Part I

ITEM 1. BUSINESS
DuPont was founded in 1802 and was incorporated in Delaware in 1915. DuPont brings world-class science and engineering to the global marketplace in the form of innovative products, materials and services. The company believes that by collaborating with customers, governments, non-governmental organizations and thought leaders it can help find solutions to such global challenges as providing enough healthy food for people everywhere, decreasing dependence on fossil fuels, and protecting life and the environment. Total worldwide employment at December 31, 2011 , was approximately 70,000 people. The company has operations in more than 90 countries worldwide and about 65 percent of consolidated net sales are made to customers outside the United States of America (U.S.).
Subsidiaries and affiliates of DuPont conduct manufacturing, seed production or selling activities and some are distributors of products manufactured by the company. As a science and technology based company, DuPont competes on a variety of factors such as product quality and performance or specifications, continuity of supply, price, customer service and breadth of product line, depending on the characteristics of the particular market involved and the product or service provided. Most products are marketed primarily through DuPont's sales force, although in some regions, more emphasis is placed on sales through distributors. The company utilizes numerous suppliers as well as internal sources to supply a wide range of raw materials, energy, supplies, services and equipment. To ensure availability, the company maintains multiple sources for fuels and many raw materials, including hydrocarbon feedstocks. Large volume purchases are generally procured under competitively priced supply contracts. In 2011, DuPont acquired Danisco A/S (Danisco), a global enzyme and specialty food ingredients company. This acquisition was valued at $6.4 billion, plus net debt assumed of $0.6 billion.
Business Segments The company consists of 14 businesses which are aggregated into nine reportable segments based on similar economic characteristics, the nature of the products and production processes, end-use markets, channels of distribution and regulatory environment. The company's reportable segments are Agriculture, Electronics & Communications, Industrial Biosciences, Nutrition & Health, Performance Chemicals, Performance Coatings, Performance Materials, Safety & Protection and Pharmaceuticals. The company includes certain embryonic businesses not included in the reportable segments, such as pre-commercial programs, and nonaligned businesses in Other.
Agriculture Agriculture businesses, Pioneer Hi-Bred International, Inc. (Pioneer) and DuPont Crop Protection, leverage the company's technology, customer relationships and industry knowledge to improve the quantity, quality and safety of the global food supply and the global production agriculture industry. Land available for worldwide agricultural production is increasingly limited so production growth will need to be achieved principally through improving crop yields and productivity rather than through increases in planted area. The segment's businesses deliver a broad portfolio of products and services that are specifically targeted to achieve gains in crop yields and productivity, including Pioneer ® brand seed products and well-established brands of insecticides, fungicides and herbicides. Research and development focuses on leveraging technology to increase grower productivity and enhance the value of grains and soy through improved seed traits, superior seed germplasm and effective use of insecticides, herbicides and fungicides. Agriculture accounted for approximately 50 percent of the company's total research and development expense in 2011.
Sales of the company's products in the segment are affected by seasonal cropping and weather patterns. Sales and earnings performance in the Agriculture segment are strongest in the first half of the year reflecting the northern hemisphere planting season. The segment generally operates at a loss during the third and fourth quarters of the year. As a result of the seasonal nature of its business, Agriculture's inventory is at its highest level at the end of the calendar year and is sold down in the first and second quarters. Trade receivables in the Agriculture segment are at a low point at year-end and increase through the selling season to peak at the end of the second quarter.
Pioneer is a world leader in developing, producing and marketing corn hybrid and soybean varieties which improve the productivity and profitability of its customers. Additionally, Pioneer sells canola, sunflower, sorghum, inoculants, wheat and rice. As the world's population grows and the middle class expands, the need for crops for animal feed, food, biofuels and industrial uses continues to increase. The business competes with other seed and plant biotechnology companies. Pioneer seed sales amounted to 16 percent, 17 percent and 18 percent of the company's total consolidated net sales for the years ended December 31, 2011, 2010 and 2009, respectively.

ITEM 1. BUSINESS, continued Pioneer's research and development focuses on integrating high yielding germplasm with value added proprietary and/or licensed native and biotechnology traits with local environment and service expertise. Pioneer uniquely develops integrated products for specific regional application based on local product advancement and testing of the product concepts. Research and development in this arena requires long-term commitment of resources, extensive regulatory efforts and collaborations, partnerships and business arrangements to successfully bring products to market. Pioneer licenses biotechnology traits from third parties as a normal course of business. To protect its investment, the business employs the use of patents covering germplasm and native and biotechnology traits in accordance with country laws.
Pioneer is actively pursuing the development of innovations for corn hybrid, soybean varieties, canola, sunflower, wheat and rice based on market assessments of the most valuable opportunities. In corn hybrids, programs include innovations for drought and nitrogen efficiency, insect protection and herbicide tolerance. In soybean varieties, programs include products with high oleic content, multiple herbicide tolerance and insect protection.
Pioneer has seed production facilities located throughout the world. Seed production is performed directly by the business or contracted with independent growers and conditioners. Pioneer's ability to produce seeds primarily depends upon weather conditions and availability of reliable contract growers.
Pioneer markets and sells seed product primarily under the Pioneer ® brand but also sells and distributes products utilizing additional brand names. Pioneer promotes its products through multiple marketing channels around the world. In the corn and soybean markets of the U.S. Corn Belt, Pioneer ® brand products are sold through a specialized force of independent sales representatives. Outside of North America Pioneer's products are marketed through a network of subsidiaries, joint ventures and independent producer-distributors.
DuPont Crop Protection serves the global production agriculture industry with crop protection products for field crops such as wheat, corn, soybean and rice; specialty crops such as fruit, nut, vine and vegetables; and non-crop segments, including forestry and land management. Principal crop protection products are weed control, disease control and insect control products. Crop Protection products are marketed and sold to growers and other end users through a network of wholesale distributors and crop input retailers. The sales growth of the business' insect control portfolio is led by DuPont TM Rynaxypyr ® insecticide, a product registered for sale in over 80 countries and sold under four key brands for use across a broad range of core agricultural crops.
The major commodities, raw materials and supplies for the Agriculture segment include: corn and soybean seeds, benzene and carbamic acid related intermediates, copper, insect control products, natural gas, soybeans and sulfonamides.

Pharmaceuticals On October 1, 2001, DuPont Pharmaceuticals was sold to the Bristol-Myers Squibb Company. DuPont retained its interest in Cozaar ® (losartan potassium) and Hyzaar ® (losartan potassium with hydrochlorothiazide), which are used in the treatment of hypertension. DuPont has exclusively licensed worldwide marketing and manufacturing rights for Cozaar ® and Hyzaar ® to Merck & Co., Inc. (Merck).

Pharmaceuticals' Cozaar ® /Hyzaar ® income is the sum of two parts: income related to a share of the profits from North American sales and certain markets in Europe, and royalty income derived from worldwide contract net sales linked to the exclusivity term in a particular country. Patents and exclusivity started to expire in prior years and the U.S. exclusivity for Cozaar ® ended in April 2010. The worldwide agreement terminates when the following conditions are met: (i) the Canadian exclusivity ends (which occurred in January 2012), and (ii) North American sales fall below a certain level, which could occur by year end 2012. The company experienced its first significant step-down in income from Cozaar ® /Hyzaar ® in 2010 and expects a continued step-down to zero when the contract ends. In general, management expects a traditional earnings and cash decline for a drug going off patent in the pharmaceutical industry to continue until the contract ends.
Backlog In general, the company does not manufacture its products against a backlog of orders and does not consider backlog to be a significant indicator of the level of future sales activity. Production and inventory levels are based on the level of incoming orders as well as projections of future demand. Therefore, the company believes that backlog information is not material to understanding its overall business and should not be considered a reliable indicator of the company's ability to achieve any particular level of revenue or financial performance.

ITEM 1. BUSINESS, continued Intellectual Property DuPont believes that its intellectual property estate provides it with an important competitive advantage. It has an established global network of attorneys, as well as branding, advertising and licensing professionals, to procure, maintain, protect, enhance and gain value from this estate.
The company has a large portfolio of and is licensed under various patents. These definite-lived patents cover many products, processes and product uses. These patents protect many aspects of the company's significant research programs and the goods and services it sells. The actual protection afforded by these patents varies from country to country and depends upon the scope of coverage of each individual patent as well as the availability of legal remedies in each country. DuPont owns about 19,000 worldwide patents and is awaiting action on about 18,000 worldwide patent applications. In 2011, the company was granted 910 U.S. patents, the highest number for a single year in the company's history, and about 2,100 international patents. DuPont's rights under its patents and licenses, as well as the products made and sold under them, are important to the company as a whole, and to varying degrees, important to each reportable segment. Trade secrets are an important element of the company's intellectual property. Many of the processes used to make DuPont products are kept as trade secrets which, from time to time, may be licensed to third parties. DuPont vigilantly protects all of its intellectual property including its trade secrets. When the company discovers that its trade secrets have been unlawfully taken, it reports the matter to governmental authorities for investigation and potential criminal action, as appropriate. In addition, the company takes measures to mitigate any potential impact , which may include civil actions seeking redress, restitution and/or damages based on loss to the company and/or unjust enrichment.
Ownership of and access to intellectual property rights, pa rticularly those relating to biotechnology and germplasm, will continue to be important to Pioneer and its competitors. The environment in which Pioneer competes is characterized by the use among competitors of intellectual property rights, including patent lawsuits, to gain advantage in commercial markets. In support of its business, Pioneer continues to build a large collection of intellectual property rights related to biotechnology and germplasm and to license technology from others, including competitors. Pioneer endeavors to obtain such licenses on commercially reasonable terms.
The company has about 2,450 unique trademarks for its products and services and approximately 22,500 registrations for these trademarks worldwide. Ownership rights in trademarks do not expire if the trademarks are continued in use and properly protected. The company has many trademarks that have significant recognition at the consumer retail level and/or business to business level.
Research and Development The company conducts research at either dedicated research facilities or manufacturing plants. There are twelve major research locations in the U.S. & Canada, with the highest concentration of facilities being located in the Wilmington, Delaware area. Reflecting the company's global interests, five major research locations are located in both the Asia Pacific and Europe, Middle East and Africa (EMEA) regions. One major location is also located in Latin America.
The objectives of the company's research and development programs are to create new technologies, processes and business opportunities in relevant fields, as well as to improve existing products and processes. Each segment of the company funds research and development activities that support its business mission. The company is expanding its offerings addressing safety, environment, energy and climate challenges in the global marketplace by developing and commercializing renewable, bio-based materials; advanced biofuels; energy-efficient technologies; enhanced safety and protection products; and alternative energy products and technologies. The goals are tied directly to business growth, including increasing food production, increasing renewable sources for energy and raw materials, and providing greater safety and protection for people and the environment. All research and development activities are administered by senior research and development management to ensure consistency with the business and corporate strategy. The future of the company is not dependent upon the outcome of any single research program.
Additional information with respect to research and development, including the amount incurred during each of the last three fiscal years, is included in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, on page 19 of this report.

ITEM 1A. RISK FACTORS
The company's operations could be affected by various risks, many of which are beyond its control. Based on current information, the company believes that the following identifies the most significant risk factors that could affect its businesses. Past financial performance may not be a reliable indicator of future performance and historical trends should not be used to anticipate results or trends in future periods.
Price increases for energy and raw materials could have a significant impact on the company's ability to sustain and grow earnings. The company's manufacturing processes consume significant amounts of energy and raw materials, the costs of which are subject to worldwide supply and demand as well as other factors beyond the control of the company. Significant variations in the cost of energy, which primarily reflect market prices for oil and natural gas and raw materials affect the company's operating results from period to period. Legislation to address climate change by reducing greenhouse gas emissions and establishing a price on carbon could create increases in energy costs and price volatility. When possible, the company purchases raw materials through negotiated long-term contracts to minimize the impact of price fluctuations. Additionally, the company enters into over-the-counter and exchange traded derivative commodity instruments to hedge its exposure to price fluctuations on certain raw material purchases. The company takes actions to offset the effects of higher energy and raw material costs through selling price increases, productivity improvements and cost reduction programs. Success in offsetting higher raw material costs with price increases is largely influenced by competitive and economic conditions and could vary significantly depending on the market served. If the company is not able to fully offset the effects of higher energy and raw material costs, it could have a significant impact on the company's financial results.
Failure to develop and market new products and manage product life cycles could impact the company's competitive position and have an adverse effect on the company's financial results. Operating results are largely dependent on the company's assessment and management of its portfolio of current, new and developing products and services and its ability to bring those products and services to market. The company plans to grow earnings by focusing on developing markets and solutions to meet increasing demand for food productivity, decrease dependency on fossil fuels and protect people, assets and the environment. This ability could be adversely affected by difficulties or delays in product development such as the inability to identify viable new products, successfully complete research and development, obtain relevant regulatory approvals, obtain intellectual property protection, or gain market acceptance of new products and services. Because of the lengthy development process, technological challenges and intense competition, there can be no assurance that any of the

8Table of Contents
Part I

ITEM 1A. RISK FACTORS, continued products the company is currently developing, or could begin to develop in the future, will achieve substantial commercial success. Sales of the company's new products could replace sales of some of its current products, offsetting the benefit of even a successful product introduction.
The company's results of operations could be adversely affected by litigation and other commitments and contingencies. The company faces risks arising from various unasserted and asserted litigation matters, including, but not limited to, product liability, patent infringement, antitrust claims, and claims for third party property damage or personal injury stemming from alleged environmental torts. The company has noted a nationwide trend in purported class actions against chemical manufacturers generally seeking relief such as medical monitoring, property damages, off-site remediation and punitive damages arising from alleged environmental torts without claiming present personal injuries. The company also has noted a trend in public and private nuisance suits being filed on behalf of states, counties, cities and utilities alleging harm to the general public. Various factors or developments can lead to changes in current estimates of liabilities such as a final adverse judgment, significant settlement or changes in applicable law. A future adverse ruling or unfavorable development could result in future charges that could have a material adverse effect on the company. An adverse outcome in any one or more of these matters could be material to the company's financial results.
In the ordinary course of business, the company may make certain commitments, including representations, warranties and indemnities relating to current and past operations, including those related to divested businesses and issue guarantees of third party obligations. If the company were required to make payments as a result, they could exceed the amounts accrued, thereby adversely affecting the company's results of operations.
The company's business, including its results of operations and reputation, could be adversely affected by process safety and product stewardship issues. Failure to appropriately manage safety, human health, product liability and environmental risks associated with the company's products, product life cycles and production processes could adversely impact employees, communities, stakeholders, the company's reputation and its results of operations. Public perception of the risks associated with the company's products and production processes could impact product acceptance and influence the regulatory environment in which the company operates. While the company has procedures and controls to manage process safety risks, issues could be created by events outside of its control including natural disasters, severe weather events and acts of sabotage.
As a result of the company's current and past operations, including operations related to divested businesses, the company could incur significant environmental liabilities. The company is subject to various laws and regulations around the world governing the environment, including the discharge of pollutants and the management and disposal of hazardous substances. As a result of its operations, including its past operations and operations of divested businesses, the company could incur substantial costs, including remediation and restoration costs. The costs of complying with complex environmental laws and regulations, as well as internal voluntary programs, are significant and will continue to be so for the foreseeable future. The ultimate costs under environmental laws and the timing of these costs are difficult to predict. The company's accruals for such costs and liabilities may not be adequate because the estimates on which the accruals are based depend on a number of factors including the nature of the matter, the complexity of the site, site geology, the nature and extent of contamination, the type of remedy, the outcome of discussions with regulatory agencies and other Potentially Responsible Parties (PRPs) at multi-party sites and the number and financial viability of other PRPs.
Market acceptance, government policies, rules or regulations and competition could affect the company's ability to generate sales from genetically modified products. The company is using biotechnology to create and improve products, particularly in its Agriculture segment. The use of biotechnology to characterize the genetic and performance characteristics of Pioneer seeds provides Pioneer with competitive advantages in the development of new products, and in the most effective placement of those products on customer acres. In addition, the company uses biotechnology to enhance the performance of its seed products through the addition of specific transgenes. The company's ability to generate sales from such products could be affected by market acceptance of genetically modified products as well as governmental policies, laws and regulations that affect the development, manufacture and distribution of products, including the testing and planting of seeds containing biotechnology traits and the import of commodity grain grown from those seeds.
The company competes with major global companies that have strong intellectual property estates supporting the use of biotechnology to enhance products, particularly in the agricultural products and production markets. Speed in discovering and protecting new technologies and bringing products based on them to market is a significant competitive advantage. Failure to predict and respond effectively to this competition could cause the company's existing or candidate products to become less

Part I

ITEM 1A. RISK FACTORS, continued competitive, adversely affecting sales.
Changes in government policies and laws could adversely affect the company's financial results. Sales outside the U.S. constitute approximately 65 percent of the company's 2011 revenue. The company anticipates that international sales will continue to represent a substantial portion of its total sales and that continued growth and profitability will require further international expansion, particularly in developing markets. Sales from developing markets represent 34 percent of the company's revenue in 2011 and the company's growth plans include focusing on expanding its presence in developing markets. The company's financial results could be affected by changes in trade, monetary and fiscal policies, laws and regulations, or other activities of U.S. and non-U.S. governments, agencies and similar organizations. These conditions include, but are not limited to, changes in a country's or region's economic or political conditions, trade regulations affecting production, pricing and marketing of products, local labor conditions and regulations, reduced protection of intellectual property rights in some countries, changes in the regulatory or legal environment, restrictions on currency exchange activities, burdensome taxes and tariffs and other trade barriers. International risks and uncertainties, including changing social and economic conditions as well as terrorism, political hostilities and war, could lead to reduced sales and profitability.
Economic factors, including inflation, deflation and fluctuations in currency exchange rates, interest rates and commodity prices could affect the company's financial results. The company is exposed to fluctuations in currency exchange rates, interest rates and commodity prices. Because the company has significant international operations, there are a large number of currency transactions that result from international sales, purchases, investments and borrowings. The companyactively manages currency exposures that are associated with net monetary asset positions, committed currency purchases and sales, foreign currencydenominated revenues and other assets and liabilities created in the normal course of business. Failure to successfully manage these risks could have an adverse impact on the company's financial position, results of operations and cash flows.
Conditions in the global economy and global capital markets may adversely affect the company's results of operations, financial condition, and cash flows. The company's business and operating results may in the future be adversely affected by global economic conditions, including instability in credit markets, declining consumer and business confidence, fluctuating commodity prices, volatile exchange rates, and other challenges that could affect the global economy. The company's customers may experience deterioration of their businesses, cash flow shortages, and difficulty obtaining financing. As a result, existing or potential customers may delay or cancel plans to purchase products and may not be able to fulfill their obligations in a timely fashion. Further, suppliers could experience similar conditions, which could impact their ability to fulfill their obligations to the company. Adversity within capital markets may impact future return on pension assets, thus resulting in greater future pension costs that impact the company's results. Future weakness in the global economy could adversely affect the company's results of operations, financial condition and cash flows in future periods.
The company's results of operations and financial condition could be seriously impacted by business disruptions and security threats. Business disruptions, including supply disruptions, increasing costs for energy, temporary plant and/or power outages and information technology system and network disruptions, could seriously harm the company's operations as well as the operations of its customers and suppliers. Like many other multinational organizations, the company faces security threats to its facilities, data and information technology infrastructure. Although it is impossible to predict the occurrences or consequences of business disruptions or security threats, they could result in reduced demand for the company's products, make it difficult or impossible for the company to deliver products to its customers or to receive raw materials from suppliers, and create delays and inefficiencies in the supply chain. The company actively manages the risks within its control that could lead to business disruptions or security breaches in order to mitigate any potential impact from business disruptions regardless of cause including acts of sabotage, terrorism or war, weather events and natural disasters. Despite these efforts, the impact from business disruptions and security breaches could significantly increase the cost of doing business or otherwise adversely impact the company's financial performance.
Inability to protect and enforce the company's intellectual property rights could adversely affect the company's financial results. Intellectual property rights, including patents, plant variety protection, trade secrets, confidential information, trademarks, tradenames and other forms of trade dress, are important to the company's business. The company endeavors to protect its intellectual property rights in jurisdictions in which its products are produced or used and in jurisdictions into which its products are imported. However, the company may be unable to obtain protection for its intellectual property in key jurisdictions. The company has designed and implemented internal controls to restrict access to and distribution of its intellectual property. Despite these

