$1.00 as of December 31, 2010 from Won 1,167.6 to US$1.00 as of December 31, 2009, as well as to Won 1,167.6 to US$1.00 as of December 31, 2009 from Won 1,257.5 to US$1.00 as of December 31, 2008.

•     Our interest expense increased by 23.5% to Won 657 billion in 2010 from Won 532 billion in 2009 primarily due to an increase in the average balance of our short-term borrowings and long-term debt held in 2010 compared to 2009, the impact of which was offset in part by a general decrease in interest rates in Korea from 2009 to 2010.

These factors were partially offset by the following:

•     We recorded a net equity in earnings of equity method accounted investees of Won 303 billion in 2010 compared to a net equity in losses of equity method accounted investees of Won 7 billion in 2009 primarily as a result of a 393.3% increase in equity in earnings of equity method accounted investees to Won 371 billion in 2010 from Won 75 billion in 2009 primarily due to the consolidation of Daewoo International’s net equity in earnings of equity method accounted investees, including its equity interest in Kyobo Life Insurance, compared to no consolidation of such net equity in earnings in 2009.

•     Our loss on impairment of investments decreased by 81.8% to Won 52 billion in 2010 compared to Won 286 billion in 2009. The loss on impairment of investments of Won 52 billion in 2010 primarily resulted from the impairment loss of Won 40 billion incurred by POSCO E&C in 2010 from its real property investments. The loss on impairment of investments of Won 286 billion in 2009 primarily resulted from the impairment loss of Won 207 billion in our investment in LG Powercom in 2009.

49

Income Tax Expense

Income tax expense increased by 107.6% to Won 1,113 billion in 2010 from Won 536 billion in 2009 primarily due to a 42.7% increase in income before income tax expense and net income (loss) of consolidated subsidiaries before acquisition as well as a 51.5% decrease in net credit in adjustments, including tax credit, to Won 179 billion in 2010 from Won 369 billion in 2009. Our effective tax rates were 20.8% in 2010 and 14.3% in 2009. Our effective tax rate increased in 2010 due to a decrease in tax credits as well as no tax refund recognized in 2010. In 2009, we obtained a tax refund related to additional tax payments made in 2005, which refund was finalized by the tax tribunal in 2009.

Net Income

Due to the factors described above, our net income increased by 30.1% to Won 4,218 billion in 2010 from Won 3,242 billion in 2009.

Segment Results — Steel

Our sales to external customers increased by 27.0% to Won 43,806 billion in 2010 from Won 34,503 billion in 2009. After adjusting for inter-segment transactions, our net sales increased by 20.0% to Won 34,080 billion in 2010 from Won 28,413 billion in 2009, primarily as a result of an increase in our sales volume of steel products and, to a lesser extent, an increase in the average unit sales price per ton of steel products sold by us.

Operating income increased by 64.7% to Won 5,300 billion in 2010 from Won 3,217 billion in 2009, as the 20.0% increase in the segment’s net sales more than outpaced increases in cost of goods sold and selling and administrative expenses, primarily due to the reasons discussed above. Operating margin, which is operating income as a percentage of total sales prior to adjusting for inter-company sales, increased to 12.1% in 2010 from 9.3% in 2009. Depreciation and amortization increased by 11.5% to Won 2,641 billion in 2010 from Won 2,369 billion in 2009, primarily due to an increase in capital investment in our facilities in recent years for production of higher value-added products.

Segment Results — Engineering and Construction

Our sales to external customers decreased by 2.3% to Won 7,581 billion in 2010 from Won 7,760 billion in 2009. After adjusting for inter-segment transactions, our net sales increased by 7.9% to Won 4,216 billion in 2010 from Won 3,908 billion in 2009, primarily due to an increase in sales from POSCO E&C’s plant operations related to the construction of LNG power plants in Incheon and coal power plants in Ventanas, Chile.

Operating income decreased by 7.7% to Won 319 billion in 2010 from Won 346 billion in 2009 as the market conditions in the domestic construction industry weakened in 2010, resulting in an increase in competition. The segment’s operating margin, which is operating income as a percentage of total sales prior to adjusting for inter-company sales, decreased to 4.2% in 2010 from 4.5% in 2009.

Segment Results — Trading

Our sales to external customers increased by 507.7% to Won 25,039 billion in 2010 from Won 4,120 billion in 2009, primarily due to the consolidation of Daewoo International’s revenues in 2010 as a result of the acquisition of Daewoo International compared to no consolidation of such revenues in 2009, and to a lesser extent, an increase in the trading volume as well as the average unit sales price per ton of steel products sold. After adjusting for inter-segment transactions, our net sales increased by 533.1% to Won 18,880 billion in 2010 from Won 2,982 billion in 2009.

50

Operating income increased by 615.9% to Won 235 billion in 2010 from Won 33 billion in 2009, and the segment’s operating margin, which is operating income as a percentage of total sales prior to adjusting for inter-company sales, increased to 0.9% in 2010 from 0.8% in 2009.

Segment Results — Others

The “others” segment includes power generation, LNG production, network and system integration, logistics and magnesium coil and sheet production. Our sales to external customers increased by 71.6% to Won 5,869 billion in 2010 from Won 3,420 billion in 2009. Our sales increased in 2010 primarily due to an increase in revenues of POSCO Power Corporation as well as the consolidation of revenues of the subsidiaries of Daewoo International Corporation and Sungjin Geotec Co., Ltd. in 2010 compared to no such consolidation in 2009. After adjusting for inter-segment transactions, our net sales increased by 123.1% to Won 3,462 billion in 2010 from Won 1,552 billion in 2009.

Operating income increased by 48.0% to Won 397 billion in 2010 from Won 268 billion in 2009 primarily due to the consolidation of operating income of the subsidiaries of Daewoo International Corporation in 2010 compared to no such consolidation in 2009. The segment’s operating margin, which is operating income as a percentage of total sales prior to adjusting for inter-company sales, decreased to 6.8% in 2010 from 7.8% in 2009.

Operating Results — 2009 Compared to 2008

Sales

Our sales in 2009 decreased by 11.7% to Won 36,855 billion from Won 41,743 billion in 2008 primarily due to a 7.4% decrease in the sales volume of our steel products as well as a decrease of 5.2% in the average unit sales price per ton of our steel products, as discussed in “— Overview — Sales Volume, Prices and Product Mix” above.

Sales volume of silicon steel sheets, which accounted for 2.9% of total sales volume, showed the greatest decrease among our major steel product categories in 2009 with a decrease of 12.8%. Sales volume of cold rolled products, which accounted for 36.2% of total sales volume, decreased by 11.7%. Sales volume of hot rolled products, which accounted for 25.8% of total sales volume, decreased by 7.8%. Sales volume of plates, which accounted for 14.7% of total sales volume, decreased by 6.1%. Sales volume of wire rods, which accounted for 7.8% of total sales volume, decreased by 4.4%. On the other hand, sales volume of stainless steel products, which accounted for 7.3% of total sales volume, increased by 10.7%. See “Item 4. Information on the Company — Item 4.B. Business Overview — Major Products.”

Domestic Sales

Our sales to domestic customers in 2009 compared to 2008 decreased by 16.2% in terms of sales revenues (including sales of non-steel products and services) and decreased by 15.1% in terms of sales volume of steel products. In 2009, our sales to domestic customers accounted for approximately 62.6% of our total sales volume of steel products, compared to 68.3% in 2008. The decrease in domestic sales revenues in 2009 compared to 2008 was attributable primarily to a decrease in our sales volume to domestic customers as we strategically focused on increasing our sales to customers abroad in 2009 due to weak domestic demand and, to a lesser extent, a decrease in the price of steel products sold in Korea.

Export Sales

Our export sales and overseas sales to customers abroad in 2009 decreased by 3.6% in terms of sales revenues (including sales of non-steel products and services). The decrease in export sales and overseas sales to customers abroad in terms of sales revenues in 2009 compared to 2008 was

51

attributable to a decrease in the price of steel products sold abroad, which was offset in part by an increase in sales volume to customers abroad. In response to weak domestic demand for steel products in the first half of 2009, we strategically focused on increasing our sales to customers abroad in 2009. In part due to such strategy, our export sales and overseas to customers abroad in 2009 increased by 9.4% in terms of sales volume of steel products compared to 2008, and export sales and overseas sales to customers abroad as a percentage of total sales volume increased to 37.4% of our total sales volume of steel products in 2009 compared to 31.7% in 2008.

Cost of Goods Sold

Our cost of goods sold increased by 4.7% to Won 31,037 billion from Won 32,562 billion in 2008. The decrease in cost of goods sold was attributable primarily to a decrease in our sales volume of steel products discussed above as well as decreases in the average prices of key raw materials. The average market price of coal per wet metric ton (benchmark free on board price of Australian premium hard coking coal) decreased significantly by 57.0% to US$129 in 2009 from US$300 in 2008, and the average market price of iron ore per dry metric ton (benchmark free on board price of Australian iron ore fines with iron (Fe) 60% content) decreased by 32.9% to US$58.20 in 2009 from US$86.80 in 2008. The average market price of nickel per ton trading on the London Metal Exchange decreased by 30.6% to US$14,655 in 2009 from US$21,111 in 2008. The impact from these factors was partially offset by a 6.9% increase in our depreciation and amortization expenses included in cost of goods sold to Won 2,429 billion in 2009 from Won 2,273 billion in 2008 primarily due to an increase in capital investments in our facilities in recent years for production of higher value-added products.

Gross Profit

Gross profit in 2009 decreased by 36.6% to Won 5,818 billion from Won 9,180 billion in 2008, and gross margin in 2009 decreased to 15.8% from 22.0% in 2008 as the 11.7% decrease in sales outpaced a 4.7% decrease in cost of goods sold discussed above. The decrease in sales in 2009 outpaced the decrease in cost of goods sold as the impact from decreases in sales prices of our steel products resulting from weak global market conditions was greater than the cost savings resulting from decreases in the average prices of key raw materials.

Selling and Administrative Expenses

Our selling and administrative expenses decreased by 2.8% in 2009 to Won 1,949 billion from Won 2,006 billion in 2008. The decrease in selling and administrative expenses resulted primarily from decreases in transportation and storage expenses, the impact of which was partially offset by increases in fees and charges and stock compensation expenses. Our transportation and storage expenses in 2009 decreased by 17.0% to Won 648 billion from Won 781 billion in 2008 primarily resulting from a decrease in oil prices in 2009 compared to 2008. Fees and charges, which include certain administrative fees and professional service fees, increased by 27.4% to Won 158 billion in 2009 from Won 124 billion in 2008 primarily as a result of increases in service fees and expenses incurred by our subsidiaries as well as increases in management and tax consulting expenses in 2009. We recognized stock compensation expenses, which are categorized under “others,” of Won 36 billion in 2009 primarily as a result of an increase in the benchmark average stock price used to calculate stock compensation in 2009 compared to 2008. We did not recognize any stock compensation expense in 2008.

Operating Income

Due to the factors described above, our operating income decreased by 46.1% in 2009 to Won 3,868 billion from Won 7,174 billion in 2008. Operating margin decreased to 10.5% in 2009 from 17.2% in 2008.

52

Non-operating Income (Expenses), Net

Our net non-operating expenses decreased by 88.0% to Won 129 billion in 2009 from Won 1,078 billion in 2008 primarily due to by net gain on foreign currency translation in 2009 compared to net loss on foreign currency translation in 2008, net gain on derivative transactions in 2009 compared to net loss on derivative transactions in 2008, an increase in gain on disposal of property, plant and equipment and the disposition of other long-term assets by POSCO E&C, the aggregate impact of which was partially offset by increases in interest expense and loss on impairment of investments and net loss on valuation of derivatives in 2009 compared to net gain on valuation of derivatives in 2008. Such factors were principally attributable to the following:

•     We recognized net gain on foreign currency translation of Won 436 billion in 2009 compared to net loss on foreign currency translation of Won 811 billion in 2008 and net gain on derivative transactions of Won 10 billion in 2009 compared to net loss on derivative transactions of Won 62 billion in 2008 as the market average exchange rate of the Won against the U.S. dollar depreciated from Won 938.2 to US$1.00 as of December 31, 2007 to Won 1,257.5 to US$1.00 as of December 31, 2008 but appreciated to Won 1,167.6 to US$1.00 as of December 31, 2009.

•     Our gain on disposal of property, plant and equipment in 2009 increased by 485.7% to Won 82 billion from Won 14 billion in 2008 primarily due to the gain from disposition of a research center by POSCO E&C in 2009.

•     Our gain on disposal of other long-term assets increased by 387.5% to Won 234 billion in 2009 from Won 48 billion in 2008 primarily due to the disposition of shares of POS-Plaza in Shanghai by POSCO E&C.

These factors were partially offset by the following:

•     Our interest expense in 2009 increased by 54.2% to Won 532 billion from Won 345 billion in 2008 primarily due to an increase in our long-term debt, which was offset in part by a general decrease in interest rates in Korea in 2009.

•     Our loss on impairment of investments in 2009 increased by 136.4% to Won 286 billion from Won 121 billion in 2008 primarily due to an impairment loss of Won 209 billion as a result of objective evidence that indicated an impairment in our investment in LG Powercom.

•     We recorded net loss on valuation of derivatives of Won 43 billion in 2009 compared to net gain on valuation of derivatives of Won 58 billion in 2008 as the Won fluctuated against the U.S. dollar as described above.

Income Tax Expense

Income tax expense decreased by 69.1% to Won 536 billion in 2009 from Won 1,734 billion in 2008 primarily due to a 38.7% increase in income before income tax expense and net income (loss) of consolidated subsidiaries before acquisition as well as an increase in tax credit to Won 371 billion in 2009 from Won 168 billion in 2008 and a tax refund of Won 140 billion in 2009 representing additional tax payments made in the prior year. Our effective tax rate was 14.3% in 2009 compared to 28.4% in 2008. The statutory income tax rate applicable to us, including resident tax surcharges, decreased to 24.2% in 2009 from 27.5% in 2008.

Net Income

Due to the factors described above, our income decreased by 25.5% to Won 3,242 billion in 2009 from Won 4,350 billion in 2008.

53

Segment Results — Steel

Our sales to external customers decreased by 10.3% to Won 34,503 billion in 2009 from Won 38,448 billion in 2008. After adjusting for inter-segment transactions, our net sales decreased by 10.9% to Won 28,413 billion in 2009 from Won 31,901 billion in 2008, primarily as a result of a decrease in our sales volume of steel products and a decrease in the average unit sales price per ton of steel products sold by us.

Operating income decreased by 51.5% to Won 3,217 billion in 2009 from Won 6,629 billion in 2008, as the 10.9% decrease in the segment’s net sales more than outpaced decreases in cost of goods sold and selling and administrative expenses, primarily due to reasons discussed above. Operating margin, which is operating income as a percentage of total sales prior to adjusting for inter-company sales, decreased to 9.3% in 2009 from 17.2% in 2008. Depreciation and amortization increased by 9.1% to Won 2,369 billion in 2009 from Won 2,171 billion in 2008, primarily due to an increase in capital investment in our facilities in recent years for production of higher value-added products.

Segment Results — Engineering and Construction

Our sales to external customers increased by 40.4% to Won 7,760 billion in 2009 from Won 5,528 billion in 2008. After adjusting for inter-segment transactions, our net sales increased by 6.4% to Won 3,908 billion in 2009 from Won 3,672 billion in 2008, primarily due to an increase in sales from POSCO E&C’s overseas operations from its thermal power plant construction projects in Chile.

Operating income increased by 21.8% to Won 346 billion in 2009 from Won 284 billion in 2008, primarily due to an increase in the volume of POSCO E&C’s construction projects. The segment’s operating margin, which is operating income as a percentage of total sales prior to adjusting for inter-company sales, decreased to 4.5% in 2009 from 5.1% in 2008 as the market conditions in the domestic construction industry weakened in 2009, resulting in an increase in competition.

Segment Results — Trading

Our sales to external customers decreased by 27.2% to Won 4,120 billion in 2009 from Won 5,657 billion in 2008, primarily due to a decrease in the trading volume as well as the average unit sales price per ton of steel products sold. After adjusting for inter-segment transactions, our net sales decreased by 30.1% to Won 2,982 billion in 2009 from Won 4,265 billion in 2008.

Operating income decreased by 32.7% to Won 33 billion in 2009 from Won 49 billion in 2008, and the segment’s operating margin, which is operating income as a percentage of total sales prior to adjusting for inter-company sales, decreased to 0.8% in 2009 from 0.9% in 2008.

Segment Results — Others

The “others” segment includes power generation, LNG production, network and system integration, logistics and magnesium coil and sheet production. Our sales to external customers decreased by 8.8% to Won 3,420 billion in 2009 from Won 3,749 billion in 2008. Our sales decreased in 2009 primarily due to a decrease in revenues of POSCO Power Corporation resulting from lower production utilization rate, the impact of which was offset in part by an increase in revenues of POSCO Refractories & Environment Co., Ltd. After adjusting for inter-segment transactions, our net sales decreased by 18.5% to Won 1,552 billion in 2009 from Won 1,905 billion in 2008.

Operating income decreased by 45.1% to Won 268 billion in 2009 from Won 488 billion in 2008. The segment’s operating margin, which is operating income as a percentage of total sales prior to adjusting for inter-company sales, decreased to 7.8% in 2009 from 13.0% in 2008. Our operating income decreased in 2009 primarily due to a decrease in operating income of POSCON Co., Ltd. Depreciation and amortization increased by 37.3% to Won 206 billion in 2009 from Won 150 billion in

54

2008, primarily due to an increase in capital investment by POSCO Power Corporation, including completion of a fuel cell manufacturing plant with an annual production capacity of 50 megawatts in Pohang in 2008.

Capital Requirements

Historically, uses of cash consisted principally of purchases of property, plant and equipment and other assets and repayments of outstanding debt and payments of dividends. From time to time, we have also engaged in acquisition of treasury shares.

Net cash used in investing activities was Won 5,803 billion in 2008, Won 9,717 billion in 2009 and Won 6,890 billion in 2010. These amounts included acquisition of property, plant and equipment of Won 4,093 billion in 2008, Won 6,407 billion in 2009 and Won 5,896 billion in 2010. We plan to increase our capital expenditures in 2011, which we may adjust on an on-going basis subject to market demand for our products, the production outlook of the global steel industry and global economic conditions in general. We may delay or not implement some of our current capital expenditure plans based on our assessment of such market conditions. We recorded net acquisition of short-term financial instruments of Won 53 billion in 2008 and Won 4,012 billion in 2009 and net disposal of short-term financial instruments of Won 2,880 billion in 2010. We also recorded net acquisition ofavailable-for-sale securities of Won 1,331 billion in 2008, Won 352 billion in 2009 and Won 386 billion in 2010.

In our financing activities, we used cash of Won 9,043 billion in 2008, Won 5,836 billion in 2009 and Won 3,325 billion in 2010 for repayments of short-term borrowings, and Won 861 billion in 2008, Won 1,349 billion in 2009 and Won 789 billion in 2010 for repayments of outstanding long-term debt.

We paid dividends on common stock in the amount of Won 755 billion in 2008, Won 689 billion in 2009 and Won 693 billion in 2010.

In recent years, we have also selectively considered various opportunities to acquire or invest in companies that may complement our businesses, as well as invest in overseas resources development projects. For example, on September 20, 2010, we acquired a 68.15% interest in Daewoo International for Won 3.37 trillion. We submitted a letter of intent to Asiana Airlines Inc. and Daewoo E&C Co., Ltd. on March 4, 2011 and our Board of Directors decided on May 13, 2011 to participate in the final bid for the acquisition of a controlling stake in Korea Express Co., Ltd., a leading logistics company in Korea. Korea Express is being sold in an auction process and the preferred bidder is expected to be selected in the second quarter of 2011. We may require additional capital for such acquisitions or entering into other strategic relationships. Other than capital required for such activities, we anticipate that capital expenditures, repayments of outstanding debt and payments of cash dividends will represent the most significant uses of funds for the next several years.

