Corning traces its origins to a glass business established in 1851. The present corporation was incorporated in the State of New York in December 1936. The Company’s name was changed from Corning Glass Works to Corning Incorporated on April 28, 1989.

Corning is a global, technology-based corporation that operates in five reportable segments: Display Technologies, Telecommunications, Environmental Technologies, Specialty Materials and Life Sciences. Corning manufactures and processes products at approximately 80 plants in 13 countries.

Corning’s Display Technologies segment manufactures glass substrates for active matrix liquid crystal displays (LCDs), that are used primarily in notebook computers, flat panel desktop monitors, and LCD televisions. Corning’s facilities in Kentucky, Japan, Taiwan, and China and those of Samsung Corning Precision Materials Co., Ltd. (Samsung Corning Precision) in Korea develop, manufacture and supply high quality glass substrates using a proprietary fusion manufacturing process and technology expertise. Corning owns 50% of Samsung Corning Precision, Samsung Electronics Co., Ltd. owns 43% and three other shareholders own the remaining 7%. Samsung Corning Precision sells LCD glass to panel manufacturers in Korea, while panel manufacturers located in Japan, Taiwan, Singapore and China and other leading LCD-producing areas of the world are supplied by Corning. Samsung Corning Precision’s financial statements are attached in Item 15, Exhibits and Financial Statement Schedules.

Corning is a technology leader in this market introducing large-sized glass substrates used by our customers in the production of larger LCDs for monitors and television. We are recognized for providing product innovations that help our customers produce larger, lighter, thinner and higher-resolution displays more affordably. In industry language, glass sizes advance in what are called generations. Glass substrates are currently available from Corning in sizes up to Generation 10 (2,850mm x 3,050mm). Generation 10 glass substrates are produced at an advanced manufacturing facility located at Sharp Corporation’s industrial complex in Sakai City, Japan, which eliminates the need for traditional packaging, shipping, and delivery methods. Large substrates (Generation 5 and higher) allow LCD manufacturers to produce larger and a greater number of panels from each substrate. The larger size leads to economies of scale for LCD manufacturers.

Corning invented its proprietary fusion manufacturing process, which is the cornerstone of the Company’s technology leadership in the LCD industry. The automated process yields high quality glass substrates with excellent dimensional stability and uniformity - essential attributes for the production of increasingly larger, high performance active matrix LCDs. Corning’s fusion process is scalable and is thought to be the most effective process in producing large size substrates. In 2006, Corning launched EAGLE XG^®, the industry’s first environmentally-friendly LCD glass substrate that is free of heavy metals. In 2010, leveraging the EAGLE XG^® composition, Corning introduced EAGLE XG^® Slim glass, a new line of slim glass substrates which enables lighter-weight portable devices and thinner televisions and monitors. In 2011, Corning launched Corning Lotus^™ Glass, an environmentally friendly, high-performance display glass developed to enable cutting-edge technologies, including organic light-emitting diode (OLED) displays and next generation liquid crystal displays (LCD). Corning Lotus Glass helps support the demanding manufacturing processes of both OLED and liquid crystal displays for high performance, portable devices such as smart phones, tablets, and notebook computers.

LCD glass manufacturing is a highly capital intensive business. Corning has made significant investments to expand its LCD glass facilities in response to customer demand. The environment is very competitive. Important attributes for success include efficient manufacturing, access to capital, technology know-how, and patents.

Corning competes across all of its product lines with many large and varied manufacturers, both domestic and foreign. Some of these competitors are larger than Corning, and some have broader product lines. Corning strives to maintain and improve its market position through technology and product innovation. For the future, Corning believes its competitive advantage lies in its commitment to research and development, and its commitment to quality. There is no assurance that Corning will be able to maintain or improve its market position or competitive advantage.

Corning, including Samsung Corning Precision, is the largest worldwide producer of glass substrates for active matrix LCD displays. Corning believes it has sustained its competitive advantages in LCD glass substrate products by investing in new products, such as Corning Lotus glass, providing a consistent and reliable supply and using its proprietary fusion manufacturing process. This process allows us to deliver glass that is larger, thinner and lighter, with exceptional surface quality and without heavy metals. Asahi Glass, Nippon Electric Glass and Avan Strate, Inc. are Corning’s principal competitors in display glass substrates.

Competition within the telecommunications equipment industry is intense among several significant companies. Corning is a leading competitor in the segment’s principal product lines, which include optical fiber and cable, and hardware and equipment. The competitive landscape includes industry consolidation, price pressure and competition for the innovation of new products. These competitive conditions are likely to persist.

Corning believes its large scale manufacturing experience, fiber process, technology leadership and intellectual property assets yield cost advantages relative to several of its competitors. The primary competing producers of optical fiber and cable products are Furukawa Electric/OFS, Fujikura Ltd., Sumitomo Electric and Prysmian Group.

For hardware and equipment products, significant competitors are 3M Company (3M), TE Connectivity, Furukawa OFS and CommScope.

For worldwide automotive ceramic substrate products, Corning has a leading market position that has remained relatively stable over the past year. Corning has also established a strong presence in the heavy duty and light duty diesel vehicle market and believes its competitive advantage in automotive ceramic substrate products for catalytic converters and diesel filter products for exhaust systems is based upon global presence, customer service, engineering design services and product innovation. Corning’s Environmental Technologies products face principal competition from NGK, Denso, and Ibiden.

Corning is one of very few manufacturers with deep capabilities in materials science, optical design, shaping, coating, finishing, metrology, and system assembly. Additionally, we are addressing emerging needs of the consumer electronics industry with the development of chemically strengthened glass. Corning’s Gorilla Glass is an environmentally friendly thin-sheet glass that is better able to survive events that most commonly cause glass failure. Its advanced composition allows a deeper layer of chemical strengthening than is possible with most other chemically strengthened glasses, making it both durable and damage resistant. Our products and capabilities in this segment position the Company to meet the needs of a broad array of markets including aerospace/defense, display, semiconductor, astronomy, vision care, industrial/commercial, and telecommunications. For this segment, Schott, Shin-Etsu Quartz Products, Asahi Fine Glass, Carl Zeiss, Nikon, NEG, Transitions Optical, Oerlikon, Hoya and Heraeus are the main competitors.

Corning is a leading supplier of glass and plastic laboratory products, with a growing plastics products market presence in North America and Europe, and a solid laboratory glass products market presence. Corning seeks to maintain competitive advantages by emphasizing product quality, product availability, supply chain efficiency, a wide product line and superior product attributes. For laboratory products, Greiner, Becton Dickinson, Kimble-Chase, and Duran are the principal worldwide competitors. Corning also faces increasing competition from two large distributors that have pursued backward integration or introduced private label products.

Corning’s production of specialty glasses, ceramics, and related materials requires significant quantities of energy, uninterrupted power sources, certain precious metals, and various batch materials.

Although energy shortages have not been a problem recently, the cost of energy remains volatile. Corning has achieved flexibility through engineering changes to take advantage of low-cost energy sources in most significant processes. Specifically, many of Corning’s principal manufacturing processes can be operated with natural gas, propane, oil or electricity, or a combination of these energy sources.

Availability of resources (ores, minerals, polymers, and processed chemicals) required in manufacturing operations, appears to be adequate. Corning’s suppliers, from time to time, may experience capacity limitations in their own operations, or may eliminate certain product lines. Corning believes it has adequate programs to ensure a reliable supply of batch materials and precious metals. For many products, Corning has alternate glass compositions that would allow operations to continue without interruption in the event of specific materials shortages.

Certain key materials and proprietary equipment used in the manufacturing of products are currently sole-sourced or available only from a limited number of suppliers. Any future difficulty in obtaining sufficient and timely delivery of components could result in lost sales due to delays or reductions in product shipments, or reductions in Corning’s gross margins.

Inventions by members of Corning’s research and engineering staff have been, and continue to be, important to the Company’s growth. Patents have been granted on many of these inventions in the United States and other countries. Some of these patents have been licensed to other manufacturers, including companies in which Corning has equity investments. Many of our earlier patents have now expired, but Corning continues to seek and obtain patents protecting its innovations. In 2011, Corning was granted over 250 patents in the U.S. and over 500 patents in countries outside the U.S.

Each business segment possesses a patent portfolio that provides certain competitive advantages in protecting Corning’s innovations. Corning has historically enforced, and will continue to enforce, its intellectual property rights. At the end of 2011, Corning and its wholly-owned subsidiaries owned over 4,750 unexpired patents in various countries of which about 2,500 were U.S. patents. Between 2012 and 2014, approximately 8% of these patents will expire, while at the same time Corning intends to seek patents protecting its newer innovations. Worldwide, Corning has over 7,400 patent applications in process, with about 1,700 in process in the U.S. Corning believes that its patent portfolio will continue to provide a competitive advantage in protecting Corning’s innovation, although Corning’s competitors in each of its businesses are actively seeking patent protection as well.

For 2011, four customers of the Display Technologies segment accounted for 77% of total segment net sales when combined. In the Telecommunications segment, one customer accounted for 12% of segment net sales. In the Environmental Technologies segment, three customers accounted for 85% of total segment sales in aggregate. In the Specialty Materials segment, two customers accounted for 42% of segment sales in 2011. In the Life Sciences segment, two distributors accounted for 39% of segment sales in 2011. As a result of mergers and consolidations between customers, Corning’s customer base could become more concentrated.

Samsung Corning Precision’s sales were also concentrated in 2011, with sales to two LCD panel makers located in South Korea accounting for approximately 93% of total Samsung Corning Precision sales.

Any positive trends in the sales of LCD glass substrates in previous years may not continue. Our customers are LCD panel and color filter makers. Additionally, consumer preferences for panels of differing sizes, designs, price, or other seasonal factors, may lead to pauses in market growth from time to time. Our customers may not be able to maintain their profitability or access sufficient capital to fund routine maintenance and operations or planned expansions which may limit their pace of orders to us. Emerging material technologies could replace our glass substrates for certain applications resulting in a decline in demand for our LCD products. Existing or new production capacity for glass substrates may exceed the demand for them. Technologies for displays in competition with LCD panels may reduce or eliminate the need for our glass substrates. These technologies may include organic light emitting diodes and plasma display panels. New process technologies developed by our competitors may also place us at a cost or quality disadvantage. Our own process technologies may be acquired or used unlawfully by others, enabling them to compete with us. Our inability to manufacture glass substrates in the sizes and quantities needed by our customers may result in loss of revenue, margins and profits or liabilities for failure to supply. A scarcity of resources, limitations on technology, personnel or other factors resulting in a failure to produce commercial quantities of very large-size glass substrates could have adverse financial consequences to us.

Our Telecommunications segment customers’ purchases of our products are affected by their capital expansion plans, general market and economic uncertainty and regulatory changes, including broadband policy. Sales in the Telecommunications segment are expected to be impacted by the pace of fiber-to-the-premises deployments by our customers such as Bell Canada, Bell Aliant, NBN Co., and Verizon Communications Inc. Our sales will be dependent on planned targets for homes passed and connected. Changes in our customers’ deployment plans could adversely affect future sales in any quarter or for the full year.

In the Environmental Technologies segment, sales of our ceramic substrate and filter products for automotive and diesel emissions are expected to fluctuate with vehicle production. Changes in laws and regulations for air quality and emission controls may also influence future sales. Sales in our Environmental Technologies segment are mainly to three catalyzers and emission system control manufacturers. Our customers sell these systems to automobile and diesel engine original equipment manufacturers. Sales in this segment may be affected by adverse developments in the global vehicle or freight hauling industries or by such factors as higher fuel prices that may affect vehicle sales or downturns in freight traffic.

Certain sales in our Specialty Materials segment track worldwide economic cycles and our customers’ responses to that cycle. In addition, any positive trends in prior years in the sales of strengthened glass for personal handheld devices and LCD television cover glass may not continue. We may experience losses relating to our inability to supply contracted quantities of this glass and processes planned to produce new versions of this glass may not be successful.

Sales in our Life Sciences segment are through two large distributors, and the remaining balance is to a variety of government entities, pharmaceutical and biotechnology companies, hospitals, universities and other research facilities. In 2011, our two largest distributors accounted for 39% of Life Sciences’ segment sales. Changes in our distribution arrangements in this segment may adversely affect this segment’s financial results.

If the markets for our products do not develop and expand as we anticipate, demand for our products may decline, which would negatively impact our operations and financial performance

The markets for our products are characterized by rapidly changing technologies, evolving industry or government standards and new product introductions. Our success is expected to depend, in substantial part, on the successful introduction of new products, or upgrades of current products, and our ability to compete with new technologies. The following factors related to our products and markets, if they do not continue as in the recent past, could have an adverse impact on our operations:

We face pricing pressures in each of our leading businesses that could adversely affect our financial performance

We face pricing pressure in each of our leading businesses as a result of intense competition, emerging new technologies, or over-capacity. While we work consistently toward reducing our costs to offset pricing pressures, we may not be able to achieve proportionate reductions in costs or sustain our current rate of cost reduction. We anticipate pricing pressures will continue in the future in all our businesses.

We have customers and significant operations, including manufacturing and sales, located outside the U.S. We have large manufacturing operations for liquid crystal display glass substrates in Taiwan, China, Japan and Korea, including an equity investment in Samsung Corning Precision operating in South Korea that makes glass substrates for the Korean LCD market. All of our Display segment customers are located in the Asia-Pacific region. As a result of these and other international operations, we face a number of risks, including:

Any of these items could cause our sales or profitability to be significantly reduced.

Additionally, a significant amount of the specialized manufacturing capacity for our Display Technologies segment is concentrated in three overseas countries and it is reasonably possible that the operations of one or more such facilities could be disrupted. Due to the specialized nature of the assets and the customers’ locations, it may not be possible to find replacement capacity quickly or substitute production from facilities in other countries. Accordingly, loss of these facilities could produce a near-term severe impact on our Display business and the Company as a whole.

Because we have significant customers and operations outside the U.S., fluctuations in foreign currencies, especially the Japanese yen, New Taiwan dollar, Korean won, and Euro, affect our sales and profit levels. Foreign exchange rates may make our products less competitive in countries where local currencies decline in value relative to the U.S. dollar and Japanese yen. Sales in our Display Technologies segment, representing 40% of Corning’s sales in 2011, are denominated in Japanese yen. If sales grow in our Display Technologies segment, our exposure to currency fluctuations will increase. Corning hedges significant transaction and balance sheet currency exposures and uses derivative instruments to limit exposure to foreign currency fluctuations associated with certain monetary assets and liabilities as well as operating results. Although we selectively hedge these items, changes in exchange rates (especially the Japanese yen to U.S. dollar) will significantly impact our reported revenues and profits.

If the financial condition of our customers declines, our credit risks could increase

Although we have a rigorous process to administer credit and believe our allowance is adequate, we have experienced, and in the future may experience, losses as a result of our inability to collect our accounts receivable. If our customers or our indirect customers fail to meet their payment obligations for our products, we could experience reduced cash flows and losses in excess of amounts reserved. Many customers of our Display Technologies and Specialty Materials segments are thinly capitalized and/or marginally profitable. In our Environmental Technologies segment, the U.S. auto makers and certain of their suppliers have encountered credit downgrades or have filed for bankruptcy protection. These factors may result in an inability to collect receivables or a possible loss in business.

If we do not successfully adjust our manufacturing volumes and cost structure, or achieve manufacturing yields or sufficient product reliability, our operating results and cash flow could suffer, and we may not achieve anticipated profitability levels

Investments in additional manufacturing capacity of certain businesses, including liquid crystal display glass and diesel emission substrates and filters present challenges. We may face technical and process issues in moving to commercial production and there can be no assurance that Corning will be able to pace its capacity expansion to the actual demand. Economic results may adversely affect our ability to complete planned capacity expansion and products. It is possible that manufacturing capacity may exceed or lag customer demand during certain periods.