The company believes it has sufficient capacity to meet demand in 2012. Properties are primarily owned by the company; however, certain properties are leased. No title examination of the properties has been made for the purpose of this report and certain properties are shared with other tenants under long-term leases.
DuPont recognizes that the security and safety of its operations are critical to its employees, community and, indeed, to the future of the company. As such, the company has merged chemical site security into its safety core value where it serves as an integral part of its long standing safety culture. Physical security measures have been combined with process safety measures (including the use of inherently safer technology), administrative procedures and emergency response preparedness into an integrated security plan. The company has conducted vulnerability assessments at operating facilities in the U.S. and high priority sites worldwide and identified and implemented appropriate measures to protect these facilities from physical and cyber attacks. DuPont is partnering with carriers, including railroad, shipping and trucking companies, to secure chemicals in transit.

the company operates;

• Conditions in the global economy and global capital markets, including economic factors, such as inflation, deflation and fluctuations

in currency exchange rates, interest rates and commodity prices, as well as regulatory requirements;

• Impact of business disruptions, including supply disruptions, and security threats, regardless of cause, including acts of sabotage,

terrorism or war, weather events and natural disasters;

• Inability to protect and enforce the company's intellectual property rights; and

• Successful integration of acquired businesses and completion of divestitures of underperforming or non-strategic assets or businesses.
For some of the important factors that could cause the company's actual results to differ materially from those projected in any such forward-looking statements, see the Risk Factors discussion set forth under Part I, Item 1A beginning on page 8.

Overview Vision DuPont's vision is to be the world's most dynamic science company, creating sustainable solutions essential to a better, safer and healthier life for people everywhere. The company is committed to growing shareholder and societal value while reducing its environmental footprint in the value chains in which it operates, over the long-term.
Strategy The company's strategy for growth is to apply its science and technology to address three challenges driven by global population growth: feeding the world , reducing our dependence on fossil fuels and keeping people and the environment safe . Critical areas for the company's growth are innovation, differential management and productivity. Applying science to deliver innovative solutions and new products in the marketplace generates shareholder value and profitable growth. Differential management is a disciplined process to prioritize and allocate resources across businesses and geographies aligned with growth opportunities. The company continues to achieve fixed cost, working capital and variable cost productivity through disciplined business processes called DuPont Integrated Business Management (DIBM) and DuPont Production System (DPS). DIBM focuses on the business supply chain to maximize efficiency and optimize working capital, while DPS focuses on productivity outcomes to eliminate operational inefficiencies and improve lead time, cycle time and quality.

Goals The company's long-term plan includes compound annual growth targets of 7 percent for sales and 12 percent for earnings per share. In 2011, sales were up 20 percent with strong contributions across most segments with earnings per share increasing 12 percent. Sales in developing markets, which include China, India, and the countries located in Latin America, Eastern and Central Europe, Middle East, Africa, and Southeast Asia, are targeted to make up 40 percent of the company's sales by 2015, a 6 percentage point increase from 2011. In 2011, sales of new products introduced in the last four years were in line with the company's long-term target of 30 percent of total sales. Additionally, the company exceeded its 2011 goals for fixed cost and working capital productivity. The company remains on-track to exceed its three-year 2010-2012 plan of $1 billion fixed cost productivity actions and has already exceeded its three-year 2010-2012 plan of $1 billion working capital productivity. The company is committed to maintain a strong balance sheet and to return excess cash to shareholders unless there is a compelling opportunity to invest for growth.

Analysis of Operations Acquisition of Danisco In 2011, the company acquired Danisco in a transaction valued at $6.4 billion, plus net debt assumed of $0.6 billion. As part of this acquisition, DuPont incurred $85 million in transaction related costs during 2011, which were recorded in costs of goods sold and other operating charges. In 2011, the businesses acquired from Danisco contributed net sales of $1.7 billion and net income attributable to DuPont of $(7) million, which excludes $30 million after-tax ($39 million pre-tax) of additional interest expense related to the debt issued to finance the acquisition. Danisco's contributions included a $125 million after-tax ($175 million pre-tax) charge related to the fair value step-up of inventories acquired and sold during 2011.
In 2011, the company initiated a series of actions to achieve the expected cost and revenue synergies associated with the Danisco acquisition. As part of these actions, the company incurred restructuring charges totaling $53 million. Additionally, the company expects to incur about $50 million of other costs to achieve synergies through 2013, including operating enhancements, consulting fees and relocation related costs, which will be expensed as incurred. These actions are expected to produce pre-tax annual cost savings of at least $130 million beginning in 2012, a full year ahead of the original schedule.

Sales increased 20 percent, principally reflecting higher local selling prices and the sales added from businesses acquired from Danisco. Local selling prices were significantly higher for titanium dioxide, seeds, fluoroproducts and electronic products, with the latter reflecting pass through pricing for higher precious metals costs. Worldwide sales volume increased 1 percent as strong volume growth in Agriculture was largely offset by declines in Electronic & Communications, Performance Chemicals and Performance Materials. The declines occurred primarily during the fourth quarter, resulting from destocking in photovoltaics, polymer and industrial supply chains, as well as weaker demand for company products supplying consumer electronics and construction. Volume growth in Latin America was driven by Agriculture, Safety & Protection and Performance Coatings. Sales in developing markets of $13.0 billion improved 27 percent from 2010, and the percentage of total company sales in these markets increased to 34 percent from 32 percent in 2010.

2011 versus 2010 The $470 million decrease was largely attributable to a $201 million reduction of Cozaar ® /Hyzaar ® income, an increase of $150 million in net pre-tax exchange losses, the absence of a benefit of $59 million recorded in 2010 related to accrued interest associated with settlements of income tax contingencies related to prior years, the absence of $41 million in insurance recoveries and a $37 million decrease in net gains on sales of assets.

2010 versus 2009 Other income, net, was essentially flat compared to 2009, despite a decrease of $549 million of Cozaar ® /Hyzaar ® income due to the expiration of certain patents. Offsetting the reduction of Cozaar ® /Hyzaar ® income was a decrease in net pre-tax exchange losses of $192 million combined with higher income from equity affiliates of $93 million, an increase in net gains on sales of assets of $64 million, a benefit of $59 million in 2010 related to accrued interest associated with settlements of income tax contingencies related to prior years, an increase in insurance recoveries of $41 million and a $31 million combined benefit from an acquisition and an early termination of a supply agreement.

2011 versus 2010 Cost of goods sold and other operating charges (COGS) increased 20 percent. COGS as a percentage of net sales was 73 percent, unchanged from prior year, as selling price increases of $3.6 billion were offset by $2.0 billion of inflation in raw material, energy and freight costs, and $0.7 billion of higher plant operating costs, including capacity expansions . 2011 COGS also included $175 million of additional costs related to the fair value stepup of inventory acquired from Danisco, $85 million of Danisco transaction related fees and $175 million for charges related to Imprelis ® herbicide claims.

2010 versus 2009 COGS increased 17 percent, while COGS as a percent of net sales decreased 2 percentage points from 2009. The improvement principally reflects increased manufacturing utilization and higher selling prices that more than offset increases in raw material costs. Higher selling prices increased sales $1.3 billion, while raw material, energy and freight costs, adjusted for volume and currency, were up 6 percent, or $0.7 billion.

2011 versus 2010 The 2011 increase of $501 million was due to the additional selling expense of acquired companies and increased global commissions and selling and marketing investments, primarily in the Agriculture segment.

2010 versus 2009 The 2010 increase of $229 million was due to higher selling expenses, primarily in the Agriculture segment as a result of increased global commissions and selling and marketing investments related to the company's seed products, and higher non-cash pension expenses.

2011 versus 2010 The $305 million increase was primarily attributable to research and development expense from acquired companies and continued growth investment in the Agriculture segment. Both periods include a $50 million charge for payments related to a Pioneer licensing agreement prior to the business receiving regulatory approval in the third quarter 2011.

2010 versus 2009 The $273 million increase was due to continued growth investment aligned with the company's global trends, including resources to support agriculture productivity, alternative fuels and energy efficient materials, and safety and protection. In addition, research and development expense increased due to higher non-cash pension expenses and a $50 million charge for an upfront payment related to a Pioneer licensing agreement.

(Dollars in millions) 2011 2010 2009 INTEREST EXPENSE $ 447 $ 590 $ 408
The $143 million decrease in 2011 was due primarily to the absence of a $179 million pre-tax charge on the early extinguishment of debt and lower interest rates, partially offset by higher average debt resulting from financing for the Danisco acquisition. The $182 million increase in 2010 was primarily due to a $179 million pre-tax charge on the early extinguishment of debt in the fourth quarter 2010.

2011 versus 2010 The $84 million change in 2011 was due to a net $50 million restructuring charge in 2011, primarily related to restructuring charges associated with the Danisco acquisition and the absence of a $34 million net reduction in the estimated costs for prior years restructuring programs.

2010 versus 2009 The $244 million change in 2010 was due to the absence of a net $210 million restructuring charge in 2009 and a $34 million net reduction in the estimated costs for prior years restructuring programs in 2010. The $34 million net reduction resulted from lower than estimated individual severance costs and work force reductions through non-severance programs.

In 2011, the company recorded a tax provision of $772 million, reflecting an increase from 2010 largely due to pre-tax earnings growth, which was partially offset by the impact associated with the company's policy of hedging the foreign currency-denominated monetary assets and liabilities of its operations. The $244 million increase in 2010 from 2009 was largely due to an increase in pre-tax earnings and the impact associated with the company's policy of hedging the foreign currency-denominated monetary assets and liabilities of its operations. These were partially offset by net tax benefits of $49 million related to the adjustment of income tax accruals associated with settlements of tax contingencies related to prior years and $39 million for reversal of tax valuation allowance related to the net deferred tax assets of a foreign subsidiary. The decrease in the 2010 effective tax rate compared to 2009 was primarily due to favorable geographic mix of pre-tax earnings in low tax rate jurisdictions and the net tax benefits noted above.
See Note 5 to the Consolidated Financial Statements for additional details related to the provision for income taxes, as well as items that significantly impact the company's effective income tax rate.

(Dollars in millions) 2011 2010 2009 NET INCOME ATTRIBUTABLE TO DUPONT $ 3,474 $ 3,031 $ 1,755

2011 versus 2010 Net income attributable to DuPont (earnings) for 2011 increased $443 million, or 15 percent versus 2010. The increase in earnings principally reflects higher local selling prices, higher sales volume and currency benefits, partly offset by higher raw material, energy and freight costs, increased spending for growth initiatives, and lower Pharmaceuticals income. See additional information above related to changes in earnings.

2010 versus 2009 Earnings for 2010 increased $1.3 billion, or 73 percent versus 2009. The increase principally reflects higher sales volume and selling prices and the absence of a prior year restructuring charge, partly offset by higher non-cash pension costs and lower Pharmaceuticals income. See additional information above related to changes in earnings.
Corporate Outlook DuPont's full-year 2012 sales and earnings are expected to benefit from a strong agriculture economy, market-driven innovation and ongoing productivity, partially offset by headwinds created by a stronger dollar and a higher tax rate. The company expects higher operating costs including an increase in raw material, energy and freight costs, and plans to partly offset the impact of these increases with productivity programs for fixed costs reduction totaling $300 million.
The company plans to continue a differential level of capital expenditures and funding for research and development for businesses expected to have aboveaverage growth rates and margins. For 2012, targets have been set for capital expenditures totaling about

Segment Reviews Segment sales include transfers to another business segment. Products are transferred between segments on a basis intended to reflect, as nearly as practicable, the market value of the products. Segment pre-tax operating income (loss) (PTOI) is defined as operating income before income taxes, exchange gains (losses), corporate expenses and interest. All references to selling prices are on a U.S. dollar (USD) basis, including the impact of currency. A reconciliation of segment sales to consolidated net sales and segment PTOI to income before income taxes for 2011, 2010 and 2009 is included in Note 21 to the Consolidated Financial Statements.

2011 versus 2010 Pioneer seed sales reflect growth primarily in corn and soybean seeds. Volume increases in all regions were underpinned by increased acres and market position. Pricing gains in all regions reflect the introduction and penetration of new products including Optimum ® AcreMax ® 1 into the North America corn lineup. Crop Protection sales growth reflects both volume and price gains with increases in insect control, weed control and fungicides product sales, particularly continued strong demand for Rynaxypyr ® insecticide and continued expansion of picoxystrobin fungicides. Sales grew in all regions, particularly Latin America and Europe. 2011 PTOI and PTOI margin increased on continued new product penetration and leverage on volume growth, partially offset by a $175 million charge related to Imprelis ® claims. Additionally, aligned with the segment's long-term plan, research and development expense increased 15 percent to support continued growth in breeding, biotechnology and crop chemistry. 2011 and 2010 PTOI each included a licensing agreement charge of $50 million.

2010 versus 2009 Higher sales volume was primarily due to higher Pioneer seed sales in North America with market share gains for corn and soybeans. Higher global sales of Crop Protection products were led by broad-based recovery across most regions and strong demand for Rynaxypyr ® in Asia Pacific and Latin America. The higher selling prices reflect higher value product mix and pricing actions to offset the increase in raw material costs, along with a favorable currency impact. 2010 PTOI increased primarily due to the higher sales volume, partially offset by higher spending for growth investments and a $50 million charge for an upfront payment associated with a Pioneer licensing agreement. PTOI margin was flat compared to 2009.

Outlook Pioneer anticipates continued global growth in corn and soybean markets, as well as pricing gains reflecting innovative technology and the business' differentiated route to market. Specific innovations include continued penetration of the Optimum ® AcreMax TM 1 products in corn coupled with new corn hybrids, many of which include AquaMax ® technology and new soybean varieties with leading disease packages developed for local needs. Pioneer anticipates earnings growth in 2012 reflecting strong sales performance, partially offset by higher input costs resulting from commodity price increases and the weather related impact

2011 versus 2010 Sales growth reflects higher selling prices, primarily pass-through of metals prices. Lower sales volume primarily reflects destocking in photovoltaics and softness in consumer electronics in the second half 2011, which more than offset strong demand in all market segments in the first half 2011.
2011 PTOI decreased primarily due to lower volume in the second half 2011. PTOI margin decreased primarily reflecting higher metal prices, as well as weaker product mix.

2010 versus 2009 Higher sales volume was driven by strong growth in all regions, particularly in Asia Pacific and Europe, and strong demand across most market segments, particularly in photovoltaics. Higher selling prices were primarily due to pass-through of higher metals prices.
2010 PTOI and PTOI margin increases reflect substantially higher volume, particularly in photovoltaics, as well as improved productivity and the absence of a net $37 million restructuring charge in 2009.

Outlook For 2012, sales are expected to increase with photovoltaics and consumer electronics demand recovering in the second half 2012. Volume growth is expected through new and innovative products, as well as capacity investments in Tedlar ® completed in 2011 to meet global demand. Earnings are expected to increase reflecting the impact of higher volume, new product introductions and productivity initiatives.

Sales and PTOI primarily reflects the acquisition of Danisco's enzyme business. PTOI included a $70 million charge for the fair value step-up of inventories that were acquired as part of the acquisition and a $9 million restructuring charge. PTOI also included $12 million of amortization expense associated with the fair value step-up of the acquired intangible assets.

Outlook 2012 sales and earnings will reflect a full year of results from the enzyme business acquired from Danisco in 2011. Science-based innovation growth, cost synergies derived from integration, productivity gains and the absence of charges for transaction and integration related costs in 2011 are expected to contribute to earnings. Volume growth is supported by expansion

2011 versus 2010 Sales were up primarily due to the Danisco acquisition. For Solae, higher selling prices and volume reflect strong demand for specialty soy products. 2011 PTOI and PTOI margin decreased as higher sales were more than offset by a $112 million charge for transaction related costs and the fair value step-up of inventories that were acquired and a $14 million restructuring charge. PTOI also included $49 million of amortization expense associated with the fair value step-up of the acquired intangible assets.

2010 versus 2009 Higher sales volume was led by strong demand for Solae ® soy products, particularly in Latin America. 2010 PTOI and PTOI margin were essentially flat compared to 2009 as unfavorable currency impact coupled with increased manufacturing costs offset volume growth.

Outlook 2012 sales and earnings will reflect a full year of results from the specialty food ingredients business acquired from Danisco in 2011. Science-based innovation growth, cost synergies derived from integration, productivity gains and the absence of charges for transaction and integration related costs in 2011 are expected to contribute to earnings and margin expansion. Volume growth reflecting specialty soy product expansion is anticipated to support earnings and PTOI margin improvement.