55

Payments of contractual obligations and commitments will also require considerable resources. In our ordinary course of business, we routinely enter into commercial commitments for various aspects of our operations, as well as issue guarantees for our related companies’ indebtedness. As of December 31, 2010, we issued guarantees of Won 6,456 billion for the repayment of loans of related companies and others. See note 17 of notes to our Consolidated Financial Statements. The following table sets forth the amount of long-term debt, capital lease and operating lease obligations as of December 31, 2010.

	Payments Due by Period
			Less Than						After
Contractual Obligations	Total		1 Year		1 to 3 Years		4 to 5 Years		5 Years
	(In billions of Won)
Long-term debt obligations (a)	W	14,176	W	3,487	W	5,183	W	3,263	W	2,243

Accrued severance benefits (f)		1,127		49		152		201		725
Total	W	74,022	W	15,688	W	25,135	W	18,468	W	14,731

(a)	Includes the current portion and premium on bond redemption but excludes amortization of discount on debentures and issuance costs.
(b)	As of December 31, 2010, a portion of our long-term debt carried variable interest rates. We used the interest rate in effect as of December 31, 2010 in calculating the interest payments on long-term debt for the periods indicated.
(c)	We entered into a capital lease contract with Ilshin Shipping Co., Ltd. for a vessel for transporting plates and other products.
(d)	We acquired certain tools and equipment under operating lease agreements with Macquarie Capital Korea Co., Ltd. and others.
(e)	Our purchase obligations include long-term contracts to purchase iron ore, coal, LNG and other raw materials. These contracts generally have terms of three to ten years and provide for periodic price adjustments to then-market prices. As of December 31, 2010, 308 million tons of iron ore and 52 million tons of coal remained to be purchased under long-term contracts. In addition, we entered into an agreement with Tangguh LNG Consortium in Indonesia to purchase 550 thousand tons of LNG annually for 20 years commencing in August 2005. The purchase price under the agreement with Tangguh LNG Consortium is variable based on the monthly standard oil price (as represented by the Japan Customs-cleared Crude Price), subject to a ceiling. We used the market price in effect as of December 31, 2010 in calculating the iron ore, coal and LNG purchase obligations described above for the periods indicated.
(f)	Represents, as of December 31, 2010, the expected amount of severance benefits that we will be required to pay under applicable Korean law to all of our employees when they reach their normal retirement age. The amounts were determined based on the employees’ current salary rates and the number of service years that will be accumulated upon their retirement. These amounts do not include amounts that may be paid to employees who cease to work at the company before their normal retirement age.

Capital Resources

We have traditionally met our working capital and other capital requirements principally from cash provided by operations, while raising the remainder of our requirements primarily through long-term debt and short-term borrowings. We expect that these sources will continue to be our principal sources of cash in the future. From time to time, we may also generate cash through sale of treasury shares.

Our net cash provided by operating activities was Won 3,687 billion in 2008, Won 8,633 billion in 2009 and Won 2,025 billion in 2010. Our net cash provided by operating activities increased by 134.1%, or Won 4,946 billion, to Won 8,633 billion in 2009 compared to Won 3,687 billion in 2008. Our sales decreased by 11.7%, or Won 4,888 billion, primarily reflecting a 7.4% decrease in the sales volume of our steel products as well as a 5.2% decrease in the average unit sales price per ton of our steel products, as discussed above, which decreased gross cash inflow from our sales activities. In addition, cash used for payment of income tax in 2009 increased significantly due to an increase in

56

our income level in 2008. However, our overall net cash provided by operating activities increased significantly in 2009 compared to 2008 as we focused on decreasing our inventory level. Decrease in inventories in 2009 primarily reflected a decrease in the volume of inventories due to a reduction of our crude steel production in the first quarter of 2009 as well as a decrease in the price of steel products in 2009. In response to weak demand from certain segments of our customers in industries adversely impacted by deteriorating global economic conditions in the first quarter of 2009, such as the domestic automotive and construction industries, we reduced our crude steel production in the first quarter of 2009. In addition, we have taken the following steps in 2009 to reduce our inventory level:

•     setting inventory targets for each product type and segment;

•     monitoring sales activities through our newly-established special sales committee;

•     focusing on reducing inventories older than 30 days; and

•     setting up a system to report inventories older than 30 days to a responsible sales manager.

Our trade accounts and notes receivables also decreased in 2009, which typically occur in an economic recovery. We have taken the following steps in 2009 to reduce our accounts and notes receivable level:

•     increasing management oversight on the accounts receivable turnover ratio;

•     strengthening efforts to collect from delinquent customers and maintaining adequate level of collateral; and

•     converting to cash settlement for customers with high risk of insolvency.

Our net cash provided by operating activities decreased by 76.5% to Won 2,025 billion in 2010 from Won 8,633 billion in 2009. The sales volume of our steel products increased by 24.5% in such periods as discussed above, which increased gross cash inflow from our sales activities. However, our overall net cash provided by operating activities decreased by 76.5% as an increase in the price of raw materials in 2010 led to an increase in the inventory level and a delay in recoupment of cash used in production activities, including purchase of raw materials. Our inventory level increased to Won 9,803 billion as of December 31, 2010 from Won 5,153 billion as of December 31, 2009. Such developments resulted in an overall decrease of net cash provided by operating activities in 2010 compared to 2009.

Net proceeds from short-term borrowings, after deducting for repayment of short-term borrowings, were Won 1,191 billion in 2008, Won (8) billion in 2009 and Won 1,969 billion in 2010. Net proceeds from long-term debt, after deducting for repayment of long-term debt and current portion of long-term debt, were Won 2,594 billion in 2008, Won 1,347 billion in 2009 and Won 3,899 billion in 2010. On April 14, 2011, we also issued $700 million of unsecured senior notes due 2021. Total long-term debt, including current portion but excluding discount on debentures issued, were Won 7,666 billion as of December 31, 2008, Won 9,017 billion as of December 31, 2009 and Won 14,039 billion as of December 31, 2010, and total short-term borrowings were Won 3,254 billion as of December 31, 2008, Won 3,226 billion as of December 31, 2009 and Won 5,838 billion as of December 31, 2010. We periodically increase our short-term borrowings and adjust our long-term debt financing levels depending on changes in our capital requirements. We also generated cash of Won 407 billion in 2007, Won 365 billion in 2008 and Won 249 billion in 2009 from the sale of our treasury shares.

We believe that we have sufficient working capital available to us for our current requirements and that we have a variety of alternatives available to us to satisfy our financial requirements to the extent that they are not met by funds generated by operations, including the issuance of debt and equity securities and bank borrowings denominated in Won and various foreign currencies. However, our ability to rely on some of these alternatives could be affected by factors such as the liquidity of the

57

Korean and the global financial markets, prevailing interest rates, our credit rating and the Government’s policies regarding Won currency and foreign currency borrowings.

Liquidity

Our liquidity is affected by exchange rate fluctuations. See “— Overview — Exchange Rate Fluctuations.” Approximately 35.6% of our sales in 2008, 38.9% of our sales in 2009 and 49.3% of our sales in 2010 were denominated in foreign currencies. In 2010, approximately 86% of such sales were denominated in Dollars and approximately 14% in Yen. As of December 31, 2010, approximately 53.5% of our long-term debt (excluding discounts on debentures issued and including current portion) was denominated in foreign currencies, principally in Dollars and Yen.

Our liquidity is also affected by our construction expenditures and raw materials purchases. Cash used for acquisitions of property, plant and equipment was Won 4,093 billion in 2008, Won 6,407 billion in 2009 and Won 5,896 billion in 2010. We have entered into several long-term contracts to purchase iron ore, coal and other raw materials. The long-term contracts generally have terms of three to ten years and provide for periodic price adjustments to then-market prices. As of December 31, 2010, 308 million tons of iron ore and 52 million tons of coal remained to be purchased under long-term contracts. We may face unanticipated increases in capital expenditures and raw materials purchases. There can be no assurance that we will be able to secure funds on satisfactory terms from financial institutions or other sources that are sufficient for our unanticipated needs.

We had a working capital (current assets minus current liabilities) of Won 11,188 billion as of December 31, 2008, Won 11,359 billion as of December 31, 2009 and Won 10,014 billion as of December 31, 2010. POSCO had unused credit lines of Won 1,279 billion out of total available credit lines of Won 2,619 billion as of December 31, 2010. We have not had, and do not believe that we will have, difficulty gaining access to short-term financing sufficient to meet our current requirements.

Capital Expenditures and Capacity Expansion

Our capital expenditures amounted to Won 4,093 billion in 2008, Won 6,407 billion in 2009 and Won 5,896 billion in 2010. We currently plan to increase our capital expenditures in 2011, which we may adjust on an on-going basis subject to market demand for our products, the production outlook of the global steel industry and global economic conditions in general. We may delay or not implement some of our current capital expenditure plans based on our assessment of such market conditions.

Our current plan for capital investment in production facilities emphasizes capacity rationalization, increased production of higher value-added products and improvements in the efficiency of older facilities in order to reduce operating costs. The following table sets out the major items of our capital expenditures as of December 31, 2010:

			Estimated
			Remaining Cost of
			Completion
	Expected	Total Cost	as of December 31,
Project	Completion Date	of Project	2010
	(In billions of Won)

U.S. GAAP Reconciliation

Our consolidated financial statements are prepared in accordance with Korean GAAP, which differ in significant respects from U.S. GAAP. For a discussion of the significant differences between Korean GAAP and U.S. GAAP, see Note 32 of Notes to Consolidated Financial Statements.

Our net income in accordance with U.S. GAAP was Won 4,377 billion in 2010 compared to Won 3,609 billion in 2009 and Won 4,084 billion in 2008 primarily due to the factors discussed in “— Operating Results.” Our net income under U.S. GAAP of Won 4,377 billion in 2010 is 3.8% higher than our net income under Korean GAAP of Won 4,218 billion. See Note 32(a) of Notes to Consolidated Financial Statements.

Item 5.C.  Research and Development, Patents and Licenses, Etc.

We maintain a research and development program to carry out basic research and applied technology development activities. Our technology development department works closely with the Pohang University of Science & Technology, Korea’s first research-oriented college founded by us in 1986, and the Research Institute of Industrial Science and Technology, Korea’s first private comprehensive research institute founded by us in 1987. As of December 31, 2010, Pohang University of Science & Technology and the Research Institute of Industrial Science and Technology employed a total of approximately 977 researchers.

In 1994, we founded the POSCO Technical Research Laboratory to carry out applied research and technology development activities. As of December 31, 2010, the Technical Research Laboratory employed a total of 434 researchers.

We recorded research and development expenses of Won 361 billion as cost of goods sold in 2008, Won 368 billion in 2009 and Won 395 billion in 2010, as well as research and development expenses of Won 95 billion as selling and administrative expenses in 2008, Won 84 billion in 2009 and Won 142 billion in 2010.

Our research and development program has filed over twenty-nine thousand industrial rights applications relating to steel-making technology, approximately one-fourth of which were registered as of December 31, 2010, and has successfully applied many of these to the improvement of our manufacturing process.

Item 5.D.  Trend Information

These matters are discussed under Item 5.A. and Item 5.B. above where relevant.

Item 5.E.  Off-balance Sheet Arrangements

As of December 31, 2008, 2009 and 2010, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Item 6.B.  Compensation

Compensation of Directors and Officers

Salaries and bonuses for Inside Directors and salaries for Directors are paid in accordance with standards decided by the board of directors within the limitation of directors remuneration approved by the annual general meeting of shareholders. In addition, executive officers’ compensation is paid in accordance with standards decided by the board of directors. The aggregate compensation paid and accrued to all Directors and executive officers was approximately Won 29.9 billion in 2010 and the aggregate amount set aside or accrued by us to provide pension and retirement benefits to such persons was Won 5.7 billion in 2010.

We have also granted stock options to some of our Directors and executive officers. See “— Item 6.E. Share Ownership” for a list of stock options granted to our Directors and executive officers. At the annual shareholders’ meeting held in February 2006 our shareholders elected to terminate the stock option program. Stock options granted prior to this meeting remain valid and outstanding pursuant to the articles of incorporation in effect at the time of the issuance of the stock option.

Item 6.C.  Board Practices

Director Candidate Recommendation Committee

The Director Candidate Recommendation Committee is composed of three Outside Directors, Lee, Young-Sun (committee chair), Nam, Yong, Byun, Dae-Gyu and one Inside Director, Choi, Jong-Tae. The Director Candidate Recommendation Committee reviews the qualifications of potential candidates and proposes nominees to serve on our board of directors as an Outside Director. Any shareholder holding our outstanding shares with voting rights may suggest candidates for Outside Directors to the Director Candidate Recommendation Committee.

Evaluation and Compensation Committee

The Evaluation and Compensation Committee is composed of four Outside Directors, Kim, Byung-Ki (committee chair), Han, Joon-Ho, Lee, Chang-Hee and Byun, Dae-Gyu. The Evaluation and Compensation Committee’s primary responsibilities include establishing evaluation procedures and compensation plans for executive officers and taking necessary measures to execute such plans.

Finance and Operation Committee

The Finance and Operation Committee is composed of three Outside Directors, Han, Joon-Ho (committee chair), Lee, Young-Sun, Nam, Yong and two Inside Directors, Park, Han-Yong and Oh, Chang-Kwan. This committee is an operational committee that oversees decisions with respect to finance and operational matters, including making assessments with respect to potential capital investments and evaluating prospective capital-raising activities.

63

Executive Management Committee

The Executive Management Committee is composed of five Inside Directors: Chung, Joon-Yang (committee chair), Choi, Jong-Tae, Park, Han-Yong, Oh, Chang-Kwan and Kim, Jin-Il. This committee oversees decisions with respect to our operational and management matters, including review of management’s proposals of new strategic initiatives, as well as deliberation over critical internal matters related to organization structure and development of personnel.

Audit Committee

Under Korean law and our articles of incorporation, we are required to have an Audit Committee. The Audit Committee may be composed of three or more directors; all members of the Audit Committee must be Outside Directors. Audit Committee members must also meet the applicable independence criteria set forth under the rules and regulations of the Sarbanes-Oxley Act of 2002. Members of the Audit Committee are elected by the shareholders at the ordinary general meeting of shareholders. We currently have an Audit Committee composed of three Outside Directors. Members of our Audit Committee are Lee, Chang-Hee (committee chair), Kim, Byung-Ki and Park, Sang-Kil.

The duties of the Audit Committee include:

•     engaging independent auditors;

•     approving independent audit fees;

•     approving audit and non-audit services;

•     reviewing annual financial statements;

•     reviewing audit results and reports, including management comments and recommendations;

•     reviewing our system of controls and policies, including those covering conflicts of interest and business ethics; and

•     examining improprieties or suspected improprieties.

In addition, in connection with general meetings of stockholders, the committee examines the agenda for, and financial statements and other reports to be submitted by, the board of directors at each general meeting of stockholders. Our internal and external auditors report directly to the Audit Committee. The committee holds regular meetings at least once each quarter, and more frequently as needed.

Related Party Transactions Committee

The Related Party Transaction Committee is composed of three Outside Directors, Lee, Chang-Hee (committee chair), Kim, Byung-Ki and Park, Sang-Kil. This committee reviews related party and other internal transactions and ensures compliance with the Monopoly Regulation and Fair Trade Act.

Item 6.D.  Employees

As of December 31, 2010, we had 33,557 employees, including 17,148 persons employed by our subsidiaries, almost all of whom were employed within Korea. Of the total number of employees, approximately 80% are technicians and skilled laborers and 20% are administrative staff. We use subcontractors for maintenance, cleaning and transport activities. We had 29,811 employees, including 13,295 persons employed by our subsidiaries, as of December 31, 2009, and 29,730 employees, including 13,023 persons employed by our subsidiaries, as of December 31, 2008. To improve operational efficiency and increase labor productivity, we plan to reduce the number of our employees in future years through natural attrition. However, we expect the number of persons employed by our subsidiaries in growth industries to increase in the future.

64

We consider our relations with our work force to be excellent. We have never experienced a work stoppage or strike. Wages of our employees are among the highest of manufacturing companies in Korea. In addition to a base monthly wage, employees receive periodic bonuses and allowances. Base wages are determined annually following consultation between the management and employee representatives, who are currently elected outside the framework of the POSCO labor union. A labor union was formed by our employees in June 1988. Union membership peaked at 19,026 employees at the beginning of 1991, but has steadily declined since then. As of December 31, 2010, only 13 of our employees were members of the POSCO labor union.

In accordance with the National Pension Act of Korea, we contribute an amount equal to 4.5% of an employee’s standard monthly wages, and each employee contributes 4.5% of his or her standard monthly wages, into his or her personal pension account. Our employees, including executive officers as well as non-executive employees, are subject to a pension insurance system, under which we make monthly contributions to the pension accounts of the employees, and upon retirement, such employees are paid from their pension accounts. Prior to 2011, our executive and non-executive employees were subject to a lump-sum severance payment system, under which they were entitled to receive a lump-sum severance payment upon termination of their employment, based on their length of service and salary level at the time of termination. Starting in 2011, in accordance with the Korean Employee Retirement Income Security Act, we replaced such lump-sum severance payment system with our current pension insurance system in the form of either a defined benefit plan or a defined contribution plan, with a total unfunded portion of Won 981 billion as of December 31, 2010. Our employees have the option of choosing either the defined benefit plan or the defined contribution plan. Lump-sum severance amounts previously accrued prior to our adoption of the current pension insurance system continue to remain payable. We also provide a wide range of fringe benefits to our employees, including housing, housing loans, company-provided hospitals and schools, a company-sponsored pension program, an employee welfare fund, industrial disaster insurance, and cultural and athletic facilities.

As of December 31, 2010, our employees owned, through our employee stock ownership association, approximately 0.01% of our common stock in their association accounts and 2.54% of our common stock in their employee accounts.

Item 6.E.  Share Ownership

Common Stock

The persons who are currently our Directors or executive officers held, as a group, 19,423 common shares as of June 23, 2011, the most recent practicable date for which this information is available. The table below shows the ownership of our common shares by our Directors and executive officers.

Stock Options

The following table sets forth information regarding the stock options we have granted to our current Directors and executive officers as of March 31, 2011. With respect to the options granted, we may elect either to issue shares of common stock, distribute treasury stock or to pay in cash the difference between the exercise and the market price at the date of exercise. The options may be exercised by a person who has continued employment with POSCO for two or more years from the date on which the options are granted. Expiration date of options is seven years from the date on which the options are granted. All of the stock options below relate to our common stock.

At the annual shareholders’ meeting held in February 2006, our shareholders elected to terminate the stock option program. Stock options granted prior to this meeting remain valid and outstanding pursuant to the articles of incorporation in effect at the time of the issuance of the stock option.

The Korean Securities Market

On January 27, 2005, the Korea Exchange was established pursuant to the Korea Securities and Futures Exchange Act by consolidating the Korea Stock Exchange, the Korea Futures Exchange, the KOSDAQ Stock Market, Inc., or the KOSDAQ, and the KOSDAQ Committee of the Korea Securities Dealers Association, which had formerly managed the KOSDAQ. There are three different markets operated by the Korea Exchange: the KRX KOSPI Market, the KRX KOSDAQ Market, and the KRX Derivatives Market. The Korea Exchange has two trading floors located in Seoul, one for the KRX KOSPI Market and one for the KRX KOSDAQ Market, and one trading floor in Busan for the KRX Derivatives Market. The Korea Exchange is a limited liability company, the shares of which are held by (i) investment brokers and investment dealers that were formerly members of the Korea Futures Exchange or the Korea Stock Exchange and (ii) the stockholders of the KOSDAQ. Currently, the Korea Exchange is the only stock exchange in Korea and is operated by membership, having as its members most of the Korean investment brokers and investment dealers and some Korean branches of foreign investment brokers and investment dealers.