The manufacturing of our products involves highly complex and precise processes, requiring production in highly controlled and dust-free environments. Changes in our manufacturing processes could significantly reduce our manufacturing yields and product reliability. In some cases, existing manufacturing may be insufficient to achieve the requirements of our customers. We will need to develop new manufacturing processes and techniques to achieve targeted volume, pricing and cost levels that will permit profitable operations. While we continue to fund projects to improve our manufacturing techniques and processes, we may not achieve satisfactory cost levels in our manufacturing activities that will fully satisfy our profitability targets.

Our future financial performance depends on our ability to purchase a sufficient amount of materials, precious metals, parts, and manufacturing equipment components to meet the demands of our customers

Our ability to meet customer demand depends, in part, on our ability to obtain timely and adequate delivery of materials, precious metals, parts and components from our suppliers. We may experience shortages that could adversely affect our operations. Although we work closely with our suppliers to avoid shortages, there can be no assurances that we will not encounter these problems in the future. Furthermore, certain manufacturing equipment, raw materials or components are available only from a single source or limited sources. We may not be able to find alternate sources in a timely manner. A reduction, interruption or delay of supply, or a significant increase in the price for supplies, such as manufacturing equipment, precious metals, raw materials or energy, could have a material adverse effect on our businesses.

We have incurred, and may in the future incur, restructuring and other charges, the amounts of which are difficult to predict accurately

We have recorded several charges for restructuring, impairment of assets, and the write-off of cost and equity-based investments in the past. In 2011, we recorded a charge for the impairment of certain assets. Certain of our equity affiliates have also recorded restructuring charges. We and our affiliates may have additional actions that result in restructuring charges in the future.

We have incurred, and may in the future incur, goodwill and other intangible asset impairment charges

At December 31, 2011, Corning had goodwill and other intangible assets of $926 million. While we believe the estimates and judgments about future cash flows used in the goodwill impairment tests are reasonable, we cannot provide assurance that future impairment charges will not be required if the expected cash flow estimates as projected by management do not occur, especially if an economic recession occurs and continues for a lengthy period or becomes severe, or if acquisitions and investments made by the Company fail to achieve expected returns.

If our products, including materials purchased from our suppliers, experience performance issues, our business will suffer

Our business depends on the production of products of consistently high quality. Our products, components and materials purchased from our suppliers, are typically tested for quality. These testing procedures are limited to evaluating our products under likely and foreseeable failure scenarios. For various reasons, our products, including materials purchased from our suppliers, may fail to perform as a customer expected. In some cases, product redesigns or additional expense may be required to address such an issue. A significant or systemic product quality issue could result in customer relations problems, lost sales, and financial damages.

We expect that we will face continuous competition from existing competitors, low cost manufacturers and new entrants. We must invest in research and development, expand our engineering, manufacturing and marketing capabilities, and continue to improve customer service and support in order to remain competitive. We cannot provide assurance that we will be able to maintain or improve our competitive position.

We are subject to income taxes in the U.S. and many foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. We regularly are under audit by tax authorities. Although we believe our tax estimates are reasonable, the final determination of tax audits and any related litigation could be materially different from our historical income tax provisions and accruals. The results of an audit or litigation could have a material effect on our financial statements in the period or periods for which that determination is made.

We earn a significant amount of our operating income from outside the U.S., and any repatriation of funds currently held in foreign jurisdictions may result in higher effective tax rates for the company. In addition, there have been proposals to change U.S. tax laws that would significantly impact how U.S. multinational corporations are taxed on foreign earnings. Although we cannot predict whether or in what form this proposed legislation may pass, if enacted it could have a material adverse impact on our tax expense and cash flow.

Changes in our effective tax rate or tax liability may have an adverse effect on our results of operations

Our effective tax rate could be adversely impacted by several factors, some of which are outside of our control, including:

In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. Significant judgment is required in determining our worldwide provision for income taxes. Although we believe our tax estimates are reasonable, the final determination could be materially different from our historical tax provisions and accruals.

Generally accepted accounting principles and accompanying accounting pronouncements, implementation guidelines, and interpretations for many areas of our business, such as revenue recognition, accounting for investments, fair value estimates and accounting for stock options, are very complex and involve significant and sometimes subjective judgments. Changes in these rules or their interpretation could significantly impact our reported earnings and operating income and could add significant volatility to those measures in the future, without a corresponding change in our cash flows.

Our business depends on our ability to attract and retain talented employees

The market for highly skilled workers and leaders in our industry is extremely competitive. We are limited in our ability to recruit internationally by restrictive domestic immigration laws. If we are less successful in our recruiting efforts, or if we are unable to retain key employees, our ability to develop and deliver successful products and services may be adversely affected. Effective succession planning is also important to our long-term success. Failure to ensure effective transfer of knowledge and smooth transitions involving key employees could hinder our strategic planning and execution. The loss of the services of any of our key research and development, engineering or operational personnel or senior management without adequate replacement, or the inability to attract new qualified personnel, could have a material adverse effect on our operations and financial performance.

We are subject to strict environmental regulations and regulatory changes that could result in fines or restrictions that interrupt our operations

Various stages of our manufacturing processes generate chemical waste, waste water and other industrial waste and green-house gases, and we are subject to numerous laws and regulations relating to the use, storage, discharge and disposal of such substances. We have installed anti-pollution equipment for the treatment of chemical waste and waste water at our facilities. We have taken steps to control the amount of greenhouse gases created by our manufacturing operations. However, we cannot provide assurance that environmental claims will not be brought against us or that government regulators will not take steps toward adopting more stringent environment standards.

Any failure on our part to comply with any present or future environmental regulations could result in the assessment of damages or imposition of fines against us, or the suspension/cessation of production or operations. In addition, environmental regulations could require us to acquire costly equipment, incur other significant compliance expenses or limit or restrict production or operations and thus materially and negatively affect our financial condition and results of operations.

Changes in regulations and the regulatory environment in the U.S. and other countries, such as those resulting from the regulation and impact of global warming and CO₂ abatement, may affect our businesses and their results in adverse ways by, among other things, substantially increasing manufacturing costs, limiting availability of scarce resources, especially energy, or requiring limitations on production and sale of our products or those of our customers.

We may experience difficulties in enforcing our intellectual property rights and we may be subject to claims of infringement of the intellectual property rights of others

We may encounter difficulties in protecting our intellectual property rights or obtaining rights to additional intellectual property necessary to permit us to continue or expand our businesses. We cannot assure you that the patents that we hold or may obtain will provide meaningful protection against our competitors. Changes in or enforcement of laws concerning intellectual property, worldwide, may affect our ability to prevent or address the misappropriation of, or the unauthorized use of, our intellectual property. Litigation may be necessary to enforce our intellectual property rights. Litigation is inherently uncertain and the outcome is often unpredictable. Other companies hold patents on technologies used in our industries and are aggressively seeking to expand, enforce and license their patent portfolios.

The intellectual property rights of others could inhibit our ability to introduce new products. We are, and may in the future be, subject to claims of intellectual property infringement or misappropriation that may result in loss of revenue, require us to incur substantial costs, or lead to monetary damages or injunctive relief against us. We cannot assure you as to the outcome of any such claims.

Current or future litigation may harm our financial condition or results of operations

Pending, threatened or future litigation is subject to inherent uncertainties. Our financial condition or results of operations may be adversely affected by unfavorable outcomes, expenses and costs exceeding amounts estimated or insured. In particular, we have been named as a defendant in numerous lawsuits alleging personal injury from exposure to asbestos, and adverse rulings in such lawsuits or the inability to successfully resolve such matters may adversely affect the Company. As described in Legal Proceedings, an amended PCC Plan of Reorganization was filed with the Bankruptcy Court on January 29, 2009 proposing a resolution of PCC asbestos claims. It remains reasonably possible that changes to the amended PCC Plan may be negotiated, and the elements of the plan and its approval are subject to a number of contingencies before the resolution outlined in that Plan becomes final.

We face risks through our equity method investments in companies that we do not control

Corning’s net income includes significant equity earnings from associated companies. For the year ended December 31, 2011, we recognized $1.5 billion of equity earnings, of which 98% came from our two largest investments: Dow Corning (which makes silicone and high purity polycrystalline products) and Samsung Corning Precision (which primarily makes liquid crystal display glass). Samsung Corning Precision is located in the Asia-Pacific region and is subject to political and geographic risks mentioned above, as well as business and other risks within the Display Technologies segment. Our equity investments may not continue to perform at the same levels as in recent years. In 2007, we recognized equity losses associated with Samsung Corning Co., Ltd. (a 50% equity method investment that made glass panels and funnels for conventional televisions), which recorded fixed asset and other impairment charges. Dow Corning emerged from Chapter 11 bankruptcy in 2004 and has certain obligations under its Plan of Reorganization to resolve and fund claims of its creditors and personal injury claimants. Dow Corning may incur further bankruptcy charges in the future, which may adversely affect its operations or assets.

We face the risk of loss resulting from product liability, securities, fiduciary liability, intellectual property, antitrust, contractual, warranty, environmental, fraud and other lawsuits, whether or not such claims are valid. In addition, our product liability, fiduciary, directors and officers, property including business interruption, natural catastrophe and comprehensive general liability insurance may not be adequate to cover such claims or may not be available to the extent we expect in the future. Our insurance costs can be volatile and, at any time, can increase given changes in market supply and demand and our claim history. We may not be able to obtain adequate insurance coverage in the future at acceptable costs. A successful claim that exceeds or is not covered by our policies could require us to pay substantial sums. Some of the carriers in our historical primary and excess insurance programs are in liquidation and may not be able to respond if we should have claims reaching their policies. The financial health of other insurers may deteriorate. Several of our insurance carriers are litigating with us the extent, if any, of their obligation to provide insurance coverage for asbestos liabilities asserted against us. The results of that litigation may adversely affect our insurance coverage for those risks. In addition, we may not be able to obtain adequate insurance coverage for certain types of risk such as political risks, terrorism or war.

Some of our reportable segments operate in industries with a concentrated number of competitors and customers, both foreign and domestic. While we have adopted a corporate-wide compliance program, we may become the subject of antitrust or other governmental investigations from many jurisdictions that may adversely impact our reputation or our ability to make and sell products in the future.

Acquisitions, joint ventures and strategic alliances may have an adverse effect on our business

We expect to continue making acquisitions and entering into joint ventures and strategic alliances as part of our long-term business strategy. These transactions involve significant challenges and risks including that the transaction does not advance our business strategy, that we don’t realize a satisfactory return on our investment, or that we experience difficulty integrating new employees, business systems, and technology, or diversion of management’s attention from our other businesses. It may take longer than expected to realize the full benefits, such as increased revenue, enhanced efficiencies, or market share, or those benefits may ultimately be smaller than anticipated, or may not be realized. These events could harm our operating results or financial condition.

Improper disclosure of personal data could result in liability and harm our reputation

We store and process personally identifiable information of our employees and, in some cases, our customers. At the same time, the continued occurrence of high-profile data breaches provides evidence of an external environment increasingly hostile to breaches of information security. This environment demands that we continuously improve our design and coordination of security controls across our business groups and geographies. Despite these efforts, it is possible our security controls over personal data, our training of employees and vendors on data security, and other practices we follow may not prevent the improper disclosure of personally identifiable information. Improper disclosure of this information could harm our reputation or subject us to liability under laws that protect personal data, resulting in increased costs or loss of revenue.

We maintain an investment portfolio of various holdings, types, and maturities. These investments are subject to general credit, liquidity, market, and interest rate risks, which may be exacerbated by unusual events that have affected global financial markets. A significant part of our investment portfolio consists of U.S. government securities. If global credit and equity markets experience prolonged periods of decline, or if the U.S. federal government budget process results in a default or downgrade of its debt, our investment portfolio may be adversely impacted and we could determine that more of our investments have experienced an other-than-temporary decline in fair value, requiring impairment charges that could adversely impact our financial results.

Security vulnerabilities could lead to reduced revenue, liability claims, or competitive harm

We use electronic information technology (IT) in our manufacturing processes and operations and other aspects of our business. Despite our implementation of security measures, our IT systems are vulnerable to disruptions from computer viruses, natural disasters, unauthorized access, cyber attack and other similar disruptions. A material breach in the security of our IT systems could include the theft of our intellectual property or trade secrets. To the extent that any disruptions or security breaches result in the theft, unauthorized use or publication of our intellectual property and/or confidential business information, it could harm our competitive position, reduce the value of our investment in research and development and other strategic initiatives, or otherwise adversely affect our business.

Additionally, utilities and other operators of critical energy infrastructure that serve our facilities may face heightened security risks, including cyber attacks. In the event of such an attack, disruption in service from our utility providers could disrupt our manufacturing operations which rely on a continuous source of power (electrical, gas, etc).

We operate over 80 manufacturing plants and processing facilities, of which approximately one-third are located in the U.S. We own substantially all of our executive and corporate buildings, which are located in Corning, New York. We also own approximately 90% of our research and development facilities and the majority of our manufacturing facilities. We own approximately 22% of our sales and administrative facilities, while the remaining facilities are leased.

For the years ended 2011, 2010 and 2009 we invested a total of $4.3 billion, primarily in facilities outside of the U.S. in our Display Technologies segment. Of the $2.4 billion spent in 2011, over $1.0 billion was for facilities outside the U.S.

Manufacturing, sales and administrative, and research and development facilities have an aggregate floor space of approximately 25 million square feet. Distribution of this total area follows:

Total assets and capital expenditures by operating segment are included in Note 20 (Reportable Segments) to the Consolidated Financial Statements. Information concerning lease commitments is included in Note 14 (Commitments, Contingencies, and Guarantees) to the Consolidated Financial Statements.

In the fourth quarter of 2011, as a result of excess glass capacity in the market, we announced plans to reduce worldwide glass capacity in our Specialty Materials and Display Technologies segments by approximately 25%. These actions impact Corning Gorilla Glass capacity and LCD glass manufacturing capacity at both our wholly-owned LCD glass business and at our equity affiliate Samsung Corning Precision, and include delaying the start up of the new tanks, as well as postponing the relight of tanks that were under repair. Samsung Corning Precision also shut down several active tanks. Additionally, Corning recorded an impairment charge in the amount of $130 million in the fourth quarter of 2011 related to certain assets located in Japan used in the ion exchange process for the production of large cover glass. The large cover glass impairment charge represents a write-down of assets specific to the glass-strengthening process for large size cover glass to their relative fair market values as of the date of impairment. This asset group includes machinery and equipment used in the ion exchange process and facilities dedicated to the ion exchange process. Refer to Note 9 (Property, Net of Accumulated Depreciation) and Note 16 (Fair Value Measurements) to the Consolidated Financial Statements for additional information.

Environmental Litigation. Corning has been named by the Environmental Protection Agency (the Agency) under the Superfund Act or by state governments under similar state laws, as a potentially responsible party for 18 hazardous waste sites. Under the Superfund Act, all parties who may have contributed any waste to a hazardous waste site, identified by the Agency, are jointly and severally liable for the cost of cleanup unless the Agency agrees otherwise. It is Corning’s policy to accrue for its estimated liability related to Superfund sites and other environmental liabilities related to property owned by Corning based on expert analysis and continual monitoring by both internal and external consultants. At December 31, 2011 and 2010, Corning had accrued approximately $25 million (undiscounted) and $30 million (undiscounted), respectively, for the estimated liability for environmental cleanup and related litigation. Based upon the information developed to date, management believes that the accrued reserve is a reasonable estimate of the Company’s liability and that the risk of an additional loss in an amount materially higher than that accrued is remote.

Dow Corning Corporation. Corning and The Dow Chemical Company (Dow Chemical) each own 50% of the common stock of Dow Corning. In May 1995, Dow Corning filed for bankruptcy protection to address pending and claimed liabilities arising from many thousands of breast implant product lawsuits. On June 1, 2004, Dow Corning emerged from Chapter 11 with a Plan of Reorganization (the Plan) which provided for the settlement or other resolution of implant claims. The Plan also includes releases for Corning and Dow Chemical as shareholders in exchange for contributions to the Plan.