2011 versus 2010 Sales increased across all regions and market segments. The increase in sales reflects favorable pricing for titanium dioxide and fluoropolymers, as well as pass-through pricing of higher raw material costs for fluorochemicals and industrial chemicals.
2011 PTOI and PTOI margin improved driven by the higher selling prices and fixed cost productivity.

2010 versus 2009 Broad-based market recovery led to sales increases in all markets and all regions, most significant in Asia Pacific, reflecting strong demand for titanium dioxide, fluoropolymers and refrigerants, with continuing adoption of ISCEON ® as a preferred retrofit to R22 refrigerant. Higher selling prices reflect favorable pricing for titanium dioxide, fluorochemicals and fluoropolymers and pass-through of higher raw material costs for industrial chemicals. 2010 PTOI and PTOI margin increases were driven by higher volume, higher selling prices, improved productivity and the absence of a net $54 million restructuring charge in 2009.

Outlook Sales are expected to increase in 2012 as a result of the continued demand for titanium dioxide, fluoropolymers and industrial chemicals and higher selling prices. Segment earnings are also expected to increase consistent with the higher sales volume, higher selling prices and continued productivity actions.

2011 versus 2010 The segment experienced continued recovery with auto builds across the globe increasing 3 percent in 2011, primarily driven by an improvement of 9 percent in North America. Higher selling prices reflect pricing actions across all regions and market segments to offset higher raw material costs, along with a favorable currency impact. Volume growth primarily reflects increased demand for OEM motor vehicle coatings and industrial coatings, particularly in the North American heavy duty truck market.
2011 PTOI increase primarily reflects the impact of higher selling prices along with a favorable currency impact. PTOI margin compression resulted from raw material costs increasing at a higher rate than selling prices which offset fixed cost productivity actions.

2010 versus 2009 The segment experienced strong recovery across most markets and regions from the global economic recession in the automotive industry in 2009, most significant in North America and Europe. Higher sales volume reflects recovery in global automotive OEM markets and strong demand in industrial coatings, particularly in the North American and European heavy duty truck markets. Higher selling prices primarily reflect pricing actions taken to offset the increase in raw material costs.
2010 PTOI and PTOI margin increases primarily reflect the impact of higher volume, particularly in industrial coatings and the OEM market, improved productivity and higher selling prices, which were partially offset by higher raw material costs.

Outlook For 2012, the segment expects sales to increase with continued recovery in the global automotive and heavy duty truck markets. The industry production forecast for automotive builds in 2012 is a 4 percent global increase, reflecting continued recovery in North America and continued growth in Asia Pacific. PTOI is expected to improve due to continued productivity efforts and pricing actions in all regions and market segments.

2011 versus 2010 Higher selling prices reflects pricing actions which offset higher feedstock costs. Lower sales volume reflects broad-based channel destocking with softening in consumer and industrial markets in the second half 2011, and production-related supply issues in ethylene-based polymers.
2011 PTOI was essentially fl at. 2011 PTOI included a $49 million benefit from the gain on the sale of a business. 2010 PTOI included a combined $58 million gain on an asset purchase due to the acquisition and early termination of a supply agree ment, a gain on the sale of a business and an insurance recovery. Lower PTOI margin primarily reflects feedstock costs increasing at a higher rate than selling prices.

2010 versus 2009 Higher sales volume was led by broad-based demand across all markets, particularly in automotive and electronics markets, with strong volume recovery in all regions, led by Asia Pacific. Higher selling prices were a combination of stronger product sales mix and higher selling prices in response to higher feedstock costs.
2010 PTOI and PTOI margin increases were primarily driven by higher sales volume, particularly in automotive, electronic and packaging markets, as well as higher selling prices and improved productivity.

Outlook 2012 sales are expected to grow due to anticipated increases in global motor vehicle OEM builds. The segment is expected to benefit in the second half 2012 from broader recovery in industrial markets, while demand in the packaging market is expected to continue to be stable. PTOI is also expected to improve due to the impact of higher sales, improved fixed cost productivity and science-based innovations for products and processes.

25Table of Contents
Part II ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS, continued

2011 PTOI increased as the impact of the MECS acquisition and a favorable currency impact more than offset higher spending for growth initiatives and higher raw material costs. The Kevlar ® expansion at Cooper River, South Carolina was completed and began commercial supply at the end of 2011.

2010 versus 2009 The increase in sales volume reflects strong recovery and increased demand across all regions, led by EMEA and Asia Pacific, and all markets, particularly in aramid and nonwoven products. Further penetration in the U.S. commercial construction markets led to higher sales as recovery in global construction markets remained weak. Sales for consulting and training services improved modestly across most regions, led by Asia Pacific and EMEA. 2010 PTOI and PTOI margin increases were primarily due to higher volume, particularly aramid and nonwoven products, and the absence of a net $45 million restructuring charge in 2009, partially offset by higher spending for growth initiatives and higher raw material costs.

Outlook For 2012, sales are expected to benefit from improved global market conditions which are anticipated to recover in the second half 2012 with demand for Kevlar ® , Nomex ® and Tyvek ® products expected to increase across all regions and market segments. Sales related to the Sustainable Solutions business are expected to increase due to clean technologies businesses and consulting growth in the areas of process safety management and sustainable operations. Sales related to the Building Innovations business are expected to increase due to further penetration in commercial construction applications. Earnings are expected to improve due to higher sales reflecting innovative growth through products such as Kevlar ® AP, as well as continued productivity actions.

The company believes its ability to generate cash from operations and access to capital markets will be adequate to meet anticipated cash requirements to fund working capital, capital spending, dividend payments, debt maturities and other cash needs. The company's liquidity needs can be met through a variety of sources, including: cash provided by operating activities, cash and cash equivalents, marketable securities, commercial paper, syndicated credit lines, bilateral credit lines, equity and long-term debt markets and asset sales. The company's current strong financial position, liquidity and credit ratings provide excellent access to the capital markets. In addition, spending and capital productivity actions have been implemented. The company will continue to monitor the financial markets in order to respond to changing conditions. Depending on these conditions, the proceeds of commercial paper may be invested in cash equivalents or marketable securities.
Pursuant to its cash discipline policy, the company seeks first to maintain a strong balance sheet and second, to return excess cash to shareholders unless the opportunity to invest for growth is compelling. Cash, cash equivalents and marketable securities provide primary liquidity to support all short-term obligations. A substantial majority of the company's cash, cash equivalents and marketable securities is held by foreign subsidiaries and is considered to be indefinitely reinvested and expected to be utilized to fund local operating activities and capital expenditure requirements. The company believes that it has sufficient sources of domestic liquidity to further support its assumption that undistributed earnings at December 31, 2011 can be considered reinvested indefinitely. The company has access to approximately $4.4 billion in unused credit lines with several major financial institutions,

26Table of Contents
Part II ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS, continued

as additional support to meet short-term liquidity needs and general corporate purposes, including letters of credit.
The company continually reviews its debt portfolio and occasionally may rebalance it to ensure adequate liquidity and an optimum debt maturity schedule. In 2011, the company issued $2.0 billion in Senior Notes and $1.0 billion in commercial paper to finance the acquisition of Danisco. Additionally, the company assumed $0.7 billion in debt as part of the acquisition, which was refinanced through the issuance of commercial paper.
The company's credit ratings impact its access to the debt capital market and cost of capital. The company remains committed to a strong financial position and strong investment-grade rating. The company's long-term and short-term credit ratings are as follows:

(Dollars in millions) 2011 2010 2009 Cash provided by operating activities $ 5,152 $ 4,559 $ 4,741
Cash provided by operating activities increased $593 million in 2011 compared to 2010. The increase was driven by higher earnings, lower contributions to pension plans and the weaker dollar, which was hedged with forward exchange contracts reflected in investing activities. These increases were partially offset by changes in operating assets and liabilities, mainly due to higher inventory. Cash provided by operating activities decreased $182 million in 2010 compared to 2009. Higher earnings were offset by changes in operating assets and liabilities, mainly due to higher sales and inventory; the stronger dollar, which was hedged with forward exchange contracts reflected in investing activities; and a contribution to the principal U.S. pension plan.

The $3.8 billion increase in 2011 was mainly due to the payment for the Danisco acquisition, higher expenditures for the purchases of property, plant and equipment, and a net increase in payments for forward exchange contract settlements; partially offset by changes in investments in short-term financial instruments. The $1.9 billion decrease in 2010 was mainly due to changes in investments in short-term financial instruments and a net increase in proceeds from forward exchange contract settlements, partially offset by an increase in payments for businesses and higher expenditures for the purchases of property, plant and equipment. Purchases of property, plant and equipment totaled $1.8 billion, $1.5 billion and $1.3 billion in 2011, 2010 and 2009, respectively. Higher spending in 2011 and 2010 reflects the company's continued investment in capacity expansion to support areas of growth. The company expects 2012 purchases of plant, property and equipment to be about $2.1 billion, an increase of $0.3 billion over 2011, driven by continued growth investments aligned with the company's global trends.

(Dollars in millions) 2011 2010 2009 Cash provided by (used for) financing activities $ 403 $ (1,829 ) $ (97 )
The $2.2 billion change in 2011 was primarily due to an increase in borrowings in 2011 to finance the Danisco acquisition as compared to a decrease in borrowings in 2010. The $1.7 billion increase in cash used for financing activities in 2010 was primarily due to a decrease in borrowings in 2010 as compared to an increase in borrowings in 2009. This was partially offset by an increase in the proceeds from the exercise of stock options net of cash used to repurchase common stock.

Dividends paid to common and preferred shareholders were $1.5 billion in 2011, 2010 and 2009. Dividends per share of common stock were $1.64 in 2011, 2010 and 2009. The common dividend declared in the first quarter 2012 was the company's 430 th consecutive dividend since the company's first dividend in the fourth quarter 1904. The company's Board of Directors authorized a $2 billion share buyback plan in June 2001. During 2011, the company purchased and retired 13.8 million shares at a total cost of $672 million under this plan. During 2010, the company purchased and retired 5.4 million shares at a total cost of $250 million under this plan. During 2009, there were no purchases of stock under this plan. As of December 31, 2011, the company has purchased 39.7 million shares at a total cost of $1.9 billion. In April 2011, the company's Board of Directors authorized a $2 billion share buyback plan. This plan will not commence until the plan authorized in June 2001 is completed. There is no expiration date on the current authorizations.

(Dollars in millions) 2011 2010 2009 Cash provided by operating activities $ 5,152 $ 4,559 $ 4,741 Purchases of property, plant and equipment (1,843 ) (1,508 ) (1,308 ) Free cash flow $ 3,309 $ 3,051 $ 3,433
Free cash flow is a measurement not recognized in accordance with generally accepted accounting principles in the U.S. (GAAP) and should not be viewed as an alternative to GAAP measures of performance. All companies do not calculate non-GAAP financial measures in the same manner and, accordingly, the company's free cash flow definition may not be consistent with the methodologies used by other companies. The company defines free cash flow as cash provided by operating activities less purchases of property, plant and equipment, and therefore indicates operating cash flow available for payment of dividends, other investing activities and other financing activities. Free cash flow is useful to investors and management to evaluate the company's cash flow and financial performance, and is an integral financial measure used in the company's financial planning process.

Critical Accounting Estimates The company's significant accounting policies are more fully described in Note 1 to the Consolidated Financial Statements. Management believes that the application of these policies on a consistent basis enables the company to provide the users of the financial statements with useful and reliable information about the company's operating results and financial condition.
The preparation of the Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts, including, but not limited to, receivable and inventory valuations, impairment of tangible and intangible assets, long-term employee benefit obligations, income taxes, restructuring liabilities, environmental matters and litigation. Management's estimates are based on historical experience, facts and circumstances available at the time and various other assumptions that are believed to be reasonable. The company reviews these matters and reflects changes in estimates as appropriate. Management believes that the following represents some of the more critical judgment areas in the application of the company's accounting policies which could have a material effect on the company's financial position, liquidity or results of operations.
Long-term Employee Benefits Accounting for employee benefit plans involves numerous assumptions and estimates. Discount rate and expected return on plan assets are two critical assumptions in measuring the cost and benefit obligation of the company's pension and other long-term employee benefit plans. Management reviews these two key assumptions annually as of December 31 st . These and other assumptions are updated periodically to reflect the actual experience and expectations on a plan specific basis as appropriate. As permitted by GAAP, actual results that differ from the assumptions are accumulated on a plan by plan basis and to the extent that such differences exceed 10 percent of the greater of the plan obligations or the applicable plan assets, the excess is amortized over the average remaining service period of active employees.
About 80 percent of the company's benefit obligation for pensions and essentially all of the company's other long-term employee benefit obligations are attributable to the benefit plans in the U.S. The company utilizes published long-term high quality corporate bond indices to determine the discount rate at measurement date. Where commonly available, the company considers indices of various durations to reflect the timing of future benefit payments.
Within the U.S., the company establishes strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes with the aim of achieving a prudent balance between return and risk. Strategic asset allocations in other countries are selected in accordance with the laws and practices of those countries. Where appropriate, asset-liability studies are also taken into

28Table of Contents
Part II ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS, continued

considerat ion. The long-term expected return on plan assets in the U.S. is based upon historical real returns (net of inflation) for the asset classes covered by the investment policy, expected performance, and projections of inflation over the long-term period during which benefits are payable to plan participants. Consistent with prior years, the long-term expected return on plan assets in the U.S. reflects the asset allocation of the plan and the effect of the company's active management of the plans' assets.
In determining annual expense for the principal U.S. pension plan, the company uses a market-related value of assets rather than its fair value. The marketrelated value of assets is calculated by averaging market returns over 36 months. Accordingly, there may be a lag in recognition of changes in market valuation. As a result, changes in the fair value of assets are not immediately reflected in the company's calculation of net periodic pension cost. The following table shows the market-related value and fair value of plan assets for the principal U.S. pension plan:

(Dollars in billions) 2011 2010 2009 Market-related value of assets $ 13.9 $ 13.9 $ 14.0 Fair value of plan assets 13.9 14.8 13.9

For plans other than the principal U.S. pension plan, pension expense is typically determined using the fair value of assets.
The following table highlights the potential impact on the company's pre-tax earnings due to changes in certain key assumptions with respect to the company's pension and other long-term employee benefit plans, based on assets and liabilities at December 31, 2011 :
Pre-tax Earnings Benefit (Charge) (Dollars in millions) 1/2 Percentage Point Increase 1/2 Percentage Point Decrease Discount rate $ 97 $ (101 ) Expected rate of return on plan assets 88 (88 )
Additional information with respect to pension and other long-term employee benefits expenses, liabilities and assumptions is discussed under "Long-term Employee Benefits" beginning on page 32 and in Note 17 to the Consolidated Financial Statements.

Environmental Matters DuPont accrues for remediation activities when it is probable that a liability has been incurred and a reasonable estimate of the liability can be made. The company has recorded a liability of $416 million in the Consolidated Balance Sheet as of December 31, 2011 ; these accrued liabilities exclude claims against third parties and are not discounted. As remediation activities vary substantially in duration and cost from site to site, it is difficult to develop precise estimates of future site remediation costs. The company's estimates are based on a number of factors, including the complexity of the geology, the nature and extent of contamination, the type of remedy, the outcome of discussions with regulatory agencies and other PRPs at multi-party sites and the number of and financial viability of other PRPs. Therefore, considerable uncertainty exists with respect to environmental remediation costs and, under adverse changes in circumstances, the potential liability may range up to three times the amount accrued.
Legal Contingencies The company's results of operations could be affected by significant litigation adverse to the company, including product liability claims, patent infringement and antitrust claims, and claims for third party property damage or personal injury stemming from alleged environmental torts. The company records accruals for legal matters when the information available indicates that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Management makes adjustments to these accruals to reflect the impact and status of negotiations, settlements, rulings, advice of counsel and other information and events that may pertain to a particular matter. Predicting the outcome of claims and lawsuits and estimating related costs and exposure involves substantial uncertainties that could cause actual costs to vary materially from estimates. In making determinations of likely outcomes of litigation matters, management considers many factors. These factors include, but are not limited to, the nature of specific claims including unasserted claims, the company's experience with similar types of claims, the jurisdiction in which the matter is filed, input from outside legal counsel, the likelihood of resolving the matter through alternative dispute resolution mechanisms and the matter's current status. Considerable judgment is required in determining whether to establish a litigation accrual when an adverse judgment is rendered against the company in a court proceeding. In such situations, the company will not recognize a loss if, based upon a thorough review of all relevant facts and information, management believes that it is

29Table of Contents
Part II ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS, continued

probable that the pending judgment will be successfully overturned on appeal. A detailed discussion of significant litigation matters is contained in Note 15 to the Consolidated Financial Statements.

Income Taxes The breadth of the company's operations and the global complexity of tax regulations require assessments of uncertainties and judgments in estimating taxes the company will ultimately pay. The final taxes paid are dependent upon many factors, including negotiations with taxing authorities in various jurisdictions, outcomes of tax litigation and resolution of disputes arising from federal, state and international tax audits in the normal course of business. The resolution of these uncertainties may result in adjustments to the company's tax assets and tax liabilities. It is reasonably possible that changes to the company's global unrecognized tax benefits could be significant, however, due to the uncertainty regarding the timing of completion of audits and possible outcomes, a current estimate of the range of increases or decreases that may occur within the next twelve months cannot be made.
Deferred income taxes result from differences between the financial and tax basis of the company's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Significant judgment is required in evaluating the need for and magnitude of appropriate valuation allowances against deferred tax assets. The realization of these assets is dependent on generating future taxable income, as well as successful implementation of various tax planning strategies. For example, changes in facts and circumstances that alter the probability that the company will realize deferred tax assets could result in recording a valuation allowance, thereby reducing the deferred tax asset and generating a deferred tax expense in the relevant period. In some situations these changes could be material.