According to data published by the Korea Exchange, as of December 31, 2010, the aggregate market value of equity securities listed on the KRX KOSPI Market and the KRX KOSDAQ Market was approximately Won 1,239 trillion, and the average daily trading volume of equity securities for 2010 was approximately 1,024 million shares with an average transaction value of Won 7,544 billion The

71

Korea Exchange has the power in some circumstances to suspend trading in the shares of a given company or to de-list a security pursuant to the Regulation on Listing on the Korea Exchange. The Korea Exchange also restricts share price movements. All listed companies are required to file accounting reports annually, semi-annually and quarterly and to release immediately all information that may affect trading in a security.

The Government has in the past exerted, and continues to exert, substantial influence over many aspects of the private sector business community that can have the intention or effect of depressing or boosting the market. In the past, the Government has informally both encouraged and restricted the declaration and payment of dividends, induced mergers to reduce what it considers excess capacity in a particular industry and induced private companies to offer publicly their securities.

The Korea Exchange publishes the Korea Composite Stock Price Index, or KOSPI, every ten seconds, which is an index of all equity securities listed on the Korea Exchange. On January 1, 1983, the method of computing KOSPI was changed from the Dow Jones method to the aggregate value method. In the new method, the market capitalizations of all listed companies are aggregated, subject to certain adjustments, and this aggregate is expressed as a percentage of the aggregate market capitalization of all listed companies as of the base date, January 4, 1980.

Movements in KOSPI are set out in the following table together with the associated dividend yields and price earnings ratios.

(1)	Dividend yields are based on daily figures. Before 1983, dividend yields were calculated at the end of each month. Dividend yields after January 3, 1984 include cash dividends only.
(2)	Starting in April 2000, dividend yield and price earnings ratio are calculated based on KOSPI 200, an index of 200 equity securities listed on the KRX KOSPI Market. Starting in April 2000, KOSPI 200 excludes classified companies, companies which did not submit annual reports to the KRX KOSPI Market, and companies which received qualified opinion from external auditors.
(3)	The price earnings ratio is based on figures for companies that record a profit in the preceding year.

Shares are quoted “ex-dividend” on the first trading day of the relevant company’s accounting period. Since the calendar year is the accounting period for the majority of listed companies, this may account for the drop in KOSPI between its closing level at the end of one calendar year and its opening level at the beginning of the following calendar year.

With certain exceptions, principally to take account of a share being quoted “ex-dividend” and “ex-rights,” permitted upward and downward movements in share prices of any category of shares on any day are limited under the rules of the Korea Exchange to 15% of the previous day’s closing price of the shares, rounded down as set out below:

	Rounded Down
Previous Day’s Closing Price (Won)	to (Won)
Less than 5,000		5
5,000 to less than 10,000		10
10,000 to less than 50,000		50
50,000 to less than 100,000		100
100,000 to less than 500,000		500
500,000 or more		1,000

As a consequence, if a particular closing price is the same as the price set by the fluctuation limit, the closing price may not reflect the price at which persons would have been prepared, or would be prepared to continue, if so permitted, to buy and sell shares. Orders are executed on an auction system with priority rules to deal with competing bids and offers.

Due to deregulation of restrictions on brokerage commission rates, the brokerage commission rate on equity securities transactions may be determined by the parties, subject to commission schedules being filed with the Korea Exchange by the financial investment companies with a brokerage license. In addition, a securities transaction tax of 0.15% of the sales price will generally be imposed on the transfer of shares or certain securities representing rights to subscribe for shares. An agricultural and fishery special surtax of 0.15% of the sales prices will also be imposed on transfer of these shares and securities on the Korea Exchange. See “Item 10. Additional Information — Item 10.E. Taxation — Korean Taxation.”

The Korean securities markets are principally regulated by the Financial Services Commission and under the regulations set forth in the Financial Investment Services and Capital Markets Act. In July 2007, the National Assembly of Korea enacted the Financial Investment Services and Capital Markets Act. The Financial Investment Services and Capital Markets Act, which came into effect on February 4, 2009, comprehensively regulates the Korean capital markets, the financial investment business (including collective investment businesses and trust businesses) and financial investment products (such as securities and derivatives). The FSCMA imposes restrictions on insider trading and price manipulation, requires specified information to be made available by listed companies to investors and establishes rules regarding margin trading, proxy solicitation, takeover bids, acquisition of treasury shares and reporting requirements for shareholders holding substantial interests. The FSCMA regulates the operation and monitoring of the securities and derivatives markets.

Protection of Customer’s Interest in Case of Insolvency of Investment Brokers or Investment Dealers

Under Korean law, the relationship between a customer and an investment broker or an investment dealer in connection with a securities sell or buy order is deemed to be a consignment and the securities acquired by a consignment agent (i.e., the investment broker or the investment dealer) through such sell or buy order are regarded as belonging to the customer in so far as the customer and the consignment agent’s creditors are concerned. Therefore, in the event of a bankruptcy or reorganization procedure involving an investment broker or an investment dealer, the customer of the investment broker or the investment dealer is entitled to the proceeds of the securities sold by the investment broker or the investment dealer.

When a customer places a sell order with an investment broker or an investment dealer that is not a member of the KRX KOSPI Market or the KRX KOSDAQ Market and this investment broker or investment dealer places a sell order with another investment broker or investment dealer that is a member of the KRX KOSPI Market or the KRX KOSDAQ Market, the customer is still entitled to the proceeds of the securities sold and received by the non- member company from the member company regardless of the bankruptcy or reorganization of the non-member company.

Under the Financial Investment Services and Capital Markets Act, the Korea Exchange is obliged to indemnify any loss or damage incurred by a counterparty as a result of a breach by members of the KRX KOSPI Market or the KRX KOSDAQ Market. If an investment broker or an investment dealer that is a member of the KRX KOSPI Market or the KRX KOSDAQ Market breaches its obligation in connection with a buy order, the Korea Exchange is obliged to pay the purchase price on behalf of the breaching member. Therefore, the customer can acquire the securities that have been ordered to be purchased by the breaching member.

When a customer places a buy order with a non-member company and the non-member company places a buy order with a member company, the customer has the legal right to the securities received by the non-member company from the member company because the purchased securities are regarded as belonging to the customer in so far as the customer and the non-member company’s creditors are concerned.

As the cash deposited with an investment broker or an investment dealer is regarded as belonging to the investment broker or investment dealer, which is liable to return the same at the request of its customer, the customer cannot take back deposited cash from the investment broker or the investment dealer if a bankruptcy or rehabilitation procedure is instituted against the investment broker or the investment dealer and, therefore, can suffer from loss or damage as a result. However, in case of the investment broker or the investment dealer’s bankruptcy, liquidation, cancellation of investment broker or investment dealer license or other insolvency events, the Depositor Protection Act provides that the Korea Deposit Insurance Corporation will, upon the request of the investors, pay each investor up to a total of Won 50 million, which shall represent both actual cash deposited and any interest accrued thereon. Pursuant to the Financial Investment Services and Capital Markets Act, as amended, investment brokers or investment dealers are required to deposit the cash received from its customers at the securities finance company established pursuant to the Financial Investment Services and Capital Markets Act. Set-off or attachment of cash deposits by investment brokers or investment dealers is prohibited. The premiums related to this insurance are paid by investment brokers or investment dealers.

Clearance and Settlement

The settlement of trades on the Korea Exchange is required to be handled by a settlement agency of the Korea Exchange. The Korea Securities Depository is the institution commissioned by the Korea Exchange to handle all such settlement of trades. The settlement of trades on the Korea Exchange takes place through a clearance and settlement procedure. The Korea Exchange has adopted the multilateral netting system and carries out the clearance of the trades by netting the sales

75

and purchases of each Korea Securities Depository participant. The Korea Exchange is required to provide the daily net settlement results of the trades to the Korea Securities Depository one business day after the day of the sale and purchase contract. The Korea Securities Depository then handles settlement of the securities and the funds based on the information received from the Korea Exchange. The securities are settled through book-entry changes in the accounts of Korea Securities Depository participants and the funds are settled by transfer to an account at a bank designated by the Korea Securities Depository. Settlement of trades is generally required to take place on the third day following the day of the sale and purchase contract.

Item 10.  Additional Information

Item 10.A.  Share Capital

Currently, our authorized share capital is 200,000,000 shares, which consists of shares of common stock, par value Won 5,000 per share (“Common Shares”) and shares of non-voting stock, par value Won 5,000 per share (“Non-Voting Shares”). Common Shares and Non-Voting Shares together are referred to as “Shares.” Under our articles of incorporation, we are authorized to issue Non-Voting Shares up to the limit prescribed by applicable law, the aggregate of which currently is one-half of our total issued and outstanding capital stock. As of December 31, 2010, 87,186,835 Common Shares were issued, of which 7,792,072 shares were held by us in treasury and an additional 2,361,885 shares were held by our treasury stock fund. We have never issued any Non-Voting Shares. All of the issued and outstanding Common Shares are fully-paid and non-assessable and are in registered form. We issue share certificates in denominations of 1, 3, 4, 5, 10, 50, 100, 500, 1,000 and 10,000 shares.

Item 10.B.  Memorandum and Articles of Association

This section provides information relating to our capital stock, including brief summaries of material provisions of our articles of incorporation, the FSCMA, the Commercial Code and related laws, all as currently in effect. The following summaries are subject to, and are qualified in their entirety by reference to, our articles of incorporation and the applicable provisions of the FSCMA and the Commercial Code. We have filed copies of our articles of incorporation and these laws (except for the newly enacted the FSCMA) as exhibits to registration statements under the Securities Act or the Securities Exchange Act previously filed by us.

Dividends

We distribute dividends to our shareholders in proportion to the number of shares owned by each shareholder. The Common Shares represented by the ADSs have the same dividend rights as other outstanding Common Shares.

Holders of Non-Voting Shares are entitled to receive dividends in priority to the holders of Common Shares in an amount not less than 9% of the par value of the Non-Voting Shares as determined by the board of directors at the time of their issuance. If the amount available for

76

dividends is less than the aggregate amount of such minimum dividend, we do not have to declare dividends on the Non-Voting Shares.

We may declare dividends annually at the annual general meeting of shareholders which is held within three months after the end of the fiscal year. We pay the annual dividend shortly after the annual general meeting to the shareholders of record as of the end of the preceding fiscal year. We may distribute the annual dividend in cash or in Shares. However, a dividend of Shares must be distributed at par value. Dividends in Shares may not exceed one-half of the annual dividend. In addition, we may declare, and distribute in cash, interim dividends pursuant to a board resolution once a fiscal year. We have no obligation to pay any annual dividend unclaimed for five years from the payment date.

Under the Commercial Code, we may pay an annual dividend only to the extent the net asset amount in our balance sheets exceeds the sum of the following: (i) our stated capital, (ii) the total amount of our capital surplus reserve and legal reserve accumulated up to the end of the relevant dividend period, and (iii) the legal reserve to be set aside for annual dividend. We may not pay an annual dividend unless we have set aside as earned surplus reserve an amount equal to at least 10% of the cash portion of the annual dividend or unless we have accumulated earned surplus reserve of not less than one-half of our stated capital. We may not use legal reserve to pay cash dividends but may transfer amounts from legal reserve to capital stock or use legal reserve to reduce an accumulated deficit.

Distribution of Free Shares

In addition to paying dividends in Shares out of our retained or current earnings, we may also distribute to our shareholders an amount transferred from our capital surplus or legal reserve to our stated capital in the form of free shares. We must distribute such free shares to all our shareholders in proportion to their existing shareholdings.

Preemptive Rights and Issuance of Additional Shares

We may issue authorized but unissued shares at the times and, unless otherwise provided in the Commercial Code, on the terms our board of directors may determine. All our shareholders are generally entitled to subscribe for any newly issued Shares in proportion to their existing shareholdings. We must offer new Shares on uniform terms to all shareholders who have preemptive rights and are listed on our shareholders’ register as of the relevant record date. Under the Commercial Code, we may vary, without shareholders’ approval, the terms of these preemptive rights for different classes of shares. We must give public notice of the preemptive rights regarding new Shares and their transferability at least two weeks before the relevant record date. Our board of directors may determine how to distribute Shares for which preemptive rights have not been exercised or where fractions of Shares occur.

Under our articles of incorporation, we may issue new Shares pursuant to a board resolution to persons other than existing shareholders, who in these circumstances will not have preemptive rights, if the new Shares are:

•     offered publicly or to underwriters for underwriting pursuant to the FSCMA;

•     issued to members of our employee stock ownership association pursuant to the FSCMA;

•     represented by depositary receipts pursuant to the FSCMA;

•     issued in a general public offering pursuant to a board resolution in accordance with the FSCMA, the amount of which is no more than 10% of the outstanding Shares;

•     issued to our creditors pursuant to a debt-equity swap;

77

•     issued to domestic or foreign corporations pursuant to a joint venture agreement, strategic coalition or technology inducement agreement when deemed necessary for management purposes; or

•     issued to domestic or foreign financial institutions when necessary for raising funds in emergency cases.

In addition, we may issue convertible bonds or bonds with warrants, each up to an aggregate principal amount of Won 2,000 billion, to persons other than existing shareholders.

Members of our employee stock ownership association, whether or not they are our shareholders, generally have a preemptive right to subscribe for up to 20% of the Shares publicly offered pursuant to the FSCMA. This right is exercisable only to the extent that the total number of Shares so acquired and held by members of our employee stock ownership association does not exceed 20% of the total number of Shares then issued. As of December 31, 2010, our employees owned, through our employee stock ownership association, approximately 0.01% of our common stock in their association accounts and 2.54% of our common stock in their employee accounts.

General Meeting of Shareholders

We hold the annual general meeting of shareholders within three months after the end of each fiscal year. The record date of the register of shareholders is December 31 of each year, and such shareholders listed on the register of shareholder as of the record date are entitled to exercise their right at the general meeting of shareholders. Subject to a board resolution or court approval, we may hold an extraordinary general meeting of shareholders:

•     as necessary;

•     at the request of holders of an aggregate of 3% or more of our outstanding Shares;

•     at the request of shareholders holding an aggregate of 1.5% or more of our outstanding Shares for at least six months; or

•     at the request of our audit committee.

Holders of Non-Voting Shares may request a general meeting of shareholders only after the Non-Voting Shares become entitled to vote or “enfranchised,” as described under “— Voting Rights” below.

We must give shareholders written notice setting out the date, place and agenda of the meeting at least two weeks before the date of the general meeting of shareholders. However, for holders of 1% or less of the total number of issued and outstanding voting Shares, we may give notice by placing at least two public notices in at least two daily newspapers or by notices to be posted on the electronic disclosure database system maintained by the Financial Supervisory Service or the Korea Exchange at least two weeks in advance of the meeting. Currently, we useThe Seoul Shinmun published in Seoul,The Maeil Shinmunpublished in Taegu andThe Kwangju Ilbopublished in Kwangju for this purpose. Shareholders not on the shareholders’ register as of the record date are not entitled to receive notice of the general meeting of shareholders or attend or vote at the meeting. Holders of Non-Voting Shares, unless enfranchised, are not entitled to receive notice of general meetings of shareholders, but may attend such meetings. Our general meetings of shareholders are held either in Pohang or Seoul.

Voting Rights

Holders of our Common Shares are entitled to one vote for each Common Share, except that voting rights of Common Shares held by us, or by a corporate shareholder that is more than 10% owned by us either directly or indirectly, may not be exercised. The Commercial Code and the FSCMA permitted cumulative voting, under which voting method each shareholder would have multiple voting

78

rights corresponding to the number of directors to be appointed in the voting and may exercise all voting rights cumulatively to elect one director.

Our shareholders may adopt resolutions at a general meeting by an affirmative majority vote of the voting Shares present or represented at the meeting, where the affirmative votes also represent at least one-fourth of our total voting Shares then issued and outstanding. However, under the Commercial Code and our articles of incorporation, the following matters, among others, require approval by the holders of at least two-thirds of the voting Shares present or represented at a meeting, where the affirmative votes also represent at least one-third of our total voting Shares then issued and outstanding:

•     amending our articles of incorporation;

•     removing a director;

•     effecting any dissolution, merger or consolidation of us;

•     transferring the whole or any significant part of our business;

•     effecting our acquisition of all of the business of any other company;

•     issuing any new Shares at a price lower than their par value; or

•     approving matters required to be approved at a general meeting of shareholders, which have material effects on our assets, as determined by the Board of Directors.

In general, holders of Non-Voting Shares are not entitled to vote on any resolution or receive notice of any general meeting of shareholders. However, in the case of amendments to our articles of incorporation, or any merger or consolidation of us, or in some other cases that affect the rights or interests of the Non-Voting Shares, approval of the holders of Non-Voting Shares is required. We may obtain the approval by a resolution of holders of at least two-thirds of the Non-Voting Shares present or represented at a class meeting of the holders of Non-Voting Shares, where the affirmative votes also represent at least one-third of our total issued and outstanding Non-Voting Shares. In addition, the holders of Non-Voting Shares may be entitled to vote during the period between the general meeting of shareholders in which required preferred dividends are not paid to such holders until the next general meeting of shareholders at which the payment of such preferred dividends to such holders is declared. The holders of enfranchised Non-Voting Shares have the same rights as holders of Common Shares to request, receive notice of, attend and vote at a general meeting of shareholders.

Shareholders may exercise their voting rights by proxy. A shareholder may give proxies only to another shareholder, except that the Government may give proxies to a designated public official and a corporate shareholder may give proxies to its officers or employees.

Holders of ADRs exercise their voting rights through the ADR depositary, an agent of which is the record holder of the underlying Common Shares. Subject to the provisions of the deposit agreement, ADR holders are entitled to instruct the ADR depositary how to vote the Common Shares underlying their ADSs.

Rights of Dissenting Shareholders

In some limited circumstances, including the transfer of the whole or any significant part of our business and our merger or consolidation with another company, dissenting shareholders have the right to require us to purchase their Shares. Only the shareholders who have executed a share purchase agreement evidencing their acquisition of the relevant Shares on or prior to the day immediately following the public disclosure of the board resolutions approving any of the aforementioned transactions have the rights to require us to purchase their Shares. To exercise this right, shareholders, including holders of Non-Voting Shares, must submit to us a written notice of their intention to dissent before the general meeting of shareholders. Within 20 days after the relevant

79

resolution is passed at a meeting, the dissenting shareholders must request us in writing to purchase their Shares. We are obligated to purchase the Shares of dissenting shareholders within one month after the expiration of the20-day period. The purchase price for the Shares is required to be determined through negotiation between the dissenting shareholders and us. If we cannot agree on a price through negotiation, the purchase price will be the average of (1) the weighted average of the daily Share prices on the Korea Exchange for the two-month period before the date of the adoption of the relevant board resolution, (2) the weighted average of the daily Share price on the Korea Exchange for the one month period before the date of the adoption of the relevant resolution and (3) the weighted average of the daily Share price on the Korea Exchange for the one week period before such date of the adoption of the relevant resolution. However, the court may determine this price if we or dissenting shareholders do not accept the purchase price. Holders of ADSs will not be able to exercise dissenter’s rights unless they have withdrawn the underlying common stock and become our direct shareholders.

Register of Shareholders and Record Dates

Our transfer agent, Kookmin Bank, maintains the register of our shareholders at its office in Seoul, Korea. It registers transfers of Shares on the register of shareholders on presentation of the Share certificates.