Under the terms of the Plan, Dow Corning has established and is funding a Settlement Trust and a Litigation Facility to provide a means for tort claimants to settle or litigate their claims. Inclusive of insurance, Dow Corning has paid approximately $1.7 billion to the Settlement Trust. As of December 31, 2011, Dow Corning had recorded a reserve for breast implant litigation of $1.6 billion. As a separate matter arising from the bankruptcy proceedings, Dow Corning is defending claims asserted by a number of commercial creditors who claim additional interest at default rates and enforcement costs, during the period from May 1995 through June 2004. As of December 31, 2011, Dow Corning has estimated the liability to commercial creditors to be within the range of $86 million to $280 million. As Dow Corning management believes no single amount within the range appears to be a better estimate than any other amount within the range, Dow Corning has recorded the minimum liability within the range. Should Dow Corning not prevail in this matter, Corning’s equity earnings would be reduced by its 50% share of the amount in excess of $86 million, net of applicable tax benefits. In addition, the London Market Insurers (the LMI Claimants) claimed a reimbursement right with respect to a portion of insurance proceeds previously paid by the LMI Claimants to Dow Corning. This claim was based on a theory that the LMI Claimants overestimated Dow Corning’s liability for the resolution of implant claims pursuant to the Plan. Based on settlement negotiations, Dow Corning had estimated that the most likely outcome would result in payment to the LMI Claimants in a range of $10 million to $20 million. During the third quarter, Dow Corning and the LMI Claimants settled the claim for an amount within that range. There are a number of other claims in the bankruptcy proceedings against Dow Corning awaiting resolution by the U.S. District Court, and it is reasonably possible that Dow Corning may record bankruptcy-related charges in the future. The remaining tort claims against Corning are expected to be channeled by the Plan into facilities established by the Plan or otherwise defended by the Litigation Facility.

Hemlock Semiconductor Group, of which Dow Corning owns 63%, brought an action against one of its customers to enforce multiyear supply agreements requiring the customer to purchase or pay for quantities of polycrystalline silicon used in the solar power industry. Hemlock Semiconductor Group and the customer resolved the dispute during the fourth quarter. The settlement resulted in Dow Corning recognizing pre-tax income of approximately $420 million for the year ended December 31, 2011, including previously deferred revenue. After income taxes and amounts attributable to non-controlling interests, net income attributable to Dow Corning for the year ended December 31, 2011, increased by approximately $177 million from this settlement.

Pittsburgh Corning Corporation. Corning and PPG Industries, Inc. (PPG) each own 50% of the capital stock of Pittsburgh Corning Corporation (PCC). Over a period of more than two decades, PCC and several other defendants have been named in numerous lawsuits involving claims alleging personal injury from exposure to asbestos. On April 16, 2000, PCC filed for Chapter 11 reorganization in the U.S. Bankruptcy Court for the Western District of Pennsylvania. At the time PCC filed for bankruptcy protection, there were approximately 11,800 claims pending against Corning in state court lawsuits alleging various theories of liability based on exposure to PCC’s asbestos products and typically requesting monetary damages in excess of one million dollars per claim. Corning has defended those claims on the basis of the separate corporate status of PCC and the absence of any facts supporting claims of direct liability arising from PCC’s asbestos products. Corning is also currently involved in approximately 9,900 other cases (approximately 38,300 claims) alleging injuries from asbestos and similar amounts of monetary damages per case. Those cases have been covered by insurance without material impact to Corning to date. As described below, several of Corning’s insurance carriers have filed a legal proceeding concerning the extent of any insurance coverage for these claims. Asbestos litigation is inherently difficult, and past trends in resolving these claims may not be indicators of future outcomes.

Corning, with other relevant parties, has been involved in ongoing efforts to develop a Plan of Reorganization that would resolve the concerns and objections of the relevant courts and parties. In 2003, a plan was agreed to by various parties (the 2003 Plan), but, on December 21, 2006, the Bankruptcy Court issued an order denying the confirmation of that 2003 Plan. On January 29, 2009, an amended plan of reorganization (the Amended PCC Plan) - which addressed the issues raised by the Court when it denied confirmation of the 2003 Plan - was filed with the Bankruptcy Court.

The proposed resolution of PCC asbestos claims under the Amended PCC Plan would have required Corning to contribute its equity interests in PCC and Pittsburgh Corning Europe N.V. (PCE), a Belgian corporation, and to contribute a fixed series of payments, recorded at present value. Corning would have had the option to use its shares rather than cash to make these payments, but the liability would have been fixed by dollar value and not the number of shares. The Amended PCC Plan would, originally, have required Corning to make (1) one payment of $100 million one year from the date the Amended PCC Plan becomes effective and certain conditions are met and (2) five additional payments of $50 million, on each of the five subsequent anniversaries of the first payment, the final payment of which is subject to reduction based on the application of credits under certain circumstances. Documents were filed with the Bankruptcy Court further modifying the Amended PCC Plan by reducing Corning’s initial payment by $30 million and reducing its second and fourth payments by $15 million each. In return, Corning would relinquish its claim for reimbursement of its payments and contributions under the Amended PCC Plan from the insurance carriers involved in the bankruptcy proceeding with certain exceptions.

On June 16, 2011, the Court entered an Order denying confirmation of the Amended PCC Plan. The Court’s memorandum opinion accompanying the order rejected some objections to the Amended PCC Plan and made suggestions regarding modifications to the Amended PCC Plan that would allow the Plan to be confirmed. Corning and other parties have filed a motion for reconsideration, objecting to certain points of this Order. Certain parties to the proceeding filed specific plan modifications in response to the Court’s opinion and Corning supported these filings. Corning and other parties also filed a motion for reconsideration objecting to certain points in the Court’s opinion and Order. Proposed plan modifications will be discussed during the hearing scheduled for February 17, 2012.

The Amended PCC Plan does not include certain non-PCC asbestos claims that may be or have been raised against Corning. Corning has recorded an additional $150 million for such claims in its estimated asbestos litigation liability. The liability for non-PCC claims was estimated based upon industry data for asbestos claims since Corning does not have recent claim history due to the injunction issued by the Bankruptcy Court. The estimated liability represents the undiscounted projection of claims and related legal fees over the next 20 years. The amount may need to be adjusted in future periods as more data becomes available.

The Amended PCC Plan with the modifications addressing issues raised by the Court’s June 16 opinion remains subject to a number of contingencies. Payment of the amounts required to fund the Amended PCC Plan from insurance and other sources are subject to a number of conditions that may not be achieved. The approval of the (further modified) Amended PCC Plan by the Bankruptcy Court is not certain and faces objections by some parties. If the modified Amended PCC Plan is approved by the Bankruptcy Court, that approval will be subject to appeal. For these and other reasons, Corning’s liability for these asbestos matters may be subject to changes in subsequent quarters. The estimate of the cost of resolving the non-PCC asbestos claims may also be subject to change as developments occur. Management continues to believe that the likelihood of the uncertainties surrounding these proceedings causing a material adverse impact to Corning’s financial statements is remote.

Several of Corning’s insurers have commenced litigation in state courts for a declaration of the rights and obligations of the parties under insurance policies, including rights that may be affected by the potential resolutions described above. Corning is vigorously contesting these cases. Management is unable to predict the outcome of this insurance litigation and therefore cannot estimate the range of any possible loss.

Seoul Guarantee Insurance Co. and other creditors against Samsung Group and affiliates. Prior to their merger, Samsung Corning Precision Materials Co., Ltd. (Samsung Corning Precision) and Samsung Corning Co. Ltd. (Samsung Corning) were two of approximately thirty co-defendants in a lawsuit filed by Seoul Guarantee Insurance Co. and thirteen other creditors (SGI and Creditors) for alleged breach of an agreement that approximately twenty-eight affiliates of the Samsung group (Samsung Affiliates) entered into with SGI and Creditors on August 24, 1999 (the Agreement). The lawsuit is pending in the courts of South Korea. Under the Agreement, it is alleged that the Samsung Affiliates agreed to sell certain shares of Samsung Life Insurance Co., Ltd. (SLI), which had been transferred to SGI and Creditors in connection with the petition for court receivership of Samsung Motors Inc. In the lawsuit, SGI and Creditors allege a breach of the Agreement by the Samsung Affiliates and are seeking the loss of principal (approximately $1.95 billion) for loans extended to Samsung Motors Inc., default interest and a separate amount for breach. On January 31, 2008, the Seoul District Court ordered the Samsung Affiliates: to pay approximately $1.3 billion by disposing of 2,334,045 shares of SLI less 1,165,955 shares of SLI previously sold by SGI and Creditors and paying the proceeds to SGI and Creditors; to satisfy any shortfall by participating in the purchase of equity or subordinate debentures issued by them; and pay default interest of 6% per annum. The ruling was appealed. On November 10, 2009, the Appellate Court directed the parties to attempt to resolve this matter through mediation. On January 11, 2011, the Appellate Court ordered the Samsung Affiliates to pay 600 billion won in principal and 20 billion won in delayed interest to SGI and Creditors. Samsung promptly paid those amounts, which approximated $550 million when translated to United States dollars, from a portion of an escrow account established upon completion of SLI’s initial public offering (IPO) on May 7, 2010. On February 7, 2011, the Samsung Affiliates appealed the Appellate Court’s ruling to the Supreme Court of Korea and the appeal is currently in progress. Samsung Corning Precision has not contributed to any payment related to these disputes, and has concluded that no provision for loss should be reflected in its financial statements. Other than as described above, no claim in these matters has been asserted against Corning or any of its affiliates.

Ellsworth Industrial Park, Downers Grove, IL Environmental Litigation. Corning has settled claims for contribution for personal injury and property damage arising from the alleged release of solvents from the operations of several corporate defendants at the Ellsworth Industrial Park into soil and groundwater. Corning has also settled a cost-recovery action by the State of Illinois against a number of corporate defendants as a result of an alleged groundwater contamination at this industrial park site. Two additional corporate defendants have made claims for contribution for property damage and cost recovery for remediations at this industrial park site, one of which has been voluntarily dismissed as to Corning. The second case was dismissed by the Court on August 12, 2009. On November 17, 2009, the Court denied plaintiff’s request to file an amended complaint. On December 14, 2009, plaintiff gave notice of its appeal of the District Court’s opinion and order dismissing its case to the U.S. Court of Appeals for the Seventh Circuit. On November 10, 2010, the Court of Appeals reversed the District Court and reinstated the case. At a February 3, 2011 status conference, the District Court set a date for responses to plaintiff’s complaint. On March 7, 2011, Corning filed a motion to dismiss the complaint. On August 11, 2011, the District Court granted Corning’s motion to dismiss. On August 15, 2011, the case was settled by agreement with respect to Corning’s subsidiary, H.W. Holding Co. On October 31, 2011, the District Court dismissed the case with prejudice pursuant to the settlement agreement.

Supply Disputes. Corning has notified customers of its Environmental Technologies segment that it will be unable to fully supply all future requests for certain diesel products, but will honor its existing legal obligations. At least one customer has taken the position that Corning has a legal obligation to supply its requirements for these products for some time in the future despite the absence of an executed supply agreement or accepted purchase orders. In response, Corning has indicated it does not agree with the customer’s position and Corning is under no current obligation to provide these products in the future to that customer. Corning filed an action for a declaratory judgment in the Western District of New York seeking confirmation of Corning’s position on these issues. The parties have since resolved the supply issues and Corning voluntarily dismissed the declaratory judgment complaint on December 6, 2011. Corning continues to discuss an appropriate resolution of supply matters with other customers.

Chinese Antidumping Investigation. On April 22, 2010, the Chinese Ministry of Commerce initiated an antidumping investigation against manufacturers of optical fiber based in the U.S. and the European Union, alleging that standard single-mode optical fiber was sold in China at lower prices than in the respective home country. This matter does not present a claim for damages, but the Ministry may prospectively impose additional duties on imported fiber products. On April 21, 2011, the Chinese authorities issued a final decision finding a dumping margin of approximately 5.4% on certain optical fiber imported by Corning into China, having previously rejected Corning’s arguments against the imposition of such duties.

Demodulation, Inc. On January 18, 2011, Demodulation, Inc. filed suit in the U.S. District Court for the District of New Jersey against Applied DNA Sciences, Inc., Corning Incorporated, Alfred University, Alfred Technology Resources, Inc., and John and Jane Does 1-10. Demodulation filed an amended complaint on August 3, 2011, alleging a conspiracy by the defendants to steal Demodulation’s alleged trade secrets and other intellectual property related to glass covered amorphous metal microwires and seeks damages under various theories, including breach of contract, defamation, conspiracy, antitrust, unfair competition, interference with prospective business relations and misappropriation of trade secrets. Corning does not believe Demodulation’s allegations have merit and intends to defend the case vigorously. Recognizing that the outcome of litigation is uncertain, management believes that the likelihood of a materially adverse impact to Corning’s financial statements is remote.

Trade Secret Misappropriation Suits Concerning LCD Glass Technology. On July 18, 2011, in China, Corning Incorporated filed suit in the Beijing Second Intermediate People’s Court against Hebei Dongxu Investment Group Co., Ltd., which changed its name to Dongxu Group Co., Ltd. (Dongxu) for misappropriation of certain trade secrets related to the fusion draw process for manufacturing glass substrates used in active matrix liquid crystal displays (LCDs). Dongxu has filed an appeal to contest jurisdiction. On July 18, 2011, in Korea, Corning Incorporated and Samsung Corning Precision Materials Co., Ltd. (Samsung Corning Precision) filed suits in the Daejeon District Court against Dongxu, one of its officers, and two other named individuals, for related trade secret misappropriation. Samsung Corning Precision is an equity company between Corning and Samsung Electronics Co., Ltd., which uses Corning LCD glass technology under license agreements with Corning. In these actions, Corning is seeking monetary damages and orders restraining Dongxu from using, disclosing, or permitting others to use, misappropriated Corning LCD glass manufacturing technology. Two of the individuals named in the Korean suit were previously convicted in Seoul Southern District Court on January 22, 2009, for the theft of certain Corning LCD glass technology that was being used by Samsung Corning Precision.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Management’s Discussion and Analysis provides a historical and prospective narrative on the Company’s financial condition and results of operations. This discussion includes the following sections:

Although Corning’s net income declined in 2011 when compared to 2010, the majority of our segments experienced healthy sales growth, despite the challenging 2011 economic environment. The largest driver of Corning’s sales increase was the robust retail demand for portable display devices that utilize our Corning Gorilla Glass. Our Telecommunications segment also experienced significant sales growth in 2011 due to strong fiber-to-the-premises, enterprise network products, and optical fiber and cable sales. In addition, sales increased 22% in 2011 in our Environmental Technologies segment, reflecting increased demand worldwide for automotive and diesel products. Sales in the Life Sciences segment were higher primarily due to an increase in demand for the segment’s legacy products, combined with the impact of a small acquisition completed in the fourth quarter of 2010. Sales in our Display Technologies segment were only slightly higher in 2011 when compared to the prior year, reflecting volume growth and favorable movements in foreign exchange rates, offset by significantly lower prices. Results in this segment reflect the excess glass capacity in the market, driven by lower than anticipated worldwide glass volume growth in 2011. Corning is addressing the current imbalance between glass supply and demand by reducing worldwide glass capacity in our Display Technologies and Specialty Materials segments by approximately 25%, impacting LCD glass capacity as well as Corning Gorilla Glass capacity.

For the year ended December 31, 2011, we generated net income of $2.8 billion or $1.77 per share compared to net income of $3.6 billion or $2.25 per share for 2010. When compared to last year, the decrease in net income was due largely to the following items:

The decrease in net income in 2011 was offset somewhat from the favorable impact of movements in foreign exchange rates in the amount of $219 million, and higher net income in our Telecommunications and Environmental Technologies segments.