At December 31, 2011 , the company had a deferred tax asset balance of $8.0 billion, net of valuation allowance of $2.0 billion. Realization of these assets is expected to occur over an extended period of time. As a result, changes in tax laws, assumptions with respect to future taxable income, and tax planning strategies could result in adjustments to these assets. See Note 5 to the Consolidated Financial Statements for additional details related to the deferred tax asset balance.
Valuation of Assets The assets and liabilities of acquired businesses are measured at their estimated fair values at the dates of acquisition. The excess of the purchase price over the estimated fair value of the net assets acquired, including identified intangibles, is recorded as goodwill. The determination and allocation of fair value to the assets acquired and liabilities assumed is based on various assumptions and valuation methodologies requiring considerable management judgment, including estimates based on historical information, current market data and future expectations. The principal assumptions utilized in the company's valuation methodologies include revenue growth rates, operating margin estimates and discount rates. Although the estimates were deemed reasonable by management based on information available at the dates of acquisition, those estimates are inherently uncertain.
Assessment of the potential impairment of property, plant and equipment, goodwill, other intangible assets and investments in affiliates is an integral part of the company's normal ongoing review of operations. Testing for potential impairment of these assets is significantly dependent on numerous assumptions and reflects management's best estimates at a particular point in time. The dynamic economic environments in which the company's diversified businesses operate, and key economic and business assumptions with respect to projected selling prices, market growth and inflation rates, can significantly affect the outcome of impairment tests. Estimates based on these assumptions may differ significantly from actual results. Changes in factors and assumptions used in assessing potential impairments can have a significant impact on the existence and magnitude of impairments, as well as the time in which such impairments are recognized.
Based on the results of the company's annual goodwill impairment test in 2011, no impairments exist at this time. The company's methodology for estimating the fair value of its reporting units is using the income approach based on the present value of future cash flows. The income approach has been generally supported by additional market transaction analyses. There can be no assurance that the company's estimates and assumptions regarding forecasted cash flow and revenue and operating income growth rates made for purposes of the annual goodwill impairment test will prove to be accurate predictions of the future. The company believes the current assumptions and estimates utilized are both reasonable and appropriate.

Off-Balance Sheet Arrangements Certain Guarantee Contracts Information with respect to the company's guarantees is included in Note 15 to the Consolidated Financial Statements. Historically, the company has not had to make significant payments to satisfy guarantee obligations; however, the company believes it has the financial resources to satisfy these guarantees.
Contractual Obligations Information related to the company's significant contractual obligations is summarized in the following table:

Long-term Employee BenefitsThe company has various obligations to its employees and retirees. The company maintains retirement-related programs in many countries that have a longterm impact on the company's earnings and cash flows. These plans are typically defined benefit pension plans, as well as medical, dental and life insurance benefits for pensioners and survivors and disability and life insurance protection for employees (other long-term employee benefits). Approximately 80 percent of the company's worldwide benefit obligation for pensions and essentially all of the company's worldwide other long-term employee benefit obligations are attributable to the U.S. benefit plans. Pension coverage for employees of the company's non-U.S. consolidated subsidiaries is provided, to the extent deemed appropriate, through separate plans. The company regularly explores alternative solutions to meet its global pension obligations in the most cost effective manner possible as demographics, life expectancy and country-specific pension funding rules change. Where permitted by applicable law, the company reserves the right to change, modify or discontinue its plans that provide pension, medical, dental, life insurance and disability benefits.
The majority of employees hired in the U.S. on or after January 1, 2007 are not eligible to participate in the pension and post-retirement medical, dental and life insurance plans, but receive benefits in the defined contribution plans.
Benefits under defined benefit pension plans are based primarily on years of service and employees' pay near retirement. Pension benefits are paid primarily from trust funds established to comply with applicable laws and regulations. Unless required by law, the company does not make contributions that are in excess of tax deductible limits. The actuarial assumptions and procedures utilized are reviewed periodically by the plans' actuaries to provide reasonable assurance that there will be adequate funds for the payment of benefits. The co mpany made a contribution of $500 million in 2010 to its principal U.S. pension plan and no contributions were made in 2011. In January 2012, the company contributed $500 million to its principal U.S. pension plan. The company expects to make contributions to its principal U.S. pension plan beyond 2012; however, the amount of any contributions is heavily dependent on the future economic environment and investment returns on pension trust assets. U.S. pension benefits that exceed federal limitations are covered by separate unfunded plans and these benefits are paid to pensioners and survivors from operating cash flows. Funding for each pension plan is governed by the rules of the sovereign country in which it operates. Thus, there is not necessarily a direct correlation between pension funding and pension expense. In general, however, improvements in plans funded status tends to moderate subsequent funding needs. The company contributed $341 million to its pension plans in 2011 and anticipates that it will make approximately $345 million in contributions in 2012 to pension plans other than the principal U.S. pension plan.
The company's other long-term employee benefits are unfunded and the cost of the approved claims is paid from operating cash flows. Pre-tax cash requirements to cover actual net claims costs and related administrative expenses were $312 million, $321 million and $323 million for 2011, 2010 and 2009, respectively. This amount is expected to be about $315 million in 2012. Changes in cash requirements reflect the net impact of higher per capita health care costs, demographic changes and changes in participant premiums, co-pays and deductibles.
The company's income can be significantly affected by pension and defined contribution benefits as well as other long-term employee benefits. The following table summarizes the extent to which the company's income over each of the last 3 years was affected by pre-tax charges related to long-term employee benefits:

(Dollars in millions) 2011 2010 2009 Defined benefit plan charges $ 656 $ 557 $ 155 Defined contribution plan charges 294 254 245 Other long-term employee benefit plan charges 184 219 220 $ 1,134 $ 1,030 $ 620
The above charges for pension and other long-term employee benefits are determined as of the beginning of each year. The increase in pension expense in 2011 is primarily related to the decrease in discount rates and the increase in pension expense in 2010 is primarily related to decreases in the market-related value of the assets in the principal U.S. pension plan. See "Long-term Employee Benefits" under the Critical Accounting Estimates section beginning on page 28 of this report for additional information on determining annual expense for the principal U.S. pension plan.
The company's key assumptions used in calculating its pension and other long-term employee benefits are the expected return on plan assets, the rate of compensation increases and the discount rate (see Note 17 to the Consolidated Financial Statements). For

2012, long-term employee benefits expense is expected to increase by about $225 million, primarily due to lower discount rates.

Environmental Matters The company operates global manufacturing, product handling and distribution facilities that are subject to a broad array of environmental laws and regulations. Such rules are subject to change by the implementing governmental agency, and the company monitors these changes closely. Company policy requires that all operations fully meet or exceed legal and regulatory requirements. In addition, the company implements voluntary programs to reduce air emissions, minimize the generation of hazardous waste, decrease the volume of water use and discharges, increase the efficiency of energy use and reduce the generation of persistent, bioaccumulative and toxic materials. Management has noted a global upward trend in the amount and complexity of proposed chemicals regulation. The costs to comply with complex environmental laws and regulations, as well as internal voluntary programs and goals, are significant and will continue to be significant for the foreseeable future.
Pre-tax environmental expenses charged to current operations are summarized below:

(Dollars in millions) 2011 2010 2009 Environmental operating costs $ 587 $ 551 $ 528 Increase in remediation accrual 92 93 89 $ 679 $ 644 $ 617
About 75 percent of total pre-tax environmental expenses charged to current operations in 2011 resulted from operations in the U.S. The increases in total pretax environmental expenses charged to operations were due primarily to acquired businesses and increased environmental research activities. Based on existing facts and circumstances, management does not believe that year over year changes, if any, in environmental expenses charged to current operations will have a material impact on the company's financial position, liquidity or results of operations.
Environmental Operating Costs As a result of its operations, the company incurs costs for pollution abatement activities including waste collection and disposal, installation and maintenance of air pollution controls and wastewater treatment, emissions testing and monitoring, and obtaining permits. The company also incurs costs related to environmental related research and development activities including environmental field and treatment studies as well as toxicity and degradation testing to evaluate the environmental impact of products and raw materials.

Remediation Accrual Changes in the remediation accrual balance are summarized below:

(Dollars in millions) Balance at December 31, 2009 $ 396 Remediation payments (82 ) Increase in remediation accrual 93 Balance at December 31, 2010 $ 407 Remediation payments (83 ) Increase in remediation accrual 92 Balance at December 31, 2011 $ 416
Annual expenditures are expected to continue to increase in the near future; however, they are not expected to vary significantly from the range of such expenditures experienced in the past few years. Longer term, expenditures are subject to considerable uncertainty and may fluctuate significantly.
As of December 31, 2011, the company has been notified of potential liability under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA or Superfund) or similar state laws at about 410 sites around the U.S., with active remediation under way at approximately 160 of these sites. In addition, the company has resolved its liability at approximately 170 sites, either by completing remedial actions with other PRPs or by participating in "de minimis buyouts" with other PRPs whose waste, like the company's, represented only a small fraction of the total waste present at a site. The company received notice of potential liability at six new sites during 2011 compared with ten and three similar notices in 2010 and 2009, respectively.

33Table of Contents
Part II ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS, continued

Considerable uncertainty exists with respect to environmental remediation costs, and, under adverse changes in circumstances, potential liability may range up to three times the amount accrued as of December 31, 2011. However, based on existing facts and circumstances, management does not believe that any loss, in excess of amounts accrued, related to remediation activities at any individual site will have a material impact on the financial position, liquidity or results of operations of the company.
Environmental Capital Expenditures In 2011, the company spent approximately $85 million on environmental capital projects either required by law or necessary to meet the company's internal environmental goals. The company currently estimates expenditures for environmental-related capital projects to be approximately $110 million in 2012. In the U.S., additional capital expenditures are expected to be required over the next decade for treatment, storage and disposal facilities for solid and hazardous waste and for compliance with the Clean Air Act (CAA). Until all CAA regulatory requirements are established and known, considerable uncertainty will remain regarding estimates for future capital expenditures. However, management does not believe that the costs to comply with these requirements will have a material impact on the financial position or liquidity of the company.
Climate Change The company believes that climate change is an important global issue that presents risks and opportunities. The company has made its overall portfolio less energy and emissions intensive, reducing 2010 absolute energy use by 6 percent since 1990 while significantly increasing production. In addition, the company sourced 6 percent of 2010 total energy use from renewable resources. The company continuously evaluates opportunities for existing and new product and service offerings in light of the anticipated demands of a low-carbon economy. About $1.6 billion of the company's 2010 revenue was generated from sales of products that help direct and downstream customers reduce greenhouse gas (GHG) emissions.
The company has achieved major global reductions in GHG emissions since it began taking action in the early 1990's. The company is actively engaged in the effort to develop constructive public policies to reduce GHG emissions and encourage lower carbon forms of energy. Proposed and existing legislative efforts to control or limit GHG emissions could affect the company's energy source and supply choices as well as increase the cost of energy and raw materials derived from fossil fuels. Such efforts are also anticipated to provide the business community with greater certainty for the regulatory future, help guide investment decisions, and drive growth in demand for low-carbon and energy-efficient products, technologies, and services.
At the national and regional level, there are existing efforts to address climate change. Several of the company's facilities in the European Union (EU) are regulated under the EU Emissions Trading Scheme. In other countries, including the U.S., policy debate continues. The current unsettled policy environment in the U.S. adds an element of uncertainty to business decisions particularly those relating to long-term capital investments. If in the absence of federal legislation, states were to implement programs mandating GHG emissions reductions, the company, its suppliers and customers could be competitively disadvantaged by the added administrative costs of complying with a variety of state-specific requirements.
In 2010, EPA launched a phased-in scheme to regulate GHG emissions first from large stationary sources under CAA permitting requirements administered by state and local authorities. As a result, large capital investments may be required to install Best Available Control Technology on major new or modified sources of GHG emissions. This type of GHG emissions regulation by EPA, in the absence of or in addition to federal legislation, could result in more costly, less efficient facility-by-facility controls versus a federal, market-based cap and trade program. Differences in regional or national legislation could present challenges in a global marketplace highlighting the need for coordinated global policy action.
Registration The European Union's regulatory framework concerning the Registration, Evaluation and Authorization of Chemicals (REACH) entered into force in 2007 and requires manufacturers and importers to gather and register information on the properties of their substances that meet certain volume or toxicological criteria. The company has successfully integrated REACH registration requirements into its safety, health & environment processes and timely met all such requirements to date. REACH also contains a mechanism for the progressive substitution of the most dangerous chemicals when suitable alternatives have been identified. Depending on which chemicals are identified, the requirement to use safer alternatives could necessitate changes in production processes.

PFOA The Performance Chemicals segment uses a form of PFOA (collectively, perfluorooctanoic acid and its salts, including the ammonium salt) as a processing aid to manufacture fluoropolymer resins and dispersions. The Performance Materials segment uses PFOA in the manufacture of raw materials for perfluoroelastomer parts and some fluoroelastomers. In the fall of 2002, DuPont began producing rather than purchasing PFOA to support these manufacturing processes. PFOA is not used in the manufacture of fluorotelomers; however, it is an unintended by-product present at trace levels in some fluorotelomer-based products.
PFOA is bio-persistent and has been detected at very low levels in the blood of the general population. As a result, EPA initiated a process to enhance its understanding of the sources of PFOA in the environment and the pathways through which human exposure to PFOA is occurring. In 2005, EPA issued a draft risk assessment on PFOA stating that the cancer data for PFOA may be best described as "suggestive evidence of carcinogenicity, but not sufficient to assess human carcinogenic potential" under EPA's Guidelines for Carcinogen Risk Assessment. The EPA risk assessment is ongoing. Although EPA has stated that there remains considerable scientific uncertainty regarding potential risks associated with PFOA, it also stated that it does not believe that there is any reason for consumers to stop using any products because of concerns about PFOA.
DuPont respects EPA's position raising questions about exposure routes and the potential toxicity of PFOA and DuPont and other companies have outlined plans to continue research, emission reduction and product stewardship activities to help address EPA's questions. In January 2006, DuPont pledged its commitment to EPA's 2010/15 PFOA Stewardship Program. The EPA program asks participants (1) to commit to achieve, no later than 2010, a 95 percent reduction in both facility emissions and product content levels of PFOA, PFOA precursors and related higher homologue chemicals and (2) to commit to working toward the elimination of PFOA, PFOA precursors and related higher homologue chemicals from emissions and products by no later than 2015. DuPont has exceeded the EPA's 2010 objective. In February 2007, DuPont announced its commitment to no longer make, use or buy PFOA by 2015, or sooner if possible. To achieve this goal, DuPont developed PFOA replacement technology and is converting customers to fluoropolymer resins and dispersions manufactured using the replacement technology. DuPont has been introducing its next generation fluorotelomers products and converting customers to their use.
In 2009, EPA issued a national Provisional Health Advisory for PFOA of 0.4 parts per billion (ppb) in drinking water. In 2007, NJDEP identified a preliminary drinking-water guidance level for PFOA of 0.04 ppb as part of the first phase of an ongoing process to establish a state drinking-water standard.
For additional information regarding PFOA matters, see Note 15 to the Consolidated Financial Statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Derivatives and Other Hedging Instruments In the ordinary course of business, the company enters into contractual arrangements (derivatives) to hedge its exposure to foreign currency, interest rate and commodity price risks under established procedures and controls. For additional information on these derivatives and related exposures, see Note 19 to the Consolidated Financial Statements.
The following table summarizes the impacts of the company's foreign currency hedging program on the company's results of operations for the years ended December 31, 2011, 2010 and 2009, and includes the company's pro rata share of its equity affiliates' exchange gains and losses and corresponding gains and losses on foreign currency exchange contracts:

(Dollars in millions) 2011 2010 2009 Pre-tax exchange loss $ (163 ) $ (13 ) $ (205 ) Tax benefit (expense) 82 (71 ) 91 After-tax exchange loss $ (81 ) $ (84 ) $ (114 )
In addition to the contracts disclosed in Note 19 to the Consolidated Financial Statements, from time to time, the company will enter into foreign currency exchange contracts to establish with certainty the USD amount of future firm commitments denominated in a foreign currency. Decisions regarding whether or not to hedge a given commitment are made on a case-by-case basis, taking into consideration the amount and duration of the exposure, market volatility and economic trends. Foreign currency exchange contracts are also used, from time to time, to manage near-term foreign currency cash requirements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK, continued Sensitivity Analysis The following table illustrates the fair values of outstanding derivative contracts at December 31, 2011 and 2010, and the effect on fair values of a hypothetical adverse change in the market prices or rates that existed at December 31, 2011 and 2010. The sensitivity for interest rate swaps is based on a one percent change in the market interest rate. Foreign currency and commodity contracts sensitivities are based on a 10 percent change in market rates.

Since the company's risk management programs are highly effective, the potential loss in value for each risk management portfolio described above would be largely offset by changes in the value of the underlying exposure.

Concentration of Credit Risk The company maintains cash and cash equivalents, marketable securities, derivatives and certain other financial instruments with various financial institutions. These financial institutions are generally highly rated and geographically dispersed and the company has a policy to limit the dollar amount of credit exposure with any one institution.
As part of the company's financial risk management processes, it continuously evaluates the relative credit standing of all of the financial institutions that service DuPont and monitors actual exposures versus established limits. The company has not sustained credit losses from instruments held at financial institutions.
The company's sales are not materially dependent on any single customer. As of December 31, 2011, no one individual customer balance represented more than 5 percent of the company's total outstanding receivables balance. Credit risk associated with its receivables balance is representative of the geographic, industry and customer diversity associated with the company's global businesses.
The company also maintains strong credit controls in evaluating and granting customer credit. As a result, it may require that customers provide some type of financial guarantee in certain circumstances. Length of terms for customer credit varies by industry and region.

ITEM 9A. CONTROLS AND PROCEDURES
The company maintains a system of disclosure controls and procedures to give reasonable assurance that information required to be disclosed in the company's reports filed or submitted under the Securities Exchange Act of 1934 (Exchange Act) is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. These controls and procedures also give reasonable assurance that information required to be disclosed in such reports is accumulated and communicated to management to allow timely decisions regarding required disclosures.
As of December 31, 2011, the company's Chief Executive Officer (CEO) and Chief Financial Officer (CFO), together with management, conducted an evaluation of the effectiveness of the company's disclosure controls and procedures pursuant to Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based on that evaluation, the CEO and CFO concluded that these disclosure controls and procedures are effective.
There has been no change in the company's internal control over financial reporting that occurred during the fourth quarter of 2011 that has materially affected, or is reasonably likely to materially affect, the company's internal control over financial reporting. The company has completed its evaluation of its internal controls and has concluded that the company's system of internal controls over financial reporting was effective as of December 31, 2011 (see page F-2).

Management's Report on Responsibility for Financial Statements

Management is responsible for the Consolidated Financial Statements and the other financial information contained in this Annual Report on Form 10-K. The financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (GAAP) and are considered by management to present fairly the company's financial position, results of operations and cash flows. The financial statements include some amounts that are based on management's best estimates and judgments. The financial statements have been audited by the company's independent registered public accounting firm, PricewaterhouseCoopers LLP. The purpose of their audit is to express an opinion as to whether the Consolidated Financial Statements included in this Annual Report on Form 10-K present fairly, in all material respects, the company's financial position, results of operations and cash flows in conformity with GAAP. Their report is presented on the following page.