The record date for annual dividends is December 31. For the purpose of determining the shareholders entitled to annual dividends, the register of shareholders may be closed for the period from January 1 to January 31 of each year. Further, for the purpose of determining the shareholders entitled to some other rights pertaining to the Shares, we may, on at least two weeks’ public notice, set a record dateand/or close the register of shareholders for not more than three months. The trading of Shares and the delivery of share certificates may continue while the register of shareholders is closed.

Annual Report

At least one week before the annual general meeting of shareholders, we must make our annual report and audited financial statements available for inspection at our principal office and at all of our branch offices. In addition, copies of annual reports, the audited financial statements and any resolutions adopted at the general meeting of shareholders will be available to our shareholders.

Under the FSCMA, we must file with the FSC and the Korea Exchange (1) an annual business report within 90 days after the end of our fiscal year, (2) a half-year report within 45 days after the end of the first six months of our fiscal year, and (3) quarterly reports within 45 days after the end of the third month and the ninth month of our fiscal year. Copies of these reports are or will be available for public inspection at the FSC and the Korea Exchange.

Transfer of Shares

Under the Commercial Code, the transfer of Shares is effected by delivery of share certificates. However, to assert shareholders’ rights against us, the transferee must have his name and address registered on our register of shareholders. For this purpose, a shareholder is required to file his name, address and seal with our transfer agent. A non-Korean shareholder may file a specimen signature in place of a seal, unless he is a citizen of a country with a sealing system similar to that of Korea. In addition, a non-resident shareholder must appoint an agent authorized to receive notices on his behalf in Korea and file a mailing address in Korea. The above requirements do not apply to the holders of ADSs.

Under current Korean regulations, the Korea Securities Depository, foreign exchange banks (including domestic branches of foreign banks), financial investment companies with a brokerage, dealing or collective investment license and internationally recognized custodians may act as agents and provide related services for foreign shareholders. Certain foreign exchange controls and

80

securities regulations apply to the transfer of Shares by non-residents or non-Koreans. See “Item 10. Additional Information — Item 10.D. Exchange Controls.”

Our transfer agent is Kookmin Bank, located at36-3, Yeoido-dong, Yeongdeungpo-gu, Seoul, Korea.

Acquisition of Shares by Us

We may not acquire our own Shares except in limited circumstances, such as a reduction in capital. In addition, we may acquire Shares through purchases on the Korea Exchange or through a tender offer. Notwithstanding the foregoing restrictions, we may acquire interests in our own Shares through agreements with trust companies and asset management companies. The aggregate purchase price for the Shares may not exceed the total amount available for distribution of dividends available at the end of the preceding fiscal year less the amount of dividends and mandatory reserves required to be set aside for that fiscal year, subject to certain procedural requirements.

Under the Commercial Code, except in the case of a reduction in capital, we must resell or transfer any Shares acquired by us from a third party within a reasonable time. In general, corporate entities in which we own more than 50% equity interest may not acquire our Shares. Under the FSCMA, we are subject to certain selling restrictions for the Shares acquired by us. In the case of a reduction in capital, we must immediately cancel the Shares acquired by us.

Liquidation Rights

In the event of our liquidation, after payment of all debts, liquidation expenses and taxes, our remaining assets will be distributed among shareholders in proportion to their shareholdings. Holders of Non-Voting Shares have no preference in liquidation.

Item 10.C.  Material Contracts

None.

Item 10.D.  Exchange Controls

Shares and ADSs

The Foreign Exchange Transaction Act and the Presidential Decree and regulations under that Act and Decree (collectively, “Foreign Exchange Transaction Laws”) and the Foreign Investment Promotion Law regulate investment in Korean securities by non-residents and issuance of securities outside Korea by Korean companies. Under the Foreign Exchange Transaction Laws, non-residents may invest in Korean securities subject to procedural requirements in accordance with these laws. The FSC has also adopted, pursuant to its authority under the FSCMA, regulations that restrict investment by foreigners in Korean securities.

Subject to certain limitations, the Ministry of Strategy and Finance has the authority to take the following actions under the Foreign Exchange Transaction Laws:

•     if the Government deems it necessary on account of war, armed conflict, natural disaster or grave and sudden and significant changes in domestic or foreign economic circumstances or similar events or circumstances, the Ministry of Strategy and Finance may temporarily suspend performance under any or all foreign exchange transactions, in whole or in part, to which the Foreign Exchange Transaction Laws apply (including suspension of payment and receipt of foreign exchange) or impose an obligation to deposit, safe-keep or sell any means of payment to The Bank of Korea or certain other governmental agencies or financial institutions; and

•     if the Government concludes that the international balance of payments and international financial markets are experiencing or are likely to experience significant disruption or that

81

the movement of capital between Korea and other countries is likely to adversely affect the Won, exchange rates or other macroeconomic policies, the Ministry of Strategy and Finance may take action to require any person who intends to effect a capital transaction to obtain permission or to require any person who effects a capital transaction to deposit a portion of the means of payment acquired in such transactions with The Bank of Korea or certain other governmental agencies or financial institutions.

Government Review of Issuance of ADSs

In order for us to issue shares represented by ADSs, we are required to file a prior report of the issuance with our designated foreign exchange bank or the Ministry of Strategy and Finance, depending on the issuance amount. No further Korean governmental approval is necessary for the initial offering and issuance of the ADSs.

Under current Korean laws and regulations, the depositary bank is required to obtain our prior consent for the number of shares to be deposited in any given proposed deposit which exceeds the difference between (1) the aggregate number of shares deposited by us for the issuance of ADSs (including deposits in connection with the initial and all subsequent offerings of ADSs and stock dividends or other distributions related to these ADSs) and (2) the number of shares on deposit with the depositary bank at the time of such proposed deposit. We can give no assurance that we would grant our consent, if our consent is required.

Reporting Requirements for Holders of Substantial Interests

Under the FSCMA, any person whose direct or beneficial ownership of shares with voting rights, whether in the form of shares or ADSs, certificates representing the rights to subscribe for Shares and equity-related debt securities including convertible bonds and bonds with warrants (collectively, “Equity Securities”) together with the Equity Securities beneficially owned by certain related persons or by any person acting in concert with the person accounts for 5% or more of the total outstanding Equity Securities is required to report the status and the purpose (whether or not to exert an influence on management control over the issuer) of the holdings to the FSC and the Korea Exchange within five business days after reaching the 5% ownership interest. In addition, any change in the purpose of holding such ownership interest or a change in the ownership interest subsequent to the report which equals or exceeds 1% of the total outstanding Equity Securities is required to be reported to the FSC and the Korea Exchange within five business days from the date of the change. However, the reporting deadline of such reporting requirement is extended to the tenth day of the month immediately following the month of such change in their shareholding for (1) professional investors, as defined under the FSCMA, or (2) persons who hold shares for purposes other than management control. Those who report the purpose of shareholding as management control of the issuer are prohibited from exercising their voting rights and acquiring additional shares for five days subsequent to their report under the FSCMA.

Violation of these reporting requirements may subject a person to criminal sanctions such as fines or imprisonment and may result in a loss of voting rights with respect to the ownership of Equity Securities exceeding 5%. Furthermore, the FSC may issue an order to dispose of non-reported Equity Securities.

In addition to the reporting requirements described above, any person whose direct or beneficial ownership of a company’s shares accounts for 10% or more of the total issued and outstanding shares with voting rights (a “major stockholder”) must report the status of his or her shareholding to the Securities and Futures Commission and the Korea Exchange within five business days after he or she becomes a major stockholder. In addition, any change in the ownership interest subsequent to the report must be reported to the Securities and Futures Commission and the Korea Exchange by the fifth business day of any changes in his or her shareholding. Violation of these reporting requirements may subject a person to criminal sanctions such as fines or imprisonment.

82

Under the KRX regulations, if a company listed on the KRX KOSPI Market has submitted public disclosure of material matters to a foreign financial investment supervisory authority pursuant to the laws of the foreign jurisdiction, then it must submit a copy of the public disclosure and a Korean translation thereof to the Korea Exchange. In addition, if a company listed on the KRX KOSPI Market is approved for listing on a foreign stock exchange or determined to be de-listed from the foreign stock exchange or actually lists on, or de-lists from, a foreign stock exchange, then it must submit to the Korea Exchange a copy, together with a Korean translation thereof, of all documents submitted to, or received from, the relevant foreign government, supervisory authority or stock exchange.

Restrictions Applicable to ADSs

No Korean governmental approval is necessary for the sale and purchase of ADSs in the secondary market outside Korea or for the withdrawal of shares underlying ADSs and the delivery inside Korea of shares in connection with the withdrawal, provided that a foreigner who intends to acquire the shares must obtain an investment registration card from the Financial Supervisory Service (“FSS”) as described below. The acquisition of the shares by a foreigner must be immediately reported by the foreigner or his standing proxy in Korea to the Governor of the FSS (“Governor”).

Persons who have acquired shares as a result of the withdrawal of shares underlying the ADSs may exercise their preemptive rights for new shares, participate in free distributions and receive dividends on shares without any further governmental approval.

In addition, under the FSC regulations, effective as of November 30, 2006, we are required to file a securities registration statement with the FSC and such securities registration statement has to become effective pursuant to the FSCMA in order for us to issue shares represented by ADSs, except in certain limited circumstances.

Restrictions Applicable to Shares

Under the Foreign Exchange Transaction Laws and FSC regulations (together, the “Investment Rules”), foreigners may invest, with limited exceptions and subject to procedural requirements, in all shares of Korean companies, whether listed on the KRX KOSPI Market, unless prohibited by specific laws. Foreign investors may trade shares listed on the KRX KOSPI Market only through the KRX KOSPI Market, except in limited circumstances, including, among others:

•     odd-lot trading of shares;

•     acquisition of shares (“Converted Shares”) by exercise of warrant, conversion right under convertible bonds or withdrawal right under depositary receipts issued outside of Korea by a Korean company;

•     acquisition of shares as a result of inheritance, donation, bequest or exercise of shareholders’ rights, including preemptive rights or rights to participate in free distributions and receive dividends;

•     over-the-counter transactions between foreigners of a class of shares for which the ceiling on aggregate acquisition by foreigners, as explained below, has been reached or exceeded with certain exceptions;

•     shares acquired by direct investment as defined in the Foreign Investment Promotion Law;

•     disposal of shares pursuant to the exercise of appraisal rights of dissenting shareholders;

•     disposal of shares in connection with a tender offer;

•     acquisition of shares by a foreign depositary in connection with the issuance of depositary receipts;

83

•     acquisition and disposal of shares through overseas stock exchange market if such shares are simultaneously listed on the KRX KOSPI Market or the KRX KOSDAQ Market and such overseas stock exchange; and

•     arm’s length transactions between foreigners, if all of such foreigners belong to an investment group managed by the same person.

The Investment Rules require a foreign investor who wishes to invest in shares for the first time on the Korea Exchange (including Converted Shares) to register its identity with the FSS prior to making any such investment; however, the registration requirement does not apply to foreign investors who acquire Converted Shares with the intention of selling such Converted Shares within three months from the date of acquisition of the Converted Shares or who acquire the shares in anover-the-counter transaction or dispose of shares where such acquisition or disposal is deemed to be a foreign direct investment pursuant to the Foreign Investment Promotion Law. Upon registration, the FSS will issue to the foreign investor an investment registration card which must be presented each time the foreign investor opens a brokerage account with a financial investment company with a brokerage license or dealing license in Korea. Foreigners eligible to obtain an investment registration card include foreign nationals who are individuals residing abroad for more than six months, foreign governments, foreign municipal authorities, foreign public institutions, international financial institutions or similar international organizations, corporations incorporated under foreign laws and any person in any additional category designated by decree of the Ministry of Strategy and Finance. All Korean offices of a foreign corporation as a group are treated as a separate foreigner from the offices of the corporation outside Korea. However, a foreign corporation or depositary issuing depositary receipts may obtain one or more investment registration cards in its name in certain circumstances as described in the relevant regulations.

Upon a foreign investor’s purchase of shares through the Korea Exchange, no separate report by the investor is required because the investment registration card system is designed to control and oversee foreign investment through a computer system. However, a foreign investor’s acquisition or sale of shares outside the Korea Exchange (as discussed above) must be reported by the foreign investor or his standing proxy to the Governor at the time of each such acquisition or sale;provided, however,that a foreign investor must ensure that any acquisition or sale by it of shares outside the Korea Exchange in the case of trades in connection with a tender offer, odd-lot trading of shares or trades of a class of shares for which the aggregate foreign ownership limit has been reached or exceeded, is reported to the Governor by the Korea Securities Depository, financial investment companies with a dealing or brokerage license or securities finance companies engaged to facilitate such transaction. A foreign investor must appoint one or more standing proxies from among the Korea Securities Depository, foreign exchange banks (including domestic branches of foreign banks) financial investment companies with a dealing, brokerage or collective investment license and internationally recognized custodians which will act as a standing proxy to exercise shareholders’ rights or perform any matters related to the foregoing activities if the foreign investor does not perform these activities himself. However, a foreign investor may be exempted from complying with these standing proxy rules with the approval of the Governor in cases deemed inevitable by reason of conflict between laws of Korea and those of the home country of the foreign investor.

Certificates evidencing shares of Korean companies must be kept in custody with an eligible custodian in Korea. Only foreign exchange banks (including domestic branches of foreign banks), financial investment companies with a dealing, brokerage or collective investment license, the Korea Securities Depository and internationally recognized custodians are eligible to act as a custodian of shares for a non-resident or foreign investor. A foreign investor must ensure that his custodian deposits its shares with the Korea Securities Depository. However, a foreign investor may be exempted from complying with this deposit requirement with the approval of the Governor in circumstances where compliance with that requirement is made impracticable, including cases where compliance would contravene the laws of the home country of such foreign investor.

84

Under the Investment Rules, with certain exceptions, foreign investors may acquire shares of a Korean company without being subject to any foreign investment ceiling. As one such exception, designated public corporations are subject to a 40% ceiling on the acquisition of shares by foreigners in the aggregate. Designated public corporations may set a ceiling on the acquisition of shares by a single person according to its articles of incorporation. We set this ceiling at 3% until the discontinuation of our designation as a public corporation on September 28, 2000. As a result, we currently do not have any ceiling on the acquisition of shares by a single person or by foreigners in the aggregate. Furthermore, an investment by a foreign investor of not less than 10% of the outstanding shares with voting rights of a Korean company is defined as a direct foreign investment under the Foreign Investment Promotion Law, which is, in general, subject to the report to, and acceptance by, the Ministry of Knowledge Economy. The acquisition of shares of a Korean company by a foreign investor may also be subject to certain foreign shareholding restrictions in the event that the restrictions are prescribed in each specific law which regulates the business of the Korean company.

Under the Foreign Exchange Transaction Laws, a foreign investor who intends to acquire shares must designate a foreign exchange bank at which he must open a foreign currency account and a Won account exclusively for stock investments. No approval is required for remittance into Korea and deposit of foreign currency funds in the foreign currency account. Foreign currency funds may be transferred from the foreign currency account at the time required to place a deposit for, or settle the purchase price of, a stock purchase transaction to a Won account opened in the name of a financial investment company with a dealing, brokerage or collective investment license. Funds in the foreign currency account may be remitted abroad without any governmental approval.

Dividends on Shares are paid in Won. No governmental approval is required for foreign investors to receive dividends on, or the Won proceeds of the sale of, any shares to be paid, received and retained in Korea. Dividends paid on, and the Won proceeds of the sale of, any shares held by a non-resident of Korea must be deposited either in a Won account with the investor’s financial investment company with a dealing, brokerage or collective investment license or his Won Account. Funds in the investor’s Won Account may be transferred to his foreign currency account or withdrawn for local living expenses up to certain limitations. Funds in the Won Account may also be used for future investment in shares or for payment of the subscription price of new shares obtained through the exercise of preemptive rights.

Financial investment companies with a dealing, brokerage or collective investment license are allowed to open foreign currency accounts with foreign exchange banks exclusively for accommodating foreign investors’ stock investments in Korea. Through these accounts, these financial investment companies and asset management companies may enter into foreign exchange transactions on a limited basis, such as conversion of foreign currency funds and Won funds, as counterparty to foreign investors, without the investors having to open their own accounts with foreign exchange banks.

Item 10.E.  Taxation

The following summary is based upon tax laws of the United States and Korea as in effect on the date of this annual report onForm 20-F, and is subject to any change in United States or Korean law that may come into effect after such date. Investors in the shares of common stock or ADSs are advised to consult their own tax advisers as to the United States, Korean or other tax consequences of the purchase, ownership and disposition of such securities, including the effect of any national, state or local tax laws.

Korean Taxation

The following summary of Korean tax considerations applies to you so long as you are not:

•     a resident of Korea;

85

•     a corporation with registered office or main office located in Korea or actual management of which takes place in Korea; or

•     engaged in a trade or business in Korea through a permanent establishment or a fixed base to which the relevant income is attributable or with which the relevant income is effectively connected.

Shares or ADSs

Dividends on the Shares of Common Stock or ADSs

We will deduct Korean withholding tax from dividends paid to you at a rate of 22.0% (including resident surtax). If you are a qualified resident in a country that has entered into a tax treaty with Korea, you may qualify for a reduced rate of Korean withholding tax. See the discussion under ‘‘— Tax Treaties” below for an additional explanation on treaty benefits.

In order to obtain the benefits of a reduced withholding tax rate under an applicable tax treaty, you must submit to us, prior to the dividend payment date, such evidence of tax residence as may be required by the Korean tax authorities. Evidence of tax residence will include a certificate of your tax residency issued by a competent authority of your country of tax residence, and may be submitted to us through the ADR depositary. If we distribute to you free shares representing a transfer of earning surplus or certain capital reserves into paid-in capital, that distribution may be subject to Korean tax.

Taxation of Capital Gains

As a general rule, capital gains earned by non-residents upon the transfer of the Shares or ADSs would be subject to Korean withholding tax at a rate equal to the lesser of (i) 11.0% (including resident surtax) of the gross proceeds realized or (ii) 22.0% (including resident surtax) of the net realized gain (subject to the production of satisfactory evidence of the acquisition costs and certain direct transaction costs arising out of the transfer of such Shares or ADSs), unless such non-resident is exempt from Korean income taxation under an applicable Korean tax treaty into which Korea has entered with the non-resident’s country of tax residence. See the discussion under “— Tax Treaties” below for an additional explanation of treaty benefits. Even if you do not qualify for any exemption under a tax treaty, you will not be subject to the foregoing withholding tax on capital gains if you qualify for the relevant Korean domestic tax law exemptions discussed in the following paragraphs.

With respect to shares of our common stock, you will not be subject to Korean income taxation on capital gains realized upon the transfer of such shares through the Korea Exchange if you (i) have no permanent establishment in Korea and (ii) did not own or have not owned (together with any shares owned by any person with which you have a certain special relationship and possibly including the shares represented by the ADSs) 25% or more of our total issued and outstanding shares at any time during the calendar year in which the sale occurs and during the five calendar years prior to the calendar year in which the sale occurs.

Capital gains earned by you (regardless of whether you have a permanent establishment in Korea) from the transfer of ADSs outside Korea (except for the case where you transfer the ADSs which you received as a holder of the relevant shares upon the deposit of such shares) will be exempt from Korean income taxation by virtue of the Special Tax Treatment Control Law (“STTCL”), provided that the issuance of the ADSs is deemed to be an overseas issuance under the STTCL.