Corning remains committed to a strategy of growing through global innovation while preserving our independence. This strategy has served us well. Our key priorities for 2011 were similar to those in prior years: protect our financial health and invest in the future. During 2011, we made the following progress on these priorities:

Our financial position remained sound and we delivered strong cash flows from operating activities. Significant items in 2011 included the following:

We continue to focus on the future and on what we do best – creating keystone components that enable high-technology systems. We remain committed to investing in research, development and engineering to drive innovation. We continue to work on new products, including glass substrates for high performance displays, OLED and LCD applications, diesel filters and substrates, and the optical fiber, cable and hardware and equipment that enable fiber-to-the-premises, and next generation data centers. In addition, in 2011, we increased our focused on wireless solutions for diverse venue applications such as Distributed Antenna Systems, fiber-to-the-cell and antennas. We have increased our research, development and engineering spending to support the advancement of new product attributes for our Corning Gorilla Glass suite of products. We will continue to focus on adjacent glass opportunities, including products such as glass substrates for thin-film photovoltaics in solar applications, which leverage existing materials or manufacturing processes.

Our research, development and engineering expenditures increased by $68 million in 2011 when compared to 2010, but remained relatively constant as a percentage of net sales. We believe our spending levels are appropriate to support our technology and innovation strategies.

Capital spending increased significantly in 2011 when compared to 2010, largely as a result of several multi-year investment plans announced in 2010 that will increase manufacturing capacity in several of our reportable segments. Specifically, the increase in spending in 2011 was driven by construction costs for an LCD glass substrate facility in China for our Display Technologies segment and a capacity expansion project for Specialty Materials’ Corning Gorilla Glass in Japan. Capital expenditures in 2011 also include spending in the Environmental Technologies segment to expand its existing automotive substrate facilities in Shanghai, China and Kaiserslautern, Germany, and in the Life Sciences segment to establish a manufacturing and distribution facility in WuJiang, China. Total capital expenditures for 2011 were $2.4 billion. In 2011, approximately $1.3 billion was invested in our Display Technologies segment and approximately $348 million was invested in our Specialty Materials segment.

We expect our 2012 capital spending to be about $1.8 billion. Approximately $800 million will be allocated to our Display Technologies segment, of which approximately $400 million will be related to 2011 capital projects.

Corning expects moderate sales growth in 2012, led by an increase in demand in our Telecommunications and Environmental Technologies segments. We believe worldwide demand for LCD glass in 2012 will increase from 3.2 billion square feet to approximately 3.6 billion square feet when compared to 2011, driven by the combination of an increase in retail sales of LCD televisions and the demand for larger television screen sizes, coupled with growth in the personal computer market. We expect cumulative double-digit price declines in our Display segment over the two-quarter period beginning in the fourth quarter of 2011. We are hopeful that sequential quarterly price declines in 2012 will be moderate. Net income will be negatively impacted by lower equity earnings from our equity affiliate Dow Corning, driven by lower demand and price declines in both silicone products and at Hemlock Semiconductor Group, Dow Corning’s consolidated subsidiary that makes high purity polycrystalline silicon for the semiconductor and solar industries. We may take advantage of acquisition opportunities that support the long-term strategies of our businesses. We remain confident that our strategy to grow through global innovation, while preserving our financial stability, will enable our continued long-term success.

Selected highlights from our continuing operations follow (dollars in millions):

Net sales in 2011 increased 19% when compared to the prior year, due to sales growth in all of our segments, with the largest increases occurring in the Specialty Materials, Telecommunications and Environmental segments. Sales in the Specialty Materials segment increased by 86%, due to the strong demand for Corning Gorilla Glass that is used as cover glass in portable handheld display devices, tablets and notebook computers. Telecommunications segment sales increased due to strength across all of their product lines, most significantly in optical fiber and cable and fiber-to-the-premises products. Sales in the Environmental Technologies segment were higher, driven by higher demand for our diesel products. Additionally, the net positive impact of movements in foreign exchange rates impacted sales in the amount of $345 million.

Net sales in 2010 increased 23% due to higher sales in all of our segments when compared to 2009, driven by volume growth in all of our segments and from the net positive impact of movements in foreign exchange rates. We saw demand increase for all of our LCD products, led by strong growth of LCD televisions outside of the United States. Sales in our Specialty Materials segment in 2010 increased 75% when compared to 2009, due to strong demand for Corning Gorilla Glass products. Sales were also strong in both our Environmental Technologies and Life Sciences segments, up 38% and 39%, respectively.

In 2011, net sales into international markets accounted for 78% of net sales. For 2010 and 2009, net sales into international markets accounted for 74% and 76%, respectively, of net sales.

The types of expenses included in the cost of sales line item are: raw materials consumption, including direct and indirect materials; salaries, wages and benefits; depreciation and amortization; production utilities; production-related purchasing; warehousing (including receiving and inspection); repairs and maintenance; inter-location inventory transfer costs; production and warehousing facility property insurance; rent for production facilities; and other production overhead.

For 2011, gross margin dollars increased when compared to 2010, but declined slightly as a percentage of sales. Improvements in gross margin were driven by the impact of strong sales in the Specialty Materials segment, along with volume increases and manufacturing efficiency gains in the Environmental Technologies segment. Offsetting these gains was the impact of significant price declines in our Display Technologies segment.

For 2010, gross margin dollars and as a percentage of net sales increased significantly when compared to 2009, due primarily to the impact of volume increases in the Display Technologies segment, offset somewhat by price declines. Improvements were also driven by strong sales in the Environmental Technologies and Specialty Materials segments, as well as cost reduction efforts and manufacturing efficiency improvements.

Selling, general, and administrative expenses for 2011 increased slightly when compared to 2010, due primarily to an increase in salaries, partially as a result of three small acquisitions completed within the past 15 months, offset by an adjustment to performance-based compensation costs and a credit of $27 million resulting from a reduction in a contingent liability associated with an acquisition recorded in the first quarter of 2011. As a percentage of net sales, selling, general, and administrative expenses in 2011 were down considerably when compared to 2010, because the rate of increase in sales exceeded the rate of increase in spending for selling, general, and administrative costs.

Selling, general, and administrative expenses for 2010 were up when compared to 2009, due primarily to higher compensation-related costs and the costs of integrating new businesses, offset by the impact of restructuring actions completed in 2009. As a percentage of net sales, selling, general, and administrative expenses in 2010 were down slightly when compared to 2009, because the rate of increase in sales exceeded the rate of increase in spending for selling, general, and administrative costs.

The types of expenses included in the selling, general and administrative expenses line item are: salaries, wages and benefits; travel; sales commissions; professional fees; and depreciation and amortization, utilities, and rent for administrative facilities.

Research, development and engineering expenses for 2011 increased by $68 million to $671 million in 2011 when compared to 2010, but remained relatively constant as a percentage of net sales. Corning’s research, development and engineering expenses are currently focused on our Specialty Materials and Telecommunications segments as we strive to capitalize on growth opportunities in those segments. We believe our spending levels are adequate to support our technology and innovation strategies.

Research, development and engineering expenses increased by $40 million in 2010 when compared to 2009, but declined slightly as a percentage of net sales. Increased spending in 2010 was driven primarily by the Display Technologies, Environmental Technologies and Telecommunications segments.

Corning recorded restructuring, impairment, and other charges and credits in 2011, 2010 and 2009, which affect the comparability of our results for the periods presented. A description of those charges and credits follows:

In the fourth quarter of 2011, Corning recorded an impairment charge in the amount of $130 million related to certain assets located in Japan used in the ion exchange process for the production of large cover glass. Large cover glass is primarily used as a cover sheet of strengthened glass for frameless (bezel-less) LCD displays. The large cover glass impairment charge represents a write-down of assets specific to the glass-strengthening process for large size cover glass to their relative fair market values as of the date of impairment. This asset group includes machinery and equipment used in the ion exchange process and facilities dedicated to the ion exchange process. Additional information on the asset impairment is found in Note 9 (Property, Net of Accumulated Depreciation) and Note 16 (Fair Value Measurements) to the Consolidated Financial Statements.

In the fourth quarter of 2010, we recorded $324 million in other credits as settlement of business interruption and property damage insurance claims resulting from two events which impacted production at several of our LCD glass manufacturing facilities. In August 2009, an earthquake halted production at one of our LCD glass manufacturing facilities in Japan and in October 2009, production at our facility in Taichung, Taiwan was impacted by a power disruption.

In response to anticipated lower sales in 2009, we recorded charges of $228 million primarily for a corporate-wide restructuring plan to reduce our global workforce. The charges included costs for severance, special termination benefits, outplacement services, and the impact of a $32 million curtailment loss for postretirement benefits in 2009. Total cash expenditures associated with these actions were approximately $150 million, with the majority of spending for employee-related costs completed by 2010 and payments for exit activities substantially completed by the end of 2011. Annualized savings from these actions are about $224 million and are reflected largely in cost of sales and selling, general, and administrative expenses.

In 2011, we recorded an increase to our asbestos litigation liability of $24 million compared to a net decrease in 2010 of $49 million. The net decrease in 2010 was due primarily to a $54 million decrease to our estimated liability for asbestos litigation that was recorded in the first quarter of 2010, as a result of the change in terms of the proposed settlement of the PCC asbestos claims. For the remainder of 2010, we recorded net credit adjustments to our asbestos litigation liability of $5 million to reflect the change in value of the estimated settlement liability. In 2009, we recorded an increase to our asbestos litigation liability of $20 million.

Our asbestos litigation liability was estimated to be $657 million at December 31, 2011, compared with an estimate of $633 million at December 31, 2010. The entire obligation is classified as a non-current liability as installment payments for the cash portion of the obligation are not planned to commence until more than 12 months after the proposed Amended PCC Plan is ultimately effective, and a portion of the obligation fulfilled through the direct contribution of Corning’s investment in PCE (currently recorded as a non-current other equity method investment).

The following provides a summary of equity earnings of affiliated companies, net of impairments (in millions):

Equity earnings of affiliated companies decreased in 2011, reflecting lower earnings performance at both Samsung Corning Precision and at Dow Corning, when compared to last year.

The change in equity earnings from Samsung Corning Precision is explained more fully in the discussion of the performance of the Display Technologies segment and in All Other.

Equity earnings from Dow Corning were lower in 2011 when compared to 2010. The decline in equity earnings was largely due to the following items:

The decrease in equity earnings from Dow Corning was partially offset by a gain in the amount of $89 million associated with the resolution of a contract dispute by Dow Corning’s consolidated subsidiary, Hemlock Semiconductor Group (Hemlock), a producer of high purity polycrystalline silicon for the semiconductor and solar industries, against one of its customers relating to enforcement of long-term supply agreements.

In the second half of 2011, Dow Corning began experiencing unfavorable industry conditions at Hemlock. Declines in governmental subsidies in the solar panel industry, especially in Europe, and over-capacity at all levels of the solar supply chain led to significant declines in polycrystalline spot prices. The decline in spot prices was large enough to potentially induce Hemlock customers to default on their long term contracts. In response, Hemlock modified a number of sales agreements to provide temporary pricing relief while preserving the long-term favorable relationships with its customers. In addition, Hemlock decided to delay certain plant expansion activities until market conditions for polycrystalline silicon have improved. Prices for polycrystalline silicon are expected to remain at these substantially lower levels throughout 2012, negatively impacting profitability at Hemlock and resulting in lower equity earnings from Dow Corning in 2012 when compared to 2011.

The increase in equity earnings from Dow Corning in 2010 when compared to 2009 was primarily due to the following items:

“Other income (expense), net” in Corning’s consolidated statements of income includes the following (in millions):

In addition to the items identified under Gross margin, Restructuring, impairment and other charges (credits), Asbestos litigation charge (credit), and Other income, net, movements in foreign exchange rates also impacted results for the years presented. In 2011, Income before income taxes included $256 million from the positive impact of movements in foreign exchange rates when compared to 2010. In 2010, Income before income taxes included $229 million for the positive impact of movements in foreign exchange rates when compared to the previous year.

Our provision (benefit) for income taxes and the related effective income tax rates were as follows (in millions):

The effective income tax rate for 2011 differed from the U.S. statutory rate of 35% primarily due to the following items:

The effective income tax rate for 2010 differed from the U.S. statutory rate of 35% primarily due to the following items:

The effective income tax rate (benefit) for 2009 differed from the U.S. statutory rate of 35% primarily due to the following items:

Corning has valuation allowances on certain shorter-lived deferred tax assets such as those represented by capital loss carry forwards and state tax net operating loss carry forwards, as well as other foreign net operating loss carry forwards and federal and state tax credits, because we cannot conclude that it is more likely than not that we will earn income of the character required to utilize these assets before they expire. U.S. profits of approximately $7.8 billion will be required to fully realize the deferred tax assets as of December 31, 2011. Of that amount, $4.2 billion of U.S. profits will be required over the next 14 years to fully realize the deferred tax assets associated with federal net operating loss carry forwards. The remaining deferred tax assets will be realized as the underlying temporary differences reverse over an extended period. The amount of U.S. and foreign deferred tax assets that had valuation allowances at December 31, 2011 and 2010 was $219 million and $214 million, respectively.

We currently provide income taxes on the earnings of foreign subsidiaries and affiliated companies to the extent these earnings are currently taxable or expected to be remitted. As of December 31, 2011, taxes have not been provided on approximately $10.8 billion of accumulated foreign unremitted earnings that are expected to remain invested indefinitely. It is not practical to calculate the unrecognized deferred tax liability on those earnings.

Certain foreign subsidiaries in China and Taiwan are operating under tax holiday arrangements. The nature and extent of such arrangements vary, and the benefits of such arrangements phase out through 2015 according to the specific terms and schedules of the relevant taxing jurisdictions. The impact of the tax holidays on our effective rate is a reduction in the rate of 2.0, 3.1 and 7.3 percentage points for 2011, 2010 and 2009, respectively.

While we expect the amount of unrecognized tax benefits to change in the next 12 months, we do not expect the change to have a significant impact on the results of operations or our financial position.

Refer to Note 6 (Income Taxes) to the Consolidated Financial Statements for further details regarding income tax matters.

As a result of the items discussed above, net income and per share data was as follows (in millions, except per share amounts):

All other reportable segments that do not meet the quantitative threshold for separate reporting have been grouped as “All Other”. This group is primarily comprised of development projects and results for new product lines.

We prepared the financial results for our segments on a basis that is consistent with the manner in which we internally disaggregate financial information to assist in making internal operating decisions. We included the earnings of equity affiliates that are closely associated with our reportable segments in the respective segment’s net income. We have allocated certain common expenses among our reportable segments differently than we would for stand-alone financial information. Segment net income may not be consistent with measures used by other companies. The accounting policies of our reportable segments are the same as those applied in the consolidated financial statements.

Effective January 1, 2009, we began providing U.S. income tax expense (or benefit) on U.S. earnings (losses) due to the change in our conclusion about the realizability of our U.S. deferred tax assets in 2008. As a result of the change in our tax position, we adjusted the allocation of taxes to our reportable segments in 2009 to reflect this difference. The impact of changing our allocation methodology was not significant.

The end market for LCD televisions was up slightly, with unit growth rates remaining consistent with or exceeding our expectations across all geographic regions. Additionally, larger-sized LCD televisions were the fastest growing size category in 2011 and have resulted in area growth rates that were even higher than unit growth rates. However, because Corning sells to panel makers and not to end market consumers, supply chain expansion and contraction for this industry are key factors in Corning’s sales volume. While end market demand continues to grow in all LCD applications, inventory levels within the LCD supply chain have not kept pace with this growth, and have, in fact, declined in absolute terms during 2011 when compared to 2010, resulting in lower volume and excess capacity in the supply chain. As a result, Corning announced in the fourth quarter of 2011 that it would reduce capacity at our wholly-owned business by delaying the start-up of new glass melting tanks, as well as postponing the relight of tanks that were removed from service for normal repair. Our equity affiliate, Samsung Corning Precision, took similar actions in the fourth quarter of 2011.

The slight increase in net sales in the Display Technologies segment in 2011, compared to 2010, was driven primarily by the favorable impact of approximately $300 million from movements in foreign exchange rates. Net sales of this segment are denominated in Japanese yen and, as a result, are susceptible to movements in the U.S. dollar-Japanese yen exchange rate. Volume growth in 2011 was more than offset by price declines, when compared to 2010.