Management's Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining an adequate system of internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The 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 GAAP. The company's internal control over financial reporting includes those policies and procedures that:

i. pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the

assets of the company;
ii. 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 authorization of management and directors of the company; and
iii. provide reasonable assurance regarding prevention or timely detection of unauthorized acquisitions, use or disposition of the

company's assets that could have a material effect on the financial statements. Internal control over financial reporting has certain inherent limitations which may not prevent or detect misstatements. In addition, changes in conditions and business practices may cause variation in the effectiveness of internal controls.

Management assessed the effectiveness of the company's internal control over financial reporting as of December 31, 2011, based on criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework . Based on its assessment and those criteria, management concluded that the company maintained effective internal control over financial reporting as of December 31, 2011.

PricewaterhouseCoopers LLP, an independent registered public accounting firm, has audited the effectiveness of the company's internal control over financial reporting as of December 31, 2011, as stated in their report, which is presented on the following page.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of E. I. du Pont de Nemours and Company: In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, equity and cash flows present fairly, in all material respects, the financial position of E. I. du Pont de Nemours and Company and its subsidiaries at December 31, 2011 and 2010, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2011 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a) (2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in "Management's Report on Internal Control over Financial Reporting" appearing on page F-2. Our responsibility is to express opinions on these financial statements, on the financial statement schedule and on the Company's internal control over financial reporting based on our integrated 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 audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe our audits provide a reasonable basis for our opinions.

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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) 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.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The company follows generally accepted accounting principles in the United States of America (GAAP). The significant accounting policies described below, together with the other notes that follow, are an integral part of the Consolidated Financial Statements.
Preparation of Financial Statements The preparation of financial statements in conformity with GAAP requires management 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.

Basis of Consolidation The Consolidated Financial Statements include the accounts of the company, subsidiaries in which a controlling interest is maintained and variable interest entities (VIEs) for which DuPont is the primary beneficiary. For those consolidated subsidiaries in which the company's ownership is less than 100 percent, the outside stockholders' interests are shown as noncontrolling interests. Investments in affiliates over which the company has significant influence but not a controlling interest are carried on the equity basis. At December 31, 2011, the assets, liabilities and operations of VIEs for which DuPont is the primary beneficiary were not material to the Consolidated Financial Statements of the company.
The company is also involved with certain joint ventures accounted for under the equity method of accounting that are VIEs. The company is not the primary beneficiary, as the nature of the company's involvement with the VIEs does not provide it the power to direct the VIEs significant activities. Future events may require these VIEs to be consolidated if the company becomes the primary beneficiary. At December 31, 2011, the maximum exposure to loss related to the unconsolidated VIEs is not considered material to the Consolidated Financial Statements of the company.
Revenue Recognition The company recognizes revenue when the earnings process is complete. The company's revenues are from the sale of a wide range of products to a diversified base of customers around the world. Revenue for product sales is recognized upon delivery, when title and risk of loss have been transferred, collectability is reasonably assured and pricing is fixed or determinable. Substantially all product sales are sold FOB (free on board) shipping point or, with respect to non United States of America (U.S.) customers, an equivalent basis. Accruals are made for sales returns and other allowances based on the company's experience. The company accounts for cash sales incentives as a reduction in sales and noncash sales incentives as a charge to cost of goods sold or selling expense, depending on the nature of the incentive. Amounts billed to customers for shipping and handling fees are included in net sales and costs incurred by the company for the delivery of goods are classified as cost of goods sold and other operating charges in the Consolidated Income Statements. Taxes on revenue-producing transactions are excluded from net sales.
The company periodically enters into prepayment contracts with customers in the Agriculture segment and receives advance payments for product to be delivered in future periods. These advance payments are recorded as deferred revenue (classified as other accrued liabilities) or debt, depending on the nature of the program. Revenue associated with advance payments is recognized as shipments are made and title, ownership and risk of loss pass to the customer.
Licensing and royalty income is recognized in accordance with agreed upon terms, when performance obligations are satisfied, the amount is fixed or determinable and collectability is reasonably assured.
Cash and Cash Equivalents Cash equivalents represent investments with maturities of three months or less from time of purchase. They are carried at cost plus accrued interest, which approximates fair value because of the short-term maturity of these instruments.

Marketable Securities Marketable securities represent investments in fixed and floating rate financial instruments with maturities greater than three months and up to twelve months at time of purchase. They are classified as held-to-maturity and recorded at amortized cost. The carrying value approximates fair value due to the short-term nature of the investments.

Fair Value Measurements Under the accounting for fair value measurements and disclosures, a fair value hierarchy was established that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active

F-8Table of Contents E. I. du Pont de Nemours and Company Notes to the Consolidated Financial Statements (continued)

(Dollars in millions, except per share) markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.
The company uses the following valuation techniques to measure fair value for its assets and liabilities:

Level 1

– Quoted market prices in active markets for identical assets or liabilities;

Level 2

– Significant other observable inputs (e.g. quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs other than quoted prices that are observable such as interest rate and yield curves, and market-corroborated inputs);

Level 3

– Unobservable inputs for the asset or liability, which are valued based on management's estimates of assumptions that market participants would use in pricing the asset or liability.

Inventories The majority of the company's inventories are valued at cost, as determined by the last-in, first-out (LIFO) method; in the aggregate, such valuations are not in excess of market. Seed, certain food-ingredient and enzyme inventories are valued at the lower of cost, as determined by the first-in, first-out (FIFO) method, or market.
Elements of cost in inventories include raw materials, direct labor and manufacturing overhead. Stores and supplies are valued at cost or market, whichever is lower; cost is generally determined by the average cost method.
Property, Plant and Equipment Property, plant and equipment is carried at cost and is depreciated using the straight-line method. Property, plant and equipment placed in service prior to 1995 is depreciated under the sum-of-the-years' digits method or other substantially similar methods. Substantially all equipment and buildings are depreciated over useful lives ranging from 15 to 25 years. Capitalizable costs associated with computer software for internal use are amortized on a straightline basis over 5 to 7 years. When assets are surrendered, retired, sold or otherwise disposed of, their gross carrying values and related accumulated depreciation are removed from the accounts and included in determining gain or loss on such disposals.
Maintenance and repairs are charged to operations; replacements and improvements are capitalized.
Goodwill and Other Intangible Assets Goodwill represents costs in excess of fair values assigned to underlying net assets of acquired companies. Goodwill and indefinite-lived intangible assets are tested for impairment at least annually; however, these tests are performed more frequently when events or changes in circumstances indicate that the asset may be impaired. The company's fair value methodology is based on prices of similar assets or other valuation methodologies including discounted cash flow techniques. Impairment losses are included in cost of goods sold and other operating charges.
Definite-lived intangible assets, such as purchased and licensed technology, patents and customer lists are amortized over their estimated useful lives, generally for periods ranging from 1 to 20 years. The company continually evaluates the reasonableness of the useful lives of these assets. Once these assets are fully amortized, they are removed from the Consolidated Balance Sheets.
Impairment of Long-Lived Assets The company evaluates the carrying value of long-lived assets to be held and used when events or changes in circumstances indicate the carrying value may not be recoverable. The carrying value of a long-lived asset is considered impaired when the total projected undiscounted cash flows from the asset are separately identifiable and are less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset. The company's fair value methodology is an estimate of fair market value which is made based on prices of similar assets or other valuation methodologies including present value techniques. Long-lived assets to be disposed of other than by sale are classified as held for use until their disposal. Long-lived assets to be disposed of by sale are classified as held for sale and are reported at the lower of carrying amount or fair market value less cost to sell. Depreciation is discontinued for long-lived assets classified as held for sale.
Research and Development Research and development costs are expensed as incurred.

Environmental Accruals for environmental matters are recorded in operating expenses when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Accrued liabilities do not include claims against third parties and are not discounted.
Costs related to environmental remediation and restoration are charged to expense. Other environmental costs are also charged to expense unless they increase the value of the property or reduce or prevent contamination from future operations, in which case, they are capitalized.
Asset Retirement Obligations The company records asset retirement obligations at fair value at the time the liability is incurred. Accretion expense is recognized as an operating expense using the credit-adjusted risk-free interest rate in effect when the liability was recognized. The associated asset retirement obligations are capitalized as part of the carrying amount of the long-lived asset and depreciated over the estimated remaining useful life of the asset, generally for periods ranging from 1 to 25 years.
Litigation The company accrues for liabilities related to litigation matters when the information available indicates that it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Legal costs such as outside counsel fees and expenses are charged to expense in the period incurred.

Insurance/Self-Insurance The company self-insures certain risks where permitted by law or regulation, including workers' compensation, vehicle liability and employee related benefits. Liabilities associated with these risks are estimated in part by considering historical claims experience, demographic factors and other actuarial assumptions. For other risks, the company uses a combination of insurance and self-insurance, reflecting comprehensive reviews of relevant risks. A receivable for an insurance recovery is generally recognized when the loss has occurred and collection is considered probable.

Income Taxes The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax basis of the company's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Provision has been made for income taxes on unremitted earnings of subsidiaries and affiliates, except for subsidiaries in which earnings are deemed to be indefinitely invested. Investment tax credits or grants are accounted for in the period earned (the flow-through method). Interest accrued related to unrecognized tax benefits is included in miscellaneous income and expenses, net, under other income, net. Income tax related penalties are included in the provision for income taxes.
Foreign Currency Translation The U.S. dollar (USD) is the functional currency of most of the company's worldwide operations. For subsidiaries where the USD is the functional currency, all foreign currency asset and liability amounts are remeasured into USD at end-of-period exchange rates, except for inventories, prepaid expenses, property, plant and equipment, goodwill and other intangible assets, which are remeasured at historical rates. Foreign currency income and expenses are remeasured at average exchange rates in effect during the year, except for expenses related to balance sheet amounts remeasured at historical exchange rates. Exchange gains and losses arising from remeasurement of foreign currency-denominated monetary assets and liabilities are included in income in the period in which they occur.
For subsidiaries where the local currency is the functional currency, assets and liabilities denominated in local currencies are translated into USD at end-ofperiod exchange rates and the resultant translation adjustments are reported, net of their related tax effects, as a component of accumulated other comprehensive income (loss) in equity. Assets and liabilities denominated in other than the local currency are remeasured into the local currency prior to translation into USD and the resultant exchange gains or losses are included in income in the period in which they occur. Income and expenses are translated into USD at average exchange rates in effect during the period.

F-10Table of Contents E. I. du Pont de Nemours and Company Notes to the Consolidated Financial Statements (continued)

(Dollars in millions, except per share) Hedging and Trading Activities Derivative instruments are reported in the Consolidated Balance Sheets at their fair values. For derivative instruments designated as fair value hedges, changes in the fair values of the derivative instruments will generally be offset in the income statement by changes in the fair value of the hedged items. For derivative instruments designated as cash flow hedges, the effective portion of any hedge is reported in accumulated other comprehensive income (loss) until it is cleared to earnings during the same period in which the hedged item affects earnings. The ineffective portion of all hedges is recognized in current period earnings. Changes in the fair values of derivative instruments that are not designated as hedges are recorded in current period earnings.
In the event that a derivative designated as a hedge of a firm commitment or an anticipated transaction is terminated prior to the maturation of the hedged transaction, gains or losses realized at termination are deferred and included in the measurement of the hedged transaction. If a hedged transaction matures, or is sold, extinguished, or terminated prior to the maturity of a derivative designated as a hedge of such transaction, gains or losses associated with the derivative through the date the transaction matured are included in the measurement of the hedged transaction and the derivative is reclassified as for trading purposes. Derivatives designated as a hedge of an anticipated transaction are reclassified as for trading purposes if the anticipated transaction is no longer probable.
Cash flows from derivative instruments accounted for as either fair value hedges or cash flow hedges are reported in the same category as the cash flows from the items being hedged. Cash flows from all other derivative instruments are generally reported as investing activities in the Consolidated Statements of Cash Flows. See Note 19 for additional discussion regarding the company's objectives and strategies for derivative instruments.

Reclassifications Certain reclassifications of prior years' data have been made to conform to 2011 classifications.
Recent Accounting Pronouncements In May 2011, the Financial Accounting Standards Board (FASB) issued authoritative guidance on fair value measurements and disclosures which becomes effective for interim and annual periods beginning after December 15, 2011. The new guidance enhances disclosures and refines certain aspects of fair value measurement that primarily affect financial instruments. The adoption of this guidance is not expected to have a material effect on the company's financial position or results of operations.
In June 2011, the FASB issued amendments to the presentation of comprehensive income which becomes effective for interim and annual periods beginning after December 15, 2011. The amendments eliminate the current reporting option of displaying components of other comprehensive income within the statement of changes in stockholders' equity. Under the new guidance, the company expects to present an income statement immediately followed by a statement of comprehensive income.

2. DANISCO ACQUISTION In January 2011, DuPont and its wholly owned subsidiary, DuPont Denmark Holding ApS (DDHA), entered into a definitive agreement with Danisco A/S (Danisco), a global enzyme and specialty food ingredients company, for DDHA to make a public tender offer for all of Danisco's outstanding shares at a price of 665 Danish Kroner (DKK) in cash per share. On April 29, 2011, DDHA increased the price of its tender offer to acquire all of the outstanding shares of Danisco to DKK 700 in cash per share.
On May 19, 2011, the company acquired approximately 92.2 percent of Danisco's outstanding shares, excluding treasury shares, pursuant to the previously announced tender offer. From May 19, 2011 to September 22, 2011, DuPont acquired all of Danisco's remaining outstanding shares. This acquisition has established DuPont as a leader in industrial biotechnology with science-intensive innovations that address global challenges in food production and reduced fossil fuel consumption. The Danisco acquisition was valued at $6,417 , plus net debt assumed of $617 .
As part of the Danisco acquisition, DuPont incurred $85 in transaction related costs during 2011, which were recorded in costs of goods sold and other operating charges. In 2011, Danisco contributed net sales of $1,713 and net income attributable to DuPont of $(7) , which excludes $30 after-tax ($39 pre-tax) of additional interest expense related to the debt issued to finance the acquisition. Danisco's contributions included a $125 after-tax ( $175 pre-tax) charge related to the fair value step-up of inventories acquired and sold during 2011.

F-11Table of Contents E. I. du Pont de Nemours and Company Notes to the Consolidated Financial Statements (continued)

(Dollars in millions, except per share) The following unaudited pro forma summary presents DuPont's consolidated results of operations as if Danisco had been acquired on January 1, 2010. These amounts were calculated after conversion from International Financial Reporting Standards to GAAP and adjusting Danisco's results to reflect the additional depreciation and amortization that would have been charged assuming the fair value adjustments to property, plant and equipment, and intangible assets had been applied from January 1, 2010, together with the consequential tax effects. These adjustments also reflect the additional interest expense incurred on the debt to finance the purchase. The 2011 pro forma earnings were adjusted to exclude the acquisition related costs incurred in 2011 and the nonrecurring expense related to the fair value inventory step-up adjustment. The 2010 pro forma earnings were adjusted to include these charges. The pro forma financial information presented below is for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition and borrowings undertaken to finance the acquisition had taken place at the beginning of 2010.
Pro forma for the year ended December 31,
2011 2010 Net sales $ 39,182 $ 34,203 Net income attributable to DuPont 3,724 2,942
The following table summarizes the fair value of the assets acquired and liabilities assumed as of the acquisition date:
Fair value of assets acquired Cash and cash equivalents $ 48 Accounts and notes receivable 1 522

Inventories 2 709 Property, plant and equipment 1,709 Goodwill 3 2,891 Other intangible assets 4 2,859 Other current and non-current assets 78 Total assets acquired $ 8,816 Fair value of liabilities assumed Accounts payable and other accrued liabilities $ 489

Short-term borrowings 5 342 Long-term borrowings 5 323 Other liabilities 219 Deferred income taxes 6 1,026 Total liabilities assumed $ 2,399

1. The gross amount of accounts and notes receivable acquired was $531, of which $9 was expected to be uncollectible.
2. The fair value of inventories acquired included a step-up in the value of $175 , which was expensed to cost of goods sold and other operating charges in 2011.
3. Goodwill will not be deductible for statutory tax purposes. Goodwill is attributable to Danisco's workforce and the synergies in technology, operations and market access that are expected from the acquisition. Approximately $900 and $2,000 of goodwill was allocated to the Industrial Biosciences and Nutrition & Health segments, respectively. 4. Other intangible assets acquired of $1,002 are indefinite-lived (see Note 10).
5. Debt assumed has been paid off as of December 31, 2011.
6. The deferred income tax liabilities assumed represent the adjustments for the tax impact of fair value adjustments, primarily relating to definite-lived intangible assets.

1. The company routinely uses foreign currency exchange contracts to offset its net exposures, by currency, related to the foreign currency-denominated monetary assets and liabilities. The objective of this program is to maintain an approximately balanced position in foreign currencies in order to minimize, on an after-tax basis, the effects of exchange rate changes on net monetary asset positions. The net pre-tax exchange gains and losses are recorded in other income, net and the related tax impact is recorded in provision for income taxes on the Consolidated Income Statements. Exchange gains (losses) related to earnings of affiliates was $1, $(2) and $13 for 2011, 2010 and 2009, respectively. 2. Miscellaneous income and expenses, net, generally includes interest items, insurance recoveries, litigation settlements and other items.

4. EMPLOYEE SEPARATION/ASSET RELATED CHARGES, NET At December 31, 2011 , total liabilities relating to restructuring activities were $61 , primarily relating to the 2011 restructuring program.
2011 Restructuring Program In 2011, the company initiated a series of actions to achieve the expected cost synergies associated with the Danisco acquisition. As a result, the company recorded a $53 charge in employee separation/asset related charges, net, primarily for employee separation costs in the U.S. and Europe. This charge reduced segment earnings as follows: Industrial Biosciences - $9 , Nutrition & Health - $14 , and Other - $30 . The company expects this initiative and all related payments to be substantially complete in 2013.
Account balances and activity for the 2011 restructuring program are summarized below:
Net charges to income in 2011 $ 53 Payments (4 ) Net translation adjustment (1 ) Balance as of December 31, 2011 $ 48

(Dollars in millions, except per share) Consolidated income before income taxes for U.S. and international operations was as follows:

2011 2010 2009 U.S. (including exports) $ 860 $ 949 $ 171 International 3,422 2,762 2,013 $ 4,282 $ 3,711 $ 2,184
The decrease in U.S. pre-tax earnings from 2010 to 2011 is primarily driven by the results of the company's hedging program. In 2010, the U.S. recorded $117 of exchange gains associated with the hedging program, however, in 2011, the program resulted in the company recording $133 of exchange losses. This swing in the exchange gains and losses year over year offsets underlying recovery in the U.S. economy. While the taxation of the amounts reflected on the chart above does not correspond precisely to the jurisdiction of taxation (due to taxation in multiple countries, exchange gains/losses, etc.), it represents a reasonable approximation of the income before income taxes split between U.S. and international jurisdictions. See Note 19 for additional information regarding the company's hedging program.
Under the tax laws of various jurisdictions in which the company operates, deductions or credits that cannot be fully utilized for tax purposes during the current year may be carried forward or back, subject to statutory limitations, to reduce taxable income or taxes payable in future or prior years. At December 31, 2011, the tax effect of such carryforwards/backs, net of valuation allowance approximated $1,428 . Of this amount, $1,204 has no expiration date, $70 expires after 2011 but before the end of 2016 and $154 expires after 2016.