If you are subject to tax on capital gains with respect to the sale of ADSs, or of shares of common stock which you acquired as a result of a withdrawal, the purchaser or, in the case of the sale of shares of common stock on the Korea Exchange or through a licensed financial investment company in Korea, the licensed financial investment company, is required to withhold Korean tax from the sales price in an amount equal to the lesser of (i) 11% (including resident surtax) of the gross realization proceeds or (ii) 22% (including resident surtax) of the net realized gain (subject to the production of satisfactory evidence of the acquisition costs and certain direct transaction costs arising

86

out of the transfer of such Shares or ADSs) and to make payment of these amounts to the Korean tax authority, unless you establish your entitlement to an exemption under an applicable tax treaty or domestic tax law. To obtain the benefit of an exemption from tax pursuant to a tax treaty, you must submit to the purchaser or the licensed financial investment company, or through the ADR depositary, as the case may be, prior to or at the time of payment, such evidence of your tax residence as the Korean tax authorities may require in support of your claim for treaty benefits. See the discussion under “— Tax Treaties” below for an additional explanation on claiming treaty benefits.

Tax Treaties

Korea has entered into a number of income tax treaties with other countries (including the United States), which would reduce or exempt Korean withholding tax on dividends on, and capital gains on transfer of, shares of our common stock or ADSs. For example, under theKorea-United States income tax treaty, reduced rates of Korean withholding tax of 16.5% or 11.0% (respectively, including resident surtax, depending on your shareholding ratio) on dividends and an exemption from Korean withholding tax on capital gains are available to residents of the United States that are beneficial owners of the relevant dividend income or capital gains, subject to certain exceptions. However, under Article 17 (Investment of Holding Companies) of theKorea-United States income tax treaty, such reduced rates and exemption do not apply if (i) you are a United States corporation, (ii) by reason of any special measures, the tax imposed on you by the United States with respect to such dividends or capital gains is substantially less than the tax generally imposed by the United States on corporate profits, and (iii) 25% or more of your capital is held of record or is otherwise determined, after consultation between competent authorities of the United States and Korea, to be owned directly or indirectly by one or more persons who are not individual residents of the United States. Also, under Article 16 (Capital Gains) of theKorea-United States income tax treaty, the exemption on capital gains does not apply if you are an individual, and (a) you maintain a fixed base in Korea for a period or periods aggregating 183 days or more during the taxable year and your ADSs or shares of common stock giving rise to capital gains are effectively connected with such fixed base or (b) you are present in Korea for a period or periods of 183 days or more during the taxable year.

You should inquire whether you are entitled to the benefit of an income tax treaty with Korea. It is the responsibility of the party claiming the benefits of an income tax treaty in respect of dividend payments or capital gains to submit to us, the purchaser or the financial investment company with a brokerage license, as applicable, a certificate as to his or her tax residence. In the absence of sufficient proof, we, the purchaser or the financial investment company with a brokerage license, as applicable, must withhold tax at the normal rates. In addition, in order for you to obtain the benefit of a tax exemption on certain Korean source income (e.g., dividends and capital gains) under an applicable tax treaty, Korean tax law requires you (or your agent) to submit the application for tax exemption along with a certificate of your tax residency issued by a competent authority of your country of tax residence, subject to certain exceptions. Such application should be submitted to the relevant district tax office by the ninth day of the month following the date of the first payment of such income.

Inheritance Tax and Gift Tax

If you die while holding an ADS or donate an ADS, it is unclear whether, for Korean inheritance and gift tax purposes, you will be treated as the owner of the shares of common stock underlying the ADSs. If the tax authority interprets depositary receipts as the underlying share certificates, you may be treated as the owner of the shares of common stock and your heir or the donee (or in certain circumstances, you as the donor) will be subject to Korean inheritance or gift tax presently at the rate of 10% to 50%; provided that the value of the ADSs or shares of common stock is greater than a specified amount.

87

If you die while holding a share of common stock or donate a share of common stock, your heir or donee (or in certain circumstances, you as the donor) will be subject to Korean inheritance or gift tax at the same rate as indicated above.

At present, Korea has not entered into any tax treaty relating to inheritance or gift taxes.

Securities Transaction Tax

If you transfer shares of common stock on the KRX KOSPI Market, you will be subject to securities transaction tax at the rate of 0.15% and an agriculture and fishery special surtax at the rate of 0.15% of the sale price of the shares of common stock. If you transfer shares of common stock on the KRX KOSDAQ Market, you will be subject to securities transaction tax at the rate of 0.3%. If your transfer of the shares of common stock is not made on the Korea Exchange, subject to certain exceptions, you will be subject to securities transaction tax at the rate of 0.5% and will not be subject to an agriculture and fishery special surtax.

Depositary receipts constitute share certificates subject to the securities transaction tax. The transfer of share certificates listed on the New York Stock Exchange, the NASDAQ National Market or other qualified foreign exchanges is exempt from the securities transaction tax under the Securities Transaction Tax Law. Accordingly, once the ADSs are listed on the New York Stock Exchange, your transfer of ADRs should not be subject to the securities transaction tax. In principle, the securities transaction tax, if applicable, must be paid by the transferor of the shares or rights. When the transfer is effected through a securities settlement company, such settlement company is generally required to withhold and pay the tax to the tax authorities. When such transfer is made through a financial investment company with a brokerage license only, such financial investment company is required to withhold and pay the tax. Where the transfer is effected by a non-resident without a permanent establishment in Korea, other than through a securities settlement company or a financial investment company with a brokerage license, the transferee is required to withhold the securities transaction tax.

United States Taxation

This summary describes the material U.S. federal income tax consequences for a U.S. holder (as defined below) of owning our shares of common stock or ADSs. This summary applies to you only if you hold shares of common stock or ADSs as capital assets for tax purposes. This summary does not apply to you if you are a member of a class of holders subject to special rules, such as:

•     a dealer in securities or currencies;

•     a trader in securities that elects to use amark-to-market method of accounting for your securities holdings;

•     a bank;

•     a life insurance company;

•     a tax-exempt organization;

•     a person that holds shares of common stock or ADSs that are a hedge or that are hedged against interest rate or currency risks;

•     a person that holds shares of common stock or ADSs as part of a straddle or conversion transaction for tax purposes;

•     a person whose functional currency for tax purposes is not the U.S. dollar; or

•     a person that owns or is deemed to own 10% or more of any class of our stock.

This summary is based on laws, treaties and regulatory interpretations in effect on the date hereof, all of which are subject to change, possibly on a retroactive basis.

88

Please consult your own tax advisers concerning the U.S. federal, state, local and other national tax consequences of purchasing, owning and disposing of shares of common stock or ADSs in your particular circumstances.

For purposes of this summary, you are a “U.S. holder” if you are a beneficial owner of a share of common stock or ADS that is:

•     a citizen or resident of the United States;

•     a U.S. domestic corporation; or

•     subject to U.S. federal income tax on a net income basis with respect to income from the share of common stock or ADS.

Shares of Common Stock and ADSs

In general, if you hold ADSs, you will be treated as the holder of the shares of common stock represented by those ADSs for U.S. federal income tax purposes, and no gain or loss will be recognized if you exchange an ADS for the shares of common stock represented by that ADS.

Dividends

The gross amount of cash dividends that you receive (prior to deduction of Korean taxes) generally will be subject to U.S. federal income taxation as foreign source dividend income. Dividends paid in Won will be included in your income in a U.S. dollar amount calculated by reference to the exchange rate in effect on the date of your (or, in the case of ADSs, the depositary’s) receipt of the dividend, regardless of whether the payment is in fact converted into Dollars. If such a dividend is converted into Dollars on the date of receipt, you generally should not be required to recognize foreign currency gain or loss in respect of the dividend income. U.S. holders should consult their own tax advisers regarding the treatment of any foreign currency gain or loss on any Won received by U.S. holders that are converted into Dollars on a date subsequent to receipt.

Subject to certain exceptions for short-term and hedged positions, the U.S. dollar amount of dividends received by an individual prior to January 1, 2013 with respect to the ADSs and common stock will be subject to taxation at a maximum rate of 15% if the dividends are “qualified dividends.” Dividends paid on the ADSs and common stock will be treated as qualified dividends if (i) we are eligible for the benefits of a comprehensive income tax treaty with the United States that the Internal Revenue Service has approved for the purposes of the qualified dividend rules and (ii) we were not, in the year prior to the year in which the dividend was paid, and are not, in the year in which the dividend is paid, a passive foreign investment company (“PFIC”). The income tax treaty between Korea and the United States (“Treaty”) has been approved for the purposes of the qualified dividend rules, and we believe we are eligible for benefits under the Treaty. Based on our audited financial statements and relevant market and shareholder data, we believe that we were not treated as a PFIC for U.S. federal income tax purposes with respect to our 2009 or 2010 taxable year. In addition, based on our audited financial statements and our current expectations regarding the value and nature of our assets, the sources and nature of our income, and relevant market and shareholder data, we do not anticipate becoming a PFIC for our 2011 taxable year. You should consult your own tax advisers regarding the availability of the reduced dividend tax rate in the light of your own particular circumstances.

Distributions of additional shares in respect of shares of common stock or ADSs that are made as part of a pro-rata distribution to all of our shareholders generally will not be subject to U.S. federal income tax.

89

Sales and Other Dispositions

For U.S. federal income tax purposes, gain or loss that you realize on the sale or other disposition of shares of common stock or ADSs will be capital gain or loss, and will be long-term capital gain or loss if the shares of common stock or ADSs were held for more than one year. Your ability to offset capital losses against ordinary income is limited. Long-term capital gain recognized by an individual U.S. holder generally is subject to taxation at a reduced rate.

Foreign Tax Credit Considerations

You should consult your own tax advisers to determine whether you are subject to any special rules that limit your ability to make effective use of foreign tax credits, including the possible adverse impact of failing to take advantage of benefits under the income tax treaty between the United States and Korea. If no such rules apply, you generally may claim a credit, up to any applicable reduced rates provided under the Treaty, against your U.S. federal income tax liability for Korean taxes withheld from dividends on shares of common stock or ADSs, so long as you have owned the shares of common stock or ADSs (and not entered into specified kinds of hedging transactions) for at least a16-day period that includes the ex-dividend date. Instead of claiming a credit, you may, at your election, deduct such Korean taxes in computing your taxable income, provided that you do not elect to claim a foreign tax credit for any foreign income taxes paid or accrued for the relevant tax year and subject to generally applicable limitations under U.S. tax law. Foreign tax credits will not be allowed for withholding taxes imposed in respect of certain hedged positions in securities and may not be allowed in respect of arrangements in which your expected economic profit is insubstantial. You may not be able to use the foreign tax credit associated with any Korean withholding tax imposed on a distribution of additional shares that is not subject to U.S. tax unless you can use the credit against United States tax due on other foreign-source income.

Any Korean securities transaction tax or agriculture and fishery special tax that you pay will not be creditable for foreign tax credit purposes.

The calculation of foreign tax credits and, in the case of a U.S. holder that elects to deduct foreign taxes, the availability of deductions involves the application of complex rules that depend on a U.S. holder’s particular circumstances. You should consult your own tax advisers regarding the creditability or deductibility of such taxes.

U.S. Information Reporting and Backup Withholding Rules

Payments in respect of the notes, shares of common stock or ADSs that are made within the United States or through certainU.S.-related financial intermediaries are subject to information reporting and may be subject to backup withholding unless the holder (1) is a corporation or other exempt recipient or (2) provides a taxpayer identification number and certifies that no loss of exemption from backup withholding has occurred. Holders that are not U.S. persons generally are not subject to information reporting or backup withholding. However, such a holder may be required to provide a certification of itsnon-U.S. status in connection with payments received within the United States or through aU.S.-related financial intermediary.

Item 10.F.  Dividends and Paying Agents

See “Item 8.A. Consolidated Statements and Other Financial Information — Dividends” above for information concerning our dividend policies and our payment of dividends. See “Item 10.B. Memorandum and Articles of Association — Dividends” for a discussion of the process by which dividends are paid on shares of our common stock. The paying agent for payment of our dividends on ADSs in the United States is the Bank of New York Mellon.

Item 10.I.  Subsidiary Information

Not applicable

Item 11.  Quantitative and Qualitative Disclosures about Market Risk

We are exposed to foreign exchange rate and interest rate risk primarily associated with underlying liabilities, and to changes in the commodity prices of principal raw materials and the market value of our equity investments. Following evaluation of these positions, we selectively enter into derivative financial instruments to manage the related risk exposures. These contracts are entered into with major financial institutions, which minimizes the risk of credit loss. The activities of our finance division are subject to policies approved by our senior management. These policies address the use of derivative financial instruments, including the approval of counterparties, setting of limits and investment of excess liquidity. Our general policy is to hold or issue derivative financial instruments for hedging purposes. From time to time, we may also enter into derivative financial contracts for trading purposes.

Exchange Rate Risk

Korea is our most important market and, therefore, a substantial portion of our cash flow is denominated in Won. Most of our exports are denominated in Dollars. Japan is also an important market for us, and we derive significant cash flow denominated in Yen. We are exposed to foreign exchange risk related to foreign currency denominated liabilities and anticipated foreign exchange payments. Anticipated foreign exchange payments, which represent a substantial sum and are mostly denominated in Dollars, relate primarily to imported raw material costs and freight costs. Foreign currency denominated liabilities relate primarily to foreign currency denominated debt. We use, to a limited extent, cross-currency interest rate swaps to reduce our exchange rate exposure with respect to foreign currency denominated debt. Under cross-currency interest rate swaps, we typically agree with the other parties to exchange, at the maturity date, a fixed amount denominated in one currency with a fixed amount denominated in another currency. Until the maturity date, we agree to exchange interest payments, at specified intervals, calculated based on different interest rates for each currency. We also use, to a limited extent, currency forward contracts to purchase Dollars to reduce our exchange rate exposure. Under currency forward contracts, we typically agree with the other parties to exchange, at the maturity date, a fixed amount denominated in Dollars with an amount denominated in Yen or Won at a fixed exchange rate.

As of December 31, 2010, we had entered into swap contracts, currency forward contracts and currency future contracts. We may incur losses under our existing contracts or any swap or other derivative product transactions entered into in the future. See Note 24 of Notes to Consolidated Financial Statements.

91

Interest Rate Risk

We are also subject to market risk exposure arising from changing interest rates. A reduction of interest rates increases the fair value of our debt portfolio, which is primarily of a fixed interest nature. From time to time, we use, to a limited extent, interest rate swaps to reduce interest rate volatility on some of our debt and manage our interest expense by achieving a balanced mixture of floating and fixed rate debt. As of December 31, 2010, we entered into two interest rate swap contracts.

The following table summarizes the carrying amounts, fair values, principal cash flows by maturity date and weighted average interest rates of our short-term and long-term liabilities as of December 31, 2010 which are sensitive to exchange ratesand/or interest rates. The information is presented in Won, which is our reporting currency.

Commodity Price Risk

We are exposed to market risk of price fluctuations related to the purchase of raw materials, especially iron ore and coal. To ensure adequate supply of raw materials, we enter into long-term supply contracts to purchase iron ore, coal, nickel, chrome, stainless steel scrap and LNG. These contracts generally have terms of three to ten years and provide for periodic price adjustments to then-market prices. The long-term contracts to purchase iron ore and coal generally provide for quarterly adjustments to the purchase prices to be determined through negotiation between the supplier and us. Such price negotiations are driven by various factors, including the global economic outlook, global market prices of raw materials and steel products, supply and demand outlook of raw materials and production costs of raw materials. Typically, globally influenced buyers and sellers of raw materials determine benchmark prices of raw materials, based on which other buyers and sellers negotiate their prices after taking into consideration the quality of raw materials and other factors. In case of iron ore, if we fail to agree on the quarterly price adjustment within a predetermined deadline, the supplier and we typically agree on the purchase price based on the index price that reflects the spot market price as well as the quality of iron ore and transportation expense. As of December 31, 2010, 323 million tons of iron ore and 52 million tons of coal remained to be purchased under long-term supply contracts. Increases in prices of our key raw materials and our inability to pass along such increases to our customers could adversely affect our margins and profits. A 5% increase in the

92

price of coal, iron ore and LNG in 2010 would have increased our operating expenses by Won 568 billion in 2010.

Equity Price Risk

We are exposed to equity price risk primarily from changes in the stock price of SK Telecom and Nippon Steel Corporation. As of December 31, 2010, we hold a 2.90% interest in SK Telecom (excluding shares placed as collateral for exchangeable bonds issued in August 2008) and a 3.50% interest in Nippon Steel Corporation. We have not entered into any derivative instruments or any other arrangements to manage our equity price risks.

•     taxes and duties upon the transfer of securities (i.e., when shares are deposited or withdrawn from deposit); and

•     fees and expenses incurred in connection with the delivery or servicing of shares on deposit.

Depositary fees payable upon the issuance and surrender of ADSs are typically paid to the depositary by the brokers (on behalf of their clients) receiving the newly issued ADSs from the depositary and by the brokers (on behalf of their clients) delivering the ADSs to the depositary for surrender. The brokers in turn charge these fees to their clients. Depositary fees payable in connection with distributions of cash or securities to ADS holders and the depositary services fee are charged by the depositary to the holders of record of ADSs as of the applicable ADS record date.

The depositary fees payable for cash distributions are generally deducted from the cash being distributed. In the case of distributions other than cash (i.e., stock dividend, rights), the depositary charges the applicable fee to the ADS record date holders concurrent with the distribution. In the case of ADSs registered in the name of the investor (whether certificated or uncertificated in direct registration), the depositary sends invoices to the applicable record date ADS holders. In the case of ADSs held in brokerage and custodian accounts (via the Korea Securities Depositary, or KSD), the depositary generally collects its fees through the systems provided by KSD (whose nominee is the registered holder of the ADSs held in KSD) from the brokers and custodians holding ADSs in their KSD accounts. The brokers and custodians who hold their clients’ ADSs in KSD accounts in turn charge their clients’ accounts the amount of the fees paid to the depositary.

In the event of refusal to pay the depositary fees, the depositary may, under the terms of the deposit agreement, refuse the requested service until payment is received or may set off the amount of the depositary fees from any distribution to be made to such holder of ADSs.

The fees and charges that holders of our ADSs may be required to pay may vary over time and may be changed by us and by the depositary. Holders of our ADSs will receive prior notice of such changes.

Fees and Payments from the Depositary to Us

In 2010, we received the following payments from the depositary

Reimbursement of NYSE listing fees:	$	79,816.58
Reimbursement of London Stock Exchange listing fees:	$	34,852.52
Reimbursement of Tokyo Stock Exchange fees:	$	33,876.67
Reimbursement of proxy process expenses (printing, postage and distribution):	$	133,485.23
Contributions toward our investor relations efforts:	$	48,602.64

In addition, as part of its service to us, the depositary waives its fees for the standard costs associated with the administration of the ADS facility, associated operating expenses, investor relations advice and access to an internet-based tool used in our investor relations activities.

Item 15.  Controls and Procedures

a.  Disclosure Controls and Procedures

Our management has evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our disclosure controls and procedures, as such term is defined inRules 13a-15(e) and15d-15(e) under the Exchange Act, as of December 31, 2010. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report. Our disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms, and that it is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

b.  Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is a process designed by, and under the supervision of, our principal executive, principal operating and principal financial officers, and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Our internal control over financial reporting 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 our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the 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 risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management has completed an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2010 based on criteria in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management concluded that our internal control over financial reporting was effective as of December 31, 2010. Our management has excluded Daewoo International and its subsidiaries from our assessment of internal control over financial reporting as of December 31, 2010 because we acquired Daewoo International and its subsidiaries in a purchase business combination in September 2010. Daewoo International and its subsidiaries comprised approximately 5.54% of our

95

consolidated sales in 2010 and approximately 13.08% of our consolidated total assets as of December 31, 2010.