When compared to 2010, the decrease in equity earnings from Samsung Corning Precision in 2011 reflected volume and price declines, offset somewhat by the favorable impact of approximately $120 million from movements in foreign exchange rates. Equity earnings of Samsung Corning Precision are impacted by movements in both the U.S. dollar - Japanese yen and U.S. dollar - Korean won exchange rates. The impact of the supply chain contraction and excess capacity has been more severe in Korea, resulting in higher price and volume declines at Samsung Corning Precision than at our wholly-owned business. Additionally, in the fourth quarter of 2011, although Samsung Corning Precision significantly reduced its glass pricing in light of the current state of glass supply in the industry, it did not recover market share that was lost in the third quarter. Due to these market dynamics, Samsung Corning Precision reduced its glass melting capacity, as described above. Equity earnings were also negatively impacted by higher taxes due to the partial expiration of a Korean tax holiday and the absence of a $61 million credit for our share of a revised tax holiday calculation agreed to by the Korean National Tax service recorded in 2010.

When compared to 2010, the decrease in net income in the Display Technologies segment in 2011 reflects the impact of lower equity earnings, price declines and a decrease in royalty income, partially offset by improved manufacturing efficiency and the favorable impact of approximately $230 million from foreign exchange rate movements. Net income was also negatively impacted by the absence of a pre-tax credit recorded in 2010 in the amount of $324 million as settlement of business interruption and property damage insurance claims.

A number of Corning’s patents and know-how are licensed to Samsung Corning Precision, as well as to third parties, which generates royalty income. Royalty income from Samsung Corning Precision decreased in 2011, when compared to 2010, reflecting the decline in sales volume at Samsung Corning Precision. Corning and Samsung Corning Precision have agreed that, for a five-year period commencing December 1, 2011, the applicable royalty rate will be reduced by approximately 50% compared to the prior five years. Refer to Note 7 (Investments) to the Consolidated Financial Statements for more information about related party transactions.

The increase in net sales in 2010 when compared to 2009 reflected an increase in volume of more than 25% and the positive impact of $179 million from movements in foreign exchange rates, offset by price declines of 8%. Volume gains in 2010 were led by strong growth in demand for LCD televisions outside of the United States, coupled with a replenishment of this industry’s supply chain.

Equity earnings of Samsung Corning Precision in 2010 increased by 32% when compared to 2009 due to volume gains of almost 20%, improved manufacturing performance, and by the positive impact of $90 million from movements in foreign exchange rates, offset somewhat by price declines of 7%. Equity earnings of Samsung Corning Precision are impacted by movements in both the U.S. dollar - Japanese yen and U.S. dollar - Korean won exchange rates. Equity earnings were also positively impacted by a $61 million credit for our share of a revised Samsung Corning Precision tax holiday calculation agreed to by the Korean National Tax service.

When compared to 2009, the increase in net income in 2010 primarily reflects the impact of the volume increases described above at both our wholly-owned business and Samsung Corning Precision and the impact of an insurance settlement for business interruption and property damage insurance claims, partially offset by price declines. The insurance settlement relates to two events in 2009 which impacted production at our LCD glass manufacturing facilities. In August 2009, an earthquake halted production at one of our LCD glass manufacturing facilities in Japan and, in October 2009, production at our facility in Taichung, Taiwan was impacted by a power disruption. We recorded a pre-tax credit in 2010 in the amount of $324 million as settlement of business interruption and property damage insurance claims related to these two events. Results also improved due to the absence of $31 million of restructuring charges impacting 2009 net income. Net income included royalty income from Samsung Corning Precision that was higher in 2010 when compared to 2009, reflecting the improvements in sales volume at Samsung Corning Precision. Net income in 2010 also includes the favorable impact of $182 million from movements in foreign exchange rates when compared to 2009.

The Display Technologies segment has a concentrated customer base comprised of LCD panel and color filter makers primarily located in Japan, China and Taiwan. In 2011, four customers of the Display Technologies segment, which individually accounted for more than 10% of segment net sales, accounted for a combined 77% of total segment sales. For 2010 and 2009, three customers of the Display Technologies segment, which individually accounted for more than 10% of segment net sales, accounted for 72% and 62%, respectively, of total segment sales when totaled. Our customers face the same global economic dynamics as we do in this market. While we are not aware of any significant customer credit issues, our near-term sales and profitability would be impacted if any of these significant customers were unable to continue to purchase our products.

In addition, Samsung Corning Precision’s sales are concentrated across a small number of its customers. In 2011, 2010 and 2009, sales to two LCD panel makers located in Korea accounted for approximately 93% of Samsung Corning Precision sales in each of those three years.

Corning has invested heavily to expand capacity to meet the projected demand for LCD glass substrates. In 2011, 2010 and 2009, capital spending in this segment was $1.3 billion, $497 million, and $552 million, respectively. We expect capital spending for 2012 to be approximately $800 million, of which approximately $400 million will be related to spending from 2011 capital projects.

In 2005 and 2004, several of Corning’s customers entered into long-term purchase and supply agreements in which Corning’s Display Technologies segment would supply large-size glass substrates to these customers over periods of up to six years. As part of the agreements, these customers agreed to advance cash deposits to Corning for a portion of the contracted glass to be purchased. We received our last deposit of $105 million in July 2007 and do not expect to receive additional deposits related to these agreements. During 2011, 2010 and 2009, we issued $28 million, $83 million, and $253 million, respectively, in credits that were applied to customer receivable balances when payments were due. As of December 31, 2011, no additional deposits have been received and all amounts previously owed as credits have been applied to customer receivable balances when payments were due. Refer to Note 11 (Other Liabilities) to the Consolidated Financial Statements for additional information.

We expect the overall LCD glass retail market to increase from 3.2 billion square feet in 2011 to approximately 3.6 billion square feet in 2012. We believe that the long-term market drivers will be LCD television growth, driven by growth of larger-sized LCD televisions and increased demand in emerging regions, as well as continued growth in the personal computer market.

In the first quarter of 2012, we expect volume at our wholly-owned business to be consistent with the fourth quarter of 2011. We anticipate volume at Samsung Corning Precision to be flat to down in the double-digits, depending upon the outcome of negotiations with a key customer, when compared to the fourth quarter of 2011. We expect cumulative double-digit price declines over the two-quarter period beginning in the fourth quarter of 2011.

The end market demand for LCD televisions, monitors and notebooks is dependent on consumer retail spending, among other things. We are cautious about the potential negative impacts that economic conditions, particularly a global economic recession, excess market capacity and world political tensions could have on consumer demand. While the industry has grown rapidly in recent years, economic volatility along with consumer preferences for panels of differing sizes, prices, or other factors may lead to pauses in market growth. Therefore, it is possible that glass manufacturing capacity may exceed demand from time to time. We may incur further charges in this segment to reduce our workforce and consolidate capacity. In addition, changes in foreign exchange rates, principally the Japanese yen, will continue to impact the sales and profitability of this segment.

In 2011, net sales of the Telecommunications segment increased when compared to 2010 due to higher sales in all of the segment’s product lines, led by fiber-to-the-premises, optical fiber and cable, and enterprise network products. Sales of fiber-to-the-premises products increased 39%, driven by initiatives in Canada, Europe and Australia. Optical fiber and cable sales growth reflected record volume, moderating price declines and an increase in sales of premium products. Sales also increased due to a small acquisition completed in the first quarter of 2011 and the positive impact from movements in foreign exchange rates in the amount of $20 million.

The increase in net income in 2011 when compared to 2010 reflects higher volume across all product lines and an increase in sales of higher margin products, coupled with a credit in the amount of $27 million for the decrease in a contingent liability associated with a first quarter acquisition. The increase in net income was offset slightly by the impact of higher raw materials and project costs associated with our initiatives in Australia and Europe. Movements in foreign exchange rates did not have a significant impact on the comparability of net income for the periods presented.

The Telecommunications segment has a concentrated customer base. In 2011, one customer of the Telecommunications segment accounted for 12% of total segment net sales. In 2010, one customer of the Telecommunications segment accounted for 15% of total segment net sales. In 2009, one customer of the Telecommunications segment accounted for 12% of total segment net sales.

Net sales for the segment were up when compared to 2009. Higher sales of enterprise network products and optical fiber and cable in North America and Europe were offset somewhat by lower sales of fiber-to-the-premises products and optical fiber and cable products in Asia, as well as the absence of sales from two businesses sold in 2009. Sales from the two businesses sold totaled $49 million. Net sales in 2010 were negatively impacted by $11 million from movements in foreign exchange rates, when compared to 2009.

The increase in net income in 2010 reflected the absence of restructuring charges from 2009, volume strength in enterprise network products, and the impact of improved manufacturing efficiency and cost reduction efforts. Net income of this segment in 2009 included $42 million of restructuring charges associated with the Company’s corporate-wide restructuring plan to reduce its global workforce. Net income in 2010 includes the favorable impact of $10 million from movements in foreign exchange rates, when compared to 2009.

We expect another strong year of sales growth in the Telecommunications segment in 2012, driven by an increase in global demand for our optical fiber and cable, fiber-to-the-premises and enterprise network products. In the first quarter of 2012, we expect net sales of this segment to increase between 5% and 10% when compared to the fourth quarter of 2011.

Changes in our customers’ expected deployment plans, or additional reductions in their inventory levels of fiber-to-the-premises products, could also affect sales levels. Should these plans not occur at the pace anticipated, our sales and earnings would be adversely affected.

When compared to 2010, net sales in the Environmental Technologies segment increased in 2011, primarily due to higher sales of diesel products. The increase was driven by an increase in truck production in the United States, implementation of European governmental regulations on light duty diesel vehicles, and the first stages of the implementation of off-road vehicle regulations in the United States. Sales of our automotive products also increased slightly in 2011, when compared to 2010, reflecting the continuing growth of worldwide automotive production. Net sales of this segment in 2011 were positively impacted by $13 million due to movements in foreign exchange rates when compared to 2010.

Net income in 2011 increased 181%, when compared to 2010, due to higher sales volume for our diesel products, combined with reduced air freight expense and improved manufacturing performance in both diesel and automotive product lines. The increase in net income was slightly offset by higher depreciation and project costs on manufacturing capacity expansion. Movements in foreign exchange rates negatively impacted the results of this segment in the amount of $3 million when compared to 2010.

The Environmental Technologies segment sells to a concentrated customer base of catalyzer and emission control systems manufacturers, who then sell to automotive and diesel engine manufacturers. Although our sales are to the emission control systems manufacturers, the use of our substrates and filters is generally required by the specifications of the automotive and diesel vehicle or engine manufacturers. For 2011, three customers of the Environmental Technologies segment, which individually accounted for more than 10% of segment sales, accounted for 85% of total segment sales. For 2010, three customers of the Environmental Technologies segment, which individually accounted for more than 10% of segment sales, accounted for 86% of total segment sales. For 2009, net sales to those same three customers accounted for 85% of total segment sales. While we are not aware of any significant customer credit issues with our direct customers, our near-term sales and profitability would be impacted if any individual customers were unable to continue to purchase our products.

Net sales for the Environmental Technologies segment in 2010 were up 38% when compared to 2009 and reflected higher volumes of both automotive and diesel products, offset somewhat by unfavorable foreign exchange rate movements. In 2009, automotive vehicle sales declined with the worldwide recession and production was significantly below vehicle sales volumes as manufacturers and dealers decreased inventories. In 2010, as automotive markets in the United States and Europe improved and China continued to expand, manufacturers and dealers increased inventories and production levels, resulting in a 25% increase in automotive production when compared to 2009. Diesel product sales increased 54% reflecting an improvement in the truck market in the United States and implementation of governmental regulations in Europe. Net sales of this segment in 2010 were negatively impacted by $11 million due to movements in foreign exchange rates when compared to 2009.

Net income in 2010 increased due to higher sales volumes and improvements in manufacturing performance, offset somewhat by higher freight costs, when compared to 2009. Net income in 2010 also reflected the absence of restructuring charges in comparison to the previous year. In 2009, net loss of this segment included $28 million of restructuring charges associated with the Company’s corporate-wide restructuring plan to reduce its global workforce in response to anticipated lower sales in 2009. Net income in 2010 included the negative impact of $9 million from movements in foreign exchange rates when compared to 2009.

We expect net sales of this segment to continue to be strong in 2012, due to strong growth in demand for diesel products in the United States freight market and related truck production, and continued implementation of governmental regulations of non-road regulations in the United States and Europe. In the first quarter of 2012, we expect net sales of this segment to be up slightly when compared to the fourth quarter of 2011.

Net sales in 2011 increased significantly in the Specialty Materials segment, driven by sales of Corning Gorilla Glass, which more than doubled when compared to last year, and a modest increase in semiconductor optics and aerospace and defense products. Movements in foreign exchange rates did not significantly impact net sales of this segment in 2011. Sales of Corning Gorilla Glass increased considerably, especially during the first nine months of the year, due to a combination of strong retail demand for handheld display devices, tablets and notebook computers, and increased usage of our glass on these devices. Although sales of Corning Gorilla Glass used in our large cover glass products increased in 2011 when compared to 2010, sales were significantly below our expectations in 2011 and are expected to be lower than forecasted in 2012. As a result, certain assets located in Japan used in the ion exchange process for the production of large cover glass were impaired in the fourth quarter of 2011. This asset group includes machinery and equipment used in the ion exchange process and facilities dedicated to the ion exchange process. The Specialty Materials segment reduced capacity for its Corning Gorilla Glass products, including the impairment of large cover glass assets, in the fourth quarter of 2011 as part of Corning’s worldwide capacity reduction of approximately 25%.

The slight increase in net loss in 2011 when compared to 2010 was driven by the large cover glass asset impairment charge in the amount of $130 million (pre-tax), offset by the considerable increase in sales volume of our Corning Gorilla Glass used in handheld display devices, tablets and notebook computers. Net income was also impacted somewhat by declines in manufacturing efficiency caused primarily by start-up costs for large cover glass and glass tank conversions necessary to increase manufacturing capacity for Corning Gorilla Glass in 2011, as well as the negative impact of movements in foreign exchange rates in the amount of $22 million.

For 2011, two customers of the Specialty Materials segment, which individually accounted for more than 10% of segment sales, accounted for 42% of total segment sales. For 2010, three customers of the Specialty Materials segment, which individually accounted for more than 10% of segment sales, accounted for 43% of total segment sales. In 2009, there were no individual customers that accounted for 10% or more of this segment’s net sales.

Net sales increased in 2010 due to higher sales of Corning Gorilla Glass and an increase in sales of display components and semiconductor optics and components when compared to 2009. Sales of Corning Gorilla Glass increased as the Company moved to capitalize on market opportunities for this product.

The lower net loss in 2010 was driven by higher sales of our Corning Gorilla Glass products and the absence of restructuring charges, offset somewhat by the costs associated with adding capacity. The net loss in 2009 includes $17 million of restructuring charges for the Company’s corporate-wide restructuring plan to reduce its global workforce. In 2010, movements in foreign exchange rates did not significantly impact net sales or net income of this segment.

For 2012, we expect sales of this segment to be led by Corning Gorilla Glass. In the first quarter of 2012, we expect net sales to be up slightly driven by Corning Gorilla Glass, when compared to the fourth quarter of 2011.

Net sales in 2011 increased when compared to 2010 due to a small acquisition completed in the fourth quarter of 2010 and higher sales in the segment’s existing product lines. Net sales in 2011 include the favorable impact of $7 million from movements in foreign exchange rates when compared to 2010.

Net income in 2011 was consistent with 2010, reflecting costs for manufacturing expansion projects, higher raw materials costs and the impact of the integration of the acquisition completed in 2010, offset by modest volume and price increases. Net income of this segment was positively impacted by $4 million due to movements in foreign exchange rates when compared to the prior year.

For 2011, two customers in the Life Sciences segment which individually accounted for more than 10% of total segment net sales collectively accounted for 39% of total segment sales. For 2010, two customers in the Life Sciences segment which individually accounted for more than 10% of total segment net sales collectively accounted for 37% of total segment sales. For 2009, two customers in the Life Sciences segment which individually accounted for more than 10% of total segment net sales collectively accounted for 45% of total segment sales.