At December 31, 2011, unremitted earnings of subsidiaries outside the U.S. totaling $13,350 were deemed to be indefinitely reinvested. No deferred tax liability has been recognized with regard to the remittance of such earnings. It is not practical to estimate the income tax liability that might be incurred if such earnings were remitted to the U.S.
Each year the company files hundreds of tax returns in the various national, state and local income taxing jurisdictions in which it operates. These tax returns are subject to examination and possible challenge by the taxing authorities. Positions challenged by the taxing authorities may be settled or appealed by the company. As a result, there is an uncertainty in income taxes recognized in the company's financial statements in accordance with accounting for income taxes and accounting for uncertainty in income taxes. It is reasonably possible that changes to the company's global unrecognized tax benefits could be significant, however, due to the uncertainty regarding the timing of completion of audits and possible outcomes, a current estimate of the range of increases or decreases that may occur within the next twelve months cannot be made.

(Dollars in millions, except per share) The company and/or its subsidiaries files income tax returns in the U.S. federal jurisdiction, and various states and non-U.S. jurisdictions. With few exceptions, the company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 1999. A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows:

2011 2010 2009 Total unrecognized tax benefits as of January 1 $ 693 $ 739 $ 677 Gross amounts of decreases in unrecognized tax benefits as a result of tax positions taken during the prior period (82 ) (155 ) (60 )

6. EARNINGS PER SHARE OF COMMON STOCK Set forth below is a reconciliation of the numerator and denominator for basic and diluted earnings per share calculations for the periods indicated:

2011 2010 2009 Numerator: Net income attributable to DuPont $ 3,474 $ 3,031 $ 1,755 Preferred dividends (10 ) (10 ) (10 ) Net income available to common stockholders $ 3,464 $ 3,021 $ 1,745 Denominator: Weighted-average number of common shares outstanding – Basic 928,417,000 908,860,000 904,395,000 Dilutive effect of the company's employee compensation plans 12,612,000 12,795,000 4,317,000 Weighted average number of common shares outstanding – Diluted 941,029,000 921,655,000 908,712,000
The weighted-average number of common shares outstanding in 2011 and 2010 increased as a result of the issuance of new shares from the company's equity compensation plans, partially offset by the company's repurchase and retirement of its common stock (see Note 16).
The following average number of stock options are antidilutive and therefore, are not included in the diluted earnings per share calculation:

2011 2010 2009 Average number of stock options 4,361,000 45,508,000 72,899,000
The change in the average number of stock options that were antidilutive in 2011 and 2010 was primarily due to changes in the company's average stock price.

1. Accounts and notes receivable – trade are net of allowances of $292 in 2011 and $326 in 2010 . Allowances are equal to the estimated uncollectible amounts. That estimate is based on historical collection experience, current economic and market conditions, and review of the current status of customer's accounts. 2. Notes receivable – trade primarily consists of receivables within the Agriculture segment for deferred payment loan programs for the sale of seed products to customers. These loans have terms of one year or less and are primarily concentrated in North America. The company maintains a rigid pre-approval process for extending credit to customers in order to manage overall risk and exposure associated with credit losses. As of December 31, 2011 and 2010 , there were no significant past due notes receivable, nor were there any significant impairments related to current loan agreements. 3. Other includes receivables in relation to Cozaar ® /Hyzaar ® interests, fair value of derivative instruments, value added tax, general sales tax and other taxes. Accounts and notes receivable are carried at amounts that approximate fair value.

Inventory values, before LIFO adjustment, are generally determined by the average cost method, which approximates current cost. Excluding seeds, certain food-ingredients, enzymes, stores and supplies, inventories valued under the LIFO method comprised 78 percent of consolidated inventories before LIFO adjustment as of December 31, 2011 and 2010 . Seed, certain food-ingredient and enzyme inventories of $3,432 and $2,581 at December 31, 2011 and 2010, respectively, were valued under the FIFO method. Stores and supplies inventories of $258 and $248 at December 31, 2011 and 2010 , respectively, were valued under the average cost method.

Changes in goodwill in 2011 primarily relate to the goodwill associated with the Danisco acquisition (see Note 2). Changes in goodwill in 2010 primarily related to acquisitions in the Agriculture and Safety & Protection segments. In 2011 and 2010 , the company performed impairment tests for goodwill and determined that no goodwill impairments existed.

1. Primarily consists of sales and grower networks, marketing and manufacturing alliances and noncompetition agreements. 2. Microbial cell factories, derived from natural microbes, are used to sustainably produce enzymes, peptides and chemicals using natural metabolic processes. The company recognized the microbial cell factories as an intangible asset upon the acquisition of Danisco. This intangible asset is expected to contribute to cash flows beyond the foreseeable future and there are no legal, regulatory, contractual, or other factors which limit its useful life. 3. Pioneer germplasm is the pool of genetic source material and body of knowledge gained from the development and delivery stage of plant breeding. The company recognized germplasm as an intangible asset upon the acquisition of Pioneer. This intangible asset is expected to contribute to cash flows beyond the foreseeable future and there are no legal, regulatory, contractual, or other factors which limit its useful life. The aggregate pre-tax amortization expense for definite-lived intangible assets was $277, $176 and $252 for 2011, 2010 and 2009, respectively. The estimated aggregate pre-tax amortization expense for 2012, 2013, 2014, 2015 and 2016 is $338, $338, $338, $332 and $269 , respectively, which are primarily reported in cost of goods sold and other operating charges. Estimated aggregate pre-tax amortization expense includes approximately $110 of amortization expense in each of the next five years related to definite-lived intangible assets acquired as part of the Danisco transaction.

— Other loans-various currencies 15 128 Long-term debt payable within one year 410 4 Capital lease obligations 2 1 $ 817 $ 133
The estimated fair value of the company's short-term borrowings, including interest rate financial instruments, based on quoted market prices for the same or similar issues, or on current rates offered to the company for debt of the same remaining maturities, was $830 and $130 at December 31, 2011 and 2010, respectively.
Unused bank credit lines were approximately $4,400 and $2,600 at December 31, 2011 and 2010 , respectively. These lines are available to support short-term liquidity needs and general corporate purposes including letters of credit. Outstanding letters of credit were $354 and $424 at December 31, 2011 and 2010, respectively. These letters of credit support commitments made in the

(Dollars in millions, except per share) ordinary course of business.
The weighted-average interest rate on short-term borrowings outstanding at December 31, 2011 and 2010 was 2.6% and 5.4% , respectively. The decrease in the interest rate reflects the increase in commercial paper in 2011, which had lower interest rates compared to the borrowings in 2010.

1. Average interest rates on medium-term notes at December 31, 2011 and 2010 were 3.7% and 3.4%, respectively. 2. Includes long-term debt due within one year. 3. Interest rate on floating rate notes at December 31, 2011 was 1.0%. 4. At December 31, 2011 and 2010 , the company had outstanding interest rate swap agreements with gross notional amounts of $1,000 . Over the remaining terms of the notes, the company will receive fixed payments equivalent to the underlying debt and pay floating payments based on USD LIBOR (London Interbank Offered Rate) . The fair value of outstanding swaps was an asset of $66 and $40 at December 31, 2011 and 2010, respectively. 5. During 2008, the interest rate swap agreement associated with these notes was terminated. The gain will be amortized over the remaining life of the bond, resulting in an effective yield of 3.85%. In March 2011, the company issued $400 of 1.75% Senior Notes due 2014, $600 of Floating Rate Senior Notes due 2014, $500 of 2.75% Senior Notes due 2016 and $500 of 4.25% Senior Notes due 2021 . The Floating Rate Notes bear interest at three-month USD LIBOR plus 0.42% . The net proceeds of $1,991 from these issuances were used as part of financing the Danisco acquisition. Maturities of long-term borrowings are $1,245, $1,669, $1,465 and $1,594 for the years 2013, 2014, 2015 and 2016, respectively, and $5,740 thereafter.

14. OTHER LIABILITIES

December 31, 2011 2010 Employee benefits: Accrued other long-term benefit costs (Note 17) $ 4,063 $ 3,670 Accrued pension benefit costs (Note 17) 9,186 5,401 Accrued environmental remediation costs 316 317 Miscellaneous 1,943 1,638 $ 15,508 $ 11,026
Miscellaneous includes asset retirement obligations, litigation accruals, tax contingencies, royalty payables and certain obligations related to divested businesses.

15. COMMITMENTS AND CONTINGENT LIABILITIES Guarantees Indemnifications In connection with acquisitions and divestitures, the company has indemnified respective parties against certain liabilities that may arise in connection with these transactions and business activities prior to the completion of the transaction. The term of these indemnifications, which typically pertain to environmental, tax and product liabilities, is generally indefinite. In addition, the company indemnifies its duly elected or appointed directors and officers to the fullest extent permitted by Delaware law, against liabilities incurred as a result of their activities for the company, such as adverse judgments relating to litigation matters. If the indemnified party were to incur a liability or have a liability increase as a result of a successful claim, pursuant to the terms of the indemnification, the company would be required to reimburse the indemnified party. The maximum amount of potential future payments is generally unlimited. The carrying amounts recorded for all indemnifications as of December 31, 2011 and 2010 were $105 and $100 , respectively. Although it is reasonably possible that future payments may exceed amounts accrued, due to the nature of indemnified items, it is not possible to make a reasonable estimate of the maximum potential loss or range of loss. No assets are held as collateral and no specific recourse provisions exist.
In connection with the 2004 sale of the majority of the net assets of Textiles and Interiors, the company indemnified the purchasers, subsidiaries of Koch Industries, Inc. (INVISTA), against certain liabilities primarily related to taxes, legal and environmental matters and other representations and warranties under the Purchase and Sale Agreement. The estimated fair value of the indemnity obligations under the Purchase and Sale Agreement was $70 and was included in the indemnifications balance of $105 at December 31, 2011 . Under the Purchase and Sale Agreement, the company's total indemnification obligation for the majority of the representations and warranties cannot exceed $1,400 . The other indemnities are not subject to this limit. In March 2008, INVISTA filed suit in the Southern District of New York alleging that certain representations and warranties in the Purchase and Sale Agreement were breached and, therefore, that DuPont is obligated to indemnify it. DuPont disagrees with the extent and value of INVISTA's claims. DuPont has not changed its estimate of its total indemnification obligation under the Purchase and Sale Agreement as a result of the lawsuit. A 2012 trial date has been set.
Obligations for Equity Affiliates & Others The company has directly guaranteed various debt obligations under agreements with third parties related to equity affiliates, customers and suppliers. At December 31, 2011, the company had directly guaranteed $563 of such obligations, and $20 relating to guarantees of historical obligations for divested subsidiaries. This represents the maximum potential amount of future (undiscounted) payments that the company could be required to make under the guarantees. The company would be required to perform on these guarantees in the event of default by the guaranteed party.
The company assesses the payment/performance risk by assigning default rates based on the duration of the guarantees. These default rates are assigned based on the external credit rating of the counterparty or through internal credit analysis and historical default history for counterparties that do not have published credit ratings. For counterparties without an external rating or available credit history, a cumulative average default rate is used.

F-22Table of Contents E. I. du Pont de Nemours and Company Notes to the Consolidated Financial Statements (continued)

(Dollars in millions, except per share) In certain cases, the company has recourse to assets held as collateral, as well as personal guarantees from customers and suppliers. Assuming liquidation, these assets are estimated to cover approximately 50 percent of the $362 of guaranteed obligations of customers and suppliers. Set forth below are the company's guaranteed obligations at December 31, 2011 :

Short-Term Long-Term Total Obligations for customers and suppliers 1 : Bank borrowings (terms up to 5 years) $ 278 $ 83 $ 361 Leases on equipment and facilities (terms up to 3 years)

— 1 1
Obligations for equity affiliates 2 : Bank borrowings (terms less than 2 years) 199 2 201 Total obligations for customers, suppliers, and equity affiliates 477 86 563 Obligations for divested subsidiaries: Conoco (terms up to 15 years) 3

— 16 16 Other (terms up to 6 years)

— 4 4 Total $ 477 $ 106 $ 583

1. Existing guarantees for customers and suppliers arose as part of contractual agreements. 2. Existing guarantees for equity affiliates arose for liquidity needs in normal operations. 3. The company has guaranteed certain obligations and liabilities related to a divested subsidiary, Conoco, which has indemnified the company for any liabilities the company may incur pursuant to these guarantees. Operating Leases The company uses various leased facilities and equipment in its operations. The terms for these leased assets vary depending on the lease agreement.
Future minimum lease payments (including residual value guarantee amounts) under non-cancelable operating leases are $293, $251, $194, $151 and $128 for the years 2012, 2013, 2014, 2015 and 2016, respectively, and $230 for subsequent years and are not reduced by non-cancelable minimum sublease rentals due in the future in the amount of $6. Net rental expense under operating leases was $308, $268 and $302 in 2011, 2010 and 2009, respectively.
Asset Retirement Obligations The company has recorded asset retirement obligations primarily associated with closure, reclamation and removal costs for mining operations related to the production of titanium dioxide in Performance Chemicals. The company's asset retirement obligation liabilities were $59 at December 31, 2011 and 2010 .
Imprelis ® The company has received claims and been served with multiple lawsuits seeking class action status alleging that the use of Imprelis ® herbicide caused damage to certain trees. In August 2011, the company suspended sales of Imprelis ® . In September 2011, the company began a process to fairly resolve claims associated with the use of Imprelis ® . The deadline for property owners to file claims was extended to February 1, 2012 as long as the company received notice of the intent to file by November 30, 2011. The company has established review processes to verify and evaluate damage claims, and based on current information, the company recorded a charge of $175 in cost of goods sold and other operating charges in 2011 to resolve these claims. Additional charges could be incurred, but can be reasonably estimated only after claims are made known and the company's review processes are completed. DuPont intends to seek recovery from its insurance carriers for costs associated with this matter in excess of $100

. Litigation The company is subject to various legal proceedings arising out of the normal course of its business including product liability, intellectual property,
comm ercial, environmental and antitrust lawsuits. It is not possible to predict the outcome of these various proceedings. Except as otherwise noted, management does not anticipate their resolution will have a materially adverse effect on the company's consolidated financial position or liquidity. However, the ultimate liabilities could be significant to results of operations in the period recognized.

PFOA DuPont uses PFOA (collectively, perfluorooctanoic acids and its salts, including the ammonium salt), as a processing aid to manufacture fluoropolymer resins and dispersions at various sites around the world including its Washington Works plant in West Virginia. At December 31, 2011 , DuPont has accruals of $16 related to the PFOA matters discussed below.
The accrual includes charges related to DuPont's obligations under agreements with the U.S. Environmental Protection Agency and voluntary commitments to the New Jersey Department of Environmental Protection. These obligations include surveying, sampling and testing drinking water in and around the company's Washington Works site and offer treatment or an alternative supply of drinking water if tests indicate the presence of PFOA in drinking water at or greater than the national Provisional Health Advisory.
Drinking Water Actions In August 2001, a class action, captioned Leach v DuPont, was filed in West Virginia state court alleging that residents living near the Washington Works facility had suffered, or may suffer, deleterious health effects from exposure to PFOA in drinking water.
DuPont and attorneys for the class reached a settlement in 2004 that binds about 80,000 residents. In 2005, DuPont paid the plaintiffs’ attorneys’ fees and expenses of $23 and made a payment of $70 , which class counsel designated to fund a community health project. The company is also funding a series of health studies by an independent science panel of experts (the “C8 Science Panel”) in the communities exposed to PFOA to evaluate available scientific evidence on whether any probable link exists between exposure to PFOA and human disease. The company expects the C8 Science Panel to complete these health studies through July 2012 at a total estimated cost of $33.
In December 2011, the C8 Science Panel announced that on the basis of epidemiologic and other scientific data available to it, the panel has concluded that there is a probable link, as defined in the settlement agreement, between exposure to PFOA and pregnancy-induced hypertension, which includes preeclampsia. A panel of medical experts will determine an appropriate medical monitoring protocol, if any, as a result of this finding. If a medical monitoring protocol is defined, DuPont is required to fund a medical monitoring program to pay for such medical testing. Plaintiffs may pursue personal injury claims against DuPont only for those human disease(s) for which the C8 Science Panel determines a probable link exists once the C8 Science Panel completes its work. In January 2012, the company put $1 in an escrow account as required by the settlement agreement. The company will reassess its liability based on the medical monitoring panel's determination since costs are not reasonably estimable until a medical monitoring protocol, if any, is identified. The company will continue to reassess its liability based on the C8 Science Panel's future probable link findings, if any, and associated medical monitoring protocols, if any. Under the settlement agreement, the company's total obligation to pay for medical monitoring cannot exceed $235 . In addition, the company must continue to provide state-of-the-art water treatment systems designed to reduce the level of PFOA in water to six area water districts, including the Little Hocking Water Association (LHWA), and private well users.
During the fourth quarter 2011, the company reached final resolution of three actions brought by or on behalf of water district customers. The West Virginia action was resolved in DuPont's favor when the U.S. Supreme Court refused in October to hear plaintiffs' appeal. The two consolidated New Jersey actions were finally resolved with the settlement payment of $8.3 in October 2011. The pending Ohio action was brought by the LHWA and is currently in discovery. In addition to general claims of PFOA contamination of drinking water, the action claims “imminent and substantial endangerment to health and or the environment” under the Resource Conservation and Recovery Act (RCRA). DuPont denies these claims and is defending itself vigorously.
While DuPont believes that it is reasonably possible that it could incur losses related to PFOA matters in addition to those matters discussed above for which it has established accruals, a range of such losses, if any, cannot be reasonably estimated at this time.