KPMG Samjong Accounting Corp. (“KPMG Samjong”), an independent registered public accounting firm, which also audited our consolidated financial statements as of, and for the year ended December 31, 2010, as stated in their report which is included herein, has issued an attestation report on the effectiveness of our internal control over financial reporting.

Item 16G.  Corporate Governance

Pursuant to the rules of the New York Stock Exchange applicable to foreign private issuers like us that are listed on the New York Stock Exchange, we are required to disclose significant differences between the New York Stock Exchange’s corporate governance standards and those that we follow under Korean law and in accordance with our own internal procedures. The following is a summary of such significant differences.

97

NYSE Corporate Governance Standards	POSCO’s Corporate Governance Practice
Director Independence
Independent directors must comprise a majority of the board	Our articles of incorporation provide that our board of directors must comprise no less than a majority of Outside Directors. Our Outside Directors must meet the criteria for outside directorship set forth under the Korean Securities and Exchange Act.
	The majority of our board of directors is independent (as defined in accordance with the New York Stock Exchange’s standards), and 8 out of 13 directors are Outside Directors. Under our articles of incorporation, we may have up to five Inside Directors and eight Outside Directors.
Nomination/Corporate Governance Committee
Listed companies must have a nomination/corporate governance committee composed entirely of independent directors	We have not established a separate nomination corporate governance committee. However, we maintain a Director Candidate Recommendation Committee composed of three Outside Directors and one Inside Director.
Compensation Committee
Listed companies must have a compensation committee composed entirely of independent directors	We maintain an Evaluation and Compensation Committee composed of four Outside Directors.
Executive Session
Listed companies must hold meetings solely attended by non-management directors to more effectively check and balance management directors	Our Outside Directors hold meetings solely attended by Outside Directors in accordance with operation guidelines of our board of directors.
Audit Committee
Listed companies must have an audit committee that is composed of minimum of three directors and satisfy the requirements ofRule 10A-3 under the Exchange Act	We maintain an Audit Committee comprised of three Outside Directors who meet the applicable independence criteria set forth under Rule 10A-3 under the Exchange Act.
Shareholder Approval of Equity Compensation Plan
Listed companies must allow their shareholders to exercise their voting rights with respect to any material revision to the company’s equity compensation plan	We currently have an Employee Stock Ownership Program. We previously provided a stock options program for officers and directors, as another equity compensation plan. However, during our annual shareholders’ meeting in February 2006, our shareholders resolved to terminate the stock option program and amended our articles of incorporation to delete the provision allowing grant of stock options to officers and directors. Consequently, since February 24, 2006, we have not granted stock options to officers and directors. Matters related to the Employee Stock Ownership Program are not subject to shareholders’ approval under Korean law.
Corporate Governance Guidelines
Listed companies must adopt and disclose corporate governance guidelines	We have adopted a Corporate Governance Charter setting forth our practices with respect to relevant corporate governance matters. Our Corporate Governance Charter is in compliance with Korean law but does not meet all requirements established by the New York Stock Exchange for U.S. companies listed on the exchange. A copy of our Corporate Governance Charter is available on our website atwww.posco.com.
Code of Business Conduct and Ethics
Listed companies must adopt and disclose a code of business conduct and ethics for directors, officers and employees, and promptly disclose any waivers of the code for directors or executive officers	We have adopted a Code of Conduct for all directors, officers and employees. A copy of our Code of Conduct is available on our website atwww.posco.com.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders

POSCO:

We have audited the accompanying consolidated statements of financial position of POSCO and subsidiaries (the “Company”) as of December 31, 2010 and 2009, and the related consolidated statements of income, changes in equity and cash flows for each of the years in the three-year period ended December 31, 2010. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements 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, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of POSCO and subsidiaries as of December 31, 2010 and 2009 and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2010, in conformity with accounting principles generally accepted in the Republic of Korea.

Accounting principles generally accepted in the Republic of Korea vary in certain significant respects from U.S. generally accepted accounting principles. Information relating to the nature and effect of such differences is presented in note 32 to the consolidated financial statements.

The accompanying consolidated financial statements as of and for the year ended December 31, 2010 have been translated into United States dollars solely for the convenience of the readers. We have audited the translation and, in our opinion, the consolidated financial statements expressed in Korean Won have been translated into United States dollars on the basis set forth in note 2 to the consolidated financial statements.

As further described in note 1 to the consolidated financial statements, POSCO acquired a controlling financial interest in Daewoo International Corporation in 2010, and the results of operations of Daewoo International Corporation for the year ended December 31, 2010 are consolidated in their entirety into POSCO’s consolidated statement of income as if the acquisition has occurred on January 1, 2010, with the pre-acquisition net earnings deducted in determining POSCO’s consolidated net income for 2010. Therefore, comparability with POSCO’s consolidated financial statements for prior years is impacted accordingly.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of POSCO’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated June 17, 2011 expressed an unqualified opinion on the effectiveness of POSCO’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm
On Internal Control Over Financial Reporting

The Board of Directors and Shareholders

POSCO:

We have audited POSCO’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). POSCO’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit 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 effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting 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 the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, POSCO maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control — Integrated Framework issued by the COSO.

As described in Management’s Report on Internal Control over Financial Reporting, management has excluded Daewoo International Corporation and its subsidiaries from its assessment of internal control over financial reporting as of December 31, 2010, because it was acquired by the Company in a purchase business combination during 2010. We have also excluded Daewoo International Corporation and its subsidiaries from our audit of internal control over financial reporting. Daewoo International Corporation and its subsidiaries comprised approximately 5.54% of the Company’s 2010 consolidated sales and approximately 13.08% of the Company’s consolidated total assets at December 31, 2010.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated statements of financial position of POSCO and subsidiaries as of December 31, 2010 and 2009, and the related consolidated statements of income, changes in equity and cash flows for each of the years in the three-year period ended December 31, 2010, and our report dated June 17, 2011 expressed an unqualified opinion on those consolidated financial statements.

Significant Changes in Scope of Consolidation

(a) On September 20, 2010, POSCO acquired 68.15% of the capital shares of Daewoo International Corporation in order to enhance its competitiveness through securing the export capability and to create the synergy effect between POSCO and its subsidiaries. Based on the resolution of the Board of Directors on April 23, 2010, POSCO signed a share purchase agreement with Daewoo International Corporation’s shareholders including Korea Asset Management Corporation on August 30, 2010, and obtained an approval from the Fair Trade Commission Republic of Korea for business acquisition on September 13, 2010. The results of operations of Daewoo International Corporation for the year ended December 31, 2010 are consolidated in their entirety into in each line items of consolidated statement of income as if the acquisition has occurred on January 1, 2010 and the pre-acquisition net earnings are deducted in determining our consolidated net income. Therefore, comparability with POSCO’s consolidated financial statements for prior years is impacted accordingly.

2.   Basis of Presenting Consolidated Financial Statements and Summary of Significant Accounting Policies

The Company prepares the consolidated financial statements in accordance with generally accepted accounting principles in the Republic of Korea and applied the same accounting policies that were adopted in the previous year’s consolidated financial statements.

The significant accounting policies followed by the Company in the preparation of the accompanying consolidated financial statements are summarized below:

Basis of consolidated financial statements presentation

POSCO and its domestic subsidiaries maintain their accounting records in Korean won and prepare statutory financial statements in the Korean language in conformity with accounting principles generally accepted in the Republic of Korea. Certain accounting principles applied by the Company that conform with financial accounting standards and accounting principles in the Republic of Korea may not conform with generally accepted accounting principles in other countries. Accordingly, these consolidated financial statements are intended for use by those who are informed about Korean accounting principles and practices. The accompanying consolidated financial statements have been derived and translated into English from the Korean language consolidated financial statements. Certain information attached to the Korean language consolidated financial statement, but not required for a fair presentation of POSCO and its subsidiaries’ financial position, results of operations or cash flows, is not presented on the accompanying consolidated financial statements.

Cash and cash equivalents

The Company considers short-term deposits with maturities of three months or less on the acquisition date to be cash equivalents. Government grants received before the grants are used for specific purposes from third parties are presented as a reduction of cash and cash equivalents.

Revenue recognition

The Company’s revenue categories consist of goods sold, services rendered, construction contracts and other income. Revenue from the sale of goods is measured at the fair value of the consideration received or receivable, net of returns and allowances, trade discounts and volume rebates. Revenue is recognized when the significant risks and rewards of ownership have been transferred to the buyer, recovery of the consideration is probable, the associated costs and possible return of goods can be estimated reliably, and there is no continuing Company involvement with the goods.

Revenue from services provided is recognized based on the percentage of completion method when the amount of revenue, the costs incurred, the costs to complete and stage of completion at the end of reporting period can be reliably measured, and it is probable that future economic benefits will flow into the Company.

Revenue from construction contracts are recognized in proportion to the percentage of completion when the outcome of the contract can be reliably measured. The percentage of completion is assessed by reference to costs incurred for work performed to date to the estimated total contract costs or surveys of work performed. When the outcome of a construction contract cannot be estimated reliably, contract revenue is recognized only to the extent of contract costs incurred that are likely to be recoverable. An expected loss on a contract is recognized immediately in the consolidated statement of income.

Other income is recognized when the revenue recognition process is completed, the amount of revenue is reliably measured and it is probable that future economic benefits will flow into the Company.

Allowance for doubtful accounts

Allowance for doubtful accounts is estimated based on an analysis of individual accounts and past experience of collection and presented as a deduction from trade accounts and notes receivable.

When the terms of trade accounts and notes receivable (the principal, interest rate or term) are modified, either through a court order, such as a reorganization, or by mutual formal agreement, resulting in a reduction in the present value of the future cash flows due to the Company, the difference between the carrying value of the relevant accounts and notes receivable and the present value of the future cash flows is recognized as bad debt expense.

Inventories

The costs of inventories are determined using the moving-weighted average method whilematerials-in-transit are determined using the specific identification method. Amounts of inventory are written down to net realizable value due to losses occurring in the normal course of business and the allowance is reported as a contra inventory account, while the related charge is recognized in cost of goods sold. Gains and losses pertaining to physical inventory adjustments are also included in cost of goods sold.

Investments in securities

Upon acquisition, the Company classifies debt and equity securities (excluding investments in investees and joint ventures) into the following categories:held-to-maturity,available-for-sale or trading securities. This classification is reassessed at the end of each reporting period.

Investments in debt securities which the Company has the intent and ability to hold to maturity are classified asheld-to-maturity securities. Securities that are acquired principally for the purpose of selling in the short term are classified as trading securities. Investments not classified as eitherheld-to-maturity or trading securities are classified asavailable-for-sale securities.

A security is recognized initially at its acquisition cost, which includes the market value of the consideration given and any other transaction costs. After initial recognition,held-to-maturity securities are accounted for at amortized costs in the consolidated statements of financial position and trading andavailable-for-sale securities are accounted for at their fair values, however, non-marketable securities are accounted for at their acquisition costs if their fair values cannot be reliably estimated. The fair value of marketable securities is determined using quoted market prices as of the period end.

Trading securities are subsequently carried at fair value. Gains and losses arising from changes in the fair value of trading securities are included in the consolidated statement of income in the period in which they arise.Available-for-sale securities are subsequently carried at fair value.

Cumulative unrealized gains and losses arising from changes in the fair value ofavailable-for-sale securities are recognized as accumulated other comprehensive income (loss), net of tax, directly in equity.Held-to-maturity investments are carried at amortized cost with interest income and expense recognized in the consolidated statement of income using the effective interest method.

Management reviews investments in securities whenever events or changes in circumstances indicate that the carrying amount of the investments may not be recoverable. Impairment losses are recognized when the estimated recoverable amounts are less than the carrying amount and it is not obviously evidenced that impairment is unnecessary.

Trading securities are presented as current assets.Available-for-sale securities, which mature within one year from the end of the reporting period or where the likelihood of disposal within one year from the end of the reporting period is probable, are presented as current assets.Held-to-maturity securities, which mature within one year from the end of the reporting period, are presented as current assets.

Equity method investments

Investments in equity securities of companies, over which the Company has the ability to exercises a significant influence, are recorded using the equity method of accounting. Under the equity method, the Company records changes in its proportionate ownership in the book value of the investee in current operations, as capital adjustments, as adjustments to retained earnings or adjustments to equity in earnings or losses of equity method accounted investees, depending on the nature of the underlying change in the book value of the investee. When the Company’s share of losses in an investee equals or exceeds its interest in the investee, including preferred stock or other long term loans and receivables issued by the investees, the Company does not recognize further losses, unless it has obligations or made payments on behalf of the investees. Gains and losses on transactions between the Company and its investees are eliminated to the extent of the Company’s interest in each investee.

The excess of the acquisition cost of an investment in an investee over the Company’s share of the fair value of the identifiable net assets acquired is amortized using the straight-line method over its estimated useful life, not exceeding 20 years. When acquisition cost of investments in an investee is less than the Company’s interest on the fair value of the identifiable net assets acquired, such difference is recognized using the straight-line method as a gain over the weighted average period of useful lives of the depreciable and amortizable non-monetary assets. The remainder over the fair value of identifiable non-monetary assets is recognized as a gain in the period of acquisition. Also, the Company’s interest on the difference between fair value and carrying value of identifiable assets and liabilities of an investee, at the time of acquisition, is depreciated or reversed in accordance with accounting policies of related assets or liabilities of an investee.

Foreign currency financial statements of equity method investees are translated into Korean won using the exchange rates in effect as of the end of the reporting period for assets and liabilities (the exchange rates on the acquisition date for capital accounts), and annual average exchange rates for income and expenses. Cumulated translation gains or losses are included in accumulated other comprehensive income, a component of shareholders’ equity.

The Company’s proportionate unrealized profit arising from sales by the Company to equity method investees, sales by the equity method investees to the Company or sales between equity method investees are eliminated to the extent of the Controlling Company’s ownership.

Natural resources exploration investments

Investment in exploration and development, including the Myanmar mining site, of natural resources such as natural gas and mineral reserves are initially accounted for at cost as part of non-current investment in the statement of financial position. When the reserves are proved to have commercially producible quantities of reserves, the exploration investment account is transferred to mining rights as an intangible asset and is amortized over its expected period of commercial production.

Borrowings that are directly attributable to exploration investments are initially accounted for as part of long-term withholdings. When the reserves are proved to have commercially producible quantities of reserves, the Company transfers such borrowings to long-term debt and recognizes the cumulative interest expense and gain and loss on translation of foreign currency from the date when such borrowings were first obtained up to the date when the reserve were proved. Conversely, in case of a failure in commercial production, the Company deducts such borrowings from the amount of exploration investment and recognizes any remaining balance as a loss in the current period.

Property, plant and equipment

Property, plant and equipment are stated at cost except for certain assets subject to upward revaluations in accordance with the Asset Revaluation Law. Assets acquired by investment in kind or gift are stated at its fair value.

Depreciation is computed using the straight-line method or declining-balance method over the estimated useful lives of the assets, as follows:

	Estimated Useful Live
Buildings and structures	5-60 years
Machinery and equipment	2-25 years
Vehicles	2-10 years
Tools	2-10 years
Furniture and fixtures	2-10 years
Capital lease asset(*)	2-18 years

(*) Capital lease asset is depreciated over the shorter of the lease term or the estimated useful lives of the asset

The Company recognizes interest costs and other financial charges on borrowings associated with the production, acquisition, construction or development of property, plant and equipment as an expense in the period in which they are incurred.

Significant additions or improvements extending useful lives of assets are capitalized. Normal maintenance and repairs are charged to expense as incurred.

Management reviews property, plant and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss is recognized when the expected estimated undiscounted future net cash flows from the use of the asset and its eventual disposal are less than its carrying amount. However, if the recoverable amount of a tangible asset, for which impairment loss was recognized in prior periods, exceeds its carrying amount in subsequent periods, the amount of impairment loss recognized shall be reversed to the extent of an increased carrying amount of the asset that does not exceed the carrying amount that would have been determined, net of depreciation, if no impairment loss was recognized in prior periods.

Leases

The Company classifies and accounts for leases as either operating or capital, depending on the terms. Leases where the Company assumes substantially all of the risks and rewards of ownership are classified as capital leases. All other leases are classified as operating leases.

Intangible assets

Intangible assets are stated at cost, which includes acquisition cost, production cost and other costs required to prepare the asset for its intended use. Intangible assets are stated net of accumulated amortization computed using the straight-line method and others over the estimated useful lives as described below.

	Estimated Useful Live
Goodwill	5-20 years
Negative goodwill	5-10 years
Intellectual property rights	5-10 years
Research and development cost(*1)	3-10 years
Port facilities usage rights(*2)	1-75 years
Long-term electricity supply contract rights(*3)	9-15 years
Other intangible assets	2-25 years

(*1)	The costs incurred in relation to the development of new products and new technologies, including the development cost of internally used software and related costs, are recognized as development costs only if it is probable that future economic benefits that are attributable to the asset will flow into the entity and the cost of the asset can be measured reliably. The useful life of development costs is based on its estimated useful life, not to exceed 20 years from the date when the asset is available for use.
(*2)	As of December 31, 2010, port facilities usage rights are related to the quay and inventory yard donated by POSCO in April 1987 to the local bureaus of the Maritime Affairs and Fisheries in Gwangyang, Pohang, Pyoungtaek and Masan.
(*3)	The Company recognized the electricity supply contract initially at fair value as an identifiable intangible asset when the Company acquired POSCO Power Corp. The electricity supply contract which was related to the existing agreement of supplying electric power to Korea Electric Power Corporation met the criteria of recognizing identifiable intangible assets at acquisition date.

Management assesses the potential impairment of intangible assets when there is evidence that events or changes in circumstances have made the recovery of an asset’s carrying value to be unlikely. The carrying value of the intangible asset is reduced to the estimated realizable value, and an impairment loss is recorded as a reduction in the carrying value of the related asset and charged to current operations.

Discounts on debentures

Discounts on debentures are amortized over the term of the debenture using the effective interest rate method. Amortization of the discount is recorded as interest expense.

Accrued severance benefits

Employees and directors with at least one year of service are entitled to receive a lump-sum payment upon termination of their employment, based on their length of service and rate of pay at the time of termination. Accrued severance benefits represent the amount which would be payable assuming all eligible employees and directors were to terminate their employment as of the end of the reporting period. POSCO and its domestic subsidiaries have partially funded the accrued severance benefits through group severance insurance and the amounts funded under these insurance deposits are classified as a deduction from the accrued severance benefits liability. The Company made deposits to the National Pension Service in accordance with the National Pension Act of the Republic of Korea. Accordingly, accrued severance benefits in the accompanying consolidated statement of financial position are presented net of this deposit.

Restructuring of receivables

When the difference between the carrying value of receivables and the present value of future cash flows is material arising from variation of the terms of receivables (the principle, interest rate or term), either through a court order, such as a reorganization, or by mutual agreement, future cash flows expected to be earned are valued at their present value using an appropriate discount rate. The present value discounts are recovered using the effective interest rate method and are recognized as interest income.

Foreign currency transactions and translation

Monetary assets and liabilities denominated in foreign currencies are re-measured into Korean won at the exchange rates in effect at the end of the reporting period, and resulting translation gains and losses are recognized in the statement of income.

Derivative financial instruments

All derivative financial instruments are accounted for at their fair value according to the rights and obligations associated with the contracts. The resulting changes in fair value of derivative financial instruments are recognized either in the statement of income or shareholders’ equity, depending on whether the derivative financial instruments qualify as cash flow hedge. The effective portion of changes in the fair value of derivative financial instruments that are designated and qualify as cash flow hedges is recognized in shareholders’ equity as accumulated other comprehensive income (loss).