The increase in net sales in 2010 was driven primarily by the acquisition of Axygen, which was completed in the third quarter of 2009, and a small acquisition completed in the fourth quarter of 2010. These acquisitions supported the Company’s strategy to expand Corning’s portfolio of life sciences products and enhance global customer access in this business, and accounted for $117 million of the increase in sales in 2010 when compared to 2009. The segment’s existing products lines also showed strong sales growth in 2010, improving $25 million when compared to 2009.

The improvement in net income in 2010 reflected the sales increases as described above, offset somewhat by higher cost of materials and expenses associated with the integration of Axygen. Net income for 2010 also reflected the absence of restructuring charges when compared to 2009. For 2009, net income of this segment included $8 million of restructuring charges associated with the Company’s corporate-wide restructuring plan. Movements in foreign exchange rates did not significantly impact the net sales or net income for this operating segment.

Sales of the Life Sciences segment for 2012 are expected to be strong, primarily due to an increase in organic sales and the impact of a small acquisition completed in the fourth quarter of 2011. In the first quarter of 2012, we expect net sales to be up approximately 10% when compared to the fourth quarter of 2011, driven partially by the impact of a full quarter of results for the small acquisition completed at the end of the fourth quarter of 2011.

All Other includes all other segments that do not meet the quantitative threshold for separate reporting. This group is primarily comprised of development projects that involve the use of various technologies for new products such as advanced flow reactors, thin-film photovoltaics and adjacency businesses in pursuit of thin, strong glass. This segment also includes results for certain corporate investments such as Samsung Corning Precision’s non-LCD glass businesses, Eurokera and Keraglass equity affiliates, which manufacture smooth cooktop glass/ceramic products, and Corsam Technologies LLC (Corsam), an equity affiliate established between Corning and Samsung Corning Precision to provide glass technology research. Refer to Note 7 (Investments) to the Consolidated Financial Statements for additional information about Samsung Corning Precision and related party transactions.

The increase in net loss in 2011 when compared to 2010 in this segment was driven by lower equity earnings from Samsung Corning Precision’s non-LCD glass businesses, partially offset by lower research, development and engineering expenses.

The decrease in the net loss in this segment for 2010 is primarily due to improved equity earnings from corporate investments and lower operating costs, offset by the costs of exiting our synthetic green laser program and the start-up costs for new business development projects.

The following items impacted Corning’s financing and capital structure during 2011 and 2010:

On October 5, 2011, Corning’s Board of Directors declared a 50% increase in the company’s quarterly common stock dividend. Corning’s quarterly dividend increased from $0.05 per share to $0.075 per share.

In December 2010, we amended and restated our revolving credit facility to provide a $1.0 billion committed, unsecured multi-currency revolving line of credit through December 2015. The facility includes two financial covenants: a leverage ratio and an interest coverage ratio. At December 31, 2011 and 2010, we were in compliance with both financial covenants.

Capital spending totaled $2.4 billion, $1.0 billion and $0.9 billion in 2011, 2010 and 2009, respectively. Capital spending increased significantly in 2011 when compared to 2010 and 2009, driven largely by several multi-year investment plans announced in 2010 that will increase manufacturing capacity in several of our reportable segments. Specifically, the increase in spending in 2011 was driven by construction costs for an LCD glass substrate facility in China for our Display Technologies segment and a capacity expansion project for Specialty Materials’ Corning Gorilla Glass in Japan. We expect our 2012 capital spending to be about $1.8 billion. Approximately $800 million will be allocated to our Display Technologies segment, of which approximately $400 million will be related to 2011 capital projects.

Net cash provided by operating activities decreased in 2011 when compared to 2010, driven largely by a non-recurring special dividend of almost $900 million received from Samsung Corning Precision in 2010 and a decrease in cash from changes in working capital. Additionally, in 2011, we received $66 million for the remainder of the settlement of business interruption and property damage insurance claims, a decrease of $193 million from the amount we received in 2010 as partial payment for these claims. These negative events were partially offset by a $350 million decrease in contributions to our defined benefit pension plans in 2011.

Net cash used in investing activities was higher in 2011 when compared to 2010 due to an increase in capital spending and two small acquisitions completed in 2011. Capital spending was driven primarily by capacity projects to support growth in demand in our Display Technologies and Specialty Materials segments. The increase in net cash used in investing activities was partially offset by higher cash received from short-term investments liquidations.

Net cash used in financing activities increased in 2011 when compared to 2010, driven by common stock repurchases and an increase in our dividend rate from $0.05 per share to $0.075 per share in the fourth quarter of 2011.

Operating cash flow increased significantly in 2010 when compared to 2009, driven largely by a special dividend of almost $900 million received from Samsung Corning Precision. We also recorded a credit in the amount of $324 million as settlement of business interruption and property damage insurance claims, and received cash totaling $259 million from our panel of insurance carriers representing a partial payment of this settlement. Additionally, we issued less credits against customer deposits in 2010 when compared to 2009. These positive events were partially offset by higher contributions to our defined benefit pension plan in 2010 and the decrease in cash from changes in working capital.

Net cash used in investing activities was higher in 2010 when compared to 2009 due to an increase in short-term investment purchases and higher capital expenditures, offset by lower costs for the acquisition of businesses.

Net cash provided by financing activities increased in 2010 primarily due to the increase in proceeds received from the exercise of stock options, offset somewhat by the net cash impact of financing activities.

We have defined benefit pension plans covering certain domestic and international employees. Our largest single pension plan is Corning’s U.S. qualified plan. At December 31, 2011, this plan accounted for 81% of our consolidated defined benefit pension plans’ projected benefit obligation and 91% of the related plans’ assets.

We have historically contributed to the U.S. qualified pension plan on an annual basis in excess of the IRS minimum requirements, and as a result, mandatory contributions are not expected to be required for this plan until some time after 2013. In 2011, we made no voluntary cash contributions to our domestic defined benefit pension plan and $5 million to our international pension plans. In 2010, we made voluntary cash contributions of $350 million to our domestic defined benefit pension plan and $5 million to our international pension plans.

In 2008, we experienced significant negative returns on our pension assets for our primary defined benefit plan as a result of deteriorating financial market conditions which increased pension expense for 2009 by $33 million. In 2011, 2010 and 2009, actual investment experience on the pension assets of our primary defined benefit plan was favorable driven by the performance of public equity markets, commodities and long duration fixed income securities.

Although we will not be subject to any mandatory contributions in 2012, we anticipate making voluntary cash contributions of up to $75 million to our U.S. pension plan and up to $30 million to our international pension plans in 2012.

Refer to Note 13 (Employee Retirement Plans) to the Consolidated Financial Statements for additional information.

Certain customers of our Display Technologies segment entered into long-term supply agreements and agreed to make advance cash deposits to secure supply of large-size glass substrates. The deposits were reduced through future product purchases, thus reducing operating cash flows in later periods as credits are applied for cash deposits received in earlier periods.

Between 2004 and 2007, we received a total of $937 million for customer deposit agreements. We received our last deposit of $105 million in 2007 and do not expect to receive additional deposits related to these agreements.

In 2011, 2010 and 2009, we issued credit memoranda which totaled $28 million, $83 million, and $253 million, respectively. These credit amounts were applied to customer receivable balances when payments were due. As of December 31, 2011, no additional deposits have been received and all amounts previously owed as credits have been applied to customer receivable balances when payments were due.

In the third quarter of 2011, Corning Hungary Data Services LLC and Samsung Electronics Corporation, as shareholders of Samsung Corning Precision, agreed to have Samsung Corning Precision increase its annual dividend to shareholders from 40% to 70% of its net income from the previous year, subject to the maintenance of minimum cash balances.

In 2009, we recorded charges of $228 million associated with a corporate-wide restructuring plan to reduce our global workforce in response to anticipated lower sales in 2009. The charge included costs for severance, special termination benefits, outplacement services, asset write-offs, and the impact of a curtailment loss for postretirement benefits. Total cash expenditures associated with these actions are expected to be approximately $150 million primarily related to termination benefits.

During 2011, 2010 and 2009, we made payments of $16 million, $66 million, and $89 million, respectively, related to employee severance and other exit costs resulting from restructuring actions. Refer to Note 2 (Restructuring, Impairment and Other Charges (Credits)) to the Consolidated Financial Statements for additional information.

Balance sheet and working capital measures are provided in the following table (dollars in millions):

We ended the fourth quarter of 2011 with over $5.8 billion of cash, cash equivalents and short-term investments. The Company has adequate sources of liquidity and we are confident in our ability to generate cash to meet existing or reasonably likely future cash requirements. Our cash, cash equivalents, and short-term investments are held in various locations throughout the world and are generally unrestricted. At December 31, 2011 approximately 65% of the consolidated amount was held outside of the U.S. Almost all of the amounts held outside of the U.S. are available for repatriation, subject to relevant tax consequences. We utilize a variety of tax planning and financing strategies to ensure that our worldwide cash is available in the locations in which it is needed. In the fourth quarter of 2010, we repatriated to the U.S. approximately $1.1 billion of 2010 earnings from certain foreign subsidiaries. We expect previously accumulated non-U.S. cash balances will remain outside of the U.S. In addition to the cash repatriated in 2010, we expect that we will meet U.S. liquidity needs through future cash flows, use of U.S. cash balances, external borrowings, or some combination of these sources.

Realized gains and losses for 2011 and 2010 were not significant. Volatility in financial markets may limit Corning’s access to capital markets and result in terms and conditions that by historical comparisons are more restrictive and costly to Corning. Still, from time to time, we may issue debt, the proceeds of which may be used to refinance certain debt maturities and for general corporate purposes. Refer to Note 3 (Available-for-Sale Investments) to the Consolidated Financial Statements for additional information.

During 2011, we repurchased 55 million shares of common stock for $780 million as part of a share repurchase program announced on October 5, 2011. There were no repurchases in 2010 or 2009.

We complete comprehensive reviews of our significant customers and their creditworthiness by analyzing their financial statements at least annually or more frequently for customers where we have identified a measure of increased risk. We closely monitor payments and developments which may signal possible customer credit issues. We currently have not identified any potential material impact on our liquidity resulting from customer credit issues.

Our major source of funding for 2012 and beyond will be our operating cash flow and our existing balances of cash, cash equivalents, short-term investments, as well as proceeds from any potential issuances of debt. We believe we have sufficient liquidity for the next several years to fund operations, our share repurchase program, the asbestos litigation, research and development, capital expenditures, scheduled debt repayments, and dividend payments.

Corning also has access to two credit facilities, a $1.0 billion unsecured committed revolving line of credit and a 4.0 billion Chinese Renminbi (RMB) credit agreement (approximately $635 million when translated to USD). These two credit facilities include two financial covenants: a leverage ratio and an interest coverage ratio. The required leverage ratio, which measures debt to total capital, is a maximum of 50%. At December 31, 2011 and 2010, our leverage using this measure was 10% and 11%, respectively. The required interest coverage ratio, which is an adjusted earnings measure as defined by our facility, compared to interest expense, is a ratio of at least 3.5 times. At December 31, 2011 and 2010, our interest coverage ratio using this measure was 41.7 times and 40.2 times, respectively. At December 31, 2011 and 2010, we were in compliance with both financial covenants.

Our debt instruments contain customary event of default provisions, which allow the lenders the option of accelerating all obligations upon the occurrence of certain events. In addition, the majority of our debt instruments contain a cross default provision, whereby a default on one debt obligation of the Company in excess of a specified amount, also would be considered a default under the terms of another debt instrument. As of December 31, 2011, we were in compliance with all such provisions.

Management is not aware of any known trends, demands, commitments, events or uncertainties that will result in or that are reasonably likely to result in a material increase or decrease in our liquidity. In addition, other than items discussed, there are no known material trends, favorable or unfavorable, in our capital resources and no expected material changes in the mix and relative cost of such resources.

Off balance sheet arrangements are transactions, agreements, or other contractual arrangements with an unconsolidated entity for which Corning has an obligation to the entity that is not recorded in our consolidated financial statements.

At the time a guarantee is issued, the Company is required to recognize a liability for the fair value or market value of the obligation it assumes. In the normal course of our business, we do not routinely provide significant third-party guarantees. Generally, third-party guarantees provided by Corning are limited to certain financial guarantees, including stand-by letters of credit and performance bonds, and the incurrence of contingent liabilities in the form of purchase price adjustments related to attainment of milestones. These guarantees have various terms, and none of these guarantees are individually significant.

Refer to Note 14 (Commitments, Contingencies, and Guarantees) to the Consolidated Financial Statements for additional information.

For variable interest entities, we assess the terms of our interest in each entity to determine if we are the primary beneficiary. The primary beneficiary of a variable interest entity is the party that absorbs a majority of the entity’s expected losses, receives a majority of its expected residual returns, or both, as a result of holding variable interests, which are the ownership, contractual, or other pecuniary interests in an entity that change with changes in the fair value of the entity’s net assets excluding variable interests.

Corning has identified four entities that qualify as variable interest entities. None of these entities is considered to be significant to Corning’s consolidated statements of position.

Corning does not have retained interests in assets transferred to an unconsolidated entity that serve as credit, liquidity or market risk support to that entity.

We are required, at the time a guarantee is issued, to recognize a liability for the fair value or market value of the obligation it assumes. In the normal course of our business, we do not routinely provide significant third-party guarantees. Generally, third-party guarantees provided by Corning are limited to certain financial guarantees, including stand-by letters of credit and performance bonds, and the incurrence of contingent liabilities in the form of purchase price adjustments related to attainment of milestones. These guarantees have various terms, and none of these guarantees are individually significant.

We have agreed to provide a credit facility related to Dow Corning. The funding of the Dow Corning credit facility will be required only if Dow Corning is not otherwise able to meet its scheduled funding obligations in its confirmed Bankruptcy Plan. The purchase obligations primarily represent raw material and energy-related take-or-pay contracts. We believe a significant majority of these guarantees and contingent liabilities will expire without being funded.

Corning has been named by the Environmental Protection Agency (the Agency) under the Superfund Act, or by state governments under similar state laws, as a potentially responsible party for 18 active hazardous waste sites. Under the Superfund Act, all parties who may have contributed any waste to a hazardous waste site, identified by the Agency, are jointly and severally liable for the cost of cleanup unless the Agency agrees otherwise. It is Corning’s policy to accrue for its estimated liability related to Superfund sites and other environmental liabilities related to property owned by Corning based on expert analysis and continual monitoring by both internal and external consultants. At December 31, 2011 and 2010, Corning had accrued approximately $25 million (undiscounted) and $30 million (undiscounted), respectively, for its estimated liability for environmental cleanup and related litigation. Based upon the information developed to date, management believes that the accrued reserve is a reasonable estimate of the Company’s liability and that the risk of an additional loss in an amount materially higher than that accrued is remote.

The preparation of financial statements requires us to make estimates and assumptions that affect amounts reported therein. The estimates that required us to make difficult, subjective or complex judgments, including future projections of performance and relevant discount rates, follow.

We are required to assess the recoverability of the carrying value of long-lived assets when an indicator of impairment has been identified. We review our long-lived assets in each quarter to assess whether impairment indicators are present. We must exercise judgment in assessing whether an event of impairment has occurred.

Manufacturing equipment includes certain components of production equipment that are constructed of precious metals, primarily platinum and rhodium. These metals are not depreciated because they have very low physical losses and are repeatedly reclaimed and reused in our manufacturing process over a very long useful life. Precious metals are reviewed for impairment as part of our assessment of long-lived assets. This review considers all of the Company’s precious metals that are either in place in the production process; in reclamation, fabrication, or refinement in anticipation of re-use; or awaiting use to support increased capacity. Precious metals are only acquired to support our operations and are not held for trading or other non-manufacturing related purposes.