Environmental The company is also subject to contingencies pursuant to environmental laws and regulations that in the future may require the company to take further action to correct the effects on the environment of prior disposal practices or releases of chemical or petroleum substances by the company or other parties. The company accrues for environmental remediation activities consistent with the policy set forth in Note 1. Much of this liability results from the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA, often referred to as Superfund), RCRA and similar state and global laws. These laws require the company to undertake certain investigative, remediation and restoration activities at sites where the company conducts or once conducted operations or at sites where company-generated waste was disposed. The accrual also includes estimated costs related to a number of sites identified by the company for which it is probable that environmental remediation will be required, but which are not currently the subject of enforcement activities.

Remediation activities vary substantially in duration and cost from site to site. These activities, and their associated costs, depend on the mix of unique site characteristics, evolving remediation technologies, diverse regulatory agencies and enforcement policies, as well as the presence or absence of potentially responsible parties. At December 31, 2011, the Consolidated Balance Sheet included a liability of $416 , relating to these matters and, in management's opinion, is appropriate based on existing facts and circumstances. The average time frame, over which the accrued or presently unrecognized amounts may be paid, based on past history, is estimated to be 15-20 years. Considerable uncertainty exists with respect to these costs and, under adverse changes in circumstances, potential liability may range up to three times the amount accrued as of December 31, 2011.

Other The company has various purchase commitments incident to the ordinary conduct of business. In the aggregate, such commitments are not at prices in excess of current market.

16. STOCKHOLDERS' EQUITY The company's Board of Directors authorized a $2,000 share buyback plan in June 2001. During 2011 , the company purchased and retired 13.8 million shares at a total cost of

$672 under this plan. During 2010 , the company purchased and retired 5.4 million shares at a total cost of $250. During 2009 , there were no purchases of stock under this plan. As of December 31, 2011, the company has purchased 39.7 million shares at a total cost of $1,884 . In April 2011, the company's Board of Directors authorized a $2,000 share buyback plan. This plan will not commence until the plan authorized in June 2001 is completed. There is no expiration date on the current authorizations.
Common stock held in treasury is recorded at cost. When retired, the excess of the cost of treasury stock over its par value is allocated between reinvested earnings and additional paid-in capital.

17. LONG-TERM EMPLOYEE BENEFITS The company offers various long-term benefits to its employees. Where permitted by applicable law, the company reserves the right to change, modify or discontinue the plans.

Defined Benefit Pensions The company has both funded and unfunded noncontributory defined benefit pension plans covering a majority of the U.S. employees hired prior to January 1, 2007. The benefits under these plans are based primarily on years of service and employees' pay near retirement. The company's funding policy is consistent with the funding requirements of federal laws and regulations. Pension coverage for employees of the company's non-U.S. consolidated subsidiaries is provided, to the extent deemed appropriate, through separate plans. Obligations under such plans are funded by depositing funds with trustees, covered by insurance contracts, or remain unfunded.
Other Long-term Employee Benefits The parent company and certain subsidiaries provide medical, dental and life insurance benefits to pensioners and survivors, and disability and life insurance protection to employees. The associated plans for retiree benefits are unfunded and the cost of the approved claims is paid from company funds. Essentially all of the cost and liabilities for these retiree benefit plans are attributable to the U.S. parent company plans. The retiree medical plan is contributory with pensioners and survivors' contributions adjusted annually to achieve a 50/50 target sharing of cost increases between the company and pensioners and survivors. In addition, limits are applied to the company's portion of the retiree medical cost coverage. The majority of U.S. employees hired on or after January 1, 2007 are not eligible to participate in the post retirement medical, dental and life insurance plans.
Employee life insurance and disability benefit plans are insured in many countries. However, primarily in the U.S., such plans are generally self-insured or are fully experience-rated. Obligations and expenses for self-insured and fully experience-rated plans are reflected in the figures below.

1. Change is primarily due to an amendment in 2010 to the company's U.S. parent company retiree medical plan to take advantage of a 50 percent discount from brand name drug manufacturers in the "coverage gap" portion of the Medicare Part D plan. The plan amendment has no effect on current or future retirees' coverage. 2. Includes pension plans maintained around the world where funding is not customary.

For determining U.S. plans' net periodic benefit costs, the discount rate, expected return on plan assets and the rate of compensation increase were 5.50 percent , 9.00 percent and 4.50 percent for 2011 , 6.00 percent , 9.00 percent and 4.50 percent for 2010 and 6.25 percent , 9.00 percent and 4.50 percent for 2009

. The company utilizes published long-term high quality corporate bond indices to determine the discount rate at measurement date. Where commonly available, the company considers indices of various durations to reflect the timing of future benefit payments.
The long-term rate of return on assets in the U.S. was selected from within the reasonable range of rates determined by historical real returns (net of inflation) for the asset classes covered by the investment policy, expected performance, and projections of inflation over the long-term period during which benefits are payable to plan participants. Consistent with prior years, the long-term rate of return on plan assets in the U.S. reflects the asset allocation of the plan and the effect of the company's active management of the plans' assets. For non-U.S. plans, assumptions reflect economic assumptions applicable to each country.

Plan Assets All pension plan assets in the U.S. are invested through a single master trust fund. The strategic asset allocation for this trust fund is selected by management, reflecting the results of comprehensive asset liability modeling. The general principles guiding U.S. pension asset investment policies are those embodied in the Employee Retirement Income Security Act of 1974 (ERISA). These principles include discharging the company's investment responsibilities for the exclusive benefit of plan participants and in accordance with the "prudent expert" standard and other ERISA rules and regulations. The company establishes strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes with the aim of achieving a prudent balance between return and risk. Strategic asset allocations in other countries are selected in accordance with the laws and practices of those countries. Where appropriate, asset liability studies are utilized in this process. U.S. plan assets and a portion of non-U.S. plan assets are managed by investment professionals employed by the company. The remaining assets are managed by professional investment firms unrelated to the company. The company's pension investment professionals have discretion to manage the assets within established asset allocation ranges approved by senior management of the company. Additionally, pension trust funds are permitted to enter into certain contractual arrangements generally described as "derivatives." Derivatives are primarily used to reduce specific market risks, hedge currency and adjust portfolio duration and asset allocation in a cost-effective manner.
The weighted-average target allocation for plan assets of the company's U.S. and non-U.S. pension plan is summarized as follows:
Target allocation for plan assets at December 31, 2011 2010 U.S. equity securities 27 % 30 % Non-U.S. equity securities 20 22 Fixed income securities 29 29 Hedge funds 2

— Private market securities 14 12 Real estate 8 7 Total 100 % 100 %
Equity securities include varying market capitalization levels. U.S. equity investments are primarily large-cap companies. Fixed income investments include corporate-issued, government-issued and asset-backed securities. Corporate debt investments include a range of credit risk and industry diversification. U.S. fixed income investments are weighted heavier than non-U.S fixed income securities. Other investments include hedge funds, real estate and private market securities such as interests in private equity and venture capital partnerships.
Fair value calculations may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

Defined Contribution Plan The company sponsors several defined contribution plans, which cover substantially all U.S. employees. The most significant is the U.S. parent company's Retirement Savings Plan (the Plan), which reflects the 2009 merger of the Retirement Savings Plan and the Savings and Investment Plan. This Plan includes a non-leveraged Employee Stock Ownership Plan (ESOP). Employees are not required to participate in the ESOP and those who do are free to diversify out of the ESOP. The purpose of the Plan is to provide retirement savings benefits for employees and to provide employees an opportunity to become stockholders of the company. The Plan is a tax qualified contributory profit sharing plan, with cash or deferred arrangement and any eligible employee of the company may participate. The company contributes 100 percent of the first 6 percent of the employee's contribution election and also contributes 3 percent of each eligible employee's eligible compensation regardless of the employee's contribution. The company's contributions to the U.S. parent company's defined contribution plans were $210, $195 and $191 for the years ended December 31, 2011, 2010 and 2009 , respectively. The company's matching contributions vest immediately upon contribution. The 3 percent nonmatching company contribution vests for employees with at least three years of service. In addition, the company made contributions to other defined contribution plans of $84, $59 and $54 for the years ended December 31, 2011, 2010 and

F-33Table of Contents E. I. du Pont de Nemours and Company Notes to the Consolidated Financial Statements (continued)

(Dollars in millions, except per share) 2009 , respectively. The company expects to contribute about $335 to its defined contribution plans in 2012 .

18. COMPENSATION PLANS The total stock-based compensation cost included in the Consolidated Income Statements was $113, $108 and $115 for 2011, 2010 and 2009 , respectively. The income tax benefits related to stock-based compensation arrangements were $37, $36 and $38 for 2011, 2010 and 2009, respectively.
In April 2011, the shareholders approved amendments to the DuPont Equity and Incentive Plan (EIP). The EIP provides for equity-based and cash incentive awards to certain employees, directors, and consultants. Under the amended EIP, the maximum number of shares reserved for the grant or settlement of awards is 110 million shares, provided that each share in excess of 30 million that is issued with respect to any award that is not an option or stock appreciation right will be counted against the 110 million share limit as four and one-half shares. At December 31, 2011 , approximately 67 million shares were authorized for future grants under the company's EIP. The company satisfies stock option exercises and vesting of time-vested restricted stock units (RSUs) and performance-based restricted stock units (PSUs) with newly issued shares of DuPont common stock.
The company's Compensation Committee determines the long-term incentive mix, including stock options, RSUs and PSUs and may authorize new grants annually.
Stock Options The exercise price of shares subject to option is equal to the market price of the company's stock on the date of grant. Options granted prior to 2004 expire 10 years from date of grant; options granted between 2004 and 2008 serially vested over a three-year period and carry a six -year option term. Stock option awards granted between 2009 and 2011 expire seven years after the grant date. The plan allows retirement eligible employees to retain any granted awards upon retirement provided the employee has rendered at least six months of service following grant date.
For purposes of determining the fair value of stock options awards, the company uses the Black-Scholes option pricing model and the assumptions set forth in the table below. The weighted-average grant-date fair value of options granted in 2011, 2010 and 2009 was $12.32, $6.44 and $2.68, respectively.

2011 2010 2009 Dividend yield 3.2 % 4.9 % 7.0 % Volatility 33.26 % 32.44 % 27.61 % Risk-free interest rate 2.3 % 2.6 % 2.5 % Expected life (years) 5.3 5.3 5.3
The company determines the dividend yield by dividing the current annual dividend on the company's stock by the option exercise price. A historical daily measurement of volatility is determined based on the expected life of the option granted. The risk-free interest rate is determined by reference to the yield on an outstanding U.S. Treasury note with a term equal to the expected life of the option granted. Expected life is determined by reference to the company's historical experience.

F-34Table of Contents E. I. du Pont de Nemours and Company Notes to the Consolidated Financial Statements (continued)

(Dollars in millions, except per share) Stock option awards as of December 31, 2011, and changes during the year then ended were as follows:

Number of Shares (in thousands) Weighted Average Exercise Price (per share) Weighted Average Remaining Contractual Term (years) Aggregate Intrinsic Value (in thousands)
Outstanding, December 31, 2010 62,887 $ 38.83 Granted 3,739 $ 51.85 Exercised (20,677 ) $ 41.85 Forfeited (88 ) $ 35.14 Cancelled (815 ) $ 46.29 Outstanding, December 31, 2011 1 45,046 $ 38.40 2.68 $ 381,386 Exercisable, December 31, 2011 32,020 $ 39.88 1.75 $ 214,349

1. Includes 5.4 million options outstanding from the 2002 Corporate Sharing Program grants of 200 shares to all eligible employees at an option price of $44.50

. These options expired in January 2012. The aggregate intrinsic values in the table above represent the total pre-tax intrinsic value (the difference between the company's closing stock price on the last trading day of 2011 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their in-the-money options at year end. The amount changes based on the fair market value of the company's stock. Total intrinsic value of options exercised for 2011, 2010 and 2009 were $216 , $109 and $0 , respectively. In 2011, the company realized a tax benefit of $67 from options exercised.
As of December 31, 2011 , $16 of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of 1.74 years.

RSUs and PSUs The company issues RSUs that serially vest over a three-year period and, upon vesting, convert one-for-one to DuPont common stock. A retirement eligible employee retains any granted awards upon retirement provided the employee has rendered at least six months of service following the grant date. Additional RSUs are also granted periodically to key senior management employees. These RSUs generally vest over periods ranging from two to five years. The fair value of all stock-settled RSUs is based upon the market price of the underlying common stock as of the grant date.
The company also grants PSUs to senior leadership. In 2011 , there were 215,531 PSUs granted. Vesting for PSUs granted in 2009, 2010 and 2011 is equally based upon corporate revenue growth relative to peer companies and total shareholder return (TSR) relative to peer companies. Performance and payouts are determined independently for each metric. The actual award, delivered as DuPont common stock, can range from zero percent to 200 percent of the original grant. The grant-date fair value of the PSUs granted in 2011, subject to the TSR metric, was $72.25 , estimated using a Monte Carlo simulation. The grant-date fair value of the PSUs, subject to the revenue metric, was based upon the market price of the underlying common stock as of the grant date.
Non-vested awards of RSUs and PSUs as of December 31, 2011 and 2010 are shown below. The weighted-average grant-date fair value of RSUs and PSUs granted during 2011 , 2010 and 2009 was $53.19 , $34.60 and $23.72 , respectively.

Number of Shares (in thousands) Weighted Average Grant Date Fair Value (per share) Nonvested, December 31, 2010 4,118 $ 32.27 Granted 1,545 $ 53.19 Vested (1,998 ) $ 36.92 Forfeited (84 ) $ 37.53 Nonvested, December 31, 2011 3,581 $ 38.58
As of December 31, 2011 , there was $38 unrecognized stock-based compensation expense related to nonvested awards. That cost

F-35Table of Contents E. I. du Pont de Nemours and Company Notes to the Consolidated Financial Statements (continued)

(Dollars in millions, except per share) is expected to be recognized over a weighted-average period of 1.75 years. The total fair value of stock units vested during 2011, 2010 and 2009 was $74, $64 and $74, respectively.

Other Cash-based Awards Cash awards under the EIP plan may be granted to employees who have contributed most to the company's success, with consideration being given to the ability to succeed to more important managerial responsibility. Such awards were $85, $112 and $66 for 2011, 2010 and 2009, respectively. The amounts of the awards are dependent on company earnings and are subject to maximum limits as defined under the governing plans.
In addition, the company has other variable compensation plans under which cash awards may be granted. These plans include Pioneer's Annual Reward Program and the company's regional and local variable compensation plans. Such awards were $386, $422 and $288 for 2011, 2010 and 2009, respectively.

19. DERIVATIVES AND OTHER HEDGING INSTRUMENTS Objectives and Strategies for Holding Derivative Instruments In the ordinary course of business, the company enters into contractual arrangements (derivatives) to reduce its exposure to foreign currency, interest rate and commodity price risks. The company has established a variety of derivative programs to be utilized for financial risk management. These programs reflect varying levels of exposure coverage and time horizons based on an assessment of risk.
Derivative programs have procedures and controls and are approved by the Corporate Financial Risk Management Committee, consistent with the company's financial risk management policies and guidelines. Derivative instruments used are forwards, options, futures and swaps. The company has not designated any nonderivatives as hedging instruments.
The company's financial risk management procedures also address counterparty credit approval, limits and routine exposure monitoring and reporting. The counterparties to these contractual arrangements are major financial institutions and major commodity exchanges. The company is exposed to credit loss in the event of nonperformance by these counterparties. The company anticipates performance by counterparties to these contracts and therefore no material loss is expected. Market and counterparty credit risks associated with these instruments are regularly reported to management.
The notional amounts of the company's derivative instruments were as follows:

December 31, 2011 2010 Derivatives designated as hedging instruments: Interest rate swaps $ 1,000 $ 1,000 Foreign currency contracts 2,032 1,220 Commodity contracts 553 448 Derivatives not designated as hedging instruments: Foreign currency contracts 6,444 7,449 Commodity contracts 437 310
Foreign Currency Risk The company's objective in managing exposure to foreign currency fluctuations is to reduce earnings and cash flow volatility associated with foreign currency rate changes. Accordingly, the company enters into various contracts that change in value as foreign exchange rates change to protect the value of its existing foreign currency-denominated assets, liabilities, commitments and cash flows.
The company routinely uses forward exchange contracts to offset its net exposures, by currency, related to the foreign currency-denominated monetary assets and liabilities of its operations. The primary business objective of this hedging program is to maintain an approximately balanced position in foreign currencies so that exchange gains and losses resulting from exchange rate changes, net of related tax effects, are minimized. The company also uses foreign currency exchange contracts to offset a portion of the company's exposure to certain foreign currency-denominated revenues so that gains and losses on these contracts offset changes in the USD value of the related foreign currency-denominated revenues. The objective of the hedge program is to reduce earnings and cash flow volatility related to changes in foreign currency exchange rates.

(Dollars in millions, except per share)

Interest Rate Risk The company uses interest rate swaps to manage the interest rate mix of the total debt portfolio and related overall cost of borrowing. Interest rate swaps involve the exchange of fixed for floating rate interest payments to effectively convert fixed rate debt into floating rate debt based on USD LIBOR. Interest rate swaps allow the company to achieve a target range of floating rate debt.
Commodity Price Risk Commodity price risk management programs serve to reduce exposure to price fluctuations on purchases of inventory such as natural gas, copper, corn, soybeans and soybean meal. The company enters into over-the-counter and exchange-traded derivative commodity instruments to hedge the commodity price risk associated with energy feedstock and agricultural commodity exposures.
Fair Value Hedges Interest Rate Swaps At December 31, 2011 , the company maintained a number of interest rate swaps, which were implemented at the time debt instruments were issued, to manage the interest rate mix of the total debt portfolio and related overall cost of borrowing. These swaps involve the exchange of fixed for floating rate interest payments to effectively convert fixed rate debt into floating rate debt based on USD LIBOR, allowing the company to achieve a target range of floating rate debt. All interest rate swaps qualify for the shortcut method of hedge accounting, thus there is no ineffectiveness related to these hedges.
Cash Flow Hedges Foreign Currency Contracts The company's objective in managing exposure to foreign currency fluctuations is to reduce earnings and cash flow volatility associated with foreign currency rate changes. Accordingly, the company uses foreign currency exchange instruments such as forwards and options to offset a portion of the company's exposure to certain foreign currency-denominated revenues so that gains and losses on these contracts offset changes in the USD value of the related foreign currency-denominated revenues.
Commodity Contracts Commodity price risk management programs serve to reduce exposure to price fluctuations on purchases of inventory such as natural gas, copper, corn, soybeans and soybean meal. The company enters into over-the-counter and exchange-traded derivative commodity instruments, including options, futures and swaps, to hedge the commodity price risk associated with these exposures.
Treasury Rate Contracts During 2010 and 2009 , the company entered into treasury rate contracts to hedge the company's exposure to treasury rates on a portion of planned bond issuances. The contracts were terminated at the time the bonds were issued prior to year end.
While each risk management program has a different time maturity period, most programs currently do not extend beyond the next two-year period. Cash flow hedge results are reclassified into earnings during the same period in which the related exposure impacts earnings. Reclassifications are made sooner if it appears that a forecasted transaction will not materialize. The following table summarizes the effect of cash flow hedges on accumulated other comprehensive income (loss) for the years ended December 31, 2011 and 2010 :

2011 2010 Pre-tax Tax After-tax Pre-tax Tax After-tax Beginning balance $ (47 ) $ 16 $ (31 ) $ (101 ) $ 36 $ (65 ) Additions and revaluations of derivatives designated as cash flow hedges 17 (5 ) 12 (36 ) 14 (22 )
Clearance of hedge results to earnings 96 (36 ) 60 90 (34 ) 56 Ending balance $ 66 $ (25 ) $ 41 $ (47 ) $ 16 $ (31 )
During the next 12 months, the pre-tax, tax and after-tax amounts expected to be reclassified from accumulated other comprehensive income (loss) into earnings is $73 , $(28) and $45 , respectively.