Fair value hedge accounting is applied to a derivative financial instrument purchased with the purpose of hedging the exposure to changes in the fair value of an asset or a liability or a firm commitment that is attributable to a particular risk. Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in the statement of income, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.

An embedded derivative financial instrument is separated from the host contract and accounted for as a derivative financial instrument when the economic characteristics and risks of the embedded derivative financial instrument are not clearly and closely related to the economic characteristics and risks of the host contract.

Provisions and contingent liabilities

A provision is a liability of uncertain timing or amount and shall be recognized when all of the following conditions are met:

1)	An entity has a present obligation (legal or constructive) as a result of a past event;
2)	It is probable that an outflow of resources embodying economic benefits will be required to settle the obligation; and
3)	A reliable estimate can be made of the amount of the obligation

However, when such outflow is dependent upon a future event, is not certain to occur, or cannot be reliably estimated, only disclosure regarding the contingent liability is made in the notes to the consolidated financial statements.

Treasury stock

In accordance with the cost method, the acquisition cost of the Company’s treasury stock is recorded as an adjustment to shareholders’ equity. Gain on disposal of treasury stock is recorded as other capital surplus and loss on disposal of treasury stock is first deducted from gain on disposal of treasury stock recorded in other capital surplus, with the remainder as a capital adjustment and then offset against retained earnings in accordance with the order of disposition of deficit.

Sale of receivables

The Company sells or discounts certain amounts of notes receivable to financial institutions and accounts for these transactions as a sale of the receivables if the rights and obligations relating to the receivables sold are substantially transferred to the buyers. The losses from the sale of the receivables are charged to operations as incurred.

Income tax and deferred income tax

Income tax on the income or loss for the year comprises current and deferred tax. Income tax is recognized in the statement of income except to the extent that it relates to items recognized directly in equity, in which case it is recognized in equity.

Current income tax is the expected tax payable on the taxable income for the year, using the enacted tax rates.

Deferred income tax is provided using the asset and liability method and is recognized for the future tax consequences attributable to the temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The amount of deferred income tax provided is based on the expected manner of realization or settlement of the carrying amount of assets and liabilities, using tax rates enacted or substantively enacted at the end of reporting period.

A deferred income tax asset is recognized only to the extent that it is probable that future taxable income will be available against which the unused tax losses and credits can be utilized. Deferred income tax assets are reduced to the extent that it is no longer probable that the related tax benefit will be realized.

Use of estimates

Generally accepted accounting principles require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at year-end and the reported amounts of revenues and expenses during the year. Significant items subject to such estimates and assumptions include useful lives, salvage values and recovery of property, plant and equipment; recoverability of goodwill and intangible assets; valuation allowances for receivables, inventories and realization of deferred income tax assets and fair values of derivatives. Actual results could differ materially from the estimates and assumptions used.

Elimination of the investments of investing company and the shareholders’ equity of the investees

In eliminating the investment of the investing company and the shareholders’ equity of the investee, the portion of the investee’s stockholders’ equity that belongs to non-controlling interest is separately presented. The elimination of the investments of the investing company and the stockholders’ equity of the investees are recorded as of the date of acquisition of controlling interest. The nearest closing date from acquisition of controlling interest is deemed to be acquisition date when acquisition date of interest of subsidiaries is different from closing date of subsidiaries.

Elimination of inter-company transactions

Inter-company transactions of the company are eliminated and related unrealized inter-company gains and losses are treated as follows:

(a)  Calculation of unrealized gains and losses

Unrealized gains or losses to be eliminated with respect to Company’s inventory, fixed assets and intangible assets are computed based upon average gross profit ratio of the concerned transaction. When the actual gross profit ratio is deemed materially different

Notes to Consolidated Financial Statements

from the average gross profit ratio, the actual gross profit ratio of the concerned transaction is used.

(b)  Elimination of unrealized gains and losses

Unrealized gains or losses arising from downstream intercompany transactions are fully eliminated and it is attributed to the Company’s investment. Unrealized gains or losses arising from upstream transactions are fully eliminated and it is attributed to the Company’s investment proportionately to the equity interest of the company and non-controlling interest.

Translation of foreign subsidiary’s financial statements

In translation of subsidiary’s financial statements denominated in foreign currencies, the statement of financial position items are translated at the exchange rates in effect at the end of the reporting period (but, historical exchange rates should be used for the equity items) and the profit and loss items are translated at the current year’s average exchange rates. Differences arising in translation should be treated as translation gain or loss from foreign operation and it is proportionately attributed to the company’s equity interest, recorded in accumulated other comprehensive income (loss), and non-controlling interest by equity interest owned. For the cash flow statement items, the beginning cash balances are translated at the exchange rates in effect at the end of the reporting period in prior year, the ending cash balances are translated at the end of the reporting period in current year and the other items are translated at the current year’s average exchange rates. Differences arising when translating the cash flow items are presented as effect of changes in exchange rate on cash and cash equivalents in the face of the consolidated statements of cash flows in translation should be treated as gain or loss on foreign currency translation.

US Dollar Convenience Translation

The December 31, 2010 consolidated financial statements are expressed in Korean Won and have been translated into U.S. dollars at the rate of W1,138.9 to US$1, at the Seoul Money Brokerage Services, Ltd., buying exchange rate in effect on December 31, 2010, solely for the convenience of the reader. These translations should not be construed as a representation that any or all of the amounts shown could be converted into U.S. dollars at this or any other rate.

The Company has decided to report its financial statements using International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board after December 31, 2010 and the Company will discontinue the use of Korean GAAP financial reporting. Consequently, the Company’s 2010 consolidated financial statements under IFRS may be materially different than the accompanying 2010 Korean GAAP consolidated financial statements.

31.   Segment and Regional Information

Our operating businesses are organized based on the nature of markets and customers. We have four reportable operating segments — the steel segment, the engineering and construction segment, the trading segment and a segment that contains operations of all other entities which fall below the reporting thresholds. The steel segment includes production of steel products and sale of such products. The engineering and construction segment includes planning, designing and construction of industrial plants, civil engineering projects and commercial and residential buildings, both in Korea and overseas. The trading segment consists of exporting and importing a wide range of steel products and raw materials that are both obtained from and supplied to POSCO, as well as between other suppliers and purchasers in Korea and overseas.

The segment results are measured based on sales and operating income in accordance with Korean GAAP without any adjustment for corporate allocations. The segment assets are measured based on total assets in accordance with Korean GAAP without any adjustment for corporate allocations.

32.   Significant Differences between Korean GAAP and U.S. GAAP

Reconciliation to U.S. Generally Accepted Accounting Principles

The consolidated financial statements of the Company are prepared in accordance with generally accepted accounting principles in the Republic of Korea (“Korean GAAP”), which differs in certain significant respects from generally accepted accounting principles in the United States of America (“U.S. GAAP”). Application of U.S. GAAP would have affected the consolidated financial position of POSCO as of December 31, 2010 and 2009 and the related consolidated net income for the three years ended December 31, 2010, 2009 and 2008 to the extent described below.

A description of the significant differences between Korean GAAP and U.S. GAAP as they relate to the Company is discussed in detail below.

(c) Fixed Asset Revaluation

Under Korean GAAP, certain fixed assets were subject to upward revaluations in accordance with the Asset Revaluation Law, with the revaluation increment credited to capital surplus. As a result of this revaluation, depreciation expenses on these assets were adjusted to reflect the increased basis. Under U.S. GAAP, such a revaluation is not permitted and depreciation expense should be based on historical cost. As a result, the gain or loss on sale of fixed assets determined in accordance with U.S. GAAP is different from the amount determined under Korean GAAP.

(d) Capitalized Costs

Under Korean GAAP, the Company capitalizes certain foreign exchange gains and losses on borrowings associated with property, plant and equipment during the construction period. Under U.S. GAAP, all foreign exchange gains and losses are included in the results of operations for the current period. No foreign exchange gains and losses have been capitalized for the years ended December 31, 2010, 2009 and 2008 under Korean GAAP. Depreciation of net capitalized foreign exchange gains and losses carried forward from prior periods amounted to nil, W(135) million and W841 million for the years ended December 31, 2010, 2009 and 2008, respectively.

In addition, effective from the period beginning after December 31, 2002, under Korean GAAP, interest costs that would have been theoretically avoided had expenditures not been made for assets which require a period of time to prepare them for their intended use are generally expensed as incurred, except when certain criteria are met for capitalization. The Company has adopted this application and expensed financing costs. Under U.S. GAAP, the Company is required to capitalize such amount. Capital projects that have had their progress halted would suspend the capitalization of interest.

Capitalized interests for the years ended December 31, 2010, 2009 and 2008 are as follows:

	2010			2009			2008
	(In millions of Korean Won)
Capitalized interest	W	251,948			184,955			96,980
Depreciation of capitalized interest etc.		(111,220	)		(98,328	)		(90,113	)
Net income impact	W	140,728			86,627			6,867

Under Korean GAAP, research and development costs and internal use software costs have been recorded as intangible assets and amortized over a period not exceeding 20 years. Under U.S. GAAP, organization costs as well as research and developments costs are generally expensed as incurred. In addition, certain costs incurred for software developed for internal use, U.S. GAAP requires that costs incurred in the preliminary project stage be expensed as incurred. External direct costs such as material and service, payroll or payroll related costs for employees who are directly associated with the project, and interest costs incurred when developing computer software for internal use, are capitalized and amortized on a straight-line method over the estimated useful life. Training costs, data conversion costs and general administrative costs are expensed as incurred.

(e) Investment Securities

The differences in accounting for investment securities between Korean GAAP and U.S. GAAP relate to (i) recognition of impairment losses, (ii) recognition of gain or loss on disposal of investments due to different classifications and (iii) classification of and accounting for certain non-marketable equity securities.

(i) Recognition of an impairment loss

Under Korean GAAP, investment securities are evaluated at each balance sheet date to determine whether there is any objective evidence of indicating an impairment loss. A significant deterioration in financial position of the issuer, such as bankruptcy, liquidation, negative net asset values and cessation of operations, would be the type of objective evidence that indicates an impairment loss. When any such objective evidence exists, unless there is a clear counter-evidence that recognition of impairment is unnecessary, management estimates the recoverable amount of the impaired security and recognizes any impairment loss in current operations. A significant or prolonged decline in the fair value of a marketable equity security below its carrying value would not be an indicator of an impairment loss unless there is also objective evidence that the financial position of the issuer has also deteriorated as described above.

The amount of impairment loss of a non-marketable equity security, measured as the difference between the estimated recoverable amount and its carrying amount, is charged to current operations by a write-down of the carrying amount of the investment. Foravailable-for-sale marketable equity securities carried at fair value, the impairment loss is charged to current operations by reversing the unrealized loss recorded in accumulated other comprehensive (loss) income. If the fair value of the impaired investment security subsequently recovers, a gain is recognized up to the amount of previously recognized impairment loss.

Under U.S. GAAP, a significant and prolonged decline in fair value of an equity investment below its cost would result in an impairment loss if the decline in value is determined to beother-than-temporary. The impairment loss is charged to current operations and a new cost basis is established. Any subsequent reversal of previously recognized impairment losses is prohibited.

The reconciliation of net income determined in accordance with Korean GAAP and U.S. GAAP for the year ended December 31, 2008 includedother-than-temporary impairment losses amounting to W442,840 million recognized under U.S. GAAP but not under Korean GAAP for certainavailable-for-sale marketable equity securities. The aggregate acquisition cost and fair value of theseavailable-for-sales marketable equity securities were W937,929 million and W225,646 million, respectively, at December 31, 2008 under Korean GAAP and U.S. GAAP, both of which are recorded at fair value. Under Korean GAAP, the unrealized losses recorded in accumulated comprehensive (loss) income related to these securities amounted to W615,498 million at December 31, 2008. There was no unrealized loss for U.S. GAAP purposes related to these securities due to the

F-97

POSCO and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2010 and 2009

other-than-temporary impairment losses of W442,840 million recorded in 2008 and the impairment losses recorded in the prior years of W172,658 million.

Included inother-than-temporary impairment losses recorded under U.S. GAAP in 2008 is an impairment loss of W364,878 million related to the Company’savailable-for-sale investment in MacArthur Coal Limited. The Company acquired a 10% equity interest in MacArthur Coal Limited on July 22, 2008 for W420,805 million. For Korean GAAP purposes, the Company recognized the excess of the acquisition cost of this investment over its fair value at the acquisition date as an impairment loss amounting to W96,785 million (note 7(b)). As of December 31, 2008, the fair value of this investment was W55,927 million, which was significantly lower than the Company’s acquisition cost. No additional impairment loss was recognized in the statement of income under Korean GAAP as management, based on its assessment, concluded no objective evidence existed that would indicate a significant deterioration in the financial position of MacArthur Coal Limited. For U.S. GAAP purposes, management determined that the decline in fair value of this investment isother-than-temporary and as a result, an impairment loss amounting to W364,878 million was recorded in earnings resulting in an additional impairment loss of W268,093 million.

The reconciliation of net income determined in accordance with Korean GAAP and U.S. GAAP for the year ended December 31, 2009 included impairment losses amounting to W207,000 million recognized under Korean GAAP but not under U.S. GAAP for LG Powercom. Under Korean GAAP, the Company recorded an impairment loss in 2009 because in 2009, LG Powercom & LG Telecom announced their decision to exchange shares in 2010. The Company considered the announcement as objective evidence of indicating an impairment loss since the Company would have loss upon the disposal of those shares and accordingly, the differences between the fair values and the acquisition costs were recognized as impairment losses while the Company had recordedother-than-temporary impairment losses prior to 2009 under U.S. GAAP.

The reconciliation of net income determined in accordance with Korean GAAP and U.S. GAAP for the year ended December 31, 2010 includedother-than-temporary impairment losses amounting to W12,970 million recognized under U.S. GAAP but not under Korean GAAP for certainavailable-for-sale equity securities. The aggregate acquisition cost and fair value of theseavailable-for-sales equity securities were W33,007 million and W8,571 million, respectively, at December 31, 2010 under U.S. GAAP. There was no unrealized loss for U.S. GAAP purposes related to these securities due to theother-than-temporary impairment losses of W15,071 million recorded in 2010 and the impairment losses recorded in the prior years of W9,365 million. Under Korean GAAP, the accumulated impairment losses and the unrealized losses recorded in accumulated comprehensive (loss) income related to these securities amounted to W4,626 million and W2,426 million, respectively, at December 31, 2010.

(ii) Recognition of gain on disposal of available for sale investments

The Company disposed certain securities that had been previously impaired under U.S. GAAP purposes. The fair value of these securities subsequently recovered resulting in the reversal of the impairment under Korean GAAP. As a result, the Company’s cost basis relating to those securities was higher under Korean GAAP than under U.S. GAAP. This difference in cost basis resulted in a gain of W103 million under U.S. GAAP upon disposal for the year ended December 31, 2010.

Net income impact	W	(12,867	)		210,762		(444,834	)

(iii) Classification of and accounting for certain non-marketable equity securities

Under Korean GAAP, a non-marketable equity security with no quoted price is classified asavailable-for-sale if a reasonable estimate of its fair value can be made without incurring excessive costs. Such investments in non-marketable equity securities are carried at fair value, with any unrealized gain or loss recorded as a component accumulated other comprehensive (loss) income. When a reasonable estimate of fair value cannot be made without incurring excessive costs, the investment is carried at cost within theavailable-for-sale securities category. Under U.S. GAAP, investments in non-marketable equity securities for which the fair value is not readily determinable are accounted for using the cost method and classified as other investment securities.

The Company recorded an adjustment to cancel net unrealized loss amounting to W52,614 million which recorded as a component accumulated other comprehensive loss or gain under Korean GAAP related with non-marketable securities including Nacional Minerios S.A. (formerly, Big Jump Energy Participacoes S.A) as of December 31, 2010.

The following table summarizes the consideration transferred to acquire Daewoo International and the amounts of identified assets acquired and liabilities assumed at the acquisition date, as well as the fair value of the non-controlling interest in Daewoo International at the acquisition date under U.S. GAAP.

Fair Value of Consideration Transferred:
Cash	W	3,371,481
Recognised amounts of identifiable assets acquired and liabilities assumed:
Current assets		3,991,610

Total identifiable net assets		3,174,870
Fair value of the non controlling interest in Daewoo International		1,188,745
Goodwill	W	1,385,356

The fair value of the non-controlling interest in Daewoo International of W1,188,745 million was determined on the basis of the closing market price of Daewoo International’s common shares on the acquisition date.

Among the liabilities assumed, the fair value of convertible bonds of W479,651 million is determined based on quoted market price in Singapore Stock Exchange on the acquisition date.

Under U.S. GAAP, acquisition-related costs are expensed as incurred. Under Korean GAAP, these costs are considered as part of the consideration transferred. In addition, the non-controlling interest in the acquiree is required to be recognized and measured at fair value under U.S. GAAP, however it is recorded at present ownership instruments’ proportionate share in the recognized amounts of the acquiree’s identifiable net assets under Korean GAAP. There are also differences between Korean GAAP and U.S. GAAP in the fair value of net identifiable assets acquired such as convertible bonds. Under Korean GAAP, the fair value for conversion rights should be separated and accounted for as capital surplus in equity, while U.S. GAAP, it is accounted for as part of the fair value of liability assumed for which fair value option is applied in accordance withASC 825-10.

As a result, the Company’s goodwill is higher under U.S. GAAP than under Korean GAAP amounting to W225,379 million and the impact for the each specific items are as follows.

U.S. GAAP Pro Forma Information (unaudited)

The following summarized pro forma consolidated income statement information assumes that the Daewoo International Corporation acquisition occurred as of January 1, 2009. The unaudited pro forma results reflect certain adjustments related to the acquisition, such as increased depreciation and amortization expense on assets acquired from Daewoo International resulting from the fair valuation of assets acquired in place on acquisition date, i.e. September 30, 2010. The pro forma results do not include any anticipated cost synergies or other effects of the planned integration of Daewoo International Corporation. These pro forma results are for comparative purposes only and may not be indicative of the results that would have occurred if the Company had completed these acquisitions as of the periods shown below or the results that will be attained in the future.

The unaudited pro forma results of operations are as follows:

	Year Ended
	December 31,		December 31,
	2010		2009
	(In millions of Korean Won)
Revenue	W	58,879,294	W	46,278,788
Net income		4,352,057		3,147,234

Under Korean GAAP, the results of operations are consolidated in their entirety into each line items of consolidated statement of income as if the acquisition has occurred on January 1, with the pre-acquisition net earnings deducted in determining consolidated net income while the results of operations after acquisition date are consolidated in consolidated statement of income under U.S. GAAP.

The amounts of revenue and net income of the acquiree since the acquisition date amounted to W3,389,025 million and W96,259 million, respectively.

(g)  Goodwill

Under Korean GAAP, goodwill is amortized over the useful life during which future economic benefits are expected to flow to the enterprise, not exceeding twenty years using straight-line method. Under U.S. GAAP, goodwill is not subject to amortization rather an impairment test is required at least annually.

Goodwill is tested annually for impairment and whenever events or circumstances indicate that the carrying value may not be recoverable. The evaluation of impairment involves comparing the current fair value of each of the Company’s reporting units to their recorded value, including goodwill. The Company uses a discounted cash flow model (DCF model) to determine the current fair value of its reporting units. Based on its assessment, management concluded that goodwill was not impaired as of December 31, 2010.

Under U.S. GAAP, total goodwill as of December 31, 2010 and 2009 amounted to W1,882,136 million and W389,174 million, respectively. Goodwill allocated to the steel segment, engineering and construction segment, trading segment and others segment as of December 31, 2010 amounted to W69,694 million, W217,193 million, W1,385,356 million and W209,893 million, respectively. Goodwill allocated to the steel segment, engineering and construction segment and others segment as of December 31, 2009 amounted to W56,711 million, W217,622 million and W114,841 million, respectively.