Examples of events or circumstances that may be indicative of impairments include:

For purposes of recognition and measurement of an impairment loss, a long-lived asset or assets is grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. We must exercise judgment in assessing the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. For the majority of our reportable segments, we concluded that locations or businesses which share production along the supply chain must be combined in order to appropriately identify cash flows that are largely independent of the cash flows of other assets and liabilities.

For long-lived assets, when impairment indicators are present, we compare estimated undiscounted future cash flows, including the eventual disposition of the asset group at market value, to the assets’ carrying value to determine if the asset group is recoverable. This assessment requires the exercise of judgment in assessing the future use of and projected value to be derived from the assets to be held and used. Assessments also consider changes in asset utilization, including the temporary idling of capacity and the expected timing for placing this capacity back into production. If there is an impairment, a loss is recorded to reflect the difference between the assets’ fair value and carrying value. This may require judgment in estimating future cash flows and relevant discount rates and residual values in estimating the current fair value of the impaired assets to be held and used.

For an asset group that fails the test of recoverability described above, the estimated fair value of long-lived assets is determined using an “income approach”, “market approach”, “cost approach”, or a combination of one or more of these approaches as appropriate for the particular asset group being reviewed. All of these approaches start with the forecast of expected future net cash flows including the eventual disposition at market value of long-lived assets, and also considers the fair market value of all precious metals if appropriate for the asset group being reviewed. Some of the more significant estimates and assumptions in our analysis include: market size and growth, market share, projected selling prices, manufacturing cost and discount rate. Our estimates are based upon our historical experience, our commercial relationships, and available external information about future trends. We believe fair value assessments are most sensitive to market growth and the corresponding impact on volume and selling prices and that these are also more subjective than manufacturing cost and other assumptions. The Company believes its current assumptions and estimates are reasonable and appropriate.

In the event the current net book value of an asset group is found to be greater than the net present value of the cash flows derived from the asset group, we determine the actual fair market value of long-lived assets with the assistance from valuation appraisals conducted by third parties. The results of these valuations generally represent the fair market value of the asset group that will remain after any necessary impairment adjustments have been recorded. The impairment charge will be allocated to assets within the asset group on a relative fair value basis.

At December 31, 2011, the carrying value of precious metals was higher than the fair market value by $304 million. At December 31, 2010, the fair market value of precious metals was higher than our carrying value by $415 million. For the current reporting period, the undiscounted cash flow test shows that these precious metal assets, primarily in the Display Technologies segment, are recoverable as part of their asset groupings. The potential for impairment exists in the future if negative events significantly decrease the cash flow of our segments. Such events include, but are not limited to, a significant decrease in demand for products or a significant decrease in profitability in our Display Technologies or Specialty Materials segments.

During the fourth quarter of 2011, the Specialty Materials segment recorded a $130 million impairment charge related to certain assets located in Japan used in the ion exchange process for the production of large cover glass. Large cover glass is primarily used as a cover sheet of strengthened glass for frameless (bezel-less) LCD displays. The large cover glass impairment charge represents a write-down of assets specific to the glass-strengthening process for large size cover glass to their relative fair market values as of the date of impairment. This asset group includes machinery and equipment used in the ion exchange process and facilities dedicated to the ion exchange process.

For the year ended December 31, 2010, we did not identify any instances where the carrying values of our long-lived assets were not recoverable.

We are required to make certain subjective and complex judgments in assessing whether an event of impairment of goodwill has occurred, including assumptions and estimates used to determine the fair value of our reporting units.

Corning’s goodwill relates primarily to the Telecommunications, Specialty Materials and Life Sciences operating segments. Our annual goodwill recoverability assessment has historically been performed in the fourth quarter, as it is traditionally based on our annual strategic planning process. This process includes an extensive review of expectations for the long-term growth of our businesses and forecasted future cash flows. Our valuation method is an “income approach” using a discounted cash flow model in which cash flows anticipated over several periods, plus a terminal value at the end of that time horizon, are discounted to their present value using an appropriate rate of return. Our estimates are based upon our historical experience, our current knowledge from our commercial relationships, and available external information about future trends. Our latest detailed assessment was completed in the fourth quarter of 2009, and because we met the required criteria, was carried forward in 2010.

In the fourth quarter of 2011, we early adopted the guidance found in Accounting Standards Update No. 2011-08, which simplifies how an entity tests goodwill for impairment. It provides an option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The following summarizes our process to assess our goodwill balances for impairment:

The examples noted above are not all-inclusive, and the Company shall consider other relevant events and circumstances that affect the fair value of a reporting unit in determining whether to perform the first step of the goodwill impairment test.

We anticipate performing a detailed goodwill recoverability test in the second half of 2012 and every three years thereafter, unless indicators suggest otherwise.

Goodwill for the Telecommunications segment is tested at the reporting unit level which is also the operating segment level.

In the fourth quarter of 2009, we performed a quantitative goodwill recoverability test for this reporting unit, which was evaluated in the fourth quarter of 2010. The results of our impairment tests in 2009 and the update in 2010 indicated that the fair value of the reporting unit exceeded its book value by a significant amount. A discount rate of 9% was used in 2009. We determined a range of discount rates between 7% and 11% would not have affected our conclusion. In evaluating goodwill recoverability in the Telecommunications segment in the fourth quarter of 2011, we assessed qualitative factors in this reporting unit to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Based on our qualitative assessment, including but not limited to, consideration of the above factors, we concluded that it is more likely than not that there has not been a significant decrease in the amount that fair value exceeds the carrying value of goodwill in the Telecommunications reporting unit.

Goodwill for the Specialty Materials segment is tested at the reporting unit level, which is one level below an operating segment, as goodwill is the result of transactions associated with certain businesses within this operating segment.

In the fourth quarter of 2009, we performed a quantitative goodwill recoverability test for this reporting unit, which was evaluated in the fourth quarter of 2010. The results of our impairment tests in 2009 and the update in 2010 indicated that the fair value of the reporting unit exceeded its book value by a significant amount. A discount rate of 9% was used in 2009. We determined a range of discount rates between 7% and 11% would not have affected our conclusion. In evaluating goodwill recoverability in the fourth quarter of 2011, we assessed qualitative factors in this reporting unit to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Based on our qualitative assessment, including but not limited to, consideration of the above factors, we concluded that it is more likely than not that there has not been a significant decrease in the amount that fair value exceeds the carrying value of goodwill in the Specialty Materials reporting unit. Additionally, the large cover glass impairment incurred in the fourth quarter of 2011 did not cause a triggering event for goodwill impairment in this reporting unit because the cash flow related to this lower level asset group is not material to this reporting unit.

Goodwill for the Life Sciences segment is tested for impairment at the reporting unit level which is also the operating segment level.

In the fourth quarter of 2009, we performed a quantitative goodwill recoverability test for this reporting unit, which was evaluated in the fourth quarter of 2010. The results of our impairment tests in 2009 and the update in 2010 indicated that the fair value of the reporting unit exceeded its book value by a significant amount. A discount rate of 8% was used in 2009. We determined a range of discount rates between 6% and 10% would not have affected our conclusion. In evaluating goodwill recoverability in the fourth quarter of 2011, we assessed qualitative factors in this reporting unit to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Based on our qualitative assessment, including but not limited to, consideration of the above factors, we concluded that it is more likely than not that there has not been a significant decrease in the amount that fair value exceeds the carrying value of goodwill in the Life Sciences reporting unit.

As a result of the assessment of the qualitative factors, we have determined it is not necessary to perform the two-step goodwill impairment test on our reporting units.

Restructuring charges and impairments resulting from restructuring actions

We are required to assess whether and when a restructuring event has occurred and in which periods charges related to such events should be recognized. We must estimate costs of plans to restructure including, for example, employee termination costs. Restructuring charges require us to exercise judgment about the expected future of our businesses, of portions thereof, their profitability, cash flows and in certain instances eventual outcome. The judgment involved can be difficult, subjective and complex in a number of areas, including assumptions and estimates used in estimating the future profitability and cash flows of our businesses.

Restructuring events often give rise to decisions to dispose of or abandon certain assets or asset groups which, as a result, require impairment. We are required to carry assets to be sold or abandoned at the lower of cost or fair value. We must exercise judgment in assessing the fair value of the assets to be sold or abandoned.

We are required to exercise judgment about our future results in assessing the realizability of our deferred tax assets. Inherent in this estimation process is the requirement for us to estimate future book taxable income and possible tax planning strategies. These estimates require us to exercise judgment about our future results, the prudence and feasibility of possible tax planning strategies, and the economic environments in which we do business. It is possible that actual results will differ from assumptions and require adjustments to allowances.

Significant estimates and assumptions used in assessing the realizability of our deferred tax assets included: the long-term stabilization of U.S. income from forecasted royalty income in our Display Technologies operating segment, the long-term growth of our diesel business, and the future success of new products.

At December 31, 2011 and 2010, the carrying value of our equity method investments was $4.7 billion and $4.4 billion, respectively, with our two largest equity method investments comprising approximately 95% of the balance. We review our equity method investments for indicators of impairment on a periodic basis or if an event or circumstances change to indicate the carrying amount may be other-than-temporarily impaired. When such indicators are present, we then perform an in-depth review for impairment. An impairment assessment requires the exercise of judgment related to key assumptions such as forecasted revenue and profitability, forecasted tax rates, foreign currency exchange rate movements, terminal value assumptions, historical experience, our current knowledge from our commercial relationships, and available external information about future trends.

As of December 31, 2011 and 2010, we have not identified any instances where the carrying values of our equity method investments were not recoverable.

As required, Corning uses two kinds of inputs to determine the fair value of assets and liabilities: observable and unobservable. Observable inputs are based on market data or independent sources, while unobservable inputs are based on the Company’s own market assumptions. Once inputs have been characterized, we prioritize the inputs used to measure fair value into one of three broad levels. Characterization of fair value inputs is required for those accounting pronouncements that prescribe or permit fair value measurement. In addition, observable market data must be used when available and the highest-and-best-use measure should be applied to non-financial assets. Corning’s major categories of financial assets and liabilities required to be measured at fair value are short-term and long-term investments, certain pension asset investments and derivatives. These categories use observable inputs only and are measured using a market approach based on quoted prices in markets considered active or in markets in which there are few transactions.

Derivative assets and liabilities may include interest rate swaps and forward exchange contracts that are measured using observable quoted prices for similar assets and liabilities. In arriving at the fair value of Corning’s derivative assets and liabilities, we have considered the appropriate valuation and risk criteria, including such factors as credit risk of the relevant party to the transaction. Amounts related to credit risk are not material.

The Level 3 assets measured with unobservable inputs relate to certain pension asset investments and all long-lived assets fair valued on a nonrecurring basis related to the ion exchange process for the production of large cover glass, resulting in an impairment charge of $130 million, which was included in earnings for the period. Refer to Note 16 (Fair Value Measurements) of the Consolidated Financial Statements for further detail.

We are required to make judgments about future events that are inherently uncertain. In making determinations of likely outcomes of litigation matters, we consider the evaluation of legal counsel knowledgeable about each matter, case law, and other case-specific issues. See Part II – Item 3. Legal Proceedings for a discussion of the material litigation matters we face. The most significant matter involving judgment is the liability for asbestos litigation. There are a number of factors bearing upon our potential liability, including the inherent complexity of a Chapter 11 filing, our history of success in defending asbestos claims, our assessment of the strength of our corporate veil defenses, and our continuing dialogue with our insurance carriers and the claimants’ representatives. The proposed asbestos resolution (Amended PCC Plan) is subject to a number of contingencies. The approval of the Amended PCC Plan by the Bankruptcy Court is not certain and faces objections by some parties. Any approval of the Amended PCC Plan by the Bankruptcy Court is subject to appeal. For these and other reasons, Corning’s liability for these asbestos matters may be subject to changes in subsequent quarters. The estimate of the cost of resolving the non-PCC asbestos claims may also be subject to change as developments occur. Management continues to believe that the likelihood of the uncertainties surrounding these proceedings causing a material adverse impact to Corning’s financial statements is remote.

We are required to make judgments about future events that are inherently uncertain. In making determinations of likely outcomes of certain matters, including certain tax planning and environmental matters, these judgments require us to consider events and actions that are outside our control in determining whether probable or possible liabilities require accrual or disclosure. It is possible that actual results will differ from assumptions and require adjustments to accruals.

Pension and OPEB costs and obligations are dependent on assumptions used in calculating such amounts. These assumptions include discount rates, health care cost trend rates, benefits earned, interest cost, expected return on plan assets, mortality rates, and other factors. Actual results that differ from the assumptions are accumulated and amortized over future periods and, therefore, generally affect recognized expense and the recorded obligation in future periods. While management believes that the assumptions used are appropriate, differences in actual experience or changes in assumptions may affect Corning’s employee pension and other postretirement obligations and future expense.

As of December 31, 2011, the Projected Benefit Obligation (PBO) for U.S. pension plans was $2,855 million.

The following information illustrates the sensitivity to a change in certain assumptions for U.S. pension plans:

The above sensitivities reflect the impact of changing one assumption at a time. Note that economic factors and conditions often affect multiple assumptions simultaneously and the effects of changes in key assumptions are not necessarily linear. These changes in assumptions would have no effect on Corning’s funding requirements.

In addition, at December 31, 2011, a 25 basis point decrease in the discount rate would decrease stockholders’ equity by $104 million before tax, and a 25 basis point increase in the discount rate would increase stockholders’ equity by $101 million. In addition, the impact of greater than a 25 basis point decrease in discount rate would not be proportional to the first 25 basis point decrease in the discount rate.

The following table illustrates the sensitivity to a change in the discount rate assumption related to Corning’s U.S. OPEB plans:

The Company recognizes revenue when it is realized or realizable and earned. In certain instances, revenue recognition is based on estimates of fair value of deliverables as well as estimates of product returns, allowances, discounts, and other factors. These estimates are supported by historical data. While management believes that the estimates used are appropriate, differences in actual experience or changes in estimates may affect Corning’s future results.

Share-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period. Determining the fair value of stock-based awards at the grant date requires judgment, including estimating expected dividends. In addition, judgment is also required in estimating the amount of share-based awards that are expected to be forfeited. If actual results differ significantly from these estimates, share-based compensation expense and our results of operations could be impacted.

Refer to Note 1 (Summary of Significant Accounting Policies) to the Consolidated Financial Statements.

The statements in this Annual Report on Form 10-K, in reports subsequently filed by Corning with the Securities and Exchange Commission (SEC) on Form 10-Q, Form 8-K, and related comments by management that are not historical facts or information and contain words such as “believes,” “expects,” “anticipates,” “estimates,” “forecasts,” and similar expressions are forward-looking statements. These forward-looking statements involve risks and uncertainties that may cause the actual outcome to be materially different. Such risks and uncertainties include, but are not limited to:

We operate and conduct business in many foreign countries and as a result are exposed to movements in foreign currency exchange rates. Our exposure to exchange rates has the following effects:

We have foreign currency exposure to many currencies including the Japanese yen, Euro, New Taiwan dollar and Korean won. We selectively enter into foreign exchange forward contracts with durations generally 18 months or less to hedge our exposure to exchange rate risk on foreign source income and purchases. These hedges are scheduled to mature coincident with the timing of the underlying foreign currency commitments and transactions. The objective of these contracts is to reduce the impact of exchange rate movements on our operating results. We also enter into foreign exchange forward contracts when situations arise where our foreign subsidiaries or Corning enter into lending situations, generally on an intercompany basis, denominated in currencies other than their local currency. We do not hold or issue derivative financial instruments for trading purposes. Corning uses derivative instruments (forwards) to limit the exposure to foreign currency fluctuations associated with certain monetary assets and liabilities. These derivative instruments are not designated as hedging instruments for accounting purposes and, as such, are referred to as undesignated hedges. Changes in the fair value of undesignated hedges, along with foreign currency gains and losses arising from the underlying monetary assets or liabilities, are recorded in current period earnings in Other income, net in the consolidated statements of income.