F-37Table of Contents E. I. du Pont de Nemours and Company Notes to the Consolidated Financial Statements (continued)

(Dollars in millions, except per share) Derivatives not Designated in Hedging Relationships Foreign Currency Contracts The company routinely uses forward exchange contracts to reduce its net exposure, by currency, related to foreign currency-denominated monetary assets and liabilities of its operations so that exchange gains and losses resulting from exchange rate changes are minimized. The netting of such exposures precludes the use of hedge accounting; however, the required revaluation of the forward contracts and the associated foreign currency-denominated monetary assets and liabilities intends to achieve a minimal earnings impact, after taxes. Additionally, in 2011 , the company entered into cross-currency swaps to hedge foreign currency fluctuations on long-term intercompany loans associated with the acquisition of Danisco businesses.
Commodity Contracts The company also utilizes options, futures and swaps that are not designated as hedging instruments to reduce exposure to commodity price fluctuations on purchases of inventory such as corn, soybeans and soybean meal and electricity.

for a reduced monthly pension payable under Section IV (the Early or Optional Retirement provisions) of the Company's Pension and Retirement Plan.

Such calendar years shall be selected beginning with the calendar year in which average pay per month was the highest and taking in turn calendar years of successively lower average pay per month. A fraction of total pay for a calendar year shall be by multiplying average pay per month for that year by the number of months needed to yield an aggregate amount of service equivalent to three full years. Only pay for the 120 calendar months up to and including the calendar month in which the employee retires under the Company's Pens1on Plan will be taken into account in computing Average Total Monthly Pay.

The value of an award under the Variable Compensation Plan, or the Incentive Compensation Plan will be the total award value approved by the Compensation and Benefits Committee. The value of an award under the former Dividend Unit Plan will be the value used by the Compensation and Benefits Committee in determining the number of dividend units awarded to an employee. (d) Where a retired employee is granted an award under the Variable Compensation Plan, the Incentive Compensation Plan or the former Dividend Unit Plan for the calendar year in which his retirement is effective, his Average Total Monthly Pay will be recomputed and, if applicable, his monthly supplemental retirement income will be increased beginning the month following that in which such award is granted.
3. The term "Service" means the length, in years and fractions of a year, of an employee's period of "continuous

service" as determined under the Company's Continuity of Service Rules for computing the amount of a pension and, to the extend prescribed in such Rules, recognition will be given for service which the employee has rendered to an affiliated company or to a company whose assets have been acquired in whole or in part, by the Company.

## I. du Pont de Nemours and Company, any wholly owned subsidiary or part

thereof and any partnership or joint venture in which E. 

## I. du Pont de Nemours and Company is joined which adopts this Plan with the approval of the Company, or such person or persons as the Company may designate. B.

2. All expenses and costs in connection with the operation of this Plan shall be borne by the Company out of its

general assets.
F. Amendment The Company reserves the right to change this Plan in its discretion by action of the Compensation and Benefits Committee or its delegate, or to discontinue this Plan in its discretion by action of the Board of Directors, provided that the right to an amount payable to a person for any calendar year, calculated in accordance with the terms of this Plan at the time of benefit commencement, will not be reduced or eliminated by an amendment or termination of this Plan.

STOCK PERFORMANCE PLAN

I. PURPOSES
The purposes of this Stock Performance Plan (the "Plan") are: (a) to provide greater incentive for employees who are or will be primarily responsible for the growth and success of the business to exert their best efforts on behalf of E. I. du Pont de Nemours and Company ("the Company"); and (b) to further the identity of interests of such employees with those of the Company's stockholders generally by encouraging them to acquire stock ownership in the Company.

II. FORM OF GRANTS

1 Grants under this Plan may be made in the form of stock options, stock options accompanied by stock appreciation rights, restricted shares or units ("restricted stock") or a combination of any of these forms and may be made in replacement of or as alternatives to salary or grants under any other plan or program of a plan company.

2 Stock options to purchase shares of the Company's common stock granted under this Plan may be either incentive, performance or other stock options qualified under the Internal Revenue Code as in effect from time to time ("qualified stock options") or stock options that are not qualified under the Internal Revenue Code ("nonqualified stock options"), or a combination of qualified and nonqualified stock options.

3 Stock appreciation rights may be granted by the Company under this Plan upon such terms and conditions as the Compensation Committee may determine. Such rights may be granted only when they accompany the concurrent grant of stock options. Each stock appreciation right shall give the grantee the right to receive a payment equal to the excess of the fair market value of a share of the Company's common stock on the date when such right is exercised over the option price provided for in the accompanying stock option. Such rights may be exercised only if the grantee exercises the accompanying stock option by purchasing one share of the Company's common stock for each stock appreciation right exercised. The number of shares subject to exercise under an accompanying stock option shall be automatically reduced by one share for each stock appreciation right exercised.

4 Restricted stock granted under this Plan shall be subject to restriction, such as forfeiture and a minimum vesting period. A grantee of restricted shares shall generally have all incidents of ownership in the restricted shares, including the right to dividends and to vote (unless otherwise restricted). Restricted shares may be evidenced by book-entry registration, a stock certificate registered in the grantee's name but held in the Company's custody or issuance of an appropriate legended stock certificate, as determined by the Compensation Committee.III. LIMITATIONS ON GRANTS

1 The aggregate number of shares of the Company's stock which may be made subject to stock options granted under this Plan shall not exceed 72,000,000, or 5% of such number for any optionee, during any five consecutive years, of which only 12,000,000 shares may be subject to restricted stock grants. The number of stock appreciation rights which may be granted to any optionee under this Plan shall not exceed 50% of the number of shares made subject to an accompanying stock option.

2 If any stock option or restricted stock (without benefit of dividends) granted under this Plan shall terminate or expire for any reason without having been exercised or vested in full, the shares not acquired under such grant shall become available again for further grants under this Plan; provided also, that shares withheld by or tendered to the Company as payment fo exercise price or other consideration or satisfaction of withholding taxes shall become available again for further grants to employees who are not executive officers; provided, however, that the shares which become so available for further grants shall not include any shares as to which a stock option has been reduced by reason of receiving payments under accompanying stock appreciation rights. The limitations set forth above shall be subject to adjustment as provided in Article XII hereof.

IV. ADMINISTRATION

1 Except as otherwise specifically provided, the Plan shall be administered by the Compensation Committee of the Company's Board of Directors. The Compensation Committee shall be elected pursuant to the Bylaws of the Company, and the members thereof shall be ineligible for grants while serving on said Committee.

2 The Compensation Committee is authorized, subject to the provisions of the Plan, from time to time to establish such rules and regulations as it deems appropriate for the proper administration of the Plan, and to make such determinations and take such steps in connection therewith as it deems necessary or advisable.

3 The Compensation Committee shall, subject to the provisions of the Plan, determine the time or times when stock options will be granted, which employees, if any, shall be granted stock options, the types of stock options to be granted, whether they shall be granted singly or in combination, when they shall be exercisable, the number of shares to be covered by each stock option or options, and the terms and conditions of such stock options; which employees, if any, shall also be granted accompanying stock appreciation rights, the number of stock appreciation rights which shall be granted to each of them, and the terms and conditions of such rights; and the time or times when restricted stock will be granted, which employees, if any, shall be granted restricted stock, the number of restricted shares to be granted, the restrictions or conditions on the right to transfer or dispose of such shares, and the terms and conditions of such restricted stock, including the number, amount, and timing of vesting increments.

4 The decision of the Compensation Committee with respect to any questions arising as to interpretation of this Plan, including the severability of any and all of the provisions thereof, shall be final, conclusive and binding.

5 The Company's Board of Directors may elect a Special Stock Performance Committee pursuant to the Bylaws of the Company which shall have and may exercise all the rights, powers and duties of the Compensation Committee specified in this Plan for purposes of making grants for significant achievements by employees who are not directors or executive officers of the Company. The Special Stock Performance Committee may also be authorized by the Compensation Committee to assume certain administrative responsibilities under this Plan.V. ELIGIBILITY FOR GRANTS

1 Grants under this Plan may be made to employees (including those who are directors or executive officers of the Company) as determined by the Compensation Committee (or Board of Directors, if the grantee is a director of the Company). In determining those employees to whom grants are to be made, the Compensation Committee (or Board of Directors, if the grantee is a director of the Company) may take into consideration present and potential contributions to the Company's success by such employees, and any other factors which the Compensation Committee (or Board of Directors, if the grantee is a director of the Company) may deem relevant in connection with accomplishing the purposes of the Plan.

2 The term "employee” may include an employee of a corporation or other business entity in which the Company shall directly or indirectly own fifty percent or more of the outstanding voting stock or other ownership interest, but shall exclude any director who is not also an officer or a full-time employee of a plan company. The term "plan company" as used in this Plan shall mean a business entity whose employees are eligible for grants under this Plan. The term "grantee" as used in this Plan means an employee to whom a grant has been made under this Plan or, where appropriate, his or her successor in interest upon death.

VI. RECOMMENDATIONS AND GRANTS

1 Recommendations for grants to members of the Board of Directors shall be made by the Compensation Committee. Recommendations for grants to employees who are not members of the Board of Directors shall be made to the Compensation Committee by the Office of the Chief Executive.

2 Any grant to a director shall be made in the sole discretion of the Board of Directors, a majority of whose members taking final action on any such grant shall be ineligible for grants under Article V. Any grant to an employee who is not a member of the Board of Directors shall be made by the Compensation Committee which shall take final action on any such grant.

3 Grants may be made at any time under this Plan and in any of the forms or combinations thereof provided in Article II hereof. A grantee may receive and may hold more than one grant under this Plan.

4 The date on which a grant shall be deemed to have been made under this Plan shall be the date of the Compensation Committee (or Board of Directors, if the grantee is a director) authorization of the grant or such later date as may be determined by the Compensation Committee (or Board of Directors, if the grantee is a director) at the time the grant is authorized. Each grantee shall be advised in writing by the Company of a grant and the terms and conditions thereof, which terms and conditions, as the Compensation Committee from time to time shall determine, shall not be inconsistent with the provisions of this Plan.VII. OPTION PRICE

The price per share of the Company's common stock which may be purchased upon exercise of a stock option granted under this Plan shall be determined by the Compensation Committee, but shall in no event be less than the fair market value of such share on the date the stock option is granted, and in no event less than the par value thereof. The price so determined also shall be applicable to any accompanying stock appreciation right. For purposes of this Plan, fair market value shall be the closing price of the Company's common stock as reported on the "NYSE-Composite Transactions Tape" on the date of grant of a stock option or the date of exercise of a stock option or stock appreciation right, or if no sales of such stock were reported on said Tape on such date, the closing price of such stock on the next preceding day on which sales were reported on said Tape. Such price shall be subject to adjustment as provided in Article XII hereof.

VIII. OPTION TERM
The term of each stock option and each stock appreciation right granted under this Plan shall be for such period as the Compensation Committee shall determine, but not for more than ten years from date of grant.IX. EXERCISE OF OPTIONS

1 Subject to the provisions of this Plan, each stock option and each stock appreciation right granted hereunder shall be exercisable on such date or dates and during such period and for such number of shares or stock appreciation rights as the Compensation Committee may determine. However, in no event shall a stock option or stock appreciation right be exercisable prior to six months from date of grant. The Compensation Committee may fix from time to time a minimum number of shares which must be purchased at the time a stock option is exercised.

2 A grantee electing to exercise a stock option shall at the time of exercise pay the Company the full purchase price of the shares he or she has elected to purchase. Payment of the purchase price shall be made in cash, the Company's common stock (valued at fair market value on the date of exercise), or a combination thereof, as the Compensation Committee may determine from time to time. A grantee electing to exercise a stock appreciation right granted under this Plan shall so notify the Company at the same time he or she elects to exercise an accompanying stock option. Payment by the Company for such stock appreciation right may be in cash, common stock (valued at fair market value on date of exercise), or a combination thereof, as the Compensation Committee may determine from time to time, but no fractional share of common stock shall be delivered. With respect to shares of the Company's common stock to be delivered upon exercise of a stock option or a stock appreciation right, the Compensation Committee shall periodically determine whether, and to what extent, such stock shall be in the form of new common stock issued for such purposes, or common stock acquired by the Company.

3 Notwithstanding any other provision of this Plan, when the fair market value of a share of the Company's common stock on the date a grantee elects to exercise a stock option is less than such amount per share as may be determined by the Compensation Committee from time to time, the Company may at its election pay the grantee in cash for each share he or she elected to purchase an amount equal to the excess of such fair market value over the option price provided for in the stock option. The Compensation Committee shall periodically determine whether the Company shall make such cash payment upon exercise of a stock option. When the Company makes a payment to the grantee under this paragraph 3 of Article IX, it shall not require the grantee to tender the full purchase price of the shares he or she has elected to purchase, the Company's obligation to issue or deliver such shares shall be null and void, and the right to purchase such number of shares subject to option shall be terminated. Such payment by the Company shall be deemed to be an exercise of a stock option and the purchase of shares thereunder for purposes of paragraph 3 of Article II and Article III.

X. NONTRANSFERABILITY OF GRANTS
During a grantee's lifetime no stock option or stock appreciation right granted under this Plan shall be transferable, and stock options and stock appreciation rights may be exercised only by the grantee, except as may otherwise be provided in rules established by the Compensation Committee to permit transfers or to authorize a third party to act on behalf of the grantee with respect to any stock options or stock appreciation rights.XI. TERMINATION OF EMPLOYMENT

1 The Compensation Committee shall, subject to the provisions of the Plan, determine the rules relating to rights under stock options, stock appreciation rights and restricted grants upon a grantee's termination of employment.

2 A grantee shall forfeit all rights under stock options, stock appreciation rights and restricted stock grants -

(a) if the grantee is dismissed or leaves the service of the plan companies for any reason other than his or her death, or retirement pursuant to the provisions of the pension or retirement plan or policy of a plan company, or

(b) if the grantee retires pursuant to the provisions of the pension or retirement plan or policy of a plan company, and if thereafter the Compensation Committee, after a hearing at which the grantee shall be entitled to be present, shall find that he or she has willfully engaged in any activity which is harmful to the interest of any of such companies;

provided, however, that such stock options, stock appreciation rights and restricted stock grants may continue in effect to such extent and under such conditions as the Compensation Committee may determine; and provided, further, that the Compensation Committee may accelerate or waive any restrictions or conditions applicable to restricted stock grants, in whole or in part, based on such factors and criteria as the Compensation Committee may determine.

3 Upon the death of the grantee or his or her retirement pursuant to the provisions of the pension or retirement plan or policy of a plan company, whichever shall first occur, the number of shares subject to option and the number of stock appreciation rights shall be limited to that number of shares and rights which the grantee could have acquired or exercised under the terms of his or her grant or grants on the date of such death or retirement, and the options or rights representing the remainder of the grant or grants shall terminate.XII. ADJUSTMENTS

1 In the event of any stock dividend, split-up, reclassification or other analogous change in capitalization, the Compensation Committee shall make such adjustments, in the light of the change, as it deems to be equitable, both to the grantees and to the Company, in -

(a) the number of shares and prices per share applicable to outstanding stock options,

(b) the number of outstanding stock appreciation rights and their price,

(c) the number of shares applicable to outstanding restricted stock grants,

(d) the aggregate limitation set forth in Article III with respect to the number of shares which may be made subject to options and restricted stock grants.

Furthermore, in the event of a distribution to common stockholders other than interim or year-end dividends declared as such by the Board of Directors, the Compensation Committee shall make such adjustments, in the light of the distribution, as it deems to be equitable, both to the grantees and to the Company, in respect of the items described in (a), (b) and (c) above.

2 Any fractional shares or fractional stock appreciation rights resulting from adjustments made pursuant to this Article shall be eliminated.

XIII. AMENDMENTS
The Board of Directors reserves the right to modify this Plan from time to time or to repeal the Plan entirely, or to direct the discontinuance of grants either temporarily or permanently; provided, however, that no modification of this Plan shall operate to annul, without the consent of the grantee, a grant already made hereunder; provided, also, that no modification without approval of the stockholders shall -

(a) increase the number of shares which may be made subject to stock options or restricted stock grants, or the number of stock appreciation rights which may be granted under this Plan in the aggregate, except by way of adjustments as provided in Article XII,

(b) permit grant of stock options and stock appreciation rights at a price less than fair market value,

(c) extend the maximum term of stock options and stock appreciation rights, or

(d) permit a grant under this Plan to a member of the Compensation Committee;
except that the Board of Directors may take any action it deems advisable to ensure that qualified stock options may be granted under this Plan in accordance with the provisions of the Internal Revenue Code, as it may be amended.XIV. MISCELLANEOUS

1 The Compensation Committee may adopt such modifications, procedures, and subplans as may be necessary or desirable to comply with provisions of the laws of countries other than the United States in which the Company or a plan company may operate to assure the viability of the benefits of grants made to employees in such countries and to meet the purposes of the Plan.

2 Grantees may use shares of the Company's common stock to satisfy withholding taxes relating to grants under this Plan to the extent provided in terms and conditions established by the Compensation Committee.Exhibit 10.9