(h)  Hedge Accounting

According to the Implementation Guidance[2008-2] issued by KASB, effective January 1, 2008, the Company could change the designation of hedging prospectively when the contracts meet conditions of firm commitment whereas U.S. GAAP does not permit the prospective approach and therefore it’s not accounted for as derivative. The impact resulting from this GAAP difference is increase to net income of W23,203 million (net of income tax effect of W6,545 million) under U.S. GAAP for the year ended December 31, 2010.

(i)  Fair value Option

The FASB issued ASC 825 “The Fair Value Option for Financial Assets and Financial Liabilities”, which provides an option under which a company may irrevocably elect fair value as the initial and subsequent measurement attribute for certain financial assets and financial liabilities. This fair value option is available on acontract-by-contract basis with changes in fair value recognized in earnings as those changes occur.

The Fair value option exists for U.S. GAAP entities under ASC 825, Financial Instruments, wherein the option is unrestricted. Therefore, any investor’s equity method investments are eligible for the fair value option. However, Korean GAAP permits venture capital organizations, mutual funds, and unit trusts as well as similar entities, which have investments in associates to carry those investments at fair value, with changes in fair value reported in earnings in lieu of applying equity-method accounting.

Also, financial liabilities would be recognized at fair value with fair value changes recognized in the income statement under U.S. GAAP. However, under Korean GAAP, financial liabilities are not permitted to be measured at fair value.

The Company elected fair value option for the convertible bonds and equity method investments of Kyobo Life Insurance, while under Korean GAAP, such election is not allowed.

The impact resulting from this GAAP difference is increase to net income of W30,393 million for the convertible bonds and decrease to net income of W(32,422) million for equity method investments under U.S. GAAP for the year ended December 31, 2010.

(j)  Guarantees

Under Korean GAAP, the guarantor is required to disclose guarantees, including indirect guarantees of indebtedness of others. Under U.S. GAAP, the guarantor is required to recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. As of December 31, 2010, the aggregate initial amount of outstanding guarantees provided by the Company for the repayment of loans was W1,642,067 million, excluding guarantees issued either between parents and their subsidiaries or between corporations under common control (note 17). Upon initial recognition of the liability for the fair value of the obligation undertaken in issuing the guarantee, the corresponding amount is recorded in selling and administrative expenses in the statement of income as such obligation is undertaken on a stand alone basis for no consideration. Subsequent to initial recognition, the Company’s release from the risk of guarantee is recognized as the fair value of obligation changes. The changes in fair value are recognized in the statement of income. The Company has recognized guarantee expense amounting to W21,662 million and W837 million and W3,260 million for the years ended December 31, 2010, 2009 and 2008,

F-103

respectively. This adjustment is included in others, net in the reconciliation of net income and equity from Korean GAAP to U.S. GAAP.

(k)  Stock Appreciation Rights

Under Korean GAAP, the Company accounted for stock-based compensation in accordance with the intrinsic value method for awards that call for settlement in cash, shares, or a combination of both measures. Stock compensation liabilities at the end of each period are determined as the amount by which the moving weighted average of quoted market value of the shares of the enterprise’s stock covered by a grant exceeds the option price. The moving weighted average of quoted market value is calculated based on the weighted average market price of last one week, last one month and last two months of each period.

Under U.S. GAAP, Accounting Standards Codification (“ASC”) Topic 718, “Compensation — Stock Compensation” (Statement of Financial Accounting Standards (“SFAS”) No. 123(R)) is effective as of the beginning of the first interim or annual reporting period that begins after December 15, 2005. The Company adopted ASC Topic 718 (FAS 123(R)) on January 1, 2006 using the modified prospective method, under which a grant-date fair value approach is applied to all awards granted after the effective date and to awards modified, repurchased or cancelled after effective date. The cumulative effect of initially applying this statement is recognized as of the required effective date. The compensation expense for the portion of the awards that are outstanding at December 31, 2005 for which the requisite service period has not been rendered was determined based on its fair value on the adoption date, and any difference to be reflected as the cumulative effect of change in accounting principle, net of any related tax effect. Also, reflected in the cumulative effect of change in accounting principle is the net cumulative impact of estimating future forfeitures in the determination of periodic expense, rather than recording forfeitures when they occur as previously permitted. Prior to adoption of ASC Topic 718 (FAS 123(R)), the Company applied the intrinsic value approached under APB 25 and recorded stock-based compensation liabilities using the quoted market value of the shares of the Company’s stock in excess of option price.

The Company remeasured the value of its stock appreciation rights as of January 1, 2006 and applied the estimated future forfeitures, which resulted in a cumulative effect of change in accounting principle, net of tax, totaling W(2,970) million.

All the stock appreciation rights will be settled in cash upon vesting under service condition, therefore, stock appreciation right is classified as liability awards, and the fair value of stock options granted was remeasured as of the reporting date using a Black-Scholes option-pricing model with the following assumptions:

	2010
Dividend yield range		2.05%
Expected volatility range		23.69 ~ 27.55%
Risk-free interest rate range		2.81 ~ 2.85%
Expected lives (in years)		0.34 ~ 0.80

The percentage of the fair value of the awards that is accrued as compensation cost at the end of each period equals the percentage of the requisite service that has been rendered at that date. Changes in the fair value of the liability that occur after the end of the requisite service period are recorded as compensation cost of the period in which the changes occur.

U.S. GAAP reconciliation adjustments for stock appreciation rights granted to employees and executives recognized for the years ended December 31, 2010, 2009 and 2008 are included in others, net and are as follows:

	2010		2009		2008
	(In millions of Korean Won)
Net income impact	W	2,239		1,969		(13,056	)

The total stock compensation expenses, in accordance with U.S. GAAP, for the years ended December 31, 2010, 2009 and 2008 amount to W(12,675) million, W34,131 million and W(42,099) million, respectively.

(l)  Capitalized Repairs

Under Korean GAAP, major repair costs associated with the Company’s furnaces had been expensed as incurred, regardless of the nature of the expenditure until 2001. U.S. GAAP requires that repairs which extend an asset’s useful life or significantly increase its value be capitalized when incurred. Routine maintenance and repairs are expensed as incurred. Depreciation of capitalized repairs carried forward from prior periods has been recorded.

(m)  Derecognition of a financial asset

Under Korean GAAP, the Company sells or discounts certain accounts or notes receivable to financial institutions and accounts for these transactions as sale of the receivables if the rights and obligations relating to the receivables sold are substantially transferred to the buyers. In general, the recourse right of the transferee is not considered when determining whether certain accounts or notes receivable are transferred or not.

Under U.S. GAAP, transferred financial assets are derecognized when the transferor surrenders control over those assets. If the entity does not meet the derecognition criteria under U.S. GAAP, the transaction is accounted for as a secured borrowing with pledge of collateral, if applicable.

As of December 31, 2010, the outstanding balance of receivables derecognized under Korean GAAP was W1,396,777 million which has to be canceled under U.S. GAAP. The Company has canceled loss on the disposal of receivables amounting to W5,870 million for the year ended December 31, 2010. This adjustment is included in others, net in the reconciliation of net income and equity from Korean GAAP to U.S. GAAP.

(n) Deferred Income Taxes

In general, accounting for deferred income taxes is substantially the same between Korean GAAP and U.S. GAAP. The Company is also required to recognize the additional deferred tax effects resulting from differences between the reported Korean GAAP and U.S. GAAP amounts.

Under Korean GAAP, the elimination of the net tax effect of an intercompany transaction is recorded at the tax rate of the purchaser as a deferred tax asset that is subject to changes in tax rates or laws. Under U.S. GAAP, such net tax effect arising in the seller’s jurisdiction is recorded as a deferred charge, not as a deferred tax asset, and the tax effects of changes in tax rates or laws are included in income from continuing operations in the period that includes the enactment date. The impact resulting from this GAAP difference in applicable tax rate in elimination of the net tax effect of an intercompany transaction is a decrease to net income of W8,373 million, W21,680 million and an

F-105

POSCO and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2010 and 2009

increase to net income of W73,300 million under U.S. GAAP for the years ended December 31, 2010, 2009 and 2008, respectively. In addition, such net tax effect arising in the seller’s jurisdiction which is recorded as a deferred charge amounted to W308,840 million, W293,260 million and W339,089 million under U.S. GAAP as of December 31, 2010, 2009 and 2008, respectively while the corresponding amounts are recorded as deferred income taxes under Korean GAAP.

Under Korean GAAP, a deferred tax asset is recognized only to the extent that it is probable that taxable profit will be available against which the deductible temporary differences and tax loss and credit carryforwards can be utilized. Under U.S. GAAP, deferred tax assets are recognized and then reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized.

(o) Accounting for Uncertainty in Income Taxes

In July 2006, the FASB issued ASC Subtopic740-10, “Income Taxes — Overall” (FASB Interpretation No. 48 (“FIN 48”) — “Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109,”) which set outs a consistent framework to use to determine the appropriate level of liability for unrecognized tax benefits. This interpretation uses a two-step approach wherein a tax benefit is recognized if a position is more likely than not to be sustained based on the tax technical merits upon examination. A recognized tax position is then measured at the largest amount that is greater than 50% likely of being realized. The difference between the benefit recognized for a position in accordance with ASC Subtopic740-10 (FIN 48) and the tax benefit claimed on a tax return is referred to as an unrecognized tax benefit.

For the years ended December 31, 2008, 2009 and 2010, the Company did not have any unrecognized tax benefits and thus, no interest and penalties related to unrecognized tax benefits were accrued. The Company’s policy is to record interest and penalties related to unrecognized tax benefits as components of income tax expense in the consolidated statements of income.

The Company’s major tax jurisdiction is the Republic of Korea. With few exceptions, the tax year 2010 remain open to tax examination by the local tax authority for POSCO and its Korean subsidiaries.

The Company does not believe that it is reasonably possible that the amount of unrecognized tax benefits will significantly change within 12 months after December 31, 2010.

(p) Extractive Activities — Oil and Gas

Under U.S. GAAP, only exploration and development costs that relate directly to specific oil and gas reserves are capitalized; costs that do not relate directly to specific reserves are charged to expense for property, plant, and equipment in the oil and gas industry. Costs of topographical, geological, and geophysical studies, rights of access to properties to conduct those studies, and salaries and other expenses of geologists, geophysical crews, and others conducting those studies, which are referred to as geological and geophysical costs, are included in the exploration costs. In addition, geological and geophysical costs incurred in an entity’s oil- and gas-producing activities which do not result in acquisition of an asset shall be charged to expense.

Under Korean GAAP, expenditures including the geological and geophysical (G&G) costs are recognized as assets in practice.

The Company follows the successful efforts method of accounting for oil and gas exploration and development expenditures. Under this method, costs of successful exploratory projects and all

development projects are capitalized. Costs to drill exploratory projects that do not result in proved reserves are expensed.

Current deferred tax assets	W	56,208		334,385

Non-current deferred tax assets		830,981		208,014
Non-current deferred tax liabilities		2,043,333		737,958

The beginning of the year balance of valuation allowance was increased because of change in circumstances that caused a change in judgment regarding the realization of the related deferred tax assets in future years. Such amounts were W274,770 million, W154,375 million and W104,380 million as of December 31, 2010, 2009 and 2008, respectively, and is primarily attributable to the uncertainty regarding the realization of a portion of tax loss carryfowards and tax credit carryforwards.

In assessing the realization of deferred income tax assets, management considers whether it is more likely than not that some portion or all of the deferred income tax assets will not be realized. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred income tax liabilities and projected future taxable income in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred income tax assets are deductible or utilized, management believes it is more likely than not that the Company will realize the benefits of these deductible differences, net of the valuation allowance recorded at December 31, 2010 and 2009. The amount of the deferred income tax asset considered realizable, however, could be reduced in the near term if estimates of future taxable income are reduced.

As of December 31, 2010, the Company has available unused tax loss carryforwards of W767,007 million and investment tax credit carryforwards of W251,115 million. The amounts of tax loss carryforwards will expire if not used by the end of 2011, 2012, 2013, 2014 and 2015 and afterwards are W139,341 million, W73,638 million, W73,650 million, W90,716 million and W389,662 million, respectively. The amounts of investment tax credit carryforwards will expire if not

(r)   Comprehensive Income

Under U.S. GAAP, comprehensive income and its components are required to be presented under the provisions of ASC Topic 220, Comprehensive income, (SFAS No. 130), Reporting Comprehensive Income. Comprehensive income includes all changes in equity during the period except those resulting from investments by, or distributions to owners, including certain items not included in the current year’s results of operations. Comprehensive income for the years ended December 31, 2010, 2009 and 2008 is summarized as follows:

(s) Fair Value of Financial Instruments

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

(i)  Cash and cash equivalents, short-term financial instruments, trading securities, trade accounts and notes receivable, loans receivable, trade accounts and notes payable, and short-term borrowings

The carrying amount approximates fair value due to the short-term nature of those instruments.

(ii)  Investment securities

The fair value of market-traded investments such as listed company’s stocks, public bonds and other marketable securities are based on quoted market prices for those investments.

(iii)  Derivative financial instruments

All derivatives are recognized on the consolidated balance sheets at fair value based on quoted market prices, dealer or counterparty quotes, where available. If quoted market prices are not available, pricing or valuation models are applied to current market information to estimate fair value.

(iv)  Long-term loans and trade accounts and notes receivable

Long-term loans and trade accounts and notes receivable are reported net of specific and general provisions for impairment as well as present value discount factor. As a result, the fair values of long-term loans and trade accounts and notes receivable approximate their carrying values.

(v)  Long-term debts

The fair value of long-term debts is based on quoted market prices, where available. The fair value of convertible bonds was determined based on quoted market prices in Singapore Stock Exchange. For those notes where quoted market prices are not obtainable, a discounted cash flow model is used based on the current rates for issues with similar maturities.

The estimated fair values of the Company’s financial instruments stated under U.S. GAAP as of December 31, 2010 and 2009 are summarized as follows:

	2010				2009
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
	(In millions of Korean Won)
Cash and cash equivalents	W	3,598,822	W	3,598,822		2,196,731		2,196,731
Short-term financial instruments		2,954,351		2,954,351		5,820,447		5,820,447

Long-term debt, including current portion		14,273,415		14,451,354		9,016,668		9,144,532

(t) Fair Value of Assets and Liabilities

The Company’s financial assets and liabilities are valued utilizing the market approach to measure fair value. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. ASC Topic 820, “Fair Value Measurements and Disclosures” (SFAS 157, “Fair value measurements”), describes a fair value hierarchy based on three levels of inputs that may be used to measure fair value which are the following:

•     Level 1 — Quoted prices in active exchange markets involving identical assets or liabilities.

•     Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•     Level 3 — Unobservable inputs for the asset or liability, either directly or indirectly, and management assessments and inputs using a binomial lattice model as the valuation technique.

(u) Classification Differences in the Consolidated Statements of Income

Certain income and expense items in the Company’s consolidated statements of income including: (i) gains and losses on disposal of property, plant and equipment; (ii) impairment of property, plant and equipment; (iii) gains on recovery of allowance for doubtful accounts; (iv) other bad debt expenses; (v) reversal of stock compensation expense; (vi) donations; (vii) impairment of intangible assets; (viii) and provision for early retirement benefits have been classified as non-operating under Korean GAAP and excluded from the determination of operating income. Under U.S. GAAP, the above noted income and expense items would be included in the determination of operating income. After reclassification of those items, operating income under U.S. GAAP would be W5,510,252 million and W3,664,219 million and W7,092,851 million for the years ended December 31, 2010, 2009 and 2008, respectively.

(v) Consolidated Statement of Cash Flows

Under both Korean GAAP and U.S. GAAP, cash flows are classified under operating activities, investing activities and financing activities.

Under U.S. GAAP, cash flows related to purchases and sales of trading securities and payments and collections of guarantee deposits are classified as cash flows from operating activities. However, under Korean GAAP, they are classified as cash flows from investing activities. Net cash flows from purchases and sales of trading securities and payments and collections of guarantee deposits are W270,506 million, W777,847 million and W(55,125) million for the years ended December 31, 2010, 2009 and 2008, respectively.

Components of “Others” Financing Activities

“Others” financing activities disclosed within the Korean GAAP Consolidated Statements of cash flows are comprised of the following:

	2010			2009			2008
	(In millions of Korean Won)
Dividends paid by subsidiaries	W	(20,660	)		(16,915	)		(21,936	)
Issuance of new shares by subsidiaries		328,708			58,593			71,448
Additional acquisition of interest of subsidiaries(*)		(20,076	)		(117,458	)		(302,319	)
Proceeds from disposal of interest of subsidiaries		—			—			—
Government grants received		3,236			3,031			—
Total	W	291,208			(72,749	)		(252,807	)

(*)   Additional acquisition of non-controlling interests in a subsidiary is classified as investing activities under U.S. GAAP, while it is required to be classified as financing activities under Korean GAAP.

(w) Significant Risks and Uncertainties

Recent difficulties affecting global financial sectors, adverse conditions and volatility in worldwide credit and financial markets and general weakness of global economy have increased the uncertainty of global economic prospects in general and have adversely affected the global and Korean economies. Accordingly, the conditions of major Korean steel consuming industries, such as automobile and shipbuilding and construction, could have adverse effect on the Company’s results of operation as domestic sales are approximately 51% of total sales of the Company.

Also, fluctuation of foreign exchange rate on foreign currency denominated liabilities of the Company, such as debentures and long-term borrowings, could affect the financial condition and results of operation of the Company.

(x) Additional Segment Information and Enterprise-Wide Information

The segment information that is compiled for Korean GAAP purposes is also used by the Company’s chief operating decision maker. Therefore, there is no difference between Korean GAAP and the management approach under U.S. GAAP with respect to how the Company has identified its operating segments and measures segment results and assets for U.S. GAAP reporting purposes. While segment assets include all long-lived assets and investments in equity method investees, the determination of segment operating income does not include impairment charges for these assets nor does it include the equity in the earnings (losses) of equity method investees.

A substantial portion of the Company’s consolidated sales is from the production of steel products, which consists of hot rolled products, plates, wire rods, cold rolled products, silicon steel sheets, stainless steel products and others. The Company does not maintain consolidated sales information of each steel product line category.

(y) Recently adopted U.S. GAAP

In December 2007, the FASB issued ASC Topic 805, Business Combinations, (SFAS No. 141 (revised 2007), “Business Combinations” (“SFAS 141R”)). ASC Topic 805 establishes principles and requirements for how the acquirer in business combinations should recognize and measure identifiable assets acquired, the liabilities assumed and any non-controlling interest in the acquiree.

December 31, 2010 and 2009

ASC Topic 805 applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. There were no significant business combinations during 2009. The provisions of ASC Topic 805 were applied to the Company’s acquisition of Daewoo International. See Note 32(f).

(z) Subsequent Events

On March 11, 2011, the northeast coast of Japan experienced a severe earthquake followed by a tsunami, with continuing aftershocks. These geological events have caused significant damage in the region, including severe damage to nuclear power plants, and have impacted Japan’s power and other infrastructure. The total assets of the Company’s Japanese subsidiaries are not significant and management is not aware of any physical property damage there. A number of suppliers of the Company’s manufacturing equipment are located in Japan. Some of these suppliers were affected by the March 2011 earthquake and tsunami and some continue to be affected by unreliable power, shipping constraints and issues with their suppliers.

The Company’s major Japanese customer accounted for approximately 2.49% of the Company’s consolidated total sales for the year ended December 31, 2010. Management has been informed that this customer has not experienced any significant physical property damage or production disruptions to date. Management continues to monitor the situation and Company’s potential exposure.