Equity in earnings of affiliated companies has historically contributed a significant amount to our income from continuing operations. Equity in earnings of affiliated companies, net of impairments, were $1.5 billion and $2.0 billion in 2011 and 2010, respectively, with foreign-based affiliates comprising over 71% of this amount in 2011. Equity earnings from Samsung Corning Precision totaled $1.0 billion for 2011 and $1.5 billion for 2010. Exchange rate fluctuations and actions taken by management of these entities can affect the earnings of these companies.

We use a sensitivity analysis to assess the market risk associated with our foreign currency exchange risk. Market risk is defined as the potential change in fair value of assets and liabilities resulting from an adverse movement in foreign currency exchange rates. At December 31, 2011, with respect to open forward contracts, and foreign denominated debt with values exposed to exchange rate movements, a 10% adverse movement in quoted foreign currency exchange rates could result in a loss in fair value of these instruments of $275 million compared to $360 million at December 31, 2010. Specific to the Japanese yen, a 10% adverse movement in quoted yen exchange rates could result in a loss in fair value of these instruments of $241 million compared to $272 million at December 31, 2010. Specific to the Euro, a 10% adverse movement in quoted euro exchange rates could result in a loss in fair value of these instruments of $23 million compared to $83 million at December 31, 2010.

As we derive approximately 75% of our net sales from outside the U.S., our sales and net income could be affected if the U.S. dollar significantly strengthens or weakens against foreign currencies, most notably the Japanese yen and Euro. Our forecasts generally assume exchange rates during 2012 remain constant at January 2012 levels. As an example of impact changes in foreign currency exchange rates could have on our financial results, we compare 2011 actual sales in yen and Euro transaction currencies at an average currency exchange rate during the year to a 10% change in the currency exchange rate. A plus or minus 10% movement in the U.S. dollar - Japanese yen exchange rate would result in a change to 2011 net sales of approximately $410 million. A plus or minus 10% movement in the U.S. dollar - euro exchange rate would result in a change to 2011 net sales of approximately $96 million. Using 2011 net income attributable to Corning Incorporated as a percentage of net sales of 36%, we can estimate that a plus or minus 10% movement in the U.S. dollar - Japanese yen exchange rate would result in a change to 2011 net income attributable to Corning Incorporated of approximately $146 million. A plus or minus 10% movement in the U.S. dollar - euro exchange rate would result in a change to 2011 net income attributable to Corning Incorporated of approximately $34 million.

It is our policy to conservatively manage our exposure to changes in interest rates. At December 31, 2011, our consolidated debt portfolio contained less than 1% of variable rate instruments.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

Our principal executive and principal financial officers, after evaluating the effectiveness of our disclosure controls and procedures (as defined in the Securities Exchange Act of 1934 (Exchange Act) Rules 13a-15(e) or 15d-15(e)) as of the end of the period covered by this report, have concluded that based on the evaluation of these controls and procedures required by paragraph (b) of Exchange Act Rules 13a-15 or 15d-15, that our disclosure controls and procedures were effective.

Management is responsible for establishing and maintaining adequate disclosure controls and procedures and adequate internal control over financial reporting for Corning. Management is also responsible for the assessment of the effectiveness of disclosure controls and procedures and the effectiveness of internal control over financial reporting.

Disclosure controls and procedures mean controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the SEC’s rules and forms. Corning’s disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by Corning in the reports that it files or submits under the Exchange Act is accumulated and communicated to Corning’s management, including Corning’s principal executive and principal financial officers, or other persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Corning’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 accounting principles generally accepted in the United States of America. Corning’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 Corning’s assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America, and that Corning’s receipts and expenditures are being made only in accordance with authorizations of Corning’s management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of Corning’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 and procedures may deteriorate.

Management conducted an evaluation of the effectiveness of the system of internal control over financial reporting based on the framework in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that Corning’s internal control over financial reporting was effective as of December 31, 2011. The effectiveness of Corning’s internal control over financial reporting as of December 31, 2011, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included herein.

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of Corning Incorporated 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 accompanying index 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 Annual Report on Internal Control Over Financial Reporting,” appearing under Item 9A. 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 that 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.

The accompanying notes are an integral part of these consolidated financial statements.

Corning Incorporated is a provider of high-performance glass for notebook computers, flat panel desktop monitors, LCD televisions, and other information display applications; optical fiber and cable and hardware and equipment products for the telecommunications industry; ceramic substrates for gasoline and diesel engines in automotive and heavy duty vehicle markets; laboratory products for the scientific community and specialized polymer products for biotechnology applications; advanced optical materials for the semiconductor industry and the scientific community; and other technologies. In these notes, the terms “Corning,” “Company,” “we,” “us,” or “our” mean Corning Incorporated and subsidiary companies.

Our consolidated financial statements were prepared in conformity with generally accepted accounting principles in the U.S. and include the assets, liabilities, revenues and expenses of all majority-owned subsidiaries over which Corning exercises control.

The equity method of accounting is used for investments in affiliated companies that are not controlled by Corning and in which our interest is generally between 20% and 50% and we have significant influence over the entity. Our share of earnings or losses of affiliated companies, in which at least 20% of the voting securities is owned and we have significant influence but not control over the entity, is included in consolidated operating results.

We use the cost method to account for our investments in companies that we do not control and for which we do not have the ability to exercise significant influence over operating and financial policies. In accordance with the cost method, these investments are recorded at cost or fair value, as appropriate.

All material intercompany accounts, transactions and profits are eliminated in consolidation.

Certain prior year amounts have been reclassified to conform to the current-year presentation. These reclassifications had no impact on our results of operations, financial position, or changes in shareholders’ equity.

The preparation of financial statements requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements and related notes. Significant estimates and assumptions in these consolidated financial statements include estimates of fair value associated with goodwill and long-lived asset impairment tests, estimates of fair value of investments, equity interests, environmental and legal liabilities, income taxes and deferred tax valuation allowances, assumptions used in calculating pension and other postretirement employee benefit expenses and the fair value of stock based compensation. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be different from these estimates.

Revenue for sales of goods is recognized when a firm sales agreement is in place, delivery has occurred and sales price is fixed or determinable and collection is reasonably assured. If customer acceptance of products is not reasonably assured, sales are recorded only upon formal customer acceptance. Sales of goods typically do not include multiple product and/or service elements.

At the time revenue is recognized, allowances are recorded, with the related reduction to revenue, for estimated product returns, allowances and price discounts based upon historical experience and related terms of customer arrangements. Where we have offered product warranties, we also establish liabilities for estimated warranty costs based upon historical experience and specific warranty provisions. Warranty liabilities are adjusted when experience indicates the expected outcome will differ from initial estimates of the liability.

“Other income (expense), net” in Corning’s consolidated statements of income includes the following (in millions):

Research and development costs are charged to expense as incurred. Research and development costs totaled $563 million in 2011, $491 million in 2010, and $465 million in 2009.

The determination of the functional currency for Corning’s foreign subsidiaries is made based on the appropriate economic factors. For most foreign operations, the local currencies are generally considered to be the functional currencies. Corning’s most significant exception is our Taiwanese subsidiary, which uses the Japanese yen as its functional currency. For all transactions denominated in a currency other than a subsidiary’s functional currency, exchange rate gains and losses are included in income for the period in which the exchange rates changed.

Foreign subsidiary functional currency balance sheet accounts are translated at current exchange rates, and statement of operations accounts are translated at average exchange rates for the year. Translation gains and losses are recorded as a separate component of accumulated other comprehensive income (loss) in shareholders’ equity. The effects of remeasuring non-functional currency assets and liabilities into the functional currency are included in current earnings, except for those related to intra-entity foreign currency transactions of a long-term investment nature which are recorded together with translation gains and losses in other comprehensive income (loss) in shareholders’ equity.

Corning’s stock-based compensation programs include employee stock option grants, time-based restricted stock awards, time-based restricted stock units, performance based restricted stock awards, performance-based restricted stock units, and the Worldwide Employee Share Purchase Plan, as more fully described in Note 19 (Share-based Compensation) to the Consolidated Financial Statements.

The cost of stock-based compensation awards is equal to the fair value of the award at the date of grant and compensation expense is recognized for those awards earned over the vesting period, except as noted below. Corning estimates the fair value of stock based awards using a multiple-point Black-Scholes option valuation model, which incorporates assumptions including expected volatility, dividend yield, risk-free rate, expected term and departure rates.

Corning offered a Worldwide Employee Share Purchase Plan (WESPP), under which substantially all employees could elect to have up to 10% of their annual wages withheld to purchase our common stock. The purchase price of the stock was 85% of the end-of-quarter closing market price. On February 3, 2010, Corning’s Board of Directors approved the recommendation to terminate on-going WESPP contributions effective March 31, 2010 and the WESPP terminated in May 2010.

Cash equivalents consist of highly liquid investments that are readily convertible into cash. We consider securities with contractual maturities of three months or less, when purchased, to be cash equivalents. The carrying amount of these securities approximates fair value because of the short-term maturity of these instruments.

Our short-term investments consist of available-for-sale securities that are stated at fair value. Consistent with Corning’s cash investment policy, our short-term investments consist primarily of fixed-income securities. Preservation of principal is the primary principle of our cash investment policy that is carried out by limiting interest rate, reinvestment, security, quality and event risk. Our investments are generally liquid and all are investment grade quality. The portfolio is invested predominantly in U.S. Treasury securities and high quality short term government security money market funds. Unrealized gains and losses, net of tax, are computed on the first-in first-out basis and are reported as a separate component of accumulated other comprehensive loss in shareholders’ equity until realized. Realized gains and losses are recorded in other income (expense), net.

The Company’s allowance for doubtful accounts is determined based on a variety of factors that affect the potential collectability of the related receivables, including length of time receivables are past due, customer credit ratings, financial stability of customers, specific one-time events and past customer history. In addition, in circumstances where the Company is made aware of a specific customer’s inability to meet its financial obligations, a specific allowance is established. The majority of accounts are individually evaluated on a regular basis and appropriate reserves are established as deemed appropriate based on the above criteria. The remainder of the reserve is based on management’s estimates and takes into consideration the length of time receivables are past due, historical trends, market conditions, and the composition of the Company’s customer base.

The Company accrues for its environmental investigation, remediation, operating, and maintenance costs when it is probable that a liability has been incurred and the amount can be reasonably estimated. For environmental matters, the most likely cost to be incurred is accrued based on an evaluation of currently available facts with respect to each individual site, current laws and regulations and prior remediation experience. For sites with multiple potential responsible parties, the Company considers its likely proportionate share of the anticipated remediation costs and the ability of the other parties to fulfill their obligations in establishing a provision for those costs. Where no amount within a range of estimates is more likely to occur than another, the minimum amount is accrued. When future liabilities are determined to be reimbursable by insurance coverage, an accrual is recorded for the potential liability and a receivable is recorded related to the insurance reimbursement when reimbursement is virtually certain.

The uncertain nature inherent in such remediation and the possibility that initial estimates may not reflect the final outcome could result in additional costs being recognized by the Company in future periods.

Inventories are stated at the lower of cost (first-in, first-out basis) or market.

Land, buildings, and equipment, including precious metals, are recorded at cost. Depreciation is based on estimated useful lives of properties using the straight-line method. Except as described in Note 2 (Restructuring, Impairment and Other Charges (Credits)) to the Consolidated Financial Statements related to accelerated depreciation arising from restructuring programs and Note 9 (Property, Net of Accumulated Depreciation) of the Consolidated Financial Statements related to the depletion of precious metals, the estimated useful lives range from 10 to 40 years for buildings and 2 to 20 years for equipment.

Included in the subcategory of equipment are the following types of assets (excluding precious metals):

Manufacturing equipment includes certain components of production equipment that are constructed of precious metals. These assets are not depreciated because they have very low physical losses and are repeatedly reclaimed and reused in our manufacturing process over a very long useful life. We treat the physical loss of precious metals in the manufacturing and reclamation process as depletion and account for these losses as a period expense based on actual units lost. Precious metals are integral to many of our glass production processes. They are only acquired to support our operations and are not held for trading or other purposes.

Goodwill is the excess of cost of an acquired entity over the amounts assigned to assets acquired and liabilities assumed in a business combination. Goodwill is reviewed for indicators of impairment quarterly or if an event occurs or circumstances change that indicates that the carrying amount may be impaired. Impairment testing for goodwill is done at a reporting unit level. Reporting units are either operating segments or one level below the operating segment. Goodwill relates to and is assigned directly to a specific reporting unit. We anticipate performing a detailed goodwill recoverability assessment in the second half of 2012 and every three years thereafter, unless indicators suggest otherwise.

The qualitative process includes an extensive review of expectations for the long-term growth of our businesses and forecasting future cash flows. If we are required to perform the two-step impairment analysis, our valuation method is an “income approach” using a discounted cash flow model in which cash flows anticipated over several periods, plus a terminal value at the end of that time horizon, are discounted to their present value using an appropriate rate of return. Our estimates are based upon our historical experience, our current knowledge from our commercial relationships, and available external information about future trends. If the fair value is less than the carrying value, a loss is recorded to reflect the difference between the fair value and carrying value.

Other intangible assets include patents, trademarks, and other intangible assets acquired from an independent party. Such intangible assets have a definite life and are amortized on a straight-line basis over estimated useful lives ranging from 4 to 50 years.

We review the recoverability of our long-lived assets, such as plant and equipment and intangible assets, when events or changes in circumstances occur that indicate that the carrying value of the asset or asset group may not be recoverable. When impairment indicators are present, we compare estimated undiscounted future cash flows, including the eventual disposition of the asset group at market value, to the assets’ carrying value to determine if the asset group is recoverable. For an asset group that fails the test of recoverability, the estimated fair value of long-lived assets is determined using an “income approach” that starts with the forecast of all the expected future net cash flows including the eventual disposition at market value of long-lived assets, and also considers the fair market value of all precious metals. We assess the recoverability of the carrying value of long-lived assets at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. If there is an impairment, a loss is recorded to reflect the difference between the assets’ fair value and carrying value. Refer to Note 2 (Restructuring, Impairment and Other Charges (Credits)) to the Consolidated Financial Statements for more detail.

Shares of common stock repurchased by us are recorded at cost as treasury stock and result in a reduction of shareholders’ equity in the consolidated balance sheets. From time to time, treasury shares may be reissued as contributions to our employee benefit plans and for the retirement or conversion of certain debt instruments. When shares are reissued, we use an average cost method for determining cost. The difference between the cost of the shares and the reissuance price is added to or deducted from additional paid-in capital.

The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to operating loss and tax credit carry forwards and for differences between the carrying amounts of existing assets and liabilities and their respective tax bases.

The effective income tax rate reflects our assessment of the ultimate outcome of tax audits. In evaluating the tax benefits associated with our various tax filing positions, we record a tax benefit for uncertain tax positions using the highest cumulative tax benefit that is more likely than not to be realized. Adjustments are made to our liability for unrecognized tax benefits in the period in which we determine the issue is effectively settled with the tax authorities, the statute of limitations expires for the return containing the tax position or when more information becomes available. Our liability for unrecognized tax benefits, including accrued penalties and interest, is included in other accrued liabilities and other long-term liabilities on our consolidated balance sheets and in income tax expense in our consolidated statements of earnings.

Discrete events such as audit settlements or changes in tax laws are recognized in the period in which they occur. Valuation allowances are established when management is unable to conclude that it is more likely than not that some portion, or all, of the deferred tax asset will ultimately be realized.

The Company is subject to income taxes in the United States and in numerous foreign jurisdictions. No provision is made for U.S. income taxes on the undistributed earnings of wholly-owned foreign subsidiaries because substantially all such earnings are indefinitely reinvested in those companies. Provision for the tax consequences of distributions, if any, from consolidated foreign subsidiaries is recorded in the year in which the earnings are no longer indefinitely reinvested in those subsidiaries.

Our equity method investments are reviewed for impairment on a periodic basis or if an event occurs or circumstances change that indicate the carrying amount may be impaired. This assessment is based on a review of the equity investments’ performance and a review of indicators of impairment to determine if there is evidence of a loss in value of an equity investment.
